Silver‐Modulated Copper Dynamics Under Pulsed Tandem Electrochemical CO2 Reduction
Small, EarlyView.Under pulsed CO2 reduction, Ag does more than provide CO for tandem catalysis. It redirects how Cu dissolves, redeposits, and remains catalytically relevant, generating an Ag‐rich yet Cu‐active working state. Correlative surface and solution analysis reveal that tandem performance emerges from dynamic material redistribution rather than from a static ...

The Continuous Limit of GARCH Processess [PDF]
Contrary to popular belief, the diffusion limit of a GARCH variance process is not a diffusion model unless one makes a very specific assumption that cannot be generalized.

Acta Crystallographica Section C, EarlyView.The solvent‐free structure of the thallium(I) salt of the weakly coordinating anion tetrakis[3,5‐bis(trifluoromethyl)phenyl]borate, Tl[BC32H12F24], exhibits short Tl…F contacts and a supramolecular architecture governed by C—H…F hydrogen bonds and weak F…F and C—F…π interactions.

Merits and drawbacks of variance targeting in GARCH models [PDF]
Variance targeting estimation is a technique used to alleviate the numerical difficulties encountered in the quasi-maximum likelihood (QML) estimation of GARCH models.

Pacific Economic Review, EarlyView.ABSTRACT This study investigates the impact of China's recent real estate crisis, stemming from Evergrande's struggles, on the return and risk profiles of US‐listed exchange traded funds (ETFs) tracking Chinese stock market indexes. Analysing 26 funds from February 2, 2018 to December 31, 2024, we first employ a VAR model to assess contagion and ...

Asia‐Pacific Economic History Review, Volume 65, Issue 1, Page 131-159, March 2025.Abstract This study examines the adaptive market hypothesis in the prewar and wartime Japanese stock market using a new market capitalization‐weighted price index. First, we find that the degree of market efficiency varies over time and with major historical events. This implies that the hypothesis is supported in this market.

Testing the nullity of GARCH coefficients : correction of the standard tests and relative efficiency comparisons [PDF]
This article is concerned by testing the nullity of coefficients in GARCH models. The problem is non standard because the quasi-maximum likelihood estimator is subject to positivity constraints.

Allergy, EarlyView.Nasal epithelial transcriptomics identified three cytokine‐associated epithelial immune programs linked to childhood asthma phenotypes. Age‐associated epithelial polarization shifted from IFN/type‐17‐associated toward type‐2‐associated programs after 3 years of age.

Clinical Genetics, EarlyView.Heterozygous de novo nonsense variants in the penultimate and last exons of NUSAP1 were identified in two unrelated individuals, predicted to escape NMD. In population data, nonsense variants were observed in exons 1–9 (of 11) in NUSAP1 but were absent from its 3′‐terminal region.

Optimal Hedging Strategies in the Low‐Sulphur Bunker Fuel Landscape
European Financial Management, EarlyView.ABSTRACT The IMO2020 regulation for the green transition in shipping turned the industry into using two compliant bunker fuels: very low‐sulphur fuel oil (VLSFO) and low‐sulphur marine gas oil (LSMGO). VLSFO futures contracts introduced in late 2019 and other energy‐related futures contracts indicate that the VLSFO contracts trading on the Singapore ...
