Higher Education and Authoritarian Resilience: The Case of China, Past and Present
(Harvard-Yenching Institute, 2017-03-20)Why are some autocracies more durable than others? In analyzing the institutional mechanisms that sustain authoritarian regimes, and help to explain their historical longevity as well as their persistence in the 21st ... -
Higher Education Reform in China and India: The Role of the State
(Havard-Yenching Institute, 2015) -
Higher nimbers in pawn endgames on large chessboards
(Cambridge University Press, 2002)We answer a question posed in [Elkies 1996] by constructing a class of pawn endgames on mXn boards that show the Nimbers <i>*k</i> for many large <k>k</k>. We do this by modifying and generalizing T.R. Dawson’s “pawns game” ... -
Higher Order Contributions to the 21 cm Power Spectrum

Higher Spins in AdS and Twistorial Holography
(Springer Verlag, 2011)In this paper we simplify and extend previous work on three-point functions in Vasiliev's higher spin gauge theory in \(AdS_4\). We work in a gauge in which the space-time dependence of Vasiliev's master fields is gauged ... -
Higher-Level Metazoan Relationships: Recent Progress and Remaining Questions
(Springer Science + Business Media, 2011)Metazoa comprises 35–40 phyla that include some 1.3 million described species. Phylogenetic analyses of metazoan interrelationships have progressed in the past two decades from those based on morphology and/or targeted-gene ... -
Higher-order Behavioral Contracts for Distributed Components
(2015)Inspired by the Design by Contract paradigm, we introduce CONSUL, a contract system for distributed components. CONSUL monitors distributed components at run time with higher-order behavioral contracts. Contract monitoring ... -
Highlights and discoveries from the Chandra X-ray Observatory
(IOP Publishing, 2014)Within 40 years of the detection of the first extrasolar X-ray source in 1962,NASA's Chandra X-ray Observatory has achieved an increase in sensitivity of 10 orders of magnitude, comparable to the gain in going from naked-eye ... -
Highly compliant transparent electrodes
(AIP Publishing, 2012)Adaptive optical devices based on electric field induced deformation of dielectricelastomers require transparent and highly compliant electrodes to conform to large shape changes. Electrical, optical, and actuation properties ... -
Highly conserved gene order and numerous novel repetitive elements in genomic regions linked to wing pattern variation in Heliconius butterflies
(BioMed Central, 2008)Background: With over 20 parapatric races differing in their warningly colored wing patterns, the butterfly Heliconius erato provides a fascinating example of an adaptive radiation. Together with matching races of its ... -
A highly conspicuous mineralized composite photonic architecture in the translucent shell of the blue-rayed limpet
(Nature Pub. Group, 2015)Many species rely on diverse selections of entirely organic photonic structures for the manipulation of light and the display of striking colours. Here we report the discovery of a mineralized hierarchical photonic ... -
Highly deformable actuators made of dielectric elastomers clamped by rigid rings
(AIP Publishing, 2014)In the nascent field of soft machines, soft materials are used to create devices that actuate robots, sense environment, monitor health, and harvest energy. The soft materials undergo large deformation in response to ... -
The Highly Deuterated Chemistry of the Early Universe
(IOP Publishing, 2011)A comprehensive chemistry of the highly deuterated species D2, D+ 2, D2H+, and D+ 3 in the early universe is presented. Fractional abundances for each are calculated as a function of redshift z in the recombination era. ... -
Highly directive current distributions: General theory
(American Physical Society, 1998)A theoretical scheme for studying the properties of localized, monochromatic, and highly directive classical current distributions in two and three dimensions is formulated and analyzed. For continuous current distributions, ... -
Highly Efficient Reprogramming to Pluripotency and Directed Differentiation of Human Cells with Synthetic Modified mRNA
(Elsevier BV, 2010)Clinical application of induced pluripotent stem cells (iPSCs) is limited by the low efficiency of iPSC derivation and the fact that most protocols modify the genome to effect cellular reprogramming. Moreover, safe and ... -
Highly Enantioselective, Intermolecular Hydroamination of Allenyl Esters Catalyzed by Bifunctional Phosphinothioureas
(American Chemical Society, 2014)Bifunctional phosphinothiourea catalysts have been developed successfully for the highly regio- and enantioselective γ-hydroamination of allenyl and propargyl esters with N-methoxy carbamate nucleophiles to yield α,β-unsaturated ... -
Highly parallel assays of tissue-specific enhancers in whole Drosophila embryos
(2013)Transcriptional enhancers are a primary mechanism by which tissue-specific gene expression is achieved. Despite the importance of these regulatory elements in development, responses to environmental stresses, and disease, ... -
A Highly Soluble Iron‐Based Posolyte Species with High Redox Potential for Aqueous Redox Flow Batteries
(Wiley, 2023-12-06)A novel iron‐based posolyte redox species are presented for an aqueous redox flow battery, (Tetrakis(2‐pyridylmethyl)ethylenediamine)iron(II) dichloride, which is obtained by a simple synthetic route, shows a high redox ... -
A Highly Specific Probe for Sensing Hydrogen Sulfide in Live Cells Based on Copper-Initiated Fluorogen with Aggregation-Induced Emission Characteristics
(Ivyspring International Publisher, 2014)Here we reported the first fluorescent probe with aggregation-induced emission characteristics, namely AIE-S, for the detection of hydrogen sulfide (H2S) in live cells. The detection system is selective for complicated ... -
Highly Specific, Bi-substrate-Competitive Src Inhibitors from DNA-Templated Macrocycles
(Nature Publishing Group, 2011)Protein kinases are attractive therapeutic targets, but their high sequence and structural conservation complicates the development of specific inhibitors. We recently discovered from a DNA-templated macrocycle library ...
