Forecasting Volatility of Commodity, Currency, and Stock Markets: Evidence From Markov‐Switching Multifractal Models

Journal of Forecasting, Volume 45, Issue 6, Page 2905-2941, September 2026.
ABSTRACT This paper adopts a bivariate Markov‐switching multifractal (BMSM) model to reexamine comovement in SV between commodity, foreign exchange (FX), and stock markets. After the 2007–2008 global financial crisis understanding volatility linkages and the correlation structure between these markets becomes very important for risk analysts, portfolio

Structure Formation in Dairy Cheese and Plant‐Based Cheese Analogues: A Review

Sustainable Food Proteins, Volume 4, Issue 3, September 2026.
In this review, structure formation in dairy cheese and plant‐based cheese analogues is analyzed following a multi‐length scale perspective. Particular emphasis is placed on the distinction between bottom‐up assembly, characteristic of natural dairy cheese, and top‐down structuring, typical of processed cheese and cheese analogues.

A Systematic Review of Urban Form: Knowledge and Opportunities

Earth's Future, Volume 14, Issue 9, September 2026.
Abstract Understanding global research trajectories in urban form is critical for sustainable urbanization, yet a comprehensive synthesis is lacking. Evaluating 6,147 publications from Web of Science and Scopus (1999–2024) using bibliometric methods, this study maps the evolution, core themes, and geographical distribution of the field.
