Navigating Gravity: Competing Effects Result in Opposing Taxis for Different Janus Swimmers

Small, EarlyView.
The combined effects of gravity and wall‐induced hydrodynamics on the motion of Janus colloids are investigated. Platinum‐ and copper‐coated silica microswimmers show distinct gravitactic alignment near surfaces due to different hydrodynamic couplings. This distinct gravitactic behavior enables separation of initially mixed active particles.

Design of Experiments (DoE)‐Optimized Polymeric Oxytocin Nanoparticles for Enhanced Nose‐to‐Brain Delivery

Small, EarlyView.
Intranasal (IN) delivery of PEGylated PLGA nanoparticles (NPs) loaded with oxytocin (OT) (OT‐NP‐PEG) is investigated as a strategy to enhance OT transport to the brain for treating autism and other neuropsychiatric disorders. The optimized NP formulation demonstrates appropriate physicochemical characteristics, improved stability, and enhanced mucosal ...

3D Customized Silica‐Based AFM Probes Fabricated by Selective Laser Etching

Small Methods, EarlyView.
Selective laser etching (SLE) enables the monolithic fabrication of customized, fully 3D silica AFM probes integrating both cantilever and tip with controlled 3D geometries. The process allows the production of either sharp or spherical tips with high design flexibility, reproducibility, and yield.

Cenozoic Tectonics Ignite Mitochondrial Codon Innovations Propelling Canid Body Size Evolution and Transcontinental Radiations

Integrative Zoology, EarlyView.
We decode mitochondrial genomes across all extant canids, revealing lineage‐specific codon optimization driven by altitude, predation, and body size. A tripartite framework integrates geological events, metabolic constraints, and adaptive radiation to explain carnivore evolution.

Closed‐Form Optimal Investment Under Generalized GARCH Models

European Financial Management, EarlyView.
ABSTRACT This paper introduces a new class of stochastic volatility models for asset prices, the generalized Heston Nandi GARCH (GHN‐GARCH), with the primary objective of optimal dynamic asset allocation under expected utility theory for constant relative risk aversion investors. We study some of its theoretical properties, and demonstrate that the GHN‐

The Role of Index Fund Ownership in the Era of Say‐on‐Pay

Financial Management, EarlyView.
ABSTRACT We examine whether and how index funds influence executive compensation in the post‐Say‐on‐Pay era. Using the annual reconstitution of the Russell indexes as a source of exogenous variation in index fund ownership, we document a causal effect of index ownership on CEO pay structure.

Skew Premiums Around Earnings Announcements

Financial Review, EarlyView.
ABSTRACT We examine skew premiums in equity options around earnings announcements. We use the realized returns to delta‐neutral risk reversal option spreads as a proxy for the skew premiums. We find skew premiums are economically significant around earnings announcements and are not explained by changes in variance risk premiums.
