Exp-ParaDiag: Time-parallel exponential integrators for parabolic PDEs

Gobinda Garai · Nagaiah Chamakuri

This paper introduces Exp-ParaDiag, a novel time-parallel method that combines the strength of exponential integrators into the ParaDiag framework. We develop and analyze Exp-ParaDiag based on first and second order accurate exponential integrators. We establish the convergence of the proposed methods both as precondit...

Co-existence of relaxor behaviour and ferroelectric order due to interplay of lattice and dipoles in a triangular lattice antiferromagnet P

Xin FENG · ARKADEB PAL (ORCID: 0000-0003-2505-450X) · Catherine DEJOIE

Our comprehensive study on a layered triangular lattice antiferromagnet BiCrTeO6 using the magnetization (M), specific heat (Cp), dielectric (e'), synchrotron x-ray diffraction, and neutron diffraction measurements divulged two successive antiferromagnetic transitions occurring at TN1 ~16 K and TN2 ~10.5 K, where TN2 r...

Structural characterization by XAS of black phosphorus functionalized with cobalt and study of its behaviour under light

Carlo CALCATELLI · Maria CAPORALI · Francesco D ACAPITO

We aim to characterize by means of X-ray Absorption Spectroscopy solid samples of few-layer black phosphorus functionalized with cobalt. This new material was tested in our labs and resulted a very good photocatalyst for the hydrogen production from water, thus the structural study of the samples under light irradiatio...

Beyond literacy: Predicting interpretation correctness of visualizations with user traits, item difficulty, and Rasch scores

Davide Falessi · Silvia Golia · Angela Locoro · Manuel Mastrofini

Data Visualization Literacy assessments are often administered via fixed sets of Data Visualization (DV) items, despite heterogeneity in how different people interpret the same DV. In this study, we predict Human Interpretation Correctness, i.e., whether a specific person will answer a DV item correctly, prior to their...

The Israeli BAG

Sambit DAS · Petra PERNOT · Oded LIVNAH · Sofia KOLUSHEV · y 1 más

The Israeli BAG plans to increase its usage of ESRF in the coming year. We are having more projects that utilize the ESRF single crystal capabilities as well as the continuous increase in SAXS time. As mentioned last year It is not trivial to provide a summary that covers all research topics encompassed by the BAG. We...

State of the art in direct dark matter detectors: Technologies, performance, and future directions

Muad Ghaith · Khaled Obaideen

Identifying the particle nature of dark matter remains one of the most significant challenges in modern physics. Direct detection experiments aim to observe rare scattering events between dark matter particles and terrestrial targets, a task that demands extreme background suppression and sensitivity to minute energy d...

The semi-explicit nonsmooth Newmark-β time integrator for robust unilateral contact in dynamic fragmentation simulations

Thibault Ghesquière-Diérickx · Guillaume Anciaux · Vincent Acary · Jean-François Molinari

Numerical simulations of solids undergoing dynamic fragmentation, a problem characterized by dynamic fracture and dense contacts, require accurately capturing the transition from a solid continuum to interacting fragments. We use the finite-element method with the extrinsic cohesive zone model for fracture. For contact...

Surface study of the (4x1)/(1x4) structure of Anatase (001) films grown by PLD and MBE

Tchouta Duvier DZEUBOU · Hadeel HUSSAIN · Maurizio DE SANTIS · Lucio MARTINELLI · y 1 más

The objective is to determine the (4x1) surface superstructure of an anatase-TiO2(001) film grown by PLD under UHV conditions. A similar experiment was already performed on BM32 (2020013 experiment). The measured set of fractional rods, consisting of a set of seven reflections, was not sufficient to allow us to discrim...

Neoehrlichia mikurensis and Borrelia miyamotoi co-infection in an immunocompromised patient

Otto Scharff El-Nasser · Helene Mens · Nanna Andersen · Anna Grankvist · y 2 más

Neoehrlichia mikurensis and Borrelia miyamotoi are emerging tick-borne pathogens that primarily cause disease in immunocompromised individuals. Human co-infection with both pathogens has not previously been reported.A 55-year-old man receiving rituximab for primary progressive multiple sclerosis developed persistent fe...
