Fast‐scanning small‐angle X‐ray scattering of hydrated biological cells

Journal of Synchrotron Radiation, EarlyView.
Fast‐scanning small‐angle X‐ray scattering on biological cells in aqueous environments reveals intracellular anisotropy and orientation, and allows for systematic assessment of radiation damage caused by the measurements.Due to their high penetration depth, X‐rays enable us to obtain information from the interior of whole unsliced cells. Scanning small‐

Things at Work: How Things Contribute to Performing Work

Journal of Management Studies, EarlyView.
Abstract A crucial question for organizations is what constitutes work performance. While the importance of human competence and motivation to work performance has been established, less well understood is how ‘things’ – such as algorithms, tools, instruments, and raw materials – contribute to work performance.

Computational Simulation of Shock-Bubble Interaction, using a Front-Tracking/Ghost Fluid Method

Journal of Applied Fluid Mechanics, 2019
A front tracking/ghost fluid method was used to simulate fluid interfaces in a shock–bubble interaction problem. The method captures fluid interfaces, using explicit front-tracking and defines interface conditions, using the ghost-fluid method.

A reduced cluster dynamics modeling of radiation damage in tungsten

Nuclear Materials and Energy
A reduced cluster dynamics model is developed to investigate the microstructure evolution of irradiated single crystal tungsten. The model accounts for the generation and reaction of point defects, small-size defect clusters, helium clusters, as well as ...

Electron Bubbles in Liquid Helium

, 2003
When an electron (or positronium atom) is injected into liquid helium with nearly zero energy, a bubble quickly forms around it. This phenomenon (which also occurs in liquid hydrogen, liquid neon and possibly in solid helium) lowers the mobility of the electron to a value similar to that for a positive ion.

Multi‐Omics Analyses Reveal the Red and Far‐Red Light Combination Enhancing Heterologous Protein and Metabolite Production in Nicotiana benthamiana

Plant, Cell &Environment, EarlyView.
ABSTRACT Transient expression of exogenous protein in Nicotiana benthamiana leaves via agroinfiltration offers a rapid and efficient platform for functional gene discovery and heterologous production of valuable eukaryotic proteins and metabolites. Though light quality is an important factor for plant photomorphogenesis, its impact on the efficiency of

Spaceborne and spaceborn: Physiological aspects of pregnancy and birth during interplanetary flight

Experimental Physiology, EarlyView.
Abstract Crewed interplanetary return missions that are on the planning horizon will take years, more than enough time for initiation and completion of a pregnancy. Pregnancy is viewed as a sequence of processes – fertilization, blastocyst formation, implantation, gastrulation, placentation, organogenesis, gross morphogenesis, birth and neonatal ...
