Magnetically tunable self-assembly of colloidal rings

Li, Kwan H.; Yellen, Benjamin B. (AMER INST PHYSICS, 2010)

We present a technique using ferrofluid to induce bidisperse suspensions of superparamagnetic and diamagnetic beads to assemble into colloidal ring configurations. The separation distance between particles within the ring ...
Magnetic levitation of metamaterial bodies enhanced with magnetostatic surface resonances

Urzhumov, Yaroslav A.; Chen, Wenchen; Bingham, Chris; Padilla, Willie; Smith, David R. (American Physical Society, 2012-02-27)

We propose that macroscopic objects built from negative-permeability metamaterials may experience resonantly enhanced magnetic force in low-frequency magnetic fields. Resonant enhancement of the timeaveraged force originates ...
Magnetic Resonance Water Proton Relaxation in Protein Solutions and Tissue: T-1p Dispersion Characterization

Chen, Enn-Ling; Kim, Raymond (PUBLIC LIBRARY SCIENCE, 2010)

Background: Image contrast in clinical MRI is often determined by differences in tissue water proton relaxation behavior. However, many aspects of water proton relaxation in complex biological media, such as protein solutions ...
Magnetic superlens-enhanced inductive coupling for wireless power transfer

Huang, Da; Urzhumov, Yaroslav A.; Smith, David R.; Teo, Koon Hoo; Zhang, Jinyun (American Institute of Physics, 2012-03-20)

We investigate numerically the use of a negative-permeability “perfect lens” for enhancing wireless power transfer between two current carrying coils. The negative permeability slab serves to focus the flux generated in ...
Magnitude and Breadth of a Nonprotective Neutralizing Antibody Response in an Efficacy Trial of a Candidate HIV-1 gp120 Vaccine

Montefiori, David (UNIV CHICAGO PRESS, 2010)

Background. A candidate vaccine consisting of human immunodeficiency virus type 1 (HIV-1) subunit gp120 protein was found previously to be nonprotective in an efficacy trial (Vax004) despite strong antibody responses against ...
Major and minor music compared to excited and subdued speech

Bowling, Daniel L. (ACOUSTICAL SOC AMER AMER INST PHYSICS, 2010)

The affective impact of music arises from a variety of factors, including intensity, tempo, rhythm, and tonal relationships. The emotional coloring evoked by intensity, tempo, and rhythm appears to arise from association ...
Making Marine Life Count: A New Baseline for Policy

Halpin, Patrick (PUBLIC LIBRARY SCIENCE, 2010)
Making sense of health information technology implementation: A qualitative study protocol

Kitzmiller, Rebecca R.; Anderson, Ruth (BIOMED CENTRAL LTD, 2010)

Background: Implementing new practices, such as health information technology (HIT), is often difficult due to the disruption of the highly coordinated, interdependent processes (e. g., information exchange, communication, ...
Making Up History: A Comment on Pratten

Weintraub, E Roy (SSRN eLibrary, 2004)

atten's critique of mathematical formalism in the discipline of economics does not provide an adequate definition of formalism and his use of the term bears little resemblance to common mathematical usage. Furthermore, ...
Male tenure and reproductive success in a one-male vs. a multi-male group in free-ranging Howling Monkeys in Costa Rica

Clarke, MR; Glander, KE (2005)
Management of adolescents and adults with febrile illness in resource limited areas

Crump, John Andrew (BMJ Publishing Group, 2011)

Overlap in the clinical features of febrile illnesses and limited laboratory services make the management of febrile patients in resource limited settings challenging WHO guidelines for managing febrile adolescents ...
Managerial and Stockholder Welfare Models of Firm Expenditures

Grabowski, Henry; Dennis Mueller (1972-02)
Managing and Transforming Water Conflicts

Weinthal, Erika (M I T PRESS, 2010)
Managing Dynamic Competition

Lewis, Tracy; Yildirim, Huseyin (American Economic Review, 2002)

In many important high-technology markets, including software development, data processing, communications, aeronautics, and defense, suppliers learn through experience how to provide better service at lower cost. This ...
Managing Public Affairs Records in the Digital Age

Pyatt, Timothy D. (Society of American Archivists, 2008-04)

Public Affairs operations at institutions of higher education are rapidly abandoning paper as a medium for disseminating press releases, news stories, and campus promotional materials. Archives must develop plans to ...
Managing Switching Costs in Multiperiod Procurements with Strategic Buyers

Lewis, Tracy; Yildirim, Huseyin (SSRN eLibrary, 2005)

This article examines the use of switching costs by long-lived strategic buyers to manage dynamic competition between rival suppliers. The analysis reveals how buyers may employ switching costs to their advantage. We show ...
Man's search for meaning: The case of Legos

Ariely, Dan (Elsevier, 2008-09)

We investigate how perceived meaning influences labor supply. In a laboratory setting, we manipulate the perceived meaning of simple, repetitive tasks and find a strong influence on subjects’ labor supply. Despite the fact ...
A MAN WITH NO RELIGION

Strandberg, Victor (2008)
A Man with No Religion

Strandberg, Victor (2012-02-06)
Mapping the complexity of transcription control in higher eukaryotes

Ohler, Uwe (BIOMED CENTRAL LTD, 2010)

Recent genomic analyses suggest the importance of combinatorial regulation by broadly expressed transcription factors rather than expression domains characterized by highly specific factors.
