Info-Gap is purported to be a new theory for decision-making under severe uncertainty. Its claim to fame is that it is non-probabilistic in nature and thus offers an alternative to all current theories for decision-making under uncertainty. In this essay I examine this theory from an Operations Research point of view. I show that: · Info-Gap is neither new nor radically different from current d...

DP-bioglass paste has been demonstrated to produce 60 microm of sealing depth on exposed dentinal tubules. However, the occlusive effect depended on a continuous placement of DP-bioglass paste on dentinal surface for three days. In a bid to fabricate highly reactive DP-bioglass particles, a sol-gel method was used together with HNO3, NaOH, and H3PO4 as catalysts. As a result, the application ti...

It is well-known that for every N ≥ 1 and d ≥ 1 there exist point sets x1, . . . , xN ∈ [0, 1] whose discrepancy with respect to the Lebesgue measure is of order at most (logN)d−1N−1. In a more general setting, the first author proved together with Josef Dick that for any normalized measure μ on [0, 1] there exist points x1, . . . , xN whose discrepancy with respect to μ is of order at most (lo...

We address the classical issue of appropriate choice of the regularization and discretization level for the Tikhonov regularization of an inverse problem with imperfectly measured data. We focus on the fact that the proper choice of the discretization level in the domain together with the regularization parameter is a key feature in adequate regularization. We propose a discrepancy-based choice...

Prostaglandin (PG)D2, which has long been implicated in allergic diseases, is currently considered to elicit its biological actions through the DP receptor (DP). Involvement of DP in the formation of allergic asthma was recently demonstrated with DP-deficient mice. However, proinflammatory functions of PGD2 cannot be explained by DP alone. We show here that a seven-transmembrane receptor, CRTH2...

The Pósa-Seymour conjecture asserts that every graph on n vertices with minimum degree at least (1−1/(r +1))n contains the r-th power of a Hamilton cycle. Komlós, Sárközy and Szemerédi famously proved for large n. notion discrepancy appears in many areas mathematics, including theory. In this setting, G is given along 2-coloring its edges. One then asked to find copy subgraph discrepancy, i.e.,...

In this paper, we consider a dual-primal FETI (FETI-DP) method for elliptic problems on nonmatching grids. The FETI-DP method is a domain decomposition method that uses Lagrange multipliers to match solutions continuously across subdomain boundaries in the sense of dual-primal variables. We use the mortar matching condition as the continuity constraints for the FETI-DP formulation. We construct...

Assuming the Raising-to-Object analysis of ECM (Bošković, 1997; Lasnik, 1999a, 1999b; Lasnik & Saito, 1991; Postal, 1974), this raises a problem for recent minimalist accounts of Subjacency (e.g., Davies & Dubinsky, 2003; Uriagereka, 1999) that tries to derive the Subject Condition effect in (1), since the DP that receives Accusative Case in (2b) is essentially raised from the embedded clause s...

To determine whether left ventricular (LV) contraction contributes to the generation of right ventricular (RV) systolic pressure in humans, LV and RV pressures and their first derivative (dP/dt) were recorded simultaneously with micromanometer-tipped catheters in 11 conscious subjects. Seven subjects had normal LV and coronary angiograms. Four subjects had moderate LV dysfunction (resting eject...
