Mid-Infrared Spectroscopy of High-Redshift 3crr Sources
(IOP Publishing, 2010)Using the Spitzer Space Telescope, we have obtained rest-frame 9–16 μm spectra of 11 quasars and 9 radio galaxies from the 3CRR catalog at redshifts 1.0 <z< 1.4. This complete flux-limited 178 MHz selected sample is unbiased ... -
Mid-Infrared-Selected Quasars. I. Virial Black Hole Mass and Eddington Ratios
(IOP Publishing, 2014)We provide a catalog of 391 mid-infrared-selected (MIR; 24 μm) broad-emission-line (BEL; type 1) quasars in the 22 deg2 SWIRE Lockman Hole field. This quasar sample is selected in the MIR from Spitzer MIPS with S 24 > 400 ... -
Mid-Level Features Elicit Cognitive and Neural Representations of Object Size
(2017-05-15)Most models of object recognition assume that we first recognize objects at the basic-level (e.g., as a “cup”), and then that the resulting object representations act as pointers that allow us to access knowledge about ... -
Mid-level perceptual features distinguish objects of different real-world sizes.
(American Psychological Association (APA), 2016)Understanding how perceptual and conceptual representations are connected is a fundamental goal of cognitive science. Here, we focus on a broad conceptual distinction that constrains how we interact with objects—real-world ... -
Mid-Pliocene shorelines of the US Atlantic Coastal Plain — An improved elevation database with comparison to Earth model predictions
(Elsevier, 2015)For nearly a century, the Atlantic Coastal Plain (ACP) of the United States has been the focus of studies investigating Pliocene and Pleistocene shorelines, however, the mapping of paleoshorelines was primarily done by ... -
Midbrain dopamine neurons signal aversion in a reward-context-dependent manner
(eLife Sciences Publications, Ltd, 2016)Dopamine is thought to regulate learning from appetitive and aversive events. Here we examined how optogenetically-identified dopamine neurons in the lateral ventral tegmental area of mice respond to aversive events in ... -
Middle and Late Cambrian Sponge Spicules from Hunan, China
(Society of Economic Paleontologists and Mineralogists, 1996)Abundant and well-preserved assemblages of disarticulated sponge spicules occur in Middle and Late Cambrian platform carbonates of western Hunan, China. Assemblages recovered from 11 stratigraphic horizons include calcisponges, ... -
Middle Cranial Fossa Anatomy and the Origin of Modern Humans
(Wiley-Blackwell, 2008)Anatomically, modern humans differ from archaic forms in possessing a globular neurocranium and a retracted face and in cognitive functions, many of which are associated with the temporal lobes. The middle cranial fossa ... -
Middle Proterozoic Ocean Chemistry: Evidence from the McArthur Basin, Northern Australia
(Kline Geology Laboratory, Yale University, 2002)We report on the iron-sulfur systematics and S-isotopic compositions of upper Paleoproterozoic carbonaceous shales from the Wollogorang and lower Reward formations, McArthur Basin, northern Australia. Iron speciation in ... -
Middle School Math Acceleration and Equitable Access to 8th Grade Algebra: Evidence from the Wake County Public School System
(Harvard Kennedy School, Harvard University, 2014)School districts across the country have struggled to increase the proportion of students taking algebra by 8th grade, thought to be an important milestone on the pathway to college preparedness. We highlight key features ... -
Middle-Class Politics and the Neoliberalization of Copper Mining in Pinochet-era Chile
(2021-07-12)This dissertation analyzes the development of labor relations and class politics in Chile’s large-scale copper industry between the 1970s and 1990s. It follows a generation of copper miners who fought to bring the copper ... -
Middle-Period Discourse on the Zhong Guo: The Central Country
(Han Xue Yan Jiu Zhong Xin (漢學研究中心), 2009)English: During the middle period (8th - 15th century) literati began to discuss Zhong guo as both historical place and as culture. Although such writing made a clear distinction between Zhong guo as the central and superior ... -
Middlebrow Modernism: Britten's Operas and the Great Divide
(2013-10-18)This study examines the way Britten's operas and their audiences muddied the waters of the so-called "great divide" between modernism and mass culture, mediating between the aesthetics of difficulty and distinction on the ... -
Midinfrared electroluminescence in quantum cascade structures with InP/InGaAs active regions
(AIP Publishing, 2003)We report on the midinfrared emission from electroluminescent devices with quantum cascade active regions based on InGaAs/InP heterostructures. We observe emission at lambdasimilar to12 mum from two different structures ... -
A Midlatitude–ENSO Teleconnection Mechanism via Baroclinically Unstable Long Rossby Waves
(American Meteorological Society, 2003)The possibility of generating decadal ENSO variability via an ocean teleconnection to the midlatitude Pacific is studied. This is done by analyzing the sensitivity of the equatorial stratification to midlatitude processes ... -
Mid‐Infrared and Visible Photometry of Galaxies: Anomalously Low Polycyclic Aromatic Hydrocarbon Emission from Low‐Luminosity Galaxies
(IOP Publishing, 2005)The Spitzer Space Telescope First Look Survey Infrared Array Camera (IRAC) near- and mid-infrared imaging data partially overlap the Sloan Digital Sky Survey (SDSS), with 313 visible-selected (r < 17.6 mag) SDSS main sample ... -
Migrant Networks
(Wiley, 2015)Migrant networks—webs of social ties between migrants in destination and individuals in origin—are a key determinant of the magnitude and direction of migration flows, as well as migrants’ adaptation outcomes. The increasing ... -
Migration and the Making of Cultural Landscapes in Medieval Anatolia: a Eurasian Regional Perspective from Inner Pontus
(2021-11-16)Different communities of medieval Anatolia lived in different worlds while inhabiting the same physical grounds. Focusing on a small region – the valley of the Iris River around modern Turkish cities of Niksar, Tokat, and ... -
