Directed evolution of enzymes at the crossroads of tradition and innovation
FEBS Open Bio, EarlyView.An iterative cycle of data‐driven enzyme optimization comprising four stages: genetic diversification of a template enzyme, expression of protein variants, high‐throughput evaluation, and machine‐learning‐guided redesign of the next variant library.

Best proximity point theorems for generalized α-β-proximal quasi-contractive mappings
Fixed Point Theory and Applications, 2017 Herein, we search for some best proximity point results for a novel class of non-self-mappings T : A ⟶ B $T:A \longrightarrow B$ called generalized proximal α-β-quasi-contractive. We illustrate our work by an example.

Best proximity points revisited
Filomat, 2019 In this paper, using the concept of w-distance on a metric space, we prove some new best proximity point results for the mappings of Meir-Keeler type. As an application, we derive some recent best proximity point results of the aforementioned type.

Best Proximity Point Theorems for the Generalized Fuzzy Interpolative Proximal Contractions
, 2022 The idea of best proximity points of the fuzzy mappings in fuzzy metric space was intorduced by Vetro and Salimi. We introduce a new type of proximal contractive condition that ensures the existence of best proximity points of fuzzy mappings in the fuzzy

Transcripts enriched in codons that trigger P‐site tRNA‐mediated mRNA decay possess stable mRNA
FEBS Open Bio, EarlyView.PTMD codons were first described by Mendel et al. as mediators of an mRNA decay pathway dependent on the human protein CNOT3, homologous to yeast Not5. Our findings confirm that PTMD codons destabilize transcripts; however, unlike in yeast, the human pathway specifically targets and slightly destabilizes primarily stable mRNAs.

Best Proximity Pairs Theorems for Continuous Set-Valued Maps
, 2008 A best proximity pair for a set-valued map F:A⊸B with respect to a set-valued map G:A⊸A is defined, and a new existence theorem of best proximity pairs for continuous set-valued maps is proved in nonexpansive retract metric spaces.

Best Proximity Point for the Sum of Two Non-Self-Operators
Journal of Mathematics, 2020 In the present paper, we focus our attention on the existence of the fixed point for the sum of the cyclic contraction and the noncyclic accretive operator. Also, we study the best proximity point for the sum of two non-self-mappings.

FEBS Open Bio, EarlyView.The cytoskeleton‐mediated transport of mitochondria via tunnelling nanotubes restores respiration, increases ATP production, rescues cells from apoptosis, activates the AKT/mTOR signalling pathway, promotes cell migration and invasiveness, contributes to cancer progression and treatment resistance.

Coupled Best Proximity Point Theorem in Metric Spaces
International Journal of Analysis and Applications, 2013 The purpose of this article is to generalized the result of W. Sintunavarat and P. Kumam [29]. We also give an example in support of our theorem for which result of W. Sintunavarat and P. Kumam [29] is not true.

Weak PG-property and best proximity points
Publications de l'Institut Mathematique, 2018 Summary: Abkar and Gbeleh proved the existence of best proximity points for multivalued nonself mappings on a complete metric space. We generalize/extend their result by introducing the notion of weak \(P_G\)-property. We also construct some examples in the support of our results.
