In this article, we give a necessary and sufficient condition for ampleness of semistable vector bundles with vanishing discriminant on smooth projective variety X. As an application, show some special certain ruled surfaces. We prove similar results parabolic ampleness.

brucellosis is a debilitative disease that imposes costs on both economy and society. it is shown that although the vaccine can prevent abortion, it does not provide complete protection against infection. in iran, brucella melitensis is a common causative agent for brucellosis and bp26 protein of this bacterium having a good antigenesity and an important vaccine candidate. in this study b. meli...

From cellphones and PDAs to huge automated call centers, speech recognition is becoming more and more ubiquitous. As demand for automatic speech recognition (ASR) applications increases, so too does the need to run ASR algorithms on a variety of unconventional computer architectures. One such architecture uses a vector processor, which has many beneets in terms of performance, power consumption...

Vector part i t ion functions appear in m a n y areas of mathemat ics and its applications, including representat ion theory [ 9 ] , commuta t ive algebra [ 14], approximat ion theory [ 4 ] and statistics [5 ] . It was shown by Blakley [ 2 ] that there exists a finite decomposi t ion of N d such that ~b A is a polynomial of degree n d on each piece. Here we describe such a decomposi t ion expli...

We prove necessary and sufficient conditions for a rational vector field on (C∗)n to be complete.
