We propose and demonstrate an ultra-wide tunable mode-locked all-fiber laser based on nonlinear amplifying loop mirror (NALM) with the output of cylindrical vector beams (CVBs). The tuning range covers from 1029 nm to 1098 nm through the intracavity nonlinear polarization evolution (NPE) filter effect. The switchable CVBs between radially and azimuthally polarized beams with mode purity above 90% are generated by incorporating a broadband few-mode long-period fiber grating (LPFG).

In this work, we introduce spatial and chemical saturation options for artefact reduction in magnetic resonance fingerprinting (MRF) and assess their impact on T and T mapping accuracy. An existing radial MRF pulse sequence was modified to enable spatial and chemical saturation. Phantom experiments were performed to demonstrate flow artefact reduction and evaluate the accuracy of the T and T maps.

Objectives: Brachial artery injury due to displaced supracondylar fracture (SC) of the humerus in children may present with pink pulseless hand (PPH), denoting a well perfused hand without radial pulse, or acute hand ischemia. Some reports state that brachial artery reconstruction is not necessary in children with persisting PPH, but the reports on long-term consequences such as intermittent claudications, growth retardation and ischemic contracture in children with pulseless hand are scarce and often misinterpreted. The objective of our analysis was to assess the long-term outcomes of children with brachial artery injury associated with SC fracture.

Department of Biomedical Engineering, Toyo University, Kawagoe, Japan.
The purpose of this study was to clarify sex differences in the inhibition of sympathetic vasomotor outflow which is caused by the loading of cardiopulmonary baroreceptors. Ten young males and ten age-matched females participated. The participants underwent a passive leg raising (PLR) test wherein they were positioned supine (baseline, 0º), and their lower limbs were lifted passively at 10º, 20º, 30º, and 40º.

Purpose: This study aims to evaluate the feasibility of structural sub-millimeter isotropic brain MRI at 0.55 T using a 3D half-radial dual-echo balanced steady-state free precession sequence, termed bSTAR and to assess its potential for high-resolution magnetization transfer imaging.
Methods: Phantom and in-vivo imaging of three healthy volunteers was performed on a low-field 0.
