A Deep Learning Framework for Forecasting Medium‐Term Covariance in Multiasset Portfolios

Journal of Forecasting, Volume 45, Issue 4, Page 1797-1828, July 2026.
ABSTRACT Forecasting the covariance matrix of asset returns is central to portfolio construction, risk management, and asset pricing. However, most existing models struggle at medium‐term horizons, several weeks to months, where shifting market regimes and slower dynamics prevail.

Forecasting House Prices: The Role of Market Interconnectedness

Journal of Forecasting, Volume 45, Issue 4, Page 1847-1877, July 2026.
ABSTRACT While the existing research uncovers interconnections between various housing markets, it largely ignores the question of whether such linkages can improve house price predictions. To address this issue, we proceed in two steps. First, we forecast disaggregated house price growth rates from Australia and China to determine whether ...

Decoding the Structural Complexity of Fungal α‐ and β‐Glucan Matrix via Statistical Analysis of Solid‐State NMR Chemical Shifts

Israel Journal of Chemistry, Volume 66, Issue 4, July 2026.
Solid‐state NMR combined with principal component analysis enables quantitative classification of fungal α‐ and β‐glucan architectures in intact cell walls, revealing conserved triple‐helical β‐1,3‐glucan conformations across species and predominantly bundled‐sheet α‐1,3‐glucan assemblies with condition‐dependent polymorphism. Statistical clustering of

Evaluation of Adaptive, Productive and Reproductive Performance of Boran Dairy Breed in the Lowland Agro‐Ecology of Kaffa Zone, South‐Western Ethiopia

Veterinary Medicine and Science, Volume 12, Issue 4, July 2026.
Boran dairy cattle demonstrated acceptable productive, reproductive and adaptive performance under lowland conditions of south‐western Ethiopia. Significant effects of parity and lactation stage were observed on milk yield and blood parameters, while physiological values remained within normal ranges, confirming good adaptation and potential for ...

Incorporating Spatial Information in Entropy‐Weighted Composite Indicators: An Application to Education and Training in Italy

Geographical Analysis, Volume 58, Issue 3, July 2026.
ABSTRACT This study introduces a novel methodology in which a composite indicator derived using the Entropy Weight Method is decomposed into a location‐specific component and a spatial component. Although EWM is widely recognized for its robustness in constructing data‐driven composite indicators, standard applications typically overlook spatial ...
