Incorporation Of Polarization Into The Dirsig Synthetic Image Generation Model, Jason P. Meyers, John R. Schott, Scott D. Brown Nov 2002

Incorporation Of Polarization Into The Dirsig Synthetic Image Generation Model, Jason P. Meyers, John R. Schott, Scott D. Brown

Articles

The Digital Imaging and Remote Sensing Synthetic Image Generation (DIRSIG) model uses a quantitative first principles approach to generate synthetic hyperspectral imagery. This paper presents the methods used to add modeling of polarization phenomenology. The radiative transfer equations were modified to use Stokes vectors for the radiance values and Mueller matrices for the energy-matter interactions. The use of Stokes vectors enables a full polarimetric characterization of the illumination and sensor reaching radiances. The bi-directional reflectance distribution function (BRDF) module was rewritten and modularized to accommodate a variety of polarized and unpolarized BRDF models. Two new BRDF models based on Torrance- …


Elastic Ladar Modeling For Synthetic Imaging Applications, Robin R. Burton, John R. Schott, Scott D. Brown Nov 2002

Elastic Ladar Modeling For Synthetic Imaging Applications, Robin R. Burton, John R. Schott, Scott D. Brown

Articles

The Digital Imaging and Remote Sensing Image Generation (DIRSIG) model is a synthetic imagery generation model developed at the Center for Imaging Science (CIS) at the Rochester Institute of Technology (RIT). It is a quantitative first principle based model that calculates the sensor reaching radiance from the visible through to the long wave infrared on a spectral basis. DIRSIG generates a very accurate representation of what a sensor would see by modeling all the processes involved in the imaging chain. Currently, DIRSIG only models passive sources such as the sun and blackbody radiation due to the temperature of an object. …


Anisomycin Activates Jnk And Sensitises Du 145 Prostate Carcinoma Cells To Fas Mediated Apoptosis, James Curtin, Thomas Cotter Nov 2002

Anisomycin Activates Jnk And Sensitises Du 145 Prostate Carcinoma Cells To Fas Mediated Apoptosis, James Curtin, Thomas Cotter

Articles

Treatment of the hormone refractory prostate cancer cell line DU 145 with sublethal concentrations of chemotherapeutic drugs has been reported to sensitise these cells to Fas mediated apoptosis. However, the mechanism by which this occurs has not been determined. Our group has shown that inhibition of JNK activity completely abrogates the effects of chemotherapeutic drugs. Using anisomycin, a potent JNK agonist, we have demonstrated a role for JNK in Fas mediated apoptosis in DU 145 cells. Inhibition of Caspase 8 and Caspase 9 completely inhibits this process which suggests that DU 145 cells require mitochondrial amplification of the Fas apoptotic …


Many-To-Many Invocation: A New Framework For Building Collaborative Applications In Ad Hoc Networks, Hans-Peter Bischof, Alan Kaminsky Nov 2002

Many-To-Many Invocation: A New Framework For Building Collaborative Applications In Ad Hoc Networks, Hans-Peter Bischof, Alan Kaminsky

Articles

Many-to-Many Invocation (M2MI) is a new paradigm for building collaborative systems that run in wireless proximal ad hoc networks of fixed and mobile computing devices. M2MI is useful for building a broad range of systems, including service discovery frameworks; groupware for mobile ad hoc collaboration; systems involving networked devices (printers, cameras, sensors); and collaborative middleware systems. M2MI provides an object oriented method call abstraction based on broadcasting. An M2MI invocation means ``Every object out there that implements this interface, call this method.''. M2MI is layered on top of a new messaging protocol, the Many-to-Many Protocol (M2MP), which broadcasts messages to …

Ion Contribution To The Astrophysical Important 447.15, 587.56 And 667.82 Nm He I Spectral Lines Broadening, Vladimir Milosavljevic, Stevan Djenize

Articles

Characteristics of the astrophysical important Stark broadened 447.15 nm, 587.56 nm and 667.82 nm spectral line profiles have been measured at electron densities between 0.3 10 and 8.2 10 m and electron temperatures between 8000 and 33 000 K in plasmas created in five various discharge conditions using a linear, low-pressure, pulsed arc as an optically thin plasma source operated in a helium-nitrogen-oxygen gas mixture. On the basis of the observed asymmetry of the line profiles we have obtained their ion broadening parameters ( A) caused by influence of the ion microfield on the line broadening mechanism and also …


Use Of Physics Based Models In Hyperspectral Image Exploitation, John Schott, Kyungsuk Lee, Rolando Raqueno Oct 2002

Use Of Physics Based Models In Hyperspectral Image Exploitation, John Schott, Kyungsuk Lee, Rolando Raqueno

Articles

This paper describes a concept for using physics based models to support exploitation of remotely sensed image spectrometer data. It then reviews several methods from the literature illustrating more specifically how physics based models have been used as part of atmospheric correction, water quality assessment and temperature measurement algorithms. Finally a new approach for using model based techniques for subpixel target detection is presented This technique builds on a previously introduced invariant method that uses physics based models to support target detection of fully resolved targets without requiring in scene training or atmospheric correction. An example using the new subpixel …


Speckle Observations Of Binary Stars With The Wiyn Telescope. Iii. A Partial Survey Of A, F, And G Dwarfs, Elliott P. Horch, Sarah Robinson, Zoran Ninkov, William F. Van Altena, Reed D. Meyer, Sean E. Urban, Brian D. Mason Oct 2002

Speckle Observations Of Binary Stars With The Wiyn Telescope. Iii. A Partial Survey Of A, F, And G Dwarfs, Elliott P. Horch, Sarah Robinson, Zoran Ninkov, William F. Van Altena, Reed D. Meyer, Sean E. Urban, Brian D. Mason

Articles

Two hundred thirty nearby main-sequence stars with spectral types in the range of A to G have been observed by way of speckle interferometry using the WIYN 3.5 m telescope at Kitt Peak, Arizona. The stars had no previous mention of duplicity in the literature. Of those observed, 14 showed clear evidence of a companion, and 63 were classified as suspected nonsingle based on a power spectrum analysis. The remaining stars discussed show no evidence of duplicity to the limit of the detection system in high-quality observations.


Evaluating The 1931 Cie Color-Matching Functions, Mark Shaw, Mark Fairchild Aug 2002

Evaluating The 1931 Cie Color-Matching Functions, Mark Shaw, Mark Fairchild

Articles

The use of colorimetry within industry has grown extensively in the last few decades. Central to many of today's instruments is the CIE system, established in 1931. Many have questioned the validity of the assumptions made by Wright1 and Guild,2 some suggesting that the 1931 color-matching functions are not the best representation of the human visual system's cone responses. A computational analysis was performed using metameric data to evaluate the CIE 1931 color-matching functions as compared to with other responsivity functions. The underlying assumption was that an optimal set of responsivity functions would yield minimal color-difference error between pairs of …


Geospatial Data Handling For Web-Based And Mobile Applications, James Carswell Jul 2002

Geospatial Data Handling For Web-Based And Mobile Applications, James Carswell

Articles

One of the main bottlenecks for web-based GIS usability is in the transmission and handling of the vast amounts of geospatial data involved. The shear volume of raster, vector, attribute, and other data to be analysed, queried, transmitted and displayed over the WWW in real-time is prohibited by connection speeds. In this paper we introduce e-Spatial technology, a fully integrated open standard web-based solution to manage multiple spatial relationships directly in an Oracle Spatial database and to deploy in real-time spatially enabled (or standard) applications completely independent of data volume. Indeed, no application code is ever installed on the client …


Regulation And Measurement Of Oxidative Stress In Apoptosis, James Curtin, Maryanne Donovan, Thomas Cotter Jul 2002

Regulation And Measurement Of Oxidative Stress In Apoptosis, James Curtin, Maryanne Donovan, Thomas Cotter

Articles

Cells are constantly generating reactive oxygen species (ROS) during aerobic metabolism. As a consequence, each cell is equipped with an extensive antioxidant defence system to combat excessive production of ROS. Oxidative stress occurs in cells when the generation of ROS overwhelms the cell's natural antioxidant defences. There is a growing consensus that oxidative stress and the redox state of a cell plays a pivotal role in regulating apoptosis, a tightly controlled form of cell death in which a cell partakes in its own demise. More recently, a role for reactive nitrogen species (RNI) as both positive and negative regulators of …


The 2001 Superoutburst Of Wz Sagittae, Joseph Patterson, Gianluca Masi, Michael Richmond, Stacey Davis, Tracy Davis, Et Al. Jun 2002

The 2001 Superoutburst Of Wz Sagittae, Joseph Patterson, Gianluca Masi, Michael Richmond, Stacey Davis, Tracy Davis, Et Al.

Articles

We report the results of a worldwide campaign to observe WZ Sagittae during its 2001 superoutburst. After a 23-year slumber at V=15.5, the star rose within 2 days to a peak brightness of 8.2, and showed a main eruption lasting 25 days. The return to quiescence was punctuated by 12 small eruptions, of ~1 mag amplitude and 2 day recurrence time; these “echo outbursts” are of uncertain origin, but somewhat resemble the normal outbursts of dwarf novae. After 52 days, the star began a slow decline to quiescence. Periodic waves in the light curve closely followed the pattern seen in …


Conversion Of Aniline To Azobenzene At Functionalized Carbon Nanotubes: A Possible Case Of A Nanodimensional Reaction, M. Croston, J. Langston, Gerald A. Takacs, Terence C. Morrill, Massoud Miri, K.S.V. Santhanam, Pulickel Ajayan Jun 2002

Conversion Of Aniline To Azobenzene At Functionalized Carbon Nanotubes: A Possible Case Of A Nanodimensional Reaction, M. Croston, J. Langston, Gerald A. Takacs, Terence C. Morrill, Massoud Miri, K.S.V. Santhanam, Pulickel Ajayan

Articles

Aniline is oxidized to nitrosobenzene as the initial product, which undergoes further oxidation to nitrobenzene. The nitrosobenzene formation is catalyzed by functionalized multiwalled carbon nanotubes (CNT) followed by a coupling reaction between nitrosobenzene and aniline to produce azobenzene. This coupling requires close proximity of the reactants. It proceeds rapidly resulting in the UV-VIS absorption spectrum showing maxima at 327 nm and 425 nm. The nitrosobenzene yield in the presence of CNTs is controlled by the amount present in the medium. As the reaction is not catalyzed by unfunctionalized CNTs or graphitic particles, the uniqueness of the functionalized multiwalled CNTs in …


Speckle Observations Of Binary Stars With The Wiyn Telescope. Ii. Relative Astrometry Measures During 1998-2000, Elliott P. Horch, Sarah Robinson, Reed D. Meyer, William F. Van Altena, Zoran Ninkov, Albert Piterman Jun 2002

Speckle Observations Of Binary Stars With The Wiyn Telescope. Ii. Relative Astrometry Measures During 1998-2000, Elliott P. Horch, Sarah Robinson, Reed D. Meyer, William F. Van Altena, Zoran Ninkov, Albert Piterman

Articles

Five hundred twelve relative astrometry measures are presented for 253 double stars, including 53 double stars discovered by Hipparcos. In 15 cases, relative astrometry is reported for the first time for newly confirmed pairs. In addition, 20 high-quality nondetections of companions are reported for stars suspected of being nonsingle by Hipparcos. Observations were taken using a fast-readout CCD camera system at the WIYN 3.5 m telescope at Kitt Peak, Arizona. In comparing these measures with ephemeris predictions for binary stars with very well known orbits, we find that the measurement precision is better than 3 mas in separation and 1° …

Articles

The parity nonconserving spin rotation of neutrons in the 0.734-eV p-wave resonance of La-139 was measured with the neutron transmission method. Two optically polarized He-3 cells were used before and behind a 5-cm long La-139 target, each as a polarizer and an analyzer for neutron spin. The rotation angle was carefully measured by flipping the direction of He-3 polarization in the polarizer in sequence. The peak-to-peak value of the spin rotation was determined to be (7.4+/-1.1) x 10(-3) rad/cm. The result is found to be consistent with the previous experiments, but the result was statistically improved. The s-p mixing model …

Written surveys and semistructured qualitative interviews before and after a neutral PSA counseling intervention. PARTICIPANTS. Men 40 to 65 years of age in southeastern Michigan were recruited until thematic saturation—that is, the point at which no new themes emerged in interviews (n = 40). RESULTS. In a paper survey, 37 of 40 participants (93%) said that they interpreted the …


Lvdelta Is A Mesoderm-Inducing Signal In The Sea Urchin Embryo And Can Endow Blastomeres With Organizer-Like Properties, Hyla Sweet, Michael Gehring, Charles Ettensohn Apr 2002

Lvdelta Is A Mesoderm-Inducing Signal In The Sea Urchin Embryo And Can Endow Blastomeres With Organizer-Like Properties, Hyla Sweet, Michael Gehring, Charles Ettensohn

Articles

Signals from micromere descendants play a critical role in patterning the early sea urchin embryo. Previous work demonstrated a link between the induction of mesoderm by micromere descendants and the Notch signaling pathway. In this study, we demonstrate that these micromere descendants express LvDelta, a ligand for the Notch receptor. LvDelta is expressed by micromere descendants during the blastula stage, a time when signaling has been shown to occur. By a combination of embryo microsurgery, mRNA injection and antisense morpholino experiments, we show that expression of LvDelta by micromere descendants is both necessary and sufficient for the development of two …

Stark Shifts And Transition Probabilities In The Ne Ii Spectrum, Stevan Djenize, Vladimir Milosavljevic, Milan S. Dimitrijevic Jan 2002

Stark Shifts And Transition Probabilities In The Ne Ii Spectrum, Stevan Djenize, Vladimir Milosavljevic, Milan S. Dimitrijevic

Articles

Stark shifts (d) and transition probabilities of the spontaneous emission (Einstein's A values) of forty two singly charged neon ( ) ion spectral lines have been measured in a linear, low pressure, pulsed arc at 35 300 K electron temperature and 1.83 10 23 m -3 electron density. Transition probabilities have been obtained using the relative line intensity ratio (RLIR) method. Stark shift values have also been calculated, using the semiclassical perturbation formalism (SCPF). The measured and calculated shift values and the measured A values have been compared to the existing data taken from available data sources.

Switching The Default Rule, Cass R. Sunstein Jan 2002

Switching The Default Rule, Cass R. Sunstein

Articles

There is a standard analysis of default rules in contract law, including those forms of contract law that fall under the label of employment law. But behavioral economics raises many complications. Professor Cass R. Sunstein explains that the default rule can create an endowment effect, making employees value certain rights more, simply because they have been granted such rights in the first instance. New evidence, based on a survey of law students, is introduced to show a significant endowment effect in the context of vacation time. Similarly, the default rule for savings plans, set by employers or by law, seems …


Initiation Of Apoptosis In Cells Exposed To Medium From The Progeny Of Irradiated Cells: A Possible Mechanism For "Bystander" Induced Genomic Instability., Fiona Lyng, B. Maguire, B. Mcclean, C. Seymour, Carmel Mothersill Jan 2002

Initiation Of Apoptosis In Cells Exposed To Medium From The Progeny Of Irradiated Cells: A Possible Mechanism For "Bystander" Induced Genomic Instability., Fiona Lyng, B. Maguire, B. Mcclean, C. Seymour, Carmel Mothersill

Articles

Much evidence now exists regarding radiation-induced bystander effects, but the mechanisms involved in the transduction of the signal are still unclear. The mitogen-activated protein kinase (MAPK) pathways have been linked to growth factor-mediated regulation of cellular events such as proliferation, senescence, differentiation and apoptosis. Activation of multiple MAPK pathways such as the ERK, JNK and p38 pathways have been shown to occur after exposure of cells to radiation and a variety of other toxic stresses. Previous studies have shown oxidative stress and calcium signaling to be important in radiation-induced bystander effects. The aim of the present study was to investigate …

Philippic.Com, Cass R. Sunstein

Articles

A recent trend in so-called "second generation" legal commentary about the Internet suggests that, though it is an unparalleled communication medium and a means of engaging in global e-commerce, it is not an unmitigated force for good. Instead, the Net poses a fundamental danger to democracy. This trend takes shape in works by well-known cyberlaw theorists like Lawrence Lessig, Andrew Shapiro, and Neil Weinstock Netanel, but the most recent and most troubling criticism lies in Professor Cass Sunstein 's Republic.com. In this book, Professor Sunstein argues that perfect filtering of information on the Internet will lead to a fractured communications …
