From graph Laplacian to ring polymer dynamics: part I

Abstract A graph-theoretic formulation of overdamped Langevin dynamics and constitutive equations for ring polymers is developed. The polymer molecule is represented as a bead–spring network whose connectivity is described by a graph Laplacian. Starting from overdamped stochastic...

Exponential convergence can happen in weighted Birkhoff averages via quasi‐periodicity with arbitrary nonresonance and low regularity

Abstract Since Krengel's work [Monatsh. Math. 86 (1978/79), 3–6] in 1978, it has been widely known that no effective rate of convergence exists in the ergodic theorem. For toral translations, however, by choosing appropriate weights one can accelerate the convergence of ergodic a...

Level of education is associated with risk of kidney diseases in middle-aged and elderly adults: evidence from the CHARLS

Although numerous studies have indicated that various socioeconomic factors influence the risk of developing kidney disease, clinical evidence regarding the relationship between level of education (LoE) and the risk of kidney disease remains insufficient. This study aims to evalu...

How university drive agribusiness entrepreneurial opportunity exploitation? A knowledge orchestration perspective

Purpose This study aims to explore how university knowledge embedding enables agribusinesses to exploit entrepreneurial opportunities in resource-constrained environments. Specifically, it examines the dynamic transition from passive adaptation to proactive creation in firm-unive...

Unlocking the Anticancer Potential of Patchouli Leaves: Molecular Mechanisms and Translational Perspectives

Cancer remains one of the leading causes of global mortality, with its incidence continuing to rise due to population growth, aging, lifestyle factors, and environmental exposures. Despite significant advances in early diagnosis and therapeutic strategies, the clinical management...

Continuous FMD-Net: A Physics-Driven Algorithm-Unrolling Network with Spatio-Temporal Dual Sparsity for Adaptive Fault Diagnosis

Extracting and demodulating weak fault signatures from rotating machinery under heavy background noise remains a significant challenge. Conventional methods such as Feature Mode Decomposition (FMD) rely on manual parameter tuning and are highly susceptible to mode mixing. To addr...

Nature contact and adolescent paper-reuse behavior: place attachment versus climate anxiety in a two-wave study of Chinese adolescents

Nature contact is often linked to pro-environmental behavior, but the psychological processes connecting these experiences to later behavior remain unclear. This study examined reusing paper and compared two theoretically distinct pathways: a positive-bonding pathway through plac...

The KAT8-CDK1 K33 acetylation axis drives doxorubicin resistance by suppressing ferroptosis and apoptosis in breast cancer

Abstract Doxorubicin (Dox) resistance severely limits therapeutic efficacy in breast cancer, yet the epigenetic mechanisms linking cell-cycle control to therapy-induced cell death remain unclear. Here, we identify the histone acetyltransferase KAT8 as a critical driver of Dox res...
