in this paper, we prove some coupled coincidence point theorems for mappings satisfying generalized contractive conditions under a new invariant set in ordered cone metric spaces. in fact, we obtain sufficient conditions for existence of coupled coincidence points in the setting of cone metric spaces. some examples are provided to verify the effectiveness and applicability of our results.

In this paper, we introduce the notion of weak $psi$-quasi contraction in generalized metric spaces and using this notion we obtain conditions for the existence of fixed points of a self map in $D$-complete generalized metric spaces. We deduce some corollaries from our result and provide examples in support of our main result.

We present in this contribution the results of the first experiment to monitor land subsidence along JingJin High Speed Railway (JingJin HSR), which connects Beijing city and Tianjin city and is the first high speed railway in China, by using the Permanent Scatterer InSAR (PSI). Since the length of the railway is usually beyond the standard scenes coverage of the ongoing radar satellite, i.e. E...

For a fixed nonnegative integer $m$, an analytic map $\varphi$ and function $\psi$, the generalized integration operator $I^{(m)}_{\varphi,\psi}$ is defined by \[ I^{(m)}_{\varphi,\psi} f(z) = \int_0^z f^{(m)}(\varphi(\zeta)) \psi(\zeta) \, d\zeta \] for $X$-valued $f$, where $X$ Banach space. Some estimates norm of $I^{(m)}_{\varphi,\psi} \colon wA^p_{\alpha}(X) \to A^p_{\alpha}(X)$ are obtain...

Evidence shows the presence on the chromosome of Methanobacterium wolfei of a defective prophage which, by DNA-DNA hybridization, is closely related to the virulent archaeophage psi M1 of Methanobacterium thermoautotrophicum Marburg. Partial sequencing of a M. wolfei 16S rRNA gene and phylogenetic analysis indicated that this organism is more closely related to other representatives of the genu...

In plants and cyanobacteria, two light-driven electron pumps, photosystems I and II (PSI, PSII), facilitate electron transfer from water to carbon dioxide with quantum efficiency close to unity. While similar in structure and function, the reaction centers of PSI and PSII operate at widely different potentials with PSI being the strongest reducing agent known in living nature. Photochemically i...

We build a new estimate for the normalized eigenfunctions of operator −∂xx + V(x) based on oscillatory integrals and Langer’s turning point method, where ∼ ∣x∣2ℓ at infinity with ℓ > 1. From this an improved reducibility theorem we show that equation $$\matrix{\hfill {{\rm{i}}{\partial _t}\psi = - \partial _x^2\psi V\left(x \right)\psi {{\left\langle x \right\rangle}^\mu}W\left({\nu x,\omega t}...

Semantic blogging combines blogs with the Semantic Web for improved metadata. Our analysis of six semblogging approaches and systems reveals that all are RDF-based, suffer from not using Published Subjects as proxies for subjects, and do not employ semantic relations motivated by knowledge organization. In contrast, we introduce and discuss semblog-tm, a prototype of a Topic Mapsand PSI-based s...
