Abstract
The COVID-19 outbreak, although primarily considered a public health crisis, has significantly impacted the labor market. On account of the restrictions imposed, many companies have been forced to cease operations or reduce their activities. In addition to transitioning to remote work, employees often encounter temporary or permanent job loss. The primary objective of this investigation is to examine the spatial configuration exhibited by COVID-19 incidents and the spatial pattern of unemployment, as well as the spatial correlation of COVID-19 with unemployment in East Java Province. In this research, the analytical approach employed involves the utilization of Moran Index analysis. The study results show that the spatial pattern of COVID-19 incidents and the spatial pattern of unemployment in East Java Province are clustered, where districts with an increased number of COVID-19 incidents surround districts with a high number of COVID-19 incidents. Similar to this is the situation with unemployment, where high-unemployment areas surround low-unemployment areas. The results of the spatial relationship between COVID-19 incidents and unemployment show a positive value, which means there is a spatial correlation among the incidence of COVID-19 and unemployment in the districts of East Java Province. The government implements policies relating to lockdowns and similar measures to mitigate the spread and transmission of COVID-19. An effective strategy would involve targeting regions nearby where districts exhibiting a high prevalence of COVID-19 incidents coincide with districts characterized by a heightened concentration of unemployed individuals. Consequently, as the number of COVID-19 incidents diminishes, a corollary reduction in unemployment rates is anticipated, attributable to the resumption of economic activities facilitated by the reopening of businesses.

Published: January 2024

Abstract
Surface wind characteristics are one of the factors in the formation of weather in a place, such as coastal areas that are directly adjacent to the ocean. One of the areas located on the Southern coast of the Java island, is Palabuhanratu, Sukabumi. This study will provide an overview of the characteristics of the diurnal pattern of surface wind in the Palabuhanratu area in the form of bay. The data that will be used in this research is ERA5 global analysis data produced by The European Center for Medium-Range Weather Forecasts (ECMWF) and Observation data. Observational data and ERA5, show different diurnal patterns in each season. This can be seen especially during the day, from 10 to 16 local time. The diurnal pattern of ERA5 also shows different things at the summer (JJA) and during the rainy season (DJF) in Palabuhanratu.

Abstract
In this study, the two-dimensional lattice Boltzmann method was employed to simulate the motions and distributions of a circular squirmer in a linear shear flow. The objective was to systematically investigate the dynamics of microorganisms or engineered squirmers in a flowing environment. We conducted multiple simulations across a range of self-propelled strengths (0.08 ⩽ α ⩽ 0.8) and squirmer type parameters (−5 ⩽ β ⩽ 5). Initially, we analyzed the swimming motions of the neutral squirmer (β = 0) in the shear flow. Our analysis revealed two distinct distributions depending on α, i.e. near the bottom or the top plate, which differs from conventional particle behavior. Moreover, we observed that the separation point of these two distributions occurs at αc
= 0.41. The puller and pusher exhibit similarities and differences, with both showing a periodic oscillation pattern. Additionally, both types reach a steady inclined pattern near the plate, with the distinction that the low-pressure region of the puller’s head is captured by the plate, whereas the pusher is captured by the low-pressure region on the side of the body. The limit cycle pattern (LCP) is unique to the pusher because the response of the pressure distribution around the pusher to the flow field is different from that of a puller. The pusher starts from the initial motion and asymptotes to a closed limit cycle under the influence of flow-solid interaction. The frequency St of LCP is inversely proportional to the amplitude h
* because the pusher takes longer to complete a larger limit cycle. Finally, an open limit cycle is shown, representing a swimming pattern that crosses the width of the channel.
Automated prediction of diabetes mellitus using infrared thermal foot images: recurrent neural network approach
Authors: Gulshan  , Arora Ajat Shatru 
Published: January 2024

Abstract
Millions of people worldwide are affected by Diabetes Mellitus (DM), which is a chronic disease. Evaluation of the DM indicator, namely blood glucose level, requires invasive methods such as glucometer or blood tests, which cause discomfort to the patient. Automated noninvasive monitoring methods are urgently needed to ensure consistency and better treatment. The regular monitoring of DM can prevent or delay the onset of complications. Thermal foot images have been proposed as noninvasive methods for the prediction of DM. Thermograms were acquired at Mittal Eye Hospital, Sangrur, India, from 50 participants in the diabetic (without neuropathic conditions) and non-diabetic groups using a thermal camera (FLIR E-60). This study proposes an automated prediction system for DM using thermal foot images and Recurrent Neural Network (RNN) approach. The proposed system processes the thermal images and extracts relevant features using a CNN (Convolutional Neural Network). The extracted features were then fed to the RNN to predict the presence or absence of the DM. The experimental results demonstrate that the proposed framework attains an accuracy of (97.14 ± 1.5)%, surpassing the predictive capabilities of light-weight convolutional neural network (Lw-CNN), which only achieves an accuracy of (82.9 ± 3) % in predicting DM. This performance outperformed other state-of-the-art methods in the field. Our approach has the potential to be used as prediction tool for DM. Therefore, the proposed system has the potential for prediction of DM and improve patient outcomes by enabling timely intervention. Future work should focus on evaluating the proposed system on a larger dataset and integrating it with clinical decision support systems for personalized care. This study holds the promise of transforming DM screening and diagnosis, leading to enhanced patient outcomes.

Abstract
Engineering materials with highly tunable physical properties in response to external stimuli is a cornerstone strategy for advancing energy technology. Among various approaches, engineering ionic defects and understanding their roles are essential in tailoring emergent material properties and functionalities. Here, we demonstrate an effective approach for creating and controlling ionic defects (oxygen vacancies) in epitaxial Gd-doped CeO2−x
(CGO)(001) films grown on Nb:SrTiO3(001) single crystal. Our results exhibit a significant limitation in the formation of excess oxygen vacancies in the films during high-temperature film growth. However, we have discovered that managing the oxygen vacancies in the epitaxial CGO(001) films is feasible using a two-step film growth process. Subsequently, our findings show that manipulating excess oxygen vacancies is a key to the emergence of giant apparent dielectric permittivity (e.g.

Abstract
Thermal annealing alters the morphology of organic donor-acceptor bulk-heterojunction thin films used in organic solar cells. Here, we studied the influence of thermal annealing on blends of amorphous regio-random (RRa) and semi-crystalline regio-regular (RR) poly (3-hexylthiophene) (P3HT) and the fullerene derivative [6,6]-phenyl-C60-butyric acid methyl ester. Since the P3HT:PCBM blend is one of the most studied in the OPV community, the existing research provides a solid foundation for us to compare and benchmark our innovative characterization techniques that have been previously under-utilized to investigate bulk heterojunction organic thin films. Here, we combine advanced novel microscopies and spectroscopies, including polarized light microscopy, photo-deflection spectroscopy, hyperspectral photoluminescence imaging, and energy resolved-electrochemical impedance spectroscopy, with structural characterization techniques, including grazing-incidence wide-angle x-ray scattering, grazing-incidence x-ray diffraction, and Raman spectroscopy, in order to reveal the impact of thermal annealing on the microstructural crystallinity and morphology of the photoactive layer in organic solar cells. Coupled transfer matrix and drift-diffusion simulations were used to study the impact of the density of states on the solar cells’ device performance parameters, namely the short-circuit current (J
SC), open circuit voltage (V
OC), fill factor (FF), and power conversion efficiency (PCE).

Authors: Sawant Sachin N , Patil Sachin K 
Published: January 2024

Abstract
This study investigates the impact of various machining conditions on the response variables, namely Tool Wear Rate (TWR), Material Removal Rate (MRR), and Hole Taper (HT), during rotary micro-Electrical Discharge Machining (μ-EDM) of Ti-6Al-4V plates with thicknesses of 0.5 mm (W1), 1 mm (W2), and 1.5 mm (W3). Implementing effective flushing techniques and consistent maintenance of machining conditions improved μ-EDM performance, particularly for high aspect ratios. Using a Taguchi-based L9 orthogonal array, experiments were designed and analyzed through Analysis of Variance (ANOVA). The study revealed that capacitance and electrode rotation speed (ERS) significantly contributed to MRR, with capacitance playing a more substantial role. Specifically, for the W3 workpiece, capacitance demonstrated a remarkable MRR of 0.01894 mm3 min−1, 51.12% and 63.10% greater than W1 and W2, respectively. Conversely, W1 exhibited the lowest TWR of 0.000193 mm3 min−1, 50.61% and 67.24% lower than W2 and W3. W1 also improved accuracy by significantly reducing HT compared to W2 and W3. Scanning Electron Microscopy (SEM) analysis explored the effects of voltage, capacitance, ERS, and workpiece thickness on micro-hole surfaces. SEM images revealed the presence of debris and burrs contributing to inaccuracies in micro-hole formation. Despite the challenges, the study emphasizes the importance of optimizing machining parameters for enhanced μ-EDM performance in challenging materials.

Abstract

Objective
Assess the feasibility and concurrent validity of a modified Uniform Data Set version 3 (UDSv3) for remote administration for individuals with normal cognition (NC), mild cognitive impairment (MCI), and early dementia.

Method
Participants (N = 93) (age: 72.8 [8.9] years; education: 15.6 [2.5] years; 72% female; 84% White) were enrolled from the Wake Forest ADRC. Portions of the UDSv3 cognitive battery, plus the Rey Auditory Verbal Learning Test, were completed by telephone or video within ~6 months of participant’s in-person visit. Adaptations for phone administration (e.g., Oral Trails for Trail Making Test [TMT] and Blind Montreal Cognitive Assessment [MoCA] for MoCA) were made. Participants reported on the pleasantness, difficulty, and preference for each modality. Staff provided validity ratings for assessments. Participants’ remote data were adjudicated by cognitive experts blinded to the in person-diagnosis (NC [N = 44], MCI [N = 35], Dementia [N = 11], or other [N = 3]).

Results
Remote assessments were rated as pleasant as in-person assessments by 74% of participants and equally difficult by 75%. Staff validity rating (video = 92%; phone = 87.5%) was good. Concordance between remote/in-person scores was generally moderate to good (r = .3 −.8; p &lt; .05) except for TMT-A/OTMT-A (r = .3; p &gt; .05). Agreement between remote/in-person adjudicated cognitive status was good (k = .61–.64).

Conclusions
We found preliminary evidence that older adults, including those with cognitive impairment, can be assessed remotely using a modified UDSv3 research battery. Adjudication of cognitive status that relies on remotely collected data is comparable to classifications using in-person assessments.
Sports clubs’ role in community capacity development—illustrations from the Swedish sports movement
Authors: Blomqvist Mickelsson Tony 
Published: January 2024

Abstract
Strong political neoliberal currents in Sweden are directing attention toward communities’ responsibility to address local issues, particularly in disadvantaged areas. In parallel, community sports clubs in Sweden have gained strong traction as being sites where social issues can be addressed. In Swedish disadvantaged areas, where infrastructure is of poor quality, these clubs can be an important addition to statutory interventions, but they need to be further explored in terms of strategic pathways and conditions. Community sports have only recently been conceptualized with Chaskin’s capacity-building concept. In this paper, I seek to further stimulate this line of inquiry. By using material from two interrelated projects with informants in the sports movement, I show how sports clubs use multiple strategies according to three of Chaskin’s proposed strategies: leadership development, organizational development, and inter-organizational collaboration. By outlining an empirically dense illustration, this paper contributes to the research on sports clubs and their role in the community and provides suggestions on how strategical assessments must include how associations develop strategies online.
The cellular zeta potential: cell electrophysiology beyond the membrane
Authors: Hughes Michael Pycraft 
Published: January 2024

Abstract
The standard model of the cell membrane potential Vm describes it as arising from diffusion currents across a membrane with a constant electric field, with zero electric field outside the cell membrane. However, the influence of Vm has been shown to extend into the extracellular space where it alters the cell’s ζ-potential, the electrical potential measured a few nm from the cell surface which defines how the cell interacts with charged entities in its environment, including ions, molecules, and other cells. The paradigm arising from surface science is that the ζ-potential arises only from fixed membrane surface charge, and has consequently received little interest. However, if the ζ-potential can mechanistically and dynamically change by alteration of Vm, it allows the cell to dynamically alter cell–cell and cell-molecule interactions and may explain previously unexplained electrophysiological behaviours. Whilst the two potentials Vm and ζ are rarely reported together, they are occasionally described in different studies for the same cell type. By considering published data on these parameters across multiple cell types, as well as incidences of unexplained but seemingly functional Vm changes correlating with changes in cell behaviour, evidence is presented that this may play a functional role in the physiology of red blood cells, macrophages, platelets, sperm, ova, bacteria and cancer. Understanding how these properties will improve understanding of the role of electrical potentials and charges in the regulation of cell function and in the way in which cells interact with their environment.
Insight The zeta (ζ) potential is the electrical potential a few nm beyond the surface of any suspensoid in water. Whilst typically assumed to arise only from fixed charges on the cell surface, recent and historical evidence shows a strong link to the cell’s membrane potential Vm, which the cell can alter mechanistically through the use of ion channels. Whilst these two potentials have rarely been studied simultaneously, this review collates data across multiple studies reporting Vm, ζ-potential, electrical properties of changes in cell behaviour. Collectively, this points to Vm-mediated ζ-potential playing a significant role in the physiology and activity of blood cells, immune response, developmental biology and egg fertilization, and cancer among others.

ABSTRACT

Introduction
Military transport can induce whole-body vibrations, and combat almost always involves high impact between lower extremities and the ground. Therefore, robust splinting technology is necessary for lower extremity fractures in these settings. Our team compared a novel one-step spray-on foam splint (FastCast) to the current military standard structured aluminum malleable (SAM) splint.

Materials and Methods
Ten cadaveric specimens were subjected to complete tibia/fibula osteotomy. Specimens were fitted with custom accelerometer and gyroscope sensors superior and inferior to the fracture line. Each specimen underwent fracture and splinting from a standard of care SAM splint and an experimental FastCast spray foam splint in a randomized order. Each specimen was manually transported to an ambulance and then released from a 1 meter height to simulate impact. The custom sensors recorded accelerations and rotations throughout each event. Repeated-measures Friedman tests were used to assess differences between splint method within each event and between sensors within each splint method.

Results
During splinting, overall summation of change and difference of change between sensors for accelerations and rotations were greater for SAM splints than FastCast across all axes (P ≤ 0.03). During transport, the range of acceleration along the linear superior/inferior axis was greater for SAM splint than FastCast (P = 0.02), as was the range of rotation along the transverse plane (P &lt; 0.01). On impact, the summation of change observed was greater for SAM splint than FastCast with respect to acceleration and rotation on the posterior/anterior and superior/inferior axes (P ≤ 0.03), and the cumulative difference between superior and inferior sensors was greater for SAM than FastCast with respect to anterior-axis rotation (P &lt; 0.05).

Conclusion
FastCast maintains stabilization of fractured lower extremities during transport and impacts to a significantly greater extent than SAM splints. Therefore, FastCast can potentially reduce the risk of fracture complications following physical stressors associated with combat and extraction.
COVID-19 lockdowns weigh heavily on youth: an analysis of the impact on BMI for Age Z scores in children and adolescents

Published: January 2024

Abstract

Background
The COVID-19 pandemic has significantly impacted the lifestyle and health of children and adolescents. This study aimed to assess the lifestyle changes brought about by COVID-19-related school closures and their impact on the Body Mass Index for Age Z (BAZ) scores of governmental school students in Qatar.

Methods
An analytical cross-sectional study was conducted between June and August 2022 targeting students aged 8–15 years. Data on lifestyle behaviors were gathered through telephone interviews with parents of selected students. The BAZ scores before and after school closures that were automatically calculated by the electronic health records system were extracted.

Results
We completed 1546 interviews. We found a significant increase in unhealthy food categories, a reduction in physical activity and an increase in the screen time over the period of schools’ closure. The BAZ increased significantly by 0.30 (95% CI 0.26–0.35). The increase in BAZ scores was significantly higher among male students and the younger age group compared to females and older counterparts, respectively. The student’s age group, sex, nationality and change in physical activity were significant predictors of the change in BAZ scores.

Conclusions
School closures during the COVID-19 pandemic negatively impacted the lifestyle of students in Qatar and resulted in a significant increase in the BAZ scores.
