Publisher: name: Zenodo
Year: 2023

description: Although several studies have been carried out about the complexity of the physical, chemical, mineralogical, petrographic and biological aspects of the deterioration of stone materials, at present there is no definitive achievement on the understanding and quantification of climate change effects on stone surface recession. HYPERION results are filling this gap, by improving our knowledge on measurable parameters influencing deterioration rate, especially those related to the environment (e.g., temperature, relative humidity, precipitation amount, pollutant agents, etc.). Inadequacy of existent dose-response deterioration equations strongly limit the applicability to real specific situations. Therefore, a deeper knowledge of surface recession related to the petrographic features of stones is fundamental to define new reliable dose-response functions. Laboratory tests, in controlled conditions and reproducing different environmental conditions (in particular, using different rainwater compositions, which strongly affect the damage of carbonate rocks), allow quantifying the surface recession rate phenomena and the prediction of future scenarios. The optimisation of dose-response functions can actually be a significant tool for mitigating climate change effects on cultural heritage. In order to reach this goal, this Deliverable (D4.5) aims to measure the recession rate of eleven carbonate rocks widely used in the cultural heritage of Italy. This increases the number of stone types adopted in the HYPERION project, in order to cover the largest range of types of limestones (e.g. different in grain size, composition, porosity) and to obtain the largest case study to be applied in different contexts. These stones were subjected to accelerated ageing tests in an environmental test chamber for simulating the wetting effect of rainwater, using two different water compositions corresponding to two different rainwaters (with pH≈6 and pH≈7). Bulk stone recession is evaluated considering sample weight loss as a function of the number of wetting cycles. Moreover, direct measurements of recession are performed by Confocal Microscopy (CM), which allowed 3D reconstruction of the stone surface and evaluation of differential recession as a function of calcite grain size.
title: Teaching in Multicultural Societies: the theories and practice of teachers in Greek Community Schools
Creators: name: Pantazi, Efstathia
Publisher: name: Goldsmiths, University of London
Year: 2006

description: The study focuses on teachers funded by the Greek state to come to the UK and work in Greek Community Schools. It explores their theories and practices as they develop through the experience of working with minority groups, and as they shift in position from Greece to the UK The study is rooted in the assumption that teachers are professionals who reflect on their experiences (often critically) and, as they have to 'translate' policy into workable practice, are in a unique position to contribute to educational research and the policy process. The research 'gives voice' to the teachers, potentially contributing to the policy agenda both in Greece (in the context of its recent attempts to make education more multicultural through an 'Interculturalist' education policy), and in the Community Schools in the UK The research focuses on three sets of questions: those connected with language; questions relating to issues of culture and identity; and questions related to teachers' reflective practice. The processes and conditions which support reflection and critique are explored, for example the role of 'critical incidents' in destabilising preconceptions and assumptions. The study explores and attempts to connect discourses on multiculturalism with discourses on the role of the teacher, through positioning the teacher at the centre of the discourse. The findings indicate that as the teachers become more reflective, their theories become at once more grounded and more critical. Thus a shift takes place towards discourses supporting additive forms of bilingualism, supporting strong critical forms of multiculturalism - and opposing powerful assimilationist discourses. At the same time the 'model' of the teacher revealed in their discourse shifts: from 'deliverer' to active contributor, capable of contributing to the policy process. In sum, the teachers' knowledge of different models of managing multicultural reality represents unique value as feedback to both the Community Schools and the mainstream in Greece.

description: In the present study, we propose a new perspective on thermal dissipation based on the thermo field dynamics. From the view point of the renormalization theory, there appear effective interactions between the original and tilde spaces on thermo field dynamics with reducing thermal disturbances. This study yields the equivalence of the following two pictures, namely such a spin system with a random field due to a heat bath as is defined in a Hilbert space and a finite-size system with effective interactions defined in a double Hilbert space. The correspondence of the above two systems yields such perspective that the thermal disturbance is described by the effective non-Hermitian interactions.

description: Ferroelasticity describes a phenomenon in which a material exhibits two or more equally stable orientation variants and can be switched from one form to another under an applied stress. Recent works have demonstrated that two-dimensional layered organic$-$inorganic hybrid Ruddlesden$-$Popper perovskites can serve as ideal platforms for realizing ferroelasticity, however, the ferroelastic (FE) behavior of structures with a single octahedra layer such as (BA)$_2$PbI$_4$ (BA = CH$_3$(CH$_2$)$_3$NH$_3$$^+$) has remained elusive. Herein, by using a combined first-principles and metadynamics approach, the FE behavior of (BA)$_2$PbI$_4$ under mechanical and thermal stresses is uncovered. FE switching is mediated by cross-plane intermolecular coupling, which could occur through multiple rotational modes, rendering the formation of FE domains and several metastable paraelastic (PE) phases. Such metastable phases are akin to wrinkled structures in other layered materials and can act as a "funnel" of hole carriers. Thermal excitation tends to flatten the kinetic barriers of the transition pathways between orientation variants, suggesting an enhanced concentration of metastable PE states at high temperatures, while halogen mixing with Br raises these barriers and conversely lowers the concentration of PE states. These findings reveal the rich structural diversity of (BA)$_2$PbI$_4$ domains, which can play a vital role in enhancing the optoelectronic properties of the perovskite and raise exciting prospects for mechanical switching, shape memory, and information processing.

description: Mothers, infants, and children under five in Cleveland County, North Carolina (priority population) have limited access to healthy foods due to the neighborhood and built environment consisting of a lack of public transportation, a rural geography, and a scarcity of grocery stores that offer a wide selection of healthy foods, including fresh fruits and vegetables. An unhealthy diet lacking in fresh fruits and vegetables can increase the risk of poor health consequences including decreased immunity, poor maternal health and/or fetal outcomes, obesity, and diabetes. We will implement a mobile market stocked with healthy foods including fresh fruits and vegetables, serving rural areas of the county, accepting WIC, SNAP, or cash/credit payments. To evaluate the program's outcomes, a study will be conducted to assess participants' fruit and vegetable intakes, pre- and post-intervention. This program strives to improve access to healthy food and increase the priority population’s overall fruit and vegetable intake.

description: We present a study of 33 {\it Kepler} planet-candidate host stars for which asteroseismic observations have sufficiently high signal-to-noise ratio to allow extraction of individual pulsation frequencies. We implement a new Bayesian scheme that is flexible in its input to process individual oscillation frequencies, combinations of them, and average asteroseismic parameters, and derive robust fundamental properties for these targets. Applying this scheme to grids of evolutionary models yields stellar properties with median statistical uncertainties of 1.2\% (radius), 1.7\% (density), 3.3\% (mass), 4.4\% (distance), and 14\% (age), making this the exoplanet host-star sample with the most precise and uniformly determined fundamental parameters to date. We assess the systematics from changes in the solar abundances and mixing-length parameter, showing that they are smaller than the statistical errors. We also determine the stellar properties with three other fitting algorithms and explore the systematics arising from using different evolution and pulsation codes, resulting in 1\% in density and radius, and 2\% and 7\% in mass and age, respectively. We confirm previous findings of the initial helium abundance being a source of systematics comparable to our statistical uncertainties, and discuss future prospects for constraining this parameter by combining asteroseismology and data from space missions. Finally we compare our derived properties with those obtained using the global average asteroseismic observables along with effective temperature and metallicity, finding an excellent level of agreement. Owing to selection effects, our results show that the majority of the high signal-to-noise ratio asteroseismic {\it Kepler} host stars are older than the Sun.

description: We report a layered transition-metal-ordered oxypnictide Sr$_{2}$CrCoAsO$_{3}$. The new material was synthesized by solid-state reactions under vacuum. It has an intergrowth structure with a perovskite-like Sr$_3$Cr$_2$O$_6$ unit and ThCr$_2$Si$_2$-type SrCo$_2$As$_2$ block stacking coherently along the crystallographic $c$ axis. The measurements of electrical resistivity, magnetic susceptibility, and specific heat indicate metallic conductivity from the CoAs layers and short-range antiferromagnetic ordering in the CrO$_{2}$ planes. No itinerant-electron ferromagnetism expected in CoAs layers is observed. This result, combined with the first-principles calculations and the previous reports of other CoAs-layer-based materials, suggests that the Co$-$Co bondlength plays a crucial role in the emergence of itinerant ferromagnetism.

description: Education Access and Quality influences health over the lifespan. Affordable access to quality education or lack thereof can lead to low educational attainment, low-wage employment, and overall poor health. This proposal describes a free Universal Breakfast After the Bell(UBAB) program, an evidence-based program proven to increase participation in school breakfast programs and shown in research to increase access to nutritious food equitably. Evidence shows that habitual consumption of breakfast leads to increased attendance, academic performance, and increased graduation rates. The goal of the program is to provide Cleveland County High School students the nutritional support needed to improve academic attainment and increase high school graduation rates.
title: The effect of personality on attentional strategy in category learning
Creators: name: Tharp, Ian James
Publisher: name: Goldsmiths, University of London
Year: 2007

description: his thesis explores the mediating effects of personality on attention and performance during the learning of novel categories. Major theories of category learning emphasise the role of dopamine on a variety of processes engaged during such learning. Two core personality domains, namely extraversion and a cluster of traits collectively termed impulsive, anti-social, sensation seeking (ImpASS), were considered. These personality traits were of interest because it has been suggested that their biological basis may partly reflect variation in dopaminergic neurotransmission. Schizotypal personality, owing to its association with schizophrenia, may also reflect dopaminergic function and was also considered. A series of behavioural experiments were undertaken to examine the relationship between these key personality constructs and the learning of new stimulus-category associations. In particular the manner in which the properties (e.g., size, shape, colour etc) of the stimuli were utilised during the learning of the category labels was considered. Various studies allowed assessment of both accuracy performance and attentional strategy. The first study involved the comparison of performance on two distinct tasks, with identical stimuli and responses. The category structure was manipulated such that the rule for one task was simple and verbalisable, whereas the rule for the other was more complex and not easily verbalisable. A subsequent study explored the ability to adapt a reasonably accurate simple response strategy to a more complex, yet more appropriate (and beneficial) strategy. Eye-tracking methods were employed, in further similar studies, to measure the 'attention' given to different stimulus features. Reaction time methodology was used in another study to explore the degree of incidental learning about nominally task irrelevant stimulus information, during a simple classification task. Extraversion and ImpASS often appeared differentially associated with categorisation performance and strategy use. The latter trait was associated with a preference for simplistic or more salient category rules and, in contrast to extraversion, was associated with less flexible modification of response strategy. The results presented also emphasized the important role of attentional processes during category learning. For example, positive schizotypy was associated with decreased processing of nominally irrelevant stimulus features during speeded categorisation. The implications of the results for future work, and for theories of the personality constructs investigated, were also considered.

description: Since the launch of Blue-Cloud, the project has proactively worked on establishing strong partnerships between a variety of actors, aiming to create long-lasting relationships both for attaining the Blue-Cloud's long-term objectives and for contributing to shaping the strategic Roadmap to 2030. Blue-Cloud has established synergies in the Open Science, Blue Economy and Marine Research fields as the team believes that through collaboration and cooperation with initiatives operating in the same field, the value of Blue Cloud services increases. As output of this effort to cluster with related projects and initiatives in Europe and Beyond, this first release of the Blue-Cloud Factsheets for cluster projects and other core initiatives presents an overview of all the projects and infrastructures Blue-Cloud has established synergies with in the first year and a half from its launch (M18). The collaborations span from data integration to joint communication events. Overall, the synergies established have been classified around the main assets of the Blue-Cloud infrastructure: Data Discovery and Access Service, Cyber Infrastructure and Virtual Research Environment, and Demonstrators, plus a categories for those initiatives looking forward to contribute to the BlueCloud Roadmap. So far Blue-Cloud has established connections with 32 projects and organisations and has started concrete collaboration with 21, greatly surpassing the KPI for M36 (10). The dialogues represent the ground layer for successful collaborations to be pursued in the next months, leveraging on the public availability of the Bluer-Cloud resources, namely the demonstrators and their VREs (launched for public use in March 2021), the Blue-Cloud Discovery and Access services (to be ready in May 2021) and last but not least the unprecedented wealth of data resources of Blue-Cloud. This document represents a first release of the Blue-Cloud fact sheets for cluster projects and other core initiatives. * Section 1 presents the approach adopted and an overview of the synergies established in the framework of Blue-Cloud main assets. * Section 2 lists the Factsheets for cluster projects and other initiatives, grouped by e-Infrastructures (2.1), Blue Data infrastructures (2.2) and other projects and initiatives (2.3). A second release of this report (D6.6) will be produced at the end of the project (M35).

description: The world is dominated by the unsustainable model of the linear economy. Our society, the education system even sustainability education is based on take-make-dispose practices. A paradigm shift is required in education to overcome the impacts of almost a century of domination and transition to a circular model. This paper presents a graduate product design course that focuses on closed-loop systems and ways of regenerating value through repairing rather than making something new. Actual Repair is a graduate course, within a trans-disciplinary international MSc program, with a unique triple task approach. For the first task students were expected to find a (set of) broken/damaged product(s), and visibly repair it/them in an aesthetically pleasing way. Then, they organised a Repair Café as a group for the second task. Finally, the third task required designing a system or the touchpoints of a system in which products are repaired. This triple task process resulted in a multifaceted learning experience. At several points during the course, reflective sessions were held to help students articulate the higher-level learnings from their separate projects. Resulting from this research, learning perspectives including circular thinking perspective, seeing the repair possibilities, the stigma of repair, interest in the circular economy, understanding limited resources, exploring community value and exploring alternative user perspectives were presented. This paper contributes to the existing literature by providing a case of incorporating repair into product design education, and by exploring how doing so through three different perspectives triggers deeper learning than a single perspective would have.

description: This paper aims to outline the problems presented by transportation barriers throughout Cleveland County, North Carolina, while also providing program and policy solutions to increase access to vital healthcare services, nutrition resources, and other county services. Cleveland County is a geographically diverse county lacking formal public transportation, leaving vulnerable populations at risk for limited healthcare access, food insecurity, and other communication barriers. Older adults living in the most rural parts of the county face the greatest risks associated with transportation barriers and serve as a priority population when developing program interventions. A thorough policy analysis highlighted county-wide broadband access as the best solution to increasing connection to vital community resources, namely telehealth and nutrition resources.  Furthermore, when addressing food insecurity throughout Cleveland County, mobile food pantries will allow for food delivery to individuals most isolated by transportation barriers.

description: This paper explores user perspectives about product repair to prolong the useful lives of products towards the circular economy. Product longevity can effectively be achieved by repair and reuse, where no virgin materials are required. However, the decision of whether or not to repair something is initiated by the users. Their motivations and choices are vital to postpone product replacement. Therefore, users’ motivations and barriers related to product repair were explored in this research with cultural probes, research through design and phenomenology methods. Fogg’s Behaviour Model was utilised to get a deeper understanding of the subject. The results were further developed and tested through the workshops with users. New repair methods and examples were created and used to inspire participants to reflect their experiences about repaired and broken products. The findings from this study suggest that repair decision is affected by a multitude of sociological and psychological motivators and barriers including reversibility, endurance, aesthetics and storytelling. This study contributes to the literature through the development of the fifteen design considerations which comprise categories of motivations and barriers that users experience about repair. They suggest opportunities to understand and change user behaviour, through design, to reduce their environmental impact. Overall, the results call into question the prevalent picture of business-focused circular economy literature. Furthermore, it is discussed that users' participation is the key to unleash the potential power of the inner circles.

description: Ionic liquids have been suggested as new engineering fluids, namely in the area of heat transfer, as alternatives to current biphenyl and diphenyl oxide, alkylated aromatics and dimethyl polysiloxane oils, which degrade above 200 °C and pose some environmental problems. Recently, we have proposed 1-ethyl-3-methylimidazolium methanesulfonate, [$C_{2}mim$][$CH_{3}SO_{3}$], as a new heat transfer fluid, because of its thermophysical and toxicological properties. However, there are some interesting points raised in this work, namely the possibility of the existence of liquid metastability below the melting point (303 K) or second order-disorder transitions ($λ$-type) before reaching the calorimetric freezing point. This paper analyses in more detail this zone of the phase diagram of the pure fluid, by reporting accurate thermal-conductivity measurements between 278 and 355 K with an estimated uncertainty of 2% at a 95% confidence level. A new value of the melting temperature is also reported, $T_{melt}$ = 307.8 $\pm$ 1 K. Results obtained support liquid metastability behaviour in the solid-phase region and permit the use of this ionic liquid at a heat transfer fluid at temperatures below its melting point. Thermal conductivity models based on Bridgman theory and estimation formulas were also used in this work, failing to predict the experimental data within its uncertainty.

description: The CH$_3$(CH$_2$)$_u$COO(CH$_3$)$_v$CH$_3$ + n-alkane mixtures have been investigated on the basis of an experimental database containing effective dipole moments of esters, and excess molar functions of the systems: enthalpies ($H_{\text{m}}^{\text{E}}$), volumes ($V_{\text{m}}^{\text{E}}$), isobaric heat capacities ($C_{p\text{m}}^{\text{E}}$) and isochoric internal energies ($U_{V\text{m}}^{\text{E}}$) and by means of the application of the Flory model and the Kirkwood-Buff formalism. The situation of the mixtures within the $G_{\text{m}}^{\text{E}}$ (excess molar Gibbs energy) vs. $H_{\text{m}}^{\text{E}}$ diagram has also been briefly considered. Results indicate that dispersive interactions are dominant and that steric effects can explain some differences between solutions containing heptane and isomeric esters. Proximity and orientational effects are also discussed in diester + hexane mixtures. In the case of systems with a given alkane and different isomeric polar compounds, orientational effects become weaker in the order: n-alkanone > dialkyl carbonate > n-alkanoate. Results from the Kirkwood-Buff formalism indicate that the number of ester-ester interactions decreases in systems with alkyl ethanoates when the alkyl size increases and that preferential solvation between polar molecules decreases as follows: dialkyl carbonate > n-alkanone > n-alkanoate.

Its maximal group of invariance, which we call the SN group, is determined as the group of conformal Bargmann automorphisms that preserve the coupled Schrödinger and NC gravitational field equations. Canonical unitary representations of the SN group are worked out, helping us recover, in particular, a very specific occurrence of dilations with dynamical exponent $z=(\d+2)/3$.

description: Based on density functional calculations, we demonstrate a significant difference in oxidation patterns between graphene and graphite and the formation of defects after oxidation. Step-by-step modeling demonstrates that oxidation of 80% of the graphite surface is favorable. Oxidation above half of the graphite surface significantly decreases the energy costs of vacancy formation with CO2 production. The presence of water is crucial in the transformation of epoxy groups to hydroxyl, the intercalation with further bundle and exfoliation. In water-rich conditions, water intercalates graphite at the initial stages of oxidation and oxidation, which is similar to the oxidation process of free-standing graphene; in contrast, in water-free conditions, large molecules intercalate graphite only after oxidation occurs on more than half of the surface.

description: Mass distribution of black holes identified through X-ray emission suggests a paucity of black holes in the mass range of 3 to 5 solar masses. Modified theories have been devised to explain this mass gap, and it is suggested that natal kicks during supernova explosion can more easily disrupt binaries with lower mass black holes. Although recent LIGO observations reveal the existence of compact remnants within this mass gap, the question of whether low-mass black holes can exist in binaries remains a matter of debate. Such a system is expected to be noninteracting without X-ray emission, and can be searched for using radial velocity and astrometric methods. Here we report Gaia DR3 3425577610762832384, a wide binary system including a red giant star and an unseen object, exhibiting an orbital period of approximately 880 days and near-zero eccentricity. Through the combination of radial velocity measurements from LAMOST and astrometric data from Gaia DR2 and DR3 catalogs, we determine a mass of $3.6^{+0.8}_{-0.5}$ $M_{\odot}$ of the unseen component. This places the unseen companion within the mass gap, strongly suggesting the existence of binary systems containing low-mass black holes. More notably, the formation of its surprisingly wide circular orbit challenges current binary evolution and supernova explosion theories.

description: This paper aims to outline the problems presented by transportation barriers throughout Cleveland County, North Carolina, while also providing program and policy solutions to increase access to vital healthcare services, nutrition resources, and other county services. Cleveland County is a geographically diverse county lacking formal public transportation, leaving vulnerable populations at risk for limited healthcare access, food insecurity, and other communication barriers. Older adults living in the most rural parts of the county face the greatest risks associated with transportation barriers, and serve as a priority population when developing program interventions. A thorough policy analysis highlighted county-wide broadband access as the best solution to increasing connection to vital community resources, namely telehealth and nutrition resources.  Furthermore, when addressing food insecurity throughout Cleveland County, mobile food pantries will allow for food delivery to individuals most isolated by transportation barriers.

description: The form of the solar meridional circulation is a very important ingredient for mean field flux transport dynamo models. Yet a shroud of mystery still surrounds this large-scale flow, given that its measurement using current helioseismic techniques is challenging. In this work we use results from 3D global simulations of solar convection to infer the dynamical behavior of the established meridional circulation. We make a direct comparison between the meridional circulation that arises in these simulations and the latest observations. Based on our results we argue that there should be an equatorward flow at the base of the convection zone at mid latitudes, below the current maximum depth helioseismic measures can probe (0.75 R). We also provide physical arguments to justify this behaviour. The simulations indicate that the meridional circulation undergoes substantial changes in morphology as the magnetic cycle unfolds. We close by discussing the importance of these dynamical changes for current methods of observation that involve long averaging periods of helioseismic data. Also noteworthy is the fact that these topological changes indicate a rich interaction between magnetic fields and plasma flows, which challenges the ubiquitous kinematic approach used in the vast majority of mean field dynamo simulations.

description: Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) monoclonal antibodies (mAbs) are among the treatments recommended for high-risk ambulatory persons with coronavirus 2019 (COVID-19). Here, we study viral culture dynamics post-treatment in a subset of participants receiving the mAb bamlanivimab in the ACTIV-2 trial (ClinicalTrials.gov: NCT04518410). Viral load by qPCR and viral culture are performed from anterior nasal swabs collected on study days 0 (day of treatment), 1, 2, 3, and 7. Treatment with mAbs results in rapid clearance of culturable virus. One day after treatment, 0 of 28 (0%) participants receiving mAbs and 16 of 39 (41%) receiving placebo still have culturable virus (p < 0.0001). Recrudescence of culturable virus is detected in three participants with emerging mAb resistance and viral RNA rebound. While further studies are necessary to fully define the relationship between shed culturable virus and transmission, these results raise the possibility that mAbs may offer immediate (household) and public-health benefits by reducing onward transmission., Using longitudinal samples from the ACTIV-2 clinical trial of the monoclonal antibody bamlinivimab, Boucau et al. investigate the duration of shedding culturable virus. Treatment with monoclonal antibody results in rapid clearance of culturable virus. The emergence of mutations in a subset of participants coincides with viral rebound and resurgent culturable virus.

description: Использование вероятностных моделей на основе байесовских сетей является распространенным механизмом для описания процессов, протекающих в условиях неопределенности. Одним из актуальных направлений, связанных с оптимизацией расчета вероятностных характеристик динамических байесовских сетей, является оптимизация решения задач факторизации, распространения свидетельств и вычисления полного совместного распределения каждой из вершин графа байесовской сети. В исследовании рассматривается возможность представления байесовских сетей в виде гиперграфов. Исследование данного вопроса связано с необходимостью разработки оптимальных алгоритмов обучения байесовских сетей и определением основных подходов к реализации процедур опроса сети. Рассмотрены особенности использования вариационного вывода при формировании моделей перехода для нескольких смежных временных срезов с учетом семантики динамических байесовских сетей. Представлены алгоритмы для дискретных и непрерывных моделей динамических байесовских сетей. Предложенные подходы позволяют оптимизировать процедуру расчета априорных распределений динамической байесовской сети, упростить ее топологическую структуру, а так же оптимизировать процедуру опроса сети в момент получения новых свидетельств и определения распределения вероятностей для скрытых переменных с учетом данных свидетельств.
description: Probabilistic models based on Bayesian networks are used as a common mechanism to de-scribe processes occurring in uncertainty. The optimization of solving factorization problems, distributing evidence, and calculating the complete joint distribution of each vertices of the Bayesian network graph represents a current direction associated with optimizing the calculation of dynamic Bayesian networks’ variational features. The study considers the possibility of presenting Bayesian networks as hypergraphs resulting from the need to develop optimal learning algorithms of Bayesian networks and determine the main approaches to implementation of the network’s survey. Specifics of variational inference in forming transition models applied to certain adjacent time samplings are studied, with semantics of dynamic Bayesian networks considered. Algorithms for discrete and continuous models of dynamic Bayesian networks are presented. The proposed approaches make it possible to optimize the procedure for calculating a priori distributions of a dynamic Bayesian network, simplify its topological structure, as well as optimize the network’s survey when obtaining new
evidence and determining the probability distribution for hidden variables according to evidence data.
