Although much research has been devoted to designing and experimenting on ad hoc networks of tiny devices, very little has focussed on devising theoretical models to capture the inherent power and limitations of such networks. A notable exception is the po ...
Climate changes are expected to affect bird migration in several aspects including timing changes, breeding and migration orientation. The correlation analysis of several climate conditions (e.g. temperature, wind, humidity, etc) and bird migration traject ...
CCCTC-binding factor (CTCF) is a nuclear zinc-finger protein that displays insulating activity in a variety of biological assays. For example, CTCF-binding sites have been suggested to isolate Hox gene clusters from neighboring transcriptional interference ...
It is widely accepted that metabolic rates scale across species approximately as the 3/4 power of mass in most if not all groups of organisms. Metabolic demand per unit mass thus decreases as body mass increases. Metabolic rates reflect both the ability of ...
We report here infrared spectra of protonated and lithiated valine with varying degrees of hydration in the gas phase and interpret them with the help of DFT calculations at the B3LYP/6-31++G** level. In both the protonated and lithiated species, our resul ...
Changes in grazing management are believed to be responsible for declines in populations of birds breeding in grassland over the last decades. The relationships between grazing management regimes, vegetation structure and composition and the availability o ...
Cell interactions involving Notch signaling are required for the demarcation of tissue boundaries in both invertebrate and vertebrate development. Members of the Fringe gene family encode β-1,3 N-acetyl-glucosaminyltransferases that function to refine the ...
The buildup curves in QUIET-BIRD-NOESY expts., which are designed to isolate two-spin subsystems within macromols., are attenuated by transverse relaxation and evolution under homonuclear couplings during the bilinear rotation decoupling (BIRD) pulse sandw ...
Flocks of birds self-organize into V-formations when they need to travel long distances. It has been shown that this formation allows the birds to save energy, by taking advantage of the upwash generated by the neighboring birds. In this work we use a simp ...
The brain of a hibernating mammal withstands physiological extremes that would result in cerebral damage and death in a non-hibernating species such as humans. To examine the possibility that this neuroprotection results from alterations in cerebral metabo ...
