Cosmic Shear Of The Microwave Background: The Curl Diagnostic, Asantha Cooray, Marc Kamionkowski, Robert R. Caldwell

Dartmouth Scholarship

Weak-lensing distortions of the cosmic-microwave-background (CMB) temperature and polarization patterns can reveal important clues to the intervening large-scale structure. The effect of lensing is to deflect the primary temperature and polarization signal to slightly different locations on the sky. Deflections due to density fluctuations, gradient-type for the gradient of the projected gravitational potential, give a direct measure of the mass distribution. Curl-type deflections can be induced by, for example, a primordial background of gravitational waves from inflation or by second-order effects related to lensing by density perturbations. Whereas gradient-type deflections are expected to dominate, we show that curl-type deflections can …

The Cell Cycle–Regulated Genes Of Schizosaccharomyces Pombe, Anna Oliva, Adan Rosebrock, Francisco Ferrezuelo, Haiying Chen, Saumyadipta Pyne, Steve Skiena, Bruce Futcher, Janet Leatherwood

Department of Molecular Genetics and Microbiology Faculty Publications

Many genes are regulated as an innate part of the eukaryotic cell cycle, and a complex transcriptional network helps enable the cyclic behavior of dividing cells. This transcriptional network has been studied in Saccharomyces cerevisiae (budding yeast) and elsewhere. To provide more perspective on these regulatory mechanisms, we have used microarrays to measure gene expression through the cell cycle of Schizosaccharomyces pombe (fission yeast). The 750 genes with the most significant oscillations were identified and analyzed. There were two broad waves of cell cycle transcription, one in early/mid G2 phase, and the other near the G2/M transition. The early/mid G2 …

Soft-Gluon Expansions Through Nnnlo, Nikolaos Kidonakis

Faculty Articles

I present universal master formulas for soft-gluon corrections to hard-scattering cross sections through next-to-next-to-next-to-leading order (NNNLO). I also briefly discuss applications to some processes where these corrections enhance the cross section and decrease the scale dependence.

A Pam Decomposition Of Weak Cpm, Mason B. Wardle

Theses and Dissertations

The Enhanced Flight Termination System uses weak CPM as its modulation scheme and a limiter-discriminator as its demodulation scheme. A PAM representation of weak CPM was developed which representation provided the necessary componenents to build a simplified PAM-based receiver that outperformed the EFTS limiter-discriminator, even in the presence of phase noise. The PAM representation also provided a new perspective into the negative characteristics of weak CPM.

Model-Based Networked Control For Finite-Time Stability Of Nonlinear Systems: The Stochastic Case, Chaouki T. Abdallah, S. Mastellone, P. Dorato

Electrical & Computer Engineering Faculty Publications

In this paper we analyze model-based networked control systems for a discrete-time nonlinear plant model, operating in the presence of stochastic dropout of state observations. The dropout is modeled as a Markov chain, and sufficient conditions for finite-time stochastic stability are provided using the stochastic version of Lyapunov second method. In a companion paper we model the dropout as a deterministic sequence.

The dropout is modeled using communication network dynamics, and sufficient conditions for finite-time stability are provided. In a companion paper we model the dropout as a stochastic sequence.

Moral Intelligence: Mind, Brain An The Law , Atahualpa Fernandez

ExpressO

This paper discusses several issues at the impact of cognitive neuroscience have to do with the current theoretical and methodological edifice of juridical science. Localizing the brain correlates related to moral judgments, using neuroimage techniques (and also studies on brain lesions), seems to be, without doubt, one of the big events in the history of the normative social sciences.The best neuroscientific model of normative judgment available today establishes that the ethical-cerebral law operator counts on, in his neural evaluative-affective systems, a permanent presence of requirements, obligations and strategies, with a “should be” that incorporates internally rational and emotional reasons, that …

Nanoscale Polarization Relaxation In A Polycrystalline Ferroelectric Thin Film: Role Of Local Environments, V. Nagarajan, S. Aggarwal, Alexei Gruverman, R. Ramesh, R. Waser

Alexei Gruverman Publications

In this letter, we report on the study of nanoscale polarization relaxation phenomena in polycrystalline PbZr_0.4Ti_0.6O₃ films. Piezoresponse force microscopy (PFM) images of the as-grown sample reveal grains with a range of contrast, from fully white to gray to fully black. It is shown that this local change in the contrast (magnitude) of the piezoresponse from grain to grain can be attributed to the crystallographic orientation within each grain. PFM-based relaxation experiments show that the rate of relaxation is different for each grain, furthermore it is strongly dependent on the tilt of individual crystallographic orientation …

Giant Electroresistance In Ferroelectric Tunnel Junctions, Mikhail Y. Zhuravlev, Renat F. Sabirianov, Sitaram Jaswal, Evgeny Y. Tsymbal

Physics Faculty Publications

The interplay between the electron transport in metal-ferroelectric-metal junctions with ultrathin ferroelectric barriers and the polarization state of a barrier is investigated. Using a model which takes into account screening of polarization charges in metallic electrodes and direct quantum tunneling across a ferroelectric barrier, we calculate the change in the tunneling conductance associated with the polarization switching. We find the conductance change of a few orders of magnitude for metallic electrodes with significantly different screening lengths. This giant electroresistance effect is the consequence of a different potential profile seen by transport electrons for the two opposite polarization orientations.

Upper Mantle Reflectivity Beneath An Intracratonic Basin: Insights Into The Behavior Of The Mantle Beneath Illinois Basin., Maxwell Sunday Okure

Theses and Dissertations

Reflectivity images of the lower crust and uppermost mantle beneath the Illinois basin have been derived from reprocessing of several hundred kilometers of industry seismic reflection data using extended vibroseis recorrelation. The recorrelation was based on extending an originally 4-s correlated record, acquired with a 16-s sweep from 14 to 126 Hz, to the absolute limit of the full 20 s (~70 km) listening travel time. The reconstructed bandwidth includes frequency components suitable for imaging structures from signals received from both sedimentary basin reflectors and those received from reflectors in the deep crust and upper mantle. Mantle and sub-Moho reflectors …

A Mechanistic Latent Variable Model For Estimating Drug Concentrations In The Male Genital Tract, Leena Choi, Brian Caffo, Charles A. Rohde, Themba T. Ndovi, Craig W. Hendrix

Johns Hopkins University, Dept. of Biostatistics Working Papers

The purpose of this study is to develop statistical methodology to facilitate indirect estimation of the concentration of antiretroviral drugs and viral loads in the prostate gland and the seminal vesicle. The differences in antiretroviral drug concentrations in these organs may lead to suboptimal concentrations in one gland compared to the other. Suboptimal levels of the antiretroviral drugs will not be able to fully suppress the virus in that gland, lead to a source of sexually transmissible virus and increase the chance of selecting for drug resistant virus. This information may be useful selecting antiretroviral drug regimen that will achieve …

A Study Examining The Effect Of Multi-Sensory Stimulation On The Descriptive Writing Of Fourth Grade Students, Karen L. Scott

Theses and Dissertations

The purpose of this study was to determine if multi-sensory stimulation during writing exercises would increase the number of descriptive elements used by fourth grade students. Thirty-five students in two intact classrooms participated in the nonequivalent control group design study. A learning styles questionnaire was administered to both groups to ensure that all modality preferences were represented in each classroom. Two pretests in the form of writing prompts were given to each group. Two weeks later posttests identical to the pretests were administered to each group. During posttest writing exercises, the experimental group was exposed to multi-sensory stimulation. The control …

Predicting On-Orbit Seu Rates, Keith S. Morgan, Michael J. Wirthlin

Faculty Publications

As process geometry sizes continue to decrease, microelectronics are becoming more vulnerable to the effects of radiation. Of particular concern are the effects of Single-Event Upsets (SEU) in Field Programmable Gate Arrays (FPGA). An SEU causes a dynamic memory element, such as a flip-flop or latch, to unwantedly change state. Since FPGAs are becoming an increasingly attractive solution for space system electronics, it is desirable to predict static on-orbit SEU rates likely to be encountered by a particular device for any particular orbit. Mean Time Between Failure (MTBF) can directly be calculated from a static SEU rate, allowing a system …

A Brief Essay On The Importance Of Time In International Conventions On Intellectual Property Rights, Vincenzo Vinciguerra

ExpressO

The paper is a philosophical essay on the manner in which time is conceived and manipulated in four international treaties, namely the Paris Convention, the Patent Cooperation Treaty, the Madrid Agreement/Protocol, and the Berne Convention. In particular, the paper discusses the competing concepts of time as linear or circular, and how the treaties sometimes displace a linear concept of time in order to achieve specific goals.

Neuronomics And Rationality, Terrence Chorvat, Kevin Mccabe

George Mason University School of Law Working Papers Series

The assumption of rationality is both one of the most important and most controversial assumptions of modern economics. This article discusses what current experimental economic as well as neuroscience research tells us about the relationship between rationality and the mechanisms of human decision-making. The article explores the meaning of rationality, with a discussion of the distinction between traditional constructivist rationality and more ecological concepts of rationality. The article argues that ecological notions of rationality more accurately describe both human neural mechanisms as well as a wider variety of human behavior than do constructivist notions of rationality.

A Partial Likelihood For Spatio-Temporal Point Processes, Peter J. Diggle

Johns Hopkins University, Dept. of Biostatistics Working Papers

Spatio-temporal point process data arise in many fields of application. An intuitively natural way to specify a model for a spatio-temporal point process is through its conditional intensity at location x and time t, given the history of the process up to time t. Typically, this results in an analytically intractable likelihood. Likelihood-based inference therefore relies on Monte Carlo methods which are computationally intensive and require careful tuning to each application. We propose a partial likelihood alternative which is computationally straightforward and can be applied routinely. We apply the method to data from the 2001 foot-and-mouth epidemic in the UK, …
