Physical and Social Factors of Shoreline Change in Gebang, Cirebon Regency 1915 – 2019
Shoreline changes are the main concern for coastal management. In Indonesia coastal zone is the populated region for marine and fishery economic sectors. Dynamic of the region shown by shoreline change.

Formation of planetary systems by pebble accretion and migration [PDF]
At least 30% of main sequence stars host planets with sizes of between 1 and 4 Earth radii and orbital periods of less than 100 days. We use N-body simulations including a model for gas-assisted pebble accretion and disk–planet tidal interaction to study

Formation of an Accretion Flow [PDF]
After a star has been tidally disrupted by a black hole, the debris forms an elongated stream. We start by studying the evolution of this gas before its bound part returns to the original stellar pericenter. While the axial motion is entirely ballistic, the transverse directions of the stream are usually thinner due to the confining effects of self ...

Stochastic accretion of the Earth
The Earth is depleted in volatile elements relative to chondritic meteorites, its possible building blocks. Abundances of volatile elements descend roughly log-linearly with their calculated volatilities during solar nebula condensation [1, 2]. This depletion, however, is not accompanied by any stable isotope fractionation, which would otherwise be ...

Lakes and their shorelines are important ecosystem areas with the diversity of living species they host. In addition, lakes are an almost indispensable resource for humans as a source of fresh water.

Reference Array and Design Consideration for the Next-Generation Event Horizon Telescope
We describe the process to design, architect, and implement a transformative enhancement of the Event Horizon Telescope (EHT). This program—the next-generation Event Horizon Telescope (ngEHT)—will form a networked global array of radio dishes capable of ...

Accretion Dynamics on Wet Granular Materials. [PDF]
Wet granular aggregates are common precursors of construction materials, food, and health care products. The physical mechanisms involved in the mixing of dry grains with a wet substrate are not well understood and difficult to control.

Persistence of tidal wetlands under conditions of sea level rise depends on vertical accretion of organic and inorganic matter, which vary in their relative abundance across estuarine gradients.

The Radiative Transfer in Accretion Discs with Linear Plank Function: Role of Scattering Effect [PDF]
Radiative transfer in a geometrically thin accretion disc with fnite optical depth is considered under the plane-parallel approximation. The Eddington factor that is defned as the ratio of the mean intensity to radiation stress tensor, is assumed be ...

In this paper, we formulate a geometric nonlinear theory of the mechanics of accreting–ablating bodies. This is a generalization of the theory of accretion mechanics of Sozio & Yavari (Sozio & Yavari 2019 J. Nonlinear Sci. 29 , 1813–1863 (doi:10.1007/s00332-019-09531-w)).
