Secondary Frequency and Voltage Control of Islanded Microgrids via Distributed Averaging [PDF]

open access: yesIEEE transactions on industrial electronics (1982. Print), 2015
In this paper, we present new distributed controllers for secondary frequency and voltage control in islanded microgrids. Inspired by techniques from cooperative control, the proposed controllers use localized information and nearest-neighbor ...

Secondary Metabolites: The Natural Remedies

open access: yesSecondary Metabolites [Working Title], 2022
The chapter discusses the meaning and origin of some important classes of secondary metabolites such as alkaloids, terpenoids, tannins, flavonoids, saponins, glycosides, and phenolic compounds, etc., produced by some bacteria, fungi, or plants.

Hybrid bounds for automorphic forms on ellipsoids over number fields [PDF]

open access: yes, 2011
We prove upper bounds for Hecke-Laplace eigenfunctions on certain Riemannian manifolds of arithmetic type. The manifolds under consideration are d-fold products of 2-spheres or 3-spheres, realized as adelic quotients of quaternion algebras over totally ...

Quaternion Fractional Difference with Quaternionic Fractional Order and Applications to Fractional Difference Equation

open access: yesAnalele Stiintifice ale Universitatii Ovidius Constanta: Seria Matematica
In this paper, we introduce the basic notions of the fractional summation, difference and q-difference with the quaternionic fractional order for the quaternion-valued functions and establish some of their basic properties.

Quantum Money from Quaternion Algebras [PDF]

open access: yes, 2022
We propose a new idea for public key quantum money. In the abstract sense, our bills are encoded as a joint eigenstate of a fixed system of commuting unitary operators. We perform some basic analysis of this black box system and show that it is resistant

Plant Secondary Metabolites as Anticancer Agents: Successes in Clinical Trials and Therapeutic Application

open access: yesInternational Journal of Molecular Sciences, 2018
Cancer is a multistage process resulting in an uncontrolled and abrupt division of cells and is one of the leading causes of mortality. The cases reported and the predictions for the near future are unthinkable.

Secondary building units as the turning point in the development of the reticular chemistry of MOFs

open access: yesScience Advances, 2018
The SBU approach facilitated the development of permanently porous MOFs with unique properties, chemistry, and applications. The secondary building unit (SBU) approach was a turning point in the discovery of permanently porous metal-organic frameworks ...

Plant Secondary Metabolites as Defenses, Regulators, and Primary Metabolites: The Blurred Functional Trichotomy1[OPEN]

open access: yesPlant Physiology, 2020
Plant chemicals known to mediate plant environment interactions also function as hormone-like regulators and precursors of primary metabolites. The plant kingdom produces hundreds of thousands of low molecular weight organic compounds.
