Two types of modern sediment dispersal systems in the western Taiwan foreland basin: Sediment transfer from basin to basin

open access: yesThe Depositional Record, EarlyView.
A classical peripheral foreland basin is bounded longitudinally by a pair of marginal ocean basins (DeCelles & Giles, 1996). The WTFB sediments transfer to adjacent marginal ocean basins. The western Taiwan foreland basin (WTFB) is regarded as a classical peripheral foreland basin, longitudinally bounded by the southern Okinawa Trough (SOT) to the ...

Osteohistological characterization of notosuchian osteoderms: Evidence for an overlying thick leathery layer of skin

open access: yesJournal of Morphology, Volume 284, Issue 1, January 2023., 2023
The perpendicular insertion of Sharpey's fibers in the external cortex suggests the presence of a thick leathery skin layer overlying notosuchian osteoderms. Although intramembranous ossification is the main process involved in the development of crocodyliform osteoderms, we reported a case of metaplastic development.

The steepest watershed: from graphs to images [PDF]

open access: yesarXiv, 2012
The watershed is a powerful tool for segmenting objects whose contours appear as crest lines on a gradient image. The watershed transform associates to a topographic surface a partition into catchment basins, defined as attraction zones of a drop of water falling on the relief and following a line of steepest descent.

Lacustrine and fan‐delta sediments in syn‐rift lake basins

open access: yesThe Depositional Record, EarlyView.
A consistent model for the sequence framework and depositional pattern of asymmetric half‐grabens in syn‐rift lake basins bounded by active faults has been established, complementing existing models for marine rift successions. Syn‐rift lake basins are characterised by relatively small dimensions, steep slopes, poorly developed shoreline strata ...

The coexistence and evolution of attractors in the web map with weak dissipation [PDF]

open access: yesarXiv, 2013
The dynamics of the web map with weak linear dissipation is studied. The evolution of the coexisting attractors and the structure of their basins while changing the dissipation and nonlinearity are revealed. It is shown that the structure of the basins remains the same when the dissipation and nonlinearity changes simultaneously.

Multi‐proxy reconstruction of the Holocene vegetation and land use dynamics in the Julian Alps, north‐west Slovenia

open access: yesJournal of Quaternary Science, Volume 38, Issue 1, Page 107-122, January 2023., 2023
Abstract Small mountain lakes are natural archives for understanding long‐term natural and anthropogenic impact on the environment. This study focused on long‐term (last ca. 13 000 years) vegetation changes and sedimentary processes in the catchment area of Lake Planina pri jezeru (1430 m a.s.l.) by using mineralogical, geochemical and palynological ...
