Abstract: The power turbine system includes two power turbines communicating with an ion transport membrane (ITM) reactor. Heavy liquid fuel is atomized and burned within the reactor to drive the first turbine, with the first turbine producing useful power. Exhaust from the first turbine is recycled back into the reactor. The reactor includes a series of concentric cylindrical ion transport membranes that separate atmospheric and exhaust gases into suitable components for combustion therein, with at least some of the gases being “cracked” to alter their molecular structure for further combustion to power the second turbine. The second turbine drives a compressor to supply air to the reactor. At least one of the ITMs precludes atmospheric nitrogen from the combustion processes, with the resulting exhaust including pure water and carbon dioxide. The carbon dioxide is either recycled into the reactor to facilitate fuel atomization, or compressed for sequestration.

Abstract: Errors in software may be detected via the use of design rule spaces and architecture root detection. Design rule spaces may reveal multiple overlapping modular structures of a software system, and reveal structural relations among error-prone files and structural problems contributing to error-proneness. Root detection may extract a few groups of architecturally connected files, which may be connected through problematic architecture relations that propagate errors among these files, and thus influence system error-proneness. The root detector may locate the core architecturally connected file groups that contribute to the error-proneness of a system. The root detection process may, beginning with a set of error-prone files, search and link other files that are architecturally related. The output of the root detection process may be a set of design rule spaces ordered by the number of error-prone contained therein.
Abstract: A central question in cancer therapy is how individual cells within a population of tumor cells respond to drugs designed to arrest their growth. However, the absolute growth of cells, their change in physical mass, whether cancerous or physiologic, is difficult to measure directly with traditional techniques. Embodiments of the invention provide live cell interferometry (LCI) for rapid, realtime quantification of cell mass in cells exposed to a changing environment. Overall, LCI provides a conceptual advance for assessing cell populations to identify, monitor, and measure single cell responses, such as to therapeutic drugs.

Abstract: Methods of identifying subjects at increased risk of cancer, based upon detection of biofilms and/or biofilm-associated microbes within a subject, are disclosed. Therapies designed to prevent formation and/or reduce the size of biofilms in a subject identified to be at increased risk of cancer based upon detection of biofilms and/or biofilm-associated microbes are disclosed. In particular embodiments, the invention provides for identification of a subject at elevated risk of developing or having colorectal cancer and/or a colorectal adenoma, based upon detection of a biofilm and/or biofilm-associated bacteria within the gastrointestinal tract of the subject (optionally, within a biopsy specimen and/or stool sample of such subject). Therapies involving administration of an antibiotic agent and/or a probiotic agent to a subject, to prevent or reduce biofilm formation within the gastrointestinal tract of the subject, optionally provided in combination with additional cancer therapy, are also disclosed.

Abstract: System and method of concentrating (or aligning) analytes at a droplet-bulk solution interface as a means of enhancing a detection sensitivity of the analytes at electrodes in a fluidic channel. A number of differing types of intermolecular forces and chemicals or materials can be employed to accomplish the concentrating (and/or aligning). For example, a measurement analogous to a conventional electrical impedance spectroscopy (EIS) measurement can be made by bringing an analyte (e.g., a molecule to be detected) to the edge of a droplet, and in so doing, positioning the analyte close to an electrode surface to aid in detection.

Abstract: The present invention provides a hot-carrier photoelectric conversion method. The method includes a hot-carrier photoelectric conversion device having a P-type semiconductor layer, an N-type semiconductor layer, and an inorganic conducting light-absorbing layer. The inorganic conducting light-absorbing layer is formed between the P-type semiconductor layer and the N-type semiconductor layer, and an electric field is formed between the P-type semiconductor layer and the N-type semiconductor layer. Moreover, photons are absorbed by the inorganic conducting light-absorbing layer to create electrons and holes. The electrons and holes are respectively shifted by the electric field or diffusion effect to the N-type semiconductor layer and the P-type semiconductor layer, so that the electrons and the holes are respectively conducted outside to create electric energy.
