( 2007-03-23 )Ka x-ray emission, extreme ultraviolet emission, and plasma imaging techniques have been used to diagnose energy transport patterns in copper foils ranging in thickness from 5 to 75 µm for intensities up to 5×10^20 W ... -
Measuring the Remnant Mass Function of the Galactic Bulge
Gould, Andrew ( 2000-06-01 )I show that by observing microlensing events both astrometrically and photometrically, the Space Interferometry Mission (SIM) can measure the mass function of stellar remnants in the Galactic bulge, including white dwarfs, ... -
Measuring the Rotation Speed of Giant Stars from Gravitational Microlensing
Gould, Andrew ( 1997-07-01 )During some gravitational lensing events, the lens transits the disk of the star. This event causes a shift in the apparent radial velocity of the star proportional to the star's rotation speed. The magnification of such ... -
Mediastinal abscess after endobronchial ultrasound with transbronchial needle aspiration: a case report
Moffatt-Bruce, Susan D.; Ross, Patrick ( 2010-05-05 )Endobronchial ultrasound (EBUS) with transbronchial needle aspiration is now becoming widely accepted as a preferred staging technique. It has been perceived as a non-invasive and well tolerated procedure with minimal ... -

Melting of Branched RNA Molecules
Bundschuh, Ralf; Bruinsma, Robijn ( 2008-04-07 )In this Letter we show that the melting thermodynamics of RNA molecules is very sensitive to the branching geometry. We find that, when pairing interactions are described by a Gō model, unbranched RNA molecules with a ... -
A method for detecting undervalued resources with application to breeding birds
Shustack, Daniel P.; Rodewald, Amanda D. ( 2010-10 )Anthropogenic changes to ecosystems can decouple habitat selection and quality, a phenomenon well illustrated by ecological traps in which individuals mistakenly prefer low-quality habitats. Less recognized is the possibility ... -
Method to calculate electrical forces acting on a sphere in an electrorheological fluid
Kim, Kwangmoo; Stroud, David; Li, Xiangting; Bergman, David J. ( 2005-03-07 )We describe a method to calculate the electrical force acting on a sphere in a suspension of dielectric spheres in a host with a different dielectric constant, under the assumption that a spatially uniform electric field ... -
A Method to Measure the Ratio of Total to Selective Extinction toward Baade's Window
Gould, Andrew; Stutz, Amelia; Frogel, Jay A. ( 2001-02-01 )We present a method to measure the ratio of total to selective extinction, R_VI ≡ A_V/E(V-I), toward Baade's window by comparing the VIK colors of 146 Baade's window G and K giants from Tiede, Frogel, & Terndrup with the ... -
Methodological Issues in Designing a Multisite Trial of Risperidone in Children and Adolescents with Autism
Scahill, Larry; McCracken, James; McDougle, Christopher J.; Aman, Michael; Arnold, L.

Methods: Review the design considerations for ... -
Methylphenidate Treatment in Children with Borderline IQ and Mental Retardation: Analysis of Three Aggregated Studies
Aman, Michael G.; Buican, Brett; Arnold, L. Eugene ( 2003 )Objective: To determine response of low-IQ children with attention deficit hyperactivity disorder (ADHD) symptoms to methylphenidate (MPH). Methods: An aggregated analysis was conducted in 90 children with low IQ who ... -
Methylphenidate vs. amphetamine: Comparative review
Arnold, L. E. ( 2000 )This article compares the two most common medications for Attention-Deficit/Hyperactivity Disorder (ADHD), using data from controlled studies. Medline and Psychinfo searches were done for 1984-1996 with the key words ... -
Microfinance investments in quality at private clinics in Uganda: a case-control study
Seiber, Eric E.; Robinson, Amara L. ( 2007-10-18 )Background: Small private-sector health care providers can play an important role in meeting the developing country health care needs, but a lack of credit can prove major constraint to small-provider expansion. This ... -
Microlens Parallax Asymmetries toward the Large Magellanic Cloud
Gould, Andrew ( 1998-10-10 )If the microlensing events now being detected toward the Large Magellanic Cloud (LMC) are due to lenses in the Milky Way halo, then the events should typically have asymmetries of order 1% owing to parallax from the reflex ... -
Microlens Parallaxes of Binary Lenses Measured from a Satellite
Graff, David S.; Gould, Andrew ( 2002-11-20 )Caustic-crossing binary lenses make up about 5% of all detected microlenses. The relative proper motion of a caustic-crossing binary lens can be measured with observations from a single terrestrial telescope. Thus, uniquely, ... -
Microlens Parallaxes with SIRTF
Gould, Andrew ( 1999-04-01 )The Space Infrared Telescope Facility (SIRTF) will drift away from the Earth at ~0.1 AU yr^-1. Microlensing events will therefore have different characteristics as seen from the satellite and the Earth. From the difference ... -
