Nyctophy is a serious game combining virtual reality (VR) and smartwatch integration for nyctophobia (fear of darkness) therapy. The paper thoroughly explores its development framework, simulating dark environments with real-time heart rate monitoring and adaptive flashlight mechanics. Built in Unity Engine, Nyctophy supports VR (Meta Quest 2) and keyboard–mouse interfaces. Performance tests achieved 71.9 FPS (”good” quality) across four devices. Tests with 34 participants revealed longer VR completion times (8:12 min) versus keyboard–mouse (3:54), highlighting immersive impact. Nyctophy demonstrates potential as a safe, innovative tool for diagnosing and treating nyctophobia, leveraging serious games to enhance accessibility and therapeutic outcomes.

GD4Shapes: Geodesic distance with fixed parameterization for 2D Shapes GD4Shapes: 2D形状的固定参数化测地线距离
IF 1.3 Q3 COMPUTER SCIENCE, SOFTWARE ENGINEERING Pub Date : 2025-07-01 Epub Date: 2025-06-10 DOI: 10.1016/j.simpa.2025.100775

Shape analysis within shape space provides a robust framework for examining geometric properties of objects, enabling comparisons invariant to translation, rotation, and scaling. A key task is computing geodesic distances between shapes, which quantify similarity but are computationally intensive due to the need for exhaustive parameterization searches. Recent advancements propose heuristic methods to simplify these computations, such as fixing parameterizations based on the major axis of shapes, significantly reducing computational costs while maintaining high accuracy (e.g., 96.03% in erythrocyte classification). This article introduces a software tool that leverages this heuristic to efficiently compute shape-space distances, aligning shapes considering their major axis, and using templates like circles and ellipses. The tool accelerates morphological analysis, making it ideal for high performance applications in fields like biology and medicine. By streamlining the computation of geodesic distances between shapes and enabling rapid retrieval of information, this software improves research workflows and supports the study of shape-dependent features in diverse fields from cellular morphology to diagnostic hematology.
形状空间中的形状分析为检查对象的几何属性提供了一个健壮的框架,使比较不受平移、旋转和缩放的影响。一项关键任务是计算形状之间的测地线距离,这可以量化相似性,但由于需要穷举参数化搜索,计算量很大。最近的进展提出了启发式方法来简化这些计算,例如基于形状的主轴固定参数化,在保持高精度的同时显着降低计算成本(例如,红细胞分类的96.03%)。本文介绍了一个软件工具,它利用这种启发式来有效地计算形状空间距离,根据形状的长轴对齐形状,并使用圆形和椭圆等模板。该工具加速形态分析,使其成为生物学和医学等领域高性能应用的理想选择。通过简化形状之间测地线距离的计算和实现信息的快速检索,该软件改善了研究工作流程,并支持从细胞形态学到血液学诊断等不同领域的形状相关特征的研究。

Conventional vocabulary assessments emphasize precision rather than hesitation and rapidity. A machine learning system was developed utilizing behavioral analysis and linguistic insights to identify vocabulary gaps in Turkish language learners. This system integrates hesitation counts, reaction times, and answer attempts with word difficulty and thematic elements. Vocabulary strength was computed using a rule-based equation derived from behavioral indications. With 89% accuracy, 86% precision, 91% recall, and an 88% F1 score, the model showed better performance than the linear and Poisson kernel alternatives. By effectively separating complex interactions, the RBF kernel minimizes unnecessary actions and ensures accurate identification of real shortages.

smFISH_batchRun: A smFISH image processing tool for single-molecule RNA Detection and 3D reconstruction smFISH_batchRun:用于单分子RNA检测和3D重建的smFISH图像处理工具

Single-molecule RNA imaging has been made possible with the recent advances in microscopy methods. However, systematic analysis of these images has been challenging due to the highly variable background noise, even after applying sophisticated computational clearing methods. Here, we describe our custom MATLAB scripts that allow us to detect both nuclear nascent transcripts at the active transcription sites (ATS) and mature cytoplasmic mRNAs with single-molecule precision and reconstruct the tissue in 3D for further analysis. Our codes were initially optimized for the C. elegans germline but were designed to be broadly applicable to other species and tissue types.
单分子RNA成像已成为可能,随着显微镜方法的最新进展。然而,即使在应用复杂的计算清除方法之后,由于高度可变的背景噪声,对这些图像的系统分析一直具有挑战性。在这里,我们描述了我们自定义的MATLAB脚本,使我们能够以单分子精度检测活性转录位点(ATS)和成熟细胞质mrna的核新生转录本,并在3D中重建组织以进行进一步分析。我们的代码最初是针对秀丽隐杆线虫种系进行优化的,但后来被设计成广泛适用于其他物种和组织类型。

RadEx: An open source python package for nonlinear radon transformation 一个用于非线性氡变换的开源python包
IF 1.3 Q3 COMPUTER SCIENCE, SOFTWARE ENGINEERING Pub Date : 2025-07-01 Epub Date: 2025-07-21 DOI: 10.1016/j.simpa.2025.100779

Effective feature extraction from medical images is important for improving disease detection and assessment. Conventional linear transforms, such as the Radon transform, may not fully capture subtle and complex nonlinear features present in medical imaging data. To address these limitations, we present RadEx, a nonlinear extension of the Radon transform. RadEx employs parameterized nonlinear projections to facilitate the extraction of additional nonlinear feature representations from imaging modalities such as chest X-rays and retinal fundus images. Initial evaluations indicate that RadEx can offer improvements over traditional Radon transforms and raw image-based approaches in disease classification tasks, including COVID-19 detection from chest X-rays and diabetic retinopathy grading from retinal images. By capturing more complex structural and nonlinear patterns, RadEx may support enhanced diagnostic performance and illustrates the potential benefit of integrating adaptive mathematical transformations into medical imaging workflows.
有效的医学图像特征提取对于提高疾病的检测和评估具有重要意义。传统的线性变换,如Radon变换,可能不能完全捕获医学成像数据中存在的微妙和复杂的非线性特征。为了解决这些限制,我们提出radx, Radon变换的非线性扩展。RadEx采用参数化非线性投影,方便从胸部x光片和视网膜眼底图像等成像模式中提取额外的非线性特征表示。初步评估表明,在疾病分类任务中,RadEx可以比传统的氡变换和基于原始图像的方法提供改进,包括从胸部x射线检测COVID-19和从视网膜图像分级糖尿病视网膜病变。通过捕获更复杂的结构和非线性模式,radx可以支持增强的诊断性能,并说明将自适应数学转换集成到医学成像工作流程中的潜在好处。

Distributing medical supplies involves complex logistical challenges, including the need for optimized delivery routes and efficient packing. Medicines, whether ordered in small quantities or in bulk, are packed into cardboard boxes, which affect cargo dimensions, loading plans, and available delivery routes. Additionally, some medicines require refrigeration, making it necessary to coordinate both reefer and standard trucks. This study introduces MedRoPax, a comprehensive software solution designed to address these challenges. MedRoPax solves the 3D Loading Heterogeneous Vehicle Routing Problem (3LHVRP) and provides user-friendly tools for packing, loading visualization, and route planning. While tailored for medical supply distribution, MedRoPax is also well-suited for other logistics operations that demand both efficiency and safety.
分发医疗用品涉及复杂的后勤挑战,包括需要优化配送路线和高效包装。无论是小批量订购还是批量订购,药品都被包装在纸板箱中,这会影响货物尺寸、装载计划和可用的运输路线。此外,有些药品需要冷藏,因此必须协调冷藏箱和标准卡车。本研究介绍了MedRoPax,一个全面的软件解决方案,旨在解决这些挑战。MedRoPax解决了3D装载异构车辆路径问题(3LHVRP),并提供了用户友好的打包、装载可视化和路径规划工具。MedRoPax是为医疗用品配送量身定制的,同时也非常适合其他对效率和安全都有要求的物流业务。

FeVAcS is an open-source finite element software specializing in one dimensional periodic acoustic analyses with scattering obstacles. Leveraging FEniCS Project’s computational capabilities, it solves the Helmholtz equation variational form. This tool simplifies mesh generation, enhances acoustic visualization, and enables easy parameter manipulation for obstacle and domain geometries, along with wave property adjustments. Featuring a user-friendly browser interface, FeVAcS improves accessibility and result sharing. It serves as a vital tool for understanding complexities within exterior acoustic analyses.
FeVAcS是一个开源的有限元软件,专门用于一维周期性声学分析与散射障碍。利用FEniCS项目的计算能力,它解决了亥姆霍兹方程的变分形式。该工具简化了网格生成,增强了声学可视化,并且可以轻松地对障碍物和区域几何形状进行参数操作,以及波浪属性调整。具有用户友好的浏览器界面,FeVAcS提高了可访问性和结果共享。它是理解外部声学分析复杂性的重要工具。
