We introduce an algebra of data linkages. Data linkages are intended for modelling the states of computations in which dynamic data structures are involved. We present a simple model of computation in which states of computations are modelled as data linkages and state changes take place by means of certain actions. We describe the state changes and replies that result from performing those act...

Chimeric oligonucleotides containing phosphodiester and phosphorothioate linkages have been obtained using the solid phase synthesis. The oligonucleotide parts possessing natural internucleotide phosphate bonds were assembled using commercially available nucleoside 3'-O-(2-cyanoethyl-N,N-diisopropylamino)phosphoramidites 7 whereas the phosphorothioate segment was built using nucleoside 3'-O-(2-...

This paper is concerned with spatial linkages forming a closed loop. In one extreme configuration (deployed), these linkages form a frame of polygonal shape, such as a square or a hexagon, and in the other extreme (folded) configuration form a tight bundle. Throughout their motion range, they have mobility one. These linkages have potential applications for next-generation deployable spacecraft...

The present paper analyzes the forward linkages of a multinational’s investment in a resort which kicks off tourism activity in a LDC. We show that, under quite natural assumptions, overnight stays are increasing in the number of tourism related, differentiated goods and services supplied in equilibrium. These goods and services, if supplied by the local community, represent forward linkages of...

Our previous efforts have used in vitro selection to identify numerous Zn(2+)-dependent deoxyribozymes that ligate two RNA substrates with reaction at a 2',3'-cyclic phosphate. Each deoxyribozyme creates one of several different RNA linkages, including native 3'-5' and non-native 2'-5' phosphodiester bonds as well as many unnatural linkages. In this report, we describe experiments to reveal des...

Fisheries regulations driven by environmental concerns would not only directly affect fisheries sectors but also tend to indirectly influence other sectors through intersectoral input–output linkages. This paper examines both backward and forward linkages of Hawaii’s fisheries sectors to the rest of the economy, and based on this evaluates the potential economic impacts of longline fishing regu...

Organisation s value chains are part of a wider chain of events – value networks. This paper explores the role of Internet-related technologies (IRT) in improving inter-organisational linkages and information sharing across value networks and the impact it has on the level of product or service delivered to customers. Using case study findings, the paper illustrates how IRT have strengthened an...
