Nonconstant Positive Steady States for a Predator–Prey System With Signal‐Dependent Diffusion

open access: yesMathematische Nachrichten, EarlyView.
ABSTRACT This paper investigates a highly nonlinear predator–prey reaction–diffusion system featuring signal‐dependent prey diffusion, where the motility of the prey is modulated by a chemical signal released by predators. For unbounded functional responses, we establish the global‐in‐time existence and uniform‐in‐time boundedness of classical ...

The Combined Effects of Variable Viscosity and Thermal Conductivity of An Unsteady Casson Fluid Flow Along a Vertical Porous Channel With Convective Cooling Walls, Using the Bivariate Spectral Local Linearization Method

open access: yesMathematical Methods in the Applied Sciences, EarlyView.
ABSTRACT This study examines the combined impact of different thermal conductivity and viscosity on unsteady non‐Newtonian Casson fluid flow of incompressible, electrical conductivity in a porous vertical channel with convective cooling walls, uniform magnetic field, and constant pressure gradient.

Wind-Radiation Data-Driven Modelling Using Derivative Transform, Deep-LSTM, and Stochastic Tree AI Learning in 2-Layer Meteo-Patterns

open access: yesModelling
Self-contained local forecasting of wind and solar series can improve operational planning of wind farms and photovoltaic (PV) plant day-cycles in addition to numerical models, which are mostly behind time due to high simulation costs.

Existence and Stability Analysis of Classical and Fractional‐Order Generalized Brusselator Reaction‐Diffusion System

open access: yesMathematical Methods in the Applied Sciences, EarlyView.
ABSTRACT The present work is devoted to establishing existence results and examining the stability properties of solutions associated with a generalized Brusselator reaction–diffusion system in both the classical and fractional‐order settings. The corresponding ODE and PDE formulations are considered to establish the global existence of solutions in ...

Finite‐Difference Reduced Transfer Matrix Method for Multibody Systems With Rotating Beams

open access: yesInternational Journal of Mechanical System Dynamics, EarlyView.
ABSTRACT Multibody systems with rotating beams serve as critical simplified models of core components in engineering systems; however, existing analytical and numerical methods have limitations in analyzing their complex dynamic behavior. This paper proposes the Finite‐Difference Reduced Multibody System Transfer Matrix Method (FD‐RMSTMM), which ...

Polyphyllin I Alleviates Alcoholic Liver Disease via Modulation of the Phosphodiesterase 6D–Cyclic Guanosine Monophosphate–Protein Kinase G Axis

open access: yesPhytotherapy Research, EarlyView.
ABSTRACT Alcoholic liver disease (ALD) is a multifaceted disorder in which oxidative injury, iron‐dependent ferroptosis, steatosis, and inflammation are closely intertwined. Consequently, therapeutic strategies targeting a single pathway often produce limited clinical benefits.

Single‐Vesicle Functional Nanophenotyping Reveals Heterogeneous PD‐L1 Accessibility in Triple‐Negative Breast Cancer

open access: yesSmall Methods, EarlyView.
Graphical Abstract. High‐speed atomic force microscopy enables real‐time, label‐free visualization of antibody interactions with individual extracellular vesicles. By quantifying binding frequency and dwell time, this approach reveals functional PD‐L1 accessibility that cannot be inferred from protein abundance alone, uncovering nanoscale heterogeneity
