10841“…This fact has caused astronomers who seek conditions suitable for life to search for exoplanets within the “habitable zone,” the narrow band in which liquid water can exist. …”

10842por Turner, Ian L., Harley, Mitchell D., Short, Andrew D., Simmons, Joshua A., Bracs, Melissa A., Phillips, Matthew S., Splinter, Kristen D.“…The archived dataset detailed here includes the monthly subaerial profiles, available bathymetry for each survey transect extending seawards to 20 m water depth, and time-series of ocean astronomical tide and inshore wave forcing at 10 m water depths, the latter corresponding to the location of individual survey transects. …”

10843por Haigh, Ivan D., Wadey, Matthew P., Wahl, Thomas, Ozsoy, Ozgun, Nicholls, Robert J., Brown, Jennifer M., Horsburgh, Kevin, Gouldby, Ben“…The vast majority of the extreme sea level events are generated by moderate, rather than extreme skew surges, combined with spring astronomical high tides. We distinguish four broad categories of spatial footprints of events and the distinct storm tracks that generated them. …”

10844“…A subclass of extragalactic radio sources known as winged radio galaxies has puzzled astronomers for many years. The wing features are detected at radio wavelengths as low-surface-brightness radio lobes that are clearly misaligned with respect to the main lobe axis. …”

10845“…The automatic observation of the night sky through wide-angle video systems with the aim of detecting meteor and fireballs is currently among routine astronomical observations. The observation is usually done in multi-station or network mode, so it is possible to estimate the direction and the speed of the body flight. …”

10846“…Based on histological behavior, it is mainly of two types (i) Esophageal squamous cell carcinoma (ESCC), and (ii) esophageal adenocarcinoma (EAD or EAC). In astronomically immense majority of malignancies, receptor tyrosine kinases (RTKs) have been kenned to play a consequential role in cellular proliferation, migration, and metastasis of the cells. …”

10847“…Measurements by the Genesis mission have shown that solar wind oxygen is depleted in the rare isotopes, (17)O and (18)O, by approximately 80 and 100‰, respectively, relative to Earth’s oceans, with inferred photospheric values of about −60‰ for both isotopes. Direct astronomical measurements of CO absorption lines in the solar photosphere have previously yielded a wide range of O isotope ratios. …”

10849“…Imaging through opaque scattering media is critically important in applications ranging from biological and astronomical imaging to metrology and security. While the random process of scattering in turbid media produces scattered light that appears uninformative to the human eye, a wealth of information is contained in the signal and can be recovered using computational post-processing techniques. …”

From the astronomical data, we can observe that the measured values of these two indices lie on a two-dimensional surface. …”

10852Synchronizing volcanic, sedimentary, and ice core records of Earth’s last magnetic polarity reversal“…We correlate new (40)Ar/(39)Ar dates from transitionally magnetized lava flows to astronomically dated sediment and ice records to map the evolution of Earth’s last reversal. …”

10853“…Dyads of 7-year-old children with different conceptual understanding of the Earth were asked to reach a consensus about its astronomic and geometric properties. Our results show that mere minutes of deliberation can result in substantial changes in children’s conceptual representations, and moreover, that this transition was consistently in the direction of reasoned and scientific opinions. …”

The identification of various reaction products indicates that different gas-phase reaction mechanisms leading to PAH growth must occur under the same conditions to account for all observed PAH-related species, thereby revealing the complex and interconnected network of PAH formation pathways. …”

As a benchmark for computational predictions and to guide an experimental search for the ro-vibrational lines of FeH(+), we performed infrared multiple photon dissociation (IRMPD) spectroscopy of FeH(+) tagged with two argon atoms. …”
