Established French loanwords in Sango - A pilot study

This study is an initial attempt to describe the established French loanwords in the lingua franca Sango, which is the main language spoken in the Central African Republic (CAR). It is a second language for the majority of the population of 3 million people for whom a great number of vernaculars serve as first languages. French loanwords in Sango are prompted by the contact between Sango and Frenc

Fourier meets Möbius: fast subset convolution

We present a fast algorithm for the subset convolution problem:given functions f and g defined on the lattice of subsets of ann-element set n, compute their subset convolution f*g, defined for S⊆ N by [ (f * g)(S) = [T ⊆ S] f(T) g(S/T),,]where addition and multiplication is carried out in an arbitrary ring. Via Möbius transform and inversion, our algorithm evaluates the subset convolution in O(n2

Homogenization of a dielectric mixture with anisotropic spheres in anisotropic background

This paper treats the problem of calculating the macroscopic effective properties of dielectric mixtures where both the inclusions and the background medium can be anisotropic. For this homogenization process, the Maxwell Garnett -type approach is used where the inclusions are assumed to be spherical and embedded in a homogeneous background medium. The anisotropy of the background medium has to be

Pictures and spoken descriptions elicit similar eye movements during mental imagery, both in light and in complete darkness

This study provides evidence that eye movements reflect the positions of objects while participants listen to a spoken description, retell a previously heard spoken description, and describe a previously seen picture. This effect is equally strong in retelling from memory, irrespective of whether the original elicitation was spoken or visual. In addition, this effect occurs both while watching a b

Costly steroids: egg testosterone modulates nestling metabolic rate in the zebra finch

The transfer of non-genetic resources from mother to the offspring often has considerable consequences for offspring performance. In birds, maternally derived hormones are known to influence a variety of morphological, physiological and behavioural traits in the chick. So far, the range of these hormonal effects involves benefits in terms of enhanced growth and competitive ability as well as costs
