Climate Change Laws and European Stock Markets: An Event Analysis
International Journal of Finance &Economics, EarlyView.ABSTRACT Under the context of the climate change we assess the impact of EU's legislative initiative on European stock markets. Specifically, we focus on its impact on energy and Environmental Social Governance (ESG) sectors for equity returns and volatility for a representative basket of EU countries (participating also in Eurozone) as well as ...

AlgorithmsIn this article, a particular approach to deriving recursive state estimators for linear state space models is generalised, namely the weighted least-squares approach introduced by Duncan and Horn in 1972, for the case of the two noise processes arising ...

Ground truth applications to orbit refinements [PDF]
A weighted least-squares recursive estimator program is reported for simulating spacecraft orbital position by analyzing earth and sun sensor data. The program uses constant time adjustment for a set of ephemeris data to eliminate intrack error and to ...

InfoMat, EarlyView.To address the limitations of conventional trial‐and‐error approaches, perovskite solar cell research is shifting toward a new paradigm that utilizes datasets and AI. This review examines the fundamental elements of data‐driven and AI‐integrated research: data platforms, AI methodologies, and self‐driving laboratories, demonstrating how their ...

Interdisciplinary Medicine, EarlyView.This study develops a novel miRNA‐based framework for estimating the time since deposition of semen stains, combining small RNA sequencing with machine learning. Time‐dependent miRNA modules were identified using Mfuzz clustering and WGCNA, followed by a multi‐stage feature selection pipeline that reduced 261 candidate miRNAs to a minimal 7‐miRNA panel.

Asset pricing with adaptive learning [PDF]
We study the extent to which self-referential adaptive learning can explain stylized asset pricing facts in a general equilibrium framework. In particular, we analyze the effects of recursive least squares and constant gain algorithms in a production ...

From Reactive to Proactive Volatility Modeling With Hemisphere Neural Networks
Journal of Applied Econometrics, EarlyView.ABSTRACT We revisit maximum likelihood estimation (MLE) for macroeconomic density forecasting through a novel neural network architecture with dedicated mean and variance hemispheres. Our architecture features several key ingredients making MLE work in this context.

Generalized Stochastic Gradient Learning [PDF]
We study the properties of generalized stochastic gradient (GSG) learning in forward-looking models. We examine how the conditions for stability of standard stochastic gradient (SG) learning both differ from and are related to E-stability, which governs ...

What Explains International Interest Rate Co‐Movement?
Journal of Applied Econometrics, EarlyView.ABSTRACT The international co‐movement of interest rates reflects correlated business‐cycle fluctuations, largely driven by demand shocks. Monetary policy in advanced economies follows domestic mandates—inflation and the output gap—and does not respond to foreign policy shocks.

JCPP Advances, EarlyView.This study found that parent internalising symptoms predicted internalising symptoms in younger children, with no evidence of child‐driven effects. Among adolescents, mental health symptoms showed bidirectional associations with parent internalising symptoms, particularly for externalising symptoms.
