Abstract
Energy resolved neutron imaging has developed rapidly due to
its advantage on testing the inner structure of crystal
samples. Neutron detector is one of the key components to determine
the imaging results quality. The neutron sensitive microchannel
plate (nMCP) has been widely used in energy resolved neutron imaging
experiments because of the high spatial and timing
resolution. However, the ability to adjust field-of-view (FOV) and
spatial resolution has not been realized in the nMCP detector, which
is an attractive capability in energy resolved neutron imaging
experiments. In this paper, an energy resolved neutron imaging
detector was developed by coupling nMCP with a time stamping
camera. The neutrons were absorbed by nMCP and converted into light
through a phosphor screen. Then the light was focused on the camera
by optical lens. A data algorithm was designed to improve the data
quality. By changing the magnification of the optical lens, large
FOV (46mm diameter) and high spatial resolution (26 μm) were
realized in the experiments at CSNS beamline 20. The energy resolved
ability was demonstrated by a Bragg-edge transmission imaging
experiment for aluminum and stainless-steel samples. The performance
of this detector makes it a promising candidate used in energy
resolved neutron imaging.

Authors: Zhou Ji , Zhao Zhenyu , Zou Zhimin , Ding Yanhuai 
Published: January 2024

Abstract
Foam concrete is one of the most valuable porous materials used in civil and industrial buildings. Sepiolite, a fibrous hydrous magnesium silicate, possesses exceptional qualities such as a low thermal conductivity, non-polluting nature, and eco-friendliness. In this paper, a multi-functional sepiolite-based foam concrete has been fabricated using a physical foaming technology. The high sepiolite content and unique hierarchical structure endow the foam concrete with excellent adsorption and thermal insulation properties. The foam concrete exhibits a high adsorption capacity towards methanal and ammonia gases. Furthermore, the foam concrete, with its high porosity and good forming ability, shows great potential for application in thermal-insulation materials and wastewater treatment.

Published: January 2024

Abstract
Elastic, bendable and stretchable electronics establish a new and promising area of multi-physics engineering for a variety of applications, e.g. on wearables or in complex-shaped machine parts. While the area of metamorphic electronics has been investigated comprehensively, the behavior at radio frequencies (RFs), especially in the GHz range, is much less well studied. The mechanical deformation of the soft substrates, for instance, due to stretching, changes the geometrical dimensions and the electrical properties of RF transmission lines. This effect could be desirable in some cases, e.g. for smart devices with shape-dependent transmission or radiation characteristics, or undesirable in other cases, e.g. in feed and distribution networks due to the variable electrical lengths and thus phase variations. This contribution describes the results of a systematic study of the broadband RF properties of coplanar transmission lines on Ecoflex® substrates, based on numerical simulations and experimental data. Two types of stretchable transmission line structures were studied: Meander- and circular ring-segmented lines. Modeling and simulation were performed combining a 2D circuit simulation software with electromagnetic full-wave simulations. The experimental part of the work included the fabrication of metamorphic substrates metallized with thin copper layers and systematic measurements of the electrical lengths and phase constants of coplanar waveguides in the frequency range from 1 to 5 GHz based on vector network analysis for different stretching levels. With the given substrate technology, we succeeded in demonstrating stretchability up to a level of 21%, while the theoretical limit is expected at 57%. The meander- and circular-shaped line structures revealed markedly different sensitivities to the stretching level, which was lower for circular structures compared to the meander structures by approximately a factor of three.
ANFIS-based FOPID controller to enhanced stability of cascaded converter for electric vehicle (EV) charger
Authors: Gupta Ravishankar , Singh Navdeep 
Published: January 2024

Abstract
In an electric vehicle (EV) charger system, a two-stage conversion process is integrated and cascaded with a voltage source converter (VSC) and a Dual active bridge converter (DAB). These impedances VSC outputs impedance (ZoutVSC(s)) and DAB have input impedance (ZinDAB(s)) interact, leading to voltage fluctuation and power loss. To address the cascaded converter’s impedance interaction, the modified controller that combines an adaptive Neuro-fuzzy inference system (ANFIS) based fractional order proportional integral derivative (FOPID) controller is used with effective active damping (AD). The modified controller (ANFIS + FOPID + AD) uses ANFIS’s skills to capture and predict the system’s nonlinear behaviour, using its trained data to guide the FOPID’s parameter. The presence of AD ensures the sorting out of impedance interaction problems. Compared to the PID controller, the FOPID controller includes two more degrees of freedom and offers superior adaptability and performance. The effectiveness of the modified controller is tested via frequency response analysis and time domain simulations. Time domain simulations underscore the advantage of the modified controller (ANFIS + FOPID + AD), revealing a remarkable 30% settling time and a 25% overshoot compared to the (FOPID + AD) controller. It is better regarding flexibility, faster response time, and improved system stability. The system performance has been validated and compared by simulation process and HIL technique OPAL RT OP44512.
A proximal policy optimization with curiosity algorithm for virtual drone navigation
Authors: Das Rupayan , Khan Angshuman , Paul Gunjan 
Published: January 2024

Abstract
The drone sector is witnessing a surge in demand for advanced models tailored to address critical applications such as disaster management and intelligent warehouse deliveries. Employing simulation-based experiments with virtual drone navigation is considered a best practice before deploying physical models. Nonetheless, the current state-of-the-art virtual drone navigation system lacks accuracy and introduces notable increments in simulation time. In order to mitigate these issues, this paper introduces a deep reinforcement learning-based drone agent, designed to autonomously navigate within a constrained virtual environment. The proposed drone agent utilizes realistic drone physics in order to ensure flight within the virtual environment. The work uniquely combines & optimizes both control algorithms and physical dynamics, making the model more robust and versatile than others. The integration of curiosity-driven learning with physics-based modeling potentially increases the model's readiness for real-world application, compared to theoretical approaches. The extensive simulation results validate the remarkable speed and accuracy of the proposed scheme compared to baseline works. The trained agent exhibits strength and versatility, enabling it to deal with the numerous targets and obstacles encountered in human environments.
Warm Arctic–Cold Eurasia pattern driven by atmospheric blocking in models and observations
Authors: Kaufman Zachary , Feldl Nicole , Beaulieu Claudie 
Published: January 2024

Abstract
In recent decades, Arctic-amplified warming and sea-ice loss coincided with a prolonged wintertime Eurasian cooling trend. This observed Warm Arctic–Cold Eurasia pattern has occasionally been attributed to sea-ice forced changes in the midlatitude atmospheric circulation, implying an anthropogenic cause. However, comprehensive climate change simulations do not produce Eurasian cooling, instead suggesting a role for unforced atmospheric variability. This study seeks to clarify the source of this model-observation discrepancy by developing a statistical approach that enables direct comparison of Arctic-midlatitude interactions. In both historical simulations and observations, we first identify Ural blocking as the primary causal driver of sea ice, temperature, and circulation anomalies consistent with the Warm Arctic–Cold Eurasia pattern. Next, we quantify distinct transient responses to this Ural blocking, which explain the model-observation discrepancy in historical Eurasian temperature. Observed 1988–2012 Eurasian cooling occurs in response to a pronounced positive trend in Ural sea-level pressure, temporarily masking long-term midlatitude warming. This observed sea-level pressure trend lies at the outer edge of simulated variability in a fully coupled large ensemble, where smaller sea-level pressure trends have little impact on the ensemble mean temperature trend over Eurasia. Accounting for these differences bring observed and simulated trends into remarkable agreement. Finally, we quantify the influence of sea-ice loss on the magnitude of the observed Ural sea-level pressure trend, an effect that is absent in historical simulations. These results illustrate that sea-ice loss and tropospheric variability can both play a role in producing Eurasian cooling. Furthermore, by conducting a direct model-observation comparison, we reveal a key difference in the causal structures characterizing the Warm Arctic–Cold Eurasia Pattern, which will guide ongoing efforts to explain the lack of Eurasian cooling in climate change simulations.
Evaluating individual tree species classification performance across diverse environments

Published: January 2024

Abstract
Vegetation species mapping using airborne imaging spectroscopy yields accurate results and is important for advancing conservation objectives and biogeographic studies. As these data become more readily available owing to the upcoming launch of spaceborne imaging spectrometers, it is necessary to understand how these data can be used to consistently classify species across large geographic scales. However, few studies have attempted to map species across multiple ecosystems; therefore, little is known regarding the effect of intra-specific variation on the mapping of a single species across a wide range of environments and among varying backgrounds of other non-target species. To explore this effect, we developed and tested species classification models for Metrosideros polymorpha, a highly polymorphic canopy species endemic to Hawai’i, which is found in a diverse array of ecosystems. We compared the accuracies of support vector machine (SVM) and random forest models trained on canopy reflectance data from each of eight distinct ecosystems (ecosystem-specific) and a universal model trained on data from all ecosystems. When applied to ecosystem-specific test datasets, the ecosystem-specific models outperformed the universal model; however, the universal model retained high (>81%) accuracies across all ecosystems. Additionally, we found that models from ecosystems with broad variation in M. polymorpha canopy traits, as estimated using chemometric equations applied to canopy spectra, accurately predicted M. polymorpha in other ecosystems. While species classifications across ecosystems can yield accurate results, these results will require sampling procedures that capture the intra-specific variation of the target species.
Health and Safety Executive research on wood dust exposure controls in British manufacturing
Authors: Simpson Andrew T , Beattie Helen , Lekka Chrysanthi , Keen Chris 
Published: January 2024

Abstract
To generate new intelligence on occupational exposure to wood dust in woodworking manufacturing activities in Britain, the Health and Safety Executive (HSE) performed 22 occupational hygiene site visits to assess exposure and exposure controls between 2014 and 2017. The work aimed to characterise good practice and therefore sites with a poor health and safety record, as identified from HSE inspection records, were not invited to participate. Sites selected covered furniture production, joinery, saw milling, and boat building and repair. Twenty-three follow-up telephone interviews were also carried out across 15 of the companies with supervisors and managers to explore how they tried to promote good practice among the workforce, and if there are any potential challenges encountered. The aim of the interviews was to gain a better understanding of how to enable organisations to improve the management of wood dust exposure.
This study found that 6.0% of all wood dust exposure measurements (15 out of 252) were above 5 mg/m³, and 17.6% of exposures to hardwood dust or mixtures of hardwood and softwood dust (38 out of 216) were above 3 mg/m³ (the then current and future workplace exposure limits). Sanding, cleaning, and maintenance activities were of particular concern. Improvements to exposure controls are required, in particular, improvements to local exhaust ventilation controls for hand-held power tools and hand sanding. The management, selection, and use of respiratory protective equipment were poor.
All the managers and supervisors recognised that exposure to wood dust can pose serious health risks, and that controls were crucial to protecting workers’ health. The findings from the telephone interviews suggest that supervision and provision of information about the health effects of exposure to wood dust were common approaches that organisations used to raise awareness and promote good practice, in relation to managing wood dust exposure. Worker attitudes towards controls, such as perceptions that they hinder task completion and habitual ways of working, were identified as factors influencing the use of controls. Risk communication approaches that focus on increasing workers’ awareness of their susceptibility to ill-health using credible sources, such as peers, can help enhance the uptake of messages on the use of controls. Financial constraints were identified as a challenge to improving the control of wood dust, particularly for small companies.
Constricted rights and imagined identities: Peace and accountability processes and constitution-making in Bosnia and Herzegovina
Authors: Begicevic Alma , Balint Jennifer 
Published: January 2024

Abstract
This article takes an interdisciplinary law-in-context approach to examine the nature of constitutionalism in Bosnia and Herzegovina. We argue that while the new constitution was necessary for implementing the postwar democratic transition and rebuilding processes, its fixed ethno-religious collective political identities achieved between 1992 and 1995 by forceful means have further reinforced ethno-territorial divisions in a multicultural society. As a consequence,the individual and state accountability for mass atrocities and genocide before the ad hoc International Criminal Tribunal for Former Yugoslavia and theInternational Court of Justice have become secondary to the postwar power-sharing arrangement, thus perpetuating inter-ethnic tensions. The dominant focus on a social order that reasserts citizenship and constitutional rights based on ethnic identities has created an enduring deadlock for the Bosnian transition. This article reimagines a citizen-based constitution generated by political participation for those in and outside of Bosnia and Herzegovina that safeguards the principles of non-discrimination and equal civil, political, socio-economic, and cultural rights, and encourages citizens’ education and democratic participation to shape the future of democracy.
Spatial organization of a soil cyanobacterium and its cyanosphere through GABA/Glu signaling to optimize mutualistic nitrogen fixation
Authors: Nelson Corey , Dadi Pavani , Shah Dhara D , Garcia-Pichel Ferran 
Published: January 2024

Abstract
Soil biocrusts are characterized by the spatial self-organization of resident microbial populations at small scales. The cyanobacterium Microcoleus vaginatus, a prominent primary producer and pioneer biocrust former, relies on a mutualistic carbon (C) for nitrogen (N) exchange with its heterotrophic cyanosphere microbiome, a mutualism that may be optimized through the ability of the cyanobacterium to aggregate into bundles of trichomes. Testing both environmental populations and representative isolates, we show that the proximity of mutualistic diazotroph populations results in M. vaginatus bundle formation orchestrated through chemophobic and chemokinetic responses to gamma-aminobutyric acid (GABA) /glutamate (Glu) signals. The signaling system is characterized by: a high GABA sensitivity (nM range) and low Glu sensitivity (μM to mM), the fact that GABA and Glu are produced by the cyanobacterium as an autoinduction response to N deficiency, and by the presence of interspecific signaling by heterotrophs in response to C limitation. Further, it crucially switches from a positive to a negative feedback loop with increasing GABA concentration, thus setting maximal bundle sizes. The unprecedented use of GABA/Glu as an intra- and interspecific signal in the spatial organization of microbiomes highlights the pair as truly universal infochemicals.

Abstract

Objectives
We sought to analyse the antibiotic susceptibility profiles and molecular epidemiology of MDR clinical Pseudomonas aeruginosa isolates from South India using non-MDR isolates as a reference.

Methods
We established a comprehensive clinical strain library consisting of 58 isolates collected from patients across the South Indian state of Kerala from March 2017 to July 2019. The strains were subject to antibiotic susceptibility testing, modified carbapenem inactivation method assay for carbapenemase production, PCR sequencing, comparative sequence analysis and quantitative PCR of MDR determinants associated with antibiotic efflux pump systems, fluoroquinolone resistance and carbapenem resistance. We performed in silico modelling of MDR-specific SNPs.

Results
Of our collection of South Indian P. aeruginosa clinical isolates, 74.1% were MDR and 55.8% were resistant to the entire panel of antibiotics tested. All MDR isolates were resistant to levofloxacin and 93% were resistant to meropenem. We identified seven distinct, MDR-specific mutations in nalD, three of which are novel. mexA was significantly overexpressed in strains that were resistant to the entire test antibiotic panel while gyrA and gyrB were overexpressed in MDR isolates. Mutations in fluoroquinolone determinants were significantly associated with MDR phenotype and a novel GyrA Y100C substitution was observed. Carbapenem resistance in MDR isolates was associated with loss-of-function mutations in oprD and high prevalence of NDM (blaNDM-1) within our sample.

Conclusions
This study provides insight into MDR mechanisms adopted by P. aeruginosa clinical isolates, which may guide the potential development of therapeutic regimens to improve clinical outcomes.
Autonomy, rationality, and religious initiation: replies to Hand, Wareham, Gheaus, Lewin, and Clayton
Authors: Tillson John 
Published: January 2024

Abstract
John Tillson concludes the symposium on his Children, Religion and the Ethics of Influence by replying to his five respondents. The reply focusses on Michael Hand’s defence of parental rights to raise their children in their faith; Ruth Wareham’s suggestion that the value of autonomy rules out a wider range of impermissible religious influences than Tillson’s account is able to; David Lewin’s alternative criteria for ethical influence and scepticism about rationality’s objectivity; Anca Gheaus’ proposal that initiation into multiple contradictory religious faiths is permissible; and Matthew Clayton’s rejection of the book’s perfectionist political morality.
An untimely vocation: Gadamer’s ‘Wissenschaft als Beruf. Über den Ruf und Beruf der Wissenschaft in unserer Zeit’ (1943)
Authors: Bey Facundo Norberto 
Published: January 2024

Abstract
On 27 September 1943, Hans-Georg Gadamer published a brief but significant article in the conservative newspaper Leipziger Neueste Nachrichten und Handels-Zeitung, entitled ‘Wissenschaft als Beruf. Über den Ruf und Beruf der Wissenschaft in unserer Zeit’ (Science as Vocation: On the Calling and Profession of Science in Our Time). The article, which addressed the problem of the value and status of science and philosophy in the midst of the Second World War, was never reprinted in Gadamer’s work, neither in the ten volumes of his collected writings published by Mohr Siebeck, nor separately in books or journals. I offer here a critical introduction to the context and main contents of this text due to its philosophical, political, and historical relevance. In particular, the introduction analyses Gadamer’s confrontation with his own time through explicit and implicit references to Max Weber’s 1917 lecture, ‘Wissenschaft als Beruf’ (Science as Vocation), and traces echoes in Gadamer’s later works that bear on contemporary challenges. Following that, I present the first English translation of Gadamer’s original German text.
Statistics did not prove that the Huanan Seafood Wholesale Market was the early epicentre of the COVID-19 pandemic
Authors: Stoyan Dietrich , Chiu Sung Nok 
Published: January 2024

Abstract
In a recent prominent study, Worobey et al. (2022. The Huanan Seafood Wholesale Market in Wuhan was the early epicenter of the COVID-19 pandemic. Science, 377(6609), 951–959) purported to demonstrate statistically that the Huanan Seafood Wholesale Market was the epicentre of the early COVID-19 epidemic. We show that this statistical conclusion is invalid on two grounds: (a) The assumption that a centroid of early case locations or another simply constructed point is the origin of an epidemic is unproved. (b) A Monte Carlo test used to conclude that no other location than the seafood market can be the origin is flawed. Hence, the question of the origin of the pandemic has not been answered by their statistical analysis.
