We study the points of strong subdifferentiability for the norm of a real JB∗-triple. As a consequence we describe weakly compact real JB∗-triples and rediscover the Banach-Stone Theorem for complex JB∗-triples.
in the first chapter we study the necessary background of structure of commutators of operators and show what the commutator of two operators on a separable hilbert space looks like. in the second chapter we study basic property of jb and jb-algebras, jc and jc-algebras. the purpose of this chapter is to describe derivations of reversible jc-algebras in term of derivations of b (h) which are we...
BACKGROUND This study aimed to determine the risk of thromboembolic events in patients with junctional bradycardia(JB). METHODS We retrospectively reviewed electrocardiograms(ECGs) for 380,682 patients. Those with JB on an ECG at least twice over a ≥3-month interval were included for analysis. We additionally included 138 CHADS2 score-matched patients(age, 68.4 ± 15.7 years; male, 52.2%) in s...
in this note, we characterize chebyshev subalgebras of unital jb-algebras. we exhibit that if b is chebyshev subalgebra of a unital jb-algebra a, then either b is a trivial subalgebra of a or a= h r .l, where h is a hilbert space
At age 58, JB began memorising Milton's epic poem Paradise Lost. Nine years and thousands of study hours later, he completed this process in 2001 and recalled from memory all 12 books of this 10,565-line poem over a 3-day period. Now 74, JB continues to recite this work. We tested his memory accuracy by cueing his recall with two lines from the beginning or middle of each book and asking JB to ...
Brinjal (Solanum melongena L.), belongs to the family Solanaceae, which is an important vegetable crop of sub-tropics and tropics. The present investigation was carried out at Vegetable Research Demonstration Block, College Horticulture, VCSG UUHF, Bharsar, during Kharif, 2017 evaluate diverse germplasm brinjal under mid hill conditions. experiment laid in RCBD with three replications. In this ...
