Mechanism and Transition-State Structures for Nickel-Catalyzed Reductive Alkyne−Aldehyde Coupling Reactions
(American Chemical Society (ACS), 2009-04)The mechanism of nickel-catalyzed reductive alkyne−aldehyde coupling reactions has been investigated using density functional theory. The preferred mechanism involves oxidative cyclization to form the nickeladihydrofuran ... -
Mechanism by which surfactants modify adipic acid crystal growth rate and habit
(Massachusetts Institute of Technology, 1961) -
Mechanism design : a new algorithmic framework
(Massachusetts Institute of Technology, 2013)A modern engineering system, e.g. the Internet, faces challenges from both the strategic behavior of its self-interested participants and the inherent computational intractability of large systems. Responding to this ... -
Mechanism design : from optimal transport theory to revenue maximization
(Massachusetts Institute of Technology, 2017)A central problem in Economics and Algorithmic Game Theory is the design of auctions that maximize the auctioneer's expected revenue. While optimal selling of a single item has been well-understood since the pioneering ... -
The Mechanism Design Approach to Student Assignment
(Annual Reviews, 2011-05)The mechanism design approach to student assignment involves the theoretical, empirical, and experimental study of systems used to allocate students into schools around the world. Recent practical experience designing ... -
Mechanism design of a multi-motion automobile door
(Massachusetts Institute of Technology, 2008)This thesis describes the design and prototype construction of a multi-motion automobile door. This design is intended to provide a unique option for the opening of an automobile by enabling the door to open in two separate ... -
Mechanism Design via Optimal Transport
(Association for Computing Machinery (ACM), 2013-06)Optimal mechanisms have been provided in quite general multi-item settings [Cai et al. 2012b, as long as each bidder's type distribution is given explicitly by listing every type in the support along with its associated ... -
Mechanism Design With Approximate Player Types
(2011-02-16)We investigate mechanism design when the players do not exactly know their types, but have instead only partial information about them. -
Mechanism design with approximate types
(Massachusetts Institute of Technology, 2012)In mechanism design, we replace the strong assumption that each player knows his own payoff type exactly with the more realistic assumption that he knows it only approximately: each player i only knows that his true type ... -
Mechanism Design with Approximate Valuations
(2011-02-16)In mechanism design, we replace the strong assumption that each player knows his own payoff type EXACTLY with the more realistic assumption that he knows it only APPROXIMATELY. Specifically, we study the classical problem ... -
Mechanism design with maxmin agents: Theory and an application to bilateral trade
(The Econometric Society, 2016-09)This paper studies mechanism design when agents are maxmin expected utility maximizers. A first result gives a general necessary condition for a social choice rule to be implementable. The condition combines an inequality ... -
Mechanism Design with Set-Theoretic Beliefs
(Institute of Electrical and Electronics Engineers (IEEE), 2011-12)In settings of incomplete information, we put forward (1) a very conservative -- indeed, purely set-theoretic -- model of the beliefs (including totally wrong ones) that each player may have about the payoff types of his ... -
Mechanism design with set-theoretic beliefs
(Massachusetts Institute of Technology, 2012)In settings of incomplete information, we put forward: (1) a very conservative - indeed, purely set-theoretic- model of the beliefs (including totally wrong ones) that each player may have about the payoff types of his ... -
Mechanism design with set-theoretic beliefs
(© IEEE, 2011-10-22)In settings of incomplete information, we put forward (1) a very conservative -- indeed, purely set-theoretic -- model of the beliefs (including totally wrong ones) that each player may have about the payoff types of his ... -
Mechanism Dictates Mechanics: A Molecular Substituent Effect in the Macroscopic Fracture of a Covalent Polymer Network
(American Chemical Society (ACS), 2021)The fracture of rubbery polymer networks involves a series of molecular events, beginning with conformational changes along the polymer backbone and culminating with a chain scission reaction. Here, we report covalent ... -
Mechanism for actuating seaweed harvesting device
(Massachusetts Institute of Technology, 2019)Mechanical systems to automate a critical aspect of the seaweed farming process were designed and iterated to determine their feasibility as a substitute for human labor on a commercial large-scale seaweed farm. This paper ... -
Mechanism for enhanced oxygen reduction kinetics at the (La,Sr)CoO3−δ/(La,Sr)2CoO4+δ hetero-interface
(Royal Society of Chemistry, 2012-05)The recently reported fast oxygen reduction kinetics at the interface of (La,Sr)CoO3−δ (LSC113) and (La,Sr)2CoO4+δ (LSC214) phases opened up new questions for the potential role of dissimilar interfaces in advanced cathodes ... -
Mechanism for recombination of radiation-induced point defects at interphase boundaries
(American Physical Society, 2012-01)Interfaces play a critical role in the extraordinary resistance to irradiation damage in nanostructured materials. Atomistic simulations are performed to examine defect production and recovery at incoherent interphase ... -
Mechanism for spontaneous oxygen and hydrogen evolution reactions on CoO nanoparticles
(Royal Society of Chemistry, 2019-02)Overall photocatalytic water splitting with a high efficiency of ~5% has recently been observed for CoO nanoparticle suspensions in the absence of an applied bias or co-catalyst. Although experimental measurements indicate ... -
A mechanism for testing the torsional mechanics of origami-inspired hinges
(Massachusetts Institute of Technology, 2015)Folding 2-dimensional sheets into static and dynamic 3-dimensional structures has the potential to improve rate, cost, and flexibility in manufacturing. In order to explore origami-inspired design, a better understanding ...
