ABSTRACT We examine the migration of luminous low-mass cores in laminar protoplanetary discs where accretion occurs mainly because disc winds and planet luminosity is generated by pebble accretion. Using 2D hydrodynamical simulations, we determine eccentricities induced thermal forces as a function gas rates, also evaluate importance torque exerted solid component relative to torque. For rate $...

Physiological studies of the lateral geniculate nucleus (LGN) have revealed three classes of relay neurons, called X, Y, and W cells in carnivores and parvocellular (P), magnocellular (M), and koniocellular (K) in primates. The homological relationships among these cell classes and how receptive field (RF) properties of these cells compare with LGN cells in other mammals are poorly understood. ...

Aims. We investigate the response of an accretion disk to the presence of a perturbing protoplanet embedded in the disk through time dependent hydrodynamical simulations. Methods. The disk is treated as a two-dimensional viscous fluid and the planet is kept on a fixed orbit. We run a set of simulations varying the planet mass, and the viscosity and temperature of the disk. All runs are followed...

Using the spatial cueing technique, this study demonstrates that the center of mass (centroid) of a visual scene has a special ability to attract attention even when there is no object presented at this location. Four boxes formed an imaginary square and were presented to the left or right hemifield. After the cueing in one box, a target appeared in one of the four boxes and, in addition, at ce...

We consider modulations of mass captured by the compact object from the companion star’s stellar wind in Low Mass X-ray Binaries with late type giants. Based on 3D simulations with two different hydrodynamic codes used Lagrangian and Eulerian approaches – the SPH code GADGET and the Eulerian code PLUTO, we conclude that a hydrodynamical interaction of the wind matter within a binary system even...

The paper presents a mathematical base modeling combined to Modified-Winding -Function-Approach (MWFA) for eccentricity fault detection of a round-rotor synchronous machine. For this aim, a 6-pole machine is considered, and the machine inductances are computed by MWFA in healthy and also under eccentricity fault. A numerical discrete-time method has been proposed to machine modeling in voltage-...

Abstract Upon entering the tidal sphere of a supermassive black hole, star is ripped apart by tides and transformed into stream debris. The ultimate fate that debris, properties bright flare produced observed, depends on number parameters, including energy center mass original star. Here we present results set smoothed particle hydrodynamics simulations in which 1 M ⊙ , γ = 5/3 polytrope disrup...

the eccentricity connectivity index of a molecular graph g is defined as (g) = av(g)deg(a)ε(a), where ε(a) is defined as the length of a maximal path connecting a to othervertices of g and deg(a) is degree of vertex a. here, we compute this topological index forsome infinite classes of dendrimer graphs.

Abstract Inferring planetary parameters from transit timing variations (TTVs) is challenging for small exoplanets because their transits may be so weak that determination of individual difficult or impossible. We implement a useful combination tools together provide numerically fast global photodynamical model. This used to fit the TTV-bearing light curve, in order constrain masses transiting l...
