Figure 1. 3-D Doppler imaging reconstruction of the Fe distribution in the atmosphere of magnetic Ap star θ Aur (HD 40312)
Figure 2. Theoretical and observed IS for roAp stars. Positions of the roAp stars are shown by filled circles with size proportional to parallax value, while filled squares indicate positions of the nine luminous Ap stars in which pulsations were not found.
Figure 3. Theoretical (black line) and observed (open circles) pulsational RV phase and amplitude distributions in the atmosphere of the roAp star HD 24712.
Figure 4. Observed equivalent widths of the Pr II (circles) and Pr III (diamonds) lines in HD 24712 compared with the theoretical non-LTE (filled symbols) and LTE (open symbols) equivalent widths for the uniform Pr distribution with [Pr/H] = 3 (left panel)

In Section 3 we introduce the modular symbols formalism extended to subgroups of finite index in Hecke triangle groups, and give a description in terms of Manin symbols.. An

In this paper, we develop a new mutation testing technique called Interlocutory Mutation Testing (IMT) that mitigates the equiv- alent mutant problem in the presence of

The headscarf at school, the burka in the street, the mosque in the city, and the minarets in the landscape indicate the presence of Muslim actors in daily life (sometimes with

The differences are that : (i) the cross section d a , or da,, is replaced by the real photon cross section ; (ii) in evaluating this cross section, the kinematics

Like Feature 9, the possible plinth of a calvary dated from 1680 found at La Cremaillere, and Feature 1131, the plinth of a cross uncovered in 2007 at Dos-de-Cheval, crosses

Having motivated that mathematical semantic markup languages can help to make semantic wikis aware of mathematics, we showed how the OpenMath content dictionary language was
