ARCES Observations of the TESS Circumbinary Planet TIC 172900988b
No full textAbstract: Kostov et al. (2021) report the discovery of the first transiting circumbinary planet, detected from a single sector of TESS data. ARCES observations played a role in helping to establish the parameters of the system. We briefly present an overview of this interesting planetary system and then discuss the challenges encountered in analyzing ARCES data to derive accurate radial velocities for this project
Enhanced detection and estimation of regional S-phases using the 3-component ARCES array
No full textIn September 2014, the ARCES array in Northern Norway was upgraded to consist of 3-component instruments at each of its 25 sites. It is thereby the first array station of the International Monitoring System to be fully 3-component. S-phases are of paramount importance for the detection and location of seismic events at regional distances, especially given sparse station coverage, and it is important that these phases are both detected confidently and attributed accurate slowness estimates. The slowness estimates both identify the phase and provide phase association algorithms with the information necessary to form a high-quality seismic event hypothesis. Prior to September 2014, ARCES had 3-component sensors at four sites only. While these 3-component seismometers were highly beneficial for the detection of regional S-phases, often using incoherent beams, it was often more reliable to perform f-k analysis on the 25 vertical sensors rather than the small number of available horizontal waveforms. In addition to providing an increased signal-to-noise ratio, signals on the horizontal traces are more coherent for the S-phases and display a high measure of semblance over the array. This improves the stability of f-k analysis, since the estimates are less susceptible to the effects of scattering and incoherence. The improved coherence of S-phases across the array aperture on the horizontal components provides the basis for superior secondary phase detection capability using F-detectors and other coherence-based algorithms. Analysis of regional signal coda on the 3-component array indicates different characteristics of the apparent slowness on the different components. The 27 January 2018 earthquake on Novaya Zemlya was the first seismic event close to the former Soviet nuclear test-site to be recorded using the upgraded 3-component ARCES array. We examine the evolution of the slowness pattern for on the different components of the wavetrain and speculate that a continuous f-k detector on three components may be able to detect small seismic events in the eastern Barents Sea with increased robustness and sensitivity. We review the development of the instrumentation at ARCES and explain the motivation behind the hybrid response sensors currently deployed.</p

Comparison of pedestrian behaviors between drivers and non-drivers in Chinese sample
No full textRoad safety is a serious problem worldwide. Pedestrians, as the most vulnerable road users, deserve more attention. The aims of this study were to examine the validity of the Chinese version of the pedestrian behavior scale (CPBS) in both driver and non-driver samples, and to compare pedestrian behaviors between the two samples. In addition, we assessed the association of attention with pedestrian behaviors by exploring the relationships among CPBS, Mindful Attention Awareness Scale (MAAS) and Attention-Related Cognitive Errors Scale (ARCES). Two groups were assessed, including 302 members in the population with driving experience and 307 individuals in the non-driver group without driving experience. All participants completed the CPBS, MAAS, and ARCES, and provided sociodemographic parameters. The results showed that the CPBS had acceptable internal consistency and stability structure. More importantly, pedestrian behaviors were significantly different between drivers and non-drivers. Drivers reported significantly less transgressive and aggressive behaviors compared with non-drivers. As for the relationship between attention and pedestrian behavior, the MAAS score showed a significant negative correlation with aggressive behavior in the CPBS among drivers, while the ARCES score had significant positive correlations with all three CPBS factors. In non-drivers, the MAAS score was negatively correlated with aggressive behavior and positively associated with positive behavior; the ARCES score was positively correlated with aggressive behavior.

SMART-M3 v.0.9: A semantic event processing engine supporting information level interoperability in ambient intelligence
No full textThis tutorial is addressed to all students in Electronic Engineering and Information Engineering at the Scuola di Ingegneria e Architettura of the University of Bologna attending the following courses: Laboratory of Interoperability of Embedded Systems, "Calcolatori Elettronici M" and "Attività Progettuale di Calcolatori Elettronici M".
This tutorial includes the guidelines to build distributed applications where clients may interact with physical space. Inter-client interaction occurs through a semantic event processing engine. Information interoperability is based on a shared knowledge representation model named ontology. This tutorial is focused on client design and on the SPARQL primitives that provide the means for client-event processing engine interaction
A distributed amplifier system for bilayer lipid membrane (BLM) arrays with noise and individual offset cancellation
No full textLipid bilayer membrane (BLM) arrays are required for high throughput analysis, for example drug screening or advanced DNA sequencing. Complex microfluidic devices are being developed but these are restricted in terms of array size and structure or have integrated electronic sensing with limited noise performance. We present a compact and scalable multichannel electrophysiology platform based on a hybrid approach that combines integrated state-of-the-art microelectronics with low-cost disposable fluidics providing a platform for high-quality parallel single ion channel recording. Specifically, we have developed a new integrated circuit amplifier based on a novel noise cancellation scheme that eliminates flicker noise derived from devices under test and amplifiers. The system is demonstrated through the simultaneous recording of ion channel activity from eight bilayer membranes. The platform is scalable and could be extended to much larger array sizes, limited only by electronic data decimation and communication capabilities
