Rauch, Dan; Gross, Shimon; Harding, John; Bokhari, Sirosh; Niewiesk, Stefan; Lairmore, Michael; Piwnica-Worms, David; Ratner, Lee ( 2009-12-17 )Chronic inflammation has long been associated with a wide range of malignancies, is now widely accepted as a risk factor for development of cancer, and has been implicated as a promoter of a variety of cancers including ... -
T2 quantification for improved detection of myocardial edema
Giri, Shivraman; Chung, Yiu C.; Merchant, Ali; Mihai, Georgeta; Rajagopalan, Sanjay; Raman, Subha; Simonetti, Orlando ( 2009-12-30 )BACKGROUND:T2-Weighted (T2W) magnetic resonance imaging (MRI) pulse sequences have been used to detect edema in patients with acute myocardial infarction and differentiate acute from chronic infarction. T2W sequences have ... -

Temperature Fluctuations and Abundances in H II Galaxies
Steigman, Gary; Viegas, Sueli M.; Gruenwald, Ruth ( 1997-11-20 )There is evidence for temperature fluctuations in planetary nebulae and in some Galactic H II regions. If such fluctuations occur in the low-metallicity, extragalactic H II regions used to probe the primordial helium ... -
Territorialization, science and the colonial state: the case of Highway 55 in Minnesota
Wainwright, Joel; Robertson, Morgan ( 2003-04 )This paper examines a recent conflict over the rerouting of Highway 55 in the city of Minneapolis, Minnesota. During a three-year struggle over the project, a group of indigenous people argued that the space where the ... -
A Test of Pre-Main-Sequence Lithium Depletion Models
Yee, Jennifer C.; Jensen, Eric L. N. ( 2010-03-01 )Despite the extensive study of lithium depletion during pre-main-sequence (PMS) contraction, studies of individual stars show discrepancies between ages determined from the Hertzsprung-Russell (H-R) diagram and ages ... -
Testable dark energy predictions from current data
Mortonson, Michael J.; Hu, Wayne; Huterer, Dragan ( 2010-03-22 )Given a class of dark energy models, constraints from one set of cosmic acceleration observables make predictions for other observables. Here we present the allowed ranges for the expansion rate H(z), distances D(z), and ... -
Testing for allergic disease: Parameters considered and test value
Szeinbach, Sheryl L.; Harpe, Spencer E.; Williams, P. Brock; Elhefni, Hanaa ( 2008-08-26 )Background: Test results for allergic disease are especially valuable to allergists and family physicians for clinical evaluation, decisions to treat, and to determine needs for referral. Methods: This study used a ... -
Testing improved staggered fermions with m_s and B_K
Lee, Weonjong; Bhattacharya, Tanmoy; Fleming, George T.; Gupta, Rajan; Kilcup, Gregory; Sharpe, Stephen R. ( 2005-05-02 )We study the improvement of staggered fermions using hypercubically smeared links. We calculate the strange quark mass and the kaon B parameter, B_K, in quenched QCD on a 16^3×64 lattice at β=6.0. We find m_s(MSˉ ... -
Tests for Substructure in Gravitational Lenses
Kochanek, C. S.; Dalal, N. ( 2004-07-20 )The flux anomalies in four-image gravitational lenses can be interpreted as evidence for the dark matter substructure predicted by cold dark matter (CDM) halo models. In principle, these flux anomalies could arise from ... -
TeV Gamma Rays from Geminga and the Origin of the GeV Positron Excess
Yuksel, Hasan; Kistler, Matthew D.; Stanev, Todor ( 2009-07-27 )The Geminga pulsar has long been one of the most intriguing MeV-GeV γ-ray point sources. We examine the implications of the recent Milagro γ-ray Observatory detection of extended, multi-TeV γ-ray emission from Geminga, ... -
Text mining of full-text journal articles combined with gene expression analysis reveals a relationship between sphingosine-1-phosphate and invasiveness of a glioblastoma cell line
Natarajan, Jeyakumar; Berrar, Daniel; Dubitzky, Werner; Hack, Catherine; Zhang, Yonghong; DeSesa, Catherine; Van Brocklyn, James R.; Bremer, Eric G. ( 2006-08-10 )Background: Sphingosine 1-phosphate (S1P), a lysophospholipid, is involved in various cellular processes such as migration, proliferation, and survival. To date, the impact of S1P on human glioblastoma is not fully ... -
Theoretical Fe I-III Emission-Line Strengths from Active Galactic Nuclei with Broad-Line Regions
Nahar, Sultana Nurun; Sigut, T. A. A.; Pradhan, Anil K. ( 2004-08 )We present theoretical iron emission line strengths for physical conditions typical of active galactic nuclei (AGNs) with broad-line regions. The non–local thermodynamic equilibrium (NLTE) models include a new and extensive ... -
Theoretical Models of the Halo Occupation Distribution: Separating Central and Satellite Galaxies
Zheng, Zheng; Berlind, Andreas A.; Weinberg, David H.; Benson, Andrew J.; Baugh, Carlton M.; Cole, Shaun; Davé, Romeel; Frenk, Carlos S.; Katz, Neal; Lacey, Cedric G. ( 2005-11-10 )The halo occupation distribution (HOD) describes the relation between galaxies and dark matter at the level of individual dark matter halos. The properties of galaxies residing at the centers of halos differ from those of ... -
