Large Mode Area Single Mode Fiber with a Twisted Polygon-Shaped Core

Photonics, 2022
We present numerical studies on twisted polygon-shaped core fibers for achieving single mode operation with a large mode area propagation in this paper. These large mode area fibers can achieve single mode operation due to twisting-induced high losses to

Mode-locked dysprosium fiber laser: picosecond pulse generation from 2.97 to 3.30 {\mu}m

, 2018
Mode-locked fiber laser technology to date has been limited to sub-3 {\mu}m wavelengths, despite significant application-driven demand for compact picosecond and femtosecond pulse sources at longer wavelengths.

A waveguide polarization toolset design based on mode beating [PDF]

, 2011
A toolset of waveguide elements is examined, which can be combined to produce polarization functional devices in a single contiguous waveguide. In particular, waveguide implementations of an optical isolator and a polarization modulator are discussed ...

Reference ranges for fetal tricuspid and mitral annular plane systolic excursions

Journal of Perinatal Medicine
Echocardiography is the standard tool for assessing fetal cardiac function. Tricuspid annular plane systolic excursion (TAPSE) and mitral annular plane systolic excursion (MAPSE) are simple, reliable indicators of systolic function.

Use of M‐mode echocardiography in clinical pharmacology. [PDF]

British Journal of Clinical Pharmacology, 1979
M-mode echocardiography is a method of using pulsed ultrasound to detect the position and movement of intracardiac structures. The technique itself, and its use in the study of left ventricular disease has been described in a number of recent monographs and reviews (Feigenbaum, 1976; Roelandt, 1977; Mason and Fortuin, 1978).

Deep Sequencing of FLT3‐ITD Enables Response Evaluation and Post‐Treatment Monitoring in Childhood AML: An Exploratory Study

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Background An internal tandem duplication in the gene encoding Fms‐like tyrosine kinase 3 (FLT3‐ITD) is associated with high relapse risk and poor prognosis in acute myeloid leukemia (AML) and plays a crucial role in treatment decisions. Measurable residual disease (MRD) analysis of FLT3‐ITD during and after treatment has shown prognostic ...
