Life-Cycle Labor-Force Participation of Married Women: Historical Evidence and Implications
(University of Chicago Press, 1989)The seven-fold increase, since 1920, in the labor force participation rate of married women was <i>not</i> accompanied by a substantial increase in average work experience among employed married women. Two data sets giving ... -
Life: the first two billion years
(The Royal Society, 2016)Microfossils, stromatolites, preserved lipids and biologically informative isotopic ratios provide a substantial record of bacterial diversity and biogeochemical cycles in Proterozoic (2500–541 Ma) oceans that can be ... -
Lifespan-on-a-Chip: Microfluidic Chambers for Performing Lifelong Observation of C. elegans
(Royal Society of Chemistry, 2010)This article describes the fabrication of a microfluidic device for the liquid culture of many individual nematode worms (Caenorhabditis elegans) in separate chambers. Each chamber houses a single worm from the fourth ... -
Lifestyle, Weight Gain, and Pregnancy Complications from a Life-Course Perspective
(2021-07-12)Across a woman’s life, critical events occurred during each life-stage, where underlying physiological transitions take place between different stages, accompanied with weight fluctuations. Weight status is a key marker ... -
Lifetime Assessment for Thermal Barrier Coatings: Tests for Measuring Mixed Mode Delamination Toughness
(John Wiley & Sons, 2011)Mechanisms leading to degradation of the adherence of thermal barrier coatings (TBC) used in aircraft and power generating turbines are numerous and complex. To date, robust methods for the lifetime assessment of coatings ... -
The Lifetime Costs and Benefits of Medical Technology
(Elsevier, 2007)Measuring the lifetime costs and benefits of medical technologies is essential in evaluating technological change and determining the productivity of medical care. Using data on Medicare beneficiaries with a heart attack ... -
Lifetime of Double Occupancies in the Fermi-Hubbard Model
(American Physical Society, 2010)We investigate the decay of artificially created double occupancies in a repulsive Fermi-Hubbard system in the strongly interacting limit using diagrammatic many-body theory and experiments with ultracold fermions on optical ... -
Lifetime Prevalence of Dsm-Iv Mental Disorders Among New Soldiers in the U.S. Army: Results From the Army Study to Assess Risk and Resilience in Servicemembers (Army STARRS)
(Wiley-Blackwell, 2014)Background The prevalence of 30-day mental disorders with retrospectively-reported early onsets is significantly higher in the U.S. Army than among socio-demographically matched civilians. This difference could reflect ... -
Lift-Off Instability During the Impact of a Drop on a Solid Surface
(American Physical Society, 2014)We directly measure the rapid spreading dynamics succeeding the impact of a droplet of fluid on a solid, dry surface. Upon impact, the air separating the liquid from the solid surface fails to drain and wetting is delayed ... -
Ligand Field Inversion in Sterically Confined Copper Architectures
(2021-07-12)Ligand field inversion is general for high-valent cupryl (CuIII) complexes in which a physical 3d8 electronic configuration is inaccessible and metal-ligand multiple bonds (MLMBs) are unfeasible. These findings afford ... -
Ligand-Centered Redox Activity: Redox Properties of 3d Transition Metal Ions Ligated by the Weak-Field Tris(pyrrolyl)ethane Trianion
(American Chemical Society, 2010)First-row transition metal complexes of the tris(pyrrolyl)ethane (tpe) trianion have been prepared. The tpe ligand was found to coordinate in a uniform η1,η1,η1-coordination mode to the divalent metal series as revealed ... -
Light Curves of Type Ia Supernovae and Preliminary Cosmological Constraints from the ESSENCE Survey
(2013-09-30)The ESSENCE survey discovered 213 type Ia supernovae at redshifts 0.10 < z < 0.81 between 2002 and 2008. We present their R and I band light curve measurements, obtained using the MOSAIC II imager at the CTIO 4 m, along ... -
Light emission from Er at the As-terminated Si(111) surface
(AIP Publishing, 2000)Erbium atoms at an arsenic-terminated Si(111) surface can be made to emit light at the 1.55 mu m wavelength associated with an internal transition in the Er3+ ion. The As-terminated surface prepared under ultrahigh vacuum ... -
Light Scattering by Deformation of the Plane Texture of Smectic and Cholesteric Liquid Crystals
(American Physical Society, 1973)Distortions of the plane texture of smectic-A and cholesteric liquid crystals are shown to combine with the uniaxial birefringence of the plane texture to produce a strong characteristic light-scattering effect. We have ... -
Light Speed Reduction to 17 Metres per Second in an Ultracold Atomic Gas
(Nature Publishing Group, 1999)Techniques that use quantum interference effects are being actively investigated to manipulate the optical properties of quantum systems. One such example is electromagnetically induced transparency, a quantum effect that ... -
Light stops from Seiberg duality
(American Physical Society, 2012)If low-energy supersymmetry is realized in nature, a seemingly contrived hierarchy in the squark mass spectrum appears to be required. We show that composite supersymmetric theories at the bottom of the conformal window ... -
(Light) Stop Signs
(Springer Verlag, 2012)Stop squarks with a mass just above the top’s and which decay to a nearly massless LSP are difficult to probe because of the large SM di-top background. Here we discuss search strategies which could be used to set more ... -
Light-cone distortion of the clustering and abundance of massive galaxies at high redshifts
(Oxford University Press, 2008)Observational surveys of galaxies are not trivially related to single-epoch snapshots from computer simulations. Observationally, an increase in the distance along the line of sight corresponds to an earlier cosmic time ... -
Light-Quark and Gluon Jet Discrimination in pp Collisions at √S = 7 TeV With the ATLAS Detector
(Springer Nature, 2014)A likelihood-based discriminant for the identification of quark- and gluon-initiated jets is built and validated using 4.7 fb−1 of proton-proton collision data at √s = 7 TeV collected with the ATLAS detector at the LHC. ... -
Light-Scattering and Ellipsometry Studies of the Two-Dimensional Smectic-C to Smectic-A Transition in Thin Liquid-Crystal Films
(American Physical Society, 1990)Ellipsometry and light-scattering measurements are presented for the critical region near the two-dimensional XY-like smectic-C to smectic-A phase transition in thin, freely suspended films of the liquid crystal ...
