Yutian (Cry to Heaven) is the third Chinese stage adaptation of Harriet Beecher Stowe’s novel Uncle Tom’s Cabin between 1907 and 2007. The first, Heinu yutian lu (Black Slave’s Cry to Heaven) by Zeng Xiaogu, was staged by Chinese students in Tokyo in 1907; the second, Heinu hen (Regret of...
Tidal energy dissipation is estimated for eight semi‐diurnal and diurnal constituents using a global inverse solution constrained by TOPEX/Poseidon altimeter data. Very similar spatial patterns are obtained for all semi‐diurnal constituents, with about one third of the total dissipation occurring in the deep ocean over rough topography. Maps for diurnal...
Amber preserves microscopic, soft-bodies organisms and is a good medium in which to trace the evolution of pathogen-vector associations. Spirochetes-like cells (Spirochaetales: Spirochaetaceae) in the hemocoel and lumen of the alimentary tract of a larva tick (Amblyomma sp. Arachnida: Ixodidae) in Dominican amber are described in the collective fossil genus...
Two new species of cicada hatchlings in Burmese and Dominican amber are described as Novicicada burmanica n. gen., n. sp. and N. youngi n. gen., n. sp. in the new collective genus Novicicada n. gen. (Hemiptera: Cicadidae). Diagnostic characters of the new genus are an elongate, flattened body, all antennomeres...
Gramene (http://www.gramene.org) is a comparative genome mapping database for grasses and a community resource for rice. Rice, in addition to being an economically important crop, is also a model monocot for understanding other agronomically important grass genomes. Gramene replaces the existing AceDB database ‘RiceGenes’ with a relational database based on...
What value does federal designation add to open space resources that are not all federally owned and managed? Over the years the federal government, under the auspices of the National Park Service and USDA Forest Service, has designated trails across the United States as National Recreation Trails. A survey of...
The tachinid species Ormia Dominicana, Ormia lineifrons, and Sitophaga aurigera were observed to aggregate atop 2 towers in central Florida shortly after sunset. The activity period for each species was brief, and that of 0. dominicana was temporally separated from that of S. aurigera. Aggregations occasionally exceeded 100 individuals of...
The hepatotoxic alkaloids known to occur in tansy ragwort (Senecio jacobaea L.) are also present in honey produced from the nectar of this species. These alkaloids, which include senecionine, seneciphvlline, jacoline, jaconine, jacobine, and jacozine, are potentially carcinogenic, mutagenic and teratogenic and may pose health hazards to the human consumer.
In this Letter, we investigate the slow-light effect of subwavelength diffraction gratings via the Rayleigh anomaly using a fully analytical approach without needing to consider specific grating structures. Our results show that the local group velocity of the transmitted light can be significantly reduced due to the optical vortex, which...
Hop (Humulus lupulus L.) is a perennial, dioecious species in which the female inflorescence (cones) are harvested and used in the beer-brewing process to impart bittering and/or flavoring to beer. Hop breeders have typically utilized clonal selection and hybridization to develop new cultivars. The use of genetically diverse parents for...
