background Arginine-vasopressin(avp) is a physiological co-activator of the hypothalamus-pituitary-adrenal-axis(hpa), together with corticotrophin-releasing hormone (crh). A synthetic analogue of avp, desmopressin(ddavp) is often used as pharmacological tool to assess co-activation in health and disease. The relation between ddavp’s neuroendocrine, cardiovascular, pro-coagulatory, antidiuretic ...

Latent relational search (LRS) is a novel approach for mapping knowledge across two domains. Given a source domain knowledge concerning the Moon, “The Moon is a satellite of the Earth”, one can form a question {(Moon, Earth), (Ganymede, ?)} to query an LRS engine for new knowledge in the target domain concerning the Ganymede. An LRS engine relies on some supporting sentences such as “Ganymede i...

We set up recursion relations for the partition function and the ground-state occupancy for a fixed number of noninteracting bosons confined in a square box potential and determine the temperature dependence of the specific heat and the particle number in the ground state. A proper semiclassical treatment is set up which yields the correct small-T behavior in contrast to an earlier theory in Fe...

1. INTRODUCTION Madagascar's imperilled biota are now experiencing the effects of a new threat—climate change (Raxworthy et al. 2008). With more than 90% endemism among plants, mammals, reptiles and amphibians, the stakes are high. The pristine landscapes that allowed this exceptional biodiversity to survive past climate changes are largely gone. Deforestation has claimed approximately 90% of t...
