Abstract: An antistatic pressure sensitive adhesive composition, useful in electronic and optical display applications, comprising an antistatic agent and a first block copolymer comprising at least two hard A block polymeric units each independently having a Tg of at least 50° C., and at least one soft B block (meth)acrylic polymeric unit having a Tg no greater than 20° C. The composition can comprise a second block copolymer. Articles comprising an antistatic pressure sensitive adhesive composition adjacent a first surface of a substrate.

Abstract: Embodiments described herein relate to training, by a computing system, a gamma mixture hurdle model. The model may characterize a functional relationship between: output data specifying food flows between zones, and input variables representing food production and food consumption in the zones. The training involves: (i) using binary logistic regression to estimate whether corresponding food flows exist between zone pairs, and (ii) for pairs in which corresponding food flows exist, using a gamma mixture model to estimate amounts of the corresponding food flows. Based on the gamma mixture hurdle model, the computing system can estimate, where each zone includes a respective set of regions: (i) whether corresponding food sub-flows exist between region pairs, and (ii) for pairs in which the corresponding food sub-flows are estimated to exist, potentials of the corresponding food sub-flows. The computing system can also determine, using a linear programming framework, values for the corresponding food sub-flows.

Abstract: Technologies are generally described for techniques useful in an interferometer system. In some examples, a system may include a first waveguide effective to propagate a first wave in a first mode. In some examples, the system may include a second waveguide effective to, in response to the first wave, propagate second and third waves in second and third modes, respectively. In some examples, the second waveguide may be effective to reflect the second and third waves off a reflection surface to produce first, second, third and fourth reflected waves. In some examples, the second waveguide may be effective to propagate the first and third reflected waves in the second mode and propagate the second and fourth reflected waves in the third mode.
