Open AccessAccessing tens-to-hundreds femtoseconds nuclear state lifetimes with low-energy binary heavy-ion reactions
A novel Monte Carlo technique has been developed to determine lifetimes of excited states in the tens-to-hundreds femtoseconds range in products of low-energy heavy-ion binary reactions, with complex velocity ...

Influence of theatre hall layout on actors’ and spectators’ emotions
“Audience effect” is the influence of an audience size or composition on the emotional state of a public speaker. One characteristic of the audience which has received little attention is the spatial position ...

Age and social affinity effects on contact call interactions in free-ranging spider monkeys
Nonhuman primates’ vocal repertoire has shown little plasticity, with immatures producing adult-like acoustic structures. Yet, the use of different call types shows a degree of socially dependent flexibility d...

A proton density bubble in the doubly magic 34Si nucleus
Many properties of the atomic nucleus, such as vibrations, rotations and incompressibility, can be interpreted as due to a two-component quantum liquid of protons and neutrons. Electron scattering measurements...

Transfer-induced fission in inverse kinematics: Impact on experimental and evaluated nuclear data bases
Inverse kinematics is a new tool to study nuclear fission. Its main advantage is the possibility to measure with an unmatched resolution the atomic number of fission fragments, leading to new observables in th...

Open AccessBehavioural innovation and cultural transmission of communication signal in black howler monkeys
Social traditions based on communication signals are widespread in birds, cetaceans and humans, but surprisingly rare in nonhuman primates known for having genetically-determined vocal repertoires. This study ...

Social partner discrimination based on sounds and scents in Asian small-clawed otters (Aonyx cinereus)
Ability to discriminate familiar conspecifics is an essential competence in any group-living species, ensuring socio-spatial cohesion, but in many animals, such as mustelids, the relative importance of the dif...

Open AccessYoungsters do not pay attention to conversational rules: is this so for nonhuman primates?
The potentiality to find precursors of human language in nonhuman primates is questioned because of differences related to the genetic determinism of human and nonhuman primate acoustic structures. Limiting th...

Friendships between males and lactating females in a free-ranging group of olive baboons (Papio hamadryas anubis): evidence from playback experiments
Close association between an anoestrous female at the time of lactation and adult male(s) is relatively rare in mammals, but common in baboons (Papio hamadryas subsp.). The functional significance of these “frien...
