Optimal Site of the Reference Electrode for Recording the Compound Muscle Action Potential of the Deltoid Muscle

Muscle &Nerve, EarlyView.
ABSTRACT Introduction/Aims For recording the compound muscle action potential (CMAP) of the deltoid muscle, the reference electrode over the acromion (Ac) has been used to avoid contamination of responses from other arm muscles to the distal tendon (DT). A recent article recommended the sternum (St) as the reference electrode.

Ultrabroadband Spacetime Nanoscopy of Terahertz Polaritons in a van der Waals Cavity

Small, EarlyView.
This work introduces SYnchrotron SpaceTimE Mapping (SYSTEM), which captures real‐time evolution of polariton wave packets with ∼10 nm spatial and sub‐100 fs temporal resolution across an ultrabroadband 5 to 50 THz range. Here, SYSTEM directly visualizes the creation, interference, and decay of multiple high‐quality Fabry‐Pérot phonon polariton cavity ...

Fast and Simple Series Resistance Imaging for Tandem Solar Cells Using Differential Luminescence

Solar RRL, EarlyView.
This article presents a method for imaging the series resistance of subcells in a multijunction device. It requires few input properties, no current or voltage calibration and only three measured images. Validated on single junction and multijunction perovskite‐based devices, this method provides a practical tool for advancing photovoltaic research and

Quantizing DNA Metallization for Site‐Defined Growth of Single Quantum Emitters

Small Structures, EarlyView.
Predictive design rules guide DNA origami‐templated synthesis of atomically precise silver nanoclusters. Controlled nucleation yields single emitters with nanometer registration and reproducible fluorescence signatures, paving the way toward programable quantum photonic architectures and nanoscale device integration.

Portable Radar for Noncontact Heart Rate Monitoring and Estrus Detection in Dairy Cows

IEEJ Transactions on Electrical and Electronic Engineering, EarlyView.
This study introduces a portable radar system for real‐time monitoring of respiratory and heart rates in dairy cows. It uses millimeter‐wave Frequency Modulated Continuous Wave (FMCW) radar to perform noncontact physiological sensing, reducing behavioral disturbance. The radar system's design prioritizes portability, cost‐effectiveness, and robustness,

Nanobody–chlorin e6 conjugate for Nectin‐4‐mediated tumor targeting and enhanced photodynamic therapy

VIEW, EarlyView.
Nectin‐4 is frequently overexpressed in solid tumors, yet many PDT photosensitizers show poor water solubility and nonspecific uptake. A Nectin‐4‐targeted nanobody–chlorin e6 conjugate (NPC) improves aqueous solubility and selectively accumulates in Nectin‐4‐positive tumor cells.

Time‐resolved 3D imaging opportunities with XMPI at ForMAX

Journal of Synchrotron Radiation, EarlyView.
The first implementation of X‐ray multi‐projection imaging (XMPI) at the ForMAX beamline (MAX IV) enables the acquisition of multiple projections simultaneously without requiring sample rotation. This approach facilitates volumetric studies of fast dynamics at frame rates of 12.5 kHz with micrometre resolution, with the potential of even higher speeds,

Bandpass Filter Inspired Filtering Patch Antenna

2021 IEEE MTT-S International Wireless Symposium (IWS), 2021
A planar filtering patch antenna inspired by BPF (bandpass filter) prototype is proposed in this paper. The antenna has a very simple structure, while realizing multifunctional operation, including directional radiation and filtering functions. The principle of replacing the LC resonator of BPF prototype with a patch resonator is illustrated. The newly

Inductorless bandpass filters

IEEE Journal of Solid-State Circuits, 1970
The technique of designing inductorless filters by replacing the inductors in conventional LC filters with gyrators and capacitors is considered for the special case of the high-quality channel bandpass filters used in multiplex telephony. One particular gyrator circuit, which has been found to be very satisfactory, using two operational amplifiers and
