  • Patent number: 8346534
    Abstract: The present invention provides a method and a system for automatic keyword extraction based on supervised or unsupervised machine learning techniques. Novel linguistically-motivated machine learning features are introduced, including discourse comprehension features based on construction integration theory, numeric features making use of syntactic part-of-speech patterns, and probabilistic features based on analysis of online encyclopedia annotations. The improved keyword extraction methods are combined with word sense disambiguation into a system for automatically generating annotations to enrich text with links to encyclopedic knowledge.

  • Publication number: 20120168721
    Abstract: Methods of forming a graphene-based device are provided. According to an embodiment, a graphene-based device can be formed by subjecting a substrate having a dielectric formed thereon to a chemical vapor deposition (CVD) process using a cracked hydrocarbon or a physical vapor deposition (PVD) process using a graphite source; and performing an annealing process. The annealing process can be performed to temperatures of 1000 K or more. The cracked hydrocarbon of the CVD process can be cracked ethylene. In accordance with one embodiment, the application of the cracked ethylene to a MgO(111) surface followed by an annealing under ultra high vacuum conditions can result in a structure on the MgO(111) surface of an ordered graphene film with an oxidized carbon-containing interfacial layer therebetween. In another embodiment, the PVD process can be used to form single or multiple monolayers of graphene.

  • Publication number: 20120143495
    Abstract: Methods and systems for indoor navigation utilize a smartphone equipped with various sensors. When a person whose initial position is unknown, and in some circumstances whose sight has been impaired, specifies a destination, the navigation system will calculate the coordinates of his/her present location from the sensor readings. It will then calculate the distance to be traveled to the destination and form routes to direct him/her towards the desired location. These steps are carried out using sensor readings and in some cases magnetic maps of the interiors of buildings stored on the smartphone. In some cases dynamic time warping (“DTW”) is used to align a recorded signature of the person's movement through the building with a stored magnetic map in order to identify the person's location within the building.

  • Publication number: 20120118153
    Abstract: Fluorinated metal-organic frameworks (“FMOFs”) are capable of adsorbing and desorbing hydrocarbons, namely, C6-C8 hydrocarbon oil components (n-hexane, cyclohexane, benzene and toluene). FMOFs can be arranged in a variety of configurations and have internal hollow channels and cavities. In FMOFs, hydrogen atoms have been substituted completely or partially with fluorine atoms or fluorinated groups in each linking organic ligand. These FMOFs can adsorb C6-C8 hydrocarbons, up to 500 kg/m3 as demonstrated for toluene, through a combination of superhydrophobicity and capillary action. No water adsorption was detectable even under extreme conditions including moist air near 100% relative humidity and immersion in water for multiple weeks, demonstrating far superior water resistance to BPL carbon and zeolites. These materials are stable and can be readily recycled by simple desorption many times.

  • Publication number: 20120104243
    Abstract: Silver nanoparticles as a sample matrix for Matrix Assisted Laser Desorption Ionization (MALDI) along with a novel method for nanoparticle development is described herein. The silver nanoparticles were generated from silver ions on the surface of a MALDI plate utilizing a Soft Landing Ion Mobility (SLIM) instrument. Upon interaction with the surface the incident silver ions were labile and aggregated into the nanoparticle structures in a time dependent fashion. Post landing analyses were completed by Time of Flight mass spectrometry (TOF), and of particular interest in the spectra were the elimination of low mass interference peaks that generally plague organic based matrices. The approach of the present invention significantly decreases sample preparation time and may lead to a preparation free MALDI source by soft landing a matrix directly on the sample surface.

  • Publication number: 20120076832
    Abstract: Therapeutic particles contain metal ions and are characterized by the use of unique ligand sets capable of making the metal ion complex soluble in biological media to induce selective toxicity in diseased cells. The particles may comprise a polymeric base particle, at least one pharmaceutically active metal ion, including metal ions from more than one metal element, a ligand that is covalently attached to the polymeric base particle and attached to the metal ion via a stimuli-responsive bond, and a cell targeting component. When the metal ion-containing particle enters a pre-defined environment, the ligands binding the metal to the particle are broken, triggering release of the free metal ion while the original ligands remain covalently bound to the particle.

  • Publication number: 20120065614
    Abstract: A new technique to stabilize transition metal phosphors in a wide variety of stimuli-sensitive polymers and gels is disclosed herein. Other than stabilization in stimuli sensitive/biocompatible matrix some of these transition metal based phosphors are also shown to act as phosphorescent crosslinkers that physically or chemically crosslink polymeric chains to form micro/nanoparticles. The microspheres/nanospheres of the present invention show decreased size and photoluminescence enhancement with particularly high sensitization at physiological pH and temperature. The so formed phosphorescent micro/nanospheres are useful for biological or environmental applications including biological labeling, imaging, and optical sensing. The techniques in the present invention enable usage of imaging agents and sensors at very low concentrations and also minimize or eliminate the usage of toxic chemical crosslinkers typically used to synthesize polymeric micro/nanoparticles.
