Remote Spectral Detection of Canopy Functional Dimensions Varying Within and Across Forest TypesNARA Subscribed
Global trait axes reveal overarching dimensions of plant functional variation. However, how these dimensions are spatially organized within and across forest types remains unclear. We combined drone‐based full‐range imaging spectroscopy with crown‐level measurements of 16 physiological, morphological and biochemical traits across temperate, subtropical and tropical forests in China to enable spatially‐explicit trait mapping. T...
Continuous Distillation for Drug Substance ManufacturingNARA Subscribed
Purpose Continuous distillation is widely used in the commodity and petrochemical industry to purify fine chemicals on massive industrial scales; however, this key separation strategy is largely unused within the pharmaceutical industry. This article investigates the development of a pilot-scale continuous distillation system for in-line removal of an excess amine reactant ( i.e. , tert-butylamine) when incorporated within an...
High Cost and Low Trust: Insights From Qualitative Commercial Fishing Cost Data in the Northeast United StatesNARA Subscribed
In fisheries management, socioeconomic data, specifically qualitative data analysis, is often underutilized. This study qualitatively analyzed a primary federal data collection effort in the Northeast United States, The Greater Atlantic Region Commercial Fishing Business Cost Survey. This analysis focused on how commercial harvester perceptions of business costs and the industry evolved during 2006–2022. The results show that...
Deceased calf-carrying by female Arctic killer whale suggests species-wide epimeletic behaviorNARA Subscribed
Carrying dead calves is an epimeletic behaviour (caregiving or attentive actions towards injured or dead individuals) documented in several social cetacean species. During focal follows using a drone, we recorded an adult female killer whale ( Orcinus orca ) in the eastern Canadian Arctic carrying a deceased calf by its pectoral fins. Although the calf possessed several injuries, the cause of death was unclear. Similar account...
Age-related differences in motor unit discharge rate modulation across contraction levelsNARA Subscribed
Age-related strength loss may reflect morphological and neural adaptations that differ between muscles. However, it is unclear how ageing affects motor unit (MU) discharge rate modulation and estimates of persistent inward currents (PICs) across contraction levels. Thirty young (24 ± 4 years) and thirty older adults (73 ± 4 years) underwent magnetic resonance imaging and performed unilateral isometric dorsiflexion and knee ext...
