Reo is a language for coordinating autonomous components in distributed environments. Coordination in Reo is performed by circuit-like connectors, which are constructed from primitive, mobile channels with well-defined behaviour. While the structure of a connector can be modeled as a graph, its behaviour is compositionally defined using that of its primitive constituents. In previous work, we s...

Complex genetic networks consist of structural modules that determine the levels and timing of a cellular response. While the functional properties of the regulatory architectures that make up these modules have been extensively studied, the evolutionary history of regulatory architectures has remained largely unexplored. Here, we investigate the transition between direct and indirect regulator...

Joint connection methods, such as shear key and loop bar, improve the structural performance of precast concrete structures; consequently, there is usually decreased workability or constructional efficiency. This paper proposes a high-efficiency skewed pipe shear connector. To resist shear and pull-out forces, the proposed connectors are placed diagonally between precast concrete segments and a...

Taming complexity is a fundamental goal of software engineering. The core techniques that have been successful in practice are those that separate concerns, especially variants of architectural abstractions called components and connectors. We argue that General Theories of Software Engineering (GTSE) should be organized by components and connectors to distinguish conceptually distinct elements...

Belian wood is very well known building construction material and been used since long time ago for both structural non-structural elements. Somehow belian buildings which have being exist many years or some functional changes in use need strengthening. One of the most popular strengthening method concrete jacketing as it practical mechanically increase capacity existing structures. This resear...

BACKGROUND/AIM Increased airway resistance reduces the effectiveness of ventilation treatment. Endotracheal tubes (ETTs) and connectors contribute to resistance. However, the effect of a closed system suction (CSS) connector is not well known. We compared the in vivo resistance occurring with a CSS connector with that of the standard connector. MATERIALS AND METHODS This prospective study was...

OBJECTIVE The offset connector can allow medial and lateral variability and facilitate intralaminar screw incorporation into the construct. The aim of this study was to compare the biomechanical characteristics of C7 intralaminar screw constructs with and without offset connector using a three dimensional finite element model of a C6-7 cervical spine segment. METHODS Finite element models rep...

High-level G3X(MP2)-RAD calculations have been carried out to examine the effect of interposing a "connector" group (W) on the interaction between a substituent (X) and the radical center in carbon-centered radicals ((•)CH(2)-W-X). The connector groups include -CH(2)-, -CH═CH-, -C≡C-, -p-C(6)H(4)-, -m-C(6)H(4)-, and -o-C(6)H(4)-, and the substituents include H, CF(3), CH(3), CH═O, NH(2), and CH...
