When parents invest heavily in reproduction they commonly suffer significant energetic costs. Parents reduce the long-term fitness implications of these costs through increased foraging and reduced reproductive investment in the future. Similar behavioral modifications might be expected among helpers in societies of cooperative vertebrates, in which helping is associated with energetic costs. B...

Due to the pandemic phenomenon that occurred after December 2019, wearing a mask became commonplace, and virus is blocked, but it causes other problems. As number of respiratory problems skin from masks increases, expected people with weak will have diseases psychological effects on trouble.

Little is known about the neurobiological mechanisms underlying prosocial decisions and how they are modulated by social factors such as perceived group membership. The present study investigates the neural processes preceding the willingness to engage in costly helping toward ingroup and outgroup members. Soccer fans witnessed a fan of their favorite team (ingroup member) or of a rival team (o...

Helping hosts are intensively used in various schemes to restore partitioned Mobile Ad Hoc Networks (MANETs). Most of the existing schemes offers only deterministic deployment and fixed routes for the helping hosts, and are thus not able to deal with fluctuating network traffic, which is a practical condition in many MANET applications. In this paper, we argue that flexible helping hosts (refer...

Coordinate structures are linguistic structures consisting of two or more conjuncts, which usually compose into larger constituent as a whole unit. However, the boundary of each conjunct is difficult to identify, which makes it difficult to parse the whole coordinate and larger structures. In labeled data, such as the Penn Chinese Tree Bank (CTB), coordinate structures are not labeled explicitl...
