When two quantifiers Q1 and Q2 satisfy the scheme Q1x Q2y φ → Q2y Q1x φ, we say that Q1 is scopally dominant over Q2. This relation is central in analyzing and computing entailment relations between different readings of ambiguous sentences in natural language. This paper reviews the known results on scope dominance and mentions some open problems.
Let X1,…,Xn be independent and identically distributed random vectors in Rd. Suppose EX1=0, Cov(X1)=Id, where Id is the d×d identity matrix. further that there exist positive constants t0 c0 such Eet0|X1|≤c0<∞, |⋅| denotes Euclidean norm. W= ∑i=1nXi∕n let Z a d-dimensional standard normal vector. Q symmetric definite matrix whose largest eigenvalue 1. We prove for 0≤x≤εn1∕6, P(|Q1∕2W|>x) P(|Q1∕...
Let q1 and q2 belong to a certain class of normalized analytic univalent functions in the open unit disk of the complex plane. Sufficient conditions are obtained for normalized analytic functions p to satisfy the double subordination chain q1(z)≺ p(z)≺ q2(z). The differential sandwich-type result obtained is applied to normalized univalent functions and to Φ-like functions.
The antihypertensive flavonol quercetin (Q1) is endowed with a cardioprotective effect against myocardial ischemic damage. Q1 inhibits angiotensin converting enzyme activity, improves vascular relaxation, and decreases oxidative stress and gene expression. However, the clinical application of this flavonol is limited by its poor bioavailability and low stability in aqueous medium. In the aim to...
Risk of asthma associated with energy-dense but nutrient-poor dietary pattern in Taiwanese children.
Childhood asthma has rapidly increased over the past few decades, possibly due to changes in lifestyle and dietary patterns. We aimed to determine associations between dietary patterns and asthma in schoolchildren in Taiwan. The Nutrition and Health survey in Taiwan Elementary School Children was carried out by using a multi-staged complex sampling design. A total of 2,082 elementary school chi...
Let T1, . . . , Td be homogeneous trees with degrees q1 + 1, . . . , qd + 1 ≥ 3, respectively. For each tree, let h : Tj → Z be the Busemann function with respect to a fixed boundary point (end). Its level sets are the horocycles. The horocyclic product of T1, . . . , Td is the graphDL(q1, . . . , qd) consisting of all d-tuples x1 · · ·xd ∈ T1×· · ·×Td with h(x1) + · · ·+ h(xd) = 0, equipped wi...
We consider systems comprised of two interlacing M/M/ • /• type queues, where customers of each queue are the servers of the other queue. Such systems can be found for example in file sharing programs, SETI@home project, and other applications (see e.g. Arazi, Ben-Jacob and Yechiali (2005)). Denoting by Li the number of customers in queue i (Qi), i = 1, 2, we assume that Q1 is a multi-server fi...
