  • Patent number: 8501486
    Abstract: Protein phosphorylation is a major post-translational modification and it plays a pivotal role in numerous cellular functions. We present a composition that includes a soluble nanopolymer core functionalized with groups having an affinity for either metal ion or metal oxides which can be used for phosphopeptide enrichment. Exemplary compounds including PolyMAC-Zr, PolyMAC-Fe and PolyMAC-Ti demonstrate outstanding reproducibility, exceptional sensitivity, fast chelation time, and high phosphopeptide recovery from standard mixtures that include phosphorylated peptides. The composition can be used for phosphoproteome isolation from samples of medicinal, diagnostic or biological interest such as malignant breast cancer cells. Such compositions were used for the quantitative analysis of the changes in the tyrosine phosphoproteome in highly invasive breast cancer cells after induction of Syk kinase, a potent suppressor of tumor growth and metastasis.

  • Patent number: 8499599
    Abstract: A laser nanoforming system and method for forming three-dimensional nanostructures from a metallic surface. A laser beam is directed to hit and explode an ablative layer to generate a shockwave that exerts a force on the metallic surface to form an inverse nanostructure of an underlying mold. A dry lubricant can be located between the metallic surface and mold to reduce friction. A confinement layer substantially transparent to the laser beam can confine the shockwave. A cushion layer can protect the mold from damage. A flyer layer between the ablative layer and metallic surface can protect the metallic surface from thermal effects of the exploding ablative layer. The mold can have feature sizes less than 500 nm. The metallic surface can be aluminum film. The dry lubricant can be sputtered Au—Cr film, evaporated Au film or a dip-coated PVP film or other dry lubricant materials.

  • Publication number: 20130189156
    Abstract: A system and method for decontamination of product is described. An object to be treated, which may be a food product or a medical device, is placed in a substantially closed dielectric container with a working gas. The container is placed in an apparatus capable of producing a controlled electrical discharge so as to create reactive ion species within the package. The object to be treated may be exposed either the immediate products of the electrical discharge or the long lasting reactive ion species, or both, so as to treat the object to reduce or eliminate specific contaminants, which may be biological pathogens or the cause of product spoilage, or inorganic contaminants. The reactive ion species may result from an atmospheric non-equilibrium plasma (ANEP) formed by the apparatus and the treatment may be performed without significantly increasing the bulk temperature of the object being treated.

  • Patent number: 8474254
    Abstract: A system and method for performing a floating function in an earthmoving implement of an earthmoving machine without physically connecting chambers within a hydraulic actuator that is adapted to raise and lower the earthmoving implement. The system includes a device for delivering a pressurized fluid to and receiving pressurized fluid from the actuator, a valve for compensating for differences in volume between chambers of the actuator, and an electronic control circuit that includes electronic sensors for sensing the pressures in the chambers of the actuator, and a controller for receiving outputs of the sensors. The controller calculates an amount of the pressurized fluid that, when delivered to or received from the actuator, achieves a substantially constant pressures in the chambers of the actuator and enables the earthmoving implement to float regardless of motion of the actuator.

  • Patent number: 8470151
    Abstract: This paper presents a microfluidic pumping approach using traveling-wave dielectrophoresis (tw-DEP) of microparticles. Flow is generated directly in the microfluidic devices by inducing electromechanical effects in the fluid using microelectrodes. The fluidic driving mechanisms due to the particle-fluid and particle-particle interactions under twDEP are analyzed, and the induced flow field is obtained from numerical simulations. Experimental measurements of the flow velocity in a prototype DEP micropumping device show satisfactory agreement with the numerical predications.

  • Patent number: 8461534
    Abstract: A system and method are described for capturing and analyzing gamma rays from neutron excitation of a region in 3-space being analyzed for explosives. A processor analyzes the results, determining whether underground explosives are present in a particular region of the ground. In one embodiment, one gamma ray energy band is used to infer an amount of silicon in the region, while another indicates the combined amount of silicon and nitrogen. The concentration of nitrogen in the region is inferred and used to trigger an “explosive found” or a “no explosive found” signal. In other embodiments, the system or method uses inferences about other elemental constituents of the ground being examined, sometimes taking as input analyzes from prior scans, and providing output indicating the likelihood of the presence of explosives in the region.
