I present the current state of knowledge about narrow ( < ∼ 500 km s) ultraviolet absorption that is intrinsic to QSOs. I consider interpretations in the context of the accretion-disk/wind scenario of QSOs.

Shading and reflectance images, which are commonly called intrinsic images, are useful in many computer vision applications. A number of methods have been proposed to extract those images. Unfortunately, all of these methods assume diffuse only reflections and deem highlights to be outliers. To overcome the presence of highlights, usually reflection components separation is applied before attem...

objects have accidental intrinsic properties as long as the properties’ supervenience base is contingently configured too. What does the type-creationist take to be the supervenience base for repeatable artworks? The creative acts of artists are obviously part of it, but also relevant are the type’s embodiments, including the patterns of (re)production and modification. But given that these cre...

Accurate characterization of promoter behavior is essential for the rational design of functional synthetic transcription networks such as logic gates and oscillators. However, transcription rates observed from promoters can vary significantly depending on the growth rate of host cells and the experimental and genetic contexts of the measurement. Furthermore, in vivo measurement methods must ac...

We investigate the feasibility of probing the neutrino mixing angle φ13 and the mass hierarchy with observations of the neutrino bursts from a future supernova. The analysis is based on a density profile of relaxed inverse power-law, ρ ∼ r, to account for the uncertainty of n residing in the supernova mechanism. The survival probabilities of νe and ν̄e are shown to reduce to two-dimensional func...

The processes that develop and maintain the intrinsic electrical properties of neurons are modeled by allowing the maximal strength of membrane conductances to be slowly varying functions of the intracellular calcium concentration. The resulting dynamic regulation of conductances allows model neurons to self-assemble their membrane currents and to react to and recover from external perturbation...

Among properties computer vision attempts to extract from images are: local shape, intrinsic reflection parameters, and roughness because they are all crucial to the success of image interpretation in general and to realistic surface modeling in particular. We seek light reflection phenomena and reflectance models that could better capture the relation of reflected light parameters to the local...
