Abstract: A system and method for performing digital calibration of non-linearity in a circuit is presented. The circuit includes a phase detector, a statistics gathering device, and a feedback device. The phase detector provides information regarding a relationship between a clock from the programmable clock phase circuit and a reference signal. The statistics gathering device is coupled to the phase detector. The statistics gathering device receives an output of the phase detector to measure linearity of the programmable clock phase circuit. The feedback device is coupled to the statistics gathering device. The feedback device controls a delay and adjusts a phase of the clock based on measured values received from the statistics gathering device.

Abstract: Detection of an exploit including shellcode is disclosed. Memory blocks are monitored during dynamic analysis of a sample to identify a memory block including suspicious shellcode. The memory block is dumped in memory to identify a candidate shellcode entry point associated with the suspicious shellcode. The suspicious shellcode is executed based on the candidate shellcode entry point to determine whether the suspicious shellcode is malicious. A verdict is generated regarding the sample based on results of executing the suspicious shellcode.

Abstract: Commit time logging is performed as part of implementing time-based Multi-Version Concurrency Control (MVCC). A query engine may determine a commit time for a database transaction is committed to a database by applying MVCC to select different versions of data in the database according to transaction commit times. The query engine may store the commit time for the database transaction in a log structure stored in a non-volatile data store. A segment describing the log structure maintained in a volatile memory maintained in a volatile memory may be updated to include the commit time for the database transaction.

Abstract: This invention pertains to the field of plant extraction and separation technology, and provides a polysaccharide compound with a defined molecular structure that possesses antitumor efficacy. The polysaccharide compound is intended for the treatment of advanced cancer patients (those who are no longer candidates for surgery, have a life expectancy of only three to six months, and are still eligible for chemotherapy). The molecular formula is: (C30H50O25)n. The active ingredient, polysaccharide, is obtained through the extraction of effective components from Ganoderma lucidum under high temperature and high pressure. The polysaccharide with this active ingredient, characterized by its water solubility, is readily absorbed by the human body, offers antitumor effects, and has proven efficacy in the prevention of tumor development in humans.
