Last-Conjunct Agreement in Slovenian
(Michigan Slavic Publications, 2007) -
'Last-place Aversion': Evidence and Redistributive Implications
(Oxford University Press (OUP), 2014)We present evidence from laboratory experiments showing that individuals are "last-place averse." Participants choose gambles with the potential to move them out of last place that they reject when randomly placed in other ... -
The Late Bronze–Early Iron Transition: Changes in Warriors and Warfare and the Earliest Recorded Naval Battles
(2015)The tumultuous transition from the Late Bronze to the Early Iron Age in the Eastern Mediterranean was marked by a change in the iconography of warriors and warfare, particularly in Egypt and in the Aegean world. It is also ... -
Late Cambrian Radiolaria from Hunan, China
(Society of Economic Paleontologists and Mineralogists, 1997)Well-preserved polycystine radiolarians, representing a new species in the family Entactiniidae, were recovered from subtidal micrites and bioclastic micrites of the Upper Cambrian (<i>Glyptagnostus reticulatus</i> trilobite ... -
Late Ediacaran Redox Stability and Metazoan Evolution
(Elsevier, 2012)The Neoproterozoic arrival of animals fundamentally changed Earth's biological and geochemical trajectory. Since the early description of Ediacaran and Cambrian animal fossils, a vigorous debate has emerged about the drivers ... -
Late First-Row Transition Metals in Weak Ligand Fields - Correlating High-Spin Electronic Structure and Reactivity
(2013-09-16)High spin has been shown to be necessary for optimal reactivity of transition metal complexes toward the activation and functionalization of C-H bonds. This thesis presents our examination of the weak-field, tripodal, ... -
Late Insights into Early Origins of Disease
(Wiley-Blackwell, 2008)Burgeoning research into early functional programming has opened a new perspective of developmental origins of disease and organ dysfunction. In examining the roots of this emerging paradigm, it appears that crucial ... -
Late Na+ current and protracted electrical recovery are critical determinants of the aging myopathy
(Nature Pub. Group, 2015)The aging myopathy manifests itself with diastolic dysfunction and preserved ejection fraction. We raised the possibility that, in a mouse model of physiological aging, defects in electromechanical properties of cardiomyocytes ... -
Late Oligocene and Early Miocene Muroidea of the Zinda Pir Dome
(Taylor & Francis, 2015)A series of Oligocene through Early Miocene terrestrial deposits preserved in the foothills of the Zinda Pir Dome of western Pakistan produce multiple, superposed fossil mammal localities. These include small mammal ... -
Late Pleistocene age and archaeological context for the hominin calvaria from GvJm-22 (Lukenya Hill, Kenya)
(Proceedings of the National Academy of Sciences, 2015)The KNM-LH 1 Homo sapiens partial calvaria from site GvJm-22 at Lukenya Hill, Kenya, is a securely dated fossil hominin associated with Late Pleistocene-aged Later Stone Age archaeological deposits from eastern Africa, a ... -
The Late Soviet and Post-Soviet Ephemera Collection at Harvard Library
(Informa UK Limited, 2021-04-25)The Russian Ephemera Collection (late 1980s-1990s) at Harvard Library is a monumental primary source collection for the study of the late Soviet and post-Soviet era. It was acquired in the 1990s along with the collection ... -
Late Spectral Evolution of the Ejecta and Reverse Shock in Sn 1987a
(American Astronomical Society, 2013) -
Late-Life Depression Trajectories in Relation to Health and Aging
(2018-04-24)Depression is common in older adults and has been associated with a myriad of adverse health and quality of life outcomes. However, most studies rely on a classification of depression symptoms at a single time point rather ... -
A "late-medieval" miniature in the Houghton Library
(Harvard Library, 1981) -
Late-Stage Deoxyfluorination of Alcohols with PhenoFluor
(American Chemical Society (ACS), 2013)An operationally simple protocol for the selective deoxyfluorination of structurally complex alcohols is presented. Several fluorinated derivatives of natural products and pharmaceuticals have been prepared to showcase the ... -
Late-Stage Fluorination With 19F− and 18F− via Concerted Nucleophilic Aromatic Substitution
(2016-09-09)The formation of C–F bonds has long been considered a challenging transformation and C–F bonds commonly had to be formed early on in a synthetic sequence towards complex organofluorides. Late-stage fluorination reactions ... -
Late-Stage Fluorination with \(^{18}F\)
(2013-03-19)Positron emission tomography (PET) is a powerful, non-invasive in vivo imaging technique used for diagnostics and drug development. The synthesis of \(^{18}F\)-PET tracers is challenging due to the short half-life of the ... -
Late-Stage Fluorination: From Fundamentals to Application
(American Chemical Society, 2014)In this brief account, we review work from our lab with a focus on late-stage introduction of fluorine and fluorinated functional groups into small molecules. We attempt to highlight practical developments, which we believe ... -
Late-Time Optical and Ultraviolet Spectra of SN 1979C and SN 1980K
(American Astronomical Society, 1999)A low-dispersion Keck I spectrum of SN 1980K taken in 1995 August (t = 14.8 yr after explosion) and a spectrum taken in 1997 November (t = 17.0 yr) at the MDM Observatory show broad 5500 km s(-1) emission lines of H alpha, ... -
Late-time Optical Emission From Core-collapse Supernovae
(American Astronomical Society, 2012)Ground-based optical spectra and Hubble Space Telescope images of 10 core-collapse supernovae (CCSNe) obtained several years to decades after outburst are analyzed with the aim of understanding the general properties of ...
