We consider a class of subcritical superprocesses (Xt)t≥0 with general spatial motions and branching mechanisms. study the asymptotic behaviors Qt,r, distribution Xt conditioned on Xt+r not being null measure. first give existence limt→∞Qt,r limr→∞Qt,r, then show that an LlogL-type condition is equivalent to iterated limits: limr→∞limt→∞Qt,r limt→∞limr→∞Qt,r. Finally, when holds, we those limit...

torsades de pointes is a rare but potentially lethal arrhythmia which mainly occurs in the setting of a prolonged qt interval. ecg is a reliable tool to detect such abnormalities, routinely taken from all patients over 40 who undergo surgery. we describe the case of a 35-year-old woman with torsades de points arrhythmia after hysterectomy surgery. most likely, our patients had long qt syndrome ...

In this paper, we study the Chebyshev centres of bounded subsets of normed spaces and obtain a norm inequality for relative centres. In particular, we prove that if T is a remotal subset of an inner product space H, and F is a star-shaped set at a relative Chebyshev centre c of T with respect to F, then llx - qT (x)1I2 2 Ilx-cll2 + Ilc-qT (c) 112 x E F, where qT : F + T is any choice functi...

INTRODUCTION It was aimed to calculate QT intervals in patients with acromegaly and to reveal its correlation between QT intervals, and growth hormone and insulin like growth factor-1. MATERIAL AND METHODS Forty-one patients with acromegaly were enrolled into the study. Another 41 individuals with similar features, such as comorbid diseases, age and sex constituted the control group. The elec...
