Abstract: A simple one pot sol-gel method for the synthesis of bi-metal nanostructures is based on non-noble metals (Fe, Co and Sn) and titanium. The method involves the synthesis of mixed metal nanoscale composites using low cost precursors which allow for the synthesis of desired nanocomposite materials with self-scarifying titanium or silica supports. The procedure does not require any surfactant or any need for pH controlled step. Applicants' method involves the in-situ generation of precursors and their simultaneous entrapment in a gel. This simple one pot synthesis allows for the synthesis of homogenous size, shape and distribution of targeted nanostructures. Further, this method can be applied for the preparation of various nanocomposite materials using different choices of metals and self-scarifying supports. Applicants also show that Pd, the noble metal based nanocomposite is feasible.

Abstract: A buffer composition for hybridization of a target nucleic acid is provided. The nucleic acid can include a nucleotide to be detected with a nucleic acid probe. The probe can contain a nucleotide sequence complementary to the target nucleic acid. The buffer can include a blocking nucleic acid having a nucleotide sequence complementary to a non-target nucleic acid having a nucleotide not to be detected corresponding to the nucleotide to be detected. The buffer composition can suppress non-specific hybridization to the nucleic acid probe even when a non-target nucleic acid is present. The use of the buffer composition can achieve excellent detection efficiency of the target nucleic acid.

Abstract: Regulated changes in gene expression underlie many biological processes, but globally profiling cell-to-cell variations in transcriptional regulation is problematic when measuring single cells. Transcriptome-wide identification of regulatory heterogeneities can be robustly achieved by randomly collecting small numbers of cells followed by statistical analysis. However, this stochastic-profiling approach blurs out the expression states of the individual cells in each pooled sample. Various aspects of the disclosure show that the underlying distribution of single-cell regulatory states can be deconvolved from stochastic-profiling data through maximum-likelihood inference. Guided by the mechanisms of transcriptional regulation, the disclosure provides mixture models for cell-to-cell regulatory heterogeneity which result in likelihood functions to infer model parameters.

Abstract: The present disclosure discloses an imaging system, method, and apparatus for identifying information of a hidden object. A light source generates a first beam of narrow-band light and a second beam of narrow-band light that has temporal fluctuations correlated with the first beam. The first beam is directed towards a first scattering surface and the second beam is directed towards a second scattering surface. The first scattering surface scatters the first beam to a scattered light that illuminates a hidden object, the hidden object reflects at least a portion of the scattered light towards the second scattering surface, the reflected light interferes with the second beam and produces an interference pattern on the second scattering surface. An image sensor detects irradiance of the interference pattern on the second scattering surface.

Abstract: A polarization and color sensitive pixel device and a focal plane array made therefrom. Each incorporates a thick color/polarization filter stack and microlens array for visible (0.4-0.75 micron), near infrared (0.75-3 micron), mid infrared (3-8 micron) and long wave infrared (8-15 micron) imaging. A thick pixel filter has a thickness of between about one to 10× the operational wavelength, while a thick focal plane array filter is on the order of or larger than the size or up to 10× the pitch of the pixels in the focal plane array. The optical filters can be precisely fabricated on a wafer. A filter array can be mounted directly on top of an image sensor to create a polarization camera. Alternatively, the optical filters can be fabricated directly on the image sensor.

Abstract: A spectrometer device for analysis of aerosol particles, dusts, and other microparticles and/or nanoparticles includes an electrospray ionization source supplying a particle stream to an aerodynamic lens that focuses and collimates a beam of particles. An electrostatic trap accepts the beam of particles and traps a single trapped particle at a time in the electrostatic trap to oscillate with a measurable amplitude and frequency. A sensor senses the amplitude and frequency, and a processor determines a calculated mass to charge ratio from the amplitude and frequency of oscillation of the trapped particle in real time. A method creates a focused stream of micro or nanoparticles, traps a single particle at a time in an electrostatic trap. The amplitude and frequency of the oscillation of the trapped particle is sensed. The mass to charge ratio is determined from the amplitude and frequency of oscillation. Particles can be accelerated into a target.

Abstract: A new system and method for FWI of common-offset GPR data, particularly targeting the dimensions and infilling material of buried objects. The method is useful in situations where clear isolated diffraction hyperbolas indicate the presence of an underground object, but the object's dimensions and filling may be unknown. The present invention acquires GPR data and applies advanced numerical methods to get the depth and size of the underground object in a very accurate manner. An embodiment of the invention includes five main steps: GPR data processing, ray-based analysis to set a good initial model, 3D to 2D transformation of data, effective SW estimation, and FWI.
Abstract: The present invention is generally related to the analysis of chemical compositions of hydrocarbons and hydrocarbon blends. This method, in particular embodiments, may apply specifically to the problem of analyzing extremely complex hydrocarbon-containing mixtures when the number and diversity of molecules makes it extremely difficult or impossible to realistically identify and quantify them individually in a reasonable timeframe. Particular SEC (size exclusion chromatography)-based methods and apparatus disclosed herein may be used to measure, e.g., the molecular size, weight, and/or volume, whether in absolute or relative manner, of the various components of eluate from the SEC stationary phase (e.g., a permeable gel). This analytical method is applicable on a wide variety of hydrocarbonaceous materials, and especially useful for, but not limited to oil, maltenes of oil, asphalt binders and asphalt binder blends, which may contain wide varieties of different types of additives, modifiers, and chemistries.
