A Novel Bio-Inspired Approach for High-Performance Management in Service-Oriented Networks

2021

Service-continuity in distributed computing can be enhanced by designing self-organized systems, with a non-fixed structure, able to modify their structure and organization, as well as adaptively react to internal and external environment changes. In this paper, an architecture exploiting a bio-inspired management approach, i.e., the functioning of cell metabolism, for specialized computing environments in Service-Oriented Networks (SONs) is proposed. Similar to the processes acting in metabolic networks, the nodes communicate to each other by means of stimulation or suppression chains giving rise to emergent behaviors to defend against foreign invaders, attacks, and malfunctioning. The mai…

Robustness of asymmetry and coherence of quantum states

2016

Quantum states may exhibit asymmetry with respect to the action of a given group. Such an asymmetry of states can be considered as a resource in applications such as quantum metrology, and it is a concept that encompasses quantum coherence as a special case. We introduce explicitly and study the robustness of asymmetry, a quantifier of asymmetry of states that we prove to have many attractive properties, including efficient numerical computability via semidefinite programming, and an operational interpretation in a channel discrimination context. We also introduce the notion of asymmetry witnesses, whose measurement in a laboratory detects the presence of asymmetry. We prove that properly c…

Mometasone furoate delivered via Breezhaler and Twisthaler in patients with asthma

2019

Introduction: Mometasone furoate (MF), an inhaled corticosteroid (ICS), is approved for the treatment of asthma. Previous studies suggest that MF Twisthaler® doses of 800 and 200 µg and MF Breezhaler® doses of 320 and 80 µg would elicit similar lung function effects, respectively. These MF doses are also used in an indacaterol/MF combination in development for asthma. Since sensitivity to ICS is variable, individual patients’ ICS sensitivity (as measured by FEV1 decline on ICS weaning) was used to build a robust analysis model for the study data. Methods: This was a randomized, double-blind, double-dummy, parallel-group, non-inferiority study of 739 adolescents and adults with asthma. MF wa…

Longitudinal metagenomics

2018

Culture-independent approaches are revolutionizing biology. Whether in a clinical or in an environmental sample, metagenomics can reveal which microorganisms exist and what they actually do. Metagenomic studies have unveiled more microbial diversity in a few years than traditional microbiology in centuries. From the top branches down to the roots, its discoveries are reshaping the tree of life dramatically. Metagenomics is a powerful tool for the study of microbial communities, but it requires equally powerful methods of analysis. Current challenges in the analysis of metagenomic data include the accurate comparison of samples, the estimation of the uncertainty in the results, and the effec…

Museums as participants in the market game: The political and economic context of the functioning of the museums

2017

Under the influence of contemporary social and political changes, which have resulted in, inter alia, changes in the structure of museum audiences and their expectations, museums have had to implement new practices and tools which were previously not present in their fields of interest. these processes changed the definition of the mission of a contemporary museum and the way of ommunicating with participants of culture. today a museum, like every other institution on the entertainment and leisure market, has to attract recipients of its offer. Museums thus engage in ever more close relationships with the field of economy. Moreover, the model of public financing of culture subjects the acti…

La combustione HCCI mediante miscele di gas naturale e benzina: una prima esperienza sperimentale

2016

Si presentano in questo articolo i risultati di una sperimentazione volta a valutare la possibilità di effettuare una combustione HCCI (Homogeneous Charge Compression Ignition) stabile mediante l’impiego di miscele di gas naturale (GN) e benzina. La combustione HCCI ha ottime prerogative di basso impatto ambientale, ma la sua realizzazione pone qualche problema di stabilità al variare delle condizioni di carico richieste al motore: lo studio condotto mostra come l’impiego di miscele di GN e benzina, la cui composizione permette di variarne la resistenza all’autoaccensione, consente di ampliare il campo di funzionamento stabile della combustione HCCI. In the last decade the HCCI combustion h…

A New Simple Function for Combustion and Cyclic Variation Modeling in Supercharged Spark Ignition Engines

2022

Research in the field of Internal Combustion (IC) engines focuses on the drastic reduction of both pollutant and greenhouse gas emissions. A promising alternative to gasoline and diesel fuel is represented by the use of gaseous fuels, above all green hydrogen but also Natural Gas (NG). In previous works, the authors investigated the performance, efficiency, and emissions of a supercharged Spark Ignition (SI) engine fueled with mixtures of gasoline and natural gas; a detailed research involving the combustion process of this kind of fuel mixture has been previously performed and a lot of experimental data have been collected. Combustion modeling is a fundamental tool in the design and optimi…
