description: Background: Rheumatoid Arthritis (RA) is a chronic inflammatory autoimmune disease with an estimated global prevalence of 0.46%. Chronic low-grade inflammation is central in the pathogenesis and progression of RA. With no cure, the treatment goals of RA are to control symptoms, prevent joint damage and improve quality of life and ability to function. Accumulating evidence suggests that diet may play an important role in RA management and even remission. However, to date, there is a lack of evidence supporting a preferred diet. The Mediterranean diet (MedDiet), recognised for its anti-inflammatory properties, is one the most researched diets for prevention and management of chronic diseases. However, very few trials have assessed a MedDiet with RA specific outcomes and in non-Mediterranean countries. Improving the evidence base for diet in people with RA could serve to inform the development of dietary guidelines for this patient population and ultimately improve patient outcomes. Aims: The primary aim of this doctorate is to investigate the impact of a MedDiet in the management of RA. Methods: To achieve the aims, the research strategy undertaken involves; (i) A systematic review on the effectiveness of dietary interventions in RA (Chapter 2); (ii) A RCT examining the effects of a MedDiet compared to the Irish Healthy Eating Guidelines (HEG) on physical function and quality of life in adults with RA in Ireland (MEDRA, Chapter 3); (iii) A qualitative exploration of participants’ experiences following the 12-week telehealth-delivered dietary intervention (Chapter 4); (iv) A cross-sectional study investigating the self-perceived levels of adherence and the barriers, and enablers toward adherence to a MedDiet in the general Irish population (Chapter 5). Results: Key findings from this programme of research: • The systematic review of dietary interventions found that diets with an anti-inflammatory basis such as the MedDiet may be an effective strategy in the management of RA. An anti-inflammatory diet supplemented with omega-3 polyunsaturated fatty acids may provide additional benefits. • The MEDRA RCT found that both a MedDiet and adhering to the Irish HEG significantly improved physical function and quality of life in adults with RA. Improving dietary quality irrespective of dietary prescription is beneficial in an RA population. • The telehealth component of the intervention was positively received by adults with RA. The MedDiet was well accepted by an Irish population with RA. • The observational study indicated low adherence to the MedDiet in a healthy population residing in Ireland. Conclusion: Diet must be considered as part of the overall management of people with RA. Adherence to a MedDiet is feasible in an Irish population. Larger observational and interventional studies are required to confirm and expand upon these findings.

description: Let S be a commutative semiring. M. Droste and P. Gastin have introduced in 2005 weighted monadic second order logic WMSOL with weights in S. They use a syntactic fragment RMSOL of WMSOL to characterize word functions (power series) recognizable by weighted automata, where the semantics of quantifiers is used both as arithmetical operations and, in the boolean case, as quantification. Already in 2001, B. Courcelle, J.Makowsky and U. Rotics have introduced a formalism for graph parameters definable in Monadic Second order Logic, here called MSOLEVAL with values in a ring R. Their framework can be easily adapted to semirings S. This formalism clearly separates the logical part from the arithmetical part and also applies to word functions. In this paper we give two proofs that RMSOL and MSOLEVAL with values in S have the same expressive power over words. One proof shows directly that MSOLEVAL captures the functions recognizable by weighted automata. The other proof shows how to translate the formalisms from one into the other.

description: Orthodontic treatment even though managed and properly controlled , on some remote occasion may lead to presence of unwanted movement. Anterior open bite is one such example of an iatrogenic outcome. This article describes the management of an iatrogenic anterior open bite case that occurred in active orthodontic treatment in the early stage of leveling and aligning. A few modalities had been employed to manage the open bite through some artistic bends followed by the use of modified low transpalatal arch with extended looped arms with loops as well as orthodontic mini implants for distalisation and some intrusion mechanics. This case report is aimed to share authors’ anecdotal experience on overcoming the open bite.

description: In this article we provide representations for the one-loop three point functions in 4 and 6 dimensions in the general case with complex masses. The latter are part of the GOLEM library used for the computation of one-loop multileg amplitudes. These representations are one-dimensional integrals designed to be free of instabilites induced by inverse powers of Gram determinants, therefore suitable for stable numerical implementations.

description: We conduct studies on Levin's taxonomy of periodic orbits for neutral test particles around a Reissner-Nordström naked singularity. It was known that naked singularities could harbor two distinct regions of time-like bound orbits and thus we expect periodic orbits to appear in both regions. It is possible for a pair of periodic orbits from both regions to possess the exact same angular momentum $L$ and energy $E$ values. We chart the sets of periodic orbits in $(L,E)$-parameter space and highlight the general distribution pattern of these sets for three possible scenarios. Regions within $(L,E)$-space can be partitioned into multiple domains $\mathcal{D}_k$ based on the roots configuration of the quartic polynomial $P(u)$ where $u$ is the inverse radial coordinate. Consequently, each domain and interestingly enough, portions of certain periodic orbits sets that lie in different $\mathcal{D}_k$ require different analytical solutions to plot the resulting orbit. Furthermore, we uncover physical properties of some hypothetical circular orbits residing in the inner region from analysing the $(L,E)$-space.

description: Theories with a curved momentum space, which became recently of interest in the quantum-gravity literature, can in general violate many apparently robust aspects of our current description of the laws of physics, including relativistic invariance, locality, causality and global momentum conservation. We here explore some aspects of the particularly severe pathologies arising in generic theories with curved momentum space for what concerns causality and momentum conservation. However, we also report results suggesting that when momentum space is maximally symmetric, and the theory is formulated (DSR-)relativistically, with the associated relativity of spacetime locality, momentum is globally conserved and there is no violation of causality.

title: Extension of a Cross-Shore Beach Profile Model for Coarse Materials and Steep Slopes
Creators: name: Hayashi, Kentaro
Publisher: name: Old Dominion University Libraries
Year: 2004

description: In the present SBEACH model, the effective grain size can range from 0.13 to 1.0 mm. The grain size greatly influences three main processes of the model: fall velocity, sediment transport direction, and sediment transport rate. First, the theory of the fall velocity, which is called Hallermeier's formula in the SPM (1984), is replaced by the new theory in the CEM (2002). Second, the sediment transport direction is changed by two criteria. One was developed by Sunamura and Horikawa (1974). This theory includes the beach slope. The other was derived by Ahrens and Hands (2000). The effective grain size range is between 0.0625 and 30 mm. Finally, we assume that there is a similar trend between the cross-shore sediment transport rate and longshore sediment transport rate if the grain size becomes bigger. Based on this hypothesis, the cross-shore sediment transport rate coefficient is estimated for coarse sand by using two longshore sediment transport theories. Several modules in the original model were modified, based on the above theories. In this study, the modified model is called SBEACHX.

Model tests are performed under simple initial information to investigate the influence of the modules in SBEACHX if the grain size becomes large. The results are analyzed in terms of fall velocity, sediment transport direction, sediment transport rate, wave height, and wave period. It is found that as the grain size becomes larger, the sediment transport rate becomes smaller.

The efficiency of SBEACHX is investigated by comparing the results from SBEACHX with measurements from HR Wallingford, UK, and from the Public Works Research Institute (PWRI), the Ministry of Construction, Japan. However, SBEACH and SBEACHX could not reproduce beach profile change starting with the same initial beach profile and input wave conditions as the experiments. By analyzing the results, three reasons can be considered. The first reason is that the storm wave conditions in the laboratory experiments are not strong enough to move the sediment in SBEACH. The second reason is that there is a limitation of slope in the sediment transport model. The third reason is that the algorithm of the sediment transport for the swash zone in SBEACH is not appropriate for coarse materials and steep beaches. Also, the sediment transport direction theory in SBEACH cannot predict the correct direction from the Japanese experiment.

Finally, it is concluded that the modified model developed in this study cannot predict beach profile change with coarse material. For future work, more full-scale experiments with coarse materials and steep slopes under proper storm conditions for SBEACH are recommended to investigate the sediment transport model with considering coarse materials and steep slopes.

description: In this work we present an in-depth analysis of the user behaviors on different Social Sharing systems. We consider three popular platforms, Flickr, Delicious and StumbleUpon, and, by combining techniques from social network analysis with techniques from semantic analysis, we characterize the tagging behavior as well as the tendency to create friendship relationships of the users of these platforms. The aim of our investigation is to see if (and how) the features and goals of a given Social Sharing system reflect on the behavior of its users and, moreover, if there exists a correlation between the social and tagging behavior of the users. We report our findings in terms of the characteristics of user profiles according to three different dimensions: (i) intensity of user activities, (ii) tag-based characteristics of user profiles, and (iii) semantic characteristics of user profiles.

description: The use of 5G New Radio (NR) spectrum around 26 GHz is currently raising the quest on its compatibility with the well-established Earth Exploration-Satellite Service (EESS), which may be blinded by the spurious radiation emitted Above-the-Horizon (AtH) by Base Station (BS) antennas. Indeed, AtH grating lobes are often present during cell scanning due to the large inter-element spacing in BS array antennas for achieving higher gains with a reduced number of RF chains. In this letter, we propose an approach based on an electrically thin metasurface-based dome for the reduction of AtH grating lobes in 5G-NR BS antennas. The proposed scanning range shifting approach exploits the natural lower amplitude of the grating lobes when the antenna array scans in an angular region closer to the broadside direction. The grating lobe reduction is here demonstrated considering a 1x4 phased linear antenna array operating under dual-liner 45deg-slant polarization. A simple design procedure for designing the metasurface dome is reported, together with the antenna performances, evaluated through a proper set of numerical experiments. It is shown that the grating lobe radiation towards the satellite region is significantly reduced, whereas the overall insertion loss is moderate.

description: An incomplete albeit well preserved tooth from the Late Jurassic Tacuarembó Formation (Uruguay) shows a character combination only found in abelisaurid theropods, i.e. irregular enamel, hooked distal denticles, interdenticular sulci, lanceolate cross-sectional shape, and straight distal border. Its referral to Abelisauridae was tested via a phylogenetic analysis, with the Uruguayan taxon deeply nested within the clade. This is the first record of abelisaurids in Uruguay and one of the few Jurassic records of the group worldwide. Abelisaurids occur together with ceratosaurids and megalosaurines in the Tacuarembó Formation, revealing a rich Late Jurassic theropod assemblage.

description: Lattice QCD simulations are now reaching a precision where electromagnetic corrections from QED become important. In investigating the effects of SU(3) breaking due to quark mass differences within QCD, a group-theoretical analysis of the mass dependence greatly helped us organize our results. We now do the same with electromagnetic charge effects by extending the calculations to dynamical 1+1+1 flavor QCD + QED.

description: The Lohan Cura Formation (Albian) at the Cerro de los Leones locality (Neuquén Province, Patagonia, Argentina) yielded several fossil materials, especially sauropod specimens. Among these, Agustinia ligabuei includes postcranial elements of a single individual, with widely debated taxonomy and phylogeny. Here, we provide an extended osteological description and illustrations of the axial and appendicular elements of Agustinia, as well as a revised diagnosis. Moreover, the phylogenetic analysis including a new combination of morphological features recognises Agustinia as a basal Rebbachisauridae, closely related with other South American rebbachisaurids. Our results suggest a more diversified sauropod fauna in the Neuquén Basin, where different members of both neosauropod lineages (i.e. Macronaria and Diplodocoidea) survived in the same region during the Albian age. The reassessment of Agustinia as a basal rebbachisaurid improves our knowledge about the early stages of evolutionary history of Rebbachisauridae, adding new information on the morphological and taxonomic diversification of the clade during the Early Cretaceous of southwestern Gondwana.

description: We consider directed graphs where each edge is labeled with an integer weight and study the fundamental algorithmic question of computing the value of a cycle with minimum mean weight. Our contributions are twofold: (1) First we show that the algorithmic question is reducible in O(n^2) time to the problem of a logarithmic number of min-plus matrix multiplications of n-by-n matrices, where n is the number of vertices of the graph. (2) Second, when the weights are nonnegative, we present the first (1 + ε)-approximation algorithm for the problem and the running time of our algorithm is \tilde(O)(n^ωlog^3(nW/ε) / ε), where O(n^ω) is the time required for the classic n-by-n matrix multiplication and W is the maximum value of the weights.

description: The Daniels collection of fossil birds from the early Eocene London Clay of Walton-on-the-Naze (Essex, UK) contains multiple specimens of the Psittacopedidae and Zygodactylidae, which are here for the first time studied in detail. The Psittacopedidae include Parapsittacopes bergdahli, Psittacomimus eos, gen. et sp. nov., ?Psittacopes occidentalis, sp. nov., and at least one further unnamed species. The Zygodactylidae comprise Primozygodactylus cf. danielsi, Primoscens cf. minutus, Primoscens carolinae, sp. nov., as well as several unnamed species, which are represented by fragmentary remains. A very small zygodactylid-like species, which was previously identified as P. minutus, is described as Minutornis primoscenoides, gen. et sp. nov. A phylogenetic analysis showed the Zygodactylidae and Psittacopedidae to be stem group representatives of the Passeriformes (passerines), but the exact interrelationships of the fossil taxa are poorly resolved. In particular, no compelling character evidence supports a monophyletic Zygodactylidae, with distinctive features of these birds being likely to be plesiomorphic for Psittacopasseres or also found in crown group Passeriformes. In the majority rule consensus tree of our analysis, Minutornis is the sister taxon of a clade including the Zygodactylidae and Passeriformes, whereas the affinities of the Psittacopedidae were insufficiently resolvedhttp://zoobank.org/urn:lsid:zoobank.org:pub:81800349-5DE9-468B-81D7-6A5664526DF1.

description: We study the synergy between the long-baseline (LBL) experiments NO$ν$A and T2K and the atmospheric neutrino experiment ICAL@INO for obtaining the first hint of CP violation in the lepton sector. We also discuss how precisely the leptonic CP phase ($δ_{CP}$) can be measured by these experiments. The CP sensitivity is first described at the level of oscillation probabilities, discussing its dependence on the parameters -- $θ_{13}$, mass hierarchy and $θ_{23}$. In particular, we discuss how the precise knowledge or lack thereof of these parameters can affect the CP sensitivity of LBL experiments. We follow a staged approach and analyze the $δ_{CP}$ sensitivity that can be achieved at different points of time over the next 15 years from these LBL experiments alone and/or in conjunction with ICAL@INO. We find that the CP sensitivity of NO$ν$A/T2K is enhanced due to the synergies between the different channels and between the two experiments. On the other hand the lack of knowledge of hierarchy and octant makes the CP sensitivity poorer for some parameter ranges. Addition of ICAL data to T2K and NO$ν$A can exclude these spurious wrong-hierarchy and/or wrong-octant solutions and cause a significant increase in the range of $δ_{CP}$ values for which a hint of CP violation can be achieved. In fact in parameter regions unfavourable for NO$ν$A/T2K, we may get the first evidence of CP violation by adding the ICAL data to these. Similarly the precision with which $δ_{CP}$ can be measured also improves with inclusion of ICAL data.

description: Speculative optimisation relies on the estimation of the probabilities that certain properties of the control flow are fulfilled. Concrete or estimated branch probabilities can be used for searching and constructing advantageous speculative and bookkeeping transformations. We present a probabilistic extension of the classical equational approach to data-flow analysis that can be used to this purpose. More precisely, we show how the probabilistic information introduced in a control flow graph by branch prediction can be used to extract a system of linear equations from a program and present a method for calculating correct (numerical) solutions.

description: A microscopic kinetic theory is developed which allows to investigate non-Abelian SU(2) systems interacting with meanfields and spin-orbit coupling under magnetic fields in one, two, and three dimensions. The coupled kinetic equations for the scalar and spin components are presented and linearized with respect to an external electric field. The dynamical classical and quantum Hall effect are described in this way as well as the anomalous Hall effect where a new symmetric dynamical contribution to the conductivity is presented. The coupled density and spin response functions to an electric field are derived including arbitrary magnetic fields. The magnetic field induces a staircase structure at frequencies of the Landau levels. It is found that for linear Dresselhaus and Rashba spin-orbit coupling a dynamical out-of-plane spin response appears at these Landau level frequencies establishing terahertz resonances.

description: For a rotating galaxy, the inner circular-velocity gradient d_{R}V(0) provides a direct estimate of the central dynamical mass density, including gas, stars, and dark matter. We consider 60 low-mass galaxies with high-quality HI and/or stellar rotation curves (including starbursting dwarfs, irregulars, and spheroidals), and estimate d_{R}V(0) as V(R_d)/R_d, where R_d is the galaxy scale-length. For gas-rich dwarfs, we find that V(R_d)/R_d correlates with the central surface brightness mu(0), the mean atomic gas surface density Sigma_gas, and the star formation rate surface density Sigma_SFR. Starbursting galaxies, such as blue compact dwarfs (BCDs), generally have higher values of V(R_d)/R_d than dwarf irregulars, suggesting that the starburst is closely related to the inner shape of the potential well. There are, however, some "compact" irregulars with values of V(R_d)/R_d similar to BCDs. Unless a redistribution of mass takes place, BCDs must evolve into compact irregulars. Rotating spheroidals in the Virgo cluster follow the same correlation between V(R_d)/R_d and mu(0) as gas-rich dwarfs. They have values of V(R_d)/R_d comparable to those of BCDs and compact irregulars, pointing at evolutionary links between these types of dwarfs. Finally, we find that, similarly to spiral galaxies and massive starbursts, the star-formation activity in dwarfs can be parametrized as Sigma_SFR = epsilon*Sigma_gas/t_orb, where t_orb is the orbital time and epsilon = 0.02.

description: Crocodyliformes have a well-known worldwilde fossil record, revealing a high diversity of morphological traits, habits and being abundant in their paleofaunas. Such abundance in the fossil record is remarkable in the tetrapod fossil record in the continental sequences of Bauru Group (Brazil), in the Cretaceous of the South America. Here we describe and analyse three specimens from Bauru Group, assigned to a poorly understood crocodyliform clade: Itasuchidae. Their morphological similarity assigned them as Pepesuchus (from Turonian / Coniacian of Araçatuba Formation), Itasuchus cf. jesuinoi, and cf. Roxochampsa paulistanus (both last from Campanian to Early Maastrichtian of Presidente Prudente Formation). The phylogenetic and morphometric results corroborated the monophyly of the Itasuchidae with some variation in its content regard to prior and similar analyses (i.e. inclusion of Stolokrosuchus, Barreirosuchus and Antaeusuchus; exclusion of Caririsuchus), also pointing out to the South American itasuchid species as occupying a crocodyliform morphospace, which can imply distinct niche occupations. The Bauru Group undergoes a diversity peak of archosaurs in Upper Cretaceous, with a remarkable Crocodyliformes radiation, such as the Itasuchidae group, which probably have their most early-diverging lineages rising from Lower Cretaceous of Africa.

description: The self-oscillation of the magnetization in a spin torque oscillator (STO) with a perpendicularly magnetized free layer and an in-plane magnetized pinned layer in the absence of an applied magnetic field was studied by numerically solving the Landau-Lifshitz-Gilbert equation. It was pointed out that field-like torque was necessary to realize stable self-oscillation in this type of STO at zero field. The numerical simulation at finite temperature showed that the presence of the field-like torque led to a high power with a relatively high oscillation frequency.

description: We present the general purpose spectral energy distribution (SED) fitting tool SED Analysis Through Markov Chains (SATMC). Utilizing Monte Carlo Markov Chain (MCMC) algorithms, SATMC fits an observed SED to SED templates or models of the user's choice to infer intrinsic parameters, generate confidence levels and produce the posterior parameter distribution. Here we describe the key features of SATMC from the underlying MCMC engine to specific features for handling SED fitting. We detail several test cases of SATMC, comparing results obtained to traditional least-squares methods, which highlight its accuracy, robustness and wide range of possible applications. We also present a sample of submillimetre galaxies that have been fitted using the SED synthesis routine GRASIL as input. In general, these SMGs are shown to occupy a large volume of parameter space, particularly in regards to their star formation rates which range from ~30-3000 M_sun yr^-1 and stellar masses which range from ~10^10-10^12 M_sun. Taking advantage of the Bayesian formalism inherent to SATMC, we also show how the fitting results may change under different parametrizations (i.e., different initial mass functions) and through additional or improved photometry, the latter being crucial to the study of high-redshift galaxies.
