only candidate for extreme point. The 1 st principal minors are –2, -3. The 1 st leading principal minor is –2. The 2 nd principal minors are 2 (confirm this). The 2 nd leading principal minor is +2. Therefore, this function satisfies the tests for a local maximum. Note also...
Examples: Find the stationary point on the curve : Step 1: Differentiate to give: Step 2: Put this equal to zero: Step 3: Solve: We now know that the stationary point is when . If we require the full co-ordinate we need to find the value of when . (We are looking for so we ...
In the class of all such algebras we find the abstract characterization for sets of functions having some fixed point or the same fixed point for all functions of the given sets.doi:10.1007/s000120050175Valentin S. TrokhimenkoBirkhäuser VerlagAlgebra Universalis...
In parallel, the sector RP phenotype could potentially be the end-point of "CSNB" phenotype in p.G90D. Nevertheless, the high occurrence of degeneration in our p.G90D cohort warrants caution in diagnosing p.G90D patients with CSNB without a longer follow up into adulthood. 3.4.2. Classic ...
In the analysis of spatial point patterns, it is generally assumed that the underlying spatial point process is “isotropic,” i.e., that all characteristics are homogeneous with respect to direction. However, this is known in ... Castelloe, John Mathias. - The University of Iowa. 被引量:...
In addition to the steady state solutions they discuss the transient stages of the gas flow immediately after onset or offset of the strong outgassing at the subsolar point. 展开 关键词: comet P/Halley anisotropic gas jets time variation of gas emission ...
This could point to higher iron levels in the (p)ppGpp0 mutant, which might be responsible for the growth delay in RPMI (Fig. 3C). Growth in RPMI medium was shown to mimic infection conditions of S. aureus in human plasma resulting in higher expression levels of iron-regulated genes [...
In other words, from a physical point of view, when the base tension of the string modeled by the equation is zero: a very realistic case. Last but not least no monotonicity assumption is required on $M$ and also this aspect makes the models more believable in several physical applications...
A restrictive assumption in change point analysis is "stationarity under the null hypothesis of no change-point", which is crucial for asymptotic theory but not very realistic from a practical point of view. For example, if change point analysis for correlations is performed, it is not necessari...
The information-theoretic Minimum Message Length (MML) principle leads to a general invariant Bayesian technique for point estimation. We apply MML to the problem of estimating the concentration parameter, κ , of spherical Fisher distri... DL Dowe,JJ Oliver,CS Wallace - Springer Berlin Heidelberg...
