Abstract:
A method for making a heteroepitaxial layer. The method comprises providing a semiconductor substrate. A seed area delineated with a selective growth mask is formed on the semiconductor substrate. The seed area comprises a first material and has a linear surface dimension of less than 100 nm. A heteroepitaxial layer is grown on the seed area, the heteroepitaxial layer comprising a second material that is different from the first material. Devices made by the method are also disclosed.
Abstract:
In one embodiment, the invention provides a method of treating a subject suffering from a breast cancer tumor which is non-responsive or intrinsically resistant to anti-estrogen therapy comprising administering a therapeutically effective amount of an inhibitor of alternative (ALT) non-homologous end joining (NHEJ) factor to the subject.In another embodiment the invention provides a method of treating a subject who suffers from a pancreatic cancer which is non-responsive to chemotherapy and/or radiation comprising co-administering a therapeutically effective amount of PARP1 inhibitor and a DNA ligase IIIα inhibitor to the subject. Related diagnostic methods, nucleic acid arrays, devices and kits are also provided.
Abstract:
Apparatus, systems, and methods using an optically pumped gas filled hollow fiber laser can be implemented in a variety of applications. In various embodiments, operation of an optically pumped gas filled hollow fiber laser is based on population inversion in the gas. Additional apparatus, systems, and methods are disclosed.
Abstract:
An analytical device such as a flow cytometer is provided in which a fluid sample flowing through a channel is focused into multiple, parallel particle streams by an acoustic wave field extending across the channel. Each stream is then presented to an individual detector to allow for simultaneous interrogation of the multiple streams and thus, high-throughput analysis of the fluid sample.
Abstract:
The present invention is directed to the use of isotopically labeled citrulline for gnosing the presence or absence of a bacterial infection in the lungs of a patient.
Abstract:
Apparatus and methods comprise examination of a subject using images of the subject. The images can provide a non-invasive analysis technique and can include a plurality of images of a portion of the subject at different times a temperature stimulus applied to the subject. An image of the portion of the subject can be aligned such that each pixel of the image corresponds to the same point on the subject over a sequence of images of the portion. The sequence of images can be processed after aligning the images such that data is extracted from the images. The extracted data can be used to make decisions regarding the health status of the subject. Additional apparatus, systems, and methods are disclosed.
Abstract:
The present invention is directed to novel non-invasive diagnostic and therapeutic tools/compounds comprising a hybride cyclic peptide which utilizes a cyclic peptide chelating group wherein the compound binds to a MSH receptor to image and treat cancers, especially, melanoma, including metastatic melanoma in vivo. The present invention represents a clear advance in the art which presently relies on tissue biopsy for diagnoses of these cancers. The novel imaging probes are capable of detecting cancerous melanoma cells, as well as their metastatic spread in tissues. This represents a quantum step forward in the diagnosis and treatment of melanoma, including metastatic melanoma using non-invasive molecular imaging techniques. The novel probes of the present invention will also be useful to initiate therapy for melanoma as well as monitor patients response to chemotherapy treatments and other interventions or therapies used in the treatment of melanoma/metastatic melanoma. Compound according to the present invention may be used as diagnostic tools for a number of conditions and diseases states as well as therapeutic agents for treating such conditions and disease states.
Abstract:
An image and video processing system and methods based on amplitude-modulation frequency-modulation (“AM-FM”) demodulation to provide high quality reconstructions, both visually and quantitatively. The system and methods reconstructs an image based on a Regularized Optimization (“RO”) of estimates to attain a small number of locally coherent components and simultaneously enforce a piecewise smooth constrain for one or more amplitude functions.
Abstract:
Photon-based radiosurgery is widely used for treating local and regional tumors. The key to improving the quality of radiosurgery is to increase the dose falloff rate from high dose regions inside the tumor to low dose regions of nearby healthy tissues and structures. Dynamic photon painting (DPP) further increases dose falloff rate by treating a target by moving a beam source along a dynamic trajectory, where the speed, direction and even dose rate of the beam source change constantly during irradiation. DPP creates dose gradient that rivals proton Bragg. Peak and outperforms Gamma Knife® radiosurgery.
Abstract:
A system and methods for building a map non-invasively (i.e. mapping of occluded and non-occluded obstacles) based on a small number of wireless channel measurements. Approaches for building an obstacle map are based on coordinated space, random space and frequency sampling, such that the sparse representation of the map in space, wavelet or spatial variations, are exploited in order to build the map with minimal sensing.
