Abstract: A method for increasing the yield of Amadori rearrangement products (ARP) based on a mechanism in which addition of tea polyphenols to deoxyosones inhibits degradation of the ARP. The method includes the following steps: dissolving and mixing amino acid, sugar and tea polyphenol in water, and adjusting a pH value; placing the obtained mixed solution in a reaction flask, and heating the mixed solution at a constant temperature in a water bath to obtain a reaction solution; and performing vacuum decompression dehydration reaction at a constant temperature; after the reaction is completed, using an ice bath to terminate the reaction to obtain a solid reactant, and redissolving the solid reactant in water to obtain an ARP solution. This method promotes the formation of ARP and inhibits degradation of ARP, so that ARP is accumulated and enriched in a large amount (80% and above yield).

Abstract: Methods, systems, and techniques for performing automatic source code generation for use in a data transformation process. A computer obtains a data file comprising data transformation rules. Using those rules, the computer automatically generates computer source code for use in a data transformation process to transform source data into target data. The source data may, for example, be raw data from a data lake, and the computer source code may be Scala computer code for execution within an Apache Spark™ framework. The data lake may execute the computer source code to transform the raw data stored in the data lake into the target data, and the target data may then be stored in the data warehouse.

Abstract: A method for preparing an intermediate by a reduced glutathione-indicated amino acid Maillard reaction is provided. The method includes a two-stage reaction at an increased temperature. A reduced glutathione is added after different times of a low-temperature reaction, and a subsequent Maillard reaction is effectively inhibited on a basis wherein a substance is interacted with an intermediate degradation product to reduce a formation of colored substances. Comparing with a browning of Maillard products after a high-temperature stage, a reaction time with a best color inhibition effect is found to be the optimal preparation condition of the intermediate, and the intermediate is prepared in an aqueous medium at a low temperature under this optimal preparation condition. The method uses the water soluble reduced glutathione as a tracer to improve a tracing accuracy comparing to cysteine.

Abstract: Using a distance sensor, a set of distances to a target object is measured, a distance in the set being measured at a time. From the set of distances and corresponding times, a trajectory of the target object is predicted. Based on receiving a signal identifying a friendly device, a correlation of the trajectory with a trajectory of the friendly device is determined. Responsive to the trajectory being predicted to intercept a defined volume around the distance sensor and responsive to the correlation being above a threshold degree of correlation, the target object is classified as a threat. Responsive to the trajectory being predicted to intercept a defined volume around the distance sensor and responsive to the correlation being below a threshold degree of correlation, a threat level corresponding to the target object is identified based on the trajectory of the target object and trajectory of the friendly device.

Abstract: Aspects determining anomalous events, wherein processors determine a trajectory of tracked movement of an object through an image field of a camera partitioned into a matrix grid of different local units. The aspects generate anomaly confidence decision values for image features extracted from video data of the tracked movement of the object as a function of fitting extracted image features to normal patterns of local motion pattern models defined by dominant distributions of extracted image features. The aspects further extract trajectory features from the video data relative to the trajectory of the tracked movement of the object, and generate global anomaly confidence decision values for the object trajectory as a function of fitting the extracted trajectory features to a normal learned motion trajectory model. The aspects determine anomalous events as a function of the generated global anomaly confidence decision value and the anomaly confidence decision values.
