SPATIAL VARIABILITY OF THE ASPECT SENSITIVITY OF VHF RADAR ECHOES IN THE TROPOSPHERE AND LOWER STRATOSPHERE DURING JET STREAM PASSAGES

Spatial variability of the aspect sensitivity of VHF radar echoes in the troposphere and lower stratosphere during jet stream passages

The aspect sensitivity of SOUSY-VHF-radar oblique-beam echoes from the troposphere and lower stratosphere has been examined for a number of jet stream passages during the years 1990 - 1992.When the core of the jet is overhead or nearly so, vertical profiles of the aspect sensitivity display two notable features.First, the distinction between mainly

Stem cell-derived cardiomyocytes expressing a dominant negative pacemaker HCN4 channel do not reduce the risk of graft-related arrhythmias

BackgroundHuman pluripotent stem cell-derived cardiomyocytes (hPSC-CMs) show tremendous promise for cardiac regeneration following myocardial infarction (MI), but their transplantation gives rise to transient ventricular tachycardia (VT) in large-animal MI models, representing a major hurdle to translation.Our group previously reported that these a

Genetic engineering of cotton with a novel cry2AX1 gene to impart insect resistance against Helicoverpa armigera

Embryogenic calli of cotton (Coker310) were cocultivated with the Agrobacterium tumefaciens strain LBA4404 harbouring the codon-optimised, chimeric cry2AX1 gene consisting of sequences from cry2Aa and cry2Ac genes isolated from Indian strains of Bacillus thuringiensis.Forty-eight putative transgenic plants were regenerated, and PCR analysis of thes
