Age-Specific Differences in Oncogenic Pathway Deregulation Seen in Human Breast Tumors

Anders, Carey K.; Hsu, David; Marcom, Kelly; Blackwell, Kimberly; Potti, Anil (PUBLIC LIBRARY SCIENCE, 2008)

Purpose. To define the biology driving the aggressive nature of breast cancer arising in young women. Experimental Design. Among 784 patients with early stage breast cancer, using prospectively-defined, age-specific cohorts ...
Bayes and Empirical-Bayes Multiplicity Adjustment in the Variable-Selection Problem

Berger, James (INST MATHEMATICAL STATISTICS, 2010)

This paper studies the multiplicity-correction effect of standard Bayesian variable-selection priors in linear regression. Our first goal is to clarify when, and how, multiplicity correction happens automatically in Bayesian ...
Influence of Acellular Natural Lung Matrix on Murine Embryonic Stem Cell Differentiation and Tissue Formation

Wang, Jennifer (MARY ANN LIEBERT INC, 2010)

We report here the first attempt to produce and use whole acellular (AC) lung as a matrix to support development of engineered lung tissue from murine embryonic stem cells (mESCs). We compared the influence of AC lung, ...
Innovation in Business Groups

Belenzon, Prof Sharon (INFORMS, 2010)

Using novel data on European firms, this paper investigates the relationship between business groups and innovation. Controlling for various firm characteristics, we find that group affiliates are more innovative than ...
Low Demographic Variability in Wild Primate Populations: Fitness Impacts of Variation, Covariation, and Serial Correlation in Vital Rates

Morris, William; Alberts, Susan (UNIV CHICAGO PRESS, 2011)

In a stochastic environment, long-term fitness can be influenced by variation, covariation, and serial correlation in vital rates (survival and fertility). Yet no study of an animal population has parsed the contributions ...
Orthogonal Orientation Control of Carbon Nanotube Growth

Zhou, Weiwei; Ding, Lei; Yang, Sungwoo; Liu, Jie (AMER CHEMICAL SOC, 2010)

Carbon nanotubes (CNTs) have attracted attention for their remarkable electrical properties and have being explored as one of the best building blocks in nano-electronics. A key challenge to realize such potential is the ...
Piezopotential Gated Nanowire-Nanotube Hybrid Field-Effect Transistor

Ding, Lei; Liu, Jie (AMER CHEMICAL SOC, 2010)

We report the First piezoelectric potential gated hybrid held-effect transistors based on nanotubes and nanowires. The device consists of single-walled carbon nanotubes (SWNTs) on the bottom and crossed ZnO piezoelectric ...
Traditional and microirrigation with stochastic soil moisture

Vico, Giulia; Porporato, Amilcare (AMER GEOPHYSICAL UNION, 2010)

Achieving a sustainable use of water resources, in view of the increased food and biofuel demand and possible climate change, will require optimizing irrigation, a highly nontrivial task given the unpredictability of ...
Viscous State Effect on the Activity of Fe Nanocatalysts

Curtarolo, Stefano (AMER CHEMICAL SOC, 2010)

Many applications of nanotubes and nanowires require controlled bottom up engineering of these nanostructures In catalytic chemical vapor deposition, the thermo kinetic state of the nanocatalysts near the melting point is ...
