Published: February 2025

Abstract

The main objective of this research is a numerical investigation of the transport properties in hydrogenated nanocrystalline silicon thin films for solar cells applications using the wxAMPS software tool. The simulated samples were fabricated at 100°C using radiofrequency magnetron sputtering (RFMS) method with RF power 220 W, a gas mixture of 30% of argon and 70% of hydrogen under a total pressure of 3 Pa and the target – sample holder distance, fixed at 70 mm, were maintained constant for the three categories intrinsic, phosphorus doped and boron doped films at deposition times of 3 and 30 minutes. The simulation carried out in this research, is based on a layer of nanocrystalline silicon that was constructed using successive and alternative crystalline and amorphous thin layers where their total number is depending on the thickness of the considered sample. The electronic transport mechanism is studied and findings clearly demonstrated that doped and undoped samples have different activation energy (Ea) which obviously illustrates the crucial role of doping. The Ea is less than 0.2 eV for all the simulated samples strongly indicating a hoping transport mechanism. These results were compared to experimental and previous works where a good agreement was observed.

Authors: Brink Rob F.M. , Boschero Juan C. , Amoretti Michele 
Published: February 2025

Abstract

We propose a layer model to specify functionality and interfacing for hardware and software modules, to enable modular quantum computers. The group of lower layers covers multiple stacks, one for each hardware architecture, while the upper layers are defined around a common software stack. A hardware abstraction layer connects the two. The addition of a separate communication unit offers a robust separation between the stack and the outside world, and allows controlled access for multiple users as well as for being a server to hybrid computing systems.

Published: February 2025

Abstract

The Clinical Placement Quality Survey – Student (CPQS-S) was developed to capture allied health students' perceptions of placement quality, in alignment with the Best Practice Clinical Learning Environment framework. This study aimed to validate the CPQS-S using Rasch Analysis across multiple allied health disciplines, encompassing students from Clinical Exercise Physiology, Exercise Science, Nutrition and Dietetics, Occupational Therapy, Physiotherapy, Rehabilitation Counselling, Social Work, and Speech Pathology programs. Data collected from 933 students were divided into development and validation samples. The CPQS-S was confirmed to be measuring a unidimensional construct and Rasch Analysis showed that items demonstrated strong fit statistics and separation reliability, affirming the tool’s psychometric robustness in measuring student perceptions. These findings support the CPQS-S as a reliable, data-driven instrument that consistently assesses placement experiences across diverse settings. The validated structure underscores the CPQS-S as a reliable instrument for assessing and benchmarking placement quality, providing educators with actionable data to enhance clinical learning environments. More broadly, these findings contribute to the advancement of work-integrated learning research by offering a validated tool to inform educational interventions and quality improvement initiatives in health professions education.

Authors: Zhang Hong , Zhang Sai , Zhou Miao , Geng Chunmi , Ding Xiang 
Published: February 2025

Abstract

Background
Anxiety and depression are highly prevalent and disabling mental disorders that often coexist. Kidney transplant recipients are at high risk of anxiety and depression, especially during the COVID-19 pandemic. However, studies focusing on depression and anxiety among kidney transplant recipients in the post-COVID-19 era are lacking.
Objective
This study aimed to analyze the prevalence and risk factors associated with anxiety symptoms alone (ASA), depressive symptoms alone (DSA), and comorbid anxiety and depressive symptoms (CADS) in kidney transplant recipients after the COVID-19 pandemic.
Methods
A cross-sectional survey was conducted among kidney transplant recipients in a tertiary hospital in Hunan, China, from December 2022 to December 2023. Anxiety and depressive symptoms were assessed using the Self-Rating Anxiety Scale (SAS) and Self-Rating Depression Scale (SDS), based on which participants were divided into four groups: normal (no anxiety or depressive symptoms), ASA, DSA, and CADS. Clinical characteristics were compared between the groups, and the risk factors associated with ASA, DSA, and CADS were analyzed using multiple logistic regression.
Results
A total of 517 kidney transplant recipients were enrolled in this study, and 321 (62.1%) had neither anxiety nor depression symptoms. ASA was identified in 3.7% of recipients (n = 19), DSA in 20.3% (n = 105), and CADS in 13.9% (n = 72). Multiple logistic regression showed that rejection was positively associated with ASA, and vaccination was negatively associated with DSA. Younger age, transplant nephritis/nephropathy, a history of postoperative pulmonary infection, and rejection were positively associated with CADS.
Conclusion
In the post-COVID-19 era, anxiety and depressive symptoms remain prevalent among kidney transplant recipients and are associated with various factors. Our findings provide helpful guidance to develop targeted and effective interventions based on anxiety and depressive status to improve their mental health.
Evaluating the impact of different decomposition methods on the accuracy of reference evapotranspiration forecasts in humid regions
Authors: Yan Zihuang , Lu Xianghui , Wu Lifeng 
Published: February 2025

ABSTRACT

The forecasting of reference crop evapotranspiration (ET0) plays a crucial role in irrigation scheduling. In this study, we employed deep learning (DL) models, including convolutional neural network (CNN), long short-term memory (LSTM), bidirectional LSTM (Bi-LSTM), CNN-LSTM, and CNN-Bi-LSTM, to forecast ET0 at three different stations (Nanchang, Xinjian, and Dongxiang) in Jiangxi Province, China, for various forecast lead times (1, 3, 5, 7, 10, and 15 days). The experimental results demonstrate that LSTM and Bi-LSTM achieved the highest predictive accuracy across the three stations, with corresponding average values of coefficient of determination (R²), mean absolute error (MAE), root mean square error (RMSE), Nash–Sutcliffe efficiency (NSE), and combined accuracy (CA) of 0.9646, 0.2456 mm day−1, 0.2931 mm day−1, 0.9646, and 0.2043, respectively. Compared with the baseline model, the hybrid models incorporating complete ensemble empirical mode decomposition with adaptive noise (CEEMDAN), EEMD, and CEEMD exhibited inferior predictive performance. Additionally, their significantly longer runtime resulted in operational costs that were 8–10 times higher. In contrast, DL-based LSTM and Bi-LSTM are excellent algorithms for forecasting ET0 across various time intervals.
Application of the RUSLE model to estimate sedimentation in the Lwanyo Reservoir in Mbarali District Mbeya – Tanzania
Authors: Moshi Baraka Moses , Katambara Zacharia , Lingwanda Mwajuma 
Published: February 2025

ABSTRACT

The constant increase in the global population is proportional to the increase in human basic needs, which are associated with environmental degradation. The impact of sedimentation in water bodies poses social and economic challenges as it lessens the storage capacities. The RUSLE model expresses the effect of sedimentation in the Lwanyo reservoir sub-catchment. The maximum erosivity factor (R) is 421.39 (MJ mm ha−1 h−1 yr), the soil erodibility factor (K) is 0.071, the topographic factor (LS) due to catchment topography is 9.086, the vegetation cover and management factor (C) is 0.1045, and the conservation practice factor (P) is 0.14 f. The RUSLE model estimates soil sediment loss to be 3.977 tonnes/ha/year as the average annual soil loss for the Lwanyo sub-catchment area is 39.6 km2. This value indicates that for every hectare, the average annual soil loss is 1.004 × 10−3 tonnes/year, with silt as the dominant soil sediment being eroded. When anteversion measures are not taken, it is estimated that after 30 years, the sediment load will be 119.31 tonnes, which will reduce the storage capacity by 68.177 m3. Reducing catchment anthropogenic activities and practising catchment afforestation will increase the soil mass compatibility, hence lowering the soil loss effect and the sedimentation effect.
The Apoptotic and Antioxidant Effects of Capsaicin on Colorectal Cancer Cell Lines
Authors: Hormozi Maryam , Baharvand Parastoo 
Published: February 2025

Background
Capsaicin is a natural alkaloid and one of the main active components found in spicy peppers, responsible for their hot taste. It possesses antioxidant and anti-tumor properties.
In this study, the effect of capsaicin on the expression of genes involved in apoptosis, such as Bax, Bcl2, Caspase3, p53, PPARγ, Nrf2, and the activity of antioxidant enzymes, including superoxide dismutase, catalase, and glutathione peroxidase, was investigated in LS-180 and HCT-116 human colorectal cancer cell lines.

Methods
Human colorectal cancer cell lines (LS-180 and HCT-116) were treated with various concentrations of capsaicin for 24 hours. The expression levels of genes, including Bax, Bcl2, Caspase3, Nrf2, PPARγ, and p53, were determined using the Real-time PCR method, and the activity of antioxidant enzymes was measured using colorimetric assays.

Results
Analysis of gene expression results showed that capsaicin increased the expression levels of Bax, Bcl2, Caspase3, and p53 in both cell lines, but this increase was statistically significant in the LS-180 cell line. Capsaicin also significantly increased the expression of Nrf2 and PPARγ in both cell lines. The activity of antioxidant enzymes, including superoxide dismutase, catalase, and glutathione peroxidase, was increased in both cell lines compared to the control.

Conclusion
It appears that capsaicin may play a role in inducing apoptosis and reducing the proliferation of colorectal cancer cells through the upregulation of Nrf2, PPARγ, and p53 gene expression and the increase in antioxidant enzyme activity. Additionally, the upregulation of Bax and Caspase 3 expression suggests a potential mechanism for capsaicin-induced apoptosis and the reduction of colorectal cancer cell growth.

The aim of the study was to search for candidate genes interacting with HIV attachment receptors (CCR5, CXCR4, CCR2, CD4) and potentially involved in disease pathogenesis, based on complex in silico network algorithms.Materials and methods. A number of web applications were used to analyse genetic and protein-protein networks, the algorithms and databases of which are complementary. The CD4 receptor and chemokine co-receptor genes CCR5, CXCR4 and CCR2 were used as background/baseline genes in all cases, as their protein products play a key role in the process of virus attachment to the cell. The data were analysed, including a two-stage ranking of the identified candidate genes according to their interaction with background genes and their presence in the results of network analysis of different web resources.Results and discussion. According to the results, candidate genes were identified using three web resources: HumanNet — 451 candidate genes, GeneMania — 86, STRING — 61. Based on the results of crossing the three web resources, the total number of candidate genes associated with background genes was 511. The total number of genes with a rank above 4 points was 68. Of these, 31 genes (45.6%) encoding C-C/C-X-C family chemokine ligands, 12 genes (17.6%) encoding C-C/C-XC receptors, 8 genes (11.8%) encoding receptors of other types, and 17 genes (25%) encoding proteins of other types. The following receptors and proteins that are not members of the C-C/C/C-X-C families of the indicated groups have been identified: ARRB2, TLR2, ADRA1A, ARRB1, FPR1, FPR3, GNAI1, PF4, PIK3CG, PPIA, S1PR3, GNA11, GNAI2, GNG2, PTPRC, ADRA1B, ADRB1, AFP, CD164, DBN1, GNB1, ITCH, RNF113A, SLC1A1, USP14.Conclusion. Most of the identified candidate genes interacting with HIV attachment receptors and potentially involved in the pathogenesis of the disease were those encoding chemokine receptors and their C-C/C-X-C family ligands, the role of which in the progression of HIV infection is known or under active investigation. At the same time, genes whose products have never been considered as possible participants in the pathogenesis of the disease were identified, but the results suggest that they may play a role in the regulation of virus entry and/or in the modulation of the immune response of the organism. Further bioinformatic and experimental studies of the functions and polymorphic variants of these genes will help to improve the understanding of the genetic basis of HIV pathogenesis and identify new directions for therapeutic approaches.

Abstract
This study investigated the adsorption and desorption performances of water hyacinth leaves powder (WHLP) and water hyacinth roots powder (WHRP) towards Pb2+, Co2+, Zn2+ and Ni2+ in industrial wastewater. The parameters influencing the process were assessed, models were proposed to explain the both the equilibrium and kinetics of the sorption process and desorption study was conducted using different HNO3 and NaOH concentration. The results showed that comparatively, the metal uptake capacity of water WHLP was higher than WHRP as examined by the investigated parameters. The biosorption data fitted to both Langmuir and Freundlich isotherms. The kinetics of the process follows a pseudo-second order reaction model because it provides good linearization of the experimental data. In addition, relatively successful metal ions desorption from the biosorbents were recorded with both NaOH and HNO3 solutions.
