Robust image analysis of spots in microarrays (quality control + spot segmentation + quantification) is a requirement for automated software which is of fundamental importance for a high-throughput analysis of genomics microarray-based data. This paper deals with the development of model-based image processing algorithms for qualifying/segmenting/quantifying adaptively each spot according to it...

Though wireless spectrum is an untangible resource, it is typically assigned through licenses on a long-term basis and may be likened to a property of the licensee. The possibility to lease it temporarily through a secondary market makes it a virtualizable resource, exploitable by virtual operators. A crucial issue for the business propositions of virtual operators is spectrum pricing. Spectrum...

A naive implementation of a road pricing system will collect an enormous amount of personal location data. In this paper we present a sophisticated system that is privacy friendly, i.e. where the invoices contain aggregated pricing information and where only the driver has insight into all the underlying details. Enforcement based on spot checking is used to keep drivers honest, and to make the...

Cercospora leaf spot (CLS) is one of the most serious diseases of sugar beet worldwide, and if uncontrolled, causes nearly complete defoliation and loss of revenue for beet growers. The beet sugar industry continuously seeks CLS-resistant sugar beet cultivars as one strategy to combat this disease. Normally human experts manually observe and rate the resistance of a large variety of sugar beet ...

The neural mechanism that mediates perceptual filling-in of the blind spot is still under discussion. One hypothesis proposes that the cortical representation of the blind spot is activated only under conditions that elicit perceptual filling-in and requires congruent stimulation on both sides of the blind spot. Alternatively, the passive remapping hypothesis proposes that inputs from regions s...

BACKGROUND AND PURPOSE Recent studies have recommended both early and late imaging to increase spot sign detection. However optimal acquisition timing for spot detection and impact on outcome prediction is uncertain. Our aim was to assess the utility of CTP in spot sign detection and characterization with emphasis on its impact on the prediction of outcome in patients with acute primary ICH. ...

A time series of spectral observations are used to derive the spot distribution on both components of the active late-type binary system V824 Ara. Both stars show a spot distribution that is dominated by a polar spot whose center is displaced from the rotation axis of the star. This is similar to the spot distribution found on other young stars and may provide further support for the hypothesis...

W ith the recent surge of interest in wave-front sensing technology as a new diagnostic tool in refractive surgery 1,2 , the concept of wavefront customized correction has now come to the forefront. 3,4 Among the companies leading this effort, the Summit-Autonomous Technologies provides a technology platform within CustomCornea which can be used as a model for wavefront ablation requirements. A...
