Abstract: The present invention relates to processes for preparing a Compound (1): or a pharmaceutically acceptable salt or solvate thereof. Compound (1) is useful as in many pharmaceutical agents, especially is useful as key intermediate in the synthesis of certain SARS-CoV-2 3CLpro inhibitors.

Abstract: The present invention features crystalline forms of Compound I, including polymorphs and pseudopolymorphs, which are useful in the preparation of pharmaceutical compositions.

Abstract: A uracil compound containing a carboxylate fragment, a preparation method therefor, and a herbicidal composition and use thereof are provided. The preparation method includes a contact reaction between a carboxylic acid compound and different substituted alcohol, halogenated, or sulfonate compound in a presence of a solvent. The uracil compound containing a carboxylate fragment provided by the present invention has better herbicidal activity compared with the prior art.

Abstract: Embodiments herein generally relate to a method and system for monitoring and tracking animals in an animal enclosure. In at least one embodiment, the method comprises monitoring for user activity in respect of a camera system associated with the animal enclosure; if user activity is detected: receiving a user-generated command to control the camera; and transmitting the user-generated command to the camera system, if user activity is not detected, controlling the camera system to search and track for one or more target animals in the animal enclosure.

Abstract: The present disclosure provides systems and methods for imaging based on the generation and use of mismatched coded excitation signals. Cross-correlation properties of the received signal reveal the location and/or timing and/or properties of the source. The use of mismatched signals enables spatial and/or temporal and/or functional encoding of the transmitted signals. In some embodiments, high-speed imaging may be performed by employing mismatched codes for spatial and/or temporal encoding, and by employing a subset of transducer elements as transmitters, and another subset of elements as receivers. Various example embodiments of different types of mismatched codes are provided, including codes that employ multiple frequency chirps, codes that employ concatenated multi-frequency binary phase-coded waveforms, and chirped binary phase-coded waveforms.

Abstract: Methods, systems, and apparatus, including computer program products, for aligning user interface elements arranged in multiple columns in a user interface. In one aspect, a method includes identifying a group of columns in a user interface, where each column in the group includes one or more user interface elements arranged in a sequence from a top of the column to a bottom of the column; comparing heights of first sequences of one or more user interface elements in a first column to heights of second sequences of one or more user interface elements in a second column; and adjusting the heights of the first sequences to align the first sequences with the second sequences by adjusting the heights of user interface elements in the first sequences, where adjustments to each user interface element in the first sequences are each less than a threshold adjustment value.

Abstract: A robust system, apparatus, and method for precise in-house positioning utilizing RFID (Radio Frequency Identification) technology are described in this invention. The in-house environment is partitioned into separate locations, and a set of RFID tags are scattered in the environment. Reading patterns of RFID tags are collected at each location by an RFID reader as samples. Pattern recognition and classification methods are used, when human, vehicle, or other carrier move around the environment with an RFID reader to estimate its physical location based on the reading pattern. The precision can be within one meter. The method is adaptive to different tag distribution, reader range, defective tags, and other physical constraints.
