Insulin sensitivity is determined by complex metabolic interactions dictated by a multitude of inputs that include inherited genetic and epigenetic determinants as well as many varying modifiers such ...
There are many interesting questions one can ask about a highly symmetric graph. A graph with a transitive automorphism group can be obtained starting with a group G and a small set S of generators....
In this paper we consider the problem of how to computationally test whether a matrix inequality is positive semidefinite on a semialgebraic set. We propose a family of sufficient conditions using the...
We prove a normalized version of the restricted invertibility principle obtained by Spielman-Srivastava. Applying this result, we get a new proof of the proportional Dvoretzky-Rogers factorization the...
Abstract: A $Z$-set in a metric space $X$ is a closed subset $K$ of $X$ such that each map of the Hilbert cube $Q$ into $X$ can uniformly be approximated by maps of $Q$ into $X \setminus K$. The aim o...
We show that integrable involutive maps, due to the fact they admit three integrals in separated form, can give rise to equations which are consistent around the cube and which are not in the multiaf...

We prove that a random group has fixed points when it isometrically acts on a CAT(0) cube complex. We do not assume that the action is simplicial.
For a knot K the cube number is a knot invariant de ned to be the smallest n for which there is a cube diagram of size n for K.
A general method for obtaining a trigonometric-type interpolating equation for the eight-point cubical array is illustrated. It can often be used to reproduce a ninth datum at an arbitrary point near ...
The symmetric group S3 acts on S 2 × S 2 × S 2 by coordinate permutation, and the quotient space (S 2×S 2×S 2)/S3 is homeomorphic to the complex projective space CP 3.In this paper.
A 2-coloring of the n-cube in the n-dimensional Euclidean space can be considered as an assignment of weights of 1 or 0 to the vertices. Such a colored n-cube is said to be balanced if its center of m...
Right now, 10 to 15 Rubik’s Cube-sized satellites are orbiting high above Earth. Known as cube satellites, or “CubeSats,” the devices help researchers conduct simple space observations and measure cha...
用化学镀的方法制备了CuBe/绝缘层/NiCoP复合结构丝,用2 A直流电流退火2 min.研究了退火对样品巨磁阻抗效应的影响,发现退火大幅度提高了样品的巨磁阻抗效应,最大磁阻抗比率ΔZ/Z由制备态时的42.3%提高到693.1%,增加了15.4倍.利用复数磁导率和等效电路研究了样品的磁化特性,并对电流退火增强复合结构丝巨磁阻抗效应的机理作了分析.电流退火消除内应力且改变样品的磁结构,使得退火样品...
