We report a novel high-power bistable distributed feedback (DFB) semiconductor laser diode operating near 1060 nm, which is realized by inserting a high-bandgap electron barrier layer and a grating layer in a super large V-Neck optical cavity laser design.Optical and electrical bistable characteristics are both observed for this device.An on-state
The global increasing trend in total greenhouse gas emissions in recent decades has triggered the need for climate-related development financing.This study analyzes the effects of climate-related development mitigation finance and renewable Hinges energy consumption on greenhouse gas emissions in the Congo Basin.Using panel data from 2002 to 2020,
Abstract Background Infection with varicella-zoster virus (VZV) contemporaneously with malignant disease or immunosuppression represents a particular challenge and requires individualized decisions and treatment.Although the increasing use of varicella-vaccines in the general population and rapid initiation of VZV-immunoglobulins and acyclovir in c
The cancer stem cell (CSC) concept is a highly debated topic in cancer research.While experimental evidence in favor of the cancer stem cell theory is apparently abundant, the results are often criticized as being difficult to interpret.An important reason for this is that most experimental data that support this model rely on transplantation studi
