Abstract: A control circuit for a multi-phase power conversion circuit and a multi-phase power supply are provided. The conversion circuit includes a plurality of switching circuits which have output terminals being coupled together to supply power to a load. The control circuit includes an error amplifier, a pulse width modulation circuit, and a multi-phase logic control circuit. The multi-phase logic control circuit generates a plurality of PWM signals according to an on time signal, which are delayed phase by phase and control on and off states of the plurality of switching circuits, and each of which has a pulse width being consistent with the on time signal. This reduces the circuit size and cost of the multi-phase power supply controller, and solves the problem of phase-to-phase current oscillation in a case that the switching circuits operate under duty ratios independent for various phases.

Abstract: A method, computer program product, and computer system for repairing a Dockerfile. Library versions containing initial version numbers of libraries are extracted from the Dockerfile. A Monte Carlo tree search (MCTS) is executed, using the extracted library versions as input, which generates a tree that includes multiple levels populated with noses. Each node in a level represents the generic library name of a library version in the Dockrerfile and an associated randomly selected version number. At least one of the randomly selected version numbers associated with at least one node in a level differs from the initial version number associated with a versionf. A best successful installation path is selected from the at least one successful installation path. The Dockerfile is repaired by inserting randomly selected version numbers into Dockerfile as replacements for some of the initial version numbers.

Abstract: A method of generating multipotent stem cells from adult human peripheral blood cells by isolating the peripheral blood insulin-producing cells and exposing them to adult peripheral blood-derived mitochondria. Adult peripheral blood insulin-producing cells (PB-IPC) are isolated from adult peripheral blood by adherence to a hydrophobic surface with a positive charge, such as a Petri dish. Once the PB-IPC are isolated, mitochondria derived from adult peripheral blood are applied to the isolated PB-IPC. The mitochondria are then taken in by the PB-IPC and enter the nuclei of the PB-IPC, allowing the cells to be reprogrammed, transforming PB-IPC into multipotent stem cells and giving rise to three germ layer-derived cells. Additionally, PB-IPC give rise to functional CD34+ hematopoietic stem cell (HSC)-like cells after treatment with adult peripheral blood-derived mitochondria.

Abstract: Systems and methods are provided for privacy-preserving image feature matching in computer vision applications, including receiving a raw image descriptor, and perturbing the raw image descriptor using a subset selection mechanism to generate a perturbed descriptor set that includes the raw image descriptor and additional descriptors. Each descriptor in the perturbed descriptor set is replaced with its nearest neighbor in a predefined descriptor database to reduce the output domain size of the subset selection mechanism. Local differential privacy (LDP) protocols are employed to further perturb the descriptor set, ensuring formal privacy guarantees, and the perturbed descriptor set is matched against a second set of descriptors for image feature matching.

Abstract: Embodiments of the present invention avoid the processing problems associated with using conventional computer systems for identifying and characterizing all of the substructures (e.g., metabolites) of large complex molecules by using a defined minimum cleavable unit (MCU) and an MCU graph for a chosen molecule, as well as a “cut vertex” in the MCU graph for the chosen molecule. The system splits the MCU graph of the chosen molecule at the specified cut vertex to produce two separate MCU graph components (i.e., a first MCU subgraph and a second MCU subgraph) of the chosen molecule, and generates and traverses a first line graph component and a second line graph component, respectively, for the two MCU subgraph components with a graph traversing algorithm to generate and store in memory a first database of substructures and molecular weights for the first component, and a second database of substructures and molecular weights for the second line graph component.
