Summary: Solar interfacial evaporation is an effective method for obtaining freshwater using solar energy. By using zirconium carbide (ZrC) as a photothermal material, a ZrC decorated cotton yarn (ZrC@ cotton yarn) was designed and a Janus ZrC@fabric was created through traditional weaving craft, enabling stable solar desalination. This fabric-based evaporator demonstrated high evaporation rate (>95%) due to the strong sunlight absorption of the upper ZrC@ cotton yarn, while the lower hydrophilic cotton yarn facilitated efficient water transport for evaporation. It also exhibited anti-salt clogging during prolonged desalination.

Summary: The textile industry in China is still characterized by low efficiency, high resource consumption, and toxic emissions, particularly in the wet processing stage. It is crucial to recognize the environmental impact of wet processing to achieve sustainable development in the textile industry. This study used Life Cycle Assessment to evaluate the environmental impacts of wet processing in four textile enterprises in China, focusing on woven/knitted cotton and polyester fabrics. The results highlighted the dyeing unit as the major contributor to environmental impacts, driven by electricity consumption in cotton wet processing and detergent use in polyester wet processing. Recommendations for cleaner production in wet processing were proposed.

Summary: In this study, we investigate the programming of reactive systems that combine closed-loop control with performance-intensive components like Machine Learning (ML). By unifying concepts and algorithms from synchronous languages with commonly found abstractions in general-purpose and ML compilers, we are able to achieve a high degree of code reuse across embedded and high-performance computing. The generated code matches or outperforms state-of-the-art synchronous language compilers in computationally intensive ML applications.

Summary: PVC coated fabric, a lightweight and flexible structural material mainly used as a roof material, tends to suffer from mechanical failures such as tensile failure, peel, and tear under extreme conditions like heavy rain and wind. Despite several studies aiming to enhance its mechanical properties, there has been no significant improvement. In this study, the mechanical properties of PVC coated fabrics were improved by applying low viscosity PVC resin and using a 4 x 4 matt weave structure polyester fabric. The results showed that the tensile strength, tear load, and peel strength of the PVC coated fabric made with low viscosity PVC resin (D10) improved by approximately 3%, 11%, and 29% respectively compared to the one made with high viscosity PVC resin (D0). Additionally, the PVC coated fabric with a 4 x 4 matt weave structure demonstrated superior mechanical properties compared to those with a 1 x 1 plain weave structure or 2 x 2, 3 x 3 matt weave structure, attributable to its low crimp rate and low intersection point between the warp and weft yarns.

Summary: This study investigates the influence of weaving architectures and impact locations on the ballistic resistance of UHMWPE fabrics. The research establishes a mesoscopic model of UHMWPE fabric and verifies the accuracy of the numerical method. It further evaluates the impact resistance performances of different weaving architectures and explores the factors influencing fabric ballistic resistance. The findings demonstrate that the tensile strength of yarn plays a dominant role in the ballistic resistance of UHMWPE fabric, with plain fabric exhibiting the best anti-ballistic performance.

Summary: This study demonstrates the application of flock-reinforced shear thickening gel in protective equipment. Three-dimensional woven fabrics with folded structures were efficiently manufactured using a modified loom, and 3D FRSTG/woven fabric composites were produced through a simple inclusion procedure. These composites exhibit flexibility and breathability, and show responsive impact resistance. Wearable protective applications prove the integration of breathability and impact resistance in these composites.

Summary: Despite efforts to support learners from marginalized backgrounds in mathematics, achievement and participation disparities still exist, particularly for women and people of color. This paper explores the potential of a making-focused intervention that exposes youth to the mathematical practices inherent in weaving. The study showcases how student-created artifacts demonstrate learning and engagement with mathematics, similar to experienced weavers, and suggests that making mathematics visible through weaving could help address these disciplinary issues in the classroom.

Summary: The wellbeing of older adults can be improved by easier access to social networks and opportunities. However, in urban fringe communities, distance and health issues can limit their access to community life. Technology can facilitate socialization for older adults in geographically isolated areas, but it is important to understand how technology can fit into the existing social fabric and community infrastructure. This study explores the use of technology to support social connectivity in an urban fringe community through interviews and community mapping.

Summary: This paper proposes a sufficient condition to ensure that a Hermitian self-orthogonal GRS code is still a Hermitian self-orthogonal code. Based on this, a new general construction of infinitely families of quantum MDS codes is presented, and two new constructions of quantum MDS codes with flexible parameters are given using the trace function and norm function over finite fields. The constructed quantum MDS codes have different lengths from previous known results, and the minimum distances of all the q-ary quantum MDS codes are larger than q/2 + 1.

Summary: Two words p and q are avoided by the same number of length-n words, for all n, precisely when p and q have the same set of border lengths. Previous proofs of this theorem use generating functions but do not provide an explicit bijection. We give a bijective proof for all pairs p, q that have the same set of proper borders, establishing a natural bijection from the set of words avoiding p to the set of words avoiding q.

Summary: We define a poset called the Outer Tamari poset, which is shown to be isomorphic to a subposet of the Tamari lattice introduced by Pallo (1986) and further studied as the Comb poset by Csar, Sengupta, and Suksompong (2014). By using the Outer Tamari poset, we develop recursive formulas for the number of triangulations of the 3-dimensional cyclic polytopes. These triangulations can be considered as elements of both the higher Stasheff-Tamari orders in dimension three and the Tamari Block lattices defined in a previous article. Therefore, our work here can be seen as constructing recursive enumerations of these posets.

Summary: We improve upon Molloy's breakthrough result by adapting Bernshteyn's proof, achieving a stronger result that states triangle-free graphs can be colored from lists of size (1 +o(1))A/ log A, where vertices sharing a common color do not induce a triangle in G. We also extend this result to graphs of maximum degree A by proving the sufficiency of list sizes (1000 + o(1))A/ log A, as implied by a more general result due to Amini and Reed. Furthermore, we demonstrate that lists of length 2(r - 2)A log2 log2 A/ log2 A are sufficient if one replaces the triangle with any Kr with r >= 4. All of these bounds hold in the context of correspondence colorings.
