This paper introduces the Lang-Track-App, a smartphone application and backend system to aid second language acquisition researchers in implementing the experience sampling method (ESM). Surveying research participants with the Lang-Track-App multiple times per day can yield exceptionally rich data that can be analyzed in multiple ways. This article explains the different Lang-Track-App components
Several types of Galactic sources, like magnetars, microquasars, novae or pulsar wind nebulae flares, display transient emission in the X-ray band. Some of these sources have also shown emission at MeV-GeV energies. However, none of these Galactic transients have ever been detected in the very-high-energy (VHE; E>100 GeV) regime by any Imaging Air Cherenkov Telescope (IACT). The Galactic Transient
It is demonstrated that an accurate approximation of the screening function is crucial for a quantitative evaluation of the XPS asymmetry index α. It is also shown that the dynamical aspects of the valence electron response are important in order to get an accurate description of the XPS spectrum at finite distances from the threshold.(23 refs)
Elements of the Ordovician conodont genus Protopanderodus have been investigated in order to provide a model of reconstruction for its oral apparatus. In total, 4202 elements from the five named species representing this genus in the Swedish Middle Ordovician are included in this study; P. rectus, P. parvibasis, P. graeai, P. robustus, and P. calceatus. The well-preserved specimens were studied in
Multiple sequence alignment is the foundation of many important applications in bioinformatics that aim at detecting functionally important regions, predicting protein structures, building phylogenetic trees etc. Although the automatic construction of a multiple sequence alignment for a set of remotely related sequences cause a very challenging and error-prone task, many downstream analyses still
Using two-pulse photon echo excitation a strong resonance in the measured homogeneous dephasing time as a function of magnetic field is observed in the H-3(4)-D-1(2) transition of Pr3+:YAlO3. The resonance could only be observed at low excitation energies since it otherwise was masked by excitation intensity dependent extra dephasing processes in the crystal. Thus intensity dependent dephasing pro
The use of test-coverage measures (e.g., block-coverage to control the software test process has become an increasingly common practice. This is justified by the assumption that higher test-coverage helps achieve higher defect-coverage and therefore improves software quality. In practice, data often show that defect-coverage and test-coverage grow over time, as additional testing is performed. How
A decomposition of the field of the wave equation in three dimensions is suggested. This wave splitting decomposes the field into two components such that in free space simple propagation properties are obtained. The inhomogeneous region is assumed to have a phase velocity variation that varies only in the radial coordinate r from the origin. The suggested wave splitting is a generalization of the
We report on the preliminary results from a study of the decay of the I-pi = 8(+) T-1/2 = 2 mu s isomer in Pd-96 performed as part of the Stopped-Beam RISING campaign within the Rare Isotope Investigation at GSI (RISING). The Pd-96 ions were produced following the projectile fragmentation of a 750 MeV per nucleon Ag-107 primary beam. The reaction products were separated and identified by the in-fl
Aims: Cube copying measures visuospatial ability, which is often impaired in Alzheimer's disease (AD). Cube copying was examined as an evaluation of cholinesterase inhibitor (ChEI) treatment in AD. Methods: Eighty-five ChEI-treated AD patients were included. Cube drawings made at prebaseline, baseline, 6 months, and 12 months were assessed. Cube drawings from 56 healthy individuals were also exami
Tyr-762 is an autophosphorylation site in the human platelet-derived growth factor (PDGF) alpha-receptor. In order to investigate whether phosphorylated Tyr-762 serves as a docking site for downstream signal transduction molecules, affinity purification using an immobilized synthetic peptide containing phosphorylated Tyr-762 and its surrounding amino acid residues was performed. Proteins in HeLa c
Background. To characterize participant reasons for withdrawing from a diabetes focused longitudinal clinical observational trial (TEDDY) during the first three study years. Methods. 8677 children were recruited into the TEDDY study. At participant withdrawal staff recorded any reason parents provided for withdrawal. Reasons were categorized into (1) family characteristics and (2) protocol reasons
The Variation Ontology (VariO) is used for describing and annotating types, effects, consequences and mechanisms of variations. To facilitate easy and consistent annotations, the online application VariOtator was developed. For variation type annotations VariOtator is fully automated, accepting variant descriptions in Human Genome Variation Society (HGVS) format, and generating VariO terms, either
Although the direction of loads applied to the proximal human femur is unpredictable during sideways fall, most in vitro and numerical simulations refer to a single loading condition (15° internal rotation; 10° adduction), which has been anecdotally suggested in the 1950s. The aim of the present study was to improve in vitro simulations of sideways falls on the proximal femur. An in vitro setup w
Titanium dioxide (TiO2) has very high affinity for phosphopeptides and in recent years it has become one of the most popular methods for phosphopeptide enrichment from complex biological samples. Peptide loading onto TiO2 resin in a highly acidic environment in the presence of 2,5-dihydroxybenzoic acid (DHB), phthalic acid, lactic acid, or glycolic acid has been shown to improve selectivity signif
Colophony is not used as a fragrance ingredient. However, colophony is a well-established marker of fragrance contact allergy(2-4) . Colophony was therefore included as a fragrance allergy marker in our recent paper in BJD on contact allergy in the general population (prevalence 1.0%; 95%-CI 0.6%-1.3%)(5) . When including colophony as a fragrance marker in the article on fragrance contact allergy(
