Lateglacial and Holocene glacier variations in an active volcanic area, northern Jan Mayen (Nord‐Jan), Norway

open access: yesBoreas, EarlyView.
Glacier evolution and environmental changes in the northern Jan‐Mayen from the early deglaciation and well into the Holocene are discussed. Results are based on a large chronological dataset (TCN and radiocarbon dates), integrated with field data on glacial landforms and sediments, including the use of GPR.

NATO i Zapadni Balkan u uvjetima novih sigurnosnih izazova

open access: yesMeđunarodne Studije, 2014
U skladu sa zaključcima donesenim na NATO-ovom samitu u Walesu, posebno s onim kako će NATO ostati „temeljem naše kolektivne obrane“, zemlje Zapadnog Balkana svjesne su važnosti pripadanja transatlantskom sigurnosnom okruženju, vođenom od strane NATO-a ...

MARV: Multiview Augmented Reality Visualisation for Exploring Rich Material Data

open access: yesComputer Graphics Forum, EarlyView.
We propose our immersive workspace MARV, enabling material experts to analyse rich material data, that is, spatial and abstract data, seamlessly in an AR environment through 3D renderings (a), novel visualisation techniques like MDD Glyphs and Skewness Kurtosis Mapper (b), Temporal Evolution Tracker (c), and Chrono Bins (d). Abstract Rich material data

Time scales and temperatures of crystal storage in magma reservoirs: implications for magma reservoir dynamics

open access: yesPhilosophical Transactions of the Royal Society A, 2018
The thermal and therefore physical state of magma bodies within the crust controls the processes and time scales required to mobilize magmas before eruptions, which in turn are critical to hazard assessment.

Improved Precision and Reference Materials for Stable Carbon Isotope Measurement in Basaltic Glasses using Secondary Ion Mass Spectrometry

open access: yesGeostandards and Geoanalytical Research, EarlyView.
Key Points High‐precision measurement results for δ13C in basaltic glasses were achieved down to 25 μg g‐1 CO2 using a refined measurement procedure via large‐geometry SIMS. Three new hydrous basaltic glasses (ETNA24, ETNA32, ETNA36) were established as reference materials.

Finding suitable paths for the elliptic curve primality proving algorithm

open access: yesActa Universitatis Sapientiae: Informatica, 2013
An important part of the Elliptic Curve Primality Proving algorithm consists of finding a sequence of elliptic curves with appropriate properties. In this paper we consider a strategy to search for an improved sequence, as part of an implementation ...

Origin of global deep faults and their significance in Earth degasification

open access: yesМінеральні ресурси України, 2018
There are origin and formation conditions of global deep faults, their distribution patterns and also their importance in the Earth degasification from standpoint of conception of Earth Crust evolution dynamics (CECED) in article.

Lateral Magma Flow in Mafic Sill‐complexes

open access: yes, 2016
The structure of upper crustal magma plumbing systems controls the distribution of volcanism and influences tectonic processes. However, delineating the structure and volume of plumbing systems is difficult because (1) active intrusion networks cannot be

Nuclear magnetic resonance properties of silica glass under pressure up to 2 Mbar: A view from ab initio calculations

open access: yesJournal of the American Ceramic Society, Volume 108, Issue 7, July 2025.
Abstract The structures of silica (SiO2) glasses at high pressure provide insight into the thermo‐mechanical properties of chemically complex amorphous oxides upon stress, compression, and indentation. While much of our knowledge on glass structures has been garnered from high‐resolution solid‐state nuclear magnetic resonance (NMR) by probing the ...

Mestre's Finite Field Method for Searching Elliptic Curves with High Ranks

open access: yesJournal of New Theory
The theory of elliptic curves is one of the popular topics of recent times with its unsolved problems and interesting conjectures. In 1922, Mordell proved that the group of $\mathbb{Q}$-rational points on an elliptic curve is finitely generated ...
