Effect of block copolymer on the electric field induced morphology of polymer blends
(American Chemical Society: Macromolecules, 1991-12-23)
A Model for correlating flow boiling heat transfer in augmented tubes and compact evaporators
(American Society of Mechanical Engineers, 1991-11)
New modes in a plasma with periodic boundaries: the origin of the dense spectrum
(The American Physical Society, 1991-10-28)
We analyze the new features of the low-frequency (£0 < £Op) modes of wave propagation in a plasma filled,
spatially periodic structure. The spectrum of these modes is drastically modified by the periodic
boundaries in a ...
Gene conversion in the evolution of the human and chimpanzee MHC class I loci.
(Blackwell: Tissue Antigens, 1991-10)
Sixty-five DNA sequences from human and chimpanzee major histocompatibility complex class I loci were searched for statistical evidence of past gene conversion. Twenty-four potential conversions were detected; they were ...
Paracrystal model of the high-temperature lamellar phase of a ternary microemulsion system
(Blackwell Publishing : Journal of Applied Crystallography, 1991-10-01)
Small-angle neutron scattering was used to investigate the microstructure of the high-temperature L-alpha phase in the AOT/water/decane system [AOT = sodium bis(2-ethylhexyl) sulfosuccinate]. The system was modeled as ...
Cp3M3(CO)3 clusters: electrocatalytic isomerization and effect of changes in metal and carbon monoxide bonding mode on electron-transfer properties
(The American Chemical Society: Organometallics, 1991-05)
The electrochemical reduction of three trinuclear complexes of general formula Cp3M3(CO)3 (Cp = n^5-cyclopentadienyl, M = Co or Rh) was studied in nonaqueous solutions. The cobalt complex Cp3CO3(CO)3 (3) is reduced by one ...
Parametric analysis of target/decoy performance
(The International Society for Optical Engineering (SPIE), 1991-04-01)
As infrared sensing technology matures and the development of space-based optical sensors
becomes feasible, interest has grown in protecting both ballistic and orbiting objects from detection by
optical sensors. Such ...
Quantum collapses and revivals in a nonlinear Jaynes-Cummings model
(American Physical Society, 1991-04-01)
We investigate the atomic inversion dynamics when a multilevel atom interacts with a two-mode quantized radiation field in a Raman-type process. By utilizing the rotating-wave approximation and adiabatically eliminating ...
Morphological granulometric analysis of electrophotographic images--size distribution statistics for process control
(The Society of Photo-Instrumentation Engineers (SPIE), 1991-04-01)
Size distributions of particles within a binary image can be generated
by morphological filtering processes known as granulometries.
Granulometries filter the image by structuring elements of ever-increasing
size, the ...
Ancient HLA genes from 7,500-year-old archaeological remains
(Nature Publishing Group: Nature, 1991-02-28)
In the past decade there has been increasing interest in cloning DNA from ancient and preserved tissues1−6. Most studies, however, have focused on mitochondrial or chloroplast genes, present at hundreds to thousands of ...
