Association of advanced lung cancer inflammation index with all-cause and cardiovascular mortality in US patients with asthma
Published 2025-06-01Get full textBackgroundAsthma poses a significant global health challenge, representing a chronic respiratory disorder marked by airway inflammation. The advanced lung cancer inflammation index (ALI) served as a comprehensive index to assess inflammation. However, few studies have investigated the association be...

True Phase Measurement of Distributed Vibration Sensors Based on Heterodyne $\varphi $-OTDR
Published 2018-01-01Get full textWe demonstrate a method to truly measure the phase change originated from external vibration by heterodyne phase-sensitive optical time-domain reflectometer (<inline-formula><tex-math notation="LaTeX">$\varphi $</tex-math> </inline-formula>-OTDR). The method of diff...

Generation of the First-Order OAM Modes in Ring Fibers by Exerting Pressure Technology
Published 2017-01-01Get full textWe have proposed an effective method of generating the first-order orbital angular momentum (OAM) modes in ring fibers. The first-order OAM modes (<inline-formula><tex-math notation="LaTeX">${\rm{L = \pm 1}}$</tex-math> </inline-formula>) can be represented as the l...

All-Fiber Multiplexing and Transmission of High-Order Circularly Polarized Orbital Angular Momentum Modes With Mode Selective Couplers
Published 2019-01-01Get full textWe have demonstrated an all-fiber high-order circularly polarized (CP) orbital angular momentum (OAM) modes (de)multiplexing system based on second-order mode selective couplers (SMSCs). Such SMSCs combining standard single mode fiber and ring core fiber (RCF) are fabricated by a fusing and pulling...

Muscle‐Derived Small Extracellular Vesicles Mediate Exercise‐Induced Cognitive Protection in Chronic Cerebral Hypoperfusion
Published 2025-07-01Get full textAbstract Physical exercise protects against cognitive impairment caused by chronic cerebral hypoperfusion (CCH). However, the mechanisms through which exercise sends signals from the periphery to the central nervous system remain incompletely understood. This study demonstrated that exercise promote...
