Developments and Prospects of Voltage Source Converter‐High‐Voltage Direct Current Transmission Technology

open access: yesHigh Voltage, EarlyView.
ABSTRACT Voltage source converter‐high‐voltage direct current (VSC‐HVDC) transmission is a key technology for renewable‐energy integration, regional grid interconnection and passive‐network power supply. This review summarises the development history of VSC‐HVDC, the evolution of converter topologies, its technical advantages and representative ...

Embedding Optimization of Layouts via Distortion Minimization

open access: yesComputer Graphics Forum, EarlyView.
Abstract Given an embedding of a layout in the surface of a target mesh, we consider the problem of optimizing the embedding geometrically. Layout embeddings partition the surface into multiple disk‐like patches, making them particularly useful for parametrization and remeshing tasks, such as quad‐remeshing, since these problems can then be solved on ...

Persistent in vitro nociceptor hyperexcitability and axonal retraction produced by repeated paclitaxel doses

open access: yesThe FEBS Journal, EarlyView.
Repeated paclitaxel exposure causes long‐lasting nociceptor hyperexcitability and axonal retraction in adult sensory neurons. Using a long‐term primary nociceptor culture, we show that hyperexcitability is mediated by sequential upregulation of NaV1.8, TRPV1, TRPA1, and TRPM8 channels.

Small-signal stability analysis of multi-terminal VSC-based dc transmission systems

open access: yes, 2012
A model suitable for small-signal stability analysis and control design of multi-terminal dc networks is presented. A generic test network that combines conventional synchronous and offshore wind generation connected to shore via a dc network is used to ...

Analysis of cation‐π interactions using quantum chemistry and statistical analysis of high‐resolution protein structures

open access: yesThe FEBS Journal, EarlyView.
Shown is a typical detail of a high‐resolution crystal structure (PDB ID 1B5E, chain A) showing the nearness of a phenylalanine residue, Phe24, and a lysine residue, Lys32, that are not engaged in the proposed cation–π interaction. The study statistically examines charged residues near phenylalanine's aromatic ring, supported by quantum chemical ...

Floral Trait Influence on the Foraging Decisions of a Fly Pollinator

open access: yesJournal of Applied Entomology, EarlyView.
ABSTRACT Flies foraging for floral resources provide important ecosystem services through the pollination of myriad angiosperms, including many crop species. However, the specific floral cues used by fly pollinators to locate and discriminate among floral rewards and the preferences they may have for specific cues remain poorly understood.
