Phase diagram of QCD in strong background magnetic field

We discuss the phase diagram of QCD in the presence of a strong background magnetic field, providing numerical evidence, based on lattice simulations of QCD with $2+1$ flavours and physical quark masses, that the QCD crossover turns into a first order phase transition for large enough magnetic field, with a critical endpoint located between $eB=4$ GeV$^2$ (where we found an analytic crossover at a pseudo-critical temperature $T_c=(98\pm3)$ MeV) and $eB=9$ GeV$^2$ (where the measured critical temperature is $T_c=(63\pm5)$ MeV).Comment: 6 pages, 8 figures; contribution to the proceedings of the International Conference on High Energy Physics (ICHEP 2022), July 6-13, 2022, Bologna (Italy

This tutorial includes the guidelines to build distributed applications where clients may interact with physical space. Inter-client interaction occurs through a semantic event processing engine. Information interoperability is based on a shared knowledge representation model named ontology. This tutorial is focused on client design and on the SPARQL primitives that provide the means for client-event processing engine interaction

An Integrated Framework to Achieve Interoperability in Person-Centric Health Management

The need for high-quality out-of-hospital healthcare is a known socioeconomic problem. Exploiting ICT's evolution, ad-hoc telemedicine solutions have been proposed in the past. Integrating such ad-hoc solutions in order to cost-effectively support the entire healthcare cycle is still a research challenge. In order to handle the heterogeneity of relevant information and to overcome the fragmentation of out-of-hospital instrumentation in person-centric healthcare systems, a shared and open source interoperability component can be adopted, which is ontology driven and based on the semantic web data model. The feasibility and the advantages of the proposed approach are demonstrated by presenting the use case of real-time monitoring of patients' health and their environmental context

RedSib: A smart-M3 semantic information broker implementation

Smart-M3 is an open source middleware solution originally released by Nokia as a prototype reference infrastructure to support context-aware ontology-driven smart applications. This paper proposes a renewedSmart-M3 Semantic Information Broker implementation with increased performance and usability levels. In the proposed solution many features have been added or modified, preserving compatibility with the previous release. The major changes are related to the subscription mechanism, the RDF store and the supported encodings for information representation and query. SPARQL query language replaces Wilbur. This paper enlightens the analysis carried out on the original implementation and discusses the choices made to increase its maturity level. The work done is a step forward towards a stable and efficient open interoperability platform for the emerging market of smart space based services

The M3 architecture for smart spaces: Overview of semantic information broker implementations

A smart space enhances a networked computing environment by enabling information sharing for a multitude of local digital devices and global resources from the Internet. We consider the M3 architecture (multi-device, multi-vendor, multi-domain) for creating smart spaces, which integrates technologies from two innovative concepts: the Semantic Web and the Internet of Things. Our research focus is on analyses of the capabilities of Smart-M3 platform, which provides software implementations for such a central element of an M3 smart space as Semantic Information Broker (SIB). The paper presents a state-of-the-art and contributes our systematized vision on the SIB design and implementation. The analyzed open source SIB implementations include the original Smart-M3 piglet-based SIB, its optimized descendant RedSIB, OSGi SIB for Java devices, pySIB for Python devices, and CuteSIB for Qt devices. We also analyze the design of proprietary or incomplete SIB implementations: RIBS for embedded devices and ADK SIB built upon the OSGi framework with integration in the Eclipse Integrated Development Environment. The theoretical study is augmented with experimental evaluation of available SIB implementations

Development of collaborative editing applications through semantic publish-subscribe platforms

Cloud computing revolutionized the way resources (i.e. services and data) are accessed and used. Among the many changes in data processing and service provision paradigms, Software as a Service (SaaS) and collaborative editing are two of the most significant. This paper presents an approach based on semantic publish/subscribe paradigm to the development of collaborative editing applications. The main aim of this research work consists in exploiting emerging technologies (i.e. semantic web data representation formalisms, publish-subscribe platforms) in order to (1) overcome limitations coming from the traditional paradigm of single-author workflows, (2) enhance the editing capabilities of the users, (3) ease the development and maintainment of applications and (4) provide a shared high- level abstraction of the documents that fosters information-level interoperability and reusability. The proposed approach is then validated through an ad-hoc vector graphics application, SCEd (Semantic Collaborative Editor) built upon a SPARQL Event Processing Architecture derived from the Smart-M3 semantic publish-subscribe platform

Comparación de columna total de ozono OMI-DOAS con mediciones terrestres en Argentina

Total ozone column (TOC) measurements through the Ozone Monitoring Instrument (OMI/NASA EOSAura) are compared with ground-based observations made using Dobson and SAOZ instruments for the period 2004–2019 and 2008–02/2020, respectively. The OMI data were inverted using the Differential Optical Absorption Spectroscopy algorithm (overpass OMI-DOAS). The four ground-based sites used for the analysis are located in subpolar and subtropical latitudes spanning from 34°S to 54°S in the Southern Hemisphere, in the Argentine cities of Buenos Aires (34.58°S, 58.36°W; 25 m a.s.l.), Comodoro Rivadavia (45.86°S, 67.50°W; 46 m a.s.l.), Río Gallegos (51.60°S, 69.30°W; 72 m a.s.l.) and Ushuaia (54.80°S, 68.30°W; 14 m a.s.l.). The linear regression analyzes showed correlation values greater than 0.90 for all sites. The OMI measurements revealed an overestimation of less than 4 % with respect to the Dobson instruments, while the comparison with the SAOZ instrument presented a very low underestimation of less than 1 %.En este trabajo se comparan mediciones de columna total de ozono (CTO) del Ozone Monitoring Instrument (OMI/NASA EOS-Aura), con observaciones terrestres de instrumentos Dobson y SAOZ para el periodo 2004–2019 y 2008–02/2020, respectivamente.

Psychophysical benefits of recreational five-a-side football

Nowadays, recreational sports activities are focused on health and wellness aspects for a physiological study on the effects of the elite sport due to the spread of recreational sport, especially football. This work addresses the physical benefits originated from recreational five-a-side football and aims at the perceptions about self-evaluation of the physical and the psychological data. It also proposes a questionnaire in a group of young men aged 23 to 29 who played amateur five-a-side football for 8 weeks just 2-3 times a week. The requests basing on the overall research conclusions on the studies performed on recreational football (Kustrup et al., 2010). The most significant results showed that practicing amateur sports activities makes you feel better both physically and psychologically (respectively 87,3% e 93,3% of the answers) and it is less tiring and stressful than playing football agonistically (respectively 80% e 80% of the answers) or practicing strength training or interval running training. Furthermore, according to the data complex, it can be potentially satisfactory from the point of the view healthy and well-ness sport that can improve general well-being and it can prevent lethal diseases, such as cardiovascular diseases and obesity. In conclusion, it can be affirmed that recreational five-a-side football can produce not only physical benefits, as Kustrup's article shows, but also significant psychological benefits, which makes you feel better and more relaxed

Impact of Interdisciplinary Research on Planning, Running, and Managing Electromobility as a Smart Grid Extension

The smart grid is concerned with energy efficiency and with the environment, being a countermeasure against the territory devastations that may originate by the fossil fuel mining industry feeding the conventional power grids. This paper deals with the integration between the electromobility and the urban power distribution network in a smart grid framework, i.e., a multi-stakeholder and multi-Internet ecosystem (Internet of Information, Internet of Energy, and Internet of Things) with edge computing capabilities supported by cloud-level services and with clean mapping between the logical and physical entities involved and their stakeholders. In particular, this paper presents some of the results obtained by us in several European projects that refer to the development of a traffic and power network co-simulation tool for electro mobility planning, platforms for recharging services, and communication and service management architectures supporting interoperability and other qualities required for the implementation of the smart grid framework. For each contribution, this paper describes the inter-disciplinary characteristics of the proposed approaches
