CHIRAL BACKGROUND FOR THE TWO PION EXCHANGE NUCLEAR POTENTIAL: A PARAMETRIZED VERSION

We argue that the minimal chiral background for the two-pion exchange nucleon-nucleon interaction has nowadays a rather firm conceptual basis, which entitles it to become a standard ingredient of any modern potential. In order to facilitate applications, we present a parametrized version of a configuration space potential derived previously. We then use it to assess the phenomenological contents of some existing NN potentials.Comment: REVTEX style, 16 pages, 5 PostScript figures compressed, tarred and uuencode

Evidence of Color Coherence Effects in W+jets Events from ppbar Collisions at sqrt(s) = 1.8 TeV

We report the results of a study of color coherence effects in ppbar collisions based on data collected by the D0 detector during the 1994-1995 run of the Fermilab Tevatron Collider, at a center of mass energy sqrt(s) = 1.8 TeV. Initial-to-final state color interference effects are studied by examining particle distribution patterns in events with a W boson and at least one jet. The data are compared to Monte Carlo simulations with different color coherence implementations and to an analytic modified-leading-logarithm perturbative calculation based on the local parton-hadron duality hypothesis.Comment: 13 pages, 6 figures.

Wnt signalling and cancer stem cells

[Abstract] Intracellular signalling mediated by secreted Wnt proteins is essential for the establishment of cell fates and proper tissue patterning during embryo development and for the regulation of tissue homeostasis and stem cell function in adult tissues. Aberrant activation of Wnt signalling pathways has been directly linked to the genesis of different tumours. Here, the components and molecular mechanisms implicated in the transduction of Wnt signal, along with important results supporting a central role for this signalling pathway in stem cell function regulation and carcinogenesis will be briefly reviewed.Ministerio de Ciencia e Innovación; SAF2008-0060

An introduction to Management of Technology pedagogy (andragogy)

In this introduction we leverage efforts of three professionals involved in the practice and use of MoT education. These professionals each discuss MoT from different perspectives. One is primarily interested in MoT pedagogy from a practitioner point of view. Another is a progenitor of the field. The third is an emergent MoT professor. The fourth and fifth utilize their efforts to focus on the importance of MoT education, and how MoT programs, courses and course materials can be presented to managers and technical professionals using both traditional and emergent methods. 21st century managers and students are either participating in or entering into a marketplace where the effective Management of Technology is key both to their professional development and to the effectiveness of large, small and medium enterprises, entrepreneurial activities, NGO operations, government policies and regional development. The Special Issue editors then provide a view of how the authors incorporated in this Special Issue provide the basis for 21st century MoT pedagogy for lifelong learner
