Last Abundant Appearance Datum of Hemidiscus karstenii driven by climate change

open access: yes, 2020
The Last Abundant Appearance Datum of the endemic Southern Ocean diatom Hemisdiscus karstenii Jouse is dated at around 190,000 years Before Present, which provides a robust and convenient biostratigraphic marker to Late Pleistocene paleoceanographic ...

Cauchy Problem for the Spatially Homogeneous Landau Equation with Shubin Class Initial Datum and Gelfand-Shilov Smoothing Effect [PDF]

open access: yesSIAM Journal on Mathematical Analysis, 2017
In this work, we study the nonlinear spatially homogeneous Lan-dau equation with Maxwellian molecules, by using the spectral analysis, we show that the non linear Landau operators is almost linear, and we prove the existence of weak solution for the ...

3D Reconstruction via Depth and Normal Priors Guided 3D Gaussian Splatting [PDF]

open access: yesThe International Archives of the Photogrammetry, Remote Sensing and Spatial Information Sciences
This paper introduces a novel 3D reconstruction method that leverages depth and normal priors within a 3D Gaussian splatting framework. The approach aims to address the limitations of traditional 3D reconstruction methods, which often involve complex ...

Non-orthogonal geometric realizations of Coxeter groups [PDF]

open access: yes, 2012
We define in an axiomatic fashion a \emph{Coxeter datum} for an arbitrary Coxeter group $W$. This Coxeter datum will specify a pair of reflection representations of $W$ in two vector spaces linked only by a bilinear paring without any integrality and non-

Corruption: The hidden perpetrator of under-development and vulnerability to natural hazards and disasters

open access: yesJàmbá, 2011
My lecture is based upon a fully referenced paper but it is not an academic paper that contains evidence from which it draws conclusions. It’s in the nature of corruption that there is little evidence and there are no text-books, no journals devoted to ...

THE IMPLEMENTATION OF MODERN GEOCENTRIC DATUM: A REVIEW [PDF]

open access: yesThe International Archives of the Photogrammetry, Remote Sensing and Spatial Information Sciences, 2019
A dynamic datum denotes a coordinate datum in real-time linked with the International Terrestrial Reference Frame (ITRF) in order to provide a dynamic ITRF-like datum to the users.

The Equus Datum and the Early Radiation of Equus in China

open access: yesFrontiers in Ecology and Evolution, 2019
For comprehensive recognition on Equus Datum, we review all the stenonid species in China and discuss the phylogenetic relationship of early Equus. The conclusion indicates at least two dispersal waves of Equus into the Old World from North America, and ...

Abstract Hodge decomposition and minimal models for cyclic algebras [PDF]

open access: yes, 2008
We show that an algebra over a cyclic operad supplied with an additional linear algebra datum called Hodge decomposition admits a minimal model whose structure maps are given in terms of summation over trees.

A Method to Construct Depth Datum Geodesic Height Model for GNSS Bathymetric Survey

open access: yesJournal of Marine Science and Engineering, 2022
Water depth measurement requires the establishment of one or more tidal stations in the survey area for synchronous water level observation, and finally the water depth is estimated to the depth datum.

Fr\'echet differentiability of mild solutions to SPDEs with respect to the initial datum [PDF]

open access: yes, 2019
We establish n-th order Fr\'echet differentiability with respect to the initial datum of mild solutions to a class of jump-diffusions in Hilbert spaces. In particular, the coefficients are Lipschitz continuous, but their derivatives of order higher than ...
