Cervicothoracic trans-spinal magnetic stimulation: effect of coil position and orientation on spinal motor evoked potentialsNARA Subscribed
Stroke is a leading cause of long-term adult disability, and over 80% of survivors have persistent upper limb motor impairment. Spinal electrical stimulation has shown therapeutic potential after neurological disorders. Post-stroke applications have largely relied on invasive implants that limit clinical adoption, and non-invasive high intensity electrical stimulation may be intolerable for those with residual sensory function...
Calibration and validation of the safer evapotranspiration model using Landsat 8 and eddy covariance data in vineyardsNARA Subscribed
Accurate estimates of actual evapotranspiration (ET a ) are essential for irrigation management in vineyards. This study locally calibrated and validated the Simple Algorithm for Evapotranspiration Retrieving (SAFER) model for California vineyard systems using Landsat 8 imagery and multi-year eddy covariance (EC) measurements collected between 2013 and 2016 in the Central Valley of California. Two calibration approaches were i...
Molecular phylogenetics suggest Osmiopsis (Asteraceae) could be a rare inter-subtribal hybrid genus on HispaniolaNARA Subscribed
Osmiopsis (Asteraceae, Eupatorieae) is endemic to Hispaniola and one of the seven genera of subtribe Praxelinae. When Osmiopsis was established in 1975, the authors hypothesized it was a hybrid and proposed Chromolaena (subtribe Praxelinae) and Koanophyllon (subtribe Critoniinae) as putative parent genera. To clarify its origin, a phylogenetic investigation of subtribe Praxelinae, reconstructed within a matrix of 80 genera/202...
Mercury (Hg), and specifically methylmercury (MeHg), is a contaminant of global concern to humans and wildlife, but there is still limited understanding of its effects on many taxa. Amphibians are closely associated with water, where Hg is converted to MeHg, and high concentrations of MeHg can reduce survival of amphibians in the wild. However, limited non-lethal proxies exist for estimating MeHg bioaccumulation in amphibian l...
Influence of Plant Secondary Metabolites on intake, Detoxification Costs, and Microbial Communities in DeerNARA Subscribed
Plants available to wild herbivores, especially browsers, often contain plant secondary metabolites (PSMs). Herbivores have evolved behavioral, physiological, and microbial mechanisms for avoiding and detoxifying PSMs. The detoxification limitation hypothesis suggests that herbivores can reduce toxicity by consuming a mixture of PSMs to avoid overloading a particular detoxification pathway. Although this hypothesis has been ex...
Understanding cachexia and muscle dysfunction in the context of metastatic breast cancerNARA Subscribed
Cancer cachexia significantly impacts the quality of life of cancer patients, predicting therapy response and survival. Cachexia prevalence and severity increases over the course of disease progression, affecting up to 80% of patients with metastatic cancer. Despite this, cachexia is relatively understudied in the context of metastatic breast cancer, despite it affecting a significant proportion of patients with this common ca...
Global ocean models at non-eddying resolutions currently used for subseasonal to seasonal to decadal (S2S2D) prediction suffer from a severe deficit in internal variability. In ensemble data assimilation (DA), this can lead to under-dispersed ensembles that require inflation schemes. However, inflation corrections do not persist into the forecast phase, causing ensemble spread to collapse at longer lead times. This study evalu...
Dissolved oxygen (DO) dynamics in estuarine ecosystems are shaped by both anthropogenic activities and climate variability, which jointly influence oxygen concentrations and overall ecosystem health. This study examined temporal and spatial variations in DO across three coastal sectors in Eastern South America. DO levels were classified as hypoxia (<2.0mgL-¹),intermediate(2.0–4.0mgL¹), and optimum (>4.0mgL-¹).Hypoxia was assoc...
