The Impact of COVID‐19 on Open Source Development Activities: A Multi‐Method Study

open access: yesJournal of Software: Evolution and Process, Volume 38, Issue 1, January 2026.
ABSTRACT The social isolation measures resulting from the COVID‐19 outbreak changed work practices in various sectors, especially with the shift to working from home. However, the implications of the pandemic on the maintenance and evolution of open‐source software (OSS) still deserve further studies.

JMATRIX – PACKAGE FOR RELATIVISTIC J-MATRIX CALCULATIONS IN ELASTIC SCATTERING OF ELECTRONS FROM MODEL POTENTIALS

open access: yesTASK Quarterly, 2017
We present a software package JMATRIX1, consisting of two computer codes written in FORTRAN 95 and parallelized with OpenMP, implementing the so-called J-matrix method, applied to elastic scattering of electrons on the radial potential, vanishing faster

CORE-SHELL MODELLING OF AUXETIC INORGANIC MATERIALS

open access: yesTASK Quarterly, 2014
This paper investigates the suitability of the General Utility Lattice Program (GULP) for studying auxetic materials at the molecular level. GULP is a force-field based molecular modelling package which incorporates the ‘core-shell’ model for simulating

INFLUENCE OF ADDITION OF CARBON NANOTUBES ON RHEOLOGICAL PROPERTIES OF SELECTED LIQUID LUBRICANTS - A COMPUTER SIMULATION STUDY

open access: yesTASK Quarterly, 2020
This work is motivated by the improvement of anti-friction properties of lubricants by addition of CNTs proved experimentally in literature. In particular, a methodology is developed to compute the shear viscosity of liquid lubricants (Propylene Glycol)

Upscaling Models for the Large‐Scale Assessment of Soil Functions

open access: yesEuropean Journal of Soil Science, Volume 77, Issue 1, January–February 2026.
ABSTRACT The characterization and assessment of soil functions is a prerequisite for agricultural and environmental policies aimed at soil health. However, there is a lack of satisfactory models for the assessment of soil functions supply to support national and intergovernmental initiatives.

SMOOTHED PARTICLE HYDRODYNAMICS SIMULATIONS USING GRAPHICS PROCESSING UNITS

open access: yesTASK Quarterly, 2014
Smoothed Particle Hydrodynamics (SPH) is a fully Lagrangian, particle-based technique for fluid-flow modeling. As a gridless method, it appears to be a natural approach to simulate multi-phase flow with complex geometries. Since SPH involves a large set

Gamification in Stomatherapy: Virtual Game for Pressure Injury Care

open access: yesInternational Journal of Telemedicine and Applications, Volume 2026, Issue 1, 2026.
Introduction Pressure injuries are injuries caused by reduced blood circulation over regular and repetitive periods when applying pressure to a specific area of the body. This incident requires daily prevention and health promotion to prevent its occurrence.

Securing End‐To‐End Encrypted File Sharing Services With the Messaging Layer Security Protocol

open access: yesConcurrency and Computation: Practice and Experience, Volume 37, Issue 27-28, 25 December 2025.
ABSTRACT Secure file sharing is essential in today's digital environment, yet many systems remain vulnerable: if an attacker steals client keys, they can often decrypt both past and future content. To address this challenge, we propose a novel file‐sharing architecture that strengthens post‐compromise security while remaining practical.
