Flavanols from chocolate appear to increase nitric oxide bioavailability, protect vascular endothelium, and decrease cardiovascular disease (CVD) risk factors. We sought to test the effect of flavanol-rich dark chocolate (FRDC) on endothelial function, insulin sensitivity, beta-cell function, and blood pressure (BP) in hypertensive patients with impaired glucose tolerance (IGT). After a run-in ...

The time course of the rate of oxygen consumption (QO2) after a single flash of light has been measured in 300-micrometers slices of drone retina at 22 degrees C. To measure delta QO2(t), the change in QO2 from its level in darkness, the transients of the partial pressure of O2 (PO2) were recorded with O2 microelectrodes simultaneously in two sites in the slice and delta QO2 was calculated by a...

The Dirac delta function has solid roots in 19th century work in Fourier analysis by Cauchy and others, anticipating Dirac’s discovery by over a century.

Let $H \xrightarrow{s} G$ denote that any edge-coloring of $H$ by $s$ colors contains a monochromatic $G$. The degree Ramsey number $r_{\Delta}(G;s)$ is defined to be $\min \{ \Delta(H): H G \}$, and the bipartite $br_{\Delta}(G;s)$ \textrm{ } \chi(H) = 2 \}$. In this note, we show $r_{\Delta}(K_{m,n};s)$ linear on $n$ with fixed $m$. We also evaluate for paths other trees.

In the present investigation, inspired by work on Yamaguchi type class of analytic functions satisfyingthe criteria $\mathfrak{Re}\{\frac{f (z)}{z}\} > 0, $ in openunit disk $\Delta=\{z \in \mathbb{C}\colon |z|<1\}$ and making use S\v{a}l\v{a}gean-difference operator, which is a special Dunkl operator with constant $\vartheta$ $\Delta$ , wedesignate definite new classes $\mathcal{R}_{\lam...

a question of the existence of delta-convergent sequences that vanish at the support of the limit Dirac delta function and gave an example of sequences of this type. It is a sequence of even functions that don't have a compact support. Motivated by the question in this paper we develop some results concerning delta sequences and show more examples of delta sequences of the type with or without ...

Kalman adaptive filtering was applied for the first time, to our knowledge, to the real-time simultaneous determination of water isotopic ratios using laser absorption spectroscopy at 2.73 microm. Measurements of the oxygen and hydrogen isotopologue ratios delta(18)O, delta(17)O, and delta(2)H in water showed a 1-sigma precision of 0.72 per thousand for delta(18)O, 0.48 per thousand for delta(1...

Due to the fabrication architecture employed—flat s(ubstrate) versus sharp t(ip), chemisorption physisorption, etc–, self assembled monolayers (SAMs) break forward-backward invariance even in case of homometal molecular junctions; they induce changes electrodes' work function different from each other ( Δ Φ s ≠ t $ \Delta \Phi _{\text{s}} \ne _{\text{t}}$ ). Because differences > translate into...
