An Integrated Methodology for Assessing Wind Power Curtailment Using Anemometric Measurements and Operational Data in the Brazilian Context

open access: yesAtmosphere
The increasing share of wind power generation has intensified the occurrence of curtailment events in power systems worldwide, mainly driven by transmission constraints, operational limitations, and imbalances between generation and demand.

The West African port system: global insertion and regional particularities

open access: yesEchoGéo, 2012
The changes that occur in a port system depend on how it is integrated within the global maritime network and its relationship with local and regional spaces with their specific economic, political and geographical characteristics.

Operation Leyte – operational fires

open access: yesSecurity and Defence Quarterly, 2018
<i>Operational fires are one of most important functions in a synergy effect with other operational functions that contribute to the achievement of targeted operational goals. The main operational goal of the American takeover of the Philippines was cutting Japan’s supply lines.

On Integral Operators with Operator-Valued Kernels [PDF]

open access: yesJournal of Inequalities and Applications, 2010
Here Lq-Lp boundedness of integral operator with operator-valued kernels is studied and the main result is applied to convolution operators. Using these results Besov space regularity for Fourier multiplier operator is established.

From junk to function — How weak selection in eukaryotes builds new parts and drives genomic complexity

open access: yesFEBS Letters, EarlyView.
How do genomes gain new functional parts? In eukaryotes, which tend to evolve under weak selection, much of the genome is junk. Palazzo and Qiu borrow the logic of Markov chains to show how non‐functional DNA becomes functional through the appearance of intermediate states, which arise due to epistasis, buffering, and biochemical messiness, allowing ...

To operate or not to operate, that is the question

open access: yesBone & Joint Research, 2016
To operate or not to operate, that is the question. In the case of a displaced diaphyseal fracture of the femur, this question is not a challenge. We do not need a randomised controlled trial to determine if intramedullary nailing of a fracture of the femur is more effective, for any outcome ...

The Shewanella oneidensis Fic enzyme SoFic targets the switch‐I region of EF‐Tu for AMPylation

open access: yesFEBS Letters, EarlyView.
Fic enzymes mediate diverse post‐translational modifications across all domains of life, including AMPylation. Prokaryotic EF‐Tu can be AMPylated and deAMPylated by the conserved Fic enzyme SoFic. Structural and biochemical approaches were used to characterize the effect of AMPylation on EF‐Tu, SoFic's enzymatic activities, and the enzyme‐target ...

THE HEAT OPERATOR OF A TRANSVERSALLY ELLIPTIC OPERATOR [PDF]

open access: yesJP Journal of Geometry and Topology, 2017
Let $G$ be a connected compact Lie group. We study the heat operator of a $G$-transversally elliptic operator. After we review the spectral properties of a $G$-transversally elliptic operator, we define the character, that is a distribution on $G$ generalizing the trace of the heat operator to the $G$-equivariant case.

L‐aspartate oxidase provides new insights into fumarate reduction in anaerobic darkness in Synechocystis sp. PCC6803

open access: yesFEBS Letters, EarlyView.
Synechocystis strains deficient in succinate dehydrogenase (SDH) secrete more succinate than the WT under dark anaerobic conditions, supporting that SDH then primarily acts as SDH, not as a fumarate reductase. L‐aspartate oxidase (Laspo) from Synechocystis is functional under anaerobic conditions, reducing fumarate to succinate.

Photovoltaic penetration potential in the Greek island of Ikaria

open access: yesSolar Compass
The operation of Distribution Networks (DNs) has been affected by the ongoing energy transition, gradually incorporating more Distributed Energy Resources (DERs), mainly Renewable Energy Sources (RES), as well as Energy Storage Systems (ESS) sustainably ...
