Postcollision-interaction (PCI) effects involving multistep decay processes following Ar $1s$ photoionization has been studied by Auger electron spectroscopy. The experiment focused on $LMM$ electrons measured in small photon energy steps across the threshold. Decay pathways that we include (1) ${\mathrm{Ar}}^{+*}2{p}^{--1}\ensuremath{\rightarrow}{\mathrm{Ar}}^{2+}3{p}^{--2}$ LMM\ensuremath{\al...

The Bitlis-Zagros Fold-Thrust Belt is one of the world?s largest deformation zones, extending from Eastern Mediterranean in southern Turkey to south Iran. This zone partitioned between different structures; however, little known about relative activities these structures and their effects on topography. An area located northern part Bitlis- Zagros Belt, just Anatolian Plateau was studied detail...

Soon after the discovery of the Kerr metric, Penrose realized that superradiance can be exploited to extract energy from black holes. The original idea (involving the breakup of a single particle) yields only modest energy gains. A variant of the Penrose process consists of particle collisions in the ergoregion. The collisional Penrose process has been explored recently in the context of dark m...

[1] The plate motion of India changed dramatically between 50 and 35 Ma, with the rate of convergence between India and Asia dropping from 15 to 4 cm/yr. This change is coincident with the onset of the India-Asia collision, and with a rearrangement of plate boundaries in the Indian Ocean. On the basis of a simple model for the forces exerted upon the edges of the plate and the tractions on the ...

Random billiards are billiard dynamical systems for which the reflection law giving the postcollision direction of a billiard particle as a function of the pre-collision direction is specified by a Markov (scattering) operator P . Billiards with microstructure are random billiards whose Markov operator is derived from a “microscopic surface structure” on the boundary of the billiard table. The ...

In this work, collisions between rotating atomic clusters composed of Lennard-Jones (LJ(n)) particles and an identical projectile have been investigated by means of trajectory simulations as a function of the cluster angular momentum J and internal energy E, and for different values of the projectile impact parameter b and relative velocity v(p). As expected, the collision (P(c)(b)) and capture...

A study is presented of a miniature ultrasonic surgical drill designed for bone biopsy, based on an ultrasonic/sonic drill which converts high frequency to low frequency vibrations through a freely vibrating mass between an ultrasonic transducer-horn and a drill bit. For conventional surgical drilling using a rotary drill or an ultrasonic drill, considerable power is required to penetrate into ...

South China is a well-known grand felsic igneous rocks province. However, it still controversial and not well understood whether the Mesozoic tectono-magmatic pattern dominated by subduction of paleo-Pacific oceanic plate. In this study, we address question concentrating on long-term evolutionary Guandimiao batholith, which has complex lithofacies with different formation ages can be superb rec...

By a random billiard we mean a billiard system in which the standard specular reflection rule is replaced with a Markov transition probabilities operator P that, at each collision of the billiard particle with the boundary of the billiard domain, gives the probability distribution of the postcollision velocity for a given pre-collision velocity. A random billiard with microstructure, or RBM for...
