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 ...

A Comparative Study of NOx Emission Characteristics in a Fuel Staging and Air Staging Combustor Fueled with Partially Cracked Ammonia

open access: yesEnergies, 2022
Recently, ammonia is emerging as a potential source of energy in power generation and industrial sectors. One of the main concerns with ammonia combustion is the large amount of NO emission.

Does energy efficiency affect ambient PM2.5? The moderating role of energy investment [PDF]

open access: yesFrontiers in Environmental Science. 2021, 9, 2021
The difficulty of balance between environment and energy consumption makes countries and enterprises face a dilemma, and improving energy efficiency has become one of the ways to solve this dilemma. Based on data of 158 countries from 1980 to 2018, the dynamic TFP of different countries is calculated by means of the Super-SBM-GML model.

On the Potential of District-Scale Life Cycle Assessments of Buildings

open access: yesEnergies, 2023
Climate neutrality goals in the building sector require a large-scale estimation of environmental impacts for various stakeholders. Life Cycle Assessment (LCA) is a viable method for this purpose.

Efficiency statistics of a quantum Otto cycle [PDF]

open access: yes, 2021
The stochastic efficiency [G. Verley et al., Nat. Commun. 5, 4721 (2014)] was introduced to evaluate the performance of energy-conversion machines in micro-scale. However, such an efficiency generally diverges when no heat is absorbed while work is produced in a thermodynamic cycle.

Increasing the efficiency of study selection for systematic reviews using prioritization tools and a single-screening approach

open access: yesSystematic Reviews, 2023
Background Systematic literature screening is a key component in systematic reviews. However, this approach is resource intensive as generally two persons independently of each other (double screening) screen a vast number of search results.

Efficient formulas for efficiency correction of cumulants [PDF]

open access: yesPhys. Rev. C 93, 044911 (2016), 2016
We derive formulas which connect cumulants of particle numbers observed with efficiency losses with the original ones based on the binomial model. These formulas can describe the case with multiple efficiencies in a compact form. Compared with the presently suggested ones based on factorial moments, these formulas would drastically reduce the numerical
