This paper describes a new project to analyze the vast corpus of human manipulation videos available on the web, using citizen scientists. Humans understand human manipulation well enough to segment videos appropriately, to assign intent, and to recognize actions even from poor imagery. A large corpus of analyzed human manipulation would add to our understanding of manipulation, support automat...

This paper explains in detail a biologically inspired encoding scheme for the artiicial evolution of neural network robot controllers. Under the scheme, an individual cell divides and moves, in response to protein interactions with an artiicial genome, to form a multi-cellularòrganism'. After diierentiation dendrites grow out of each cell, guided by chemically sensitive growth cones, to form co...

Tidal stream speeds in straits are accelerated because of geographic and bathymetric features. For instance, narrow channels and shallows can cause high tidal stream energy. In this study, water level and tidal current were simulated using a three-dimensional semi-implicit Eulerian-Lagrangian finite-element model to investigate the complex tidal characteristics in the Taiwan Strait and to deter...

Vertisols occur extensively in centralIndiaand have high production potentials. Because of the high clay content (40-60% or more), high bulk density (1.5-1.8 Mg m-3) and related properties, these soils have high moisture storage capacity. Conversely, these soils become very hard when dry and very sticky when wet. Since last two decades, scientists, farmers and also the policy makers have be...

Might it be possible to harness the visual system to carry out artificial computations, somewhat akin to how DNA has been harnessed to carry out computation? I provide the beginnings of a research programme attempting to do this. In particular, new techniques are described for building 'visual circuits' (or 'visual software') using wire, NOT, OR, and AND gates in a visual 6modality such that ou...

This paper analyses folksonomies, an emergent web 2.0 technology. Folksonomies are found to be primarily a social dynamic phenomenon, and several key tensions are hypothesised that keep the folksonomy community vibrant. Strengths and weaknesses of folksonomies are analyzed w.r.t applicability to browsing and search, and suggestions are given on how to alleviate search problems by bringing in ad...

Freezing of atmospheric water on bituminous construction and road surfaces is a recurring event during winter. However, droplet freezing bitumen passive inhibition methods are poorly understood. Here we investigate relative humidity substrate cooling effects condensation subzero temperature find that explosive, with rapid local heating. We explain the related physics rate can affect sizes tempe...

Abstract For mechanical waves, Willis coupling means a cross-coupling between stress and velocity or momentum strain. In contrary to its realization in acoustic elastic whether exists water as another kind of wave, is still unknown. Here, we propose establish the concept waves horizontal at free surface acceleration potential vertical displacement flux. Thanks wave feature proposed metamaterial...

The formation of small 1 to 3 nm organic-ligand free metal-oxide nanocrystals (NCs) is essential utilization their attractive size-dependent properties in electronic devices and catalysis. We now report that hexaniobate cluster-anions, [Nb6O19]8−, can arrest the growth NCs stabilize them as water-soluble complexes. This exemplified by hexaniobate-complexed 2.4-nm monoclinic-phase CuO (1), whose...

Directed evolution of a cyanobacterial phytochrome was undertaken to elucidate the structural basis of its light sensory activity by remodeling the chemical environment of its linear tetrapyrrole prosthetic group. In addition to identifying a small region of the apoprotein critical for maintaining phytochrome's native spectroscopic properties, our studies revealed a tyrosine-to-histidine mutati...
