We study topological von Neumann regularity and principal von Neumann regularity of Banach algebras. Our main objective is comparing these two types of Banach algebras and some other known Banach algebras with one another. In particular, we show that the class of topologically von Neumann regular Banach algebras contains all $C^*$-algebras, group algebras of compact abelian groups and ...

BACKGROUND Traditional cardiovascular risk factors do not explain the high incidence of cardiovascular mortality and morbidity in patients with end-stage renal disease. A prothrombotic state could accelerate the process of vascular disease in these patients. METHODS In this study, four platelet activation markers (NAP-2, P-selectin, GP1b and RANTES) and two endothelial cell activation markers...

The Shannon entropy of a collection of random variables is subject to a number of constraints, the best-known examples being monotonicity and strong subadditivity. It remains an open question to decide which of these “laws of information theory” are also respected by the von Neumann entropy of many-body quantum states. In this article, we consider a toy version of this difficult problem by anal...

Dieser Artikel behandelt Modellierung als wesentlichen Bestandteil eines zeitgemäßen Unterricht insbesondere in strukturund naturwissenschaftlichen Fächern. Wir präsentieren das Rahmensystem Cool Modes, in das eine Vielzahl von Modellierungsumgebungen integriert sind, die miteinander kombiniert werden können. Dieses Rahmensystem fügt sich in gewachsene Unterrichtsformen ein und erweitert die Mö...

Do we desire something because it has value? Or is the value of a thing a consequence of the fact that it is desired? To adopt the former alternative is to involve oneself in the task of providing a theory of value which would make value a property things have as it were prior to their serving as objects of desire. Theories of this sort have been developed inter alia by Meinong, Nicolai Hartman...

THE ophthalmological symptoms of von Recklinghausen's syndrome are numerous. Multiple tumours of the superficial nerves may cause a plexiform neurofibromatosis, preferably situated in the superior eyelid and the region around the orbit. The intra-orbital and the ciliary nerves can also be affected. Defects in the bony orbital wall may cause a pulsating exophthalmos, and phakomata in the iris an...

One of the biggest threats to dignity human person which characterizes today’s thinking is reduction one constitutive aspect: body, subjectivity, relationality, and like. Based on philosophy Dietrich von Hildebrand, paper demonstrates how six false dichotomies a similar kind are resolved, namely: spirit substance relation, subjectivity objectivity, Eigenleben transcendence, affectivity rational...

Abstract Background and Aims:‎ Von Willebrand disease is a bleeding disorder caused by quantitative or functional defects in von Willebrand factor. The disease is found in up to 1 percent of the population. The most common symptom is mucocutaneous bleeding. Recently, studies conducted on healthy people showed that the H817Q mutation that previously known to cause von Willebrand...
