Live migration of virtual machines (VM) across distinct physical hosts is an important feature of virtualization technology for maintenance, load-balancing and energy reduction, especially so for data centers operators and cluster service providers. Several techniques have been proposed to reduce the downtime of the VM being transferred, often at the(More)
Previous investigations of parents' abilities to recognize the cries of their own babies have identified substantial and significant sex differences, with mothers showing greater correct recognition rates than fathers. Such sex differences in parenting abilities are common in non-human mammals and usually attributed to differential evolutionary pressures on(More)
Competence for genetic transformation seems to play a fundamental role in the biology of Streptococcus pneumoniae and is believed to account for serotype switching, evolution of virulence factors, and rapid emergence of antibiotic resistance. The initiation of competence is regulated by the quorum sensing system referred as the ComABCDE pathway.(More)
BACKGROUND Despite widespread evidence that gender stereotypes influence human parental behavior, their potential effects on adults' perception of babies' cries have been overlooked. In particular, whether adult listeners overgeneralize the sex dimorphism that characterizes the voice of adult speakers (men are lower-pitched than women) to their perception(More)
The emergence of joint attention is still a matter of vigorous debate. It involves diverse hypotheses ranging from innate modules dedicated to intention reading to more neuro-constructivist approaches. The aim of this study was to assess whether 12-month-old infants are able to recognize a "joint attention" situation when observing such a social(More)
We take a look at the properties of scalar fields in anti–de–Sitter space in five dimensions. More specifically we define bulk–to–boundary and bulk–to–bulk propagators for a five–dimensional scalar field and use these to calculate four–point functions. Finally we take a look at two–point functions and three–point functions and numerically calculate masses,(More)
Finding food resources and maintaining a balanced diet are major concerns for all animals. A compromise between neophobia and neophilia is hypothesised to enable animals to enlarge their diet while limiting the risk of poisoning. However, little is known about how primates respond to novel food items and whether their use is socially transmitted. By(More)
Saving the state of a running virtual machine (VM) for later restoration has become an indispensable tool to achieve balanced and energy-efficient usage of the underlying hardware in virtual desktop cloud environments (VDC). To free up resources, a remote user’s VM is saved to external storage when the user disconnects and restored when the user reconnects(More)
