Indexing Flower Patent Images Using Domain Knowledge, Madirakshi Das, R. Manmatha, Edward M. Riseman
Indexing Flower Patent Images Using Domain Knowledge, Madirakshi Das, R. Manmatha, Edward M. Riseman
R. Manmatha
A new approach to indexing a specialized database by utilizing the color and spatial domain knowledge available for the database is described. This approach is illustrated by using it to provide a solution to the problem of indexing images of flowers for searching a flower patents database by color. The flower region is isolated from the background by using an automatic iterative segmentation algorithm with domain knowledge-driven feedback. The color of the flower is defined by the color names present in the flower region and their relative proportions. The database can be queried by example and by color names. The …
A Synthesis Of Lead Isotopes In Two Millennia Of European Air, Charles Dunlap, Eiliv Steinnes, A. Russell Flegal
A Synthesis Of Lead Isotopes In Two Millennia Of European Air, Charles Dunlap, Eiliv Steinnes, A. Russell Flegal
Charles Dunlap
Four airborne particulate records from ombrotrophic peat bogs in southern Norway, extending back 300 years, have been measured for chronology, lead concentration, and lead isotope composition. Since southern Norway receives an airborne lead signal that accumulates emissions from the European continent, the trend in the four bog records can be used to correlate previously reported measurements from France, Switzerland, England, and Greenland that cover different ranges of time. When these are compiled, the integrated European record that emerges spans the last 2300 years of human influence on lead in the air over Europe and suggests human control of lead in …

Multi-Modal Retrieval Of Trademark Images Using Global Similarity, S Ravela, R. Manmatha
R. Manmatha
In this paper a system for multi-modal retrieval of trademark images is presented. Images are characterized and retrieved using associated text and visual appearance. A user initiates retrieval for similar trademarks by typing a text query. Subsequent searches can be performed by visual appearance or using both appearance and text information. Textual information associated with trademarks is searched using the INQUERY search engine. Images are searched visually using a method for global image similarity by appearance developed in this paper. Images are filtered with Gaussian derivatives and geometric features are computed from the filtered images. The geometric features used here …

Semi-Insulating Semiconductor Heterostructures: Optoelectronic Properties And Applications, David D. Nolte
Semi-Insulating Semiconductor Heterostructures: Optoelectronic Properties And Applications, David D. Nolte
David D Nolte
This review covers a spectrum of optoelectronic properties of and uses for semi-insulating semiconductor heterostructures and thin films, including epilayers and quantum wells. Compensation by doping, implantation, and nonstoichiometric growth are described in terms of the properties of point defects and Fermi level stabilization and pinning. The principal optical and optoelectronic properties of semi-insulating epilayers and heterostructures, such as excitonic electroabsorption of quantum-confined excitons, are described, in addition to optical absorption by metallic or semimetallic precipitates in these layers. Low-temperature grown quantum wells that have an arsenic-rich nonstoichiometry and a supersaturated concentration of grown-in vacancies are discussed. These heterostructures experience …

Microlensing Of Circumstellar Envelopes I. Simplified Considerations For Diagnosing Radial And Azimuthal Flow., R. Ignace, M. A. Hendry
Richard Ignace
This paper presents first results on the line profile shapes from a circumstellar envelope in bulk motion as modified by a microlensing event. Only geometrically and optically thin spherical shells in uniform expansion or rotation are considered here so as to emphasise the information content available in the profile shapes. In particular it is demonstrated that for the case of expansion, the line emission can increase by significant factors and the time variation of the profile shape is symmetric about line centre. For uniform rotation the line emission also increases significantly, but the time evolution of the profile shape is …

OBJECTIVES: The goal of this study was to project the future prevalence and incidence of Alzheimer's disease in the United States and the potential impact of interventions to delay disease onset.
METHODS: The numbers of individuals in the United States with Alzheimer's disease and the numbers of newly diagnosed cases that can be expected over the next 50 years were estimated from a model that used age-specific incidence rates summarized from several epidemiological studies, US mortality rates, and US Bureau of the Census projections.
RESULTS: in 1997, the prevalence of Alzheimer's disease in the United States was 2.32 million (range: …

Two-Surface Virial Analysis Of Alkane Adsorption On Carbopack C With And Without Hydrogen Treatment., Chrystal Bruce, Thomas Rybolt, Howard Thomas, Tara Agnew, Brandon Davis
Chrystal D. Bruce
Second gas–solid virial coefficients for propane, butane, pentane, and hexane were found for Carbopack C and Carbopack C-HT (Supelco Inc.) within the temperature range of 323 to 471 K using gas–solid chromatography in the Henry's law region of adsorption. Carbopack C and Carbopack C-HT are both graphitized carbon black powders. Treatment of Carbopack C with hydrogen at 1273 K converts it to Carbopack C-HT and is believed to remove certain high energy sites or “hot spots” from the carbon surface. These two surfaces provide appropriate model systems to test a two-surface virial analysis. Surface areas for both powders were calculated …

The Penrose Dodecahedron Revisited, Padmanabhan Aravind, Jordan Massad
Padmanabhan K. Aravind
This paper gives an elementary account of the ‘‘Penrose dodecahedron,’’ a set of 40 states of a spin- 3 2 particle used by Zimba and Penrose @Stud. Hist. Phil. Sci. 24, 697–720 ~1993!# to give a proof of Bell’s nonlocality theorem. The Penrose rays are constructed here from the rotation operator of a spin- 3 2 particle and the geometry of a dodecahedron, and their orthogonality properties are derived and illustrated from a couple of different viewpoints. After recalling how the proof of Bell’s theorem can be reduced to a coloring problem on the Penrose rays, a ‘‘proof-tree’’ argument is …

Spectral Features Of The Stimulated Raman Backscattering Of Modulated Laser Pulses In A Plasma, Nikolai E. Andreev, Serguei Y. Kalmykov
Serge Youri Kalmykov
The characteristic features of the stimulated Raman backscattering of short modulated (multi-frequency) laser pulses in an underdense plasma are investigated. A laser pulse consisting of a given pair of spectral components with the frequency difference close to the double plasma frequency is studied in the weak mode coupling approximation. The scattering of the component with the higher frequency is shown to be a five-wave resonant process, and the conditions under which this process is totally suppressed are found. The scattering of the component with the lower frequency is an ordinary three-wave decay process without any suppression. When the difference between …

"Wcfields": A Magnetic Rotating Stellar Wind Model From Wind Compression Theory., R. Ignace, J. P. Cassinelli, J. E. Bjorkman
Richard Ignace
A stellar wind model for a magnetic rotating star is presented. We use the semianalytic wind compression model that predicts the two-dimensional geometry of outflows from rotating stars and consider the addition of a magnetic field. In the limit of weak magnetic fields, in such a way that the fields are unimportant in accelerating the flow, the wind compression model can be used to predict the magnetic field distribution throughout the wind, which is shown to follow the mass flux distribution. A compression of field lines near the equator results as the flow of material from higher latitudes brings magnetic …
A Heavy Top Quark From Flavor-Universal Colorons, Marko Popovic, Elizabeth Simmons
A Heavy Top Quark From Flavor-Universal Colorons, Marko Popovic, Elizabeth Simmons
Marko B. Popovic
Ordinary technicolor and extended technicolor cannot produce the heavy top quark unaided. We demonstrate that a flavor-universal extension of the color interactions combined with an extended hypercharge sector that singles out the third generation can provide the necessary assistance. We discuss current experimental constraints and suggest how collider experiments can search for the predicted new heavy gauge bosons.
Improved Treatment Of Loop Diagrams In Su(3) Baryon Chiral Perturbation Theory, Jf Donoghue, Br Holstein
Improved Treatment Of Loop Diagrams In Su(3) Baryon Chiral Perturbation Theory, Jf Donoghue, Br Holstein
Barry R Holstein
Baryon chiral perturbation theory as conventionally applied has a well-known problem with the SU(3) chiral expansion in that loop diagrams generate very large SU(3) breaking corrections and greatly upset the subsequent phenomenology. We argue that the problem comes from the portions of loop integrals corresponding to propagation at such short distances that the effective theory is not valid. One can reformulate the theory equally rigorously by regulating the loop integrals using a momentum-space cutoff which removes the spurious short-distance physics. We show that this reformulation improves the phenomenology for reasonable values of the cutoff.
