Protandry is the emergence or arrival into a seasonal population of males before females and is widespread among both plants and animals. Conceptually, protandry should be subject to stabilizing selection because early emerging males risk death before mating and late-emerging males miss opportunities to mate. However, for any given male, the optimal emergence time may depend upon the mean and d...

We propose a Cellular Automata (CA) model in which three ubiquitous and relevant processes in nature are present, namely, spatial competition, distinction between dynamically stronger and weaker agents and the existence of an inner resistance to changes in the actual state Sn (=−1,0,+1) of each CA lattice cell n (which we call inertia). Considering ensembles of initial lattices, we study the av...

Detecting static structure deformed shape is very important to reduce properties and loss of human life. We can use a video camera to early catch emergence situations. Closed-circuit television (CCTV), also known as video surveillance, is the use of video cameras to transmit a signal to a specific place. We can get a sequence of images using CCTV and analyze the relationship between images in t...

to determine the optimum weed management method and plant population density on chickpea yield, a split plot experiment based on rcbd with four replications was carried out at the university of tehran research farm (located in karaj) during 2010-2011. the main factor consisted of nine treatments including: 1. trifluralin pre-plant, 2. pendimethalin pre-plant, 3. complete weeding, 4. imazethapyr...

in order to study of effects of integrated biological and chemical  fertilizers on  fertilizer use efficiency, grain yield and related traits to  grain growth of barley (hordeum vulgaris l.), a factorial experiment was conducted based on randomized complete block design with three replications in research farm of the faculty of agriculture sciences, university of mohaghegh ardabili in 2012. tre...

the effect of electromagnetic field was examined on zinnia (zinnia elegans) seeds to enhance seed germination and early growth. the seeds were exposed to four magnetic strengths of 15, 100, 400 and 800 mt in four durations of 30, 60, 120 and 240 min. the experiments were carried out in two forms of laboratory germination and soil emergence. results showed that magnetic field application enhance...

Finding models of a predicate logic formula is a well-known hard problem, whose complexity is exponential in the number of variables. However, even though this number is kept constant, substantial differences in complexity arise when searching for solutions in different problem instances. Such a behavior appears to be quite general, according to recent results reported in the literature; in fac...

We study the recently discovered q-deformed Poincaré supersymmetry of the AdS3/CFT2 integrable massless scattering, and demonstrate how the S-matrix is invariant under boosts. The boost generator has a non-local coproduct, which acts on the scattering matrix as a differential operator, annihilating it. We propose to reinterpret the boost action in terms of covariant derivatives on bundles, and ...

As new forms of social interaction with sound are developed through hardware, software and ubiquitous technologies it follows that emergent behavior, gesture capture and motion tracking will increasingly play a compositional role within generative and reactive sound environments. This case study defines an adaptive system, which enables participants within these spaces to have a tangible influe...

A major trend in mobile advertising is the emergence of real time bidding (RTB) based marketplaces on the supply side and the corresponding programmatic impression buying on the demand side. In order to acquire the most relevant audience impression at the lowest cost, a demand side player has to accurately estimate the win rate and winning price in the auction, and incorporate that knowledge in...
