Stochastic exp-concave optimization is an important primitive in machine learning that captures several fundamental problems, including linear regression, logistic regression and more. The exp-concavity property allows for fast convergence rates, as compared to general stochastic optimization. However, current algorithms that attain such rates scale poorly with the dimension n and run in time O...

Information concentration of probability measures have important implications in learning theory. Recently, it is discovered that the information content of a log-concave distribution concentrates around their differential entropy, albeit with an unpleasant dependence on the ambient dimension. In this work, we prove that if the potentials of the log-concave distribution are exp-concave, which i...

This True Experimental study compared academic performance of students in class VIII in initial tryout in one of the English Medium Schools of Vadodara, India among three methods of teaching arithmetic subject viz. (i) Conventional Method (in control group –C), (ii) Computer Assisted Instruction (CAI) only (in Experimental Group A Exp A) and (iii) Computer Assisted Instruction with simultaneous...

Two experiments were conducted to determine if exposure of prepubertal heifers to supplemental lighting hastens the onset of puberty. In Exp. 1, 16 heifers were paired according to birth date (April 21 to July 4) and assigned randomly to exposure to either 18 h light/d (L) or natural photoperiods (N) from 22 wk of age until puberty. Twenty-two heifers in Exp. 2, born between February 27 and Mar...

Exopolysaccharides (EXPs) of Staphylococcus aureus are associated with virulence in animal models. An EXP from the S. aureus strain Smith diffuse was previously detected in 64.3% of S. aureus clinical isolates. EXP was isolated from culture supernatants of this strain after DNAase, RNAase, phosphodiesterase I and lysostaphin treatment, and was further purified by cation-exchange and molecular-s...
