We arrange the loopwise perturbation theory for the critical viscosity exponent xη, which happens to be very small, as a power series in xη itself and argue that the effect of loops beyond two is negligible. We claim that the critical viscosity exponent should be very closely approximated by xη = 8 15π (1 + 8 3π ) ≃ 0.0685. PACS number(s):64.60Ht

Cavitation bubbles in acoustic resonators are observed to arrange in branch-like patterns. We give a brief review of the anatomy of such structures and outline an approach for simulation by individual, moving bubbles. This particle model can reproduce an experimentally observed transition between different structure types in a rectangular resonator cell.

A homochiral diamond framework was obtained by using a secondary building unit (SBU) comprising an oxo-cluster containing 4Fe(III) and 3Mn(II) ions supported by Sb(3)O tartrate scaffolds. A fully protonated tetratopic cation, tetrakis(4-pyridyloxymethylene)methane (TPOM), acts as a template to arrange the clusters on a diamond lattice.

In the title compound, C(10)H(12)N(2)O(6)S, the nitro group is twisted slightly out of the plane of the aromatic ring, forming a dihedral angle of 20.79 (1)°. In the crystal, the mol-ecules arrange themselves as a chain along the a axis through inter-molecular C-H⋯O inter-actions.

Smart photo sticking is a novel strategy to automatically arrange a collection of photos in a pleasant collage. The proposed approach improves previous solutions both considering a self-adaptive image cropping algorithm, exploiting visual and semantic information, and introducing an optimization process based on a genetic algorithm. Preliminary results confirm the effectiveness of the proposed ...

With IP Multicast not gaining wide acceptance, researchers turned to alternative multicast mechanisms like application level multicast. Application Level Multicast protocols arrange the participating hosts into an overlay topology; maintain it and distribute data packets over that topology. In this paper, we propose a new application level multicast protocol, describe few well-known protocols, ...

It has long been debated whether eye movements play a functional role in visual mental imagery. A recent paper by Laeng and Teodorescu presents new evidence that eye movements are stored as a spatial index that is used to arrange the component parts correctly when mental images are generated.

but the most concrete, for he must also proceed from the known to the less known. He must arrange the presentation so that a puzzle or problem is proposed and suggested to the pupil, add his curiosity aroused to endeavor to

A new method to design wavelet networks using genetic algorithms is proposed. Designing wavelet networks is regarded as a combinatorial optimization problem to arrange the windows of wavelets and then genetic algorithms are used to derive their optimal arrangement. The effectiveness of the proposed method is verified through computer experiments.

The discretely diffracting aperiodic crystals termed quasicrystals, discovered at NBS in the early 1980s, have led to much interdisciplinary activity involving mainly materials science, physics, mathematics, and crystallography. It led to a new understanding of how atoms can arrange themselves, the role of periodicity in nature, and has created a new branch of crystallography.
