Long hold times in a two-junction electron trap [PDF]

, 2011
The hold time $\tau$ of a single-electron trap is shown to increase significantly due to suppression of environmentally assisted tunneling events. Using two rf-tight radiation shields instead of a single one, we demonstrate increase of $\tau$ by a factor

Infection Control Practices for Vascular Access Management in Hemodialysis: Results From a Nationwide Survey of Japanese National University Hospitals

Therapeutic Apheresis and Dialysis, EarlyView.
ABSTRACT Introduction Bloodstream infections due to repeated vascular access (VA) puncture and circuit connections remain major concerns in hemodialysis. Therefore, we examined current practices for glove, disinfectant, and personal protective equipment (PPE) use according to VA type in national university hospitals in Japan.

Structural biology of ferritin nanocages

FEBS Letters, EarlyView.
Ferritin is a conserved iron‐storage protein that sequesters iron as a ferric mineral core within a nanocage, protecting cells from oxidative damage and maintaining iron homeostasis. This review discusses ferritin biology, structure, and function, and highlights recent cryo‐EM studies revealing mechanisms of ferritinophagy, cellular iron uptake, and ...

Gamma ray exposure buildup factor and shielding features for some binary alloys using MCNP-5 simulation code

Nuclear Engineering and Technology, 2021
Gamma radiation shielding features for three series of binary alloys identified as (Pb–Sn), (Pb–Zn), and (Zn–Sn) have been investigated. The mass attenuation coefficients (μ/ρ) for the selected alloys were simulated using the MCNP-5 code in the energy ...

Factors affecting the computation of the ¹³C shielding in disaccharides [PDF]

Journal of Computational Chemistry, 2014
Knowledge of the three‐dimensional structures of glycans and glycoproteins is useful for a full understanding of molecular processes in which glycans are involved, such as antigen‐recognition and virus infection, to name a few. Among the ubiquitous nuclei in glycan molecules, the 13C nucleus is an attractive candidate for computation of theoretical ...
