Abstract Short-period comet 108P/Ciffreo is known for its peculiar double morphology, in which the nucleus accompanied by a comoving, detached, diffuse “blob.” We report new observations of taken with Hubble Space Telescope and Nordic Optical use them to determine cause this unusual morphology. The separation longevity blob across several orbits together rule out possibility single, slow-moving...

The flash-lag effect -- a misperception that a flashed object appears to lag behind a moving object despite their physical alignment -- has mainly been investigated as a spatiotemporal offset. Here, we report that the flash-lag-in-depth effect is accompanied by an illusory change in the apparent size of the flashed object. We found a strong flash-lag-in-depth effect with a dot-defined square, w...

We describe a method for estimation of 3-D geometry from 2-D blob features. Blob features are clusters of similar pixels in the image plane and can arise from similarity of color, texture, motion and other signal-based metrics. The motivation for considering such features comes from recent successes in real-time extraction and tracking of such blob features in complex cluttered scenes in which ...

introduction: voxel based morphometry is a type of statistical parametric mapping that can be used to investigate the effect of diseases such as epilepsy, alzheimer's disease and parkinson's disease or other agent such as skills on brain structure (white matter, gray matter and cerebrospinal fluid). the aim of this study is evaluate the effectiveness of this method in detection of dif...

To help understand the role of long-range, clustered lateral connections in the superficial layers of macaque striate cortex (area V1), we have examined the relationship of the patterns of intrinsic connections to cytochrome oxidase (CO) blobs, interblobs, and ocular dominance (OD) bands, using biocytin based neuroanatomical tracing, CO histochemistry, and optical imaging. Microinjections of bi...

Conventional seated audiences have relatively restricted opportunities for response. Perhaps the most salient is applause but they use their hands to make other visible movements: to fix hair, adjust glasses, scratch ears. The question we address here is whether these apparently incidental movements may provide systematic clues about an audience’s level of engagement with a performance. We inve...

Warning: This draft is draftier than you might expect. More specifically, • Some sections are missing. • Many sections are incomplete. In most cases the incompleteness is noted, but occasionally it isn’t. • Some sections were written nearly two years ago, and are now outdated. • There are not yet enough citations to similar work of other people. Despite all this, there’s probably enough deciphe...

Implicit surfaces have proved to be a particularly well suited and efficient model for animating and morphing shapes of arbitrary topologies. The Blob-Tree model is characterized as a hierarchical combination of skeletal primitives organized in a tree. The nodes hold blending, boolean and warping operators, which allows the design of complex objects. In this paper, we address the metamorphosis ...

objectives: this study sought to assess the diagnostic accuracy of cone beam computed tomography (cbct) with different voxel sizes and intraoral digital radiography with photostimulable phosphor (psp) plate for detection of periapical (pa) bone lesions. materials and methods: in this ex vivo diagnostic study, one-millimeter defects were created in the alveolar sockets of 15 bone blocks, each wi...
