Overview of recent TJ-II stellarator results
The main results obtained in the TJ-II stellarator in the last two years are reported. The most important topics investigated have been modelling and validation of impurity transport, validation of gyrokinetic simulations, turbulence characterisation, effect of magnetic configuration on transport, fuelling with pellet injection, fast particles and liquid metal plasma facing components. As regards impurity transport research, a number of working lines exploring several recently discovered effects have been developed: the effect of tangential drifts on stellarator neoclassical transport, the impurity flux driven by electric fields tangent to magnetic surfaces and attempts of experimental validation with Doppler reflectometry of the variation of the radial electric field on the flux surface. Concerning gyrokinetic simulations, two validation activities have been performed, the comparison with measurements of zonal flow relaxation in pellet-induced fast transients and the comparison with experimental poloidal variation of fluctuations amplitude. The impact of radial electric fields on turbulence spreading in the edge and scrape-off layer has been also experimentally characterized using a 2D Langmuir probe array. Another remarkable piece of work has been the investigation of the radial propagation of small temperature perturbations using transfer entropy. Research on the physics and modelling of plasma core fuelling with pellet and tracer-encapsulated solid-pellet injection has produced also relevant results. Neutral beam injection driven Alfvénic activity and its possible control by electron cyclotron current drive has been examined as well in TJ-II. Finally, recent results on alternative plasma facing components based on liquid metals are also presented. ISSN:0029-5515 ISSN:1741-432

Dietary αâLinolenic Acid, Marine Ïâ3 Fatty Acids, and Mortality in a Population With High Fish Consumption: Findings From the PREvenciĂłn con DIeta MEDiterrĂĄnea (PREDIMED) Study
Background: Epidemiological evidence suggests a cardioprotective role of αâlinolenic acid (ALA), a plantâderived Ïâ3 fatty acid. It is unclear whether ALA is beneficial in a background of high marine Ïâ3 fatty acids (longâchain nâ3 polyunsaturated fatty acids) intake. In persons at high cardiovascular risk from Spain, a country in which fish consumption is customarily high, we investigated whether meeting the International Society for the Study of Fatty Acids and Lipids recommendation for dietary ALA (0.7% of total energy) at baseline was related to allâcause and cardiovascular disease mortality. We also examined the effect of meeting the society's recommendation for longâchain nâ3 polyunsaturated fatty acids (â„500 mg/day). Methods and Results: We longitudinally evaluated 7202 participants in the PREvenciĂłn con DIeta MEDiterrĂĄnea (PREDIMED) trial. Multivariableâadjusted Cox regression models were fitted to estimate hazard ratios. ALA intake correlated to walnut consumption (r=0.94). During a 5.9ây followâup, 431 deaths occurred (104 cardiovascular disease, 55 coronary heart disease, 32 sudden cardiac death, 25 stroke). The hazard ratios for meeting ALA recommendation (n=1615, 22.4%) were 0.72 (95% CI 0.56â0.92) for allâcause mortality and 0.95 (95% CI 0.58â1.57) for fatal cardiovascular disease. The hazard ratios for meeting the recommendation for longâchain nâ3 polyunsaturated fatty acids (n=5452, 75.7%) were 0.84 (95% CI 0.67â1.05) for allâcause mortality, 0.61 (95% CI 0.39â0.96) for fatal cardiovascular disease, 0.54 (95% CI 0.29â0.99) for fatal coronary heart disease, and 0.49 (95% CI 0.22â1.01) for sudden cardiac death. The highest reduction in allâcause mortality occurred in participants meeting both recommendations (hazard ratio 0.63 [95% CI 0.45â0.87]). Conclusions: In participants without prior cardiovascular disease and high fish consumption, dietary ALA, supplied mainly by walnuts and olive oil, relates inversely to allâcause mortality, whereas protection from cardiac mortality is limited to fishâderived longâchain nâ3 polyunsaturated fatty acids.

Experimental confirmation of efficient island divertor operation and successful neoclassical transport optimization in Wendelstein 7-X
We present recent highlights from the most recent operation phases of Wendelstein 7-X, the most advanced stellarator in the world. Stable detachment with good particle exhaust, low impurity content, and energy confinement times exceeding 100Â ms, have been maintained for tens of seconds. Pellet fueling allows for plasma phases with reduced ion-temperature-gradient turbulence, and during such phases, the overall confinement is so good (energy confinement times often exceeding 200Â ms) that the attained density and temperature profiles would not have been possible in less optimized devices, since they would have had neoclassical transport losses exceeding the heating applied in W7-X. This provides proof that the reduction of neoclassical transport through magnetic field optimization is successful. W7-X plasmas generally show good impurity screening and high plasma purity, but there is evidence of longer impurity confinement times during turbulence-suppressed phases.EC/H2020/633053/EU/Implementation of activities described in the Roadmap to Fusion during Horizon 2020 through a Joint programme of the members of the EUROfusion consortium/ EUROfusio

Assessment of physiological traits of olive trees infected by Xylella fastidiosa subspecies
Trabajo presentado en la 9th Meeting of the IOBC-WPRS Working Group "Integrated Protection of Olive Crops", celebrado en Lisboa del 26 al 29 de octubre de 2021.The detection of the diseases caused by the plant pathogenic bacterium Xylella fastidiosa (Xf) is difficulted by the occurrence of asymptomatic infections, its long incubation period and non-specific and diagnostic symptoms. Early detection of infected plants based on the assessment of changes in physiological plant traits due to bacterial infection might be an important tool for pathogen detection, disease management and breeding for resistance to Xf in woody crops. Therefore, the objectives of this study were to evaluate the susceptibility to four Spanish Xf strains and the response to infection of three olive cultivars widely grown in Spain by measuring plant physiological traits with different leaf-level sensors and Xf-specific molecular diagnostic assays. Leaf measurements and petiole samplings were taken at the inoculation point, and at 5, 10, 15 and 20 cm above the inoculation points at 1, 3, 6, 12 and 18 months post-inoculation. Additionally, sampling of wood tissue was performed at 8 month post inoculation at the same plant sections of leaf sampling. Molecular diagnosis based on two qPCR tests was used to determine the presence and colonization level of the bacteria into the olive xylem tissues. The Dualex Scientific leaf clip sensor and two spectrometers (PolyPen RP400 and DLP NIRscan nano) covering the range of the electromagnetic spectrum from 340 and 1700 nm were used for leaf measurements to detect physiological changes. The Spanish strain XYL1961 from Xf subsp. pauca ST80 showed the highest colonization in the different olive cultivars as compared to strains from Xf subsp. multiplex from ST81 and ST6 from Spain and the Italian strain âDeDonnoâ from Xf subsp. pauca ST53. On the other hand, from a total of 70 vegetation indices calculated related with chlorophyll, carotenoid and flavonoids content and structural related indexes a set was selected to discriminate between olive plants infected by Xf from those non-inoculated even in the absence of visible disease symptoms.This work has received funding from 727987 XF-ACTORS (H2020-UE), E-RTA2017-00004-C06-02 (AEI-INIA Spain and FEDER), and the Spanish Olive Oil
