UNLABELLED Ventilation-perfusion (V/Q) SPECT has been reported to improve the diagnostic performance of V/Q imaging for the diagnosis of pulmonary embolism (PE). However, only sparse data based on an objective reference test are available, and the criteria used for interpretation have varied widely. Therefore, the aim of our study was to assess the performance of V/Q SPECT using various criteri...

The Maximum Independent Set problem is NP-hard and remains NP-hard for graphs with maximum degree three (also called subcubic graphs). In our talk we will study its complexity in hereditary subclasses of subcubic graphs. Let A r q be the graph consisting of an induced cycle C q and an induced path with r edges having an endvertex in common with the C q , where A 1 4 is known as the banner. Our ...

A program to simulate the production of heavy quarks through the boson-gluon fusion process in ep collisions is presented. The full electroweak structure of the electron–gluon interaction is taken into account as well as the masses of the produced heavy quarks. Higher order QCD radiation is treated using initial and final state parton showers, and hadronization is performed using the Lund strin...

A function f (X 1 ; X 2 ; : : : ; X n) is said to be t th-order correlation-immune if the ran-ally, if all possible outputs are equally likely, then f is called a t ?resilient function. In this paper, we provide three diierent characterizations of t th-order correlation immune functions and resilient functions where the random variable is over GF (q). The rst is in terms of the structure of a c...

Over its evolutionary history, Saccharomyces cerevisiae has evolved to be well-adapted to fluctuating nutrient availability. In the presence of sufficient nutrients, yeast cells continue to proliferate, but upon starvation haploid yeast cells enter stationary phase and differentiate into nonquiescent (NQ) and quiescent (Q) cells. Q cells survive stress better than NQ cells and show greater viab...

We investigate the local integrability in C3 of some three-dimensional Lotka–Volterra equations at the origin with (p : q : r)-resonance, ẋ = P = x(p+ ax+ by + cz), ẏ = Q = y(q + dx+ ey + fz), ż = R = z(r + gx+ hy + kz). Recent work on this problem has centered on the case where the resonance is of “rank-2”. That is, there are two independent linear dependencies of p, q and r over Q. Here, we c...

Abstract Let $E$ be an elliptic curve defined over a number field $K$, let $\alpha \in E(K)$ point of infinite order, and $N^{-1}\alpha $ the set $N$-division points in $E(\overline {K})$. We prove strong effective uniform results for degrees Kummer extensions $[K(E[N],N^{-1}\alpha ): K(E[N])]$. When $K=\mathbb Q$, under minimal (necessary) assumption on $, we show that inequality $[\mathbb Q(E...

Consider a sequence of n independent observations from a population of increasing size αi, i = 1,2,... and an absolutely continuous initial distribution function. The distribution of the kth record value is represented as a countable mixture, with mixing the distribution of the kth record time and mixed the distribution of the nth order statistic. Precisely, the distribution function and (pow...

We present a new algebraic method for solving the inverse problem of quantum scattering theory based on Marchenko theory. applied triangular wave set equation kernel expansion in separable form. The form allows reduction to system linear equations. For zero orbital angular momentum, expression coefficients is obtained terms Fourier series function depending momentum $q$ and determined by data f...

We give a complete conjectural formula for the number $e_r(d,m)$ of maximum possible ${\mathbb{F}}q$-rational points on projective algebraic variety defined by $r$ linearly independent homogeneous polynomial equations degree $d$ in $m+1$ variables with coefficients finite field ${\mathbb{F}}q$ $q$ elements, when $d<q$. It is shown that this holds affirmative several values $r$. In general case,...
