▼ We apply computer science techniques to try to solve a selection of problems that arise in economics and electronic commerce. The problems we address and our results are summarized below. The first problem is from the field of Mechanism Design. The goal is to find a procedure for allocating identical items among agents with private values in the manner that maximizes the total utility of the agents. We approach this problem computationally: solutions are found algorithmically rather than through mathematical derivations. Our computational approach yields a nearly optimal solution greatly improving prior results. In the case with 3 agents and 2 items, we were able to find a provably optimal solution. Next, we address a game-theoretic problem of finding Nash Equilibria in auctions. We investigate when a computational procedure finds an equilibrium in first and second price auctions with discrete bids and values. The rest of the thesis is devoted to automated decision making in electronic commerce domains. Three domains are considered: sponsored search, supply chain management, and simultaneous auctions. The last two domains are studied in the context of the SCM and Travel divisions of the Trading Agent Competition (TAC). Our contributions to automated decision making are both practical and theoretical. On the practical side, the bidding strategy we designed for sponsored search auctions is currently being used by a large advertiser. Our work on TAC Travel culminated in winning the competition in 2006. In the TAC SCM competition, the agent we built was among the top 5 out of over 20 agents almost every year of the competition. For theoretical contributions, we characterized optimal strategies for bidding in simultaneous auctions when prices are known and complemented this analysis with an empirical comparison of different strategies. We identified that bidding decisions in TAC SCM can be modeled as a non-linear knapsack problem and proved the asymptotic optimality of a greedy algorithm for solving a class of non-linear knapsack problems.

▼ Using a direct ultraviolet second-derivative spectroscopy method, three peroxynitrite preparative methods were investigated for the nitrite and nitrate present either as impurities or produced during peroxynitrite decomposition: (I) ozonation of azide, reaction of hydrogen peroxide with (II) isoamyl nitrite and (III) nitrous acid. The oxidation of morpholine by peroxynitrite in the presence and absence of added carbonate gives N-nitromorpholine and N-nitrosomorpholine. Nitration and nitrosation of morpholine are catalyzed by low levels of CO₂; however, excess CO₂ dramatically reduces the yields of nitrosation but not nitration, and the combined yields of the products are about the same under conditions of high and low concentrations of CO₂. These data indicate that both nitration and nitrosation by peroxynitrite are free radical processes. The morpholine radical, formed from the reactions of carbonate and/or hydroxyl radicals with morpholine, reacts with either ^•NO or ^•NO₂ and serves as a common precursor for both products. The peroxynitrite-mediated oxidation of α-tocopherol and γ-tocopherol dispersed in 1,2-dilauroyl-<i>sn</i>-glycero-3-phosphocholine liposomes in the presence and absence of added carbonate gives α-tocopherylquinone and 5-nitro-γ-tocopherol, respectively. The formation of the products is consistent with the current understanding of the free radical nature of oxidations of peroxynitrite and its CO₂-adducts; the overall reaction involves a one-electron oxidation of α-tocopherol and γ-tocopherol by HO^• or CO₃^•-, followed by the reaction with ^•NO₂. When α-tocopherol and γ-tocopherol were present in the same liposome and exposed to peroxynitrite, there was preferential oxidation of α-tocopherol over γ-tocopherol. An explanation for the protection of γ-tocopherol by α-tocopherol could be that γ- and α-tocopheryl radicals, formed from the respective reactions of α-tocopherol and γ-tocopherol with HO^• or CO₃^•-, disproportionate to give α-tocopherylquinone and regenerated γ-tocopherol. This is consistent with the lack of protection of γ-tocopherol by α-tocopherol when α-tocopherol and γ-tocopherol dispersed in different liposomes but present in the same incubation mixer are subjected to oxidation by peroxynitrite.

▼ Voluntary contribution mechanism (VCM) public good experiments aim to analyze economic behavior of individuals in a prisoners dilemma type setting. In the most basic set-up of the game, a common observance is that the cooperation level, although starting high, tends to peter out as the game progresses and free-riding behavior increases. One explanation offered is that at least some subjects fail to understand the best strategic response at first, so that it takes some time for the contribution levels to converge to the theoretical Nash equilibrium where every subject chooses to free-ride. However, introducing variation to the game design such as sanctions and re-grouping, has been shown to weaken or even reverse this trend. The first chapter introduces a ?reciprocity model? in which the subjects are allowed to gain utility from matching their contributions to those done by other players in their group, and tests the model against a ?learning to free-ride? model in terms of simulation of actual behavior. It is shown that the reciprocity approach generates lower simulation errors in most cases, both on subject and group level. The second chapter looks at the effects of regrouping subjects according to their observed contribution and punishment behavior, in a VCM with sanctions settings. The results show that (1) behavior in the first five periods can be used as a prediction of later actions, especially if the regrouping is done relatively earlier, and (2) homogeneous grouping of high contributors increase the group earnings significantly. The last chapter tests the effects of revealing additional information about pre-sanctions potential monetary earnings and punishment behavior of others in the group. Significant differences in behavior are observed as a result; and while revealing potential earning information leads to significantly higher earning levels in groups, revealing punishment information does not. Each chapter is organized as a stand-alone working paper. Advisors/Committee Members: Putterman, Louis (director), Page, Tobias (reader), Spolaore, Enrico (reader).

▼ The biological activity of azasugars has largely been attributed to their ability to mimic the oxocarbenium ion-like transition state formed during reactions with carbohydrate-processing enzymes and, for this reason, functional and stereochemical modifications of the azasugar scaffold have led to the development of specific and potent glycosidase inhibitors. Given the potential of azasugars as glycosidase inhibitors, we were interested in developing efficient methodology for their synthesis. This thesis highlights synthetic methodology developed to produce amino-imino-hexitols as azasugar scaffolds. Key in the synthesis of the amino-imino-hexitols was the application of a stereoselective Strecker reaction, without the need for chiral Lewis acids or catalysts, and an extension of an I2-mediated carbamate annulation to cyclise functionalised and protected alkenylamines. Sixteen amino-imino-hexitols were synthesized, including ten previously undisclosed substrates with the D-galacto, D-talo, and L-altro configurations. The novel amino-imino-hexitols were then tested for their ability to act as glycosidase inhibitors and substrates of the D-talo configuration showed promising inhibitory effects. Mechanistic considerations of the I2-mediated carbamate annulation are discussed and although the exact annulation mechanism has yet to be determined, experimental studies have revealed that an aziridine is not an intermediate in the reaction. Factors influencing the diastereoselectivity of the carbamate annulation are also explored. Furthermore, an in depth analysis of the high cis-selectivity of the carbamate annulation is investigated using density functional theory to calculate the transition states of iodocyclisations en route to the formation of carbamates. Taken as a whole, the applicability of the carbamate annulation to a variety of alkenylamines and an understanding of the factors controlling the diastereoselectivity of the reaction should make this methodology a valuable addition to the synthetic chemist’s toolbox.

▼ Natural products and natural product derivatives have been the leading source of pharmaceutical compounds since the initial application of modern medicine. To fight the increasing occurrence of drug resistance and to reach the ultimate goal of personalized drugs for treating complicated symptoms, novel natural products are demanded. Lanthipeptides are ribosomal peptides with post-translationally incorporated thioether crosslinks named lanthionine. This family of natural products has garnered substantial attention during the past few decades due to their favorable biological activities and the potential for engineering. This thesis focuses on a subclass of lanthipeptides, the class II compounds, for which the synthesis of dehydroamino acids and the formation of thioether linkages are carried out by a bifunctional lanthionine synthetase. Chapter 2 presents the structural characterization of the enterococcal cytolysin, a lanthipeptide tightly linked to Enterococcus faecalis virulence. The stereoselectivity of lanthionine synthesis is discussed in chapters 3 and 4. A non-canonical configuration of lanthionines was discovered in a few lanthipeptides and the selective synthesis of the unusual stereochemistry was found to be induced by the peptide sequence rather than the lanthionine synthetase. Such a substrate-controlled stereoselectivity is rarely identified in naturally occurring enzymatic processes. Although it has been more than ten years since the first in vitro reconstitution of a class II lanthionine synthetase, no structural information was available for this class of proteins before the study presented in chapter 5 with respect to the cytolysin synthetase CylM. Unexpectedly, the CylM dehydratase domain resembles the catalytic core of lipid kinases despite the absence of notable sequence homology. Mutagenesis study of CylM provides further insights into the mechanism of the modification process. The maturation of lanthipeptides typically requires a proteolytic step that removes the leader peptide from the modified precursor peptides. Characterization of two peptidases involved in the synthesis of lichenicidin and cytolysin, described in chapters 6 and 7, provides mechanistic insights into these subtilisin-like proteins and reveals their potential as sequence-specific proteases. In addition, structural elucidation of four prochlorosins, a set of lanthipeptides synthesized by a highly substrate-tolerant synthetase ProcM in marine bacteria, is included as chapter 8. The unveiled structural information of these lanthipeptides and the biochemical studies with respect to the biosynthetic process described in this thesis may assist the genome mining and synthetic biology efforts towards novel lanthipeptides for therapeutic purposes and other applications.

▼ The discovery of induced pluripotent stem cells (iPSCs) has transformed the research of stem cells and provided infinite possibilities in regenerative medicine. In classical Yamanaka protocol, somatic cells from various sources can be reprogrammed to iPSCs with forced expression of Oct4, Sox2, Klf4, and cMyc. Numerous other combinations of factors and various delivery methods have also been developed to optimize the efficiency and accustom to different applications. These iPSCs are useful for disease modeling, toxicology studies and cell therapy. However, the molecular mechanisms of this transformation remain largely unclear. The transition from somatic cells to iPSCs involved comprehensive changes on epigenetic level of the cells induced by reprogramming factors. Reprogramming factor Klf4 can physically interact with Oct4 and Sox2. These three transcription factors co-occupy promoters of many pluripotency related genes, such as endogenous Nanog and Oct4. The physical interactions depend on the C2H2 zinc fingers in Klf4. Abrogation of these interactions will lead to failure of reprogramming due to the inability of defective complexes in activating key downstream genes. These results suggest that direct interactions between reprogramming factors are essential for initiating key downstream genes. During reprogramming, nuclear architecture of the cells also experience dramatic changes. In pluripotent stem cells (PSCs), endogenous Oct4 loci interact with distant regions in cis and in trans. Many of these long range interactions are specific to PSCs. PSC-specific interchromosomal interactions are established prior to transcriptional activation of endogenous Oct4 during reprogramming. In PSCs, Oct4-colocalized domains are enriched in active genes and pluripotency factor binding. Transcription of Oct4 is facilitated when the Oct4 locus is co-localized with its interchromosomal partners. Finally, depletion or overexpression of Klf4 causes changes in interchromosomal interactions prior to loss of Oct4 transcription and PSC differentiation, suggesting that Klf4 regulates interchromosomal interactions independent of its role as a transcription factor. Together these results reveal two novel essential factors in facilitating reprogramming: physical interactions between reprogramming factors and nuclear architecture dynamics.

▼ This thesis addresses problems in the area of mechanism design. In many settings in winch collective decisions are made, individuals' actual preferences are not publicly observable. As a result, individuals should be relied on to reveal this information. We are interested in an important application of mechanism design, which is the construction of desirable procedures for deciding upon resource allocation or task assignment. We make two main contributions. First, we propose a new mechanism for allocating a divisible commodity between a number of buyers efficiently and fairly. Buyers are assumed to behave as price-anticipators rather than as price-takers. The proposed mechanism is as parsimonious as possible, in the sense that it requires participants to report a one-dimensional message (scalar strategy) instead of an entire utility function, as required by Vickrey-Clarke-Groves (VCG) mechanisms. We show that this mechanism yields efficient allocations in Nash equilibria and moreover, that these equilibria are envy-free. Additionally, we present distinct results that this mechanism is the only simple scalar strategy mechanism that both implements efficient Nash equilibria and satisfies the no envy axiom of fairness. The mechanism's Nash equilibria are proven to satisfy the fairness properties of both Ranking and Voluntary Participation. Our second contribution is to develop optimal VCG mechanisms in order to assign identical economic "bads" (for example, costly tasks) to agents. An optimal VCG mechanism minimizes the largest ratio of budget imbalance to efficient surplus over all cost profiles. The optimal non-deficit VCG mechanism achieves asymptotic budget balance, yet the non-deficit requirement is incompatible with reasonable welfare bounds. If we omit the non-deficit requirement, individual rationality greatly changes the behavior of surplus loss and deficit loss. Allowing a slight deficit, the optimal individually rational VCG mechanism becomes asymptotically budget balanced. Such a phenomenon cannot be found in the case of assigning economic "goods."

▼ The need for the study arises from the assumption that the present liaison mechanism between architects in the private sector and the Transvaal Provincial Administration is deficient. The weaknesses are defined and presented by way of sub-problems and hypotheses arising therefrom. In order to limit the extent of the research and investigations, the study is confined to the liaison mechanism relating to primary schools only, within the Province of Transvaal. The data have been obtained from replies to questionnaires received from selected but individually unidentifiable architects in private practice as well as from answers to a standard set of questions verbally put to officials in various State departments. To further illustrate weaknesses in briefing and communication, a few case histories have been described. The assessment by related literature has largely been confined to the views of educationists, sociologists, economists and architects. In essence, these views accentuated the importance of sound communication, role expectation and role perception amongst the professionals representing the various disciplines engaged in the need for design and construction of educational buildings. Related literature leaves no doubt as to the importance of correct selection and acceptance of the architect as the leader of the professional team. A detailed investigation of the present liaison mechanism clearly reveals the areas of weakness which consequently affect efficiency as well as the steps that can be taken to improve the efficacy of the liaison mechanism. The progressive stages of a project from its inception to its completion are discussed in strict chronological order and in detail, leaving no doubt as to where the delays can and do occur. In conclusion, an effort is made to pinpoint the areas which need attention. Recommendations are also suggested in regard to eliminating any misunderstandings in role perception and expectation, and for the improvement and accuracy of the initial briefing.

▼ The removal of nitrogen oxides (NOx) from exhaust and flue gases is a demanding technical problem particularly in the presence of excess oxygen. The reduction of nitrogen oxides by hydrocarbons (HC-SCR) is a promising but also challenging method to utilize in applications, where fuels like diesel oil or natural gas might be used as a reductant. In this work new high activity HC-SCR catalysts were developed based on metal oxides (cobalt, indium, gallium) supported on sol-gel aluminum oxide or ZSM-5 zeolite. The interaction of indium and cobalt with aluminum oxide was studied by the catalysts prepared by impregnation, sol-gel, ion exchange and mechanical mixing methods. The active compounds were Co2+ on Co/Al2O3, In2O3 on In/Al2O3 and intrazeolitic InO+ on In/ZSM-5. A significant promotion in NOx conversions was reached by mechanically mixing a small amount (5%) of Mn3O4 with In/Al2O3 or Ga/Al2O3 in propene-SCR and Mn3O4 or Pt/Al2O3 with In/ZSM-5 in methane-SCR. Gaseous or mobile surface intermediates are necessary to explain the observed promotion. Pt/alumina and Mn3O4 seemed themselves to catalyze the N2 formation step in addition to promotion on HC and NO oxidation. Surface intermediates were detected by in situ FTIR in the presence of flowing reaction gas mixtures. Before the reaction initiation the catalyst surface was usually covered with the inhibiting compounds (nitrates, carbonates), which disappeared at higher reaction temperatures (300-400°C) and the amount of surface reactants remained low in HC-SCR operation window (> 300°C). The derived reaction mechanisms for SCR by light hydrocarbons (C1-C3) included six potential surface reductants (H2NCO, HNCO, NCO, NH2, NH, N) for NO. The reductants with NHi functional groups were found to be final reductants and the adsorbed NH2 (amine) was the most probable in a single surface reaction. The micro-kinetic modeling based on surface reactions was used parallel to other methods to evaluate the reaction routes and dynamics. The kinetic models for propene-SCR with Co/alumina and methane-SCR with In/ZSM-5 were based on the assumption that adsorbed H2NCO (amide) acts as the reductant for NO. The improved model for methane-SCR on In/ZSM-5 was based on a mechanism where NO is reduced by NH2. The binary catalyst combination (In/ZSM-5+Pt/Al2O3) was modeled using two different NO reduction mechanisms assuming NH2 path on indium sites and NO decomposition to nitrogen on platinum sites. The models were able to quantitatively describe the concentrations of all observed gaseous reactants and products and as well as the defined surface coverages in propene- and methane-SCR. Finally, a generic reaction mechanism for HC-SCR was proposed. The analysis of NO-H2 reactions in transient conditions on Pt, Pt-Rh and Rh three-way catalysts was used as a tool to categorize the NOx reduction mechanisms. The NOx reduction studies resulted in four mechanisms to form nitrogen: 1) N route, 2) N2O route, 3) ONNO route and 4) NHi route. In fact, nitrogen formation on three-way and HC-SCR… Advisors/Committee Members: Helsinki University of Technology, Department of Chemical Technology, Laboratory of Industrial Chemistry.

▼ Particle size, phase, and transition metals have all been implicated in natural and engineered silica-induced respiratory effects, as well as cellular interactions. However, efforts to unambiguously determine their role in the pro-inflammatory mechanism induction have been hampered due to the use of inhomogeneous samples, with incomplete characterization and the use of high cytotoxic doses. Here, engineered micro- and nano- sized silica particles, which are more homogenous in their materials properties and used in a variety of applications, were characterized and compared to natural silica at a realistic dose level. Natural (2 μm) and engineered silica particles (2 μm and 50 nm) were characterized and controlled for size, morphology, phase, iron presence, surface area, and aggregation. A novel lipid peroxidation-dependent pro-inflammatory mechanism due to the influence of iron, particle size, and phase was hypothesized for these particles under a low non-cytotoxic dose closer to a realistic exposure regime. It was observed that at a 1 μg/ml low non-cytotoxic dose of silica the presence or addition of iron, reduction of particle size, and crystalline phase of natural silica significantly increased superoxide (O2.-) and hydrogen peroxide (H2O2) production in the macrophages. This increase in O2.- and H2O2 production, further lead to phosphatidylcholine-specific phospholipase C (PC-PLC) - mediated inflammatory mediator or cytokine production in macrophages via lipid peroxidation and lipid raft disruption (large fraction sub-domains of plasma membrane involved in signal transduction). Addition of an iron chelator abrogated these responses, supporting the role of iron in the hypothesized mechanism. Activation of PC-PLC - induced inflammatory response was determined by using PC-PLC inhibitor, Tricychodecan-9-yl-xanthate, which blocked the inflammatory mediator production. Microscopy studies with cell-particle interaction revealed that particle size also influenced the uptake of silica particles in the macrophages mainly via phagocytosis, since binding and activation of membrane receptors and subsequent internalization is strongly dependent on nanoparticle size. Also, a high cytotoxic dose of 100 μg/ml showed macrophage particle overload for both particle sizes, with macrophage damage possibly leading to catastrophic release of inflammatory mediators that could obfuscate study of the normal inflammatory response, emphasizing the need for studies with realistic exposure doses. In summary, this work demonstrated the role of particle size, iron, and phase in a lipid raft dependent-inflammatory mechanism induced by particles at a realistic exposure dose via PC-PLC. It should lead to a better understanding of the mechanism and important parameters for the particle-induced inflammatory response of the lungs, and therefore, control of the respiratory effects caused by real-life exposure to natural and engineered particles.

▼ Chapter 1. A literature review of supramolecular reaction control and the efforts made towards developing supramolecular catalysts is presented. Representative examples of the fundamental ways in which supramolecular encapsulation can promote reactivity are given, with emphasis placed on catalytic reactions involving self-assembled hosts. The [Ga4L6]12- supramolecular assembly developed by the Raymond group is introduced, and previous work on its ability to enhance the reactivity of its encapsulated guests is reviewed.Chapter 2. The tetrahedral [Ga4L6]12- assembly encapsulates propargyl enammonium cations capable of undergoing the aza Cope rearrangement. For propargyl enammonium substrates that are encapsulated in the [Ga4L6]12- assembly, rate accelerations of up to 184 are observed when compared to the background reaction. After rearrangement, the product iminium ion is released into solution and hydrolyzed allowing for catalytic turnover. The activation parameters for the catalyzed and uncatalyzed reaction were determined, revealing that a lowered entropy of activation is responsible for the observed rate enhancements. The catalyzed reaction exhibits saturation kinetics; the rate data obey the Michaelis-Menten model of enzyme kinetics, and competitive inhibition using a non-reactive guest has been demonstrated. Chapter 3. The tetrahedral [Ga4L6]12- assembly catalyzes the Nazarov Cyclization of 1,3-pentadienols with extremely high levels of efficiency. The catalyzed reaction proceeds at a rate over a million times faster than that of the background reaction, an increase comparable to those observed in some enzymatic systems. This catalysis operates under aqueous conditions at mild temperature and pH ranges, and the reaction is halted by the addition of an appropriate inhibitor. The product of this reaction, pentamethylcyclopentadiene, is a competitive guest in the host assembly, and the catalysis suffers from product inhibition. This was alleviated by the addition of maleimide, which readily undergoes a Diels-Alder reaction with the product to form a more weakly-encapsulated adduct.Chapter 4. The kinetically-controlled, regioselective deprotonation of cyclopentenyl cations mediated by encapsulation within the [Ga4L6]12- assembly is presented. The regiochemistry of the deprotonation step determines which one of two possible products is formed. Although this deprotonation step occurs at both possible positions outside the host interior, encapsulation renders the process >95% regioselective. Moreover, subtle differences in the stereochemistry of the encapsulated cyclopentenyl cation switch the product selectivity of this process. This reactivity shares several features with the regioselective, enzyme-controlled deprotonation of the geranyl cation involved in the biosynthesis of myrcene and β-ocimene.Chapter 5. Mechanistic studies of the processes described in the two preceding chapters are presented. A combined experimental and computational approach is used to elucidate the reaction mechanism of…

▼ In this project, the synthesis of carbon encapsulated copper nanoparticles using sustainable bioproducts as raw material was systematically studied. The synthesis mechanism, process parameters, and functionalization of carbon encapsulated copper nanoparticles were well established. In a preliminary study, carbon encapsulated copper nanoparticles were successfully synthesized at 1000 ºC, 1h, 20 ºC/min, and 1800 sccm argon gas flow rate using BCL-DI lignin as the carbon source. Carbon encapsulated copper nanoparticles were mainly located at defect sites. Copper was found not tightly encapsulated by graphene shells. The carbon encapsulated copper nanoparticles were uniformly distributed. The conversion of copper ions into copper atoms occurred at above 300 ºC, with the company of decomposition of BCL-DI lignin into CO, CO2, and hydrocarbon gases. The growth of graphene layers was proposed to start above 300 ºC. TEM images illustrated the onset of growth of graphene at the edge of the surface at 400 ºC, and the formation of graphene bands at 500 ºC. Copper catalyst continued to facilitate the decomposition of lignin functional groups at 600 ºC. Further increasing the temperature retarded the degradation of lignin, while assisted the reconstruction of the defective sites of the graphene layers, producing higher quality products. Plastic film phase of lignin dominated on the synthesis of carbon encapsulated copper nanoparticles, while gaseous phase had little impact. The orthogonal experiment revealed that temperature played the most important role in the growth of graphene: high temperature was preferred in order to obtain less defective sites. The optimum synthesis parameters were suggested as 1000 °C, 30 min duration time, 20 °C/min temperature rising ramp, and 1200 sccm argon gas flow rate. Post heat treatment was proved to be a feasible way to improve the crystallinity of graphite. Amorphous carbon was removed or converted into crystalline graphite under heat and oxygen. FTIR spectra confirmed the covalent linkages between carbon encapsulated copper nanoparticles and N-methyl-2-pyrrolidone and polyvinylpyrrolidone, indicating a successful functionalization. This study has presented a homogeneous carbon encapsulated copper nanoparticles solution in water and ethanol, and paved ways for further functionalization of CECNs. Advisors/Committee Members: H. Michael Barnes (chair), Jilei Zhang (chair), El Barbary M. Hassan (committee member), Dragica Jeremic Nikolic (committee member).

▼ The essential components in the synthesis of high-quality II-VI and IV-VI QDs have remained largely unchanged for 20 years; typically employing tertiary phosphine chalcogenides and metal salts as the reactive precursors. The reaction mechanism responsible for monomer nucleation was investigated. Pure tertiary phosphine selenide sources (e.g. trioctylphosphine selenide (TOPSe)) were surprisingly found to be unreactive with metal carboxylates and incapable of yielding QDs. Rather, small quantities of secondary phosphines are entirely responsible for the nucleation of QDs at low temperatures (< 200 °C); their low concentrations account for poor synthetic conversion yields. Also, we have reported the synthesis and characterization of novel, ultra-small PbSe magic-sized nanoclusters (MSCs). Unlike the syntheses of high-quality semiconductor nanoparticles, the MSC synthesis is straightforward, occurring at room temperature in air over several hours. MSCs have core diameters < 2 nm and fluoresce in the near-infrared (900 nm) with remarkable quantum efficiencies consistently greater than 50%. The relatively slow growth of MSCs allows for a significant scale up of reaction volumes. Transfer to aqueous solvents has also been demonstrated, establishing MSCs as a potential new fluorophore for applications in biological imaging. Ostwald ripening represents a major contributor to semiconductor quantum dot growth under a wide range of experimental conditions. Quantum dot concentrations and diameters are shown to change dramatically at temperatures widely encountered in growth and processing procedures. Further, data is provided that supports the role of ligand in ripening and an attempt is made to understand its chemical pathway. Finally, kinetic data shows that PbSe QDs ripen significantly faster than CdSe QDs. Density functional calculations agree with the experimental results and provide insight into their origin. A secondary phosphine chalcogenide (DPPSe) was investigated as a potential anion source for the production of both PbSe and CdSe QDs. Unfortunately, reactions were found only capable of producing MSCs, albeit with quantitative conversion yields. Observation of reaction kinetics emphasized the importance of controlling nucleation rates for size-control. Methodologies are presented that effectively separate nucleation from growth; which allow for the predictable and reproducible synthesis of specific-sized QDs.

▼ In Chapter 1, we study affirmative action in school choice. School choice programs aim to give students the option to choose their school. At the same time, underrepresented minority students should be favored to close the opportunity gap. A common way to achieve this is to have a majority quota at each school, and to require that no school be assigned more majority students than its majority quota. An alternative way is to reserve some seats at each school for the minority students, and to require that a reserve seat at a school be assigned to a majority student only if no minority student prefers that school to her assignment. However, fair rules based on either type of affirmative action suffer from a common problem: a stronger affirmative action may hurt some minority students without benefiting another minority student. First, we show that this problem is pervasive: the problem disappears only if the minority students "mostly" have priority over the majority students. Then, we uncover the root of this problem: for some minority students, treating them as minority students does not benefit them, but possibly hurts other minority students. We propose a new assignment rule (Modified deferred acceptance with minority reserves), which treats such minority students as majority students, achieves affirmative action, and never hurts a minority student without benefiting another minority student. In Chapter 2, we consider implementing a socially optimal allocation when there are responsible agents. A set of tasks is to be allocated among agents. There is an optimal allocation of the tasks, which is not observable by the designer and which does not necessarily depend on the preferences of the agents over tasks. We allow for "responsible agents" whose preferences over allocations are responsive to the optimal allocation in the following way: given two allocations such that she is indifferent between her assignments, if all the agents who are assigned their optimal tasks at the former allocation are still assigned their optimal tasks at the latter allocation, and there is an agent who is not assigned her optimal task in the former but is assigned her optimal task in the latter allocation, then the responsible agent prefers the latter allocation to the former. In this context, we analyze eliciting the optimal allocation via game forms. We show that if the designer knows that there are at least three responsible agents, even if the identities of the responsible agents are not known, the optimal allocation can be elicited. The framework we introduce allows studying problems where some agents care about the goal of the designer besides their self interest. In Chapter 3, we consider Nash-implementation of the "no-envy" solution. Without any assumptions on the structure of the resources to be distributed, by only assuming preferences to be complete, we show that a simple game form, which resembles the "Divide-and-Choose" procedure, Nash-implements the no-envy solution. Our result extends a result by Thomson (2005), and it is…

▼ A new eddy-feedback mechanism, the Selective Absorption Mechanism (SAM), to explain the block maintenance is proposed. In this mechanism which is based on the vortex-vortex interaction, that is, the interaction mechanism of a blocking anticyclone and synoptic eddies with the same polarity, a blocking anticyclone actively and selectively absorbs synoptic anticyclones. The blocking anticyclone thus supplied with low potential vorticity can last for a long time against dissipation. The SAM is verified by two main analyses. The first is to examine ten real cases of blocking using trajectory analysis. Trajectories are calculated by tracing parcels originating from synoptic anticyclones and cyclones upstream of blocking. Parcels starting from anticyclones are attracted and absorbed by the blocking anticyclone, whereas parcels from cyclones are repelled by it and attracted by the blocking cyclone if it exists. The second analysis is to conduct numerical experiments using the nonlinear equivalentbarotropic potential vorticity equation with some different conditions, which are in shape and amplitude of blocking and in variabilities (displacement and strength) of stormtracks. These experiments indicate that the SAM effectively works to maintain the blocking without depending on these conditions. These results show that the SAM is the general maintenance mechanism of blocking. Next, some possible applications of the SAM are mentioned. First, the SAM is applied to a quantitative estimation of the interaction between a blocking anticyclone and synoptic anticyclones in real situations. The effect of the forcing by the interaction between the blocking anticyclone and synoptic ones is estimated. The response to this forcing in a barotropic model well explains the pattern and amplitude of real blocking. Thus, the interaction with synoptic anticyclones plays an important role in the block maintenance. Second, the SAM is adapted to a block in summer when the activity of synoptic eddies is thought to be the minimum during a year. However, it is found that the variability of potential vorticity is climatologically the maximum in summer, which implies that the SAM can also be adopted to summer blocking. Then, a case study for the 2010 summertime blocking is performed for investigating whether the SAM actually contributes to the maintenance of this blocking. Through the trajectory analysis, an analysis of ensemble forecast data, and a barotropic model experiment, the maintenance of this summertime blocking is found to be also largely contributed by the selective absorption of synoptic anticyclones. Thus, even in summer, the SAM can be essential for the maintenance of blocking. Advisors/Committee Members: 伊藤, 久徳.
