Authors: Song Shijun , Yin Junhui , Liu Lei , Yang Zhaoshu , Han Chao , Xiong Chao 
Published: February 2024

AbstractThis article reports a carbon fiber–reinforced plastic Kagome composite honeycomb sandwich structure reinforced with polymethacrylimide (PMI) foam (PKCSS). Low‐velocity impact performances on the node, rib, and two cell centers of the PKCSS were experimentally compared with those on a composite Kagome honeycomb sandwich (CKHS), and the failure mechanism of the PKCSS was investigated. The impact process was analyzed through an explicit numerical analysis using ABAQUS. A three‐dimensional Hashin failure criterion was introduced using the VUMAT subroutine. Results confirmed that the PKCSS exhibits higher impact and specific loads than the CKHS, with the maximum improvements of 69.7% and 39.5%, respectively, under 50‐J impact energy. As an uncrushable material, the PMI foam provides strong impact resistance during its plateau stage. This technology of cell filling can be used to fabricate lightweight all‐composite honeycomb sandwiches for potential use in ultrahigh engineering applications.Highlights

Published: February 2024

AbstractExcessive ultraviolet (UV) radiation has serious damage to human's health, therefore the development of visible, portable, and wearable sensor for monitoring UV radiation, especially the cumulative UV dosage, is highly desired but full of challenges. Herein, a wearable and flexible UV dosimeter based on photochromic perovskite nanocrystals (PNCs) is designed. The obtained CsPbCl3 PNCs dispersed in dibromomethane (PNCs‐DBM) undergo continuous, vivid, and multiple (from very weak purple to blue, cyan, and finally strong green) color change in response to UV radiation. It is demonstrated that the UV‐induced degradation of DBM and subsequent anion‐exchange reaction between CsPbCl3 and Br−, play a crucial role in the color change of PNCs‐DBM. The properties of continuous fluorescence color change and enhanced fluorescence intensity enable the construction of sensitive and visible UV dosimeter. Furthermore, by integrated photochromic PNCs with flexible bracelet or PDMS substrate, a wearable UV sensor or a multi‐indicator array for the detection of solar UV dosage is developed. This work may advance the fundamental understanding about photochromic perovskite, and show promising application of perovskite nanomaterials in easily fabricated, low‐cost, visualized, and wearable solar UV dosimeter.
A survey on post‐quantum based approaches for edge computing security
Authors: Karakaya Aykut , Ulu Ahmet 
Published: February 2024

AbstractWith the development of technology and its integration with scientific realities, computer systems continue to evolve as infrastructure. One of the most important obstacles in front of quantum computers with high‐speed processing is that its existing systems cause security vulnerabilities. Therefore, in order to take advantage of quantum systems, existing systems that are already secure must also be secure in the post‐quantum scenario. One of these systems is edge computing. There are challenges in terms of computational power for the implementation of pre‐ and post‐quantum methods in structures with resource‐constrained devices. This article reviews the post‐quantum security threats of edge devices and systems and the secure methods developed for them. Although there is relatively little research in this field, it remains relevant. In the studies reviewed, lattice‐based approaches are often highlighted for making edge systems quantum‐resistant. Additionally, these studies indicate that there has been an increasing trend in this field in recent years.This article is categorized under:

Numerical and statistical analysis of unsteady hydromagnetic hybrid nanofluid flow in a porous medium over an inclined disk with dissipative heat transfer
Authors: Kar Ajay Kumar , Kumar Premful , Singh Ramayan , Nandkeolyar Raj 
Published: February 2024

AbstractThe present analysis deals with the three‐dimensional radiative, convective hybrid nanofluid flow over a rotating and stretching inclined disk under the action of the applied magnetic field, Joule's heating, and viscous dissipation effects. The mathematical model considers nanoparticles graphene oxide (GO) and molybdenum disulfide (MoS) suspended in water as the base fluid within a Darcy medium. The cylindrical coordinate system is used to express continuity, momentum, and energy partial differential equations, out of which momentum and energy partial differential equations are transformed into ordinary differential equations using a suitable transformation method under the boundary‐layer approximation. The transformed equations are further solved using the spectral quasi‐linearization method. Graphical and numerical data are presented to investigate the behavior of velocity and temperature under various parameters and shape factors. The nature of fluid flow at the boundary wall is determined by tables of skin friction and the Nusselt number. Statistical analysis of the parameters for axial and tangential skin friction and the Nusselt number is performed using the quadratic regression model.
The Unfolding Regulator–Regulatee Relationship
Authors: Le Coze Jean-Christophe 
Published: February 2024

AbstractThe regulator–regulatee relationship in the context of safety-critical systems is under constant evolution. It changes with epochs. Our current epoch is one faced with increasingly global challenges. It has not always been so, but increasingly is. In this introduction, the presentation of the chapters of this book is preceded by a historical perspective which situates the advent of many important regulatory innovations and trends (e.g., polycentric, smart, meta, or risk-based regulations). These innovations and trends are variously interpreted, from either practical, critical, or more neutral angles. This introduction explains the rationales of these different points of view. Next, an example of regulation of hazardous organisations in France is shortly described to illustrate the trends discussed. It provides a short empirical case study. The chapters of the book are then summarised, covering a diversity of related themes, from polycentric to responsive regulations, through an attention to social interactions to the game-changing reality of global warming.
Rule Design: Defining the Regulator–Regulatee Relationship
Authors: Coglianese Cary 
Published: February 2024

AbstractRules constitute a defining feature of the relationship between regulators and regulated entities. To succeed in fostering sound risk management for society, regulators need to choose carefully how they design their rules, taking into account both their own capacities and the capabilities of those that they regulate. This chapter describes a two-by-two framework for rule design based on means-end and micro-macro dimensions. By adopting and applying this framework, regulators can identify the relative advantages and disadvantages of different regulatory approaches and better inform decision-making about how to define the regulator–regulatee relationship.
The Healthcare Regulatory Ecosystem
Authors: Braithwaite Jeffrey 
Published: February 2024

AbstractHealthcare is a complex adaptive system, with considerable fragmentation between healthcare institutions and medical specialisations. The regulation of safety in healthcare involves both formal (legislation, accreditation procedures, policies, procedures) and informal (professional standards, ethical principles, accepted modes of care) components. These instruments are complemented by self-regulation by clinicians and by patients who invest in understanding their ailments and selecting desired treatment modes. In recent years, the Safety-II approach is increasingly recognised as an important regulatory paradigm.
Recognising the Social Nature of Regulatory Compliance and Focusing on Front-Line Interactions
Authors: Pautz Michelle C. 
Published: February 2024

AbstractIn the swirling conversations about regulation and compliance, a fundamental aspect is often neglected: the fact that regulatory compliance is inherently a social process. Regulation requires individuals (and their organisations) to alter their behaviour and subject themselves to some sort of review or monitoring of that behaviour. Further, actions and involvement with one another are required by individuals on the front-lines of regulation, the regulators, and the regulatees, and not just the individuals at the highest levels of governments and organisations. This chapter will review how regulatory compliance is fundamentally a social process that is engaged in by key—but often overlooked—front-line actors, describe these interactions, and detail the implications for regulatory governance moving forward.

Published: February 2024

ZusammenfassungWetterdienste und andere Forschungseinrichtungen in Deutschland und seinen Nachbarländern beobachten seit dem 19. Jahrhundert, wie sich das Klima in Mitteleuropa verändert. Auf Basis der gesammelten Beobachtungen lassen sich Aussagen über die Klimaentwicklung in Deutschland treffen: Die Daten erlauben Beschreibungen der Atmosphäre vom täglichen Wetter bis zur Klimaentwicklung über mehrere Jahrzehnte. Darüber hinaus liefern die Langzeitbeobachtungen auch Datensätze, welche die Überprüfung von Klimamodellen ermöglichen. Das Kapitel stellt schwerpunktmäßig die Geschichte der Beobachtungen sowie die tatsächlich gemessene Veränderung verschiedener Klimavariablen für Deutschland dar. Außerdem werden Nutzbarkeit und Einschränkungen der Datensätze für die Evaluation der Klimamodelle bewertet.
Minderungsstrategien im Personen- und Güterverkehr
Authors: Flämig Heike , Gertz Carsten , Mühlhausen Thorsten 
Published: February 2024

ZusammenfassungDie Verkehrssysteme haben einen wesentlichen Anteil am menschgemachten Klimawandel. Zugleich werden sie durch Extremwetterereignisse und Wetterphänomene selbst in ihrer Funktionsfähigkeit eingeschränkt. Es kann zu Engpässen bei der Versorgung kommen. Die bisherigen technischen und organisatorischen Maßnahmen zur Effizienzsteigerung konnten die absoluten induzierten negativen Klimaeffekte bislang nicht im notwendigen Umfang reduzieren. Daher bestehen große Erwartungen an Maßnahmen, die ein verkehrsreduzierendes Entscheidungsverhalten bei jedem Einzelnen und allen Organisationen und Unternehmen bedingen. Um dies zu beschleunigen, braucht es ein konsequentes Handeln zum Erreichen der Klimaschutzziele durch politisch-planerische Rahmensetzungen und ein vorausschauendes Agieren bei der Umsetzung von Anpassungsmaßnahmen.

Published: February 2024

ZusammenfassungDie schnelle und umfassende Emissionsminderung in der Energie- und Kreislaufwirtschaft ist der Schlüssel für die Begrenzung der Erderwärmung auf unter 2 °C. In Deutschland werden entsprechende Politiken seit den 1990er-Jahren verfolgt, allerdings erst in jüngster Vergangenheit mit dem notwendigen Nachdruck und der notwendigen Orientierung hin zu mehr Marktmechanismen. Wesentliche Handlungsfelder sind Energieeinsparung und erhöhte Energieeffizienz, Umstieg auf erneuerbare Energien, Bepreisung von Klimagasen sowie eine Reduzierung und Schließung der Stoffkreisläufe. In allen Handlungsfeldern sind Grundlagen geschaffen, es bleibt jedoch der Großteil des Weges noch zu gehen, um Klimaneutralität zu erreichen. Für einen schnellen Fortschritt spielen neben der Überwindung der technischen, ökonomischen und organisatorischen Herausforderungen auch Verteilungsfragen und die Einbettung in internationale Maßnahmen eine zunehmende Rolle.
The Legacy of Radical Exclusion in Cities
Authors: Pineda Victor Santiago 
Published: February 2024

AbstractThe cities we live in today continue to be largely inaccessible, unaffordable, and restrictive, leading to the intentional and unintentional exclusion of marginalized groups. This is the result of decisions made by various entities that influence the design of cities and create a sense of either exclusion or belonging. The lack of accessibility in the built environment perpetuates inequity and marginalizes difference, such as the exclusion of people with disabilities in employment due to inaccessible workplaces. The notion of exclusion was entrenched by the “ugly laws” in the Progressive Era, where persons with disabilities were prevented from commodifying their disability and punished for begging in public. The laws also reinforced the eugenic logic of segregation through the institutionalization of disabled individuals. If we want to build inclusive and resilient cities, we must understand the historical context and beliefs that have shaped our urban landscapes. And we must address the ways in which beliefs and assumptions about personhood, citizenship, and rights have shaped and continue to shape our cities.
Constructing a New Approach to Radical Inclusion
Authors: Pineda Victor Santiago 
Published: February 2024

Abstract​​Spatial justice is an approach to social justice that takes into account the organization and utilization of geographical space and its impact on human life and social relations. Geographical location plays a key role in producing spatial injustice and exacerbating disadvantages. The social is spatial and vice versa, which is critical to understanding the experiences of marginalized individuals and communities. Despite progress in legislation, planning practitioners have not fully realized the enabling power of physical space and dominant models of disability continue to remain unjust. The organization of space and urban planning are crucial to promoting spatial justice, as studies have shown that a person’s ZIP code is a stronger predictor of health than any other factor. Public-private initiatives have often failed to consider the spatial dimension of justice in their designs and have neglected to address the exclusion of people with disabilities. The current social contract ignores the spatiality of injustice and a new social contract centered on space must be developed to reframe the problems and solutions to equity, access, and inclusion in human settlements.

Published: February 2024

ZusammenfassungDie Inhalation von weiter verarbeitetem Kokain, wie Crack oder Freebase, kann zu alveolären Hämorrhagien führen. Das klinische Bild wird als „crack lung syndrome“ bezeichnet. Schwere Verläufe sind durch Zeichen einer progredienten hypoxämischen Insuffizienz mit Ausbildung eines akuten Lungenversagens (Acute Respiratory Distress Syndrom, ARDS) gekennzeichnet. In der Computertomographie des Thorax imponieren bipulmonale Konsolidierungen und Milchglasveränderungen mit oft subpleuralen Aussparungen. Unser Fallbericht eines 48-jährigen Patienten zeigt auf, dass neben dem Ausschluss infektiöser Ursachen die sorgfältige Anamnese zur Diagnosesicherung essenziell ist.
Clustered surface amino acid residues modulate the acid stability of GH10 xylanase in fungi

Published: February 2024

Abstract
Acidic xylanases are widely used in industries such as biofuels, animal feeding, and fruit juice clarification due to their tolerance to acidic environments. However, the factors controlling their acid stability, especially in GH10 xylanases, are only partially understood. In this study, we identified a series of thermostable GH10 xylanases with optimal temperatures ranging from 70 to 90 °C, and among these, five enzymes (Xyn10C, Xyn10RE, Xyn10TC, Xyn10BS, and Xyn10PC) exhibited remarkable stability at pH 2.0. Our statistical analysis highlighted several factors contributing to the acid stability of GH10 xylanases, including electrostatic repulsion, π-π stacking, ionic bonds, hydrogen bonds, and Van der Waals interactions. Furthermore, through mutagenesis studies, we uncovered that acid stability is influenced by a complex interplay of amino acid residues. The key amino acid sites determining the acid stability of GH10 xylanases were thus elucidated, mainly concentrated in two surface regions behind the enzyme active center. Notably, the critical residues associated with acid stability markedly enhanced Xyn10RE’s thermostability by more than sixfold, indicating a potential acid-thermal interplay in GH10 xylanases. This study not only reported a series of valuable genes but also provided a range of modification targets for enhancing the acid stability of GH10 xylanases.

Key points
• Five acid stable and thermostable GH10 xylanases were reported.
• The key amino acid sites, mainly forming two enriched surface regions behind the enzyme active center, were identified responsible for acid stability of GH10 xylanases.
• The finding revealed interactive amino acid sites, offering a pathway for synergistic enhancement of both acid stability and thermostability in GH10 xylanase modifications.

Authors: Clemens Christoph R. , Alten Florian , Eter Nicole , Helbig Horst , Märker David A. 
Published: February 2024

Zusammenfassung
Hintergrund
Die intravitreale operative Medikamenteneingabe (IVOM) ist eine effiziente und risikoarme Applikationstechnik in der Behandlung unterschiedlicher Netzhauterkrankungen. Zu den seltenen schwerwiegenden Komplikationen zählen erhöhte Augeninnendrücke, Glaskörperblutungen, Netzhautrisse und -ablösungen sowie intraokulare Entzündungen und Endophthalmitiden. In der hier vorliegenden Fallserie berichten wir über iatrogene Linsenverletzungen.

Methoden
Es erfolgte eine multizentrische Datenerhebung von IVOM-Patienten mit sichtbaren iatrogenen Linsendefekten, retrospektiv über den Zeitraum 2016 bis 2023.

Ergebnisse
In 6 Fällen (69,3 Jahre ± 6,5) wurde ein Linsentrauma nach IVOM identifiziert. Während in 5 Fällen eine Anti-VEGF-Therapie vorausgegangen war, stellten wir in einem Fall eine Linsenverletzung nach Dexamethason-Implantation fest.

Schlussfolgerungen
Linsenverletzungen im Rahmen der IVOM sind eine seltene Komplikation und bei sachgemäßer Injektionstechnik vermeidbar. Kenntnisse über die individuelle Bulbusachsenlänge und den Linsenstatus tragen zusätzlich zur Vermeidung dieser Komplikation bei.
