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 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.
A doped superfluorescent fiber source (SFS) has an enhanced mean wavelength stability. A method stabilizes the mean wavelength of a SFS. The method includes providing an SFS including a doped fiber.
A photonic-bandgap fiber includes a photonic crystal lattice with a material having a first refractive index and a pattern of regions formed therein. Each of the regions has a second refractive index lower than the first refractive index.
A method estimates a nonlinearity profile of a material. The method includes providing a magnitude of a transform of a measured nonlinearity profile measured from the material.
An optical fiber includes a cladding with a material having a first refractive index and a pattern of regions formed therein. Each of the regions has a second refractive index lower than the first refractive index.
An apparatus characterizes at least one fiber Bragg grating. The apparatus includes a laser pulse source, an optical spectrum analyzer, and multiple optical paths. A first optical path includes a pulse stretcher and an attenuator.
A method and apparatus models one or more electromagnetic field modes of a waveguide. The method includes sampling a two-dimensional cross-section of the waveguide.
To determine the phase and magnitude of the complex electric field of
weak ultra-short pulses we propose to use a dummy strong pulse time
delayed relative to the weak pulse that needs to be characterized. This
