Classification of Drones Based on Micro-Doppler Radar Signatures Using Dual Radar Sensors

open access: yesLeida xuebao, 2018
Classification of drones is important due to their increasing popularity and potential threats. The micro-Doppler signatures that depend on the rotation of rotor blades facilitate the classification of drones.

Prediction of incident heart failure in type 2 diabetes mellitus: Rationale and design of the DM‐HEART study

open access: yesJournal of Diabetes Investigation, EarlyView.
ABSTRACT Preclinical heart failure (HF) (stages A and B) is common but easily overlooked in asymptomatic patients with type 2 diabetes (T2D). There is a paucity of evidence regarding how coexisting risk factors contribute to the development of HF in asymptomatic Asian patients with T2D, and there is a lack of guidance on the early identification of ...

Advantages of horizontal centrifugation of platelet‐rich fibrin in regenerative medicine and dentistry

open access: yesPeriodontology 2000, EarlyView.
Abstract The aim of this comprehensive review was to evaluate comparative studies on horizontal and fixed‐angle centrifugation methods for preparing platelet‐rich fibrin (PRF). Furthermore, additional studies utilizing horizontal PRF (H‐PRF) were systematically investigated.

Motion Classification Based on Harmonic Micro-Doppler Signatures Using a Convolutional Neural Network

open access: yesIEEE Journal of Microwaves
We present the design of narrowband radio-frequency harmonic tags and demonstrate their use in the classification of common motions of held objects using harmonic micro-Doppler signatures. Harmonic tags capture incident signals and retransmit at harmonic

Quantifying microvascular responses to local heating using optical coherence tomography: Comparison between skin sites and sex differences

open access: yesExperimental Physiology, EarlyView.
Summary of the study design, metholodgy, results and conclusions. Abstract Due to a lack of technical capacity to directly visualise and quantify microvessels in the skin, little is known regarding regional and/or sex differences. We compared diameter, velocity, flow and density at four regional sites using a novel optical coherence tomography (OCT ...

Prediabetic cardiomyopathy is attenuated by hypothalamic PVN oxytocin neuron activation

open access: yesThe Journal of Physiology, EarlyView.
Abstract figure legend A long‐term high‐fat, high‐fructose diet induces prediabetes with insulin resistance, hyperinsulinaemia, elevated triglycerides and metabolic‐associated steatotic liver disease (MASLD) in male rats. Animals developed prediabetic cardiomyopathy characterized by diastolic dysfunction, interstitial fibrosis and tachycardia ...

Neonatal Wet Gangrene With Early Auto‐Amputation in a Resource‐Limited Setting With Incomplete Etiologic Workup: A Case Report

open access: yesClinical Case Reports, Volume 14, Issue 6, June 2026.
ABSTRACT Neonatal limb gangrene with auto‐amputation is rare and often idiopathic. Early recognition, prompt referral, and thorough etiologic workup—despite resource limitations—are critical. Wet gangrene requires broad‐spectrum antibiotics, wound care, and timely surgical amputation to preserve growth plates and allow future prosthesis fitting.

Limited Sensitivity of Ultrasound‐Guided Fine‐Needle Aspiration Cytology for Occult Nodal Metastases in Early‐Stage Oral Squamous Cell Carcinoma

open access: yesHead &Neck, Volume 48, Issue 6, Page 1620-1629, June 2026.
ABSTRACT Background Ultrasound‐guided fine‐needle aspiration cytology (US‐FNAC) is commonly used in the diagnostic work‐up of head and neck cancer, but its ability to detect occult lymph node metastases in early‐stage oral squamous cell carcinoma (OSCC) with a clinically negative neck remains unclear.

Lithium Niobate Quadratic Integrated Nonlinear Photonics: Enabling Ultra‐Wide Bandwidth and Ultrafast Photonic Engines

open access: yesNanophotonics, Volume 15, Issue 9, 13 May 2026.
This perspective surveys emerging quantum and classical photonic applications across operating wavelengths and timescales, highlighting persistent technological gaps in integrated light sources. We examine the unique advantages of quadratic nonlinear photonics on the thin‐film lithium niobate (TFLN) platform and discuss strategies for realizing ...
