We have developed fully non-blocking optical matrix switches using a thermo-optic polymer 1 × 2 total-internal-reflection (TIR) switch as a unit switching element. The TIR switch consists of crossed multimode polymer waveguides and an offset heater electrode at the switching node. The fabricated 4 × 4 and 8 × 8 optical matrix switch chips show excellent switching performances. The insertion los...

Let G be a simple graph. An IE-total coloring f of G is a coloring of the vertices and edges of G so that no two adjacent vertices receive the same color. Let C(u) be the set of colors of vertex u and edges incident to u under f . For an IE-total coloring f of G using k colors, if C(u) 6= C(v) for any two different vertices u and v of G, then f is called a k-vertex-distinguishing IE-total-color...

Previous studies have not addressed the effect of differing fat intake on the effectiveness of varying (n-3) polyunsaturated fatty acid (PUFA) ingestion in altering tissue composition and eicosanoid production. This study examined (n-3):(n-6) PUFA ratios of 0, 0.1:1, 0.2:1, 0.4:1, and 1:1 with total fat at 5, 10, 15, and 20 g/100 g of diet and (n-6) PUFA fixed at 1.5 g/100 g of diet on tissue c...

BACKGROUND Hazardous chemicals and their metabolites may accumulate in the body following repeated airborne exposures and skin contact. AIMS To estimate the contribution of skin absorption to total body burden of N,N-dimethylformamide (DMF) across a working week in two groups with similar levels of respiratory exposure but dissimilar skin contact. METHODS Twenty five workers in a synthetic ...

let $m$ be a module over a commutative ring $r$ and let $n$ be a proper submodule of $m$. the total graph of $m$ over $r$ with respect to $n$, denoted by $t(gamma_{n}(m))$, have been introduced and studied in [2]. in this paper, a generalization of the total graph $t(gamma_{n}(m))$, denoted by $t(gamma_{n,i}(m))$ is presented, where $i$ is an ideal of $r$. it is the graph with all elements of $...

A bstract We initiate the analytical functional bootstrap study of conformal field theories with large N limits. In this first paper we particularly focus on 1D O ( ) vector bootstrap. obtain a remarkably simple equation from crossing equations in limit. The numerical bound is saturated by generalized free theories, while its extremal actions do not converge to any non-vanishing functionals equ...
