Systematic Benchmarking of a Noise‐Tolerant Conductive Hydrogel Electrode for Epidermal Bioelectronics

Advanced Science, EarlyView.
General schematic of the approach. Abstract Conventional Silver/Silver Chloride (Ag/AgCl) electrodes remain the clinical standard for electrophysiological monitoring but are hindered by poor skin conformity, mechanical rigidity, and signal degradation, particularly under motion or sweat.

Modeling of ultrasound transducers

, 2010
This Ph.D. dissertation addresses ultrasound transducer modeling for medical ultrasound imaging and combines the modeling with the ultrasound simulation program Field II. The project firstly presents two new models for spatial impulse responses (SIR)s to a rectangular elevation focused transducer (REFT) and to a convex rectangular elevation focused ...

Ultrasound Modulation of Visual Circuits in Mice Independent of Auditory Confound

Advanced Science, EarlyView.
In this study, Qiu et al. found that low‐intensity ultrasound can directly activate sparse ultrasound‐sensitive neurons (UNs) in the primary visual cortex (V1) of deafened mice. The proportion of these sparse UNs is pressure‐dependent. Furthermore, ultrasound modulates visual circuitry with distinct excitatory and inhibitory effects.

A Testis‐Specific Aralkylamine N‐Acetyltransferase Regulates Dimorphic Sperm Function and Male Fertility in Moths

Advanced Science, EarlyView.
We identify a Lepidoptera‐conserved testis‐specific arylalkylamine N‐acetyltransferase (LTNAT) that governs male moth fertility via a novel mechanism. LTNAT loss disrupts eupyrene sperm mitochondrial derivatives and impairs apyrene sperm motility, offering a safe molecular target for innovative pesticides and genetic pest control.
