A clever elimination strategy for efficient minimal solvers

open access: yes, 2017
We present a new insight into the systematic generation of minimal solvers in computer vision, which leads to smaller and faster solvers. Many minimal problem formulations are coupled sets of linear and polynomial equations where image measurements enter

Higgs induced FCNC as a source of new physics in $b\to s $ transitions

open access: yes, 2009
The observations in the $B_{s}$ sector suggest the existence of some new physics contribution to the $B_S-\bar{B}_s$ mixing. We study the implications of a hypothesis that this contribution is generated by the Higgs induced flavour changing neutral ...

Higher Order Derivatives in Costa's Entropy Power Inequality [PDF]

open access: yes, 2015
Let $X$ be an arbitrary continuous random variable and $Z$ be an independent Gaussian random variable with zero mean and unit variance. For $t~>~0$, Costa proved that $e^{2h(X+\sqrt{t}Z)}$ is concave in $t$, where the proof hinged on the first and second
