Connector colouring provided an intuitive semantics of Reo connectors which lead to effective implementation techniques, first based on computing colouring tables directly, and later on encodings of colouring into constraints. One weakness of the framework is that it operates globally, giving a colouring to all primitives of the connector in lock-step, including those not involved in the intera...

Orthogonal connectors are used in a variety of common network diagrams. Most interactive diagram editors provide orthogonal connectors with some form of automatic connector routing. However, these tools use ad-hoc heuristics that can lead to strange routes and even routes that pass through other objects. We present an algorithm for computing optimal object-avoiding orthogonal connector routings...

The automotive environment is particularly demanding on connector performance, and is characterized by large temperature changes, high humidity and corrosive atmospheres. This paper presents an initial study of connector performance in terms of temperature profiles taken from road vehicles. The temperature profiles are then simulated using empirical relationships to allow prediction of connecto...

During replication of the ϕ29 bacteriophage inside a bacterial host cell, a DNA packaging motor transports the viral DNA into the procapsid against a pressure difference of up to 40 ± 20 atm. Several models have been proposed for the underlying molecular mechanism. Here we have used molecular dynamics simulations to examine the role of the connector part of the motor, and specifically the one-w...

The head-tail connector of bacteriophage phi29 is composed of 12 36 kDa subunits with 12-fold symmetry. It is the central component of a rotary motor that packages the genomic dsDNA into preformed proheads. This motor consists of the head-tail connector, surrounded by a phi29-encoded, 174-base, RNA and a viral ATPase protein, both of which have fivefold symmetry in three-dimensional cryo-electr...

Various types of optical connector with a precise alignment mechanism and long-term reliability have been researched, developed and improved during about 30 years since practical optical communication systems were first introduced in Japan in 1981. The main issues related to optical fiber connector development changed from performance improvement to miniaturization, cost reduction and ease of f...

The surfaces of two- and three-dimensional phi29 connector crystals were imaged in buffer solution by atomic force microscopy (AFM). Both topographies show a rectangular unit cell with dimensions of 16.5 nm x 16.5 nm. High resolution images of connectors from the two-dimensional crystal surface show two connectors per unit cell confirming the p42(1)2 symmetry. The height of the connector was es...

The Commonwealth Health Insurance Connector Authority is the centerpiece of Massachusetts' ambitious health care reforms, which were implemented beginning in 2006. The Connector is an independent quasi-governmental agency created by the Massachusetts legislature to facilitate the purchase of affordable, high-quality health insurance by small businesses and individuals without access to employer...

The notion of connector can be found in many of the contemporary component-based systems. A connector is an architectural element, which embodies communication among components in a system. In this paper we propose a flexible connector model that is easy to use in practice and expressive enough to capture the semantics of component interconnections. Our model follows the top-down approach to so...

This connector is named after its designers, Paul Neill of Bell Labs and Carl Concelman of Amphenol. The “B” originally stood for “baby” but was changed to “bayonette” after the TNC connector was introduced to distinguish the bayonet fasteni...
