We show that in the framework of the pinch technique the universal part of the parameter can be meaningfully de ned, beyond one loop. The universal part so obtained satis es the crucial requirements of gauge-independence, niteness, and process-independence, even when subleading contributions of the top quark are included. The mechanism which enforces the aforementioned properties is explained i...

In order to minimize the initial energy storage of tens MA-class Z-pinch accelerators, an intelligent optimization method was developed based on transmission line code circuit model and PSOGSA algorithm. Using several input parameters, four overall parameters accelerator could be fast determined, including connection parallel combination LTD cavities, outer radius stack-MITL system, electrical ...

For certain classes of holomorphic correspondences which are matings between Kleinian groups and polynomials, we prove the existence of pinching deformations, analogous to Maskit’s deformations of Kleinian groups which pinch loxodromic elements to parabolic elements. We apply our results to establish the existence of matings between quadratic maps and the modular group, for a large class of qua...

In this HELIOS benchmark simulation, a spherical capsule embedded in a low-density CH2 foam is imploded by an external radiation field. The parameters utilized in this benchmark simulation are taken from z-pinch-driven dynamic hohlraum experiments performed at the Z facility at Sandia National Laboratories [1]. The time-dependent hohlraum radiation field is constrained by on-axis XRD and bolome...
