Drugs, especially low aqueous solubility drugs, are provided in a porous matrix form, preferably microparticles, which enhances dissolution of the drug in aqueous media. The drug matrices preferably are made using a process that includes (i) dissolving a drug, preferably a drug having low aqueous solubility, in a volatile solvent to form a drug solution, (ii) combining at least one pore forming agent with the drug solution to form an emulsion, suspension, or second solution and hydrophilic or hydrophobic excipients that stabilize the drug and inhibit crystallization, and (iii) removing the volatile solvent and pore forming agent from the emulsion, suspension, or second solution to yield the porous matrix of drug. Hydrophobic or hydrophilic excipients may be selected to stabilize the drug in crystalline form by inhibiting crystal growth or to stabilize the drug in amorphous form by preventing crystallization. The pore forming agent can be either a volatile liquid that is immiscible with the drug solvent or a volatile solid-compound, preferably a volatile salt. In a preferred embodiment, spray drying is used to remove the solvents and the pore forming agent. The resulting porous matrix has a faster rate of dissolution following administration to a patient, as compared to non-porous matrix forms of the drug. In a preferred embodiment, microparticles of the porous drug matrix are reconstituted with an aqueous medium and administered parenterally, or processed using standard techniques into tablets or capsules for oral administration.

An implantable devices for the effective elimination of an arrhythmogenic site from the myocardium is presented. By inserting small biocompatible conductors and/or insulators into the heart tissue at the arrhythmogenic site, it is possible to effectively eliminate a portion of the tissue from the electric field and current paths within the heart. The device would act as an alternative to the standard techniques for the removal of tissue from the effective contribution to the hearts electrical action which require the destruction of tissue via energy transfer (RF, microwave, cryogenic, etc.). This device is a significant improvement in the state of the art in that it does not require tissue necrosis.In one preferred embodiment the device is a non conductive helix that is permanently implanted into the heart wall around the arrhythmogenic site. In variations on the embodiment, the structure is wholly or partially conductive, the structure is used as an implantable substrate for anti arrhythmic, inflammatory, or angiogenic pharmacological agents, and the structure is deliverable by a catheter with a disengaging stylet. In other preferred embodiments that may incorporate the same variations, the device is a straight or curved stake, or a group of such stakes that are inserted simultaneously.

Method, system and program product for migrating an integrated circuit (IC) layout for, for example, alternating aperture phase shift masks (AltPSM), are disclosed. In order to migrate a layout to phase compliance, jogs are identified on a first (AltPSM) layer and shifted to another second layer. Isolated or clustered jogs are shifted into an open channel portions on the second layer where possible. Remaining clustered jogs are shifted into as few new channels as possible on the second layer. The jog removal process leaves unidirectional wires that can be trivially phase colored. Standard technology migration techniques are then used to legalize the results on the layers.

Embodiments of the present invention provide services that enable individuals to rent and/or purchase content over the Internet and to receive it electronically, referred to below as “EZTakes.” This content may include movies, TV shows, music, games and other information typically distributed on CD/DVD. EZTakes leverages high-speed broadband Internet connections, peer-to-peer networking, digital rights management (DRM) and the growing prevalence of home computers that now typically feature large hard drives (e.g. 180+gigabytes) and have the capability to “burn” (i.e. create) DVDs and/or CDs. EZTakes bridges the gap between the home computer and the living room by using standard technologies that consumers already own and are already familiar with: home computers, DVD media, DVD players and the Internet. EZTakes also promotes the interests of content owners (e.g. movie production companies) by expanding their revenue opportunities through enabling them to distribute their content assets over the Internet. EZTakes also includes technical control mechanisms, such as digital watermarking, that could not easily be exploited when using physical DVD/CD distribution channels.

The present invention presents a number of improvements for managing erase processes in non-volatile memory. Such memory systems typically manage the memory by logically organize the basic unit of physical erase (erase block) into composite logical groupings (meta-blocks or logical group), where an erase block generally consists of a number of sectors. When an erase command is received, the specified sectors are checked against the memory system's control data. If the specified sectors span any full logical grouping, the full logical groupings can each be treated a whole and erased according to one process (such as performing a true, physical erase), while other sectors are “logically” erased at the sector level by standard techniques.

Provided herein are novel phosphors useful in the manufacture of white light emitting diodes. The phosphors provided by the invention are described by the formula: described by the formula:

ZnS_xSe_y:Cu,A

in which x and y are each independently any value between 0 and about 1, subject to the proviso that the sum of x and y is equal to any number in the range of between about 0.75 and about 1.25; wherein A is optional and comprises at least one additional element selected from the group consisting of: Ag, Al, Ce, Tb, Cl, I, Mg, and Mn, including mixtures thereof, and wherein Cu is present in any amount between about 0.0001% and about 5% in mole percent based on the total molar weight of said composition. Standard techniques used in phosphor deposition for the manufacture of light emitting diodes which comprise phosphors may be employed to produce LED's having a white light output when the phosphors of the invention are utilized.

Transgenic microbial strains are provided which contain the genes required for PHA formation integrated on the chromosome. The strains are advantageous in PHA production processes, because (1) no plasmids need to be maintained, generally obviating the required use of antibiotics or other stabilizing pressures, and (2) no plasmid loss occurs, thereby stabilizing the number of gene copies per cell throughout the fermentation process, resulting in homogeneous PHA product formation throughout the production process. Genes are integrated using standard techniques, preferably transposon mutagenesis. In a preferred embodiment wherein mutiple genes are incorporated, these are incorporated as an operon. Sequences are used to stabilize mRNA, to induce expression as a function of culture conditions (such as phosphate concentration), temperature, and stress, and to aid in selection, through the incorporation of selection markers such as markers conferring antibiotic resistance.

Normal cells, such as fibroblasts or other tissue or organ cell types, are genetically engineered to express biologically active, therapeutic agents, such as proteins that are normally produced in small amounts, for example, MIS, or other members of the TGF-beta family Herceptin(TM), interferons, andanti-angiogenic factors. These cells are seeded into a matrix for implantation into the patient to be treated. Cells may also be engineered to include a lethal gene, so that implanted cells can be destroyed once treatment is completed. Cells can be implanted in a variety of different matrices. In a preferred embodiment, these matrices are implantable and biodegradable over a period of time equal to or less than the expected period of treatment, when cells engraft to form a functional tissue producing the desired biologically active agent. Implantation may be ectopic or in some cases orthotopic. Representative cell types include tissue specific cells, progenitor cells, and stem cells. Matrices can be formed of synthetic or natural materials, by chemical coupling at the time of implantation, using standard techniques for formation of fibrous matrices from polymeric fibers, and using micromachining or microfabrication techniques. These devices and strategies are used as delivery systems via standard or minimally invasive implantation techniques for any number of parenterally deliverable recombinant proteins, particularly those that are difficult to produce in large amounts and/or active forms using conventional methods of purification, for the treatment of a variety of conditions that produce abnormal growth, including treatment of malignant and benign neoplasias, vascular malformations (hemangiomas), inflammatory conditions, keloid formation, abdominal or plural adhesions, endometriosis, congenital or endocrine abnormalities, and other conditions that can produce abnormal growth such as infection. Efficacy of treatment with the therapeutic biologicals is detected by determining specific criteria, for example, cessation of cell proliferation, regression of abnormal tissue, or cell death, or expression of genes or proteins reflecting the above.

The composition are comprised of a water soluble draw solute having surface active properties, i.e., a surfactant.

A convex paramutuel call auction implemented at a central market organizer computer includes receiving orders from market participants, calculating a quantity of accepted bids for each of the orders, and communicating to the participants the calculated quantity of accepted bids for each of the orders. Each order includes a specification by a participant of contingent claims on outcomes of a future event, a limit bid price, and a limit bid quantity. The calculation involves maximizing an objective function given by an approximate profit to the market organizer plus a weighted logarithmic penalty function. Because the formulation is convex, the solution may be computed in polynomial time using standard techniques, such as a path-following algorithm.

The construction of transgenic animal models of human Alzheimer's disease, and methods of using the models to screen potential Alzhe## disease therapeutics, are described. The models are characterized by pathologies similar to pathologies observed in Alzheimer's disease, based on expression of all three forms of the β-amyloid precursor protein (APP), APP695, APP751, and APP770, as well as various point mutations based on naturally occurring mutations, such as the London and Indiana familial Alzheimer's disease (FAD) mutations at amino acid 717, predicted mutations in the APP gene, and truncated forms of APP that contain the Aβ region. Animal cells can be isolated from the transgenic animals or prepared using the same constructs with standard techniques such as lipofection or electroporation. The transgenic animals, or animal cells, are used to screen for compounds altering the pathological course of Alzheimer's disease as measured by their effect on the amount of APP, β-amyloid peptide, and numerous other Alzheimer's disease markers in the animals, the neuropathology of the animals, as well as by behavioral alterations in the animals.

An apparatus and method for manufacturing and using a calibrated registration reference wafer in a semiconductor manufacturing facility. A reference reticle consisting of a 2-dimensional array of standard alignment attributes is exposed several times onto a photoresist coated semiconductor wafer using a photolithographic exposure tool. After the final steps of the lithographic development process the resist patterned wafer is physically etched using standard techniques to create a permanent record of the alignment attribute exposure pattern. The permanently recorded alignment attributes are measured for placement error using a conventional overlay metrology tool. The resulting overlay error data is used to generate a calibration file that contains the positions of the alignment attributes on the reference wafer. The reference wafer and calibration file can be used to determine the wafer stage registration performance for any photolithographic exposure tool.
