We analyze 2-dimensional Ginzburg-Landau vortices at critical coupling, and establish asymptotic formulas for the tangent vectors of the vortex moduli space using theorems of Taubes and Bradlow. We then compute the corresponding Berry curvature and holonomy in the large area limit.

five subspecies of the persian jird, meriones persicus, were reported from iran. these subspecies were described based on morphological characters and coat colors of few specimens. the question of the validity of these subspecies and their geographic distribution is raised. in this study, we combined genetic markers (cox1, cytb and irbp genes), morphometric (external and skull measurments), mor...

V. vinifera L. 'Barbera', 'Croatina', 'Malvasia di Candia aromatica', growing in the Piacenza viticultural area (North-West Italy) at four elevations (150, 240, 320, 420 m a.s.l.), were tested at harvest for grape stilbene (trans-resveratrol, trans-piceid, cis-piceid) synthesis over three years (2000-2002). Meteorological data were recorded, as well as vine production and fruit quality paramete...

grape vine is one of the important horticultural crops with unique standing as regards use and consumption. the fruit is utilized from immature to ripened state and as raisins. its leaves can be used when they are soft and fresh. therefore it is necessary to improve iranian grapevine quality as well as quantity. the main purpose of this study was the use of phenyl phetalamic acid (ppa) to incre...

Population differences in visual environment can lead to divergence in multiple components of animal coloration including signalling traits and colour patterns important for camouflage. Divergence may reflect selection imposed by different receivers (conspecifics, predators), which depends in turn on the location of the colour patch. We tested for local adaptation of two genetically and phenoty...

In this paper, I investigate the use of artificial neural networks in the study of prey coloration. I briefly review the anti-predator functions of prey coloration and describe both in general terms and with help of two studies as specific examples the use of neural network models in the research on prey coloration. The first example investigates the effect of visual complexity of background on...
