A new class of functions is defined by expressing analytic characterizations of starlike function involving logarithm. To make this study more versatile, we redefine and study the class involving an operator associated with -hypergeometric function. Estimates of the initial coefficients and Fekete-Szegő inequality of the functions, which belong to the defined function class, are our main results.

This study introduces the Geographically Weighted Weibull Regression (GWWR) model as an extension of the Weibull regression (WR) within the geographically weighted regression framework and applies it to spatial environmental data on dissolved oxygen (DO) levels in East Kalimantan in 2024, rather than to time-to-event data. This study maps the river water quality (RWQ) and its influencing factors using the GWWR model. The results indicate that the RWQ in East Kalimantan in 2024 generally tends to degrade, with the main influencing factors being dissolved iron, total phosphate, water temperature, and biochemical oxygen demand. The main highlights of the proposed method are as follows:
•
This study presents the GWWR model as an extension of the WR model and demonstrates its applicability to spatially heterogeneous data rather than to time-to-event data.
•
The GWWR model is employed to locally analyze RWQ and its influencing factors.
•
The GWWR approach represents RWQ characteristics using several statistical measures, including the probability of water quality improvement, the probability of water quality degradation, the water quality degradation rate, and the mean DO level. These statistical measures are analyzed respectively through spatial Weibull survival, cumulative distribution, hazard, and mean regression models.

While academic literature offers various models of tourism competitiveness, their specific application to sports tourism in the unique contexts of developing nations remains fragmented and under-theorized, with no prior systematic mapping of evidence from these settings. This scoping review protocol outlines a systematic methodology to comprehensively map and synthesize the existing literature on the competitiveness of sports tourism destinations, with a specific focus on evidence from developing countries. The primary research question is: What are the key determinants and conceptualizations of competitiveness for sports tourism destinations in developing countries? Guided by the Joanna Briggs Institute (JBI) Scoping Review Framework and reported per PRISMA-ScR guidelines, the review will employ inclusive eligibility criteria (Population: sports tourism destinations; Concept: competitiveness factors; Context: developing countries), search academic and grey literature sources, extract data on definitions, determinants, models, challenges, strategies, and evidence, and conduct inductive thematic analysis to identify patterns and gaps. The findings aim to consolidate existing knowledge, identify key determinants and gaps, and establish a foundational understanding to guide future research, policy formulation, and industry practices in the sports tourism domain, particularly for resource-constrained settings.

Optical Genome Mapping (OGM) is an emerging technology in clinical laboratories for identifying copy number and structural variations in the DNA of patients with haematological malignancies. A critical initial step is the isolation of ultra-high molecular weight genomic DNA (UHMW gDNA), which typically requires 1.5 million white blood cells. However, this cell number is not always achievable in clinical practice due to various limitations. For instance, diagnostic analysis of multiple myeloma (MM) is should be performed on CD138-positive cells derived from bone marrow aspirates (BMA), where both the sample volume and the number of CD138-positive cells This method describes a customized protocol which enables isolation of UHMW gDNA starting from as few as 500 000 cells, while still resulting in DNA of sufficient quality and quantity to perform OGM and collect at least 1500 Gbp of data.

Depression affects over 280 million people worldwide, with neurological patients particularly prone to medication-induced episodes. Conventional diagnostic approaches rely on subjective evaluations, limiting reproducibility and consistency in clinical settings. This study proposes an interpretable deep learning framework for objective depression detection using EEG signals. We hypothesize that combining EEG-based features with explainable artificial intelligence can provide both high accuracy and transparency in diagnosis. The model was trained on EEG data from 232 neurological patients, achieving 98 % classification accuracy. Interpretability was enhanced through SHAP (SHapley Additive exPlanations) analysis, which identified clinically meaningful EEG biomarkers such as the delta/alpha ratio and theta band power. This paper highlights the following contributions: Integration of EEG features with a lightweight deep learning model for depression detection High diagnostic accuracy achieved while maintaining interpretability for clinicians An objective tool that is compatible with existing EEG infrastructure, supporting clinical adoption These results show that our framework bridges predictive performance with interpretability, offering a transparent and scalable EEG-based diagnostic tool. We conclude that this approach can complement clinical decision-making, reducing dependence on subjective evaluation and enabling more consistent, data-driven mental health care.

Image Captioning is a crucial task that enables systems to generate descriptive sentences for visual content. Though image captioning systems bloom at the intersection of Computer Vision and Natural Language Processing, these models act mostly as black boxes offering little or no insight into how captions are derived. We present a novel explainable image captioning framework that integrates a Convolutional Neural Network encoder with a Transformer decoder. Attention-based heatmaps are used to explain the visuals offering transparency in the decision making process. The method evaluates captioning quality and interpretability on the MS COCO dataset using BLEU, METEOR, CIDER and SPICE. The method enhances the trustworthiness and transparency, making it reliable for applications like healthcare, education, security, surveillance and forecasting. A reproducible method for integrating visual explainability into image captioning exploring transformer decoder attention maps. The method contributes to the growing body of eXplainable AI (XAI) by addressing the transparency gap in vision-language models Balance performance with interpretability paving the way for more transparent and trustworthy AI systems.

Motivation
Profiling the T cell receptor (TCR) repertoire using next-generation sequencing (NGS) to quantify adaptive immune responses has become common in human and animal research. Companion dogs with spontaneous tumors have similarities with humans who have cancer. T cells undergo clonal expansion when they recognize specific antigens via surface TCRs. TCR counts from NGS data provide a way to quantify T cell response to vaccines, cancer, or infectious diseases for preclinical and clinical health studies. One complication is that the power and accuracy of TCR experiments depend substantially on the TCR sequencing depth, therefore it is important to determine the optimal read depth of an experiment to verify whether a subject’s repertoire is correctly represented.
Results
The optimal TCR sequencing depth for future experiments can be determined by randomly sampling lower TCR sequencing depths from a sequencing experiment, assembling the TCR clonotypes, and determining where the saturation of power and accuracy occurs. Moreover, one can determine whether an existing experiment has sufficient sequencing depth to justify its conclusions. We provide guidelines to determine whether the sequencing depth is adequate and a computational pipeline that:

Antiepileptic drugs are considered contaminants of emerging concern in water and are resistant to conventional wastewater treatment processes. Therefore, their presence has been detected in surface waters, and their elimination/degradation requires effective treatment methods. In this research, ultrasound-based methods (e.g., sonolysis, sono-Fenton, and sono-photo-Fenton) were addressed in the degradation of antiepileptic drug primidone at laboratory scale. A high-frequency ultrasound (at 578 kHz and 20.4 W) was applied. Then, Fe2+ ions (5 mg l-1) and a UVA lamp (4 W) were added to the sonochemical reactor. After 75 min of treatment, the sono-photo-Fenton method showed better degradation efficiency (93 %) than the sono-Fenton (83 %) and sonolysis (62 %) methods. Finally, the effectiveness of the degradation method by sono-photo-Fenton was tested in simulated pharmaceutical wastewater, degrading 72 % of primidone at 75 min of treatment, indicating matrix effect plays a role in the degradation (which could be a potential application of ultrasound hybridized with the photo-Fenton process).•Three ultrasound-based treatment methods were applied to degrade primidone in water.•The sono-photo-Fenton method degraded 93 % of primidone during 75 min of treatment.•The matrix influence on primidone degradation by sono-photo-Fenton was evaluated.

Monopiles are a widely-used foundation system for offshore wind turbine support structures. In current practice, design calculations typically employ one-dimensional (1D) models in which the monopile is represented as an embedded beam. The current study presents a data-driven 1D design model for the analysis of offshore monopiles subjected to monotonic lateral load and moment loading. The method is based on the PISA design model framework; enhancements are incorporated in the model to improve its accuracy, scalability and to facilitate applications to a wide range of geotechnical conditions. The data-driven model incorporates a spline-based parametrisation of the soil reaction curves combined with machine learning techniques. The model is calibrated using a database of previously-published three-dimensional finite element calibration analyses. The method described in the current paper is concerned with:
•
Modifications to the PISA design model framework to develop a data-driven 1D design model.
•
Calibration of the data-driven 1D model for ground conditions comprising: (i) offshore glacial tills with varying strength–stiffness properties, and (ii) sands with a wide range of relative densities.
•
Validation of the proposed method by comparing 1D model predictions for monopiles in homogeneous and layered soils with detailed 3D finite element analyses.

This article presents the development of LOSARI, a novel R-based statistical software designed to facilitate students' self-regulated learning (SRL) in statistics courses. LOSARI can be accessed online without installation and allows students to perform statistical analyses through a point-and-click interface without coding. It integrates several innovative features: interactive video tutorials embedded in the analysis environment, real-time error notifications that guide students in correcting mistakes, and automatic interpretation of results to support independent learning. The software was validated through a student satisfaction survey using the End-User Computing Satisfaction (EUCS) model, which indicated that most users had positive perceptions of LOSARI and found it effective for learning statistics outside the classroom.

LOSARI can be accessed online without installation and allows students to perform statistical analyses through a point-and-click interface without coding. It integrates several innovative features: interactive video tutorials embedded in the analysis environment, real-time error notifications that guide students in correcting mistakes, and automatic interpretation of results to support independent learning. The software was validated through a student satisfaction survey using the End-User Computing Satisfaction (EUCS) model, which indicated that most users had positive perceptions of LOSARI and found it effective for learning statistics outside the classroom.
