International Journal for Numerical Methods in Fluids, EarlyView.A three‐dimensional fluid‐structure interaction (FSI) framework is developed using the geometric volume‐of‐fluid (VOF) interface capturing method and applied to assess largescale turbulent FSI interactions. The monolithic FSI framework is extensively validated, and despite the discontinuities across the interface, the FSI framework delivers stable and ...

A New Implementation of Network GARCH Model for Stock Volatility and Co‐Volatility Forecasting
Journal of Forecasting, EarlyView.ABSTRACT Volatility clustering and spillovers are key features of financial time series with many cross‐sectional assets. While network analysis links similar or correlated stocks and helps trace volatility spillovers, contemporary multivariate ARCH‐GARCH formulations struggle to represent structured network dependence and remain parsimonious.

Interpolatory product quadratures for Cauchy principal value integrals with Freud weights [PDF]
, 1997 We prove convergence results and error estimates for interpolatory product quadrature formulas for Cauchy principal value integrals on the real line with Freud-type weight functions.

The Trapezoidal Rule for Computing Cauchy Principal Value Integral on Circle [PDF]
, 2020 The composite trapezoidal rule for the computation of Cauchy principal value integral with the singular kernel cot(( − )/2) is discussed. Our study is based on the investigation of the pointwise superconvergence phenomenon; that is, when the singular ...

Journal of Adolescence, EarlyView.ABSTRACT Introduction Socioeconomic disparities in academic achievement are well‐documented in France and emerge early in schooling. Yet, a subset of students from socioeconomically disadvantaged backgrounds attains high academic performance, challenging deterministic accounts of educational inequality.

Hitting Times in the Binomial Random Graph
Journal of Graph Theory, EarlyView.ABSTRACT Fix k ≥ 2 $k\ge 2$, choose log n n ( k − 1 ) ∕ k ≤ p ≤ 1 − Ω ( log 4 n n ) $\frac{\mathrm{log}n}{{n}^{(k-1)\unicode{x02215}k}}\le p\le 1-{\rm{\Omega }}(\frac{{\mathrm{log}}^{4}n}{n})$, and consider G ~ G ( n , p ) $G\unicode{x0007E}G(n,p)$. For any pair of vertices v , w ∈ V ( G ) $v,w\in V(G)$, we give a simple and precise formula for the ...

The numerical evaluation of cauchy principal values of integrals by Romberg integration
Numerische Mathematik, 1973 The problem considered is that of evaluating numerically an integral of the form[Figure not available: see fulltext.] where the integrand has one or more simple poles in the interval (O,p). Modified forms of the trapezoidal and mid-ordinate rules, taking account of the singularities, are obtained; it is then shown that the resulting approximations can ...
