The Fixed Point Property for Posets of Small Width
, 1998 The fixed point property for finite posets of width 3 and 4 is studied in terms of forbidden retracts. The ranked forbidden retracts for width 3 and 4 are determined explicitly.

Protein pyrophosphorylation by inositol pyrophosphates — detection, function, and regulation
FEBS Letters, EarlyView.Protein pyrophosphorylation is an unusual signaling mechanism that was discovered two decades ago. It can be driven by inositol pyrophosphate messengers and influences various cellular processes. Herein, we summarize the research progress and challenges of this field, covering pathways found to be regulated by this posttranslational modification as ...

Neocompact Sets and the Fixed Point Property
Journal of Mathematical Analysis and Applications, 2002 Dans cette Note l'auteur étudie des problèmes qui concernant la propriété de point fixe pour des applications nonexpansives; en particulier il donne une condition suffisante pour qu'un espace de Banach super-réflexif \(X\) ait la propriété de point fixe et il obtient des démonstrations intéressantes et plus coutes de résultats bien-connus de cette ...

The role of histone modifications in transcription regulation upon DNA damage
FEBS Letters, EarlyView.This review discusses the critical role of histone modifications in regulating gene expression during the DNA damage response (DDR). By modulating chromatin structure and recruiting repair factors, these post‐translational modifications fine‐tune transcriptional programmes to maintain genomic stability.

Fixed points of condensing multivalued maps in topological vector spaces
Fixed Point Theory and Applications, 2004 With the aid of the simplicial approximation property, we show that every admissible multivalued map from a compact convex subset of a complete metric linear space into itself has a fixed point.

On topological groups with an approximate fixed point property
Anais da Academia Brasileira de CiênciasA topological group G has the Approximate Fixed Point (AFP) property on a bounded convex subset C of a locally convex space if every continuous affine action of G on C admits a net ( x i ), x i ∈ C, such that x i - g x i ⟶ 0 for ...

Existence ofixed points for pointwise eventually asymptotically nonexpansive mappings
Applied General Topology, 2019 Kirk introduced the notion of pointwise eventually asymptotically non-expansive mappings and proved that uniformly convex Banach spaces have the fixed point property for pointwise eventually asymptotically non expansive maps.

FEBS Letters, EarlyView.Multidrug transporters BpeB and BpeF from the Gram‐negative pathogen Burkholderia pseudomallei have a hydrophilic patch in their substrate‐binding pocket. Drug susceptibility tests and growth curve analyses using an Escherichia coli recombinant expression system revealed that the hydrophilic patches of BpeB and BpeF are involved in the substrate ...

Generalized Common Fixed Point Results via Greatest Lower Bound Property
Journal of Applied Mathematics, 2014 The aim of this paper is to unify the concept of greatest lower bound (g.l.b) property and establish some generalized common fixed results. We support our results by a nontrivial example.
