In situ local shock speed and transit shock speed [PDF]
Annales Geophysicae, 1998 Abstract. A useful index for estimating the transit speeds was derived by analyzing interplanetary shock observations. This index is the ratio of the in situ local shock speed and the transit speed; it is 0.6–0.9 for most observed shocks. The local shock speed and the transit speed calculated for the results of the magnetohydrodynamic simulation show ...

Is your graduate nurse suffering from transition shock?
Journal of Perioperative Nursing, 2018 The term ‘transition shock’ is a relatively new concept used to describe the experience of moving from the comfortable and familiar role of the preregistration nursing student to the professional registered nurse (RN).

The Shocking Variability Of Exoplanet Transits [PDF]
Proceedings of the International Astronomical Union, 2013 AbstractAsymmetries in exoplanet transits are proving to be a useful tool for furthering our understanding of magnetic activity on both stars and planets outside our Solar System. Near-UV observations of the WASP- 12 system have revealed asymmetries in the timing of the transit when compared with the optical light curve.

A strategy to introduce multi-gradient structures into iron by explosive shock wave processing
Journal of Materials Research and Technology, 2023 A strategy combining shock-induced phase transition, twins, and dislocations to produce a multi-gradient structure in Fe is designed and proposed by the explosive processing method. A specific emulsion explosive is designed to introduce gradient pressure

Magnetostructural Transition Kinetics in Shocked Iron
Physical Review Letters, 2016 A generalized Heisenberg model is implemented to study the effect of thermal magnetic disorder on kinetics of the Fe α-ε transition. The barrier to bulk martensitic displacement remains large in α-Fe shocked well past the phase line but is much reduced in the [001] α-ε boundary.

OBLIQUE SHOCK WAVE REFLECTION FROM THE WALL [PDF]
Научно-технический вестник информационных технологий, механики и оптики, 2015 Regular and Mach (irregular) reflection of an oblique shock wave from the wall is considered. Criteria for the transition from regular to irregular reflection are described: von Neumann criterion and the criterion for fixed Mach configuration. Specific

Radiation-Mediated Shocks: Kinetic Processes and Transition to Collisionless Shocks [PDF]
Astronomy Reports, 2018 We analyze the main features of radiation-mediated shocks at arbitrary shock velocities, both non-relativistic and relativistic. We describe two mechanisms, which may lead to formation of a sharp viscous subshock within otherwise smooth velocity profile at the shock front, even if the radiation pressure in the upstream is overwhelmingly large.

FEBS Letters, EarlyView.Proteostasis and the gut microbiota play a key role in shaping host physiology. Microbiota‐derived metabolites, vitamins, and RNA modulate host proteostasis. Findings from model systems, including C. elegans, indicate microbes can either stabilize or disrupt host proteostasis.

Structural insights and therapeutic targets in Acinetobacter baumannii capsule biosynthesis
FEBS Letters, EarlyView.Hypervirulent KL49 A. baumannii's capsular polysaccharide contains the nonulosonic acid 8‐epi‐Leg5,7Ac2, synthesized by epimerization via ElaA, ElaB, and ElaC. Crystal structures of ElaA, ElaB, and ElaC reveal their role in CMP‐Leg5,7Ac2 synthesis and regioselective C8 epimerization.
