Abstract The JET 2019–2020 scientific and technological programme exploited the results of years concerted engineering work, including ITER-like wall (ILW: Be W divertor) installed in 2010, improved diagnostic capabilities now fully available, a major neutral beam injection upgrade providing record power 2019–2020, tested technical procedural preparation for safe operation with tritium. Research along three complementary axes yielded wealth new results. Firstly, plasma delivered scenarios...
Abstract In 2021 JET exploited its unique capabilities to operate with T and D–T fuel an ITER-like Be/W wall (JET-ILW). This second major campaign (DTE2), after DTE1 in 1997, represented the culmination of a series enhancements—new fusion diagnostics, new injection capabilities, refurbishment plant, increased auxiliary heating, in-vessel calibration 14 MeV neutron yield monitors—as well as significant advances plasma theory modelling community. DTE2 was complemented by sequence isotope...
The 2014–2016 JET results are reviewed in the light of their significance for optimising ITER research plan active and non-active operation. More than 60 h plasma operation with first wall materials successfully took place since its installation 2011. New multi-machine scaling type I-ELM divertor energy flux density to is supported by principle modelling. relevant disruption experiments modelling reported a set three mitigation valves mimicking setup.

Abstract For the past several years, JET scientific programme (Pamela et al 2007 Fusion Eng. Des . 82 590) has been engaged in a multi-campaign effort, including experiments D, H and T, leading up to 2020 first with 50%/50% D–T mixtures since 1997 ever plasmas ITER mix of plasma-facing component materials. this purpose, concerted physics technology was launched view prepare campaign (DTE2). This paper addresses key elements developed by directly contributing preparation. intense preparation...
There is experimental evidence that the neuronal network in some areas of brain cortex presents scale-free property, i.e., neuron connectivity distributed according to a power law, such neurons are more likely couple with other already well-connected ones. From information processing point view, it relevant bursting activity be synchronized weak sense. A coherent output coupled can described through chaotic phase synchronization their activity. We investigated this phenomenon using...
We investigate the collective dynamics of bursting neurons on clustered networks. The network model is composed subnetworks, each them presenting so-called small-world property. This can also be regarded as a In subnetwork neuron connected to other ones with regular well random connections, latter given intracluster probability. Moreover, in has an intercluster probability subnetworks. local two time scales (fast and slow) modeled by two-dimensional map. such parameters are chosen slightly...
The objective of thermonuclear fusion consists producing electricity from the coalescence light nuclei in high temperature plasmas. most promising route to envisages confinement such plasmas with magnetic fields, whose studied configuration is tokamak. Disruptions are catastrophic collapses affecting all tokamak devices and one main potential showstoppers on a commercial reactor. In this work we report how, deploying innovative analysis methods thousands JET experiments covering isotopic...
Functional brain networks are composed of cortical areas that anatomically and functionally connected. One the for which more information is available in literature cat cerebral cortex. Statistical analyses latter suggest its structure can be described as a clustered network, each cluster scale-free network possessing highly connected hubs. Those hubs are, on their hand, together strong fashion (“rich-club” network). We have built inspired cortex so to study dynamical properties. In this...
We study three different strategies of vaccination in an SEIRS (Susceptible–Exposed–Infected–Recovered–Susceptible) seasonal forced model, which are (i) continuous vaccination; (ii) periodic short-time localized vaccination, and (iii) pulsed width campaign. Considering the first strategy, we obtain expression for basic reproduction number infer a minimum rate necessary to ensure stability disease-free equilibrium (DFE) solution. In second short duration pulses added constant baseline rate....

Excessively high, neural synchronization has been associated with epileptic seizures, one of the most common brain diseases worldwide. A better understanding mechanisms can thus help control or even treat epilepsy. In this paper, we study in a random network where nodes are neurons excitatory and inhibitory synapses, activity for each node is provided by adaptive exponential integrate-and-fire model. framework, verify that decrease influence inhibition generate originating from pattern...
Thermally sensitive neurons present bursting activity for certain temperature ranges, characterized by fast repetitive spiking of action potential followed a short quiescent period. Synchronization is possible in networks coupled neurons, and it sometimes an undesirable feature. Control procedures can suppress totally or partially this collective behavior, with applications deep-brain stimulation techniques. We investigate the control synchronization small-world Hodgkin-Huxley-type thermally...
