Repurposing Bird‐Based Acoustic Models for Amphibian Surveys: Strengths and Limitations in Real‐World Deployments

open access: yesRemote Sensing in Ecology and Conservation, EarlyView.
In this study, we developed AnuraSearch, an open‐source classifier for 11 Ukrainian amphibian species, by repurposing the avian BirdNET algorithm via transfer learning to process over 18,000 h of autonomous acoustic recordings. Although the model demonstrated high precision and successfully reconstructed detailed seasonal and diel vocal activity ...

Balancing coherence and resonance through linguistic framing: A longitudinal study of German biotechnology ventures' responses to the Covid‐19 pandemic

open access: yesStrategic Entrepreneurship Journal, EarlyView.
Abstract Research Summary Research suggests that ventures benefit from framing to gain audience support, yet how they utilize framing when exogenous shocks redirect attention remains unclear. Drawing on a longitudinal multiple‐case study of six biotechnology ventures following the COVID‐19 pandemic, we show how ventures balance coherence and resonance ...

A Compact Annular Electrostatic Clutch Joint: Dynamic Response Modeling and Time‐Sharing Control for Underactuated Robots

open access: yesSmartBot, EarlyView.
Electrostatic clutches offer programmable variable stiffness for multi‐DOF robots, but their continuous motion is usually bottlenecked by spatial constraints and detachment delays. Here, the authors report a compact annular electrostatic clutch joint with a biphasic amplitude‐frequency modulation strategy to rapidly mitigate residual polarization ...

Unveiling Graphitic Carbon Nitride in Hexagonal Boron Nitride Epitaxy on Sapphire

open access: yesSmall, EarlyView.
Understanding how crystallographic orientation transfers across weakly bonded 2D/3D interfaces is fundamental for van der Waals materials epitaxy. This study reveals that an interfacial graphitic carbon nitride (g‐C3N4) layer plays a pivotal role in aligning hexagonal boron nitride on sapphire.

Recent advances in polymeric chemically amplified positive resists: Materials and design strategies

open access: yesSmart Molecules, EarlyView.
This review summarizes recent advances in the molecular design of positive chemically amplified resists, focusing on photoacid generators and polymer architectures. Key strategies for enhancing sensitivity—including self‐amplification effects, copolymerization of sensitive monomers, controlled polymerization, and photosensitized chemically amplified ...
