Ultrafast imaging of granular impacts, dynamics and wave propagation phenomena

Johan SCHAAP · Stephen HALL · Bratislav LUKIC · Jonas ENGQVIST

The ultrafast imaging with fields-of-view (FoVs) up to 12 x 8 mm2 now possible at ID19 enables study of phenomena propagating at up to a few 100’s-1000’s m/s. This opens exciting possibilities to study the mechanisms of impacts, wave propagation and dissipation mechanisms in (saturated) granular media and how these are...

Charge density distribution in La3Ni2O7 at high pressures

Huć, Agnieszka · Sundaramurthy, Vignesh · Wehinger, Bjorn

The recent discovery of pressure-induced superconductivity in La3Ni2O7 with a Tc close to 80K at pressures above 14GPa has generated considerable attention and calls for further investigation of the underlying mechanism. While the structure of the high-pressure phase that accommodates superconductivity could only be gu...

Apatite crystal deformation around the tooth cemento-dentine junction in roots: nanoXRD mapping and annealing of residual strains in a bioge

Janina ZOGLAUER · Ahmed KAMAL MAHGOUB ALI · Paul ZASLANSKY · Julie VILLANOVA · y 1 más

The cemento-dentine junction (CDJ) is an astoundingly fatigue-resistant interface between two tissues: tooth root dentine and cementum. It sustains millions of chewing cycles without failure, yet the role of residual strain between collagen protein and nanocrystals is not known. We propose to correlate nanostructure an...

Recurrent hybridization shapes the diversification of Western Palearctic common toads (Bufo bufo complex)

Christophe, Dufresnes · Sven, Gippner · Sylvia, Hofmann · Ilias, Strachinis · y 6 más

Glacial cycles repeatedly fragmented temperate species into refugial populations, fostering divergence as a first stage towards speciation. Yet, interglacial expansions often reconnected these lineages, allowing gene flow to erode differentiation and reshape phylogeographic trajectories. We investigate these dynamics i...

Parallel spawning strategies for dynamic-aware MPI applications

Iker Martín-Álvarez · José Ignacio Aliaga · Maribel Castillo · Sergio Iserte

Dynamic resource management is an increasingly important capability of High Performance Computing systems, as it enables jobs to adjust their resource allocation at runtime. This capability can reduce workload makespan, substantially decreasing job waiting times and optimizing resource allocation. In this context, mall...

Acyclic list colouring locally planar graphs

Postle, Luke · Smith-Roberge, Evelyne · Vicenzo, Massimo

A (vertex) colouring of graph is \emph{acyclic} if it contains no bicoloured cycle. In 1979, Borodin proved that planar graphs are acyclically 5-colourable. In 2010, Kawarabayashi and Mohar proved that locally planar graphs are acyclically 7-colourable. In 2002, Borodin, Fon-Der-Flaass, Kostochka, Raspaud, and Sopena p...

Unveiling the reaction dynamics of Li3BO3 high-capacity CO2 sorbent

María Laura GRASSO · Maria Valeria BLANCO · Maria Jose OROZCO · Chloe FULLER · y 2 más

Solid sorbets for CO2 capture applications are a technological pathway to prevent CO2 emissions from being released to the atmosphere and are therefore a key strategy to mitigate global warming. In this work, we aim to explore the reaction dynamics of high-temperature CO2 capture of the recently proposed high-capacity...

Exponential dichotomies for elliptic equations on multidimensional domains

Beck, Margaret · Goh, Ryan · Haslam-Hyde, Alanna

The existence of exponential dichotomies has been well-established as a powerful tool to study existence, stability, and bifurcations of coherent structures. Currently, the application of exponential dichotomies to elliptic problems posed on multi-dimensional domains is predominately limited to the context of cylindric...
