Abstract: A method for constructing a dynamic security region of a power grid based on an extended phase trajectory theory includes: obtaining a system transient stability condition and a power angle leading generator group by transient simulation of an initial operation point of a system; for generators in the leading generator group A, changing output of each of the generators to search for a dominant instability critical point; calculating the reciprocal of the slope of the tangent line of the trajectory of n swings of an extended phase plane based on angular velocity-angular acceleration in a fourth quadrant, and changing a small disturbance output of the generator at the dominant instability critical point to solve a sensitivity of the extended phase trajectory; and constructing a multi-modal practical dynamic security region based on the extended phase trajectory.

Abstract: The invention relates to antiviral compounds, compositions comprising antiviral compounds, and methods of use. In particular, the antiviral compounds are cytidine triphosphate synthetase 1 (CTPS1) inhibitors that are effective in treating and/or preventing viral infection and in particular, SARS-CoV-2 infection and/or COVID-19 disease.

The camera includes a ball-head shell; a vertical stepping motor and a motor bracket are arranged in the ball-head shell; a first ear pad and a first motor shaft are arranged on the vertical stepping motor; a vertical shaft sleeve is arranged on the motor bracket; the first motor shaft is fixedly connected to the vertical shaft sleeve through a machine screw; the hidden bidirectional rotary camera further includes a base shell; a horizontal stepping motor is arranged in the base shell; a second ear pad and a second motor shaft are arranged on the horizontal stepping motor; a horizontal shaft sleeve is further arranged at the bottom of the motor bracket; the second motor shaft is fixedly connected to the horizontal shaft sleeve through a machine screw.

Abstract: A composition and method for a microtexture hydrophobic or superhydrophobic coating. The microtexture coating includes a coating layer disposed on a substrate with hydrophobic or superhydrophobic particles dispersed on top of or partially embedded in the coating layer to form an outer layer. The outer layer exhibits water repellant properties. Use of the microtexture coating permits large scale, durable hydrophobic or superhydrophobic coating applications. The microtexture coating is a useful for application on wind turbines, airplanes, solar panels, windows, or cooling systems.

Abstract: The present invention provides an antibody and a fusion protein for treating coronaviruses and use thereof. The 6-HB interference polypeptide in the fusion protein of the present invention and a part of an antibody or an antigen-binding fragment work synergistically to prevent fusion of SARS-COV or SARS-COV-2 virus particles with cells, and mediate phagocytosis and clearance of the virus particles by immune cells.

Abstract: The present invention relates to the field of bio-pharmaceuticals and provides an anti-CLDN18.2 antibody. Related preparation methods and related uses are described. The antibody of the present invention or related an antigen-binding fragment can specifically bind to CLDN18.2 with a strong binding capacity. After humanization, the antibody or the antigen-binding fragment has a strong ADCC effect and CDC activity and has good pharmaceutical prospects.

Abstract: A communications method includes: sending a scheduling request to a terminal device through a PDCCH, where the scheduling request indicates the terminal device to send data to a network device based on a preset time interval; in response to not receiving the data that is sent by the terminal device through a PUSCH, determining, based on measurement gap configuration information of the terminal device, whether a time point at which the terminal device does not send the data is within a measurement gap window; and if it is determined that the time point at which the terminal device does not send the data is within the measurement gap window, sending, to the terminal device, a redundancy version number used for a next HARQ retransmission.

Abstract: A composition for a microtexture hydrophobic or superhydrophobic coating. The microtexture coating includes a coating layer disposed on a substrate with hydrophobic or superhydrophobic particles dispersed on top of or partially embedded in the coating layer to form an outer layer. The outer layer exhibits water repellant properties. Use of the microtexture coating permits large scale, durable hydrophobic or superhydrophobic coating applications. A method of applying a coating to a substrate creating a hydrophobic or superhydrophobic surface that includes applying a polymer material or an adhesive material to the substrate creating a polymer coating layer having a top surface; initially curing the applied coating layer for a specified amount of time allowing the coating layer to partially cure; and applying a solution, at a specified velocity, containing hydrophobic particles or superhydrophobic particles on top of the partially cured coating layer.
