Beschreibung: Author(s): C. Sun, D. S. Robin, C. Steier, and G. Portmann Pseudosingle-bunch kick-and-cancel (PSB-KAC) is a new operational mode at the Advanced Light Source of Lawrence Berkeley National Laboratory that provides full timing and repetition rate control for single x-ray pulse users while being fully transparent to other users of synchrotron radiation light.… [Phys.

Beschreibung: Author(s): Wei Zhong, Gerard T. Barkema, Debabrata Panja, and Robin C. Ball We study the scalar one-component two-dimensional (2D) ϕ 4 model by computer simulations, with local Metropolis moves. The equilibrium exponents of this model are well established, e.g., for the 2D ϕ 4 model γ = 1.75 and ν = 1 . The model has also been conjectured to belong to the Ising universality class.... [Phys.

Beschreibung: Author(s): Patrick B. Warren, Robin C. Ball, and Raymond E. Goldstein The problem of how staple yarns transmit tension is addressed within abstract models in which the Amontons-Coulomb friction laws yield a linear programing (LP) problem for the tensions in the fiber elements. We find there is a percolation transition such that above the percolation threshold the tran... [Phys. Rev. Lett. 120, 158001] Published Fri Apr 13, 2018

Beschreibung: Author(s): Wei Zhong, Debabrata Panja, Gerard T. Barkema, and Robin C. Ball We consider the two- (2D) and three-dimensional (3D) Ising models on a square lattice at the critical temperature T c , under Monte Carlo spin flip dynamics. The bulk magnetization and the magnetization of a tagged line in the 2D Ising model, and the bulk magnetization and the magnetization of a tagge... [Phys. Rev.

Beschreibung: The uppermost Cretaceous to early Palaeogene is a period of major deformations of the western part of the Eurasian plate with prominent basin inversions starting from the Coniacian onwards. These deformations occur in a complex geodynamic setting within both the context of the Africa–Eurasia convergence and the North Atlantic opening. While Mesozoic graben inversions have been extensively studied, particularly in Eastern Europe and the North Sea, more gentle deformations that affect thicker crust areas (intracratonic basins and emerged lands) are not as well documented. The objective of this study is to constrain the exact timing, type, and magnitude of the early Palaeogene deformations affecting the intracratonic Paris Basin and to integrate them at the western European scale. Low-amplitude deformations are attempted through a high-resolution reconstitution of its stratigraphic record based on well-dated outcrops and well-dated wells, and a high number of well-logs that are correlated using the “stacking pattern” sequence stratigraphic technique. Two orders of sequences are identified (third and fourth order) and correlated throughout the basin. Basin geometric and palaeogeographic reconstitutions are based on sediment thickness and facies analysis. Two-dimensional accommodation space measurements were taken in order to quantify the magnitude of the deformations. Three phases of deformation were recognized. 1. An intra-Maastrichtian–pre-Thanetian (59 Ma) deformation, with major uplift and erosion of the Cretaceous strata with two sub-periods of deformation: Maastrichtian–pre-middle-Danian and Upper Danian–pre-Thanetian long-wavelength deformations. This period of major deformation is coeval with Upper Cretaceous/pre-Danian compressive deformations linked to the Africa–Eurasia convergence in southern France and with volcanic activity from the North Atlantic to Massif Central and the Rhenish Shield during the Palaeocene. 2. An early Ypresian (55.1–54.3 Ma) medium-wavelength deformation ( ×  10 km), here reported to be a stress rearrangement related to the onset of the North Atlantic opening. 3. An uppermost Ypresian (49.8 Ma) long-wavelength deformation ( ×  100 km), contemporaneous with flexural compressive deformations in the Aquitaine Basin (Pyrenean deformation), and related to the Iberia–Eurasia convergence.
