Investigating the Impact of Sportswear Design on the Psychological States of University Students in Physical Education Courses This study examines the dual role of sportswear as both a functional textile product and a psychological influencer within the context of university physical education (PE). While textile engineering research has extensively opti-mized the ergonomic and physicochemical properties of athletic apparel for elite performance, the psychological implications of fundamental garment design parameters among non-athlete wearers remain insufficiently ex-plored. This research systematically investigates the psychological effects of two core apparel design variables: fabric color (an aesthetic attribute) and garment fit (a structural, ergonomic attribute). Utilizing a 2 �� 2 be-tween-subjects experimental design (N = 256), the study evaluated custom-manufactured sportswear in which all textile properties (100% polyester interlock, 150 g/m2) were held constant except for the manipulated variables: color (red vs. gray) and fit. The ergonomic fit was developed using anthropometric data, contrasted with a stand-ard loose-fit pattern. Psychological wear comfort was assessed using validated instruments measuring intrinsic motivation (IMI), self-confidence (SSES), and mood (PANAS), administered pre- and post-activity. A two-way ANO-VA of change scores revealed that fabric color exerted a significant main effect on motivation (F (1, 252) = 18.31, p &lt; 0.001, ��p2 = 0.067), whereas garment fit significantly influenced self-confidence (F(1, 252) = 21.58, p &lt; 0.001). These findings provide empirical evidence that strategic manipulation of basic textile and apparel design parame-ters��specifically color selection and garment construction for fit��can directly enhance the psychological comfort and engagement of wearers. The research contributes to the field of functional textiles by quantifying the psycho-logical dimension of wear comfort and offers actionable insights for textile manufacturers and apparel designers.

An Experiment and Simulation Study on the Tensile Behavior of Cotton Ring-Spun Yarn with Twisted Staple Fibers This paper investigates the tensile behavior of cotton ring-spun yarn through experimental testing, numerical simulation, and theoretical calculation. Firstly, scanning electron microscope testing of the microscopic geometric morphologies of yarns was performed for the development of basic finite element (FE) models. Then, the influences of tensile speed and yarn length on the tensile properties of yarn were studied using tensile experiments. Numerical simulations were further performed to investigate the effects of yarn diameter, twist angle, and friction between fibers on the tensile modulus of yarn. Finally, a modified 'rule-of-mixtures' equation was proposed to effectively calculate the tensile modulus of yarn through incorporating the friction correction factor. The experimental results show that the tensile modulus and strength of tested yarn are significantly affected by the yarn structure and are not sensitive to the yarn length and tensile speed. Furthermore, the tensile moduli of yarns obtained from the numerical simulations show a good fitting accuracy with those obtained from experimental tests when the friction coefficient is set to 0.5 in the FE models. The simulation results show that the twist angle and friction coefficient are two key factors affecting the tensile modulus of yarn. The modified 'rule-of-mixtures' equation presents better accuracy for the calculation of the tensile modulus of yarn compared with the traditional 'rule-of-mixtures' equation, which can be used to replace the FE modeling and simulation and reduce the computational cost. This work will provide a deeper understanding of the mechanical properties of cotton ring-spun yarns and enhance their application in the textile industry.

The viscoelastic rheology of transient diffusion creep Abstract Polycrystalline materials have a viscoelastic rheology where the strains produced by stresses depend on the timescale of deformation. Energy can be stored elastically within grain interiors and dissipated by a variety of different mechanisms. One such dissipation mechanism is diffusionally accommodated/assisted grain boundary sliding, also known as transient diffusion creep. Here we detail a simple reference model of transient diffusion creep, based on finite element calculations with simple grain shapes: a regular hexagon in two dimensions and a tetrakaidecadedron in three dimensions. The linear viscoelastic behaviour of the finite element models can be well-described by a parameterized extended Burgers model, which behaves as a Maxwell model at low frequencies and as an Andrade model at high frequencies. The parametrization has a specific relaxation strength, Andrade exponent and Andrade time. The Andrade exponent depends only on the angles at which grains meet at triple junctions, and can be related to the exponents of stress singularities that occur at triple junctions in purely elastic models without diffusion. A comparison with laboratory experiments shows that the simple models here provide a lower bound on the observed attenuation. However, there are also clearly additional dissipative processes occurring in laboratory experiments that are not described by these simple models.

Stigmasterol upregulates PDGFRα, contributing to white matter protection and anxiolytic-like behavior in a mouse model of vanadium-induced demyelination These findings suggest that stigmasterol confers neuroprotection by preserving oligodendrocyte lineage cells, enhancing PDGFRα-mediated precursor recruitment, and maintaining myelin integrity. By mitigating neuroinflammation and promoting remyelination, stigmasterol is a promising therapeutic candidate for metal-induced demyelinating disorders.

A Study on the Visual Expression and Graphic Design of Functional Textile Performance Data The modern textile industry relies on engineering materials, from natural fibers like cotton and wool to advanced synthetics, to deliver specific functionalities. The performance characteristics of these materials, determined by factors including yarn properties, weaving or knitting structures, and finishing chemical operations, are critical to their value. However, the complex physicochemical data from laboratory tests is often poorly communicated, creating a barrier to transparency for consumers and designers. This communication gap is also prevalent for high-performance materials such as technical leather, where performance metrics are key. This research addresses this challenge by studying the visual expression and graphic design of performance data for textiles. It establishes a design methodology rooted in materials science principles and textile technology standards (ISO, AATCC), analyzing how data from textile testing machinery can be transformed into intuitive graphics. Through case studies on visualizing properties relevant to both synthetic and natural fibers, the paper develops and evaluates visual systems, including a novel ��functional textile performance quad�� (FTPQ) framework. The study argues that adopting a standardized, clear visual language would be a crucial step towards sustainable development in the textile industry. It enhances transparency, empowers informed product selection, and allows for the effective validation of high-performance, durable fiber products, providing actionable guidelines for the textile products and processing sector.

Unlocking Sinan’s Architectural Language: Modular Design Through Geometric Recursion Abstract This study investigates the possibility that Architect Sinan employed a recursive geometric modulation system—rooted in the use of the circle and the square—in the design of his architectural masterpieces. Through detailed proportional analyses of the Privy Chamber of Sultan Murad III and the Selimiye Mosque, the research explores how a series of circles correspond precisely to critical structural and spatial elements of the buildings. Following these two examples, the Haseki Hürrem Bath—one of Sinan’s early works—was examined within the context of ad quadratum to further test the study’s approach. The results reveal a design methodology so deliberate and consistent that it cannot be attributed to coincidence. These findings suggest that the recursive application of modular circles and squares may have served as a foundational design tool, guiding both the aesthetic and structural logic of Sinan’s architecture. This research emphasizes geometric discipline over speculative symbolism, proposing that Sinan’s mastery lay in a refined system of modulation.

Inverse Stereographic Projection of Fibonacci Points onto the Quadric Surfaces In the present work, the inverse stereographic projection of Fibonacci points onto quadric surfaces of revolution is investigated. The construction of Fibonacci points from Fibonacci numbers, together with the one-to-one and invertible nature of stereographic projection, enables the establishment of new mathematical relations on quadric surfaces.} Cassini and Catalan identities are analyzed and mapped onto quadric surfaces to demonstrate how classical identities transform under this mapping, thereby opening new application areas for Fibonacci numbers on the surface of quadrics. In two dimensional plane, in addition to points, special Fibonacci related grids, circles, and spirals are considered. Their inverse stereographic projections are obtained. It is shown that the surfaces of quadrics can be partitioned into special domains whose boundaries can be fully expressed in terms of Fibonacci related curves. Because quadric surfaces frequently appear in botanical structures, these new relations may provide new insights into the biological applications of Fibonacci numbers in developmental biology.

Asymptotic analysis of the total quasi-steady state approximation for the Michaelis–Menten enzyme kinetic reactions We consider a stochastic model of the Michaelis–Menten (MM) enzyme kinetic reactions in terms of Stochastic Differential Equations (SDEs) driven by Poisson Random Measures (PRMs). It has been argued that among various Quasi-Steady State Approximations (QSSAs) for the deterministic model of such chemical reactions, the total QSSA (tQSSA) is the most accurate approximation, and it is valid for a wider range of parameter values than the standard QSSA (sQSSA). While the sQSSA for this model has been rigorously derived from a probabilistic perspective at least as early as 2006 in [4] , a rigorous study of the tQSSA for the stochastic model appears missing. We fill in this gap by deriving it as a Functional Law of Large Numbers (FLLN), and also studying the fluctuations around this approximation as a Functional Central Limit Theorem (FCLT).

Unravelling the service lifespan of garments ― empirical insights on use time and use intensity In response to the global environmental crisis, reducing the impact of production and consumption is essential. Within the clothing system, research and policy have focused primarily on sustainable production and end-of-life management, neglecting the use phase. Yet, understanding how garments are used—and how this varies across products and users—is essential to accurately assess environmental impacts and design effective interventions. This study analyzes data from in-person visits with 160 adult participants in Flanders (Belgium) to provide a comprehensive overview of garment service lifespans across 12 garment categories and 6 wear occasions using three complementary metrics: use time in years, use intensity in wears, and use intensity in washing cycles. The results reveal substantial variation both within and across garment types. For example, a t-shirt for informal use is kept on average four years, worn 33 times, and washed 18 times, whereas a t-shirt for formal use is kept five years but is worn only nine times and washed six times, while a coat for informal use is kept for five years, worn 136 times, but hardly ever washed. Even within garment types, the large observed interquartile ranges indicate pronounced heterogeneity in service lifespan. These findings demonstrate the importance of context-specific data on garment use to understand the function garments fulfil, a prerequisite to assess their environmental impact. By providing empirical insights into garment use behavior, this study informs researchers and policymakers in developing targeted strategies to promote a more sustainable clothing system.

Fractal rep-tiles of the plane via reflections and integer matrices The fractal rep-tiles of the Euclidean plane considered in this article are examples of rep-tiles (tilings) with fractal boundaries. Several new examples of fractal rep-tiles are constructed using reflection transformations and integer matrices. A new class of foldable fractal rep-tiles based on general reflection mappings is introduced, and it is shown that these rep-tiles tile the plane using similitudes, including reflections, if the iterated function system (IFS) satisfies lattice tiling conditions. We prove the existence of foldable fractal 2-rep and 4-rep tiles that exhibit novel properties (chirality and aperiodicity) caused by reflection mappings. Fractal variations of foldable rep-tiles are also constructed. The fractal rep-tiles and the foldable rep-tiles presented here are in one-to-one correspondence with finite reflection groups, and this novel class of foldable rep-tiles can be lifted to construct new classes of fractal rep-tiles with roots in classical reflection groups. The images of rep-tiles are rendered using the random iteration algorithm, which is one of the popular iterative methods to generate self-similar fractals and tilings.

Comparison and excitation optimization of commercial quartz tuning forks for QEPAS Quartz-enhanced photoacoustic spectroscopy (QEPAS) is a powerful technique for trace gas sensing, in which the quartz tuning fork (QTF) plays a key role in determining detection performance. Although custom-designed QTFs have shown enhanced sensitivity, commercially available QTFs remain attractive for practical QEPAS sensors due to their low cost and high reproducibility. In this work, four commercial quartz tuning forks with different geometrical parameters and resonance frequencies are systematically investigated for water vapor detection. The resonance characteristics of each QTF are experimentally measured, and the laser excitation position is individually optimized according to the tuning fork geometry. Using a 1,392 nm distributed feedback laser and a 1.8% H 2 O sample, the QEPAS performance of the four QTFs is compared under optimized conditions. Significant differences are observed in optimal excitation position, signal amplitude, and signal-to-noise ratio, with the standard 32.7 kHz QTF achieving the highest SNR of 430.4. These results demonstrate that commercial QTFs cannot be treated as interchangeable components and provide practical guidance for their selection and optimization in cost-effective QEPAS sensors.
