Proper partitioning of the contents of a cell between two daughters requires integration of spatial and temporal cues. The anaphase array of microtubules that self-organize at the spindle midzone contributes to positioning the cell-division plane midway between the segregating chromosomes. How this signalling occurs over length scales of micrometres, from… (More)
Gradients are used in a number of biological systems to transmit spatial information over a range of distances. The best studied are morphogen gradients where information is transmitted over many cell lengths. Smaller mitotic gradients reflect the need to organize several distinct events along the length of the mitotic spindle. The intracellular gradients… (More)
This paper explores the design of visualizations that support mandated organizational compliance processes. We draw on the research literature to show how visualizations can operate as effective user interfaces for complex, distributed processes. We argue that visualizations can reduce the complexity of such processes, making them easier to manage, and can… (More)
Automatic Vehicle Classification (AVC) systems provide data about vehicle classes that are used for many purposes. This paper describes a prototype axle count and spacing AVC system using wireless accelerometers and magnetometers. The accelerometers detect vehicle axles and the magnetometers report vehicle arrivals and departures and estimate speed. The… (More)

Some call it low power-design, some call it energy efficient design, and some call it green design. No matter what you call it, in today's complex systems and chips, power management, analysis, and exploration needs to be addressed early in the design cycle. To meet the overall power demands semiconductor designers and architects need to step up and deliver… (More)
Studies in fission and budding yeast have continuously led the way for analyzing pathways of cell division. Two elegant studies, one from each yeast species, are opening the gates to study one of the final steps of mitosis--silencing the spindle checkpoint.
