Seasonal patterns in B‐vitamins and cobalamin co‐limitation in the Northwest Atlantic

Limnology and Oceanography, EarlyView.
Abstract B‐vitamins are important co‐enzymes that have long been hypothesized to play key roles in marine ecosystems. However, environmental measurements remain scarce, which limits our understanding of their potential impact. Here, we present mass spectrometry‐based measurements of B‐vitamins (B1, B2, B3, B5, B6, B12) and related vitamers along a ...

Enhancing global aerosol retrieval from satellite data via deep learning with mutual information estimation

International Journal of Applied Earth Observations and Geoinformation
Satellite-based data can provide continuous aerosol observations but suffer from significant uncertainties across various regions. Transfer learning improves model generalization, yet its application in atmospheric research remains limited.

Volcanic Drivers of Stratospheric Sulfur in GFDL ESM4

Journal of Advances in Modeling Earth Systems, 2023
Stratospheric injections of sulfur dioxide from major volcanic eruptions perturb the Earth's global radiative balance and dominate variability in stratospheric sulfur loading.

Retrieval of canopy height using moderate-resolution imaging spectroradiometer (MODIS) data

Remote Sensing of Environment, 2011
article i nfo In this study we use the 500 m Moderate Resolution Imaging Spectroradiometer (MODIS) Bidirectional Reflectance Distribution Function (BRDF) product to develop multivariate linear regression models that estimate canopy heights over study sites at Howland Forest, Maine, Harvard Forest, Massachusetts and La Selva Forest, Costa Rica using (1)

High Antarctic coastal productivity in polynyas revealed by considering remote sensing ice‐adjacency effects

Limnology and Oceanography Letters, EarlyView.
Abstract Ocean color‐based estimates of Antarctic net primary productivity (NPP) have indicated low nearshore productivity in ice‐adjacent waters, contrasting with coupled physical–biogeochemical models. To understand this discrepancy, we assessed satellite records of polynya NPP by comparing field data with two satellite imagery datasets derived using

Balancing Charge Injection for Enhanced Efficiency in Inverted InP Quantum Dot Light‐Emitting Diodes

Advanced Quantum Technologies, EarlyView.
This study presents a charge injection control strategy for indium phosphide (InP)‐based quantum dot light‐emitting diodes (QLEDs) using a poly(4‐vinylpyridine) (PVPy) interlayer. The optimized structure doubled the external quantum efficiency (EQE) while maintaining luminance, highlighting the importance of balanced charge transport in cadmium‐free ...
