The CERN COMPASS experiment will investigate hadron-photon interactions, to achieve a unique Primakoff Coulomb physics program based on hadron polarizability, hybrid mesons, chiral anomaly, and meson radiative transition studies. In COMPASS, pion (kaon) polarizabilities and radiative transitions will be measured via dedicated Primakoff effect reactions such as πγ → π ′ γ and πγ → M (meson). We ...

AIMS To evaluate Compass, a new instrument for glaucoma screening and diagnosis that combines scanning ophthalmoscopy, automated perimetry, and eye tracking. MATERIALS AND METHODS A total of 320 human subjects (200 normal, 120 with glaucoma) underwent full ophthalmological evaluation and perimetric evaluation using the Humphrey SITA standard 24° test (HFA), and the Compass test that consisted...

Differentiation of multiple system atrophy with predominant parkinsonism (MSA-P) and Parkinson's disease (PD) is important, but an effective tool for differentiation has not been identified. We investigated the efficacy of the composite autonomic symptom scale 31 (COMPASS 31) questionnaire as a tool for evaluating autonomic function in parkinsonism patients. In this study, we enrolled drug-naïv...

High-throughput RNA sequencing (RNA-seq) has become an instrumental assay for the analysis of multiple aspects of an organism's transcriptome. Further, the analysis of a biological specimen's associated microbiome can also be performed using RNA-seq data and this application is gaining interest in the scientific community. There are many existing bioinformatics tools designed for analysis and v...

With the launch of the Compass-M1 satellite on 14 April 2007, China is set to become the latest entrant into global navigation satellite systems (GNSS). The satellite, sometimes referred to as Compass-2 or Beidou-2, is the first of the Compass navigation satellite system (CNSS) that will provide global satellite navigation coverage. While China has launched several other navigation satellites, ...

COMPASS is a location framework where location sources are realized as plugins that contribute probability density functions to the overall localization result. In addition, COMPASS uses a decentralized location-based service discovery based on Peer-2-Peer distributed hashtables to retrieve semantical data on the determined position. In order to demonstrate the usefulness of COMPASS as a locali...

Stereotactic body radiation therapy (SBRT) involves the delivery of substantially larger doses over fewer fractions than conventional therapy. Therefore, SBRT treatments will strongly benefit patients using vivo patient dose verification, because the impact of the fraction is large. For in vivo measurements, a commercially available quality assurance (QA) system is the COMPASS system (IBA Dosim...
