Optimal design problems for quasidisks and partially clamped drums: Existence, symmetrization, and numerical methods
… frequency of a circular drum is solved using symmetrization. The gradient of the tone of the drum with respect to the design is considered and approximated appropriately. This approximate gradient is then used to compute examples numerically.

Moser-Trudinger And Adams Type Inequalities And Their Applications
… of these inequalities relied crucially on the symmetrization arguments in the literature. By proposing new arguments and approaches, we develop successfully the critical versions of these well-known inequalities in many different settings where the rearrangement arguments may not be existed. As …

A concentration inequality based statistical methodology for inference on covariance matrices and operators
… concentration based confidence sets: Rademacher symmetrization. The symmetrization inequality, which arises in the probability in Banach spaces literature, is shown to be connected with optimal transport theory and specifically the Wasserstein distance. This insight is used to improve the …

Single-crystal X-ray diffraction at extreme conditions in mineral physics and material sciences
… the unit cell volume (by ~ 11%) and provokes symmetrization of the hydrogen bonds that was deduced from the analysis of the interatomic distances in the Fe(O…H)3(OH)3 moiety. The hydrogen bond symmetrization linked with the high-spin to low-spin crossover in Fe3+ was detected for the first …

SUPPRESSION OF ELECTRON THERMAL CONDUCTION IN THE HIGH β INTRACLUSTER MEDIUM OF GALAXY CLUSTERS
… The overlap of resonances leads to effective symmetrization of the electron distribution function and a strong suppression of heat flux. The results suggest that thermal conduction in the ICM might be strongly suppressed. In a numerical model with continually supplied heat flux in the system, …

Comparison Theorems in Elliptic Partial Differential Equations with Neumann Boundary Conditions
<p>In this thesis, we study how the solution of a PDE changes when the data are rearranged. Specifically, we prove comparison theorems on spherical shells, spheres, and hemispheres, showing that under rearrangement of the data, the solution's convex mean increases. We also obtain similar weighted …
