Colonization is the crucial process underlying range expansions, biological invasions, and metapopulation dynamics. Which individuals leave their natal population to colonize empty habitats is a crucial question and is presently unresolved. Dispersal is the first step in colonization. However, not all dispersing individuals are necessarily good colonizers. Indeed, in some species, the phenotype...

The S49 mouse lymphoma mutant cell line Kin- is resistant to the cytotoxic effects of elevated cAMP levels, has no detectable cAMP-dependent protein kinase activity, and has depressed levels of cAMP-binding regulatory subunits. We demonstrate that although the Kin- cell line lacks detectable catalytic subunit protein, these cells express wild-type levels of mRNA for both C alpha and C beta cata...

Zebrafish larvae imprint on visual and olfactory kin cues at day 5 and 6 postfertilization, respectively, resulting in kin recognition later in life. Exposure to non-kin cues prevents imprinting and kin recognition. Imprinting depends on MHC class II related signals and only larvae sharing MHC class II alleles can imprint on each other. Here, we analyzed which type of olfactory sensory neuron (...

Kin caregivers can provide continuity and connectedness for children who cannot remain with their parents. This is one reason kinship care has become the preferred placement option for foster children. However, despite the growing reliance on kin caregivers, kinship care policies have evolved with little coherent guidance. This article examines kinship care and finds: Kinship foster parents ten...

Cooperative alliances among kin may not only lead to indirect fitness benefits for group-living species, but can also provide direct benefits through access to mates or higher social rank. However, the immigrant sex in most species loses any potential benefits of living with kin unless immigrants disperse together or recruit relatives into the group in subsequent years. To look for evidence of ...

The logic of inclusive fitness suggests that people should be attentive to the mating relationships of their kin—especially their genetically closest kin. This logic further suggests that people will be especially attentive to close kin members' relationships when a greater indirect fitness benefit is at stake. Three studies tested implications of this analysis. The primary results were that (a...

Supervised by Dr. Yilong Yin Email:[email protected] School of Computer Science and Technology, Shandong University Jinan 250100, China Abstract This report shows our solution to PAKDD Competition 2007. Following a brief description of the data mining task, we discuss four difficulties to be dealt with in this task. Then, we show how to do the data pre-processing. To weaken class-imbalance of th...

oxidative Medicine and celluar Longevity 227 Derived from classical Chinese philosophy and with frequent applications in Chinese medicine, " yin yang " has grown into an interesting concept that may have a number of applications. The term is usually used to depict the existence of polarizing or opposing forces in nature. Yet, the concept of " yin yang " can be much more involved, especially in ...

The recent paper (Cheung 2001) has studied the blind identification of Gaussian source process through a general temporal independent component analysis (ICA) approach named dual autoregressive modelling. It is actually a temporal extension of the classical principal component analysis without considering the principal order of the components. In this paper, we will further show the identifiabl...
