76 Stringfellow, Gerald B.Surface photoabsorption transients and ordering in GaInPHeterostructures and quantum wells can be produced in GaInP without changing the solid composition by simply varying the order parameter. Since CuPt ordering reduces the band-gap energy, changes in the order parameter induced by changes in growth conditions result in heterostructures with band-ga...Order parameters; Quantum wells; P-dimers1998-03-15
77 Mattis, Daniel C.Theory of ferromagnetism in carbon foamAn explanation is proposed for spontaneous magnetism in the material, "carbon nanofoam," in terms of random ferrimagnetism. Wherever a carbon nanotube branches out, an electron trap is created at the junction. Electrons occupying neighboring junctions align their spins antiparallel.Carbon foam; Nanotubes; Nanofoam2005-04
78 Beckerle, Mary C.LIM proteins in actin cytoskeleton mechanoresponseThe actin cytoskeleton assembles into branched networks or bundles to generate mechanical force for critical cellular processes such as establishment of polarity, adhesion, and migration.

79 Mcpherson, Brian JamesDirect simulation of fluid-solid mechanics in porous media using the discrete element and lattice-Boltzmann methodsA detailed understanding of the coupling between fluid and solid mechanics is important for understanding many processes in Earth sciences. Numerical models are a popular means for exploring these processes, but most models do not adequately handle all aspects of this coupling. This paper presents ...2007
80 Sperry, John S.Evaluation of Murray's law in Psilotum nudum (Psilotaceae), an analogue of ancestral vascular plantsPrevious work has shown that the xylem of seed plants follows Murray's law when conduits do not provide structural support to the plant. Here, compliance with Murray's law was tested in the stem photosynthesizer Psilotum nudum, a seedless vascular plant. Psilotum nudum was chosen because the central...Conduit furcation number; hydraulic architecture; Murray's law2005

87 Brinkman, Paul T.Options for cost analysisMany kinds of cost analysis are possible. Indeed, given the variety of purposes, methods, and types of cost, the number of permutations is virtually unlimited. In broad terms, one can disaggregate the universe of cost studies by distinguishing whether their primary purpose is to determine costs or t...Budget; Allocation1989
