چکیده
Fused silica fibers with a dumbbell-shaped diameter profile are proposed to simultaneously achieve low thermal noise and low vertical bounce frequency in an interferometric gravitational wave detector. We present a theoretical analysis of achievable noise spectra. We also survey the sources of dissipation in fused silica fibers. Finally, we apply the model to analyze the influence of welded end pins on Q’s of suspensions. 2002 Published by Elsevier Science B.V. PACS: 04.80.Nn; 95.55.Ym; 43.40.+s; 62.40.+i

L\'evy statistics in coding and non-coding nucleotide sequences
The diffusion entropy analysis measures the scaling of the probability density function (pdf) of the diffusion process generated by time series imagined as a physical source of fluctuations. The pdf scaling exponent, δ, departs in the non-Gaussian case from the scaling exponent HV evaluated by variance based methods. When δ = 1/(3 − 2HV ) Lévy statistics characterizes the time series. With the ...
متن کاملAn optimal Q-state neural network using mutual information
Starting from the mutual information we present a method in order to find a hamiltonian for a fully connected neural network model with an arbitrary, finite number of neuron states, Q. For small initial correlations between the neurons and the patterns it leads to optimal retrieval performance. For binary neurons, Q = 2, and biased patterns we recover the Hopfield model. For three-state neurons...

In this Letter, we present the third kind of Darboux transformation of the classical Boussinesq system, and discuss its relationship with the two basic Darboux transformations. By applying the Darboux transformations, we obtain the solutions of multiple soliton interactions, including overtaking and head-on collisions. 2001 Published by Elsevier Science B.V.
متن کاملSelf-organization of hierarchical structures in nonlocally coupled replicator models
We study a simple replicator model with non-symmetric and nonlocal interactions. Hierarchical structures with prey-predator relations are self-organized from a homogeneous state, induced by the dynamical instability of nonlinear interactions.
متن کاملSum rules of codon usage probabilities
In the crystal basis model of the genetic code, it is deduced that the sum of usage probabilities of the codons with C and A in the third position for the quartets and/or sextets is independent of the biological species for vertebrates. A comparison with experimental data shows that the prediction is satisfied within about 5 %.
