The Commutant of L(h) in Its Ultrapower May or May Not Be Trivial
Kirchberg asked in 2004 whether the commutant of L(H) in its (norm) ultrapower is trivial. Assuming the Continnuum Hypothesis, we prove that the answer depends on the choice of the ultrafilter. Let H be a separable infinite dimensional complex Hilbert space, fixed throughout. The purpose of this paper is to prove that, assuming the Continnuum Hypothesis, the commutant of L(H) (the algebra of bo...
متن کاملAdipoRon may be benefit for atherosclerosis prevention
Atherosclerosis has serious role in coronary arteries disease,so it is important to establish effective strategies for prevention or even treatment of atherosclerosis. Adiponectin, as one of the most abundant adipokines, has insulin sensitivity, anti-inflammatory and anti-atherogenic properties. Disturbed adiponectin actions through its receptor, (AdipoR1 and AdipoR2) may be involved in atheros...
متن کاملThe climate envelope may not be empty.
A recent paper (1) purported to document negligible climatic determination among European bird species, with implications for forecasting range shifts in changing climates. However, only 12 of 100 species analyzed were endemic—thus, for the remaining 88% of test species, key limits with likely climatic determination were excluded, particularly eastward and southward (2). Second, the authors dev...
متن کاملAnimals may not be stuck in time !
Humans have the ability to mentally travel forward and back in time. They can retrieve vivid memories of past events (episodic memories) and can imagine the future (planning). Although it has been suggested that this is a uniquely human ability, the evidence for subjective time travel in humans is typically based on verbal report and elaboration. Such evidence cannot be obtained from animals. H...
متن کاملIL-8 May Be the Target of Arsenic in Human Breast Milk
Background and Aims: The critical aim of this study was to evaluate the effects of breast-milk contamination with Nickel and Arsenic, as well as aflatoxin M1 (AFM1) on the milk levels of IL-6 and IL-8. Materials and Methods: Breast milk was collected from 76 mothers on the 30th day post-parturition and milk levels of AFM1, Nickel, Arsenic, IL-6 and IL-8 were evaluated. Results: The results s...
