during a period of four years between june, is, 1988 to june, is, 1992 one hundred and fourteen patients with congestive heart failure (chf) were admitted to the pediatric department of taleghani general hospital. during the above period, 192 patients with heart disease were hospitalized at this department and chf was the cause of admission in 59.4% of them. congenital heart disease (cho) was t...
With a sample of approximately 89 x 10(6) B(-)B pairs collected with the BABAR detector, we perform a search for B meson decays into pairs of charmless vector mesons (phi, rho, and K*). We measure the branching fractions, determine the degree of longitudinal polarization, and search for CP violation asymmetries in the processes B+-->phiK(*+), B0-->phiK(*0), B+-->rho(0)K(*+), and B+-->rho(0)rho(...
The Pollard ρ algorithm is a widely used algorithm for solving discrete logarithms on general cyclic groups, including elliptic curves. Recently the first nontrivial runtime estimates were provided for it, culminating in a sharp O( √ n) bound for the collision time on a cyclic group of order n [4]. In this paper we show that for n satisfying a mild arithmetic condition, the collisions guarantee...
OBJECTIVE To assess ecological models to describe infant mortality rate in Ceara (Northeastern Brazil) in two different periods of time. METHODS This was a cross-sectional ecologic study of two years, 1991 and 2000, using non-matching information per municipalities. Estimates on the infant mortality rate of the Instituto de Pesquisas Econômicas Aplicadas (Institute of Applied Economic Researc...
Abstract Background Transabdominal bowel ultrasound (TABUS) is a non-invasive tool that can be used to assess inflammation in ulcerative colitis (UC). It particularly attractive for use children, given the need general anesthesia when undergoing endoscopic assessment of inflammation. A standardized TABUS scoring system UC has only been developed adults (the Intestinal Ultrasound (UC-IUS) Index)...
We prove collision bounds for the Pollard rho algorithm to solve the discrete logarithm problem in a general cyclic group G. Unlike the setting studied by Kim et al., we consider additive walks: the setting used in practice to solve the elliptic curve discrete logarithm problem. Our bounds differ from the birthday bound O. p jGj/ by a factor of p log jGj and are based on mixing time estimates f...
We prove that the relation $E_0(\rho, W^{-}) + E_0(\rho, W^{+}) \geq 2 E_0(\rho, W)$ holds for any binary input discrete memoryless channel $W$, and $\rho \geq 0$.
OBJECTIVES To assess the validity of the BASRI and m-SASSS scores for the radiological axial involvement in psoriatic arthritis (PsA). Secondary end-points were to report on clinical, functional and radiographic characteristics of axial involvement. METHODS Inclusion criteria were satisfaction of the CASPAR criteria and the presence of clinical, functional and/or radiological axial involvemen...
