The second-to-fourth digit ratio (2D : 4D) is a well-studied sexual dimorphism that likely arises as a result of prenatal androgenic effects on homeobox gene expression. This dimorphism has been found to exhibit interesting ...

Digit length ratios are organized during embryonic development and may show sexual dimorphism related to steroid exposure. The second-to-fourth digit length ratio (2D:4D) has received the most attention. In the present ...

Inter-temporal trade-offs are ubiquitous in human decision making. We study the relationship between preferences over such trade-offs and the ratio of the second digit to that of the forth (2D:4D), a marker for pre-natal ...

It is now well documented that androgen and estrogen signaling dur- ing early development cause a sexual dimorphism in second-to-fourth digit length ratio (2D:4D). It is also well documented that males of mam- malian ...

Los contadores de fotones semiconductores pixelados son un tipo de detector de partículas ampliamente usados en campos como la física, la ingeniería y la medicina. En específico, el detector Timepix3 de la familia de ...

Este estudio determina las características de los pulsos bipolares estrechos (NBEs) en Bogotá, Colombia, proporcionando información sobre los NBEs en una región tropical observada desde un altiplano andino. La instrumentación ...

Deforestation is a phenomenon that affects the integrity of aquatic ecosystems. However, little is known about how this process affects trophic interactions of organisms, especially in the tropics. Food webs are considered ...

Studies about justice and equality have been part of moral and political philosophy that proposes normative principles which show ought at the public context. These discussions tend for human dignity proposing changes ...
