Jan 18, 2022 by Enrico de Lazaro

A team of scientists from the University of Salzburg and the University of Basel has presented sleeping volunteers with their own names and unfamiliar names spoken by either a familiar or an unfamiliar voice. While we snooze, our brain continues to monitor the environment, balancing the need to protect sleep with the need to wake up; one example of how the brain accomplishes this is by selectively responding to unfamiliar voices over familiar ones....

Scanning electron microscopy image of a nanopatterned YBa2Cu3O7−δ (YBCO) thin film. The 12-nm-thick nanopatterned YBCO thin film was fabricated by reactive ion etching through an anodic aluminium oxide (AAO) membrane directly placed atop the YBCO. By RIE, the anodized aluminium oxide pattern of a triangular array of holes with ~70-nm diameter and ~103-nm period was duplicated onto the YBCO film.

Study area and hybrid-frequency waveform earthquakes (EHWs): (a) hydraulic fracturing activity and seismicity in northeast British Columbia, Canada; the top-right inset shows the geographic location of the study area (red rectangle); blue diamonds: hydraulic fracturing injection wells between January 1, 2014 and December 31, 2016, reported by the British Columbia Oil and Gas Commission; yellow dots: earthquakes during the same period; stars: 10 M 4-5 earthquakes since 2008; black rectangle: study area in which EHWs occurred; (b, c) comparison between representative examples of a typical induced event (black trace) and an EHW (purple trace); both waveforms are from the vertical component of station MG03 with comparable source-station distance (1.32 km vs. 1.65 km) and magnitudes (MW1.5); manually picked P/S-arrivals are marked; the comparison of P/S-pulse shape demonstrates the relatively wider pulses for EHWs; (d, e) the same as (b) and (c) but for waveforms recorded at station MG02; both events show longer coda durations with slightly larger epicentral distances; note that although both types of events have extended coda durations, the EHW contains a relatively larger proportion of lower-frequency energy in the coda.
