Factor X deficiency: a comment on two recent case studies
The 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

Ubiquity of entropies of intermediate factors [PDF]
, 2020 We consider topological dynamical systems $(X,T)$, where $X$ is a compact metrizable space and $T$ denotes an action of a countable amenable group $G$ on $X$ by homeomorphisms. For two such systems $(X,T)$ and $(Y,S)$ and a factor map $\pi : X \rightarrow Y$, an intermediate factor is a topological dynamical system $(Z,R)$ for which $\pi$ can be ...

Nature, 2012 Researchers have plenty of theories about what might cause multiple sclerosis. But for now, the factor that triggers the disease remains elusive.

The hypothesis of path integral duality II: corrections to quantum field theoretic results [PDF]
, 1997 In the path integral expression for a Feynman propagator of a spinless particle of mass $m$, the path integral amplitude for a path of proper length ${\cal R}(x,x'| g_{\mu\nu})$ connecting events $x$ and $x'$ in a spacetime described by the metric tensor

Computational progress on the unfair 0-1 polynomial Conjecture [PDF]
arXiv, 2023 Let $c(x)$ be a monic integer polynomial with coefficients $0$ or $1$. Write $c(x) = a(x) b(x)$ where $a(x)$ and $b(x)$ are monic polynomials with non-negative real (not necessarily integer) coefficients. The unfair 0--1 polynomial conjecture states that $a(x)$ and $b(x)$ are necessarily integer polynomials with coefficients $0$ or $1$. Let $a(x)$ be a

Dynamics of Dimensions in Factor Space Cosmology [PDF]
, 1995 We consider multidimensional cosmological models with a generalized space-time manifold M = R x M_1 ...x M_n, composed from a finite number of factor spaces M_i, i=1,..n.

Heterozygosity for nuclear factor one x affects hippocampal-dependent behaviour in mice. [PDF]
PLoS ONE, 2013 Identification of the genes that regulate the development and subsequent functioning of the hippocampus is pivotal to understanding the role of this cortical structure in learning and memory.

An Infinite, Two-parameter Family of Polynomials with Factorization Similar to $X^m-1$ [PDF]
arXiv, 2021 For a suitable irreducible \textit{base} polynomial $f(x)\in \mathbf{Z}[x]$ of degree $k$, a family of polynomials $F_m(x)$ depending on $f(x)$ is constructed with the properties: (i) there is exactly one irreducible factor $\Phi_{d,f}(x)$ for $F_m(x)$ for each divisor $d$ of $m$; (ii) deg $(\Phi_{d,f}(x))=\varphi(d)\cdot\mathrm{deg} (f ...

Beyond the X Factor: Relevance of Sex Hormones in NAFLD Pathophysiology
Cells, 2021 Non-alcoholic fatty liver disease (NAFLD) is a major health issue worldwide, being frequently associated with obesity, unbalanced dietary regimens, and reduced physical activity. Despite their greater adiposity and reduced physical activity, women show a

Quantum communication complexity of symmetric predicates [PDF]
, 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(
