Structure-Antimicrobial Activity Relationships of Recombinant Host Defence Peptides Against Drug-Resistant Bacteria. [PDF]
Microb BiotechnolRecombinant constructs of Host defence peptides (HDPs) represent a valuable class of antimicrobial agents to address the growing threat of antimicrobial resistance (AMR). Structure–activity relationship (SAR) studies demonstrate that amphipathicity mainly explains the average antimicrobial activity against the Gram‐positive strains, and the exposed ...

Spectral properties of substitutions on compact alphabets
Bulletin of the London Mathematical Society, Volume 55, Issue 5, Page 2425-2445, October 2023., 2023 Abstract We consider substitutions on compact alphabets and provide sufficient conditions for the diffraction to be pure point, absolutely continuous and singular continuous. This allows one to construct examples for which the Koopman operator on the associated function space has specific spectral components.

Mathematics, 2020 In this manuscript we characterize the completeness of a normed space through the strong lacunary ( N θ ) and lacunary statistical convergence ( S θ ) of series. A new characterization of weakly unconditionally Cauchy series through N θ

On the pointwise entangled ergodic theorem [PDF]
, 2017 We present some twisted compactness conditions for almost everywhere convergence of one-parameter entangled ergodic averages of Dunford-Schwartz operators $T_0,\ldots, T_a$ on a Borel probability space of the form $$ \sum_{n=1}^N T_a^n A_{a-1}T_{a-1}^nA_{

Statistical Convergence of Double Sequences of Order
Journal of Function Spaces and Applications, 2013 We intend to make a new approach and introduce the concepts of statistical convergence of order and strongly -Cesàro summability of order for double sequences of complex or real numbers. Also, some relations between the statistical convergence of order

On the $\Delta _{{\Lambda ^2}}^f$-Statistical Convergence on Product Time Scale
Universal Journal of Mathematics and Applications, 2020 In this paper, we first define a new density of a $\Delta $-measurable subset of a product time scale ${\Lambda ^2}$ with respect to an unbounded modulus function.

Weighted modulus Sθ-convergence of order α in probability
Arab Journal of Mathematical Sciences, 2017 Let θ={kr}r∈N∪{0} be a lacunary sequence, ϕ be a modulus function and {tn}n∈N be a sequence of real numbers such that tn>δ,∀n∈N (where δ is a fixed positive real number) and Tn=t1+t2+⋯+tn (where n∈N and T0=0).

Pluripotential theory on the support of closed positive currents and applications to dynamics in $\mathbb{C}^n$ [PDF]
, 2017 We extend certain classical theorems in pluripotential theory to a class of functions defined on the support of a $(1,1)$-closed positive current $T$, analogous to plurisubharmonic functions, called $T$-plurisubharmonic functions.

Uniform families of ergodic operator nets
, 2012 We study mean ergodicity in amenable operator semigroups and establish the connection to the convergence of strong and weak ergodic nets. We then use these results in order to show the convergence of uniform families of ergodic nets that appear in ...

Generalized Lacunary Statistical Difference Sequence Spaces of Fractional Order
International Journal of Mathematics and Mathematical Sciences, 2015 We generalize the lacunary statistical convergence by introducing the generalized difference operator Δνα of fractional order, where α is a proper fraction and ν=(νk) is any fixed sequence of nonzero real or complex numbers.
