In-situ characterization of radiation hardness of scintillating targets using heavy ion beams [PDF]

EPJ Web of Conferences
Scintillating materials are of interest for numerous applications related to ionizing radiation. Exposure to radiation induces damage in these materials, resulting in degradation of their scintillation properties.

Characterization of Impact Damage in Composites

, 1987
This paper will report on the results of a study of the application of advanced digital data acquisition technology to the problem of impact damage in composites. This area was chosen for the study because of the importance of developing better damage characterization methods and the limited scope of the damage itself.

Hyperosmotic stress induces PARP1‐mediated HPF1‐dependent mono(ADP‐ribosyl)ation

FEBS Letters, EarlyView.
Sorbitol‐induced hyperosmotic stress rapidly induces reversible mono(ADP‐ribosyl)ation (MARylation) on PARP1 without the signs of genotoxic signaling. We show that PARP1 autoMARylation is HPF1 dependent and forms hydroxylamine‐resistant O‐glycosidic linkages.

Characterization of Radiation Damage in Tungsten

, 2020
Tungsten as plasma-facing material of a future fusion reactor will be subjected to high-flux neutron irradiation. The defect creation and its influence on hydrogen retention in tungsten irradiated with different ions were investigated. The microstructure and hydrogen retention was studied with transmission electron microscopy, positron annihilation ...

An isoform of 14‐3‐3 protein regulates transbilayer lipid movement at the plasma membrane

FEBS Letters, EarlyView.
Loss of 14‐3‐3ζ in CHO cells confers resistance to exogenous phosphatidylserine (PS) and impairs endocytosis‐independent inward flip‐flop of fluorescent PS at the plasma membrane. RNAi‐mediated knockdown reproduces this defect, while no additive effect is seen in ATP11C‐deficient cells.

Determination of Damage Constant and Critical Damage by the Combined Experiment and FEM Using the Reference Processes

Metals
The practical characterization algorithm is presented to find the optimized damage constants and critical damages of the traditional damage models formulated by some unknown damage constants. The flow characterization of the material SWCH45F is conducted

Epigenetic blind spots – the role of DNA methylation dynamics in stem cell‐based models of embryogenesis

FEBS Letters, EarlyView.
Embryo‐like structures (stembryos) are an innovative tool, but they are hindered by experimental variability and limited developmental potential. DNA methylation is crucial for mammalian development, but its status in stembryo models is poorly characterized.

Flood impact assessment in urban settings with porous buildings – insights from a fine-scale hydraulic-economic model [PDF]

Proceedings of the International Association of Hydrological Sciences
Classical hydraulic approaches of urban floods consider buildings as obstructions to water flow, without considering the flow exchanges between streets and buildings.

pH‐mediated activation of the lysosomal arginine sensor SLC38A9

FEBS Letters, EarlyView.
Cells monitor nutrient levels via the lysosomal transporter SLC38A9 to activate the mechanistic target of rapamycin complex 1 (mTORC1). This study reveals that SLC38A9 function is regulated by pH. We identified histidine 544 as a critical pH sensor that undergoes conformational changes to control amino acid efflux from lysosomes; therefore, it ...

Damage Identification in Various Types of Composite Plates Using Guided Waves Excited by a Piezoelectric Transducer and Measured by a Laser Vibrometer

Sensors, 2019
Composite materials are widely used in the industry, and the interest of this material is growing rapidly, due to its light weight, strength and various other desired mechanical properties. However, composite materials are prone to production defects and
