Structure–Function Decoupling of the Sensorimotor and Default Mode Networks in Black Americans With MS

open access: yesAnnals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Background and Objectives Multiple sclerosis (MS) exhibits racially disparate rates of disease progression. Black people with MS (B‐PwMS) experience a more severe disease course than non‐Hispanic White people with MS (NHW‐PwMS). Here we investigated structural and functional connectivity as well as structure–function decoupling in the ...

Fusing tree‐ring and forest inventory data to infer influences on tree growth

open access: yesEcosphere, 2017
Better understanding and prediction of tree growth is important because of the many ecosystem services provided by forests and the uncertainty surrounding how forests will respond to anthropogenic climate change.

Southwestern (U.S.A.) Archaeological Tree-Ring Dating: 1930-1942

open access: yesBulletin of the History of Archaeology, 1997
Dendrochronology, the science of assigning precise and accurate calendar dates to annual growth rings in trees (Stokes and Smiley 1968), was the first independent dating technique available to prehistorians.

Tree Rings: A Climate Record of the Past [PDF]

open access: yes
This activity will help students learn about how tree rings provide a record of past growing conditions and, by inference, climate. They use this principle to work out how cores from three different trees (three strips of paper marked with stripes to ...

Radiocarbon Calibration for Japanese Wood Samples [PDF]

open access: yes, 2003
The radiocarbon content of Japanese cedars was measured by accelerator mass spectrometry for decadal tree-ring samples from the period of 240 BC to AD 900. Conventional gas counting was also used for part of the samples.

Clinical Practice Guideline for Evaluation and Management of Peripheral Nervous System Manifestations in Sjögren's Disease

open access: yesArthritis Care &Research, EarlyView.
Objective Sjögren's disease is an autoimmune disorder that can impact multiple organ systems, including the peripheral nervous system (PNS). PNS manifestations, which can exist concurrently, include mononeuropathies, polyneuropathies, and autonomic nervous system neuropathies.

Oxygen Isotopes in Tree Rings Track Neotropical Climate Dynamics

open access: yesGeophysical Research Letters
Central America faces increasing risks from climate variability and extreme weather events. Limited observational records and model biases have constrained our ability to understand the ocean–atmosphere dynamics that influence precipitation variability ...

Placing 21st Century Warming in Southern California, USA in a Multi-Century Historical Context

open access: yesAtmosphere
Warming in southern California during the 21st century is unprecedented in the instrumental record. To place this warming in a multi-century historical context, we analyzed tree ring data sampled from Jeffrey pine (Pinus jeffreyi) and sugar pine (Pinus ...

Trajectories of Physical Function in Canadian Children With Juvenile Idiopathic Arthritis

open access: yesArthritis Care &Research, EarlyView.
Objective We describe trajectories of physical function in children newly diagnosed with juvenile idiopathic arthritis (JIA) and identify trajectories with persisting functional impairments and associated baseline characteristics. Methods We included patients enrolled in the Canadian Alliance of Pediatric Rheumatology Investigators (CAPRI) Registry ...

Increasing precipitation variability and climate-growth responses of five tree species in North Carolina, USA

open access: yesEnvironmental Research: Climate, 2023
We examined the effects of increasing summertime precipitation variability from 1950 to 2022 on the radial-growth responses of five tree species native to central North Carolina, USA.
