Discontinuous Maxwell–Rankine stress functions for space frames
This article shows how bending and torsional moments in three-dimensional frames can be represented via a discontinuous Maxwell–Rankine stress function. The associated Rankine reciprocal contains polygonal faces whose areas...

From a Weightless Bent Wire Coat Hanger to Shell Structures via the Beltrami Stress Tensor
A weightless wire coat hanger bent out of its plane is one of the simplest possible structures. All it does is transfer a force and moment around a closed space curve. Assembling a family of coat hangers enables us to build up...
Stability of trusses by graphic statics.
This paper presents a graphical method for determining the linearized stiffness and stability of prestressed trusses consisting of rigid bars connected at pinned joints and which possess kinematic freedoms. Key to the...
Graphic kinematics, visual virtual work and elastographics.
In this paper, recent progress in graphic statics is combined with Williot displacement diagrams to create a graphical description of both statics and kinematics for two- and three-dimensional pin-jointed trusses. We begin with...

The pedestrian-induced instability of the London Millennium Bridge is a widely used example of Kuramoto synchronisation. Yet, reviewing observational, experimental, and modelling evidence, we argue that increased coherence of...

Multiple origins of melanism in two species of North American tree squirrel ( Sciurus )
Abstract: Background: While our understanding of the genetic basis of convergent evolution has improved there are still many uncertainties. Here we investigate the repeated evolution of dark colouration (melanism) in eastern fox...

Development of a methodology for understanding the potency of risk connectivity
The Strategic Risk Register System (SRRS) is proposed by the writers as a practical methodology to enable the connectivity of risks to be elicited and evaluated so that the most potent risks in a system can be identified. The...
Clinical features and outcomes in 38 dogs with cholelithiasis receiving conservative or surgical management
Abstract: Background: Ursodeoxycholic acid is used in human medicine for litholytic management of choleliths, but the efficacy of medical management in dogs with cholelithiasis is unknown. Objectives: To describe the clinical...

Mar 21, 2014
Single crystals of the dithienylethene compounds, 1,2-bis(2- methylbenzothiophen-3-yl)perfluorocyclopentene 1 and 1,2-bis(2,5- dimethylthiophen-3-yl)perfluorocyclopentene 2 undergo pressure-induced single-crystal to...
