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.
Prof. Jim Collman at Stanford and Dr. Paul Herrmann at Loma Linda Medical School have developed compositions and methods to inhibit platelet and platelet-driven clotting activity by a novel pathway.
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 Dr. Fan Yang's lab have developed 3D tissue engineering scaffolds with dynamic, temporally and spatially controllable macropore formation.
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.
An optical hydrophone that is insensitive to hydrostatic pressure, yet capable of measuring acoustic pressures as low as the background noise in the ocean in a broad frequency range of 1 Hz to 100 kHz is reported.
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.
