Generic Riemannian Maps from Nearly Kaehler Manifolds

open access: yesComputer Sciences & Mathematics Forum, 2023
In order to generalise semi-invariant Riemannian maps, Sahin first introduced the idea of “Generic Riemannian maps”. We extend the idea of generic Riemannian maps to the case in which the total manifold is a nearly Kaehler manifold.

On the Effects of Projection on Morphology

open access: yes, 1999
We study the effects of projection of three-dimensional (3D) data onto the plane of the sky by means of numerical simulations of turbulence in the interstellar medium including the magnetic field, parameterized cooling and diffuse and stellar heating ...

Climate change‐induced distributional change of medicinal and aromatic plants in the Nepal Himalaya

open access: yesEcology and Evolution, 2022
Medicinal and aromatic plants (MAPs) contribute to human well‐being via health and economic benefits. Nepal has recorded 2331 species of MAPs, of which around 300 species are currently under trade.

On the Accuracy of Cadastral Marks: Statistical Analyses to Assess the Congruence among GNSS-Based Positioning and Official Maps

open access: yesRemote Sensing, 2022
Cadastral marks constitute a dense source of information for topographical surveys required to update cadastral maps. Historically, in Italy, cadastral marks have been the cartographic network for the implementation of mapping updates.

Distribution and diversity patterns of herpetofauna in the Pantabangan-Carranglan Watershed, Nueva Ecija, Caraballo Mountain Range, Philippines [PDF]

open access: yesBiodiversity Data Journal, 2019
The recent extensive survey conducted in the Pantabangan-Carranglan Watershed, located in the Caraballo Mountain Range during the rainy season (October to November) resulted in the recording of fifty-nine (59) species of amphibians and reptiles (17 frogs,

Density-equalizing maps for simply-connected open surfaces

open access: yes, 2017
In this paper, we are concerned with the problem of creating flattening maps of simply-connected open surfaces in $\mathbb{R}^3$. Using a natural principle of density diffusion in physics, we propose an effective algorithm for computing density ...

Determinants of the distribution of utility-scale photovoltaic power facilities across the globe

open access: yesEnvironmental Research Letters, 2022
Photovoltaic power (PV) is the fastest-growing source of renewable electricity. Making reliable scenarios of PV deployment requires information on what drives the spatial distribution of PV facilities.

Extreme Value distribution for singular measures

open access: yes, 2011
In this paper we perform an analytical and numerical study of Extreme Value distributions in discrete dynamical systems that have a singular measure. Using the block maxima approach described in Faranda et al.

Global distribution models for the major bamboo (Poaceae, Bambusoideae) clades [PDF]

open access: yesBiodiversity Data Journal
The bamboos (Poaceae, Bambusoideae) are important ecological and economic resources distributed across five continents. Maps of the distribution of the four major bamboo clades are popular in the scientific and trade literature.
