摘要： Methods of forming a hierarchical porous monolith are provided. The methods include mixing a monomer, a silica precursor and a catalyst in a solvent to form a mixture. The methods also include adding a gelling agent to the mixture to form a polymer-silica composite gel. The polymer-silica composite gel undergoes a phase separation to separate from the solvent and the unreacted silica precursor. The method further includes drying the polymer-silica composite gel to evaporate the solvent to form a polymer-silica monolith and processing the polymer-silica monolith to form at least one of a polymer monolith, a carbon monolith, a silica monolith and a carbon-silica monolith.

摘要： Drive signals for a display device may be generated using Separable Non-negative Matrix Series Representation (SNMSR) of source image data and applying a nonnegative matrix factorization (NNMF) process to source image data to generate approximation image data (Ii), partial sum image data (Pi) and residue image data (Ji). Iteratively, NNMF may be applied to Ji such that subsequent Ii and Ji may be generated, where each Ii can be associated with a corresponding sub-frame image. At each iteration, the Ii may be sent to the display buffer for selective activation of multiple row and column drivers during a single sub-frame interval. At each iteration, a determination may be made if a predetermined criterion is satisfied. The iterations may be terminated and the series truncated when the predetermined criterion is satisfied. Integration of the sub-frame images displayed over a complete frame interval by human eye effectively corresponds to the source image.

摘要： Techniques related to miniature lenses and lens arrays are generally described herein. The described techniques may be embodied in apparatuses, systems, methods and/or processes for making and using such lenses. In some examples, the various techniques may be utilized for miniature lenses such as nanometer to micron sized spherical lenses or lens arrays. An example process may include dewetting polymer films to form such lenses. The resulting lens-size may be tunable from about 200 nm to a few tens of microns, and more particularly in a range from about 200 nm to about 10 μm with spherical shapes of contact angles ranging from about 30° to about 150°. The resulting lenses may be tunable polymeric structures formed generally by self-organized room temperature dewetting of ultrathin polymer films by reducing the surface tension.

摘要： Embodiments of the present disclosure set forth methods for selecting a preferred data set from distributed databases including a first database having a first probability attribute and a second database having a second probability attribute. One example method may include receiving a first data set from the first database and a second data set from the second database. The first data set includes a first monotonic attribute. The second data set includes a second monotonic attribute. It may further include selecting a candidate data set from one of the first data set and the second data set based on a comparison of the first monotonic attribute and the second monotonic attribute and determining whether the selected candidate data set is the preferred data set.
