BACKGROUND Saliva represents an increasingly useful tool of diagnosis. Several factors such as salivary flow rates (SFRs) (unstimulated and stimulated) (U and S), pH, buffering capacity and consistency can be altered due to several disease processes or medications prescribed for various diseases. Alterations of SFRs, pH, buffering capacity and various ion concentrations can influence the pathog...

For positive constants c and d, the coefficients t and b will always assume values between 0 and 1. Such a buffering behavior, which is also characteristic of H+ buffering in pure water (Buffering II Supplement 2), was classified as “noninverting moderation” (Buffering I). The accompanying paper presented a general method to construct communicating vessel-models of noninverting moderation (Buff...

INTRODUCTION AND OBJECTIVES To characterize the viscoelastic properties of the aorta and pulmonary arteries and the effects of vascular smooth muscle activation on arterial buffering function. MATERIAL AND METHOD Aortic and pulmonary artery pressure and diameter were measured in six anesthetized sheep under baseline conditions, and during arterial hypertension induced by mechanical vascular o...

A new concept, that of "buffer capacity," is defined for potassium-buffering mechanisms in neural tissue. Buffer capacities for different mechanisms can be added and compared, thus simplifying quantitative assessment of diffusion, cytoplasmic uptake, and spatial buffering under varied conditions. The characteristic frequency components for potassium disturbances due to neural events are identif...

We propose a manifold regularization algorithm designed to work in an on–line scenario where data arrive continuously over time and it is not feasible to completely store the data stream for training the classifier in batch mode. The On–line Laplacian One–Class SVM (OLapOCSVM) algorithm exploits both positively labeled and totally unlabeled examples, updating the classifier hypothesis as new da...
