چکیده

As a symptom of evolution, human beings are always trying to better understand current and past events so we are able to foresee future situations and develop new tools or methods. The data registered over millions of years is an impressive source of information that, for instance, help us to model earth dynamics or to make climatic predictions. We find the largest and oldest record in the oceans. Palaeoceanographers, in order to monitor and make predictions, need to manipulate, integrate and analyse paleo time-series that are obtained from a number of independent techniques and instruments (such as ocean drilling, ocean tracers, AMC 14C datings, astronomic curves, etc.), which, moreover, are usually produced by different researchers and/or laboratories. The result is a collection of datasets with unequal age precision. In the last years, several tools have been developed to allow best management and analysis of these data. The main available tools are represented by databases (Dbase, Access, Foxpro, Oracle, etc.), spreadsheets (Lotus, Excel, etc.), statistical packages (Axum, Data Desk, S-Plus, SPSS) and graphical and/or image tools (Statgraphics, CorelDraw, and many more).This worsens the situation since, at present, there is not an assembly of integrated tools that allows the palaeontologists to perform a study without having to use applications of different natures, which are of general purpose and, usually, expensive and platform-dependent. Some freeware tools have appeared in the last few years that were designed for the field of paleoclimatology (AnalySeries [1]) or paleontology (PAST, [2]), which include many commonly used functions, but they are rather limited to a one-by-one analysis, are one-platform-only and the results usually need to be exported to other tools for further analysis or make them more legible. The goal of this project was to develop a tailor-made, platform-independent, full featured tool that could simplify the palaeocenographers work, being used during the whole process: from the beginning, merging and correlating different datasets, continuing with interactive analyses, to the end, plotting the results.

Gains from diversification on convex combinations: A majorization and stochastic dominance approach

By incorporating both majorization theory and stochastic dominance theory, this paper presents a general theory and a unifying framework for determining the diversification preferences of risk-averse investors and conditions under which they would unanimously judge a particular asset to be superior. In particular, we develop a theory for comparing the preferences of different convex combination...

Improved immunogenicity of tetanus toxoid by Brucella abortus S19 LPS adjuvant.

BACKGROUND Adjuvants are used to increase the immunogenicity of new generation vaccines, especially those based on recombinant proteins. Despite immunostimulatory properties, the use of bacterial lipopolysaccharide (LPS) as an adjuvant has been hampered due to its toxicity and pyrogenicity. Brucella abortus LPS is less toxic and has no pyrogenic properties compared to LPS from other gram negati...

Steady electrodiffusion in hydrogel-colloid composites: macroscale properties from microscale electrokinetics.

A rigorous microscale electrokinetic model for hydrogel-colloid composites is adopted to compute macroscale profiles of electrolyte concentration, electrostatic potential, and hydrostatic pressure across membranes that separate electrolytes with different concentrations. The membranes are uncharged polymeric hydrogels in which charged spherical colloidal particles are immobilized and randomly d...

Perturbative Analysis of Dynamical Localisation

In this paper we extend previous results on convergent perturbative solutions of the Schrödinger equation of a class of periodically timedependent two-level systems. The situation treated here is particularly suited for the investigation of two-level systems exhibiting the phenomenon of (approximate) dynamical localisation. We also present a convergent perturbative expansion for the secular fre...

Collinear contextual suppression

The context of a target can modulate behavioral as well as neural responses to that target. For example, target processing can be suppressed by iso-oriented surrounds whereas it can be facilitated by collinear contextual elements. Here, we present experiments in which collinear elements exert strong suppression whereas iso-oriented contextual surrounds yield no contextual modulation--contrary t...
