Research review (peer-reviewed)abstract
- This paper reports the highlights of the RFX-mod fusion science programme since the last 2010 IAEA Fusion Energy Conference. The RFX-mod fusion science programme focused on two main goals: exploring the fusion potential of the reversed field pinch (RFP) magnetic configuration and contributing to the solution of key science and technology problems in the roadmap to ITER. Active control of several plasma parameters has been a key tool in this endeavour. New upgrades on the system for active control of magnetohydrodynamic (MHD) stability are underway and will be presented in this paper. Unique among the existing fusion devices, RFX-mod has been operated both as an RFP and as a tokamak. The latter operation has allowed the exploration of edge safety factor q edge < 2 with active control of MHD stability and studies concerning basic energy and flow transport mechanisms. Strong interaction has continued with the stellarator community in particular on the physics of helical states and on three-dimensional codes.

To what extent can dynamical models describe statistical features of turbulent flows?

- Statistical features of "bursty" behaviour in charged and neutral fluid turbulence are compared to statistics of intermittent events in a GOY shell model, and avalanches in different models of Self-Organized Criticality (SOC). It is found that inter-burst times show a power law distribution for turbulent samples and for the shell model, a property which is shared only in a particular case of the running sandpile model. The breakdown of self-similarity generated by isolated events observed in the turbulent samples is well reproduced by the shell model, while it is absent in all SOC models considered. On this base, we conclude that SOC models are not adequate to mimic fluid turbulence, while the GOY shell model constitutes a better candidate to describe the gross features of turbulence.

Evaluation of a novel antiplatelet agent for secondary prevention in patients with a history of atherosclerotic disease: design and rationale for the Thrombin-Receptor Antagonist in Secondary Prevention of Atherothrombotic Ischemic Events (TRA 2 degrees P)-TIMI 50 trial

- BACKGROUND: Thrombin potently activates platelets via interaction with the protease-activated receptor 1. SCH 530348 is a novel antiplatelet agent that selectively inhibits the cellular actions of thrombin via antagonism of the protease-activated receptor 1. Because SCH 530348 does not interfere with other pathways for hemostasis, it is possible that SCH 530348 reduces thrombosis with less increase in bleeding than do other potent antiplatelet agents. STUDY DESIGN: TRA 2 degrees P-TIMI 50 is a phase III, randomized, double-blind, placebo-controlled, multinational clinical trial designed to evaluate the efficacy and safety of SCH 530348 during long-term treatment of patients with established atherosclerotic disease receiving standard therapy (up to 27,000). Eligible patients with a history of myocardial infarction, ischemic stroke, or peripheral arterial disease are randomized 1:1 to SCH 530348 2.5 mg daily or matched placebo until the end of study. Randomization is stratified by the qualifying disease and planned use of a thienopyridine. The primary end point is the composite of cardiovascular death, myocardial infarction, stroke, or urgent coronary revascularization. The major secondary end point is the composite of cardiovascular death, myocardial infarction, or stroke. The evaluation of long-term safety includes bleeding defined by the GUSTO and TIMI criteria. Recruitment began in September 2007. The trial will continue until 2,279 primary end points and 1,400 secondary end points are recorded with expected completion in 36 to 44 months from first enrollment. CONCLUSIONS: TRA 2 degrees P-TIMI 50 is evaluating whether a new approach to platelet inhibition via interruption of thrombin-mediated platelet activation reduces major cardiovascular events with a favorable safety profile in patients with established atherosclerosis.

Intermittency and turbulence in a magnetically confined fusion plasma
- 2000
-
In: Physical Review E. Statistical, Nonlinear, and Soft Matter Physics. - : American Physical Society (APS). - 1539-3755 .- 1550-2376. ; 62:1, s. R49-R52

Journal article (peer-reviewed)abstract
- The intermittency of the magnetic turbulence in reversed field pinch plasmas was measured. The probability distribution functions of magnetic field differences were not scale invariant because the wings of these functions were more important as the scales become smaller. This phenomena was identified as a classical signature of intermittency. The scaling laws also appeared very close to the external wall of the confinement device.

Publication strategy for junior researchers: Quantity vs. quality, the first authorship and the optimal number of authors
- 2012

Conference paper (peer-reviewed)abstract
- A good publication record is one of the most important prerequisites of a successful academic career in IS. Despite the weight hiring and promotion committees place on it, the definition of a "good publication record" especially for junior researchers remains unclear. Indeed, is it better to have one A-publication or three B-publications? Does being the third author on an A-publication have a bigger weight than being the first author on a B-publication? Should one strive to publish with as few coauthors as possible to demonstrate that one is capable of independent work? Facing these ambiguities, young researchers are increasingly asking themselves about the choices they make with regard to their publication strategy. Equally, academic mentors have a strong interest in correctly setting incentives of their young protégés. If unaddressed, uncertainty regarding these issues is bound to interfere with the quality of the IS research and scholars' job and life satisfaction. This panel proposal aims to offer a forum for discussion and clarification on these problematic issues. Specifically, the following topics will be raised: quantity vs. quality, value of the first authorship and optimal number of authors.

Magnetic turbulence in space plasmas : Scale-dependent effects of anisotropy
- 2009
-
In: Journal of Geophysical Research. - 0148-0227 .- 2156-2202. ; 114, s. A02102-
-
Journal article (peer-reviewed)abstract
- The presence of a background magnetic field induces anisotropy in magnetic turbulence. Understanding properties of anisotropy is important to characterize turbulence power spectrum. This paper presents a case study of anisotropy by using a minimum variance analysis, in three different regions of the heliosphere, namely in the solar wind, and in the Earth's foreshock and magnetosheath behind a quasiparallel bow shock. A strong anisotropy is found in all cases, with very interesting cross-scale effects at the ion cyclotron frequency. In particular, (1) the eigenvalues of the variance matrix have a strong intermittent behavior, with very high localized fluctuations below the ion cyclotron scale. As a consequence the probability distribution functions are almost Gaussian5 above the ion cyclotron scale and become power laws at smaller scales; (2) the minimum variance direction is almost parallel to the background magnetic field at scales larger than the ion cyclotron scale in the solar wind and in the foreshock, while their probability density functions become broader at smaller scales. In the magnetosheath the minimum variance direction exhibits a tendency to become nearly perpendicular to the large-scale magnetic field below the ion cyclotron scale.
