An alexandrite pumped Nd:glass regenerative amplifier for chirped pulse amplification
(Elsevier, 1992-08-15)
An alexandrite pumped, Nd:glass regenerative amplifier is demonstrated. This amplifier has been used with chirped pulse amplification to produce millijoule, picosecond pulses. Using this technique the overall gain bandwidth ...
Quantitative numerical analysis of g strain in the EPR of distributed systems and its importance for multicenter metalloproteins
(Elsevier, 1985-02-01)
A method for simulation of inhomogeneously broadened EPR of metallo-proteins based on recent theoretical advances is surveyed critically in terms of efficiency and accuracy. From the quality of the experimental spectrum, ...
Diffusion imaging for evaluation of tumor therapies in preclinical animal models
(Springer-Verlag; ESMRMB, 2004-12)
The increasing development of novel targeted therapies for treating solid tumors has necessitated the development of technology to determine their efficacy in preclinical animal models. One such technology that can ...
A statistical theory for powder EPR in distributed systems
(Elsevier, 1985-02-01)
A statistical interpretation is presented for "g strain," the dominant broadening in the EPR spectra of metallo-proteins. The direct cause of g strain is described by a three-dimensional tensor p, whose principal elements ...
An analysis of g strain in the EPR of two [2Fe---2S] ferredoxins. Evidence for a protein rigidity model
(Elsevier, 1986-10-01)
Replacing current notions of a paramagnetic center in a metalloprotein as a single entity in vivo with the more realistic concept of an ensemble of spin systems, each uniquely disturbed by its own surrounding protein, leads ...
A method of image plane multiplex holography
(Elsevier, 1983-11-15)
A method for making image plane multiplex holograms is described. These exhibit the full 3-D imagery of conventional multiplex holograms, but can be made without the use of coherent light. A similarity to lenticular ...
An image deblurring method using diffraction gratings
(Elsevier, 1981-01-15)
A method of image deblurring is described, in which the restoration filter is derived from Ronchi rulings. Although two-dimensional spatial filtering is used, the method employs a line source, resulting in significant noise ...
Cardiac cine magnetic resonance fingerprinting for combined ejection fraction, T1 and T2 quantification
(Wiley Periodicals, Inc.Springer‐Verlag, 2020-08)
Interferometric gratings with phase correction
(Elsevier, 1974-06)
A technique for producing diffractive optical elements uses holographic methods to incorporate into the recorded fringe pattern a correction factor for the phase defect of the substrate.
Bias circuit instabilities and their effect on the d.c. current-voltage characteristics of double-barrier resonant tunneling diodes
(Elsevier, 1991-02)
Bias circuit stability has important implications for the study and application of double-barrier resonant tunneling structures. Stability criteria for resonant tunneling diodes are investigated for the common bias circuit ...
