Let F2 be the finite field of cardinality 2 . For all large n, any subset A ⊂ F2 × F n 2 of cardinality |A| & 4 log log n log n , must contain three points {(x, y) , (x + d, y) , (x, y + d)} for x, y, d ∈ F2 and d 6= 0. Our argument is an elaboration of an argument of Shkredov [14], building upon the finite field analog of Ben Green [10]. The interest in our result is in the exponent on log n, ...

Colour polymorphisms are known to influence receiver behaviour, but how they affect a receiver's ability to detect and recognize individuals in nature is usually unknown. I hypothesized that polymorphic female damselflies represent an evolutionary stable strategy, maintained by trade-offs between the relative apparency of morphs to male receivers. Using field experiments on Enallagma hageni and...

Glass microelectrodes filled with a saturated solution of methyl blue or fast green in 1.0M potassium acetate can be used to mark penetrated ne. urons from which intracellular recordings have been made. Many cells can be marked in one experiment and can easily be located in subsequent histologic section.

Observers adapted to a field of randomly coloured twinkling tiles, in which was embedded a faint, subthreshold green letter. Observers failed to discern this letter, but they readily reported its pink afterimage afterwards. This demonstrates a storage of changing colours over time; adaptation occurs for the average of each retinal point.

Nowadays, the growing computational capabilities of Cloud systems rely on the reduction of the consumed power of their data centers to make them sustainable and economically profitable. The efficient management of computing resources is at the heart of any energy-aware data center and of special relevance is the adaptation of its performance to workload. Intensive computing applications in dive...

Employing cytochemical methods it was found that during the early embryonic development of Drosophila melanogaster the nuclei contain in sequence two kinds of chromosomal proteins. The cleavage nuclei (as also the pronuclei), until shortly before the blastoderm stage, contain an atypical (or juvenile) histone, stainable with bromophenol blue but not with alkaline fast green. The typical fast gr...

The green sturgeon (Acipenser medirostris) is a highly migratory, oceanic, anadromous species with a complex life history that makes it vulnerable to species-wide threats in both freshwater and at sea. Green sturgeon population declines have preceded legal protection and curtailment of activities in marine environments deemed to increase its extinction risk. Yet, its marine habitat is poorly un...

In this paper we describe a new incentive-based pollution control program in China, in which the environmental performance of firms is rated from best to worst using five colors--green, blue, yellow, red and black--and the ratings are disseminated to the public through the media. We focus on the first two municipal disclosure programs, which have been implemented at very different levels of eco...

I n 1609, while exploring the lake that now bears his name, Samuel de Champlain looked to the east and exclaimed, “Voila les vert monts.” The Green Mountain State was an inhospitable place at that time; few dared to settle there until after the end of the French and Indian War, in 1763. By 1771, the population of Vermont was 4667 people. They led a difficult existence, and the earliest surgeons...

Closed-form solutions for the transient dynamic problems of a suddenly applied anti-plane concentrated force and concentrated impulse near a crack are obtained. The various wave signals comprising the solutions are identified, and their behavior noted. The concentrated force solution is then employed as a Green's function to solve the important problem of arbitrary screw dislocation motion near...
