Fixed points and completeness on partial metric spaces [PDF]
, 2015 Recently, Suzuki [T. Suzuki, A generalized Banach contraction principle that characterizes metric completeness, Proc. Amer. Math. Soc. 136 (2008), 1861-1869] proved a fixed point theorem that is a generalization of the Banach contraction principle and ...

FEBS Open Bio, EarlyView.Amino acids sequence of two different proteins with the same sequence (chameleon sequence—black boxes) represent in 3D structure of the proteins different secondary structures: HHHH—helical and BBB—Beta‐structural. The chains folded in water environment adopt different III‐order structures in which the chameleon fragments appear to adopt similar status

Some Common Fixed Point Theorems in Partial Metric Spaces
Journal of Applied Mathematics, 2011 Many problems in pure and applied mathematics reduce to a problem of common fixed point of some self-mapping operators which are defined on metric spaces.

Partially ordered metric spaces produced by T0-quasi-metrics
Topology and its Applications, 2016 A \textit{partially ordered metric space} is a triple \((X,m,\leqslant)\) where, as expected, \((X,m)\) is a metric space and \((X,\leqslant)\) is a partially ordered set. Given a set \(X\), a function \(d: X \times X \rightarrow [0,\infty)\) is said to be a \textit{quasi-pseudometric} if (a) \(d(x,x) = 0\) for all \(x \in X\); and (b) \(d(x,z ...

FEBS Open Bio, EarlyView.ERα splice variant ERα∆7 lacks the C‐terminus, and its expression may change phenotypes of breast cancers. Our results showed that ERα∆7 is found in the luminal A subtype, and elevated ERα∆7 levels are linked to improved cell survival with lower proliferation and migration.

An Improvement of Recent Fixed Point Results in Double-Composed Partial Metric Spaces
International Journal of Mathematics and Mathematical SciencesMore recently, a new concept of double-composed partial metric space has been introduced, and the related Banach type and Kannan type fixed point results have been established.

Partial Metrics Viewed as w-Distances: Extending Some Powerful Fixed-Point Theorems
MathematicsInvolving w-distances and hybrid contractions that combine conditions of the Ćirić type and Samet et al. type, we obtain some general fixed-point results for quasi-metric spaces from which powerful and significant fixed-point theorems on partial metric ...

FEBS Open Bio, EarlyView.This protocol paper outlines methods to establish the success of a time‐resolved serial crystallographic experiment, by means of statistical analysis of timepoint data in reciprocal space and models in real space. We show how to amplify the signal from excited states to visualise structural changes in successful experiments.

Linear and Nonlinear Perturbed Wave Equations
, 2008 We consider several Cauchy problems for the wave equation with some perturbation. First of all, we consider the wave equation with a metric perturbation, that is, we consider the d'Alembert operator in the Schwarzschild metric (which is a model for a ...

Configuration spaces of thick particles on graphs [PDF]
, 2011 In this thesis, we study the topology of configuration spaces of particles of variable radius r>0 moving on a metric graph. Our main tool is a piecewise linear (PL) Morse-Bott theory for affine polytope complexes, which extends the Morse theory for such ...
