DataEX‐Sc: A Specialized Parsing Model for Materials Science Scatter Plots Based on Multi‐Strategy Fusion and Bidirectional Optimization

open access: yesMaterials Genome Engineering Advances, EarlyView.
We present DataEX_Sc, a specialized model for parsing scatter plots, to make valuable contributions to data‐driven materials science. It improves accuracy by 0.23 (absolute F1 gain when relative error threshold = 0.02) over full‐automatic tools and boosts efficiency by 80% compared with semi‐automated tools.

Dynamic Cell Division for Interference Management in Satellite Direct‐to‐Cell Systems

open access: yesInternational Journal of Satellite Communications and Networking, EarlyView.
ABSTRACT Direct‐to‐cell (D2C) connectivity enables future non‐terrestrial networks to provide service directly to standard terrestrial user equipment (UE) when terrestrial networks (TN) are unavailable. In this work, the satellite system is considered as a secondary network that supplements existing TN coverage while minimizing interference to the ...

Does Economic Growth Drive Equitable Water and Sanitation Access? Assessing Inequality Reduction Across 64 Nations

open access: yesSustainable Development, EarlyView.
ABSTRACT This article examines whether economic growth reduces inequalities in access to water and sanitation across 64 countries over an average period of 13.5 years. Drawing on disaggregated data by income quintiles and rural–urban location, and employing ordinary least squares (OLS), two‐stage least squares (2SLS), and Seemingly Unrelated Regression

Deploying Soft Operations Research Techniques in Hybrid Modelling: The Role of Qualitative System Dynamics in Sustainability Analysis

open access: yesSystems Research and Behavioral Science, EarlyView.
ABSTRACT Organisations increasingly need modelling approaches that can support sustainable development decisions across economic, environmental and social dimensions. The triple bottom line (TBL) perspective provides a useful basis for such analysis, but it also introduces modelling challenges because the relevant dimensions are often interdependent ...

Approximating multiple class queueing models with loss models [PDF]

open access: yes
Multiple class queueing models arise in situations where some flexibility is sought through pooling of demands for different services. Earlier research has shown that most of the benefits of flexibility can be obtained with only a small proportion of ...

“Who Is Watching me?”: Recovering the Grammar of Stigma in Interaction

open access: yesSymbolic Interaction, EarlyView.
This article offers a praxeological respecification of stigma. I argue that the term “stigma” is a category term and glossing device, used to gather together and stand in for a diverse range of interactional experiences, including, but not limited to, degradation, discrediting, discrimination, marginalization, and being demeaned.
