A novel higher order finite-element technique based on generalized curvilinear hexahedra with hierarchical curl-conforming polynomial vector basis functions is proposed for microwave modeling. The finite elements are implemented for geometrical orders from 1 to 4 and field-approximation orders from 1 to 10 in the same Galerkin-type finite-element method and applied to eigenvalue analysis of arb...
We construct an algebraic distributive lattice D that is not isomorphic to the congruence lattice of any lattice. This solves a long-standing open problem, traditionally attributed to R. P. Dilworth, from the forties. The lattice D has compact top element and אω+1 compact elements. Our results extend to any algebra possessing a polynomially definable structure of a joinsemilattice with largest ...
This paper presents a performance analysis of optical burst switching (OBS) networks with ring and chordal ring topologies. The performance analysis considers signaling protocols with one-way reservation schemes, being focused on the following protocols: just-in-time (JIT), Jumpstart, JIT+, justenough-time (JET) and Horizon. It is shown that for a network with 20 nodes, the nodal degree gain du...
1. Phosphorus content was measured in adult insects and arachnids from 170 species collected in the Sonoran Desert. 2. Across insect body sizes spanning four orders of magnitude, phosphorus content was inversely related to body mass. The largest species ( ∼ 1 g dry) had phosphorus contents that were only about 60% (0·62% P absolute) as high as phosphorus contents of the smallest species ( ∼ 0·0...
We describe a new exact solver for the minimization of open stacks problem (MOSP). By combining nogood recording with a branch and bound strategy based on choosing which customer stack to close next, our solver is able to solve hard instances of MOSP some 5-6 orders of magnitude faster than the previous state of the art. We also derive several pruning schemes based on dominance relations which ...
We solve an open problem of Diaconis that asks what are the largest orders of pn and qn such that Zn, the pn× qn upper left block of a random matrix Γn which is uniformly distributed on the orthogonal group O(n), can be approximated by independent standard normals? This problem is solved by two different approximation methods. First, we show that the variation distance between the joint distrib...
A priority queue is a data type where the element with the smallest key value can be found and deleted, and new elements can be inserted. It is also called a priority queue when the element with the largest key value is wanted, instead of the smallest. In some cases, it is interesting to find and delete both the smallest and the largest element, as well as to be able to insert new elements. A s...
Screen-based futures markets are gaining trading volumes at the expense of traditional open outcry floor markets. In comparison with open outcry trading – used on the Chicago Board of Trade (CBOT), the world largest futures market – electronic markets offer enhanced transparency, and greater access to users, who can enter orders directly. Screen markets can also maintain strict time priorities ...
background: low compliance with drugs regimens in diabetic patients is one of the greatest challenges in the treatment of diabetes. the aim of this study was to evaluate compliance with medical orders in diabetic patients referred to the endocrinology clinic of afzalipour hospital, kerman, iran. methods: in this cross sectional study 345 of the 3000 patients, who referred to the endocrinology c...
