Scalable Large Field‐of‐view 3D Photoacoustic Ultrasound Imaging With Digital Multiplexing for Human Extremities

Laser &Photonics Reviews, EarlyView.
A digitally multiplexed, large‐aperture photoacoustic and ultrasound imaging architecture is presented to overcome the fundamental limited‐view artifact inherent in conventional arrays. By significantly broadening the structural detection coverage, this scalable platform enables high‐fidelity 3D visualization of human extremities within a single ...

Low‐Crosstalk Silicon Photonic Switch Fabrics for AI Datacenters and High‐Capacity Optical Interconnects: Device‐Level Origins and Mitigation

Laser &Photonics Reviews, EarlyView.
Scaling silicon photonic switch fabrics for AI datacenters is fundamentally constrained by accumulated crosstalk, insertion loss, and device‐level non‐idealities. This work establishes a device‐to‐link‐to‐system framework that connects the physical origins of crosstalk to practical mitigation strategies across device, circuit, and control levels.

Orthostatic Myoclonus—Clinical and Electrophysiological Features in a Large Retrospective Cohort

Movement Disorders Clinical Practice, EarlyView.
Abstract Background Orthostatic myoclonus is characterized by irregular, lower limb myoclonic bursts during stance and is a major cause of postural instability and falls. However, studies are limited, and little is known about its pathophysiology. Objectives We sought to define the clinical and electrophysiological features of orthostatic myoclonus in ...

Deep CNN-based detection of cardiac rhythm disorders using PPG signals from wearable devices.

PLoS ONE
Cardiac rhythm disorders can manifest in various ways, such as the heart rate being too fast (tachycardia) or too slow (bradycardia), irregular heartbeats (like atrial fibrillation-AF, ventricular fibrillation-VF), or the initiation of heartbeats in ...

Unraveling Pathway Complexity in Photoreversible Supramolecular Hydrogels: Real‐Time Visualization and Sub‐Micrometric Photopatterning

Small, EarlyView.
This research demonstrates real‐time visualization of supramolecular sol‐gel transitions using Fluorescence Lifetime Imaging Microscopy (FLIM). By leveraging 5D visualization, integrating 3D space, time, and polarity resolution, we achieved maskless sub‐micrometric photopatterning within the gel matrix.

Estimating the Common Output Cycle in Australia

Australian Economic Review, EarlyView.
ABSTRACT Background/Objective This study develops a statistical measure of Australia's common output cycle and investigates the extent to which cyclical fluctuations are shared across industries. It also evaluates whether the common output cycle provides useful information for forecasting inflation.

Design of a triple band-pass balanced filter based on single-stepped-impedance ring resonator with ultra-wide stopband bandwidth

ETRI Journal
In this study, a new tri-band balanced band-pass filter (BPF) design based on a single-stepped-impedance ring resonator (SIRR) with four stepped stubs loaded on the feeding structure was proposed, analyzed, and design equations were derived.
