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 ...

On the existence of fixed points that belong to the zero set of a certain function

, 2015
Let T : X - > X be a given operator and F-T be the set of its fixed points. For a certain function phi : X - > [0,infinity), we say that F-T is phi-admissible if F-T is nonempty and F-T subset of Z(phi), where Z(phi) is the zero set of phi.

Length modeling of the end cable harnesses between mechanical fixed points and electrical fixed points

工程科学与技术, 2016
:The cable harness branches assembled in aircrafts can be separated by fix points into a number of cable harnesses between the adjacent fix points. One kind of these cable harnesses between the adjacent fix points, which has the assembly feature: one fix

Common fixed points of set-valued mappings

International Journal of Mathematics and Mathematical Sciences, 2001
The main purpose of this paper is to obtain a common fixed point for a pair of set-valued mappings of Greguš type condition. Our theorem extend Diviccaro et al. (1987), Guay et al. (1982), and Negoescu (1989).

Decoding the dynamic extracellular matrix in cancer—3D models and bioscaffolds rewire the rules of tumor progression

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.

Convergence of approximating fixed points sets for multivalued nonexpansive mappings [PDF]

, 1991
summary:Let $K$ be a closed convex subset of a Hilbert space $H$ and $T:K \multimap K$ a nonexpansive multivalued map with a unique fixed point $z$ such that $\{z\}=T(z)$.
