    Abstract: A synchronous circuit for clock multiplexing and output-enable is implemented using a pair of logic gates and an output block. Select signals and enable signals with the corresponding logic sense are provided as inputs to the pair of logic gates, which generate respective logic outputs. The output block contains synchronizers clocked by respective input signals, and receives the logic outputs also as inputs. The output block provides a selected one of the input signals as an output, the provision of the selected input signal being accomplished in a synchronous fashion. Enabling and disabling of the output are also performed synchronously.

    Abstract: The present disclosure provides systems and methods for handling performance monitoring (PM) data in a database in a manner that supports different PM data sets from different network element (NE) device types in an integrated manner. The present invention defines a single database structure that can be utilized to store, handle, retrieve, etc. PM counters from multiple NEs including NEs of different types, e.g. SONET/SDH NE, DWDM NE, optical switch, Ethernet switch, etc. The single database enables an efficient mechanism to handle PM data in a uniform way across a network with different device types.

    Abstract: A method (100) for detecting mycotoxins in organic material, wherein the method (100) comprises of: storing about 2-5 grams of organic material in a temperature less than room temperature; adding a solvent Acetonitrile in the stored organic material to form a first mixture, wherein the first mixture is transferred to a 40-60 ml tubes, centrifuged and shaken for a defined interval; adding 0.5-3 ml of supernatant, 80-120 mg of cyclo-18-carbon (C18) and 200-400 mg of Magnesium sulfate to the first mixture to form a second mixture; and filtering the formed second mixture using a filter syringe to obtain a filtrate, wherein the mycotoxins are detected from the obtained filtrate using Ultra High-Performance Liquid Chromatography (UHPLC) coupled with a mass spectrometer.

    Abstract: Methods for retiming and realigning SONET signals include demultiplexing STS-1 signals from an STS-3 signal, buffering each of the three signals in a FIFO, determining the FIFO depth over time, determining a pointer leak rate based in part on FIFO depth and also based on the rate of received pointer movements. For a 28-byte deep FIFO, if the depth of a FIFO is 12-16 bytes, no pointer leaking is performed. If the depth is 0-4 bytes, an immediate positive leak is performed. If the depth is 24-28, an immediate negative leak is performed. If the depth is 5-11 bytes a calculated positive leak is performed. If the depth is 17-23 bytes, a calculated negative leak is performed. The calculated leak rates are based on the net number of pointer movements (magnitude of positive and negative movements summed) received every 32 seconds (256,000 frames).
