IceCube
A. Karle,for the IceCube Collaboration
Physics , 2010,
Abstract: IceCube is a 1 km^3 neutrino telescope currently under construction at the South Pole. The detector will consist of 5160 optical sensors deployed at depths between 1450 m and 2450 m in clear Antarctic ice distributed over 86 strings. An air shower array covering a surface area of 1 km2 above the in-ice detector will measure cosmic ray air showers in the energy range from 300 TeV to above 1 EeV. The detector is designed to detect neutrinos of all flavors: electron-, muon-, and tau-neutrinos. With 59 strings in operation in 2009, construction is 67% complete. Based on data taken to date, the observatory meets its design goals. Selected results will be presented.
IceCube - the next generation neutrino telescope at the South Pole
A. Karle,for the IceCube Collaboration
Physics , 2002, DOI: 10.1016/S0920-5632(03)01337-9
Abstract: IceCube is a large neutrino telescope of the next generation to be constructed in the Antarctic Ice Sheet near the South Pole. We present the conceptual design and the sensitivity of the IceCube detector to predicted fluxes of neutrinos, both atmospheric and extra-terrestrial. A complete simulation of the detector design has been used to study the detector's capability to search for neutrinos from sources such as active galaxies, and gamma-ray bursts.
IceCube - status and recent results
A. Karle,for the IceCube Collaboration
Physics , 2014,
Abstract: In May 2011, the IceCube neutrino observatory with one cubic kilometer instrumented volume started full operation with 5160 sensors on 86 strings and 324 sensors on 162 IceTop detectors. The fine-tuning of operation and calibration of the detector is still in progress while a very high uptime of well above $98\%$ is obtained. New analysis techniques rely on veto techniques for enhanced rejection of atmospheric muon and neutrino backgrounds. We will give an overview of recent results including the techniques of searching for starting tracks and some comments on the reported evidence of astrophysical neutrinos at energies above 30 TeV.
Moon Shadow Observation by IceCube
D. J. Boersma,L. Gladstone,A. Karle,for the IceCube Collaboration
Physics , 2010,
Abstract: In the absence of an astrophysical standard candle, IceCube can study the deficit of cosmic rays from the direction of the Moon. The observation of this "Moon shadow" in the downgoing muon flux is an experimental verification of the absolute pointing accuracy and the angular resolution of the detector with respect to energetic muons passing through. The Moon shadow has been observed in the 40-string configuration of IceCube. This is the first stage of IceCube in which a Moon shadow analysis has been successful. Method, results, and some systematic error studies will be discussed.

Abstract: ket to paper this report defines a set of international standards in basic (undergraduate) medical education, structured according to nine areas with a total of 38 criteria. standards are specified for each criterion, using two levels of attainment. the first set defines the base line or minimal or essential requirements to medical schools. the second set deals with the dimension of quality development of medical schools and their educational programmes. the use of such a categorization of standards means that medical schools at various stages of development and with different educational traditions, socio-economic and cultural conditions can use the system of standards at a level appropriate to them. standards should not lead to uniformity but function as a lever for change and reform. the set of standards might best be used in quality assessment studies of medical schools based on a combination of institutional self-evaluation and peer review. to reach the implementation phase, the weme task force is currently considering the production of a manual or practical guide for data collection and evaluation of medical schools on the basis of these standards. by publicizing the report, the world federation for medical education invites medical educators and institutions, organizations and authorities engaged in basic medical education to discuss and comment on both the proposed set of standards and the issue of implementing such standards as tools in assessment of medical schools.

Abstract:
Where does European Medical Education tend to in the future? [Wohin entwickelt sich die Europ ische Medizinische Ausbildung?]
Karle, Hans
GMS Zeitschrift für Medizinische Ausbildung , 2006,
Abstract: [english] Medical education is presently unveiling trends, which also dominate other fields of higher education. Within the framework of internationalisation and globalisation, and driven by developments in information and communication technology and the pronounced migration of medical doctors, one has observed consequences such as commercialisation and privatisation. This, in turn, has engendered a quality assurance reaction with focus on standardisation and accreditation. The Bologna Declaration and Process can be seen as part of this new quality concern, but also raises problems for medical education regarding the two-cycle (bachelor and master degrees) system. Standard setting in medical education in Europe took its start with the EU Medical Directive, which has essentially not been changed in 30 years. The increasing internationalisation of medical education, which shows a number of innovative trends, but which also unveils many problems and challenges, emphasises the role of the WFME Global Standards Programme launched in 1997. The Trilogy of Global Standards, covering the continuum of medical education, has been adopted in all parts of the world. The Standards for Basic Medical Education are used in reform programmes in many medical schools and are now also being incorporated in definition of national accreditation standards. This development has recently been strengthened in the WHO/WFME Strategic Partnership to Improve Medical Education. One practical result of this collaboration was the development of WHO/WFME Guidelines for Accreditation of Basic Medical Education. A Task Force under the new EU Thematic Network MEDINE is now working with definition of European accreditation standards using the WFME Global Standards as a template. The immediate perspective will be establishment of national accreditation systems in the European region and there is probably no need at the moment for a common accreditation system in Europe.

Abstract: Claves del informe Este informe define un conjunto de estándares internacionales para la ense anza médica de pregrado, estructurados en torno a 9 áreas, con un total de 38 criterios. Se han especificado estándares para cada criterio, aplicando 2 niveles de consecución. En el primer grupo se define la base o requerimientos mínimos o esenciales para la facultades de medicina. El segundo grupo se ocupa de la dimensión del desarrollo de la calidad de las facultades de medicina y sus programas educativos. El uso de esta clasificación de estándares significa que las facultades de medicina, en diversos estadios de desarrollo, con diferentes tradiciones educativas, condiciones socioeconómicas y culturales, pueden aplicar el sistema de estándares a un nivel adecuado para cada facultad. Los estándares no deberían conducir a la uniformidad, sino a actuar como punto de apoyo para el cambio y la reforma. El conjunto de estándares podría utilizarse de manera óptima para los análisis de la evaluación de la calidad de las facultades de medicina, basándose en una combinación entre la autoevaluación institucional y la revisión entre iguales (peer review). Para alcanzar la fase de implementación, la Task Force de la WFME está considerando actualmente la elaboración de un manual o guía práctica para la recogida de datos y la evaluación de las facultades de medicina sobre la base de estos estándares. Con la publicación de este informe, la World Federation for Medical Education (Federación Mundial para la Educación Médica) invita a los educadores y a las instituciones, así como a las organizaciones y autoridades que participan en la educación médica, a comentar y debatir tanto el conjunto de estándares propuestos como la cuestión de la puesta en práctica de dichos estándares como instrumento para la evaluación de las facultades de medicina.

Neutrino Astronomy - A Review of Future Experiments
Albrecht Karle
Physics , 2012, DOI: 10.1016/j.nuclphysbps.2013.04.034
Abstract: Current generation neutrino telescopes cover an energy range from about 10 GeV to beyond $10^9$ GeV. IceCube sets the scale for future experiments to make improvements. Strategies for future upgrades will be discussed in three energy ranges. At the low-energy end, an infill detector to IceCube's DeepCore would add sensitivity in the energy range from a few to a few tens of GeV with the primary goal of measuring the neutrino mass hierarchy. In the central energy range of classical optical neutrino telescopes, next generation detectors are being pursued in the Mediterranean and at Lake Baikal. The KM3NeT detector in its full scale would establish a substantial increase in sensitivity over IceCube. At the highest energies, radio detectors in ice are among the most promising and pursued technologies to increase exposure at $10^9$ GeV by more than an order of magnitude compared to IceCube.
