This Viewpoint addresses two issues in comparing data from humans and animals in studies of cardiovascular physiology: 1) accuracy of methods and 2) limits in extrapolating data from one species to another. You are invited to submit a brief commentary on this Viewpoint, which will be reviewed by Journal of Applied Physiology editors for possible publication in the Journal. Please limit your com...

Slope stability analysis is a geotechnical engineering problem characterized by many sources ofuncertainty. In slope stability computations, some of these sources are encountered, such as geologicaldetails missed in the exploration program, estimation of soil properties that are difficult to quantifyand many other relevant factors. Therefore, accurate reproduction of the spatial variability in ...

context studies show that despite the role of mouth care in preventing ventilator-associated pneumonia, there is no high quality evidences for it. this study reviewed the literature related to mouth care in patients receiving mechanical ventilation. evidence acquisition pubmed, ovide, elsevier, proquest, iranmedex, sid, and magiran databases were searched using key terms such as oral care, mout...

Davis, Jedwab and Smith recently proved that there are no 2-dimensional Barker arrays except of size 2×2. We show that the existence of a (d+1)-dimensional Barker array implies the existence of a d-dimensional Barker array with the same number of ±1 elements. We deduce that there are no Barker arrays having more than two dimensions, as conjectured by Dymond in 1992.

Consider a polynomial of large degree n whose coefficients are independent, identically distributed, non-degenerate random variables having zero mean and finite moments of all orders. We show that such a polynomial has exactly k real zeros with probability n−b+o(1) as n → ∞ through integers of the same parity as the fixed integer k ≥ 0. In particular, the probability that a random polynomial of...
