Understanding the computational complexity of manipulation in elections is arguably the most central agenda in Computational Social Choice. One of the influential variations of the the problem involves a coalition of manipulators trying to make a favorite candidate win the election. Although the complexity of the problem is well-studied under the assumption that the voters are weighted, there w...

BACKGROUND AND OBJECTIVE Delayed cord clamping (DCC) is recommended for premature infants to improve blood volume. Most preterm infants are born by cesarean delivery (CD), and placental transfusion may be less effective than in vaginal delivery (VD). We sought to determine whether infants <32 weeks born by CD who undergo umbilical cord milking (UCM) have higher measures of systemic blood flow t...

BACKGROUND Most Brazilian schools do not have a continuous program for drug use prevention and do not conduct culturally adapted activities for that purpose. This study evaluated the impact of the Unplugged program on drug use prevention among children and adolescents in public middle schools of Brazil. METHODS A non-randomized controlled trial was conducted in 2013 with 2185 students in 16 p...

The Use Case Map (UCM) scenario notation can be used to model service requirements and high-level designs for reactive and distributed systems. It is then a natural candidate for use in the process of generating requirement-directed test suites. We survey several approaches for deriving test goals from UCM models. We distinguish three main approaches. The first approach is based on testing patt...

In a companion study (Layton AT and Layton HE. Am J Physiol Renal Physiol 289: F1346-F1366, 2005), a region-based mathematical model was formulated for the urine concentrating mechanism (UCM) in the outer medulla (OM) of the rat kidney. In the present study, we quantified the sensitivity of that model to several structural assumptions, including the degree of regionalization and the degree of i...

Human postural sway during stance arises from coordinated multi-joint movements. Thus, a sway trajectory represented by a time-varying postural vector in the multiple-joint-angle-space tends to be constrained to a low-dimensional subspace. It has been proposed that the subspace corresponds to a manifold defined by a kinematic constraint, such that the position of the center of mass (CoM) of the...

With the influx of deepfake and style transfer technology in today's news social media, everyone is told that these applications are powered by artificial intelligence deep learning, but too often explanation how it works goes no further. Rather than waiting until second semester computer science grad school to learn about generative adversarial networks (GANs), we propose a classroom activity ...

We provide a mathematical analysis of the spectrum of the linear stability problem for one and two layer channel flows of the upper-convected Maxwell (UCM) and Oldroyd-B fluids at zero Reynolds number. For plane Couette flow of the UCM fluid, it has long been known (Gorodstov and Leonov, J. Appl. Math. Mech. (PMM) 31 (1967) 310) that, for any given streamwise wave number, there are two eigenval...

Özet. Karmaşık yazılım-yoğun sistemlerin davranışını betimlemek ve anlamak amacıyla kullanılan yöntemlerden biri Kullanım Eşlemesi (Use Case Map UCM) gösterimidir. Gereksinimler ve kullanım durumları doğrultusunda ortaya çıkan senaryoları mimari bileşenlerle eşleştirmek, dolayısıyla sistem davranışlarını daha iyi açıklamak ve analiz etmek amacıyla UCM kullanılır. Bu çalışmada ise örnek çoklu or...
