Approaches to large-scale structures

Current Opinion in Structural Biology, 1995
Quantitative three-dimensional (3D) maps of large-scale structures can now be routinely obtained by the use of high- or intermediate-voltage electron tomography. The recent 3D reconstructions of the mitochondrion and the Golgi apparatus highlight both the potential and the shortcomings of this technique.

Organizing large structural modelbases

IEEE Transactions on Pattern Analysis and Machine Intelligence, 1995
Presents a hierarchically structured approach to organizing large structural modelbases using an information theoretic criterion. Objects (patterns) are modeled in the form of random parametric structural descriptions (RPSDs), an extension of the parametric structural description graph-theoretic formalism.

Structural Principles From Large RNAs

Annual Review of Biophysics, 2008
Since the year 2000 a number of large RNA three-dimensional structures have been determined by X-ray crystallography. Structures composed of more than 100 nucleotide residues include the signal recognition particle RNA, group I intron, the GlmS ribozyme, RNAseP RNA, and ribosomal RNAs from Haloarcula morismortui, Escherichia coli, Thermus thermophilus,

Large scale structural synthesis

Finite Elements in Analysis and Design, 1985
A general purpose optimization program is coupled to a large scale finite element program to provide an efficient tool for structural synthesis. The resulting interface program may be used to design structures for minimum weight, subject to constraints on stress, displacement, and vibration frequencies.

Structuring Large SETL Programs

1986
In the present chapter we round out our account of the control structures of SETL by describing certain useful facilities not covered in earlier chapters.

Structural robustness of large games [PDF]

, 2006
This short survey discusses recent findings on the robustness of Nash equilibria of strategic games with many semianonymous players. It describes the notion of structural robustness and its general consequences, as well as implications to particular games, such as ones played on the web and market games.

Distant large scale structures

The 9th astrophysics conference: After the dark ages, when galaxies were young (the Universe at 2<Z<5), 1999
The existence of massive virialized objects at high redshifts is not expected in most cosmologies. I discuss the evidence for the existence of massive clusters at z>0.9 and conclude that there is strong evidence that such objects exist at z∼1.2. At larger redshifts the evidence is not conclusive.

Cosmological large scale structure

Physics Reports, 1993
Abstract The interrelated cosmological problems of large scale structure and dark matter are reviewed. Contrary to Willy's initial hopes, it appears that the Big Bang Nucleosynthesis constraint requiring the baryon density to be sub-critical remains valid.

Large scale structure: Interpretation

AIP Conference Proceedings, 2001
Reading meaning in the skies is a time-honored activity; as practiced today, the distribution and motion of matter on large scales, as traced by galaxies, is believed to contain information on the origin of density fluctuations in an early epoch of inflation.
