Abstract: Disclosed are a method of encoding and decoding an audio signal and an encoder and a decoder performing the method. The method of encoding an audio signal includes identifying an input signal, and generating a bitstring of each encoding layer by applying, to the input signal, an encoding model including a plurality of successive encoding layers that encodes the input signal, in which a current encoding layer among the encoding layers is trained to generate a bitstring of the current encoding layer by encoding an encoded signal which is a signal encoded in a previous encoding layer and quantizing an encoded signal which is a signal encoded in the current encoding layer.

Abstract: The present application relates to a scheduling device and method of a mobile communication system. In the packet scheduling method, a base station performs packet scheduling for a terminal station in a mobile communication system, and a transport channel comprising an uplink shared channel (UL-SCH) and a physical channel comprising an uplink grant channel (UL-GCH) between the terminal and the base station are classified into a plurality of channels. In addition, in the packet scheduling method: a) the base station receives scheduling information from the terminal; b) the base station allocates an uplink resource for uplink traffic transmission for terminal based on the received scheduling information; and c) information for the allocated uplink resource is transmitted to the terminal through the UL-GCH of the physical channel.

Abstract: Described here are systems and methods for monitoring airflow changes in a patient's airway during a medical procedure or as a general patient monitoring tool. Doppler ultrasound signals are acquired from an anatomical region within the patient's airway (e.g., a tracheal wall, a cricothyroid ligament, other connective or cartilaginous tissue within the trachea, larynx, or pharynx) and parameters from those Doppler ultrasound signals are compared to baseline parameters, which may include inputting Doppler ultrasound signals to a suitably trained deep learning model or other machine learning algorithm. When a threshold change is detected, an alarm can be provided to a user to indicate respiratory compromise and/or failure, which can include early airway compromise, airway failure, and/or airway obstruction.
Abstract: A tool for driving a component with a knurling pattern around an outer surface of the component is provided. A shaft, with a first end, is in the form of at least a partial cylinder, where the at least partial cylinder has a first inner diameter that is less than an outer diameter of the knurling pattern. Serrations in the shaft have a pattern that matches the knurling pattern, which allow the serration in the shaft to engage with the knurling pattern so that when the shaft is rotated, the component is rotated.

Abstract: Digital imagery can help to quantify seasonal changes in desirable crop phenotypes that can be treated as quantitative traits. Because limitations in precise and functional phenotyping restrain genetic improvement in the post-genomic era, imagery-based phenomics could become the next breakthrough to accelerate genetic gains in field crops. Whereas many phenomic studies focus on exploratory analysis of spectral data without obvious interpretative value, we used field images to directly measure soybean canopy development from phenological stage V2 to R5. Over three years, we collected imagery using ground and aerial platforms of a large and diverse nested association panel comprising 5,555 lines. Genome-wide association analysis of canopy coverage across sampling dates detected a large quantitative trait locus on soybean (Glycine max, L. Merr.) chromosome 19. This QTL provided an increase in yield of 47.3 kg·ha?1.
