Applying machine learning methods for the analysis of two-dimensional mass spectra.

In a measurement of isomeric yield-ratios in fission, the Phase-Imaging Ion-Cyclotron-Resonance technique, which projects the radial motions of ions in the Penning trap (JYFLTRAP) onto a position-sensitive micro-channel plate detector, has been applied. To obtain the yield ratio, that is the relative population of two states of an isomer pair, a novel analysis procedure has been developed to determine the number of detected ions in each state, as well as corrections for the detector efficiency and decay losses. In order to determine the population of the states in cases where their mass difference is too small to reach full separation, a Bayesian Gaussian Mixture model was implemented.

Rehabilitants' conscientiousness as a moderator of the intention-planning-behavior chain.

Purpose/objective: After rehabilitation, it is important to maintain adopted target behaviors such as physical activity and physical exercise. By generating detailed behavioral plans, rehabilitants may translate their intentions into actual behavior. The aim of this study was to investigate whether Conscientiousness would further facilitate this mechanism in a way that rehabilitants who are more conscientious would be more likely to act upon their plans.

The Neutrons for Science Facility at SPIRAL-2.

The neutrons for science (NFS) facility is a component of SPIRAL-2, the new superconducting linear accelerator built at GANIL in Caen (France). The proton and deuteron beams delivered by the accelerator will allow producing intense neutron fields in the 100 keV-40 MeV energy range. Continuous and quasi-mono-kinetic energy spectra, respectively, will be available at NFS, produced by the interaction of a deuteron beam on a thick Be converter and by the 7Li(p,n) reaction on thin converter.

What contributes to action plan enactment? Examining characteristics of physical activity plans.

Objectives: Individuals with chronic conditions can benefit from formulating action plans to engage in regular physical activity. However, the content and the successful translation of plans into action, so-called plan enactment, are rarely adequately evaluated. The aim of this study was to describe the content of user-specified plans and to examine whether participants were more likely to enact their plans if these plans were highly specific, viable, and instrumental.

Insights into Silica Bilayer Hydroxylation and Dissolution.

Hydroxylation and dissolution of well-structured silica bilayer films grown on a ruthenium single-crystal support (SiO/Ru(0001)) was studied by temperature programmed desorption and X-ray photoelectron spectroscopy (XPS). Water desorption signals from SiO/Ru(0001) hydroxylated by electron-bombardment of adsorbed ice at 100 K were found to be comparable to those of hydroxylated bulk silica samples and attributed to adsorbed molecular water and silanol groups (vicinal and terminal). Isotopic exchange between O-labeled SiO and O-labeled water suggests the occurrence of dynamic siloxane bond cleavage and re-formation during electron bombardment.
