Z Boson Production in p + Pb Collisions at √s[subscript NN] = 5.02 TeV Measured with the ATLAS Detector
(2015-10)The ATLAS Collaboration measures the inclusive production of Z bosons via their decays into electron and muon pairs in p + Pb collisions at √s[subscript NN] = 5.02 TeV at the Large Hadron Collider. The measurements are ... -
Z-Drawing: A Flying Agent System for Computer-assisted Drawing
(Association for Computing Machinery (ACM), 2015-08)We present a drone-based drawing system where a user's sketch on a desk is transformed across scale and time, and transferred onto a larger canvas at a distance in real-time. Various spatio-temporal transformations like ... -
Z-Gate Operation on a Superconducting Flux Qubit via Its Readout SQUID
(American Physical Society, 2015-03)Detuning a superconducting qubit from its rotating frame is one means to implement a Z-gate operation. In this work, we implement a Z gate by pulsing a current through the qubit’s readout dc SQUID. While the dc SQUID acts ... -
Z-Selective and Syndioselective Ring-Opening Metathesis Polymerization (ROMP) Initiated by MonoAryloxidePyrrolide (MAP) Catalysts
(American Chemical Society, 2010-08)We report the Z-selective and syndioselective polymerization of 2,3-bis(trifluoromethyl)bicyclo[2.2.1]hepta-2,5-diene (NBDF6) and 3-methyl-3-phenylcyclopropene (MPCP) by monoaryloxide monopyrrolide imido alkylidene (MAP) ... -
Z-Selective Metathesis Homocoupling of 1,3-Dienes by Molybdenum and Tungsten Monoaryloxide Pyrrolide (MAP) Complexes
(American Chemical Society (ACS), 2012-06)Molybdenum or tungsten monoaryloxide pyrrolide (MAP) complexes that contain OHIPT as the aryloxide (hexaisopropylterphenoxide) are effective catalysts for homocoupling of simple (E)-1,3-dienes to give (E,Z,E)-trienes in ... -
Z-Selective Olefin Metathesis Processes Catalyzed by a Molybdenum Hexaisopropylterphenoxide Monopyrrolide Complex
(American Chemical Society (ACS), 2009-05)The molybdenum-based monoaryloxide monopyrrolide (MAP) species, Mo(NAd)(CHCMe[subscript 2]Ph)(C[subscript 4]H[subscript 4]N)(HIPTO) (2a), which contains “small” imido (Ad = 1-adamantyl) and “large” aryloxide (HIPTO = ... -
Z-Selective Olefin Metathesis Reactions Promoted by Tungsten Oxo Alkylidene Complexes
(American Chemical Society (ACS), 2011-11)Addition of LiOHMT (OHMT = O-2,6-dimesitylphenoxide) to W(O)(CH-t-Bu)(PMe[subscript 2]Ph)[subscript 2]Cl[subscript 2] led to WO(CH-t-Bu)Cl(OHMT)(PMe[subscript 2]Ph) (4). Subsequent addition of Li(2,5-Me[subscript 2]C[subscript ... -
Z-Selective Ring-Opening Metathesis Polymerization of 3-Substituted Cyclooctenes by Monoaryloxide Pyrrolide Imido Alkylidene (MAP) Catalysts of Molybdenum and Tungsten
(American Chemical Society (ACS), 2013-08)Ring-opening metathesis polymerization of a series of 3-substituted cyclooctenes (3-MeCOE, 3-HexCOE, and 3-PhCOE) initiated by various Mo and W MAP complexes leads to cis,HT-poly(3-RCOE) polymers. The apparent rate of ... -
Z/m-graded Lie algebras and perverse sheaves, I
(American Mathematical Society (AMS), 2017-09)We give a block decomposition of the equivariant derived category arising from a cyclically graded Lie algebra. This generalizes certain aspects of the generalized Springer correspondence to the graded setting. -
Z/m-graded Lie algebras and perverse sheaves, II
(American Mathematical Society (AMS), 2017-09)We consider a fixed block for the equivariant perverse sheaves with nilpotent support on the 1-graded component of a semisimple cyclically graded Lie algebra. We give a combinatorial parametrization of the simple objects ... -
Z/m-graded Lie algebras and perverse sheaves, IV
(American Mathematical Society (AMS), 2020)© 2020 American Mathematical Society. Let G be a reductive group over C. Assume that the Lie algebra g of G has a given grading (gj ) indexed by a cyclic group Z/m such that g0 contains a Cartan subalgebra of g. The subgroup ... -
Z2 [Z subscript 2] spin liquids in the S=1/2 Heisenberg model on the kagome lattice: A projective symmetry-group study of Schwinger fermion mean-field states
(American Physical Society, 2011-06)Due to strong geometric frustration and quantum fluctuation, the S = 1/2 quantum Heisenberg antiferromagnet on the kagome lattice has long been considered as an ideal platform to realize a spin liquid (SL), a phase exhibiting ... -
ZAC: A zone path construction approach for effective real-time ridesharing
(AAAI Press, 2019-07)Real-time ridesharing systems such as UberPool, Lyft Line, GrabShare have become hugely popular as they reduce the costs for customers, improve per trip revenue for drivers and reduce traffic on the roads by grouping ... -
Zanamivir Conjugated to Poly-L-Glutamine is Much More Active Against Influenza Viruses in Mice and Ferrets Than the Drug Itself
(Springer-Verlag, 2013-09)Purpose: Previously, polymer-attached zanamivir had been found to inhibit influenza A viruses in vitro far better than did small-molecule zanamivir (1) itself. The aim of this study was to identify in vitro—using the ... -
ZBED6, a Novel Transcription Factor Derived from a Domesticated DNA Transposon Regulates IGF2 Expression and Muscle Growth
(Public Library of Science, 2009-12)A single nucleotide substitution in intron 3 of IGF2 in pigs abrogates a binding site for a repressor and leads to a 3-fold upregulation of IGF2 in skeletal muscle. The mutation has major effects on muscle growth, size ... -
Zebrafish as a model to study live mucus physiology
(Nature Publishing Group, 2014-10)Dysfunctional mucus barriers can result in important pulmonary and gastrointestinal conditions, but model systems to study the underlying causes are largely missing. We identified and characterized five mucin homologues ... -
Zebrafish cerebrospinal fluid mediates cell survival through a retinoid signaling pathway
