Multifunctional Gelatin‐Based Smart Films Integrating Thermochromic Encryption, Temperature‐Regulated Photothermal Management, Reprocessability, and Biodegradability for Sustainable Applications

open access: yesAdvanced Science, EarlyView.
Multifunctional gelatin films synergizing thermochromic encryption, self‐regulating photothermal management, and closed‐loop recyclability offer sustainable solutions for intelligent packaging. ABSTRACT Multifunctional gelatin‐based smart films are engineered by incorporating hyperbranched polyglycerol (HBPG) as a plasticizer, dialdehyde β‐cyclodextrin

Modeling the influence of snow cover on low Arctic net ecosystem exchange

open access: yesEnvironmental Research Letters, 2013
The Arctic net ecosystem exchange (NEE) of CO _2 between the land surface and the atmosphere is influenced by the timing of snow onset and melt. The objective of this study was to examine whether uncertainty in model estimates of NEE could be reduced by ...

Comparison of boreal ecosystem model sensitivity to variability in climate and forest site parameters [PDF]

open access: yes, 2001
Ecosystem models are useful tools for evaluating environmental controls on carbon and water cycles under past or future conditions. In this paper we compare annual carbon and water fluxes from nine boreal spruce forest ecosystem models in a series of ...

Single‐Cell Mitochondrial Lineage Tracing Decodes Fate Decision and Spatial Clonal Architecture in Human Hematopoietic Organoids

open access: yesAdvanced Science, EarlyView.
This study repurposes mitochondrial DNA mutations as endogenous barcodes for lineage tracing in human pluripotent stem cell‐derived organoids. Integrated with transcriptomic and spatial data, it reveals NOTCH‐mediated stromal‐progenitor crosstalk orchestrates clonal dynamics and spatial zonation during early hematopoietic development, offering a non ...

The Carbon Balance of Two Contrasting Mountain Forest Ecosystems in Switzerland: Similar Annual Trends, but Seasonal Differences [PDF]

open access: yes, 2018
Net ecosystem exchange (NEE) of two contrasting mountain forest types in Switzerland was measured by eddy covariance (EC) measurements at a montane mixed forest, the Lägeren forest, over 5 years (2005-2009), and at a subalpine coniferous forest, the ...

Evolving Interpolating Models of Net Ecosystem CO2 Exchange Using Grammatical Evolution [PDF]

open access: yes, 2012
Accurate measurements of Net Ecosystem Exchange of CO2 between atmosphere and biosphere are required in order to estimate annual carbon budgets. These are typically obtained with Eddy Covariance techniques. Unfortunately, these techniques are often both noisy and incomplete, due to data loss through equipment failure and routine maintenance, and ...

Parasitic Plant–Host Interactions: Molecular Mechanisms and Agricultural Resistance Strategies

open access: yesAdvanced Science, EarlyView.
Parasitic plants devastate global agriculture through sophisticated molecular interactions with host crops. This review synthesizes current understanding of parasitic plant‐host interactions, from strigolactone‐mediated germination and haustorium formation to host defense mechanisms.

Fine‐Scale Evaluation of Carbon Exchange Capacity in Terrestrial Ecosystems of China: Leveraging Flux Data From Meteorological Stations for Enhanced Database Representation

open access: yesGeophysical Research Letters
Over the past two decades, China has experienced frequent extreme events and substantial land cover changes. Site‐scale assessments of net ecosystem exchange (NEE) are constrained by the fixed land cover types at eddy covariance towers and short ...

Grazing alters the biophysical regulation of carbon fluxes in a desert steppe

open access: yesEnvironmental Research Letters, 2013
To determine the role of grazing on CO _2 fluxes in a desert steppe, we used paired eddy-covariance systems to measure the net ecosystem exchange (NEE) and microclimate on adjacent pastures of grazed (GS) and ungrazed (FS) steppes on the Mongolian ...
