In this paper, we propose a formal de nition of temporal validity which we believe is the rst and the most comprehensive quanti cation of that notion. The temporal validity is developed into the notion of sort of validity with which the confusion among various time concepts introduced for temporal databases can be dispelled. Further, we discuss the problem of preserving multiple past states of ...
in this paper, two pairs of new inequalities are given, which decompose two hilbert-type inequalities.
Background: An obvious gradient in health outcomes has been implicated in many evidences relating to social and economic factors. Proper data are requested to convince policy-makers calling for intersectoral action for health. Recently, I.R. of Iran has come up with 52 health equity indicators to monitor health equity through the country. Conducting regular surveys on 14 out of 52 national heal...
In this paper, we study the semi-stable twisted holomorphic vector bundles over compact Gauduchon manifolds. By using Uhlenbeck–Yau's continuity method, show that existence of approximate Hermitian–Einstein structure and semi-stability are equivalent As its application, Bogomolov type inequality is also valid for a bundle.
In a recent paper [Linear Algebra Appl., 461:92--122, 2014], Tao et al. proved an analog of Thompson's triangle inequality for simple Euclidean Jordan algebra by using case-by-case analysis. this short note, we provide direct proof that is valid on any algebras.

The principal result of this paper is a Remez-type inequality for Müntz polynomials: p(x) := n ∑ i=0 aix λi , or equivalently for Dirichlet sums: P (t) := n ∑ i=0 aie i, where (λi) ∞ i=0 is a sequence of distinct real numbers. The most useful form of this inequality states that for every sequence (λi) ∞ i=0 satisfying ∞ ∑ i=0 λi 6=0 1 |λi| < ∞ there is a constant c depending only on (λi) ∞ i=0,...
We study the mixing inequalities which were introduced by Günlük and Pochet (2001). We show that a mixing inequality which mixes n MIR inequalities has MIR rank at most n if it is a type I mixing inequality and at most n− 1 if it is a type II mixing inequality. We also show that these bounds are tight for n = 2. Given a mixed-integer set PI = P ∩ Z(I) where P is a polyhedron and Z(I) = {x ∈ Rn ...
We consider a stochastic network interdiction problem in which the goal is to detect an evader, who selects a maximum-reliability path. Subject to a resource constraint, the interdictor installs sensors on a subset of the network’s arcs to minimize the value of the evader’s maximum-reliability path, i.e., to maximize the detection probability. When this decision is made, the evader’s origin–des...
The principal result of this paper is a Remez-type inequality for M untz polynomials: p(x) := n X i=0 a i x i ; or equivalently for Dirichlet sums: P(t) := n X i=0 a i e ? i t ; where (i) 1 i=0 is a sequence of distinct real numbers. The most useful form of this inequality states that for every sequence (i) 1 i=0 satisfying 1 X i=0 i 6 =0 1 j i j < 1 there is a constant c depending only on (i) ...
