DIAMONDS: a new Bayesian Nested Sampling tool. Application to Peak Bagging of solar-like oscillations [PDF]

open access: yes, 2014
To exploit the full potential of Kepler light curves, sophisticated and robust analysis tools are now required more than ever. Characterizing single stars with an unprecedented level of accuracy and subsequently analyzing stellar populations in detail ...

On Sub-Propositional Fragments of Modal Logic [PDF]

open access: yes, 2018
In this paper, we consider the well-known modal logics $\mathbf{K}$, $\mathbf{T}$, $\mathbf{K4}$, and $\mathbf{S4}$, and we study some of their sub-propositional fragments, namely the classical Horn fragment, the Krom fragment, the so-called core ...

Diamond fingerprinting for source discrimination using laser ablation inductively coupled plasma mass spectrometry (LA-ICP-MS) and Fourier transform infrared spectrometry (FTIR)

open access: yesHeliyon, 2020
The Kimberley Process Certification Scheme (KPCS) was established in 2000 as a means of controlling the flow of conflict diamonds, mostly, from the African continent. In 2013, the KPCS imposed an embargo on diamonds from the Central African Republic (CAR)

Deforming diamond

open access: yesIMA Journal of Applied Mathematics, 2016
For materials science, diamond crystals are almost unrivaled for hardness and a range of other properties. Yet, when simply abstracting the carbon bonding structure as a geometric bar-and-joint periodic framework, it is far from rigid. We study the geometric deformations of this type of framework in arbitrary dimension d, with particular regard to the ...

Application of introduced nano-diamonds for the study of carbon condensation during detonation of high explosives

open access: yes, 2008
This paper describes the experimental studies of the formation of nano-diamonds during detonation of TNT/RDX 50/50 mixture with small-angle x-ray scattering (SAXS) method at a synchrotron radiation beam on VEPP-3 accelerator.

Black Diamonds at Brane Junctions [PDF]

open access: yes, 2000
We discuss the properties of black holes in brane-world scenarios where our universe is viewed as a four-dimensional sub-manifold of some higher-dimensional spacetime.

Pursuing colloidal diamonds

open access: yesNanoscale, 2023
The endeavor to selectively fabricate a cubic diamond is challenging due to the formation of competing phases such as its hexagonal polymorph or others possessing similar free energy. Here, we demonstrate how one can attain such selectivity.

Policy Impacts on Africa’s Extractive Sector: Botswana, Diamond Dependence, and Diversification in the Post-Diamond Period

open access: yesRevue Gouvernance, 2018
This paper investigates the topic of sustainable natural resource governance, and policy and politics thereof, in the context of Botswana. The authors endeavour to provide a preliminary justification for why Botswana, as a country of investigation, is a ...
