Data‐Driven Multi‐Objective Optimization of Large‐Diameter Si Floating‐Zone Crystal Growth

Advanced Theory and Simulations, Volume 9, Issue 2, February 2026.
This study presents a surrogate‐based Multi‐Objective Optimization framework for Floating Zone silicon crystal growth. An ensemble of Neural Networks is trained on simulation data and combined with Genetic Algorithms to explore trade‐offs in process parameters.

Sharp commutator estimates of all order for Coulomb and Riesz modulated energies

Communications on Pure and Applied Mathematics, Volume 79, Issue 2, Page 207-292, February 2026.
Abstract We prove functional inequalities in any dimension controlling the iterated derivatives along a transport of the Coulomb or super‐Coulomb Riesz modulated energy in terms of the modulated energy itself. This modulated energy was introduced by the second author and collaborators in the study of mean‐field limits and statistical mechanics of ...

Dimer models and conformal structures

Communications on Pure and Applied Mathematics, Volume 79, Issue 2, Page 340-446, February 2026.
Abstract Dimer models have been the focus of intense research efforts over the last years. Our paper grew out of an effort to develop new methods to study minimizers or the asymptotic height functions of general dimer models and the geometry of their frozen boundaries.

A Generalized Integer Gamma Distribution as an Asymptotic Replacement for a Logbeta Distribution & Applications

American Journal of Mathematical and Management Sciences, 2003
SYNOPTIC ABSTRACTThe use of the concept of near-exact distribution enables us to obtain distributions which are very close to the exact distribution but which are far more manageable. Indeed such near-exact distributions are usually far more accurate than any of the usual asymptotic distributions, being thus much useful in the computation of quantiles ...

A mixture of Generalized Integer Gamma distributions as the exact distribution of the product of an odd number of independent Beta random variables: applications

Journal of Interdisciplinary Mathematics, 2006
In this paper we show first how the distribution of the logarithm of a random variable with a Beta distribution may be expressed either as a mixture of Gamma distributions or as a mixture of Generalized Integer Gamma (GIG) distributions and then how the exact distribution of the product of an odd number of independent Beta random variables whose first ...

Mixed RF/FSO Cooperative Relaying Systems With Co-Channel Interference

IEEE Transactions on Communications, 2018
In this paper, we provide a global framework analysis of a dual-hop mixed radio frequency (RF)/free space optical (FSO) system with multiple branches/relays wherein the first and second hops, respectively, consist of RF and FSO channels. To cover various

Coverage and Rate Analysis in Downlink ${L}$ -Tier HetNets With Fluctuating Beckmann Fading

IEEE Wireless Communications Letters, 2019
The fluctuating Beckmann (FB) fading is a general fading model, and it extends the $\kappa $ - $\mu $ shadowed fading to a power imbalance scenario. However, the FB fading contains a generalized Lauricella confluent hypergeometric function, which makes
