Drawing as an encoding strategy for memory: An fNIRS study

Drawing reliably improves memory relative to other encoding strategies (such as reading and writing), a phenomenon known as the drawing effect. Although behavioral studies have documented this advantage, the neural mechanisms supporting it remain unclear. The present study examin...

The Role of Photobiomodulation Therapy in Enhancing Neurogenesis: Mechanisms and Applications

BACKGROUND: Adult neurogenesis, critical for neural repair and functional plasticity, is impaired in neurological disorders including Alzheimer's disease (AD), Parkinson's disease (PD), and traumatic brain injury (TBI). OBJECTIVE: This review summarizes the physiological basis of...

Assessing coastal flooding risk in newly reclaimed areas under the influence of relative sea level rise and multiple drivers

Sea level rise, combined with extreme coastal flooding, poses a significant threat to the socio-economic development of coastal areas. Meanwhile, some coastal cities are increasingly reclaiming land seaward to address urban land pressure. However, existing studies have rarely ass...

Too little time, too much to do: how time poverty undermines employees’ proactive service behavior

Purpose This paper aims to examine the relationship between time poverty and hotel employees’ proactive service behavior by identifying future self-continuity as a mediator and competitive climate as a moderator. Design/methodology/approach This research uses a multimethod design...

Sustaining teachers’ epistemic agency in AI-supported instructional design: An exploratory design-based study of a conversational-function approach

The increasing use of generative AI in instructional design raises concerns about cognitive outsourcing, as lesson planning may become overly shaped by algorithmic outputs. Because learning is situated and personalized, sustaining teachers' epistemic agency—responsibility for ins...

Dual-Factor Mental Health Profiles Among Rural School Teachers in China: Associations With Sociodemographic, Occupational, Health Behaviors, and Psychosocial Factors

This study aimed to identify heterogeneous profiles of school teachers in rural China and to examine whether these profiles differed across sociodemographic, work-related, health behavior, and psychosocial factors. Participants were 513 teachers from rural schools in Hunan Provin...

Head Group-Induced Interfacial Water Rearrangement during Demulsification: A Study at the Molecular Level

Abstract Tight oil emulsions produced in tertiary oil recovery display ultrahigh stability, whereas conventional block polyether demulsifiers show inadequate demulsification performance under harsh high-temperature and high-salinity conditions. However, the relationship between t...

Melanomacrophages exhibit FDC-like features: aquatic reovirus induces melanomacrophage death to suppress antibody responses

Genotype II grass carp reovirus (GCRV-II)-caused grass carp hemorrhagic disease severely restricts aquaculture, yet its adaptive immune evasion mechanism remains unclear. In mammals, follicular dendritic cells (FDCs) act as the core antigen-presenting cells that drive germinal ce...

Construction of topological insulator Bi2Te3 bridged Zn3In2S6/C3N5 ternary heterojunction with step-scheme/type-I synergistic charge transfer for boosted visible-light photocatalytic hydrogen evolution

Addressing the core electrochemical bottlenecks of sluggish interfacial charge transfer and the charge separation-redox capability trade-off in photoelectrochemical water splitting, this work introduces 3D topological insulator Bi 2 Te 3 as a backscattering-free electrochemical c...

Psychological distance and negative emotion: the moderating role of social distance

Psychological distance has been extensively explored in social cognition and has recently been advanced in affective science. However, existing studies have primarily examined the effect of a single psychological distance on emotion, with less attention paid to the interaction ef...

Visualizing Heteroepitaxy of Angle-Oriented GeSe/WSe2 Heterostructures for Near-Infrared Ultrasensitive Photodetectors

Abstract Precise heteroepitaxial control in van der Waals (vdW) heterostructures remains a challenge. Here, we demonstrate a visualized and directed heteroepitaxy strategy for GeSe on WSe2 by integrating in situ imaging with symmetry-guided physical vapor deposition. Real-time ob...

Compact Two‐Dimensional Focal‐Plane‐Array Beam Steering on Thin‐Film Lithium Tantalate Enabled by Binary Electrode Coding

ABSTRACT Two‐dimensional (2D) solid‐state optical beam‐steering systems are highly desirable for next‐generation light sensing and free‐space optical communication applications. Yet, the scaling of the on‐chip optical emitters to a large number is still challenging, concerning di...

Controllable multiple optical bottles of the circular Airy Swallowtail beam

Although optical bottles have received considerable attention, research on the precise manipulation of multiple-optical-bottle structures has remained relatively limited. In this paper, we innovatively propose a composite circular Airy Swallowtail beam (CASB). Compared with other...

Pseudoscalar Yukawa coupling induced helical asymmetry in fermionic preheating

Abstract In this study, we investigate the fermionic helical asymmetry during preheating by introducing a model in which the Dirac field $$\psi $$ ψ couples to the scalar inflaton $$\phi $$ ϕ directly through the pseudoscalar Yukawa mechanism described by the term $$- g\frac{\phi...

Inheritance of the epigenetic signature and reduced intermuscular bone phenotype acquired via DNA methylation editing of the runx2 b promoter in zebrafish.

promoter methylation levels may synergistically induce additional epigenetic modifications, potentially affecting the PPAR signaling pathway and FoxO transcription factor regulation, which appears to inhibit osteoblast proliferation and differentiation. Overall, this study demons...

Extremal Q-index problem in outerplanar graphs

For connected outerplanar graphs on n vertices, we identify the unique graph that attains the maximum Q -index when cycles of a given length are forbidden for n ≥ 5 , and similarly when vertex-disjoint paths of a given length are forbidden for sufficiently large n .

Giant Ferroelectric Domain Wall Conductance in MoS2/PbTiO3 Heterostructure for High-Density Memory

Abstract Domain wall (DW) electronics hold promise for high-density computing, but their implementation is limited by low read currents and high operating voltages in bulk ferroelectric oxides. Here, we present a monolayer molybdenum disulfide (MoS2)/PbTiO3 (PTO) van der Waals (v...

Maternal childhood maltreatment and adolescent internalizing problems: Intergenerational pathways via emotion regulation difficulties and offspring maltreatment

Background Research has established the intergenerational transmission of maternal childhood maltreatment to offspring internalizing problems. However, the potential indirect pathways underlying this intergenerational association remain under-explored, particularly regarding how...

An automated analytical framework for identifying reaction channels and structural evolution in multi-channel nonadiabatic dynamics: Combining dimensionality reduction, clustering, and information entropy

The automatic identification of reaction channels and key nuclear motions from nonadiabatic dynamics simulations remains a major challenge. Traditional manual analysis is inefficient and relies heavily on expert intuition, creating a bottleneck for interpreting complex photochemi...

Covalent‐Organic Framework‐Manipulated Multi‐Reactant Activation Enables Polystyrene Electrodegradation in Tandem With Over‐Oxidation Product Upgrading

ABSTRACT Polystyrene (PS) waste is exceptionally difficult to chemically degrade under environmental conditions, and the high‐value utilization of low‐value C 1 products generated during the process has never been achieved. Herein, we constructed a metalloporphyrin–anthracene sp...
