Selection models are appropriate when the probability that a potential datum enters the sample is a nondecreasing function of the numeric value of the datum. It is rarely justiiable to model this function, called the weight function, with a speciic parametric form, but is appealing to model with a nonparametric prior centered around a parametric form. The Bayesian analysis with Dirichlet proces...

We shall deduce some special regularity properties of solutions to the IVP associated to the Benjamin-Ono equation. Mainly, for datum u0 ∈ H3/2(R) whose restriction belongs to Hm((b,∞)) for some m ∈ Z+, m≥ 2, and b ∈ R we shall prove that the restriction of the corresponding solution u(·, t) belongs to Hm((β ,∞)) for any β ∈R and any t > 0. Therefore, this type of regularity of the datum travel...

T he North American Datum comprises a network of more than 250,000 control points (survey monuments) covering the US, Canada, Mexico, Central America, Greenland, and the Caribbean islands. This network provides a means of accomplishing very accurate horizontal positioning, both on land and offshore. The last major adjustment of this system of control points resulted in the geodetic reference sy...

Force-based ligand detection is a promising method to characterize molecular complexes label-free at physiological conditions. Because conventional implementations of this technique, e.g., based on atomic force microscopy or optical traps, are low-throughput and require extremely sensitive and sophisticated equipment, this approach has to date found only limited application. We present a low-co...

We propose a time discretization of the Navier-Stokes equations inspired by the theory of gradient flows. This discretization produces Leray/Hopf solutions in any dimension and suitable solutions in dimension 3. We also show that in dimension 3 and for initial datum in H, the scheme converges to strong solutions in some interval [0, T ) and, if the datum satisfies the classical smallness condit...

Automatic writer identification and writer verification has recently received significant attention in the field of historical analysis. In this work a short overview of current approaches for writer identification is given. Current state-of-the-art results on contemporary data are related to different approaches for writer verification on a small dataset of datum lines extracted from papal cha...

With coasts that form three >1700 km arms which spiral outward from a point near Kodiak Island, Alaska provides a large-scale site for the study of the relationship between geodesy and sea level. The surface of a static, uniform ocean will follow an equipotential, orthometric surface. Long lived geostrophic currents or prevailing winds result in localized and large scale variations between its ...
