Abstract: Embodiments of the present invention provide systems and methods for re-balancing the stability of a SRAM cell. Embodiments of the present invention identify SRAM cells with negative voltage threshold margins and write a “zero” state bit with in the bi-stable flip-flop of the SRAM. Raising the voltage of the CMOS set containing the “zero” state bit and selective transistor biasing, skews the “zero” state bit towards the complementary “one” state bit. This induces an increase voltage thresholds of the identified SRAM cells.

Abstract: An application may store data to a dataset comprising a plurality of volumes stored on a plurality of storage systems. The application may request a dataset image of the dataset, the dataset image comprising a volume image of each volume of the dataset. A dataset image manager operates with a plurality of volume image managers in parallel to produce the dataset image, each volume image manager executing on a storage system. The plurality of volume image managers respond by performing requested operations and sending responses to the dataset image manager in parallel. Each volume image manager on a storage system may manage and produce a volume image for each volume of the dataset stored to the storage system. If a volume image for any volume of the dataset fails, or a timeout period expires, a cleanup procedure is performed to delete any successful volume images.

Abstract: An active repeater device includes a primary sector and one or more secondary sectors, receives a first beam of input RF signals. A first set of analog baseband signals, are generated based on received first beam of input RF signals. The first set of analog baseband signals are converted to a first set of coded data signals and control information is extracted from the first set of coded data signals by decoding only a header portion of the first set of coded data signals without demodulation of data portion of the first set of coded data signals. Based on the extracted control information, the first set of coded data signals are transmitted as beams of output RF signals to remote user equipment. The transmission is independent of demodulation of the data portion within the active repeater device to reduce latency for transmission of the first set of coded data signals.

A value of a second signal parameter is calibrated based on a matching of the second signal parameter in the second transmit path relative to the second signal parameter in the first transmit path.

Abstract: The present invention relates to vaccines containing enveloped viruses whose envelopes have been depleted of lipids using methyl ?-cyclodextrin (MBCD). Delipidation of enveloped viruses in a two-step process abolishes the infectivity of those viruses, which allows delipidated viruses to be used safely in vaccines. Use of MBCD to deplete lipids such as cholesterol, in contrast to other methods, results in viruses with less than 20% of the cholesterol of an untreated virus but such delipidated viruses retain at least 85% of the protein content of an untreated virus. Delipidation by MBCD also preserves the immunogenicity of the viral proteins. The present invention of using MBCD treatment in a two-step process to delipidate enveloped virus represents a new alternative for generation of inactivated viruses which are incorporated into effective vaccines.
