Different kinds of embodied language: A comparison between Italian and Persian languages
No full textIt is debated whether only concrete but also abstract, figurative sentences, e.g.: “She grasps the cup” vs. “She grasps the concept”, are grounded in the sensorimotor system. Importantly, studies on sentences with action verbs and motor system activation have been conducted so far only with WEIRD samples (Western cultures, in North American and European countries). The aim of our work is to investigate the relationship between language and motor responses using both concrete and abstract sentences in Italian and Persian languages. In the present study, Italian and Persian participants were asked to read the sentences on the screen. The sentences referred either literally or metaphorically to motor actions. They were accompanied by a video displaying a movement that could be congruent or incongruent with the one described in the sentence. Participants were asked to re-execute the movement observed and subsequently they had to perform the task evaluating whether the sentence made sense or not. In the Italian sample a strong effect of concreteness was present, especially in the congruent but also in the incongruent condition. In the Persian sample, instead, there was an inhibition effect of congruent trials, particularly with concrete sentences, and in the incongruent trials no difference in RTs between abstract and concrete sentences was present. Results indicate that cross-cultural differences have to be taken into account when investigating the relationship between language and action
A custodial symmetry for Zb\overline{\b}
No full textWe show that a subgroup of the custodial symmetry O(3) that protects delta rho from radiative corrections can also protect the Zbb coupling. This allows one to build models of electroweak symmetry breaking, such as Higgsless, Little Higgs or 5D composite Higgs models, that are safe from corrections to Z-> bb. We show that when this symmetry protects Zbb it cannot simultaneously protect Ztt and Wtb. Therefore one can expect to measure sizable deviations from the SM predictions of these couplings at future collider experiments. We also show under what circumstances Zb_R b_R can receive corrections in the right direction to explain the anomaly in the LEP/SLD forward-backward asymmetry A^b_{FB}
Abstract concepts in interaction: the need of others when guessing abstract concepts smooths dyadic motor interactions
No full textAbstract concepts (ACs, e.g. 'justice') are more complex compared with concrete concepts (CCs) (e.g. 'table'). Indeed, they do not possess a single object as a referent, they assemble quite heterogeneous members and they are more detached from exteroceptive and more grounded in interoceptive experience. Recent views have hypothesized that interpersonal communication is particularly crucial to acquire and use ACs. The current study investigates the reliance of ACs/CCs representation on interpersonal behaviour. We asked participants to perform a motor interaction task with two avatars who embodied two real confederates. Before and after the motor interaction task, the two confederates provided participants with hints in a concept guessing task associated with visual stimuli: one helped in guessing ACs and the other, CCs. A control study we performed both with the materials employed in the main experiment and with other materials, confirmed that associating verbal concepts with visual images was more difficult with ACs than with CCs. Consistently, the results of the main experiment showed that participants asked for more hints with ACs than CCs and were more synchronous when interacting with the avatar corresponding to the AC's confederate. The results highlight an important role of sociality in grounding ACs
Observation of B0 -> Psi(2S) K0s pi+ pi- and B0s -> Psi(2S) K0s decays
No full textUsing a data sample of root s = 13 TeV protonproton collisions collected by the CMS experiment at the LHC in 2017 and 2018 with an integrated luminosity of 103 fb(-1), the B-s(0) -> psi(2S)K-S(0) and B-0 -> psi(2S)K-S(0) pi(+) pi(-) decays are observed with significances exceeding 5 standard deviations. The resulting branching fraction ratios, measured for the first time, correspond to B(B-s(0) -> psi(2S)K-S(0))/B(B-0 Zeta -> psi(2S)K-S(0)) = (3.33 +/- 0.69(stat) +/- 0.11 (syst) +/- 0.34 (f(s)/f(d))) x 10(-2) and B(B-0 -> psi(2S)K-S(0) pi(+) pi(-))/B(B-0 -> psi(2S)K-S(0)) = 0.480 +/- 0.013 (stat) +/- 0.032 (syst), where the last uncertainty in the first ratio is related to the uncertainty in the ratio of production cross sections of B-s(0) and B-0 mesons, f(s)/f(d)

No full textWe propose a direct measurement of the Cabibbo-Kobayashi-Maskawa element Vtd at the LHC. Making use of the imbalance between d and d quark content in the proton, we show that a nonzero Vtd induces a charge asymmetry in the tW associated production. The main backgrounds to this process - tt production, and tW-associated production mediated by Vtb - give charge-symmetric contributions at leading order in QCD. Therefore, using specific kinematic features of the signal, we construct a charge asymmetry in the dilepton final state which - due also to a reduction of systematic uncertainties in the asymmetry - is potentially sensitive to Vtd suppressed effects. In particular, using signal and background simulations up to the detector level, we show that this new observable could already improve the current direct upper bound on |Vtd| with existing LHC data. We also project that |Vtd| values down to ∼10 times the standard model prediction could be probed at the high-luminosity LHC.Fil: Alvarez, Ezequiel.

Experimental assessment of molecular markers efficiency (VvAGL11) in mas for table grape breeding
No full textA two-year mosquito survey focusing on Aedes koreicus in northern Italy and implications for adult trapping
No full textAedes koreicus (Edwards) is an invasive mosquito species, like Aedes albopictus (Skuse) and Aedes japonicus japonicus (Theobald), that has already colonized a large part of northeastern Italy and other European countries. Despite its rapid expansion, information about adult distribution and trapping is lacking. Here, we conducted a two-year longitudinal survey using adult traps to investigate the spatio-temporal distribution of Ae. koreicus and evaluated the effectiveness of three trapping devices in Latin-square experiments conducted in an urban site and a forested site. Three different traps were compared: a CO2 baited Biogents Sentinel trap (BG trap), a CO2-baited Centers for Disease Control and Prevention light trap (CDC trap) and a gravid trap baited with a grass infusion.
In northern Italy, Ae. koreicus was collected from late April to early November with a peak of abundance in August. In 2015, Ae. koreicus was more abundant than in 2014 due to higher temperatures during summer. Unlike Ae. albopictus, Ae. koreicus abundance was not related to the altitude of the sampling locations in the range 241-660 m a.s.l. The BG trap and the gravid trap collected significantly more Ae. koreicus than the CDC trap in the urban site, whereas there was no significant difference between the three traps in the forested site. In the urban site, the BG trap and the gravid trap were the most effective for collecting Ae. albopictus and Culex pipiens L., respectively. In the forested site, Cx. pipiens was primarily collected by the CDC trap
Improvement in breakdown characteristics with multiguard structures in microstrip silicon detectors for CMS
No full textTo obtain full charge collection the CMS silicon detectors should be able to operate at high bias voltage. We observed that multiguard structures enhance the breakdown performance of the devices on several tens of baby detectors designed for CMS. The beneficial effects of the multiguard structures still remains after the strong neutron irradiation performed to simulate the operation at the LHC
Fragmentation of jets containing a prompt J/psi meson in PbPb and pp collisions at sqrt(s_NN) = 5.02 TeV
No full textJets containing a prompt J/psi meson are studied in lead-lead collisions at a nucleon-nucleon center-of mass energy of 5.02 TeV, using the CMS detector at the LHC. Jets are selected to be in the transverse momentum range of 30 <= pT <= 40 GeV. The J/psi yield in these jets is evaluated as a function of the jet fragmentation variable z, the ratio of the J/psi T-p to the jet p(T). The nuclear modification factor, R-AA, is then derived by comparing the yield in lead-lead collisions to the corresponding expectation based on proton-proton data, at the same nucleon-nucleon center-of-mass energy. The suppression of the J/psi yield shows a dependence on z, indicating that the interaction of the J/psi with the quark-gluon plasma formed in heavy ion collisions depends on the fragmentation that gives rise to the J/psi meson.
