(abridged) Variability is a key property of stars on the asymptotic giant branch (AGB). Their pulsation period related to luminosity and mass-loss rate (MLR) star. Long-period variables (LPVs) Mira are most prominent all types variability evolved stars. However, reddest, obscured AGB too faint in optical have eluded large surveys. Our goal obtain sample LPVs with MLRs by analysing WISE W1 W2 li...

We consider the problem of Graphical lasso with an additional l∞ element-wise norm constraint on the precision matrix. This problem has applications in high-dimensional covariance decomposition such as in [Janzamin and Anandkumar, 2012a]. We propose an ADMM algorithm to solve this problem. We also use a continuation strategy on the penalty parameter to have a fast implemenation of the algorithm...

background: routine oocytes cryopreservation remained an elusive technique in the wide ranges of available assisted reproductive technologies. the microtubules of oocytes are vulnerable to cryoprotectants and thermal change during cryopreservation. objective: the effects of a vitrification protocol were investigated on the spindle and chromosome configurations of mice oocytes cryopreserved at t...

We numerically verify that the non-symmetric interior penalty Galerkin method and the Oden-Babus̆ka-Baumann method have sub-optimal convergence properties when measured in the L-norm for odd polynomial approximations. We provide numerical examples that use piece-wise linear and cubic polynomials to approximate a second-order elliptic problem in one and two dimensions.

This thesis is devoted to dense deformable image registration/fusion using discrete methods. The main contribution of the thesis is a principled registration framework coupling iconic/geometric information through graph-based techniques. Such a formulation is derived from a pair-wise MRF view-point and solves both problems simultaneously while imposing consistency on their respective solutions....
