The retail trade fully participates in the international competition between world's major cities, whether it be by wealth generates, or ways reveals city and regional territorial displays. One can argue that department stores had demonstrated this 19th century, while recently mega-shopping malls show a wide range of public private actors involved (metropolitan, national …) development project,...

Although the role of IT is salient in sporting mega-events (e.g. instant replay, goal-line technology), IS research has not yet paid any attention to the processes by which technologies are selected for and implemented at these mega-events, the strategies used by actors, nor the consequences of such implementations on actors in related sectors and industries. To tackle this underdeveloped resea...

To compare parasitism and inflammatory process in esophagus and colon from chronic chagasic patients, immunohistochemistry was carried out to research for T. cruzi and to evaluate the inflammatory infiltrate in the muscular and myenteric plexus in 39 esophagi (20 with and 19 without megaesophagus) and 50 colons (25 with and 25 without megacolon). The frequency of T. cruzi in megaesophagus was 2...

Development of science and technology and the growing trend of globalization has pushed the urban communities toward competition on absorbing foreign capitals and construction of macro-scale projects. This competition has affected not only developed countries but also developing countries such as Iran- since it is expected that each urban development will finally result in an increase in the qu...

Vertebrate claudin proteins are integral components of tight junctions, which function as paracellular diffusion barriers in epithelia. We identified Megatrachea (Mega), a Drosophila transmembrane protein homologous to claudins, and show that it acts in septate junctions, the corresponding structure of invertebrates. Our analysis revealed that Mega has transepithelial barrier function similar t...

We describe the development of a hardware turbo decoder on a field-programmable gate array for high-speed free-space laser communications. This system will be used by NASA’s Mars Laser Communications Demonstration project on the Mars Telecommunication Orbiter, the first use of high-speed laser communication from deep space. The error-correction code design has been shown to perform within 0.9 d...

Infrastructure mega projects involve several complex clusters of interacting activities. Establishing suitably integrated management support systems for construction clients should be useful in targeting best value with reduced rework and wastages. This paper presents highlights from a co-ordinated cluster of ongoing Hong Kong based research initiatives that aims to develop an integrated Manage...
