We study some properties of random walks perturbed at extrema, which are generalizations of the walks considered, e.g., by Davis (1999) and Tth (1996). This process can also be viewed as a version of an excited random walk, recently studied by many authors. We obtain several properties related to the range of the process with infinite memory and prove the strong law, the central limit theorem, and

While economic issues are not usually much debated in theology, three recent mission documents (The Cape Town Commitment, Together Towards Life and Evangelii Gaudium) have directly addressed them, criticising globalised capitalism more or less sharply and explicitly. However, all three lack transparency in that possible analysis which might provide foundation for the statements made is not visible

The equations of motion for a constrained multibody system are derived from a continuum mechanical point of view. This will allow for the presence of rigid, as well as deformable, parts in the multibody system together with kinematical constraints. The approach leads to the classical Lagrange-d'Alembert equations of motion under constraint conditions. The generalized forces appearing in the equati

We present an analytical algorithm for deriving the shapes of the deformable mirrors to be used for multiconjugate adaptive correction on a large telescope. The algorithm is optimal in the limit where the overlap of the wave-front contributions from relevant atmospheric layers probed by the guide stars is close to the size of the pupil. The fundamental principle for correction is based on a minimi

Despite the fact that the origin of human immunodeficiency virus (HIV) being a contamination and a mutation originating from primates is well-documented alternative narratives are often being heard ofespecially in sub-Saharan Africa. One such narrative is about HIV being man-made in a military laboratory in the United States. In this article, it is shown how this narrative was fabricated by the in

Examination of the interethnic tensions in the Republic of Macedonia and the political dynamics they set in motion

The changing structure of the Swedish university system has shaped its corps of university teachers. The analytical device used to demonstrate this connection is the changing social functions of Swedish universities which serve as the lens through which we understand this change. We argue for five successive and historically added layers of functions: the training of church officials, state functi
