The paper highlights how significant characteristics of liver can be modeled in tissue-engineered constructs using unconventional scaffolds. Hepatic lobular organization and metabolic zonation can be mimicked with decellularized plant structures with vasculature resembling a native-hepatic lobule vascular arrangement or silk blend scaffolds meticulously designed for guided cellular arrangement as hepatic patches or metabolic activities. The functionality of hepatocytes can be enhanced and maintained for long periods in naturally fibrous structures paving way for bioartificial liver development. The phase I enzymatic activity in hepatic models can be raised exploiting the microfibrillar structure of paper to allow cellular stacking creating hypoxic conditions to induce in vivo-like xenobiotic metabolism. Lastly, the paper introduces amalgamation of carbon-based nanomaterials into existing scaffolds in liver tissue engineering. Plain Language Summary Unconventional scaffolds have the potential to meet the current challenges in liver tissue engineering- loss of hepatic morphology and functions over long-term culture, absence of native-like cell-cell and cell-matrix interactions, organization of hepatocytes into lobular structures exhibiting metabolic variations-which hinder pharmaceutical analysis, regenerative therapies and artificial organ development. Paper with cellulose microfibril network develops cellular aggregates with hypoxic conditions that influence enzymes of xenobiotic metabolism proving to be a better scaffold for hepatotoxicity testing compared with conventional monolayers in tissue culture plates. Decellularized plant stems provide already-built vasculature to be exploited for the development of intricate vessel networks that exist in hepatic lobules aiding in regenerative medicine for hepatic pathologies. Fibrous plant structures are excellent materials for the immobilization of hepatocytes and improve albumin secretion enabling their use in bioartificial liver development. Biomimicry of metabolic zonation in hepatic lobules can be achieved with perfusion culture using silk blend scaffolds with varying proportions of the liver matrix that orchestrate cellular function. The mechanical properties of silk allow the fabrication of structures that resemble liver anatomy to generate native-like hepatic lobules. Nanomaterials have immense potential as a component of composite material development for scaffolds to achieve improved predictive ability in pharmacokinetics. Most of these unconventional scaffolds have the added advantage of being readily available, accessible, affordable and sustainable for liver tissue engineering applications. Conclusively, the shift of attention away from conventional scaffolds poses a promising future in the field of tissue engineering. Graphical Abstract Article highlights Limitations of 2D culture: Current 2D culture practices cannot achieve the complexity of hepatic tissue including metabolic zonation, lobular organization, extensive vasculature, existence of multiple cell types. Splenic scaffold: Spleen proves to be the excellent choice of decellularized organ for liver tissue regeneration, however, this cross-organ recellularization procedure is not ideal for clinical translation. Plant-based scaffold: Selecting plant material that matches hepatic tissue mechanical properties and anatomical features including the channel arrangements (central vein and portal triad) help hepatic regeneration and pathological modeling. Naturally fibrous plant materials have the potential to be excellent platforms for bioartificial liver development based on high hepatocyte adherence and function. Paper-based scaffold: Hepatocyte culture on functionalized filter paper forms a physiologically more relevant model for hepatotoxicity assessment particularly because of higher activity of drug metabolizing enzymes. Silk-based scaffold: Hepatic lobular organization that supports metabolic zonation can be mimicked by varying ECM content in silk blend scaffolds to create native-like oxygen and nutrient gradient. CNT-based scaffold: Exceptional properties of carbon nanotubes make them ideal to mimic liver ECM allowing formation of hepatic spheroids with in vivo like characteristics- bile canaliculi, polarity and drug clearance.

The Continental Congress foray into printed money during the American Revolution was so disastrous that the United States printed no more money for nearly a century, the one exception being a brief period during the War of 1812. After that Congress chartered and unchartered its national bank twice. The American economy henceforth (1816–1836) was often structurally short of coins, and without any national coinage Americans had to find substitute forms of currency to finance the burgeoning economy. The Supreme Court ruled that sovereign States and individuals could authorize both State and private banks to issue their own notes. In consequence, nearly all paper money in circulation was either State or private banknotes based on a limited reserve of gold. This generally proved insufficient to adequately fund major infrastructure projects. The federal government also had no institution for raising or transferring large amounts of money to fund these national improvements. Nonetheless, Hamilton's U.S. Bank, without the help of a national currency, was an institutional precursor for what would not take final form until 1913. There would be no Federal Reserve today without the Whig-Republican agenda institutionally incarnated in the First and Second U.S. Bank. [ABSTRACT FROM AUTHOR]

In cotton yarn bundles and fabric layers, wicking and rate are accounted as crucial indigenous liquid transportation properties, playing a significant role in temperature reduction on their surfaces and being used to extend the food and agricultural storage life. In this article, manual test methods are described to measure water wickability and wicking rate of cotton yarn bundles and plain weave fabric layers. These methods described the water flow through the in-plane surface of yarn bundles and fabric layers oriented in either vertical or horizontal lines without external force. The wicking lengths and wicking growth rates in both untreated and treated cotton yarn bundles and fabric samples in either in-plane vertical or horizontal orientations were compared. The highest to lowest wicking length and rate were found in the treated yarn bundles, treated fabric layers, untreated yarn bundles, and untreated fabric strips, respectively. The wicking height and length obtained in untreated yarn bundles and untreated fabric layers was lower than the Kraft paper. The higher wicking and rate values indicate a considerable potential for liquid water migration. The results indicated that treated yarn bundles and fabric layers that are oriented horizontal direction are the best options for constructing capillary evaporative cooling. [ABSTRACT FROM AUTHOR]

Residential owned solar panels mounted on roof-tops generated 1.4% of the U.S. electricity supply in 2022. Utilities compensate residential customers using a net metering system by which each kilowatt-hour generated by the customer reduces the customer's bill by the amount the utility charges for one kilowatt. Despite the small impact of roof-top solar on the total market, in 2022, thirty-two states conducted ninety-four proceedings investigating whether to change the net metering system. In these proceedings, utilities advocated changing the rates to discourage residential investment in solar panels. Utilities argue that net metering provides a subsidy to solar customers because the rate the utility pays is greater than the avoided cost of energy. That excess payment allows solar customers to avoid paying for the distribution network. The cost of the distribution network is shifted to non-solar customers. This article will evaluate these claims. It will show that if the social cost of carbon were in the calculation, it would generate a Kapp cost shift from solar customers to non-solar customers. The size of the Kapp cost shift is greater than the cost of distribution networks, reversing any private cost shift that utilities have estimated. [ABSTRACT FROM AUTHOR]

Quantitative geographical methods have played an important role in COVID-19 research. To complement and extend previous review studies, we conduct a scoping review of COVID-19 studies employing quantitative geographical approaches by focusing on 331 papers published in 45 journals in geography, urban studies, and planning. We identify four major research themes (clusters): (1) how SARS-CoV-2 viruses spread in cities, (2) the COVID-19 mortality (death) rates and their association with socioeconomic variables, (3) how the COVID-19 pandemic changed people's mobilities, and (4) how the COVID-19 pandemic affects air pollution. We conclude that spatial models play a key role in COVID-19 quantitative geographical approaches, and human mobility is an important and widely studied topic. We also reveal a lack of research focusing on environmental pollution (other than air pollution) that potentially worsened during the pandemic. [ABSTRACT FROM AUTHOR]

This article sets out the findings of a systematic review on research into career guidance policy in the Nordic countries between 2008 and 2022. In total 60 papers were reviewed from across the Nordic region. They focused on national career guidance systems, career guidance systems for young people, the adult guidance system and career guidance for migrants. The corpus proved to be methodologically diverse with studies utilizing a wide range of different research strategies, although important differences were found between academic and grey literature. Most of the papers reviewed were atheoretical, with the remaining, mainly academic, literature drawing heavily on critical theory. The thematic analysis identified four major themes in the corpus: the context for career guidance policy; career guidance provision and practice; technologies of governance; and beneficiaries and outcomes of career guidance policies. The findings are discussed in relation to the strengths and weakness of the corpus and used to propose a research programme for the next 15 years. [ABSTRACT FROM AUTHOR]

"Big Bend National Park: Mexico, the United States, and a Borderland Ecosystem" by Michael Welsh is a historical exploration of Big Bend National Park, situated on the border between Mexico and the United States. The book examines the unique landscape of the park, shaped by the Rio Grande river, and the challenges posed by its borderland ecosystem. Welsh discusses the efforts of conservationists, politicians, and scientists in establishing the park and highlights the potential for binational cooperation and collaboration. The book also addresses the tensions between preservation and development in national parks and the need to navigate the changing cultural and political landscape. While the book lacks an examination of the park's future in the face of climate change and public policy, it offers valuable insights for students and scholars interested in national identity, border relations, and environmental protectionism.

The Ultra-Wideband (UWB) Location-Based Service is receiving more and more attention due to its high ranging accuracy and good time resolution. However, the None-Line-of-Sight (NLOS) propagation may reduce the ranging accuracy for UWB localization system in indoor environment. So it is important to identify LOS and NLOS propagations before taking proper measures to improve the UWB localization accuracy. In this paper, a deep learning-based UWB NLOS/LOS classification algorithm called FCN-Attention is proposed. The proposed FCN-Attention algorithm utilizes a Fully Convolution Network (FCN) for improving feature extraction ability and a self-attention mechanism for enhancing feature description from the data to improve the classification accuracy. The proposed algorithm is evaluated using an open-source dataset, a local collected dataset and a mixed dataset created from these two datasets. The experiment result shows that the proposed FCN-Attention algorithm achieves classification accuracy of 88.24% on the open-source dataset, 100% on the local collected dataset and 92.01% on the mixed dataset, which is better than the results from other evaluated NLOS/LOS classification algorithms in most scenarios in this paper.

With the maturity of information and communication technology (ICT), numerous innovative applications are proposed in different arenas including smart living environments. Technology-enabled smart living has transformed the traditional living system to an enhanced user satisfaction model by providing a balanced environment, thus, securing the residents from disruptions and risks. Besides these magnified advantages, it is found almost full of faints in emergency situations. The researchers and architects put their full potential towards the development of new applications, but no significant attention is paid to analyze the existing designs to identify flaws and suggest enhanced solutions accordingly. To bridge this gap in the literature, this paper presents a comprehensive review to evaluate the capabilities of available smart home designs to counter any emergency situations. Along with highlighting safety, healthcare, and many other unwanted challenges, we also discussed the key problems that obfuscate the trustworthiness of smart homes for its residents. Moreover, the design limitations to present an early alarming and automatic evacuation mechanism especially for deaf, blind, and other visually impaired people is another big challenge to tackle. Finally, we elaborate on the limitations of available smart home solutions and suggest various open research problems that require further development. [ABSTRACT FROM AUTHOR]

The market of courier, express and parcel services (CEP) is characterized by the presence of requests for the transfer of goods and documents. During the COVID-19 pandemic, the global postal and CEP infrastructure played a key role in enabling governments to respond to the emerging challenges. In this paper, the competitiveness and the rank of four observed CEP service providers are analyzed using ratio indicators, the Ordinal Priority Approach method (OPA) and the Weighted Sum Method (WSM). We use the OPA method because there is no need for a pairwise comparison matrix and no need for normalization. The paper aims to examine the liquidity, economy and profitability of CEP service providers to get a true picture of the situation in the market of postal and CEP services in the Serbia. In the analysis of business performance and the implementation of the OPA method, the opinions of experts were taken into account. This paper yields a key insight: the identification of the top-performing provider within the group of service providers is accomplished through the utilization of both the OPA and WSM methods. Sensitivity analysis is shedding light on the varying impact of the provider's rank on the final ranking of the CEP providers. [ABSTRACT FROM AUTHOR]

Nowadays, an increasing number of crises worldwide, triggered by climate extremes, natural and human-made hazards, the coronavirus pandemic, and more, pose a high pressure on crisis, emergency, and disaster management. Spatial data and Volunteered Geographic Information (VGI) are key issues in the successful and immediate response to crises. This paper aims to explore the use of VGI in crisis management, including emergency and disaster management, based on a scoping review of existing literature in English for five years (2016–2020). Specifically, the research intends to answer Scoping Review Questions (SRQ) regarding the use of VGI in crisis, emergency, and disaster management, and the verified cases' spatial distribution, the VGI sources utilized (e.g. OpenStreetMap – OSM, Crowdsourcing, Twitter), the types of hazards (e.g. natural and human-made hazards, pandemic), the specific tasks in crisis, emergency or disaster management and VGI use in the management of actual crisis events, e.g. COVID-19 pandemic, Hurricane Katrina, etc. Eligible papers on VGI use in crisis, emergency, and disaster management are geolocated based on first-author affiliation, and as a result, a spatial bibliography is provided. Thus, the term Spatial Scoping Review is introduced. Scoping Review Questions are answered, and the results are analyzed and discussed. Finally, implementing the "VGICED Atlas", a web atlas, permits the publication of the research results to a broad audience and the visualization of the analysis with several interactive maps.

Pakistan has suffered from pervasive corruption since its foundation. It deals with an unstable political atmosphere and unsustainable economic development due to its fragile institutional setting. The predominance of military power that does not hesitate to overrule any government when it faces a potential threat to its economic-profit channels plays an important role in institutional fragility. Moreover, incompetent civilian rules and the British heritage comprise a vicious cycle that is hard to break. An anemic institutional environment struggles within an embedded cultural structure exacerbated by corruption. This paper discusses corruption in Pakistan from historical, institutional, and economic standpoints. It provides a historical background of corruption. Then, it analyzes the negative economic reverberations of the corruption phenomenon. As an institutional case study, the paper concentrates on National Accountability Bureau (NAB), suggesting that institutional quality can be accomplished through bureaucratic accountability and determination, not through political victimization and abuse of institutions.

Rock discontinuity information plays a key role in engineering activities. In severely fragmented and discontinuous samples, the identification accuracy of rock discontinuities can be improved with the help of geologic knowledge with identified spatial features and geoscience interaction mechanisms. Therefore, we proposed a new method – a knowledge-based intelligent recognition method for rock discontinuities that used point cloud data – to correct inaccurate identification by considering the spatial relationships of rock discontinuities. This paper integrated the geologic knowledge bases in rock discontinuity information extraction rules and combined the generative rule inference model with the region growing method for intelligent extraction. In the case study, we developed four typical rule sets as examples based on the constructed rule system to group rock discontinuities and subsume the fractured rock discontinuities. Results show that this new method is effective in identifying and classifying rock discontinuities of complex areas with a greater reduction in manual intervention. [ABSTRACT FROM AUTHOR]

For the estimation of global karst carbon sink, a few conventional methods usually require the parameters that are difficult to measure, resulting in the big cost. Moreover, under the constraints of incomplete and timeliness issues in the collection of data over a large region, it has remained a challenge for these methods to study global karst carbon sink. Therefore, this paper proposes estimating the global karst carbon sink, and analyzing the suitability of the response surface methodology and the fluctuating variation of karst carbon sink in global karst regions from 1951 to 2050. This paper shows that the proposed method can reduce the time of numerical calculation and is suitable for application in global weathering models; The global karst carbon sink in the future changes not only displays an upward trend but also exposures its fluctuating trend largely. This fluctuation is probably due to global warming. [ABSTRACT FROM AUTHOR]

Poverty has always been a global concern that has restricted human development. The first goal (SDG 1) of the United Nations Sustainable Development Goals (SDGs) is to eliminate all forms of poverty all over the world. The establishment of a scientific and effective localized SDG 1 evaluation and monitoring method is the key to achieving SDG 1. This paper proposes SDG 1 China district and county-level localization evaluation method based on multi-source remote sensing data for the United Nations Sustainable Development Framework. The temporal and spatial distribution characteristics of China's poverty areas and their SDG 1 evaluation values in 2012, 2014, 2016, and 2018 have been analyzed. Based on the SDGs global indicator framework, this paper first constructed SDG 1 China's district and county localization indicator system and then extracted multidimensional feature factors from nighttime light images, land cover data, and digital elevation model data. Secondly, we establish SDG 1 China's localized partial least squares estimation model and SDG 1 China's localized machine learning estimation model. Finally, we analyze and verify the spatiotemporal distribution characteristics of China's poverty areas and counties and their SDG 1 evaluation values. The results show that SDG 1 China's district and county localization indicator system proposed in this study and SDG 1 China's localized partial least squares estimation model can better reflect the poverty level of China's districts and counties. The estimated model R2 is 0.65, which can identify 72.77% of China's national poverty counties. From 2012 to 2018, the spatial distribution pattern of SDG evaluation values in China's districts and counties is that the SDG evaluation values gradually increase from western China to eastern China. In addition, the average SDG 1 evaluation value of China's districts and counties increased by 23% from 2012 to 2018. This paper is oriented to the United Nations SDGs framework, explores the SDG 1 localized evaluation method of China's districts and counties based on multisource remote sensing data, and provides a scientific and rapid regional poverty monitoring and evaluation program for the implementation of the 2030 agenda poverty alleviation goals.

The launch of large language models (LLMs) like ChatGPT in late 2022 and the anticipated arrival of future GPT-x iterations have marked the beginning of the generative artificial intelligence (GAI) era. We conducted a systematic review of how to integrate LLMs including GPT and other GAI models into geospatial science, based on 293 papers obtained from four databases of academic publications -- Web of Science (WoS), Scopus, SSRN and arXiv -- 26 papers were eventually included for analysis. We statistically outlined the share of domains where LLMs and other GAI models, the type of data that have been used for these models, and the modelling tasks and roles that they play. We also pointed out the challenges and future directions for the next research agenda -- along with which we could better position ourselves in the mainstream of science and the cutting-edge research paradigm as others leverage insights from the growing data deluge.

Aim: This paper investigates the conditions for inclusive design of regenerative medicine interventions from a bioethical perspective, taking regenerative valve implants as a showcase. Methods: A value hierarchy is construed to translate the value of justice into norms and design requirements for inclusive design of regenerative valve implants. Results: Three norms are proposed and translated into design requirements: regenerative valve implants should be designed to promote equal opportunity to good health for all potential users; equal respect for all potential users should be shown; and the implants should be designed to be accessible to everyone in need. Conclusion: The norms and design requirements help to design regenerative valve implants that are appropriate, respectful and available for everyone in need. Plain Language Summary Scientists in the field of regenerative medicine are developing a new type of heart valve implant. After implantation, the synthetic implant slowly breaks down and is replaced by a new living heart valve. These so-called regenerative implants promise a complete cure. However, they also raise ethical questions. For example, questions related to justice and inclusion. In this paper, we explore how regenerative implants can be designed to be inclusive, meaning suitable, respectful and available for everyone. We argue that the design of regenerative implants should be adapted to relevant differences between users. The implants should be affordable in the short and long term. The implants should be suitable for use worldwide. The implants should be designed by teams of diverse age, gender and ethnicity. Users should be engaged in the design. And the communication about the implants to researchers and users should be inclusive. Overall, this paper provides ethical guidance to researchers and clinicians developing regenerative implants. Article highlights Health research and care should be inclusive to address inequities in health. Inclusion also deserves attention within the rapidly evolving field of regenerative medicine. However, what inclusion means and what inclusive design should entail in the context of regenerative medicine is not clear. This paper investigates the conditions for inclusive design of regenerative medicine interventions, taking regenerative valve implants (i.e., in situ tissue-engineered heart valves) as a showcase. The aim of inclusive design relates to the value of justice. Justice is concerned with recognition (claims about equal respect for marginalized groups and undervalued social identities) and redistribution (the equitable distribution of goods and resources). A values hierarchy is a deliberative tool to translate a value into norms and design requirements in the context of technology design. The value of justice can be translated into three norms: regenerative valve implants should be designed to promote equal opportunity to good health for all potential users; in the design process, equal respect for all potential users should be shown; and the implants should be designed to be accessible to everyone in need. Based on these norms, the following design requirements can be formulated: regenerative valve implants should be designed to account for relevant user differences, be affordable and cost-effective and be suitable for global distribution, and the design process should involve diverse design teams, engage users and use inclusive communication. Together, the norms and design requirements shape the conditions for inclusive design of regenerative valve implants. This paper aids the design of implants that are appropriate, respectful and available for everyone in need. More generally, by exemplifying an ethically proactive approach to the design of regenerative medicine technology, it contributes to responsible development of regenerative medicine interventions.

Generally, Cryptococcus initially infects the respiratory tract, but can spread, eventually crossing the blood-brain barrier (BBB) and causing meningitis or meningoencephalitis. Specifically, Cryptococcus invades the vascular endothelial cells of the BBB, from which it enters the brain. The main mechanisms through which Cryptococcus crosses the BBB are transcellular traversal, the paracellular pathway, and via Trojan horse. In this paper, the mechanisms by which Cryptococcus crosses the BBB were explained in detail. In addition to pathways of entry to the brain, this paper presents a discussion on some rare cryptococcal infections and provides some insights for future research directions. [ABSTRACT FROM AUTHOR]

Developing a school as a learning community is a complex process necessitating active engagement from the entire school community. This paper reports on a study from Finland that focused on exploring learning community development grounded in a shared vision. We sought to investigate the development of a school community with a separate primary and lower secondary school as it progressed towards becoming a unified comprehensive school. The research involved close school-university collaboration to support the community's transformative journey. Our particular interest in this paper is the relationship between the shared vision and learning community development. At the conclusion of the development project, seven semi-structured interviews were conducted with members of the school management team. Thematic analysis of the interview data was undertaken to identify their perceptions of how the shared vision was linked to learning community development. The in-depth analysis revealed five major themes: (1) communication of the shared vision and transparency; (2) present and absent themes in the shared vision; (3) tradition and innovation; (4) the long-term nature of school development; and (5) the role of the vision in everyday school life. The analysis drew attention to how a school's past and present influence a shared vision and school development. This study provides insights into how the preconditions of a school community contribute to the implementation of a shared vision as a catalyst for change. Recognising the distinct needs and starting points of schools is crucial, emphasising the importance of understanding the pre-existing context in school development. [ABSTRACT FROM AUTHOR]

This paper describes a 2-stage tactic for achieving an odd-order variable-bandwidth (OO-VBW) filter with absolutely guaranteed stability. The design methodology aims to minimize the p-norm amplitude-response error while maintaining the OO-VBW-filter's stability. In order to tune OO-VBW filter's amplitude response, we utilize a kind of functions of the bandwidth (BW)-tuning parameter to express the filter's coefficients. Because those functions have changeable function values, the designed OO-VBW-filter's amplitude response possesses variability. Another important concern in this paper is the stability issue. When the filter coefficient values expressed as function values are changed, the OO-VBW filter that has feedback structures may become unstable. This necessitates that the OO-VBW-filter's stability must always be preserved during real-time tuning. In order to stabilize such an OO-VBW filter that has feedback structures, a coefficient-conversion (CC) algorithm is adopted, and it is incorporated into the 2-stage methodology for obtaining the OO-VBW filter. To illustrate both the stability and high approximation accuracy, the design of an OO-VBW bandpass filter is simulated. The simulation details verify that both stability and high accuracy can be successfully achieved. [ABSTRACT FROM AUTHOR]

This paper examines the relocation experiences of sixteen women and men who moved with their children to Aotearoa New Zealand when their partners took up career positions in that country. It analyses the relative weight they gave to their careers and their relationships with their partners as they responded to the challenges posed by these transitions. Attention to the interests of children is also identified as significant in their career decisions. Interviews with similar numbers of women and men whose partners were globally mobile employees enables analysis of the diverse ways in which gender shapes career pathways during a period of transition. The findings contribute to a complex analysis of the situation of those previously referred as a 'trailing' or 'accompanying' spouse when a dual career couple engages in international relocation.

Co-designed health initiatives are gaining popularity in Aotearoa (New Zealand). However, emerging research identifies potential pitfalls for Indigenous populations, particularly Māori (Indigenous Peoples of Aotearoa), when Kaupapa Māori principles are ignored. Using the Indigenous He Pikinga Waiora Implementation (HPW) framework as a guide, this paper provides an autoethnographic reflective account of the co-design process that led to the development and implementation of the Whirihia holistic assessment tool for the Kaupapa Māori antenatal wānanga (workshop) Whirihia Te Korowai Aroha. The co-design process resulted in a culturally appropriate and responsive holistic assessment tool that provided a quality health needs assessment pathway for māmā hapū (pregnant women) and their whānau (family). This reflective account provides examples of key considerations that align to the HPW framework in the hope that it will afford some guidance for fellow emerging researchers who wish to undertake ethical co-designed health research with Māori (and non-Māori) communities and organisations.

Road traffic crashes are becoming thorny issues being faced worldwide. Traffic crashes are spatiotemporal events and the research on the spatiotemporal patterns and variation trends of traffic crashes has been carried out. However, the impact of built environment on traffic crash spatiotemporal trends has not received much attention. Moreover, the spatial non-stationarity between the variation trends of traffic crashes and their influencing factors is usually neglected. To make up for the lack of analysis of built environment factors influencing spatiotemporal hotspot trends in traffic crashes, this paper proposed a method of "ST-GWLR" for analyzing the influence of built environment factors on spatiotemporal hotspot trends of traffic crashes by combining the spatiotemporal hotspot trend analysis and Geographically Weighted Logistic Regression (GWLR) modeling methods. Firstly, the traffic crash spatiotemporal hotspot trends were explored using the space-time cube model, hotspot analysis, and Mann-Kendall trend test. Then, the GWLR was introduced to capture the spatial non-stationarity neglected by the classic Global Logistic Regression (GLR) model, to improve the accuracy of the model estimation. GWLR model is used for the first time to analyze the significant local correlation between the traffic crash spatiotemporal hotspot trends and the built environment factors, to accurately and effectively identify the built environment factors that have significant influences on the hotspot trends of traffic crashes. The performance of the GWLR models and GLR models was examined and compared sufficiently. The results showed that the proposed ST-GWLR, which captured spatial non-stationarity, performed better than the classic GLR combined with spatiotemporal analysis, and improved the prediction accuracy of the models by 14.9%, 13.9%, and 15.1%, respectively. There were significant local correlations between intensifying hotspots and persistent hotspots of traffic crashes and the built environment factors. The findings of this paper have positive implications for traffic safety management and urban built environment planning. [ABSTRACT FROM AUTHOR]

With the development of remote sensing technology and computing science, remote sensing data present typical big data characteristics. The rapid development of remote sensing big data has brought a large number of data processing tasks, which bring huge challenges to computing. Distributed computing is the primary means to process remote sensing big data, and task scheduling plays a key role in this process. This study analyzes the characteristics of batch processing of remote sensing big data. This paper uses the Hungarian algorithm as a basis for proposing a novel strategy for task assignment optimization of remote sensing big data batch workflow, called optimal sequence dynamic assignment algorithm, which is applicable to heterogeneously distributed computing environments. This strategy has two core contents: the improved Hungarian algorithm model and the multi-level optimal assignment task queue mechanism. Moreover, the strategy solves the dependency, mismatch, and computational resource idleness problems in the optimal scheduling of remote sensing batch processing tasks. The proposed strategy likewise effectively improves data processing efficiency without increasing computer hardware resources and without optimizing the computational algorithm. We experimented with the aerosol optical depth retrieval algorithm workflow using this strategy. Compared with the processing before optimization, the makespan of the proposed method was shortened by at least 20%. Compared with popular scheduling algorithm, the proposed method has evident competitiveness in acceleration effect and large-scale task scheduling. [ABSTRACT FROM AUTHOR]

Visual Attention Prediction (VAP) is widely applied in GIS research, such as navigation task identification and driver assistance systems. Previous studies commonly took color information to detect the visual saliency of natural scene images. However, these studies rarely considered adaptively feature integration to different geospatial scenes in specific tasks. To better predict visual attention while driving tasks, in this paper, we firstly propose an Adaptive Feature Integration Fully Convolutional Network (AdaFI-FCN) using Scene-Adaptive Weights (SAW) to integrate RGB-D, motion and semantic features. The quantitative comparison results on the DR(eye)VE dataset show that the proposed framework achieved the best accuracy and robustness performance compared with state-of-the-art models (AUC-Judd = 0.971, CC = 0.767, KL = 1.046, SIM = 0.579). In addition, the experimental results of the ablation study demonstrated the positive effect of the SAW method on the prediction robustness in response to scene changes. The proposed model has the potential to benefit adaptive VAP research in universal geospatial scenes, such as AR-aided navigation, indoor navigation, and street-view image reading.

The scarcity of public resources and environmental pollution caused by rapid urbanization highlight the practical significance of parks in ensuring the sustainable development of a city. Therefore, the social equity of parks warrants further study. This paper proposes a fine-grained comprehensive evaluation framework that combines geographic accessibility models, geo-statistical analysis, and machine learning algorithms to explore social inequity in Taiyuan, China. In this framework, gini coefficient and lorentz curve express spatial equality, accessibility shows spatial equity, and ridge regression model handles the interdependence of variables with different dimensions to quantify the relative effects of local participants on changes in park accessibility. On this basis, the imbalance between vulnerable groups and park supply is analyzed to further understand the core concept of social equity. Results highlight serious spatial inequality in all three types of parks allocation of six urban areas, especially in community parks. The actual access level of people to parks is also stratified by their demographic and socioeconomic characteristics, revealing the social inequity in access to parks. Park distribution is indeed not conducive to some social vulnerable groups, whose contradiction between supply and demand is highly prominent in urban – rural junctions and new urban areas. This paper also confirms the unfair layout of public facilities can be observed in second-tier cities of China by highlighting the social inequity of parks in Taiyuan. The findings of this work have profound implications for urban planning and sustainable development. [ABSTRACT FROM AUTHOR]

The OECD is an inevitable force in contemporary education. This paper illustrates how the OECD affects recent education policy-making in Iceland with a particular focus on recent documents establishing the new Education Policy 2030 in Iceland and on OECD reports that directly relate to this policy. We illustrate the relationship between these documents both topically and chronologically and use Marilyn Strathern's (2006) reasoning about policy making by bullet-points to understand these policy products. Our conclusions are that education policy 2030 is a clear step into a more Nordic tradition of policymaking, in terms of basing policy in previous works and official reports as well as increasing involvement by stakeholders. However, they are characterized by politically admirable, albeit lofty, formulations of ambitions and focus areas, rather than measurable, actionable and implementable policies. The OECD is given a great influence not only as a referential point and a tool to legitimate particular policies, but also a post-hoc policy-implementation adviser and auditor of the policy. Even though the OECD is asked for evaluation of the visionary policy and seems to be the solution to the perceived lack of professional procedure in Icelandic governance, the time-frame seems not to have allowed a thorough use of their advice.

Internet-based psychological treatments for depression have been around for more than 20 years. There has been a continuous line of research with new research questions being asked and studies conducted. In this paper, the author reviews studies with a focus on papers published from 2020 and onwards based on a Medline and Scopus search. Internet-based cognitive behavior therapy (ICBT) programs have been developed and tested for adolescents, older adults, immigrant groups and to handle a societal crisis (e.g. COVID-19). ICBT works in regular clinical settings and long-term effects can be obtained. Studies on different treatment orientations and approaches such as acceptance commitment therapy, unified protocol, and tailored treatments have been conducted. Effects on quality-of-life measures, knowledge acquisition and ecological momentary assessment as a research tool have been reported. Factorial design trials and individual patient data meta-analysis are increasingly used in association with internet intervention research. Finally, prediction studies and recent advances in artificial intelligence are mentioned. Internet-delivered treatments are effective, in particular if therapist guidance is provided. More target groups have been covered but there are many remaining challenges including how new tools like artificial intelligence will be used when treating depression. [ABSTRACT FROM AUTHOR]

The multi-level modeling technology of Building Information Modeling (BIM), combined with Three-dimensional Geographic Information System (3DGIS) macro-scene visualization technology and location information, can realize the transmission of decentralized information from various disciplines to multi-disciplinary collaborative information sharing services. It can be applied independently for the whole life cycle, which plays a positive role in reducing the cost and improving the efficiency of engineering planning, design, construction, operation, and maintenance. In this paper, the data integration and function integration methods of 3DGIS and BIM are designed. In order to avoid the breaking problems caused by attribute information loss and excessive simplification in the process of BIM data integration, the attribute mapping between 3DGIS and BIM based on Industry Foundation Classes (IFC) and City Geography Markup Language (CityGML) and the data simplification method considering the geometric characteristics of BIM are designed. By setting the relevant preconditions and thresholds of patch merging, on the premise of maintaining the structural characteristics of BIM data surface, reduce the amount of model data to improve the efficiency of BIM data loading, rendering and display effect in 3D geospatial scene. Through the data and function integration of 3DGIS and BIM, we can effectively manage the data of large-scale model, and calculate and obtain the geospatial location and direction of key parts of buildings through the coordinate transformation of BIM, which can effectively assist the rapid and accurate positioning of BIM in virtual 3D scene and expand the visualization ability of 3DGIS. By effectively integrating 3DGIS and BIM, this paper gives full play to the spatial management advantages of 3DGIS and the component management advantages of BIM. The rationality and operability of the method are verified by its application in the operation and maintenance management project of concealed facilities in actual buildings. [ABSTRACT FROM AUTHOR]

This paper proposes a new testing method, phased array ultrasonic testing, for the internal defects of gear teeth, which can be used to inspect the teeth of final products, breaking the limitations of incomplete volume coverage of conventional ultrasonic testing. This paper mainly discusses the inspection process of phased array ultrasonic testing, and verifies the feasibility of phased array ultrasonic testing for gear teeth defects of finished products by using physical and chemical inspection technology. The practical application results show that the phased array ultrasonic testing technology uses sector scanning mode to scan the area comprehensively between the pitch circle and the base circle, and the inspection image displayed by the equipment is intuitive, which can clearly identify defects. The number of defects inspected by phased array ultrasonic testing is consistent with the results of the physical and chemical inspection technology. The above summary shows that phased array ultrasonic testing is feasible, and the test results are reliable. [ABSTRACT FROM AUTHOR]

This paper revisits a classical problem in linkage mechanism design, specifically the design of centric crank-rocker mechanisms for a specified rocker stroke with unit time ratio. Beyond the traditional objective of minimizing the transmission angle's deviation from 90 degrees, this paper uses another objective: maximizing the shortest-to-longest link-length ratio in the linkage. The former objective ensures motion transmission quality in the mechanism, while the latter aims to make the mechanism less sensitive to variations in link lengths. It is shown that these two objectives are inherently conflicting, necessitating a trade-off solution. To address this, a Pareto front is developed by analyzing the governing design equations. The front is further normalized by relating each objective to its limit value. A design example using the normalized front is provided that showcases different optimization options. The TOPSIS method is used to illustrate the selection of a preferred design alternative. [ABSTRACT FROM AUTHOR]

In recent times, there has been a growing focus on multi-micro-grids (MMGs) system, owing to its well-suited structures for efficiently accommodating large-scale integration of distributed energy resources (DER). This attention is driven by the system's cost-effectiveness, enhanced efficiency, stability, and reliability performance, achieved through the collaborative exchange of power flow among individual micro-grids (MGs) and the main grid. Fundamental strategies for attaining optimal energy flow and sharing involve the optimal sizing of MGs and the implementation of an Energy Management System (EMS). These strategies play a crucial role in addressing uncertainties associated with intermittent generation, load fluctuations and energy market dynamics. This paper offers a review of grid-connected MMG topologies, EMS structures, coordination methods and current optimization approaches designed to meet EMS objectives. To address the inherent volatilities, the paper introduces various uncertainty quantification techniques along with current challenges. Additionally, it suggests future directions, emphasizing intelligent and predictive modeling to handle uncertainties, as well as recommending the incorporation of energy storage systems (ESSs) to align with emerging trends.

In multi-antenna systems, advanced techniques such as massive multiple-input multiple-output (MIMO), beamforming, and beam selection depend heavily on the accurate acquisition of the channel state. However, pilot contamination (PC) can be a major source of interference which degrades they are performance. Moreover, the severity of PC increases as more pilots are reused between users in the wireless systems. Researchers have shown that PC can be mitigated by using deep learning (DL) approaches. Nevertheless, when minimizing PC, the examination that identifies the applications and factors that distinguish these DL approaches is still limited. This paper reviews these DL approaches and the improvements needed to enhance their performance. Simulation results confirm that DL networks that learn to predict the channels directly have superior performance under PC. [ABSTRACT FROM AUTHOR]

The study of yield gaps has become more complex, prompting the use of varied approaches to measure yields and a wider range of factors to explain these gaps. In the Global North, the focus is on precision farming, whereas in sub-Saharan Africa (SSA), a broader perspective is necessary due to pronounced variability in farmland conditions. While biogeophysical and management factors have been traditional focal points in yield gap analyses, socio-economic and institutional factors are increasingly recognized as significant, especially in SSA. This review synthesizes research from the past decade in SSA that integrates biogeophysical, management, farm characteristics, and institutional factors in yield gap discussions. The findings indicate a slow shift in including socio-economic factors, with management, particularly nutrient supply and crop management, remaining predominant. However, there is a growing trend towards methodological diversity, such as the adoption of remote sensing and GIS in recent years. Case studies from Kenya and Ghana, utilizing field surveys, interviews, panel data, and spatial analysis, highlight how a multifaceted approach can enhance our understanding of the various elements influencing maize yield gaps in SSA.

Vegetation segmentation via point cloud data can provide important information for urban planning and environmental protection. The point cloud dataset is obtained using light detection and ranging (LiDAR) or RGB-D images. Oblique photogrammetry has received little attention as another important source of point cloud data. We present a pointwise annotated oblique photogrammetry point-cloud dataset that contains rich RGB information, texture, and structural features. This dataset contains five regions of Bengbu, China, with more than twenty thousand samples in this paper. Obviously, previous indoor point cloud semantic segmentation models are no longer applicable to oblique photogrammetry point clouds. A random sampling point transformer (RSPT) network is proposed to enhance vegetation segmentation accuracy. The RSPT model offers both efficient and lightweight architecture. In RSPT, random point sampling is utilized to downsample point clouds, and a local feature aggregation module based on self-attention is designed to extract additional representation features. The network also incorporated residual and dense connections (ResiDense) to capture both local and comprehensive features. Compared to state-of-the-art models, RSPT achieves notable improvements. The intersection over union (IoU) metric increased from 96.0% to 96.5%, the F1-score increased from 90.8% to 97.0%, and the overall accuracy (OA) increased from 91.9% to 96.9%.

Urban rail transit (URT) systems play an evident role in shaping city spatial structures; however, the principles and mechanisms behind this influence are not fully understood. This paper reviews research progress on the coupling relationship between URT and urban space, focusing on big data analysis methods and the timeliness and sequence of coupling effects. It highlights the importance of the temporal dimension in coupling analysis. By thoroughly exploiting data value and extracting key elements, big data technology imparts temporal attributes to these elements, exploring their interaction and influence mechanisms over different time sequences. The paper also discusses the potential application of big data to urban planning to support sustainable urban development. Finally, the paper outlines future research directions, including the deepened application of big data to urban spatial analysis and the role of new data sources in understanding and shaping the coupling relationship between URT and urban space. This analysis offers new perspectives and methodologies for urban development and transportation planning. [ABSTRACT FROM AUTHOR]

Remote sensing image building segmentation, which is essential in land use and urban planning, is evolving with advancements in deep learning. Conventional methods using convolutional neural networks face limitations in integrating local and global information and establishing long-range dependencies, resulting in suboptimal segmentation in complex scenarios. This paper proposes LMSwin_PNet, a novel segmentation network that addresses the SwinTransformer encoder's deficiency in local information processing through a local feature extraction module. Additionally, it features a multiscale nonparametric merging attention module to enhance feature-channel correlations. The network also incorporates the pyramid large-kernel convolution module, replacing the traditional 3 x 3 convolution in the decoder with multibranch large-kernel convolution, thereby achieving a large receptive field and detailed information capture. Comparative analyses on three public building datasets demonstrated the model's superior segmentation performance and robustness. The results show that LMSwin_PNet produced outputs closely matching labels, showing its potential for broader application in remote sensing image segmentation tasks. It achieved achieving an IoU of 72.35% on the Massachusetts Building Dataset, 91.30% on the WHU Building Dataset, and 78.99% on the Inria aerial-image building dataset.

Delayed graft function (DGF) is an early complication after kidney transplantation. The literature on DGF has experienced substantial growth. However, there is a lack of bibliometric analysis of DGF. This study aimed to analyze the scientific outputs of DGF and explore its hotspots from 2013 to 2023 by using CiteSpace and VOSviewer. The 2058 pieces of literature collected in the Web of Science Core Collection (WOSCC) from 1 January 2013 to 31 December 2023 were visually analyzed in terms of the annual number of publications, authors, countries, journals, literature co-citations, and keyword clustering by using CiteSpace and VOSviewer. We found that the number of papers published in the past ten years showed a trend of first increasing and then decreasing; 2021 was the year with the most posts. The largest number of papers was published by the University of California System, and the largest number of papers was published by the United States. The top five keyword frequency rankings are: ‘delayed graft function’, ‘kidney transplantation’, ‘renal transplantation’, ‘survival’, and ‘recipients’. These emerging trends include ‘brain death donors’, ‘blood absence re-injection injuries’, ‘tacrolimus’, ‘older donors and recipients’, and ‘artificial intelligence and DGF’. In summary, this study reveals the authors and institutions that could be cooperated with and discusses the research hotspots in the past ten years. It provides a reference and direction for future research and application of DGF. [ABSTRACT FROM AUTHOR]

For an academic field to remain vital, it is necessary to reflect upon its conceptual foundations and learn from adjacent disciplines. On that note, aesthetics can provide significant insights into advertising. While aesthetic elements have received attention in advertising research, no systematic attempts have been made to provide a comprehensive overview of this literature. The purpose of this conceptual article is to bring different branches of aesthetic theory into advertising studies. Marketers have historically focused on product functionality and often appeal to consumers through explicit messages. This article fills an important gap by delineating and advocating the conceptual foundation of advertising aesthetics as a research area worthy of further attention. In short, we understand advertising aesthetics as the artlike properties of and sensory responses to ads. A review of 309 papers provides the thematic outline of the study. Seven key themes are identified: (1) the nature of advertising aesthetics, (2) advertising creativity, (3) textuality, (4) social aesthetics, (5) cross-cultural differences, (6) the role of media in creating aesthetic opportunities, and (7) aesthetic categories beyond the beautiful and sublime. These themes offer a novel way of exploring contemporary issues in advertising. The article concludes with suggestions for future research. [ABSTRACT FROM AUTHOR]
