Advances in causal discovery methods for ecological time series

Biological Reviews, EarlyView.
ABSTRACT Recent advances in data collection technologies (e.g. automated sensor networks, satellite remote sensing, and high‐throughput sequencing) have greatly expanded the availability of ecological time series, enabling new opportunities for causal analyses in dynamic ecosystems.

Decarbonization in Financial Turbulent Times: Global Value Chains and Regulatory Framework

Business Strategy and the Environment, EarlyView.
ABSTRACT This study examines how participation in global value chains (GVCs) influences carbon emissions amid financial turbulence, with attention to cross‐country heterogeneity and distributional dynamics. Although existing research has explored trade–environment linkages, limited attention has been given to how GVC integration interacts with ...

Pathways to Carbon Neutrality: The Role of Environmental Governance, Environmental Technology, Renewable Energy Transition, and Economic Policy Uncertainty in Africa

Business Strategy and the Environment, EarlyView.
ABSTRACT As climate change and environmental deterioration continue to escalate due to substantial CO2 emissions, nations worldwide are implementing approaches to alleviate CO2 emissions and accomplish carbon neutrality (CNE) goals. The current study examined CNE objectives for five selected nations in Africa, spanning from 1990 to 2022.

First-passage time: a conception leading to superstatistics

Condensed Matter Physics, 2006
To describe the nonequilibrium states of a system we introduce a new thermodynamic parameter -- the lifetime (the first passage time) of a system. The statistical distributions that can be obtained out of the mesoscopic description characterizing the ...

Integrating ESG Into Business Strategy: Evidence on Firm Performance From European High‐Materiality Industries

Business Strategy and the Environment, EarlyView.
ABSTRACT The integration of environmental, social, and governance (ESG) factors into corporate business strategy has become progressively important, particularly for firms operating in high‐materiality industries where nonfinancial risks are more pronounced. This study examines the association between ESG performance and firm performance among European

Optimization of 3D‐Printed Structured Packings—Current State and Future Developments

Chemie Ingenieur Technik, EarlyView.
This paper gives an overview about structured packing development for distillation, surveying heuristic development cycles, computational fluid dynamics simulations, and additive manufacturing techniques. The emerging application of shape optimization to improve packings is emphasized, and its benefits, impact, and limitations are discussed.

Stochastic resetting and large deviations

SciPost Physics Lecture Notes
Stochastic resetting has been a subject of considerable interest within statistical physics, both as means of improving completion times of complex processes such as searches and as a paradigm for generating nonequilibrium stationary states.

Hidden Markov graphical models with state‐dependent generalized hyperbolic distributions

Canadian Journal of Statistics, EarlyView.
Abstract In this article, we develop a novel hidden Markov graphical model to investigate time‐varying interconnectedness between different financial markets. To identify conditional correlation structures under varying market conditions and accommodate shape features embedded in financial time series, we rely upon the generalized hyperbolic family of ...

Power spectral density and the brain

Canadian Journal of Statistics, EarlyView.
Abstract Time series from M/EEG (magneto/electroencephalography) and ECoG (electrocorticography) recordings are common sources of information about brain function. The power spectral density (PSD) preserves much of this information, up to second order. In the current decade, a burst of brain diagnostics using the slope of log(PSD) has appeared.

The SIR Model in a Moving Population: Propagation of Infection and Herd Immunity

Communications on Pure and Applied Mathematics, EarlyView.
ABSTRACT In a collection of particles performing independent random walks on Zd$\mathbb {Z}^d$ we study the spread of an infection with SIR dynamics. Susceptible particles become infected when they meet an infected particle. Infected particles heal and are removed at rate ν$\nu$.
