    Abstract: Systems and methods to identify new protein targets of a chemical compound or its derivatives were described. The methods can be used for detection of new binding partners as long as the chemical compound can covalently bind to the protein targets. Once protein targets are resolved, information related to new protein targets can then be used to couple with real-world patient data such as adverse events, efficacy data, and disease correlation data to deduce real-world evidence. Systems collectively with all this information can aide clinical development and use of pharmaceutical drug. Methods are provided for detection of covalently bound phenyl vinyl sulfone (PVS) or its derivatives, and afatinib or its derivatives. Furthermore, generation of antiserum recognizing carrier bound PVS or carrier bound afatinib is described.

  • Publication number: 20230099551
    Abstract: The relative position of a user equipment (UE) within a vehicle is determined using angular measurements, such as angle of arrival (AOA), and optionally ranging measurements, with respect to a number of wireless transceivers within the vehicle using wideband signals. The relative position of the UE with respect to a personal zone or the steering wheel may be determined based on known positions of the wireless transceivers. If the UE is determined to be within the personal zone, at least one functionality of the UE is restricted to avoid driver distraction and, optionally, the operation autonomous driving of the vehicle adjusted. If the UE is worn on the driver's wrist the relative position of the UE with respect to the steering wheel may be similarly determined and operation of the vehicle modified if the UE is determined to be outside a threshold distance from the steering wheel.

  • Patent number: 11600822
    Abstract: A cathode material and a fabricating method thereof, and a lithium-ion battery are described. The cathode material is a 1D metal-organic coordination polymer of [CuL(Py)2]n, and its structure is formed by interlinking organic ligands (L) and metals (Cu). The cathode material can use redox active sites on both the metal and organic ligand to carry out multi-electron transfer. A C?N bond contained in L together with a benzene ring of L in an adjacent polymer chain form a weak interaction of C?N . . . ?. In addition, a Py of adjacent polymer chains also have an interaction of ? . . . ?. Therefore, [CuL(Py)2]n chains are closely interlaced and packed, but there is still enough regular space for lithium ions to enter and exit quickly, so it can be charged and discharged rapidly and exhibits high power density.
