A technique is provided for causing a computer to perform calculation using a sum-product decoding method (belief propagation method) with respect to LDPC or turbo codes.

A job that can be divided into a selected number of tasks is provided to one computer of a plurality of computers connected via networks, and job tasks are processed with the one computer for predetermined time. A progress rate of task processing for the predetermined time is calculated, and completion time for task processing on the one computer is estimated on the basis of the progress rate and the predetermined time. It is determined whether the estimated completion time meets requirements of the job. When the estimated completion time meets the requirements, job tasks are processed with the one computer, and results are generated.

Abstract: Undifferentiated primordial stem cells are manipulated to permit their long term growth in defined media lacking serum and feeder layer cells by shifting the apoptotic balance of the cells, through increasing the activity of Bcl-2 family anti-apoptotic proteins or decreasing the activity of Bcl-2 family pro-apoptotic proteins. In some embodiments of the invention, the Bcl family protein is Bcl-2. The ES cells sustain the characteristics of undifferentiated, pluripotent stem cells during long-term serum- and feeder layer cell-free conditions, including the ability to be expanded in vitro, but maintain their potential to differentiate into mature cell types.

Abstract: A method for analyzing performance of an information processing system having information processing apparatuses providing services to each other. Communication packets sent or received between the apparatuses are acquired. The apparatuses receive calls from other apparatuses for providing services indicated in the packets. A service call count aji of the calls received by the apparatuses during period j of m periods for the service i of n services is computed. A busy time bj is computed by summing processing times by the apparatuses for performing the services pertaining to the calls received by the apparatuses during period j. An average processing time di is computed by the apparatuses for each service i, as is an error ?j in di wherein ?j=bj??iajidi, by minimizing an index indicative of ?j. The average processing time di is stored in a storage device and/or displayed on a display device.
