Proliferation-Dependent Alterations of the DNA Methylation Landscape Underlie Hematopoietic Stem Cell Aging
(Elsevier BV, 2013)The functional potential of hematopoietic stem cells (HSCs) declines during aging, and in doing so, significantly contributes to hematopoietic pathophysiology in the elderly. To explore the relationship between age-associated ... -
Proliferative and Transcriptional Identity of Distinct Classes of Neural Precursors in the Mammalian Olfactory Epithelium
(Company of Biologists, 2010)Neural precursors in the developing olfactory epithelium (OE) give rise to three major neuronal classes – olfactory receptor (ORNs), vomeronasal (VRNs) and gonadotropin releasing hormone (GnRH) neurons. Nevertheless, the ... -

The Promises and Pitfalls of Genoeconomics
(Annual Reviews, 2012)This article reviews existing research at the intersection of genetics and economics, presents some new findings that illustrate the state of genoeconomics research, and surveys the prospects of this emerging field. Twin ... -
Promoter decoding of transcription factor dynamics involves a trade-off between noise and control of gene expression
(Wiley-Blackwell, 2013)Numerous transcription factors (TFs) encode information about upstream signals in the dynamics of their activation, but how downstream genes decode these dynamics remains poorly understood. Using microfluidics to control ... -
Promoting equality for ethnic minority NHS staff—what works?
(BMJ Publishing Group Ltd., 2015)NHS organisations are now being judged on indicators of ethnic diversity. Naomi Priest and colleagues look at the international evidence on how they should tackle discrimination -
Promoting Youth Self-Regulation through Psychotherapy: Redesigning Treatments to Fit Complex Youth in Clinical Care
(2015)Improving self-regulation can be seen as a central objective of youth psychotherapy. Five decades of psychotherapy research have produced an array of evidence-based psychotherapies (EBPs), but meta-analyses have shown that ... -
Promotion of Mn(II) Oxidation and Remediation of Coal Mine Drainage in Passive Treatment Systems by Diverse Fungal and Bacterial Communities
(American Society for Microbiology, 2010)Biologically active, passive treatment systems are commonly employed for removing high concentrations of dissolved Mn(II) from coal mine drainage (CMD). Studies of microbial communities contributing to Mn attenuation through ... -
Prompt decays of general neutralino NLSPs at the Tevatron
(Springer Science + Business Media, 2010)Recent theoretical developments have shown that gauge mediation has a much larger parameter space of possible spectra and mixings than previously considered. Motivated by this, we explore the collider phenomenology of gauge ... -
Prompt Radiation and Mass Outflows From the Stream–stream Collisions of Tidal Disruption Events
(American Astronomical Society, 2016)Stream-stream collisions play an important role for the circularization of highly eccentric streams resulting from tidal disruption events (TDEs). We perform three dimensional radiation hydrodynamic simulations to show ... -
Prompt tidal disruption of stars as an electromagnetic signature of supermassive black hole coalescence
(Oxford University Press, 2011)A precise electromagnetic measurement of the sky coordinates and redshift of a coalescing black hole binary holds the key for using its gravitational wave (GW) signal to constrain cosmological parameters and to test general ... -

Propensity score methods for creating covariate balance in observational studies
(Elsevier BV, 2011)Randomization of treatment assignment in experiments generates treatment groups with approximately balanced baseline covariates. However, in observational studies, where treatment assignment is not random, patients in the ... -
Proper and Common Nouns: Form Class Judgments in Broca's Aphasia
(Elsevier BV, 1986)Studies of agrammatic Broca's aphasics' comprehension of sentences containing articles have demonstrated profound deficits. It has not been clear whether the impairments are due to an inability to isolate the article in ... -
Proper Motion of Water Masers Associated with IRAS 21391+5802: Bipolar Outflow and an AU‐Scale Dusty Circumstellar Shell
(IOP Publishing, 2000)We present VLBA observations of water maser emission associated with the star forming region IRAS 21391+5802, which is embedded in a bright rimmed cometary globule in IC1396. The angular resolution of the maps is ∼ 0.8 ... -

The Proper Scope of Government: Theory and an Application to Prisons
(Oxford University Press (OUP), 1997)When should a government provide a service inhouse and when should it contract out provision? We develop a model in which the provider can invest in improving the quality of service or reducing cost, If contracts are ... -
Properties and detection of spin nematic order in strongly correlated electron systems
(IOP Publishing, 2005)A spin nematic is a state which breaks spin SU(2) symmetry while preserving translational and time reversal symmetries. Spin nematic order can arise naturally from charge fluctuations of a spin stripe state. Focusing on ... -
Properties of copper (fluoro-)phthalocyanine layers deposited on epitaxial graphene
(AIP Publishing, 2011)We investigate the atomic structure and electronic properties of monolayers of copper phthalocyanines (CuPc) deposited on epitaxial graphene substrate. We focus in particular on hexadecafluorophthalocyanine (F16CuPc), using ...
