Abstract: Components, systems and methods for generating variable frequency AC voltage from a DC power supply are described. The components include a full-bridge (FB) parallel load resonant (PLR) converter which operates in discontinuous conduction mode. The PLR converter includes MOSFETs in an H-bridge configuration and employs a topology which minimizes inductance. The PLR converter can be coupled to a single or poly-phase bridge for use as an inverter. The inverter can be used to produce an AC sinusoidal waveform from a low voltage, high current DC power supply. Systems and techniques for modulating the output from the PLR converter to produce an AC sinusoidal waveform having desired characteristics, including frequency and voltage, are also provided. The PLR converter can also be coupled to a rectifier for use as a DC-DC converter.
Abstract: Buddleja ‘Blue Chip’ is a new and distinct variety of butterfly bush that has the following unique combination of desirable features that are outstanding in a new variety. 1. Moderate vigor resulting in compact growth habit. 2. Ease of asexual propagation using softwood or semi-hardwood cuttings. 3. Spreading growth habit with multi-branched stems. 4. Male sterility, and low female fertility and reduced seed set, resulting in less opportunity for seedlings to originate in the landscape setting. 5. Blue flower color.

Abstract: Provided is a peptide, peptide multimer or fusion protein containing such peptide which binds to the gut of sap-sucking insects, e.g., aphids. When bound, this peptide inhibits the binding of targeted virus to the insect gut. When this peptide or tandem repeat peptide is expressed (or is expressed as part of a fusion protein) in the fluids of transgenic plants, it is taken up by the insect with the sap, binds to gut receptors and thereby inhibits transmission of the virus from plant to plant via the insect vector. Thus, the use of such transgenic plants blocks or reduces the transmission of the targeted virus and others which share the peptide binding site within the insect gut among plants susceptible to the virus and thereby reduces losses due to viral infection.

Abstract: A method and biosensor device for detecting single strand target nucleic acid by cyclic voltammetry is described. A porous silicon chip is linked to bound DNA probe complementary to the target nucleic acid. The device is particularly useful for detecting microorganisms and viruses that may be pathogenic or cancer genes, however any target nucleic acid can be detected by using a specific DNA probe.

Abstract: Analytical tools and methods employing processing of channel current blockade measurements to detect or assess changes in environmental conditions generally, and more specifically, to detect and assess interactions between a blockade-producing auxiliary molecule in the channel and either the surrounding conductive medium generally or molecules in that conductive medium. The auxiliary molecule is disposed within the channel in order to generate a highly structured channel current blockade signal. The blockade signal resulting from inducing ionic current flow through the channel with auxiliary molecule present, is based on an auxiliary molecule chosen to be highly susceptible to modulation when the auxiliary molecule interacts with other molecules in the surrounding conductive medium, or when it otherwise is modified or affected at the molecular level by changes in the physical or chemical conditions of that surrounding medium.

Abstract: A process for hydrolyzing whole grain or whole plant biomass after an Ammonia Fiber Explosion (AFEX) process step is described. The process preferably uses a biomass that is hydrolyzed using a different combination of enzymes (amylase, cellulase and hemicellulase) to sugars for fermentation to produce ethanol. Harvesting the whole plant inclusive of grains and stalk for ethanol bio-processing is an economical route for future biorefineries. In addition to sugars, various value-added products like proteins and oil can be co-generated.

Moderate vigor resulting in compact growth habit. 2. Ease of asexual propagation using softwood or semi-hardwood cuttings. 3. Upright growth habit with flowers borne stiffly on upright shoots. 4. Low female fertility and reduced seed set, resulting in less opportunity for seedlings to originate in the landscape setting. 5. Bright pink flower color, unknown in any other butterfly bush variety.
Abstract: Poly(glycolide) polymers are disclosed. The polymers generally include a polymerized alkynyl-substituted glycolide having a polymer backbone with one or more alkynyl groups appended thereto. The alkynyl groups provide reactive sites for further functionalization of the polymer, for example by reaction with azide derivatives (e.g., azide-substituted organic compounds). Alkynyl and azide groups react via the “click” chemistry mechanism to form functional groups covalently bonded to the polymer via a triazole link. The polymers are biodegradable and can be used to deliver drugs or other therapeutic substances (e.g., large biomolecules such as single strand RNA) at targeted locations in a patient's body and/or at controlled release rates.

Abstract: An acceleration-triggered or shock-triggered, smart, tunable MEMS switch that may function as both a classic accelerometer and an acceleration threshold detector. A parallel element MEMS device has a stationary and a movable element forming a capacitor. Varying acceleration moves the movable member with respect to the stationary member, thereby changing the capacitance of the device. The capacitance varying may be used, in cooperation with appropriate circuitry, to provide a signal representative of instantaneous acceleration. By applying a biasing voltage, the movable element may be positioned in a predetermined fashion such that acceleration of a predetermined magnitude causes the movable element to pull in (snap down). The movable and stationary elements may function as a switch such that when the predetermined acceleration or shock level occurs, electrodes close, a current flows between the elements so that an external device such as an air bag may be activated.

Abstract: Rice plants are disclosed with multiple sources of resistance to herbicides that normally inhibit a plant's acetohydroxyacid synthase (AHAS) enzyme. 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 one treatment can control both existing weeds and weeds that sprout later. With effective residual activity against red rice and other weeds, rice producers now have a weed control system superior to those that are currently available commercially.

Abstract: SHE, a Starch Hydrolytic Enzyme active in maize endosperm (Zea mays), and the cDNA sequence encoding SHE are disclosed. The specificity of native, purified SHE is similar, in general terms, to previously known alpha-amylases. However, the activity of SHE toward amylopectin results in hydrolysis products that are distinctly different from those of other alpha-amylases. SHE, and its homologous equivalents in other plants such as rice, Arabidopsis, apple and potato, can be used in starch processing for generating different, e.g., larger sized, alpha-limit dextrins for industrial use, as compared to those generated by previously known alpha-amylases or other starch hydrolytic enzymes. In addition, modification of the expression of this enzyme in transgenic maize plants or in other transgenic organisms (including bacteria, yeast, and other plant species) can be useful for the generation of novel starch forms or altered starch metabolism.
