The existing buffers algorithms cannot effectively to meet the demands of high accuracy buffer analysis in practice although many efforts have been made past 60 years. A generalized buffering algorithm (GBA) is presented, which considers geometric distance and attribute characteristics all instances within zone. proposed includes three major steps: (1) select initialize target instance; (2) det...

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...

[1] Snowmelt processes result in diel fluctuations in streamflow and stream stage that propagate into riparian aquifers and cause a daily pumping of the hyporheic zone. This diel pumping was observed in stream stage and water table records collected in Tuolumne Meadows, Yosemite National Park, California. A model was developed using Fourier analysis to represent the stream stage fluctuations an...

In plants, growth of roots and root hairs is regulated by the fine cellular control of pH and reactive oxygen species (ROS). MES, 2-(N-morpholino)ethanesulfonic acid as one of the Good's buffers has broadly been used for buffering medium, and it is thought to suit for plant growth with the concentration at 0.1% (w/v) because the buffer capacity of MES ranging pH 5.5-7.0 (for Arabidopsis, pH 5.8...

conclusions this was the first study that focused on expanding resilience indicators, and presents a new framework to simplify assessment of resilience and safety of a complex system. results in this study, 29 factors affecting this indicator were determined using the delphi method; the scores of all factors were less than the scores of the best practice. on the other hand, the state of this in...
