Laval University is the oldest centre of education in Canada , and was the first institution in North America to offer higher education in French. Its main campus is located on the outskirts of the historic city in Quebec City, the capital of the Province of Quebec. The university is ranked among the top ten Canadian universities in terms of research funding. Wikipedia.

Liquid crystal modulator optical devices and more specifically shutters and smart windows are presented. The liquid crystal modulator devices are characterized by a reduced polymer content which is eliminated from the material composition of the liquid crystal layer and characterized by non-uniform electrode structures in the liquid crystal structure configured to generate spatially non-uniform electric fields and therefore non-uniform molecular reorientation of liquid crystal molecules. This arrangement advantageously makes light scattering electrically controllable.

A method for synthesizing a protein of interest within a plant or a portion of a plant is provided. The method involves treating the plant to increase secondary leaf biomass production, followed by introducing one or more than one nucleic acid sequence encoding a protein of interest operatively linked with a regulatory region that is active in the plant, into the plant. The plant is then maintained under conditions that permit the nucleic acid sequence encoding the protein of interest to be expressed in the plant or the portion of the plant. Optionally, the plant or portion of the plant may be harvested and the protein of interest extracted.

The present invention relates to the use of leukotriene B_(4 )to enhance the response of Toll-like receptor (TLR), RIG-I-like receptor (RLR), and NOD-like receptor (NLR) when stimulated simultaneously with respective proper ligands. The use in combination of LTB_(4 )with those ligands is useful to potentiate immune response for the treatment of autoimmune diseases, immunosuppressive diseases, as well as immunological disorders.

A parallel mechanism comprises legs with kinematically redundant actuation for a parallel mechanism. Each of these legs comprises a first sub-leg and a second sub-leg, each said sub-leg comprising a proximal end and a distal end. A link has a proximal end and a distal end. A joint with a rotational degree of freedom (DOF) is between and common to the distal ends of each of the first sub-leg and the second sub-leg, and the proximal end of the link. A joint provides at least two rotational DOFs at the distal end of the link and is adapted to connect the distal end of the link to one end of the parallel mechanism. Joints in the first sub-leg and the second sub-leg to provide DOFs to the sub-legs and to connect the proximal ends of the sub-legs to the other end of the parallel mechanism. A degree of actuation (DOA) is provided for each of the first sub-leg and the second sub-leg to control movement of the link. A method for controlling movement of the parallel mechanism is also provided.

A method for preparing polymers by direct heteroarylation or arylation polycondensation is described herein. The method includes preparing a reaction mixture including at least a monomer to be polymerized, a catalyst and a ligand; heating the reaction mixture; and, optionally, end-capping the reaction mixture.

A movement device is moved along an X axis and a Y axis by providing a sensor configured to measure angle of rotation of at least one of a first and a second kinematic link about a respective axis of rotation. A force is imparted on the first and second kinematic links such that an angular displacement of the first and second kinematic links about the respective axis of rotation is achieved. The angular displacement of the first and second kinematic links about the respective axis of rotation is determined. The movement device is moved along the X axis and/or the Y axis in response to the determination of the angle of rotation of the first and second kinematic links about the respective axis of rotation until first and second kinematic links are vertical.

An extended-reach assist device for an assembly task includes a base mechanism and a compliant end-effector. The articulated base mechanism provides one or more passive degrees of freedom. The end-effector is connected to the base mechanism, and has one or more active or passive degrees of freedom collectively configured to react to contact forces with the assist device when completing the dexterous assembly task. A weight of the end-effector is supported by the base mechanism. The end-effector may be optionally configured as a passive device configured to produce a remote center of compliance or as a robot mechanism. A mechanism may actively or passively augment a force applied by the operator. A sensor may detect a signature indicative of successful task completion, e.g., an acoustic, visual, or audio sensor.

The present invention relates to an artificial light system for modulating circadian rhythms, increasing vigilance and influencing light-associated psychological conditions such as seasonal affective disorder. The system of the invention comprises a source of a green and/or red light and a source of blue light both light sources being controlled by a computer to provide predetermined light conditions. More specifically, the computer is programmed to provide pulses of blue light and continuous or pulsed red light, to enhance the efficacy of blue light, reduce blue-light hazard and avoid stroboscopic effect.
