A broad class of supersymmetric extensions of the standard model predict a Z 0 vector boson whose mass is naturally in the range 250 GeV<MZ0<2 TeV. To avoid unacceptably large mixing with the Z, one requires either a discrete tuning of the U(1)0 charges or a leptophobic Z 0. Both cases are likely to arise as the low energy limits of heterotic string compacti cations, but a survey of existing re...

A broad class of supersymmetric extensions of the standard model predict a Z ′ vector boson whose mass is naturally in the range 250 GeV<MZ′<2 TeV. To avoid unacceptably large mixing with the Z, one requires either a discrete tuning of the U(1) charges or a leptophobic Z . Both cases are likely to arise as the low energy limits of heterotic string compactifications, but a survey of existing rea...

The “Care Delivery Frame (CDF)” presented here integrates two distinctly different applications, the home telehealth system and the remote photo sharing service of digital photo frame, to create a unique information channel for senior users who are not familiar with the operation of computers and Internet. In addition to health data monitoring, children or caregivers can “deliver care” to their...

We present first experiences from Local Area Artworks, a system enabling collaborative art interpretation on-site, deployed during an exhibition in a local art gallery. Through the system, we explore ways to re-connect people to local places by making use of their personal mobile devices as interfaces to the shared physical space. With a collocated collaborative writing system in the semi-publi...

background: hyperbilirubinemia, or jaundice, is a life threatening disorder in newborns. it is a multifactorial disorder with many symptoms. generally, the physiological jaundice is the most prevalent type however in some regions pathological jaundice is also common. this review article focuses on a brief introduction to jaundice, its types and causes, measuring the bilirubin level, clinical ap...

several methods have been employed for cancer treatment including surgery, chemotherapy and radiation therapy. today, recent advances in medical science and development of new technologies, have led to the introduction of new methods such as hormone therapy, photodynamic therapy (pdt), treatments using nanoparticles and eventually combinations of lasers and nanoparticles. the unique features of...

A new photo-reactive polymer, polyvinylalcohol modified with phenylazido groups, was synthesized as a microarray matrix. The polymer is soluble in water and spin-coated onto glass plate. Aqueous solutions of proteins were micro-spotted onto the coated glass and were fixed by ultraviolet light irradiation. Subsequently, cell adhesion on the photo-immobilized protein microarray was investigated. ...
