We investigated how novel sensorimotor feedback loops can be formed in the course of learning. More specifically, we examined motor adaptation in an experiment which systematically paired a lateral force pulse at movement onset with a delayed visual target perturbation. Learning in this context means associating the cue and the perturbation, such that sensory feedback about the cue triggers a c...

We propose a novel method of controlling a multi-phase fluid so that it flows into a target shape in a natural way. To preserve the sharp detail of the target shape, we represent it as an implicit function and construct the level-set of that function. Previous approaches add the target-driven control force as an external term, which then becomes attenuated during the velocity projection step, m...

Seiring dengan perkembangan teknologi yang semakin meningkat, banyak ditemukan penemuan baru dapat mempermudah kehidupan manusia, salah satunya yaitu situs website. Banyaknya website di internet mengakibatkan tingkat keamanannya menurun. Hal tersebut menjadi rentan untuk diretas dan diambil alih orang tidak bertanggung jawab. Salah satu cara peretas menyerang adalah mencari direktori web memili...

This paper addresses the problem of controlling the density and dynamics of smoke so that the synthetic appearance of the smoke resembles a still or moving object. The target object is modeled as a volumetric density function. In order to match the target density with the smoke density, we propose an approach to design an imaginary force field including both long-range and short-range forces as...

Cardiac catheters allow physicians to access the inside of the heart and perform therapeutic interventions without stopping the heart or opening the chest. However, conventional manual and actuated cardiac catheters are currently unable to precisely track and manipulate the intracardiac tissue structures because of the fast tissue motion and potential for applying damaging forces. This paper ad...

An external force-assisted near-field illumination biosensor (EFA-NI biosensor) detects a target substance that is propelled through an evanescent field by an external force. The target substance is sandwiched between an antibody coupled to a magnetic bead and an antibody coupled to a polystyrene bead. The external force is supplied by a magnetic field. The magnetic bead propels the target subs...

Sensorimotor impairments are common in autism spectrum disorder (ASD), but they are not well understood. Here we examined force control during initial pulses and the subsequent rise, sustained, and relaxation phases of precision gripping in 34 individuals with ASD and 25 healthy control subjects. Participants pressed on opposing load cells with their thumb and index finger while receiving visua...

Pinning of spiral waves by defects in cardiac muscle may cause permanent tachycardia. We numerically study the removal of a pinned spiral by a localized stimulus at the boundary of a two-dimensional excitable medium. It is shown that target waves may be generated by an external local force, and then the target waves will interact with the pinned spiral. When the external force is appropriately ...

We extend our previous calculation of the breakup 11Be using Halo Effective Field Theory and Dynamical Eikonal Approximation to include an effective 10Be-n-target force. The force is constructed account for virtual excitation 10Be its low-lying 2+ excited state. In case on a 12C target this improves description neutron-energy angular spectra, especially in vicinity 52+ By fine-tuning range para...
