Some Bounds for the Kirchhoff Index of Graphs [PDF]

open access: yesAbstract and Applied Analysis, 2014
The resistance distance between two vertices of a connected graphGis defined as the effective resistance between them in the corresponding electrical network constructed fromGby replacing each edge ofGwith a unit resistor. The Kirchhoff index ofGis the sum of resistance distances between all pairs of vertices.

Salmonella lipopolysaccharide‐containing supported lipid bilayers as platforms to study bacteriophage interactions

open access: yesFEBS Letters, EarlyView.
We present robust protocols for the preparation of supported lipid bilayers (SLBs) incorporating either Salmonella smooth LPS or outer membrane vesicles (OMVs). We use a combination of quartz crystal microbalance with dissipation (QCM‐D) and fluorescence microscopy to both characterize the SLBs of various compositions and to probe their interactions ...

The boundary Riemann problem of the power-logarithmic order of infinity index for the half-plane

open access: yesLietuvos Matematikos Rinkinys, 2005
The boundary Riemann problem of the power-logarithmic order of infinity index for the half-plane in the class ℬ of bounded analytic functions and in the class ℬ0(ρ, n) ⊂ ℬ, is investigated.

Phosphoinositides and inositol phosphates as molecular glues

open access: yesFEBS Letters, EarlyView.
Inositol phosphates (IPs) and phosphoinositides (PIPs) regulate diverse eukaryotic processes. Beyond recruiting signaling proteins or acting as structural cofactors, recent studies suggest they mediate protein–protein interactions as natural molecular glues.

Sign changing solutions of the Hardy–Sobolev–Maz'ya equation

open access: yesAdvances in Nonlinear Analysis, 2014
In this article we will study the existence, multiplicity and Morse index of sign changing solutions for the Hardy–Sobolev–Maz'ya (HSM) equation in bounded domain and involving critical growth.

Structural insights and therapeutic targets in Acinetobacter baumannii capsule biosynthesis

open access: yesFEBS Letters, EarlyView.
Hypervirulent KL49 A. baumannii's capsular polysaccharide contains the nonulosonic acid 8‐epi‐Leg5,7Ac2, synthesized by epimerization via ElaA, ElaB, and ElaC. Crystal structures of ElaA, ElaB, and ElaC reveal their role in CMP‐Leg5,7Ac2 synthesis and regioselective C8 epimerization.

Cesàro Summable Sequence Spaces over the Non-Newtonian Complex Field

open access: yesJournal of Probability and Statistics, 2016
The spaces ω0p, ωp, and ω∞p can be considered the sets of all sequences that are strongly summable to zero, strongly summable, and bounded, by the Cesàro method of order 1 with index p.

On existence of positive solutions of coupled integral boundary value problems for a nonlinear singular superlinear differential system

open access: yesElectronic Journal of Qualitative Theory of Differential Equations, 2012
By constructing a special cone and using fixed point index theory, this paper investigates the existence of positive solutions of singular superlinear coupled integral boundary value problems for differential systems $$\left\{ \begin{array}{ll} -x''(t ...

Three phosphatase families form a community: The phosphohydrolases that act upon inositol pyrophosphates

open access: yesFEBS Letters, EarlyView.
Inositol pyrophosphates are energy‐rich signaling molecules that perform critical functions in cells. Three different families of phosphatases hydrolyze the β phosphate of the inositol pyrophosphate molecules: two have narrow specificities and one is promiscuous.

On the Ritt order of a certain class of functions

open access: yesInternational Journal of Mathematics and Mathematical Sciences, 1983
The authors introduce the notions of Ritt order and lower order to functions defined by the series ∑1∞fn(s)exp(−λns) where (λn) is a D-sequence and fn(s) are entire functions of bounded index.
