Abstract: System and method for guiding a drill using a subsurface model generated by successive full waveform inversions (FWI) on surface data and seismic-while-drilling (SWD) data. A server receives surface data from at least one surface sensor that records elastic energy radiated from surface seismic source and SWD data from at least one surface or at least one subsurface crosswell sensor (i.e., deployed in a nearby well). The server also receives top-drive measurements. A drillbit source signature estimation is performed, on the SWD data, by the server by blind deconvolution or by using drill string modeling and top-drive measurements. The server then performs FWI on the surface data by using the background subsurface velocity obtained by kinematic analysis of surface seismic data, to obtain an updated approximation of the subsurface velocity. The new approximation along with the drillbit source signature is then used when performing FWI on the SWD data.

Abstract: In an industrial automation system including a first and a second wireless communication device communicating with each other via a cellular network, the first wireless communication device obtains, while the first wireless communication device is attached to a first base station of the cellular network, knowledge about to which base station the second wireless communication device is attached and if the second wireless communication device is attached to a second allowable base station, the first wireless communication device detaches from the first base station and attaches to the second base station.

Abstract: Disclosed are proteolysis-targeting chimeric molecules (PROTACs) that induce degradation of c-MYC protein. The disclosed PROTACs typically include a first targeting moiety that binds to c-MYC (Mc-MYC) which may be derived from a substituted heterocycle that binds to c-MYC such as a substituted pyrazole. The first targeting moiety typically is linked via a bond or a linker (L) to a second targeting moiety that binds to an E3 ubiquitin ligase (ME3). As such, the disclosed PROTACS may be described as having a formula Mc-MYC-L-ME3 or ME3-L-Mc-MYC.
