H-Ras, N-Ras, and K-Ras are homologous signaling molecules that are able to regulate distinct signaling pathways because they inhabit different compartments within the cell. In their Perspective, Meder and Simons discuss new work ( Rocks et al .) showing that N-Ras and H-Ras continuously cycle between the plasma membrane and Golgi ...

Roundabout receptors (Robo) and their Slit ligands were discovered in the 1990s and found to be key players in axon guidance. Slit was initially described s an extracellular matrix protein that was expressed by midline glia in Drosophila. A few years later, it was shown that, in vertebrates and invertebrates, Slits acted as chemorepellents for axons ...

Abstract Purpose – Measures aimed at reducing intersection crashes have high potential to be cost effective since intersections constitute only a small part of the overall highway system but intersection-related crashes constitute more than 50% of all crashes in urban areas and over 30% in rural areas.

Cyclists’ perception of risk in roundabouts
Accident Analysis & Prevention, 2008Converting an intersection into a roundabout improves motor vehicle safety, but a similar safety effect is not found for car-bicycle collisions. Very little is known about the reasons behind these collisions. In this study a first step towards an understanding of the reasons behind these collisions is taken.

roundabout methods of production
1987Methods of production are roundabout if they use produced means of production or the services of capital goods as well as those of land and labour, the latter being considered original or primary factors of production.

History of the Present, 2022
Abstract The Gilets jaunes brought attention to the existence and demands of the popular classes as other than the deplorables of the far right. This essay examines the ideas of an innovative group of historians who interpret the Gilets jaunes as evoking and enacting the unresolved issues of the revolutions of 1789, 1848, and 1871 on the

Modern Suburban Roundabouts in Croatia - Flower and Turbo roundabouts
Scientific journal of civil engineering, 2019Turboroundabouts are specially designed multilane roundabouts with spiral circulatory roadway and physically separated traffic lanes. This roundabout layout was developed in the late nineties of the last century with the aim of increasing the traffic safety and capacity at classic multi-lane roundabouts.

Modeling gridlock at roundabout
Computer Physics Communications, 2015We propose a cellular automaton model to study the traffic patterns at a roundabout. We obtain the complete phase diagram which consists of four distinct phases: free flow, congestion, bottleneck, and gridlock. For the six possible transitions among these four phases, we observe only five transitions.

Modelling roundabout capacities. [PDF]
, 2015 There has been extensive research and development into the capacity of modern offside priority roundabouts since the 1970’s. Despite this, there remains a major gap in existing knowledge with regards to the factors and variables which affect roundabout entry capacity.
