In the brain, high cognitive functions are encoded by coherent network oscillations. Key players are inhibitory interneurons that, by releasing GABA into principal cells, pace targeted cells. Among these, oriens-lacunosum moleculare (O-LM) interneurons that provide a theta frequency patterned output to distal dendrites of pyramidal cells are endowed with(More)
A triple helix is formed upon binding of an oligodeoxynucleotide to the major groove of duplex DNA. A benzo[e]pyridoindole derivative (BePI) strongly stabilized this structure and showed preferential binding to a triplex rather than to a duplex. Energy transfer experiments suggest that BePI intercalates within the triple helix. Sequence-specific inhibition(More)
Understanding how ligands bind to G-protein coupled receptors (GPCRs) provides insights into a myriad of cell processes and is crucial for drug development. Here we extend a hybrid molecular mechanics/coarse-grained (MM/CG) approach applied previously to enzymes to GPCR/ligand complexes. The accuracy of this method for structural predictions is established(More)
The incident indirect light over a range of image pixels is often coherent. Two common approaches to exploit this inter-pixel coherence to improve rendering performance are Irradiance Caching and Radiance Caching. Both compute incident indirect light only for a small subset of pixels (the cache), and later interpolate between pixels. Irradiance Caching uses(More)
Figure 1: Automatic 3D material style transfer from different source images (insets) to a target 3D scene using our approach. Abstract This work proposes a technique to transfer the material style or mood from a guide source such as an image or video onto a target 3D scene. It formulates the problem as a combinatorial optimization of assigning discrete(More)
—Taking an image of an object is at its core a lossy process. The rich information about the three-dimensional structure of the world is flattened to an image plane and decisions such as viewpoint and camera parameters are final and not easily revertible. As a consequence, possibilities of changing viewpoint are limited. Given a single image depicting an(More)
We propose a novel rendering method which supports interactive BRDF editing as well as relighting on a 3D scene. For interactive BRDF editing, we linearize an analytic BRDF model with basis BRDFs obtained from a principal component analysis. For each basis BRDF, the radiance transfer is precomputed and stored in vector form. In rendering time, illumination(More)

Gallium Arsenide (GaAs) based microsensors, analog readout electronics, analog to digital converters and digital signal processors have been in development. Microsensors include accelerometers, infrared sensors, and micromachines with high speed sensing response, extreme temperature operation, and high radiation hardness.
Figure 1: Our approach automatically aligns a set of images (a) showing instances of one object class to a " reference image " (b) and constructs a subspace of shape and appearance (c). This subspace is used to guide manipulations of a different image (d). When painting a colored stroke, our subspace is used to propagate plausible colors to plausible(More)
