Micro-motion feature extraction of space targets based on sinusoidal frequency modulation Fourier transform

open access: yesThe Journal of Engineering, 2019
The space target can be discriminated from other objects by the micro-motion feature difference. The micro-motion features of a space target with precession include the spinning period, the precession angle and the precession period etc. The main work of

Six‐ and Twelve‐Month Changes in Body Composition and 24‐h Energy Expenditure After a Very Low‐Calorie Ketogenic Diet

open access: yesObesity, EarlyView.
ABSTRACT Objective This study assessed changes in body composition and 24‐h energy metabolism at 6 and 12 months after initiation of a 1‐month very low‐calorie ketogenic diet (VLCKD) in women with obesity. Methods Seventeen women with obesity who completed a 1‐month VLCKD underwent a 4‐week transition phase with carbohydrate reintroduction, followed by

Transcriptomic comparative study between canalicular adenoma and HMGA2::WIF1 canalicular‐like pleomorphic adenoma

open access: yesThe Journal of Pathology, EarlyView.
Abstract Canalicular adenoma (CA) is a benign salivary gland tumor predominantly affecting the upper lip and is characterized by monomorphic epithelial cells arranged in branching cords within a loose and vascularized stroma. Unlike pleomorphic adenoma (PA), CA lacks a chondroid matrix and exhibits specific histological features, such as high cuboidal ...
