We investigate narrow quantum wires with strong Rashba spin-orbit coupling and electron-electron interactions. We show that virtual transitions between subbands lead to umklapp scattering which can open a partial gap in the spectrum even in the presence of time-reversal symmetry. Using the superconducting proximity effect to gap out the remaining modes, we show that the system can host zero-energy states at its edges, which are protected by time-reversal symmetry. We present the parameter regime in which these bound states will emerge. Similarly to Majorana bound states, they will produce a zero-bias peak in the differential conductance. In contrast to the Majorana fermions, however, their fourfold degeneracy leads to an 8π periodicity of the Josephson current due to tunneling of fractionalized excitations with charge e/2. [less ▲]

The 8th International Comparison of Absolute Gravimeters (ICAG2009) took place at the headquarters of the International Bureau of Weights and Measures (BIPM) from September to October 2009. It was the first ICAG organized as a key comparison in the framework of the CIPM Mutual Recognition Arrangement of the International Committee for Weights and Measures (CIPM MRA) (CIPM 1999). ICAG2009 was composed of a Key Comparison (KC) as defined by the CIPM MRA, organized by the Consultative Committee for Mass and Related Quantities (CCM) and designated as CCM.G-K1. Participating gravimeters and their operators came from national metrology institutes (NMIs) or their designated institutes (DIs) as defined by the CIPM MRA. A Pilot Study (PS) was run in parallel in order to include gravimeters and their operators from other institutes which, while not signatories of the CIPM MRA, nevertheless play important roles in international gravimetry measurements. The aim of the CIPM MRA is to have international acceptance of the measurement capabilities of the participating institutes in various fields of metrology. The results of CCM.G-K1 thus constitute an accurate and consistent gravity reference traceable to the SI (International System of Units), which can be used as the global basis for geodetic, geophysical and metrological observations of gravity. The measurements performed afterwards by the KC participants can be referred to the international metrological reference, i.e. they are SI-traceable. The ICAG2009 was complemented by a number of associated measurements: the Relative Gravity Campaign (RGC2009), high-precision levelling and an accurate gravity survey in support of the BIPM watt balance project. The major measurements took place at the BIPM between July and October 2009. Altogether 24 institutes with 22 absolute gravimeters (one of the 22 AGs was ultimately withdrawn) and nine relative gravimeters participated in the ICAG/RGC campaign. This paper is focused on the absolute gravity campaign. We review the history of the ICAGs and present the organization, data processing and the final results of the ICAG2009. After almost thirty years of hosting eight successive ICAGs, the CIPM decided to transfer the responsibility for piloting the future ICAGs to NMIs, although maintaining a supervisory role through its Consultative Committee for Mass and Related Quantities.

90Sr, 210 Pb, 210Po and Ra isotopes were determined in macroalgae Ceramium rubrum, Cystoseira crinita, Ulva rigida, Cladophora vagabunda, Enteromor- pha intestinalis and in mussels Mytilus galloprovincialis collected from the Bulgarian Black Sea coast. Radio- chemical separation was made by a fast and reproducible procedure based on a calcium phosphate precipitation technique. The obtained results for macroalgae vary in the interval 0.23–0.85 Bq kg-1 for 90Sr, 2.2–10.6 Bq kg-1 for 210Pb, 1.2–9.7 Bq kg-1 for 210Po and 1.9–13.2 Bq kg-1 for Ra isotopes. Data obtained for mussels demonstrate similar abilities in the accumulation of 90Sr, 210Pb and Ra isotopes. [less ▲]

We propose a flow cytometry concept that combines a spatial optical modulation scheme and deep learning for lensless cell imaging. Inspired by auto-encoder techniques, an artificial neural network mimics the optical transfer function of a particular microscope and camera for certain types of cells once trained and reconstructs microscope images from simple waveforms that are generated by cells in microfluidic flow. This eventually enables the label-free detection of cells at high throughput while simultaneously providing their corresponding brightfield images. The present work focuses on the computational proof of concept of this method by mimicking the waveforms. Our suggested approach would require a minimum set of optical components such as a collimated light source, a slit mask, and a light sensor and could be easily integrated into a ruggedized lab-on-chip device. The method is benchmarked with a well-investigated dataset of red blood cell images. [less ▲]

Pour tenter de contribuer humblement au propos de ce colloque intitulé : « Quand les femmes filment : le documentaire dans la péninsule ibérique et dans le continent latino-américain », nous nous proposons d’analyser A Falta que nos move (Le manque qui nous meut) de Christiane Jatahy. Depuis 2002, les créations hybrides de cette auteure, metteure en scène et cinéaste carioca se situent sur une « ligne ténue entre réalité et fiction »1. A Falta que nos move en témoigne. En 2005, A Falta que nos move est tout d’abord une création scénique qui est, durant trois ans, présentée dans de nombreux festivals brésiliens et européens. Ensuite, en 2008, A Falta que nos move devient un long métrage documenté tourné en treize heures au sein duquel l’entre-deux théâtre / cinéma génère une tension radicale entre la réalité et la fiction. Cette expérience filmique se situe à la frontière avec la télé-réalité : cinq amis acteurs trentenaires brésiliens se réunissent la veille de Noël. Chacun a grandi sous la dictature militaire, façonné par les produits culturels américains. Ils attendent un invité et s’adressent continuellement au public. Comment Christiane Jatahy procède-t-elle ? Quelle est sa manière de travailler avec les acteurs pour en arriver à brouiller les rapports entre les personnes physiques et les personnages fictifs ? Comment un vrai parti pris esthétique et dramaturgique apparaît-il ? Comment le cinéma influence-t-il le théâtre et vice versa ? C’est précisément à toutes ces questions que nous entendons répondre.

A Floresta que anda (La Forêt qui marche) est le titre de la création proposée, en 2016, par Christiane Jatahy au Cent-Quatre à Paris, librement inspirée par Macbeth de William Shakespeare. Il s’agit d’une installation ou plus précisément de la construction d’un espace au sein duquel se déplacent les « spect-acteurs ». Dans cette " salle d’exposition " créée pour l’occasion, il existe une structure d’écrans mobiles reliés, chacun, à un vidéoprojecteur qui diffuse une vidéo différente afin de faire entendre la voix des exclus. Tout commence par un documentaire et une vidéo d’installation. Il s’agit en somme d’un mélange de théâtre, de performance et d’exposition d’art vidéo. Dans ce cadre spécifique, les sorcières, représentation du surnaturel dans Macbeth , sont incarnées par Christiane Jatahy lorsqu’elle s’adresse aux spectateurs et délivre cette œuvre au public. Lady Macbeth, quant à elle, symbolise le pouvoir assassin, le désir d’enrichissement et « la luxure inextinguible du pouvoir qui s’autoalimente » . Quant à Macbeth, il devient un personnage contemporain qu’il y a lieu de chercher dans le réel et non pas uniquement dans la fiction. Macbeth représente le système social, économique et politique dans lequel nous vivons aujourd’hui et qui est tout aussi pervers que le personnage en lui-même. Comment Christiane Jatahy procède-t-elle pour adapter Macbeth ? Quelle est sa manière de travailler avec les acteurs pour en arriver à brouiller les rapports entre les personnes physiques et les personnages fictifs ? Comment un vrai parti pris esthétique et dramaturgique apparaît-il ? Comment le cinéma influence-t-il le théâtre et vice versa ? Comment apparaît cette « ligne ténue entre réalité et fiction » , laquelle étonne et déroute les « spect-acteurs » ? C’est précisément à toutes ces questions auxquelles nous répondons dans cet article. [less ▲]
