Toward Improving the Efficiency of Software Development Effort Estimation via Clustering Analysis

open access: yesIEEE Access, 2022
Introduction: The precise estimation of software effort is a significant difficulty that project managers encounter during software development. Inaccurate forecasting leads to either overestimating or underestimating software effort, which can be ...

Tree species diversity increases soil microbial carbon use efficiency in a subtropical forest

open access: yesGlobal Change Biology, Volume 29, Issue 24, Page 7131-7144, December 2023., 2023
We examined how soil microbial CUE is influenced by plant and soil microbial community traits, by studying a natural gradient of plant species diversity in a subtropical forest. Our results showed that high microbial CUE was associated with soil properties correlated with increased tree species diversity: higher substrate availability (simple SOM ...

Toward the sustainability state? Conceptualizing national sustainability institutions and their impact on policy‐making

open access: yesEnvironmental Policy and Governance, Volume 33, Issue 3, Page 313-324, June 2023., 2023
Abstract The achievement of global sustainability and climate objectives rests on their incorporation into policy‐making at the level of nation‐states. Against this background, governments around the world have created various specialized sustainability institutions—councils, committees, ombudspersons, among others—in order to promote these agendas and

Transient stability analysis of the standalone solar‐storage AC supply system based on grid‐forming and grid‐following converters during sudden load variation

open access: yesIET Renewable Power Generation, Volume 17, Issue 5, Page 1286-1302, 6 April 2023., 2023
The incompatibility of the dynamic performance between the GFM and GFL converters due to different control schemes may introduce the transient instability risk to the solar‐storage supply system. To address this issue, it is extremely necessary to perform transient stability analysis and stability‐enhanced control for the standalone solar‐storage AC ...

Gastrointestinal Effects on the Antioxidant and Immunomodulatory Properties of South African Fynbos Honey

open access: yesInternational Journal of Food Science, Volume 2023, Issue 1, 2023., 2023
The Fynbos biome, Western Cape Province, South Africa, produces a unique honey from Apis mellifera capensis. The bioactivity of Fynbos (FB1‐FB6) honeys and Manuka, unique manuka factor 15+ (MAN UMF15+) honey subjected to simulated in vitro digestion, was compared. The effect of each phase of digestion on the antioxidant properties and nitric oxide‐ (NO‐

Antrodia cinnamomea Extract Attenuates Cisplatin‐Induced Muscle Atrophy, Apoptosis, and Cell Growth Suppression

open access: yesJournal of Food Biochemistry, Volume 2023, Issue 1, 2023., 2023
Antrodia cinnamomea (AC), a potential medicinal fungus which possesses anti‐inflammatory and anticancer activities, has been previously reported to be able to ameliorate muscle wasting in cisplatin‐treated lung tumor‐bearing mice via AC extract. However, whether AC extract modulates muscle cell differentiation, apoptosis, and cell cycle progression ...

A new method for operating point free power system transient stability situational awareness based on single machine equivalent approach

open access: yesEngineering Reports, Volume 4, Issue 11, November 2022., 2022
This article proposed a new offline–online method for first swing stability situational awareness. The method is based on a single machine equivalent approach. IEEE 9 bus and 39 bus test systems are used to illustrate the proposed method. The proposed method is very much helpful in finding critically stable cases with respect to first swing stability ...

Transient stability emergency control for AC/DC grids considering successive commutation failures

open access: yesIET Generation, Transmission &Distribution, Volume 16, Issue 7, Page 1319-1333, April 2022., 2022
Abstract The prevalence of Line‐Commutated Converter (LCC) HVDC makes the coupling and interaction phenomenon between AC system and DC system of particular complicated. There are significant challenges to determine control strategy using state‐of‐the‐art approaches especially when discrete events (e.g.

Nonmarket Valuation in the Environmental Protection Agency's Regulatory Process

open access: yesApplied Economic Perspectives and Policy, Volume 43, Issue 3, Page 952-969, September 2021., 2021
Abstract This paper reviews the use of nonmarket valuation in environmental policy at the US Environmental Protection Agency (EPA). We examine trends in the literature over the last forty‐five years and compare those trends to how often nonmarket benefits are monetized and which methods are used in 49 recent EPA Regulatory Impact Analyses.
