Broad-spectrum antibiotic. A broad-spectrum antibiotic is an antibiotic that acts on the two major bacterial groups, gram-positive and gram-negative, or any antibiotic that acts against a wide range of disease-causing bacteria.

Nanosilver-containing antibacterial and antifungal granules and methods for preparing and using the same

The present invention relates to nanosilver-containing antibacterial and antifungal granules ("NAGs"). The NAGs have longlasting inhibitory effect on a broad-spectrum of bacteria and fungi, which include, but are not limited to, Escherichia coli, Methicillin resistant Staphylococcus aureus, Chlamydia trachomatis, Providencia stuartii, Vibrio vulnificus, Pneumobacillus, Nitrate-negative bacillus, Staphylococcus aureus, Candida albicans, Bacillus cloacae, Bacillus allantoides, Morgan's bacillus (Salmonella morgani), Pseudomonas maltophila, Pseudomonas aeruginosa, Neisseria gonorrhoeae, Bacillus subtilis, Bacillus foecalis alkaligenes, Streptococcus hemolyticus B, Citrobacter, and Salmonella paratyphi C. The NAGs contain ground stalk marrow of the plant Juncus effusus L. which has been dispersed with nanosilver particles. The nanosilver particles are about 1-100 nm in diameter. Each of the nanosilver particles contain a metallic silver core which is surrounded by silver oxide. The present invention also provides a process for making the NAGs. The NAGs can be used in a variety of healthcare and industrial products. Examples of the healthcare products include, but are not limited to, ointments or lotions to treat skin trauma, soaking solutions or cleansing solutions for dental or women hygiene, medications for treating gastrointestinal bacteria infections, sexual related diseases, and eye diseases. Examples of industrial products include, but are not limited to, food preservatives, water disinfectants, paper disinfectants, construction filling materials (to prevent mold formation).

Method and Apparatus for Signal Detection, Classification and Estimation from Compressive Measurements

The recently introduced theory of Compressive Sensing (CS) enables a new method for signal recovery from incomplete information (a reduced set of “compressive” linear measurements), based on the assumption that the signal is sparse in some dictionary. Such compressive measurement schemes are desirable in practice for reducing the costs of signal acquisition, storage, and processing. However, the current CS framework considers only a certain task (signal recovery) and only in a certain model setting (sparsity).
We show that compressive measurements are in fact information scalable, allowing one to answer a broad spectrum of questions about a signal when provided only with a reduced set of compressive measurements. These questions range from complete signal recovery at one extreme down to a simple binary detection decision at the other. (Questions in between include, for example, estimation and classification.) We provide techniques such as a “compressive matched filter” for answering several of these questions given the available measurements, often without needing to first reconstruct the signal. In many cases, these techniques can succeed with far fewer measurements than would be required for full signal recovery, and such techniques can also be computationally more efficient. Based on additional mathematical insight, we discuss information scalable algorithms in several model settings, including sparsity (as in CS), but also in parametric or manifold-based settings and in model-free settings for generic statements of detection, classification, and estimation problems.

A light source apparatus including light spectrum-converting materials that emit light primarily over large portions of the 360 nm-480 nm and the 590-860 nm spectral range is provided. This apparatus provides a cooled, high-luminance, high-efficiency light source that can provide a broader spectrum of light within these spectral ranges than has been cost-practical by using many different dominant peak emission LEDs. Up to 15% of the output radiant power may be in the spectral range 350-480 nm in one embodiment of this device, unless a specific separate source and lamp operating mode is provided for the violet and UV. Control methods for light exposure dose based on monitoring and controlling reflected or backscattered light from the illuminated surface and new heat management methods are also provided. This flexible or rigid light source may be designed into a wide range of sizes or shapes that can be adjusted to fit over or around portions of the bodies of humans or animals being treated, or mounted in such a way as to provide the special spectrum light to other materials or biological processes. This new light source can be designed to provide a cost-effective therapeutic light source for photodynamic therapy, intense pulsed light, for low light level therapy, diagnostics, medical and other biological applications as well as certain non-organic applications.

Technology for processing high-concentration organic wastewater in composite electrochemical method

The invention relates to a technology for processing high-concentration organic wastewater in a composite electrochemical method, which comprises the main four steps of: pH adjustment, multidimensional electrocatalytic oxidization processing, micro coupling electric fenton reaction oxidation processing and coagulating sedimentation processing. The invention has the technical advantage that the technology has good breaking, chain scission, degradation effects to benzene ring organics, heterocyclic organics, polycyclic organics, macromolecule organics and sustaining organics, which have the most difficulty to degradation. Besides, the technology has no obvious selection to various kinds of high-concentration organic wastewater, has broad-spectrum processing effect, and is an effective measurement for pre-processing to high-concentration organic wastewater having difficulty to degradation. The invention is characterized in that the technology uses second-grade electrochemical processing equipment to realize third-grade advanced oxidation combination processing, effectively utilizes H2O2 and Fe2+ generated by the second-grade electrochemical processing equipment, and makes fenton oxidated and coupled in a micro reactor. During the technological processes, the oxidation capacity is strong to weak, and has reasonable distribution. The pH valve of wastewater does not need repeatedly adjusting. The invention has the obvious characteristics of low electric consumption, little medicine consumption, high processing efficiency, and good controllability.

Method and system for exploiting parallelism on a heterogeneous multiprocessor computer system

In a multiprocessor system it is generally assumed that peak or near peak performance will be achieved by splitting computation across all the nodes of the system. There exists a broad spectrum of techniques for performing this splitting or parallelization, ranging from careful handcrafting by an expert programmer at the one end, to automatic parallelization by a sophisticated compiler at the other. This latter approach is becoming more prevalent as the automatic parallelization techniques mature. In a multiprocessor system comprising multiple heterogeneous processing elements these techniques are not readily applicable, and the programming complexity again becomes a very significant factor. The present invention provides for a method for computer program code parallelization and partitioning for such a heterogeneous multi-processor system. A Single Source file, targeting a generic multiprocessing environment is received. Parallelization analysis techniques are applied to the received single source file. Parallelizable regions of the single source file are identified based on applied parallelization analysis techniques. The data reference patterns, code characteristics and memory transfer requirements are analyzed to generate an optimum partition of the program. The partitioned regions are compiled to the appropriate instruction set architecture and a single bound executable is produced.
