S-Net for multi-memory multicores
(ACM Press, 2010)S-Net is a declarative coordination language and component technology aimed at modern multi-core/many-core architectures and systems-on-chip. It builds on the concept of stream processing to structure dynamically evolving ... -
The s-process branching at W-185
(2003-01-20)The neutron capture cross section of the unstable nucleus W-185 has been derived from experimental photoactivation data of the inverse reaction W-186(gamma, n) W-185. The new result of sigma = 687 +/- 110 mbarn confirms ... -
s-process branchings at Sm-151, Eu-154, and Dy-163
(2001-07)The (n, gamma) cross sections of the stable europium isotopes Eu-151 and Eu-153 have been measured by irradiating oxide samples in a quasistellar neutron spectrum. From the induced activities, the stellar cross sections ... -
The s-process nucleosynthesis : Impact of the uncertainties in the nuclear physics determined by monte carlo variations
(2017-10-01)We investigated the impact of uncertainties in neutron-capture and weak reactions (on heavy elements) on the s-process nucleosynthesis in low-mass stars and massive stars using a Monte-Carlo based approach. We performed ... -
The s-Process Nucleosynthesis in Low Mass Stars : Impact of the Uncertainties in the Nuclear Physics Determined by Monte Carlo Variations
(Springer Nature, 2019-08-20)We investigated the impact of uncertainties in neutron-capture and weak reactions (on heavy elements) on the s-process nucleosynthesis in low-mass stars using a Monte-Carlo based approach. We performed extensive nuclear ... -
S-process production in rotating massive stars at solar and low metallicities
(2015-12-28)Rotation was shown to have a strong impact on the structure and light element nucleosynthesis in massive stars. In particular, models including rotation can reproduce the primary nitrogen observed in halo extremely metal ... -
The /s/ morpheme and the compounding phenomenon in English.
(2002)Compound words with irregular plural nouns in first position (e.g. mice-eater) are produced far more frequently than compound words with regular plural nouns in first position (e.g. *rats-eater), (Gordon, 1985). ... -
S1-sensitive sites in the supercoiled double-stranded form of tomato golden mosaic virus DNA component B : Identification of regions of potential alternative secondary structure and regulatory function
(1985-07-11)The sensitivity of the supercoiled double-stranded form of the DNA of tanato golden mosaic virus (TGMV), a geminivirus, to the single-strand specific enzyme S1 nuclease has been demonstrated. Specific S1 cleavage sites ... -
SAC - A functional array language for efficient multi-threaded execution
(2006-08-01)We give an in-depth introduction to the design of our functional array programming language SaC, the main aspects of its compilation into host machine code, and its parallelisation based on multi-threading. The language ... -
SaC -- from high-level programming with arrays to efficient parallel execution
(2003)SAC is a purely functional array processing language designed with numerical applications in mind. It supports generic, high-level program specifications in the style of APL. However, rather than providing a fixed set of ... -
Safety education of pedestrians for injury prevention
(2002)Background: Each year about one million people die and about 10 million are seriously injured on the world's roads. Educational measures to teach pedestrians how to cope with the traffic environment are considered to be ... -
Safety First? : A map of public sector research into GM food and food crops in the UK

Safety Measures to Reduce Medication Administration Errors in Paediatric Intensive Care Unit
(2015-08-25)Objective: Medicine administration is the last process of the medication cycle. However, errors can happen during this process. Children are at an increased risk from these errors. This has been extensively investigated ... -
Safety of medication use in primary care
(2015-02)BACKGROUND: Medication errors are one of the leading causes of harmin health care. Review and analysis of errors have often emphasized their preventable nature and potential for reoccurrence. Of the few error studies ... -
Safety, risk, and danger : A new dynamic perspective

A Safety-Case Approach to the Ethics of Autonomous Vehicles
(2019-12-13)Autonomous Vehicles (AVs) have significant ethical and safety implications. Questions of informed consent and risk acceptance are of primary importance, as is an explicit identification of the ethical principles underlying ... -
Saharan dust and heterogeneous ice formation : Eleven years of cloud observations at a central European EARLINET site
(2010-10-19)More than 2300 observed cloud layers were analyzed to investigate the impact of aged Saharan dust on heterogeneous ice formation. The observations were performed with a polarization/Raman lidar at the European Aerosol ...
