The stability behaviour of the functional equation F (y) − F (x) = (y − x)f ( (x+ y)/2 ) is studied. It is proved that this equation is superstable i.e. if f, F satisfy ∣∣F (y) − F (x)(y − x)f((x + y)/2)∣∣ ≤ ε then f satisfies this equation (with some F ). In order to obtain this result the equation h∆hf(x) = 0 is considered and it is proved that also this equation is superstable.

The results on the effectiveness of five 2D electrical resistivity tomography (ERT) survey profiles for Ag-Pb-Zn, fluorite, and barite exploration Mississippi Valley Type (MVT) magmatic deposits northeast Mexico, are presented. were made in areas with mining activities or mineralization outcrops. Schlumberger, dipole-dipole, Wenner array configurations used measurements. showed that electric ca...

In this paper, we describe our work developing an object-oriented parallel toolkit on OO-MPI. We are developing a parallelised implementation of the multi-view tomography toolbox, an iterative solver for a range of tomography problems. The code is developed in object-oriented C++. The MVT toolbox is presently used by researchers in the field of tomography to solve linear and non-linear forward ...

This study aimed at testing the hypothesis that differences in neural activation strategy during submaximal but not maximal plantarflexions exist between young and older men. Eleven young men (YM, 26 ± 4 years) and thirteen old men (OM, 76 ± 3 years) volunteered for the investigation. Maximal voluntary torque (MVT) was 38.2%, lower (p < 0.001) in OM than in YM, while voluntary activation was eq...

Mississippi Valley-type (MVT) ore deposits arc epigenetic carbonate-hosted Pb-Zn deposits that contain galena, sphalerite, fluorite, bar&e, dolomite, calcite, and quartz. Although they are thought to form from basinal brines, their exact origins are still unclear, partly because of the scarcity of reliable geochronological data. Rb-Sr dating of sphalerites has recently been shown to be a promis...

ICDs rely upon programmable rate cutoffs to direct therapy delivery. Studies showing reduced mortality when high voltage (HVT) is avoided have led programming that promotes longer detection times and higher rates. However, such can also result in delayed for hemodynamically compromising polymorphic VT (PVT) or ventricular fibrillation (VF). We aim characterize tachyarrhythmia (VTA) features dev...

The Marginal Value Theorem (MVT) is a cornerstone of biological theory. It connects the quality and distribution of patches in a fragmented habitat to the optimal time an individual should spend exploiting them, and thus its optimal rate of movement. However, predictions regarding how habitat alterations should impact optimal strategies have remained elusive, with heavy reliance on graphical ar...

The influence of contraction type on the human ability to use the torque capacity of skeletal muscle during explosive efforts has not been documented. Fourteen male participants completed explosive voluntary contractions of the knee extensors in four separate conditions: concentric (CON) and eccentric (ECC); and isometric at two knee angles (101°, ISO101 and 155°, ISO155). In each condition, to...
