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

Spatial Spillovers and Green Growth: Decoding Environment‐Adjusted Agricultural Productivity Dynamics

Agricultural Economics, Volume 57, Issue 5, September 2026.
ABSTRACT This paper develops a novel production function framework that accounts for spatial spillovers in environment‐adjusted agricultural productivity and its components, namely technical change, scale efficiency change and environmental efficiency change, in a single‐stage setting, with greenhouse gas (GHG) emissions incorporated as an undesirable ...

Resolving Micrometre‐Scale Zircon Growth in Silicic Systems by 7 μm LA‐MC‐ICP‐MS U‐Pb Dating: Linking Petrology and Geochronology in Silicic Volcanic and Granitic Rocks from Victoria, Australia

Geostandards and Geoanalytical Research, Volume 50, Issue 3, Page 625-647, September 2026.
Key Points 7 μm spot‐diameter LA‐MC‐ICP‐MS analyses yield accurate zircon U‐Pb ages. 1013 Ω amplifier resistors improve low‐signal Pb measurements. Saturn correction protocols minimise down‐hole fractionation effects. We present a systematic evaluation of high spatial‐resolution zircon U‐Pb dating using a Thermo Scientific Neoma multi‐collector ICP‐MS ...

Long‐term effects of clear‐cutting forestry on ectomycorrhizal fungi in boreal forest

New Phytologist, Volume 251, Issue 5, Page 2818-2831, September 2026.
Summary Clear‐cutting is detrimental to ectomycorrhizal fungi in a short time perspective, but long‐term effects on species richness and community composition are uncertain. To evaluate ecological sustainability of rotation forestry, we examined to what extent communities similar to those in old forests develop within the time frame of a rotation ...

Reproducible Ozaki‐Based Matrix Multiplication on Photonic Matrix Processors With Algorithm‐Based Fault Tolerance

Concurrency and Computation: Practice and Experience, Volume 38, Issue 16, August 2026.
ABSTRACT Photonic matrix processors are attracting attention in applications such as AI inference due to their low‐power and low‐latency properties. However, their applicability has been largely limited to low‐precision computation due to inherent stochastic analog noise and device non‐idealities.

Estivation Strategies of Invasive Snail Pomacea canaliculata in Paddy Fields: Roles of Gut Microbiota and Digestive Gland Metabolism

Ecology and Evolution, Volume 16, Issue 8, August 2026.
During the summer fallow period, Pomacea canaliculata enters estivation under high temperature and drought stress yet maintains a survival rate exceeding 92%. Restructuring of the gut microbiota and metabolic adaptations in the liver, particularly the stability of fatty acid profiles, underpin its strong estivation tolerance.

Decentralized Federated Learning for Wind Turbine Bearing Prognostics Under Data Scarcity and Statistical Heterogeneity

Energy Science &Engineering, Volume 14, Issue 8, Page 3674-3696, August 2026.
This paper proposes a decentralized peer‐to‐peer federated learning framework for wind turbine bearing remaining useful life prediction, introducing a virtual client paradigm in which statistical health indicators serve as independent feature‐level clients—enabling privacy‐preserving collaborative prognostics from a single physical asset under ...
