HIV-Specific CD4 T Cells and Viral Control
(2015-01-15)CD4 T cells play an important and central role in the immune system, coordinating the arms of the adaptive immune system to shape an effective response while simultaneously regulating non-essential or deleterious activities. ... -
[(HL)2Fe6(NCMe)m]n+ (m = 0, 2, 4, 6; n = −1, 0, 1, 2, 3, 4, 6): An Electron-Transfer Series Featuring Octahedral Fe6 Clusters Supported by a Hexaamide Ligand Platform
(American Chemical Society (ACS), 2011)Using a trinucleating hexaamide ligand platform, the all-ferrous hexanuclear cluster (HL)2Fe6 (1) is obtained from reaction of 3 equiv of Fe2(Mes)4 (Mes = 2,4,6-Me3C6H2) with 2 equiv of the ligand (HL)H6. Compound 1 was ... -
HNC in Protoplanetary Disks
(IOP Publishing, 2015)The distributions and abundances of small organics in protoplanetary disks are potentially powerful probes of disk physics and chemistry. HNC is a common probe of dense interstellar regions and the target of this study. ... -
The HNC/HCN Ratio in Star-Forming Regions
(IOP Publishing, 2014)HNC and HCN, typically used as dense gas tracers in molecular clouds, are a pair of isomers that have great potential as a temperature probe because of temperature dependent, isomer-specific formation and destruction ... -
Hobbes and the Foundations of Modern International Thought
(Cambridge University Press, 2006)Quentin Skinner concluded The Foundations of Modern Political Thought (1978) with the claim that '[b]y the beginning of the seventeenth century, the concept of the State -- its nature, its powers, its right to command ... -
Hodge Theory and Unitary Representations of Reductive Lie Groups
(International Press, 2011)We present an application of Hodge theory towards the study of irreducible unitary representations of reductive Lie groups. We describe a conjecture about such representations and discuss some progress towards its proof. -
Hog1 Controls Global Reallocation of RNA Pol II upon Osmotic Shock in Saccharomyces cerevisiae
(Genetics Society of America, 2012)When challenged with osmotic shock, Saccharomyces cerevisiae induces hundreds of genes, despite a concurrent reduction in overall transcriptional capacity. The stress-responsive MAP kinase Hog1 activates expression of ... -

Hold-Up, Asset Ownership, and Reference Points
(Oxford University Press (OUP), 2009)We study two parties who desire a smooth trading relationship under conditions of value and cost uncertainty. A contract fixing price works well in normal times because there is nothing to argue about. However, when value ... -
Holding the Empire Together: Caracas Under the Spanish Resistance During the Napoleonic Invasion of Iberia
(2014-06-06)The Napoleonic invasion of Iberia shattered the Spanish empire in 1808. The French emperor occupied Spain and forced Ferdinand VII to abdicate the throne. Once the war against the French began, most vassals also rejected ... -
Hole dynamics in an antiferromagnet across a deconfined quantum critical point
(American Physical Society, 2007)We study the effects of a small density of holes, delta, on a square-lattice antiferromagnet undergoing a continuous transition from a Neel state to a valence bond solid at a deconfined quantum critical point. We argue ... -
Hole Dynamics in the Two-Dimensional Strong-Coupling Hubbard Hamiltonian
(American Physical Society, 1988)The effective Hamiltonian, obtained from the Hubbard model in the strong-coupling limit, is diagonalized exactly for a periodic two-dimensional square lattice of ten sites. We obtain the ground state of the system for any ... -
Hole Spin Relaxation in Ge-Si Core-Shell Nanowire Qubits
(Nature Publishing Group, 2012)Controlling decoherence is the biggest challenge in efforts to develop quantum information hardware. Single electron spins in gallium arsenide are a leading candidate among implementations of solid-state quantum bits, but ... -
Holographic Derivation of Kerr-Newman Scattering Amplitudes for General Charge and Spin
(Springer, 2010)Near-superradiant scattering of charged scalars and fermions by a near-extreme Kerr-Newman black hole and photons and gravitons by a near-extreme Kerr black hole are computed as certain Fourier transforms of correlators ... -
Holographic Detection of the Orbital Angular Momentum of Light With Plasmonic Photodiodes
(Nature Publishing Group, 2012)Metallic components such as plasmonic gratings and plasmonic lenses are routinely used to convert free-space beams into propagating surface plasmon polaritons and vice versa. This generation of couplers handles relatively ... -
Holographic Domains of Anti-de Sitter Space
(Springer Verlag, 2002)An AdS4 brane embedded in AdS5 exhibits the novel feature that a four-dimensional graviton is localized near the brane, but the majority of the infinite bulk away from the brane where the warp factor diverges does not see ... -
Holographic Measurements of Anisotropic Three-Dimensional Diffusion of Colloidal Clusters
(American Physical Society, 2013)We measure all nonzero elements of the three-dimensional diffusion tensor D for clusters of colloidal spheres to a precision of 1% or better using digital holographic microscopy. We study both dimers and triangular trimers ... -
