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.

Golgi enzymes are retrieved from the plasma membrane to the trans‐Golgi network
FEBS Letters, EarlyView.Golgi enzymes are traditionally considered resident proteins retained within the Golgi apparatus. Here, we demonstrate that a subset transiently reaches the cell surface and is subsequently retrieved to the trans‐Golgi network via retrograde transport. Using a nanobody‐based toolkit, we uncover a dynamic trafficking cycle of several Golgi enzymes.

Polar bears killed in Svalbard 1987–1992
, 1993 A total of 26 polar bears have been killed in Svalbard since January 1987. Fifteen of these cases were self defense, four precautionary measures, six acts of mercy and one unknown.

Improved versions of certain Bernstein and Turán-type inequalities on polynomials
Open MathematicsIn this paper, we establish some new results on Bernstein and Turán-type inequalities for polynomials on the unit circle on the complex plane by using an improved Schwarz Lemma at the boundary recently proved by Mercer.

Stability Criteria for the Control of Multi-Fractional-Order Systems with Multiple State Delays
MathematicsThis paper aims to investigate a multiple fractional derivative order system control with multiple delays. The generalized Lyapunov function and YkP lemma are used to obtain algebraic and frequency criteria for asymptotic stability for these systems ...

Inequalities for the polar derivative of a polynomial with restricted zeros
, 2016 For a polynomial p(z) of degree n, we consider an operator Dα which map a polynomial p(z) into Dαp(z) := (α-z)p'(z)+ np(z) with respect to α. It was proved by Liman et al. [A. Liman, R. N. Mohapatra and W. M.

Emerging experimental and computational methods for studying redox‐regulated structural transitions
FEBS Letters, EarlyView.Redox reactions can reshape proteins and alter how they behave in cells, with important consequences for health and disease. This review explores emerging experimental and computational approaches for discovering these redox‐sensitive protein switches, revealing their structural effects, and predicting their behavior, opening new opportunities to ...

The interplay of global and polar regimes
, 1999 The growing salience of interactions between the functionally broad but geographically narrow regimes for the polar regions and the geographically broad but functionally specific regimes emerging to deal with global environmental changes directs ...
