Migration dynamics of incoming eels in Belgium via Lixhe in the Meuse River were investigated using two fish passes with different configurations— net traps and automatic detection stations—as tools to distinguish resident and migrating eels. From April to September 2013, 435 eels (P50 length, 403 mm; range, 196–836 mm) were caught (daily maxima catch, 90 eels per day), 90% between 13 June and 1 August (50 days) and P50 on 19 July. Eels migrated mostly at 19–26 °C (P50, 24.4 °C), river discharge 65–314m3 s 1 (P50, 84m3 s 1), during the dark at 00:00–05:00 h and during both the waxing and waning phases of moonlight. From 396 eels tagged and released 0.3 km downstream of the Lixhe dam, 6.8% of them were recaptured, and 37.4% were detected. Migration flux was estimated at 7184 eels (0.863 t) using the markrecapture method and decreased to 1156 eels (0.139 t) using automatic transponder detection. Most eels probably migrated through a sluice located downstream of Lixhe to reach the upper Meuse via the Albert Canal. Eels moved almost independently to the configuration of the fish passes and their location, but most eels displayed fidelity to the fish pass where they were captured. Migrant eels showed a wide range of size and life stages, with a higher proportion of eels (80%) belonging to the yellow eel stage. A lower proportion of eels (6%) had a larger size and presented an advanced continental silvering process corresponding to the migrating stage before their transatlantic migration.

This paper consists in the description and application of a new method named Wavelet-Induced Mode Extraction (WIME) in the context of time-frequency analysis. WIME aims to extract the oscillating components that build amplitude modulated-frequency modulated signals. The essence of this technique relies on the successive extractions of the dominant ridges of wavelet-based timefrequency representations of the signal under consideration. Our tests on simulated examples indicate strong decomposition and reconstruction skills, trouble-free handling of crossing trajectories in the time-frequency plane, sharp performances in frequency detection in the case of mode-mixing problems and a natural tolerance to noise. These results are compared with those obtained with the Empirical Mode Decomposition. We also show that WIME still gives meaningful results with real-life data, namely the Oceanic Niño Index.

Background: In the PREVention and Acute treatment of chronic cluster headache (PREVA) study, attack frequency reductions from baseline were significantly more pronounced with non-invasive vagus nerve stimulation plus standard of care (nVNS + SoC) than with SoC alone. Given the intensely painful and frequent nature of chronic cluster headache attacks, additional patient-centric outcomes, including the time to and level of therapeutic response, were evaluated in a post hoc analysis of the PREVA study. Findings: After a 2-week baseline phase, 97 patients with chronic cluster headache entered a 4-week randomised phase to receive nVNS + SoC (n = 48) or SoC alone (n = 49). All 92 patients who continued into a 4-week extension phase received nVNS + SoC. Compared with SoC alone, nVNS + SoC led to a significantly lower mean weekly attack frequency by week 2 of the randomised phase; the attack frequency remained significantly lower in the nVNS + SoC group through week 3 of the extension phase (P < 0.02). Attack frequencies in the nVNS + SoC group were significantly lower at all study time points than they were at baseline (P < 0.05). Response rates were significantly greater with nVNS + SoC than with SoC alone when response was defined as attack frequency reductions of ≥25%, ≥50%, and ≥75% from baseline (≥25% and ≥50%, P < 0.001; ≥75%, P = 0.009). The 100% response rate was 8% with nVNS + SoC and 0% with SoC alone. Conclusions: Prophylactic nVNS led to rapid, significant, and sustained reductions in chronic cluster headache attack frequency within 2 weeks after its addition to SoC and was associated with significantly higher ≥25%, ≥50%, and ≥75% response rates than SoC alone. The rapid decrease in weekly attack frequency justifies a 4-week trial period to identify responders to nVNS, with a high degree of confidence, among patients with chronic cluster headache. [less ▲]

This paper argues that the analysis of legal mobilization needs to give more attention to the state and its relationship with social movements in order to examine how the state either sustains social movements' demands or is a field of contention for those demands. Focusing on how disability bureaucrats and activists mobilize antidiscrimination law in Sweden, this article shows that two main factors shape legal mobilization within the bureaucracy and alter the state's ability to become a legal mobilization actor: (1) the institutional relationships between social movement organizations and government agencies; and (2) the profiles and careers of bureaucrats and activists. It concludes by suggesting several lines for further research on law and social movements in nonpluralist countries. [less ▲]

This paper describes the degree of obligation created by a FRAND commitment on the holders of a Standard Essential Patent (“SEP”) from an EU competition law perspective. It shows that the EU courts case-law does not seem supportive of the reading of FRAND as a distributional, pricing commitment. Instead, it views FRAND as a soft commitment device, designed to promote cooperation and exchange amongst independent firms. This is apparent in the Huawei v ZTE judgment, which conveys an invitation on both SEP holders and unlicensed implementers to follow basic procedural requirements in licensing talks. In addition, the paper contributes to the debate on the legal applicability of Article 102 TFEU to SEP holders other than practicing entities. Last, the paper discusses if Standard Setting Organizations (“SSOs”) ex ante specifications of FRAND terms can constrain the conduct of SEP holders under EU competition law. [less ▲]

A novel theory of harm is crystallising in European Union (“EU”) merger control. Under this theory, the EU Commission (“Commission”) can intervene in mergers that it considers generally reduce innovation incentives in an industry as a whole. This theory of harm can be referred to as the Significant Impediment to Industry Innovation (“SIII”) theory. This policy paper first attempts to describe the content and extent of the SIII theory (I). Second, it shows that the SIII theory marks a departure from established EU merger control practice (II). Third, it discusses the economic foundations of the SIII theory (III). Finally, it puts forward best practices for the assessment of mergers in R&D intensive industries (IV). With this, the present paper hopes to assist the development of sound merger control policy in innovative markets, and undermine crude conjectures on the relationship between market structure, patent statistics and industry innovation theory.

Background: Lack of habituation of visual evoked potentials (VEP) is a common finding in migraine patients between attacks. Previous studies have suggested an electrophysiological familial aggregation pattern associated with migraine. The aim of this study was to evaluate the influence of a positive familial history of migraine on VEP amplitude and habituation. Methods: We recorded six blocks of 100 VEP during continuous pattern-reversal stimulation in 30 patients with migraine between attacks (MO) and in 30 healthy volunteers, of whom 15 had a first-degree relative suffering from migraine (HVm) and 15 had not (HV). Results: Both MO and HVm had a significant deficit of VEP habituation and similarly reduced N1-P1 first block amplitudes, compared to HV (habituation slope: MO ¼ 0.033, HVm ¼ 0.021, HV ¼ 0.025, HV vs. MO p ¼ 0.002, HV vs. HVm p ¼ 0.036; mean N1-P1 amplitude in the first block: MO ¼ 9.08 mV, HVm ¼ 9.29 mV, HV ¼ 12.19 mV. HV vs. MO p ¼ 0.041, HV vs. HVm p ¼ 0.076). The first block N1-P1 amplitude was negatively correlated with the habituation slope for both MO (r ¼ .44, p ¼ 0.015) and HVm (r ¼ .56, p ¼ 0.031) while no significant correlation was found in HV (r ¼ .17, p ¼ 0.53). There were no differences in VEP latencies between the groups. Conclusions: Our study suggests that lack of habituation of visual evoked potentials is probably a genetically determined endophenotypic trait that is associated with both migraine and migraine susceptibility. We hypothesize that genetic diversity of populations could account for some of the discrepancies between electrophysiological studies performed in migraine and for interindividual variations among the subgroups.

Pauly (1990) argues that an explanation for the low long-term care (LTC) insurance demand could be intra-family moral hazard: parents might refuse to buy insurance since it reduces children’s incentives to provide care. This paper raises and explores the idea that the extent of intra-family moral hazard and non-purchase of LTC insurance might differ when insurance benefits are fixed and when they are proportional to LTC expenditures. It shows that fixed benefits limit and might even eliminate intra-family moral hazard, while the effect of proportional benefits is at best ambiguous. Consequently, non-purchase of insurance is less likely with fixed benefits. [less ▲]

Adhesion is an important phenomenon in the context of MEMS for which the surface forces become dominant in comparison with the body forces. Because the magnitudes of the adhesive forces strongly depend on the surface interaction distances, which in turn evolve with the roughness of the contacting surfaces, the adhesive forces cannot be determined in a deterministic way. To quantify the uncertainties on the structural stiction behavior of a MEMS, this work proposes a “stochastic multi-scale methodology”. The key ingredient of the method is the evaluation of the random meso-scale apparent contact forces, which homogenize the effect of the nano-scale roughness and are integrated into a numerical model of the studied structure as a random contact law. To obtain the probabilistic behavior at the structural MEMS scale, a direct method needs to evaluate explicitly the meso-scale apparent contact forces in a concurrent way with the stochastic multi-scale approach. To reduce the computational cost, a stochastic model is constructed to generate the random meso-scale apparent contact forces. To this end, the apparent contact forces are parameterized by a vector of parameters before applying a polynomial chaos expansion in order to construct a mathematical model representing the probability of the random parameters vector. The problem of micro-beam stiction is then studied in a probabilistic way. [less ▲]

L’article propose une réflexion critique et clinique sur la notion de « personnalité antisociale », largement usitée dans le domaine de la nosographie des troubles mentaux et des pratiques « psy- » au sein du système de justice pénale. Notre réflexion débutera par une généalogie du vocable dans différentes versions de la classification psychiatrique, depuis les années cinquante jusqu’aujourd’hui, et plus particulièrement celle faisant autorité du Manuel statistique et diagnostique des troubles mentaux (DSM). L’absence de raisonnement sociologique dans l’usage d’une notion impliquant pourtant la référence au « social » sera discutée ainsi que ses évolutions historiques. Ensuite, la démonstration de l’antithèse que cette notion constitue pour une perspective psychopathologique digne de ce nom – dynamique, compréhensive et phénoménologique – sera développée en six arguments majeurs et plurivoques, tantôt empiriques et cliniques, tantôt théoriques.
