    Abstract: A method for channel equalization of received data includes steps of: receiving the received data in a received data packet; calculating filter setting coefficients for an input filter and calculating equalizer setting coefficients for an equalizer; setting the input filter using the filter setting coefficients and setting the equalizer using the equalizer setting coefficients; equalizing the received data using the input filter and using the equalizer; determining channel parameters for the transmission channel from the received data Xk; storing the channel parameters in a data field; and performing the step of calculating the filter setting coefficients for the input filter and calculating the equalizer setting coefficients for the equalizer by performing a GIVENS rotation of the data field.

    Abstract: The present invention relates to the field of bioengineering. It provides a Candida antarctica lipase B mutant and its application. The mutant enzyme overcomes the limit of the parent enzyme that can exhibit high enantioselectivity towards (R)-3-TBDMSO glutaric acid methyl monoester only at temperatures below 5° C. The mutant enzyme successfully increased R-ee value at 5-70° C. The mutant D223V/A281S exhibits high R-ee value (>99%), high conversion rate (80%), and high space-time yield (107.54 g L−1 d−1). The present invention lays a foundation for industrial production of (R)-3-TBDMSO glutaric acid methyl monoester using a biosynthesis approach and provide insights into conformational dynamics-based enzyme design.

    Abstract: A fabrication method for a semiconductor device structure is provided. The device structure has a layer of silicon and a layer of silicon dioxide overlying the layer of silicon, and the method begins by forming an isolation recess by removing a portion of the silicon dioxide and a portion of the silicon. The isolation recess is filled with stress-inducing silicon nitride and, thereafter, the silicon dioxide is removed such that the stress-inducing silicon nitride protrudes above the silicon. Next, the exposed silicon is thermally oxidized to form silicon dioxide hardmask material overlying the silicon. Thereafter, a first portion of the silicon dioxide hardmask material is removed to reveal an accessible surface of the silicon, while leaving a second portion of the silicon dioxide hardmask material intact. Next, silicon germanium is epitaxially grown from the accessible surface of the silicon.
