Physically driven feature engineering for deep learning applications in seismo-volcanic signal analysisNARA Subscribed
The progressive growth of seismological databases has motivated the exploration of novel methodologies for common tasks such as detection and phase-picking, with a focus on maintaining reliability comparable to human performance. This goal consistently involves leveraging deep learning techniques, which emulate sensory processing in the human brain through numerical simulations. This study introduces a physically driven featur...
Unravelling the role of oceanographic connectivity in the distribution of genetic diversity of marine forests at the global scaleNARA Subscribed
Aim Genetic diversity of marine forests results from complex interactions of eco‐evolutionary processes. Among them, oceanographic connectivity driven by dispersal through water transport is hypothesized to play a pivotal role, yet its relative contribution has not been addressed at the global scale. Here, we test how present‐day oceanographic connectivity is correlated with the distribution of genetic diversity of marine fore...
Investigating the genetic basis of vertebrate dispersal combining RNA ‐seq, RAD ‐seq and quantitative geneticsNARA Subscribed
Although animal dispersal is known to play key roles in ecological and evolutionary processes such as colonization, population extinction and local adaptation, little is known about its genetic basis, particularly in vertebrates. Untapping the genetic basis of dispersal should deepen our understanding of how dispersal behaviour evolves, the molecular mechanisms that regulate it and link it to other phenotypic aspects in order...
Dispersal is a central biological process tightly integrated into life‐histories, morphology, physiology and behaviour. Such associations, or syndromes, are anticipated to impact the eco‐evolutionary dynamics of spatially structured populations, and cascade into ecosystem processes. As for dispersal on its own, these syndromes are likely neither fixed nor random, but conditional on the experienced environment. We experimentall...
The oceans are a fundamental source for climate balance, sustainability of resources and life on Earth, therefore society has a strong and pressing interest in maintaining and, where possible, restoring the health of the marine ecosystems. Effective, integrated ocean observation is key to suggesting actions to reduce anthropogenic impact from coastal to deep-sea environments and address the main challenges of the 21st century,...
The EUREF Permanent Network Densification is a collaborative effort of 26 European GNSS analysis centers providing series of daily or weekly station position estimates of dense national and regional GNSS networks, in order to combine them into one homogenized set of station positions and velocities. During the combination, the station meta-data, including station names, DOMES numbers, and position offset definitions were caref...
Assessment of changes in atmospheric dynamics and dust activity over southwest Asia using the Caspian Sea–Hindu Kush IndexNARA Subscribed
This study examines the influence of the Caspian Sea–Hindu Kush Index ( CasHKI ) on local and synoptic meteorology as well as on dust emissions over southwest ( SW ) Asia by means of National Center for Environmental Prediction/National Center for Atmospheric Research ( NCEP‐NCAR ) re‐analysed mean sea‐level pressure ( MSLP ), geopotential height at 700 hPa and surface meridional wind, along with meteorological data at Zabol,...
