Relativistic coupled cluster calculations of the electronic structure of KrH+, XeH+ and RnH+
2012
Potential energy curves of NgH+ cations (Ng = Kr, Xe, Rn) were obtained by using four-component relativistic CCSD(T) coupled cluster calculations. Dissociation energies, equilibrium bond lengths, electronic properties, such as dipole moments and electric field gradients at the nuclei, and the related spectroscopic parameters of the electronic ground state have been determined. The results obtained for KrH+ and XeH+ are in good agreement with available experimental data, while those for RnH+ have been determined for the first time at this level of theory.
Dipole reorientation and local density of optical states influence the emission of light-emittingelectrochemical cells
2020
Herein, we analyze the temporal evolution of the electroluminescence of light-emitting electrochemicalcells (LECs), a thin-film light-emitting device, in order to maximize the luminous power radiated bythese devices. A careful analysis of the spectral and angular distribution of the emission of LECsfabricated under the same experimental conditions allows describing the dynamics of the spatial regionfrom which LECs emit,i.e.the generation zone, as bias is applied. This effect is mediated by dipolereorientation within such an emissive region and its optical environment, since its spatial drift yields adifferent interplay between the intrinsic emission of the emitters and the local density of …
Cmentarz Sapieżyński w Stanisławowie
2021
This article presents the history of one of the largest Polish cemeteries in the Eastern Borderlands. Thousands of Poles, including artists, poets, writers, sculptors, prominent politicians, local government officials and soldiers fighting for Polish independence in various uprisings, were buried in the Sapieżyński Cemetery during its 200-year-long history. The necropolis was closed down by the Soviet authorities in 1980, and the entire area was bulldozed. Crushed tombstones were transported outside the city, and a theater building and a hotel were developed on the site. The paper recreates the cemetery’s history and tells the life stories of the most prominent individuals who were laid to …
Unequal rapidity correlators in the dilute limit of the JIMWLK evolution
2019
We study unequal rapidity correlators in the stochastic Langevin picture of Jalilian-Marian-Iancu-McLerran-Weigert-Leonidov-Kovner (JIMWLK) evolution in the color glass condensate effective field theory. We discuss a diagrammatic interpretation of the long-range con elators. By separately evolving the Wilson lines in the direct and complex conjugate amplitudes, we use the formalism to study two-particle production at large rapidity separations. We show that the evolution between the rapidities of the two produced particles can be expressed as a linear equation, even in the full nonlinear limit. We also show how the Langevin formalism for two-particle correlations reduces to a Balitsky-Fadin…

Simultaneous determination of eight underivatised biogenic amines in fish by solid phase extraction and liquid chromatography-tandem mass spectrometr…
2010
Biogenic amines on fish tissue are formed as a result of bacterial contamination and spoilage during storage. A new method based on liquid chromatography (LC) and tandem mass spectrometry (MS/MS) using a triple quadrupole (QqQ) analyser was developed for the analysis of eight biogenic amines (cadaverine, histamine, phenylethylamine, putrescine, spermine, spermidine, tyramine and tryptamine) in fish tissues. Sample preparation was performed by extraction with trichloroacetic acid 5% and solid phase extraction clean up with STRATA X cartridge. The MS/MS method was validated and compared with a method based on the analysis of dansyl derivatives by LC and fluorescence detector (FD). MS/MS achie…
Dipolar Rings of Microscopic Ellipsoids: Magnetic Manipulation and Cell Entrapment
2016
We study the formation and dynamics of dipolar rings composed by microscopic ferromagnetic ellipsoids, which self-assemble in water by switching the direction of the applied field. We show how to manipulate these fragile structures and control their shape via application of external static and oscillating magnetic fields. We introduce a theoretical framework which describes the ring deformation under an applied field, allowing to understand the underlying physical mechanism. Our microscopic rings are finally used to capture, entrap and later release a biological cell via magnetic command, i.e. performing a simple operation which can be implemented in other microfluidic devices which make us…

Wnt signaling recruits KIF2A to the spindle to ensure chromosome congression and alignment during mitosis
2021
Canonical Wnt signaling plays critical roles in development and tissue renewal by regulating β-catenin target genes. Recent evidence showed that β-catenin–independent Wnt signaling is also required for faithful execution of mitosis. However, the targets and specific functions of mitotic Wnt signaling still remain uncharacterized. Using phosphoproteomics, we identified that Wnt signaling regulates the microtubule depolymerase KIF2A during mitosis. We found that Dishevelled recruits KIF2A via its N-terminal and motor domains, which is further promoted upon LRP6 signalosome formation during cell division. We show that Wnt signaling modulates KIF2A interaction with PLK1, which is critical for K…
La nécropole Néolithique moyen d’Obernai ‘Neuen Brunnen’ (Bas-Rhin) : rites funéraires de la première moitié du 5e millénaire dans le sud de la plain…
2020
The Obernai ’Neuen Brunnen’ necropolis in Lower Alsace yielded 29 tombs attributed to the Middle Neolithic. It was probably founded during the Early Grossgartach, at the end of the 48th century BC, and abandoned during the Roessen, perhaps during the Early Roessen, and in any case before the middle of the 46th century BC. The most original feature of this mortuary assemblage is that most of the tombs belong to the Planig-Friedberg period (the last stylistic phase of the Grossgartach) and the Roessen. The mortuary practices of these periods are still poorly known in the region. The necropolis is composed of three spatial groups, the most ancient of which contains all the Grossgartach tombs a…
