A Modular multilevel converter with hybrid redundant strategy for HVDC system

Energy Reports, 2021
As a typical voltage source converter topology, Modular multilevel converter (MMC) widespread used in high voltage direct current (MMC-HVDC) power systems due to its modularization, low harmonic, easy expansion, and high efficiency.

Krüppel‐Like Factors Orchestrate Endothelial Gene Expression Through Redundant and Non‐Redundant Enhancer Networks

Journal of the American Heart Association: Cardiovascular and Cerebrovascular Disease, 2023
Background Proper function of endothelial cells is critical for vascular integrity and organismal survival. Studies over the past 2 decades have identified 2 members of the KLF (Krüppel‐like factor) family of proteins, KLF2 and KLF4, as nodal regulators ...

How redundant are redundant color adjectives? An efficiency-based analysis of color overspecification

Frontiers in Psychology, 2016
Color adjectives tend to be used redundantly in referential communication. I propose that redundant color adjectives are often intended to exploit a color contrast in the visual context and hence facilitate object identification, despite not being ...

Redundant Arrays of IDE Drives [PDF]

, 2001
The next generation of high-energy physics experiments is expected to gather prodigious amounts of data. New methods must be developed to handle this data and make analysis at universities possible. We examine some techniques that use recent developments

Compressed Sensing and Redundant Dictionaries [PDF]

, 2006
This article extends the concept of compressed sensing to signals that are not sparse in an orthonormal basis but rather in a redundant dictionary. It is shown that a matrix, which is a composition of a random matrix of certain type and a deterministic ...

EVENODD: An Efficient Scheme for Tolerating Double Disk Failures in RAID Architectures [PDF]

, 1995
We present a novel method, that we call EVENODD, for tolerating up to two disk failures in RAID architectures. EVENODD employs the addition of only two redundant disks and consists of simple exclusive-OR computations.

Why and When Are Evidence‐Based Interventions Adopted in Paediatric Supportive Care? A Qualitative Exploration of the Determinants of Photobiomodulation Implementation

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Background Oral mucositis is a common and debilitating side effect of childhood cancer and stem cell transplant treatments. It affects the quality of life of children and young people (CYP) and places a strain on services. Photobiomodulation is recommended for oral mucositis prevention in international guidance but is poorly implemented in UK ...
