Our understanding of lineage decisions in early human development has been greatly aided by embryonic stem cell lines, which avoid many of the practical and ethical difficulties of in vivo material. A new paper in Development exploits naïve human embryonic stem cells to generate in vitro models for the extra-embryonic endoderm. We caught up with first authors Madeleine Linneberg-Agerholm and Yan Fung Wong, and their supervisor Josh Brickman, Professor of Stem Cell and Developmental Biology at the Novo Nordisk Foundation Center for Stem Cell Biology (DanStem) in Copenhagen, to hear more about the work.

The urban fabric of European cities is subject to significant pressures from human activity and climate change. The devastating effects of climate change on urban environments threaten the quality of life of citizens and ecosystems. In particular, historic and dense-tissue cities face challenges in adapting their established urban fabric devoid of green areas. The lack of green spaces for social gatherings becomes a critical issue in addressing the climate and environmental crisis. Dense cities such as Barcelona and Copenhagen are promptly responding to the climate emergency through adaptation plans. This essay identifies the 19th-century neighbourhood of San Salvario in Turin, as a case study to develop a morphological analysis aimed at proposing nature-based strategies to improve the adaptation potential and resilience. The design elements identified in the two best practices cities inspire hypothesizing replicable architectural solutions in dense urban contexts such as the study area under consideration. Finally, the paper addresses the limitations arising from the lack of holistic strategic planning, which in the case of Turin is based on fragmented interventions disconnected from the existing ecological network rather than on a long-term plan. The paper also reflects on the need to include additional assessments of ecosystem services, taking into account their economic valuation. [ABSTRACT FROM AUTHOR]

In this paper, we discuss quantum formalisms that do not use the axiom of choice. We also consider the fundamental problem that addresses the (in)correctness of having the complex numbers as the base field for Hilbert spaces in the København interpretation of quantum theory, and propose a new approach to this problem (based on the Lefschetz principle). Rather than a theorem–proof paper, this paper describes two new research programs on the foundational level, and focuses on basic open questions that arise in these programs. [ABSTRACT FROM AUTHOR]

This paper introduces the open-source Urban Belonging (UB) toolkit, designed to study place attachments through a combined digital, visual and participatory methodology that foregrounds lived experience. The core of the toolkit is the photovoice UB App, which prompts participants to document urban experiences as digital data by taking pictures of the city, annotating them, and reacting to others' photos. The toolkit also includes an API interface and a set of scripts for converting data into visualizations and elicitation devices. The paper first describes how the app's design specifications were co-created in a process that brought in voices from different research fields, planners from Gehl Architects, six marginalized communities, and citizen engagement professionals. Their inputs shaped decisions about what data collection the app makes possible, and how it mitigates issues of privacy and visual and spatial literacy to make the app as inclusive as possible. We document how design criteria were translated into app features, and we demonstrate how this opens new empirical opportunities for community engagement through examples of its use in the Urban Belonging project in Copenhagen. While the focus on photo capture animates participants to document experiences in a personal and situated way, metadata such as location and sentiment invites for quali-quantitative analysis of both macro trends and local contexts of people's experiences. Further, the granularity of data makes both a demographic and post-demographic analysis possible, providing empirical ground for exploring what people have in common in what they photograph and where they walk. And, by inviting participants to react to others' photos, the app offers a heterogeneous empirical ground, showing us how people see the city differently. We end the paper by discussing remaining challenges in the tool and provide a short guide for using it. [ABSTRACT FROM AUTHOR]

The process of optimizing energy production is becoming increasingly important with the development and use of RES and energy efficiency measures. Given that these are optimization processes that require taking into account several indicators according to which the set of optimal technologies for energy production will be ranked, and take their percentage share in the total percentage of energy supply. Indicators describing the process of energy production and utilization include technological, environmental, economic, energy, and limiting domains of their application. From that aspect, when the energy supply process is optimized from several possible alternatives according to the optimization factors defined in this way and the percentage of participation from each is calculated, a very realistic picture of the optimal energy mix of a state or local community is obtained. In this paper, a comparison of the energy mix for Copenhagen, Denmark and Banja Luka, Bosnia and Herzegovina is made. The process of comparing energy mixes was made possible by a previously developed mathematical model for optimizing and searching for an optimal energy mix based on the compromise ranking method, also known as the VIKOR, as well as entropy and analytic hierarchy process methods for defining weight values of criteria describing energy mix. Since we know that the introduction of new RES and the replacement of fossil fuels with them is a process of transition of existing energy sectors, the approach presented in this paper would greatly facilitate the transition process itself.

Progressive climate change brings many challenges to cities, which, in an effort to meet them, are looking for ways to create a built environment that is resilient and adapted to change. The subject of the paper is the urban nature, which, skillfully used and introduced into public space, becomes an active tool for adapting cities to future climate conditions. The aim of the paper is to identify key solutions to introduce urban nature into public spaces in the context of model strategic planning and urban design undertaken in cities. To this aim, development strategies, with a particular focus on urban nature, developed in Copenhagen over the past few years, were researched. Of those identified, the directions and actions that address public spaces and holistically link the needs of the built and natural environment with the needs of humans were selected. Research leads to a comparison of the model strategies and selected implementations used in Copenhagen, prioritizing the urban nature, with examples of strategic development policies and adaptation projects implemented in the public spaces of selected Polish cities. The result of the research is an assessment of the completeness of climate change adaptation measures undertaken in Poland, using the potential of urban nature in public spaces and recommendations for updating planning and strategic documents based on Copenhagen's model solutions.

Many modern navigation systems and map-based services do not only provide the fastest route from a source location $s$ s to a target location $t$ t but also provide a few alternative routes to the users as more options to choose from. Consequently, computing alternative paths has received significant research attention. However, it is unclear which of the existing approaches generates alternative routes of better quality because the quality of these alternatives is mostly subjective. Motivated by this, in this paper, we present a user study conducted on the road networks of Melbourne, Dhaka and Copenhagen that compares the quality (as perceived by the users) of the alternative routes generated by four of the most popular existing approaches including the routes provided by Google Maps. We also present a web-based demo system that can be accessed using any internet-enabled device and allows users to see the alternative routes generated by the four approaches for any pair of selected source and target. We report the average ratings received by the four approaches and our statistical analysis shows that there is no credible evidence that the four approaches receive different ratings on average. We also discuss the limitations of this user study and recommend the readers to interpret these results with caution because certain factors may have affected the participants’ ratings.

The study objects to lay out a lucid perspective on "how any securitizing move occurs successfully" an issue that was non-rigidly theorized in the Copenhagen version of securitization, in line with current debates. To this end, the vague criteria as follows, set by the classical cadre of the Copenhagen School are problematized: actors have to couch the issue as an existential threat requiring exceptional executive powers, and, if the audience accepts the securitizing move, the case is established as a security issue beyond the routine procedure of politics. Considering this conservative cycle, the first claim of this paper is that the politics of "audience acceptance" is not adequately determined in theory. The second is that the classical variants' persistence in the transition to "exceptional security policy" in the operation of securitization, ignoring its insecure nature, reduces the theory to a given and fixed understanding of security such as "security=exceptionalism." Premised on these arguments, the paper proposes an overarching systematized thought that empowers the audience's role; does not exclude "exceptional measures" but also inserts into "normalized exceptional" and even "routine responses" as actions.

In 1688 two sculptural fragments, a head of bearded man and a head of an unbearded youth, arrived in Copenhagen, sent from Athens as a gift to King Christian 5. They were placed in the Royal Kunstkammer, their provenance given as the Temple of Artemis in Ephesos, one of the Seven Wonders of the World. Almost a hundred and fifty years later, in the early 1820's they were noticed and studied by two scholars independently visiting the Kunstkammer. However, both concluded that the two heads belonged to one of the metopes decorating the south side of the Parthenon temple on the Acropolis in Athens, showing fighting between Greeks and the mythical Centaurs, part man and part horse. In the 1830's another sculptural fragment, a horse's hoof, obtained through the German archaeologist and state antiquary of Greece, Ludwig Ross, reached Copenhagen. It was forwarded by the Danish consul to Athens, C.T. Falbe, as a gift to King Christian 8. The inventory reads: '... was found on the Acropolis near the Parthenon temple and is supposed to belong to one the Centaurs on the metopes.' The present paper focuses solely on the head of the Centaur. A brown stain was noticed on the Parthenon marbles as early as 1830 by the British Museum and has ever since eluded a deeper understanding of its genesis despite many investigations and attempts of analyses. A quite similar brown stain can be observed on the Centaur's head in Copenhagen as well. The present study reports analyses by LA-ICP-MS, SEM–EDX, µXRD, GC–MS, and LC–MS-MS, as well as optical microscopy of five small samples sequestered in 1999 from the Centaur head curated by the National Museum of Denmark. Our analyses show that the brown stain consists of two consecutively added surficial layers of the calcium oxalate minerals whewellite and weddellite. Despite a thorough search using proteomics, we have found no viable organic precursor material for the oxalates. Our results do not solve the mystery of the formation of the brown stain, but they do further qualify the structure and characterization of the brown stain. [ABSTRACT FROM AUTHOR]

Schedule conformance depends on construction activities starting and finishing on time. However, construction activities are often delayed because construction flows necessary to start their execution are unavailable. Construction flows can be classified into: labor, equipment, workspace, materials, precedence, information, and external. Current construction models do not formally represent, measure, and track all flow types. Hence, field managers lack formal methods for managing flows and instead rely on their intuition and experience managing them. This paper presents a construction model based on activities and flows called the activity–flow model (AFM). The AFM formally represents the activities, the flows, and their interactions. The AFM was validated prospectively through its implementation on three building projects that were in different phases (foundations, core and shell, and finishing), at different geographic locations (Bogota, Copenhagen, and Lima), and used different planning and control methods (master schedule and weekly planning, last planner system, and location-based management system). The AFM was able to represent all the activities and flows in the test projects, track variations of activities and flows, and quantify activity and flow variability. Field managers can use the metrics enabled by the AFM to plan and control the project. Such proactive flow management can help field managers improve flow readiness, which should reduce activity delays and improve schedule conformance. [ABSTRACT FROM AUTHOR]

The ongoing digitalization of critical infrastructures enables more efficient processes, but also comes with new challenges related to potential cyber-physical attacks or incidents. To manage their associated risk, a precise and systematic framework should be adopted. This paper describes a general methodology that is consistent with the Risk Management ISO (31000-2018) and builds on specific tools developed within the H2020 digital-water.city (DWC) project. The approach has been demonstrated for a digital solution of the DWC project that allows to visualize inflow predictions for the Wastewater Treatment Plant (WWTP) in the city of Copenhagen. Specifically, the risk assessment and risk treatment steps are demonstrated in the case of the spoofing of the web interface where misleading forecast data may turn into fallacious maintenance schedules for the operators. The adopted methodology applied to the selected use case led to the identification of convenient measures for risk mitigation. [ABSTRACT FROM AUTHOR]

Airports play a vital role in the air transport industry value chain, acting as the interface point between the air and surface transport modes. However, substantial volumes of waste are produced as a by-product of the actors' operations. Waste management is therefore becoming especially important to airports. Using a qualitative and quantitative case study research approach, this paper has examined the waste management strategies and systems at Copenhagen Airport, Scandinavia's major air traffic hub, from 1999 to 2016. The two major sources of waste at Copenhagen Airport are the waste generated from aircraft serving the airport and the waste arising from ground activities undertaken in the land and airside precincts. The growth in passengers and aircraft movements has had a concomitant impact on the volume of waste generated. Swept waste and sludge are processed by an external provider. Waste generated in the passenger terminals and the airport operator's facilities is handled at a central container station, where it is sorted for incineration, recycling or for landfill. The environmental impact of the waste produced at the airport is mitigated through the recycling of waste wherever possible. [ABSTRACT FROM AUTHOR]

Complementarity is the central component of the so-called Copenhagen interpretation of quantum mechanics, which Niels Bohr first presented at the Como and Solvay Conferences in 1927. The content of Bohr's speech was published in an article entitled "the quantum postulate and recent development of Atomic Theory" in 1928. The purpose of this study is to formulate Bohr's philosophical approaches by content analysis of his paper (1928) related to complementarity. The research method is based on the conceptual analysis of the content and text of this paper (1928) from which conceptual inferences can be deduced, and based on them, philosophical approaches are tried to be formulated. Finally, the four philosophical approaches including Unificationism, empiricism (positivistic and metaphysical), anticausality and indeterministic, as well as anti-realism can be formulated. In addition, for more accurate inferences, we need to refer to the following works of Bohr, or in other words, "Bohr from Bohr's point of view". [ABSTRACT FROM AUTHOR]

Background: The purpose of this case study is to describe how a vulnerable group of patients can be included in research. The activities, challenges, lessons learned, and reflections on the importance of patient involvement in research for 5 years (2016–2021) at the adolescent and young adult (AYA) cancer support facility, Kræftværket, are reported. Main body: A patient panel at Kræftværket, the Youth Panel has multiple aims, one of which is the ability to perform patient involvement in research, with the goal of achieving research of high quality. We here describe how Patient and Public involvement (PPI) can be customized to AYAs in a cancer trajectory, who face many challenges, including those in the physical, psychological, and social domains. During 2016–2021, Youth Panel meetings were planned every third month but interrupted during the COVID-19 pandemic. With a flexible structure and a dynamic panel including 10–15 varying AYAs in a cancer trajectory, engagement and involvement have been maintained. Eight research topics were investigated, seven of which were discussed and confirmed to be important by the Youth Panel. Out of eight topics, three were raised by patients, and five by researchers. One was not discussed due to COVID-19. Some of the challenges we have experienced were related to the flexible meeting structure and the differing expectations and priorities as well as the impact of COVID-19. However, we experienced that patient involvement is possible in the field of AYA oncology if a trusting environment is created. A key finding in our case study was, that without a national Danish PPI program and no defined international standard for PPI in AYA cancer research yet, we were able to give patients the possibility to give input to researchers on topics where research is missing. Conclusion: Here, we demonstrate how patient involvement in research has been performed at an AYA cancer facility, Kræftværket, during a 5-year period. We encourage others to perform patient-involving research, even in challenging populations. Ideally this must follow international standards for PPI in AYA cancer research when such exist to improve research with crucial insight from patients. Plain English resume: In this paper, we describe patient involvement in research at Kræftværket, a youth support center and social organization for AYAs in a cancer trajectory. The center is located at The University Hospital Rigshospitalet in Copenhagen, Denmark. Youth panel meetings are Kræftværkets' most central patient involvement activity, and one of its aims is to facilitate high-quality patient-initiated research. AYA cancer patients are a vulnerable group facing huge psycho-social challenges and symptoms that make normal functioning difficult. Therefore, the youth panel is designed to be flexible in its structure, so participants do not have to commit themselves as permanent members. The youth panel meets four times a year, and during the period 2016–2021, it has been involved in eight research topics. Challenges include the flexible meeting structure, different expectations, and priorities as well as the impact of COVID-19. However, patient involvement has been possible because of a trusting environment with strong nurse-led support for the participants. We hope to encourage others to argue for and carry out meaningful patient-involving research to improve tomorrow's quality of AYA cancer care. [ABSTRACT FROM AUTHOR]

Background: The incidents of Head and Neck Cancer (HNC) are rising worldwide, suggesting that this type of cancer is becoming more common. The foreseen growth of incidents signifies that future rehabilitation services will have to meet the needs of a wider population. Objective: The aim of this paper is to explore the needs of patients, caregivers and healthcare professionals during HNC rehabilitation. Methods: This paper reports the empirical findings from a case study that was conducted in a cancer rehabilitation center in Copenhagen to elicit the needs of HNC cancer patients, informal caregivers and healthcare professionals. Results: Four areas of needs during the rehabilitation process were identified: service delivery, emotional, social and physical needs. Service delivery needs and emotional needs have been identified as the most prevalent. Conclusions: Stakeholders' needs during the rehabilitation process were found to be interrelated. All stakeholders faced service delivery challenges in the form of provision and distribution of information, including responsibilities allocation between municipalities, hospitals and rehabilitation services. Emotional and social needs have been reported by HNC patients and informal caregivers, underlining the importance of inclusion of all actors in the design of future healthcare interventions. Connected Health (CH) solutions could be valuable in provision and distribution of information. [ABSTRACT FROM AUTHOR]

This paper is based on 8 months of sociological participatory fieldwork at the office of Gottlieb Paludan Architects, following the design process of a new concourse area for Ny Ellebjerg Station in Copenhagen, Denmark. The study aims to trace what presence users with physical disabilities possessed during a design process in which they were not physically present or explicitly involved. The study bases its findings on the visual material produced during the design process by the employees of Gottlieb Paludan Architects as well as the thoughts and discussions of practitioners. Drawing on actor-network theory, the study describes and analyses these human and non-human actors as they constitute and contribute to the design process. The study finds that users with physical disabilities were present within the design process through an implicit generalized presence and an explicit required presence. Generalized presence refers to those instances where the architectural qualities that were strived for in the project implicitly aligned with the needs of users with physical disabilities. Required presence refers to those instances during the design process where accessibility demands from client guidelines or building regulations played an important role. [ABSTRACT FROM AUTHOR]

In this paper, we present the project, Community Drive, as well as the theoretical and empirical background on which the project is based. Through technical and humanistic collaboration, the project aims to create models that allow children and young people to participate in overcoming future challenges in cities by becoming active and contributing participants in research and development efforts. Further, the project contributes knowledge about community-driven game tools, user-driven big data and the Internet of Things and their connection with intelligent and socially responsible urban development. The project is conducted in cooperation with the city of Copenhagen, local schools and Aalborg University. Community Drive involves students, aged 10-13, attending schools in deprived neighbourhoods near Aalborg University Copenhagen in southern Copenhagen. This area is characterised by a high rate of unemployment, low income and residents with little or no education. As a result, resources have been allocated for reconditioning the subsidised housing in this area. In this paper, we discuss the ways in which Community Drive, initiated in May 2018, is based on the results of pilot projects conducted from 2014 to 2017. Overall, these studies showed that tasking students with changing their living conditions by redesigning their neighbourhoods is a strong motivational factor. During the redesign process, students were able to construct game-based models of various residents' needs and argue for redesigns based on their knowledge about the area and the ability of certain designs to fulfil the needs of various groups of residents living in the area. We also present initial results from collaboration workshops between schools and professional external local partners. These results show that three themes are central for the collaboration process: building local contact, meaningful local ownership and real challenges and applicable solutions.

The article offers information on the fourth Copenhagen Conference, entitled "Emerging Multinationals: Outward Investment from Emerging Economies," to be held October 9-10, 2014 in Copenhagen, Denmark.

On 26 November 1740 the Danish royal family took up residence in the new Christiansborg Palace, located at the center of Copenhagen. As was the case for many other European court residences, construction, especially on the interiors, continued well after the inauguration of the palace. In this paper we look at examples of different notions of privacy and how the spatial organization of the first Christiansborg Palace contributed to the living experiences of the residents. While the surviving floor plans show a magnificent residence, the actual living situation must have differed considerably from the ideal evoked by these widespread drawings. The inventories depict a residence that is only partly used, with empty rooms and unfinished spatial sequences. The most ceremonial routes in particular, including the great hall or the king's staircase, were incomplete. The hierarchical structure established by the succession of rooms was hence nullified by shortcuts and the daily use of actual accesses and connections. Court instructions and reports of foreign visits give more insight into these accesses that were ad hoc or improvised. [ABSTRACT FROM AUTHOR]

The surge of developing Sectoral Qualifications Frameworks and their use in vocational training for the past few years can be illustrated by a Frontex2 initiative in the extensive area of border and coast guarding. The EU authorities have tried to promote and model a harmonised approach to course design and training based on the European Qualifications Framework and Bologna and Copenhagen processes, matching the developments in general education across Europe. The aim of this paper is to examine the particular case of Sectoral Qualifications Framework for Border and Coast Guarding, focusing on vocational specificities, recent developments and practical applications at the level of course design. The corpus of the analysis consists of a specific training program in course design developed by Frontex in the past 5 years. The content analysis focuses on two main tiers: recent developments in SQF course design and applications of SQF in border and coast guarding course design. Each of these levels has structural and functional features with direct and critical implications onto national law enforcement curricula and training programs design, such as consistent revision of job competences, recognition of non-formal and informal learning and national accreditation and validation processes of qualifications and border police training programmes.

The deployment of sensors is the first issue encountered when microclimate monitoring is planned in spaces devoted to the conservation of artworks. Sometimes, the first decision regarding the position of sensors may not be suitable for characterising the microclimate close to climate-sensitive artworks or should be revised in light of new circumstances. This paper fits into this context by proposing a rational approach for a posteriori deployment of microclimate sensors in museums where long-term temperature and relative humidity observations were available (here, the Rosenborg Castle, Copenhagen, Denmark). Different statistical tools such as box-and-whisker plots, principal component analysis (PCA) and cluster analysis (CA) were used to identify microclimate patterns, i.e., similarities of indoor air conditions among rooms. Box-and-whisker plots allowed us to clearly identify one microclimate pattern in two adjoining rooms located in the basement. Multivariate methods (PCA and CA) enabled us to identify further microclimate patterns by grouping not only adjoining rooms but also rooms located on different floors. Based on these outcomes, new configurations about the deployment of sensors were proposed aimed at avoiding redundant sensors and collecting microclimate observations in other sensitive locations of this museum.

Due to deindustrialisation, young industrial landscapes (YILs), stemming roughly from the 1930s to the 1970s and located in the suburbs of Copenhagen, are partly abandoned, partly in use, and partly used for non-industrial purposes. By virtue of their location, size, and unused and underused subareas, YILs can potentially meet major urbanisation aims, such as densification and mixed-use development, yet the redevelopment of YILs often happens from a hypothetical virgin land position, disregarding the existing features of these sites. In this paper, we aim to introduce value-sustaining strategies for a more site-informed transformation of YILs. The specific objective is to investigate and understand the landscape-based transformation of young industrial landscapes by making explicit use of their site features in what we label the landscape. Based on a literature study of the emerging phenomenon, a screening of landscape-based projects and a case study, we present a set of qualifying strategies to guide future landscape-based transformations: porosity, reuse, re-naturing, and open-endedness. The complimentary spatial, multi-scalar, and temporal strategies were demonstrated through the study of the five European cases: Alter Flugplatz Kalbach, Hersted Industripark, IBA Emscher Park, Louvre Lens Museum Park, and Parc aux Angéliques, to exemplify how the strategies could guide the landscape-based transformation of YILs or similar types of large-scale landscapes. Although apparently straight forward, the formulation of the four strategies linking ethics and transformation practices provides a much needed set of values and tools in the current, and also historical, redevelopment of YILs, which are a significant part of our urbanised landscapes, to better address societal challenges.

Age-friendly cities and communities are currently attracting much attention as the ageing population becomes a larger proportion of our societies and their needs and aspirations become more diverse, which needs to be reflected in our cities. This calls for older people to play an active role in the design of suitable environments, e.g., by being involved in the design process. With this paper, we present a study where the methodology of co-design was used to engage 100+ older people in a low-income neighborhood in Copenhagen in designing new neighborhood spaces to reflect their needs and wishes. By focusing on the co-design process, and not the design solution, we investigate and present insights across the entire span of the process—from recruitment to implementation—and seek to extract particular elements that contribute to the age friendliness of the process. Recommendations for future co-design processes with older people include focusing on explicit communication and foreseeable steps to create a process that offers multiple and flexible participation options and to upgrade the latter stages of the co-design process through scale 1:1 prototyping and implementation. The findings contribute to both the professional practice of co-designing with older people on a spatial scale, as well as to policy makers and practice stakeholders when initiating initiatives with age-friendly cities and communities.

The atomic absorption and emission process that uses noninstantaneous electronic transitions of the atomic electron (i.e., electric charge), the tangent reference system, the property of speed instantaneity, and the conservation laws leads to a violation of Heisenberg’s uncertainty principle, and it is maintained in the atomic absorption and emission process discontinuity that is conserved as the emitted photon’s (i.e., electromagnetic radiation’s) discontinuity. This leads to a falsification of Bohr’s complementary principle that aligns with Einstein’s 1909 falsification of it. The violation of Heisenberg’s uncertainty principle and falsification of Bohr’s complementarity principle falsify the Copenhagen interpretation, because it requires Heisenberg’s uncertainty principle not to be violated and Bohr’s complementarity principle not to be falsified.

The number of outlaw bikers is growing globally. Despite this, little research exists on these groups and their alleged violent tendencies. To address this, the current paper uses unique data to examine whether gang violence causes outlaw biker violence. The period examined runs from mid-2008 until early 2012 during which violent clashes occurred between outlaw bikers and street gang members involved in an alleged conflict in Copenhagen, Denmark. A precise description of each individual act of violence would make it possible to identify whether specific acts were carried out in furtherance of the alleged conflict. This would allow one to determine whether outlaw bikers commit violence on behalf of their club. However, such knowledge is unavailable. The paper therefore takes a different approach by examining whether acts of violence committed by the two groups are statistically associated. In other words, it considers whether one or more acts can be described as retaliatory during the observation periods. The sample consists of 640 individuals involved with the Hells Angels Motorcycle Club or with non-biker street gangs–both of which are present in Copenhagen. Statistical models are used to predict 143 violent events committed by 196 outlaw bikers. The results suggest that violence committed by gang members predicts violence committed by outlaw bikers. This indicates that violent acts committed by outlaw bikers are at least partly a form of retaliation carried out on behalf of their club. The paper expands the literature on the kinds of inter-group, micro-level processes that can lead to reciprocal violence by including outlaw bikers in a literature that has previously focused on non-biker street gangs.

Housing expenses have the highest share in household budgets of low-income groups in Copenhagen leading to affordability problems. To provide affordable housing (AH) for low-income groups, the municipality developed a zoning plan in 2015 aimed to reserve up to 25% of land for new AH production. This qualitative case study compares the affordability of homes produced by private sector and nonprofit housing associations for low-income young groups at the risk of poverty and families in North and South Harbor areas of Copenhagen. Also, this paper explores local housing partnership agreements since 2009 and zoning plan developments in Copenhagen since 2015. Findings present the role of local governments in shaping socio-economic structure and partnership agreements that led to the development of AH by land use zoning in Copenhagen. In North Harbor, there were no AH units for families and young groups until 2020 when they were produced according to this zoning plan. The discussion presents the AH development in the higher property value harbor areas as a small but promising solution and a leading example for other Scandinavian countries. [ABSTRACT FROM AUTHOR]

An introduction is presented in which editors discusses various articles within the issue on topics including urban character gradually emerged in Odense, Denmark, excavations combined with Bayesian modeling of new radiocarbon dates in Copenhagen, Denmark.

The article provides an overview of the papers from the 2002 workshop on Vision and Modelling of Dynamic Scenes, held in conjunction with the European conference on computer vision in Copenhagen, Denmark. The papers were reviewed by a committee of international researchers. Nine papers were selected out of 25 submissions. Four of the papers were notable for their combination of theoretical advances and practical demonstrations.

Background: Results from previous studies suggest that bodily movements, spanning from gestures to whole-body movements, integrated into academic lessons may benefit academic learning. However, only few studies have investigated the effects of movement integrated into reading practice. The PLAYMORE study aims to investigate the effects of two interventions focusing on a close and meaningful coupling between bodily movement and academic content on early pre-reading and word recognition skills in children. Further, the study aims to compare two interventions involving either hand movements (i.e. using arms and hands) or whole-body movements (i.e. using the whole body). Potential mediating factors underlying the link between bodily movement on early pre-reading and word recognition skills will be explored.Methods/design: The PLAYMORE study will be conducted as a three-armed randomized controlled trial including children aged five to six years recruited from four schools in the Copenhagen area, Denmark. Stratified by class, children will be randomly allocated to one of three 8-week intervention/control periods: 1) teaching involving whole-body movements, 2) teaching involving hand movements (i.e. arms and hands) or 3) teaching involving minimal motor movements (i.e. seated on a chair using paper and pencil). Outcome measurements, including pre-reading and word recognition skills, will be collected before and after the intervention period to assess the intervention effects. This study protocol follows the SPIRIT guidelines.Discussion: The PLAYMORE study will add to the current knowledge concerning the link between bodily movement and academic performance with important details about pre-reading and word recognition skills in preschool children. If effective, evaluation of the implementation of the PLAYMORE program should be conducted in order to investigate whether the effects can be transferred into standard school settings. The PLAYMORE study will lay the foundation for future research that have the potential to inform the political and scientific debate and importantly, to provide teachers with detailed information of how to implement movements effectively during teaching in order to support and motivate children in the process of learning to read.Trial Registration: The study was retrospectively registered in ClinicalTrials.gov ( NCT04618822 ) the 5th of November 2020.

Since the rule of law was introduced into the EU enlargement policy, its role within the conditionality policy has advanced gradually so that it has become the cornerstone of the accession process. This paper analyses the evolution of the rule of law promotion in the process of EU enlargement with a focus on the Western Balkans and strives to identify what the main challenges are in this regard and the main reasons why the EU has made the rule of law central to its new enlargement methodology. Drawing on the experience of the Europeanisation process of the CEE countries, the paper examines the different approaches in terms of the promotion of the rule of law within the Copenhagen political accession criteria. It finds that with regard to the accession process of the Western Balkans, the EU is no longer satisfied with 'reforms on paper' and strives to apply more active leverage. However, the internal challenges for the rule of law within the EU and the often 'neglected' fourth Copenhagen criterion - absorption capacity of the Union itself referring to its capability to include new members - also affect the process. Rule of law conditionality has been compromised not only by more focus on the box-ticking benchmark fulfilment exercise than on substance, but also by the lack of credibility on the side of the EU that has undermined the pre-accession conditionality. The most illustrative case in this regard is the accession process of North Macedonia that is analysed as a case study in order to identify the main challenges and shortcomings of the EU enlargement policy. The paper proposes that the rule of law promotion and the overall Europeanisation process must rest on a credible merit-based accession process that involves clear commitments on both sides - candidate countries but also the EU.

Large-scale heat pumps (HPs) and refrigeration plants are essential technologies to decarbonise the heating and cooling sector. District heating and cooling (DHC) can be supplied with low carbon footprint, if power generated from renewable energy sources is used. The simultaneous supply of DHC is often not considered in energy planning, nor the characteristics of the heat source and sink. Simplified approaches may not reveal the true potential of HPs and chillers. In this paper, different heat sources and sinks and their characteristics were considered for the simultaneous supply of DHC based on large-scale HPs and refrigeration plants. An optimization model was developed based on mixed-integer linear programming. The model is able to identify ideal production and storage capacities, heat sources and sinks based on realistic hourly operation profiles. By doing so, it is possible to identify the most economical or sustainable supply of DHC using electricity. The optimization model was applied to the Nordhavn area, a new development district of Copenhagen, Denmark. The results show that a combination of different heat sources and sinks is ideal for the case study. A HP that uses the district cooling network as a heat source to supply DHC was shown to be very efficient and economical. Groundwater and sewage water HPs were proposed for an economical supply of district heating. The Pareto frontier showed that a large reduction in annual CO2 emissions is possible for a relatively small increase in investments. [ABSTRACT FROM AUTHOR]

In the past years, food has found itself a central focus of creativity in contemporary culture and a pinnacle of this trend has been the kind of culinary creativity displayed at Noma in Copenhagen. But what is culinary creativity? And what is distinctive about the kind of culinary creativity displayed at places like Noma? In this paper, I attempt to answer these two questions. Building up on pioneering work on creativity by Margaret Boden, I argue that creativity is a matter of adding new valuable things to the world. I then distinguish three different ways a recipe can be creative, building up on different culinary trends. I then focus on the specific case of Noma and argue that what is specific about the kind of culinary creativity displayed at Noma is that it emphasizes the role that recipes can play in mediating our relation to the environment.

Digital technology is becoming increasingly popular in dentistry. The aim of this article is to demonstrate and compare the capabilities of two different digital approaches, namely, intraoral scanning and digital examination of occlusion, in the final analysis of occlusion after orthodontic treatment. The capabilities and limitations of both systems are emphasized to help clinicians determine which system to use in specific cases. Materials and methods: The study included 32 patients (15 males and 17 females) in the retention phase after orthodontic treatment. Patients were aged 15 to 28 years with a mean age of 18.62 years (±4.17), and 62.2% were aged under 18 years. At the beginning of the orthodontic treatment, 18 patients had Angle Class I and 14 had Angle Class II. Overall, 18 patients were treated without extractions and 14 with extractions, while 12 had impacted teeth. All patients wore an Essix retainer in the upper jaw and a fixed canine-to-canine retainer in the lower jaw. Intraoral scanning was performed using Trios color (3Shape, Copenhagen, Denmark, 2014), and digital occlusion imaging was performed using T-Scan Novus (Tekscan, Norwood, MA, USA, 2018). SPSS 23.0 was used to perform descriptive statistical analysis. Result and Conclusion: With the 3Shape system, the contacts are marked based on the proximity between dentitions. The T-Scan system measures the strength of the contacts, regardless of their area. Despite its many advantages, intraoral scanning is not a reliable method for recording occlusions. The results obtained are not incorrect, but they include limited parameters for analysis. The T-Scan system provides comprehensive results and allows analysis and treatment of occlusal dysfunctions. The T-Scan system can provide information on the first contact, strength of the contacts, contact distribution on each tooth, sequence of contacts, maximum bite force and maximum intercuspation, path of the lower jaw movement, and occlusion and disocclusion times as well as record videos with active sequences and distributions of the contacts. There is a good collaboration between intraoral scanning and digital occlusion determination. [ABSTRACT FROM AUTHOR]

Background: Autism spectrum disorder (ASD) and schizotypal disorder (SD) both have a heterogenous presentation, with significant overlaps in symptoms and behaviour. Due to elevated recognition and knowledge of ASD worldwide, there is a growing rate of referrals from primary health professionals to specialised units. At all levels of assessment, the differential diagnostic considerations between ASD and SD exert major challenges for clinicians. Although several validated screening questionnaires exist for ASD and SD, none have differential diagnostic properties. Accordingly, in this study, we aim to develop a new screening questionnaire, the schiZotypy Autism Questionnaire (ZAQ), which provides a combined screening for both conditions, while also indicating the relative likelihood of each. Methods: We aim to test 200 autistic patients and 100 schizotypy patients recruited from specialised psychiatric clinics and 200 controls from the general population (Phase 1). The results from ZAQ will be compared to the clinical diagnoses from interdisciplinary teams at specialised psychiatric clinics. After this initial testing phase, the ZAQ will be validated in an independent sample (Phase 2). Conclusions: The aim of the study is to investigate the discriminative properties (ASD vs. SD), diagnostic accuracy, and validity of the schiZotypy Autism Questionnaire (ZAQ).

August Colding was one of the three pioneers who in the mid-1800s almost simultaneously and independently formulated the first law of thermodynamics, the two others being Robert Mayer and James Joule. This first, significant achievement was followed by a sequence of other ground-breaking discoveries within a broad range of disciplines: magnetism, steam power, gas production, hydraulics, soil physics, hydrology, heating and ventilation, meteorology, and oceanography. Moreover, he made a significant contribution to the understanding of the spread of cholera. In hydrology, he used evaporation experiments to obtain water balances. Independently, he formulated Darcy's law and was the first to calculate the water table between drainpipes and the piezometric surface in confined aquifers. His main occupation, however, was chief engineer in Copenhagen, where he modernized the city by introducing groundwater-based water supply and building a waterworks delivering pressured, clean water into houses, a gasworks and gas-based street lighting, and a citywide sewage system. Colding has not been as recognized internationally as he might deserve, probably because most of his publications were written in Danish. Even in Denmark, he seems today almost forgotten. This paper highlights his most important scientific contributions, in particular his achievements in hydrology, hydraulics, meteorology, and oceanography. [ABSTRACT FROM AUTHOR]

Study Question: Is there a difference in testicular function in early adulthood between men born with cryptorchidism and men born with normally descended testes?Summary Answer: In men from the general population, a history of cryptorchidism was associated with lower total testis volume and impaired semen quality as well as altered serum levels of reproductive hormones.What Is Known Already: The association between cryptorchidism and testicular function is well documented in studies based on sub-fertile or infertile men recruited from a clinical setting. However, the association has not previously been investigated in men from the general population, who were unselected regarding fertility status.Study Design, Size, Duration: This is a cross-sectional population-based study of 6376 young Danish men examined from 1996 to 2017.Participants/materials, Setting, Methods: This study is based on young men from the greater Copenhagen area, Denmark (median age of 19 years) who were unselected regarding fertility status and semen quality. The young men delivered a semen sample, had a blood sample drawn and underwent a physical examination including assessment of testis volume. Participants completed a questionnaire regarding cryptorchidism at birth, current lifestyle and their mother's pregnancy, after consulting their mother. The differences in markers of testicular function, including testis volume, semen parameters and reproductive hormones between men with and without a history of cryptorchidism were investigated with multiple linear regression analyses.Main Results and the Role Of Chance: The participation rate was 24% for the entire study period. Overall, a history of cryptorchidism was associated with reduced testicular function. In the adjusted models, a history of cryptorchidism was associated with a 3.5 ml lower total testis volume, determined by orchidometer (P < 0.001), 28% lower sperm concentration (95% CI: -37 to -20) and 26% lower inhibin B/FSH ratio (95% CI: -50 to -22) compared to men without a history of cryptorchidism, suggesting a reduced spermatogenetic capacity. Men with a history of cryptorchidism also had a slightly reduced Leydig cell function expressed as a 6% lower testosterone/LH ratio (95% CI: -12 to -0.7). The significant effect sizes and different markers of testicular function pointing in the same direction across the different models based on a large sample size support that the results are not chance findings.Limitations, Reasons For Caution: Information on cryptorchidism at birth and treatment modus was obtained by retrospective self-report, and each participant only delivered one semen sample.Wider Implications Of the Findings: The results suggest that men with a history of cryptorchidism could be at increased risk of experiencing fertility problems. However, among these men there is a wide variation in semen quality and further research is needed in order to identify the subgroup of boys born with cryptorchidism who are at the greatest risk of impaired semen quality when reaching adulthood.Study Funding/competing Interest(s): The study received financial support from the Research fund of Rigshospitalet, Copenhagen University Hospital; the European Union (Contract numbers BMH4-CT96-0314, QLK4-CT-1999-01422, QLK4-CT-2002-00603.

This paper addresses the challenge of minimizing training time for the control of Heating, Ventilation, and Air-conditioning (HVAC) systems with online Reinforcement Learning (RL). This is done by developing a novel approach to Multi-Agent Reinforcement Learning (MARL) to HVAC systems. In this paper, the environment formed by the HVAC system is formulated as a Markov Game (MG) in a general sum setting. The MARL algorithm is designed in a decentralized structure, where only relevant states are shared between agents, and actions are shared in a sequence, which are sensible from a system's point of view. The simulation environment is a domestic house located in Denmark and designed to resemble an average house. The heat source in the house is an air-to-water heat pump, and the HVAC system is an Underfloor Heating system (UFH). The house is subjected to weather changes from a data set collected in Copenhagen in 2006, spanning the entire year except for June, July, and August, where heat is not required. It is shown that: (1) When comparing Single Agent Reinforcement Learning (SARL) and MARL, training time can be reduced by 70% for a four temperature-zone UFH system, (2) the agent can learn and generalize over seasons, (3) the cost of heating can be reduced by 19% or the equivalent to 750 kWh of electric energy per year for an average Danish domestic house compared to a traditional control method, and (4) oscillations in the room temperature can be reduced by 40% when comparing the RL control methods with a traditional control method.

In the wake of the 2022 Nobel Prize in Physics, this paper recounts the fundamental milestones related to some problems in the foundations of Quantum Physics. After a brief historical journey, the superposition of states, the random character of measurements, quantum encryption and entanglement and the phenomenon of quantum teleportation are discussed. The meaning of the Einstein-Podolski-Rosen paradox and Bell's theorem are also analyzed. Some of the experiments carried out by the 2022 laureates aimed at analyzing the fulfillment or violation of Bell's inequality and the resolution of the conflict between local hidden variables theory and Quantum Physics are described. Finally, some of the most relevant interpretations of Quantum Physics are discussed, such as those of multiple universes, Bohn's mechanics and, of course, the Copenhagen interpretation.

Various material properties are involved in the success of endodontically treated restorations. At present, restorative composites are commonly employed as core build-up materials. This study aimed to systematically review the literature to assess the effect of using composite core materials on the in vitro fracture of endodontically treated teeth. Two different reviewers screened the literature, up to June 2021, in five distinct electronic databases: PubMed (MedLine), Scopus, Scielo, ISI Web of Science, and EMBASE. Only in vitro studies reporting the effect of the use of composite core materials on the fracture resistance of endodontically treated teeth were included. A meta-analysis was carried out using a software program (Review Manager v5.4.1; The Cochrane Collaboration, Copenhagen, Denmark). The risk of bias in each study was assessed following the parameters of another systematic review. A total of 5016 relevant papers were retrieved from all databases. After assessing the title and abstract, five publications remained for qualitative analysis. From these, only three studies remained for meta-analysis. The fracture strength of endodontically treated teeth where a core build-up composite was used was statistically significantly higher than the control (p = 0.04). Most of the analyses showed a high heterogenicity. The in vitro evidence suggests that the composite core build-up with higher filler content tended to improve the fracture resistance of the endodontically treated teeth, in comparison with conventional composite resins. This research received no external funding. Considering that this systematic review was only carried out on in vitro papers, registration was not performed. Furthermore, there were no identified clinical studies assessing core build-up materials; therefore, more well-designed research on these materials is needed. [ABSTRACT FROM AUTHOR]

The article reports on the 8th SCOS conference, which is being held between June 26-28, 1991, and it is being organized by the Copenhagen Business School in Copenhagen, Denmark. Some of the themes that will be focused on at the conference, include examining paradoxical situations using the concept of culture, mapping organizational culture, and the management of ambiguity, and culture across organizational contexts and boundaries. It is also reported that the deadline for submitting papers for the conference is March 1, 1991.

On February 6, 2016 at 21:07:19 UT, a very bright fireball was seen over the eastern part of Denmark. The weather was cloudy over eastern Denmark, but many people saw the sky light up—even in the heavily illuminated Copenhagen. Two hundred and thirty three reports of the associated sound and light phenomena were received by the Danish fireball network. We have formed a consortium to describe the meteorite and the circumstances of the fall and the results are presented in this paper. The first fragment of the meteorite was found the day after the fall, and in the following weeks, a total of 11 fragments with a total weight of 8982 g were found. The meteorite is an unbrecciated, weakly shocked (S2), ordinary H chondrite of petrologic type 5/6 (Bouvier et al. 2017). The concentration of the cosmogenic radionuclides suggests that the preatmospheric radius was rather small ~20 cm. The cosmic ray exposure age of Ejby (83 ± 11 Ma) is the highest of an H chondrite and the second highest age for an ordinary chondrite. Using the preatmospheric orbit of the Ejby meteoroid (Spurny et al. 2017) locations of the recovered fragments, and wind data from the date of the fall, we have modeled the dark flight (below 18 km) of the fragments. The recovery location of the largest fragment can only be explained if aerodynamic effects during the dark flight phase are included. The recovery location of all other fragments are consistent with the dark flight modeling. [ABSTRACT FROM AUTHOR]

Most interpretations of Quantum Mechanics alternative to Copenhagen interpretation try to avoid the dualistic flavor of the latter. One of the basic goals of the former is to avoid the ad hoc introduction of observers and observations as an inevitable presupposition of physics. Non-Copenhagen interpretations usually trust in decoherence as a necessary mechanism to obtain a well-defined, observer-free transition from a unitary quantum description of the universe to classicality. Even though decoherence does not solve the problem of the definite outcomes, it helps to explain why we do not observe superpositions and, according to Zurek's existential interpretation, why a specific preferred basis emerges through system–environment interactions. The aim of this paper is to show why such interpretation ends up begging the question and provides little progress in understanding the quantum-to-classical transition; the ultimate reason being that preferred bases always correlate to human observation. Benefitting from the technical discussion, some remarks will be offered in the last section regarding the role of classical observations as a necessary condition to make workable the formalism of Quantum Mechanics and scientific activity itself.

Data sourcesMedline, Cochrane Library, Embase, Science Citation Index and the China National Knowledge Infrastructure were used to source articles. In addition, identified papers' reference lists and their authors' other published literature were also scanned.Study selectionStudies of interest were randomised controlled trials of primary molar teeth where there was exposure of vital pulp caused by caries or trauma, with at least 6 months follow-up. It was required that selected teeth had no internal root resorption, inter-radicular and periapical bone destruction, no periodontal involvement, swelling, or sinus tract; they should be restorable with stainless steel crowns; and that outcomes were evaluated by clinical symptoms and radiographic evidence where the comparison followed a standard definition of success or failure, as shown by the number of teeth.Data extraction and synthesisData were extracted from each study independently and entered into a database. Differences were resolved by discussion. Studies were scored for validity criteria according to the Jadad scale. Meta-analysis was performed using the software RevMan (version 4.2.8; Copenhagen; The Nordic Cochrane Centre, The Cochrane Collaboration, 2003). Heterogeneity between studies was assessed using a standard chi-square test. If there was homogeneity among the studies, the fixed-effect model (Peto method) was applied to aggregate the data. If homogeneity was rejected then sensitivity analyses were performed using a random-effects model.ResultsSix studies met the inclusion criteria (giving a total of 381 teeth). There was a significant difference between the success rates of formocresol (FC)- and mineral trioxide aggregate (MTA)-treated pulpotomised primary molars (P<0.05) Clinical assessments and radiographic findings of the MTA versus FC pulpotomy suggested that MTA was superior to FC in pulpotomy, resulting in a lower failure rate [relative risk, 0.32 (95% confidence interval, 0.11–0.90) and 0.31 (95% confidence interval, 0.13–0.74) respectively].Conclusions The results demonstrate that in primary molar teeth with vital pulp exposure caused by caries or trauma, a pulpotomy performed with MTA results in better clinically and radiographically observed outcomes. Fewer undesirable responses were recorded for MTA than when FC was used. Therefore, the study supports the use of MTA instead of FC as wound dressing when performing pulpotomies on primary molars.Evidence-Based Dentistry (2007) 8, 11–12. doi:10.1038/sj.ebd.6400464 [ABSTRACT FROM AUTHOR]

A focus on indoor comfort and tightening targets for energy savings in buildings presents new opportunities for heating, ventilation, and air-conditioning products (HVAC). This paper presents a novel comfort solution that integrates a suspended radiant ceiling with diffuse ventilation, dubbed HVACeiling. In combination with the concrete slab, the HVACeiling has the potential to provide thermal comfort with minimal temperature offset, which supports operation of the heating and cooling system at temperatures very close to the room comfort temperature. The paper presents a parametric numerical study of the concept in a simplified two-pipe layout with fixed flow and fixed temperatures. First, the analysis was focused on different internal and solar loads, heat losses, and climatic locations with the aim of assessing the potential of self-regulation, i.e., no active controls, thermal comfort, ability to reduce peak loads and the consequential building design considerations. Secondly, the purpose was to analyse the concept in a generic office building with five offices and one meeting room and compare it to other HVAC solutions. The whole-year analyses of heating, cooling, energy performance, and thermal comfort were done using the building performance simulation software IDA ICE. It was found that it was possible to create thermal comfort in Paris, Munich, and Copenhagen with water circulating constantly with fixed temperatures of 20–24 °C without controls and with window sizes from 15 to 30% of the floor area. The studies showed that the HVACeiling reduced the operative peak temperatures on the warmest days in comparison with a standard radiant ceiling with mixing ventilation by 1 K. Compared to all-air solutions, the HVACeiling reduced the yearly energy consumption by 20–30% and the peak power in summer up to 69%. This study indicates that thermal comfort is achievable in a European context even at very small temperature offsets, which supports the use of more renewable energy sources. [ABSTRACT FROM AUTHOR]

Efforts to digitally engage with indigenous source communities and craftspeople are many and diverse. This paper has as its starting point a comparison between two such digital engagements, both celebrations of Arctic animal fur clothing, yet each at seemingly opposite ends of a continuum of possible digital interfaces. Skinddragter Online and Mittimatalik Arnait Miqsuqtuit Collective were both launched the same year, 2015, in Copenhagen and Mittimatalik, Nunavut, Canada respectively. By comparing each with the other, our ambition is to illuminate some of the curatorial choices involved in the making of such digital platforms, and the consequences they have in terms of wider visibility, audiences reached, knowledge included, and collaborative engagements invited. Postcolonial critique can come at the expense of general outreach, conversations between designated experts can be difficult to make equal. Technological sophistication can be challenged by the digital divide. Attention to issues of cultural appropriation is a constant. Yet, driving these initiatives is the need to maintain a digital diversity in online and offline spaces. [ABSTRACT FROM AUTHOR]
