The Worldsheet Formulation as an Alternative Method for Simulating Dynamical Fermions
The recently proposed worldsheet formulation of lattice fermions is tested
for the first time carrying out a simulation for the simplest model: the
one-flavor, strictly massless lattice Schwinger model. A main advantage of this
alternative method for simulating dynamical fermions consists in its economy:
it involves many fewer degrees of freedom than the ordinary Kogut-Susskind
formulation. The known continuum limit is reproduced by the method for
relatively small lattices.Comment: 4 pages, 1 eps figure, revte
Limnological, Ichthyological, and Parasitological Investigations on Arkansas Reservoris in Relation to Water Quality
Lake Fort Smith, a 525 acre (212 ha) reservoir, was impounded in 1936 as a water supply for the city of Fort Smith. The reservoir is located on Clear Creek (Frog Bayou), a tributary of the Arkansas River, in the Boston Mountains 28 miles (45 km) northeast of the city of Fort Smith in Crawford County, Arkansas. A map and morphometric characteristics of Lake Fort Smith are given in Fig. 1 and Table I (Hoffman, 1951; Nelson, 1952). In 1956 Lake Shepherd Springs, a 750 acre (304 ha) impoundment, was created one mile upstream of Lake Fort Smith (Rorie, 1961). Both lakes have a shale substrate and are subject to periods of high turbidity. The 2 two lakes have a water shed of 65 square mile area (168 km ) of mountainous oak-hickory forest. Lake Shepherd Springs has not acted as a settling basin for sediments; thus, the upper portion of Lake Fort Smith has numerous shallow areas with a mud bottom supporting various submergent and emergent aquatic plants. The lower portion of the lake has a rocky, shale substrate with only limited emergent vegetation
