Abstract: A scaffold assembly and related methods of manufacturing and/or using the scaffold for stem cell culture and tissue engineering applications are disclosed which at least partially mimic a native biological environment by providing biochemical, topographical, mechanical and electrical cues by using an electroactive material. The assembly includes at least one layer of substantially aligned, electrospun polymer fiber having an operative connection for individual voltage application. A method of cell tissue engineering and/or stem cell differentiation uses the assembly seeded with a sample of cells suspended in cell culture media, incubates and applies voltage to one or more layers, and thus produces cells and/or a tissue construct.

Abstract: An electroactive material comprises multiple layers of electroactive composite with each layer having unique dielectric, electrical and mechanical properties that define an electromechanical operation thereof when affected by an external stimulus. For example, each layer can be (i) a 2-phase composite made from a polymer with polarizable moieties and an effective amount of carbon nanotubes incorporated in the polymer for a predetermined electomechanical operation, or (ii) a 3-phase composite having the elements of the 2-phase composite and further including a third component of micro-sized to nano-sized particles of an electroactive ceramic incorporated in the polymer matrix.

Abstract: An electroactive sensing or actuating material comprises a composite made from a polymer with polarizable moieties and an effective amount of carbon nanotubes incorporated in the polymer for a predetermined electromechanical operation of the composite when such composite is affected by an external stimulus. In another embodiment, the composite comprises a third component of micro-sized to nano-sized particles of an electroactive ceramic that is also incorporated in the polymer matrix. The method for making the three-phase composite comprises either incorporating the carbon nanotubes in the polymer matrix before incorporation of the particles of ceramic or mixing the carbon nanotubes and particles of ceramic together in a solution before incorporation in the polymer matrix.

Abstract: A method and system are provided for aligning fibers in an electrospinning process. A jet of a fiberizable material is directed towards an uncharged collector from a dispensing location that is spaced apart from the collector. While the fiberizable material is directed towards the collector, an elliptical electric field is generated via the electrically charged dispenser and an oppositely-charged control location. The field spans between the dispensing location and the control location that is within line-of-sight of the dispensing location, and impinges upon at least a portion of the collector. Various combinations of numbers and geometries of dispensers, collectors, and electrodes can be used.

Abstract: Using a bounding language to control or restrict the changes that can be made to contents of a structured document (e.g., a document encoded in the Extensible Markup Language, or “XML”), and also the bounding language and documents encoded according to the bounding language. A Document Type Definition (“DTD”) is defined as a “bounding DTD”, and one or more structured documents containing editing restrictions are defined according to this DTD. A processing component uses a structured document containing editing restrictions as input, and programmatically determines which fields of another structured document can be edited, which fields should be hidden, and so forth. By restricting the parts of the file that can be edited, users who need to do the editing are shielded from irrelevant details, and can carry out their task with less risk of making errors (and without needing to understand the details of the structured document markup language).

The invention is also directed to pharmaceutical compositions comprising these compounds and the use of these compounds and compositions in the treatment of such diseases in which the beta-secretase enzyme and HIV protease are involved.

Abstract: Methods, systems, computer program products, and methods of doing business by using a meta-editor to generate components (e.g., a specification of a rules language that restricts editing operations on structured documents, a specification of rules according to this language, and a graphical user interface editor that operates according to the specified rules) for use in controlling or restricting the changes that can be made to contents of a structured document (e.g., a document encoded in the Extensible Markup Language, or “XML”). A Document Type Definition (“DTD”) is generated as a “bounding DTD”, based on editing choices made using the meta editor, and one or more structured documents containing editing restrictions are generated according to this DTD and these editing choices. An editor (or editing component) is generated that programmatically determines which elements of another structured document can be edited, which elements should be hidden, and so forth.
