The metaverse has emerged as an exciting new paradigm for human-computer interaction (HCI) and virtual collaboration. This paper presents a comprehensive review of the metaverse to address the gap in the existing literature where there is a lack of a survey that reviews the nature of the metaverse and its building blocks from a human-centric perspective. We first synthesize a definition of the metaverse from existing literature and delineate key affordances. We then introduce a detailed framework encompassing the metaverse's nature, infrastructure technologies, and input/output technologies that facilitate multi-sensory HCI, alongside applications across diverse domains. The components within this framework are explained in depth, offering insights into the metaverse's nature and the readiness level of current technologies. Based on this comprehensive analysis, we outline major open challenges and propose promising directions demanding further exploration and investigation. By clarifying the vision for the metaverse and characterizing the building blocks required to realize it, this review provides essential insights and serves as an invaluable resource for metaverse developers and researchers working to advance this transformative new medium.

Large language models (LLMs) are artificial intelligence tools that have the prospect of profoundly changing how we practice all aspects of medicine. Considering the incredible potential of LLMs in medicine and the interest of many health care stakeholders for implementation into routine practice, it is therefore essential that clinicians be aware of the basic risks associated with the use of these models. Namely, a significant risk associated with the use of LLMs is their potential to create hallucinations. Hallucinations (false information) generated by LLMs arise from a multitude of causes, including both factors related to the training dataset as well as their auto-regressive nature. The implications for clinical practice range from the generation of inaccurate diagnostic and therapeutic information to the reinforcement of flawed diagnostic reasoning pathways, as well as a lack of reliability if not used properly. To reduce this risk, we developed a general technical framework for approaching LLMs in general clinical practice, as well as for implementation on a larger institutional scale., (©Dimitri Roustan, François Bastardot.

Successful performance in sport is a multifactorial process that includes a blend of technical, tactical, physiological, biomechanical, and psychological features interacting together to result in the desired performance outcome. The strength and conditioning (S&C) program, depending on the sport, can support performance by influencing the physiological and biomechanical components through direct and indirect avenues of impact. Performance planning to achieve identified objectives is typically a long-term process, ranging from a year in seasonal professional team sports to a four-year Olympic cycle. It is critical to develop and implement key strategic processes to ensure that the S&C program effectively supports performance at major competitions. Furthermore, it is essential to have clarity for the role of S&C within the overall sports training program. Having a clear approach to deconstructing and understanding performance from a human performance perspective, showing how and where the impact on performance can be made, and objectively demonstrating the contribution to performance variables is vital. The current article uses the author's experience of working across a range of Olympic and professional sports to articulate a process for strategic planning and managing S&C support from a technical perspective. Examples from various sports have been used to illustrate critical strategic processes. [ABSTRACT FROM AUTHOR]

Rowing performance across 2,000m is determined by a multitude of physiological factors and the ability to execute the rowing stroke with technical efficiency. The primary determinants of performance are power at maximal oxygen consumption (2), peak power output, and power at 2 & 4 mmol/L of blood lactate. The current paper aims to deconstruct rowing performance to develop an S&C technical framework and establish the key avenues for impact or objectives. This may be critical for decision-making regarding programming by outlining the bio-motor qualities contributing to performance. The technical framework was developed via an in-depth needs analysis conducted by reviewing the existing body of literature within rowing, the author's knowledge of underpinning sciences (i.e., physiology, biomechanics, and functional anatomy), and collaboration with the multi-disciplinary team (i.e., the technical coach and physiotherapist). The established objectives for S&C support were: 1) contributing towards maximizing peak power output; 2) supporting the development of stroke efficiency; and 3) contributing towards the reduction of injury occurrence as well as increasing the tolerance towards overall training load. It was identified that bio-motor qualities such as maximal force expression (Fmax) and rate of force development (RFD) and an appropriate range of movement and tissue tolerance developed through the S&C program may interact together to achieve these objectives. The targeted bio-motor qualities were developed through training methods such as heavy and explosive strength training and work capacity training. Phase potentiation was used, with Fmax and tissue tolerance developed in the general preparation phase, before an RFD focus in the specific preparation and competition phases. [ABSTRACT FROM AUTHOR]

Canoe slalom requires technical ability, well-developed energetics, a high level of maximum force production, and range of movement to perform a variety of complex paddle stokes, while maneuvering through a challenging whitewater course. The strength and conditioning (S&C) coach should provide strategic direction across a network or department including S&C coaches working toward identified outcomes and measures. S&C coaches should collaborate with a multidisciplinary support team (i.e. sport coaches, physiotherapists, physiologists, etc.) to develop a technical framework. The technical framework may allow for development of training strategies that provide a clear breakdown of the outcomes, adaptations, exercises, and testing methods. The current article articulates this process related to a canoe slalom national performance program. [ABSTRACT FROM AUTHOR]

Highlights • Presenting a framework to assess connecting PV plants to weak distribution systems. • Determining required technical analyses to perform when connecting large PV plants. • Predicting impacts of PV plants at design stage and finding improvement techniques. • Validating the developed proposal for multiple real-world PV integration projects. Abstract Weak power distribution systems are those that are highly sensitive to fluctuations in voltage magnitude and/or frequency. Due to the intrinsic intermittency and inertia-less nature of photovoltaic systems, the connection of a utility-scale photovoltaic plant to a weak distribution system can lead to grid instability or even collapse. This paper presents a structured framework for performing grid connection studies to evaluate the integration of photovoltaic plants into weak distribution systems. The two main characteristics of weak distribution systems (i.e., low-inertia and high-impedance connection points) are handled separately since each factor has distinct issues, risks and mitigation methods. Also, some systems may only exhibit weakness in one of these aspects, but not the other. Recommendations are provided in the paper for the appropriate studies to be performed and the features to be investigated for the development of utility-scale photovoltaic plants connected to weak distribution systems.

Simulation has been widely used as a tool for training, especially in high risk areas such as in the aerospace, military and medical fi elds. Surgery is one of the sub areas that has been receiving much attention from researchers due to the ability of simulation to provide a real surgery setting and human organs with appropriate devices to increase the realism. Developing a surgical simulation is a technically complex process since it involves a few components that interact with each other. Thus this necessitates further considerations regarding the issues and challenges in order to produce an accurate and interactive application. Therefore there is a need for a technical solution framework to help a new and novice researcher in this area to get started. This paper discusses the important components of a surgical simulator, together with its issues and challenges. A proposed solution framework, together with the programming or application choices that are available for each of the components, is explained clearly as concluded from the discussion in the previous work. The class structure for the components is shown briefl y to give the new researcher an idea of it. It is hoped that this paper will serve as a foundation for new and novice researchers in haptic development specifi cally and visual informatics generally.

In isotope Cs tracing studies, it is a premise to determine suitable Cs reference inventory (CRI) plots and the CRI values. Owing to the heterogeneous spatial distribution of Cs deposition in the ground and diverse, or even irregular, operations in sampling and testing procedures, CRI determination is usually faced with many difficulties and uncertainties. In addition, more difficulties occur in an investigation of a large-scale region because of time constraints and measurement cost limitations. In this study, traditional CRI acquiring methods were summarized first, and then a new complex scheme was established, involving seven core steps and coupling the model estimate and sample measurement. The above CRI determination methodology was implemented in the central-eastern Inner Mongolia Plateau. The case study results showed that the CRI in the dark chestnut soil sub-region, located in the east and south of Xing'an City, exhibited 2447 Bq·m; the CRI in the aeolian sandy soil sub-region, positioned in the south central Tongliao City and central Chifeng City, showed 2430 Bq·m; the CRI in the sandy chernozem soil sub-region, situated in the northwestern Chifeng City, presented 2384 Bq·m; and the CRI in the chestnut soil sub-region, in the southern Xilin Gol City, was 2368 Bq·m. The newly proposed CRI determination scheme was proved effective, and the determined CRI plots and CRI values were convincing. The methodology offered a framework for Cs tracing studies in large-scale regions or long-distance transects. [ABSTRACT FROM AUTHOR]

In this paper, we analyse how contextualised media can be used to support learning. Additionally, the advantages of contextualised learning and the types of learning that are fit to be supported are discussed. Our focus throughout the paper will be on lifelong learning, and the integration of formal and informal learning therein. However, we think, to this date, most of the research concerning contextualised and mobile learning has been focusing on technological issues. Therefore, as an attempt to shift the discussion to a more educational perspective, a generic technical framework is presented. The technical framework is based on a reference model that came about as the result of a literature analysis in a previous paper. The reference model should provide a foundation that leads to a flexible and generic technical framework that can be used in a range of different learning scenarios. Moreover, a generic technical approach should aim at an easier integration of contextualised learning appliances into current learning. [ABSTRACT FROM AUTHOR]

Abstract: Clean production is studied from thermodynamic perspectives. Based on comparative analyses of industrial processes and thermodynamic systems, mechanisms of clean production are thermodynamically revealed and a guiding theoretical framework for clean production is correspondingly proposed. The framework not only provides a theoretical foundation for clean production technologies, but also offers a possible quantitative way for the operation and assessment of clean production.

This paper reviews the recent history of the Information Assurance (IA) movement and examines the Information Assurance Technical Framework (IATF) proposed by the United States Government's National Information Assurance Partnership (NIAP) in the height of the potential terrorist attacks on the cyberspace that draw no geographical or temporal boundaries. Under the heightened alert, all organizations scramble to plug the security holes of their information infrastructure to assure safe end user access to the mission-critical information. This paper argues that the focus of IATF is based on the enforcement of a top-down information infrastructure without specifying the impact to the end users or "information consumers." Furthermore, a complete IA defensive strategy built on a Defence-in-Depth Strategy dictates only what people executing operations through the use of technology can achieve. The IATF addresses the technology portion of this strategy to defend against five classes of attacks: Passive, Active, Insider, Close-in, and Distribution. This is accomplished through four overlapping approaches and layers of protection, referred to collectively as Defence-in-Depth technology areas. The paper concludes by highlighting the implications and impact of the IATF and related issues to all citizens in the end user community, particularly the possible gains and sacrifices that end users are facing, particularly the key issue of assurance of information ownership.

• Closing the gap between needs of urban water infrastructure and IoT capabilities • Defining required temporal and spatial resolutions for network-based applications • Identifying suitable communication technologies for different resolutions • A guideline for the realisation of smart water cities is presented Smart cities are an innovate concept for managing urban cities to enhance sustainability and increase quality of life for citizens. Although urban water infrastructure (UWI) performs important functions in a city (e.g., supply of drinking water), information and communication technologies (ICT) and system-wide management of network-based UWI are not yet widely deployed. Therefore, this review summarises first both existing and potential applications related to network-based UWI, characterised by different spatial and temporal resolution of measurement and control data. Second, a comprehensive analysis of ICT is provided, which is extended with exemplary applications in the field. The analysis reveals that a coordination between intended application and usable communication technology is required to realise an efficient monitoring and control network in the field of UWI networks. To overcome this limitation, a detailed framework is developed, which can be used by researcher, network operators, and stakeholder to identify suitable communication technologies for different UWI applications or to determine possible applications for an existing ICT system. Following, the applicability of the framework is demonstrated by selected examples. As the framework also indicates, an integrated approach towards smart water cities requires the combination of different communication technologies to satisfy all specifications.
