Abstract: Embodiments disclosed herein relate to an autonomous work excavator and an operation method therefor. According to an embodiment, an excavator comprises a front work device including an arm, a boom, and a bucket; a sensor device configured to collect state information of the excavator and information related to the surrounding environment; and a processor electrically connected to the front work device and the sensor device. The processor is configured to perform a digging operation based on a work instruction such that soil is loaded in the bucket; calculate a zero-moment point of a force acting on the excavator based on mass information on at least a portion of the front work device after the digging operation has been performed; and obtain a work trajectory for processing the soil loaded in the bucket by using the ZMP and the information related to surrounding environment.

Abstract: A method includes generating, by a neural network having a plurality of layers, final feature vectors of one or more frames of a plurality of frames of an input video, while sequentially processing each of the plurality of, and generating image information corresponding to the input video based on the generated final feature vectors. For each of the plurality of frames, the generating of the final feature vectors comprises determining whether to proceed with or stop a corresponding sequenced operation through layers of the neural network for generating a final feature vector of a corresponding frame, and generating the final feature vector of the corresponding frame in response to the corresponding sequenced operation completing a final stage of the corresponding sequenced operation.

Abstract: A processor-implemented posture determination method includes: estimating a rotational acceleration of a timepoint based on an angular velocity measured by a first sensor at the timepoint and a determined center of rotation of a previous timepoint; correcting an acceleration measured by a second sensor at the timepoint based on the rotational acceleration; and determining a center of rotation of the timepoint and a posture of the timepoint based on the corrected acceleration and an estimated posture of the timepoint.

Abstract: The present invention relates to a method for inhibiting myeloid-derived suppressor cells or treating cancer comprising administering a pharmaceutical composition containing decitabine or its pharmaceutically acceptable salt as an active ingredient. The decitabine suppresses creation of a cell population of myeloid-derived suppressor cells (MDSC) created in spleen and bone marrow in tumorigenic mice and induces apoptosis of the MDSC cell population. Therefore, the decitabine may be useful as agents for treating MDSC-related diseases and anticancer immunotherapy, or an anticancer supplement.

Abstract: Disclosed is a sound data processing system including a plurality of sound collecting terminals and a server. Each of the plurality of sound collecting terminals includes: a sound collecting means that collects a sound and has an orientation direction, and a communication module that transmits sound data corresponding to the sound collected by the sound collecting means and supplementary data including position data of a position of a corresponding sound collecting terminal and orientation direction data corresponding to the orientation direction of the sound collecting means via a network. The server receives the sound data and the supplementary data transmitted by the plurality of sound collecting terminals through the network and determines a position of a source that emits the sound collected by the sound collecting means on the basis of the sound data and the supplementary data.

Abstract: Provided are encoded polymeric microparticles and a multiplexed bioassay using the encoded polymeric microparticles. Each of the encoded polymeric microparticles includes an encoded polymeric microparticle core and a silica shell surrounding the microparticle core. Further provided is a method for producing encoded polymeric microparticles. The method includes: mixing a photocurable material with a linker having a functional group polymerizable with the photocurable material and an alkoxysilyl group; applying patterned energy to cure the mixture, followed by encoding to obtain encoded polymeric microparticle cores; and treating the encoded polymeric microparticle cores with a silica precursor to form a silica shell on each encoded polymeric microparticle core.
