Universal microscopic spectrum of the unquenched QCD Dirac operator at finite temperature
Journal of High Energy Physics, 2021 In the ε-regime of chiral perturbation theory the spectral correlations of the Euclidean QCD Dirac operator close to the origin can be computed using random matrix theory.

On pairs of equations with unequal powers of primes and powers of 2
AIMS MathematicsIt is proved that every pair of sufficiently large even integers can be represented in the form of a pair of equations, each containing two squares of primes, two cubes of primes, two biquadrates of primes, and $ 30 $ powers of 2.

Partition Problems in Additive Number Theory
Journal of Number Theory, 1996 Let \(A\) be a subset of integers. Let \[ \sum(A)= \Biggl\{ \sum_{b\in B} b: B\text{ is a non-empty finite subset of }A\Biggr\}. \] Let \(f_k(n)\) be the minimal integer such that if \([f_k(n)]= \bigcup^k_{i=1} A_i\) then \(n\in \bigcup^k_{i= 1}\sum (A_i)\). In a previous paper [\textit{B. Bollobás}, \textit{P. Erdős} and \textit{G.

Sickle Cell Disease Is an Inherent Risk for Asthma in a Sibling Comparison Study
Pediatric Blood &Cancer, EarlyView.ABSTRACT Introduction Sickle cell disease (SCD) and asthma share a complex relationship. Although estimates vary, asthma prevalence in children with SCD is believed to be comparable to or higher than the general population. Determining whether SCD confers an increased risk for asthma remains challenging due to overlapping symptoms and the ...

Genomic breeding value estimation using nonparametric additive regression models
Genetics Selection Evolution, 2009 Genomic selection refers to the use of genomewide dense markers for breeding value estimation and subsequently for selection. The main challenge of genomic breeding value estimation is the estimation of many effects from a limited number of observations.

Stability analysis of five-grade Leishmania epidemic model with harmonic mean-type incidence rate
Advances in Difference Equations, 2021 In this paper, we discuss the Anthroponotic Cutaneous Leishmania transmission. In addition, we develop a mathematical model for the Anthroponotic Cutaneous Leishmania transmission and consider its qualitative behavior. We derive the threshold number R 0 $
