Computersimulation in der Astrophysik
Unser Wissen über die Struktur des Kosmos und die darin enthaltenen Objekte stammt aus der sorgfältigen Analyse der einfallenden elektromagnetischen Strahlung, verbunden mit e iner theoretischen Modellierung im Rahmen der von uns erforschten Naturgesetze. Die Beobachtungen erstrecken sich dabei heute vom Radiowellenbereich über den Infrarot-, den optischen, den Röntgenbereich bis hin zum Höchst...
متن کاملEinführung in die Astrophysik der Mikroquasare Habilitationsschrift
1 FOREWORD This review was written to fulfill the requirements for the " Habilitation " procedure at the University of Bonn. It summarizes a part of the research I have conducted over the last years in the field of microquasars and it should stimulate students' interest in this challenging and fascinating topic. The astronomical methods used in the range of gamma-rays, X-rays, optical and radio...
متن کاملHamburger polyomaviruses
Epidemiological studies have suggested that consumption of beef may correlate with an increased risk of colorectal cancer. One hypothesis to explain this proposed link might be the presence of a carcinogenic infectious agent capable of withstanding cooking. Polyomaviruses are a ubiquitous family of thermostable non-enveloped DNA viruses that are known to be carcinogenic. Using virion enrichment...
متن کاملThe hamburger theorem
We generalize the ham sandwich theorem to d+1 measures in R as follows. Let μ1, μ2, . . . , μd+1 be absolutely continuous finite Borel measures on R. Let ωi = μi(R ) for i ∈ [d + 1], ω = min{ωi; i ∈ [d + 1]} and assume that ∑d+1 j=1 ωj = 1. Assume that ωi ≤ 1/d for every i ∈ [d + 1]. Then there exists a hyperplane h such that each open halfspace H defined by h satisfies μi(H) ≤ ( ∑d+1 j=1 μj(H)...
متن کاملViktor Hamburger (1900-2001)
Viktor Hamburger [5] was an embryologist who focused on neural development [6]. His scientific career stretched from the early 1920s as a student of Hans Spemann [7] to the late 1980s at Washington University [8] resolving the role of nerve growth factor [9] in the life of neurons. Hamburger is noted for his systematic approach to science and a strict attention to detail. Throughout his life he...
