Abstract
Background Working in an operating room (OR) is physically and mentally challenging: the operation itself demands the surgeon’s full attention, while owing to time and cost efficiency constraints daily planning and emergency care keep interfering on different levels. Thus, multitasking becomes an integral surgical competence. This study aims to examine the effect of disruptions during surgery in highly immersive virtual reality (IVR) operation environment combined with a VR laparoscopy simulator.Methods An IVR environment was created using a high resolution, stereoscopic 360° video of the OR. Different distractions were identified, classified as auditory, visual or audio-visual and recorded accordingly. The surrounding was combined with a VR laparoscopic simulator. Participants - medical students and surgical residents - receive proficiency-based training in basic laparoscopic skills and are blinded to the aim of the experiment. Following a cross-over design, each participant receives a unique order of virtual distraction factors while performing tasks on the laparoscopic simulator. During the experiment, subjective passing of time, stress, heart rate and visually induced motion sickness are recorded. After the experiment, validated questionnaires for usability, immersion and stress are completed, as well as subjective evaluation of the distractions. Performance in the laparoscopic tasks in relation to the distractions will be evaluated. Subgroup analyses in regard of age, gender and expertise (medical students vs. surgical residents) are planned.Discussion We present a protocol for a study aiming to identify the impact of different disruptions in the OR during laparoscopic training in immersive VR. Hence, it may lead to an improved awareness of distractions and facilitate accommodations towards an improved work environment. Prior research leads to the hypothesis that the performance of a more experienced surgeon is less impacted by distractions, than the performance of inexperienced surgeons and medical students. Furthermore, we investigate which type of distraction has the largest impact on performance. With this knowledge, specific multitasking training can be devised, which may be particularly useful in medical education, for which VR might play a leading role.Trial registration This trial has been prospectively registered in the German Clinical Trials register with the registration number DRKS 00030033, registration confirmed 18th of August 2022, https://www.drks.de/drks_web/

Abstract

Traditional teaching methods that use 2D videos or 3D simulators may have limitations in engineering education when covering complex concepts or complicated 3D structures. To address this problem, virtual reality (VR) has been introduced as a highly immersive teaching method that can increase students’ learning and understanding of 3D structures from multiple perspectives. The purpose of this study was to quantify how teaching methods that use VR can increase learning efficiency and comprehension of 3D structures. We used quiz and 3D reconstruction to assess the quantitative learning effects of VR and 2D videos on a total of 40 students. Training that used VR yielded a 12% improvement in post-test quiz scores and a 13% improvement in 3D reconstruction test scores compared to the traditional method. User evaluations confirmed that VR increased engagement by 11.9%, immersion by 18.6%, motivation by 10.3%, cognitive benefits by 9.3%, and perceived learning effectiveness by 8.7%. These results confirm that VR is more effective than traditional learning methods to aid general memorization and understanding, and specific comprehension of 3D structures.
Evaluation of approaches to internal validation of multinomial Logit models: the case of personal travel mode choice
Authors: Parmar Janak , Site Paolo Delle 
Published: October 2023

Abstract

The prediction validity of discrete choice models is key for policy making in the transportation sector. For internal validation, i.e., when the population used to estimate and validate the model is the same, different approaches exist. Each approach is characterised in terms of sampling strategy and accuracy metric. The former includes in-sample, also referred to as apparent, split-sample, cross-validation, and bootstrapping. The latter include McFadden rho-squared, percentage of right classification, McFadden proportion of right predictions, Brier Score, polytomous discrimination index, and hypervolume under ROC manifold. It is widely recognised that in-sample strategies are overly optimistic, because the model is optimized for performance in the sample in which it is estimated. Evaluation of performance of approaches to internal validation has been carried out in the clinical epidemiology area with logistic regression models. This paper evaluates approaches to internal validation using synthetic and real datasets related to personal travel mode choices modelled using multinomial Logit. The performance of each approach is evaluated against the apparent performance in the full population. With both synthetic and real data, cross-validation produces the lowest bias with most metrics. The metric with lowest bias is data-specific. Lowest variability is produced by bootstrapping.

Abstract
Cyberbullying victimization is becoming more prevalent and adversely affects mental health. It is essential to explore the relationship between the two variables and the underlying mechanism, especially for children, as the impact of mental health in childhood might last a lifetime. Thus, the current research focused on the relationship and the underlying mechanism. Primary school students (N = 344; Mage = 9.90; 43.90% girls) completed self-report questionnaires regarding cyberbullying victimization, self-perceived social competence, optimism, and depression at school. Gender and grade were controlled as covariates. Depression was positively predicted by cyberbullying victimization. Besides, self-perceived social competence played a partially mediating role. In addition, optimism directly and indirectly moderated the effects of cyberbullying victimization on depression. Specifically, the effects were stronger for children with low levels of optimism. Therefore, efforts to enhance children's self-perceived social competence and optimism may beneficial to reduce children’s depression resulted by cyberbullying victimization.

Abstract
This research paper utilizes the RUSLE Model to assess soil erosion risk regions within a sub-watershed and classify the entire area based on erosion rate severity. The study was conducted in a sub-watershed of the Karuvannur river basin located in the Thrissur district of Kerala, India. The RUSLE soil erosion model is employed to estimate the annual soil loss values and evaluate the severity of soil erosion. The ArcGIS software is utilized to apply the RUSLE variables, including the Rainfall erosivity factor (R), Soil erodibility factor (K), Slope length steepness factor (LS), Cover management factor (C), and Practice factor (P), for soil erosion estimation. Subsequently, the soil erosion risk map is generated within the ArcGIS environment by analysing the RUSLE parameters R, K, LS, C, and P. Conversion of the maps to raster format using a raster calculator allows for the merging of maps to create the soil erosion model. The soil loss values within the Kurumali watershed range from 0 to 70.26 t h − 1 y − 1, with an average estimated soil erosion rate between 0 to 1 t h − 1 y − 1 and a standard deviation of 1.24.

Abstract

Currently, the preparation of many ORR catalysts is intricate and difficult to control, or they lack stability in reaction, leading to increased costs for practical applications. In this paper, the commonly used carbon supports are combined with conductive PANI to facilely synthesized Pt-based catalysts, ensuring the stability of the catalyst. Experiments explicitly reveal the ORR activity of 40Pt/PANI-Carbon supports catalysts are enhanced signiﬁcantly in comparison to the Commercial 40Pt/C-JM catalyst. Especially, ECSA of 40Pt/PANI-GO (194.4m2gPt-1) is 4.88 times than that of 40Pt/C-JM. Moreover, the integrated area of hydrogen adsorption almost keep constant after ADT, whereas that of 40Pt/C-JM reduced very significantly. Furthermore, the single cell tests definitely confirming the superiority of 40Pt/PANI-GO in activity, which the maximum power output was 2.2 times better than that of the 40Pt/C-JM catalyst. This indicates its broad application prospects and suitability for further exploration in PEMFC.

Abstract
The COVID-19 pandemic and associated countermeasures had an immensely disruptive impact on people’s lives. Due to the lack of systematic pre-pandemic data, however, it is still unclear how individuals’ psychosocial health has been affected across this incisive event. In this study, we analyze longitudinal data from two healthy samples (N = 307) to provide insight into the full trajectory of psychosocial burden before (baseline), during the first peak, and at a relative downturn of the COVID-19 pandemic. Our data indicated a medium rise in psychosocial strain from baseline to the first peak of the pandemic (d = 0.40). Surprisingly, this was overcompensated by a large decrease of perceived burden until downturn (d = − 0.93), resulting in a positive overall effect of the COVID-19 pandemic on mental health (d = 0.44). Accounting for this paradoxical positive effect, our results reveal that the postpandemic increase in mental health is driven by individuals that were already facing psychosocial challenges before the pandemic. These findings suggest that coping with acute challenges such as the COVID-19 pandemic can stabilize previously impaired mental health through reframing processes.

Abstract
Background: This study aimed to evaluate the efficacy and safety concerns of remdesivir and type 1 interferons (INFs) on the clinical outcomes of multiple sclerosis (MS) patients who were hospitalized with COVID-19.
Methods: Using electronic health records systems, this is a cross-sectional study of two years of hospital admissions in terms of COVID-19 in Iran from March 2019 to August 2021. The severities of COVID-19 outcomes were ICU admission, hospitalization days, and 30-day mortality rates.
Results: Nine hundred ninety-nine hospitalized MS patients with a definite diagnosis of COVID-19 based on PCR were recorded in the electronic health systems. Almost half of the patients were under treatment with an anti-CD-20 agent (rituximab or ocrelizumab) at the time of hospital admission (50.3%), with higher mortality rates, needing ICU admission, and longer hospitalization (p<0.05).
There was a significant association between taking IFN alone (adjusted IRR=1.21, 95% CI 1.32 to 1.42) or in combination with RDV (adjusted IRR=1.30, 95% CI 1.18 to 1.5042) and longer hospitalization.
There were no significant associations between antiviral treatment (RDV alone, IFNβ1 alone, and IFNβ1 plus RDV) and ICU admission (p>0.2), in-hospital mortality rate (p>0.2), or 30-day survival rate (p>0.2). The results were similar in patients who did or did not receive anti-CD-20 agents.
Conclusion: Our data reveal that RDV, IFN, or a combination of IFN and RDV administration has no benefit in the treatment of hospitalized MS patients with COVID-19.

Navigating the stages of objective memory impairment (SOMI) through the Papez circuit: hippocampal brain reserve, white matter microstructure, and structural network topology along the Alzheimer’s continuum
Authors: Matziorinis Anna Maria , Leemans Alexander , Skouras Stavros , Koelsch Stefan 
Published: October 2023

Abstract
Background: Alzheimer's disease (AD) unfolds across a spectrum of neurodegeneration, known as the AD continuum, starting several decades before presenting clinical symptoms. The Stages of Objective Memory Impairment (SOMI) is a method used to classify cognitive decline, ranging from negligible impairment to levels indicative of dementia. Identifying individuals at risk for developing AD dementia is crucial for early intervention and potential prevention of cognitive decline.
Aim:This study uses SOMI staging to correlate neural indicators of neurodegeneration by analyzing neuropsychological tests and hippocampal-based brain reserve. We novelly assessed the link between SOMI staging and diffusion-based white matter microstructure metrics and network analytic graph theoretical metrics to examine topological network alterations across the AD continuum.
Methods: 91 participants from the Alzheimer's and music therapy (ALMUTH) study were categorized from SOMI stages 0 through 4. Region-of-interest analyses focused on the Papez circuit, a limbic circuit focused on cognitive processing linked to AD-related neurodegeneration. SOMI stages were associated with neuropsychological measurements, hippocampal-based brain reserve using volumetric analysis, white matter microstructure (fractional anisotropy, FA, and mean diffusivity, MD) in the Papez circuit, and structural network analyses.
Results: SOMI stages significantly correlated with most neuropsychological measures, hippocampal-based brain reserve, FA and MD differences across the Papez circuit, and altered network topological features locally and globally.
Conclusion:Our findings offer new insights into early and progressive alterations of brain function associated with cognitive processing in AD, emphasizing the potential utility of translating these neural indicators for identifying at-risk individuals using non-invasive SOMI staging methods as aids in developing targeted interventions to slow or prevent disease progression.

Effects of Innovative Reinforced Concrete Slit Shaft Configuration on Seismic Performance of Elevated Water Tanks
Authors: Gurkalo Filip , Poutos Konstantinos , He Na 
Published: October 2023

Abstract
Elevated water tanks are considered crucial infrastructure due to their significant role in supporting essential services. A strong ground motion may result in a failure or significant damage to a reinforced concrete shaft of an elevated water tank because a formation of plastic hinges is limited to the base of the shaft, while the nonlinear properties of the rest of the shaft remain underutilised. A modification was made to a reinforced concrete shaft to enhance the seismic resistance of elevated water tanks by introducing slit zones at regular intervals that partitioned the shaft into four segments interconnected by foundation and short linked beams positioned at 5 m intervals. The slit zones were intended to increase the shaft's ductility, reduce stress concentration in the lower part of the shaft, and provide uniform stress distribution throughout the shaft's height. The comparative nonlinear dynamic study between several three-dimensional models of elevated water tanks with slit and solid reinforced concrete shafts was conducted using SAP2000 software. The research findings showed that during a seismic event, reinforced concrete shafts with slits significantly reduce seismic response values at the shaft's base of elevated water tanks with tall and slender shafts compared to short and broad shafts.
Nano- based composite - A successful treatment and preventive measure for coccidiosis in chickens

Published: October 2023

Abstract
The parasitic Eimeria species are very harmful to chickens. The chicken sector suffers enormous financial losses as a result of these parasites, primarily due to reduced production efficiency and increased control costs. Clinical coccidiosis is caused by high levels of Eimeriainfection, which is a serious hazard to chicken welfare and a contributing factor in necrotic enteritis. Controlling Eimeria parasites and coccidiosis is thus a critical endeavor; several methods have been developed, and they are frequently used in tandem. Because of their enormous surface area to volume ratio and rapid absorption in the body, nanoparticles can be introduced to feed and provide a good platform for incorporating in diverse chemicals, such as vitamin supplements. We investigate the current state of formula product utilization as a chicken feed additive, as well as the benefits and drawbacks of nano-feed. The major goal of this experiment is to examine whether the attack of cecal coccidia (E. tenella) isolated in the wild in Taiwan has been prevented by adding the nano silica composite as additives into the daily edible feed and drinking water of chickens, as described in the experimental design. The prevention and treatment outcomes will serve as a resource for relevant practitioners.

Abstract
Background
Online physical training programs emerged as an innovative approach to avoid the detraining-induced physical fitness impairments during the COVID-19 quarantine period in athletes. However, there is conflicting evidence on the effectiveness of such training programs in soccer players.
Aim
This study aimed to verify the effects of a 15-week online training intervention during a pandemic quarantine in body composition and physical capacity of highly trained soccer players.
Methods
Sixteen male under-20 soccer players were assessed after the first period of COVID-19 quarantine (March 2020 to September 2020; 170 days), and after the second period of COVID-19 quarantine (November 2020 to February 2021, 107 days). Body composition, vertical jump height, hamstring maximum strength and aerobic capacity were assessed. The online training program was performed during the second lockdown.
Results
In comparison with first pre assessments, results showed that fat mass (-0.95 ± 1.27), free fat mass (1.22 ± 1.19), squat jump height (5.36 ± 1.99) and counter movement jump (3.19 ± 3.77) were significantly improved (p < 0.05). However, there were no significant changes in total body mass, hamstring eccentric strength, and Yo-Yo IR1 after online training (p > 0.05).
Conclusion
In summary, the findings of this study highlight the importance of carrying out an online training program during a period of absence from traditional soccer training, in order to maintain the level of physical capacities of youth soccer players.
