Abstract: Encoding a file into a plurality of chunks, wherein a subset of the plurality of chunks may be used to create a functional equivalent of the file. At least one additional chunk is created from the plurality of chunks. The at least one additional chunk is directed to be stored in a cache memory and the plurality of chunks are directed to be stored on at least one storage node. Upon demand for the file, at least one additional chunk is cased to be retrieved from the cache and at least a portion of the plurality of chunks are caused to be retrieved from the at least one storage node and the functional equivalent of the file is constructed through utilization of the at least one additional chunk and the portion of the plurality of chunks.

Abstract: This disclosure presents the use of electrons as the ‘working fluid’ in conjunction with a solid nanomaterial that hinders electron coupling to the atomic lattice of the nanomaterial, i.e., they are out of equilibrium. The electrons can achieve very high effective temperatures with minimal heating of the solid lattice. These ‘hot’ electrons emit from the absorbing material, carrying both the light energy and energy acquired from the atomic lattice. Thus, the operation of this disclosure includes shining light on an object to make the object cool instead of heat. It is envisioned that one of ordinary skill in the art would find the operation quite counter-intuitive.

Abstract: This invention discloses a method for controlling nanoscopic wetting near or at a molecular scale for synthetic material applications. In particular this invention relates to a method for preparing a monolayer or thin film with a patterned nanoscopic wetting surface using a ‘sitting’ phase of polymerizable amphiphile, wherein hydrophobic alkyl chains of the amphiphile extend along the supporting surface and the amphiphile molecules align side-to-side, effectively forming a repeating cross-section of bilayer with alternating hydrophilic and hydrophobic stripes of a ˜6 nm pitch tunable based on the chain length of the amphiphile. Products prepared according to the methods disclosed herein are within the scope of this invention. In some embodiments, monolayers or thin films so prepared are transferable.

Abstract: Certain examples described herein relate to the halftoning of a color image. In one example, a set of clusters are determined based on the color image. A set of edges are also detected in the color images. Clusters within these edges are then merged. A set of screens for halftoning are assigned to the set of clusters. This assignment is based on color property metrics for the set of clusters. The color image is halftoned using the set of screens assigned to the merged clusters.
