Normal Reflection and Transmission of Plane Shock Waves in Nonlinear Elastic Material

Engineering Transactions, 1986
The normal reflection (reflection and transmission) of a finite elastic plane shock wave at a plane boundary (plane interface of two rigidly coupled materials), propagating through an elastic Murnaghan's material is examined.

Ionospheric scintillation modeling. I. Validity of the plane wave approximation for an electromagnetic wave illuminating the ionosphere

Journal of Space Weather and Space Climate
Low Earth Orbit (LEO) satellites have a low altitude orbital track around the Earth. For a satellite to Earth link passing through the ionosphere, the approximation of the electromagnetic wave illuminating the ionosphere irregularities by a plane wave is

Killing tensors in pp-wave spacetimes

, 2010
The formal solution of the second order Killing tensor equations for the general pp-wave spacetime is given. The Killing tensor equations are integrated fully for some specific pp-wave spacetimes.

Colliding plane gravitational waves

Journal of Mathematical Physics, 1979
New exact solutions of the vacuum Einstein field equations are constructed which describe the collision of plane gravitational waves. These solutions generalize those of Szekeres by relaxing the requirement of collinear polarization.

Elevated Connectivity During Language Processing Is Associated With Cognitive Performance in SeLECTS

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective Self‐Limited Epilepsy with Centrotemporal Spikes (SeLECTS) is associated with language impairments despite seizures originating in the motor cortex, suggesting aberrant cross‐network interactions. Here we tested whether functional connectivity in SeLECTS during language tasks predicts language performance.

Black strings in asymptotically plane wave geometries

, 2003
We present a class of black string spacetimes which asymptote to maximally symmetric plane wave geometries. Our construction will rely on a solution generating technique, the null Melvin twist, which deforms an asymptotically flat black string spacetime ...

Clinical Outcomes of SEEG‐Guided Radiofrequency Thermocoagulation in Children With Focal Drug‐Resistant Epilepsy: A Multicenter Real‐World Study

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective Stereoelectroencephalography‐guided radiofrequency thermocoagulation (SEEG‐RFTC) has emerged as a safe and effective minimally invasive treatment for children with drug‐resistant focal epilepsy. Although evidence from real‐world studies remains limited, numerous pediatric cases have demonstrated promising outcomes. This retrospective

Twisted electron in a strong laser wave

, 2012
Electrons carrying orbital angular momentum (OAM) have recently been discovered theoretically and obtained experimentally that opens up possibilities for using them in high-energy physics. We consider such a twisted electron moving in external field of a
