Real roots of hypergeometric polynomials via finite free convolution

We examine two binary operations on the set of algebraic polynomials, known as multiplicative and additive finite free convolutions, specifically in the context of hypergeometric polynomials. We show that the representation of a hypergeometric polynomial

Decompositions of the free additive convolution

Journal of Functional Analysis, 2007
We introduce and study a new type of convolution of probability measures called the orthogonal convolution, which is related to the monotone convolution. Using this convolution, we derive alternating decompositions of the free additive convolution of compactly supported probability measures in free probability. These decompositions are directly related

Design of microprocessor-based hardware for number theoretic transform implementation [PDF]

, 1983
Number Theoretic Transforms (NTTs) are defined in a finite ring of integers Z (_M), where M is the modulus. All the arithmetic operations are carried out modulo M.

Retinex-based low-light image enhancement with multi-channel feature optimization

Science Progress
Low-light conditions reduce brightness and contrast, obscure structural details, and amplify noise, which degrades visual quality and adversely affects downstream tasks, such as object detection and segmentation.

Thrifty wide-context models of B cell receptor somatic hypermutation

eLife
Somatic hypermutation (SHM) is the diversity-generating process in antibody affinity maturation. Probabilistic models of SHM are needed for analyzing rare mutations, understanding the selective forces guiding affinity maturation, and understanding the ...
