    Abstract: Apparatus and methods are provided for treating diseases that produce elevated intraocular pressures, such as glaucoma, wherein the device includes a housing shell defining a cavity between a first end and a second end of the housing shell, and an elastic membrane disposed within the cavity to divide the cavity into a fluidic channel that permits a flow of fluid from the first end to the second end and a sealed cavity. The elastic membrane deforms to change the volume of the sealed cavity responsive to pressure fluctuations between the first and second ends, thereby varying the fluidic resistance of the flow of fluid through the fluidic channel.

    Abstract: Methods, systems, and apparatus, including computer programs encoded on a computer storage medium, for dimensionality reduction of time-series using contrastive learning. A method can include receiving multidimensional input time series data that includes data from a session or sessions that span time, selecting positive samples and negative samples from the multidimensional input time series data for respective reference samples from the multidimensional input time series data, wherein the positive samples and negative samples are each selected with a respective predetermined distribution across the time of the session or sessions of the multidimensional input time series, and mapping the reference samples, the positive samples, and negative samples into a common embedding space.

    Abstract: Electronic metadevice comprising a conductive channel; a metal layer superposed on the conductive channel; and a barrier layer located between the metal layer and the conductive channel. The metal layer includes at least one recess extending through the metal layer to define at least one metallic metastructure comprising at least one first metal layer portion adjacent to at least one second metal layer portion. The recess extends through the metal layer to define a micro-structured or a nano-structured first metal layer portion comprising at least one first metallic extension or finger extending away from a first support of the first metal layer portion towards the second metal layer portion; and a micro-structured or a nano-structured at least one second metal layer portion comprising at least one second metallic extension or finger extending away from a second support of the second metal layer portion towards the first metal layer portion.

    Abstract: ESP particle collector (1) for collecting particles in a particle containing gas stream, comprising an inlet section (4), a collector section (6), and an electrode arrangement (8), the inlet section comprising a flow tube (10) defining a gas flow channel (12) therein bounded by a guide wall (24) extending between an entry end (14) and a collector end (16) that serves as an inlet to the collector section (6), the entry end comprising an inlet (28) for the particle gas stream and a sheath flow inlet portion (26) for generating a sheath flow around the particle gas stream, the collector section comprising a housing (18) coupled to the flow tube, and a collector plate (20) mounted therein having a particle collection surface (23). The ESP particle collector is configured to allow optical analysis of the collector plate particle collection surface to measure particles collected thereon. The electrode arrangement comprises at least a base electrode (8a) positioned below the collection surface and a counter-base electrode (8b) positioned at a separation distance L2 above the collection surface such that an electrical field is generated between the electrodes configured to precipitate said particles on the collection surface, wherein the electric field is in a range of 0.1 kV per mm to 1.5 kV per mm, with an absolute voltage on any said electrode that is less than 10 kV, and wherein a ratio ratio I of a radius LI of said inlet at the collector end divided by said separation distance L2 is in a range of 0.8 to 1.2.
