Existing tetrahedral meshing which require watertight and intersection free triangular mesh as input can be enhanced to tolerate and respect self-intersecting boundaries. After an initial tetrahedral mesh constructed with all input nodes, intersecting faces can be recovered using the proposed method. Starting from one of the intersecting faces, a set of intersecting faces around it can be detected, and a surrounding region can be sculpted out to form a void. Two intersection-free and topologically separate cavities can then be defined within the void and meshed independently. After stitching the meshes from the two cavities back to the original initial mesh, the existing tetrahedral meshing can continue with the regular meshing steps such as refinement etc. to finish tetrahedral meshing. In one special case when we have two points at the same location, in order to insert the second of the two points, a method can offset the second point inwardly into the mesh region a small little bit and then revert back the second point to its original location after meshing is done. The user input is not altered or mesh quality would not be affected because the point movement is small.

A graphics processing system performs hidden surface removal and texturing/shading on fragments of primitives. The system includes a primary depth buffer (PDB) for storing depth values of resolved fragments, and a secondary depth buffer (SDB) for storing depth values of unresolved fragments. Incoming fragments are depth tested against depth values from either the PDB or the SDB. When a fragment passes a depth test, its depth value is stored in the PDB if it is a resolved fragment (e.g. if it is opaque or translucent), and its depth value is stored in the SDB if it is an unresolved fragment (e.g. if it is a punch through fragment). This provides more opportunities for subsequent opaque objects to overwrite punch through fragments which passed a depth test, thereby reducing unnecessary processing and time which may be spent on fragments which ultimately will not contribute to the final rendered image.

In an embodiment, a DBMS receives a request to execute an operation on its managed database. The request may include an object identifier and a version identifier for a version of a database object, which is required for the successful execution of the operation on the database.

The method includes acquiring material blanks that are made of 7xxx series aluminum alloy, heating the blanks to a solvus temperature of the material, and stamping and quenching the heated blanks to form multiple parts. The parts are cooled to a second temperature lower than the solvus temperature during the quenching operation. The method further includes performing one or more structural modifications of the parts within a set time period that is less than or equal to 24 hours. The method further includes racking the parts with a gap defined between two adjacent parts, artificially aging the parts with an industrial oven, and pretreating the parts with a chemical solution.

Nucleic acid memory strands encoding digital data using a sequence of homopolymer tracts of repeated nucleotides provides a cheaper and faster alternative to conventional digital DNA storage techniques. The use of homopolymer tracts allows for lower fidelity, high throughput sequencing techniques such as nanopore sequencing to read data encoded in the memory strands. Specialized synthesis techniques allow for synthesis of long memory strands capable of encoding large volumes of data despite the reduced data density afforded by homopolymer tracts as compared to conventional single nucleotide sequences.

A method for displaying proteins and peptides is disclosed in which individual proteins or peptides remain associated with the DNA encoding them. Proteins or peptides can be generated by in vitro translation of DNA templates, either free in solution or arrayed on a solid support, such that the proteins or peptides remain immobilized on their DNA templates. In particular, high throughput sequencing can be combined with high throughput functional characterization of encoded proteins and peptides, wherein the identity of each protein or peptide is determined by DNA sequencing, and functional studies are carried out directly on each protein or peptide while immobilized on the DNA template encoding it. The methods of the invention should find numerous applications, for example, in high throughput genetic or pharmacological screening, epitope mapping, and protein engineering and directed evolution.

Efficient stem cell delivery into biomaterials using capillary driven encapsulation are disclosed herein where stem/progenitor and/or tissue specific cells are rapidly and efficiently seeded via capillary driven encapsulation into a porous scaffold for cell delivery in the skin or any other organ. The rapid capillary force approach maximizes both seeding time and efficiency by combining hydrophobic, entropic and capillary forces to promote active, ‘bottom-up’ cell engraftment. This methodology uses micro domain patterned biopolymers in a porous dry gel to generate capillary pressure to move a viscous stem cell mix from a hydrophobic reservoir into the polymer matrix to promote active cell seeding within the entire gel volume.
