¹⁷O MAS NMR Correlation Spectroscopy at High Magnetic Fields
(American Chemical Society (ACS), 201711)The structure of two protected amino acids, FMOClleucine and FMOClvaline, and a dipeptide, Nacetyllvalyllleucine (NAcVL), were studied via one and twodimensional solidstate nuclear magnetic resonance (NMR) ... 
¹⁷O NMR Investigation of Water Structure and Dynamics
(American Chemical Society (ACS), 201608)The structure and dynamics of the bound water in barium chlorate monohydrate were studied with ¹⁷O nuclear magnetic resonance (NMR) spectroscopy in samples that are stationary and spinning at the magicangle in magnetic ... 
O! Canada? : a pavilion for the 2010 World Exposition in Shanghai
(Massachusetts Institute of Technology, 2008)While ninety percent of new buildings in Canada are built with light wood framing, the conventions of this construction method are seldom challenged, the economic systems behind their materials scarcely exposed, and the ... 
O(1)approximations for maximum movement problems
(Springer Berlin / Heidelberg, 201108)We develop constantfactor approximation algorithms for minimizing the maximum movement made by pebbles on a graph to reach a configuration in which the pebbles form a connected subgraph (connectivity), or interconnect a ... 
An O(log n/log log n)approximation algorithm for the asymmetric traveling salesman problem
(Society for Industrial and Applied Mathematics, 201001)We consider the Asymmetric Traveling Salesman problem for costs satisfying the triangle inequality. We derive a randomized algorithm which delivers a solution within a factor O(log n/ log log n) of the optimum with high ... 
An O(N) Algorithm for ThreeDimensional NBody Simulations
(19871001)We develop an algorithm that computes the gravitational potentials and forces on N pointmasses interacting in threedimensional space. The algorithm, based on analytical techniques developed by Rokhlin and Greengard, ... 
An O(Nm) Time Algorithm for Finding the Min Length Directed Cycle in a Graph
(Society for Industrial and Applied Mathematics, 201610)In this paper, we introduce an O(nm) time algorithm to determine the minimum length directed cycle (also called the "minimum weight directed cycle") in a directed network with n nodes and m arcs and with no negative length ... 
Oantigen diversity and lateral transfer of the wbe region among Vibrio splendidus isolates
(Blackwell Publishing, 201011)The Oantigen is a highly diverse structure expressed on the outer surface of Gramnegative bacteria. The products responsible for Oantigen synthesis are encoded in the wbe region, which exhibits extensive genetic diversity. ... 
The OD shortest path problem and connectivity problems on periodic graphs
(Massachusetts Institute of Technology, 1992) 
OO bond formation and the transition metal chemistry of [beta]diketiminate, siloxide, and triamide ligands
(Massachusetts Institute of Technology, 2012)The electrochemical splitting of water into hydrogen and oxygen has been proposed as an alternative means to store electrical energy. The limiting aspect of this reaction is the oxygen forming reaction, which can be catalyzed ... 
Osite and Tsite Occupation of αphase PdH[subscript x] and PdD[subscript x]
(International Society of Condensed Matter Nuclear Scientists (ISCMNS), 2015)An important study of the solubility of hydrogen in αphase PdH[subscript x] and deuterium in αphase PdH[subscript x] over a wide temperature range was published by Clewley et al. (J. Chem. Soc., Faraday Trans. 1: Phy. ... 
O3type Na(Mn[subscript 0.25]Fe[subscript 0.25]Co[subscript 0.25]Ni[subscript 0.25])O[subscript 2]: A quaternary layered cathode compound for rechargeable Na ion batteries
(Elsevier, 201410)We report a new layered Na(Mn[subscript 0.25]Fe[subscript 0.25]Co[subscript 0.25]Ni[subscript 0.25])O[subscript 2] compound with O3 oxygen stacking. It delivers 180 mAh/g initial discharge capacity and 578 Wh/kg specific ... 
O[superscript 6]Methylguanine DNA lesions induce an intraSphase arrest from which cells exit into apoptosis governed by early and late multipathway signaling network activation
(Royal Society of Chemistry, The, 201208)The O[superscript 6]methylguanine (O[superscript 6]MeG) DNA lesion is well known for its mutagenic, carcinogenic, and cytotoxic properties, and understanding how a cell processes such damage is of critical importance for ...
