We discuss the basic principles of self-organization of a finite number of charged particles interacting via the 1/r Coulomb potential in disk geometry. The analysis is based on the cyclic symmetry and periodicity of the Coulomb interaction between particles located on several rings. As a result, a system of equations is derived, which allows us readily to determine with high accuracy the equil...

The introduction of brilliant free-electron lasers enables new pump-probe experiments to characterize warm dense matter states. For instance, a short-pulse optical laser irradiates a liquid hydrogen jet that is subsequently probed with brilliant soft x-ray radiation. The strongly inhomogeneous plasma prepared by the optical laser is characterized with particle-in-cell simulations. The interacti...

Thomson, Besner, and Smilek (2016) propose that performance decrements associated with sustained attention are not consistently the result of a decline in perceptual sensitivity. Thomson et al. (2016) present empirical evidence using a novel, nontraditional vigilance task to support their assumptions. However, in the present rebuttal, we argue that the authors have not only have misinterpreted ...

One of the diagnostic systems critical to the success of the DIII–D tokamak experiment is the Thomson scattering diagnostic. This diagnostic is unique in that it measures local electron temperature and density: 1) at multiple locations within the tokamak plasma; and 2) at different times throughout the plasma duration. Thomson “raw” data are digitized signals of scattered light, measured at dif...

Existence of a weak solution is established for the initial-boundary value problem for the system ff-iut-div(O(u)7u)+r(u)a(u)TuTv=a(u)]Tvl2,div(a(u)Vv)=O. The question of uniqueness is also considered in some special cases.

A new species, Demonax proculscuti Li, Tian & Chen, sp. nov. (Coleoptera: Cerambycidae: Cerambycinae), is described from Yunnan Province, Southwest China. A key to 13 species of Demonax from China is presented.

The primary types of Onciderini Thomson, 1860 deposited at The Natural History Museum (BMNH), London, United Kingdom, are catalogued and illustrated. Data on the original combination, current name, and type locality are verified and presented. There are 39 primary types of Onciderini including 11 in Oncideres Lacordaire, 1830; and three each in Hesycha Fairmaire & Germain, 1859; Hypselomus Pert...

This report describes a boy with Rothmund-Thomson syndrome associated with trisomy 8 mosaicism. The patient presented with typical features of Rothmund-Thomson syndrome but some of the features often seen in trisomy 8 mosaics were also observed in him. The possibility that the two disorders might share a common pathogenesis is postulated.
