[1] Formation and evolution of cirrostratus in response to weak, uniform, and constant synoptic forcing is simulated using a one-dimensional numerical model with explicit microphysics, in which the particle size distribution in each grid box is fully resolved. A series of tests of the model response to nucleation modes (homogeneous-freezingonly/heterogeneous nucleation) and heterogeneous nuclea...

Thue [14] showed that there exist arbitrarily long square-free strings over an alphabet of three symbols (not true for two symbols). An open problem was posed in [7], which is a generalization of Thue’s original result: given an alphabet list L = L1, . . . , Ln, where |Li| = 3, is it always possible to find a square-free string, w = w1w2 . . .wn, where wi ∈ Li? In this paper we show that square...

great importance. Realizing all this and being entitled to reasonable satisfaction with their results, general practitioners rarely bother to get a specimen investigated. They hardly ever delay treatment until a laboratory report is forthcoming, though in a strictly clinical sense this is what they might be expected to do. Before the advent of the siulpjionamides majority of the cases was treat...

Forced alignment both for words and phones is a challenging and interesting task for automatic speech processing systems because the difficulties introduced by natural speech are many and hard to deal with. Furthermore, forced alignment approaches have been tested on Italian just in a few studies. In this task, the main goal was to evaluate the performance offered by the proposed systems on Ita...

Given a saddle fixed point of a surface diffeomorphism, its stable and unstable curves W S and W U often form a homoclinic tangle. Given such a tangle, we use topological methods to find periodic points of the diffeomorphism, using only a subset of the tangle with finitely many points of intersection, which we call a trellis. We typically obtain exponential growth of periodic orbits, symbolic d...

Mock Walker cells driven by weak sea surface temperature (SST) forcing are studied using planetary-scale cloud system–resolving simulations and a simplified framework that represents convection with its linear response functions and parameterizes the large-scale flow based on the gravity wave equation. For sinusoidal SST forcings of the same amplitude, as the horizontal domain size increases, t...

This paper develops a Lyapunov approach to the analysis of input–output characteristics for systems under the excitation of a class of oscillatory inputs. Apart from sinusoidal signals, the class of oscillatory inputs include multi-tone signals and periodic signals which can be described as the output of an autonomous system. The Lyapunov approach is developed for linear systems, homogeneous sy...

Introduction It is well known that air entrainment sets the ultimate limit to coating speeds. It is also known that air entrainment can be postponed to higher line speeds by manipulating coating flows to generate what has been termed ‘hydrodynamic assist’ [1]. There is increasing evidence that the benefit is associated with geometric or hydrodynamic confinement of the moving contact line [1-3]....
