Abstract: A system and method for transferring an adversarial attack involving generating a surrogate model having an architecture and a dataset that mirrors at least one aspect of a target model of a target module, wherein the surrogate model includes a plurality of classes. The method involves generating a masked version of the surrogate model having fewer classes than the surrogate model by randomly selecting at least one class of the plurality of classes for removal. The method involves attacking the masked surrogate model to create a perturbed sample. The method involves generalizing the perturbed sample for use with the target module. The method involves transferring the perturbed sample to the target module to alter an operating parameter of the target model.

Abstract: Embodiments herein describe apparatus, systems and methods adapted to monitor underwater wells, boreholes, drill holes, etc. (subsea wells). Depending on embodiment, the apparatus, systems and methods can be configured to capture sensor readings and/or to monitor status of a target subsea wells.

Abstract: A mechanical circulatory support device. The mechanical circulatory support device includes an inner casing defining a fluid flow path, the fluid flow path defines a longitudinal axis. A rotor is mounted within the fluid flow path and configured to rotate about the longitudinal axis. A housing is included, the inner casing and the rotor being substantially disposed within the housing. The housing having a cross-sectional shape in a plane transverse to the longitudinal axis which decreases in thickness extending from a medial position to opposite lateral positions.

Abstract: It has surprisingly been discovered that it is possible to stabilize biomolecules such as RNA, DNA and proteins in biological samples such as cells, tissues, biopsies and blood using deep eutectic solvents (DES). It has also been discovered that DES mixtures can be used to fix and preserve cell morphology in biological samples such as tissue blocks, cancer biopsies and whole blood. This invention describes methods to stabilize and preserve biomolecules, whole cells, tissues, blood and biological samples using DES mixtures.

Abstract: An elevator system comprises a hoistway; an elevator car (12) arranged to move vertically within the hoistway; a plurality of landings opening into said hoistway; and a pit (22) located below a lowermost landing (18). The elevator system further comprises an engineer interface, e.g. a key switch, located at or near the lowermost landing arranged to generate a control signal for moving the elevator car to a predetermined parking position above the lowermost landing thereby allowing access to the pit.

Abstract: An elevator governor includes a selectively powered switch (60) that is activated when an elevator car moves at a speed that exceeds a selected limit. The speed limit is lower than normally expected car speeds during normal elevator operation. The switch (60) is activated by a moving member (66) that moves into a switch-activation position responsive to movement of a rotating member (36) that corresponds to movement of an elevator car. The arrangement allows for a primary governor to prevent elevator speeds from exceeding a first selected limit and a secondary governor to prevent elevator speeds from exceeding a second, lower limit.

Abstract: In a method for preparing copper salts from at least one cupriferous and one additional reactant, the reactants are used to prepare micro-emulsions while employing at least one block polymer, the intermediate products obtained this way are mixed and reacted together so as to form a micro-emulsion. The preparation of the starting micro-emulsion as well as the subsequent joint reaction preferably occur either with ultrasound or in a high-pressure homogenizer. The copper salts obtained this way exhibit a particle size of less than 50 nm, preferably 5 to 20 nm and can be adjusted to specific applications through the appropriate doping of foreign ions.

Abstract: Systems and methods for frequency acquisition and channel tracking in a direct sequence code division multiple access system are described. Frequency estimates are prepared and refined, which estimates are also used in the channel tracking process.

Abstract: A device for detecting sealing defects and for measuring the leakage rate of gaskets placed in parallel relationship on the lateral surface of a gate separating the compartments of a storage pool for nuclear fuel elements has a small volume of free space between the gaskets. This volume is connected by means of a tube with two leakage level detectors placed at different levels which emit a signal when a predetermined water level is attained in the tight volume.
