Abstract: A computer system includes an ensemble moving target defense architecture that protects the computer system against attack using one or more composable protection layers that change each churn cycle, thereby requiring an attacker to acquire information needed for an attack (e.g., code and pointers) and successfully deploy the attack, before the layers have changed state. Each layer may deploy a respective attack information asset protection providing multiple respective attack protections each churn cycle, wherein the respective attack information asset protections may differ.

Abstract: All existing state-of-the-art high resolution millimeter wave imaging systems experience a trade off between image acquisition time and transceiver array complexity. The proposed dual reflector antenna breaks this trade-off by drastically reducing the array formation time while maintaining the relative simplicity that comes with using a single transceiver element. It consists of a dual mode horn feed, a rotating ellipsoidal sub-reflector and a conic main reflector. The rotating sub-reflector creates a virtual phase center that rotates about an axis to produce a synthetic circular array with a diameter of 120?. The main reflector redirects the beams from each of these virtual phase centers to overlap and illuminate the scene over a wide field of view. The proposed system can reduce the image acquisition time to the order of milliseconds/seconds which makes real-time SAR imaging a practical alternative to MIMO and phased arrays at millimeter-wave and sub-millimeter-wave frequencies.

Abstract: Disclosed are a system and methods for preventing dendrite growth in an electrochemical cell through the use of a protective layer. The electrochemical cell may comprise an anode, a cathode, an electrolyte, and a protective layer, wherein the protective layer is capable of producing a voltage. The voltage produced can selectively shield metal ions from certain regions of the protective layer. This shielding can result in a more uniform flux of metal ions being transferred across the electrode-electrolyte interface in subsequent electrodeposition and electrodissolution processes. As a result, an electrode with such a protective layer can exhibit improved performance and durability, including markedly lower overpotentials and largely improved metal (e.g., lithium) retention.

Abstract: Methods and systems generate synthetic late gadolinium enhancement (LGE) magnetic resonance images using a magnetic resonance fingerprinting (MRF) acquisition. From a single acquisition, MRF image data is obtained, including co-registered T1 and T2 tissue property maps. Different tissue regions of interest are identified, such as viable myocardium, scar, and blood and T1 and T2 values for each are determined. Based on these, different sets of pulse sequence parameters are determined, e.g., using different synthetic image contrast models receiving the MRF image data. Synthetic LGE images at different contrasts are generated as a result, including a synthetic bright-blood LGE image, a synthetic dark-blood/gray-blood LGE image, and a synthetic optimized imaged.

Abstract: Integrated Optical Phased Array device is a good potential solution for the solid-state LIDAR technology in the application of autonomous driving technique. However, some difficulties still limit the development of OPA devices, one of them is the conflict between the requirement of fewer units in the phase-tuning system and more elements in the emitting system. The present disclosure provides an approach of a Phase-Combining Waveguide Doubler (PCWD) to address this issue. This device can double the waveguide number without any phase mismatch. It enables the capability to control 2N?1 emitting elements with N phase shifters. The device is competitive to any grating coupler array based or end-fire based emitting method, which can potentially satisfy the requirement of a sub-wavelength pitch.
