Plant viruses of the recently recognized family Amalgaviridae have monopartite double-stranded (ds) RNA genomes
and encode two proteins: an RNA-dependent RNA polymerase (RdRp) and a putative capsid protein (CP). Whereas the
RdRp of amalgaviruses has been found to be most closely related to the RdRps of dsRNA viruses of the...

Plant viruses of the recently
Viruses and other selfish genetic elements are dominant entities in the biosphere, with respect to both physical abundance and genetic diversity. Various selfish elements parasitize on all cellular life forms. The relative abundances of different classes of viruses are dramatically different between prokaryotes and eukaryotes. In prokaryotes, the great majority...
The Pacific Walrus population that lives within the Chukchi Sea near Alaska and the Russian territory Siberia have traditionally held a diet composed of molluscs and benthic invertebrates, with the main dietary choice being clams or other bivalves. Due to global warming, the availability of stable ice resting surfaces has...
Cytoplasmic dynein is an ATP-dependent, microtubule-based molecular motor involved in the positioning and trafficking of cellular cargo. The cargo binding sub-domain of dynein contains the natively disordered intermediate chain (IC) and the homodimeric light chains (Tctex1, LC8 and LC7). The structure and stoichiometry of this complex, how the light chains...
Multiphase flow dynamics are important in many naval and turbomachinery applications, where bubble interaction with low pressure, vortical structures can lead to undesirable cavitation effects. To better understand the underlying phenomena, a multiscale numerical framework is developed to simulate bubble laden flow in dynamic hydro propulsion systems. Several subproblems in...
The dream of ubiquitous virtual reality (VR) tools has been a powerful presence in pop culture since before the turn of the century. But for all of its charm, VR applications are few and far between due to the high cost of hardware setups and cumbersome form factor. This project...
Establishing a therapeutic alliance or a therapeutic bond has long been seen as an essential component of obtaining positive treatment outcomes in clinical practice. More recently, the idea of recognizing therapeutic alliance ruptures (disagreements about the tasks or goals of therapy or a problem in the therapeutic bond) during counseling...
Per- and polyfluoroalkyl substances (PFAS) are a group of anthropogenic compounds gaining notoriety as contaminants of emerging concern. With the frequent detection of PFAS in the environment, drinking water, and consumer products, awareness and concern from the public regarding PFAS is increasing. The two most notorious PFAS are perfluorooctanoate (PFOA)...
New data are presented that provide evidence for the onset of extensional deformation in the Northwestern Basin and Range within 1 million years after the eruption of the Steens Basalt at 16.5 Ma. New geologic mapping (1:24,000), stratigraphic sections, and ⁴⁰Ar/³⁹Ar dating of the Crane Basin rocks provide a control...
