Damping from the Escape Probability: A free calibration rule for diffusion-based reachability ranking in uncertain graphs

Future Work & Claimed Research Direction: Congestion-Aware Per-Node Damping While the global P̄_esc rule successfully calibrates the network-wide diffusion by setting the optimal baseline teleportation rate, our oracle ablations indicate an unexploited headroom (approx. +0.062 Spearman) available to a per-node damping...

Supercritical CO₂-assisted processing of PLA/PBAT blends with β-cyclodextrin/caffeic acid inclusion complexes: Mass transport modeling and disintegration

The engineering of polymeric composite foams with tailored cellular architecture remains a critical challenge for sustainable active packaging. In this study, PLA/PBAT composite foams were developed via a sequential supercritical CO₂ (scCO₂) impregnation and foaming. Caffeic acid (CA) was incorporated as the active ant...

Distribution of phytoplankton in the mixed layer: implication of krill abundance

The vertical trajectory of phytoplankton in the Antarctic ocean is modelled as a random walk with a diffusivity derived from a simple Ekman layer model and turbulence theory. The surface mixing layer is shallow, but diffusion is large enough to effect the vertical distribution of phytoplankton in the upper ocean.

Effects of Reaction Conditions on the Oxidation Behavior of Soot Particles: A Molecular Dynamics Study Based on Realistic Particle Structures

Abstract Soot is widely present in combustion systems, yet its oxidation mechanisms remain unclear due to complex internal structures. Core–shell soot models with different maturity levels are constructed using high-resolution transmission electron microscopy. Furthermore, the effects of reaction conditions on soot oxi...

Neuron–Astrocyte Coupling Regulates Ion Homeostasis and Neuronal Excitability in a Multi-Compartment Model

Introduction Neuronal excitability depends on transmembrane gradients of sodium (Na), potassium (K), and chloride (Cl). Astrocytes contribute to ionic homeostasis by regulating extracellular ion concentrations through membrane channels, transporters, and spatial buffering across their extended processes and syncytial n...

Digital Twins in stroke and spreading depression

Introduction Multiscale modeling (MSM) permits us to better understand how ischemia and spreading depolarization (SD) together damage neurons. However, it is a long step from there to producing clinical tools to counter or prevent stroke. Such tools must include clinical data from neurology and cardiology, endocrinolog...
