In the above model, h(x, y) is the point-spread function (PSF) of the system, n(x, y) is an additive random noise, a is a constant describing the overall change of contrast, τ stands for a transform of spatial coordinates due to projective imaging geometry and ∗ denotes 2D convolution. In many application areas, it is desirable to find a description of the original scene that does not depend on...

It is generally accepted that the left ventricle (LV) hypertrophies (LVH) to normalize systolic wall stress (sigma(s)) in chronic pressure overload. However, LV filling pressure (P(v)) may be elevated as well, supporting the alternative hypothesis of end-diastolic wall stress (sigma(d)) normalization in LVH. We used an LV time-varying elastance model coupled to an arterial four-element lumped-p...

OBJECTIVE Qualitative studies can help us understand the "successes" and "failures" of telemedicine to normalize within clinical service provision. This report presents the development of a robust conceptual model of normalization processes in the implementation and development of telemedicine services. DESIGN Retrospective and cumulative analysis of longitudinal qualitative data from three s...

Cross-orientation suppression was measured in human primary visual cortex (V1) to test the normalization model. Subjects viewed vertical target gratings (of varying contrasts) with or without a superimposed horizontal mask grating (fixed contrast). We used functional magnetic resonance imaging (fMRI) to measure the activity in each of several hypothetical channels (corresponding to subpopulatio...

INTRODUCTION Two (2) quantum theoretically based metaphor/models have been proposed recently to describe the therapeutic process in homeopathy in terms of (1) a representation of the vital force (Vf) as a spinning quantized gyroscope, describable as a wave function; and (2) a form of nonorthodox quantum theoretical entanglement (called PPR entanglement) between the patient, practitioner, and re...

The advantages of Remote Sensing for the knowledge of environmental dynamics are widely ascertained by scientific community. Spatial synchronization and temporal resolution of large areas have meaningfully improved quantity and quality of satellite imagery which have assumed an important role in the field of environmental monitoring. Nevertheless, preliminary processing problems of multitempora...

In this paper, we study the scattering and absorption sections of Schwarzschild--anti de Sitter black hole surrounded by quintessence. The critical values cosmological constant normalization factor are obtained. We describe event horizons extremal condition effects quintessence on classical semi--classical cross--sections have been estimated. Also, section is studied with sinc approximation in ...

Differential conductance spectroscopy performed in the high bias regime---in which applied voltage exceeds sample work function---is a suboptimal measure of local density states due to effects changing tunnel barrier. Additionally, large oftentimes makes constant-height measurement experimentally impractical, lending constant-current an advantageous edge; but differential that case is even furt...
