BACKGROUND Atherosclerotic occlusion of a coronary vessel is the commonest cause of ischaemic heart disease. The distribution of atherosclerotic lesions is not random,with stenoses preferentially situated at branch ostia, bifurcation points, and the proximal segments of daughter vessels. The aim of this study was to determine the effect of the intrinsic anatomical properties of the left main co...

· AIM: To quantify corneal ultrastructure using laser scanning confocal microscopy (IVCM) in patients with keratoconus and control subjects. · METHODS: Unscarred corneas of 78 keratoconic subjects without a history of contact lens use and 36 age-matched control subjects were evaluated with slitlamp examination (SLE), corneal topography and laser scanning IVCM. One eye was randomly chosen for an...

In this paper, the concept of fraction tree is introduced. This has profound consequences both in mathematical sub-disciplines and other branches science technology. we shall witness connection with that Fibonacci sequence relate terms continued fractions.

In October 2011, a snowstorm in the northeastern USA caused many branch failures of many tree species commonly planted in urbanized settings. Immediately following the storm, we assessed 1,764 trees for possible snow-induced damage and factors affecting it on the campus of the University of Massachusetts in Amherst, MA, USA. Nearly all failures were of branches, most of which were not defective...

Closed form expressions for the capacity of multiple antenna systems in the presence of Rayleigh flat fading is derived for two sub-optimal adaptive transmission schemes, namely channel inversion (CI) and truncated channel inversion (TCI), assuming channel state information (CSI) is available at both the transmitter and the receiver. Moreover, an upper bound for the capacity of a multiple-input...

In this paper, one of the most popular and reliable Workflow Management Systems Oracle Workflow System is used for automation of a typical faculty business – organization of a scientific conference. Four main branches of the organization are detached into four sub-workflows and explained in details. Joined they create a structure and give a formal model able to support organization of a confere...
