Expected and observed 95% lower limits on the vector-like bottom quark mass as a function of the branching ratio, asumming that the vector-like quarks exclusively decay to SM particles (and third generation quarks).
Elektroutlenianie przepracowanego oleju 15W-40
2017
W pracy przedstawiono badania nad możliwością wykorzystania odpadowego oleju silnikowego 15W-40 do bezpośredniego pozyskiwania energii elektrycznej. Pomiary obejmowały elektroutlenianie emulsji odpadowego (zużytego) oleju silnikowego 15W-40 na gładkiej elektrodzie platynowej w kwasowym elektrolicie (H2SO4). Do wytworzenia emulsji wykorzystano detergent Syntanol DS-10. Pomiary przeprowadzono w temperaturze 293-333K. Maksymalna uzyskana gęstość prądu wyniosła 19 mA/cm2 (dla temp. 333K). Badania wykazały możliwość bezpośredniego wytwarzania prądu elektrycznego z odpadowego oleju silnikowego 15W40, a więc możliwość zasilania nim ogniw paliwowych.
Open-source QCD analysis of nuclear parton distribution functions at NLO and NNLO
2019
We present new sets of nuclear parton distribution functions (nPDFs) at next-to-leading order (NLO) and next-to-next-to-leading order (NNLO). Our analyses are based on deeply inelastic scattering data with charged-lepton and neutrino beams on nuclear targets. In addition, a set of proton baseline PDFs is fitted within the same framework with the same theoretical assumptions. The results of this global QCD analysis are compared to existing nPDF sets and to the fitted cross sections. Also, the uncertainties resulting from the limited constraining power of the included experimental data are presented. The published work is based on an open-source tool, xFitter, which has been modified to be ap…
The Advent of Open Source Democracy and Wikipolitics: Challenges, Threats and Opportunities for Democratic Discourse
2011
It has been claimed that the Web 2.0, the open source movement, and the emerging mode of peer production have inaugurated a new era of debate about openness, participation, and cooperation as bedrocks for rebuilding the civilizations of the modern world. By way of introducing the concept of wikipolitics, this paper examines whether, and if so how, politics and democracies can benefit from this emerging participatory spirit and modern ICTs, and to document possible dangers of such a shift in the democratic process. peerReviewed
Du « socialisme de cœur » zolien, ou comment être considéré en même temps comme « socialiste » et « ennemi du peuple »
2020
When Germinal was published in 1885, the critic classified Zola as a “socialist” writer. The author himself used this adjective many times referring to his work. At the same time, he didn’t know Marxism and was a resolute opponent to revolution, equality and the government by the people. The paper aims to explain some aspects of Zola’s “socialism” taking into account his origins, his youth experiences and the evolution of his works. This might help to understand the particular meaning done to the term by the writer. Suite à la publication de Germinal en 1885, la critique a classé Zola comme un écrivain « socialiste ». Le romancier lui-même a utilisé ce qualificatif plusieurs fois en parlant…
Induction of body weight loss through RNAi-knockdown of APOBEC1 gene expression in transgenic rabbits
2014
In the search of new strategies to fight against obesity, we targeted a gene pathway involved in energy uptake. We have thus investigated the APOB mRNA editing protein (APOBEC1) gene pathway that is involved in fat absorption in the intestine. The APOB gene encodes two proteins, APOB100 and APOB48, via the editing of a single nucleotide in the APOB mRNA by the APOBEC1 enzyme. The APOB48 protein is mandatory for the synthesis of chylomicrons by intestinal cells to transport dietary lipids and cholesterol. We produced transgenic rabbits expressing permanently and ubiquitously a small hairpin RNA targeting the rabbit APOBEC1 mRNA. These rabbits exhibited a moderately but significantly reduced …
Exposition continue à des mélanges de perturbateurs endocriniens
2012
Dans ce projet, il est question d’explorer les effets de mélanges de perturbateurs endocriniens sur plusieurs générations, en considérant des cibles différentes (appareil reproducteur, glande mammaire, os, dent, tissu adipeux, glandes salivaires, cerveau...) et adaptées à chaque âge pour essayer de mieux comprendre comment agissent des perturbateurs endocriniens, en particulier ceux qui interfèrent avec les hormones sexuelles. Parmi les questions majeures que se pose le scientifique, figurent celles de l’effet d’une exposition prolongée à des mélanges de perturbateurs endocriniens depuis la conception jusqu’à l’âge adulte, et de la possibilité que ces expositions aient des répercussions sur…

Nucleon dissociation and incoherent J/ψ photoproduction on nuclei in ion ultraperipheral collisions at the CERN Large Hadron Collider
2019
Using the general notion of cross section fluctuations in hadron-nucleus scattering at high energies, we derive an expression for the cross section of incoherent J / ψ photoproduction on heavy nuclei d σ γ A → J / ψ Y / d t , which includes both elastic d σ γ p → J / ψ p / d t and proton-dissociation d σ γ p → J / ψ Y / d t photoproduction on target nucleons. We find that, with good accuracy, d σ γ A → J / ψ Y / d t can be expressed as a product of the sum of the d σ γ p → J / ψ p / d t and d σ γ p → J / ψ Y / d t cross sections, which have been measured at HERA, and the common nuclear shadowing factor, which is calculated using the leading twist nuclear shadowing model. Our prediction for …
Photoperiodic regulation of life-history traits before and after eclosion: egg-to-adult development time, juvenile body weight and reproductive diapa…
2012
Photoperiod is the main environmental cue used by northern insects to predict the forthcoming seasonal changes and to adjust their life-history traits to fit these changes. We studied the effects of photoperiod on egg-to-adult development time, juvenile body mass and female reproductive diapause in two northern Drosophila montana populations with different patterns of voltinism. The most interesting findings were consistent between the populations: (1) when maintained before eclosion in short day conditions, representing early autumn, the flies developed faster and were lighter than when maintained in long day conditions, representing early summer, (2) photoperiodic time measurement is appa…
