Annals of Clinical and Translational Neurology, EarlyView.ABSTRACT Objective Intravenous thrombolysis (IVT) before thrombectomy for ischemic stroke may alter clot structure and procedural performance. We investigated how IVT relates to thrombectomy metrics across stroke etiologies. Methods We performed a time‐to‐event analysis of consecutive patients with anterior circulation large vessel occlusion (acLVO ...

Intermodal Four-Wave Mixing In A Higher-Order-Mode Fiber [PDF]
, 2013 Much effort has gone into the study of silica and its material properties due to its importance in long distance communication. Especially, the propagation of optical pulses in single-mode fibers and their interplay with nonlinear effects have been ...

Mode-Field Radius of Photonic Crystal Fibers Expressed by the V-parameter
, 2003 We numerically calculate the equivalent mode-field radius of the fundamental mode in a photonic crystal fiber (PCF) and show that this is a function of the V-parameter only and not the relative hole size.

Annals of Clinical and Translational Neurology, EarlyView.ABSTRACT Objective Considerable efforts have been dedicated to developing effective treatments for post‐stroke executive impairment (PSEI), among which repetitive transcranial magnetic stimulation (rTMS) has shown great potential. This study aimed to investigate the therapeutic effects of high‐frequency rTMS on working memory (WM) and response ...

Harnessing Fungal Biowelding for Constructing Mycelium‐Engineered Materials
Advanced Engineering Materials, EarlyView.Mycelium‐bound composites (MBCs) offer low‐carbon alternatives for construction, yet interfacial bonding remains a critical challenge. This review examines fungal biowelding as a biocompatible adhesive, elucidating mycelium‐mediated interfacial mechanisms and their role in material assembly. Strategies to optimize biowelding are discussed, highlighting

Few-mode Erbium-doped Fiber Amplifier
13th International Conference on Fiber Optics and Photonics, 2016 Few-mode fiber is emerging as an attractive option in an SDM system. EDFA for a few-mode fiber has an issue of differential modal gain (DMG) among its modes. We present EDFA designs to obtain customized DMG.
