Maisin Christianity : an ethnography of the contemporary religion of a seaboard Melanesian people
Creators: name: Barker, John
Publisher: name: University of British Columbia
Year: 2010

description: This dissertation examines the ways in which a Papua New Guinean people, the Maisin of Collingwood Bay in Oro Province, have over the years responded to and appropriated a version of Christianity brought to them by Anglican missionaries. The Maisin treat Christianity not as a foreign imposition, but as an integral part of their total religious conceptions, activities and experiences. Almost a century of documented Maisin history reveals a consistency related to what is here called a "social ideology": a complex formed by idioms of asymmetry between senior and junior kin and allies, equivalence in exchanges between a range of social categories of persons, and complementarity between the sexes. Extensions of the social ideology to the developments of the post-contact society are explored in the contexts of a growing dependence on money and commodities, unequal access to education and jobs, large-scale out-migration, the material requirements of the local church, and church regulations concerning social behaviour. The social ideology is also extended to sorcerers, ancestral ghosts, bush spirits, and Christian divinities. The analysis shows that Maisin experience indigenous and Christian elements as realities that exist within a single religious field. Working from the premise that religion is an aspect of the people's total experience and not a separate cultural institution or sub-system, the thesis explores the modes by which the Maisin create and discover coherence between the various elements within the religious field. The most important points and occasions of religious coherence are those in which the moral precepts of the social ideology are joined with conceptions of spiritual entities towards the explanation and resolution of problems. Three "religious precipitates", as these moments of coherence are termed, are analysed: the village church, healing practices, and death rites. A major finding of this study is that Maisin articulate their assumptions about local sorcerers, ghosts, and spirits within idioms of conflict between kin and affinal groupings, but speak of God, Christ and the church as symbols of community solidarity. The village church is analysed as a point of convergence of the social ideology, economic aspirations, memories of past interactions with missionaries, and Christian teachings and forms. The primary religious importance of the church is as a condensed symbol of communitas that transcends the inherited divisions of the social order and the contradictions of present political and economic conditions.
title: Wetting of geometrical structures in the order of the capillary length
Creators: name: Gerlach, Felix
Publisher: name: UNSPECIFIED
Year: 2021

description: Wetting phenomena are often analyzed on the basis of single droplets or microscopic liquid flow phenomena. At industry scale such processes are rare and more often larger objects like wide rolls of material or whole car bodies are coated/wetted. At these scales macroscopic flow phenomena have a major impact on the wetting process. However, to simulate such processes it is necessary to reduce the complexity of the object surface in order to reduce the necessary computational resources. Therefore, the effects of geometrical features in the order of the capillary length on wetting have to be known in order to apply models instead of resolving them numerically. In this thesis the capillary rise in macroscopic right-angled corners is analyzed experimentally in order to capture the main physically relevant effects for large scale wetting. At the beginning of the thesis the experimental equipment and post-processing techniques utilized for the experiments are introduced. This experimental setup allows dipping experiments with objects of a size up to two orders of magnitude above the capillary length to be performed at speeds of 0.01 mm/s to 500 mm/s. These experiments are measured with an optical resolution of approximately 20 μm. After the introduction of the test rig, the new insights into capillary corner rise (also called rivulet rise) are presented. The interaction between concave and convex corners is analyzed by varying the inter-corner distance. This reveals the different length scales at which the concave corner alters the wetting at the convex corner and vice versa. Two models for the static shape of a rivulet are derived. One model combines different existing models from literature and the second model can be applied more generally and with fewer simplifications. The dynamics of rivulet rise are analyzed for three different situations. The change in rivulet rise emerging from concave and convex corners in close proximity to each other is analyzed and described empirically. Since industrial surfaces are produced with macroscopic fabrication methods, the corners are not mathematically sharp, but are microscopically round and the effect of this roundness on the rivulet rise is investigated and theoretically modeled. Since many industrial processes involve moving parts and forced wetting, the influence of forced immersion of a corner on the rivulet rise is also analyzed and described with two complementary models. The thesis concludes with first observations about the influence of roughness on wetting of flat walls. For this topic no models have been developed but different fabrication and measurement techniques have been tested and their characteristics are reported.

description: We consider the problem of determining a pair of functions $(u,f)$ satisfying the heat equation $u_t -Δu =φ(t)f (x,y)$, where $(x,y)\in Ω=(0,1)\times (0,1)$ and the function $φ$ is given. The problem is ill-posed. Under a slight condition on $φ$, we show that the solution is determined uniquely from some boundary data and the initial temperature. Using the interpolation method and the truncated Fourier series, we construct a regularized solution of the source term $f$ from non-smooth data. The error estimate and numerical experiments are given.

description: Using the two-body interactions obtained from a chiral constituent quark model we study all $ΛNN$ and $ΣNN$ states with I=0,1,2 and J=1/2,3/2 at threshold, taking into account all three-body configurations with S and D wave components. We constrain further the limits for the $ΛN$ spin-triplet scattering length a_{1/2,1}. Using the hypertriton binding energy we find a narrow interval for the possible values of the $ΛN$ spin-singlet scattering length a_{1/2,0}. We found that the $ΣNN$ system has a quasibound state in the (I,J) = (1,1/2) channel very near threshold with a width of about 2.1 MeV.

description: We present periodic Density Functional Theory calculations of the electronic properties of molecular junctions formed by amine-, and thiol-terminated alkane chains attached to two metal (Au, Ag) electrodes. Based on extensive analysis that includes molecular monolayers of varying densities, we establish a relationship between the alignment of the molecular energy levels and the interface dipoles, which shows that the band alignment (BA) in the limit of long, isolated chains is independent of the link group and can be computed from a reference system of non interacting molecule + metal electrodes. The main difference between the amine and thiol linkers is the effective dipole moment at the contact. This is very large, about 4.5 D, for amine linkers, leading to a strong dependence of the BA on the monolayer density and a slow convergence to the isolated molecule limit. Instead, this convergence is fast for S anchors due to the very small, ~ 0.2 D, effective dipoles at the contacts.

Relevance of Abelian Symmetry and Stochasticity in Directed Sandpiles

description: We provide a comprehensive view on the role of Abelian symmetry and stochasticity in the universality class of directed sandpile models, in context of the underlying spatial correlations of metastable patterns and scars. It is argued that the relevance of Abelian symmetry may depend on whether the dynamic rule is stochastic or deterministic, by means of the interaction of metastable patterns and avalanche flow. Based on the new scaling relations, we conjecture critical exponents for avalanche, which is confirmed reasonably well in large-scale numerical simulations.

Mapping the Meditative Path: The Effects of Conceptual Knowledge of Meditative Frameworks on Meditators’ Experiences in Long-Term Insight Practice

description: This paper addresses an increasingly contested topic in the contemporary Western vipassanā meditation movement: The dissemination of Buddhist frameworks like the “stages of insight,” the “ñāṇas” first seen in the 5th century Visudhimagga text, within cultures of mindfulness. The principal question is two-fold: 1) Would sharing such Buddhist frameworks protect potential Western meditators from possible (and underreported) harms of intensive practice? And 2) Does in-depth knowledge of such Buddhist frameworks help, hinder, or otherwise affect perceived progress for experienced meditators? While a growing body of literature has begun reifying the harms mentioned in the first question, the second question has gone unanswered academically despite being answered anecdotally within spiritual communities. Having struggled immensely myself to reconcile conceptual Buddhist knowledge with my own meditation practice, I hypothesize that knowledge of ñāṇas hinders meditative progress, and conduct in-depth, semi-structured interviews of experienced meditators to test this hypothesis. Through this interview-based field work, I construct an intersubjective account of the relationship between cerebral knowledge about meditation – a practice of non-cerebral engagement with one’s direct experience of reality – and meditation itself. Through the research interviews, the hypothesis that conceptualization of the meditative path through ñāṇas hinders vipassanā practice is confirmed, although benefits of meditative frameworks like the “stages of insight” also emerge. A number of themes related to the limitations of concepts emerge as well, fashioning contemporary American insight meditation into a lens through which I deconstruct the general truth of conceptualization philosophically. Pragmatically for meditators, on the other hand, I propose a new map of the meditative path that retains the relevant accuracy of the “stages of insight,” yet lets go of the conceptual trappings they present to Western practitioners.

description: The CHIME/FRB experiment has detected thousands of Fast Radio Bursts (FRBs) due to its sensitivity and wide field of view; however, its low angular resolution prevents it from localizing events to their host galaxies. Very Long Baseline Interferometry (VLBI), triggered by FRB detections from CHIME/FRB will solve the challenge of localization for non-repeating events. Using a refurbished 10-m radio dish at the Algonquin Radio Observatory located in Ontario Canada, we developed a testbed for a VLBI experiment with a theoretical ~<30 masec precision. We provide an overview of the 10-m system and describe its refurbishment, the data acquisition, and a procedure for fringe fitting that simultaneously estimates the geometric delay used for localization and the dispersive delay from the ionosphere. Using single pulses from the Crab pulsar, we validate the system and localization procedure, and analyze the clock stability between sites, which is critical for phase-referencing an FRB event. We find a localization of 50 masec is possible with the performance of the current system. Furthermore, for sources with insufficient signal or restricted wideband to simultaneously measure both geometric and ionospheric delays, we show that the differential ionospheric contribution between the two sites must be measured to a precision of 1e-8 pc/cc to provide a reasonable localization from a detection in the 400--800 MHz band. Finally we show detection of an FRB observed simultaneously in the CHIME and the Algonquin 10-m telescope, the first FRB cross-correlated in this very long baseline. This project serves as a testbed for the forthcoming CHIME/FRB Outriggers project.

description: In previous work the authors found integral formulas for probabilities in the asymmetric simple exclusion process (ASEP) on the integer lattice. The dynamics are uniquely determined once the initial state is specified. In this note we restrict our attention to the case of step initial condition with particles at the positive integers, and consider the distribution function for the m'th particle from the left. In the previous work an infinite series of multiple integrals was derived for this distribution. In this note we show that the series can be summed to give a single integral whose integrand involves a Fredholm determinant. We use this determinant representation to derive (non-rigorously, at this writing) a scaling limit.

description: De Vrijer has presented a proof of the finite developments theorem which, in addition to showing that all developments are finite, gives an effective reduction strategy computing longest developments as well as a simple formula computing their length. We show that by applying a rather simple and intuitive principle of duality to de Vrijer's approach one arrives at a proof that some developments are finite which in addition yields an effective reduction strategy computing shortest developments as well as a simple formula computing their length. The duality fails for general beta-reduction. Our results simplify previous work by Khasidashvili.
Entanglement transformations using separable operations

Year: 2007
Subjects: subject: Quantum Physics (quant-ph)

description: We study conditions for the deterministic transformation $\ketψ\longrightarrow\ketϕ$ of a bipartite entangled state by a separable operation. If the separable operation is a local operation with classical communication (LOCC), Nielsen's majorization theorem provides necessary and sufficient conditions. For the general case we derive a necessary condition in terms of products of Schmidt coefficients, which is equivalent to the Nielsen condition when either of the two factor spaces is of dimension 2, but is otherwise weaker. One implication is that no separable operation can reverse a deterministic map produced by another separable operation, if one excludes the case where the Schmidt coefficients of $\ketψ$ and are the same as those of $\ketϕ$. The question of sufficient conditions in the general separable case remains open. When the Schmidt coefficients of $\ketψ$ are the same as those of $\ketϕ$, we show that the Kraus operators of the separable transformation restricted to the supports of $\ketψ$ on the factor spaces are proportional to unitaries. When that proportionality holds and the factor spaces have equal dimension, we find conditions for the deterministic transformation of a collection of several full Schmidt rank pure states $\ket{ψ_j}$ to pure states $\ket{ϕ_j}$.

description: In the presence of certain symmetries, three-dimensional Dirac semimetals can harbor not only surface Fermi arcs, but also surface Dirac cones. Motivated by the experimental observation of rotation-symmetry-protected Dirac semimetal states in iron-based superconductors, we investigate the potential intrinsic topological phases in a $C_{4z}$-rotational invariant superconducting Dirac semimetal with $s_{\pm}$-wave pairing. When the normal state harbors only surface Fermi arcs on the side surfaces, we find that an interesting gapped superconducting state with a quartet of Bogoliubov-Dirac cones on each side surface can be realized, even though the first-order topology of its bulk is trivial. When the normal state simultaneously harbors surface Fermi arcs and surface Dirac cones, we find that a second-order time-reversal invariant topological superconductor with helical Majorana hinge states can be realized. The criteria for these two distinct topological phases have a simple geometric interpretation in terms of three characteristic surfaces in momentum space. By reducing the bulk material to a thin film normal to the axis of rotation symmetry, we further find that a two-dimensional first-order time-reversal invariant topological superconductor can be realized if the inversion symmetry is broken by applying a gate voltage. Our work reveals that diverse topological superconducting phases and types of Majorana modes can be realized in superconducting Dirac semimetals.

description: New spectra of NGC 2992 from the Cerro Tololo Inter-American Observatory show that this nearby AGN has changed its type classification to a Seyfert 2 in 2006. It was originally classified as a Seyfert 1.9, and has been previously seen as a Seyfert 1.5 with strong broad Halpha emission. A comparison of the reddening and equivalent hydrogen column density derived for the narrow-line region from these new data with those previously calculated for different regions closer to the nucleus shows them to be very similar, and suggests that these different regions are all being absorbed by the same opacity source, a large 100-pc scale dust lane running across the nucleus. However, obscuration by dust in this lane is probably not responsible for classification changes which occur in only a few years. It is more likely that NGC 2992's observed variations are due to a highly variable ionizing continuum. We therefore conclude that, although NGC 2992 was originally identified as a Seyfert 1.9, this was not because of an oblique viewing angle through the atmosphere of a central dusty torus, but because its active nucleus was identified when it was in a low continuum state.

Both features have a continuous temperature evolution and disappear at Tc = 5.7 K. Moreover, we observe the hexagonal vortex lattice with radially symmetric vortices and a well developed localized state at the vortex cores. The sixfold star shape characteristic of the vortex lattice of the compound 2H-NbSe2 is, together with the charge density wave order (CDW), absent in 2H-NbS2.

Dispersion laws for interacting linear sound and spin excitations are obtained for bulk and surface acoustic waves. We show that ultrasound can generate inverse population of spin levels. Alternatively, the decay of the inverse population of spin levels can generate ultrasound. Possibility of solitary waves of the magnetization accompanied by the elastic twists is demonstrated.

description: The aim of this study is to validate the speech pathology-specific questionnaire for persons with Multiple Sclerosis (SMS) in Turkish. A total of 218 participants were included in the study. The study group was composed of 104 persons diagnosed with MS, and the control group was 114 healthy participants without any neurological deficits. The translated version of the SMS was administered to all participants. Test-retest reliability, internal consistency, construct validity, floor and ceiling effects were investigated. Dysphagia in multiple sclerosis questionnaire (DYMUS) was used for criterion validity. Finally, sensitivity and specificity of the SMS-TR was calculated using a ROC curve analysis. SMS-TR has an excellent internal consistency (Cronbach’s alpha = 0.92). Item-total correlations range between 0.45 and 0.78. The intraclass correlation coefficient (ICC) obtained for the test-retest indicates a good level of reproducibility (ICC = 0.86). According to confirmatory factor analysis, the fit measures of the scale were found to be acceptable. A significant difference was found between the total SMS scores of the study group and the control group (20.6 ± 10.4 and 1.9 ± 2.8, P < 0.001, respectively). A statistically significant correlation was observed between SMS and DYMUS (r = 0.833, P < 0.001). There were no floor and ceiling effects found in the study group. According to the ROC curve analysis, the area under the curve of SMS–TR was 0.98. The optimal cut-off value was 8, with a sensitivity of 91.3% and a specificity of 95.6%. SMS-TR is a valid and reliable patient-reported outcome measure suitable for the assessment of language, speech, and swallowing disorders in persons with MS. A score >8 is an indicator of language, speech, and swallowing pathology for persons.

description: A plethora of research exists in the field of education with regards to what constitutes quality teaching. Tensions exist, however, within this body of research between notions of quality teaching as opposed to notions of quality teachers. This research project seeks to unpack this heavily nuanced notion of “quality”, specifically within the context of Queensland state high schools. The concept of quality is of serious concern for both practising teachers and those in leadership positions, particularly given student results are increasingly used to make determinations about the quality of teachers and of teaching. Hence, while the research points to the need to interpret “quality” with caution, the research has inevitably been drawn into overlapping concerns that touch upon teacher evaluation methods, the role of professional standards for teachers, as well as the impact of socioeconomic factors on school and student success. Through the methodological approach of narrative analysis, the research aimed to elucidate from secondary school principals their perceptions of quality teaching, while also examining the impact of contextual factors within the individual principals’ schools. Data were collected from three Brisbane secondary school principals through face-to-face interviews and various school documents from each site. This study’s findings show that determinations of quality teaching cannot be shaped without consideration of schools’ site-specific contextual factors. Disparity exists between what principals believe quality teaching to be. However, of greater significance is the revelation that principals rely on evidence of student engagement and teacher/student relationships as evidence of quality teaching.

description: Built upon a sample of 134 quasars that was dedicated to a systematic study of \mgii-BAL variability from Yi et al. (2019a), we investigate these quasars showing \mgii-BAL disappearance or emergence with the aid of at least three epoch optical spectra sampled more than 15 yr in the observed frame. We identified 3/3 quasars undergoing pristine/tentative BAL transformations. The incidence of pristine BAL transformations in the sample is therefore derived to be 2.2$_{-1.2}^{+2.2}$\%, consistent with that of high-ionization BAL transformations from the literature. Adopting an average \mgii-BAL disappearance timescale of rest-frame 6.89 yr among the six quasars, the average characteristic lifetime of \mgii\ BALs in the sample is constrained to be $>$160 yr along our line of sight. There is a diversity of BAL-profile variability observed in the six quasars, probably reflecting a variety of mechanisms at work. Our investigations of \mgii-BAL transitions, combined with observational studies of BAL transitions from the literature, imply an overall FeLoBAL/LoBAL$\rightarrow$HiBAL/non-BAL transformation sequence along with a decrease in reddening. This sequence is consistent with the evacuation models for the origin of commonly seen blue quasars, in which LoBAL quasars are in a shorted-lived, blowout phase.

description: Wireless communication is susceptible to adversarial eavesdropping due to the broadcast nature of the wireless medium. In this paper it is shown how eavesdropping can be alleviated by exploiting the superposition property of the wireless medium. A wiretap channel with a helping interferer (WT-HI), in which a transmitter sends a confidential message to its intended receiver in the presence of a passive eavesdropper, and with the help of an independent interferer, is considered. The interferer, which does not know the confidential message, helps in ensuring the secrecy of the message by sending independent signals. An achievable secrecy rate for the WT-HI is given. The results show that interference can be exploited to assist secrecy in wireless communications. An important example of the Gaussian case, in which the interferer has a better channel to the intended receiver than to the eavesdropper, is considered. In this situation, the interferer can send a (random) codeword at a rate that ensures that it can be decoded and subtracted from the received signal by the intended receiver but cannot be decoded by the eavesdropper. Hence, only the eavesdropper is interfered with and the secrecy level of the confidential message is increased.

description: Past research highlights the importance of evaluating word learning abilities to build understanding of an individual’s language-learning capacity and make evidence-informed decisions in speech-language pathology practice. However, little research has explored vocabulary and word learning assessment practices among speech-language pathologists (SLPs). This pilot, exploratory study aimed to explore current assessment practices and guide translation of research to practice among SLPs who work with children of all ages. SLPs (N = 127) from three predominantly English-speaking countries (Australia, USA, and UK) completed an online survey. The survey explored methods and purposes for assessing vocabulary knowledge and word learning skills via binary and multiple-choice questions. Responses to three open-ended questions were analysed using conventional content analysis. The survey also asked about perspectives regarding assessment practices with individuals from culturally and linguistically diverse (CALD) backgrounds. Of the surveyed SLPs, 118 (92%) reported using norm-referenced measures of vocabulary, with 27 reporting additional use of non-normed measures. Seventy-seven SLPs (61%) reported that they measure word learning skills, and 20 of these SLPs used dynamic assessment procedures to evaluate word learning. Responding SLPs across all three countries reported using vocabulary and word learning assessment data in a variety of ways (e.g. to support diagnostic decision-making). Regarding the use of standardised, norm-referenced vocabulary assessments with individuals from CALD backgrounds, SLPs reported concerns regarding poor cultural sensitivity and limited access to alternative methods. The findings highlight the need for further development and dissemination of accessible resources to support SLPs’ implementation of word learning assessment, including resources for dynamic assessment. This is especially critical considering the established limitations associated with using standardised, norm-referenced tests with minority groups who are underrepresented in standardisation samples.

description: We deal with a class of abstract nonlinear stochastic models, which covers many 2D hydrodynamical models including 2D Navier-Stokes equations, 2D MHD models and 2D magnetic Bénard problem and also some shell models of turbulence. We first prove the existence and uniqueness theorem for the class considered. Our main result is a Wentzell-Freidlin type large deviation principle for small multiplicative noise which we prove by weak convergence method.

description: Purpose: Speed and accuracy of lexical access change with healthy ageing and neurodegeneration. While a word's immediate phonological neighbourhood density (i.e. words differing by a single phoneme) influences access, connectivity to all words in the phonological network (i.e. closeness centrality) may influence processing. This study aimed to investigate the effect of closeness centrality on speed and accuracy of lexical processing pre- and post- a single word-training session in healthy younger and older adults, and adults with logopenic primary progressive aphasia (lvPPA), which affects phonological processing. Method: Participants included 29 young and 17 older healthy controls, and 10 adults with lvPPA. Participants received one session of word-training on words with high or low closeness centrality, using a picture-word verification task. Changes in lexical decision reaction times (RT) and accuracy were measured. Result: Baseline RT was unaffected by age and accuracy was at ceiling for controls. Post-training, only young adults' RT were significantly faster. Adults with lvPPA were slower and less accurate than controls at baseline, with no training effect. Closeness centrality did not influence performance. Conclusion: Absence of training effect for older adults suggests higher threshold to induce priming, possibly associated with insufficient dosage or fatigue. Implications for word-finding interventions with older adults are discussed.

description: In 2003, we initiated a long-term adaptive optics campaign to study the orbit of various main-belt asteroidal systems. Here we present a consistent solution for the mutual orbits of four binary systems: 22 Kalliope, 45 Eugenia, 107 Camilla and 762 Pulcova. With the exception of 45 Eugenia, we did not detect any additional satellites around these systems although we have the capability of detecting a loosely-bound fragment (located at 1/4 x RHill) that is ~40 times smaller in diameter than the primary. The common characteristic of these mutual orbits is that they are roughly circular. Three of these binary systems belong to a C-"group" taxonomic class. Our estimates of their bulk densities are consistently lower (~1 g/cm3) than their associated meteorite analogs, suggesting an interior porosity of 30-50% (taking CI-CO meteorites as analogs). 22 Kalliope, a W-type asteroid, has a significantly higher bulk density of ~3 g/cm3, derived based on IRAS radiometric size measurement. We compare the characteristics of these orbits in the light of tidal-effect evolution.

description: Numerous claims have been made about the benefits of activity-based working (ABW) on workers’ health and work performance. Yet, it is unclear if these claims are proven. This systematic review aims to establish whether there is an evidence base for the effects of ABW on health, work performance and perceptions of the work environment. Eight databases were searched in September 2016. Three reviewers independently screened titles and abstracts and assessed the studies and extracted the data. Seventeen studies involving 36,039 participants were included. The study designs varied in rigorousness from qualitative studies to pre–post-trials and in sample size ranging from 12 to 11,799. This review found that ABW has positive merits in the areas of interaction, communication, control of time and space, and satisfaction with the workspace; however, it is unfavourable for concentration and privacy. For physical and mental health, the evidence is equivocal. ABW seems to be a promising concept that can be implemented and promoted based on some benefits for work performance and perceptions of the work environment when it is coupled with appropriate management support and organization. More high-quality research is needed to strengthen the evidence base further and establish its health effects.

description: If I is a nilpotent ideal in a $\mathbb{Q}$-algebra $A$, Goodwillie defined two isomorphisms from $K_*(A,I)$ to negative cyclic homology, $HN_*(A,I)$. One is the relative version of the absolute Chern character, and the other is defined using rational homotopy theory. The question of whether they agree was implicit in Goodwillie's 1986 Annals paper. In this paper, we show that the two isomorphisms agree. Here are three applications. 1.Cathelineau proved that the rational homotopy character is compatible with the $λ$-filtration. It follows that the relative Chern character is also compatible with this filtration for nilpotent ideals. 2.This agreement, together with Cathelineau's result, was used by the authors and Haesemeyer to show that the absolute Chern character, from $K(A)$ to $HN(A)$, is compatible with the $λ$-filtration for every commutative $\mathbb{Q}$-algebra. This is the main result of Infinitesimal cohomology and the Chern character to negative cyclic homology, arXiv:math/0703133v1. 3.This agreement can be used to strengthen Ginot's results in "Formules explicites pour le charactere de Chern en $K$-théorie algébrique", Ann. Inst. Fourier 54 (2004).

description: We present a method for learning generalized Hamiltonian decompositions of ordinary differential equations given a set of noisy time series measurements. Our method simultaneously learns a continuous time model and a scalar energy function for a general dynamical system. Learning predictive models in this form allows one to place strong, high-level, physics inspired priors onto the form of the learnt governing equations for general dynamical systems. Moreover, having shown how our method extends and unifies some previous work in deep learning with physics inspired priors, we present a novel method for learning continuous time models from the weak form of the governing equations which is less computationally taxing than standard adjoint methods.

description: We propose the phase diagram of a new pseudo-ternary compound, CoMnGe_{1-x}Sn_{x}, in the range x less than or equal to 0.1. Our phase diagram is a result of magnetic and calometric measurements. We demonstrate the appearance of a hysteretic magnetostructural phase transition in the range x=0.04 to x=0.055, similar to that observed in CoMnGe under hydrostatic pressure. From magnetisation measurements, we show that the isothermal entropy change associated with the magnetostructural transition can be as high as 4.5 J/(K kg) in a field of 1 Tesla. However, the large thermal hysteresis in this transition (~20 K) will limit its straightforward use in a magnetocaloric device.
