R-matrix calculations in support of diagnostics for fusion and astrophysical plasmas
… iron (Fe II), and neutral iron (Fe I). While atomic data for the neutral stages of molybdenum and tungsten finds an important application when investigating the influx of impurities into magnetically confined fusion plasmas, atomic data for the low ion stages of iron facilitates the study of …

Dynamic Privacy Management In Services Based Interactions
… the distribution and sharing of users personal data over several data sources. Each data source is potentially managed by a different organization, which may expose its data as a Web service. Using such Web services, dynamic composition of atomic data items coupled with the context in which the …

Dirac R-matrix scattering calculations in support of plasma diagnostics
The atomic structure of singly ionised nickel (Ni II), singly ionised tungsten (W II) and doubly ionised germanium (Ge III) are thoroughly analysed and subsequently incorporated into scattering calculations. W II is needed to ensure reliable erosion diagnostics when investigating the influx of …

Reducing memory persistency overheads with transparent out-of-place updates
… applications running on NVM systems require data persistence guarantees with respect to system crashes. To address this problem, many crash-consistency techniques, including logging and shadow paging, have been proposed. However, existing solutions can suffer from significant overheads on the …

Rethinking communication libraries for asynchronous multithreaded runtimes
… features a threading-efficient runtime built on atomic data structures, fine-grained non-blocking locks, and low-level network insights. It achieves scalable multithreaded performance without sacrificing simplicity or portability. We evaluate LCI and its integrations within two major AMT …

Oscillator strength measurements in singly-ionized, doubly-ionized and neutral lanthanides and transition elements (sm, nd, pr, gd, cu, and fe) using laser-induced breakdown spectroscopy.
… determinations are dependent upon accurate atomic spectroscopic data to allow the correct interpretation of stellar absorption and emission spectra. It is well known that calculations of many astrophysically important atomic parameters are limited due to line blending, insufficient spectral …
