— Laser induced convection flows is a new and promising method to achieve better manipulation of mesoscale objects (above 1 µm and below 500 µm) in a liquid medium. The temperature gradient created by laser absorption generates natural and thermocapillary (or Marangoni) convection flows. These flows are used to perform the manipulation itself. In this(More)
We propose to study Deep Virtual Compton Scattering (DVCS) using the CEBAF 6 GeV polarized electron beam and the CLAS detector at Jefferson Lab. The main focus of the experiment will be measurement of the beam spin asymmetry in the reaction ep → epγ. This asymmetry is directly proportional to the imaginary part of the DVCS amplitude and gives access to a(More)
OBJECTIVE In this study, we explored the time course of haptic stiffness discrimination learning and how it was affected by two experimental factors, the addition of visual information and/or knowledge of results (KR) during training. BACKGROUND Stiffness perception may integrate both haptic and visual modalities. However, in many tasks, the visual field(More)
The beam-spin asymmetries in the hard exclusive electroproduction of photons on the proton (e p-->epgamma) were measured over a wide kinematic range and with high statistical accuracy. These asymmetries result from the interference of the Bethe-Heitler process and of deeply virtual Compton scattering. Over the whole kinematic range (x(B) from 0.11 to 0.58,(More)
The photoproduction of the ! meson has been studied at GRAAL from threshold up to a photon energy of 1.5 GeV. The differential cross sections and beam asymmetries have been measured precisely at all angles. The total cross section is also obtained. Systematic enhancements of the differential cross section at large angles and nonzero beam asymmetries at(More)
We have measured the 3He(e,e'pp)n reaction at 2.2 GeV over a wide kinematic range. The kinetic energy distribution for "fast" nucleons (p>250 MeV/c) peaks where two nucleons each have 20% or less, and the third nucleon has most of the transferred energy. These fast pp and pn pairs are back to back with little momentum along the three-momentum transfer,(More)
The use of touch-based interaction now dominates the market as it enables a more natural form of interaction with our devices, but is largely limited to flat and rigid surfaces. The increasing availability of flexible interactive technologies offers us the opportunity to design devices that adapt to their context of use and opens up new avenues for the(More)
