A laminar structure upon a substrate is formed from a) a lattice layer comprising DNA (deoxyribonucleic acid) segments arranged to form cells of the lattice layer, and b), at least one nanoparticle being disposed within each cell of the lattice layer. The nanoparticles are preferably of substantially uniform diameter not exceeding 50 nanometers. A coating may be applied to adhere the the particles to the substrate and to maintain their substantially uniform spaced-apart relationship. The DNA lat...

Methods and systems for quantization and data embedding are described. In at least some embodiments, a transform is applied on an image that is to be watermarked and statistics associated with the image are computed. The computed statistics are quantized using a symmetric lattice, and a watermark is computed using the lattice quantized statistics. The watermark is then inserted into the image.

A coating composition containing an emulsion polymer prepared with up to about 20% by weight, based on total polymerizable monomers, of addition polymerizable esters of the glycidyl esters of tertiary acids having 9 or more carbon atoms, preferably up to 18 carbon atoms, and particularly having 9 to 11 carbon atoms has improved application properties and produces coatings with better appearance and less water sensitivity. The emulsion polymerization process of the invention produces less coagulu...

An assembly of prefabricated structural components for lattices or trusses includes a plurality of rod-like, load-bearing elements, a plurality of joining elements for joining the rod-like elements to one another, a plurality of connecting elements for connecting the rod-like elements to the joining elements, and a plurality of clamping elements for clamping the connecting elements and associated rod-like elements to the joining elements.

Water-insoluble, noncrosslinking, nonporous copolymers are provided which have recurring units derived from: (a) from 0 to about 99.9 mole percent of one or more ethylenically unsaturated polymerizable oleophillic monomers which provide hydrophobicity to said copolymer, provided that none of said monomers are crosslinking monomers, (b) from about 0.1 to 100 mole percent of one or more ethylenically unsaturated polymerizable monomers having a succinimidoxycarbonyl group, and (c) from 0 to about 1...

A antenna array (20) includes a plurality of periodic or aperiodic arranged sub-arrays (22). Each sub-array (22) includes a plurality of antenna elements (32) arranged in the form of a spiral (30). The sub-arrays (22) can comprise various spiral shapes to provide the required physical configuration and operational parameters to the antenna array (20). The elements (32) of each sub-array (22) are arranged to minimize the number of such elements (32) that intersect imaginary planes perpendicular t...

A process for device fabrication is disclosed in which two substrates having different crystal lattices are bound together. In the process a layer of material that has a crystal lattice similar to the crystal lattices of the first substrate is formed on the surface of the second substrate. The thickness of the layer is about 1 nm to about 2 nm. The layer of material is then bound to the surface of the first substrate.

Systems and methods for determining word confidence scores. Speech recognition systems generate a word lattice for speech input. Posterior probabilities of the words in the word lattice are determined using a forward-backward algorithm. Next, time slots are defined for the word lattice, and for all transitions that at least partially overlap a particular time slot, the posterior probabilities of transitions that have the same word label are combined for those transitions. The combined posterior ...

A method of preparing polymer lattices of homogeneous interpenetrated structure, starting from a mixture of at least two basic prepolymer constituents is characterized by the fact that a microwave radiation is applied having a frequency spectrum chosen in order that it interacts preferentially with the first prepolymer and a power density chosen in order that it directly activates the exothermic reaction of cross-linking of the first prepolymer. The cross-linking of the second prepolymer is only...

This invention relates to the introduction of viable cells into a fibrous lattice by surgical, force-utilizing, or other manipulative techniques, all of which are referred to herein as "seeding." One embodiment comprises an autografting technique which involves intact tissue. Other embodiments which involve the distribution of an aqueous suspension of cells comprise centrifugal, spraying, pipetting and syringe emplacement. Each cell that survives the seeding process may reproduce into a colony o...
