in the present study conducted at a tertiary care level during the period from 2000-2009, the proportion of birth weight (≥2.5 kg) of new born babies was 80.8%, low birth weight (<2.5 kg) of new born babies was 19.2%. of the new born babies, proportion of very low birth weight (<2 kg) was 6.9%. in this study, sex wise difference in the proportion of low birth weight new born babies was not sign...

For a prime p and a matrix A ∈ Zn×n, write A as A = p(A quo p)+ (A rem p) where the remainder and quotient operations are applied element-wise. Write the p-adic expansion of A as A = A[0] + pA[1] + p2A[2] + · · · where each A[i] ∈ Zn×n has entries between [0, p − 1]. Upper bounds are proven for the Z-ranks of A rem p, and A quo p. Also, upper bounds are proven for the Z/pZ-rank of A[i] for all ...

Low-rank matrix recovery addresses the problem of recovering an unknown low-rank matrix from few linear measurements. Nuclear-norm minimization is a tractable approach with a recent surge of strong theoretical backing. Analagous to the theory of compressed sensing, these results have required random measurements. For example, m ≥ Cnr Gaussian measurements are sufficient to recover any rank-r n ...
