Ultradiscrete kinks with supersonic speed in a layered crystal with realistic potentials [PDF]
, 2015 We develop a dynamical model of the propagating nonlinear localized excitations, supersonic kinks, in the cation layer in a silicate mica crystal. We start from purely electrostatic Coulomb interaction and add the Ziegler-Biersack-Littmark short-range ...

Estimation Method and Verification of Pressure in Supersonic Inlet
Hangkong gongcheng jinzhan, 2020 Prediction and limitation of inlet pressure are important for supersonic vehicles. Numerical simulation on high speed inlet flow is conducted, and pressure characteristics with different Mach numbers, attack angles, yaw angles and excess air coefficients

Conditions for one-dimensional supersonic flow of quantum gases
, 2004 One can use transsonic Bose-Einstein condensates of alkali atoms to establish the laboratory analog of the event horizon and to measure the acoustic version of Hawking radiation. We determine the conditions for supersonic flow and the Hawking temperature

Effect of Quasi-Static Door Operation on Shear Layer Bifurcations in Supersonic Cavities
AerospaceSpan-wise homogeneous supersonic cavity flows display complicated structures due to shear layer breakdown, flow acoustic resonance, and even non-linear hydrodynamic-acoustic interactions. In practical applications, such as aircraft bays, the cavity is of

Can Protostellar Jets Drive Supersonic Turbulence in Molecular Clouds?
, 2007 Jets and outflows from young stellar objects are proposed candidates to drive supersonic turbulence in molecular clouds. Here, we present the results from multi-dimensional jet simulations where we investigate in detail the energy and momentum deposition

Economic benefits of supersonic overland operation [PDF]
, 1992 Environmental concerns are likely to impose some restrictions on the next generation of supersonic commercial transport. There is a global concern over the effects of engine emissions on the ozone layer which protects life on Earth from ultraviolet ...

Pediatric Blood &Cancer, EarlyView.ABSTRACT Primary lung carcinomas and bronchial carcinoid tumors (BC) are very rare malignancies in childhood. While typical BC and mucoepidermoid carcinomas are mostly low‐grade, localized tumors with a more favorable prognosis than in adults, necessitating avoidance of overtreatment, adenocarcinomas of the lung are often diagnosed at advanced disease ...
