Abstract Probainognathia is a derived lineage of cynodonts which encompass Mammalia as their crown-group. The rich record of probainognathians from the Carnian of Argentina contrasts with their Norian representation, with only one named species. Here

The BL Lac object 3C 371 is one of the targets that are regularly monitored by the Whole Earth Blazar Telescope (WEBT) Collaboration to study blazar variability on both short and long timescales. We aim to evaluate the long-term multiwavelength (MWL)

Estimation of the Plant Controller Communication Time-Delay Considering PMSG-Based Wind Turbines

Autor: Marchi, Pablo, Estevez, Pablo Gill, Otero, Alejandro, Galarza, Cecilia

The communication control delay between the inverters and the power plant controller can be caused by several factors related to the communication link between them. Under undesirable conditions, high delay values can produce oscillations in the wind

The X-ray polarization observations made possible with the Imaging X-ray Polarimetry Explorer (IXPE) offer new ways of probing high-energy emission processes in astrophysical jets from blazars. Here we report on the first X-ray polarization observati

New methods of neutrino and anti-neutrino detection from 0.115 to 105 MeV

Autor: Solomey, Nickolas, Christl, Mark, Doty, Brian, Folkerts, Jonathan, Hartsock, Brooks, Kuznetsco, Evgen, McTaggart, Robert, Meyer, Holger, Nolan, Tyler, Pawloski, Greg, Reichart, Daniel, Rodriguez-Otero, Miguel, Smith, Dan, Solomey, Lisa

We have developed a neutrino detector with threshold energies from ~0.115 to 105 MeV in a clean detection mode almost completely void of accidental backgrounds. It was initially developed for the NASA $\nu$SOL project to put a solar neutrino detector
