Influence of manganese on deformation behavior of lightweight steel at different strain rate
Journal of Materials Research and Technology, 2020 Tensile deformation behavior of Fe–0.25C–3.5(10)Mn–5Al lightweight steel was studied in a large range of strain rate (0.001–1200 s−1) by using a universal material testing machine, intermediate strain rate tensile testing apparatus and rotation disk bar ...

DNA ligase LigE increases bacterial transformation with damaged extracellular DNA
FEBS Letters, EarlyView.The DNA ligase LigE from the naturally competent Gram‐negative bacterium Neisseria gonorrhoaea increases transformation with cut extracellular DNA. This process is ATP‐dependent and relies on the catalytic activity of LigE; it also requires that LigE contains an intact periplasmic localisation sequence, indicating that ligE functions in the periplasm ...

Molecular Oncology, EarlyView.This study shows that lung adenocarcinomas exploit developmental branching morphogenesis to acquire a therapy resistant basal‐like tumour cell state. This process was found to be regulated by combined TP53 loss‐of‐function and type‐I interferon signalling, identifying a novel axis for biomarker and therapeutic target discovery.

Molecular Oncology, EarlyView.Matched spatial transcriptomics and single‐nuclei RNA‐seq were generated for anaplastic and BRAFV600E papillary thyroid cancers revealing generic and tumor‐specific states occurring in cancer cells and in the tumor microenvironment. In this context, cancer dedifferentiation mirrored organoid maturation through ordered thyroid marker gain/loss ...

Intermediate Strain-Rate Loading - Techniques and Applications [PDF]
, 1999 A new test methodology is described which allows access to loading rates that lie between split Hopkinson bar and shock-loading techniques. Gas gun experiments combined with velocity interferometry techniques have been used to experimentally determine ...

Targeting the EpCAM‐AXL axis to overcome drug resistance in lung cancer
Molecular Oncology, EarlyView.Lung cancer cells often evade therapy by hijacking signaling pathways. We reveal that cleaved EpCAM (sEpCAM) stabilizes the oncogenic protein AXL, driving NF‐κB and STAT3‐mediated chemoresistance. This EpCAM‐AXL axis identifies a high‐risk patient subset with poor prognosis.

Direct Tension Bar for Testing at Intermediate Strain Rate
, 2019 Dynamic material characterization at intermediate strain rates (10 - 100 s/1) is one of the major concerns in crash engineering. Servo-hydraulic machines and drop weight towers are regarded as the solution for measurement of mechanical properties at these strain rates.
