A study of selected industrial minerals for water treatment and supplementary cementing materials
Creators: name: Entesari, Alireza
Publisher: name: University of British Columbia
Year: 2009

description: A study was conducted on three natural mineral materials referred to as basalt, scoria, and calcined shale. These materials were provided by an industrial mineral producer in British Columbia. The main objectives of this study are, to evaluate the selected materials for treatment of metal contaminated effluents by adsorption, and to assess the possibility of replacing cement with the materials and to evaluate the performance of the cement replaced mortars. In this research study, adsorption tests were conducted to asses the possibility of removing cationic and anionic metal ions from prepared and sampled oil refinery, and mine water effluents. Results of these tests indicate that the calcined shale material was an efficient adsorbent removing more than 99.8% of the copper from the effluent. Basalt material is a natural adsorbent that is highly capable of removing more than 99.9% molybdenum and arsenic ions and performs better than activated carbon. The treated effluents meet the regulatory limits of the Canadian Fisheries Act. The adsorption process when supplements the high density sludge (HDS) treatment, presents a reliable treatment process in removing metal ions in mine water to the regulatory limits. In particular, post treatment should serve to reduce fluctuations in the effluent discharge level. The materials are assessed as natural pozzolans according to ASTM C618 "Standard specifications for coal fly ash and raw or calcined natural pozzolan for use as a mineral admixture in Portland cement concrete". Results indicate that the materials comply with the standard specifications. Naturally calcined shale is a highly desirable natural pozzolan in which the calcination process to enhance the physical properties of the pozzolan occurs naturally requiring no energy consumption. Over time, natural pozzolan mortars gained higher compressive strength than that of fly ash and control mortars, making them suitable for mass concrete applications where early high strength is not required and low heat of hydration is favorable. Further testing is required to evaluate the kinetics of the metal adsorption processes and to assess the possibility of regenerating the adsorbent bed. Additional testing is recommended to evaluate the performance of the metal loaded adsorbents as pozzolans for long term storage. Leaching tests need to be conducted in order to assess the leachability of adsorbed metal ions.

description: Diamond quantum sensors are sensitive to weak microwave magnetic fields resonant to the spin transitions. However the spectral resolution in such protocols is limited ultimately by sensor lifetime. Here we demonstrate a heterodyne detection method for microwaves (MW) leading to a lifetime independent spectral resolution in the GHz range. We reference the MW-signal to a local oscillator by generating the initial superposition state from a coherent source. Experimentally we achieve a spectral resolution below $1\ \rm{Hz}$ for a $4\ \rm{GHz}$ signal far below the sensor lifetime limit of kilohertz. Furthermore we show control over the interaction of the MW-field with the two level system by applying dressing fields, pulsed Mollow absorption and Floquet dynamics under strong longitudinal radio frequency drive. While pulsed Mollow absorption leads to highest sensitivity, the Floquet dynamics allows robust control independent from the systems resonance frequency. Our work is important for future studies in sensing weak microwave signals in wide frequency range with high spectral resolution.

description: We present a wide field, sub-arcminute resolution VLA image of the Galactic Center region at 330 MHz. With a resolution of ~ 7" X 12" and an RMS noise of 1.6 mJy/beam, this image represents a significant increase in resolution and sensitivity over the previously published VLA image at this frequency. The improved sensitivity has more than tripled the census of small diameter sources in the region, has resulted in the detection of two new Non Thermal Filaments (NTFs), 18 NTF candidates, 30 pulsar candidates, reveals previously known extended sources in greater detail, and has resulted in the first detection of Sagittarius A* in this frequency range.

description: O objetivo desta comunicação é relatar o andamento de uma pesquisa que visa avaliar a eficiência econômica de programas de seguro rural no contexto brasileiro, usando como base o atual projeto do governo de criação do Fundo de Catástrofe. A potencialidade do seguro rural no Brasil é discutida e avaliada tendo como pano de fundo a atual política agrícola brasileira, fundamentada principalmente no incentivo ao crédito rural. A intenção é verificar a eficiência dos gastos do governo com as políticas voltadas ao setor agropecuário. Neste sentido, são apresentadas e discutidas as experiências internacionais que se utilizam o seguro rural ao produtor, em detrimento dos subsídios diretos ao crédito. O artigo conclui que o Fundo de Catástrofe poderá permitir não apenas o crescimento consistente e significativo do mercado de seguro rural, como também poderá ser um importante instrumento anticíclico de apoio aos agricultores. Essa inovadora ação de governo poderá significar um grande incentivo para a agricultura brasileira, constituindo-se em um passo extremamente importante para conferir maior sustentabilidade ao processo produtivo e ao agronegócio, proporcionando maior estabilidade de renda, tranqüilidade social e geração de empregos para os agricultores e suas famílias.----------------------------------------------The objective of this paper is to report a research in progress aimed at evaluating the economic efficiency of crop insurance in Brazil by using a proposed government project called Catastrophic Fund. The potentiality of crop insurance in Brazil is discussed and evaluated in a Brazilian agricultural policy background context mainly emphasized by rural credit incentives. The major purpose is to analyze the efficiency of government expenses in public policies in the agricultural sector. Therefore, international experience using crop insurance is reviewed and discussed for producers using crop insurance opposite to direct credit subsidies. The paper concludes that the Catastrophic Fund could permit not only a consistent and significant increase in the crop insurance market, but could also become an important anticyclical instrument support support to farmers. This innovative government action could result in an amazing incentive to Brazilian agriculture, bringing more sustainability to production and the agribusiness, resulting in more income stability, social tranquility and employment generation for farmers and their families.

description: The light-cone Hamiltonians for spin 1 and spin 2 fields, describing both the pure and the maximally supersymmetric theories, may be expressed as quadratic forms. In this paper, we show that this feature extends to light-cone higher spin theories. To first order in the coupling constant, we prove that the higher spin Hamiltonians, with and without supersymmetry, are quadratic forms. Scattering amplitude structures emerge naturally in this framework and we relate the momentum space vertex in a supersymmetric higher spin theory to the corresponding vertex in the N=4 Yang-Mills theory.

description: We investigate OZI rule violation in omega and phi-meson photoproduction off nucleons. Data on the total cross sections indicate a large phi/omega ratio of about 0.8 at the maximal available photon energy that is in good agreement with expectations from QCD. On the other hand, data at large four momentum transfer exhibit a ratio of about 0.07, showing that the perturbative QCD regime is not approached at |t| > 2 GeV^2 and photon energies E_γ< 4 GeV. The anomanously large phi/omega ratio at low energies, that is close to the reaction threshold, remains to be explained within nonperturbative QCD.

Gauge Symmetry and its Implications for the Schwinger-Dyson Equations

description: Gauge theories have been a cornerstone of the description of the world at the level of the fundamental particles. The Lagrangian or the action describing the corresponding interactions is invariant under certain gauge transformations. This symmetry is reflected in terms of the Ward-Green-Takahashi (or the Slavnov-Taylor) identities which relate various Green functions among each other, and the Landau-Khalatnikov-Fradkin transformations which relate a Green function in a particular gauge to it in an arbitrary covariant one. As an outcome, all physical observables should be independent of the choice of the covariant gauge parameter. The most systematic scheme to solve quantum field theories (QFT) is perturbation theory where the above-mentioned identities are satisfied at every order of approximation. This feature is exploited highly usefully as a verification of the results obtained after time- and effort-consuming exercises. As it stands, not all natural phenomena are realized in the perturbative regime of QFTs. Therefore, one is inevitably led to make efforts to solve these theories in a non perturbative fashion. A natural starting point for such studies in the continuum are the Schwinger-Dyson Equations (SDE). One of the most undesirable features associated with their non perturbative truncation is the loss of highly and rightly esteemed gauge invariance rendering the predictions less reliable. Arguably, the only hope we have to recuperate the credibility of the results is to employ only such truncation schemes which yield predictions that match onto the blindly reliable perturbative ones at every order of approximation. It is a highly difficult task but not impossible.

description: O agronegócio vem contribuindo com superávits expressivos na balança comercial nos últimos anos. Esses superávits serviram para contrabalançar déficits em outros setores e foram fundamentais para a obtenção dos grandes superávits da balança comercial a partir de 2002 O Brasil, na década de noventa, assumiu posição de destaque como importante receptor de investimento direto estrangeiro (IDE). O objetivo deste trabalho é avaliar até que ponto a entrada de IDE no agronegócio levou a um aumento da exportação do setor. O método utilizado na investigação foi a análise multivariada discriminante. Esse método é bastante adequado, já que possibilita identificar grupos de atividades que mais exportam e, assim, fornece ferramentas de planejamento às agências governamentais na construção de políticas que possibilitem alocação do IDE de acordo com os objetivos da política econômica. Os resultados mostraram que o volume de IDE não possui qualquer relação na distinção entre os grupos de atividades que mais exportam, o que sugere que seu montante não está relacionado com maiores quantidades exportadas. -------------------------------------------------Agribusiness has been generating huge trade surpluses in the last few years. These surpluses were crucial because they compensated trade deficits in other areas and allowed Brazil to have a general trade surplus from 2002 on. Brazil assumed an important position as receiver of foreign direct investments (FDI) in the nineties. The objective of this paper is to evaluate whether the incoming of FDI caused an increase on agribusiness exports. The methodology was multivariate discriminant analysis. This method is suitable because it allows the identification of more exporting activities and provides planning tools to policy makers to design FDI allocation policies. Results showed that the volume of FDI does not have any relationship in the distinction of more exporting activities, which suggests that this amount is not related to more exports.

description: O principal objetivo desta comunicação é relatar o andamento de uma pesquisa sobre o impacto da política de crédito rural concedido a produtores rurais e cooperativas no Brasil. Com este propósito, foram utilizados dados sobre o valor e alocação dos financiamentos concedidos pelo Sistema Nacional de Crédito Rural (SNCR). A análise é feita em termos regionais, por finalidade, atividade, e classificação do produtor. Adicionalmente, a partir de 1995, foram analisados, os recursos disponibilizados para o apoio financeiro da agricultura familiar. Os resultados mostram que o crédito rural vem apresentando uma desconcentração em termos do tipo de produtor, mas continua concentrado na finalidade de custeio, na atividade agrícola e em termos regionais, sendo as regiões Norte e Nordeste as menos beneficiadas. Conclui-se que a estabilização econômica trouxe benefícios para a agricultura como o abandono da correção monetária no crédito rural. Mas esta só foi efetivamente obtida através da valorização cambial e juros reais elevados, que perdurando durante vários anos (1993-1998), causaram em um primeiro momento, expressivo crescimento das dívidas externa e interna do país.----------------------------------------------The objective of this paper is to report a research in progress aimed at evaluating the impact of agricultural credit given to farmers and cooperatives in Brazil. For this purpose value and allocation data of loans given to farmers and cooperatives by the Brazilian Rural Credit System (SNCR) were used. The analysis takes into account total amount, regional distribution, type of credit, economic activity and farmer type. Additionally, after 1995, the financial resources available for family agriculture are also analyzed. The paper concludes that economic stabilization brought real benefits to agriculture as the end of monetary correction in farm credit. But this was only effectively reached by exchange valorization and high real interest, that persisted for several years (1993-1998), that in a first moment to an expressive increase in internal e foreign debt.

description: Recently we find several candidates of quantum algorithms that may be implementable in near-term devices for estimating the amplitude of a given quantum state, which is a core sub- routine in various computing tasks such as the Monte Carlo methods. One of those algorithms is based on the maximum likelihood estimate with parallelized quantum circuits. In this paper, we extend this method so that it incorporates the realistic noise effect, and then give an experimental demonstration on a superconducting IBM Quantum device. The maximum likelihood estimator is constructed based on the model assuming the depolarization noise. We then formulate the problem as a two-parameters estimation problem with respect to the target amplitude parameter and the noise parameter. In particular we show that there exist anomalous target values, where the Fisher information matrix becomes degenerate and consequently the estimation error cannot be improved even by increasing the number of amplitude amplifications. The experimental demonstration shows that the proposed maximum likelihood estimator achieves quantum speedup in the number of queries, though the estimation error saturates due to the noise. This saturated value of estimation error is consistent to the theory, which implies the validity of the depolarization noise model and thereby enables us to predict the basic requirement on the hardware components (particularly the gate error) in quantum computers to realize the quantum speedup in the amplitude estimation task.

This paper focuses on the case of quasi-one-dimensional metals, where it is known experimentally that antiferromagnetism is in close proximity to triplet superconductivity in the temperature versus pressure phase diagram. Over a narrow range of pressures, the authors propose an intermediate non-uniform phase consisting of alternating insulating antiferromagnetic and triplet superonducting stripes.

description: In today’s increasingly complex employment market, cognitive flexibility emerges as a critical attribute for individuals to adapt and thrive. Despite efforts to understand the relationships among dispositional traits, learning experiences, job search self-efficacy (JSSE), and job search behaviours, cognitive flexibility remains underexplored. This doctoral research thesis “by publication” proposes the Cognitive Flexibility Job Search Self-Efficacy (CF-JSSE) model in a conceptual paper and reports on tests of its hypothesized paths in three empirical studies. The first two studies are methodological in nature and provide essential groundwork for understanding and addressing the nuances of cognitive flexibility’s measurement; thus, these studies lay the foundation for the final study testing the CF-JSSE model. The CF-JSSE model suggests cognitive flexibility as a vital process moderating relationships between dispositional traits and JSSE, as well as learning experiences and JSSE. The first study (n = 249) explored differences in cognitive flexibility outcomes from neuropsychological tests administered online and in-person. The second study (n = 92) examined the performance outcomes of these cognitive flexibility tests on different devices (e.g., Apple MacBook, Windows laptop, Apple iPhone or iPad, Android phone or tablet). Findings reveal significant differences in results depending on administration mode and device used. The final study (n = 138) examined the CF-JSSE model, showing preliminary support for cognitive flexibility's moderating role between dispositional traits and JSSE. Overall, these contributions provide both theoretical insights and practical guidance for enhancing job seekers' self-efficacy and success.

Interpreting the High Frequency QPO Power Spectra of Accreting Black Holes

Publisher: name: arXiv

Subjects: subject: Astrophysics (astro-ph)
subject: FOS: Physical sciences

description: In the context of a relativistic hot spot model, we investigate different physical mechanisms to explain the behavior of quasi-periodic oscillations (QPOs) from accreting black holes. The locations and amplitudes of the QPO peaks are determined by the ray-tracing calculations presented in Schnittman & Bertschinger (2004a): the black hole mass and angular momentum give the geodesic coordinate frequencies, while the disk inclination and the hot spot size, shape, and overbrightness give the amplitudes of the different peaks. In this paper additional features are added to the existing model to explain the broadening of the QPO peaks as well as the damping of higher frequency harmonics in the power spectrum. We present a number of analytic results that closely agree with more detailed numerical calculations. Four primary pieces are developed: the addition of multiple hot spots with random phases, a finite width in the distribution of geodesic orbits, Poisson sampling of the detected photons, and the scattering of photons from the hot spot through a corona of hot electrons around the black hole. Finally, the complete model is used to fit the observed power spectra of both type A and type B QPOs seen in XTE J1550-564, giving confidence limits on each of the model parameters.

description: A última década do século passado pode ser caracterizada como um curto período de transição na demografia rural brasileira, pois seu início delimitou a interrupção da pretérita tendência de declínio e foi sucedida pelo recente período de lento crescimento da população rural, resultante da expansão do pessoal ocupado em atividade não-agrícola. As descrições disponíveis dessa tendência que inaugurou um novo mundo rural, ainda não demoveram a suspeição sobre sua genérica dispersão na zona rural, pois essa área contém algumas localidades com aglomerações de domicílios minimamente urbanizadas. O intuito básico deste artigo é mostrar os resultados da averiguação, feita com os microdados da PNAD do período de 2001-2006 relativos à União, grandes regiões e estado do Paraná, acerca da dispersão da tendência demográfica definidora do “novo rural” brasileiro, especialmente na zona rural propriamente dita. A conclusão relevante é que se deve rejeitar a suposição de que aumento da PEA com ocupação não-agrícola concentra-se nas localidades rurais minimamente urbanizadas, ou de menor densidade populacional. Além disso, em função do atual definição de PEA se torna relevante que a descrição do perfil da economia da nova ruralidade brasileira seja expandida para se acomodar o tradicional segmento composto pelas atividades de subsistência. ------------------------------------------------------------Past century’s past decade may be characterized by a short transition period in Brazilian rural demography. It’s start marked the interruption of the past declining trend succeeded by the recent slow growth of rural population resulting from expanding non- agricultural occupied labor. Available description of this trend, which inaugurated a new rural world, did not demote suspicions about its generic dispersion in the rural area yet, for there one can find some clusters of households located in minimally urbanized rural places. The basic aim of this paper is to show findings of the research, using 2001-2006 PNAD microdata for Brazil, large regions and the state of Paraná; about the demographic trend dispersion which defines the Brazilian “new rural”, especially in the rural area itself. The relevant conclusion is that one should reject the hypothesis that PEA increases concentrates in minimally urbanized rural places or in those of lower population density. Besides, giving the current PEA definition, it becomes important to describe the economic profile of the new Brazilian rurality including the traditional subsistence sector.

description: The primary objective of helmet design continues to be the prevention of traumatic brain injuries. Yet, achieving an optimal user experience, including aspects such as fit, thermal comfort, breathability, waterproofing, and reusability, is increasingly significant. Thus, designing helmets with multifunctional performance represents the latest technological frontier for safety devices. This study draws inspiration from the morphology of Coscinodiscus species diatoms to develop a biomimetic material replicating their cellular structure and multifunctionality. Unlike its biological counterpart, the synthetic material is engineered as the inner liner for multi impact helmets, suited for urban sports and micro mobility applications. The architecture of the material is modeled using computer aided design tools, and its energy absorption capabilities are analyzed through finite element modeling and quasi static compression tests on 3D printed elastomeric samples. Performance optimization is achieved through a parametric approach. The results demonstrate that the material exhibits energy absorption comparable to cellular materials like honeycombs, while offering lightweight properties, breathability, and resistance to atmospheric agents. This biomimetic design marks a significant advancement in high performance safety equipment.

description: O presente trabalho tem por objetivo analisar as exportações brasileiras de carne de frango no período de 1996 a 2006, bem como a tendência que vem acontecendo nos últimos anos em relação a uma possível mudança no perfil do produto exportado, de maneira a verificar se a cadeia de carne de frango paranaense, mais especificamente da Mesorregião Oeste do Paraná, tem se adaptado a essa demanda em ascensão. Primeiramente, é feita uma análise sobre a evolução da produção mundial do produto, caracterizando a exportação, importação, consumo e os países envolvidos que mais se destacam em relação a essa cadeia produtiva. Posteriormente são identificados os frigoríficos de abate de frango que compõem a Mesorregião Oeste do Paraná, de maneira a demonstrar a forte concentração de produção. Por fim, é feita uma análise em relação à produção brasileira de carne de frango inteiro, em pedaços e industrializados, que demonstra a tendência de aumento na procura por carne de frango com maior valor agregado, ou seja, em pedaços e industrializados, fator este que demanda atenção por parte dos frigoríficos instalados na região, já que nem todos estão habilitados a este tipo de exportação.----------------------------------------------This study aims to examine the Brazilian exports of chicken meat that occurred in the period from 1996 at 2006, and the trend that is happening in recent years in relation to a possible change in the profile of the exported product in order to verify if the chicken chain meat from Parana State, specifically in the West of Parana State Region has adapted to this demand. Firstly, an analysis is made on the evolution of global production of the product as export, import, consumption and the countries involved that most stand out in relation to the productive chain. Subsequently are identified the slaughterhouses in the West of Parana State region in order to demonstrate the strong concentration of production. Finally, an analysis is made on the production of Brazilian chicken meat production and chicken whole, in pieces and industrialized, which demonstrates the strong trend of an increase in demand for chicken meat with higher value added, namely pieces and industrialized, this factor, which demand attention from slaughterhouses installed in the region, because not all are entitled to this kind of export.

description: Environmental disasters such as flash floods are becoming more and more prevalent and carry an increasing burden on human civilization. They are usually unpredictable, fast in development, and extend across large geographical areas. The consequences of such disasters can be reduced through better monitoring, for example using mobile sensing platforms that can give timely and accurate information to first responders and the public. Given the extended scale of the areas to monitor, and the time-varying nature of the phenomenon, we need fast algorithms to quickly determine the best sequence of locations to be monitored. This problem is very challenging: the present informative mobile sensor routing algorithms are either short-sighted or computationally demanding when applied to large scale systems. In this paper, a real-time sensor task scheduling algorithm that suits the features and needs of city-scale environmental monitoring tasks is proposed. The algorithm is run in forward search and makes use of the predictions of an associated distributed parameter system, modeling flash flood propagation. It partly inherits the causal relation expressed by a search tree, which describes all possible sequential decisions. The computationally heavy data assimilation steps in the forward search tree are replaced by functions dependent on the covariance matrix between observation sets. Taking flood tracking in an urban area as a concrete example, numerical experiments in this paper indicate that this scheduling algorithm can achieve better results than myopic planning algorithms and other heuristics based sensor placement algorithms. Furthermore, this paper relies on a deep learning-based data-driven model to track the system states, and experiments suggest that popular estimation techniques have very good performance when applied to precise data-driven models.

description: The number of robots deployed in our daily surroundings is ever-increasing. Even in the industrial set-up, the use of coworker robots is increasing rapidly. These cohabitant robots perform various tasks as instructed by co-located human beings. Thus, a natural interaction mechanism plays a big role in the usability and acceptability of the robot, especially by a non-expert user. The recent development in natural language processing (NLP) has paved the way for chatbots to generate an automatic response for users' query. A robot can be equipped with such a dialogue system. However, the goal of human-robot interaction is not focused on generating a response to queries, but it often involves performing some tasks in the physical world. Thus, a system is required that can detect user intended task from the natural instruction along with the set of pre- and post-conditions. In this work, we develop a dialogue engine for a robot that can classify and map a task instruction to the robot's capability. If there is some ambiguity in the instructions or some required information is missing, which is often the case in natural conversation, it asks an appropriate question(s) to resolve it. The goal is to generate minimal and pin-pointed queries for the user to resolve an ambiguity. We evaluate our system for a telepresence scenario where a remote user instructs the robot for various tasks. Our study based on 12 individuals shows that the proposed dialogue strategy can help a novice user to effectively interact with a robot, leading to satisfactory user experience.

description: Remote sensing object detection is particularly challenging due to the high resolution, multi-scale features, and diverse ground object characteristics inherent in satellite and UAV imagery. These challenges necessitate more advanced approaches for effective object detection in such environments. While deep learning methods have achieved remarkable success in remote sensing object detection, they typically rely on large amounts of labeled data. Acquiring sufficient labeled data, particularly for novel or rare objects, is both challenging and time-consuming in remote sensing scenarios, limiting the generalization capabilities of existing models. To address these challenges, few-shot learning (FSL) has emerged as a promising approach, aiming to enable models to learn new classes from limited labeled examples. Building on this concept, few-shot object detection (FSOD) specifically targets object detection challenges in data-limited conditions. However, the generalization capability of FSOD models, particularly in remote sensing, is often constrained by the complex and diverse characteristics of the objects present in such environments. In this paper, we propose the Generalization-Enhanced Few-Shot Object Detection (GE-FSOD) model to improve the generalization capability in remote sensing FSOD tasks. Our model introduces three key innovations: the Cross-Level Fusion Pyramid Attention Network (CFPAN) for enhanced multi-scale feature representation, the Multi-Stage Refinement Region Proposal Network (MRRPN) for more accurate region proposals, and the Generalized Classification Loss (GCL) for improved classification performance in few-shot scenarios. Extensive experiments on the DIOR and NWPU VHR-10 datasets show that our model achieves state-of-the-art performance for few-shot object detection in remote sensing.
Behind the horizon of the charged anti-de Sitter black hole

description: There is a correspondence between the supergravity in AdS₅ x S⁵ space and N = 4 super-Yang-Mills theory. In this sense, we study the region inside the event horizon of charged black holes in five dimensional asymptotically anti-de Sitter space, using the two-point correlation functions dominated by the spacelike geodesies between the operators at different sides of the asymptotical boundary. With some null perturbation, we find the spacetime structure is changed, as well as the correlation functions, providing a method of scanning the region between inner and out horizons. Surprisingly, the twosided correlators we calculate seem to be geometrically protected from the instability of the inner horizon.

description: This paper establishes the global asymptotic equivalence between a Poisson process with variable intensity and white noise with drift under sharp smoothness conditions on the unknown function. This equivalence is also extended to density estimation models by Poissonization. The asymptotic equivalences are established by constructing explicit equivalence mappings. The impact of such asymptotic equivalence results is that an investigation in one of these nonparametric models automatically yields asymptotically analogous results in the other models.

description: Although variational autoencoders (VAE) are successfully used to obtain meaningful low-dimensional representations for high-dimensional data, the characterization of critical points of the loss function for general observation models is not fully understood. We introduce a theoretical framework that is based on a connection between $β$-VAE and generalized linear models (GLM). The equality between the activation function of a $β$-VAE and the inverse of the link function of a GLM enables us to provide a systematic generalization of the loss analysis for $β$-VAE based on the assumption that the observation model distribution belongs to an exponential dispersion family (EDF). As a result, we can initialize $β$-VAE nets by maximum likelihood estimates (MLE) that enhance the training performance on both synthetic and real world data sets. As a further consequence, we analytically describe the auto-pruning property inherent in the $β$-VAE objective and reason for posterior collapse.
