Justice and Home Affairs databases and a Smart Borders System at EU external borders. An evaluation of current and forthcoming proposals. CEPS Paper in Liberty and Security No. 52/December 2012

This study examines current and forthcoming measures related to the exchange of data and information in EU Justice and Home Affairs policies, with a focus on the ‘smart borders’ initiative. It argues that there is no reversibility in the growing reliance on such schemes and asks whether current and forthcoming proposals are necessary and original. It outlines the main challenges raised by the proposals, including issues related to the right to data protection, but also to privacy and non-discrimination.

The EU's External Action towards the Middle East: Resolution required. CEPS Commentary, 7 January 2012

Among the many foreign policy challenges the EU will have to address this year, such as cultivating workable ties with Ukraine, Russia and other neighbours in the east, reviving the transatlantic partnership in trade, rebalancing alliances with Asian countries, and pooling and sharing defence capabilities, the number one challenge that will take up most of the Foreign Affairs Council’s time is the Middle East. After months of half-baked unilateral attempts at resolving the foreign policy challenges posed by this troubled region, the moment has now come for the EU to take bold and concrete action, argues CEPS Senior Fellow Steven Blockmans in this new Commentary.

Response of the lower St. Lawrence Estuary to external forcing in winter

Mostly because of a lack of observations, fundamental aspects of the St. Lawrence Estuary's wintertime response to forcing remain poorly understood. The results of a field campaign over the winter of 2002/03 in the estuary are presented. The response of the system to tidal forcing is assessed through the use of harmonic analyses of temperature, salinity, sea level, and current observations. The analyses confirm previous evidence for the presence of semidiurnal internal tides, albeit at greater depths than previously observed for ice-free months. The low-frequency tidal streams were found to be mostly baroclinic in character and to produce an important neap tide intensification of the estuarine circulation. Despite stronger atmospheric momentum forcing in winter, the response is found to be less coherent with the winds than seen in previous studies of ice-free months. The tidal residuals show the cold intermediate layer in the estuary is renewed rapidly ( 14 days) in late March by the advection of a wedge of near-freezing waters from the Gulf of St. Lawrence. In situ processes appeared to play a lesser role in the renewal of this layer. In particular, significant wintertime deepening of the estuarine surface mixed layer was prevented by surface stability, which remained high throughout the winter. The observations also suggest that the bottom circulation was intensified during winter, with the intrusion in the deep layer of relatively warm Atlantic waters, such that the 3 C isotherm rose from below 150 m to near 60 m.

Converting the nanodomains of a diblock-copolymer thin film from spheres to cylinders with an external electric field

We investigate the ability of an applied electric field to convert the morphology of a diblock-copolymer thin film from a monolayer of spherical domains embedded in the matrix to cylindrical domains that penetrate through the matrix. As expected, the applied field increases the relative stability of cylindrical domains, while simultaneously reducing the energy barrier that impedes the transition to cylinders. The effectiveness of the field is enhanced by a large dielectric contrast between the two block-copolymer components, particularly when the low-dielectric contrast component forms the matrix. Furthermore, the energy barrier is minimized by selecting sphere-forming diblock copolymers that are as compositionally symmetric as possible. Our calculations, which are the most quantitatively reliable to date, are performed using a numerically precise spectral algorithm based on self-consistent-field theory supplemented with an exact treatment for linear dielectric materials.
