Correct operation of real-time systems (RTS) is defined as producing correct results within given time constraints (deadlines). As RTS are becoming more susceptible to soft errors, employing fault-tolerant techniques is crucial. Rollback Recovery with Checkpointing (RRC) is an efficient fault-tolerant technique. However, RRC introduces a time overhead which depends on the number of checkpoints. Th
(equation presented) The synthesis of α-substituted α,β-enones by a new metal iodide-promoted one-pot three-component reaction involving commercially available cyclopropyl ketones, aldehydes, and secondary amines followed by base treatment is described.
Communication interventions are commonly proposed as a way to address people's fear and negative attitudes to build tolerance in shared landscapes between humans and large carnivores. Therefore, managing authorities sometimes respond to people's fear of brown bears (Ursus arctos) by organizing an information meeting. This study increases the understanding of the information meeting to address fear
Starting from next year the technical feasibility of a direct seeding scheme at 30 and 13 nm will be studied at the Free-electron LASer in Hamburg (FLASH). During a major shutdown the SASE-FEL facility will be upgraded and it is planned to install in addition a high-harmonic generation (HHG) seed laser, a new chain of 10 m variable gap un-dulators and a dedicated commissioning beamline for photon
Retinal implant devices are becoming an increasingly realizable way to improve the vision of patients blinded by photoreceptor degeneration. As an electrode material that can improve restored visual acuity, carbon nanotubes (CNTs) excel due to their nanoscale topography, flexibility, surface chemistry, and double-layer capacitance. If vertically aligned carbon nanotubes (VACNTs) are biocompatible
The European Spallation Source Neutrino Super Beam (ESSνSB) project aims at a discovery of leptonic CP violation with a precise measurement of the CP phase angle. ESSνSB is characterized by an intense neutrino beam to be produced at ESS by a 5-MW proton beam, and the placement of the far detector at the second oscillation maximum. The aims of the near detector for ESSνSB are neutrino flux and inte
Thefirst reported applications of laser sheet imaging for the study of atomizing sprays date from the mid 1980th.Since those early tries, blurring effects from the light being scattered multiple times by the surrounding dropletswere already observed and reported. While s trategies in suppressing part of this multiple light scatteringcontribution, were known for transmission imaging (e. spatial Fou
Pythia8 is the only general purpose event generator able to produce complete fully exclusive hadronic final states in collisions involving heavy ions. The model that allows this is called Angantyr and will be discussed in this contribution. The contribution also discusses models based on interactions between strings in an extention of the Lund model that are able to describe some collective effect
We investigate stability issues for steady states of the spherically symmetric Einstein-Vlasov system numerically in Schwarzschild, maximal areal, and Eddington-Finkelstein coordinates. Across all coordinate systems we confirm the conjecture that the first binding energy maximum along a one-parameter family of steady states signals the onset of instability. Beyond this maximum perturbed solutions
Entropy production is a key concept of thermodynamics and allows one to analyze the operation of engines. For the Scovil-Schulz-DuBois heat engine, the archetypal three-level thermal maser coupled to thermal baths, it was argued that the common definition of heat flow may provide negative entropy production for certain parameters [Boukobza and Tannor, Phys. Rev. Lett. 98, 240601 (2007)PRLTAO0031-9
Cancer results from a sequence of genetic and epigenetic changes that lead to a variety of abnormal phenotypes including increased proliferation and survival of somatic cells and thus to a selective advantage of precancerous cells. The notion of cancer progression as an evolutionary process has been attracting increasing interest in recent years. A great deal of effort has been made to better unde
Mesenteric duct chylomicrons labelled with [3H]arachidonic (20:4) and [14C]linoleic (18:2) acid were injected intravenously into essential fatty acid-deficient (EFAD) and control rats. The rats were killed after 5, 10, 20 and 240 min, and serum and different organs were analysed for radioactivity of different lipid classes. 3H and 14C in the triacylglycerol (TG) and phosphatidylethanolamine (PE) f
Charge balance functions reflect the evolution of charged pair correlations throughout the stagesof pair production, dynamical diffusion, and hadronization in heavy-ion collisions. Microscopic mod-eling of these correlations in the full collision volume shows that the balance functions are sensitiveto the diffusivity of light quarks when studied as functions of relative azimuthal angle.
