description: Recall that Janson showed that if the edges of the complete graph $K_n$ are assigned exponentially distributed independent random weights, then the expected length of a shortest path between a fixed pair of vertices is asymptotically equal to $(\log n)/n$. We consider analogous problems where edges have not only a random length but also a random cost, and we are interested in the length of the minimum-length structure whose total cost is less than some cost budget. For several classes of structures, we determine the correct minimum length structure as a function of the cost-budget, up to constant factors. Moreover, we achieve this even in the more general setting where the distribution of weights and costs are arbitrary, so long as the density $f(x)$ as $x\to 0$ behaves like $cx^γ$ for some $γ\geq 0$; previously, this case was not understood even in the absence of cost constraints. We also handle the case where each edge has several independent costs associated to it, and we must simultaneously satisfy budgets on each cost. In this case, we show that the minimum-length structure obtainable is essentially controlled by the product of the cost thresholds.

description: In this work we theoretically study pairing in two-dimensional Fermi gases, a system which is experimentally accessible using cold atoms. We start by deriving the mean-field pairing gap equation for a coordinate-space potential with a finite interaction range, and proceed to solve this numerically. We find that for sufficiently short effective ranges the answer is identical to the zero-range one. We then use Diffusion Monte Carlo to evaluate the total energy for many distinct particle numbers; we employ several variational parameters to produce a good ground-state energy and then use these results to extract the pairing gap across a number of interaction strengths in the strongly interacting two-dimensional crossover. Extracting the gap via the odd-even energy staggering, our microscopic results can be used as benchmarks for other theoretical approaches.

public goods experiment

description: Ostracism is practiced by virtually all societies around the world as a means of enforcing cooperation and excluding members who show anti-social behaviors or attitudes. In this paper, we use a public goods experiment to study whether groups choose to implement an institution that allows for the exclusion of members. We distinguish between a costless exclusion institution and a costly exclusion institution that, if chosen, reduces the endowment of all players. We also provide a comparison with an exclusion institution that is exogenously imposed upon groups. A significant share of the experimental groups choose the exclusion institution, even when it comes at a cost, and the support for the institution increases over time. Average contributions to the public good are significantly higher when the exclusion option is available, not only because low contributors are excluded but also because high contributors sustain a higher cooperation level under the exclusion institution. Subjects who vote in favor of the exclusion institution contribute more than those who vote against it, but only when the institution is implemented. These results are largely inconsistent with standard economic theory but can be better explained by assuming heterogeneous groups in which some players have selfish and others have social preferences.

description: This paper explores the innovative multi-stakeholder cooperative structure of Sandhills Farm to Table Food Hub and how this business utilizes an innovative organizational structure to connect producers, consumers, and workers to each other and the community. Evaluating SF2T’s structure demonstrates how a multi-stakeholder cooperative benefits, incentivizes, and equalizes the three stakeholder classes. We also analyze current business activities and comment on barriers to the cooperative’s future growth and expansion. Finally, the paper highlights the multiple benefits the cooperative provides to the community and how their structure and activities enable the cooperative to address current objectives and plan for future goals.

Printing as Practice: Innovation and Imagination in the Making of Tibetan Buddhist Sacred Texts in California

description: This thesis offers an exploration of how one brings a Tibetan sacred text to being — and to voice — in the unfamiliar, and perhaps unlikely, landscape of Northern California. Through 16 months’ fieldwork with a Nyingma Buddhist community based in Berkeley, California I ask how the production of the sacred is undertaken here by American volunteers who are largely neophytes to Tibetan Buddhism. Against a backdrop of the history of Tibetan textual production — largely populated by masters, monastics, and artisans — I explore what kind of work (both physical and imaginative) American volunteers must undertake in order to render themselves effective creators of the sacred in this American industrial setting. Drawing on current research that explores the adaptive capacities of Tibetan Buddhist traditional practices, I will offer a new facet to this flexibility through an investigation of the ways these texts and their surrounding practices are creatively deployed to meet the needs of their American makers. In this work I follow the sacred objects through their entangled physical and social creation in the various branches of this California community, from the construction of spaces ripe for sacred work, through fundraising, printing, and finally to the distribution of texts to the Tibetan monastic community in Bodh Gaya, India. In the conclusion I return to the question of how an American volunteer becomes an effective creator of a Tibetan Buddhist sacred text in Berkeley California, contributing a unique and rich case to the study of diasporic Tibetan text production. Ultimately, I will demonstrate that the very practice of creating and deploying Tibetan sacred texts offers a frame through which volunteers come to re-interpret and re-shape their spatial and temporal landscape. This dissertation seeks to bridge often disparate fields of study, allowing encounters between (and contributions to) such bodies of work as: the anthropological study of making, craft, and innovation; media and religious practice; the affective temporality of sacred relics; and the cross-culturally unique, agentive qualities of books.

description: We have investigated the physical effects of the Dzyaloshinskii-Moriya (DM) interaction in copper benzoate. In the low field limit, the spin gap is found to vary as $H^{2/3}\ln ^{1/6}(J/μ_BH_s)$ ($H_s$: an effective staggered field induced by the external field $H$)in agreement with the prediction of conformal field theory, while the staggered magnetization varies as $H^{1/3}$ and the $\ln^{1/3}(J/μ_BH_s)$ correction predicted by conformal field theory is not confirmed.The linear scaling relation between the momentum shift and the magnetization is broken. We have determined the coupling constant of the DM interaction and have given a complete quantitative account for the field dependence of the spin gaps along all three principal axes, without resorting to additional interactions like interchain coupling. A crossover to strong applied field behavior is predicted for further experimental verification.

description: Since the turn of the millennium, China opened up internationally both in terms of its current account (trade) and its capital account, even though the opening of the latter happened de facto, not de jure. With respect to China being Africa's largest trading partner and developing investor in combination with its desire for African natural resources, we embark on an analysis of the impact of several categories of Chinese capital flows to African economies on the bilateral real exchange rate. We conduct a panel data analysis by means of a Hausman-Taylor-estimation over the period 2003-2016. Our results suggest that capital flows from China to Africa in the form of mainly economic cooperation projects, but also FDI contribute to an appreciation of the local currencies vis _a vis the RMB, while no such effect appears for aid flows from China. The former two categories may pose a risk of Dutch Disease effects. Since many African countries have pegged their currencies to the Euro, and the Renminbi abandoned its peg to the US Dollar over the sample period, valuation effects of capital flows must be interpreted in this context.

description: Eukaryotic genomes contain a large number of pyrimidine-purine rich regions and such regions can assume varied DNA conformations, including triple-stranded structures. These structures have fascinated scientists because of their considerable therapeutic applications. These structures have also profound implications in the field of nanotechnology as they can be used to develop DNA-based nanostructures and materials. Therefore, for any application, it is important to understand the formation of triplex structures, both in quantitative and qualitative terms. A combination of gel electrophoresis, UV-thermal denaturation and circular dichroism (CD) spectroscopy was used to investigate the formation of inter- as well as intramolecular triplex, in pyrimidine motif at BOLF1 gene of human herpesvirus 4 (HH4) genome. This gene codes for inner tegument protein, which plays crucial roles in viral replication. The said oligopurine•oligopyrimidine duplex was targeted via a designed triple helix forming oligopyrimidine nucleotide (TFO) in intermolecular as well as intramolecular fashion. Our studies revealed that intramolecular triplex formation takes place at acidic as well as at neutral pH; whereas low pH is required for its intermolecular version. This comparative study between inter- and intramolecular triplex allowed us to demonstrate that intramolecular structure is more stable to its intermolecular counterpart. Numerous models for mono-, bi- and trimolecular structures adopted by these DNA sequences have been suggested. This report adds to our existing knowledge about DNA triple helical structures.

description: Real returns to farm operators have been at the highest level since 1973. However, indications from the USDA and Federal Open Market Committee are that returns are not projected to remain at those levels and interest rates will rise in the next decade. This paper evaluates the potential impact on repayment risk of three interest rates, three levels of leverage, and eight deviations from a base situation. Results indicate as the level of leverage and interest rate increased, the business became more susceptible to repayment risk, but even at moderate interest rates, increasing levels of leverage should be viewed with caution.

description: We present our observations of the galaxy UGS 5600 with a long-slit spectrograph (UAGS) and a multi-pupil field spectrograph (MPFS) using the 6-m telescope at Special Astrophysical Observatory. Radial-velocity fields of the stellar and gaseous components were constructed for the central region and inner ring of the galaxy. We proved the existence of two almost orthogonal kinematic subsystems and conclude that UGC 5600 is a galaxy with an inner polar ring. In the circumnuclear region, we detected noncircular stellar motions and suspected the existence of a minibar. The emission lines are shown to originate in H II regions. We estimated the metallicity from the intensity ratio of the [NII]$\lambda6583$ and \Ha lines to be nearly solar, which rules out the possibility that the polar ring was produced by the accretion of gas from a dwarf companion.

description: Regulation of gene expression is an essential process for all living organisms. Transcriptional regulation, associated with chromatin, is governed by: (1) DNA sequence, which creates regulatory sites (promoters, enhancers and silencers), where sequence motifs and features (e. g. CpG) can attract transcription factors (TFs) and influence chromatin structure or RNA polymerase II (Pol II) binding, initiation and elongation; (2) non-sequence, epigenetic factors - histone modifications, TF binding, chromatin remodelling (histone placement, eviction and reconstitution), and non-coding RNA regulation. These factors interact with each other, creating a complex network of interactions. In this thesis I describe computational studies of heterochromatin factors in regulation of gene and repeat expression, an analysis of active regulatory elements, and global analyses of big datasets in C. elegans. I first show that a team of heterochromatin factors - HPL-2/HP1, LIN-13, LIN-61, LET-418/Mi-2, and H3K9me2 histone methyltransferase MET-2/SETDB1 - collaborates with piRNA and nuclear RNAi pathways to silence repetitive elements and protect the germline. I also found that the TACBGTA motif is particularly enriched on repeats and heterochromatin factors binding sites, and that repeat elements are derepressed in the soma during normal C. elegans ageing. I then describe the work on active regulatory regions. I show that CFP-1/CXXC1 binds CpG dense, nucleosome depleted promoters and, along SET-2, is required for H3K4me3 deposition at these loci. Using expression profiling I determined that the majority of CFP-1 binding targets are not significantly mis-regulated in cfp-1 mutants, but are weakly upregulated in bulk analyses. I also show that CFP-1 functionally interacts with the Sin3S/HDAC complex. In cfp-1 mutant I observed both loss and gain of SIN-3 binding, depending on chromatin context. Finally, I performed a data driven study on a large collection of ChIP-seq profiles using non-parametric sparse factor analyses (NSFA) and compared it to other, unsupervised machine learning algorithms. This study uncovered interactions and structure in genomic datasets. In addition, I present a collection of computational tools and methods I developed to facilitate processing, storage, retrieval, annotation, and analyses of large datasets in genomics.

description: The 2019-novel coronavirus (nCoV) has caused a global health crisis by causing coronavirus disease-19 (COVID-19) pandemic in the human population. The unavailability of specific vaccines and anti-viral drug for nCoV, science demands sincere efforts in the field of drug design and discovery for COVID-19. The novel coronavirus main protease (SARS-CoV-2 Mpro) play a crucial role during the disease propagation, and hence SARS-CoV-2 Mpro represents as a drug target for the drug discovery. Herein, we have applied bioinformatics approach for screening of chemical compounds from Indian spices as potent inhibitors of SARS-CoV-2 main protease (PDBID: 6Y84). The structure files of Indian spices chemical compounds were taken from PubChem database or Zinc database and screened by molecular docking, by using AutoDock-4.2, MGLTools-1.5.6, Raccoon virtual screening tools. Top 04 hits based on their highest binding affinity were analyzed. Carnosol exhibited highest binding affinity -8.2 Kcal/mol and strong and stable interactions with the amino acid residues present on the active site of SARS-CoV-2 Mpro. Arjunglucoside-I (-7.88 Kcal/mol) and Rosmanol (-7.99 Kcal/mol) also showed a strong and stable binding affinity with favourable ADME properties. These compounds on MD simulations for 50ns shows strong hydrogen-bonding interactions with the protein active site and remains stable inside the active site. Our virtual screening results suggest that these small chemical molecules can be used as potential inhibitors against SARS-CoV-2 Mpro and may have an anti-viral effect on nCoV. However, further validation and investigation of these inhibitors against SARS-CoV-2 main protease are needed to claim their candidacy for clinical trials.

Soft X-ray emission lines from photoionized accretion discs: constraints on their strength and width

description: We consider the properties of soft X-ray emission lines in the reprocessed emission from a photoionized accretion disc. Observations of these lines will be important in determining the ionization state and metallicity of the innermost regions of active galaxies. Calculations of reflection from a constant-density disc with an ionization parameter between 250 and 1000 erg cm/s show that emission from O VIII Lyαwill dominate the soft X-ray emission spectrum. There is also significant emission from C VI, N VII, O VII, as well as Fe XVII--XIX. As the ionization parameter is increased these lines become weaker and are broadened by Compton scattering. Significantly increasing the O abundance primarily strengthens the O VII line, making it as large or larger than the O VIII line. The nitrogen and carbon lines are quite weak with equivalent widths (EWs) <30 eV, even with an increase in the N abundance. A hydrostatic ionized disc model has a more realistic density structure and shows a similar spectrum, but with the lines weaker and broader. This is a result of the hot ionized skin at the surface of the disc. We apply these results to the controversial claim of soft X-ray relativistic lines in the XMM-Newton spectrum of MCG--6-30-15. We are unable to find a situation where O VIII has the required EW without substantial emission from O VII. Furthermore, Compton scattering results in the blue wing of the O VIII line to be much broader than the << 10 eV drop observed in the data. We conclude that soft X-ray accretion disc lines will, in general, be weak and broad features and are unlikely to produce sharp edges in the data.

description: Nonlinear sigma model (NLSM) based on the coset $\text{SU}(N)\times \text{SU}(N)/\text{SU}(N)$ exhibits several intriguing features at the leading ${\cal O}(p^2)$ in the derivative expansion, such as the flavor-kinematics duality and an extended theory controlling the single and triple soft limits. In both cases the cubic biadjoint scalar theory plays a prominent role. We extend these features in two directions. First we uncover a new extended theory for $\text{SO}(N+1)/\text{SO}(N)$ NLSM at ${\cal O}(p^2)$, which is a cubic bifundamental/biadjoint scalar theory. Next we provide evidence for flavor-kinematics dualities up to ${\cal O}(p^4)$ for both $\text{SU}(N)$ and $\text{SO}(N)$ NLSM's. In particular, we introduce a new duality building block based on the symmetric tensor $δ^{ab}$ and demonstrate several flavor-kinematics dualities for 4-point amplitudes, which precisely match the soft blocks employed to soft-bootstrap the NLSM's up to ${\cal O} (p^4)$.

Two problems face the livestock producer in this case study: 1) should the producer purchase replacement females or keep existing unbred females; and 2) should the producer expand his operation in terms of both land and cows. Students are asked to estimate a net present value (NPV) for both investment decisions. These NPVs should account for risk as prices in the beef cattle sector are anything but certain.

description: This paper analyzes the cost efficiency impacts of adopting biotechnology-enhanced soybean varieties for a set of Kansas farms from 1993 to 2011 using cost indices estimated from linear programming techniques. The cost efficiency indices are then coupled with survey data about the adoption of biotechnology-enhanced soybean varieties to provide a comparative analysis over time and across different quartiles of the sample. Results indicate that cost efficiency is not likely to decline on average with the adoption of these soybean varieties, but may increase for more efficient farms through a number of different benefits associated with adoption.

description: We study antiferromagnetism and single-particle properties in the two-dimensional half-filled Hubbard model at low temperature. Collective spin fluctuations are governed by a non-linear sigma model that we derive from the Hubbard model for any value of the Coulomb repulsion. As the Coulomb repulsion increases, the ground state progressively evolves from a Slater to a Mott-Heisenberg antiferromagnet. At finite temperature, we find a metal-insulator transition between a pseudogap phase at weak coupling and a Mott-Hubbard insulator at strong coupling.

description: We search for Ricci flat, Kähler geometries which are asymptotic to the cone whose base is the space T^{11} by working out covariantly constant spinor equations. The metrics we find are singular in the interior and introducing parallel D3-branes does not form regular event horizons cloaking the naked singularities. We also work out a supersymmetric ansatz involving only the metric and the 5-form field corresponding to D3-branes wrapping over the non-trivial 2-cycle of T^{11}. We find a system of first-order equations and argue that the solution has an event horizon and the ADM mass per unit volume diverges logarithmically.

Essays in Networks and Behaviour

description: This dissertation, submitted for the degree of Doctor of Philosophy, is comprised of three essays on networks and human behaviour. The first studies the capacity for some agent in a network, who we term the 'principal', to ensure the robustness of their network to potentially disruptive external shocks. Agents susceptible to shocks may invest in contingencies but have insufficient incentive to do so from the perspective of the principal. We derive results on the cost to the principal of overcoming the resulting moral hazard problem. We focus first on the case where agents can only write contracts with their immediate neighbors, finding that costs are strictly increasing in the longest path in the network away from the principal when the probability of shocks is low. However, we also find that for a fixed longest path away from the principal, a secondary 'responsibility' effect can cause costs to be lower when the average distance away from the principal is higher. We extend our model to allow the principal to contract directly with all agents but with additional information processing costs. We consider applications to supply chain robustness to natural disasters and employee adherence to safety regulations in a firm. The second essay develops a model of demand led innovation in supply chains and studies the general equilibrium effects of demand shocks on R&D expenditure. It is found that when no final good producers share suppliers, a positive demand shock will weakly increase innovation in all firms. However, with common suppliers, negative pecuniary externalities may reduce R&D expenditure in some firms. The final essay was produced in collaboration with Dr. Matthew Elliott. It proposes a new model of individual choice as a Markovian decision process over emotional states. This approach allows for economic decisions to depend upon both an individual's current emotional state as well as introspection about how choices will affect their future emotional state. The generality of this framework is shown formally before demonstrating its efficacy in dealing with specific applications drawn from empirical findings in psychology and neuroscience. Specifically, the role of frustration in gambling is explored, along with the role of angry emotional responses in generating inefficiency and delay in negotiation and bargaining.

description: We present a unified approach to quantum teleportation in arbitrary dimensions based on the Wigner-function formalism. This approach provides us with a clear picture of all manipulations performed in the teleportation protocol. In addition within the framework of the Wigner-function formalism all the imperfections of the manipulations can be easily taken into account.

description: Iron-sulfur (Fe-S) clusters are one of the earliest known metal complexes in biological molecules. Suf system is one of the Fe-S biogenesis pathways. SufA belongs to the Suf pathway. It is an A-type carrier protein that transfers Fe-S clusters from the scaffold to target proteins. Structural studies were performed for the Suf pathway protein, SufA, in order to explore the conformational changes that probably aid in the transfer of Fe-S clusters to target proteins. Three-dimensional (3D) structure of Plasmodium falciparum (Pf) SufA homodimer was obtained by homology modeling using 3D structure of Escherichia coli (Ec) SufA as template. Molecular dynamics (MD) simulation of Pf SufA and Ec SufA homodimers followed by trajectory and pocket analyses were carried out. A co-ordinated displacement of the homodimeric chains in the interfacial region, resembling a swinging trapeze-like movement was observed. Potential involvement of this swinging trapeze-like movement of the residues belonging to the interfacial region has been proposed as a probable mechanism that assists in the transfer of Fe-S cluster from SufA to apo proteins. This was substantiated by protein-protein interaction studies in Pf SufA by performing molecular docking of 3D conformations of Pf SufA obtained from MD trajectory at every 1 ns interval with Pf ferredoxin.

description: We demonstrate a versatile, rotational-state dependent trapping scheme for the ground and first excited rotational states of $^{23}$Na$^{40}$K molecules. Close to the rotational manifold of a narrow electronic transition, we determine tune-out frequencies where the polarizability of one state vanishes while the other remains finite, and a magic frequency where both states experience equal polarizability. The proximity of these frequencies of only 10 GHz allows for dynamic switching between different trap configurations in a single experiment, while still maintaining sufficiently low scattering rates.

Stability of Topological States and Crystalline Solids

description: From the alignment of magnets to the melting of ice, the transition between different phases of matter underpins our exploitation of materials. Both a quantum and a classical phase can undergo an instability into another state. In this thesis, we study the stability of matter in both contexts: topological states and crystalline solids. We start with the stability of fractional quantum Hall states on a lattice, known as fractional Chern insulators. We investigate, using exact diagonalization, fractional Chern insulators in higher Chern bands of the Harper-Hofstadter model, and examine the robustness of their many-body energy gap in the effective continuum limit. We report evidence of stable states in this regime; comment on two cases associated with a bosonic integer quantum Hall effect; and find a modulation of the correlation function in higher Chern bands. We next examine the stability of molecules using variational and diffusion Monte Carlo. By incorporating the matrix of force constants directly into the algorithms, we find that we are able to improve the efficiency and accuracy of atomic relaxation and eigenfrequency calculation. We test the performance on a diverse selection of case studies, with varying symmetries and mass distributions, and show that the proposed formalism outperforms existing restricted Hartree-Fock and density functional theory methods. Finally, we analyze the stability of three-dimensional crystals. We note that for repulsive Coulomb crystals of point nuclei, cubic systems have a zero matrix of force constants at second order. We investigate this by constructing an analytical model in the tight-binding approximation, and present a phase diagram of the most stable crystal structures, as we tune core and valence orbital radii. We reconcile our results with calculations in the nearly free electron regime, as well as current research in condensed matter and plasma physics.

A Hierarchy of Anyon Models Realised by Twists in Stacked Surface Codes

description: Braiding defects in topological stabiliser codes can be used to fault-tolerantly implement logical operations. Twists are defects corresponding to the end-points of domain walls and are associated with symmetries of the anyon model of the code. We consider twists in multiple copies of the 2d surface code and identify necessary and sufficient conditions for considering these twists as anyons: namely that they must be self-inverse and that all charges which can be localised by the twist must be invariant under its associated symmetry. If both of these conditions are satisfied the twist and its set of localisable anyonic charges reproduce the behaviour of an anyonic model belonging to a hierarchy which generalises the Ising anyons. We show that the braiding of these twists results in either (tensor products of) the S gate or (tensor products of) the CZ gate. We also show that for any number of copies of the 2d surface code the application of H gates within a copy and CNOT gates between copies is sufficient to generate all possible twists.
