Quasi-Rip: A New Type of Rip Model without Cosmic Doomsday

open access: yes, 2012
The fate of our universe is an unceasing topic of cosmology and the human being. The discovery of the current accelerated expansion of the universe significantly changed our view of the fate of the universe.

Repeat-induced point mutation in Neurospora crassa causes the highest known mutation rate and mutational burden of any cellular life

open access: yesGenome Biology, 2020
Background Repeat-induced point (RIP) mutation in Neurospora crassa degrades transposable elements by targeting repeats with C→T mutations. Whether RIP affects core genomic sequence in important ways is unknown.

A note on the term 'lithic'

open access: yesJournal of Lithic Studies, 2014
The term ‘lithic’ is derived from the ancient Greek word for ‘rock’ (lithos), used in the late fourth century BCE by the scholar Theophrastus. The term ‘lithic’ in the way we use it today, meaning small rock artifact, most often chipped or ground stone ...

Flow Characteristics of the Rip Current System near a Shore-Normal Structure with Regular Waves

open access: yesJournal of Marine Science and Engineering, 2023
Rip currents are the strong narrow seaward current produced by waves breaking on the coast. Of the many types of rip currents, the present study investigates, experimentally and numerically, the rip current system produced by the wave reflection on a ...

Quasi-Rip and Pseudo-Rip Universes Induced by the Fluid Inhomogeneous Equation of State

open access: yes, 2012
We investigate specific models for a dark energy universe leading to Quasi-Rip and Pseudo-Rip cosmologies. In the Quasi-Rip model the equation of state parameter w is less than -1 in the first stage, but becomes larger than -1 in the second stage. In the

Interpretable Deep Learning Applied to Rip Current Detection and Localization

open access: yesRemote Sensing, 2022
A rip current is a strong, localized current of water which moves along and away from the shore. Recent studies have suggested that drownings due to rip currents are still a major threat to beach safety.

Little Rip and Pseudo Rip Phenomena from Coupled Dark Energy [PDF]

open access: yes, 2013
We consider Little Rip (LR) and Pseudo Rip (PR) cosmological models with two interacting ideal fluids, corresponding to dark energy and dark matter. The interaction between the dark energy and the dark matter fluid components is described in terms of the
