The orientation of GNSS satellites in space is a key quantity data processing. It required to correctly apply several force models and observation corrections. Incorrect or insufficient modeling satellite attitude can lead inconsistencies both among providers products between users, which negatively affects the quality combined positioning solutions. Exchanging information form quaternions help...

To clarify the relationship between erythrocyte Na+/K+-ATPase activity and haematological findings, several clinical laboratory examinations were performed on 31 male workers employed in a scrap lead refining factory and, as controls, 50 male workers employed in railway construction. The results were: (1) Values for erythrocyte Na+/K+-ATPase activity, blood and urine lead, urine delta-aminolaev...

Some evidence indicates that the inotropic effect of cardiac glycosides occurs at concentrations too low to affect Na+,K+-ATPase activity. This suggests that some receptor other than Na+,K+-ATPase mediates the inotropic effect. We studied ouabain binding to sarcolemma-enriched preparations from canine ventricle under conditions known to promote binding to Na+,K+-ATPase. Profiles for binding and...

This paper introduces the linearity analysis of a progressive successive approximation registers (SAR) simple toadvanced converters (ADC) with part DAC structure taking into account two exchanging techniques: conventional charge-redistribution and Vcm-based switching. The static linearity execution, in particular the fundamental nonlinearity and differential nonlinearity, and in addition the pa...

Longitudinal exchange experiments facilitate the quantification of the rates of interconversion between the exchanging species, along with their longitudinal relaxation rates, by analyzing the time-dependence of direct correlation and exchange cross peaks. Here we present a simple and robust alternative to this strategy, which is based on the combination of two complementary experiments, one wi...

This paper describes ongoing work toward the development of a standard software exchange format (SEF), for exchanging information among tools that analyze computer programs. A particular exchange format called GXL (Graph Exchange Language) is proposed. GXL can be viewed as a merger of well known formats (e. g. GraX, PROGRES, RPA, RSF, and TA) for exchanging typed, attributed, directed graphs. B...

We show that O(n) exchanging flips suffice to transform any edge-labelled pointed pseudo-triangulation into any other with the same set of labels. By using insertion, deletion and exchanging flips, we can transform any edge-labelled pseudo-triangulation into any other with O(n log c+h log h) flips, where c is the number of convex layers and h is the number of points on the convex hull.

RENKIN, EUGENE M. Exchangeability of tissue potassium in skeletal muscle. Am. J. Physiol. 1g7(6): I~II-12 15. I g5g.-The quantity of ‘rapidly exchanging’ Kf in isolated, skeletal muscles of dogs was determined by measuring the back-diffusion of K42 during perfusion with blood containing this isotopic tracer. This quantity was not constant, but varied from da/$ to 88y0 of the total tissue K+. Th...
