The priority state of items in visual working memory determines their influence on early visual processing.

Items held in visual working memory (VWM) influence early visual processing by enhancing memory-matching visual input. Depending on current task demands, memory items can have different priority states. Here, we investigated how the priority state of items in VWM affects two key aspects of early visual processing: access to visual awareness and attention allocation.

Research on the movement pattern and kinematic model of the hindlegs of the water boatman.

The special hindleg structure and swimming setae of a water boatman give it a high degree of maneuverability, which plays an important role in swimming. This paper used a high-speed photography platform to extract key points from videos, obtaining the forward and turning movement patterns of the water boatman's hindlegs, as well as the transformation patterns of the setae. A Fourier series was used to establish the movement models of each hindleg joint, and a kinematic model of the hindlegs was established to study the continuous movement characteristics of the hindlegs.

Impact of comb type on production performance, egg production quality, reproductive performance, and blood biochemical indexes in Tianfu chickens.

The comb, as a secondary sexual characteristic in chickens, serves as an important indicator of sexual maturity and potential reproductive. This study explored the relationship between comb types and production performance in Tianfu G01 chickens. Single-comb hens exhibited significantly lower laying rates compared to rose-comb hens during specific weeks (24-26, 27-28, 30, 32-34, and 38-43) but had higher average egg weights at 22, 23, 33, and 36-43 weeks.

Cobalt phosphide nanoarrays on a borate-modified nickel foam substrate as an efficient dual-electrocatalyst for overall water splitting.

Developing efficient non-noble metal dual-functional electrocatalysts for overall water splitting is essential for the production of green hydrogen. Given the significant advantages of self-supporting electrodes, regulating the growth of self-supporting nanoarrays on a conductive substrate is conducive to improving the electrocatalytic activity. In this work, aligned cobalt phosphide (CoP) nanowire arrays grown on borate-modified Ni foam substrate (CoP/R-NF) were utilized as a bifunctional electrocatalyst for both hydrogen evolution reactions (HER) and oxygen evolution reactions (OER) in alkaline solution.

Enhancing carbon enrichment by metal-organic cage to improve the electrocatalytic carbon dioxide reduction performance of silver-based catalyst.

Electrochemical reduction of carbon dioxide (CO) into value-added chemicals provide an alternative technology for achieving carbon neutrality. Limited mass transfer of CO in aqueous electrolyte and unsatisfied catalytic activity are the major determinants that inhibit the CO conversion at industrial current density level. Herein, an electroreduction-generated metallic Ag atomic clusters supported on metal organic cage (Ag AC/MOC) electrocatalyst is reported to improve the enrichment of inorganic carbon species over catalytic sites for efficient CO electroreduction.

Mechanically Resilient, Self-Healing, and Environmentally Adaptable Eutectogel-Based Triboelectric Nanogenerators for All-Weather Energy Harvesting and Human-Machine Interaction.

Triboelectric nanogenerators (TENGs) have garnered significant attention for mechanical energy harvesting, self-powered sensing, and human-machine interaction. However, their performance is often constrained by materials that lack sufficient mechanical robustness, self-healing capability, and adaptability to environmental extremes. Eutectogels, with their inherent ionic conductivity, thermal stability, and sustainability, offer an appealing alternative as flexible TENG electrodes, yet they typically suffer from weak damage endurance and insufficient self-healing capability.

Enhancing HBV-specific T cell responses through a combination of epigenetic modulation and immune checkpoint inhibition.

Objective: Chronic HBV infection (CHB) exhausts HBV-specific T cells, develops epigenetic imprints that impair immune responses, and limits the effectiveness of immune checkpoint inhibitor (ICI) monotherapy, such as αPD-L1. This study aimed to determine whether the DNA methyltransferase inhibitor decitabine (DAC) could reverse these epigenetic imprints and enhance ICI efficacy in restoring HBV-specific T cell responses.

Methods: We investigated HBV-specific T cell responses by 10-day in vitro stimulation of peripheral blood mononuclear cells (PBMCs) from patients with CHB.

A-D-A Molecular Design Strategy Enabling Ultrasensitive NIR Vapor Sensing.

Thin-film fluorescent chemosensors, characterized by their tunable design, high selectivity, and exceptional sensitivity, hold significant promise for gas detection applications. However, the simultaneous realization of the 3S attributes (sensitivity, selectivity, and stability) remains a formidable challenge, particularly in the underexplored field of near-infrared (NIR) gas detection. In this work, we employ an acceptor-donor-acceptor (A-D-A) molecular design strategy to drive the development of an organic semiconductor fluorescent material with a progressive red shift in the emission wavelength.

Hydrodynamic moiré superlattice.

The structural periodicity in photonic crystals guarantees the crystal's effective energy band structure, which is the fundamental cornerstone of topological and moiré physics. However, the shear modulus in most fluids is close to zero, which makes it challenging for fluids to maintain spatial periodicity akin to photonic crystals. We realized periodic vortices in hydrodynamic metamaterials and created a bilayer moiré superlattice by stacking and twisting two such vortex fluids.

NPR1 promotes blue light-induced plant photomorphogenesis by ubiquitinating and degrading PIF4.

Light is a major determinant of plant growth and survival. NONEXPRESSER OF PATHOGENESIS-RELATED GENES 1 (NPR1) acts as a receptor for salicylic acid (SA) and serves as the key regulator of SA-mediated immune responses. However, the mechanisms by which plants integrate light and SA signals in response to environmental changes, as well as the role of NPR1 in regulating plant photomorphogenesis, remain poorly understood.

Full Mouth Rehabilitation for a Patient with Angle's Class II Division 2 Associated Deep Overbite and Worn Dentition - Case Report With 2-Year Follow-Up and Literature Review.

Some of the critical clinical challenges encountered in the treatment of adult patients with deep overbite and worn dentition include correction of deep overbite, establishment of an appropriate occlusal vertical dimension (OVD), and maintenance of long-term occlusal stability. Although Angle's Class II division 2-associated deep anterior overbite is common in orthodontic treatment, simple prosthodontic treatment with great improvement of deep anterior overbite and worn dentition is infrequently reported. A 51-year-old man with Class II Division 2 malocclusion presented with hypo-divergent facial pattern, reduced lower facial height, and protuberant lips.

Regioselective Copolymerization of Glucose-Derived Allopyranoside Epoxide with Cyclic Anhydrides: Developing Precise Sugar-Functionalized Polyesters with Unique Altrose Linkages.

Uniform sugar-functionalized polyesters combine the benefits of sugar's structural diversity, biocompatibility, and biodegradability with precise postfunctionalization capabilities, making them a highly valuable class of materials with extensive application potential. However, the irregular placement of hydroxyl groups has limited the synthesis of these polyesters. Here, we present the first platform for uniform sugar-functionalized polyesters via regioselective ring-opening copolymerizations (ROCOPs) of allopyranoside anhydrosugar epoxide (, derived from d-glucose) with cyclic anhydrides, followed by complete selective deprotection.
