Western Gray Whales Off Sakhalin Island, Russia: A Joint Russia-U.S. Scientific Investigation July-September 2007, David W. Weller, Amanda L. Bradford, Aimée R. Lang, Hyun Woo Kim, Maxim Sidorenko, Grigory A. Tsidulko, Alexander M. Burdin, Robert L. Brownell Jr.

United States Department of Commerce: Staff Publications

A collaborative Russia-U.S. research program on western gray whales (Eschrichtius robustus) summering off northeastern Sakhalin Island, Russia, has been ongoing since 1995 and has produced important new information on the present day conservation status of this critically endangered population. This interim report reviews preliminary findings from 2007 research activities and combines such with data from previous years, in some cases ranging back to 1994. Photo-identification research conducted off Sakhalin Island in 2007 resulted in the identification of 83 whales, including nine calves and two previously unidentified non-calves. When combined with data from 1994-2006, a catalog of 169 photo-identified …

Entrepreneurial Stock Brokering And Switching Costs, G. Geoffrey Booth, Orkunt M. Dalgic, Juha-Pekka Kallunki, Petri Sahlström Dec 2007

Entrepreneurial Stock Brokering And Switching Costs, G. Geoffrey Booth, Orkunt M. Dalgic, Juha-Pekka Kallunki, Petri Sahlström

The Journal of Entrepreneurial Finance

Stock brokers are entrepreneurs who incur switching costs when the change brokerage houses. We use Helsinki Stock Exchange data to investigate these costs by examining whether investors are loyal to their brokers when brokers move. We find that investors who have extant relationships with the new house are more likely to attract the investors from the old houses, and savvy (knowledgeable) investors are more likely to stay with their broker.

Closed-Form Derivations Of Isi And Mui For Time-Reversed Ultra Wideband, K. Popovski, Beata J. Wysocki, Tadeusz Wysocki Dec 2007

Closed-Form Derivations Of Isi And Mui For Time-Reversed Ultra Wideband, K. Popovski, Beata J. Wysocki, Tadeusz Wysocki

Department of Electrical and Computer Engineering: Faculty Publications (to 2015)

Through transmitter pre-filtering, a time reversed UWB system is capable if harnessing a multipath channel to achieve temporal and spatial focusing. Unfortunately, large RMS channel delay spread leads to significant intersymbol and multiuser interference. This paper presents closed-form expressions for self and multi-user interference for a UWB system utilizing a time-reversed approach. The influence of user multiplexing codes is taken to account through incorporation of a ‘separation probability’, which characterizes a family of hopping sequences. The standardized IEEE 802.15.3a channel model is applied, and the derived performances are compared with that of a simulated time hopped time-reversed UWB system.

Constraints On An Optical Afterglow And On Supernova Light Following The Short Burst Grb 050813, P. Ferreo, S. F. Sanchez, D. A. Kann, S. Klose, J. Greiner, J. Gorosabel, Dieter H. Hartmann, A. A. Henden, P. Møller, E. Palazzi Dec 2007

Constraints On An Optical Afterglow And On Supernova Light Following The Short Burst Grb 050813, P. Ferreo, S. F. Sanchez, D. A. Kann, S. Klose, J. Greiner, J. Gorosabel, Dieter H. Hartmann, A. A. Henden, P. Møller, E. Palazzi

Publications

We report early follow-up observations of the error box of the short burst GRB 050813 using the telescopes at Calar Alto and Observatorio Sierra Nevada, followed by deep VLT FORS2 I-band observations obtained under very good seeing conditions 5.7 and 11.7 days after the event. Neither a fading afterglow nor a rising SN component was found, so the potential GRB host galaxy has not been identified based on a comparison of the two VLT images taken at different epochs. We discuss whether any of the galaxies present in the original 1000 XRTerror circle could be the host.In anycase, the optical …

Putting Expectations In Order, Alan Richard Baker Dec 2007

Putting Expectations In Order, Alan Richard Baker

Philosophy Faculty Works

In their paper, “Vexing Expectations,” Nover and Hájek (2004) present an allegedly paradoxical betting scenario which they call the Pasadena Game (PG). They argue that the silence of standard decision theory concerning the value of playing PG poses a serious problem. This paper provides a threefold response. First, I argue that the real problem is not that decision theory is “silent” concerning PG, but that it delivers multiple conflicting verdicts. Second, I offer a diagnosis of the problem based on the insight that standard decision theory is, rightly, sensitive to order. Third, I describe a new betting scenario—the Alternating St. …

Markov Processes In Single Molecule Fluorescence, David Talaga Dec 2007

Markov Processes In Single Molecule Fluorescence, David Talaga

Department of Chemistry and Biochemistry Faculty Scholarship and Creative Works

This article examines the current status of Markov processes in single molecule fluorescence. For molecular dynamics to be described by a Markov process, the Markov process must include all states involved in the dynamics and the first-passage time (FPT) distributions out of those states must be describable by a simple exponential law. The observation of non-exponential FPT distributions or other evidence of non-Markovian dynamics is common in single molecule studies and offers an opportunity to expand the Markov model to include new dynamics or states that improve understanding of the system.

Formation Of Peptide Nanospheres And Nanofibrils By Metal Coordination, Mikhail V. Tsurkan, Michael Y. Ogawa Dec 2007

Formation Of Peptide Nanospheres And Nanofibrils By Metal Coordination, Mikhail V. Tsurkan, Michael Y. Ogawa

Chemistry Faculty Publications

Two amphipathic polypeptides were coordinated to the cis positions of a square planar Pt(II) complex in order to provide the metal center with two noncovalent oligomerization domains. This resulted in the formation of new metal-peptide nanoassemblies which are shown to exist as nanometer-sized spheres and fibrils. Construction of these assemblies was based on the 30-residue polypeptide AQ-Pal14 which was designed for its ability to self-assemble into the common protein oligomerization motif of a noncovalent coiled-coil, and modified to contain a metal-binding 4-pyridylalanine residue at its surface. When AQ-Pal14 was reacted with Pt(en)(NO3)(2), a new metal-peptide complex was formed in which …

Shake & Bake: Dual-Use Chemicals, Contexts, And The Illegality Of American White Phosphorus Attacks In Iraq, Joseph D. Tessier Dec 2007

Shake & Bake: Dual-Use Chemicals, Contexts, And The Illegality Of American White Phosphorus Attacks In Iraq, Joseph D. Tessier

The University of New Hampshire Law Review

[Excerpt] “On November 29, 2005, in a Department of Defense press conference with Secretary of Defense Donald Rumsfeld and Gen. Peter Pace, Chairman of the Joint Chiefs of Staff, General Pace stated that white phosphorus “is a legitimate tool of the military,” and can be used for illumination, smoke, and incendiary purposes. Incredibly, the Department of Defense released an addendum to the press conference clarifying that white phosphorus was not used as an incendiary weapon. According to General Pace, “it was well within the law of war to use white phosphorus . . . for marking and screening.” This was …

Methodologies For Automated Microassembly, Mohammad A. Mayyas Dec 2007

Methodologies For Automated Microassembly, Mohammad A. Mayyas

Mechanical and Aerospace Engineering Dissertations - Archive

The development of micromachining technologies has provided wide applications in micro sensing and actuation. However, most of the demonstrated devices are selectively constructed by fabrication processes that are limited to complexity, configuration, dimension, and material variation. The monolithic fabrication has limitations and does not allow the inclusion of multiple components of incompatible processes. Therefore, the construction of 3D microstructures by heterogeneous microassembly is an alternate manufacturing route. In deterministic, monitored or controlled microassembly there has been considerable research in developing, analyzing and applying distributed algorithms for sensor and sensorless based assembly processes. Meso-scale teleoperated work-cells supported by Nano manipulators have …

What Is Rcu, Fundamentally?, Paul E. Mckenney, Jonathan Walpole Dec 2007

What Is Rcu, Fundamentally?, Paul E. Mckenney, Jonathan Walpole

Computer Science Faculty Publications and Presentations

Read-copy update (RCU) is a synchronization mechanism that was added to the Linux kernel in October of 2002. RCU achieves scalability improvements by allowing reads to occur concurrently with updates. In contrast with conventional locking primitives that ensure mutual exclusion among concurrent threads regardless of whether they be readers or updaters, or with reader-writer locks that allow concurrent reads but not in the presence of updates, RCU supports concurrency between a single updater and multiple readers. RCU ensures that reads are coherent by maintaining multiple versions of objects and ensuring that they are not freed up until all pre-existing read-side …

Stochastic Models For In-Silico Event-Based Biological Network Simulation, Preetam Ghosh Dec 2007

Stochastic Models For In-Silico Event-Based Biological Network Simulation, Preetam Ghosh

Computer Science and Engineering Dissertations - Archive

The multi-scale biological system model is a new research direction to capture the dynamic measurements of complex biological systems. The current statistical thermodynamic models can not scale to this challenge due to the explosion of state-spaces of the system, where a biological organ may have billions of cells, each with millions of molecule types and each type may have a few million molecules. We seek to propose a phenomenological theory that will require a smaller number of state variables to address this multi-scaling problem. Discrete Markov statistical process is used to understand the system dynamics in the networking community for …

Sequence To Topography Relationship In Membrane-Inserted Hydrophobic Helics, Shyam S. Krishnakumar Dec 2007

Sequence To Topography Relationship In Membrane-Inserted Hydrophobic Helics, Shyam S. Krishnakumar

Stony Brook Theses and Dissertations Collection, 2006-2020 (closed to submissions)

Hydrophobic α-helices have been widely used to study membrane protein sequencestructure relationships in model membranes. Our lab has developed fluorescence methods to determine the topography of membrane-inserted hydrophobic helices, and to understand the equilibria describing their topographic stability. Using this model membrane system, the minimum hydrophobic length necessary to form a transmembrane (TM) helix in membranes was investigated. Sequences with 13 consecutive hydrophobic residues were found to be the minimum necessary to form a predominantly TM state in a bilayer with a biologically relevant width. The ability of these short hydrophobic sequences to form TM helices in the presence of …

Molecules That Target Beta-Amyloid, Cliff I. Stains, Kalyani Mondal, Indraneel Ghosh Dec 2007

Molecules That Target Beta-Amyloid, Cliff I. Stains, Kalyani Mondal, Indraneel Ghosh

Cliff Stains Publications

The devastating effects of Alzheimer’s and related amyloidogenic diseases have inspired the synthesis and evaluation of numerous ligands to understand the molecular mechanism of the aggregation of the beta-amyloid peptide. Our review focuses on the current knowledge in this field with respect to molecules that have been demonstrated to interact with either oligomeric or fibrillar forms of the beta-amyloid peptide. We describe natural proteins, peptides, peptidomimetics, and small molecules that have been found to interfere with beta-amyloid aggregation. We also detail recent efforts in selecting molecules that target beta-amyloid isolated from antibody, protein, and peptide libraries. These new molecules will …

Corporate Social Responsibility: The Role Of Law And Markets And The Case Of Developing Countries, Antonio Vives Dec 2007

Corporate Social Responsibility: The Role Of Law And Markets And The Case Of Developing Countries, Antonio Vives

Chicago-Kent Law Review

In order for the corporation to engage in responsible practices, many obstacles must be overcome. One such obstacle is the belief of many managers that the corporation would be violating its fiduciary responsibility if it engaged in activities that go beyond what is required by the law. Another obstacle is that many of those practices have a real cost but are perceived not to have a corresponding tangible benefit. The article discusses and dismisses these perceived obstacles and argues that it is both through law and the workings of the market that responsible behavior can enhance society's welfare. It is …

Ral Interacting Protein (Ralbp1): Linking Glutathione Conjugate Transport To Oxidative Stress Defenses And Signaling Pathways, Dilki Wickramarachchi Dec 2007

Ral Interacting Protein (Ralbp1): Linking Glutathione Conjugate Transport To Oxidative Stress Defenses And Signaling Pathways, Dilki Wickramarachchi

Chemistry & Biochemistry Dissertations - Archive

The glutathione-conjugate transporter protein DNP-SG ATPase was demonstrated to be identical to the independently cloned Ral-effector, Ralbp1. Glutathione-conjugate transport is linked to substrate-stimulated ATPase activity, while GTPase stimulating activity (GAP-activity), and clathrin-coated pit-binding activity was demonstrated for this protein by different groups of investigators. The relationship between these activities and physiological functions of Ralbp1 were not clear. The present studies were designed to address the hypothesis that the ability of Ralbp1 to couple the hydrolysis of ATP with the movement of substances, i.e. its transport activity, is the crucial element that allows Ralbp1 to function as a stress-defense protein. Results …

Chemistry & Biochemistry Theses - Archive

The work presented in this thesis focuses on the development of an enantioselective and practical route form the total synthesis of villagorgin via haplosleridamine imidazole alkaloid containing β- carboline moiety by employing the well-known Pictet-Spengler and Fischer indole reactions. We approached two different ways inorder to synthesize these molecules Our first approach focused on using a Dieckmann condensation, requiring the preparation of the corresponding diester. Initial attempts to prepare this substrate directly from histidine were unsuccessful, however after conversion to the N-benzzylamine and reductive amination with ester provided the key diester compound. Unfortunately, attempts to effect the Dieckmann reaction were …

Uniform Weighted Compact / Non-Compact Schemes For Shock / Boundary Layer Interaction, Peng Xie Dec 2007

Uniform Weighted Compact / Non-Compact Schemes For Shock / Boundary Layer Interaction, Peng Xie

Mathematics Dissertations - Archive

The critical problem of CFD is perhaps an accurate approximation of derivatives for a given discrete data set. Based on our previous work on the weighted compact scheme (WCS), a uniform weighted compact / non-compact scheme (UWCNC) has been developed. Similar to WENO, three high order candidates, left, right, and central, are constructed by using Hermite polynomials. According to the smoothness, three weights are derived and assigned to each candidate. The weights will lead the scheme to be upwind-biased when approaching the shock or other discontinuities but quickly becomes central, compact, and of high order just off the shock. Therefore, …

Learning Video Preferences Using Visual Features And Closed Captions, Darin Brezeale Dec 2007

Learning Video Preferences Using Visual Features And Closed Captions, Darin Brezeale

Computer Science and Engineering Dissertations - Archive

Viewers of video now have more choices than ever. As the number of choices increases, the task of searching through these choices to locate video of interest is becoming more difficult. Current methods for learning a viewer's preferences in order to automate the search process rely either on video having content descriptions or on having been rated by other viewers identified as being similar. However, much video exists that does not meet these requirements. To address this need, we use hidden Markov models to learn the preferences of a viewer by combining visual features and closed captions. We validate our …

Beetles For Breakfast: What The Fda Should Be Telling You, Kaycee L. Wolf Dec 2007

Beetles For Breakfast: What The Fda Should Be Telling You, Kaycee L. Wolf

Journal of Food Law & Policy

Imagine sitting down to breakfast and eating strawberry yogurt with a glass of grapefruit juice. You think you are eating a healthy meal, but along with vitamins, calcium, and nutrients, you are getting a side of crushed beetles. Cochineal extract and carmine, two color additives derived from the cochineal beetle, color many foods such as strawberry yogurt. When people consume products with color additives, most do not realize that they could be ingesting insects, which can also be potentially dangerous, not to mention possibly unappetizing or upsetting. Imagine that one minute you are sitting down to eat a healthy cup …
