To detect directional couplings from time series various measures based on distances in reconstructed state spaces were introduced. These measures can, however, be biased by asymmetries in the dynamics' structure, noise color, or noise level, which are ubiquitous in experimental signals. Using theoretical reasoning and results from model systems we identify the various sources of bias and show that most of them can be eliminated by an appropriate normalization. We furthermore diminish the remaining biases by introducing a measure based on ranks of distances. This rank-based measure outperforms existing distance-based measures concerning both sensitivity and specificity for directional couplings. Therefore, our findings are relevant for a reliable detection of directional couplings from experimental signals.

PURPOSE: To explore detainees and staff's attitudes towards tobacco use, in order to assist prison administrators to develop an ethically acceptable tobacco control policy based on stakeholders' opinion. DESIGN: Qualitative study based on in-depth semi-structured interviews with 31 prisoners and 27 staff prior (T1) and after the implementation (T2) of a new smoke-free regulation (2009) in a Swiss male post-trial prison consisting of 120 detainees and 120 employees. RESULTS: At T1, smoking was allowed in common indoor rooms and most working places. Both groups of participants expressed the need for a more uniform and stricter regulation, with general opposition towards a total smoking ban. Expressed fears and difficulties regarding a stricter regulation were increased stress on detainees and strain on staff, violence, riots, loss of control on detainees, and changes in social life. At T2, participants expressed predominantly satisfaction. They reported reduction in their own tobacco use and a better protection against second-hand smoke. However, enforcement was incomplete. The debate was felt as being concentrated on regulation only, leaving aside the subject of tobacco reduction or cessation support. CONCLUSION: Besides an appropriate smoke-free regulation, further developments are necessary in order to have a comprehensive tobacco control policy in prisons.

We propose an edge detector based on the selection of wellcontrasted pieces of level lines, following the proposal ofDesolneux-Moisan-Morel (DMM) [1]. The DMM edge detectorhas the problem of over-representation, that is, everyedge is detected several times in slightly different positions.In this paper we propose two modifications of the originalDMM edge detector in order to solve this problem. The firstmodification is a post-processing of the output using a generalmethod to select the best representative of a bundle of curves.The second modification is the use of Canny’s edge detectorinstead of the norm of the gradient to build the statistics. Thetwo modifications are independent and can be applied separately.Elementary reasoning and some experiments showthat the best results are obtained when both modifications areapplied together.

A new radiolarian order - Archaeospicularia - is proposed for some Lower Paleozoic radiolarians previously considered to belong to Spumellaria and to Collodaria. It is characterized by a globular shell made of several spicules which can be free, interlocked, or fused to formed a latticed wall. The present paper gives the definition of this order and proposes a first classification. It is supposed that the Archaeospicularia represents the oldest radiolarian group and that in the Lower Paleozoic it gave rise to the orders Entactinaria, Albaillellaria, and probably Spumellaria by the reduction of the number of initial spicules. The origin of this order and its relationships with other groups of organisms with siliceous skeletons are also briefly discussed.

Head and neck squamous cell carcinomas are frequently diagnosed at an advanced stage. Their treatment remains controversial, and has to be multidisciplinary. External beam radiotherapy is a recognized treatment option after radical curative surgery in order to improve local control. Different adjuvant treatment options have been studied in order to improve the outcome of these patients. We review in this paper the different prognostic factors indicating an adjuvant treatment and the interest of treatment intensification in bad prognostic patients.
