The largest prime factor of $X^3+2$ [PDF]

open access: yes, 2001
The largest prime factor of $X^3+2$ has been investigated by Hooley, who gave a conditional proof that it is infinitely often at least as large as $X^{1+\delta}$, with a certain positive constant $\delta$.

Why is the Milky Way X-factor Constant? [PDF]

open access: yes, 2013
The CO-H2 conversion factor (Xco; otherwise known as the X-factor) is observed to be remarkably constant in the Milky Way and in the Local Group (aside from the SMC). To date, our understanding of why Xco should be so constant remains poor.

Quantum communication complexity of symmetric predicates [PDF]

open access: yes, 2002
We completely (that is, up to a logarithmic factor) characterize the bounded-error quantum communication complexity of every predicate $f(x,y)$ depending only on $|x\cap y|$ ($x,y\subseteq [n]$). Namely, for a predicate $D$ on $\{0,1,...,n\}$ let $\ell_0(

Factor X deficiency: a comment on two recent case studies

open access: yesThe Journal of Haemophilia Practice, 2023
Hereditary factor X deficiency (HFXD) is a rare genetic bleeding disorder, affecting approximately 1 in 1,000,000 individuals globally, and resulting in abnormally low activity of clotting factor X (FX). Diagnosis may occur early in life, particularly in

Farnesoid X receptor and fibroblast growth factor 15/19 as pharmacological targets

open access: yesLiver Research, 2021
The farnesoid X receptor (FXR) is a nuclear receptor and transcriptional regulator activated by bile acids or synthetic FXR agonists. FXR is expressed highly in the liver and intestine where modulation of FXR critically regulates the expression of genes ...
