The Z axis and its composite matrix of perception
(Massachusetts Institute of Technology, 2016)Beliefs and ideas mingle with our perceptions of physical objects and spaces as the same cognitive material. Within a conceptual mental space, these perceptions constitute a composite matrix of perception. When we navigate ... -
Z boson cross section measurements and neutral Higgs boson search in the di-muon channel with the CMS detector
(Massachusetts Institute of Technology, 2019)In this thesis, measurements of inclusive and differential Z boson production cross sections in proton-proton collisions at [square root of] s =13 TeV with the CMS detector at Large Hadron Collider are performed with the ... -
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 and Cis/syndioselective ROMP with high oxidation state molybdenum alkylidenes
(Massachusetts Institute of Technology, 2012)Chapter 1: Reaction of W(CCMe3)Cl 3(dme) with one equivalent of (3,5-Me 2C6H3NCH2CH 2)3N)Li3 affords yellow, crystalline W(CCMe3)(N3N) in good yield. The reactivity of this new alkylidyne complex towards terminal alkynes ... -
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-source circuit breakers in naval power systems
(Massachusetts Institute of Technology, 2019)New power system components and control systems are required to facilitate the U.S. Navy's move to medium voltage direct current power (MVDC) systems on future vessels. Integrating the z-source circuit breaker into a ... -
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 ... -
