Thermosolutal and binary fluid convection as a 2 x 2 matrix problem

, 2001
We describe an interpretation of convection in binary fluid mixtures as a superposition of thermal and solutal problems, with coupling due to advection and proportional to the separation parameter S.

A Superlubricated Magnetically Steerable Microcatheter with Integrated Optical and Fluidic Channels

Advanced Robotics Research, EarlyView.
A magnetically steerable microcatheter with integrated optical and fluidic channels is developed for multifunctional navigation in tortuous anatomical environments. A surface‐grafted hydrogel coating enables low‐friction actuation. The device demonstrates stable light and fluid delivery during magnetic manipulation, offering a compact platform for ...

NLS Bifurcations on the bowtie combinatorial graph and the dumbbell metric graph

, 2018
We consider the bifurcations of standing wave solutions to the nonlinear Schr\"odinger equation (NLS) posed on a quantum graph consisting of two loops connected by a single edge, the so-called dumbbell, recently studied by Marzuola and Pelinovsky.

Tie2‐Dependent Mechanisms Influence Leptomeningeal Collateral Dynamics and Reperfusion Following Stroke

Advanced Science, EarlyView.
This work demonstrates that endothelial EphA4 limits Tie2 activation and curbs leptomeningeal collateral expansion after ischemic stroke. Pharmacological activation of Tie2 by an Ang‐1 mimetic or genetic loss of EphA4 stimulates collateral vessel growth, improves cerebral perfusion, and enhances neurological recovery.

Multistable Solitons in the Cubic-Quintic Discrete Nonlinear Schr\"odinger Equation

, 2005
We analyze the existence and stability of localized solutions in the one-dimensional discrete nonlinear Schr\"{o}dinger (DNLS) equation with a combination of competing self-focusing cubic and defocusing quintic onsite nonlinearities.

Catalytic Electron‐Driven Non‐Equilibrium Phase Transition in Quantum Electronic Heterostructures

Advanced Science, EarlyView.
This study proposes an innovative method to control the phase of heterostructured materials via electron flow manipulation. Leveraging this technique, a new topological phase is achieved that hosts excitons at the interface of a topological insulator.

Single‐Cell RNA Sequencing of Thyroid Tissues Reveals Pathogenesis of Graves' Disease

Advanced Science, EarlyView.
Using single‐cell RNA sequencing and TCR profiling, this study constructed an immune cell atlas in thyroid tissue of Graves’ disease (GD), revealing dominant IFN‐γ‐secreting CD4+ T cells, expanded Tph and CD11c+ B cells, and enriched T/NK cells. Notably, GD thyroid follicular cells (TFCs) activated γδ T cells, which recruited cDC1 cells, suggesting a ...

Three‐Channel Electron Engineered Fe‐88A@CeO2/CDs Nanozyme with Enhanced Oxidase‐Like Activity for Efficient Biomimetic Catalysis

Advanced Science, EarlyView.
xx xx. Abstract Iron‐based metal‐organic framework (MOF) nanozymes have garnered considerable attention owing to a large specific surface area, adjustable porosity, large Fe‐O clusters, and unsaturated Fe sites. However, the sluggish charge‐transfer rate and restricted active sites of the nanozymes lead to poor enzyme‐like activity and further impede ...

Synthesis, Biological Activity, and Molecular Dynamics Simulations of LNA‐Charge Neutral Linkages for Enhanced Splice‐Switching Antisense Oligonucleotides

Angewandte Chemie, EarlyView.
Splice‐switching oligonucleotides are used to treat severe genetic conditions including Duchenne Muscular Dystrophy, but new chemistries are urgently required to improve their efficacy. In this work locked nucleic acid (LNA) is coupled to different charge neutral DNA backbones which are studied by structural, thermodynamic, and biological methods.
