Avian nests are frequently concealed or camouflaged, but a number of species builds noticeable nests or use conspicuous materials for nest decoration. In most cases, nest decoration has a role in mate choice or provides thermoregulatory or antiparasitic benefits. In territorial species however, decorations may serve additional or complementary functions, such as extended phenotypic signaling of...

We study the dynamics of island nucleation in the presence of adsorbates using kinetic Monte Carlo simulations of a two-species growth model. Adatoms (A-atoms) and impurities (B-atoms) are codeposited, diffuse and aggregate subject to attractive AAand AB-interactions. Activated exchange of adatoms with impurities is identified as the key process to maintain decoration of island edges by impurit...

We consider dynamic scenes consisting of moving points whose motion is constrained to happen in one of a pencil of planes. This is for example the case when rigid objects move independently, but on a common ground plane (each point moves in one of a pencil of planes parallel to the ground plane). We consider stereo pairs of the dynamic scene, taken by a moving stereo system, that allow to obtai...

The presence, forms and techniques used in artificial cranial deformation and dental decoration were studied in 1,515 skeletons found in 94 mostly pre-Hispanic archeological sites (in Mexico, Guatemala and Honduras) dating from the Preclassical, Classic and Postclassic periods. Biographical and associated archeological information was analyzed, based on a theoretical model of biocultural intera...

there is no doubt that colors are important factors in creating arts including poetry. the poets use them because of their visual beauties to show their hidden values. sometimes they go further – beyond the external features – ad use colors as symbols to express their own meaning. moreover, modern poet’s deep insight and vision are the main causes to change the colorful portrait to a bright won...

In this paper we discuss the geometric decoration of some Mycenaean artifacts, having a remarkable six-fold symmetry, probably suggested by the observation of the natural form of the honeycomb of beehives. In particular, we will discuss a decoration of a gold roundel, made by means of a compass, that looks like the Flower of Life of sacred geometry.

This work takes place in the context of an industrial project, which aims to decorate 3D plastic objects using Insert Molding technology. The goal of our work is to compute the decoration of 3D virtual objects, using data coming from polymer film characterisation and mechanical simulation. To do this, we introduce a new method to bind texture mapping techniques to a physical process. In the gen...

Phosphoethanolamine (PEA) decoration of lipid A produced by Neisseria gonorrhoeae has been linked to bacterial resistance to cationic antimicrobial peptides/proteins (CAMPs) and in vivo fitness during experimental infection. We now report that the lptA gene, which encodes the PEA transferase responsible for this decoration, is in an operon and that high-frequency mutation in a polynucleotide re...

On the base of the residential interior decoration and the air pollution status in China, as the requirements of indoor air quality at present are increasing, from the concept of healthy house, new idea is proposed that indoor air pollution is controlled by overall process through green interior design, selecting environmentally friendly materials and green decoration for safety, healthy and en...
