The perceived speed of a ring of equally spaced dots moving around a circular path appears faster as the number of dots increases (Ho & Anstis, 2013, Best Illusion of the Year contest). We measured this "spinner" effect with radial sinusoidal gratings, using a 2AFC procedure where participants selected the faster one between two briefly presented gratings of different spatial frequencies (SFs) ...

Rho is a major small GTP-binding protein that is involved in the regulation of various cell functions, including proliferation and cell migration, through activation of multiple signaling molecules in various types of cells. We studied its roles in synovial fibroblasts (SFs) in patients with rheumatoid arthritis (RA) and clarified its relevance to RA synovitis, with the following results. 1)We ...

We present a new method for reconstructing depth of a known object from a single still image using deformed underneath sign matrix of a similar object. Existing Shape from Shading(SFS) methods try to establish a relationship between intensity values of a still image and surface normal of corresponding depth, but most of them resort to error minimization based approaches. Given the fact that the...

Recent studies have linked demographic changes and epidemiological patterns in bacterial populations using coalescent-based approaches. We identified 26 studies using skyline plots and found that 21 inferred overall population expansion. This surprising result led us to analyze the impact of natural selection, recombination (gene conversion), and sampling biases on demographic inference using s...

Some methods for demographic inference based on the observed genetic diversity of current populations rely on the use of summary statistics such as the Site Frequency Spectrum (SFS). Demographic models can be either model-constrained with numerous parameters, such as growth rates, timing of demographic events, and migration rates, or model-flexible, with an unbounded collection of piecewise con...

The aim of this paper is to attain a fast and realistic 3D face reconstruction, when only a limited set of images taken from multiple views, is available. Instead of much relying on merely 2D images as suggested by image-based modeling approaches, we investigate the used of several shape-from-shading (SFS) techniques, which have been studied extensively in computer vision researches. This is be...

AIM The assessment of social functioning and subjective quality of life in relation to symptomatic remission in schizophrenia patients after a first psychiatric hospitalization, as well as the analysis of connection between intensity of psychopathological symptoms and the level of functioning and quality of life, taking into account the status of remission and duration of illness. METHODS Six...

with a camera geometry transformation and by incorporating the stereo data as an initial estimate were investigated Based on the traditional problem formulation, it is difficult to integrate the two important vision cues, i.e., shading and by Shao et al. [17] and Leclerc and Bobik [9], respectively. stereo, for shape reconstruction due to conflicting albedo and Recently, Cryer et al. [2] propos...

Accurate real-time crash risk evaluation is essential for making prevention strategy in order to proactively improve traffic safety. Quite a number of models have been developed to evaluate traffic crash risk, by using real-time surveillance data. In this paper, the basic idea of traffic safety region is introduced into highway crash risk evaluation. Traffic safety region aims to describe the s...

Citicoline may be used in many neurological disorders. Combined treatment of citicoline with patching in amblyopia has previously been researched. The purpose of this paper is to illustrate the effect of citicoline in non-patching amblyopic patient. A 11-year-old amblyopic boy underwent complete ophthalmological examinations, including VEP with flash and pattern stimulus. Two averages of 100 sw...
