Violation of the equivalence principle from light scalar dark matter

2018

In this paper, we study the local observational consequences of a violation of the Einstein Equivalence Principle induced by models of light scalar Dark Matter (DM). We focus on two different models where the scalar field couples linearly or quadratically to the standard model of matter fields. For both these cases, we derive the solutions of the scalar field. We also derive from first principles the expressions for two types of observables: (i) the local comparison of two atomic sensors that are differently sensitive to the constants of Nature and (ii) the local differential acceleration between two test-masses with different compositions. For the linear coupling, we recover that the signa…

Tools to identify nutritional risk for older people in the home

2012

Author's version of an article in the journal: British Journal of Community Nursing. Community nurses are in an ideal position to identify older home-dwelling people at nutritional risk and thereby to prevent undernutrition. The aim of this paper is to present some nutritional screening instruments for older home-dwelling people and to discuss nutritional issues of importance for community nurses in order to assess nutritional risk and prevent undernutrition. The screening instruments Nutritional Form For the Elderly (NUFFE) and Mini Nutritional Assessment (MNA) are especially developed for screening older people. The Malnutrition Universal Screening Tool (MUST) is recommended for screening…

Giacomo Serpotta nella chiesa di Sant'Orsola di Palermo. Studi e restauro

2011

La monografia affronta in maniera interdisciplinare un'opera meno nota di Giacomo Serpotta, realizzata tra il 1695 e il 1696, all'interno della chiesa palermitana di Sant'Orsola. A dispetto dell'apparente consistenza come apparato minore, lo studio e il restauro, intersecando le conoscenze acquisite durante il cantiere, hanno posto in evidenza aspetti meno divulgati sia relativi alla tecnica, che all'iconografia (anche relativamente ad inediti modelli di riferimento), che all'interpretazione delle immagini simboliche. La ricerca, anche con il rinvenimento di documentazione inedita d'archivio, ha fissato le coordinate cronologiche dell'apparato plastico, in relazione al sito e alla produzion…

Agder Living Lab: From Ideas to Large-Scale Deployment and Long-Term User Adoption of Inclusive Health Solutions

2016

End-user involvement is a central part in the strategy of public and private organisations to generate user-driven innovative solutions to real-world problems. The Living lab concept is an instrument to create user-centered solutions, with almost 400 recognized in the European Network of Living Labs (ENoLL) since 2006. Living labs cover diverse topics, such as smart-cities, innovative learning and digital health. A national initiative in Southern Norway has funded the Agder Living Lab (ALL) for eHealth, a user-centered innovation environment participated by multisectorial public and private partners. ALL implements a quadruple-helix model represented by citizens, industry, academia and gove…

Le grandi esposizioni : territori dell’immaginario

2010

Since their appearance, from the first exhibition in London in 1851 to the future in Milan in 2015, we still wonder about the aim of these events. Their role changed, some skills lose their value, and others appeared. Few works focuses on this subject, of which we get sometime only the impetus for the host country to recreate her international image, when, on the contrary, those events become leading urban tools from one continent to another. Which are the principles which support them today? Who decides on their organization? Which regulations govern them? Which are the repercussions on the host town? Curiously, the great contemporary exhibitions have been little studied under these aspect…

Physics beyond colliders at CERN: beyond the Standard Model working group report

2019

The Physics Beyond Colliders initiative is an exploratory study aimed at exploiting the full scientific potential of the CERN's accelerator complex and scientific infrastructures through projects complementary to the LHC and other possible future colliders. These projects will target fundamental physics questions in modern particle physics. This document presents the status of the proposals presented in the framework of the Beyond Standard Model physics working group, and explore their physics reach and the impact that CERN could have in the next 10–20 years on the international landscape.

K− over K+ multiplicity ratio for kaons produced in DIS with a large fraction of the virtual-photon energy

2018

The K$^{-}$ over K$^{+}$ multiplicity ratio is measured in deep-inelastic scattering, for the first time for kaons carrying a large fraction $z$ of the virtual-photon energy. The data were obtained by the COMPASS collaboration using a 160 GeV muon beam and an isoscalar $^6$LiD target. The regime of deep-inelastic scattering is ensured by requiring $Q^2>1$ (GeV/$c)^2$ for the photon virtuality and $W>5$ GeV/$c^2$ for the invariant mass of the produced hadronic system. Kaons are identified in the momentum range from 12 GeV/$c$ to 40 GeV/$c$, thereby restricting the range in Bjorken-$x$ to $0.010.75$. For very large values of $z$, $i.e.$ $z>0.8$, we observe the kaon multiplicity ratio to fall …

Hepatitis B core particles as a universal display model: a structure-function basis for development

1999

AbstractBecause it exhibits a remarkable capability to accept mutational intervention and undergo correct folding and self-assembly in all viable prokaryotic and eukaryotic expression systems, hepatitis B core (HBc) protein has been favored over other proposed particulate carriers. Structurally, the unusual α-helical organization of HBc dimeric units allows introduction of foreign peptide sequences into several areas of HBc shells, including their most protruding spikes. Progress toward full resolution of the spatial structure as well as accumulation of chimeric HBc-based structures has brought closer the knowledge-based design of future vaccines, gene therapy tools and other artificial par…

Impact of dijet and D-meson data from 5.02 TeV p+Pb collisions on nuclear PDFs

2020

We discuss the new constraints on gluon parton distribution function (PDF) in lead nucleus, derivable with the Hessian PDF reweighting method from the 5.02 TeV p+Pb measurements of dijet (CMS) and $D^0$-meson (LHCb) nuclear modification ratios. The impact is found to be significant, placing stringent constraints in the mid- and previously unconstrained small-$x$ regions. The CMS dijet data confirm the existence of gluon anti-shadowing and the onset of small-$x$ shadowing, as well as reduce the gluon PDF uncertainties in the larger-$x$ region. The gluon constraints from the LHCb $D^0$ data, reaching down to $x \sim 10^{-5}$ and derived in a NLO perturbative QCD approach, provide a remarkable…
