Forward doubly-virtual Compton scattering off the nucleon in chiral perturbation theory: The subtraction function and moments of unpolarized structur…

2020

The forward doubly-virtual Compton scattering (VVCS) off the nucleon contains a wealth of information on nucleon structure, relevant to the calculation of the two-photon-exchange effects in atomic spectroscopy and electron scattering. We report on a complete next-to-leading-order (NLO) calculation of low-energy VVCS in chiral perturbation theory ($\chi$PT). Here we focus on the unpolarized VVCS amplitudes $T_1(\nu, Q^2)$ and $T_2(\nu, Q^2)$, and the corresponding structure functions $F_1(x, Q^2)$ and $F_2(x,Q^2)$. Our results are confronted, where possible, with "data-driven" dispersive evaluations of low-energy structure quantities, such as nucleon polarizabilities. We find significant dis…

The Short-Access Mother–Baby-(SAMBA) Cholangioscopy System

2014

Conventional mother–baby cholangioscopy systems have significant limitations including poor image resolution, limited maneuverability and fragile cholangioscopes. We propose the novel short-access mother–baby-(SAMBA) cholangioscopy system that involves a very short and flexible cholangioscope that is introduced in a dedicated mother duodenoscope with an extra distal side port. Clinical feasibility of this device is demonstrated in three complex cases with cholangiopathies. The strengths of SAMBA cholangioscopy are improved imaging quality and excellent maneuverability of the baby that allows access of small intrahepatic ducts. Evaluation of suspected intrahepatic biliary disease is an excel…

Genome-wide association analysis in primary sclerosing cholangitis identifies two non-HLA susceptibility loci

2011

Primary sclerosing cholangitis (PSC) is a chronic bile duct disease affecting 2.4-7.5% of individuals with inflammatory bowel disease. We performed a genome-wide association analysis of 2,466,182 SNPs in 715 individuals with PSC and 2,962 controls, followed by replication in 1,025 PSC cases and 2,174 controls. We detected non-HLA associations at rs3197999 in MST1 and rs6720394 near BCL2L11 (combined P = 1.1 x 10(-16) and P = 4.1 x 10(-8), respectively).

2021

Introduction: Digital health technologies such as self-monitoring devices and apps are becoming increasingly important as tools to promote healthy habits and support individuals in their self-care. There is still a scarcity of research that builds on motivational theory to better understand the functioning of digital health technologies. The self-determination theory (SDT) is a macro theory of motivation that delineates three basic psychological needs that are linked to different types of motivation and lead to well-being when satisfied and illbeing when frustrated.Objective: To explore how the use of a digital tool for self-monitoring and communication with healthcare satisfies or frustrat…

Channel Switching Protocols Hinder the Transition to IP World: The Pentagon Story

2019

In this paper, we target the strategy for telecommunications architectures during the transition to the IP-only models. The paper discusses the shifting from circuit switching to packet switching in telecommunications. Particularly, we analyze the coexistence of circuit switching and packet switching technologies in American military communications where each warfare object should have own IP address. The paper discusses the role of multifunction Soft Switches (MFSS). This Soft Switch plays the role of a media gateway between TDM channels and IP channels. As a case, we are passing through the transformation from SS7 signaling to internet protocol, ISDN-based government Defense Red Switch Ne…

Seguridad digital: actuaciones pedagógicas en los niveles de ESO en el contexto valenciano

2015

El propósito de este trabajo es localizar y clasificar las prácticas pedagógicas orientadas al uso responsable de las tecnologías en centros de Educación Secundaria Obligatoria en la Comunidad Valenciana. El enfoque desde el que nos proponemos analizar las prácticas de uso, es el que concibe a la ciudadanía digital como activa y participativa, competencias para la que se ha de formar. Siguiendo las fases establecidas, se elaborará un material educativo atendiendo a las necesidades detectadas durante el estudio. Para la recogida de información, diseñamos un instrumento de evaluación donde se analizan los objetos de aprendizaje seleccionados en la muestra. En la presente comunicación exponemo…

Media Literacy in I taly

2019

In Italy, the media literacy (ML) movement has a long grassroots tradition. Main actors are from civil society (academics, associations, church communities, teachers, media professionals, educators), with some growing support from local and national institutions. While digital literacy has stably entered the school system through funds, projects, and teaching resources aimed at improving students' digital skills, only recently has a more sociocultural view of digital technologies developed, thanks also to the National Plan for Digital School issued by the Ministry of Education in 2015. For the future, more commitment to developing the following three important directions is needed: conducti…

Centralization and decentralization are key concepts in debates that focus on the (anti)democratic character of digital societies. Centralization is understood as the control over communication and data flows, and decentralization as giving it (back) to users. Communication and media research focuses on centralization put forward by dominant digital media platforms, such as Facebook and Google, and governments. Decentralization is investigated regarding its potential in civil society, i.e., hacktivism, (encryption) technologies, and grass-root technology movements. As content-based media companies increasingly engage with technology, they move into the focus of critical media studies. Moreo…
