L^p inequalities for polar derivatives of polynomials [PDF]
Mathematical Inequalities & Applications, 2000 Let \(p(z)=a_0+a_1z+ \cdots+ a_nz^n\) be a polynomial of degree \(n\) and let for fixed \(\alpha\in\mathbb{C}\) \[ D_\alpha p(z):= np(z)+(\alpha-z)p'(z) \] denote the polar derivative of \(p(z)\) with respect to \(\alpha\). In this paper some inequalities for such polar derivatives are presented. In particular it is proved: Theorem.

FEBS Letters, EarlyView.The physical dimensions and shape of bacterial cells define the surface area available to acquire nutrients and the volume available for synthesizing proteins and DNA. Here, we use computational systems biology to decode the importance of cell geometry as a major determinant of prokaryotic phenotype, including growth rate and metabolic efficiency. This

FEBS 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 ...

Phosphoinositides and inositol phosphates as molecular glues
FEBS 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.

Polar form of Dirac fields: implementing symmetries via Lie derivative [PDF]
We consider the Lie derivative along Killing vector fields of the Dirac relativistic spinors: By using the polar decomposition we acquire the mean to study the implementation of symmetries on Dirac fields.

Self-assembly and semiconductivity of an oligothiophene supergelator
Beilstein Journal of Organic Chemistry, 2010 A bis(trialkoxybenzamide)-functionalized quaterthiophene derivative was synthesized and its self-assembly properties in solution were studied. In non-polar solvents such as cyclohexane, this quaterthiophene π-system formed fibril aggregates with an H ...

Computing the Fréchet Derivative of the Polar Decomposition
, 2016 We derive iterative methods for computing the Fréchet derivative of the map which sends a full-rank matrix $A$ to the factor $U$ in its polar decomposition $A=UH$, where $U$ has orthonormal columns and $H$ is Hermitian positive definite. The methods apply to square matrices as well as rectangular matrices having more rows than columns.
