Authors: Dai Juncheng , Liu Fangyu 
Published: June 2024

AbstractIn unraveling the profound connections between humans and place, the traditional concept of the sense of place takes on new dimensions in the digital era. This study contributes to a nuanced understanding by integrating digital and physical spaces within the context of information and communication technology (ICT). Beginning with a review of historical changes and debates surrounding the sense of place, the research establishes a foundation for understanding the evolving relationship with the place. Building on this, the study explores the intricate interplay between digital media and place, revealing how advancements in digital technology shape perceptions of the sense of place. Beyond analysis, the study introduces a three-dimensional framework for the sense of place (i.e., physical sense of place, digital sense of place, and hybrid sense of place), recognizing the dynamic relationship between individuals and their environment, incorporating the digital dimension. Firmly grounded in the perspective of relationships, this framework captures multifaceted connections individuals establish with both physical and digital spaces. Finally, the research explores practical applications of this reconceptualized sense of place. This research deepens the current understanding of the complex dynamics in constructing places in contemporary society, where digital and physical realms intertwine. This research serves as a crucial steppingstone for comprehending the evolving dynamics of the sense of place in the digital era, presenting a refined framework that captures the complex relationships between individuals, technology, and the places they inhabit.

Published: June 2024

AbstractThe COVID-19 pandemic has created significant challenges to the global economy, especially within the tourism industry. Economic downturns and psychological barriers make it even more challenging to attract tourists back. This paper explores the stimulating effect of digital travel vouchers on tourist mobility, as well as the heterogeneous effects of different vouchers modes. Using monthly data on tourist inflows in 306 cities from September 2020 to December 2021, collected by a web-crawling tool, and manually gathered information of digital travel vouchers issued during this period, our analyses show that digital travel vouchers can boost tourist inflows. Their effectiveness, however, depends on the method of issuance and the total number distributed. Furthermore, significant spillover effects among neighboring cities are found through a spatial econometric model.

Published: June 2024

Magnesium AZ91/AlN-based surface composites have been synthesized using the friction stir processing (FSP) technique. The influence of particle addition during FSP on microstructural and mechanical properties has been investigated. Composite plates of 5, 10, and 15 vol. % AlN were synthesized using two-pass FSP with an axial force of 10 KN, a tool travel speed of 40 mm/min, and a tool rotation speed of 1200 rpm. The AZ91/AlN surface composites were analyzed microscopically with the use of an optical microscope, an x-ray diffractometer, and a scanning electron microscope. The prepared composites were tested for hardness and tensile strength. Micrographs taken in the stir zone revealed a consistent distribution of AlN particles throughout the AZ91 matrix. The AZ91/AlN surface composites were tested for hardness and tensile strength, and the findings showed that the AlN particles improved the mechanical properties without significantly decreasing ductility. The fracture surfaces of the composites were studied, and the mechanisms of fracture were identified.
Integration of wavelet packet transform, residual convolution neural network, and support vector machine for series arc fault detection
Authors: Yin Zhendong , Xiao Chunyu 
Published: June 2024

Series arc fault (SAF) poses a great challenge to the safe and stable operation of civil low-voltage distribution systems. For the accurate and rapid detection of SAF, this article proposes an SAF detection method using wavelet packet transform (WPT), residual convolution neural network (RCNN), and support vector machine (SVM). First, the raw current signal is decomposed into four wavelet components based on WPT. Then, the 1-D wavelet components are converted into 2-D matrices. Afterward, the matrices are input into RCNN through different channels. Finally, the detection results can be yielded by SVM. The effectiveness of the proposed method is verified based on offline experiments. The average detection accuracy of the proposed method is 99.72%, which is higher than that of the eight comparison methods. Moreover, the results of online experiments indicate that the detection time of the proposed method is less than 100 ms and can satisfy the requirement of standard 1699.

Published: June 2024

Substituting slow oxygen evolution reaction (OER) with thermodynamically favorable urea oxidation reaction (UOR) is considered as one of the feasible strategies for achieving energy-saving hydrogen production. Herein, a uniform layer of NiMoO4 nanorods was grown on nickel foam by a hydrothermal method. Then, a series of Ni-MoOx/NF-X nanorod catalysts comprising Ni/NiO and MoOx (MoO2/MoO3) were prepared through regulating annealing atmosphere and reduction temperature. The optimized Ni-MoOx/NF-3 with a large accessible specific area can act as a bifunctional catalyst for electrocatalytic anodic UOR and cathodic hydrogen evolution reaction (HER). At a current density of 100 mA cm−2, the introduction of urea can significantly reduce the overpotential of Ni-MoOx/NF-3 by 210 mV compared to OER. In addition, Ni-MoOx/NF-3 has a higher intrinsic activity than other catalysts. It only requires −0.21 and 1.38 V to reach 100 mA cm−2 in HER and UOR, respectively. Such an excellent performance can be attributed to the synergistic function between Ni and MoOx. The presence of metallic Ni and reduced MoOx in pairs is beneficial for improving the electrical conductivity and modulating the electronic structure, resulting in enhancing the electrocatalytic performance. When assembling Ni-MoOx/NF-3 into an overall urea–water splitting system, it can achieve energy-saving hydrogen production and effective removal of urea-rich wastewater.

Authors: Goswami Anirban , Ng Nicholas , Yakubu Emmanuel , Bassen Gregory , Guchhait Samaresh 
Published: June 2024

Single crystal Cr1.27Te2 samples were synthesized by using the chemical vapor transport method. Single crystal x-ray diffraction studies show a trigonal crystal structure with a P3̄m1 symmetry space group. We then systematically investigate magnetic properties and critical behaviors of single crystal Cr1.27Te2 around its paramagnetic-to-ferromagnetic phase transition. The Arrott plot indicates a second-order magnetic phase transition. We estimate critical exponents β = 0.2631 ± 0.002, γ = 1.2314 ± 0.007, and TC = 168.48 ± 0.031 K by using the Kouvel–Fisher method. We also estimate other critical exponents δ = 5.31 ± 0.004 by analyzing the critical isotherm at TC = 168.5 K. We further verify the accuracy of our estimated critical exponents by the scaling analysis. Further analysis suggests that Cr1.27Te2 can be best described as a quasi-2D Ising magnetic system.

Published: June 2024

Objective This study aimed to examine the national variation in government-subsidised healthcare costs of residents in long-term care facilities (LTCFs) and costs differences by resident and facility characteristics. Methods A retrospective population-based cohort study was conducted using linked national aged and healthcare data of older people (≥65 years) living in 2112 LTCFs in Australia. Individuals’ pharmaceutical, out-of-hospital, hospitalisation and emergency presentations direct costs were aggregated from the linked healthcare data. Average annual healthcare costs per resident were estimated using generalised linear models, adjusting for covariates. Cost estimates were compared by resident dementia status and facility characteristics (location, ownership type and size). Results Of the 75,142 residents examined, 70% (N = 52,142) were women and 53.4% (N = 40,137) were living with dementia. The average annual healthcare cost (all costs in $A) was $9233 (95% CI $9150–$9295) per resident, with hospitalisation accounting for 47.2% of the healthcare costs. Residents without dementia had higher healthcare costs ($11,097, 95% CI $10,995–$11,200) compared to those with dementia ($7561, 95% CI $7502–$7620). Residents living in for-profit LTCFs had higher adjusted average overall annual healthcare costs ($11,324, 95% CI $11,185–$11,463) compared to those living in not-for-profit ($11,017, 95% CI $10,895–$11,139) and government ($9731, 95% CI $9365–$10,099) facilities. Conclusions The healthcare costs incurred by residents of LTCFs varied by presence of dementia and facility ownership. The variation in costs may be associated with residents’ care needs, care models and difference in quality of care across LTCFs. As hospitalisation is the biggest driver of the healthcare costs, strategies to reduce preventable hospitalisations may reduce downstream cost burden to the health system.
The Application of Scientific Evidence-Based Changes to an Animal Shelter’s Rehoming Practices
Authors: Griffin Karen E. 
Published: June 2024

Abstract
Shelters devote much of their often very limited resources to screening potential adopters, including spending copious amounts of time collecting information from them about their family structure, lifestyle, etc. However, in a study that surveyed rehoming organisations’ practices, it was found that they gather substantially more information about potential adopters than there is scientific evidence to justify. Some information gathered for which there is no scientific rationale which could cause adopters to be denied adopting any dog from the organisation. Consequently, the study concluded that organisations may be turning away perfectly suitable homes due to their often strict rehoming criteria, resulting in dogs staying with the organisation for longer than necessary. Therefore, the study recommended organisations relax their strict rehoming criteria and instead focus on ensuring adopters have appropriate expectations and education for adopting a dog. With knowledge of the study’s findings, a shelter in Northern Ireland overhauled their rehoming practices to be in line with the study’s recommendations for change. Their goal was to increase the number of animals adopted per month with a focus on ensuring successful placements, to decrease staff/volunteer workload, and for potential adopters to have an overall better experience with the shelter. Despite challenges in uptake of the changes by staff working with dogs, noteworthy improvements were observed, with the greatest improvements with cats and small animals. Three months after the shelter overhauled their rehoming practices, adoptions increased year-over-year, staff motivation and morale improved and potential adopters reported a more positive experience with the organisation.

Cherenkov radiation in a bianisotropic medium with magnetoelectric effect
Authors: Fakhrzadeh Elham , Shahabadi Mahmoud , Talebi Nahid 
Published: June 2024

Abstract
Cherenkov radiation (CR) has been extensively explored in a large variety of media; however, its characteristics in a medium showing both magnetoelectric (ME) and anisotropy effects have not been addressed so far. The aim of this study is to address this gap by analytically investigating CR in a dispersive bianisotropic medium with ME effect. In this research, founded upon a vector-potential approach, we demonstrate that notable features such as double cones of CR with different angles can be formed due to ME coupling in bianisotropic media. We also calculate the emitted electromagnetic fields to obtain radiated power and momentum-resolved electron energy-loss spectra for a medium with varying ME coefficients, as well as for a medium without ME effects in order to illustrate the impact of this coupling on the characteristics of the CR and propose methods for the characterization of ME materials.
Generation and applications of x-ray and extreme ultraviolet beams carrying orbital angular momentum
Authors: McCarter Margaret R , De Long Lance E , Todd Hastings J , Roy Sujoy 
Published: June 2024

Abstract
In addition to spin angular momentum, light can carry orbital angular momentum. The orbital angular momentum degree of freedom in the extreme ultraviolet and x-ray regimes enables fundamental studies of light–matter interactions and new methods to study materials. Advances in x-ray optics, as well as undulator radiation and high harmonic generation techniques, lead to the creation of beams with non-trivial phase structure, such as a helical phase structure, creating new possibilities for the use of extreme ultraviolet and x-ray photons with orbital angular momentum in probing complex electronic structures in matter. In this article, we review the generation and applications of orbital angular momentum beams in the x-ray and extreme ultraviolet regime. We discuss several recent works that exploit the orbital angular momentum degree of freedom and showcase the potential advantages of using these beams.
ROS-responsive celastrol-nanomedicine alleviates inflammation for dry eye disease

Published: June 2024

Abstract
Dry eye disease (DED) is a major global eye disease leading to severe eye discomfort and even vision impairment. The incidence of DED has been gradually increasing with the high frequency of use of electronic devices. It has been demonstrated that celastrol (Cel) has excellent therapeutic efficacy in ocular disorders. However, the poor water solubility and short half-life of Cel limit its further therapeutic applications. In this work, a reactive oxygen species (ROS) sensitive polymeric micelle was fabricated for Cel delivery. The micelles improve the solubility of Cel, and the resulting Cel loaded micelles exhibit an enhanced intervention effect for DED. The in vitro results demonstrated that Cel-nanomedicine had a marked ROS responsive release behavior. The results of in vitro and in vivo experiments demonstrated that Cel has excellent biological activities to alleviate inflammation in DED by inhibiting TLR4 signaling activation and reducing pro-inflammatory cytokine expression. Therefore, the Cel nanomedicine can effectively eliminate ocular inflammation, promote corneal epithelial repair, and restore the number of goblet cells and tear secretion, providing a new option for the treatment of DED.
Time-domain diffuse optical imaging technique for monitoring rheumatoid arthritis disease activity: theoretical development and in silico validation
Authors: Ioussoufovitch S , Diop M 
Published: June 2024

Abstract

Objective. Effective early treatment—within 3–5 months of disease onset—significantly improves rheumatoid arthritis (RA) prognosis. Nevertheless, 1 in 3 patients experiences treatment failure which takes 3–6 months to detect with current monitoring techniques. The aim of this work is to develop a method for extracting quantitative features from data obtained with time-domain diffuse optical imaging (TD-DOI), and demonstrate their sensitivity to RA disease activity. Approach. 80 virtual phantoms of the proximal interphalangeal joint—obtained from a realistic tissue distribution derived from magnetic resonance imaging—were created to simulate RA-induced alterations in 5 physiological parameters. TD-DOI images were generated using Monte Carlo simulations, and Poisson noise was added to each image. Subsequently, each image was convolved with an instrument response function (IRF) to mimic experimental measurements. Various spatiotemporal features were extracted from the images (i.e. statistical moments, temporal Fourier components), corrected for IRF effects, and correlated with the disease index (DI) of each phantom. Main results. Spatiotemporal Fourier components of TD-DOI images were highly correlated with DI despite the confounding effects of noise and the IRF. Moreover, lower temporal frequency components (

⩽

0.4 GHz) demonstrated greater sensitivity to small changes in disease activity than previously published spatial features extracted from the same images. Significance. Spatiotemporal components of TD-DOI images may be more sensitive to small changes in RA disease activity than previously reported DOI features. TD-DOI may enable earlier detection of RA treatment failure, which would reduce the time needed to identify treatment failure and improve patient prognosis.

JET far-infrared interferometer/polarimeter diagnostic system—40 years of lessons learned
Authors: Boboc A , Macdonald J , Felton R , Brown M J , Studholme W , Cramp S ,   the JET Operations Team
Published: June 2024

Abstract
Originally designed for 5 years of plasma operations, the JET far infrared interferometer/polarimeter diagnostic system was still operating at full capability nearly 40 years later in ITER-relevant conditions (e.g. metal wall, tungsten divertor) for multiple D–T campaigns, albeit with significantly lower neutron fluences. The original design had to be adapted substantially over the years due to machine changes, leading to reduced signal and access to mirrors etc, and the diagnostics still worked due to the excellent dynamic range of the detectors. This paper will discuss invaluable lessons learned from designing, operating, optimising and enhancing such a complex system and how these can be used for developing a new class of laser-based diagnostics for next-generation reactor-grade machines.
Winding angle optimization and testing of small-scale, non-planar, high-temperature superconducting stellarator coils
Authors: Huslage P , Kulla D , Lobsien J-F , Schuler T , Stenson E V 
Published: June 2024

Abstract
We designed and constructed two non-planar coils with high-temperature superconductors (HTS) based on shapes from the Wendelstein 7-X stellarator. Tape track orientation of the HTS was optimized to reduce the coil size as much as possible while staying within the strain limits of the gadolinium barium copper oxide (GdBCO) superconductor. This resulted in average coil radii of 0.23 m and 0.48 m at strain limits of up 0.45% to for the coil shapes that were chosen. The coils were produced by winding the GdBCO tapes onto 3D-printed plastic frames. We confirmed the integrity of the superconducting layer after winding by spatially resolved measurement of the critical current and by energizing the coils in liquid nitrogen. Coil 1 showed a resistance of

1.75

μ
Ω

and did not have any critical current degradation, while coil 5 had a resistance of

195

μ
Ω

and showed only one dropout, attributable to a handling error. We measured the magnetic field of the coil with a three-axis Hall probe system and found good agreement with predictions. This work demonstrates the manufacturing of small-scale, non-planar magnetic coils from commercially available HTS.

Abstract
The semiclassical non-perturbative atomic orbital close-coupling approach has been employed to study the electron capture and excitation processes in He2+–H(1s) and He2+–H(2s) collision systems. In order to ensure the accuracy of our calculated cross sections, a large number of high excited states and pseudostates are included in the expansion basis sets which are centered on the target and projectile, respectively. The total and partial charge transfer and excitation cross sections are obtained for a wide-energy domain ranging from 1 keV/amu to 200 keV/amu. The present calculations are also compared with the results from other theoretical methods. These cross section data are useful for the investigation of astrophysics and laboratory plasma.
HiFAST: An H i Data Calibration and Imaging Pipeline for FAST. II. Flux Density Calibration
Authors: Liu Ziming , Wang Jie , Jing Yingjie , Zhang Zhi-Yu , Xu Chen , Liang Tiantian , Chen Qingze , Tang Ningyu , Yang Qingliang 
Published: June 2024

Abstract
Accurate flux density calibration is essential for precise analysis and interpretation of observations across different observation modes and instruments. In this research, we first introduce the flux calibration model that incorporated in HiFAST pipeline, and designed for processing H i 21 cm spectra. Furthermore, we investigate different calibration techniques and assess the dependence of the gain parameter on the time and environmental factors. A comparison is carried out in various observation modes (e.g., tracking and scanning modes) to determine the flux density gain (G), revealing insignificant discrepancies in G among different methods. Long-term monitoring data shows a linear correlation between G and atmospheric temperature. After subtracting the G–Temperature dependence, the dispersion of G is reduced to <3% over a one-year timescale. The stability of the receiver response of Five-hundred-meter Aperture Spherical radio Telescope (FAST) is considered sufficient to facilitate H i observations that can accommodate a moderate error in flux calibration (e.g., > ∼ 5%) when utilizing a constant G for calibration purposes. Our study will serve as a useful addition to the results provided by Jiang et al. Detailed measurement of G for the 19 beams of FAST, covering the frequency range 1000–1500 MHz, can be found on the HiFAST homepage: https://hifast.readthedocs.io/fluxgain.
