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...
We obtain stronger results than by use of fixed point index and additionally get the existence of a connecting orbit.doi:10.1007/s10884-017-9573-7Aleksander ĆwiszewskiNicolaus Copernicus UniversityMateusz MaciejewskiNicolaus Copernicus UniversitySpringer USJournal of Dynamics and Differential Equations...
(i.e. the gradient is zero) you have a stationary point. In short: find the 1 st differential, put it equal to zero and solve. 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 ...
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...
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 ...

Aup1p Is Required for Efficient Survival in Long Term Stationary Phase Cultures—The role of autophagy and mitophagy in cell survival has been a point of some debate in the literature. Whereas some authors contend that autophagy is strictly a cell survival mechanism related to starvation stress, ...
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 [...
A node is a point in a stationary wave where particle is always at rest. 4. What are antinodes? An antinode is a point in a stationary wave where the particle has maximum amplitude. 5. What is the distance between successive nodes? Distance between two successive nodes is equal ...
But the parallel FP+FI+FD controller shows considerably much better set-point tracking response and does not deviate from steady state. Also, a huge spike is observed in the output of PID controller as the reference set-point and process parameters are changed, while the FP+FI+FD controller ...
