We studied the influence of a static in-plane magnetic field on alternating-field-driven emission nanoscale spin waves from vortex cores. Time-resolved scanning transmission X-ray microscopy was used to image in disk structures synthetic ferrimagnets and single ferromagnetic layers. For both systems, it found that an increasing bias continuously displaces wave-emitting core center toward its ed...

The conformation and drift properties of a telechelic chain moving through a porous host of randomly distributed static obstacles are studied using Brownian dynamics simulation for a Grest–Kremer bead-spring model of polymer. Static chain conformations exhibit non-monotonic behaviour as a function of the impurity density ρimp at zero bias. The chain initially shrinks due to an entropic barrier ...

We measure the temperature, magnetic-field, and current dependence for the switching of nanomagnets by a spin-polarized current. Depending on current bias, switching can occur between either two static magnetic states or a static state and a current-driven precessional mode. In both cases, the switching is thermally activated and governed by the sample temperature, not a higher effective magnet...

BACKGROUND AND OBJECTIVES Attention Bias Modification (ABM) targets attention bias (AB) towards threat and is a potential therapeutic intervention for anxiety. The current study investigated whether initial AB (towards or away from spider images) influenced the effectiveness of ABM in spider fear. METHODS AB was assessed with an attentional probe task consisting of spider and neutral images p...

The most promising scheme for high-speed low power communication over long on-chip interconnects is Current-mode signaling (CMS) with dynamic overdriving scheme. A variation tolerant dynamic overdriving CMS scheme is proposed. The proposed CMS scheme employs a smart bias circuit in transmitter side. The smart bias is energy efficient and it reduces the delay. Current-mode signaling (CMS) scheme...
