AbstractThe skin barrier is essential to prevent pathogenic invasion. When injury occurs, multiple biological pathways are promptly activated and wound repair processes are triggered. The effective healing of wounds is essential for survival, and dysfunction could result from aberrant wound repair. Preparation of many hydrogels, which involve the addition of growth/cell factors or mimic extracellular matrix (ECM) components, has not resulted in significant advances in tissue recovery. ECM contains a large number of biologically active molecules that activate a variety of cellular transduction pathways, which are essential for wound repair. Here, this work prepares hyaluronic acid‐dopamine‐thiourea (HA‐DA‐NCSN) hydrogels exhibiting ultrafast gelation in situ, following the methods of Xu et al., and subsequently designs a hydrogel containing ECM particles. In addition, the loaded ECM material, specifically decellularized ECM material, not only enhances the strength of the hydrogel network, but also delivers bioactive substances that make it a suitable platform for skin wound repair. The ECM hydrogel has great potential as an efficient bioactive wound dressing. This research suggests that this strategy is likely to improve skin wound closure in rat skin wound models.

Published: March 2024

AbstractMolybdenum trioxide/indium/silver/indium/molybdenum trioxide layers were evaporated on the polyethylene terephthalate and glass substrates using thermal evaporation coating machine. In this study, we compare the electrical, optical, and topological properties of dielectric/metal/dielectric fabricated on the polyethylene terephthalate substrate and glass substrate. In this way, the influence of dielectric and metal thicknesses on the electroptical behavior and topological properties of the transparent conductive film are studied. Furthermore, the influence of the substrate temperature on the physical properties of prepared thin films is investigated. The results show that by increasing molybdenum trioxide film thickness, the sheet resistance increases. We find that the prepared thin films on the glass substrate has high optical transmittance with respect to its on the polyethylene terephthalate substrate. We also find that by increasing the substrate temperature, figure of merit decreases. It means that the maximum figure of merit is achieved at the room substrate temperature.

AbstractTo study the influence of nickel addition on the microstructure, mechanical and lubricated wear properties of Zn‐40Al‐2Cu alloy, one ternary and five quaternary Zn‐40Al‐2Cu‐(0.5‐2.5)Ni alloys were made by permanent mold casting. The wear behavior of these alloys was studied using a block‐on‐cylinder type test machine, after examining their microstructural and mechanical features. The microstructure of Zn‐40Al‐2Cu alloy was comprised of aluminum‐rich α dendrites and a eutectoid α+η phase mixture. The addition of nickel caused the formation of intermetallic Al3Ni particles in the microstructure of this alloy. As the nickel content of alloys increased their hardness, friction coefficient, working temperature, and average surface roughness increased to certain extents but their strength, ductility, impact resistance, and wear volume decreased. However, the values of their wear volume and average surface roughness exhibited opposite changes with increasing nickel content. The worn surfaces of Zn‐40Al‐2Cu‐Ni alloys were observed to be characterized by smearing and scratching marks. Furthermore, the wear and mechanical properties of these alloys were correlated, and the results were discussed in terms of their microstructural features. Finally, it may be concluded that the nickel addition adversely affects the ductility of Zn‐40Al‐2Cu alloy but increases its wear resistance.

Published: March 2024

AbstractNatural fiber‐reinforced composites play a vital role in all areas due to their significant material properties. In this investigation, abaca/ jute fiber reinforced with rice husk filler hybrid composites have been prepared through a compression moulding process. Three different compositions of laminates were prepared with weight percentages of rice husk filler such as 1 wt. %, 2 wt. %, and 3 wt. %. Further, the mechanical properties of the prepared hybrid composite have been investigated as per the ASTM standards. Fourier transform‐infrared spectroscopy analysis has also been carried out to study the organic groups formed in the prepared hybrid composites. The tensile morphology of the material has also been carried out using scanning electron microscopy, to study the bonding of the fiber and the hybrid matrix. The analysis revealed that the mechanical properties of the hybrid composite were improved by the inclusion of rice husk as a filler. From the tensile morphology, the addition of rice husk increases the surface area of the matrix material, which results in an improvement in the bonding between the matrix and the reinforcement.
Digital firm regulation strategy with privacy data protection costs
Authors: Lv Hongjun 
Published: March 2024

AbstractAlthough the significant effects of protecting users' private data in the era of the digital economy have been recognized, digital firm regulation strategies based on privacy data protection costs remain unclear. We propose a theoretical model in which users have different perceived risks related to their personal data disclosure. We characterize how the revenue model of a digital firm shapes its optimal data regulation strategies. We show that the optimal digital service and profit have a positive correlation with the marginal value of two types of user privacy data and a negative correlation with regulatory costs. In addition, the digital firm's optimal digital services and profits are lowest under data privacy regulation at a cost for all users. More important, through the regulation of the social planner, digital firms both improve their digital services and enhance user welfare, which truly achieves the purpose of a “win‐win” outcome.
Executive turnover, internal control and accounting information comparability
Authors: Jiang Minxing , Chen Jiachen , He Yijiang 
Published: March 2024

AbstractThis paper aims to explore the causality between executive turnover and accounting information comparability (AIC) within the context of Chinese‐listed companies. The evidence with robustness tests strongly supports that the executive turnover hurts accounting comparability of corporations. These effects are more salient in the subsamples of non‐state‐owned and non‐high‐tech firms relative to state‐owned and high‐tech ones. The negative effects of executive turnover on AIC are restrained given less internal control weakness. The findings highlight the role of internal controls in ensuring AIC, and offer insights to inform the formulation of related management policies following a new executive appointment.
PET/SPECT/Spectral‐CT/CBCT imaging in a small‐animal radiation therapy platform: A Monte Carlo study—Part II: Biologically guided radiotherapy

Published: March 2024

AbstractBackgroundThis study addresses the technical gap between clinical radiation therapy (RT) and preclinical small‐animal RT, hindering the comprehensive validation of innovative clinical RT approaches in small‐animal models of cancer and the translation of preclinical RT studies into clinical practices.PurposeThe main aim was to explore the feasibility of biologically guided RT implemented within a small‐animal radiation therapy (SART) platform, with integrated quad‐modal on‐board positron emission tomography (PET), single‐photon emission computed tomography, photon‐counting spectral CT, and cone‐beam CT (CBCT) imaging, in a Monte Carlo model as a proof‐of‐concept.MethodsWe developed a SART workflow employing quad‐modal imaging guidance, integrating multimodal image‐guided RT and emission‐guided RT (EGRT). The EGRT algorithm was outlined using positron signals from a PET radiotracer, enabling near real‐time adjustments to radiation treatment beams for precise targeting in the presence of a 2‐mm setup error. Molecular image‐guided RT, incorporating a dose escalation/de‐escalation scheme, was demonstrated using a simulated phantom with a dose painting plan. The plan involved delivering a low dose to the CBCT‐delineated planning target volume (PTV) and a high dose boosted to the highly active biological target volume (hBTV) identified by the 18F‐PET image. Additionally, the Bayesian eigentissue decomposition method illustrated the quantitative decomposition of radiotherapy‐related parameters, specifically iodine uptake fraction and virtual noncontrast (VNC) electron density, using a simulated phantom with Kidney1 and Liver2 inserts mixed with an iodine contrast agent at electron fractions of 0.01–0.02.ResultsEGRT simulations generated over 4,000 beamlet responses in dose slice deliveries and illustrated superior dose coverage and distribution with significantly lower doses delivered to normal tissues, even with a 2‐mm setup error introduced, demonstrating the robustness of the novel EGRT scheme compared to conventional image‐guided RT. In the dose‐painting plan, doubling the dose to the hBTV while maintaining a low dose for the PTV resulted in an organ‐at‐risk (OAR) dose comparable to the low‐dose treatment for the PTV alone. Furthermore, the decomposition of radiotherapy‐related parameters in Kidney1 and Liver2 inserts, including iodine uptake fractions and VNC electron densities, exhibited average relative errors of less than 1.0% and 2.5%, respectively.ConclusionsThe results demonstrated the successful implementation of biologically guided RT within the proposed quad‐model image‐guided SART platform, with potential applications in preclinical RT and adaptive RT studies.

Published: March 2024

AbstractThe numerical simulation of seepage in fractured porous media holds significant relevance for subsurface energy development. The presence of fractures at various scales profoundly influences the hydraulic properties of porous media during seepage. A peridynamic (PD)‐based frame is proposed for the seepage problem analysis of multiscale fractured porous media, in which micro‐fractures are implicitly represented like the porous media, macro‐fractures are explicitly represented. For fluid flow modeling, the peridynamic bonds are divided into three types: pore seepage bond, fracture seepage bond, and fluid exchange bond. The micro‐permeabilities of different bonds are derived by Darcy's law, Poiseuille's law, and fluid exchange model, respectively. The proposed peridynamic model can naturally simulate the seepage problem of porous rock with multiscale fractures in a unified framework. Then, four cases of pore seepage and fracture seepage are analyzed using the proposed model, fractured porous media seepage with micro‐fractures and macro‐fractures are respectively considered. The predicted results are compared with the available theoretical solutions, the close agreement shows that the wide validity and applicability of the proposed model in multiscale seepage problems.

AbstractObjectiveThe objective of this study was to determine the role of body fat percentage (BFP) changes in diabetes remission (DR) and the association between baseline body composition and its changes after bariatric surgery.MethodsWe analyzed 203 patients with type 2 diabetes who underwent Roux‐en‐Y gastric bypass. Body composition was measured using a gold‐standard‐derived predictive equation and magnetic resonance imaging. Body composition changes were calculated as 100 × (baseline value – follow‐up value)/baseline value. We verified the results in a laparoscopic sleeve gastrectomy cohort with 311 patients.ResultsCompared with non‐remission patients in the Roux‐en‐Y gastric bypass cohort, those who achieved DR showed a higher baseline fat‐free mass index (FFMI) and experienced the most significant changes in BFP (p < 0.001). In comparative analyses, BFP changes were significantly better than BMI changes in identifying short‐ and long‐term DR. Linear regression analysis identified FFMI as the most significant baseline variable correlated with BFP changes (p < 0.001). Baseline BMI was positively correlated with changes in BFP but negatively correlated with changes in FFMI. These findings were replicated in the laparoscopic sleeve gastrectomy cohort.ConclusionsBFP changes determine DR after bariatric surgery, and baseline FFMI is crucial for BFP changes. A low initial BMI is associated with a smaller BFP reduction and greater FFMI loss after bariatric surgery.

AbstractObjectiveDichlorodiphenyldichloroethylene (DDE), an obesogen accumulating in adipose tissue, is released into circulation with weight loss, although its impact is underexplored among adolescents. We tested the association using an integrative translational approach of epidemiological analysis among adolescents with obesity and in vitro measures exploring the impact of DDE on adipogenesis via preadipocytes.MethodsWe included 63 participants from the Teen‐Longitudinal Assessment of Bariatric Surgery (Teen‐LABS) cohort. We assessed 4,4′‐DDE in visceral adipose tissue at surgery and BMI and waist circumference at surgery and 0.5, 1, 3, and 5 years after. We conducted longitudinal analysis to estimate the interaction on weight loss between DDE and time since surgery. In vitro analysis quantified adipogenic differentiation in commercial human preadipocytes exposed to 4,4′‐DDE via fluorescent staining and imaging.ResultsA dose–response relationship was observed, with the low‐exposure group having a greater reduction in BMI during the first year compared to higher‐exposure groups and showing smaller regains compared to higher‐exposure groups after the first year. In vitro analysis of preadipocytes treated with 4,4′‐DDE during adipogenic differentiation for 12 days showed a concentration‐dependent increase in lipid accumulation.ConclusionsDDE could contribute to weight trajectory among adolescents undergoing bariatric surgery, potentially mediated via promoted adipogenesis in preadipocytes.

Published: March 2024

AbstractA touchable plasma device based on coplanar dielectric barrier discharge (CDBD) is designed for hand hygiene. The biological safety is evaluated from the aspects of electrical and thermal properties. The peak value of current through the human body (~3.5 mA) and the highest device surface temperature (~40°C) are lower than the threshold of perception current and thermal damage temperature, respectively. The typical bacteria that are present on our hands in daily life Escherichia coli and Staphylococcus aureus are selected to verify the sterilization performance of the device. The results of human contact safety evaluation and sterilization test have demonstrated that this proposed CDBD device is reliable and user‐friendly for applications in hand hygiene.

ABSTRACTThe distributive characteristics of snow cover and their impacting mechanisms on ground thermal regimes in Northeast China remain evasive because of limited systematic studies. In this study, based on long‐term ground‐based observational data and auxiliary topographic data, geographically weighted regression kriging (GWRK) method and the temperature at the top of permafrost (TTOP) model were used to analyze the influences of snow cover duration (SCD) and average snow depth over the SCD (ASDSCD) on the thermal regimes of Xing'an permafrost in Northeast China in the 1960s–2010s. The results show a remarkable reduction of permafrost extent in Northeast China from the 1960s to 2010s, with an average reduction rate of 4.115 × 104 km2/decade. In permafrost regions, from the 1960s to 2010s, average SCD varied between 150 and 160 days, and the regional average of ASDSCD between 8 and 14 cm. Increases in ASDSCD led to a rise of TTOP. From the 1960s to 2010s, the regional average of ASDSCD increased by 3.53 cm, and that of TTOP by 2.02°C. The research results can provide scientific basis and data support for evaluating the responses of permafrost and cold region ecosystems to climate change in Northeast China.

Published: March 2024

AbstractRabies, commonly referred to as the endemic disease of the impoverished in Pakistan, remains a significant public health concern. Globally, it contributes to over 55,000 fatalities annually, with 31,000 cases reported in Asia, predominantly among children. In Karachi, the yearly occurrence of rabies ranges between 7 and 9.8 cases per million individuals. However, the actual burden is likely underestimated due to underreporting. Key challenges in Pakistan include limited awareness and increasing dog bite incidents. To address this, comprehensive educational programs focusing on proper wound care, the ineffectiveness of homemade remedies, the importance of early medical intervention, and the administration of vaccines and post‐exposure prophylaxis are imperative. Implementing a One Health model, encompassing mass vaccination, cost‐effective treatments, training on intradermal vaccine administration, accurate data collection, and community awareness initiatives, is essential for rabies control. This article aims to provide policymakers and scholars with valuable insights into the primary factors and challenges of controlling endemic human rabies in Pakistan and proposes effective strategies for its control, with the ultimate goal of achieving rabies‐free status by 2030.
Spectrum of Gyrotropic Modes and Energy Transfer between Dipolar‐Coupled Magnetic Vortices in a Square Lattice via Triggered Vortex Gyration: A Promise for Spintronics Technology
Authors: Bhattacharjee Payal , Barman Anjan , Barman Saswati 
Published: March 2024

AbstractThe atoms in a crystal lattice vibrate together and generate vibrational modes known as acoustic and optical phonon modes. Similarly, collective vortex gyration motion can be generated in artificial magnetic vortex lattices, created from periodically arranged nanodisks of specific dimensions and aspect ratios. This study uses micromagnetic simulations to characterize the spectra of gyrotropic modes in two‐dimensional magnetic vortex‐based, tailor‐made square lattice arrangements. The shifting of mode frequencies and mode splitting is witnessed depending on the vortex configurations in the lattice. The obtained gyrotropic modes are analogous to two‐dimensional square lattice structures exhibiting acoustic and optical phonon modes. The dynamics of magnetic vortices are also discussed in the transfer of magnetic energy at three points along the three high symmetry directions of the lattice when the central magnetic vortex is excited by a spin‐polarized current with an excitation frequency equal to the collective gyrotropic frequencies of the vortices. Similar to the higher contribution of acoustic phonon modes in the heat transmission process in a crystal lattice, acoustic‐like gyrotropic modes transfer more energy than optical‐like gyration modes in the vortex lattices. These magnetic metastructures hold promise for novel applications in magnetic waveguides and information processing devices, as well as for advancing spintronics.
Social media and crowdsourcing in disaster risk management: Trends, gaps, and insights from the current state of research

Published: March 2024

AbstractSocial media and crowdsourcing (SMCS) are increasingly used as tools to govern disasters. Nevertheless, we have a limited understanding of how these technologies support disaster risk management (DRM). Based on a comprehensive literature review of 237 papers, we present a state‐of‐the‐art of the research field linking SMCS with DRM. The paper provides insights into major trends in research published from 2008 to 2023. It maps the use of SMCS across disaster phases, disaster types, research design, and geographies before and after the coronavirus disease 2019 (COVID‐19) pandemic. Our results show that existing research predominantly focuses on preparedness and response activities. Moreover, research on SMCS tends to favor (single) case studies and secondary data, and despite a minor shift following the COVID‐19 pandemic, research is dominated by North America, South Asia, Australia, and Europe. There is very little research coming from severely disaster‐prone regions in the Global South on SMCS in disasters with a few exceptions. Research should focus on the power shifts that these technologies produce, the contexts in which they are supposed to be applied, and the sociocultural conditions that co‐produce, potentially vulnerable, outcomes of SMCS in disaster risk management.
