description: Starting from any operad P, one can consider on one hand the free operad on P, and on the other hand the Baez--Dolan construction on P. These two new operads have the same space of operations, but with very different notions of arity and substitution. The main result of this paper is that the incidence bialgebras of the two-sided bar constructions of the two operads constitute together a comodule bialgebra. The result is objective: it concerns comodule-bialgebra structures on groupoid slices, and the proof is given in terms of equivalences of groupoids and homotopy pullbacks. Comodule bialgebras in the usual sense are obtained by taking homotopy cardinality. The simplest instances of the construction cover several comodule bialgebras of current interest in analysis. If P is the identity monad, then the result is the Faà di Bruno comodule bialgebra (dual to multiplication and substitution of power series). If P is any monoid $Ω$ (considered as a one-coloured operad with only unary operations), the resulting comodule bialgebra is the dual of the near-semiring of $Ω$-moulds under product and composition, as employed in Écalle's theory of resurgent functions in local dynamical systems. If P is the terminal operad, then the result is essentially the Calaque--Ebrahimi-Fard--Manchon comodule bialgebra of rooted trees, dual to composition and substitution of B-series in numerical analysis (Chartier--Hairer--Vilmart). The full generality is of interest in category theory. As it holds for any operad, the result is actually about the Baez--Dolan construction itself, providing it with a new algebraic perspective.

description: We investigate the existence and stability of solitons in an optical waveguide equipped with a Bragg grating (BG) in which nonlinearity contains both cubic and quintic terms. The model has straightforward realizations in both temporal and spatial domains, the latter being most realistic. Two different families of zero-velocity solitons, which are separated by a border at which solitons do not exist, are found in an exact analytical form. One family may be regarded as a generalization of the usual BG solitons supported by the cubic nonlinearity, while the other family, dominated by the quintic nonlinearity, includes novel ``two-tier'' solitons with a sharp (but nonsingular) peak. These soliton families also differ in the parities of their real and imaginary parts. A stability region is identified within each family by means of direct numerical simulations. The addition of the quintic term to the model makes the solitons very robust: simulating evolution of a strongly deformed pulse, we find that a larger part of its energy is \emph{retained} in the process of its evolution into a soliton shape, only a small share of the energy being lost into radiation, which is opposite to what occurs in the usual BG model with cubic nonlinearity.

description: The comparison of different models (the Ore, spur and blob models) of positronium (Ps) formation is presented. Because in molecular media Ps is formed in the terminal positron blob and not in an ordinary spur, the application of the blob model seems to be the most adequate. We extend this model for consideration of the Ps formation in the presence of external electric field ($<100$ kV/cm). In the simplified limiting case, this approach provides a formula similar to the Onsager one for the geminate recombination probability. The influence of ion-electron recombination and other intrablob processes on Ps formation is taken into account. The role of quasifree positronium in Ps formation process is discussed.
I monstra umani nel Prodigiorum liber di Giulio Ossequente. Una prospettiva interdisciplinare sulla deformit� del corpo nella tradizione latina

description: Obiettivo della ricerca � osservare il ruolo della deformit� del corpo umano nel Prodigiorum liber di Giulio Ossequente: egli reperisce nella storia liviana una serie di eventi portentosi di varia natura e li cataloga nella sua epitome mantenendo il procedere annalistico della fonte. All?estrema sintesi con cui si descrivono i corpi degli uomini mostruosi, in un testo spesso avaro di dettagli riguardanti tali fenomeni, si prova a porre rimedio attraverso un confronto piuttosto puntuale tra i casi ossequentiani di mostruosit� e altre occorrenze di anomalia corporea riferite da autori latini e greci anche anteriori e posteriori, oltre che in un unico prezioso caso con la fonte liviana viceversa perduta nella parte riguardante l?arco di tempo di cui l?epitome -anch?essa mutila- si occupa. Tale metodo comparativo ha consentito di individuare alcuni specifici casi di deformit� patologica, tra i quali uno dei pi� frequenti e certamente il pi� significativo � l?androginia, e di osservarli in prospettiva interdisciplinare sotto differenti punti di vista: anzitutto letterario, con lo scopo di intrecciare i molteplici passi d?interesse tratti da un corpus di fonti ampio ed eterogeneo; lessicale-semantico, per mettere preventivamente in luce i termini afferenti all?ambito della mostruosit� e i loro significati specifici; giuridico, al fine di riconoscere qualche aspetto della perduta normativa repubblicana per i casi di anomalia fisica, anche in paragone con le leggi di et� imperiale; medico-scientifico, con l?obiettivo di realizzare della casistica raccolta una ricognizione oggettiva e di riconoscere in essa, laddove possibile, i caratteri di qualche specifica patologia. Per questo scopo, si � effettuato un confronto con l?opera rinascimentale di Ulisse Aldrovandi dotata di un sorprendente apparato iconografico che ricalca precisamente i casi di Ossequente, con il quale si inaugura la scienza teratologica proprio a partire da un?edizione del Prodigiorum liber.

description: The rapid diffusion of information and the adoption of social behaviors are of critical importance in situations as diverse as collective actions, pandemic prevention, or advertising and marketing. Although the dynamics of large cascades have been extensively studied in various contexts, few have systematically examined the impact of network topology on the efficiency of information diffusion. Here, by employing the linear threshold model on networks with communities, we demonstrate that a prominent network feature---the modular structure---strongly affects the speed of information diffusion in complex contagion. Our simulations show that there always exists an optimal network modularity for the most efficient spreading process. Beyond this critical value, either a stronger or a weaker modular structure actually hinders the diffusion speed. These results are confirmed by an analytical approximation. We further demonstrate that the optimal modularity varies with both the seed size and the target cascade size, and is ultimately dependent on the network under investigation. We underscore the importance of our findings in applications from marketing to epidemiology, from neuroscience to engineering, where the understanding of the structural design of complex systems focuses on the efficiency of information propagation.
Authentication and Traceability of valuable food regional excellence production from Piemonte and Liguria

description: The most important Italian food are those with a label of quality; their high commercial value is due to some organoleptic characteristics that are the result of particular things; traditional processing, environmental conditions, soil composition, cultivar. These peculiarities make Italian products unique, but they inspire a high number of food frauds: the most widespread are the false declaration of provenance, or use of raw matters different than those declared. The legislative framework only concerns the documentation checks and actually there is very few legislation on food controls based on a scientific methods. This produces wide fraud phenomena, because paper documentation can be easy falsified. To stop the counterfeits of Made in Italy it is necessary to develop analytical methods to recognize the origin of a food. This is possible through the use of two different approaches, the Traceability that concerning the possibility to link a foodstuff to its provenance soil, and relating the raw matter with the finished product and Authentication that regards the ability to recognize a food among other similar products, but with different characteristics of lesser value, for example a different production technique, different possibility to perform studies with the use of the Trace Elements and, the Lanthanides. These elements do not seem to enter in the vegetable metabolism, but they are absorbed passively, and in this way they represent a fingerprint of the territory of origin. Through the use of the Elemental Analysis, with ICP-MS system and a chemometric approach, we developed an analytical method for Traceability and Authentication, and we tested them on some valuable Italian foodstuffs, mainly products in the Piemonte and Liguria region: milk and cream (Piemonte), Olive Oil obtained from Taggiasca cultivar (Liguria), Mushrooms (Piemonte and Liguria), Rice (Piemonte) and Wine must (Piemonte).

description: Die Aufmerksamkeitsdefizit-Hyperaktivitätsstörung (ADHS) ist eine neurobiologische Störung, die sich in Konzentrationsstörungen in Verbindung mit Hyperaktivität und impulsivem Handeln zeigt. Diese Masterarbeit gibt einen Überblick über den aktuellen wissenschaftlichen Stand der ADHS von Erwachsenen, insbesondere der ADHS von Frauen und zeigt historische, medizinische, therapeutische und diagnostische Aspekte der ADHS. Sie klärt auf, wie sich die ADHS-Wender-Utah Diagnosekriterien für Erwachsene im Erleben der vier Komponenten des sexualwissenschaftlichen Modells Sexocorporel zeigen und welche Ressourcen und Herausforderungen die ADHS in der Paarsexualität mit sich bringt. In einer qualitativen Untersuchung wurden vier Interviews mit Paaren geführt, um das Erleben der ADHS von ADHS-diagnostizierten Frauen in Bezug zur Paarsexualität zu ermitteln. Die anschliessende Auswertung der qualitativen Inhaltsanalyse nach Philipp Mayring (2015) hat gezeigt, dass sich insbesondere eine hohe Ablenkbarkeit durch äussere Reize in der Paarsexualität negativ auswirkt und sich durch Reizüberflutung entstandener Stress in einem konstant erhöhten Muskeltonus manifestiert. Sexuell erregendste Begegnungen in der Paarsexualität von ADHS-diagnostizierten Frauen ergeben sich durch die Abgabe von Verantwortung und Kontrolle an den Partner/die Partnerin.

description: Some recent neutron scattering works on CeRhIn5 and Ce2RhIn8, together with related resistivity and specific heat measurements, are summarized. In spite of its layered crystal structure, CeRhIn5 is shown to be 3-dimensional both magnetically and in transport. We also find that the Fisher-Langer behavior is closely followed in CeRhIn5. This may circumvent the Kondo lattice model and support applying established Fermi-liquid superconductivity theory to heavy fermion superconductors.

description: Sexualisierte Gewalt und der Umgang damit stellen ein gesamtgesellschaftliches Problem dar. Von staatlicher Seite wird auf die Problematik mittels schärferer Gesetze reagiert. Diese institutionellen Interventionen dienen allerdings nicht allen Menschen gleichermaßen als unterstützende und schützende Struktur. Aus intersektional feministischer Perspektive überprüft, zeigen die staatlichen Sicherheitsmaßnahmen deutliche Leerstellen auf. Anstatt alle Betroffenen zu stärken, werden für hilfesuchende marginalisierte Personengruppen Gewalt und Diskriminierung innerhalb staatlicher Institutionen eher verstärkt. Aus diesem Grund haben sich außerstrafrechtliche und selbstorganisierte Umgangsstrategien mit sexualisierter Gewalt entwickelt, die mit bereits vorhandenen feministischen Konzepten kombiniert und mittlerweile auch in Deutschland angewendet werden. In der vorliegenden Masterarbeit werden die Prinzipien von Community Accountability und Transformativ Justice mittels einer qualitativen Interviewforschung untersucht, wobei der Schwerpunkt auf der Arbeit mit gewaltausübenden Personen liegt. Die mit Hilfe der thematischen Analyse (nach Braun und Clarke 2006) ermittelten Ergebnisse zeigen gruppenbezogene und strukturelle Voraussetzungen für die transformative Arbeit mit gewaltausübenden Personen und weisen gleichermaßen auf Schwierigkeiten und Herausforderungen für die praktische Arbeit hin. Zudem zeigt die Studie, dass transformative Arbeit in Deutschland innerhalb einer weißen linkspolitischen Szene mit feministisch - polizeikritischem Selbstverständnis praktiziert wird. Weiterführend können die Ergebnisse der vorliegenden Arbeit als Grundlage zur kritischen Auseinandersetzung mit Barrieren der Zugänglichkeit außerstrafrechtlicher Konzepte und der Aneignung von BIPoC Strategien in mehrheitlich weißen Kontexten genutzt werden.

description: Within the solar system, approximate realizations of the three-body problem occur when a comet approaches a planet while being affected mainly by such a planet and the Sun, and this configuration was investigated by Tisserand within the framework of Newtonian gravity. The exact relativistic treatment of the problem is not an easy task, but the present paper develops an approximate calculational scheme which computes for the first time the tiny effective-gravity correction to the equation of the surface for all points of which it is equally advantageous to regard the heliocentric motion as being perturbed by the attraction of Jupiter, or the jovicentric motion as being perturbed by the attraction of the Sun. This analysis completes the previous theoretical investigations of effective-gravity corrections to the Newtonian analysis of three-body systems, and represents an intermediate step towards relativistic effects on cometary motions.

We investigate thermodynamic properties for various dilaton coupling constants and find that thermodynamic properties change at a critical dilaton mass $m_{d,crit}$. For $m_{d}\geq m_{d,crit}$, the black hole becomes an extreme solution for a nonzero horizon radius $r_{h,ex}$ as the Reissner-Nordström black hole. However, if $m_{d}$ is nearly equal to $m_{d,crit}$, there appears a solution of smaller horizon radius than $r_{h,ex}$. For $m_{d}

description: The Epstein--Glaser type T-subtraction introduced by one of the authors in a previous paper is extended to the Lorentz invariant framework. The advantage of using our subtraction instead of Epstein and Glaser's standard W-subtraction method is especially important when working in Minkowski space, as then the counterterms necessary to keep Lorentz invariance are simplified. We show how T-renormalization of primitive diagrams in the Lorentz invariant framework directly relates to causal Riesz distributions. A covariant subtraction rule in momentum space is found, sharply improving upon the BPHZL method for massless theories.

Using instructional videos as a reference, we selected a list of common manipulation motions seen in cooking activities grouped into similar motions based on several trajectory and contact attributes. Manipulation codes are then developed based on the taxonomy attributes to represent the manipulation motions. The manipulation taxonomy is then used for comparing motion data in the Daily Interactive Manipulation (DIM) data set to reveal their motion similarities.

description: The method for determination the microscopic surface tension $σ(R)$ of nanobubbles is developed based on the new elaboration of the positronium bubble model. In contrast to existing structureless Ps bubble models, our version contains experimentally known molecular characteristics of liquids. The relationship, similar to Tolman's equation, between $σ(R)$ and the radius $R$ of the Ps bubble is derived on a microscopic basis. Numerical values for $σ(R)$ are determined for a large number of liquids and liquified gases. The results are in agreement with the theoretical expectations and independent evaluations, available in literature.

description: This paper describes the application of geostatistics to weather index insurance in order to systematically analyze spatial basis risk inherent in index insurance contracts. The notion of spatial autocorrelation is in general overlooked by index insurance practitioners, but has profound implications for the effectiveness of the insurance offered. The analysis shows that it is possible to offer contracts from multiple weather stations to a single farmer, and that doing so will likely reduce the basis risk from a single contract. The two major implications of the paper are 1) that index insurance should be offered in more flexible contracts that allow farmers to hedge their production according to their perceptions of basis risk and their appetites for risk, and 2) the tradeoff between local (yield) correlation and spatial correlation needs to be more carefully considered, as it may even be better to offer contracts with poor yield correlation if they can include more spatial coverage.

description: Since agricultural production is significantly and directly influenced by weather, financial weather products based on temperature have been developed in recent decades. The crop producer can now hedge adverse temperature outcomes in either the exchange market or the over-the-corner (OTC) market. However, exchange-traded contracts invariably carry geographic basis risk because of differences in the market-quoted and local temperature outcomes. OTC option contracts, on the other hand, are at risk of possible default by the counterparty. Therefore, a portfolio combining OTC with exchange-traded contracts could potentially be used by crop producers to reduce overall income risk. In this paper, we examine the performances of these three alternative hedging strategies on the uncertainty of crop producer’s income. Using a case study for western Canada, we find that a portfolio that combines OTC and exchange-traded contracts provides a most effective means of reducing potential risks, compared with stand-alone OTC contracts or exchange-market contracts because of their higher default and geographic basis risks, respectively.

description: The importance of aspirations for economic decision making has recently gained attention in the field of development economics. It’s been suggested that aspirations are formed from observing the status of one’s peers, and a failure of aspirations may result in a tendency to behave in a myopic and seemingly suboptimal manner. In this paper we provide the first known empirical test of the aspirations failure theory articulated in Appadurai (2004) and Ray (2006) using a unique dataset from rural Nepal. We ask two questions: (1) Does the current status of others in my aspirations window predict my own aspirations? (2) Is the aspirations gap correlated with future-oriented behavior? Our analysis suggests that the readily observable assets of one’s peers are quite important for one’s own wealth aspirations. However, the income of one’s peers, which is more readily hidden, is not important for one’s aspirational income. We also find evidence in support of Ray’s hypothesis that the aspirations gap is what ultimately drives future-oriented behavior, rather than aspirations or current standard of living.

description: This study asks the question: is the US using food safety regulations illegitimately, that is as a non-tariff barrier to trade rather than to manage food safety risks, specifically in the context of agri-food imports from Canada? Data on US import refusals of three categories of fruits, vegetables and nuts, cereal products, and seafood are used as a proxy for stringency and enforcement of US food safety regulations, with a negative binomial generalized linear model being employed to determine the significance of range of food safety risk and other less legitimate drivers of US food safety regulations. Key variables used to capture political influence on US food safety regulations are lobbying contributions, changes in import prices, and the occurrence of countervailing investigations. While US border rejections for these commodities are largely explained by food safety risks, there is evidence of political influence, with qualitative and quantitative difference across the commodities.

description: The method which allows for asymptotic expansion of the one-loop effective action W=ln det A is formulated. The positively defined elliptic operator A= U + M^2 depends on the external classical fields taking values in the Lie algebra of the internal symmetry group G. Unlike the standard method of Schwinger - DeWitt, the more general case with the nondegenerate mass matrix M=diag(m1,m2,...) is considered. The first coefficients of the new asymptotic series are calculated and their relationship with the Seeley-DeWitt coefficients is clarified.

title: Investigating the structure, regulation and interactions of KANK proteins
Creators: name: Khan, Rejina Begum
Publisher: name: University of Kent

description: Many cellular activities rely on interactions between cells and the extracellular matrix (ECM) and these attachments are mediated by the integrin family of transmembrane receptors. Talin, a cytoplasmic adapter protein, activates integrin by binding to the cytoplasmic tails and ultimately couples integrin to the actin cytoskeleton. Once the adhesion has formed, talin can act as a mechanosensitive signalling hub and recruit additional proteins in a force-dependent manner. KANK proteins, via direct interaction with talin and with the kinesin KIF21A, mediate the connection of these integrin-based adhesions with dynamic microtubules. A complex of proteins termed the cortical microtubule stabilising complex (CMSC) is recruited upon talin-KANK interaction which stabilises microtubules in the vicinity of adhesions. The talin-KANK connection results in mechanosensitive crosstalk between the actin and microtubule cytoskeletons, contributes to microtubule polarity, and provides a mechanism for turnover of adhesions during cell migration. In this thesis, a combination of structural, biochemical and biophysical approaches were used to broaden our understanding of KANK proteins. With a recurring focus on identifying similarities and differences between the four mammalian KANK isoforms, particularly within specific domains, we discover some key isoform-specific differences in terms of the ankyrin repeat domains including dimeric propensity that is unique to KANK4, characterise a novel interaction between the KN and ankyrin repeat domains of KANKs and narrow down on the required binding surface on the KN domain, and identify a novel interaction between DYNLL2 and an intrinsically disordered region in KANK1. Additionally, as part of this work, two novel crystal structures of KANK ankyrin repeat domains were solved and solution NMR data providing structural information for DYNLL2 was collected. Ultimately, the work in this thesis explores some novel properties of KANKs and provides the foundations for an array of further study into this family of proteins, allowing the deduction of their structures and functions - either related to their role as linkers between actin filaments and microtubules or potentially in other unrelated and yet undiscovered cellular contexts.
Three-dimensional flux states as a model for the pseudogap phase of transition metal oxides

description: We propose that the pseudogap state observed in the transition metal oxides can be explained by a three-dimensional flux state, which exhibits spontaneously generated currents in its ground state due to electron-electron correlations. We compare the energy of the flux state to other classes of mean field states, and find that it is stabilized over a wide range of $t$ and $δ$. The signature of the state will be peaks in the neutron diffraction spectra, the location and intensity of which are presented. The dependence of the pseudogap in the optical conductivity is calculated based on the parameters in the model.

title: Forced migration disentangled - How do armed conflicts lead to displacement?
Creators: name: Ozaltin, Duygu
Publisher: name: University of Kent
Year: 2021

description: In this dissertation, I investigate the factors behind variances in forced migration flows and try to develop a deeper understanding of the causal relationship between political violence and forced displacement by building comprehensive models, which account for political, social and economic factors. I theorize that the degree to which civilians are targeted during episodes of political violence directly affects the number of forced migration flows, leading to an original methodological approach based on a large-n, a country survey and semi-structured interview analyses. The results from a global analysis for the period of 1970-2016 bring a neglected association between terrorism and forced displacement into spotlight, while I do not find evidence in support of the increasingly popular 'economic refugee' argument. The large-n analysis also confirms that rising intensity of violence and declining civil and political liberties are powerful drivers of forced migration. In addition, a survey study of migration intentions in post-Saddam Iraq confirms the ambiguous effect of economic status on the process of shaping migration intentions. The survey analysis also shows that migration intentions do not cede with prospects of an ending conflict. Findings from Iraq further indicate that potential refugees are generally well educated contrary to popular assumptions about forced migrants. Concluding the study with interviews of refugees in the UK provides an opportunity to further interrogate the reasons behind remaining while other leave and demonstrates the impact of individual agency in the decision making process. The interviews show that exposure to political violence leads to almost identical experiences and impacts on the participants despite their various backgrounds, which led them to their ultimate decision of leaving. When asked about economic reasons that may have contributed to their decision to move, none of the participants found such factors to be relevant. On the contrary, most participants in this study held relatively better economic and social status in their country of origin.

description: Diese Bachelorarbeit hat sich damit auseinandergesetzt, wie sich die Arbeit mit einem systemischen Kinderbuch positiv auf die Bewältigung von Trennungserfahrungen von Kindern im Kindergartenalter auswirken kann. Dabei wurde weiter betrachtet, wie eine kreative systemische Geschichte erstellt werden kann, welche Entwicklungsschritte und Inhalte dabei beachtet werden müssen und welche Vorteile, Anwendungsgebiete und Grenzen diese Methodik hat. In diesem Zusammenhang wird das Beratungsfeld lösungsorientierten Arbeiten mit Kindern näher betrachtet untersucht, im speziellen die Methodik: systemische Geschichten bzw. Märchen. In Anwendung dieser Methodik wurde eine systemische Geschichte in Form eines kleinen Kinderbuches wurde entwickelt, präsentiert und analysiert. Im Ergebnis ist diese Bachelorarbeit zu dem Schluss gekommen, dass sich die Arbeit mit einem systemischen Kinderbuch sinnvoll und positiv auf die Bewältigung von Trennungserfahrungen von Kindern im Kindergartenalter auswirken kann. Jedoch haben sich auch Grenzen dieser Methodik gezeigt wie z.B., dass grundlegende Literacy-Erfahrungen nötig sind, um Kinder mit Literatur bei der Bewältigung von Problemen anzusprechen.
Magnetocaloric effect in molecular spin clusters and their assemblies: model exact and Monte Carlo studies

description: We study the magnetocaloric effect (MCE) in spin clusters of six spins with site spins $s=1$, $3/2$ and $2$ for different exchange anisotropies. We also study MCE in an assembly of spin clusters, on a chain, a 2-D square lattice and 3-D cubic lattice with spin-dipolar interactions using a Monte Carlo method in spin-1 systems. We compute the magnetic Grüneisen parameter $Γ_H$, and study its dependence on exchange anisotropy and spin-dipolar interaction. With increase of exchange anisotropy the maxima in $Γ_H$, shifts to higher magnetic fields and becomes a sharp singularity. The first maximum in $Γ_H$ shifts to lower fields as we increase spin-dipolar interaction. The behaviour of $Γ_H$ on applied magnetic field is also reflected in the magnetic entropy of the systems. The first maximum in $Γ_H$ also shifts to lower magnetic field strength as the magnitude of the site spin increases. We also show the dependence of $Γ_H$ on dimensionality of the lattice for a fixed lattice constant.
Plane waves in periodic, quadratically nonlinear slab waveguides: stability and exact Fourier structure

description: We consider the propagation of broad optical beams through slab waveguides with a purely quadratic nonlinearity and containing linear and nonlinear long-period quasi-phase-matching gratings. An exact Floquet analysis on the periodic, plane-wave solution shows that the periodicity can drastically alter the growth rate of the modulational instability but that it never completely removes the instability. The results are confirmed by direct numerical simulation, as well as through a simpler, approximate theory for the averaged fields that accurately predicts the low-frequency part of the spectrum.

description: The aim of this study is to investigate the influence of geometry on the performance of signalcontrolled road junctions under fixed-time and system D traffic responsive signal control by using 16 experimental scenarios with several different traffic and geometric characteristics. In the estimated log-linear models for delay per unit of time, the principal effects of lane width and turning radii were as expected. The effect on delay of the interaction between lane width and turning radii was found to be of substantial importance at light traffic flow, while the interaction between turning radii and signal control was found to play a significant role at medium traffic flow.

description: We study an interacting $λ\,ϕ^4_{\star}$ scalar field defined on Snyder-de Sitter space. Due to the noncommutativity as well as the curvature of this space, the renormalization of the two-point function differs from the commutative case. In particular, we show that the theory in the limit of small curvature and noncommutativity is described by a model similar to the Grosse-Wulkenhaar one. Moreover, very much akin to what happens in the Grosse-Wulkenhaar model, our computation demonstrates that there exists a fixed point in the renormalization group flow of the harmonic and mass terms.
