  • Publication number: 20240111833
    Abstract: A storing unit stores, amongst coefficients, values of a coefficient group associated with one selected from multiple variable groups, which are obtained by dividing state variables of an evaluation function. A searching unit searches for a solution to an optimization problem by repeating update processing, which includes calculating, using the values of the coefficient group, a value change of the evaluation function responsive to changing the value of each state variable of the variable group and changing the value of one state variable thereof based on the value change and temperature. A processing unit calculates multiplicity indicating the iteration count in which the values of the variable group are maintained in a search using Markov chain Monte Carlo (MCMC), and causes, responsive to cumulated multiplicity exceeding a threshold, the searching unit to perform the update processing using the values of the coefficient group associated with a different variable group.

  • Publication number: 20230350972
    Abstract: A storage unit stores some of a plurality of coupling coefficients stored in a storage device. A processing unit takes a plurality of first state variables among a plurality of state variables as a trial target set. The processing unit performs a process of reading a plurality of first coupling coefficients corresponding to a plurality of first pairs of the first state variables belonging to the trial target set from the storage device, storing the plurality of first coupling coefficients in the storage unit, and conducting, a plurality of times, a trial on whether to update the value of any first state variable belonging to the trial target set using the plurality of first coupling coefficients. The processing unit repeats change of the trial target set and the process, so as to target all the plurality of state variables in the trials.

  • Patent number: 11596716
    Abstract: Compositions of small molecules, matrices, and isolated cells including methods of preparation, and methods for differentiation, trans-differentiation, and proliferation of animal cells into the osteoblast cell lineage were described. Examples of osteogenic materials that were administered to cells or co-cultured with cells are represented by compounds of Formula II, IV, and VI independently or preferably in combination with a matrix to afford bone cells. Small molecule-stimulated cells were also combined with a matrix, placed with a cellular adhesive or material carrier and implanted to a site in an animal for bone repair. Matrix pretreated with compounds of Formula II, IV, and VI were also used to cause cells to migrate to the matrix that is of use for therapeutic purposes.

  • Publication number: 20220056093
    Abstract: The present invention provides methods for targeting interleukin-2 receptor-expressing cells, and, in particular, inhibiting the growth of such cells by using an interleukin-2 (IL-2) variant conjugated to a biologically active molecule that will affect cells expressing the interleukin-2 receptor.
