Girth Characterization of (3,29)-Regular Bipartite Graphs and Their Associated LDPC Codes

This paper studies a family of (3,29)-regular bipartite graphs introduced by Tanner for low-density parity-check (LDPC) codes. For a prime p≡1(mod87), the graph has 3p left vertices and 29p right vertices. In the associated LDPC code, the right vertices (there are 29p of them, ea...

Peer to multi peer energy trading for renewable communities using blockchain smart contracts and social welfare allocation

H 2 refuelling corridors plus EV mobility services require joint handling of station scheduling, price-sensitive mobility response, multi-carrier dispatch, plus carbon-accounting rules. Prior studies have improved H 2 -station planning, carbon-aware scheduling, plus incentive pri...

Dynamic Diels–Alder-Crosslinked Zwitterionic Polyurethane Coatings with Self-Healing, Antibacterial, and Antifouling Properties

Coatings used in marine and humid environments are simultaneously exposed to biofouling and mechanical damage, which progressively compromise their interfacial functionality and service stability. In this study, polyurethane resins bearing terminal maleimide groups and sulfobetai...

Chitosan‐assisted dyeing of cotton with sodium copper chlorophyllin: Effects of process parameters on colour yield and fastness

Abstract Sodium copper chlorophyllin (SCC), a food‐grade green pigment, offers potential for sustainable textile coloration; however, its application to cotton is hindered by electrostatic repulsion with the negatively charged cellulose surface. In this study, chitosan was used t...

Development and performance evaluation of a novel borehole protection screen pipe for preventing borehole collapse in soft and fragmented rock strata

High-level roof borehole is one of the core technologies for gas control in high-gas mines in China. However, in soft and fragmented rock strata, the influence of mining-induced stress disturbance often causes compression-torsion deformation, borehole wall collapse, or dislocatio...

Bioinspired Surface Enabled by Anisotropic Pyramid Structure Arrays for Directional Liquid Self‐Transport

ABSTRACT Inspired by the phenomenon of directional liquid transport in natural organisms, various bionic surfaces with customized topological structures have been designed and fabricated, contributing to advances in such fields as microfluidics, microreactors, energy harvesting,...

Human metapneumovirus in central China, 2024–2025: epidemiology, co-infections, and temporal dynamics

Human metapneumovirus (HMPV) is a major cause of acute respiratory infections in children, but comprehensive data from sentinel surveillance in the post‑pandemic period remain limited. Understanding its epidemiology and co‑infection patterns is critical for surveillance and preve...

A landscape-aware multi-objective ant colony optimization framework for urban waste collection vehicle routing

Municipal solid waste collection routing has traditionally been optimized for transportation efficiency while neglecting the heterogeneous visual, acoustic, and ecological disturbances imposed on landscape sensitive urban regions. To address this limitation, a unified landscape-a...

RegPathTopic: deterministic regulatory-path topic modeling with traceable regulatory vocabularies for single-cell annotation

Single-cell RNA sequencing annotation can achieve high label accuracy when suitable references are available, but assigned labels do not necessarily expose the regulatory features associated with cell identity or state. Existing regulator-activity methods address related biologic...

Study on Preparation and Hydration Mechanism of Sand Washing Residue Mud-Based LC3 Cement by Mechanical–Thermal Activation

To enhance the application value of sand washing residue mud (SWRM) and mitigate its adverse environmental impacts, this study focuses on the resource utilization of SWRM. The research employed a combined mechanical–thermal activation method to enhance the activity of SWRM and ut...

Solvent-Free Ball Milling Combined with Hot Pressing for Fabrication of PLA@LM Functional Composites with Hydrolytic Degradability

Abstract The integration of liquid metals (LM) into biodegradable polymer matrices offers a promising route toward functional sustainable composites, while it is often hindered by solvent residues, poor dispersion, and compromised mechanical properties. Herein, we report a solven...

Theoretical Study on the Rheology-Driven Lubrication Synergy of Gel on Textured High-Entropy Alloy Coatings

This work is a theoretical study aimed to address the lubrication failure of Tom-Pac TP-2557 gel lubricant on the textured high-entropy alloy coatings (THEACs) under wide-temperature-range operating conditions; the rheological lubrication properties of the surface are investigate...

The SF3b complex in cancer: structural basis, molecular mechanisms, and therapeutic opportunities

Aberrant alternative splicing is increasingly recognized as a fundamental driver of cancer initiation and progression. The splicing factor 3b (SF3b) complex, an essential component of the U2 small nuclear ribonucleoprotein (snRNP), plays a pivotal role in branch point sequence (B...

Triptycene-Cored Double [5]Helicene: Chirality Transfervia the R / S Triptycene Core to P / M Helical Motifs

Abstract A series of double [5]helicenes with a triptycene core were synthesized via photocyclization. Single-crystal X-ray analysis unambiguously confirms these helicenes with an R/S triptycene core and two M/P [5]helicene subunits. Transfer of the central axially helical chiral...

Energy-Transfer-Driven[2 + 2] Cycloaddition: Synthesisof Cyclobutane-Fused Tetracycles from Indenes and Maleimides

Abstract Molecular skeletons containing fused cyclobutane rings are of significant value in drug discovery as they can increase the fraction of sp3 carbons (Fsp3) and impart conformational rigidity. Herein, we report a visible-light photocatalytic strategy for the intermolecular...

Study on mechanical properties and damage evolution of mortar reinforced by mixing basalt, carbon and polyester fibres in pairs

Fibre-reinforced mortar (FRM) has attracted much attention owing to its excellent mechanical properties. To further explore the influence of blended fibres on the mechanical properties and damage evolution of internal cracks in FRM, the effects of blended additions of basalt fibr...

Co–Cu Bimetallic ZIF-67@PDA-Based Fabrics: Trimodal Synergistic Antibacterial Performance for Reusable Protective Textiles

Abstract Protective textiles are essential for public health security, yet conventional textiles only physically filter microorganisms without rapid surface sterilization, easily becoming potential cross-infection sources. Commercial antibacterial variants also suffer from slow s...

Au Single‐Atom Interlayer Bridge Promotes Cross‐Layer Charge Transport and Intrinsic Catalytic Dual‐Sites Activation for Efficient CO 2 Photoreduction

ABSTRACT Layered photocatalysts are attractive for artificial photosynthesis, but their performance is often limited by inefficient charge transport across interlayer gaps and sluggish surface reaction kinetics. Herein, we propose a single‐atom interlayer bridge strategy by intro...

The influence of self-supporting personality on social anxiety in college students: the serial-mediating roles of attention bias and social problem-solving orientation

Social anxiety is highly prevalent among college students and is associated with impaired academic functioning and long-term social maladjustment. Although prior research has documented the adaptive value of self-supporting personality, the specific cognitive-behavioral mechanism...
