Abstract: The present invention relates to a thermoplastic composition, a thermoplastic composite, and a method for producing the thermoplastic composite. In the method for producing the thermoplastic composite, a polymer, an acid-modified lignin with a specific element content and a compatibilizer with a specific melt flow index and a specific maleic anhydride content are used to produce the thermoplastic composite. Hydroxy groups of the acid-modified lignin react with maleic anhydride groups of the compatibilizer to generate ester bonds via an in-situ reaction catalyzed by acidic groups of the acid-modified lignin to enhance compatibility between the polymer and the lignin, thereby increasing a mechanical strength of the resulted thermoplastic composite.

Abstract: A method of waste treatment includes treating partially-dewatered matrix with a first electron-beam radiation dose. The treated partially-dewatered matrix is transferred to a digester where the treated partially-dewatered matrix is subjected to anaerobic digestion. Biogas is recovered from the treated partially-dewatered matrix during the anaerobic digestion. The treated partially-dewatered matrix is dried and subjected to a second electron-beam radiation dose.

Abstract: A system and associated method measures anomalous diffusion of biomolecules in cell membranes of intact cells and includes a laser that illuminates a cell membrane within an intact cell to express fluorescently tagged biomolecules. The laser photobleaches a region of interest and illuminates the region of interest over time. A detector detects the fluorescence recovery over time within the region of interest to yield fluorescence recovery after photobleaching (FRAP) data. A controller computes the mean square displacement (MSD) of diffusing biomolecules and a time-dependent diffusion coefficient D(t) from a plurality of time points of the FRAP data and determines the anomalous diffusion in the cell membrane.

Abstract: Architectures of millimeter wave fully-integrated frequency-division duplex (FDD) transmitting-receiving (T/R) front-end (FE) modules include a duplexer (DUX), power amplifier (PA), and low noise amplifier (LNA) on a single semiconductor substrate to facilitate the development of system on a chip (SoC) for millimeter wave 5G wireless and next-generation communications applications. The entire balanced DUX module implements TX signals in differential mode, and RX signals in single-ended mode. LNA input is located at the center of a symmetrical plane of the entire FE module, resulting in an inherent ultra-high isolation between the differential PA output ports and the LNA input port across a ultra-wide bandwidth. The DUX can stand alone as a single unit in a system and is used together with external PA and LNA provided in the system, or it can include its own internal PA and LNA to form a DUX FE module.

Abstract: In some examples, a method performed by a drilling rig control center, includes receiving raw data for a first time segment, the raw data related to a drilling operation. In addition, the method includes deriving first drilling state measurements based on the raw data of the first time segment. Further, the method includes deriving first formation state measurements based on the raw data of the first time segment. The method also includes correlating the first derived drilling and formation state measurements of the first time segment with a second derived drilling and formation state measurements of a second time segment. Still further, the method includes generating a control response based on the correlation.
