Abstract: A system includes a top printed circuit (PCB) including an array of contact pads, a bottom PCB including an array of contact pads, at least one interposer positioned between the top and bottom PCBs, including: an array of top connectors configured to contact the array of contact pads of the top PCB; an array of bottom connectors configured to contact the array of contact pads of the bottom PCB; and interconnections configured to electrically connect the top connectors and the bottom connectors, at least one spacer element positioned between the top PCB and the bottom PCB and configured to contribute to maintaining a specified distance between the top PCB and the bottom PCB; and at least one fastener of the top PCB and the bottom PCB. The system further includes fasteners configured to press the top PCB, the interposer, the bottom PCB, and the spacer layer together.

Abstract: A baseboard includes a first connection configured to electrically interface with a motherboard, a second connection configured to electrically interface with a module, and a switch circuit configured to route data channels and power channels between the motherboard and the module. The first connection is configured to interface with more than one connection protocol or standard. The second connection is configured to interface with the more than one connection protocol or standard. The baseboard allows for cableless connections to allow unobstructed airflow over the components.

Abstract: The present invention is directed to crosslinked cation exchange polymers comprising a fluoro group and an acid group, pharmaceutical compositions of these polymers, compositions of a linear polyol and a salt of such polymer. Crosslinked cation exchange polymers having beneficial physical properties, including combinations of particle size, particle shape, particle size distribution, viscosity, yield stress, compressibility, surface morphology, and/or swelling ratio are also described. These polymers and compositions are useful to bind potassium in the gastrointestinal tract.

Abstract: Methods and apparatus for monitoring a network and generating overall health scores for communications nodes in the network are described. A monitoring system receives information from a variety of system elements and/or devices which provide information relating to communications service. The information received by the network monitoring system includes information indicating the number of outstanding work orders issued in regard to a trouble report, signal power level variance information, signal alarm information, uncorrectable error information, correctable error information, offline device information, etc. A set of scores for a node are generated based on the different types of received information. The scores are combined using a weighted sum to generate an overall node health score. Nodes are ranked based on overall node health scores and maintenance personal can view the scores as well as the underlying information corresponding to a node to facilitate identification of possible faults.

Abstract: A method of purification of non-enveloped or pseudo-enveloped virus produced in vitro uses a composition with at least one detergent. A method of purification can use multiple detergents, and a method of determining the presence and/or level of a non-enveloped or pseudo-enveloped virus in a sample includes treating with at least one detergent.

Abstract: Polybrene as an additive in cell culture medium is used in methods for the generation of high-titer hepatitis E virus stocks and assays for titration of hepatitis E virus. A cell culture medium containing polybrene is used for high-titer HEV generation, a method for determining the presence and/or the level of HEV in a sample, and an HEV titration assay using polybrene.
