In this paper, the authors have analyzed the quasi-static frictional sliding of a springblock slider system under the Rate-State Friction (RSF) formalism with three state variables. The study of 3-state RSF systems have not been carried out in the literature, the authors claim that this warrants the study of mechanical behavior of such systems. I feel that that this is not justifiable scientifi...

The mass spectrum of S and P-wave mesons containing a single heavy quark is computed in the quenched approximation, using NRQCD up to third order in the inverse heavy quark mass expansion. Previous results found the expansion to break down near the charm quark mass for the S-wave spin splitting. The present work considers variations such as anisotropic lattices, Landau link tadpole improvement,...

Away from surface and bottom boundary layers turbulent mixing is primarily driven by breaking internal waves. While internal wave energy is generated mostly in the form of large-scale waves (typically internal tides), it is the smallest-scale internal waves that break through shear or convective instabilities to produce turbulence. When waves are reasonably linear (as opposed to, for example, s...

Coral reefs represent an efficient natural mechanical coastal defense against ocean waves. The focus of this study is La Saline fringing coral reef, located in the microtidal West Réunion Island Indian Ocean, frequently exposed to Southern Ocean swell and cyclonic events. aim provide a better understanding reef's characteristics for several Pressure sensors were placed across reef measure water...

The propagation of tides from the coastal ocean into shaHow estuarine waters often produces characteristic nonlinearly induced asymmetries of velocity and water level in time series. Until recently (Aubrey and Speer, 1985) a sound physical understanding of related phenomena has been difficult to obtain as flow field daia are rare. Numerical studies usually model a single estuary only; the model...

A quasi-three-dimensional suspended sediment transport model was developed and generalized to include combined wave-current effects to study bottom sediment resuspension and transport in southern Lake Michigan. The results from a threedimensional circulation model and a wind wave model were used as input to the sediment transport model. Two effects of nonlinear wave-current interactions were co...

A bstract We initiate the study of gravitational wave (GW) signals from first-order phase transitions in supersymmetry-breaking hidden sectors. Such often occur along a pseudo-flat direction universally related to supersymmetry (SUSY) breaking sectors that spontaneously break R -symmetry. The potential this imbues transition with number novel properties, including nucleation temperature well be...

increasing development of nano-technology in optics and photonics by using modern methods of light control in waveguide devices and requiring miniaturization and electromagnetic devices such as antennas, transmission and storage as well as improvement in the electromagnetic tool, have led researchers to use the phenomenon of electromagnetically induced transparency (eit) and similar phenomena i...
