Isoperimetric Inequalities of Euclidean Type in Metric Spaces

1.1. Statement of the main result. The isoperimetric problem of euclidean type for a space X and given classes Ik−1, Ik, and Ik+1 of surfaces of dimension k − 1, k, and k + 1 in X , together with boundary operators Ik+1 ∂ −→ Ik ∂ −→ Ik−1 and a volume function M on each class, asks the following: Does there exist for every surface T ∈ Ik without boundary, ∂T = 0, a surface S ∈ Ik+1 with ∂S = T a...

The Extension of a Cyclic Inequality to the Symmetric Form

Let n be a natural number such that n ≥ 2, and let a1, . . . an be positive numbers. Considering the notations Si1... ik = ai1 + · · ·+ aik , S = a1 + · · ·+ an, we prove certain inequalities connected to conjugate sums of the form: ∑ 1≤i1<···<ik≤n Si1... ik S − Si1... ik Then provided that 1 ≤ k ≤ n − 1 we give certain lower estimates for expressions of the above form, that extend some cyclic ...

The Odds Algorithm Based on Sequential Updating and Its Performance

Let I1, I2, . . . , In be independent indicator functions on someprobability space ( ,A,P). We suppose that these indicators can be observed sequentially. Furthermore, let T be the set of stopping times on (Ik), k = 1, . . . , n, adapted to the increasing filtration (Fk), where Fk = σ(I1, . . . , Ik). The odds algorithm solves the problem of finding a stopping time τ ∈ T which maximises the pro...

Investigation of linear and non-linear estimation methods in highly-skewed gold distribution

The purpose of this work is to compare the linear and non-linear kriging methods in the mineral resource estimation of the Qolqoleh gold deposit in Saqqez, NW Iran. Considering the fact that the gold distribution is positively skewed and has a significant difference with a normal curve, a geostatistical estimation is complicated in these cases. Linear kriging, as a resource estimation method, c...

NADH -supplementation decreases pinacidil-primed IK(ATP) in ventricular cardiomyocytes via increase of intracellular ATP content

The aim of this study was to investigate the effect of NADH-supplementation on the metabolic condition of isolated guinea pig ventricular cardiomyocytes using the pinacidil-primed IK(ATp) as an indicator of subsarcolemmal ATP concentration. Membrane currents were studied using the patch-clamp technique in the whole-cell recording mode at 36-37C. Under physiological conditions (4.3 mM ATP in the...
