Development of Methods for Satellite Shoreline Detection and Monitoring of Megacusp Undulations

open access: yesRemote Sensing
Coastal zones, particularly sandy beaches, are highly dynamic environments subject to a variety of natural and anthropogenic forcings. Instantaneous shoreline is a widely used indicator of beach changes in image-based applications, and it can display ...

Relative abundance of 'Bacillus' spp., surfactant-associated bacterium present in a natural sea slick observed by satellite SAR imagery over the Gulf of Mexico

open access: yesElementa: Science of the Anthropocene, 2018
The damping of short gravity-capillary waves (Bragg waves) due to surfactant accumulation under low wind speed conditions results in the formation of natural sea slicks.

Exploring the Recycling Model of Phobos Formation: Rubble-pile Satellites

open access: yesThe Astronomical Journal, 2023
Phobos is the target of the return sample mission Martian Moons eXploration by JAXA that will analyze in great detail the physical and compositional properties of the satellite from orbit, from the surface, and in terrestrial laboratories, giving clues ...

Robertsonian Fusion and Centromere Repositioning Contributed to the Formation of Satellite-free Centromeres During the Evolution of Zebras

open access: yesMolecular biology and evolution, 2022
Centromeres are epigenetically specified by the histone H3 variant CENP-A and typically associated with highly repetitive satellite DNA. We previously discovered natural satellite-free neocentromeres in Equus caballus and Equus asinus. Here, through ChIP-

Tidal Truncation of Circumplanetary Disks Fails above a Critical Disk Aspect Ratio

open access: yesThe Astrophysical Journal, 2023
We use numerical simulations of circumplanetary disks to determine the boundary between disks that are radially truncated by the tidal potential and those where gas escapes the Hill sphere. We consider a model problem, in which a coplanar circumplanetary

Nature versus nurture: what regulates star formation in satellite galaxies? [PDF]

open access: yesMonthly Notices of the Royal Astronomical Society, 2018
We use our state-of-the-art Galaxy Evolution and Assembly (GAEA) semi-analytic model to study how and on which time-scales star formation is suppressed in satellite galaxies. Our fiducial stellar feedback model, implementing strong stellar driven outflows, reproduces relatively well the variations of passive fractions as a function of galaxy stellar ...

Early Stages of Galilean Moon Formation in a Water-depleted Environment

open access: yesThe Astrophysical Journal Letters, 2023
A key feature of the Galilean satellite system is its monotonic decrease in bulk density with growing distance from Jupiter, indicating an ice mass fraction that is zero in the innermost moon Io and about half in the outer moons Ganymede and Callisto ...

Typology of forest hunting grounds [PDF]

open access: yesСибирский лесной журнал, 2023
The analysis of the developed classification schemes of forest hunting grounds is given. Previously, forest typology was taken as a basis with a 4-level division (category-class-group of types-type).
