Rare‐Earth–Functionalized Carbon Dot Hydrogels as Mechanically Robust Antibacterial Wound Dressings

Advanced Healthcare Materials, EarlyView.
The schematic depicts a dynamically cross‐linked PVA hydrogel network in which reversible borate ester bonds and hydrogen‐bonding interactions integrate lanthanum‐doped carbon dots (La‐CDs) and dipotassium glycyrrhizinate (DPG) to form a mechanically robust, multifunctional matrix.

It's not how you play the game, it's winning that matters: an experimental investigation of asymmetric contests [PDF]

This paper reports an experimental test of asymmetric Tullock contests. Both the simultaneous-move and sequential-move frameworks are considered. The introduction of asymmetries in the contest function generates experimental behavior qualitatively ...

Self‐Healing Hydrogel‐Enabled Modular Assembly of Bilayered Skin Construct for Hair Follicle Regeneration

Advanced Healthcare Materials, EarlyView.
Self‐healing assembly of two cell‐laden hydrogel layers creates a biomimetic skin construct that restores both dermal and epidermal functions, resulting in accelerated wound healing and enhanced hair follicle regeneration in a full‐thickness skin wound model. ABSTRACT Alopecia remains a pervasive clinical challenge, largely owing to the limited ability

Randomized Linear Search for a Drifted Brownian Target with Direction-Reversal Costs

Mathematics
This paper introduces a randomized linear-search model for a target moving on the real line according to Brownian motion with drift. The searcher alternates between the two directions through expanding random excursions, with a fixed cost incurred at ...

LEAD: Literature Enhanced Ab Initio Discovery of Nitride Dusting Layers for Enhanced Tunnel Magnetoresistance and Lower Resistance Magnetic Tunnel Junctions

Advanced Materials, EarlyView.
Magnetic tunnel junctions (MTJs) using MgO tunnel barriers face challenges of high resistance‐area product and low tunnel magnetoresistance (TMR). To discover alternative materials, Literature Enhanced Ab initio Discovery (LEAD) is developed. The LEAD‐predicted materials are theoretically evaluated, showing that MTJs with dusting of ScN or TiN on ...

A Geometry-Driven Aerodynamic Torque Model Based on Air-Mesh Area Variation With Solver Extension for GPU Acceleration

IEEE Access
Real-time rigid-body simulation commonly employs simplified aerodynamic models, where drag forces are applied only to translational motion. Although such models efficiently reduce velocity, they fail to generate stable and physically plausible rotational

Asymmetric Price Adjustment: Micro-foundations and Macroeconomic Implications [PDF]

We present a simple menu cost model which explains the finding that firms are more likely to adjust prices upward than downward. Asymmetric adjustment to shocks arises naturally, even without trend inflation, from the desire of firms to keep industry ...

Development of New Catalytic Asymmetric Routes towards a Cost-Driving Building Block of Nirmatrelvir [PDF]

Nirmatrelvir is an inhibitor of SARS-CoV-2 main protease and is the active ingredient in PaxlovidTM. Nirmatrelvir presents a significant synthetic challenge, in no small part due to a cost-driving lactam containing fragment with two stereogenic centers ...
