Abstract: Exemplary embodiments of the present disclosure are directed to a machine learning-based receiver that operates on the basis of a wide-band RF front-end. The RF front-end outputs clean IQ data to a SPectrum-Analysis-Isolation-Synthesis (SPAIS) system in order to collect analytics of signals present within the monitored band of frequencies, including signal center frequencies, bandwidth and power. The SPAIS system pre-processes the captured wideband IQ data in order to locate frequency bands with signal energy, isolate and synthesize the located frequency bands in corresponding IQ data for individual processing by a neural network with high classification accuracy.

Abstract: The present invention provides an improved process for the preparation of high purity glucagon comprising the use of Xmb-protected amino acids, wherein may Xmb include, e.g., 2,4,6-trimethoxybenzyl, 2,4-dimethoxybenzyl, or 2-hydroxy-4-methoxybenzyl. The process also comprises the use of building blocks such as pseudoprolines to avoid aggregation and obtain the product in high yield and purity.

Abstract: An exemplary detection apparatus includes a housing having one or more sensors of one or more sensor types, an optional port for detachably mounting one or more of the sensors, and an optional motive system associated with a mode of transport for movement in an area of interest. A sensor circuit receives a signal originating from the one or more sensors, identifies the signal, optionally processes the signal data, and packages the raw signal data or processed signal data, as applicable, for transmission over a network. A control circuit establishes communication with the network for sending or receiving sensor data to/from other devices connected to the network, and controls the motive system for moving the apparatus to locations in the area of interest.

Abstract: A method of processing a radio frequency signal includes: receiving the radio frequency signal at an antenna of a receiver device; processing, by a radio frequency front-end device, the radio frequency signal; converting, by an analog-to-digital converter, the analog signal to a digital signal; receiving, by a neural network, the digital signal; and processing, by the neural network, the digital signal to produce an output.

Abstract: A compact chromatographic device and use thereof are disclosed. The device permits trapping of a first analyte while permitting passage of other analytes, followed by trapping of a second and subsequent analytes in an orderly series. Each analyte is trapped sequentially by a different chromatographic media. The process allows detection and/or measurement of each analyte without interference from other analytes previously trapped, enabling assays of analytes in a compact device without elution of analytes from the device. The compact device is pre-assembled and ready to use in a point of care or non-laboratory setting.
