Spin-flip dark excitons are optical-dipole-forbidden quasiparticles with remarkable potential in optoelectronics, especially when they are realized within cleavable Field Bib van der Waals materials.Despite this potential, dark excitons have not yet been definitively identified in ferromagnetic van der Waals materials.Here, we report two dark excit
Introduction Noninvasive positive pressure ventilation (NIPPV) plays an important role in the management of respiratory failure.However, since the emergence of the COVID-19 pandemic, utilization of traditional face mask NIPPV has been curtailed in part due to risk of aerosolization of respiratory particles and subsequent health care worker exposure
The development of adaptive and intelligent clamping devices allows for the reduction of rejects and defects based on weld discontinuities in laser-beam welding.The utilization of fixture-integrated sensors and actuators is a new approach, realizing adaptive clamping devices FACE CREAM that enable in-process data acquisition and a time-dependent ad
Abstract Background Colorectal cancer (CRC) is the second leading cause of cancer-related death in men and women.Systemic disease with metastatic spread to distant sites such as the liver reduces the survival rate considerably.The aim of this study was to investigate the changes in gene expression that occur on invasion and expansion of CRC cells w
Abstract The aim of this study is to evaluate the Nicaraguan screening program for congenital hypothyroidism in terms of coverage and effectiveness of detection and confirmation of cases with the condition throughout a decade.Thyrotropin was quantified in cord-blood samples by a Cooking validated ELISA and a cut-off of 20 mU/l was applied.Coverage,
