Iron‐Mediated Release of Aged Dissolved Organic Carbon From Waterlogged Peatland Under Warming

open access: yesAdvanced Science, EarlyView.
This study conducts a five‐year in situ warming experiment in high‐altitude peatlands to examine dissolved organic carbon (DOC) release. The study shows that warming promotes the release of plant‐derived modern DOC in drained peatlands, but amplifies aquatic export of century‐old DOC from waterlogged peatlands via Fe‐mediated DOC mobilization—a ...

Multifractal relationship between decomposed oil price shocks and trading volume

open access: yesHumanities & Social Sciences Communications
The decomposition of oil price shocks is crucial for understanding the multifractal nature of price-volume dynamics in crude oil futures. Using the structural vector autoregression (SVAR), this study decomposes the crude oil futures prices into three ...

Investigating effects of oil price changes on the US, the UK and Japan [PDF]

open access: yes
Based on the structural VAR model of the global crude oil market proposed by Kilian(2009), this article investigates the causes for wild fluctuations in oil prices since the mid-2000s. A main contribution of the study is to compare the effects of changes

An Artificially Selected Cytokinin‐Pathway Transcription Factor Balances Soybean Yield and Pathogen Resistance

open access: yesAdvanced Science, EarlyView.
A cytokinin pathway transcription factor, RR2b, was artificially selected during soybean domestication and improvement based on its differential transcriptional activity, which correlates with ATT repeat polymorphisms in its promoter. RR2b balances yield and defense by fine‐tuning its expression level and offers a promising target for decoupling trade ...

Gasoline and crude oil prices: why the asymmetry? [PDF]

open access: yes
Many consumers complain that gasoline and crude oil prices have an asymmetric relationship in which gasoline prices raise more quickly when crude oil prices are rising than they fall when crude oil prices are falling.

A Global Methane Observation System to Reduce Uncertainty for Anthropogenic and Natural Sources and Sinks for Detecting and Attributing Climate Feedbacks

open access: yesAdvanced Science, EarlyView.
Conceptual illustration of a Global Ecosystem Methane Observing System (GEM‐OS) integrating satellites, aircraft, atmospheric networks, and ecosystem measurements to quantify methane emissions from anthropogenic and natural sources. The multi‐scale observing framework improves source attribution, reduces uncertainty in regional methane budgets, and ...

The dynamics of crude oil price differentials [PDF]

open access: yes, 2008
We model crude oil price differentials as a two-regime threshold autoregressive (TAR) process using Caner and Hansen’s (2001) method. While standard unit root tests, such as the Augmented Dickey–Fuller (ADF), are inconclusive in some instances on whether

Time-varying Predictability in Crude Oil Markets: The Case of GCC Countries [PDF]

open access: yes
This paper uses a time-varying parameter model with generalized autoregressive conditional heteros-cedasticity effects to examine the dynamic behavior of crude-oil prices for the period 1997-2008.

A Sustainable Bio‐Based Epoxy Thermoset as a High‐Performance Alternative to BPA‐Based Resins

open access: yesAdvanced Science, EarlyView.
A rigid–flexible bio‐based epoxy network integrates soybean oil, lignin, and maleic anhydride to overcome the strength–toughness–sustainability trade‐off of conventional BPA epoxy. The thermoset delivers excellent performance as both a structural adhesive and a matrix for glass‐fabric composites, while enabling pH‐responsive degradation, environmental ...
