No full text147. Ixodes moreli Arthur, 1957a. An Afrotropical species whose adults are usually found on Artiodactyla: Bovidae. All parasitic stages have been recovered from Bovidae; adult ticks alone have been taken from Carnivora: Felidae, Viverridae and Nandiniidae, and Rodentia: Thryonomyidae. There are no records of Ixodes moreli causing human parasitism.

Host-parasite associations in small mammal communities in semiarid savanna ecosystems of East Africa
No full textDespite the established importance of rodents as reservoirs of vector-borne zoonoses in East Africa, there is relatively limited information regarding the infestation parameters and host associations of ectoparasites that vector many such pathogens among small mammals in this region. Between 2009 and 2013, small mammals were livetrapped in the semiarid savanna of Kenya. A subset of these individual hosts, including 20 distinct host taxa, was examined for ectoparasites, which were identified to species. Species of fleas, ticks, mites, and sucking lice were recorded. Based on these data, we calculated host-specific infestation parameters, documented host preferences among ectoparasites, conducted a rarefaction analysis and extrapolation to determine if ectoparasites were adequately sampled, and assessed nestedness for fleas to understand how pathogens might spread in this system. We found that the flea community structure was significantly nested. Understanding the ectoparasite network structure may have significant human relevance, as at least seven of the ectoparasite species collected are known vectors of pathogens of medical importance in the region, including Yersinia pestis, Rickettsia spp., and Theileria parva, the causative agents of plague, spotted fevers and other rickettsial illnesses in humans, and theileriosis, respectively.Ana Sofia Guerra, Ralph P.

Remote Control and Monitoring of Accelerators and Detectors in a Global Facility (GAN/GDN)
No full textFuture accelerators and experiments are operated by large international collaborations and typically by dispersed teams of experts. The facilities will be operated over many years and even decades. It will be prohibitive to maintain a complete staff of experts at the site. The load of regular visits of the site is tremendously eased when experts can take action remotely. The demand for reliable remote monitoring and control is thus paramount. This paper describes a comprehensive solution which is being provided by the GANMVL-collaboration within EuroTeV. An important feature of the toll is that the implementation details are well hidden from the user to increase the public acceptance. The tools employed are based on web-browsers granting access to VNC, to VRVS and in the future EVO, to facility internal web-pages, to cameras and allow to control instruments. They include Single Sign On authentication so that security requirements can be met. Using standard interfaces the user need not be concerned with the technology of the instruments. The paper will include a demonstration of the current status of development
Standard Model Tests at very high
No full text. With the e-p collider HERA at DESY tests of the Standard Model at highest available Q 2 have been performed. Recent results on the cross section for deep inelastic e-p scattering up to Q 2 = 40000GeV 2 are presented. An analysis of events with high missing transverse momentum p t and an isolated lepton is discussed. Limits on the production of leptoquarks, excited fermions and on Contact Interactions are given. INTRODUCTION With the e-p collider HERA at DESY electron proton scattering processes 1 at a maximum center of mass energy p s = 300GeV offer the possibility to study deep inelastic scattering (DIS) in charged and neutral current processes up to a momentum transfer of Q 2 = 90000GeV 2 . With the large data sample from 1997 both collaborations H1 and ZEUS have refined their analyses and measured cross sections up to Q 2 = 40000GeV 2 . This extends previous measurements of fixed target experiments by 2 orders of magnitude in Q 2 . A new domain in DIS has been..
Measurement of Deeply Virtual Compton Scattering at HERA
No full textA measurement is presented of elastic Deeply Virtual Compton Scattering e + p ! + + p at HERA using data taken with the H1 detector. The cross section is measured as a function of the photon virtuality, Q , and the invariant mass, W , of the p system, in the kinematic range 2 , where t is the squared momentum transfer to the proton. The measurement is compared to QCD based calculations. To be submitted to Physics Letters B C. Adloff , V. Andreev , B. Andrieu , T. Anthonis , V. Arkadov , A. Astvatsatourov A. Babaev , J. Bahr , P.

Trigger/Data Acquisition Issues and Challenges for the Next Generation of Experiments at the Future International Linear Collider
No full textEvidence for a Narrow Anti-Charmed Baryon State H1 Collaboration
No full textA narrow resonance in D # - p and D # p invariant mass combinations is observed in inelastic electron-proton collisions at centre-of-mass energies of 300 GeV and 320 GeV at HERA. The resonance has a mass of 3099 5 (syst.) MeV and a measured Gaussian width of 12 3 (stat.) MeV, compatible with the experimental resolution. The resonance is interpreted as an anti-charmed baryon with a minimal constituent quark composition of uuddc, together with the charge conjugate. To be submitted to Phys. Lett. B A. Aktas , V.
