Peanut is an allotetraploid (2n = 2x = 40, AABB) of recent origin. Arachis duranensis and A. ipaënsis, the most probable diploid ancestors of the cultigen, and several other wild diploid species with different genom...

Distributive Hilbert algebras with infimum, or DH^-algebras for short, are algebras with implication and conjunction, in which the implication and the conjunction do not necessarily satisfy the residuation law. These alg...

We compute the contact term of the two-point function for the SL (2, ℝ)- WZNW model in the winding sector. After reviewing some generalities of the model and its Euclidean counterpart, we discuss the reflection symmetr...

Some urbanization impacts on biodiversity are often underestimated such as noise pollution generated by anthropogenic activities. Birds inhabiting urban and peri-urban areas suffer anthropogenic noise that impact their c...

A set of coupled Brownian motors—resulting from a noise-induced phase transition generated through an entropic mechanism, and formerly studied in mean-field approximation—is numerically integrated by Heun’s method....

A survey of the elemental contents of K, Mg, Mn, Na, Cl, Br, Cs, Co, Rb, Fe, Zn, Al, Ti, V, As, Ag, Au and Cd in liver, kidney and muscle was performed in specimens of Commerson's dolphins (Cephalorhynchus c. commersonii...

The philosophy of neuroscience has been a dynamic field of research in the philosophy of science since the turn of the century. As a result of this activity, a new mechanistic philosophy has emerged as the dominant appro...

Brood reduction is a within-brood partial mortality due to sibling rivalry and has been observed in a large number of bird species from diverse taxa. Here, I summarize several hypotheses accounting for the adaptive value...
