Factorization in weak products of complete Pick spaces [PDF]
, 2018 Let $\mathcal H$ be a reproducing kernel Hilbert space with a normalized complete Nevanlinna-Pick (CNP) kernel. We prove that if $(f_n)$ is a sequence of functions in $\mathcal H$ with $\sum\|f_n\|^2<\infty$, then there exists a contractive column multiplier $(\varphi_n)$ of $\mathcal H$ and a cyclic vector $F\in \mathcal H$ so that $\varphi_ n F=f_n ...

FEBS Letters, EarlyView.Low‐density lipoprotein receptor‐related protein 6 (LRP6) is a key receptor for the Wnt antagonist Dickkopf1 (DKK1). DKK1 protein expression is induced in a bleomycin (BLM)‐induced lung injury model. We show that DKK1 induces proinflammatory and profibrotic genes in lung fibroblasts.

Compliments of Factor H: What’s in it for AMD? [PDF]
Immunity, 2017 Genetic variations in complement factor H (CFH) confer greater risk for age-related macular degeneration (AMD). In this issue of Immunity, Calippe et al. (2017) uncover a non-canonical role for CFH in the inhibition of mononuclear phagocyte elimination from sub-retinal lesions, providing insight into the pathophysiology of AMD associated with CFH ...

Characteristics of the Kelch domain containing (KLHDC) subfamily and relationships with diseases
FEBS Letters, EarlyView.The Kelch protein superfamily includes 63 members, with the KLHDC subfamily having 10 proteins. While their functions are not fully understood, recent advances in KLHDC2's structure and role in protein degradation have highlighted its potential for drug development, especially in PROTAC therapies.

Factorization of cyclotomic polynomial values at Mersenne primes [PDF]
arXiv, 2021 We get some results about the factorization of $\phi_p(M) \in {\mathbb{F}}_2[x]$, where $p$ is a prime number, $\phi_p$ is the corresponding cyclotomic polynomial and $M$ is a Mersenne prime (polynomial). By the way, we better understand the factorization of the sum of the divisors of $M^{2h}$, for a positive integer $h$.

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 ...

The H-Factor of Anthropology [PDF]
L'Homme, 2019 « How can we make any progress in the understanding of cultures, ancient or modern, if we persist in dividing what the people join, and in joining what they keep apart ? »Arthur M. Hocart (1970 [1952] : 23). The recent exposure of hospitality in the public forum in relation to the 2015 refugee crisis has forced anthropology to return to hospitality ...

Insertion of the FeB cofactor in cNORs lacking metal inserting chaperones
FEBS Letters, EarlyView.Nitric oxide reductase is an enzyme found in the bacterial denitrification pathway. The NOR active site contains a non‐heme iron, often, but not always inserted with the assistance of chaperones. Here, we study the insertion of FeB in the subfamily of cNORs lacking chaperones and found a putative channel, conserved in the family, perhaps enabling the ...

On the free energy density of factor models on biregular graphs [PDF]
arXiv, 2020 Let $h(0),h(1),\dots,h(k)$ be a symmetric concave sequence. For a $(d,k)$-biregular factor graph $G$ and $x\in \{0,1\}^V$, we define the Hamiltonian \[H_G(x)=\sum_{f\in F} h\left(\sum_{v\in \partial f} x_v\right),\] where $V$ is the set of variable nodes, $F$ is the set of factor nodes.

Factorizations of Hopf quasigroups [PDF]
arXiv, 2022 In this paper we introduce the notion of factorization in the Hopf quasigroup setting and we prove that, if $A$ and $H$ are Hopf quasigroups such that their antipodes are isomorphisms, a Hopf quasigroup $X$ admits a factorization as $X=AH$ iff $X$ is isomorphic to a double cross product $A\bowtie H$ as Hopf quasigroups.
