Binary fractions and mass ratio distribution indices of 61 open clusters
Astronomy & AstrophysicsContext. Open clusters (OCs) are crucial for studying stellar formation and evolution, while understanding binary stellar formation and star cluster dynamics is key to advancing the field of stellar astrophysics.

FEBS Letters, EarlyView.CT10 regulator of kinase (CRK) and CRK‐Like (CRKL) are signaling adaptors driving cell adhesion, motility, differentiation, and proliferation. SH2‐domain containing (SH) proteins are enriched in YXXP motifs which when phosphorylated create preferred binding sites for CRK family SH2 domains.

Reconstructing enzyme evolution by protein engineering
FEBS Letters, EarlyView.Natural enzyme evolution can be retraced by protein engineering methods such as directed evolution, rational design, and ancestral sequence reconstruction. These approaches reveal how enzymes emerged from ligand‐binding scaffolds, developed varying substrate preferences, formed oligomeric complexes, adapted to environmental changes, and evolved novel ...

Classical and relative realizability [PDF]
, 2016 We show that every abstract Krivine structure in the sense of Streicher can be obtained, up to equivalence of the resulting tripos, from a filtered opca (A,A') and a subobject of 1 in the relative realizability topos RT(A',A); the topos is always a ...

FEBS Letters, EarlyView.Cancer progression is regulated by the dynamic matrix code of the tumor microenvironment, which influences cellular behavior and disease development. Importantly, matrix remodeling in three‐dimensional cancer models more accurately reflects in vivo conditions compared to conventional two‐dimensional systems.

Heegaard Floer correction terms, with a twist [PDF]
, 2016 We use Heegaard Floer homology with twisted coefficients to define numerical invariants for arbitrary closed 3-manifolds equipped torsion spinc structures, generalising the correction terms (or d--invariants) defined by Ozsv\'ath and Szab\'o for integer ...

Positivity of the Green functions for higher order ordinary differential equations
Electronic Journal of Differential Equations, 2008 We consider the equation $$ sum_{k=0}^n a_k(t)x^{(n-k)}(t)=0,quad tgeq 0, $$ where $a_0(t)equiv 1$, $a_k(t)$ ($k=1, dots, n$) are real bounded functions. Assuming that all the roots of the polynomial $z^n+a_1(t)z^{n-1}+ dots +a_n(t)$ ($tgeq 0$

HereditasIntroduction The bicoid (bcd) gene in Drosophila has served as a paradigm for a morphogen in textbooks for decades. Discovered in 1986 as a mutation affecting anterior development in the embryo, its expression pattern as a protein gradient later ...
