Intrinsic Optical Imaging of Cortex During Deep Brain Stimulation: Parameters, Spatiotemporal Dynamics and Neurovascular Coupling
Deep brain stimulation (DBS) is clinically used to treat various movement disorders and has a potential to ameliorate other conditions such as depression, epilepsy etc. However, the mechanism through which DBS alleviates symptoms is not clear which prevents its efficient application and expansion …

Does Cable Television Face a Nationwide Competitor in Direct Broadcast Satellite Service?
… competitor exists, Direct Broadcast Satellite ("DBS"), and there are some indications that DBS does not constrain cable prices. The model presented in this paper indicates that DBS and cable compete imperfectly in terms of monthly prices, if at all, but compete more directly in terms of the …

Direct analysis of dried blood spot samples
… was to identify and develop a dried blood spot (DBS) direct analysis technique that could support high sample throughput quantitative bioanalysis in a regulated drug development environment. An initial literature review, coupled with proof of concept testing of the most prominent direct analysis …

Quantifying the pathways modulated by deep brain stimulation for essential tremor using computational modeling
Deep brain stimulation (DBS) within or near the ventral intermediate nucleus of thalamus (Vim) is known to exert a therapeutic effect on postural and kinetic tremor in patients with Essential Tremor (ET). For patients with DBS leads placed near the caudal border of Vim, however, there is an …
