For regression models with functional responses and scalar predictors, it is common for the number of predictors to be large. Despite this, few methods for variable selection exist for function-on-scalar models, and none account for the inherent correlation of residual curves in such models. By expanding the coefficient functions using a B-spline basis, we pose the function-on-scalar model as a...

We address here a few classical lattice spin models, involving n-component unit vectors (n=2,3), associated with a D-dimensional lattice Z(D),D=1,2, and interacting via a pair potential restricted to nearest neighbors and being isotropic in spin space, i.e., defined by a function of the scalar product between the interacting spins. When the potential involves a continuous function of the scalar...
This report considers low resolution scalar quantization. Specifically, it considers entropyconstrained scalar quantization for memoryless Gaussian and Laplacian sources with both squared and absolute error distortion measures. The slope of the operational rate-distortion functions of scalar quantization for these sources and distortion measures is found. It is shown that in three of the four c...
For the inflaton field we determine a new exact solution by using Lie symmetry analysis. Specifically, construct second-order differential master equation for arbitrary scalar potential assuming that spectral index density perturbations $n_{s}$ and to tensor ratio $r$ are related as $n_{s}-1=h\left( r\right) $. Function $h\left( $ is classified according admitted symmetries equation. The possib...
We derive an exact wormhole spacetime supported by a phantom scalar field in the context of $f({\sf R})$ gravity. Without specifying form function, self-interacts with mass term potential that is derived from equation and resulting model purely it free ghosts avoids tachyonic instability.

We consider noncommutative analogs of scalar electrodynamics and N = 2 D = 4 SUSY Yang-Mills theory. We show that one-loop renormalizability of noncommutative scalar electrodynamics requires the scalar potential to be an anticommutator squared. This form of the scalar potential differs from the one expected from the point of view of noncommutative gauge theories with extended SUSY containing a ...
Starting out from the most general, gauge invariant and renormalizable scalar potential of the Rparity violating MSSM and performing a calculable rotation to the scalar fields we arrive at the so called Grossman-Haber basis where the sneutrino VEVs are zero. The advantage of our rotation is that, in addition, we obtain diagonal soft supersymmetry breaking sneutrino masses and all potential para...
We study second-order nonlinear periodic systems driven by the vector p-Laplacian with a nonsmooth, locally Lipschitz potential function. Under minimal and natural hypotheses on the potential and using variational methods based on the nonsmooth critical point theory, we prove existence theorems and amultiplicity result. We conclude the paper with an existence theorem for the scalar problem, in ...
