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

From Darboux-Egorov system to bi-flat $F$-manifolds

open access: yes, 2012
Motivated by the theory of integrable PDEs of hydrodynamic type and by the generalization of Dubrovin's duality in the framework of $F$-manifolds due to Manin [22], we consider a special class of $F$-manifolds, called bi-flat $F$-manifolds. A bi-flat $F$-

An Investigation of Equivalence Principle Violations Using Solar Neutrino Oscillations in a Constant Gravitational Potential

open access: yes, 1996
Neutrino oscillations induced by a flavor-dependent violation of the Einstein Equivalence Principle (VEP) have been recently considered as a suitable explanation of the solar electron-neutrino deficiency.

Local Isometric immersions of pseudo-spherical surfaces and evolution equations

open access: yes, 2015
The class of differential equations describing pseudo-spherical surfaces, first introduced by Chern and Tenenblat [3], is characterized by the property that to each solution of a differential equation, within the class, there corresponds a 2-dimensional ...

Sex‐dimorphic gene regulation in murine macrophages across niches

open access: yesImmunology &Cell Biology, EarlyView.
In this study, we perform a meta‐analysis of new and publicly available RNA‐seq datasets from male and female mouse macrophages across eight niches to identify conserved sex‐dimorphic gene expression patterns. We found that three sex chromosome‐linked genes are always differentially expressed between males and females: Ddx3y, Eif2s3y and Xist. However,
