Abstract: Proposed are an ultra-low jitter low-power phase-locked loop using a power-gating injection-locked frequency multiplier-based phase detector (PG-ILFM PD) and an operating method thereof. The proposed PG-ILFM PD includes a replica voltage controlled oscillator (R-VCO) configured to cut off the power supply of the R-VCO repeatedly based on a reference signal SREF and a fundamental sampling phase detector (FSPD) configured to receive an output signal SILFM of the R-VCO as a reference signal for sampling and detect a phase error of a main voltage controlled oscillator (M-VCO).

Abstract: An image processing device according to one embodiment estimates optical flow information, pixel by pixel, on the basis of a reference image and input images of consecutive frames, and estimates a term corresponding to temporal consistency between the frames of the input images. The image processing device determines a mesh on the basis of the term corresponding to temporal consistency and the optical flow information, and transforms the reference image on the basis of the mesh. The image processing device preforms image blending on the basis of the input image, the transformed reference image, and mask data.

Abstract: The composition of the present invention induces changes in the composition of gut microbiota, particularly changes in the composition of Desulfovibrionasaceae strains, in a high glucose diet environment, so it has no toxicity to the body and has excellent brain tumor inhibitory activity, and thus it can effectively prevent, improve or treat brain tumors. Furthermore, such changes in the composition of gut microbiota in a high glucose diet environment induces a synergistic effect with anticancer drugs, particularly immune checkpoint inhibitors, and thus it can ultimately contribute to improving the survival rate of brain tumor patients.
