Do Time-Varying Covariances, Volatility Comovement and Spillover Matter? [PDF]

Financial markets and their respective assets are so intertwined; analyzing any single market in isolation ignores important information. We investigate whether time varying volatility comovement and spillover impact the true variance-covariance matrix ...

Thermally Regulated Methanol Selectivity in Photo‐Thermo Methane Oxidation Through Interfacial Methyl Transfer

Advanced Science, EarlyView.
Photo‐thermo cascade catalysis enables highly selective methane‐to‐methanol conversion over Au‐ZnO, achieving a CH3OH production rate of ∼800 µmol h−1 with 86% selectivity. Thermal activation gates the transfer of methane‐derived methyl intermediates from ZnO to Au, thereby redirecting the reaction pathway toward methanol formation. ABSTRACT The direct

Pathogen spillover driven by rapid changes in bat ecology

, 2022
During recent decades, pathogens that originated in bats have become an increasing public health concern. A major challenge is to identify how those pathogens spill over into human populations to generate a pandemic threat1.

The Potential of Zero Charge: An Interfacial Descriptor Governing Hydrogen Evolution Reaction on Bulk Metal Electrodes

Advanced Science, EarlyView.
This work establishes a dual‐descriptor framework incorporating hydrogen adsorption free energy and potential of zero charge, constructing a corrected 3D HER volcano plot. It reveals that surface charge and interfacial proton concentration jointly govern activity, beyond conventional 2D thermodynamic scaling relations. ABSTRACT While the Sabatier‐based

A comparison of Spillover Effects before, during and after the 2008 Financial Crisis [PDF]

This paper applies graphical modelling to the S&P 500, Nikkei 225 and FTSE 100 stock market indices to trace the spillover of returns and volatility between these three major world stock market indices before, during and after the 2008 financial crisis ...

Overcoming the *H‐NOx Coupling Bottleneck via Palladium‐Enabled Relay Catalysis on CuCo2O4 Toward Ampere‐Level Nitrate‐to‐Ammonia

Advanced Science, EarlyView.
Pd‐doped hollow spiny CuCo2O4 microspheres deliver ampere‐level electrocatalytic nitrate to ammonia. Cu and Co sites undergo relay catalysis for sequential nitrate reduction, while Pd accelerates water dissociation to supply abundant active hydrogen (*H).

Spillover Beliefs between Health and Pro-Environmental Behaviours

European Journal of Health Communication (EJHC)
Health and environment are closely related. These interrelationships are conceptualised within the framing of planetary health. Targeting health and pro-environmental behaviours (PEB) together is of growing interest.

Rabies in Foxes, Aegean Region, Turkey

Emerging Infectious Diseases, 2009
At the end of the 1990s in the Aegean region of Turkey, rabies rapidly spread among foxes. This spread likely resulted from spillover infection from dogs and led to increased rabies cases among cattle. To control this outbreak, oral rabies vaccination of
