Parallel programming using the current state-of-the-art in software engineering techniques is hard. Expertise in parallel programming is necessary to deliver good performance in applications; however, it is very common that domain experts lack the requisite expertise in parallel programming. In order to drive the computer science research toward effectively using the available parallel hardware...

The crystallisation of laser-cooled Mg+ ion beams circulating in the table-top rf quadrupole storage ring PALLAS at a velocity of the order of 2800 m/s (beam energy 1 eV) is reviewed. Emphasis is given to the description of the experimental techniques that were required for this first realisation of crystalline beams. The equivalence of the equations of motion for rf electric and magnetic confi...

Five neonatal Pallas' cats (Otocolobus manul) at the Oklahoma City Zoo died from toxoplasmosis with concurrent herpesvirus infection. These multiple infections suggested underlying immunodeficiency, perhaps caused by concurrent infection with feline immunodeficiency virus (FIV); so blood samples were collected for serology, serum protein electrophoresis, lymphocyte proliferation assays, and cyt...

In May 1996 the Denver Zoological Gardens obtained two male and two female Pallas' cats (Otocolobus felis manul) that were wild-caught in the Ukraine. These animals were part of a group of 16 wild-caught adults (eight male and eight female) imported to the United States and Canada between 1995 and 1996. The Denver Zoological Gardens cats were quarantined at the zoo hospital for approximately I ...

We report on the commissioning of the table-top RF-Quadrupole storage ring PALLAS , dedicated to the experimental realization of crystalline ion beams. Images of large prolate 24Mg+-ion crystals are presented, operating PALLAS locally as a linear rf-trap and applying laser-cooling, beautifully confirming prior theoretical and experimental work. For few-ion strings, a radial oscillation of the c...

INTRODUCTION The authors present IR spectra (0.9–2.5 μm) and narrowband photometry (3.0–3.5 μm) for low-albedo asteroids Ceres, Pallas, and Bamberga. The authors compare the major mineral absorption features to those found in primary carbonaceous chondrite matrix material (CCMM) and secondary alteration products. The observed differences between spectral reflectances between the three C-type as...

Two new sulfate monoesters of hemibastadins-1 and -2 were isolated from the marine sponge Ianthella basta (Pallas) from Guam. A third new compound was tentatively assigned the structure 34-O-sulfatobastadin-9. The 1-O-sulfatohemibastadins-1 and –2 were antagonists of the RyR1-FKBP12 Ca channel under conditions where the known compound bastadin-5 exhibits potent agonism (EC50 2 μM).

Manuls or Pallas' cats (Felis manul, syn. Otocolobus manul) are endangered wild cats from Central Asia kept and bred in many zoos. Despite good breeding success young cats frequently die from acute toxoplasmosis. From 1998 to 2002, a breeding pair in the Schönbrunn Zoo in Vienna, Austria, gave birth to 24 kittens; 58 % of kittens died between the 2nd and the 14th week of life, mostly due to acu...

The phase transition of an ion beam into its crystalline state has long been expected to dramatically influence beam dynamics beyond the limitations of standard accelerator physics. Yet, although considerable improvement in beam cooling techniques has been made, strong heating mechanisms inherent to existing high-energy storage rings have prohibited the formation of the crystalline state in the...
