Analysis of coastal management strategies in responding to shoreline changes in Karimunjawa and Kemujan Islands of Central Java, Indonesia

Journal of Degraded and Mining Lands Management
The Karimunjawa National Park area has various coastal resources and ecosystems, such as mangrove forests, seagrass, and coral reefs, which provide a habitat for several vital organisms.

How Spatially Resolved Polarimetry Informs Black Hole Accretion Flow Models

Galaxies, 2022
The Event Horizon Telescope (EHT) Collaboration has successfully produced images of two supermassive black holes, enabling novel tests of black holes and their accretion flows on horizon scales.

Contributions of organic and inorganic matter to sediment volume and accretion in tidal wetlands at steady state

Earth's Future, 2016
A mixing model derived from first principles describes the bulk density (BD) of intertidal wetland sediments as a function of loss on ignition (LOI). The model assumes that the bulk volume of sediment equates to the sum of self‐packing volumes of organic

Fires, floods and other extreme events – How watershed processes under climate change will shape our coastlines

Cambridge Prisms: Coastal Futures, 2023
Ongoing sea-level rise has brought renewed focus on terrestrial sediment supply to the coast because of its strong influence on whether and how long beaches, marshes and other coastal landforms may persist into the future.

Global Evolution of an Accretion Disk with a Net Vertical Field: Coronal Accretion, Flux Transport, and Disk Winds [PDF]

, 2017
We report results from global ideal MHD simulations that study thin accretion disks (with thermal scale height H/R = 0.1 and 0.05) threaded by net vertical magnetic fields.

Morphodynamics of wave-dominated beaches

Cambridge Prisms: Coastal Futures, 2023
Wave-dominated sandy beaches are highly valued by societies and are amongst the world’s most energetic and dynamic environments. On wave-dominated beaches with unlimited sand supply and limited influence of tide and geology, beach change has long been ...

Cold, clumpy accretion onto an active supermassive black hole [PDF]

Nature, 2016
The so-called accretion flow that powers the growth of supermassive black holes in galaxy centres is assumed to be dominated by a smooth, steady flow of very hot plasma, but now observations instead reveal a clumpy accretion of very cold molecular clouds

Multivariate analysis and modeling of shoreline changes using geospatial data

Geocarto International, 2023
Understanding of shoreline dynamics is essential to coastal management and the development of tropical archipelagic countries. Therefore, this study aims to analyze the factors affecting shoreline changes and their future predictions in Bengkayang ...

Evidence for a correlation between mass accretion rates onto young stars and the mass of their protoplanetary disks [PDF]

, 2016
A relation between the mass accretion rate onto the central young star and the mass of the surrounding protoplanetary disk has long been theoretically predicted and observationally sought.

Atmospheric signatures of giant exoplanet formation by pebble accretion [PDF]

, 2016
Atmospheric chemical abundances of giant planets lead to important constraints on planetary formation and migration. Studies have shown that giant planets that migrate through the protoplanetary disk can accrete substantial amounts of oxygen-rich ...
