Abstract: The systems and methods use a gradient boosted decision tree, which may be trained in data sparse environments. The system also uses a data transformation step to collapse complex data into a standardized feature input (e.g., a fixed length feature input) that may be processed by the model with a constant (or near-constant) lookup time and with minimal latency. Finally, the system generates a dual variable output that provides both a metric of whether a communication is fraudulent and/or unauthorized as well as a confidence level of that determination.

Abstract: A system and method for determining a value of a hand written monetary tip amount on a paper payment receipt is provided. One embodiment scans, using a scanner, a paper payment receipt having a hand written monetary tip amount thereon; generates scan data that corresponds to the scanned paper payment receipt: identifies text from the scan data, wherein the identified text includes hand written text and machine printed text; discriminates the hand written text from the machine printed text; and determines a value of the hand written monetary tip amount based on the identified hand written text.

Abstract: Disclosed herein are methods of disrupting cell-to-cell communication. An exemplary method comprises transmitting one or more microwave signals to a communication molecule located in an environment having a plurality of cells. The one or more microwave signals can comprise a first microwave signal and a second microwave signal. The first microwave signal can have a first frequency corresponding to frequency of a first peak in a microwave spectrum associated with rotational modes of the communication molecule. The second microwave signal can have a second frequency corresponding to a frequency of a second peak in the microwave spectrum associated with the rotational modes of the communication molecule.

Abstract: An exercise device characterized by a wide hand surface (1) positioned at a downward angle with a design that allows the user to grip the underside (3) for greater stability and to position the hands in any direction necessary to perform exercises with reduced strain on the wrists and palms. The large surface area of the hand surface comfortably fits an adult palm to eliminate painful pressure points in the palm. The downward angle of the hand surface decreases the angle between the back of the hand and the forearm found in a traditional push-up position to eliminate strain associated with exercises like push-ups, planks, mountain climbers and even chest dips. The ability to grip the underside of the hand surface provides additional stability during exercise.

Abstract: Systems and methods include directing limited frequencies of microwave signals toward target molecules, driving a motion of the target molecules to impact molecular recognition. In one implementation, a microwave spectra associated with the rotational modes of a target molecule is obtained. From peaks in the spectra, a mode of molecular movement is identified and a microwave signal profile is generated for driving a motion of binding portions of the molecule associated with the identified mode. Microwave signals are generated based on the signal profile for output by antennas. For example, the microwave signals can be can be used to impede the binding of quorum sensing molecules by receptors of P. aeruginosa. In one implementation, the antennas can be placed in a catheter for placement in a patient. In another implementation, the antennas can be placed in a sleeve or other device for use adjacent to the skin of a patient.

Abstract: A thin-film bulk acoustic wave delay line device providing true-time delays and a method of fabricating same. An exemplary device can comprise several thin-film layers including thin-film transducer layers, thin-film delay layers, and stacks of additional thin-film materials providing acoustic reflectors and matching networks. The layer material selection and layer thicknesses can be controlled to improve impedance matching between transducers and the various delay line materials. For example, the transducer layers and delay layers can comprise piezoelectric and amorphous forms of the same material. The layers can be deposited on a carrier substrate using standard techniques. The device can be configured so that mechanical waves propagate solely within the thin films, providing a substrate-independent device. The device, so constructed, can be of a small size, e.g. 40 ?m per side, and capable of handling high power levels, potentially up to 20 dBm, with low insertion loss of approximately 3 dB.

Abstract: A drawer for an airline trolley, which has a generally rectangular tray, is closed by a lid. The lid has a flap which is openable, and the drawer has a lock unit with which the flap engages. The lock unit is lockable by a breakable seal. The flap can be hinged about a line extended across the lid at a position forward of the back of the tray. The flap can be connected to the sides of the tray by webs which fold under the flap in its closed position, the webs preventing access to the interior of the tray under the lid. The flap can have a catch at its forward end which engages in a lockable chamber on the front of the drawer, a breakable seal being insertable into the chamber to engage the catch.
