MODELING AND SIMULATION OF VSC-HVDC WITH DYNAMIC PHASORS

open access: yesElectrica, 2008
A novel dynamic phasors method to model voltage sources converter based HVDC (VSC-HVDC) transmission system is proposed in this paper. This approach is based on the time-varying Fourier series coefficients of the system variables, and focused on the ...

Biophysical approaches for studying viral entry

open access: yesFEBS Letters, EarlyView.
Viruses infect all living organisms and have been responsible for major epidemics and pandemics. Their ongoing evolutionary battle with host defenses creates a constant need for improved tools to study viral behavior. Advancing methods to probe viral attachment, fusion, and genome release deepen our understanding of how infections begin and support the

Optimization model for distributed energy trading based on a market value allocation mechanism in the electricity spot market

open access: yesFrontiers in Energy Research
This study proposes a novel distributed energy trading market model with a value distribution mechanism to optimize the allocation and transactions of distributed energy resources (DERs).

A Simple but Powerful Measure of Market Efficiency [PDF]

open access: yesSSRN Electronic Journal, 2018
We construct a simple measure to quantify the level of market efficiency. We apply this measure to investigate the level of market efficiency and analyze its variation over time. The main contribution of the new measure is that it makes it easy to compare market efficiency across assets, time, regions, and data frequencies.

Salmonella lipopolysaccharide‐containing supported lipid bilayers as platforms to study bacteriophage interactions

open access: yesFEBS 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 ...

Quantitative stability analysis of Grid-Following inverter with Grid-Supporting control and stability enhancement method based on Multi-Voltage feedforward

open access: yesInternational Journal of Electrical Power & Energy Systems
Grid-following inverters with grid-supporting control (GFLI-GSC) can provide inertia and voltage support to the grid, but GSC degrades their stability under weak grid.

From mice to humans—divergent strategies for intestinal homeostasis and regeneration

open access: yesFEBS Letters, EarlyView.
Recent advances such as organoid genome editing, xenotransplantation, imaging, and whole‐genome sequencing have enabled direct studies of human intestinal stem cells (ISCs). These studies reveal species‐specific features, including slower ISC proliferation, distinct injury responses, slower somatic mutation accumulation in humans, and an inverse ...

Design and analysis strategies for robust microbiome ageing research

open access: yesFEBS Letters, EarlyView.
The gut microbiome changes with age and associates with age‐related morbidity and mortality, establishing it as a potential biomarker and intervention target for ageing. Realising this potential requires methodological rigour, yet distinguishing biological signals from methodological artefacts remains challenging across cohorts. This review provides an

Power efficient mediaprocessors [PDF]

open access: yesProceedings of the 36th annual ACM/IEEE Design Automation Conference, 1999
We present a framework for rapidly exploring the design space of low power application-specific programmable processors (ASPP), in particular mediaprocessors. We focus on a category of processors that are programmable yet optimized to reduce power consumption for a specific set of applications.

Reconstructing enzyme evolution by protein engineering

open access: yesFEBS Letters, EarlyView.
Natural enzyme evolution can be retraced by protein engineering methods such as directed evolution, rational design, and ancestral sequence reconstruction. These approaches reveal how enzymes emerged from ligand‐binding scaffolds, developed varying substrate preferences, formed oligomeric complexes, adapted to environmental changes, and evolved novel ...
