Potent and broad neutralizing activity of a single chain antibody fragment against cell-free and cell-associated HIV-1

Montefiori, David (LANDES BIOSCIENCE, 2010)

Several human monoclonal antibodies (hmAbs) exhibit relatively potent and broad neutralizing activity against HIV-1, but there has not been much success in using them as potential therapeutics. We have previously hypothesized ...
Potential Impacts of Leakage from Deep CO2 Geosequestration on Overlying Freshwater Aquifers

Little, Mark G.; Jackson, Robert (AMER CHEMICAL SOC, 2010)

Carbon Capture and Storage may use deep saline aquifers for CO2 sequestration, but small CO2 leakage could pose a risk to overlying fresh groundwater. We performed laboratory incubations of CO2 infiltration under oxidizing ...
Potential vorticity dynamics of boundary currents in a quasigeostrophic ocean.

Lozier, Susan; Riser, S.C. (Journal of Physical Oceanography, 1989)

Boundary layer potential vorticity dynamics for a quasi-geostrophic, eddy-resolving general circulation ocean model are studied using both Lagrangian and Eulerian analyses. Active western boundary layers are found not only ...
Practice and Ideology: A Cautionary Note on the Historian's Craft

French, John D. (1991)
Precise pattern of recombination in serotonergic and hypothalamic neurons in a Pdx1-cre transgenic mouse line

Berger, Miles (BIOMED CENTRAL LTD, 2010)

Background: Multicellular organisms are characterized by a remarkable diversity of morphologically distinct and functionally specialized cell types. Transgenic techniques for the manipulation of gene expression in specific ...
Predicting the dry deposition of aerosol-sized particles using layer-resolved canopy and pipe flow analogy models: Role of turbophoresis

Katul, Gaby (AMER GEOPHYSICAL UNION, 2010)

A number of synthesis activities, mathematical modeling, and experiments on dry deposition of aerosol-sized particles over forested surfaces point to three disjointed findings: (1) deposition velocities measured over tall ...
Predicting the Frequency Dispersion of Electronic Hyperpolarizabilities on the Basis of Absorption Data and Thomas-Kuhn Sum Rules

Hu, Xiangqian; Xiao, Dequan; Keinan, Shahar; Therien, Michael; Yang, Weitao; Beratan, David (AMER CHEMICAL SOC, 2010)

Successfully predicting the frequency dispersion of electronic hyperpolarizabilities is an unresolved challenge in materials science and electronic structure theory. We show that the generalized Thomas-Kuhn sum rules, ...
Prediction in Dynamic Models with Time Dependent Conditional Variances

Bollerslev, Tim; Baillie, Richard T. (Journal of Econometrics, 1992)

This paper considers forecasting the conditional mean and variance from a single-equation dynamic model with autocorrelated disturbances following an ARMA process, and innovations with time-dependent conditional ...
Predictions of the Pt8Ti Phase in Unexpected Systems

Taylor, Richard H.; Curtarolo, Stefano (AMER CHEMICAL SOC, 2010)

The binary A(8)B phase (prototype Pt8Ti) has been experimentally observed in 11 systems. A high-throughput search over all the binary transition intermetallics, however, reveals 59 occurrences of the A(8)B phase: Au8Zn ...
Preemption, Divestiture, and Forward Contracting in a Market Dominated by a Single Firm

Lewis, Tracy (The American Economic Review, 1983)

A central concern of industrial organization literature is to determine if markets dominated by a leading producer tend to remain that way when entry by rival firms is possible. In particular, suppose market entry is ...
Pregnancy, Alcohol Intake, and Intimate Partner Violence among Men and Women Attending Drinking Establishments in a Cape Town, South Africa Township

Eaton, Lisa A.; Kalichman, Seth C.; Sikkema, Kathleen J.; Skinner, Donald; Watt, Melissa; Pieterse, Desiree; Pitpitan, Eileen V. (Springer Verlag, 2012-02)

The highest rates of fetal alcohol syndrome worldwide can be found in South Africa. Particularly in impoverished townships in the Western Cape, pregnant women live in environments where alcohol intake during pregnancy has ...
Pregnancy and Virologic Response to Antiretroviral Therapy in South Africa

Westreich, Daniel J (Public Library of Science, 2011-08)

Background Although women of reproductive age are the largest group of HIV-infected individuals in sub-Saharan Africa, little is known about the impact of pregnancy on response to highly active antiretroviral therapy ...
Preliminary-Test Estimation of the Error Variance in Linear Regression

Clarke, Judith A.; Giles, David E. A.; Wallace, Dudley (Econometric Theory, 1987-08)

We derive exact finite-sample expressions for the biases and risks of several common pretest estimators of the scale parameter in the linear regression model. These estimators are associated with least squares, maximum ...
Premodern Shakespeare

Beckwith, Sarah (DUKE UNIV PRESS, 2010)
Prenatal Protease Inhibitor Use and Risk of Preterm Birth among HIV-Infected Women Initiating Antiretroviral Drugs during Pregnancy

Livingston, Elizabeth (UNIV CHICAGO PRESS, 2010)

Background. Conflicting results have been reported among studies of protease inhibitor (PI) use during pregnancy and preterm birth. Uncontrolled confounding by indication may explain some of the differences among studies. ...
Pre-negotiation Public Commitment in Domestic and International Bargaining

Leventoglu, Dr Bahar; Tarar, Ahmer (American Political Science Review, 2005)

We use a formal bargaining model to examine why, in many domestic and international bargaining situations, one or both negotiators make public statements in front of their constituents committing themselves to obtaining ...
Preservation of Beam Emittance in the Presence of Ion Motion in Future High-Energy Plasma-Wakefield-Based Colliders

Katsouleas, Thomas (AMER PHYSICAL SOC, 2010)

The preservation of beam quality in a plasma wakefield accelerator driven by ultrahigh intensity and ultralow emittance beams, characteristic of future particle colliders, is a challenge. The electric field of these beams ...
Prevalence and correlates of clinically significant depressive symptoms among elderly people in Sri Lanka: findings from a national survey

Malhotra, Rahul; Chan, Angelique; Ostbye, Truls (CAMBRIDGE UNIV PRESS, 2010)

Background: Elderly Sri Lankans (11.2%, of the nation's population) have witnessed many years of ethnic conflict, a destructive tsunami and increasing emigration of young adults. However, very little is known about the ...
Prevalence and predictors of giving birth in health facilities in Bugesera District, Rwanda

Ostermann, Jan; Thielman, Nathan Maclyn (BioMed Central, 2012-12)

Background The proportion of births attended by skilled health personnel is one of two indicators used to measure progress towards Millennium Development Goal 5, which aims for a 75% reduction in global maternal mortality ...
