(now part of Elo TouchSystems) in the 1970s and now sold by numerous suppliers, opticaltouch systems offer many advantages when compared to other touch technologies. Many in the industry believe that, if not for two considerable drawbacks discussed below, opticaltouch technology would today be the dominant touch technology. Recent technology developments in optical-touch screens could pave the ...

main theme a fascinating topic. In Renaissance Europe the insane were frequently at large. The Age of Enlightenment, coinciding with the increased growth of cities, seems to have led to their confinement?and to intensified ill-treatment. The account of these developments enables Dr. Foucault to imply that the role of the doctor as a magician and as the protagonist of society's attitudes to the ...

The goal of this study is to define a wireless network architecture that can be deployed to enable contiguous coastal area network coverage for scientific, commercial, and homeland security (e.g. Coast Guard) applications within the United States Exclusive Economic Zone (EEZ), in a manner that is flexible, manageable, and affordable. As described in Reference 1, we intend to determine the archi...

Prostate tumors arise primarily in the peripheral zone (PZ) of the prostate, but 20-30% arise in the transition zone (TZ). Zone of origin may have prognostic value or reflect distinct molecular subtypes; however, it can be difficult to determine in practice. Using whole-genome gene expression, we built a signature of zone using normal tissue from five individuals and found that it successfully ...

Classical objects in computational geometry are defined by explicit relations. Several years ago the pioneering works of T. Asano, J. Matoušek and T. Tokuyama introduced “implicit computational geometry” in which the geometric objects are defined by implicit relations involving sets. An important member in this family is called “a zone diagram”. The implicit nature of zone diagrams implies, as ...

BACKGROUND To examine histomorphometrically the parapapillary region in human eyes. METHODOLOGY/PRINCIPAL FINDINGS The histomorphometric study included 65 human globes (axial length:21-37 mm). On anterior-posterior histological sections, we measured the distance Bruch's membrane end (BME)-optic nerve margin ("Gamma zone"), BME-retinal pigment epithelium (RPE) ("Beta zone"), BME-beginning of n...

A zone diagram of order n is a relatively new concept which was first defined and studied by T. Asano, J. Matoušek and T. Tokuyama. It can be interpreted as a state of equilibrium between n mutually hostile kingdoms. Formally, it is a fixed point of a certain mapping. These authors considered the Euclidean plane and proved the existence and uniqueness of zone diagrams there. In the present pape...

the relations of fibrolite-biotite are discussed by presenting data from the ardara aureole, nw ireland. biotite-fibrolite intergrowths are developed in all three aureole zones including: the outer kyanite-bearing andalusite zone, the middle kyanite-free andalusite zone and the inner prismatic sillimanite zone. a strain-assisted mechanism is proposed for the fibrolitisation of biotite in the ar...

Habitability varies dramatically with location and time in the universe. This was recognized centuries ago, but it was only in the last few decades that astronomers began to systematize the study of habitability. The introduction of the concept of the habitable zone was key to progress in this area. The habitable zone concept was first applied to the space around a star, now called the Circumst...
