Abstract: A systems and apparatus for measuring non-electroactive materials in liquids using electrochemical detection. A first electrical activity of a electroactive material is detected in absence of a target non-electroactive material (Step 120). A second electrical activity of the electroactive material is detected in presence of the target non-electroactive material (Step 130). A difference between the first and second electrical activities is obtained, and based on the obtained difference, a concentration of the target non-electroactive material is identified (Step 140).

Abstract: The nonlinear systems measurement system includes two signal generators generating different sinusoidal frequencies. A spectrum analyzer measures all signals. A single software program synchronizes the instruments. The fetched measurements are kept in data registers in correct sequence for feeding into two curve fitting routines. The sinusoidal signals are fed to a suitable combiner for the expected frequencies and dynamic range of the UUT. The combined signal is applied to the UUT. Via a software-controlled single-pole, triple-throw RF switch, the amplitude of the UUT output and the two input signals are measured at every power step as amplitude I1 and amplitude I2. The amplitude of the output component from the UUT at f1-f2 is measured as IMD2 and the output component at 2f1-f2 is measured as IMD3. The measured I1 and IMD2 are fed to the curve-fitting routine 1, yielding r1. The measured I2 and IMD3 are fed to curve-fitting routine 2, yielding r2.

Abstract: A plasma treatment has been used to modify the surface of BNNTs. In one example, the surface of the BNNT has been modified using ammonia plasma to include amine functional groups. Amine functionalization allows BNNTs to be soluble in chloroform, which had not been possible previously. Further functionalization of amine-functionalized BNNTs with thiol-terminated organic molecules has also been demonstrated. Gold nanoparticles have been self-assembled at the surface of both amine- and thiol-functionalized boron nitride Nanotubes (BNNTs) in solution. This approach constitutes a basis for the preparation of highly functionalized BNNTs and for their utilization as nanoscale templates for assembly and integration with other nanoscale materials.

Abstract: A facial image may be annotated with the plurality of facial landmarks. These facial landmarks may be points or regions of the face that are indicative, either alone or in combination with other facial landmarks, of at least one demographic characteristic. Demographic characteristics include, for example, age, race, and/or gender. Based on the demographic characteristic being analyzed, one or more of these facial landmarks may be selected and arranged into an input vector. Then, the input vector may be compared to one or more of the training vectors. An outcome of this comparison may involve in the given facial image being classified into a category germane to the analyzed demographic characteristic (e.g., an age range or age, a racial category, and/or a gender).

Abstract: The present invention provides for a lithium ion battery and process for creating such, comprising higher binder to carbon conductor ratios than presently used in the industry. The battery is characterized by much lower interfacial resistances at the anode and cathode as a result of initially mixing a carbon conductor with a binder, then with the active material. Further improvements in cycleability can also be realized by first mixing the carbon conductor with the active material first and then adding the binder.

Abstract: The present invention provides methods for reducing, reversing or inhibiting neovascularization in a tissue of a mammalian subject having a pathological condition involving neovascularization by administration in vivo of nanoceria particles (cerium oxide nanoparticles) to the subject. The method of the invention is useful, for example, for reducing, treating, reversing or inhibiting neovascularization in ocular tissue such as the retina, macula or cornea; in skin; in synovial tissue; in intestinal tissue; or in bone. In addition, the method of the invention is useful for reducing or inhibiting neovascularization in a neoplasm (tumors), which can be benign or malignant and, where malignant, can be a metastatic neoplasm. As such, the invention provides compositions, which contain nanoceria particles and are useful for reducing, treating, reversing or inhibiting angiogenesis in a mammalian subject.
