Abstract: Optical system comprising two optical fibres which are configured to define between them a Fabry-Perot cavity, and a connecting element bonded to each of the two optical fibres, the connecting element defining a through-passage, at least one of the two optical fibres comprising an end portion arranged in the through-passage and bonded to the connecting element, the two optical fibres extending along an axis and being separated from one another by a distance Le parallel to the axis, one of the optical fibres being bonded to the connecting element at a first bonding zone, and the other optical fibre being bonded to the connecting element at a second bonding zone separated from the first bonding zone by distance parallel to the axis.

Abstract: An animal feed dispenser includes a control module and a feed dispensing module. The control module includes a detection member and an electronic control card. The detection member is suitable for generating a detection signal when the feed dispenser is located close to an enclosure containing animals. The feed dispensing module includes a feed dispensing orifice and an actuator. The electronic control card is configured to receive the detection signal and, as a function of the detection signal, to transmit an activation signal to the actuator and the actuator is configured to trigger a flow of feed through the dispensing orifice when the activation signal is received.

Abstract: The invention relates to a method for characterising bone, the method comprising the steps of receiving (102) ultrasonic wave echo signals transmitted into a body, determining (104) a speed of sound in the body's non-bone biological tissue, locating (106) a first demarcation curve between non-bone biological tissue and bone in an image of the body constructed during said determining step, and determining (108) a speed of sound in bone. The steps of determining speed include constructing images from the signals, and a metric calculation indicative of a focus quality in the constructed images.

Abstract: The system has: a set of at least two electric current generators, at least one capacitor and activation/deactivation devices for the electric current generators; the electric current generator being connected in parallel with one another and the capacitor being connected in series with the electric current generators, the activation/deactivation devices controlling the generators by a digital stream allowing control of the intensity of the electric current entering the capacitor and generating a trapezoidal voltage signal at the terminals of the capacitor, the analog signal being reconstructed through interpolation of the trapezoidal signal.

Abstract: The invention relates to polypeptides containing a cytoplasmic domain ending with a MAST-2 binding domain, from 11 to 13 residues, the first two residues of which are S and W, and the last four residues of which are Q, T, R and L, said polypeptides presenting a high affinity for the PDZ domain of the human MAST2 protein. The invention also relates to polynucleotides, vectors, lentiviral particles, cells as well as compositions comprising the same. The invention is also directed to the use of said polypeptides, polynucleotides, vectors, lentiviral particles, cells and compositions in the treatment and/or prevention of a disease, disorder or condition, which alters the Central Nervous System (CNS) and/or the Peripheral Nervous System (PNS). The invention also concerns molecular signatures of cellular genes to determine the neurosurvival and/or neuroprotection activity of a molecule.

Abstract: Method for the preparation of a composite electrode and accumulator or battery including at least one composite electrode, the method includes a step of pouring a medium including at least one ionic liquid, a lithium, sodium or magnesium salt with at least one inorganic molecular precursor or a polymerizable monomer, the medium being in excess, and an in situ polycondensation or polymerization step.

Abstract: The present invention relates to polymeric binders of formula: [(—CH2CF2—)x?(—CF2CF2—)y?[—CH2CH(R)—]z?]m wherein: x?+y?+z?=1, only one x?, y? or z? could be simultaneously equal to zero; R is an alkyl radical CnH2n+1— with 0?n?8, 10?m?106.

Abstract: A method for the assessment of pulmonary ventilation and lung perfusion through Magnetic Resonance Imaging (MRI), comprising the steps of: positioning a human subject in an MRI apparatus, delivering a hyperpolarized noble gas to the subject by inhalation, followed by a breath-hold period, during which a bolus of a contrast agent for MRI is injected intravenously, acquiring, during the breath-hold period, at least one MR image of the lungs prior to the bolus intravenous injection and at least one MR image thereafter.

Abstract: The invention concerns 2,N.sup.6 -disubstituted and 2,N.sup.6 -trisubstituted adenosine nucleosides in which the sugar component is substituted at position 3' or position 5' by a phosphite or phosphoramidite group of the formula: ##STR1## R.sub.1 representing a lower alkyl or --(CH.sub.2).sub.n --CN with n being an integer between 1 and 4, and X representing a halogen or an amine group. These nucleosides make it possible to prepare sequences of nucleotides usable, in particular, as probes in the field of analyses and biological extractions.
