An Examination of the Multiphase Darcy Model of Fluid Displacement in Porous Media Examen du modèle polyphasique de Darcy de déplacement de fluides en milieu poreux

Wright R. J., Dawe R. A. • Oil & Gas Science and Technology (2006)

The multiphase Darcy model used to represent two-phase immiscible displacement flow within porous media is critically examined, and the principle assumptions and limitations discussed. We identify some of the main problems which require bet...

Analytic NNLO QCD corrections to top quark pair production in electron-positron collisions

Long-Bin Chen, Jian Wang, Yefan Wang • Journal of High Energy Physics (2024)

Abstract We present the analytic total cross section of top quark pair production in electron-positron annihilation at next-to-next-to-leading order (NNLO) in Quantum Chromodynamics (QCD). By utilizing the optical theorem, the NNLO correcti...

Mechanism for rapid growth of organic–inorganic halide perovskite crystals

Pabitra K. Nayak, David T. Moore, Bernard Wenger, Simantini Nayak et al. • Nature Communications (2016)

Single crystals of lead halide perovskites exhibit good optoelectronic properties. Here, the authors study and deduce the mechanism for crystallisation and show how controlling dissolution of colloids through varying the acidity and tempera...

Enhanced conformal BMS3 symmetries

Oscar Fuentealba, Iva Lovrekovic, David Tempo, Ricardo Troncoso • Journal of High Energy Physics (2025)

Abstract An enhanced version of the conformal BMS3 algebra is presented. It is shown to emerge from the asymptotic structure of an extension of conformal gravity in 3D by Pope and Townsend that consistently accommodates an additional spin-2...

Phosphopeptide binding to the N-SH2 domain of tyrosine phosphatase SHP2 correlates with the unzipping of its central β-sheet

Michelangelo Marasco, John Kirkpatrick, Teresa Carlomagno, Jochen S. Hub et al. • Computational and Structural Biotechnology Journal (2024)

SHP2 is a tyrosine phosphatase that plays a regulatory role in multiple intracellular signaling cascades and is known to be oncogenic in certain contexts. In the absence of effectors, SHP2 adopts an autoinhibited conformation with its N-SH2...

Fitness-based models and pairwise comparison models of evolutionary games are typically different—even in unstructured populations

Bin Wu, Benedikt Bauer, Tobias Galla, Arne Traulsen • New Journal of Physics (2015)

The modeling of evolutionary game dynamics in finite populations requires microscopic processes that determine how strategies spread. The exact details of these processes are often chosen without much further consideration. Different types ...
