Online auctions have demonstrated how e-commerce can transform business, and not merely transplanting conventional processes to a new medium. The resulting emergence and growth of diverse markets pose the intriguing question of what ‘shape’ a given market is in at a particular moment of development. The approach of Topological Analysis, which is based on the Star Plot method in data visualizati...

Inter-protein interactions in solution affect the auto-correlation function of Brownian tumbling not only in terms of a simple increase of the correlation time, they also lead to the appearance of a weak slow component ("long tail") of the correlation function due to a slowly changing local anisotropy of the microenvironment. The conventional protocol of correlation time estimation from the rel...

Escherichia coli cells treated with arsenate cannot tumble. The relationship between cellular adenosine 5'-triphosphate (ATP) level and the ability to tumble has been studied. (i) Cells incubated with arsenate completely lost their tumbling ability, and the cellular ATP level was decreased to less than 0.3 nmol/mg of protein. (ii) Incubation with 10 mM arsenate-1 mM phosphate reduced the cellul...

One of the main technical challenge in orbital debris removal (ODR) missions is how to capture a tumbling and drifting space object given several environmental and operational constraints. This paper focuses on the guidance of a robot manipulator in a preand postgrasp phases to capture and stabilize a drifting and tumbling space object with uncertain dynamics. A Kalman filter is used to estimat...

A lattice model for active matter is studied numerically, showing that it displays wetting transitions between three distinctive phases when in contact with an impenetrable wall. The particles in the model move persistently, tumbling with a small rate α, and interact via exclusion volume only. When increasing the tumbling rates α, the system transits from total wetting to partial wetting and un...

An analysis is given of the dynamical symmetry breaking of semi-simple gauge groups. We construct a class of renormalizable gauge theories for the dynamically broken topcolor and technicolor interactions. It is shown that a fourFermi interaction in the strong coupling phase emerges by the tumbling of semi-simple gauge groups in the low energy region. In our models the topcolor interaction provi...

The adaptation to a strong light is one of the essential characteristics of green algae, yet lacking relatively the information about the photophobic responses of Eukaryotic microalgae. We investigated the photophobic step-up responses of Euglena gracilis over a time course of several hours with alternated repetition of blue-light pulse illumination and spatially patterned blue-light illuminati...

Performing complex somersaulting skills during the flight phase of tumbling requires the generation of linear and angular momenta during the approach and takeoff phases. This paper investigates how approach characteristics and takeoff technique affect performance with a view to maximising somersault rotation in tumbling. A five-segment planar simulation model, customised to an elite gymnast, wa...
