In accordance with some embodiments of the disclosed subject matter, mechanisms (which can, for example, include systems, methods, and media) for directional coordinated reset deep brain stimulation are provided. In some embodiments, a method is provided, comprising: implanting a lead with segmented electrodes into an anatomical structure; selecting a first subset of the electrodes corresponding to the anatomical structure as active electrodes; causing electrical pulses at a first stimulation level to be applied at the active electrodes in a first sequence; causing electrical pulses at a second stimulation level that is lower than the first stimulation level to be applied at the active electrodes in a second sequence during a second time period; and inhibiting electrical pulses from being applied at inactive electrodes during the second time period.

Systems, methods and media for directional coordinated reset deep brain stimulation

A system and method for characterizing a totality of particles selects a class of the totality of particles having a defined mobility; determines the total particle concentration of the class of particles; filters the class of particles using the filter apparatus and determines a filtered particle concentration indicative of the particles of the class which penetrate the filter apparatus; and determines at least one morphological parameter based on the fraction of particles of a class penetrating the filter apparatus.

Measurement of particle morphology using filtration

A method is proposed for characterizing a totality of particles. The method can be used in particular for characterizing microparticular or nanoparticular aerosols. The method comprises the following steps:

Measurement system for the multidimensional aerosol characterization

Multifocal optical device designs receive input parameters to specify a desired power distribution function, a power deviation weight function, and an astigmatism weight function over the design field. A fourth-order partial differential variational equation is linearized by defining the optical surface in terms of perturbations from a base surface such as a sphere or a toric. The solution may be expressed as piecewise quadratic splines superposed over a triangulation of the field. Evaluation of the surface may use a set of tensor-product splines. An astigmatic base surface permits both multiple magnifying powers and a prescribed astigmatism correction in a single optical surface.
