Modelling of Systems for Real
2016
Modelling and Programming are often used together in system development. However, typically there is a large difference between the handling of modelling parts and the handling of programming parts. This leads to the fact that the transition between the two is not easy, and important information is lost as well as extra information has to be provided when combining modelling and programming. This paper shows how modelling and programming could work together in system development.
Study of J/ψ Production in Jets
2017
The production of $J/\psi$ mesons in jets is studied in the forward region of proton-proton collisions using data collected with the LHCb detector at a center-of-mass energy of 13 TeV. The fraction of the jet transverse momentum carried by the $J/\psi$ meson, $z \equiv p_{\rm T}(J/\psi)/p_{\rm T}({\rm jet})$, is measured using jets with $p_{\rm T}({\rm jet}) > 20$ GeV in the pseudorapidity range $2.5 < \eta({\rm jet}) < 4.0$. The observed $z$ distribution for $J/\psi$ mesons produced in $b$-hadron decays is consistent with expectations. However, the results for prompt $J/\psi$ production do not agree with predictions based on fixed-order non-relativistic QCD. This is the first measurement o…
The richest superclusters : I Morphology
2007
We study the morphology of the richest superclusters from the catalogues of superclusters of galaxies in the 2dF Galaxy Redshift Survey and compare the morphology of real superclusters with model superclusters in the Millennium Simulation. We use Minkowski functionals and shapefinders to quantify the morphology of superclusters: their sizes, shapes, and clumpiness. We generate empirical models of simple geometry to understand which morphologies correspond to the supercluster shapefinders. We show that rich superclusters have elongated, filamentary shapes with high-density clumps in their core regions. The clumpiness of superclusters is determined using the fourth Minkowski functional $V_3$.…
On the FON astroplate project accomplishment
2019
The plan for a photographic survey of the northern sky (FON) was proposed at the Golosiiv observatory (Main Astronomical Observatory, NAS of Ukraine, Kyiv, Ukraine) in the late 1970-ies [Pakuliak et al., 2016; Vavilova, 2016; Vavilova et al., 2017]. The last compilation of the final catalog of objects involves 5,700 digitized astroplates of four observatories: MAO NAS of Ukraine (Kyiv, Ukraine) [Andruk et al., 2016], Kitab Astronomical Observatory (Tashkent, Uzbekistan) [Yuldoshev et al., 2017], Gissar Astronomical Observatory (Dushanbe, Tajikistan) [Mullo-Abdolov et al., 2017, 2018], and the observatory in Baldone (Latvia) [Eglitis, 2017]. The consolidated catalog of positions and B-magnit…
Property and cross-border couples from the perspective of European regulation
2021
The family property regimes constitute a relevant sector of the EU regulatory framework strongly connected with fundamental rights policies. Family property offers specific issues which need to balance individual rights with general interests, especially in matter of real estate property. The fragmentation of the discipline in EU Family law, the diversity of the domestic rules regarding rights in rem requires a large use of flexibility from EU legislator and EU legal professionals. The discipline provides by EU Regulations 1103 and 1104/2016 could be an interesting example to manage cross-border couple?s interests: the principles of universality and unity have to be used appropriately and, …
Un cuento de robots : La hija cibernética de descartes
2021
French philosopher René Descartes is today valued as a forerunner of the studies of human mind, artificial intelligence and robotic systems. Throughout his work there are large references to automata and the possibility of artificial life, as well as an assessment of the differences between rational behavior of human beings and the purely mechanical of animals and automata. In addition to these references, there is a fable about the creation by the philosopher of an automaton that replicated his deceased daughter Francine, a story that is well known among the French and Anglo-Saxon specialists, but not so much in the Spanish ones, which is what settles this short work
ATLAS data quality operations and performance for 2015-2018 data-taking
2020
The ATLAS detector at the Large Hadron Collider reads out particle collision data from over 100 million electronic channels at a rate of approximately 100 kHz, with a recording rate for physics events of approximately 1 kHz. Before being certified for physics analysis at computer centres worldwide, the data must be scrutinised to ensure they are clean from any hardware or software related issues that may compromise their integrity. Prompt identification of these issues permits fast action to investigate, correct and potentially prevent future such problems that could render the data unusable. This is achieved through the monitoring of detector-level quantities and reconstructed collision ev…
Genesi geometrica delle volte centriche
1996
Un'analisi completa degli organismi voltati comporta lo studio delle molteplici componenti necessarie alla loro definizione: configurazione geometrica, sistema costruttivo, area storico-geografica di appartenenza, interpretazioni Stilistiche. L’obiettivo di questo studio è indirizzato all' analisi delle volte continue su pianta centrica definibili attraverso le leggi della geometria euclidea. L’indagine si pone all'interno dei confini relativi alla loro configurazione geometrica e il criterio adottato, svincolato da classificazioni di carattere tipologico o stilistico, propone l'identificazione di famiglie geometriche in base alla figura del poligono di base dell'impianto. Si può identifica…
Transcriptional analysis distinguishes breast implant-associated anaplastic large cell lymphoma from other peripheral T-cell lymphomas
2019
Breast implant-associated anaplastic large cell lymphoma is a new provisional entity in the revised World Health Organization classification of lymphoid malignancies, the pathogenesis and cell of origin of which are still unknown. We performed gene expression profiling of microdissected breast implant-associated anaplastic large cell lymphoma samples and compared their transcriptional profiles with those previously obtained from normal T-cells and other peripheral T-cell lymphomas and validated expression of selected markers by immunohistochemistry. Our results indicate that most breast implant-associated anaplastic large cell lymphomas exhibit an activated CD4+ memory T-cell phenotype, whi…
Effect of lactose, lactulose and bisacodyl on gastrointestinal transit studied by metal detector.
2007
SUMMARY Aim and methods: To study the effect of 45 g lactose, 30 g lactulose and 10 mg bisacodyl on gastrointestinal transit in 30 healthy volunteers by metal detector and Hinton marker method. The first set of measurements were performed under standard conditions. In a second stage, transit was slowed to twice the original value by loperamide to simulate constipation conditions. Results: Bisacodyl drastically accelerated small and large intestinal transit. Colonic transit was shortened to 23 % and to 31% of control values, without and with loperamide. Bisacodyl increased stool weight and decreased stool consistency in all persons. Lactulose marginally shortened small intestinal transit (P=…
