Synchronization frequency analysis and stochastic simulation of multi-site flood flows based on the complicated vine copula structure
Published 2025-01-01“…<p>Accurately modeling and predicting flood flows across multiple sites within a watershed presents significant challenges due to potential issues of insufficient accuracy and excessive computational demands in existing methodologies. In response to these challenges, this study introduces a novel approach centered around the use of vine copula models, termed RDV-Copula (reduced-dimension vine copula construction approach). …”

Patterns of diversity in biomedical coauthorships: An analysis across authors' ethnicity, gender, age, and expertise.
Published 2025-01-01“…However, the association between diversity and impact is moderated by the number of collaborating authors, with larger teams sometimes showing opposite trends due to interactions between the computed diversity indices and team size. Despite this complexity, the practical drivers of scientific impact for an article remain the journal of publication, authors' prior citation rate, and the number of co-authors. …”

Influence of the Methane–Zeolite a Interaction Potential on the Concentration Dependence of Self-Diffusivity
Published 2011-06-01“…Fritzsche and co-workers (1993) have shown that these two potentials lead to two distinctly different energetic barriers for the passage of methane through the eight-ring window in the cation-free form of zeolite A. Here, we compute the variation of the self-diffusivity (D) with loading (c) for these two types of potentials and show that this slight variation in the diameter changes the concentration dependence qualitatively: thus, D decreases monotonically with c for model A, while D increases and goes through a maximum before finally decreasing for model B. …”
