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

open access: yesJournal of Forecasting, EarlyView.
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.

Characterization of the Antioxidant Peptides Prepared From the Seed Kernel of Xanthoceras sorbifolium Using Enzymatic Hydrolysis: Molecular Docking Analysis and In Vitro Binding Studies

open access: yesFood Safety and Health, EarlyView.
XSPH‐I exhibits excellent cellular antioxidant activity and cell protective effects. Four novel antioxidant peptides were screened from XSPH‐I peptide, and the newly synthetic peptide exhibits excellent antioxidant properties in vitro. ABSTRACT In this study, the antioxidant peptides (XSPH) from Xanthoceras sorbifolium oleifera were extracted and ...

Strain analysis of black‐to‐yellow phase transitions in CsPbI3

open access: yesInfoMat, EarlyView.
All‐inorganic metal‐halide perovskite CsPbI3 shows strong potential for photovoltaic applications. Here strain analysis is used to probe the mechanisms behind the instability of its photoactive black phase. The results indicate that a relatively large positive (e1–e2) strain is the primary driver of the black‐to‐yellow phase transition.

A Consistent Heteroskedasticity‐Robust LM‐Type Specification Test for Semiparametric Models

open access: yesJournal of Applied Econometrics, EarlyView.
ABSTRACT This article develops a heteroskedasticity‐robust Lagrange Multiplier‐type specification test for semiparametric regression models. The test is able to detect a wide class of deviations from the null hypothesis. The test statistic is based on the estimates from the restricted semiparametric model, can be computed in a regression‐based way, and
