Abstract: Production of HFO-1132 and, in particular, HFO-1132E, may be produced from 1,1,2-trichloro-1,2,2-trifluoroethane (CFC-113). In a first step, 1,1,2-trifluoroethane (HFC-143) is produced by hydrogenating 1,1,2-trichloro-1,2,2-trifluoroethane (CFC-113) by reaction with hydrogen in the presence of a catalyst to produce 1,1,2-trifluoroethane (HFC-143). The 1,1,2-trifluoroethane (HFC-143) may then be dehydrofluorinated in the presence of a catalyst to produce trans-1,2-difluoroethylene (HFO-1132E) and/or cis-1,2-difluoroethylene (HFO-1132Z). The cis-1,2-difluoroethylene (HFO-1132Z) may then be isomerized to produce trans-1,2-difluoroethylene (HFO-1132E).

Abstract: Techniques and mechanisms for determining the pruning of one or more channels from a convolutional neural network (CNN) based on a gradient descent analysis of a performance loss. In an embodiment, a mask layer selectively masks one or more channels which communicate data between layers of the CNN. The CNN provides an output, and calculations are performed to determine a relationship between the masking and a loss of the CNN. The various masking of different channels is based on respective random variables and on probability values each corresponding to a different respective channel In another embodiment, the masking is further based on a continuous mask function which approximates a binary step function.

Abstract: Various embodiments are generally directed to techniques to tune a scale parameter for activations in binary neural networks, such as based on estimating a gradient for the scale parameter using quantization error, for instance. Some embodiments are particularly directed to tuning the scale parameter for activations by estimating the gradient for the scale parameter using a first “force” based on quantization error and a second, opposing, “force” based on clipping error. For instance, the first “force” based on the quantization error may give a gradient for the scale parameter that pushes the scale parameter lower to reduce the quantization error and the second “force” based on the clipping error may give a gradient for the scale parameter that moves the scale parameter higher to reduce the number of activations that are higher than a current scale parameter.

Abstract: A poly(arylene ether) copolymer is the product of oxidative copolymerization of monomers including a monohydric phenol and a dihydric phenol. It has an intrinsic viscosity of about 0.04 to about 0.15 deciliter per gram and, on average, about 1.8 to about 2 hydroxyl groups per molecule. The poly(arylene ether) copolymer is enriched in low molecular weight copolymer chains and copolymer chains that include a terminal unit derived from the dihydric phenol.

Abstract: Capped poly(arylene ether)s are prepared by a method that includes reacting a poly(arylene ether) with a capping agent to form a capping reaction mixture, washing the capping reaction mixture with a concentrated basic aqueous solution, and isolating the capped poly(arylene ether) by a total isolation method. The washing method is effective for removal of capping-related impurities, and surprisingly does not result in decomposition of the capped poly(arylene ether).
