Negative pressure wound therapy in patients with wounds healing by secondary intention: a systematic review and meta-analysis of randomised controlled trials

open access: yesSystematic Reviews, 2020
Background Negative pressure wound therapy (NPWT) is a widely used method of wound treatment. We performed a systematic review of randomised controlled trials (RCTs) comparing the patient-relevant benefits and harms of NPWT with standard wound therapy ...

Efficient Removal Without Efficient Regularity [PDF]

open access: yesCombinatorica, 2019
Obtaining an efficient bound for the triangle removal lemma is one of the most outstanding open problems of extremal combinatorics. Perhaps the main bottleneck for achieving this goal is that triangle-free graphs can be highly unstructured. For example, triangle-free graphs might have only regular partitions (in the sense of Szemer di) of tower-type ...

Efficient compromising [PDF]

open access: yesJournal of Economic Theory, 2009
Two agents must select one of three alternatives. Their ordinal rankings are commonly known and diametrically opposed. Efficiency requires choosing the alternative the agents rank second whenever the weighted sum of their von Neumann Morgenstern utilities is higher than under either agent’s favorite alternative.

Operation strategies of battery energy storage systems for preventive and curative congestion management in transmission grids

open access: yesIET Generation, Transmission & Distribution, 2023
Anticipating and relieving congestions is an ongoing challenge for transmission system operators. Distributed grid‐scale battery energy storage systems enable operators to shift power flows and remedy congestion through virtual power lines and grid ...

Effective study selection using text mining or a single-screening approach: a study protocol

open access: yesSystematic Reviews, 2018
Background Systematic information retrieval generally requires a two-step selection process for studies, which is conducted by two persons independently of one another (double-screening approach). To increase efficiency, two methods seem promising, which

A simulation study to compare different estimation approaches for network meta-analysis and corresponding methods to evaluate the consistency assumption

open access: yesBMC Medical Research Methodology, 2020
Background Network meta-analysis (NMA) is becoming increasingly popular in systematic reviews and health technology assessments. However, there is still ambiguity concerning the properties of the estimation approaches as well as for the methods to ...
