this study investigated metadiscourse and its subcategories in english research articles (ras) written by nonnative (iranian) and native english writers from the two disciplines of applied linguistics and civil engineering. the study aimed at seeing whether language and discipline influenced the frequency of occurrence of metadiscourse elements in research articles. to this end, a sample of 120...

Root system architecture is a trait that displays considerable plasticity because of its sensitivity to environmental stimuli. Nevertheless, to a significant degree it is genetically constrained as suggested by surveys of its natural genetic variation. A few regulators of root system architecture have been isolated as quantitative trait loci through the natural variation approach in the dicotyl...

In this paper we present a multilingual natural language interface architecture, which can be used for accessing on line product catalogs and lets users formulate their queries in their native languages. In our interface architecture a rule based machinelearning module replaces an elaborate semantic analysis component. The learning module learns the correct mappings of a user’s input to the cor...

The design and implementation of the transport layer of a native ATM protocol stack and its embedding into an overall architecture that provides end-to-end quality of service (QOS) is presented. Within this architecture, the typical transport functionalities are enlarged with QOS monitoring and adaptation mechanisms. A QOS-based application programming interface is proposed that shields applica...

Flash SSDs are omnipresent as database storage. HDD replacement is seamless since Flash SSDs implement the same legacy hardware and software interfaces to enable backward compatibility. Yet, the price paid is high as backward compatibility masks the native behaviour, incurs significant complexity and decreases I/O performance, making it non-robust and unpredictable. Flash SSDs are black-boxes. ...

In an age of comparative microbial genomics, knowledge of the near-native architecture of microorganisms is essential for achieving an integrative understanding of physiology and function. We characterized and compared the three-dimensional architecture of the ecologically important cyanobacterium Prochlorococcus in a near-native state using cryo-electron tomography and found that closely relat...

This paper describes the implementation and testing of a highspeed simulator for a reconfigurable processor architecture named MCGREP. The architecture is based on a coarse-grained array of small processors controlled by reconfigurable microcode. A high-speed simulator is needed to allow complex experiments to be carried out on MCGREP, involving large applications and time-consuming computation...

Support for anycast in the IP network layer allows one source node to contact a single member out of a group of destination nodes configured with the same IP address. Due to the stateless nature of the IP protocol, subsequent packets from the same source node targeted at the same anycast group may arrive at different group members. Consequently, native IP anycast cannot be applied directly to s...

Developmental patterning and differentiation, maintenance of parenchymal cell function, and the size, shape, and invasiveness of tumors are all orchestrated by cell interactions with the extracellular matrix. Here we show that the fibrillar structure of fibronectin (FN) matrix encodes essential regulatory cues and controls cell proliferation and signaling through changes in matrix architecture....
