River Research and Applications, EarlyView.ABSTRACT Accurately predicting open‐channel flow under complex conditions remains a challenge. This study introduces a novel synergetic self‐adaptive data assimilation (DA) framework, using a proportional‐integral‐derivative (PID) controller to dynamically calibrate the bed roughness parameter ks in a shallow‐water equation model (via the momentum ...

, 2020 This book gives an introduction to fundamental aspects of generalized Riemannian, complex, and K hler geometry. This leads to an extension of the classical Einstein-Hilbert action, which yields natural extensions of Einstein and Calabi-Yau structures as `canonical metrics' in generalized Riemannian and complex geometry.

Metaverse and Artificial Intelligence as Web 4.0: The Next Generation of the Internet
Systems Research and Behavioral Science, EarlyView.ABSTRACT This study utilizes systems thinking to explore and entwine an evolving metaverse scholarship to a relatively underexplored phenomenon of Web 4.0. We adopt a soft systems thinking framework to guide the interpretation of complex and evolving metaverse scholarship, using bibliometric mapping of 5587 publications sourced from Scopus.

Ricci Flow and Volume Renormalizability [PDF]
Symmetry, Integrability and Geometry: Methods and Applications, 2019 With respect to any special boundary defining function, a conformally compact asymptotically hyperbolic metric has an asymptotic expansion near its conformal infinity. If this expansion is even to a certain order and satisfies one extra condition, then it is possible to define its renormalized volume and show that it is independent of choices that ...

MathematicsIn this paper, we study the topology of steady gradient Ricci solitons with nonnegative sectional curvature. We apply a characterization theorem for the fundamental group of a positively curved steady gradient Ricci soliton that admits a critical point ...

Australian Journal of Agricultural and Resource Economics, EarlyView.ABSTRACT The purpose of this paper is to discuss the micro‐ and macro‐outcomes for the standard neoclassical carbon tax (whose burden falls on the producers) versus the implication of a budget neutral, performance‐based EU Common Agricultural Policy (CAP) focusing on non‐CO2 emission (N2O and CH4, measured in CO2eq) reduction, especially in the ...

Allergy, EarlyView.The threshold of reactivity during fresh milk challenges was 70% lower than that of baked milk challenges, reflecting the higher allergenicity of fresh milk. BAT was the only biomarker statistically significantly different between severity and threshold groups, for baked milk and fresh milk allergies, respectively.
