Persistence in complex systems
2022
Persistence is an important characteristic of many complex systems in nature, related to how long the system remains at a certain state before changing to a different one. The study of complex systems' persistence involves different definitions and uses different techniques, depending on whether short-term or long-term persistence is considered. In this paper we discuss the most important definitions, concepts, methods, literature and latest results on persistence in complex systems. Firstly, the most used definitions of persistence in short-term and long-term cases are presented. The most relevant methods to characterize persistence are then discussed in both cases. A complete literature r…
Toward learning autonomous pallets by using fuzzy rules, applied in a Conwip system
2012
Published version of an article in the journal: The International Journal of Advanced Manufacturing Technology. Also available from the publisher at: http://dx.doi.org/10.1007/s00170-012-4057-8 Nowadays, material planning and control strategies are becoming continuously complex tasks spanning from individual plants to logistic networks. In fact, this is the consequence of increasing intricacy in product variants and their respective convolution in networks’ structures. Customers ask for specific products with individual characteristics that force companies for more clever performances by more flexibility. For doing so, the existing planning and control systems, which work based on central m…
Emotional modulation of the attentional blink and the relation to interpersonal reactivity
2013
The extent of the attentional blink effect on detection rates in rapid serial visual presentations is modulated by the emotionality of the stimuli. Emotionally salient stimuli are detected more often, even if presented in the attentional blink period, and elicit an enlarged P3 response, which has been interpreted as enhanced consolidation. This effect correlates with individual differences in trait affectivity such as anxiety or dysphoria. Here, we ask if it is also related to the capacity to detect emotions in others, i.e., to interpersonal social traits. We therefore presented emotional and neutral images depicting social scenes as targets in an attentional blink design and measured detec…
Environmental evidence of Valencia lagoon coastal barrier stabilization from 8500 BP to Present. Climate and eustatic variations
2020
Abstract The Albufera de Valencia is one of the largest lagoon in the Spanish Mediterranean. Two continuous borehole cores reaching depths of 8 and 14 m in the northern part of the lagoon underwent sedimentological, micropaleontological and biological study. The organic content was also analysed, and 14C radiometric dating and amino acid racemization were performed. Study of the content of benthic foraminifera and n-alkanes and alkanoic acids in the lagoon sedimentary record identified several periods. The core records showed seven different environments: alluvial; freshwater marsh; brackish marsh; brackish lagoon; brackish lagoon with marine connection, backbarrier flat, and backshore. The…
Mobility of plume-derived volcanogenic elements in meteoric water at Nyiragongo volcano (Congo) inferred from the chemical composition of single rain…
2017
The chemical composition of single rainfall events was investigated at Nyiragongo volcano (Democratic Republic of Congo) with the aim of determining the relative contributions of plume-derived elements. The different locations of the sampling sites allowed both plume-affected samples (hereafter referred to as “fumigated samples”) and samples representative of the local background to be collected. The chemical composition of the local background reflects the peculiar geographic features of the area, being influenced by biomass burning, geogenic dust, and biological activity. Conversely, fumigated samples contain large amounts of volcanogenic elements that can be clearly distinguished from th…

Polkujuoksu : juoksuharrastus kohtaa luontokokemuksen
2017
Juoksuharrastuksesta eriytynyt polkujuoksu on suosiotaan vahvasti 2010-luvulla kasvattanut liikuntamuoto. Käsillä oleva tutkimus on ensimmäinen suomalaista polkujuoksuharrastusta kartoittava liikuntasosiologinen tutkimus. Polkujuoksuharrastusta taustoitetaan teoreettisesti vapaa-ajan elämäntavan, luontoliikunnan sekä kestävyysliikunnan ilmiönä. Tutkimukselle on asetettu neljä tutkimuskysymystä: 1) Ketkä harrastavat polkujuoksua? 2) Miten polkujuoksua harrastetaan? 3) Kuinka kiinnittyneitä polkujuoksun harrastajat ovat harrastukseensa? 4) Miten polkujuoksijat haluaisivat liikuntamuodon kehittyvän? Polkujuoksun harrastajakartoitus toteutettiin määrällisenä tutkimuksena. Tutkimusta varten laad…
Ischemia Cardiaca e Psicosomatica: ruolo di eventi stressanti e stili di vita
2009
Objective: the aim of our study was to evaluate the role of stressful events, lifestyles and various socio-environmental factors in the beginning of ischemic cardiac diseases, together with cardiovascular factors. Materials and methods: 64 patients with recent cardiac ischemia and 64 controls matched 1:1, according to their sex and age, have been evaluated. The study required the filling in of clinico-anamnestic reports and the evaluation of stressful events, using the Holmes Rahe scale. Results: in the 44% of the patients who had a heart ischemia, an emotional striking event occurred few day before, with a 28% incidence of work and family problems. The mean score of the Holmes Social Readj…
Grazoprevir/elbasvir for the immediate treatment of recently acquired HCV genotype 1 or 4 infection in MSM.
2020
Abstract Background In Europe, increases in HCV infection have been observed over the last two decades in MSM, making them a key population for recently acquired HCV. Alternative combinations of direct-acting antiviral agents against early HCV infection need to be assessed. Patients and methods In this pilot trial, MSM with recently acquired genotype 1 or 4 HCV infection were prospectively included and received 8 weeks of oral grazoprevir 100 mg and elbasvir 50 mg in a fixed-dose combination administered once daily. The primary endpoint was sustained virological response evaluated 12 weeks after the end of treatment (EOT) (SVR12). Secondary endpoints were the virological characterization of…
