Dynamic Behavior of Pressure‐Responsive Microphase‐Separated Diblock Copolymers

open access: yesJournal of Polymer Science, EarlyView.
A dynamic theory based on a lattice vacancy model provides quantitative physical insights into nonequilibrium behavior and flow properties of pressure‐responsive block copolymers. ABSTRACT The dynamics of pressure‐induced order–disorder transitions in diblock copolymer systems and their effect on the flow properties are investigated.

2‐Adic Quantum Mechanics, Continuous‐Time Quantum Walks, and the Space Discreteness

open access: yesFortschritte der Physik, EarlyView.
Abstract The authors show that a large class of 2‐adic Schrödinger equations is the scaling limit of certain continuous‐time quantum Markov chains (CTQMCs). Practically, a discretization of such an equation gives a CTQMC. As a practical result, new types of continuous‐time quantum walks (CTQWs) on graphs using two symmetric matrices are constructed ...

Role of the DPP4 Receptor in SARS‐CoV Entry: Insights From Docking and Molecular Dynamics Simulations

open access: yesProteins: Structure, Function, and Bioinformatics, EarlyView.
ABSTRACT Protein–receptor interactions play a critical role in viral entry and pathogenesis. While ACE2 is the primary receptor for SARS‐CoV, the role of DPP4 as potential coreceptor remains underexplored. This study investigates the binding mechanisms and dissociation dynamics of the SARS‐CoV/DPP4, SARS‐CoV/ACE2 and MERS‐CoV/DPP4 complexes using ...

Nucleation and Propagation of Traveling Charge Domains in a Planar AlGaN/GaN Triode Structure

open access: yesphysica status solidi (a), EarlyView.
This work presents a novel model for the nucleation of charge domain instabilities in semiconductors exhibiting negative differential drift velocity, identifying diffusion as the key factor inhibiting domain formation. A planar Gunn triode structure is proposed which overcomes obstacles to the realization of GaN‐based Gunn effect devices with ...

Structure and Migration Mechanisms of Oxygen Interstitial Defects in β‐Ga2O3

open access: yesphysica status solidi (b), EarlyView.
The structures and diffusion mechanisms of interstitial oxygen in different charge states in β‐Ga2O3 are extensively studied using density functional theory. The results provide a detailed map of the potential energy surface for oxygen interstitials in β‐Ga2O3 and demonstrate how these ions migrate between different rings in the structure.
