Measuring Changes in Phenology of Oklahoma Asteraceae Using Herbarium Specimens
(2021)
Analyzing shifts in plant flowering times (flowering phenology) in response to changing climate is crucial to understanding the impacts of climate change on plants. Herbaria contain the physical record of reproductive ...
Evolutionary determinism and convergence associated with water-column transitions in marine fishes
(2020-12-16)
Repeatable, convergent outcomes are prima facie evidence for determinism in evolutionary processes. Among fishes, well-known examples include microevolutionary habitat transitions into the water column, where freshwater ...
Vertical and Horizontal Agency Problems in Private Firms: Ownership Structure and Operating Performance
(2021)
We investigate how ownership structure influences op erating performance and implied agency costs. Our sample includes over 42,000 U.K. private and public firms. We document several new results of considerable economic ...
(NH4)2AgX3 (X = Br, I): 1D Silver Halides with Broadband White Light Emission and Improved Stability
(2021-06-17)
Recently, ternary copper(I) halides have emerged as alternatives to lead halide perovskites for light emission applications. Despite their high-efficiency photoluminescence (PL) properties, most copper(I) halides are blue ...
Raman Spectroscopy of High 1 Salinity Brines and Ices
(2022-01-01)
Raman spectroscopy is an ideal tool to analyze the geochemistry and mineralogy of heterogenous mixtures of solids, liquid, and gases in situ, while maintaining planetary protection protocols. Here we characterize saturated ...
The Case of Eleazar Edgar: Leicester’s Commonwealth and the Book Trade in 1604
(2021-06)
Scholars have long observed that the Catholic libel known as Leicester’s Commonwealth circulated extensively in manuscript. After its first printing in 1584, the tract was not printed again until 1641. Yet over ninety full ...
Experimental Investigation of Inhibitive Drilling Fluids Performance: Case Studies from United States Shale Basins
(2020-10-02)
Shale formations are attractive prospects due to their potential in oil and gas production. Some of the largest shale formations in the mainland US, such as the Tuscaloosa Marine Shale (TMS), have reserves estimated to be ...
Dietary sodium levels affect grasshopper growth and performance
(2021-03-08)
Anthropogenic activities are increasing terrestrial sodium availability through application of both saline irrigation water and road salt. Sodium often limits herbivore abundance, but less is known about the physiological, ...
Cerebrovascular responses to graded exercise in young healthy males and females
(2020-10-28)
Although systemic sex‐specific differences in cardiovascular responses to exercise are well established, the comparison of sex‐specific cerebrovascular responses to exercise has gone under‐investigated especially, during ...
Industrial research and development and real exchange rate depreciation in a small open economy
(2020-01-24)
To examine how changes in relative national prices affect innovation input, this paper studies the impact of changes in industry‐specific effective real exchange rates on industrial R&D expenditures in Korea. In particular, ...
