Biased Cold Dark Matter Theory - Trouble from Rich Clusters
(Univ Chicago Press, 1989-06-15)
Measurement of fracture stress, young's modulus, and intrinsic stress of heavily boron-doped silicon microstructures
(Elsevier, 1989-12-10)
Heavily boron-doped silicon microstructures fabricated using deep-boron diffusions and boron etch-stops have been widely used in a variety of integrated sensors and actuators. For many applications, having knowledge of the ...
Synthesis and regional mouse brain distribution of [11C]Nisoxetine, a norepinephrine uptake inhibitor
(Elsevier, 1989)
Nisoxetine, a selective and high affinity (IC50 = 1 nM) inhibitor of NE reuptake, has been radiolabeled in high specific activity (> 600 Ci/mmol) by the alkylation of the nor-methyl precursor with [11C]CH3I. Synthetic ...
COMMENT: Reply to a comment by R Newton
(IOP Publishing Ltd, 1989-06-01)
Following Newton's comment (see ibid., vol.5, p.437 (1989)), the author points out that: (1) the major contribution of his previous paper (see ibid., vol.4, p.549 (1988)) is the generalised fast Cholesky algorithm, not the ...
Canonical transformations and graph theory
(Elsevier, 1989-07-03)
In the class of symplectic matrices, two infinite subsets are generated by binary spanning trees. For given N, the procedure begins with the complete graph, KN to which N-1 virtual vertices are added in well-defined ways. ...
Reaction between YBa2Cu3O7−x and water
(The American Institute of Physics, 1989-02-01)
Reaction between water at 80 °C and YBa2Cu3O7−x (0.8<x<0.0) is studied using x‐ray absorption fine structure (EXAFS) and x‐ray diffraction (XRD). Oxygen deficient YBa2Cu3O7−x reacts with water and decomposes into BaCO3, ...
Experimental test of the Siberian Snake concept
(The American Institute of Physics, 1989-05-05)
We are now beginning an accelerator physics experiment at the Indiana University Cyclotron Facility (IUCF) proton Cooler Ring, which will be the first experimental test of the Siberian Snake concept for dealing with ...
The elastic energy-momentum tensor in special relativity
(Elsevier, 1989-12)
We consider the standard nonrelativistic theory of a continuous, elastic medium with finite deformations, according to which the elastic energy is a function only of the state of strain, and the elastic stress tensor is ...
Time‐of‐flight spectrometer for an ECR ion source
(The American Institute of Physics, 1989-03)
A time‐of‐flight ion spectrometer using electrostatic grids for ion gating is described. The spectrometer was built to monitor the charge state distribution of endloss ions passing from the midplane region of an ECR‐heated, ...
Ordered shapes in nonequilibrium growth
(Elsevier, 1989-09)
Patterns observed during nonequilibrium growth display complex ordering on many length scales. We focus on ordered patterns which reflect the interplay of microscopic and macroscopic dynamics. The fundamental morphologies ...
