High-yielding method for chemical hydrolysis of lignocellulose into monosaccharides. The process of the invention can additionally be applied to cellulose, xylan and related biomass polysaccharides, such as galactan, mannan, or arabinan. The method is employed for hydrolysis of a biomass polysaccharide substrate. The process is carried out in an ionic liquid in which cellulose is soluble in the presence of catalytic acid at a temperature sufficiently high to initiate hydrolysis. Water is added to the reaction mixture after initiation of hydrolysis at a rate controlled to avoid precipitation yet avoid undesired sugar dehydration products such ad HMF. Hydrolysis product is useful as feedstock for fermentations including fermentation processes for ethanol, butanol and other fuels.

A photovoltaic cell exhibiting an overall conversion efficiency of at least 9.0% is prepared from a copper-indium-gallium-diselenide thin film.

The present invention is directed to a low cost shieldable safety needle assembly. The assembly includes a needle cannula and a tip guard axially movable along the needle cannula through a drive mechanism. The drive mechanism may be interconnected between the tip guard and the needle cannula through a hub. The tip guard is axially movable along the needle cannula from a proximal position substantially adjacent a proximal end of the needle cannula at the hub, to a distal position in which the tip guard protectively surrounds the distal end of the needle cannula, thus effectively shielding the puncture tip of the needle. The drive mechanism is a unitary structure which is capable of maintaining a first self-supporting shape for maintaining the tip guard in the proximal position and is deflectable from the first self-supporting shape to a second extended shape in which the tip guard is moved to the distal position. The drive mechanism may be a rigid flexible planar sheet material which includes a plurality of folds for defining the self-supporting shape. The needle assembly may include structure for mating with a hypodermic syringe, a blood collection set, or other medical device.

A Soft Computing (SC) optimizer for designing a Knowledge Base (KB) to be used in a control system for controlling a suspension system is described. The SC optimizer includes a fuzzy inference engine based on a Fuzzy Neural Network (FNN). The SC Optimizer provides Fuzzy Inference System (FIS) structure selection, FIS structure optimization method selection, and teaching signal selection and generation. The user selects a fuzzy model, including one or more of: the number of input and/or output variables; the type of fuzzy inference model (e.g., Mamdani, Sugeno, Tsukamoto, etc.); and the preliminary type of membership functions. A Genetic Algorithm (GA) is used to optimize linguistic variable parameters and the input-output training patterns. A GA is also used to optimize the rule base, using the fuzzy model, optimal linguistic variable parameters, and a teaching signal. The GA produces a near-optimal FNN. The near-optimal FNN can be improved using classical derivative-based optimization procedures. The FIS structure found by the GA is optimized with a fitness function based on a response of the actual suspension system model of the controlled suspension system. The SC optimizer produces a robust KB that is typically smaller that the KB produced by prior art methods.
