Lattice structures are used in the design of metamaterials to achieve unusual physical, mechanical, or biological properties. The properties of such metamaterials result from the topology of the lattice structures, which are usually three-dimensionally (3D) printed. To incorporate advanced functionalities into metamaterials, the surface of the lattice structures may need to be ornamented with f...

The article presents a deposition of ornaments from the Late Nordic Bronze Age period V. An archaeological excavation along with non-pollen Palynomorph (NPP) and pollen ana-lysis has resulted in new knowledge about poorly illuminated tradition spring offerings. With starting point find at Hedegyden this aims to improve understanding depositional practices relation springs. ornaments, but focuse...

1. A growing number of studies suggest that female ornaments are linked to maternal quality and influence male mate choice. These findings challenge the traditional male-biased view of sexual selection and the hypothesis that female ornaments are the outcome of a genetic correlation with male ornaments. To further test the hypothesis that female traits have a function, it is now essential to in...

Males may use sexual displays to signal their quality to females ; the handicap principle provides a mechanism that could enforce honesty in such cases. Iwasa et al. 1] model the signalling of inherited male quality, and distinguish between three variants of the handicap principle: pure epistasis, conditional, and revealing. They argue that only the second and third will work. An evolutionary s...

The prehistoric site of Franchthi Cave located in the south-eastern Argolid in Greece yielded an exceptionally rich collection of personal ornaments. A reassessment of this category of material culture by two of us (CP and MV) led to the hypothesis that one type of personal ornaments, i.e. marine shell beads belonging to the species Cyclope neritea, were intentionally heated to change their nat...
