A random-matrix theory of the number sense. [PDF]
Philos Trans R Soc Lond B Biol Sci, 2017 Number sense, a spontaneous ability to process approximate numbers, has been documented in human adults, infants and newborns, and many other animals. Species as distant as monkeys and crows exhibit very similar neurons tuned to specific numerosities. How number sense can emerge in the absence of learning or fine tuning is currently unknown.

Unitary matrix integral for two-color QCD and the GSE-GUE crossover in random matrix theory
Physics Letters B, 2021 We analytically evaluate a unitary matrix integral which appears in the low-energy limit of two-color QCD at finite chemical potential. The result is expressed as a pfaffian. We illustrate its application to the GSE-GUE crossover in random matrix theory.

Massive-scale gene co-expression network construction and robustness testing using random matrix theory. [PDF]
PLoS ONE, 2013 The study of gene relationships and their effect on biological function and phenotype is a focal point in systems biology. Gene co-expression networks built using microarray expression profiles are one technique for discovering and interpreting gene ...

Interpolation between Airy and Poisson statistics for unitary chiral non-Hermitian random matrix ensembles [PDF]
, 2010 We consider a family of chiral non-Hermitian Gaussian random matrices in the unitarily invariant symmetry class. The eigenvalue distribution in this model is expressed in terms of Laguerre polynomials in the complex plane.

Prediction of Solar Ultraviolet Radiations Using Random Matrix Theory
Frontiers in Biomedical Technologies, 2023 Purpose: The correlation of different samples can be described by analytical models such as random matrix theory. In this study, we tried to describe the correlation of different types of ultraviolet values in different months, weeks, and hours to get a

Path Counting and Random Matrix Theory [PDF]
The Electronic Journal of Combinatorics, 2003 We establish three identities involving Dyck paths and alternating Motzkin paths, whose proofs are based on variants of the same bijection. We interpret these identities in terms of closed random walks on the halfline. We explain how these identities arise from combinatorial interpretations of certain properties of the $\beta$-Hermite and $\beta ...

Analysis of the Global Banking Network by Random Matrix Theory
Frontiers in Physics, 2021 Since the financial crisis of 2008, the network analysis of financial systems has attracted a lot of attention. In this paper, we analyze the global banking network via the method of Random Matrix Theory. By applying that method on a cross border lending
