Abstract: Large volume cellular material may be preserved by combining the cellular material with a cryoprotectant formulation/medium/solution containing at least one mNP and then subjecting the cellular material to a vitrification preservation protocol including nanowarming. This preservation method is particularly effective for cartilage tissues.

Abstract: A baseband process is provided for operating on a receiver in a communication system, such as an 802.15.4 communication system in the 868/915 MHz band In one aspect, the baseband process is useful for decoding a baseband signal, and in another aspect is useful for determining a clear channel assessment. In decoding the baseband signal, the process digitizes the baseband signal into sample sets according to a symbol period. The sample sets may be, for example, from sequential symbols having a known symbol value, such as from the preamble portion of a data frame. Since the symbol values are already known, the process may determine a reference value by correlating two or more known sample sets. To decode a sample set having an unknown code symbol, the process determines a correlation value by correlating that unknown sample set to a sample set having a known code symbol, which is typically the adjacent and preceding sample set.

Abstract: The baseband receiver provides a baseband process operating on a receiver in a communication system, such as an 802.15.4 communication system. The baseband process digitizes a baseband signal, and uses less than the full resolution of the digitized data to perform an automatic gain control. In another aspect of the baseband receiver a data frame is detected using less than the full resolution of the digitized data, and without the need for prior synchronization. After a frame is detected, the baseband signal is correlated with reference signals from a set of predefined reference signals, and the reference signal with the best correlation is identified. By identifying the best correlating reference signal, the baseband process is able to identify a characteristic of the baseband signal.
