A method for determining a composition of an object using a spectral x-ray system is provided. X-ray photons of at least two different energies are transmitted through the object. The energy of each detected x-ray photon using a detector in the x-ray system is estimated.
A method for providing an adiabatic RF pulse that is an inversion or refocusing pulse for a RF pulse sequence is provided. A linear phase frequency profile (F.sub.lp(.omega.)) is determined for the adiabatic RF pulse.
Unlike traditional anti-malware products that enforce one narrow definition of security, this flexible, policy-based Android application management platform enables customized enterprise-specific security, privacy, and compliance policy enforcement.
A composition of matter comprising an amphiphilic star polymer, the star polymer comprising a crosslinked microgel core and 6 or more independent polymer arms covalently linked to the core, the 6 or more arms each comprising a hydrophilic polymer chain segment and a hydrophobi
Researchers in Prof. Mark Kay's laboratory have developed a robust vector that combines the ease of plasmid preparation with the stable expression achieved by minicircle vectors.
This optical gyroscope uses a unidirectional coupled-resonator waveguide to enhance the Sagnac effect. Thus, this device offers greater sensitivity to rotation than conventional resonant or interferometric fiber-optic gyroscopes.
Light with a narrowband spectrum is launched into the FBG, at a wavelength located on one of the two edges of the reflection peak of the FBG, i.e., at a wavelength where the FBG transmits, rather than reflects, light.
An optical sensor includes an optical coupler configured to receive a first optical signal and to split the first optical signal into a second optical signal and a third optical signal.
An optical sensor includes at least one optical coupler and an optical waveguide in optical communication with the at least one optical coupler. The optical waveguide is configured to receive a first optical signal from the at least one optical coupler.
An acoustic sensor and a method of fabricating an acoustic sensor are provided. The acoustic sensor includes at least one photonic crystal structure and an optical fiber having an end optically coupled to the at least one photonic crystal structure.
