description: While being it extremely important, many Exploratory Data Analysis (EDA) systems have the inhability to perform classification and visualization in a continuous basis or to self-organize new data-items into the older ones (evenmore into new labels if necessary), which can be crucial in KDD - Knowledge Discovery, Retrieval and Data Mining Systems (interactive and online forms of Web Applications are just one example). This disadvantge is also present in more recent approaches using Self-Organizing Maps. On the present work, and exploiting past sucesses in recently proposed Stigmergic Ant Systems a robust online classifier is presented, which produces class decisions on a continuous stream data, allowing for continuous mappings. Results show that increasingly better results are achieved, as demonstraded by other authors in different areas.

description: Recent water sector reforms, increased scarcity and vulnerability of existing water resources, combined with declining public funding available for large-scale infrastructure investment in the sector have led to an increased awareness by the Government of Vietnam for the need to analyze water resource allocation and use in an integrated fashion, at the basin scale, and from an economic efficiency perspective. This paper presents the development, application, and results from an integrated economic-hydrologic river basin model for the Dong Nai River Basin in southern Vietnam that attempts to address these issues. The model framework takes into account the sectoral structure of water users (agriculture, industry, hydropower, households, and the environment), the location of water-using regions, and the institutions for water allocation in the basin. Water benefit functions are developed for the major water uses subject to physical, system control, and policy constraints. Based on this modeling framework, policies that can affect water allocation and use at the basin level, including both basin-specific and general macroeconomic policies, are analyzed.

Subjects: subject: High Energy Physics - Phenomenology (hep-ph)

description: We consider the possibility of neutrinos being Dirac particles and study minimal mass matrices with as much zero entries as possible. We find that up to 5 zero entries are allowed. Those matrices predict one vanishing mass state, CP conservation and U_{e3} either zero or proportional to R, where R is the ratio of the solar and atmospheric Δm^2. Matrices containing 4 zeros can be classified in categories predicting U_{e3} = 0, U_{e3} \neq 0 but no CP violation or |U_{e3}| \neq 0 and possible CP violation. Some cases allow to set constraints on the neutrino masses. The characteristic value of U_{e3} capable of distinguishing some of the cases with non-trivial phenomenological consequences is about R/2 \sin 2 θ_{12}. Matrices containing 3 and less zero entries imply (with a few exceptions) no correlation for the observables. We outline models leading to the textures based on the Froggatt-Nielsen mechanism or the non-Abelian discrete symmetry D_4 \times Z_2.

description: This work presents a novel approach for speaker diarization to leverage lexical information provided by automatic speech recognition. We propose a speaker diarization system that can incorporate word-level speaker turn probabilities with speaker embeddings into a speaker clustering process to improve the overall diarization accuracy. To integrate lexical and acoustic information in a comprehensive way during clustering, we introduce an adjacency matrix integration for spectral clustering. Since words and word boundary information for word-level speaker turn probability estimation are provided by a speech recognition system, our proposed method works without any human intervention for manual transcriptions. We show that the proposed method improves diarization performance on various evaluation datasets compared to the baseline diarization system using acoustic information only in speaker embeddings.

description: In the early 1990s, Thailand launched an ambitious program of decentralized governance, conferring greater responsibilities upon sub-district administrations and providing fiscal opportunities for local development planning. This process was reinforced by Thailand’s new Constitution of 1997, which explicitly assures individuals, communities and local authorities the right to participate in the management of natural resources. Drawing on a study of water management in the Mae Sa watershed, northern Thailand, this study analyzes to what extent the constitutional right for participation has been put into practice. To this end, a stakeholder analysis was conducted in the watershed, with a focus on the local people’s interests and strategies in water management and the transformation of participatory policies through government agencies at the local level. Government line departments were categorized into development- and conservation-oriented agencies. While government officers stressed the importance of stakeholder inclusion and cooperation with the local people, there is a sharp contrast between the official rhetoric and the reality on the ground. The analysis reveals that government officers, particularly in the conservation-oriented agencies, are not disposed to devolve power to lower levels due to the fear of losing their traditional mandate and persistent stereotypes about local communities’ incompetence to manage water resources in a sustainable way. On their part, villagers do not perceive a tangible change in the implementation of water policies and retain a widely negative image of government officers. In conclusion, the participation of local people in development activities and in the conservation and management of natural resources seems to be currently at the stage of passive or, at best, consultative participation. In order to deal with the severely increasing water problems in northern Thailand, decision-makers have to recognize the value of participation and promote a change of government officers’ attitude towards local people through training programs and incentives. Communities and individuals need to be made aware of their constitutional rights and potentials for cooperating with government agencies and participating in their projects.
CH₄ decompostion kinetics on supported Co and Ni catalysts
Creators: name: Zhang, Yi
Publisher: name: University of British Columbia
Year: 2009

description: Methane activation is important in a number of reactions that aim to convert natural gas to more valuable products using supported metal catalysts. As a potential alternative to steam reforming and partial oxidation, catalytic decomposition of CH4 may provide H2 without CO contamination for use with PEM fuel cells. However, the mechanism of carbon deposition and catalyst deactivation during CH4 decomposition is complex and not fully understood. The present work is aimed at clarifying some aspects of catalyst deactivation during the decomposition of CH4 at moderate temperatures on low loading Co and Ni catalysts. The experimental observations presented in the present work suggest that catalyst deactivation was a consequence of the competition between the rate of encapsulating carbon formation and the rate of carbon diffusion. Stable activity or catalyst deactivation during CH4 decomposition was observed, depending on which of these two rates was greater. The experimental observations also show that the gas phase composition KM , and catalyst properties such as metal particle size and metal-support interaction have a critical effect on catalyst deactivation: catalyst deactivation was reduced with increasing KM and with increasing metal particle size; catalyst deactivation was increased by a strong metal-support interaction. A general kinetic model of CH4 decomposition on supported metal catalysts has been developed based on experimental observations and the deactivation mechanism described above. The initial rate increase was described by including the rate of carbon nucleation at the tailing face of the metal particle using two methods: Cluster nucleation (Kinetic Model I) and Boltzmann nucleation (Kinetic Model II). The fit of literature data to Kinetic Model I and Kinetic Model II confirmed the presence of carbon nucleation at the tailing face. The observed CH4 decomposition activity profiles on supported Co catalysts with either stable activity or declining activity were well described by the kinetic model. The site density profile along the metal particle was obtained and the effect of metal particle size on the CH4 decomposition activity has been quantified by fitting the observed CH4 decomposition activity profiles to the developed kinetic model.

description: The temperature, doping and field dependences of the magnetoresistance (MR) in Pr_(2-x)Ce_(x)CuO_(4-delta) films are reported. We distinguish between orbital MR, found when the magnetic field is applied perpendicular to the ab planes, and the nearly isotropic spin MR. The latter, the major MR effect in the superconducting samples, appears in the region of the doping-temperature phase diagram where d(rho)/dT<0, or an upturn in the resistivity appears. We conclude that the upturn originates from spin scattering processes.

description: There is a common belief in the condensed matter community that bulk quantities become insensitive to the boundary condition in the infinite-volume limit. Here we reconsider this statement in terms of recent arguments of non-Hermitian skin effects, -strong dependence of spectra on boundary conditions for the non-Hermitian Hamiltonians-, in the traditional Green's function formalism. We find the criterion for quantities to be sensitive/insensitive against the boundary condition in Hermitian correlated/disordered systems, which is characterized by the residue theorem. We also discuss the uncertainty of the quasiparticle energy under the skin effects in terms of nonnormal pseudospectra, which can be tested via the sharp optical absorption from the bulk-surface coupling. Our result indicates that "pseudo quantum number" emerges as a consequence of large nonnormality.

description: Because the conditions for agricultural development vary considerably across space, we need to develop methods that allow us to take such variability into account when evaluating development strategies for particular crops or farming systems. This paper addresses spatially varying characteristics in an evaluation of the potential economic benefits of three cotton development strategies for Uganda: area expansion, productivity improvement, and domestic consumption increase. We begin with a historical review of cotton production in Uganda. We then described the major challenges and opportunities for Ugandan cotton production, including farm-level production constraints. Household-level production data from the 2000 Uganda National Household Survey (UNHS) are used to estimate the current spatial distribution of cotton production (called the cotton production area, or CPA), based on the association of household cotton production with ranges in mapped variables (altitude, length of growing period, and population density), district cotton production statistics and expert knowledge of local production patterns. Cotton development domains (CDDs) are then defined by agroclimatic suitability, market/ginnery access, and inclusion in the CPA. We use the UNHS data to evaluate the importance of cotton as a livelihood enterprise and its role in rural livelihood strategies. Key ecosystems and protected areas are considered in conjunction with the CDDs in defining feasible areas for expansion of production. Finally, the Dynamic Research Evaluation for Management (DREAM) model is used to estimate benefits that accrue from the three development strategies considered.

description: The aim of this paper is to analyze the technological management in a dairy industry, making it possible to suggest improvements. An open-ended questionnaire was applied, considering two main points: the classification and comprehension of the company’s performance in relation to the technologies available and the understanding of the industry’s technological motivations, making it possible to analyze technological behaviors, forms of acquisition and adoption of technological innovations. It was observed that the company loses competitiveness due to the technology adopted, when compared to bigger players and when the distribution of its products is carried out through supermarkets. The changes introduced in the products’ portfolio were of public-domain, stable and highly divulged, in other words, they were not a technological barrier to the industry’s competitors. The industry established a technological partnership with research institutes for treating the industrial effluents and also with another dairy industry, fortifying its financial, production and marketing areas. It was concluded that improvements in the production process, to reduce costs and better meet the consumers’ needs, are still necessary. The technological partnerships are an important part of this process.

description: HD110432 has gained considerable attention because it is a hard, variable X-ray source similar to gamma Cas. From time-serial echelle data obtained over two weeks during 2005 January and February, we find several remarkable characteristics in the star's optical spectrum. The line profiles show rapid variations on some nights which can be most likely be attributed to irregularly occurring and short-lived migrating subfeatures. Such features have only been observed to date in gamma Cas and AB Dor, two stars for which it is believed magnetic fields force circumstellar clouds to corotate over the stellar surface. The star's optical spectrum also exhibits a number of mainly FeII and HeI emission features with profiles typical of an optically thin disk viewed edge-on. Using spectral synthesis techniques, we find that its temperature is 9800K +/-300K, that its projected area is a remarkably large 100 stellar areas, and its emitting volume resides at a distance of 1 AU from the star. We also find that the star's absorption profiles extend to +/-1000 km/s, a fact which we cannot explain. Otherwise, HD110432 and gamma Cas share similarly peculiar X-ray and optical characteristics such as high X-ray temperature, erratic X-ray variability on timescales of a few hours, optical emission lines, and submigrating features in optical line profiles. Because of these similarities, we suggest that this star is a new member of a select class of "gamma Cas analogs."

Iron promoted activated alumina for scavenging free oxygen in claus converters
Creators: name: Bedrossian, Sevan
Publisher: name: University of British Columbia
Year: 2009

description: The Claus process is used to remove H2S from acid gas streams and is widely practiced in industry. The most common Claus catalyst in sulphur recovery units is activated alumina (γ- Al2O3). However, it is well documented that excessive free oxygen in the Claus process stream deactivates the alumina catalyst. O2 surface reactions with SO2 lead to sulphation of the alumina surface, thereby inhibiting the conversion of H2S and CS2. One approach to minimizing deactivation by sulphate formation is to use a dual bed reactor configuration, where part of the conventional alumina catalyst is replaced with a catalyst that will promote oxygen consumption and thereby limit sulphate formation. In the present study, Fe catalysts supported on alumina have been examined for oxygen removal. The catalysts were prepared by impregnating a commercial alumina support with solutions of Fe (NO3) 3.9H2O. Catalysts were characterized using XRD (X-ray Diffraction Spectroscopy) and DRIFT (Fourier Transmission Infrared Spectroscopy) as well as BET surface area measurement. The stable phase of Fe on the alumina in the relatively rich H2S reaction gas, typical of Claus process streams, was verified to be FeS2- The effect of catalyst pre-treatment conditions on oxygen removal kinetics is also reported. Experiments showed that O2 consumption occurred on Fe2O3 sites based on the reaction (a) and on FeS2 sites based on the sequential reaction (a) and (b). (a) [Chemical Equation] (b) S + 02 > SO2. It was also concluded that the FeS2/γ-Al2O3 catalyst is bifunctional due to activity of the alumina support towards the Claus reaction. Further study of the O2 removal kinetics was therefore conducted on bulk FeS2 without support. By assuming the stoichiometric order for reactants, the reaction rate constants on bulk FeS2 were determined using the HYSYS simulator and the rate of reaction (b) faster than reaction (a). Hence, FeS2 provides an overall faster rate of O2 consumption than Fe2O3. Also, a mechanism was postulated and the rate limiting steps that were consistent with the rate data were identified.

description: We introduce a novel data-driven approach aimed at designing high-quality shape deformations based on a coarse localized input signal. Unlike previous data-driven methods that require a global shape encoding, we observe that detail-preserving deformations can be estimated reliably without any global context in certain scenarios. Building on this intuition, we leverage Jacobians defined in a one-ring neighborhood as a coarse representation of the deformation. Using this as the input to our neural network, we apply a series of MLPs combined with feature smoothing to learn the Jacobian corresponding to the detail-preserving deformation, from which the embedding is recovered by the standard Poisson solve. Crucially, by removing the dependence on a global encoding, every \textit{point} becomes a training example, making the supervision particularly lightweight. Moreover, when trained on a class of shapes, our approach demonstrates remarkable generalization across different object categories. Equipped with this novel network, we explore three main tasks: refining an approximate shape correspondence, unsupervised deformation and mapping, and shape editing.

description: Emerging as a promising pathway to HIV vaccines, Virus-Like Particles (VLPs) have drawn considerable attention in recent years. A challenge of working with HIV VLPs in biopharmaceutical processes is their low rigidity, and factors such as shear stress, osmotic pressure and pH variation have to be reduced during their production. In this context, the purification and concentration of VLPs are often achieved by means of Tangential Flow Filtration (TFF) involving ultrafiltration hollow fiber modules. Despite the urgent need for robust upscaling strategies and further process cost reduction, very little attention has been dedicated to the identification of the mechanisms limiting the performance of HIV VLP TFF processes. In this work, for the first time, a hydrodynamic approach based on particle friction was successfully developed as a methodology for both the optimization and the upscaling of HIV VLP TFF. Friction forces acting on near-membrane HIV VLPs are estimated, and the plausibility of the derived static coefficients of friction is discussed. The particle friction-based model seems to be very suitable for the fitting of experimental data related to HIV VLP TFF as well as for upscaling projections. According to our predictions, there is still considerable room for improvement of HIV VLP TFF, and operating this process at slightly higher flow velocities may dramatically enhance the efficiency of VLP purification and concentration. This work offers substantial guidance to membrane scientists during the design of upscaling strategies for HIV VLP TFF.
title: Innate adaptation: the influence of human cytomegalovirus on natural killer cells
Creators: name: Holder, L. Kayla A.
Publisher: name: Memorial University of Newfoundland
Year: 2021

description: During their lifetime, over half the world’s population will experience chronic viral infection or cancer, both of which involve evasion of host immunity. We have within us immune cells called natural killer (NK) cells that constantly survey our tissues to detect and eliminate transformed and infected cells. Thus, they have a critical role in preventing cancer and containing virus infection. Although most viruses only disrupt our lives transiently, if at all, some viruses establish life-long persistent infection. Human cytomegalovirus (HCMV) is a common herpesvirus infecting most of the adult population and although relatively innocuous in healthy individuals, HCMV infection or reactivation has an enormous impact on the human immune system, poses serious health risks to the immunocompromised, and is an important cofactor driving ongoing immune activation in people living with HIV (PLWH). One outcome of HCMV infection is emergence of a stable differentiated population of phenotypically and functionally adapted NK cells exhibiting a form of memory. While mechanisms that create adapted NK cells in vivo remain enigmatic, exposure to HCMV is the one common factor underlying their presence. Exploring basic molecular mechanisms governing NK cell-mediated immunity can inform cell-based treatment strategies against virus infection or cancer. As chronic HIV-1 infection amplifies HCMV-driven accumulation of adaptive NK cells, we studied whether NK cell adaptation to HCMV infection functionally impacts their natural and antibody-dependent cytotoxic functions in this setting. Although factors present during HCMV infection augmented NK cell activity, we found no evidence that NK cells acquire superior cytotoxic function or capacity for interferon-γ secretion in response to target cells following adaptation to HCMV infection. However, HCMV-driven NK cell adaptation in HIV-1 infection paralleled increased expression of TIGIT, an inhibitory immune checkpoint receptor, on NK cells. As chronic virus infection contributes to effector cell dysfunction, punctuated by increased expression of inhibitory immune checkpoint receptors, it is important to unravel the mechanisms by which viruses affect regular NK cell functions to either prevent dysfunction or introduce disease-appropriate mediators to invigorate NK cell responses. Understanding basic molecular mechanisms governing NK cell-mediated immunity will inform new strategies to optimize our immune system capacities.

description: In this paper we describe the group of symmetries of a two-dimensional continued fraction. As a multidimensional generalization of continued fractions we consider Klein polyhedra. We distinguish two types of symmetries: the Dirichlet-type ones, that correspond to the multiplication by units of the corresponding number field, and so called palindromic ones. The main result of the paper is a criterion for a two-dimensional continued fraction to have a palindromic symmetry. This criterion is analogous to the criterion for the period of a quadratic irrationality to be symmetric.

description: Cerium-based intermetallics are currently attracting much interest as a possible alternative to existing high-performance magnets containing scarce heavy rare-earth elements. However, the intrinsic magnetic properties of Ce in these systems are poorly understood due to the difficulty of a quantitative description of the Kondo effect, a many-body phenomenon where conduction electrons screen out the Ce-4f moment. Here, we show that the Ce-4f shell in Ce-Fe intermetallics is partially Kondo screened. The Kondo scale is dramatically enhanced by nitrogen interstitials completely suppressing the Ce-4f contribution to the magnetic anisotropy, in striking contrast to the effect of nitrogenation in isostructural intermetallics containing other rare-earth elements. We determine the full temperature dependence of the Ce-4f single-ion anisotropy and show that even unscreened Ce-4f moments contribute little to the room-temperature intrinsic magnetic hardness. Our study thus establishes fundamental constraints on the potential of cerium-based permanent magnet intermetallics.
Are Horticultural Exports a Replicable Success Story? Evidence from Kenya and Côte d'Ivoire

description: Kenyan horticultural exports are often cited as a success story in African agriculture. Fruit and vegetable exports from Côte d’Ivoire have received less attention, but the export value is similar to that of Kenya. This paper focuses on three questions. First, do the horticultural sectors of Kenya and Côte d’Ivoire constitute valid success stories? Second, what factors have contributed to the success (or lack thereof)? And third, to what degree can the success be replicated in other African countries? The paper finds that Kenyan horticultural exports are indeed a success story: horticulture has become the third largest earner of foreign exchange, more than half the exports are produced by smallholders, and smallholders gain from producing for the export market. At the same time, the total number of smallholders producing for export is relatively small, and trends in European retailing may shift the advantage to larger producers. Côte d’Ivoire is not as clearly a success story because the most of the exports are produced on large industrial estates and because growth has been uneven. Ivorian exports rely on preferential access to European markets relative to Latin American exporters, raising doubts about sustainability. Factors in the growth and success of horticultural exports include a realistic exchange rate, stable policies, a good investment climate, competitive international transport connections, institutional, and social links with markets in Europe, and continual experimentation with the market institutions to link farmers and exporters. Smallholder participation is encouraged by farmer training and extension schemes, investment in small-scale irrigation, and assistance in establishing links with exporters. Many of the lessons of Kenyan horticulture can be applied elsewhere in Africa. Indeed, Kenya faces increasing competition from neighboring countries trying to replicate its success. At the same time, market institutions take time to develop, and demand constraints probably prevent other African countries from achieving the same level of success as Kenya.
ZZ brane amplitudes from matrix models

description: We study instanton contribution to the partition function of the one matrix model in the k-th multicritical region, which corresponds to the (2,2k-1) minimal model coupled to Liouville theory. The instantons in the one matrix model are given by local extrema of the effective potential for a matrix eigenvalue and identified with the ZZ branes in Liouville theory. We show that the 2-instanton contribution in the partition function is universal as well as the 1-instanton contribution and that the connected part of the 2-instanton contribution reproduces the annulus amplitudes between the ZZ branes in Liouville theory. Our result serves as another nontrivial check on the correspondence between the instantons in the one matrix model and the ZZ branes in Liouville theory, and also suggests that the expansion of the partition function in terms of the instanton numbers are universal and gives systematically ZZ brane amplitudes in Liouville theory.

description: Current dual-frequency magneto-optical traps (MOTs) for ultracold molecules are plagued by sub-Doppler heating effects, making them vastly inferior to standard atomic MOTs. Here we demonstrate theoretically that the sub-Doppler effects in such a MOT can be engineered to provide cooling instead of heating. We give an intuitive picture how to achieve such cooling and show the cooling and trapping force results of the 16-level optical Bloch equations for the case of CaF molecules. From three-dimensional Monte Carlo simulations we estimate the temperature and density of our MOT to be 40μK and 4×108cm-3, respectively, for a molecule number of 1×105. We also extend our idea to the case of atomic MOTs and show that it can be used to produce sub-Doppler forces in these systems that are much more robust against magnetic fields.
Ultraviolet Extinction Properties in the Milky Way

description: We have assembled a homogeneous database of 417 ultraviolet (UV) extinction curves for reddened sightlines having International Ultraviolet Explorer (IUE) spectra. We have combined these with optical and 2MASS photometry allowing estimates of the ratio of total-to-selective extinction, R(V), for the entire sample. Fitzpatrick-Massa (FM) parameters have also been found for the entire sample. This is the largest study of parameterized UV extinction curves yet published and it covers a wide range of environments, from dense molecular clouds to the diffuse interstellar medium (ISM), with extinctions A(V) ranging from 0.50 to 4.80. It is the first to extend far beyond the solar neighborhood and into the Galaxy at large, with 30 sightlines having distances > 5 kpc. Previously, the longest sightlines with FM parameters and R(V) extended ~ 1 kpc. We find that (1.) the CCM extinction law applies for 93% of the sightlines, implying that dust processing in the Galaxy is efficient and systematic; (2.) the central wavelength of the 2175 A bump is constant; (3.) the 2175 A bump width is dependent on environment. Only four sightlines show systematic deviations from CCM, HD 29647, 62542, 204827, and 210121. These sightlines all sample dense, molecule-rich clouds. The new extinction curves and values of R(V) allow us to revise the CCM law.

description: In the field of telecommunications and cloud communications, accurately and in real-time detecting whether a human or an answering machine has answered an outbound call is of paramount importance. This problem is of particular significance during campaigns as it enhances service quality, efficiency and cost reduction through precise caller identification. Despite the significance of the field, it remains inadequately explored in the existing literature. This paper presents an innovative approach to answering machine detection that leverages transfer learning through the YAMNet model for feature extraction. The YAMNet architecture facilitates the training of a recurrent-based classifier, enabling real-time processing of audio streams, as opposed to fixed-length recordings. The results demonstrate an accuracy of over 96% on the test set. Furthermore, we conduct an in-depth analysis of misclassified samples and reveal that an accuracy exceeding 98% can be achieved with the integration of a silence detection algorithm, such as the one provided by FFmpeg.

description: In a recent comment to the paper Chaotic Integrable transition in the SYK model, it was claimed that, in a certain region of parameters, the Lyapunov exponent of the N Majoranas Sachdev-Ye-Kitaev model with a quadratic perturbation, is always positive. This implies that the model is quantum chaotic. In this reply, we show that the employed perturbative formalism breaks down precisely in the range of parameters investigated in the comment due to a lack of separation of time scales. Moreover, based on recent analytical results, we show that for any large and fixed N, the model has indeed a chaotic-integrable transition that invalidate the results of the comment.
