Some new fixed point results for multi-valued weakly Picard operators

Filomat, 2019
In this paper, we present some extensions of Banach contraction principle for multi-valued maps. Corresponding convergence theorems for the Picard iteration associated to a class of multi-valued operators are obtained in the setting of modular metric spaces.

CHD4 Orchestrates Chromatin Remodeling to Activate the c‐Myc Signaling Pathway in Cancer Pathogenesis

MedComm – Oncology, Volume 5, Issue 2, June 2026.
CHD4 plays an essential role as an epigenetic regulator in the pathogenesis of multiple myeloma. The chromatin remodeling protein initially resolves G‐quadruplex (G4) secondary structures within the c‐Myc promoter region, thereby enhancing chromatin accessibility and promoting transcriptional activation.

Fixed Points of Integral Type Contractions in Uniform Spaces with a Graph [PDF]

, 2013
In this paper, we discuss the existence of fixed points for integral type contractions in uniform spaces endowed with both a graph and an $E$-distance. We also give two sufficient conditions under which the fixed point is unique.

Genetic Architecture of Addiction‐Relevant Behaviors in Outbred Sprague–Dawley Rats Reveals Loci for Anxiety‐Like and Nociceptive Traits

Genes, Brain and Behavior, Volume 25, Issue 3, June 2026.
Genome‐wide association analyses in outbred Sprague–Dawleys identified loci for anxiety‐like and nociceptive behavior on chromosomes 1, 14, and 17, which are distinct from facets of exploratory locomotion significant in our GWAS of a F2 intercross of selectively bred high‐ and low‐responder (to a novel environment) Sprague–Dawleys.

When Knowledge Is Power: Leveraging Green Innovation Through Employee Training

International Journal of Training and Development, Volume 30, Issue 2, Page 131-148, June 2026.
ABSTRACT This paper aims to examine the relationship between investments in employee training and green innovation outcomes in German firms. The study investigates how these training expenditures influence the development and implementation of innovations that lead to environmental benefits, such as reduced energy consumption or emissions.

Structure and sequence evolution in the pennycress (Thlaspi arvense) pangenome

New Phytologist, Volume 250, Issue 5, Page 2723-2741, June 2026.
Summary Eukaryotic genomes harbor many forms of variation, including nucleotide diversity and structural polymorphisms, which experience natural selection and contribute to genome evolution and biodiversity. Harnessing this variation for agriculture hinges on our ability to detect, quantify, catalog, and deploy genetic diversity. Here, we explore seven

ZSL Orchestrates Synaptonemal Complex Assembly as a Central Region Scaffold to Ensure Synapsis Fidelity and Crossover Control in Polyploid Meiosis

Advanced Science, Volume 13, Issue 27, 13 May 2026.
A central molecular adaptor, ZSL, is identified that links transverse filaments ZYP1 to central element SCEP1/2 to drive synaptonemal complex assembly in Brassica napus. Loss of ZSL abolishes synaptonemal complex formation, disrupts meiotic chromosome segregation, and markedly increases crossovers, providing mechanistic insight into meiotic fidelity ...

Ligand‐driven modulation of chaperone–cochaperone networks shapes proteostasis outcomes

Protein Science, Volume 35, Issue 5, May 2026.
Abstract Protein homeostasis depends on a delicate interplay between folding and degradation, orchestrated by molecular chaperones. Among them, Hsp90 is a central hub, regulating nearly 10% of the proteome through ATP‐driven conformational cycles and selective interactions with cochaperones.
