Optical Detuning Strategies for Shielded Loop Resonators

Magnetic Resonance in Medicine, EarlyView.
ABSTRACT Purpose To compare detuning performance and evaluate power requirements of optical detuning methods and to demonstrate feasibility of an optically‐detuned 4‐channel receive array. Methods Four optical detuning methods were compared in simulations, bench tests, and phantom measurements at 3T against conventional galvanic detuning.

In Vitro Reconstruction of Axonal Heat Sensing with a Photothermal Nerve‐on‐a‐Chip

Small, EarlyView.
A photothermal nerve‐on‐a‐chip platform is presented that enables precise, localized heating of sensory axons with simultaneous electrical recording. The system reveals millisecond‐scale dynamics of heat‐evoked neural activity and provides a new approach to study how temperature‐dependent ion channel behavior is translated into axonal firing.

Simple Estimation and Application of the Differential Resistance of a Photovoltaic Module at its Maximum Power Point

IEEJ Transactions on Electrical and Electronic Engineering, EarlyView.
The modulating light irradiation method can estimate the target cell voltage in a working photovoltaic module without electrical contact. This method requires the differential resistances (DRs) of the target cell and module to quantitatively estimate the voltage.

Parallel diode‐clamped linear converter for withstand test and partial discharge measurement of electric equipment

High Voltage, 2023
High‐voltage withstand tests are essential for electric equipment like power transformers, electric cable lines, gas insulated switchgears etc. The partial discharge (PD) measurement for such equipment under applied high voltage is also required at the ...

Evading the blues: Nocturnally active adult Leach's Storm‐Petrels show evidence of avoiding LED lights with shorter wavelengths

Conservation Science and Practice, EarlyView.
Abstract Nocturnal seabirds, particularly Procellariiforms, are vulnerable to being negatively impacted by artificial lights as they are prone to encounter various forms of light pollution in coastal and pelagic habitats, leading to strandings or other changes to their normal behavior.

Unravelling polyphenol skin permeation: A comparative study using full‐thickness 3D in vitro and ex vivo human skin models

International Journal of Cosmetic Science, EarlyView.
This study demonstrates that full‐thickness 3D in vitro skin models reliably assess the permeation of cosmetic polyphenols, revealing compound‐specific transport profiles and bridging the gap between conventional cell models and ex vivo human skin, while offering an ethical and robust alternative for dermal absorption screening. Abstract The evaluation

Three-Phase Diode-Clamped Four-Level PWM Inverter With Offset Voltage Injection

IEEE Access
In this paper, a three-phase diode-clamped four-level PWM inverter with offset voltage injection is proposed. The proposed inverter is based on multi-neighboring reference vector (discontinuous) pulse-width modulation (MNRV (D)PWM), where multiple ...

Alterations to longitudinal muscle morphology and mechanical function following immobilization and recovery in female ovariectomized and intact rats

Experimental Physiology, EarlyView.
Abstract Serial sarcomere number (SSN) is reduced following immobilization of a muscle in a shortened position in male rodents thereby impairing muscle contractile function. However, in female rodents the effects of oestrogen on SSN and mechanical changes following immobilization and re‐ambulation are unknown.

Presentation of preload and afterload to isolated heart preparations

The Journal of Physiology, EarlyView.
Abstract figure legend The heart can be isolated, and when this is so, it must be subjected to loading conditions. Over the past few decades, various loading methods have been developed to prescribe preload and afterload to isolated working‐heart preparations.
