Abstract: A method of forming an polymer composites is disclosed herein that includes infiltrating CNT sponges with a polymer or metal to form a composite. The method uses a relatively easy, scalable, and low-cost synthesis process that makes the composites attractive as TIM. CNTs in the sponge structure are covalently bonded, resulting in a low Young's modulus while at the same time maintaining a good thermal conductivity. This strategy makes it possible to obtain both high deformability and high thermal conductivity, which are difficult to have simultaneously due to their adverse correlation.

Abstract: A yarn tensioning device capable of delivering yarn under tension from a spool to a braiding, weaving or knitting machine consisting of a base and a center rod mounted perpendicular to the said base serving to locates the spool while allowing it to pivotally rotate. The device further includes a pawl jointed to the base either via a pin joint or via a flexural hinge and operates in conjunction with a ratchet solidly attached to the spool. The device further includes a compliant yarn guiding means which ensure that yarn reels off at an essentially constant tension. The yarn reel-off tension can be adjusted by modifying the operating length of a stiffening spring using a screw and jam-nut pair, and by limiting the maximum deflection of the compliant yarn guiding means.

Abstract: A system and associated method measures anomalous diffusion of biomolecules in cell membranes of intact cells and includes a laser that illuminates a cell membrane within an intact cell to express fluorescently tagged biomolecules. The laser photobleaches a region of interest and illuminates the region of interest over time. A detector detects the fluorescence recovery over time within the region of interest to yield fluorescence recovery after photobleaching (FRAP) data. A controller computes the mean square displacement (MSD) of diffusing biomolecules and a time-dependent diffusion coefficient D(t) from a plurality of time points of the FRAP data and determines the anomalous diffusion in the cell membrane.

Abstract: Architectures of millimeter wave fully-integrated frequency-division duplex (FDD) transmitting-receiving (T/R) front-end (FE) modules include a duplexer (DUX), power amplifier (PA), and low noise amplifier (LNA) on a single semiconductor substrate to facilitate the development of system on a chip (SoC) for millimeter wave 5G wireless and next-generation communications applications. The entire balanced DUX module implements TX signals in differential mode, and RX signals in single-ended mode. LNA input is located at the center of a symmetrical plane of the entire FE module, resulting in an inherent ultra-high isolation between the differential PA output ports and the LNA input port across a ultra-wide bandwidth. The DUX can stand alone as a single unit in a system and is used together with external PA and LNA provided in the system, or it can include its own internal PA and LNA to form a DUX FE module.
Abstract: A method for identifying, locating, and mapping targets of interest using unmanned aerial vehicle (UAV) camera footage in GPS-denied environments. In one embodiment, the method comprises obtaining UAV visual data, passing the UAV visual data through a convolutional neural network (CNN) in order to detect targets of interest based on visual features disposed in the UAV visual data, wherein the detection by the CNN defines reference points and pixel coordinates for the UAV visual data, applying a geometric transformation to known and defined pixel coordinates to obtain real-world orthogonal positions; and projecting the detected targets of interest onto an orthogonal map based on the obtained real-world orthogonal positions, all without GPS data.
