description: Depression is an important risk factor for many chronic health conditions, especially cardiovascular disease. Depression can affect the biological pathways that increase disease risk, and it can worsen the symptoms of chronic disease by decreasing self-care behaviors. However, just as it is important to identify risk factors of chronic illnesses, it is equally as important to identify protective factors. One potential protective factor may be sense of purpose in life, or the idea that life has meaning and direction. Purpose in life has been linked to lower incidence of certain chronic diseases and has also been negatively correlated with depressive symptoms. A sense of purpose in life could buffer the effect of depression by serving as a motivator for health-promoting behaviors. This study investigated whether high sense of purpose in life influences the long-term associations between depression, number of chronic illnesses, and cardiovascular risk. Participants were adults who participated in a national, longitudinal study called Midlife Development in the United States (MIDUS). Results indicated that purpose in life did not moderate the relationship between depression and number of chronic health conditions, depression and number of cardiovascular diagnoses, or depression and subjective heart attack risk at either MIDUS timepoint. The findings from this study suggest that purpose in life may not be the appropriate moderator for these relationships, but other variables of psychological well-being, such as autonomy, may be better suited to influence the association of depression and chronic disease.
Nonanticommutative Deformation of N=4 SYM Theory: The Myers Effect and Vacuum States

description: We propose a deformation of ${\cal N}=4$ SYM theoery induced by nonanticommutative star product. The deformation introduces new bosonic terms which we identify with the corresponding Myers terms of a stack of D3-branes in the presence of a five-form RR flux. We take this as an indication that the deformed lagrangian describes D3-branes in such a background. The vacuum states of the theory are also examined. In a specific case where the U(1) part of the gauge field is nonvanishing the (anti)holomorphic transverse coordinates of the brane sit on a fuzzy two sphere. For a supersymmetric vacuum the antiholomorphic coordinates must necessarily commute. However, we also encounter non-supersymmetric vacua for which the antiholomorphic coordinates do not commute.

description: We describe the structure and implementation of a radiation hydrodynamic solver for MANGA, the moving-mesh hydrodynamics module of the large-scale parallel code, Charm N-body GrAvity solver (ChaNGa). We solve the equations of time dependent radiative transfer using a reduced speed of light approximation following the algorithm of Jiang et al (2014). By writing the radiative transfer equations as a generalized conservation equation, we solve the transport part of these equations on an unstructured Voronoi mesh. We then solve the source part of the radiative transfer equations following Jiang et al (2014) using an implicit solver, and couple this to the hydrodynamic equations. The use of an implicit solver ensure reliable convergence and preserves the conservation properties of these equations even in situations where the source terms are stiff due to the small coupling timescales between radiation and matter. We present the results of a limited number of test cases (energy conservation, momentum conservation, dynamic diffusion, linear waves, crossing beams, and multiple shadows) to show convergence with analytic results and numerical stability. We also show that it produces qualitatively the correct results in the presence of multiple sources in the optically thin case.

title: The affective development of biology students in further education. The construction and evaluation of a test related to O- and A-level courses in biology, with particular reference to the affective domain. Use of the test to obtain diagnostic and predictive information.
Creators: name: Bentley, Gerald Ian
Publisher: name: The Open University
Year: 1980

description: The thesis is divided into three parts. In Part One, the literature relating to affective characteristics and science education is reviewed. In Part Two, the theory and measurement of effective characteristics are discussed. Part three describes the design and use of a questionnaire to measure the affective development of further education students in the biological sciences, A taxonomic model of affective development forms the basis of the instrument. The results provide evidence that supports the validity of a taxonomic model of affective development. Students studying for GCE A-level in the biological sciences are shorn to have reached higher states of affective development than GCE 0-level students. 'Affective Profiles' can provide a useful graphic representation of the level of affective development reached by individual students and such profiles can, in conjunction with cognitive data, aid in the prediction of academic success. The level of affective development reached by groups of students is found to be related to gender and vocational grouping. Females obtain higher scores at the lower levels of the taxonomy, but males are more likely to obtain high scores at the higher levels. Students tend to reach higher levels of affective development if they are following courses which are vocationally related to biology. The study has not identified any clear pattern of relationship between affective development and cognitive development, which would allow academic success to be predicted from a knowledge of affective development alone.

description: In recent biomedical scientific problems, it is a fundamental issue to integratively cluster a set of objects from multiple sources of datasets. Such problems are mostly encountered in genomics, where data is collected from various sources, and typically represent distinct yet complementary information. Integrating these data sources for multi-source clustering is challenging due to their complex dependence structure including directional dependency. Particularly in genomics studies, it is known that there is certain directional dependence between DNA expression, DNA methylation, and RNA expression, widely called The Central Dogma. Most of the existing multi-view clustering methods either assume an independent structure or pair-wise (non-directional) dependency, thereby ignoring the directional relationship. Motivated by this, we propose a copula-based multi-view clustering model where a copula enables the model to accommodate the directional dependence existing in the datasets. We conduct a simulation experiment where the simulated datasets exhibiting inherent directional dependence: it turns out that ignoring the directional dependence negatively affects the clustering performance. As a real application, we applied our model to the breast cancer tumor samples collected from The Cancer Genome Altas (TCGA).

Self-assembly of the gyroid cubic mesophase: lattice-Boltzmann simulations

Publisher: name: arXiv
Year: 2003
Subjects: subject: Soft Condensed Matter (cond-mat.soft)

description: We present the first simulations of the self-assembly kinetics of the gyroid cubic mesophase using a Boltzmann transport method. No macroscopic parameters are included in the model and three-dimensional hydrodynamics is emergent from the microscopic conservation laws. The self-assembly arise from local inter-particle interactions in an initially homogeneous, phase segregating binary fluid with dispersed amphiphile. The mixture evolves in discrete time according to the dynamics of a set of coupled Boltzmann-BGK equations on a lattice. We observe a transient microemulsion phase during self-assembly, the structure function peaks and direct-space imaging unequivocally identifying the gyroid at later times. For larger lattices, highly ordered subdomains are separated by grain boundaries. Relaxation towards the ordered equilibrium structure is very slow compared to the diffusive and microemulsion-assembling transients, the structure function oscillating in time due to a combination of Marangoni effects and long-time-scale defect dynamics.

Bounce from Inflation

description: We construct a class of viable bouncing models that are conformally related to cosmological inflation. There are three main difficulties in constructing such a model: (i) A stable (attractor) solution, (ii) A non-singular bounce, and (iii) to bypass the no-go theorem that states that simultaneously maintaining the observational bounds on the tensor-to-scalar ratio and the non-Gaussian scalar spectrum are not possible. We show that a non-minimal coupling of the scalar field helps to bypass these difficulties and provides a viable bouncing model with a naturally occurring reheating epoch briefly after the bouncing phase.

Essays on Uncertainty and Macroeconomic Dynamics
Creators: name: Levy, Jeffrey A.
Publisher: name: American University
Year: 2023

description: In this dissertation I examine economic uncertainty, particularly from the perspective of disaggregation below the national level. In part one I outline the building of news-based uncertainty measures for all 50 US states plus Washington DC. I analyze different search specifications, finding that the simplest set of terms involving one group for "economy" and one group for "uncertainty" has the highest resolution, while yielding similar results to more focused news searches, including one similar to the ubiquitous policy search from Baker et al. (2016), and an alternative specification designed to eliminate false positives. I also explore the differences between two other national uncertainty measures - the VIX stock market volatility index from the Chicago Board Options Exchange, and the unforecastable macroeconomic factors from Jurado et al. (2015). In part two, I build upon the analysis of the state uncertainty measures begun in part one. I show that analyzing uncertainty at the national level obscures significant state-level variation, with state-to-national uncertainty correlations ranging from 0.124 to 0.913, while some inter-state uncertainty correlations even turn negative. I then show that VAR analysis using state-level unemployment figures yields impulse response functions that are remarkably similar to existing national-level uncertainty research, with 92% of states exhibiting a rise in unemployment that peaks near 12 months after an uncertainty shock, then overshoots the starting point for a time. Finally, in part three I attempt to get at the causal effects of an uncertainty shock, as VAR analysis is unable to do, by applying a difference-in-difference framework to the natural experiment of military base closures. I look at the 1991, 1993, 1995, and 2005 rounds of the Base Realignment and Closure (BRAC) process, whereby the government moves military jobs in and out of bases through a process that is, at least initially, heavily insulated from confounding economic indicators and political influence. This creates asymmetric and exogenous uncertainty shocks in places with different military employment, which I use to show that a one-percentage point higher military share of employment causes a tenth of a percentage point higher unemployment rate in a given Metropolitan Statistical Area (MSA) during a BRAC round.
title: Oxidative Folding of a Cystine Knot Protein: the Amaranthus α-amylase Inhibitor
Creators: name: Čemažar, Maša
Publisher: name: The Open University
Year: 2003

description: The work described in this thesis is concerned with the study of the oxidative folding pathway of a cystine knot protein, Amaranthus a-amylase inhibitor (AAI). The data presented in the thesis are obtained with a combination of different biochemical and biophysical techniques, with an emphasis on NMR spectroscopy.
 Chapter 1 gives a short introduction to the structural and functional superfamilies of the protein in question. Additionally, it outlines the protein folding problem, with an emphasis on oxidative folding, and stresses the importance of studying such pathways in small proteins. Chapter 2 covers both the basis of experimental techniques and the details of experimental methods used in the study. The remaining four chapters (3, 4, 5 and 6) are results and discussion chapters. Each one deals with a specific aspect of the study of the oxidative folding pathway of Amaranthus a-amylase inhibitor.
 Chapter 3 presents the results from an improved solid phase peptide synthesis approach, which increased the overall yield of peptide synthesis and recovered a greater amount of AAI after the refolding step. In Chapter 4 the intermediate species that appear on the oxidative folding pathway are identified and characterised in terms of their disulfide content. An illustration of the structural features of the main folding intermediate (MFI) with NMR, photo-CID NP and computer modelling techniques is given in Chapter 5. In Chapter 6 the kinetic process of the oxidative folding of Amaranthus a-amylase inhibitor is studied at the level of a single disulfide species and at the level of a single amino acid residue.
 The novelty of this thesis is two-fold. First, from the point of view of biological interest, this is the first time that oxidative folding intermediates with non-native disulfide bridges between adjacent cysteine residues are observed. Second, from the point of view of development of biophysical methods, the first application of time-resolved NMR and photo-CIDNP spectroscopy to a complete oxidative folding process is described.

description: This paper tries to establish whether there are variations of the central wavelengths or the profile shapes of diffuse interstellar bands (DIBs) and whether these variations are caused by different physical parameters of translucent clouds. For this purpose we used spectra of two stars seen through two different single clouds: HD34078 (AE Aur) \& HD73882 acquired using two different instruments: the MIKE spectrograph, fed with the 6.5 m Magellan telescope at Las Campanas Observatory, and the UVES, fed with the 8 m Kueyen telescope at the Paranal observatory. The wavelength displacements of the DIBs at 6196, 6203, 6376, 6379 and 6614 Å with respect to the well known interstellar atomic and molecular lines (K{\sc i} and CH) have been measured. The mentioned shift is seemingly absent in the DIBs at 4726, 4964, 4763, and 4780 Å. In addition the considered profiles may show (in HD34078) extended red wings. The observed phenomena are likely related to physical parameters of intervening clouds (rotational temperatures of molecular species) and may help in the identification of the DIB carriers.

description: Recent developments of the sources of intense and ultrashort X-ray pulses stimulate theoretical studies of phenomena occurring on ultrafast timescales. In the present study, spin-flip dynamics in transition metal complexes triggered by sub-femtosecond X-ray pulses are addressed theoretically using a density matrix-based time-dependent configuration interaction approach. The influence of different central metal ions and ligands on the character and efficiency of spin-flip dynamics is put in focus. According to our results, slight variations in the coordination sphere do not lead to qualitative differences in dynamics, whereas the nature of the central ion is more critical. However, the behavior in a row of transition metals demonstrates trends that are not consistent with general expectations. Thus, the peculiarities of spin dynamics have to be analyzed on a case-to-case basis.
title: Factors affecting the distribution, abundance and chick survival of the Lapwing (Vanellus vanellus)
Creators: name: Sheldon, Robert David
Publisher: name: The Open University
Year: 2003

description: This thesis was conducted to investigate Lapwing Vanellus vanellus breeding ecology and its relationship with the modern agricultural landscape. Scientific research has suggested that changes in modern agricultural practices have been responsible for the declines in a suite of farmland bird species, including the Lapwing. Fieldwork was conducted over the breeding seasons of 1999 and 2000 over a range of farm locations in Shropshire and Staffordshire, with additional supplementary data obtained from a parallel study undertaken in Cambridgeshire. This research assessed the effectiveness of the ‘Lapwing Option’ (Option IB) in the pilot Arable Stewardship agrienvironment scheme. A total of 225 nests were located and monitored. There were few detectable effects of agricultural variables on clutch size, egg volume, intra-clutch egg size variation or hatching rates. Cultivation dates stipulated by Option IB avoided the peak nesting period for this population of Lapwings. At the start of the breeding season Lapwings selected a wide variety of crop types as nest sites, however, crop choice declined as the season progressed, with the majority of replacement nests on Option IB and spring crops. Lapwings were shown to select nest-sites that had a short, patchy sward structure. Nest survival was high, yet the most common causes of nest failure were predation and losses to agricultural operations. Losses on stubbles and spring cereals were primarily associated with agricultural operations. Nests that were greater than 50m distant fi*om a field boundary had a greater probability of survival than nests that were less than 50m away. Chick weight and condition were shown to be positively correlated with mean egg volume. There was no evidence that any of the measured agricultural variables had an effect on chick growth, condition or survival. Results show that chick survival was low and productivity estimates were less than that required to maintain population stability. Chicks that were known to have fledged had a better body condition index than chicks that had been predated. It was found that the variety of crop types used as foraging habitat declined as the season progressed. Option IB, set- aside and sugar beet were the latest crops that could be utilised by chicks. A variety of invertebrate taxa were found in faecal samples of chicks, with earthworms, beetles and spiders the most frequent. There was a positive relationship between the number of earthworms in the diet and chick age, chick condition and daily growth rates. Option IB appears to have a number of benefits for breeding Lapwing, although it does not address low chick survival. Further research is required to elucidate the key factors affecting chick survival and to develop management prescriptions to enhance breeding productivity.

description: Lies can have a negating impact on governments, companies, and the society as a whole. Understanding the dynamics of lying is therefore of crucial importance across different fields of research. While lying has been studied before in well-mixed populations, it is a fact that real interactions are rarely well-mixed. Indeed, they are usually structured and thus best described by networks. Here we therefore use the Monte Carlo method to study the evolution of lying in the sender-receiver game in a one-parameter family of networks, systematically covering complete networks, small-world networks, and one-dimensional rings. We show that lies which benefit the sender at a cost to the receiver, the so-called black lies, are less likely to proliferate on networks than they do in well-mixed populations. Honesty is thus more likely to evolve, but only when the benefit for the sender is smaller than the cost for the receiver. Moreover, this effect is particularly strong in small-world networks, but less so in the one-dimensional ring. For lies that favor the receiver at a cost to the sender, the so-called altruistic white lies, we show that honesty is also more likely to evolve than it is in well-mixed populations. But contrary to black lies, this effect is more expressed in the one-dimensional ring, whereas in small-world networks it is present only when the cost to the sender is greater than the benefit for the receiver. Lastly, for lies that benefit both the sender and the receiver, the so-called Pareto white lies, we show that the network structure actually favors the evolution of lying, but this only when the benefit for the sender is slightly greater than the benefit for the receiver. In this case again the small-world topology acts as an amplifier of the effect, while other network topologies fail to do the same.

description: Over the recent years, the pharmaceutical field has been under significant pressure to adapt to the principles of green chemistry. The industry is facing the challenge of environmental protection and securing people's health while sustaining its fundamental goals of efficiency and selectivity optimization. In this work, the reaction processes optimization has been acheived through the microfluidic approach to the widely used aldol condensation reaction. In accordance with the green chemistry principles, we have found that the best conditions include aqueous ethanol solvent and easily available amino acids used as catalysts. Asymmetric aldol condensation of para-nitrobenzaldehyde with cyclohexanone catalyzed by L-tert-Leu under microfluidic conditions provided the product with high yield and diastereoselectivity (anti/syn = 28:1) and 98% enantiomeric excess. The microfluidic reactor process, compared to the classical batch method (in a flask), provides comparable product yield, while the reaction time was reduced by an order of magnitude. It should be noted that this approach allows to carry out the reactions at low (below zero) temperatures with greater enantioselectivity.

description: We present a model of (double) kinetic theory which paves the way to describe matter in a Double Field Theory background. Generalized diffeomorphisms acting on double phase space tensors are introduced. The generalized covariant derivative is replaced by a generalized Liouville operator as it happens in relativistic kinetic theory. The section condition is consistently extended and the closure of the generalized transformations is still given by the C-bracket. In this context we propose a generalized Boltzmann equation and compute the moments of the latter, obtaining an expression for the generalized energy-momentum tensor and its conservation law.

description: We report results of a photometric survey with the WIYN telescope for carbon stars in the M 31 dwarf spheroidal (dSph) companions And III, And V, And VI, and And VII, as well as in the relatively isolated Local Group dSph Cetus. We find three carbon-star candidates in And VII and one carbon star in each And VI and Cetus. Comparing the carbon star content with other Local Group dwarf galaxies, we argue against the presence of substantial intermediate-age stellar populations in the all of the galaxies surveyed with the exception of And VII. We discuss these results in the context of the origin of the Andromeda dSphs and conclude that these are ancient galaxies, most of which ceased star formation long before the main merger events in M31. The M31 dSphs therefore show less diversity in star formation histories than the Galactic dSph companions, or the M31 dE companions, as illustrated by NGC147 which was surveyed as a calibration object. All of our dSph targets except And V have candidate carbon stars below the tip of the RGB, which resemble CH stars found in globular clusters. We estimate that 0.3% of stars in the dSphs are CH stars, presumably as a result of C pollution from a binary companion. Comparisons with CH star frequencies in globular clusters could constrain the impact of dense environments on the frequency of this form of binary star evolution.

title: THE APPLICATION OF REMOTE SENSING TECHNIQUES IN HYDROLOGY
Creators: name: Blyth, Kenneth
Publisher: name: The Open University
Year: 1980

description: REMOTE SENSING, which may be simplistically defined as ’the collection and interpretation of emitted or reflected radiation from a body’, offers the potential for accurate interpolation of surface data and even for its direct measurement on scales ranging from local to world wide. This dissertation has been written primarily for the hydrologist, engineer, environmentalist or student who needs to measure changes either in space or time of hydrological variables such as water quality, but who has little practical knowledge of remote sensing or how it may be of assistance to him. It may be regarded as a reference document which, as a result of internal cross referencing and comprehensive external subject referencing, should enable the reader to acquire a background knowledge of remote sensing theory which is relevant to his interests, to understand the advantages and difficulties of applying remote sensing techniques to his measurement problem and to obtain further information about remote sensing applications which have already been undertaken within his field of interest. The dissertation centres on the hydrological situation in England and Wales by initially outlining the structure of their water industries. The main hydrological measurement objectives in terms of water resources, water supply, effluent disposal and flood prediction and warning are identified and some advantages of incorporating remote sensing into hydrological measurement programmes are suggested. The physical theory of remote sensing is described and the main methods of collecting and analysing remotely sensed data are given. A topic by topic analysis of the most suitable ways of tackling specific hydrological measurement problems through the use of remote sensing is made and the dissertation concludes with an assessment of the likely future use of remote sensing in hydrological measurement programmes in general

Essays on Uncertainty and Macroeconomic Dynamics
Creators: name: Levy, Jeffrey A.
Publisher: name: ProQuest
Year: 2023

description: In this dissertation I examine economic uncertainty, particularly from the perspective of disaggregation below the national level. In part one I outline the building of news-based uncertainty measures for all 50 US states plus Washington DC. I analyze different search specifications, finding that the simplest set of terms involving one group for "economy" and one group for "uncertainty" has the highest resolution, while yielding similar results to more focused news searches, including one similar to the ubiquitous policy search from Baker et al. (2016), and an alternative specification designed to eliminate false positives. I also explore the differences between two other national uncertainty measures - the VIX stock market volatility index from the Chicago Board Options Exchange, and the unforecastable macroeconomic factors from Jurado et al. (2015). In part two, I build upon the analysis of the state uncertainty measures begun in part one. I show that analyzing uncertainty at the national level obscures significant state-level variation, with state-to-national uncertainty correlations ranging from 0.124 to 0.913, while some inter-state uncertainty correlations even turn negative. I then show that VAR analysis using state-level unemployment figures yields impulse response functions that are remarkably similar to existing national-level uncertainty research, with 92% of states exhibiting a rise in unemployment that peaks near 12 months after an uncertainty shock, then overshoots the starting point for a time. Finally, in part three I attempt to get at the causal effects of an uncertainty shock, as VAR analysis is unable to do, by applying a difference-in-difference framework to the natural experiment of military base closures. I look at the 1991, 1993, 1995, and 2005 rounds of the Base Realignment and Closure (BRAC) process, whereby the government moves military jobs in and out of bases through a process that is, at least initially, heavily insulated from confounding economic indicators and political influence. This creates asymmetric and exogenous uncertainty shocks in places with different military employment, which I use to show that a one-percentage point higher military share of employment causes a tenth of a percentage point higher unemployment rate in a given Metropolitan Statistical Area (MSA) during a BRAC round.
The Logotropic Dark Fluid: Observational and Thermodynamic Constraints

description: We have considered a spatially flat, homogeneous and isotropic FLRW Universe filled with a single fluid, known as logotropic dark fluid (LDF), whose pressure evolves through a logarithmic equation of state. We use the recent Pantheon SNIa and cosmic chronometer datasets to constrain the parameters of this model, the present fraction of dark matter $Ω_{m0}$ and the Hubble constant $H_0$. We find that the mean values of these parameters are $Ω_{m0}=0.288\pm 0.012$ and $H_{0}=69.652\pm 1.698~{\rm km/s/Mpc}$ at the $1σ$ CL. We also find that the LDF model shows a smooth transition from the deceleration phase to acceleration phase of the universe in the recent past. We notice that the redshift of this transition $z_{t}=0.706\pm 0.048$ ($1σ$ error) and is well consistent with the present observations. Interestingly, we find that the Universe will settle down to a $Λ$CDM model in future and there will not be any future singularity in the LDF model. Furthermore, we notice that there is no significant difference between the LDF and $Λ$CDM models at the present epoch, but the difference (at the percent level) between these models is found as the redshift increases. We have also studied the generalized second law of thermodynamics at the dynamical apparent horizon for the LDF model with the Bekenstein and Viaggiu entropies.

Decomposing the U.S. Great Depression : how important were loan supply shocks?
Creators: name: Breitenlechner, Max

Publisher: name: American University
Year: 2023

description: We measure the contributions of loan supply shocks and other macroeconomic shocks to U.S. output dynamics during the Great Depression. Using structural vector autoregressions, we impose sign restrictions to identify shocks. We find that loan supply shocks contributed negatively to output growth between 1931 and 1933, at the same time as the U.S. experienced several waves of banking crises. Thus, our results support the view that disruptions in credit availability contributed to the depth and length of the Great Depression. We also find that adverse aggregate demand and monetary policy shocks were important factors in the downturn.
Role of connectivity in congestion and decongestion in networks

description: We study network traffic dynamics in a two dimensional communication network with regular nodes and hubs. If the network experiences heavy message traffic, congestion occurs due to finite capacity of the nodes. We discuss strategies to manipulate hub capacity and hub connections to relieve congestion and define a coefficient of betweenness centrality (CBC), a direct measure of network traffic, which is useful for identifying hubs which are most likely to cause congestion. The addition of assortative connections to hubs of high CBC relieves congestion very efficiently.

description: Annular structures in proto-planetary discs, such as gaps and rings, are now ubiquitously found by high-resolution ALMA observations. Under the hypothesis that they are opened by planets, in this paper we investigate how the minimum planet mass needed to open a gap varies across different stellar host masses and distances from the star. The dependence on the stellar host mass is particularly interesting because, at least in principle, gap opening around low mass stars should be possible for lower mass planets, giving us a look into the young, low mass planet population. Using dusty hydrodynamical simulations, we find however the opposite behaviour, as a result of the fact that discs around low mass stars are geometrically thicker: gap opening around low mass stars can require more massive planets. Depending on the theoretical isochrone employed to predict the relationship between stellar mass and luminosity, the gap opening planet mass could also be independent of stellar mass, but in no case we find that gap opening becomes easier around low mass stars. This would lead to the expectation of a {\it lower} incidence of such structures in lower mass stars, since exoplanet surveys show that low mass stars have a lower fraction of giant planets. More generally, our study enables future imaging observations as a function of stellar mass to be interpreted using information on the mass vs. luminosity relations of the observed samples.

Loop-erased random walk as a spin system observable

description: The determination of the Hausdorff dimension of the scaling limit of loop-erased random walk is closely related to the study of the one-point function of loop-erased random walk, i.e., the probability a loop-erased random walk passes through a given vertex. Recent work in the theoretical physics literature has investigated the Hausdorff dimension of loop-erased random walk in three dimensions by applying field theory techniques to study spin systems that heuristically encode the one-point function of loop-erased random walk. Inspired by this, we introduce two different spin systems whose correlation functions can be rigorously shown to encode the one-point function of loop-erased random walk.
