Male homosexual behaviour-although found in most extant clades across the Animal Kingdom-remains a conundrum, as same-sex mating should decrease male reproductive fitness. In most species, however, males that engage in same-sex sexual behaviour also mate with females, and in theory, same-sex mating could even increase male reproductive fitness if males improve their chances of future heterosexu...

Choosing mates is a commonly shared behavior across many organisms, with important fitness consequences. Variations in female preferences can be due in part to differences in neural and cellular activity during mate selection. Initial studies have begun to identify putative brain regions involved in mate preference, yet the understanding of the neural processes regulating these behaviors is sti...

Man-At-The-End (MATE) attacks and fortifications are difficult to analyze, model, and evaluate predominantly for three reasons: firstly, the attacker is human and, therefore, utilizes motivation, creativity, and ingenuity. Secondly, the attacker has limitless and authorized access to the target. Thirdly, all major protections stand up to a determined attacker till a certain period of time. Digi...

Yerba mate (Ilex paraguariensis A. St.-Hil.) is an important subtropical tree crop cultivated on 326,000 ha in Argentina, Brazil and Paraguay, with a total yield production of more than 1,000,000 t. Yerba mate presents a strong limitation regarding sequence information. The NCBI GenBank lacks an EST database of yerba mate and depicts only 80 DNA sequences, mostly uncharacterized. In this scenar...

In the five years since it was proposed, the MATE scheme for anaphoric annotation has been used in a variety of annotation projects, and the resulting corpora have been used to study both anaphora resolution and NL generation. Annotation tools inspired by the proposals have been used in some of these projects. In this paper we discuss these first experiences with the scheme, some lessons that h...

Abstract—This paper presents the solution approach and implementation strategy followed in the development of the OVNI (“Object Virtual Network Integrator”) power system simulator. OVNI’s aim is to represent full-size power system networks for real-time and online simulation. To cope with the dimensions of the problem, partitioning techniques are required, both in the system solution and in the...

Two studies tested evolutionary hypotheses about the use and perceived effectiveness of specific mate attraction tactics as a function of sexual strategy pursued. Participants and a close same-sex friend of each participant reported on the participant’s sexual strategy and deployment of attraction tactics. In Study 1, participants’ mate attraction tactics differed predictably depending on wheth...

The Dark Triad – narcissism, Machiavellianism, and psychopathy – have traditionally been considered to be undesirable traits. However, emerging work suggest that not only may there be a positive side to possessing these traits but they may also serve important adaptive functions, even if the strategies associated with them are viewed as socially undesirable. In an online survey (N = 336), we in...

Programming parallel/distributed applications is a difficult task that requires a high degree of knowledge and expertise, especially to achieve the potential performance offered by HPC. Analysis and tuning tools can be helpful for automatically improving applications performance. In particular, dynamic analysis and tuning tools are necessary for applications that vary their behaviour at executi...
