    Background: Small mammals are important reservoirs for pathogens in military conflicts and peacekeeping operations all over the world. This study investigates the rodent communities in three military bases in Northern Afghanistan. Small mammals were collected in this conflict zone as part of Army pest control measures from 2009 to 2012 and identified phenotypically as well as by molecular biological methods. Results: The analysis of the collected small mammals showed that their communities are heavily dominated by the house mouse Mus musculus and to a lesser extent Cricetulus migratorius and Meriones libycus. The origin of M. musculus specimens was analyzed by DNA sequencing of the mitochondrial cytochrome b gene and D-loop sequences. All animals tested belonged to the Mus musculus musculus subspecies indigenous to Afghanistan. The results were supported by detection of two nucleotide exchanges in the DNA polymerase gene of Mus musculus Rhadinovirus 1 (MmusRHV1), a herpesvirus, which is specific for all gene sequences from Afghan house mice, but absent in the MmusRHV1 sequences of German and British house mice. Studies of astrovirus RNA polymerase gene sequences did not yield sufficient resolution power for a similarly conclusive result. Conclusions: House mouse populations in military camps in Northern Afghanistan are indigenous and have not been imported from Europe. Nucleotide sequence polymorphisms in MmusRHV1 DNA polymerase gene might be used as an additional phylogeographic marker for house mice.

    This paper addresses the problem of calibration for antenna arrays with multi-port polarimetric elements. Model-based array signal processing techniques require an accurate model of the complex array response and model errors can, for example, cause significant systematic direction finding errors. Modeling the response of polarimetric antenna arrays can be particularly challenging due to cross-polarization and mutual coupling effects in the multi-port antenna elements. This work proposes a new calibration technique for polarimetric antenna arrays using neural networks that learn any mismatches between the modeled and the actual array response. The technique is evaluated based on the measured response of a five-element dual-polarized antenna array and outperforms conventional calibration techniques like mutual coupling calibration or local polynomial approximation. Its performance is studied exemplarily for the direction finding problem.

    Authors: Hahlbohm, Dörte;

    Das zentrale Interesse der Arbeit ist es, zum einen die Anforderungen an ein effektives Kontrollregime für biologische Waffen (BW) zu erarbeiten und zum anderen die Erfolgsbedingungen eines solchen Regimes zu ermitteln, um so Aussagen über die Chancen einer effektiven Kontrolle biologischer Waffen machen zu können. Angesichts der Tatsache, daß im Bereich der Massenvernichtungswaffen (nukleare, biologische und chemische Waffen) die Proliferation der chemischen und der nuklearen Waffen durch effektive Regime kontrolliert wird, die Kontrollmechanismen im Bereich der biologischen Waffen jedoch nach wie vor unzureichend sind und die laufenden Verhandlungen zur Stärkung der bestehenden BW-Kontrolle nur sehr zögerlich vorangehen, wurde die Untersuchung vergleichend angelegt. Dadurch können die Erfahrungen mit dem Zustandekommen und der Effektivität der bereits bestehenden zwei Kontrollregime für die Analyse der Realisierungschancen einer effektiven BW-Kontrolle genutzt werden. Kapitel 1 befaßt sich mit den spezifischen Eigenschaften biologischer Waffen sowie mit der biotechnologischen Entwicklung der vergangenen Jahre und den daraus resultierenden möglichen Implikationen für die Weiterentwicklung BW. In Kapitel 2 werden die Kriterien für ein effektives Kontrollregime erarbeitet und operationalisiert. In Kapitel 3 werden sechs Hypothesen über die Ursachen für den schleppenden Verhandlungsverlauf zur Stärkung der BW-Kontrolle entwickelt. Anschließend wird die Methode der vergleichenden Hypothesenprüfung erläutert. In Kapitel 4 wird eine umfassende empirische Bestandsaufnahme der drei Fälle vorgenommen, die anhand der in Kapitel 2 entwickelten Effektivitätskriterien strukturiert wird. Die Auswertung belegt die der Untersuchung zugrundegelegte Annahme, daß das nukleare und das chemische Kontrollregime als ausreichend effektiv betrachtet werden können, bei der Kontrolle der biologischen Waffen jedoch noch einige Schwachstellen zu bemängeln sind. In Kapitel 5 werden die bisherigen Bemühungen um die Effektivierung der Kontrolle biologischer Waffen darauf hin untersucht, ob sie bislang dazu beitragen konnten, die in Kapitel 4 festgestellten Mängel zu beseitigen. In Kapitel 6 erfolgt die vergleichende Überprüfung der Hypothesen. Ziel ist es dabei sowohl Aussagen über die Relevanz der Hypothesen machen zu können, als auch die Chancen einer effektiven Kontrolle biologischer Waffen bewerten zu können.

  • The novel aerodynamic window with a pump cavity and a supersonic gas jet described in /1/ shows considerable improvements in operation performances such as shock-free operation range, reduction of the mass flow rate as well as operation stability. Its optical quality at different operation states has been investigated firstly with the schlieren method. Then the window was combined with a 5 kW CO2 laser using an unstable resonator. The influences of the window on the laser beam quality at different operation states have been investigated. The results will be presented in this paper.

  • In order to investigate size effects occurring in the miniaturization of turning processes a complete dimensional analysis using a materials model for high-speed deformation was performed. The derived dimensionless similarity numbers were used to guide the parameter variation in simplified two-dimensional finite-element simulations for orthogonal cutting. The rate-depended material model leads to size effects like an increase of the specific cutting force while reducing the cutting depth. Acounter-intuitive dependence of the cutting force on cutting velocity is explained using a shear-plane model. The derived dependencies on single input parameters are used to predict output values while simultaneously changing several input parameters.

Anschließend wird die Methode der vergleichenden Hypothesenprüfung erläutert. In Kapitel 4 wird eine umfassende empirische Bestandsaufnahme der drei Fälle vorgenommen, die anhand der in Kapitel 2 entwickelten Effektivitätskriterien strukturiert wird. Die Auswertung belegt die der Untersuchung zugrundegelegte Annahme, daß das nukleare und das chemische Kontrollregime als ausreichend effektiv betrachtet werden können, bei der Kontrolle der biologischen Waffen jedoch noch einige Schwachstellen zu bemängeln sind. In Kapitel 5 werden die bisherigen Bemühungen um die Effektivierung der Kontrolle biologischer Waffen darauf hin untersucht, ob sie bislang dazu beitragen konnten, die in Kapitel 4 festgestellten Mängel zu beseitigen. In Kapitel 6 erfolgt die vergleichende Überprüfung der Hypothesen. Ziel ist es dabei sowohl Aussagen über die Relevanz der Hypothesen machen zu können, als auch die Chancen einer effektiven Kontrolle biologischer Waffen bewerten zu können.

  • The novel aerodynamic window with a pump cavity and a supersonic gas jet described in /1/ shows considerable improvements in operation performances such as shock-free operation range, reduction of the mass flow rate as well as operation stability. Its optical quality at different operation states has been investigated firstly with the schlieren method. Then the window was combined with a 5 kW CO2 laser using an unstable resonator. The influences of the window on the laser beam quality at different operation states have been investigated. The results will be presented in this paper.

  • In order to investigate size effects occurring in the miniaturization of turning processes a complete dimensional analysis using a materials model for high-speed deformation was performed. The derived dimensionless similarity numbers were used to guide the parameter variation in simplified two-dimensional finite-element simulations for orthogonal cutting. The rate-depended material model leads to size effects like an increase of the specific cutting force while reducing the cutting depth. Acounter-intuitive dependence of the cutting force on cutting velocity is explained using a shear-plane model. The derived dependencies on single input parameters are used to predict output values while simultaneously changing several input parameters.
