Crack Identification in Cantilever Beam under Moving Load Using Change in Curvature Shapes
Computation, 2022 Cracks in structural components may ultimately lead to failure of the structure if not identified sufficiently early. This paper presents a crack-identification method based on time-domain.

Epigenetic reprogramming of lineage switching in cancer
FEBS Letters, EarlyView.Cancer cells rarely commit to a single identity. Epigenetic mechanisms and tumor microenvironment cues push epithelial cells toward flexible, hybrid states that can shift into mesenchymal, neuroendocrine, or stem‐like fates, driving metastasis, drug resistance, and tumor heterogeneity. Targeting the epigenetic regulators behind these transitions, using

Dynamics of a two-layer half-space with initial stresses under the impact of a moving load
Науковий вісник Ужгородського університету. Серія: Математика і інформатика, 2022 In this article, within the framework of the linearized theory of elasticity for bodies with initial stresses, we consider a plane steady-state problem of perturbation of a two-layer half-space with an arbitrary form of elastic potential by a surface ...

Synergistic perspectives—How single‐molecule biophysics complement biochemical understanding
FEBS Letters, EarlyView.In this review, we discuss how ensemble biochemistry and single‐molecule approaches are complementary, outline commonly used single‐molecule techniques, and illustrate their relevance through two representative case studies: chromatin organization by SMC complexes and pathway choice during DNA double‐strand break repair.

FEBS Letters, EarlyView.Mycobacterial 3‐methylcrotonyl‐CoA carboxylase uses a mobile biotin‐carrying domain to shuttle a carboxyl group between two catalytic sites, enabling carboxylation of 3‐methylcrotonyl‐CoA during leucine breakdown. Cryo‐electron microscopy captures the carrier at both sites and reveals an inward loop movement that may prevent futile rebinding to the ...

Modeling of Flexible Multibody Systems Excited by Moving Loads with Application to a Robotic Portal System [PDF]
, 2012 In this paper, an approach to solve mechanical problems with moving loads and flexible bodies is presented. Therefore, the multi-disciplinary modeling language Modelica together with the DLR FlexibleBodies Library is utilized.

FEBS Letters, EarlyView.How do genomes gain new functional parts? In eukaryotes, which tend to evolve under weak selection, much of the genome is junk. Palazzo and Qiu borrow the logic of Markov chains to show how non‐functional DNA becomes functional through the appearance of intermediate states, which arise due to epistasis, buffering, and biochemical messiness, allowing ...
