Oscillatory migration of accreting protoplanets driven by a 3D distortion of the gas flow
, 2019 Context. The dynamics of a low-mass protoplanet accreting solids is influenced by the heating torque, which was found to suppress inward migration in protoplanetary disks with constant opacities. Aims.

Robust BDCM Sensorless Control With Position-Dependent Load Torque [PDF]
2007 IEEE Power Electronics Specialists Conference, 2007 This paper presents the robust sensorless operation for brushless DC motors (BDCMs) loaded by the position- dependent load where the load torque is a function of the rotor angle (not electrical angle). Without any position sensor, the reliable position signals are generated from the motor terminal voltages through sensorless circuits.

Current-driven dynamics of chiral ferromagnetic domain walls [PDF]
, 2013 In most ferromagnets the magnetization rotates from one domain to the next with no preferred handedness. However, broken inversion symmetry can lift the chiral degeneracy, leading to topologically-rich spin textures such as spin-spirals and skyrmions via

FEBS Letters, EarlyView.Ascidian Ciona larvae initially show strong clockwise tail twisting, which is largely corrected during development. However, a small residual twist remains. This study shows that organized helical myofibrils in tail muscles mechanically stabilize this residual asymmetry, preventing complete restoration of bilateral symmetry and revealing how embryos ...

Type I migration in optically thick accretion discs
, 2012 We study the torque acting on a planet embedded in an optically thick accretion disc, using global two-dimensional hydrodynamic simulations. The temperature of an optically thick accretion disc is determined by the energy balance between the viscous ...

The steady oblique path of buoyancy-driven disks and spheres [PDF]
, 2012 We consider the steady motion of disks of various thicknesses in a weakly viscous flow, in the case where the angle of incidence $\alpha$ (defined as that between the disk axis and its velocity) is small.

FEBS Open Bio, EarlyView.ERα splice variant ERα∆7 lacks the C‐terminus, and its expression may change phenotypes of breast cancers. Our results showed that ERα∆7 is found in the luminal A subtype, and elevated ERα∆7 levels are linked to improved cell survival with lower proliferation and migration.
