We present a measurement of the electron spectrum from inclusive semileptonic B decay, using 5.1 fb−1 of Υ(4S) data collected with the Belle detector. A high-momentum lepton tag was used to separate the semileptonic B decay electrons from secondary decay electrons. We obtained the branching fraction, B(B → Xe+ν) = (10.90 ± 0.12 ± 0.49)%, with minimal model dependence. From this measurement, we ...
یکی از حقوق توأم با مقررات آمرۀ اشخاص حقیقی، جواز تغییر تابعیت آن هاست. به موجب مادۀ 588 قانون تجارت، شخص حقوقی می تواند دارای کلیۀ حقوق و تکالیفی شود که قانون برای افراد قائل است؛ مگر حقوق و وظایفی که بالطبع فقط انسان ممکن است دارای آن باشد، مانند حقوق و وظایف ابوت و بنوت. در قوانین موضوعۀ ایران قانون گذار برخلاف اشخاص حقیقی هیچ نص قانونی را به طور عام در خصوص تغییر تابعیت اشخاص حقوقی و به ویژ...
A new series of 4-aryl-1, 4-dihyropyridines possessing potent calcium channel blocking activity along with good vasodilatory profile by the modified Hantzsch condensation using trifluoroacetic acid as catalyst has been synthesized and reported from our laboratory. The present work describes chemo enzymatic approach for the enantioselective hydrolysis of a 1, 4dihydropyridine skeleton. In this s...
Heart failure (HF) is a debilitating cardiac syndrome characterized by dyspnea, poor exercise tolerance, and chronic fatigue along with high morbidity and mortality. Heart failure may be defined as the pathophysiologic state in which the heart is incapable of pumping a sufficient supply of blood to meet the metabolic requirements of the body or requires elevated ventricular filling pressures to...
We report four novel position angle measurements of the core region M81* at 5GHz and 8GHz, which confirm presence sinusoidal jet precession M81 as suggested by \cite{Marti-Vidal2011}. The model makes three testable predictions on evolution precession, we test in our data with observations 2017, 2018, 2019. Our confirms a period $\sim7~\mathrm{yr}$ top small linear drift. further show that two 8...
