Micro-Doppler Effect of Extended Streamlined Targets Based on Sliding Scattering Centre Model [PDF]

open access: yesRadioengineering, 2016
The scattering center of extended streamlined targets can slide when the direction of radiation is changed. The sliding scattering center has influence on the micro-Doppler effect of micro-motion of the extended streamlined target.

A Method for the Micro-Motion Signal Separation and Micro-Doppler Extraction for the Space Precession Target

open access: yesIEEE Access, 2020
Aiming at the problem of micro-motion signal separation and micro-Doppler extraction of the precession target, a new method based on singular value decomposition (SVD) and joint approximate diagonalization of eigen-matrices (JADE) is proposed in this ...

Computational fluid dynamics simulations of airflow through the nasal passages of rhinolophoid bats

open access: yesThe Anatomical Record, EarlyView.
Abstract The nasal passages of bats that emit their echolocation call through their nostrils have adapted for sound emission as well as standard respiratory and olfactory functions. Rhinolophids, hipposiderids and rhinonycterids all use a high duty cycle (HDC) echolocation strategy.

Maximizing Neurovascular Outcomes of Facial Transplantation: A Comprehensive Review

open access: yesClinical Anatomy, EarlyView.
ABSTRACT Facial transplantation is a division of reconstructive surgery which aims to improve the function and appearance of a face that has endured severe disfigurement. Currently, the face transplant procedure uses allogenic tissue, harvested from a brain‐dead donor, to replace damaged facial components.

A 1D Cascaded Denoising and Classification Framework for Micro-Doppler-Based Radar Target Recognition

open access: yesRemote Sensing
Micro-Doppler signatures play a crucial role in capturing target features for the radar classification task, and the time–frequency distribution method is widely used to represent micro-Doppler signatures in many applications including human activities ...

Unveiling the Microvasculature: The Index of Microcirculatory Resistance and Its Expanding Role in Cardiovascular Care

open access: yesCatheterization and Cardiovascular Interventions, EarlyView.
ABSTRACT Index of microcirculatory resistance (IMR) is a cutting‐edge, wire‐based tool that advances the capability assessment of coronary microvascular function. By utilizing distal coronary pressure and mean transit time under maximal hyperemia, IMR delivers consistent, reproducible insights into the microvasculature's dynamic health.

Micro-Doppler Ambiguity Resolution Based on Short-Time Compressed Sensing

open access: yesJournal of Electrical and Computer Engineering, 2015
When using a long range radar (LRR) to track a target with micromotion, the micro-Doppler embodied in the radar echoes may suffer from ambiguity problem.

Informed acceptance and perceptions of the 2025 ILAE seizure classification following structured teaching

open access: yesEpileptic Disorders, EarlyView.
Abstract Objective To assess informed acceptance and perceptions of the 2025 update of the International League Against Epilepsy (ILAE) seizure classification—after participants had received a focused educational introduction to the updated classification. Methods We analyzed anonymized live poll responses from two educational webinars dedicated to the

Operational assessment and adaptive selection of micro‐Doppler features

open access: yesIET Radar, Sonar & Navigation, 2015
A key challenge for radar surveillance systems is the discrimination of ground‐based targets, especially humans from animals, as well as different types of human activities. For this purpose, target micro‐Doppler signatures have been shown to yield high automatic target classification rates; however, performance is typically only given for near‐optimal
