Abstract: A system includes a gain module, an optical module, and a feedback module. The gain module processes a first portion of an electrical signal to generate a first compensated portion of the electrical signal, the first portion of the electrical signal having a first frequency range. The optical module generates an optical signal based on a combination of the first compensated portion of the electrical signal and a second portion of the electrical signal having a second frequency range that is higher than the first frequency range. The feedback module provides, to the gain module, an electrical feedback signal based at least in part on a signal strength of the optical signal. The gain module updates the first compensated portion of the electrical signal based on the electrical feedback signal.

Abstract: The invention provides genetically engineered microorganisms and methods for the biological production of ethylene glycol and precursors of ethylene glycol. In particular, the microorganism of the invention produces ethylene glycol or a precursor of ethylene glycol through one or more of 5,10-methylenetetrahydrofolate, oxaloacetate, citrate, malate, and glycine. The invention further provides compositions comprising ethylene glycol or polymers of ethylene glycol such as polyethylene terephthalate.

Abstract: The invention provides genetically engineered microorganisms and methods for the production of a product by a two-step fermentation process. In particular, the present invention relates to production of an intermediate by microbial fermentation of a gaseous substrate followed by conversion of the intermediate to a final product through microbial fermentation of a carbohydrate substrate.

Abstract: Various systems and methods for implementing additional security in a flashless modem are described herein. A modem system for implementing additional security in a flashless modem, the modem system comprising: local storage; non-volatile random access memory (NVRAM); and an access control module to: read non-volatile memory data (NVM data) from the local storage; calculate a hash of the NVM data; access a previously-stored hash; compare the hash of the NVM data with the previously-stored hash to produce a comparison; and control access to the NVM data based on the comparison.

Abstract: A rotor for a wind turbine, having a diameter of 50 metres or more, has a blade with at least two blade sections in the lengthwise direction of the blade, where at least one blade section has a curvature along the blade and relative to a second blade section, where said curvature results in the tip end of said blade being offset (x) relative to the axis of the blade root. A ratio (x/L) of the offset (x) relative to a distance (L) from the tip end of the blade to the blade root is between 0 and 0.1.

Abstract: The present invention is directed to a proteorhodopsin mutant having improved optical characteristics. One improved optical characteristic is having a lower pH (pKrh) at which equal concentrations of the acidic and basic spectral form of the proteorhodopsin molecules are present. Another improved optical characteristic is having a smaller difference in maximum absorption wavelength between the basic and the acidic form. The mutant comprises a mutation in a conserved amino acid residue of a proteorhodopsin variant, which causes spectral shifts. A preferred mutation site is a conserved histidine residue at amino acid position 75 of Bac31A8, or position 77 of Hot75m1, or its equivalent position of a proteorhodopsin variant. Another preferred mutation site is a conserved arginine residue at amino acid position 94 of Bac31A8, or position 96 of Hot75m1, or its equivalent position of a proteorhodopsin variant.
