Heating, weakening and shear localization in earthquake rupture
(The Royal Society, 2017-08-21)Field and borehole observations of active earthquake fault zones show that shear is often localized to principal deforming zones of order 0.1-10 mm width. This paper addresses how frictional heating in rapid slip weakens ... -
Heavy Hitters via Cluster-Preserving Clustering
(IEEE, 2016-10)In the turnstile ℓp heavy hitters problem with parameter ε, one must maintain a high-dimensional vector x ∈ ℝn subject to updates of the form update (i,Δ) causing the change xi ← xi + Δ, where i ε[n], Δ ∈ ℝ. Upon receiving ... -
Heavy-tailedness and Threshold Sex Determination.
(Elsevier, 2008)This paper studies the properties of the sex ratio in two-period models of threshold (e.g., polygenic or temperature-dependent) sex determination under heavy-tailedness in the framework of possibly skewed stable distributions ... -
Hecke Operators on Quasimaps into Horospherical Varieties
(University Bielefeld, Fakultat Mathematik, 2009)Let G be a connected reductive complex algebraic group. This paper and its companion [GN06] are devoted to the space Z of meromorphic quasimaps from a curve into an affine spherical G-variety X. The space Z may be thought ... -
Hedgehogs (Erinaceidae, Lipotyphla) from the Miocene of Pakistan, with description of a new species of Galerix
(Springer Science + Business Media, 2015)Hedgehogs (erinaceid insectivores) are a common element in Miocene small mammal faunas of Pakistan, but little material has been formally described. Here, we report on extensive collections from numerous localities across ... -
Hegel's Metaphysics of Rational Life: Overcoming the Pippin-Houlgate Dispute
(Cambridge University Press (CUP), 2023-10-25)In the past decade, the meaning of Hegel's idea of a ‘science of logic’ has become a matter of intense philosophical debate. This article examines the two most influential yet opposed contemporary readings of the Science ... -
Height, Socioeconomic and Subjective Well-Being Factors among U.S. Women, Ages 49–79
(Public Library of Science (PLoS), 2014)Background: A vast literature has associated height with numerous factors, including biological, psychological, socioeconomic, anthropologic, genetic, environmental, and ecologic, among others. The aim of this study is to ... -

Heisenberg-Limited Atom Clocks Based on Entangled Qubits
(American Physical Society (APS), 2014)We present a quantum-enhanced atomic clock protocol based on groups of sequentially larger Greenberger-Horne-Zeilinger (GHZ) states that achieves the best clock stability allowed by quantum theory up to a logarithmic ... -
Helen Epigrammatopoios
(University of California Press, 2005)Ancient commentators identify several passages in the Iliad as “epigrams.” This paper explores the consequences of taking the scholia literally and understanding these passages in terms of inscription. Two tristichs spoken ... -
Heliodoros' "Sources": Intertextuality, Paternity, and the Nile River in the Aithiopika
(Johns Hopkins University Press, 2008)Kharikleia, the heroine of Heliodoros’s Aithiopika, shares with the novel a tripartite identity; she is a metaphor for the incorporation of multiple literary models into a single text. Heliodoros sets up the Nile river as ... -

The HELIX project
(IEEE, 2012)Parallelism has become the primary way to maximize processor performance and power efficiency. But because creating parallel programs by hand is difficult and prone to error, there is an urgent need for automatic ways of ... -
HELIX: Automatic Parallelization of Irregular Programs for Chip Multiprocessing.
(Association for Computing Machinery, 2012)We describe and evaluate HELIX, a new technique for automatic loop parallelization that assigns successive iterations of a loop to separate threads. We show that the inter-thread communication costs forced by loop-carried ... -
Helix: Making the Extraction of Thread-Level Parallelism Mainstream
(Institute of Electrical & Electronics Engineers (IEEE), 2012)Improving system performance increasingly depends on exploiting microprocessor parallelism, yet mainstream compilers still don't parallelize code automatically. Helix automatically parallelizes general-purpose programs ... -
Hellenistic Landscapes and Seleucid Control in Mesopotamia: The View from the Erbil Plain in Northern Iraq
(University of Chicago Press, 2022-07-01)In this article we discuss the archaeological landscapes of the Erbil plain during the Hellenistic period (late fourth century BCE–mid second century BCE) based on the data collected during the Erbil Plain Archaeological ... -
Hematite Spherules at Meridiani: Results from MI, Mini-TES, and Pancam
(American Geophysical Union, 2008)We report on observations of hematite-bearing spherules at Meridiani Planum made using the Microscopic Imager (MI), Mini-Thermal Emission Spectrometer (Mini-TES), and Panoramic Camera (Pancam) instruments on the Mars ... -
Hematopoietic Defects in rps29 Mutant Zebrafish Depend Upon p53 Activation
(Elsevier BV, 2012)Disruption of ribosomal proteins is associated with hematopoietic phenotypes in cell culture and animal models. Mutations in ribosomal proteins are seen in patients with Diamond Black- fan anemia, a rare congenital disease ... -
HEMCO v1.0: a versatile, ESMF-compliant component for calculating emissions in atmospheric models
(Copernicus GmbH, 2014)We describe the Harvard–NASA Emission Component version 1.0 (HEMCO), a stand-alone software component for computing emissions in global atmospheric models. HEMCO determines emissions from different sources, regions, and ...
