Abstract: A processor-implemented method with virtual object rendering includes: determining a plurality of predictive trajectories of a first object according to a Gaussian random path based on a high-level model that is trained by hierarchical reinforcement learning; determining direction information of a second object according to subgoals corresponding to the predictive trajectories based on a low-level model that is trained by hierarchical reinforcement learning; determining direction information of the second object according to a subgoal corresponding to one of the predictive trajectories based on an actual trajectory of the first object; and rendering the second object, which is a virtual object, based on the determined direction information.

Abstract: The present invention relates to thermally and chemically stable quantum dots encapsulated with functional polymeric ligands, a thermally stable quantum dot optical film using the encapsulated quantum dots, and a method for preparing the encapsulated quantum dots. The coating of the surface of the quantum dots with the polymer stabilizes the quantum dots and improves the durability and dispersibility of the quantum dot optical film, achieving markedly improved efficiency of photoluminescent quantum dot devices. Therefore, it is anticipated that the present invention will pave the way for practical use of quantum dots in a variety of light-emitting applications, particularly in high power light-emitting sources, to find commercial application in various fields, including displays, bioimaging, lightings, and photovoltaic cells.

Abstract: This disclosure relates to the 5th generation (5G) or pre-5G communication system for supporting a higher data rate after the 4th generation (4G) communication system such as Long Term Evolution (LTE). The method for operating the core network in a wireless communication system according to this disclosure comprises the processes of determining the content to store in the terminal based on the location information of the terminal, transmitting the content transmission command to the base station so as to transmit the content to the terminal in response to the determination, checking whether the terminal has entered the overload cell, and forming a D2D communication link between the terminal and another adjacent terminal when it is identified that the terminal has entered the overload cell.

Abstract: A device and method for absorbing electromagnetic waves can include a honeycomb sheet formed by a plurality of interconnected hexagon cells arranged in rows. The hexagon cells are made up of sidewalls, each sidewall formed by two surfaces that converge at a top of the sidewall and diverge from the top to a bottom of the sidewall such that a thickness of the sidewalls increases from top to bottom and an angle forms between the two surfaces at the top of the sidewall. In an example, the angle is about 8 degrees. The honeycomb sheet can be coated with a magnetic, composite coating to increase electromagnetic shielding. An example coating includes magnetic multi-granular nanoclusters (MGNC) and multi-walled carbon nanotubes (MWCNT). A base layer can be attached to the honeycomb sheet for mechanical stability and additional absorption. The device is suitable for radar absorbing materials (RAM) for aerospace and military applications.
