Disclosed are safe, simple and effective broad-spectrum treatments for halitosis and other microbial infections of the nondental upper respiratory tract useful to treat bacterial and other microorganism species, including anaerobic bacteria. Electromagnetic radiative energy including visible, and optionally, thermal, RF and / or microwave wavelengths, is topically applied to internal surfaces of the upper respiratory tract to destroy or incapacitate superficial microorganisms without the use of antibiotics. One useful apparatus is a handheld energy applicator having a light output head suitable for treating the back of the tongue and the tonsils and which may be interchangeably provided with extensions to reach the sinuses. The energy applicator can be supported and guided by a mounting device held between the subject's teeth, if desired. Useful embodiments of the invention include preparative treatment of the target surfaces with a photosensitizing agent such as an oxidizing agent or a complementary stain. Optionally a pre-treament procedure may be employed to remove detritus and microfloral overgrowths that may mask more deeply resident target microorganisms. Novel treatments include treatment of halitosis by destruction of bacterial species associated with halitosis, such as Atopobium parvulum, by application of non-ionizing radiative energy to the tonsils and the back of the tongue.

An alloy having a large band gap range is used in a multijunction solar cell to enhance utilization of the solar energy spectrum. In one embodiment, the alloy is In1−xGaxN having an energy bandgap range of approximately 0.7 eV to 3.4 eV, providing a good match to the solar energy spectrum. Multiple junctions having different bandgaps are stacked to form a solar cell. Each junction may have different bandgaps (realized by varying the alloy composition), and therefore be responsive to different parts of the spectrum. The junctions are stacked in such a manner that some bands of light pass through upper junctions to lower junctions that are responsive to such bands.

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.

The light emitting device is made by forming the multiple layers of quantum dots over a light source and then forming an encapsulant over the multiple layers of quantum dots. The multiple layers of quantum dots can be used to produce broad-spectrum color light, such as white light.

Rice plants are disclosed with two separate, but synergistic mechanisms for resistance to herbicides that normally inhibit a plant's acetohydroxyacid synthase (AHAS) enzyme. The herbicide resistance of plants with both resistance mechanisms is substantially greater than one would expect from a simple combination of the two types of resistance. The first of the two resistance mechanisms is a metabolic pathway that is not fully understood, but that does not itself involve a mutant AHAS enzyme. The second resistance mechanism is a mutant AHAS enzyme, an enzyme that shows direct resistance to levels of herbicide that normally inhibit the enzyme, in both in vivo and in vitro assays. Besides controlling red rice, many AHAS-inhibiting herbicides also effectively control other weeds that are common in rice fields. Several of these herbicides have residual activity, so that a treatment controls both existing weeds as well as weeds that sprout later. No herbicide currently available for use on rice has residual activity against a broad spectrum of weeds including red rice. With effective residual activity against red rice and other weeds, rice producers now have a weed control system superior to those currently used.

A rare earth-activated terbium-containing garnet phosphor is capable of absorbing radiation in the range from near UV to blue and emitting a broad spectrum of visible light in the range from about 490 nm to about 770 nm. The emission of the phosphor under an excitation at 450 nm exhibits a peak in the range of maximum sensitivity of the human eye. A light source combining a UV / blue LED and this phosphor can provide a white light that is on or near the Planckian locus and may be useful for general illumination.
