Abstract: Provided is a single-axis pointing pure magnetic control algorithm for a spacecraft based on geometrical analysis to realize single-axis pointing control of the spacecraft through the pure magnetic control algorithm in which a magnetic torque is only output by a magnetorquer to interact with a geomagnetic field to generate a control torque. The algorithm uses a spatial geometry method to obtain an optimally controlled magnetic torque direction, thereby designing a PD controller. The problem that the traditional magnetic control method is low in efficiency and even cannot be controlled is overcome. The algorithm is simple and easy, can be used in the attitude control field of spacecrafts, and achieves the pointing control in point-to-sun of a solar array and point-to-ground of antennae.

Abstract: An anti-CD47 monoclonal antibody and use thereof. The provided anti-CD47 monoclonal antibody can effectively inhibit tumor growth. Blocking human SIRP and human CD47 signals may enhance macrophage phagocytosis of tumor cells, prevent the tumor cells from escaping a tumor immune defense system, and have an anti-tumor function. Blocking association between the CD47 on a tumor cell surface and the SIRP on a macrophage surface may block a “do not eat me” signal from the tumor cells, promoting tumor cell recognition and uptake of macrophages, and thereby facilitating tumor cells to be phagocytosed. The association between the CD47 on a tumor cell surface and the SIRP on a macrophage surface is a common “do not eat me” signal. The anti-CD47 antibody, as a very promising target in the tumor immune system, will play a powerful and effective role in human cancer therapy.

Abstract: A method of operating a talk group server to control a virtual talk group member. During operation, the talk group server determines an assignment for a virtual talk group member to join a first talk group and communicate on behalf of a talk group member associated with a second talk group. The talk group server obtains user profile associated with the talk group member and causes the virtual talk group member to join the first talk group using the user profile associated with the talk group member. The talk group server then controls the virtual talk group member to perform the assignment by generating audio communications as a function of the user profile associated with the talk group member and transmitting audio communications on the first talk group.
