Multivariate statistical analysis for exploring road crash-related factors in the Franche-Comté region of France
2021
Understanding and modelling road crash data is crucial in fulfilling safety goals by helping national authorities to take necessary measures to reduce crash frequency and severity. This work aims at giving a multivariate statistical analysis of road crash data from the French region of Franche-Comte with special attention to road crash gravity. The first step for this multivariate analysis was to perform Multiple Correspondence Analysis in order to assess associations between the road crash injury and several important accident-related factors and circumstances. Log-linear models are used next in order to detect associations between road crash severity and related factors such as al-cohol/d…
Bioaccumulation, Biodistribution, Toxicology and Biomonitoring of Organofluorine Compounds in Aquatic Organisms
2021
This review is a survey of recent advances in studies concerning the impact of poly- and perfluorinated organic compounds in aquatic organisms. After a brief introduction on poly- and perfluorinated compounds (PFCs) features, an overview of recent monitoring studies is reported illustrating ranges of recorded concentrations in water, sediments, and species. Besides presenting general concepts defining bioaccumulative potential and its indicators, the biodistribution of PFCs is described taking in consideration different tissues/organs of the investigated species as well as differences between studies in the wild or under controlled laboratory conditions. The potential use of species as bioi…
Monolingual and cross-lingual intent detection without training data in target languages

Acute Effects on Impact Accelerations Running with Objects in the Hand
2021
Amateur runners usually run carrying implements in their hands (keys, a mobile phone, or a bottle of water). However, there is a lack of literature about the effects of different handloads on impact accelerations. Thus, this study aimed to analyse the effects of carrying different objects in the hand on impact accelerations during running. Nineteen male recreational runners (age 24.3 ± 6.8 years, training volume of 25 ± 7.38 km/week) performed twenty minutes of running on a treadmill at 2.78 m/s with four different conditions: no extra weight, with keys, with a mobile phone, and with a bottle of water. Impact acceleration and spatio-temporal parameters were analysed through a wireless triax…
Big bounce and future time singularity resolution in Bianchi i cosmologies: The projective invariant Nieh-Yan case
2021
We extend the notion of the Nieh-Yan invariant to generic metric-affine geometries, where both torsion and nonmetricity are taken into account. Notably, we show that the properties of projective invariance and topologicity can be independently accommodated by a suitable choice of the parameters featuring this new Nieh-Yan term. We then consider a special class of modified theories of gravity able to promote the Immirzi parameter to a dynamical scalar field coupled to the Nieh-Yan form, and we discuss in more detail the dynamics of the effective scalar tensor theory stemming from such a revised theoretical framework. We focus, in particular, on cosmological Bianchi I models and we derive cla…
LeptonInjector and LeptonWeighter: A neutrino event generator and weighter for neutrino observatories
2021
We present a high-energy neutrino event generator, called LeptonInjector, alongside an event weighter, called LeptonWeighter. Both are designed for large-volume Cherenkov neutrino telescopes such as IceCube. The neutrino event generator allows for quick and flexible simulation of neutrino events within and around the detector volume, and implements the leading Standard Model neutrino interaction processes relevant for neutrino observatories: neutrino-nucleon deep-inelastic scattering and neutrino-electron annihilation. In this paper, we discuss the event generation algorithm, the weighting algorithm, and the main functions of the publicly available code, with examples.
Life Cycle Energy and Environmental Assessment of the Thermal Insulation Improvement in Residential Buildings
2021
The refurbishment of the building stock is a key strategy towards the achievement of the climate and energy goals of the European Union. This study aims at evaluating the energy and environmental impacts associated with retrofitting a residential apartment to improve its vertical envelope thermal insulation. Two insulation materials, stone wool and cellulose fibers, are compared. The life cycle assessment methodology is applied assuming 1 m2 of retrofitted vertical envelope as functional unit. Moreover, to estimate the net energy and environmental benefits achievable in the retrofitted scenario compared with the non-retrofitted one, a second analysis is performed in which the system boundar…
Kartellrechtliche Erfahrungssätze – Erfahrungssatzbasierte Anscheinsbeweise und tatsächliche Vermutungen
2021
Zusammenfassung Europäische und nationale Kartellbehörden sowie Gerichte berufen sich immer häufiger auf Erfahrungssätze oder auf sonstige erfahrungsbasierte Beweiserleichterungen. In der Rechtspraxis erfolgt die erfahrungssatzbasierte Beweisführung regelmäßig ohne ausreichende Herleitung, inhaltliche Fundierung und begriffliche Differenzierung. Dem Beitrag geht es vor dem Hintergrund und der bisher weitgehend fehlenden literarischen Aufarbeitung dieser Entwicklungen um eine Bestandsaufnahme, eine systematische Einordnung und daraus abzuleitende Folgerungen für das Kartell(verfahrens)recht.

2021
The aim of this study was to evaluate the antiproliferative activity of bioaccessible fractions (BFs) obtained by the internationally standardized INFOGEST static digestion method to Sicilian honeys of three distinct floral origins (Sulla, Thistle and Dill) and the Manuka honey (gold standard), and to compare their effects based on total polyphenol content (TPC). Differentiated CaCo-2 cells (intestinal-like) and non-differentiated CaCo-2 and HCT-116 colonic tumour-like cells were incubated for 24 h with BFs of honeys to test viability, apoptosis, mitochondrial membrane potential (MMP), ROS and cell cycle. TPC after digestion ranked in the following order: Dill > Thistle > Sulla > M…
La jurisdicción de Responsabilidades Políticas contra las mujeres, 1939-1945
2021
El objetivo del presente texto es profundizar en las especificidades de la represión franquista cuando esta se ejerció contra las mujeres. En concreto, incidir en las particularidades de una modalidad que a priori no realizaba una distinción en clave de género: la Ley de Responsabilidades Políticas, eje de la represión económica de posguerra. Por un lado, se recoge el porcentaje de encausadas en relación al impacto total en diferentes provincias, tratando de ofrecer claves explicativas. Igualmente, se plantea el problema de las cifras y la existencia de otras víctimas de la represión económica más difíciles de contabilizar. Finalmente, se reflexiona en torno a las particularidades de estos …
Systematic review and meta-analysis found that malnutrition was associated with poor cognitive development
2021
Aim: Malnutrition is a major public health issue that has been associated with high susceptibility for impaired brain development and mental functioning. However, to date studies on this topic have not been collated and appraised. This systematic review and meta-analysis investigated the association between malnutrition and cognitive development. Methods: We searched the MEDLINE, Scopus, CINAHL, Embase PsycINFO and Cochrane Library databases in English up to 8 December 2020. All studies reporting an association between nutritional status and cognitive development were included. p values of less than 0.05 were considered statistically significant and the results are reported as standardised …
Integral reduction with Kira 2.0 and finite field methods
2021
We present the new version 2.0 of the Feynman integral reduction program Kira and describe the new features. The primary new feature is the reconstruction of the final coefficients in integration-by-parts reductions by means of finite field methods with the help of FireFly. This procedure can be parallelized on computer clusters with MPI. Furthermore, the support for user-provided systems of equations has been significantly improved. This mode provides the flexibility to integrate Kira into projects that employ specialized reduction formulas, direct reduction of amplitudes, or to problems involving linear system of equations not limited to relations among standard Feynman integrals. We show…
The nexus between big data and sustainability: an analysis of current trends and developments
2021
[EN] With the development of technological innovations, Big Data is transforming the socioeconomic world, impacting almost every organization and person. The transformations associated with the development of Big Data have important consequences for the sustainability of organizations, regions, and the society as a whole, and as such, they have been specifically addressed by the academic literature focusing on sustainability. Despite its importance, and perhaps because of its rapid emergence, there is a lack of studies dealing with the analysis of this body of literature and its trends. The current research attempts to fill this gap. The study develops a bibliometric and visualization analy…

How and when do mobile media demands impact well-being? Explicating the integrative model of mobile media use and need experiences (IM3UNE)
2021
Using mobile media can be both detrimental and beneficial for well-being. Thus, explaining how and when they elicit such effects is of crucial importance. To explicate boundary conditions and processes for digital well-being, this article introduces the Integrative Model of Mobile Media Use and Need Experiences (IM³UNE). Instead of assuming mobile media to be pathogenic, the IM³UNE offers a salutogenic perspective—it focuses on how we can stay healthy when using mobile media ubiquitously in daily life. More specifically, the model assumes that both the satisfaction and the frustration of basic psychological needs are key underlying mechanisms linking demanding mobile media use to well-being…
Citizens AND HYdrology (CANDHY) : conceptualizing a transdisciplinary framework for citizen science addressing hydrological challenges
2021
Widely available digital technologies are empowering citizens who are increasingly well informed and involved in numerous water, climate, and environmental challenges. Citizen science can serve many different purposes, from the "pleasure of doing science" to complementing observations, increasing scientific literacy, and supporting collaborative behaviour to solve specific water management problems. Still, procedures on how to incorporate citizens' knowledge effectively to inform policy and decision-making are lagging behind. Moreover, general conceptual frameworks are unavailable, preventing the widespread uptake of citizen science approaches for more participatory cross-sectorial water go…
First measurement of the |t|-dependence of coherent J/ψ photonuclear production
2021
The first measurement of the cross section for coherent J/ψ photoproduction as a function of |t|, the square of the momentum transferred between the incoming and outgoing target nucleus, is presented. The data were measured with the ALICE detector in ultra-peripheral Pb–Pb collisions at a centre-of-mass energy per nucleon pair sNN=5.02TeV with the J/ψ produced in the central rapidity region |y|<0.8, which corresponds to the small Bjorken-x range (0.3−1.4)×10−3. The measured |t|-dependence is not described by computations based only on the Pb nuclear form factor, while the photonuclear cross section is better reproduced by models including shadowing according to the leading-twist approximati…

Inkonsekvent og omskiftelig?
2021
Artikkelen undersøker hvordan historikeren P.A. Munch forholdt seg til idéen om «nordisk» nasjonalitet, og hva han mente om skandinavisme-bevegelsen da den var på sitt mest populære på midten av 1800-tallet. Skandinavismen og tanken om en fellesnordisk nasjonalitet ble aktualisert i forbindelse med de to dansk-tyske krigene i 1848–51 og 1864. Samtidig tok mange aktivt avstand fra bevegelsens ambisiøse program. Ifølge den rådende historieforskningen var den norsk-nasjonale historikeren Munch en av de fremste avstandstagerne, med unntak av en kort periode etter krigsutbruddet i 1848, da han lot seg rive med av idéen og gikk inn for svensk-norsk militærhjelp til Danmark. Denne «skandinavistisk…

La construction des catastrophes météorologiques dans et par le discours spécialisé : entre dénominations et évaluations
2021
International audience; [Contexte] Si les situations de catastrophes, qu’elles soient économiques, financières ou environnementales, alimentent régulièrement les travaux en analyse du discours – tant en France que dans l’espace germanophone – c’est le plus souvent à partir des discours publics (ceux des hommes politiques, des institutions, des organisations), des discours médiatiques, en particulier la presse écrite, ou de plus en plus à partir de sources numériques natives comme les forums et les blogs ou encore les réseaux sociaux. En parallèle à cela, les travaux sur les langues dites « de spécialité » restent encore trop souvent cantonnés à des approches terminologiques qui, telles cell…
Migrants’ economic integration : problematising economic citizenship
2021
Labour market policies to include migrants in their host societies through strategic integration activities usually relate host country belonging to labour market success, commodifying citizenship. Labour market success, however, is not “belonging;” raising the question of whether “economic citizenship” is a misnomer. National citizenships embed territorial, social and ethnic hierarchies in unequal ways. Migrants at the moment of their mobility are outside these national solidarities, and thus are commodified, with their rights depending on their labour market value. Access to national citizenship rights is an important structuring element in segmenting globalizing labour markets. peerRevie…
Revisiting the patient–physician relationship under the lens of value co-creation and defensive medicine

Abstract Background Tracing the association between insect cold tolerance and latitudinally and locally varying environmental conditions, as well as key morphological traits and molecular mechanisms, is essential for understanding the processes involved in adaptation. We explored these issues in two closely-related species, Drosophila montana and Drosophila flavomontana, originating from diverse climatic locations across several latitudes on the coastal and mountainous regions of North America. We also investigated the association between sequence variation in one of the key circadian clock genes, vrille, and cold tolerance in both species. Finally, we studied the impact of vrille on fly co…

Bacteriophage Resistance Affects Flavobacterium columnare Virulence Partly via Mutations in Genes Related to Gliding Motility and the Type IX Secreti…
2021
Increasing problems with antibiotic resistance have directed interest toward phage therapy in the aquaculture industry. However, phage resistance evolving in target bacteria is considered a challenge. To investigate how phage resistance influences the fish pathogen Flavobacterium columnare, two wild-type bacterial isolates, FCO-F2 and FCO-F9, were exposed to phages (FCO-F2 to FCOV-F2, FCOV-F5, and FCOV-F25, and FCO-F9 to FCL-2, FCOV-F13, and FCOV-F45), and resulting phenotypic and genetic changes in bacteria were analyzed. Bacterial viability first decreased in the exposure cultures but started to increase after 1 to 2 days, along with a change in colony morphology from original rhizoid to …
Baryogenesis and gravity waves from a UV-completed electroweak phase transition
2021
We study gravity wave production and baryogenesis at the electroweak phase transition, in a real singlet scalar extension of the Standard Model, including vector-like top partners to generate the CP violation needed for electroweak baryogenesis (EWBG). The singlet makes the phase transition strongly first-order through its coupling to the Higgs boson, and it spontaneously breaks CP invariance through a dimension-5 contribution to the top quark mass term, generated by integrating out the heavy top quark partners. We improve on previous studies by incorporating updated transport equations, compatible with large bubble wall velocities. The wall speed and thickness are computed directly from th…
