description: We present a method for using standard techniques from satisfiability checking to automatically verify and discover theorems in an area of economic theory known as ranking sets of objects. The key question in this area, which has important applications in social choice theory and decision making under uncertainty, is how to extend an agents preferences over a number of objects to a preference relation over nonempty sets of such objects. Certain combinations of seemingly natural principles for this kind of preference extension can result in logical inconsistencies, which has led to a number of important impossibility theorems. We first prove a general result that shows that for a wide range of such principles, characterised by their syntactic form when expressed in a many-sorted first-order logic, any impossibility exhibited at a fixed (small) domain size will necessarily extend to the general case. We then show how to formulate candidates for impossibility theorems at a fixed domain size in propositional logic, which in turn enables us to automatically search for (general) impossibility theorems using a SAT solver. When applied to a space of 20 principles for preference extension familiar from the literature, this method yields a total of 84 impossibility theorems, including both known and nontrivial new results.

description: In this note, we present explicit conditions for symmetric gradient type Dirichlet forms to be recurrent. This type of Dirichlet form is typically strongly local and hence associated to a diffusion. We consider the one dimensional case and the multidimensional case, as well as the case with reflecting boundary conditions. Our main achievement is that the explicit results are obtained under quite weak assumptions on the closability, hence regularity of the underlying coefficients. Especially in dimension one, where a Hamza type condition is assumed, the construction of the sequence of functions $(u_n)_{n\in \N}$ in the Dirichlet space that determine recurrence works for quite general Dirichlet forms but is still explicit.

description: In action domains where agents may have erroneous beliefs, reasoning about the effects of actions involves reasoning about belief change. In this paper, we use a transition system approach to reason about the evolution of an agents beliefs as actions are executed. Some actions cause an agent to perform belief revision while others cause an agent to perform belief update, but the interaction between revision and update can be non-elementary. We present a set of rationality properties describing the interaction between revision and update, and we introduce a new class of belief change operators for reasoning about alternating sequences of revisions and updates. Our belief change operators can be characterized in terms of a natural shifting operation on total pre-orderings over interpretations. We compare our approach with related work on iterated belief change due to action, and we conclude with some directions for future research.

description: In this paper we solve numerically a degenerate parabolic equation with dynamical boundary conditions of zero-coupon bond pricing. First, we discuss some properties of the differential equation. Then, starting from the divergent form of the equation we implement the finite-volume method of S. Wang [16] to discretize the differential problem. We show that the system matrix of the discretization scheme is a M-matrix, so that the discretization is monotone. This provides the non-negativity of the price with respect to time if the initial distribution is nonnegative. Numerical experiments demonstrate the efficiency of our difference scheme near the ends of the interval where the degeneration occurs.

description: We present non-linear uplift ansaetze for all the bosonic degrees of freedom and dual fields in the 7-sphere reduction of D=11 supergravity to maximal SO(8) gauged supergravity and test them for the SO$(7)^{\pm}$ invariant solutions. In particular, we complete the known ansaetze for the internal components of the metric and 4-form flux by constructing a non-linear ansatz for the internal components of the dual 7-form flux. Furthermore, we provide ansaetze for the complete set of 56 vector fields, which are given by more general structures than those available from standard Kaluza-Klein theory. The novel features encountered here have no conventional geometric interpretation and provide a new perspective on Kaluza-Klein theory. We study the recently found set of generalised vielbein postulates and, for the 7-sphere compactification, we show that they reduce to the E7(7) Cartan equation of maximal SO(8) gauged supergravity in four dimensions. The significance of this framework for a higher-dimensional understanding of the embedding tensor and other gauged maximal supergravities is briefly discussed.

description: We investigate the angular dependence of the magnetoresistance of thin (< 1 nm), metallic SrTiO3 quantum wells epitaxially embedded in insulating, ferrimagnetic GdTiO3 and insulating, antiferromagnetic SmTiO3, respectively. The SrTiO3 quantum wells contain a high density of mobile electrons (~7x10^14 cm^-2). We show that the longitudinal and transverse magnetoresistance in the structures with GdTiO3 are consistent with anisotropic magnetoresistance, and thus indicative of induced ferromagnetism in the SrTiO3, rather than a nonequilibrium proximity effect. Comparison with the structures with antiferromagnetic SmTiO3 shows that the properties of thin SrTiO3 quantum wells can be tuned to obtain magnetic states that do not exist in the bulk material.

description: We offer a new understanding of some aspects of practical SAT-solvers that are based on DPLL with unit-clause propagation, clause-learning, and restarts. We do so by analyzing a concrete algorithm which we claim is faithful to what practical solvers do. In particular, before making any new decision or restart, the solver repeatedly applies the unit-resolution rule until saturation, and leaves no component to the mercy of non-determinism except for some internal randomness. We prove the perhaps surprising fact that, although the solver is not explicitly designed for it, with high probability it ends up behaving as width-k resolution after no more than O(n^2k+2) conflicts and restarts, where n is the number of variables. In other words, width-k resolution can be thought of as O(n^2k+2) restarts of the unit-resolution rule with learning.

description: Weighted voting is a classic model of cooperation among agents in decision-making domains. In such games, each player has a weight, and a coalition of players wins the game if its total weight meets or exceeds a given quota. A players power in such games is usually not directly proportional to his weight, and is measured by a power index, the most prominent among which are the Shapley-Shubik index and the Banzhaf index.In this paper, we investigate by how much a player can change his power, as measured by the Shapley-Shubik index or the Banzhaf index, by means of a false-name manipulation, i.e., splitting his weight among two or more identities. For both indices, we provide upper and lower bounds on the effect of weight-splitting. We then show that checking whether a beneficial split exists is NP-hard, and discuss efficient algorithms for restricted cases of this problem, as well as randomized algorithms for the general case. We also provide an experimental evaluation of these algorithms. Finally, we examine related forms of manipulative behavior, such as annexation, where a player subsumes other players, or merging, where several players unite into one. We characterize the computational complexity of such manipulations and provide limits on their effects. For the Banzhaf index, we describe a new paradox, which we term the Annexation Non-monotonicity Paradox.

description: Essential fatty acid plays a major role in the health of canines. They are required for the functioning of smooth muscles, internal organs, brain, and skin. The deficiency of fatty acids inn the body will be exhibited in different clinical signs. Often this will be overlooked and the clinician will follow a conventional approach in diagnosis and therapy. If the condition is improving then further tests will be done and a clinical trial of drugs will be followed. But considering the importance of nutritional medicine, it is imperative to look into the possibilities of nutrition driven disorders inn animals. In this article we are emphasizing the importance of proper nutrition especially need of the fatty acids in the diet of canines for their proper health with a scientific detailing of Omega-3, Omega-6.

description: Many bacteria in nature exist in multicellular communities termed biofilms, where cells are embedded in an extracellular matrix that provides rigidity to the biofilm and protects cells from chemical and mechanical stresses. In the Gram-positive model bacterium Bacillus subtilis, TasA is the major protein component of the biofilm matrix, where it has been reported to form functional amyloid fibres contributing to biofilm structure and stability. Here, we present electron cryomicroscopy structures of TasA fibres, which show that, rather than forming amyloid fibrils, TasA monomers assemble into fibres through donor-strand exchange, with each subunit donating a β-strand to complete the fold of the next subunit along the fibre. Combining electron cryotomography, atomic force microscopy, and mutational studies, we show how TasA fibres congregate in three dimensions to form abundant fibre bundles that are essential for B. subtilis biofilm formation. Our study explains the previously observed biochemical properties of TasA and shows how a bacterial extracellular globular protein can assemble from monomers into β-sheet-rich fibres, and how such fibres assemble into bundles in biofilms.

description: The Internet has been ascribed a prominent role in collective action, particularly with widespread use of social media. But most mobilisations fail. We investigate the characteristics of those few mobilisations that succeed and hypothesise that the presence of 'starters' with low thresholds for joining will determine whether a mobilisation achieves success, as suggested by threshold models. We use experimental data from public good games to identify personality types associated with willingness to start in collective action. We find a significant association between both extraversion and internal locus of control, and willingness to start, while agreeableness is associated with a tendency to follow. Rounds without at least a minimum level of extraversion among the participants are unlikely to be funded, providing some support for the hypothesis.

description: Chronic kidney disease (CKD) and haemodialysis (HD) are associated with an increased risk of hepatitis B infection due to exposure to the virus during haemodialysis, in conjunction with impaired seroconversion to hepatitis B vaccination (HBV). Studies examining augmented vaccine schedules to enhance seroconversion have so far been inconclusive. Furthermore, the cellular defects responsible for impaired vaccine immunity observed in CKD and HD have not yet been identified. This project studied serological and cellular responses to HBV in CKD and HD to identify defects in vaccine-induced cellular responses that could account for impaired seroconversion and clarify the effects of an augmented vaccine dose schedule. These results were compared with responses to seasonal influenza vaccination. There was a clear benefit in rates and magnitude of seroconversion after an augmented 40mcg HBV dose schedule in CKD. This permitted comparison of responders and non-responders. Serological non-responders with CKD exhibited a reduction in CXCR3+CCR6- CXCR5+ memory T cells at baseline. Seasonal influenza vaccine elicited a plasmablast (PB) response in both healthy controls and CKD, but HBV elicited a poor plasmablast response in both groups. Both vaccinations induced activation of the CXCR3+CCR6- subset of circulating T follicular helper cells (cTFH) in healthy controls, and but this response was impaired in CKD after HBV, even with the augmented 40mcg HBV dose schedule, and appears not to be reversed by haemodialysis. Despite this, some patients receiving haemodialysis generate detectable post-vaccination HBsAb, and this correlates with activation within the CXCR3+CCR6- cTFH compartment. We concluded that cellular responses to seasonal influenza vaccine are preserved in CKD and haemodialysis. However, CKD confers a specific defect in cTFH activation that contributes to the impaired seroconversion to HBV, and this defect persists despite renal replacement therapy with haemodialysis.

description: When faced with the problem of learning a model of a high-dimensional environment, a common approach is to limit the model to make only a restricted set of predictions, thereby simplifying the learning problem. These partial models may be directly useful for making decisions or may be combined together to form a more complete, structured model. However, in partially observable (non-Markov) environments, standard model-learning methods learn generative models, i.e. models that provide a probability distribution over all possible futures (such as POMDPs). It is not straightforward to restrict such models to make only certain predictions, and doing so does not always simplify the learning problem. In this paper we present prediction profile models: non-generative partial models for partially observable systems that make only a given set of predictions, and are therefore far simpler than generative models in some cases. We formalize the problem of learning a prediction profile model as a transformation of the original model-learning problem, and show empirically that one can learn prediction profile models that make a small set of important predictions even in systems that are too complex for standard generative models.

Bone by bone: phylogeny of the ape cranium
Creators: name: Pearson, Alannah Kirsty
Publisher: name: The Australian National University
Year: 2015

description: There is perhaps no topic more richly investigated in physical anthropology than the phylogeny of our closest relatives: the hominoids. Studies have ranged from examining how qualitative and metric traits differ, variation in molecular structure and how cranial modules contribute to phylogenetic history. Despite this, there has been no single study comparing individual cranial bones and their effects on phylogeny. This study explores how allometric and non-allometric shape impact on phylogeny and whether phylogenetic methods and geometric morphometrics are compatible by comparing morphological phylogenies to the accepted molecular phylogeny. I conducted a suite of multivariate and geometric morphometric analyses to reconstruct the phylogenies of great apes (N=177) and small apes (N=57) from virtually generated three-dimensional cranial models. From these models, I analysed phylogenetic signal and the allometric and non-allometric shape of seven cranial bones. Results were surprising: almost all bones in the cranium provide strong phylogenetic signal support but this did not translate into the accepted phylogenies being reconstructed. The phylogenies express morphology dominated by robust superstructures with more gracile morphology forming a separate clade. This strongly suggests a dominance of morphologies dependent on robusticity. Researchers must be careful in interpreting fossil hominin taxonomy using geometric morphometrics for, as this study has shown, morphologies dependent on robusticity will cluster in phylogenetic trees but may not be congruent with the molecular phylogeny. Due to the nature of preservation, fossils will likely never have a complete molecular phylogeny and this study provides a warning for use of methods which are common-place now but carry unexpected results.

description: Quantum Information Processing, from cryptography to computation, based upon linear quantum optical circuit elements relies heavily on the ability offered by the Hong-Ou-Mandel (HOM) Effect to route photons from separate input modes into one of two common output modes. Specifically, the HOM Effect accomplishes the path entanglement of two photons at a time such that no coincidences are observed in the output modes of a system exhibiting the effect. In this paper, we prove in principle that a significant increase in the robustness of the HOM Effect can be accomplished in a scalable, readily manufactured nanophotonic system comprised of two waveguides coupled, on chip, to a ring resonator. We show that by operating such a device properly, one can conditionally bunch coincident input photons in a way that is far more robust and controllable than possible with an ordinary balanced beam splitter.

description: BACKGROUND: Maternal prenatal infections have been linked to children's neurodevelopment and cognitive outcomes. It remains unclear, however, whether infections occurring during specific vulnerable gestational periods can affect children's cognitive outcomes. The study aimed to examine maternal infections in each trimester of pregnancy and associations with children's developmental and intelligence quotients. The ALSPAC birth cohort was used to investigate associations between maternal infections in pregnancy and child cognitive outcomes. METHODS: Infection data from mothers and cognition data from children were included with the final study sample size comprising 7,410 mother-child participants. Regression analysis was used to examine links between maternal infections occurring at each trimester of pregnancy and children's cognition at 18 months, 4 years, and 8 years. RESULTS: Infections in the third trimester were significantly associated with decreased verbal IQ at age 4 (p < .05, adjusted R2 = 0.004); decreased verbal IQ (p < .01, adjusted R2 = 0.001), performance IQ (p < .01, adjusted R2 = 0.0008), and total IQ at age 8 (p < .01, adjusted R2 = 0.001). CONCLUSION: Results suggest that maternal infections in the third trimester could have a latent effect on cognitive development, only emerging when cognitive load increases over time, though magnitude of effect appears to be small. Performance IQ may be more vulnerable to trimester-specific exposure to maternal infection as compared to verbal IQ. Future research could include examining potential mediating mechanisms on childhood cognition, such as possible moderating effects of early childhood environmental factors, and if effects persist in future cognitive outcomes.

The impact of primary care delays on survival of colorectal cancer patients
Creators: name: Arhi, Chanpreet
Publisher: name: Imperial College London
Year: 2019

description: Survival for colorectal cancer patients in the UK lags behind other Western European countries. This thesis aims to explore the impact of delays in referral and missed opportunities in primary care on survival for colorectal cancer patients. For this purpose patients were identified from the Clinical Practice Research Datalink (CPRD), a national electronic primary care medical record database, with a diagnosis of colorectal cancer in the National Cancer Registry. The initial studies validate the use of CPRD to fulfil the aims of this thesis, by confirming patients included are representative of the wider national cancer population. In the latter chapters the association of delays in referral with survival are investigated using a retrospective cohort design, while adjusting for patient demographics and co-morbidities. Delays are defined as a referral after three months or after three or more consultations. In addition, missed opportunity for non-emergency diagnosis were identified for emergency patients with a previous consultation in primary care. Survival between the urgent and non-urgent referral pathways are also explored. This thesis demonstrates delays were associated with a worse survival and later stage for patients presenting with red-flag symptoms (as defined by NICE) but not non-specific symptoms. Presenting with non-specific symptoms was associated with a worse stage and emergency diagnosis independently. There was no difference in survival or stage for patients referred by the non-urgent pathway compared with the two-wait-week pathway. Identification of cancer patients in primary care is a difficult task. These findings suggest patients presenting with red-flag symptoms, and in particular rectal bleeding are presenting at an earlier stage providing an opportunity for a better prognosis if the referral is prompt. Alternative methods to differentiate cancer from benign patients need to be considered, as relying only on symptoms is insufficient.

description: Comprehensive assessment of the virtual water trade of Germany with the world is performed and the national water footprint through the trade of crop and livestock products from 1991 to 2016 is assessed. Virtual water flows based on 328 products with more than 200 countries indicate Germany as a net virtual water importer. Average virtual water import was 100.5 Bm3/y, virtual water export was 60.2 Bm3/y and net virtual water import was 40.3 Bm3/y. Trade patterns of virtual water transfer differ for the various commodity types. Trade between Germany and the world implies a global water loss of 5.9 Bm3/y. This study portrays that trade between countries is not only related to the economics but interlinked with the agricultural water use and management practices of the respective nations. Sustainable management of the resources will require a collective consideration of the agricultural, water and economic sectors while developing strategies.
Non-Pharmacological Effects of Ketamine for Depressed Patients in the Perioperative Period

description: Major Depressive Disorder (MDD) is a severe mental illness, ranking in the top contributors to global disease burden. Moreover, during a perioperative period, a diagnosis of MDD increases risk of negative surgical outcomes. While several trials have explored the hallucinogen ketamine for its antidepressant effects, there is limited research into its efficacy when administered during general anesthesia. Our subsequent randomized controlled trial indicates that postoperative mood is influenced not only by ketamine infusion, but rather strongly by expectancy bias, quality of recovery, and other non-pharmacological effects. We employed a dataset of similar surgical patients not enrolled in any trials to investigate expectancy and examine whether current measurement tools are appropriately quantifying mood in this setting. We suggest that, in the perioperative period of a clinical trial, expectancy bias might drive the positive effects of ketamine, clinicians and patients report symptoms of depression differently, and patient-rated data on mood is unreliable.

description: The Beam Driven Plasma Neutralizer (BDPN) has been proposed as a more efficient alternative to the gas neutralizer for negative-ion based Neutral Beam Injection (NNBI). In this paper we model the performance of an entire NNBI beamline with a BDPN. We simultaneously consider all the relevant physics and engineering aspects, the most important being the plasma density and degree of ionization inside the BDPN as a function of its geometry and feed gas flow, the geometrical transmission of the beamline, the dependence of the neutral gas distribution in the beamline on the geometry of the beamline components and gas flows, and the species evolution of the extracted D$^-$ beam through this neutral and charged particle distribution. Furthermore, we calculate the heat loads expected on the BDPN parts and on the NBI components located downstream of it and study the effect of the magnetic cusp field across the BDPN entrance on beamline transmission. While our results constitute an optimization only under the applied boundary conditions, we find that the beamline with a BDPN increases the system's wall plug efficiency by about 13% to 0.34 from the 0.30 estimated for a gas neutralizer.

description: Markovian processes have long been used to model stochastic environments. Reinforcement learning has emerged as a framework to solve sequential planning and decision-making problems in such environments. In recent years, attempts were made to apply methods from reinforcement learning to construct decision support systems for action selection in Markovian environments. Although conventional methods in reinforcement learning have proved to be useful in problems concerning sequential decision-making, they cannot be applied in their current form to decision support systems, such as those in medical domains, as they suggest policies that are often highly prescriptive and leave little room for the users input. Without the ability to provide flexible guidelines, it is unlikely that these methods can gain ground with users of such systems. This paper introduces the new concept of non-deterministic policies to allow more flexibility in the users decision-making process, while constraining decisions to remain near optimal solutions. We provide two algorithms to compute non-deterministic policies in discrete domains. We study the output and running time of these method on a set of synthetic and real-world problems. In an experiment with human subjects, we show that humans assisted by hints based on non-deterministic policies outperform both human-only and computer-only agents in a web navigation task.

description: We present Maxwellian-averaged effective collision strengths for the electron-impact excitation of S III over a wide range of electron temperatures of astrophysical importance, log T(K) = 3.0-6.0. The calculation incorporates 53 fine-structure levels arising from the six lowest configurations, giving rise to 1378 individual lines, and is undertaken using the recently developed RMATRX II plus FINE95 suite of codes. A detailed comparison is made with a previous R-matrix calculation and significant differences are found for some transitions. The atomic data are subsequently incorporated into the modeling code CLOUDY to generate line intensities for a range of plasma parameters, with emphasis on allowed UV and EUV emission lines detected from the Io plasma torus. Electron density-sensitive line ratios are calculated with the present atomic data and compared with those from CHIANTI v7.1, as well as with Io plasma torus spectra obtained by FUSE and EUVE. The present line intensities are found to agree well with the observational results and provide a noticeable improvement upon the values predicted by CHIANTI.

description: The modern software engineering practices of Agile and DevSecOps have revolutionized the practice of software engineering. These strategies have provided a foundation for producing working software products faster and more reliably than ever before. However, we found that most literature about Agile and DevSecOps focuses on the product and ignores the business mission and capability-delivery aspects of every software product under development. This gap is problematic because not every team in a software-oriented organization is directly involved with the development of the product and, in fact, the business mission and capability delivery aspects of DevSecOps are critical to the successful delivery of the product.

description: Staff rostering is a crucial task in inbound call centers, as personnel costs usually account for the largest share of operating costs. Uncertainty of capacity, such as the presence of agents is often disregarded during rostering. This paper addresses the problem of uncertainty by using predictive analytics to predict agent absences and thus increase roster robustness. Operational data from four years of a call center serves as a basis for our use case. Predictors include characteristics of the service agents such as attendance history and regular working hours as well as other factors such as the weekday. Of the prediction algorithms tested, decision trees outperform other predictive modeling approaches. Evaluation based on an expected value framework shows that the predictive analytics approach performs best compared to the planned, unchanged roster and a general staff surcharge of 10%.
title: Measuring the environmental impact of cultural and creative sector authentic assessment (CHEP festival)

description: Sustainability concerns are increasingly important priorities for cultural and creative sector students. However, the implications of creative practice design and resourcing decisions require further exploration and reflection.
Our CHEP Development Fund project connects higher education's learning and teaching focus on sustainability with comparable cultural and creative sector initiatives to examine how students can measure and reflect on the environmental impact of authentic assessment activities.
This workshop will be structured intro three parts: (1) context - exploring the meeting points of education for sustainable development (ESD), authentic assessment and environmental reporting in the cultural and creative industries (2) demonstration - introducing a bespoke toolkit developed during the project with Fashion and Textiles staff and students (3) extension - discussing ideas on how to develop the toolkit and support its use across the University.

description: We construct a molecule of fractional vortices with fractional topological lump charges as a baby Skyrmion with the unit topological lump charge in the anti-ferromagnetic (or XY) baby Skyrme model, that is, an O(3) sigma model with a four derivative term and an anti-ferromagnetic or XY-type potential term quadratic in fields. We further construct configurations with topological lump charges Q <= 7 and find that bound states of vortex molecules constitute regular polygons with 2Q vertices as vortices, where the rotational symmetry SO(2) in real space is spontaneously broken into a discrete subgroup Z_Q. We also find metastable and arrayed bound states of fractional vortices for Q=5,6. On the other hand, we find for Q=7 that the regular polygon is metastable and the arrayed bound state is stable. We calculate binding energies of all configurations.

description: Effective and efficient control over the subsidy payments, associated with the relevant agrarian policies and obligations imposed by the Common Agricultural Policy (CAP) requires systematic and timely monitoring of the agricultural landscape. In this regard, the introduction of the Sentinel-1 and Sentinel-2 missions, offering open access to satellite data of unprecedented spectral, spatial and temporal characteristics, enable the development of reliable solutions for large-scale operational agriculture monitoring systems.

To this end, the RECAP project (Horizon 2020) developed an improved remote monitoring of CAP Cross Compliance and Greening obligations. Within this context, the National Observatory of Athens (NOA) has developed a Remote Sensing platform that implements on-demand, robust, transferable and efficient fully automated processing chains, towards evidence-based decision making in the CAP.

Accurate crop classification serves as the main pillar of the overall system. The methodology uses a parcel-based satellite image (Sentinel-2) time-series approach, under a supervised classification scheme. Produced crop type maps are straightforwardly utilized for conformity checks on CAP’s crop diversification requirements. An automated water pollution risk estimation method was also implemented to enable the identification of parcels prone to polluted water/soil runoff, accordant to the Statutory Management Requirements (SMR) of the CAP. Finally, Burn Scar Mapping algorithms have also been developed to directly monitor and control the stubble burning restrictions imposed by the policy.

This agriculture monitoring scheme has been successfully applied in 5 diverse local scale pilot scenarios, within the context of the RECAP project. NOA seeks to extend and scale up the application of the scheme, by incorporating big data technologies and other mature ICT solutions for the monitoring of food security at national and international scales, this time under the scope of the H2020 project EOPEN.
Orbital Magnetism Induced by Heat Currents in Mott insulators

description: We derive the effective heat current density operator for the strong-coupling regime of Mott insulators. Similarly to the case of the electric current density, the leading contribution to this effective operator is proportional to the local scalar spin chirality $\hatχ_{jkl}= \mathbf{S}_l\cdot\left(\mathbf{S}_j\times \mathbf{S}_k\right)$. This common form of the effective heat and electric current density operators leads to a novel cross response in Mott insulators. A heat current induces a distribution of orbital magnetic moments in systems containing loops of an odd number of hopping terms. The relative orientation of the orbital moments depends on the particular lattice of magnetic ions. This subtle effect arises from the symmetries that the heat and electric currents have in common.
