Excerpt: Entomological Reprint Specialists have done a fine service to the field of entomology and the study of Lepidoptera in particular by making the first volume of Forbes\u27 work on the Lepidoptera of the northeastern states generally available. This volume remains the only comprehensive work on the numerous families included in the primitive moths, Microlepidoptera, Pyraloidea, and Bombycoidea for a major portion of North America

Regional Economic Impacts of Florida's Agricultural and Natural Resource Industries

The state of Florida has large industries producing fruits and vegetables, sugar, livestock, dairy and meat products, seafood, ornamental plants, forest products, phosphate rock, and an array of associated industries that provide supporting inputs and services, and conduct processing and manufacturing. There are distinct differences in the regional distribution of Florida's agricultural and natural resource industries. Economic characteristics and impacts were evaluated for the state of Florida and for eight separate regions of Florida. Each region is comprised of a core metropolitan area and a number of surrounding counties, as defined by the US Commerce Department, Bureau of Economic Analysis, based on employee commuting patterns and other factors. The Implan input-output analysis and social accounting software and associated databases for Florida counties were used to create economic models for each region and to estimate the total economic impacts of over 100 industry sectors in agriculture, natural resource and associated value-added manufacturing. Statewide economic impacts in the year 2000, expressed in year 2002 dollars, included industry output (sales) of $35.2 billion (Bn), with sales to markets outside the state (export shipments) of$19.4Bn, personal and business net income (value added) of $14.8Bn, and employment of 338,253 persons. The value added represented 3.1 percent of Florida's gross regional product. When the multiplier effects of export final demand on interindustry purchases and employee household spending are considered, the total economic impacts were estimated at$62.0Bn in output, $31.0Bn in value added, and 648,550 jobs. Regionally, total value added impacts of the agriculture and natural resource industries were greatest in the Orlando area ($4.31Bn), followed by Miami-Ft. Lauderdale ($3.61Bn), Tampa-St. Petersburg- Clearwater ($2.20Bn), Jacksonville ($1.47Bn), Sarasota-Bradenton ($1.10Bn), Tallahassee ($782 million), Ft. Myers-Cape Coral ($701 million), and Pensacola ($597 million). The largest industry groups in terms of total value added impacts were fruits and vegetables ($2.9Bn), environmental horticulture ($2.8Bn), forest products ($2.0Bn), agricultural inputs and services ($1.4Bn), and other food and fiber manufacturing ($1.7Bn), with lesser impacts for dairy products, field crops, livestock and meat products, mining, seafood products, sugar and confectionary products, and tobacco products. The total value added impact was $1,929 per capita, and the total employment impact was 40 jobs per 1000 residents. Economic impacts per capita and share of gross regional product indicated that the agriculture and natural resource industries were relatively more important in the Sarasota-Bradenton, Orlando, Jacksonville, and Tallahassee regions than for the state as a whole.Florida, agriculture and natural resource industries, economic impact, functional economic region, output, value added, employment, input-output models, multiplier, Implan, Agribusiness, Public Economics, Resource /Energy Economics and Policy,

The algebraic dichotomy conjecture for infinite domain Constraint Satisfaction Problems

We prove that an $\omega$-categorical core structure primitively positively interprets all finite structures with parameters if and only if some stabilizer of its polymorphism clone has a homomorphism to the clone of projections, and that this happens if and only if its polymorphism clone does not contain operations $\alpha$, $\beta$, $s$ satisfying the identity $\alpha s(x,y,x,z,y,z) \approx \beta s(y,x,z,x,z,y)$. This establishes an algebraic criterion equivalent to the conjectured borderline between P and NP-complete CSPs over reducts of finitely bounded homogenous structures, and accomplishes one of the steps of a proposed strategy for reducing the infinite domain CSP dichotomy conjecture to the finite case. Our theorem is also of independent mathematical interest, characterizing a topological property of any $\omega$-categorical core structure (the existence of a continuous homomorphism of a stabilizer of its polymorphism clone to the projections) in purely algebraic terms (the failure of an identity as above).Comment: 15 page

A new species of Dialeurodes Cockerell (Hemiptera: Aleyrodidae) on Schefflera Forst and Forst in Florida

Descriptions of pupal cases of Dialeurodes schefflerae, new species, as well as distribution records are presented. This species is known to occur in Florida, Hawaii and Puerto Rico appearing to feed only on species of Schefflera Forst and Forst. This restriction to plant hosts in the Asian genus Schefflera, along with its affinities with Dialeurodes agalmae Takahashi, Dialeurodes citri (Ashmead) and Dialeurodes kirkaldyi (Kotinsky), suggests it is an invasive species, probably endemic to the Asian region

Linear-phase approximation in the triangular facet near-field physical optics computer program

Analyses of reflector antenna surfaces use a computer program based on a discrete approximation of the radiation integral. The calculation replaces the actual surface with a triangular facet representation; the physical optics current is assumed to be constant over each facet. Described here is a method of calculation using linear-phase approximation of the surface currents of parabolas, ellipses, and shaped subreflectors and compares results with a previous program that used a constant-phase approximation of the triangular facets. The results show that the linear-phase approximation is a significant improvement over the constant-phase approximation, and enables computation of 100 to 1,000 lambda reflectors within a reasonable time on a Cray computer

Public Preferences and Values for Rural Land Preservation in Florida

This study develops a method to evaluate the influence of local geography on respondents values for land conservation programs. The study employs a choice experiment to evaluate alternative conservation plans. Results indicate that residents local landscapes do matter to the estimated values for such conservation programs. Our results also provide information about the divergence of political and economic jurisdictions for land conservation programs in Florida.Land Economics/Use,

A teleoperated unmanned rotorcraft flight test technique

NASA and the U.S. Army are jointly developing a teleoperated unmanned rotorcraft research platform at the National Aeronautics and Space Administration (NASA) Langley Research Center. This effort is intended to provide the rotorcraft research community an intermediate step between wind tunnel rotorcraft studies and full scale flight testing. The research vehicle is scaled such that it can be operated in the NASA Langley 14- by 22-Foot Subsonic Tunnel or be flown freely at an outside test range. This paper briefly describes the system's requirements and the techniques used to marry the various technologies present in the system to meet these requirements. The paper also discusses the status of the development effort

Magnetometry of random AC magnetic fields using a single Nitrogen-Vacancy center

We report on the use of a single NV center to probe fluctuating AC magnetic fields. Using engineered currents to induce random changes in the field amplitude and phase, we show that stochastic fluctuations reduce the NV center sensitivity and, in general, make the NV response field-dependent. We also introduce two modalities to determine the field spectral composition, unknown a priori in a practical application. One strategy capitalizes on the generation of AC-field-induced coherence 'revivals', while the other approach uses the time-tagged fluorescence intensity record from successive NV observations to reconstruct the AC field spectral density. These studies are relevant for magnetic sensing in scenarios where the field of interest has a non-trivial, stochastic behavior, such as sensing unpolarized nuclear spin ensembles at low static magnetic fields.Comment: 11 pages, 3 figure
