Abstract: A system comprising a causal convolutional neural network to autoregressively generate a succession of values of a data item conditioned upon previously generated values of the data item. The system includes support memory for a set of support data patches each of which comprises an encoding of an example data item. A soft attention mechanism attends to one or more patches when generating the current item value. The soft attention mechanism determines a set of scores for the support data patches, for example in the form of a soft attention query vector dependent upon the previously generated values of the data item. The soft attention query vector is used to query the memory. When generating the value of the data item at a current iteration layers of the causal convolutional neural network are conditioned upon the support data patches weighted by the scores.

Abstract: Disclosed herein is a photosensitive composition comprising an epoxy resin, a photoacid generator, and an antioxidant. The disclosed composition is useful for producing relief images having reduced yellowing or other discoloration due to thermal oxidation.

Abstract: Disclosed herein is a photosensitive composition that includes: a novolak polymer; one or more crosslinkers; photoacid generator; and a hydroxybenzophenone compound having the general structure (I) wherein m is 0 to 3 and n is 0 to 4 and m+n may be 0 to 5

Abstract: The present invention provides for photoluminescent optical fibers that are used to illuminate sighting reticles. The fibers are activated by electromagnetic radiation and emit electromagnetic radiation of various wavelengths at high intensity and for long periods of time. The emission from the photoluminescent fiber can only be seen coming from one terminal end of the fiber, which is designed to be positioned inside the sighting device to illuminate a reticle. The photoluminescent fiber contains a base optical fiber which is covered at least in part by a photoluminescent composition which itself is fully covered by a second composition that allows the activating electromagnetic radiation to pass through to activate the photoluminescent layer while preventing the emissive electromagnetic radiation of the photoluminescent layer from passing back through.

Abstract: An image-receiving element for use in photographic and photothermographic diffusion transfer film units of the type where the image-receiving element is designed to be removed, or “peeled-apart” from a photosensitive element following exposure and photographic processing. The present image-receiving element comprises, in sequence, a support, an image-receiving layer and a strip-coat layer which serves to facilitate separation of the image-receiving element from the photosensitive element after photographic processing. The strip-coat layer comprises an anion of poly(acrylic acid), or a salt thereof, complexed with a cationic quaternary salt. In a preferred embodiment, the strip coat layer may include an ethoxylated alcohol.

Abstract: There is described a novel diffusion transfer photographic system wherein an exposed diffusion transfer photographic film unit is developed with an aqueous alkaline processing composition in the presence of alumina-free titanium dioxide.

Abstract: There are described novel photographic processing compositions, film units and processes for use in diffusion transfer photographic systems. More particularly, there is described a method for forming a diffusion transfer image photographic processing of diffusion transfer photographic film units in the presence of hypoxanthine and inosine. Diffusion transfer photographic systems utilizing the novel photographic element or method of the present invention exhibit substantially fewer, if any, crystals on the final image of the finished photograph post-processing.
