Abstract: Disclosed is a system for stabilizing a power distribution network. The network is supplied at least partially by a renewable energy source. The system comprises a bidirectional AC-DC power conversion system between a supply 5 side distribution network and a load side grid. for converting a supply side AC voltage, at a supply side frequency. to a load side DC voltage; a voltage regulator for regulating the load side DC voltage; and a supply side control loop comprising at least one of a frequency control loop and a voltage control loop for making a measurement of a respective one of the supply side frequency and 10 supply side AC voltage. and controlling bidirectional power transmission between the bidirectional AC-DC power conversion system and one or more DC loads connected to the load side grid. based on the measurement from the respective frequency control loop and/or voltage control loop.

Abstract: A method for designing a channel estimation and data detection networks is provided herein. The problem of channel estimation for linear systems has effectively been solved—not the case for non-linear systems. A deep learning framework for channel estimation, data detection, and pilot signal design is described to address the nonlinearity in such systems.

Abstract: Disclosed are methods of protecting cells, especially non-vascular system, non-hematopoietic cells and tissues, from apoptosis and enhancing their engraftment, survival, and/or persistence by providing enhanced levels of PIM activity for the cell, including PIM-1 activity. Also disclosed are cells that have been engineered to express enhanced levels of PIM kinase, and methods of administering those cells to vertebrates.

Abstract: The invention is directed to compositions, e.g., cell-based and multiplexed platforms, to screen for small molecule drugs that inhibit enzymes such as proteases, e.g., viral proteases, e.g., HIV proteases; and methods for making and using these compositions. The invention provides compositions and methods for identifying compositions, e.g., drug molecules, that can inhibit proteases, e.g., viral proteases such as HIV proteases. In alternative embodiments, the invention provides cell-based platforms or assays to screen for compositions, e.g., small molecules or drugs, that inhibit or modify the activity of enzymes such as calcium-dependent protein convertases involved in HIV envelope protein processing, including cleavage of the HIV gp160 envelope precursor, resulting in gp120 and gp41 envelope products. In one embodiment, the invention provides a cell-based or multiplexed platform for monitoring the activity of enzymes, e.g., proteases such as viral proteases.
