Anomalous trends in global ocean carbon concentrations following the 2022 eruptions of Hunga Tonga-Hunga Ha’apai

Communications Earth & Environment
We report on observed trend anomalies in climate-relevant global ocean biogeochemical properties, as derived from satellite ocean color measurements, that show a substantial decline in phytoplankton carbon concentrations following eruptions of the ...

CMB and Random Flights: temperature and polarization in position space [PDF]

JCAP06(2013)043, 2013
The fluctuations in the temperature and polarization of the cosmic microwave background are described by a hierarchy of Boltzmann equations. In its integral form, this Boltzmann hierarchy can be converted from the usual Fourier-space base into a position-space and causal description. We show that probability densities for random flights play a key role

The burden of intracranial atherosclerosis on cerebral small vessel disease: A community cohort study

Annals of Clinical and Translational Neurology, EarlyView.
Abstract Objective Exploring the prevalence and association between intracranial atherosclerosis (ICAS) and cerebral small vessel diseases (CSVD), this study delved beyond the current scope, utilising high‐resolution vessel wall MRI (HRVW‐MRI) to investigate how subtle changes in intracranial atherosclerotic features influence the various burdens of ...

Russian forests show strong potential for young forest growth

Communications Earth & Environment
Climate warming has improved conditions for boreal forest growth, yet the region’s fate as a carbon sink of aboveground biomass remains uncertain. Forest height is a powerful predictor of aboveground forest biomass, and access to spatially detailed ...

Satellite Observations of Phytoplankton Functional Type Spatial Distributions, Phenology, Diversity, and Ecotones

Frontiers in Marine Science, 2017
Phytoplankton functional diversity plays a key role in structuring the ocean carbon cycle and can be estimated using measurements of phytoplankton functional type (PFT) groupings. Concentrations of 18 phytoplankton pigments were calculated using a linear

Histone Deacetylase 6 Brain PET in Amyotrophic Lateral Sclerosis‐Frontotemporal Spectrum Disorder

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective [18F]EKZ‐001 is a positron emission tomography (PET) tracer targeting histone deacetylase 6 (HDAC6), an enzyme responsible for intracellular transport and clearance of misfolded proteins. HDAC6 modulation is a promising treatment strategy in neurodegenerative disorders, including amyotrophic lateral sclerosis (ALS).

In Situ Optimized Substrate Witness Plates: Ground Truth for Key Processes on the Moon and Other Planets

Earth and Space Science, 2023
Future exploration efforts of the Moon, Mars, and other bodies are poised to focus heavily on persistent and sustainable survey and research efforts, especially given the recent interest in a long‐term sustainable human presence at the Moon. Key to these

Effectiveness of a Telephone‐Delivered Walk With Ease Program on Arthritis‐Related Symptoms, Function, and Activity: A Randomized Trial

Arthritis Care &Research, EarlyView.
Objective Walk With Ease (WWE) is a six‐week arthritis‐appropriate evidence‐based physical activity program traditionally offered in a face‐to‐face format. Because many populations encounter participation barriers to in‐person programs, WWE was modified for telephone delivery (WWE‐T).

A shift in transitional forests of the North American boreal will persist through 2100

Communications Earth & Environment
High northern latitude changes with Arctic amplification across a latitudinal forest gradient suggest a shift towards an increased presence of trees and shrubs.

Chlorophyll Variability in the Oligotrophic Gyres: Mechanisms, Seasonality and Trends

Frontiers in Marine Science, 2015
A 16-year (1998-2013) analysis of trends and seasonal patterns was conducted for the five subtropical ocean gyres using satellite data: chlorophyll-a (Chl-a) retrievals from ocean color, sea surface temperature (SST), and sea-level anomaly (SLA).
