title: An Investigation Into The Accessibility Of Massive Open Online Courses (MOOCs)
Creators: name: Iniesto, Francisco
Publisher: name: The Open University
Year: 2020

description: Massive Open Online Courses (MOOCs) are an evolution of open online learning that enables people to study online and for little or no cost. MOOCs can provide learners with the flexibility to learn, opportunities for social learning, and the chance to gain new skills and knowledge. While MOOCs have the potential to also bring these benefits to disabled learners, there is little understanding of how accessibility is embedded in the creation of MOOCs. The goal of this research has been to understand the accessibility barriers in MOOCs and to develop processes to identify and address those barriers. In the extant literature, the expectations of disabled learners when they take up MOOCs are not discussed and studies on MOOCs that report demographic data of learners do not consider disabled learners. However, disabled learners can face difficulties in accessing MOOCs, and certain learning designs of MOOCs may affect their engagement, causing them to miss out on opportunities offered by MOOCs. Technologies and the learning design approaches for MOOCs need to be as accessible as possible, so that learners can use MOOCs in a range of contexts, including via assistive technologies. This research has investigated the current state of accessibility in MOOCs. It has involved the following: Interviews with 26 MOOC providers; including software developers, accessibility managers, inclusion designers, instructional designers, course editors and learning media developers; Comparative quantitative survey data involving disabled and non-disabled learners participating in 14 MOOCs; Interviews with 15 disabled learners which have captured their experiences; and An accessibility audit was devised and then used to evaluate MOOCs from 4 major platforms: FutureLearn, edX, Coursera and Canvas. This audit comprises 4 components: technical accessibility, user experience (UX), quality and learning design; 10 experts were involved in its design and validation. This research programme has yielded an understanding of how MOOC providers cater for disabled learners, the motivations of disabled learners when taking part in MOOCs, and how MOOCs should be designed to be accessible for disabled learners. A range of barriers to accessibility in MOOCs have been identified, and an accessibility audit for MOOCs has been proposed. An open online learning environment should take into account learners’ abilities, learning goals, where learning takes place, and the different devices learners use. The research outcomes will be beneficial to MOOC providers to support the accessible design of MOOCs, including the educational resources and the platforms where the MOOCs are hosted. The ultimate beneficiaries of this research project are MOOC learners because accessible MOOCs will help support their lifelong learning and provide re-skilling opportunities.

description: In one dimensional wires, fluctuations destroy superconducting long-range order and stiffness at finite temperatures; in an infinite wire, quasi-long range order and stiffness survive at zero temperature if the wire's dimensionless admittance $μ$ is large, $μ> 2$. We analyze the disappearance of this superconductor-insulator quantum phase transition in a finite wire and its resurrection due to the wire's coupling to its environment characterized through the dimensionless conductance $K$. Integrating over phase slips, we determine the flow of couplings and establish the $μ$--$K$ phase diagram.

title: Cantor Bouquets and Wandering Domains for a Class of Entire Functions
Creators: name: Dourekas, Yannis
Publisher: name: The Open University
Year: 2020

description: In this thesis we focus on different topological structures that arise as a result of the iteration of functions in a class of sums of exponentials, along with the different Fatou components that exist for functions in this class, making particular reference to wandering domains. For many transcendental entire functions, the escaping set has the structure of a Cantor bouquet, consisting of uncountably many disjoint curves. Rippon and Stallard showed that there are many functions for which the escaping set has a new connected structure known as an infinite spider’s web. We investigate a connection between these two topological structures for functions in our class. The issue of whether an analytic function has wandering domains has long been of interest in complex dynamics. Sullivan proved in 1985 that rational maps do not have wandering domains. On the other hand, several transcendental entire functions have wandering domains. Using recent results on the relationship between Fatou components and the postsingular set, we prove that functions in a subset of our class do not have wandering domains. We also prove that for many of the functions the Julia set is the whole plane.

description: The temperature dependence of the electronic structure of CeBi arising from two types of antiferromagnetic transitions based on optical conductivity ($σ(ω)$) was observed. The $σ(ω)$ spectrum continuously and discontinuously changes at 25 and 11 K, respectively. Between these temperatures, two peaks in the spectrum rapidly shift to the opposite energy sides as the temperature changes. Through a comparison with the band calculation as well as with the theoretical $σ(ω)$ spectrum, this peak shift was explained by the energy shift of the Bi $6p$ band due to the mixing effect between the Ce $4f Γ_8$ and Bi $6p$ states. The single-layer antiferromagnetic ($+-$) transition from the paramagnetic state was concluded to be of the second order. The marked changes in the $σ(ω)$ spectrum at 11 K, however, indicated the change in the electronic structure was due to a first-order-like magnetic transition from a single-layer to a double-layer ($++--$) antiferromagnetic phase.

description: In this paper we will discuss the problem of trade’s impact on the environment, protection and threats to the cultural property. Man and all the other living beings are mutually related with the entire inanimate and living nature that surrounds them from the beginning of their existence. This interaction of man-living environment is the basis of the whole modern law of environmental protection. With each new discovery (starting with the tools needed for working the land and the invention of the wheel all the way to the modern computer technology) man fulfills an increasing part of the eternal desire to reconcile his needs and nature. In developing this work, we noticed the problem: “what is the impact that the trade has on the environment?“. Today, every citizen of the planet Earth is worried about environmental pollution because the consequences of it are seen daily, through the air we breathe, the water and the food that we consume and through pollution and radiation that we are exposed to, also the consequences of environmental problems are manifested through the shortage of natural resources, extinction of plant and animal species, and disturbance of the global ecosystem and biogeochemical processes.
Combining critical and quantum metrology

Year: 2023
Subjects: subject: Quantum Physics (quant-ph)

description: Critical metrology relies on the precise preparation of a system in its ground state near a quantum phase transition point where quantum correlations get very strong. Typically this increases the quantum Fisher information with respect to changes in system parameters and thus improves the optimally possible measurement precision limited by the Cramér-Rao bound. Hence critical metrology involves encoding information about the unknown parameter in changes of the system's ground state. Conversely, in conventional metrology methods like Ramsey interferometry, the eigenstates of the system remain unchanged, and information about the unknown parameter is encoded in the relative phases that excited system states accumulate during their time evolution. Here we introduce an approach combining these two methodologies into a unified protocol applicable to closed and driven-dissipative systems. We show that the quantum Fisher information in this case exhibits an additional interference term originating from the interplay between eigenstate and relative phase changes. We provide analytical expressions for the quantum and classical Fisher information in such a setup, elucidating as well a straightforward measurement approach that nearly attains the maximum precision permissible under the Cramér-Rao bound. We showcase these results by focusing on the squeezing Hamiltonian, which characterizes the thermodynamic limit of Dicke and Lipkin-Meshkov-Glick Hamiltonians.

description: The vision for the EU-Citizen.Science platform is to aid in the mainstreaming of citizen science, by building a sustainable platform as a learning space for citizen science in Europe for researchers, citizen science practitioners, policy makers, journalists, citizen scientists and other stakeholder groups. To achieve this aim, the project supports the development of ~20 training modules on a wide variety of CS-related subjects, aimed at this range of stakeholder groups. This Deliverable presents 24 training modules, 17 of which are from various Consortium partners and not the promised 3 but 10 modules developed by Cascading Grants awardees, drawing on the expertise from 10 institutions or individuals outside the Consortium. We describe the Moodle platform and the structure and topics of these training modules, the training and evaluation processes used in creating them, and the protocol created for future users of the eu-citizen.science platform who may choose to create their own training modules during the years 2022-2027. We also report how we built on our earlier work identifying specific training gaps in the field of CS, using a survey and a workshop to select the topics of the modules and widening the scope of topics and available languages with the call for Cascading Grants. Finally, this Deliverable concludes with somerecommendations for maintaining the sustainability of this platform, highlights potential topics for further training modules to be written in the future and provides some recommendations based on lessons learned for other CS Projects who may wish to provide CS training in the future.

description: In this work we study the radiative decays of heavy-light quarkonia through M1 and E1 transitions, that involve quark-triangle diagrams with two hadron vertices, and are difficult to evaluate in BSE-CIA. We have expressed the transition amplitude, $M_{fi}$ as a linear superposition of terms involving all possible combinations of $++$, and $--$ components of Salpeter wave functions of final and initial hadron, with coefficients being related to results of pole integrals over complex $σ$- plane. We evaluate the decay widths for $M1$ transitions ($^3S_1 \rightarrow ^1S_0 +γ$), and $E1$ transitions ($^3S_1 \rightarrow ^1P_0 +γ$ and $^1P_0 \rightarrow ^3S_1 +γ$). We have used algebraic forms of Salpeter wave functions obtained through analytic solutions of mass spectral equations for ground and excited states of $0^{++},1^{--}$, and $0^{-+}$ heavy-light quarkonia in approximate harmonic oscillator basis, to calculate their decay widths. The input parameters used by us were obtained by fitting to their mass spectra. We have compared our results with experimental data and other models, and found reasonable agreements.

description: There are reasons to believe that mechanisms exist in the solar interior which lead to random density perturbations in the resonant region of the Large Mixing Angle solution to the solar neutrino problem. We find that, in the presence of these density perturbations, the best fit point in the (sin^2(2θ), Delta_m^2) parameter space moves to smaller values, compared with the values obtained for the standard LMA solution. Combining solar data with KamLAND results, we find a new compatibility region, which we call VERY-LOW LMA, where sin^2(2θ) ~ 0.6 and Delta_m^2~2e-5 eV^2, for random density fluctuations of order 5% < ξ< 8%. We argue that such values of density fluctuations are still allowed by helioseismological observations at small scales of order 10 - 1000 km deep inside the solar core.

Interfacial and electronic dynamics of the aluminum-graphene interface structure were investigated using models of amorphous graphene added to an aluminum matrix. We examine the impact on electronic conduction caused by the presence of nitrogen impurities within the interfacial amorphous graphene layer. We elucidate the conduction mechanisms by using a projection of the conductivity into space.

description: D0-branes are unstable in the presence of an R-R field strength background. A fuzzy two-sphere is classically stable under such a background, this phenomenon being called the Myers effect. We analyze this effect from the viewpoint of tachyon condensation. It is explicitly shown that a fuzzy two-sphere is realized by the condensation of tachyons which appear from strings connecting different D0-branes. The formation of a fuzzy $CP^{2}$ is also investigated by considering the SU(3) invariant R-R field strength background. We find that the dynamics of the D-branes depends on the properties of the associated algebra.

description: In this work, we present a thorough analysis of $η_c(1S,2S)$ quarkonia hadroproduction in $k_\perp$-factorisation in the framework of the light-front potential approach for the quarkonium wave function. The off-shell matrix elements for the $g^* g^* η_c(1S,2S)$ vertices are derived. We discuss the importance of taking into account the gluon virtualities. %We discuss the role of relativistic corrections, the Melosh spin-rotation and theoretical uncertainties by comparing our results with the standard NRQCD approach. We present the transverse momentum distributions of $η_c$ for several models of the unintegrated gluon distributions. Our calculations are performed for four distinct parameterisations for the $c\bar c$ interaction potential consistent with the meson spectra. We compare our results for $η_c(1S)$ to measurements by the LHCb collaboration and present predictions for $η_c(2S)$ production.

description: People are becoming increasingly comfortable using Digital Assistants (DAs) to interact with services or connected objects. However, for non-programming users, the available possibilities for customizing their DA are limited and do not include the possibility of teaching the assistant new tasks. To make the most of the potential of DAs, users should be able to customize assistants by instructing them through Natural Language (NL). To provide such functionalities, NL interpretation in traditional assistants should be improved: (1) The intent identification system should be able to recognize new forms of known intents, and to acquire new intents as they are expressed by the user. (2) In order to be adaptive to novel intents, the Natural Language Understanding module should be sample efficient, and should not rely on a pretrained model. Rather, the system should continuously collect the training data as it learns new intents from the user. In this work, we propose AidMe (Adaptive Intent Detection in Multi-Domain Environments), a user-in-the-loop adaptive intent detection framework that allows the assistant to adapt to its user by learning his intents as their interaction progresses. AidMe builds its repertoire of intents and collects data to train a model of semantic similarity evaluation that can discriminate between the learned intents and autonomously discover new forms of known intents. AidMe addresses two major issues - intent learning and user adaptation - for instructable digital assistants. We demonstrate the capabilities of AidMe as a standalone system by comparing it with a one-shot learning system and a pretrained NLU module through simulations of interactions with a user. We also show how AidMe can smoothly integrate to an existing instructable digital assistant.

Phase diagram and magnetic properties of La$_{1-x}$Ca$_x$MnO$_3$ compound for $0\leq x \leq 0.23$

description: In this article a detailed study of La$_{1-x}$Ca$_x$MnO$_3$ ($0\leq x \leq 0.23$) phase diagram using powder x-ray diffraction and magnetization measurements is presented. Unfortunately, in the related literature no properly characterized samples have been used, with consequence the smearing of the real physics in this complicated system. As the present results reveal, there are two families of samples. The first family concerns samples prepared in atmosphere ($P({\rm O}_2)=0.2$ Atm) which are all ferromagnetic with Curie temperature rising with $x$. The second family concerns samples, where a post annealing in nearly zero oxygen partial pressure is applied. These samples show a canted antiferromagnetic structure for $0\leq x \leq 0.1$ below $T_N$, while for $0.125\leq x <0.23$ an unconventional ferromagnetic insulated phase is present below $T_c$. The most important difference between nonstoichiometric and stoichiometric samples concerning the magnetic behavior, is the anisotropy in the exchange interactions, in the stoichiometric samples putting forward the idea that a new orbital ordered phase is responsible for the ferromagnetic insulating regime in the La$_{1-x}$Ca$_x$MnO$_3$ compound.

description: The family of 2D materials grows day by day, drastically expanding the scope of possible phenomena to be explored in two dimensions, as well as the possible van der Waals heterostructures that one can create. Such 2D materials currently cover a vast range of properties. Until recently, this family has been missing one crucial member - 2D magnets. The situation has changed over the last two years with the introduction of a variety of atomically-thin magnetic crystals. Here we will discuss the difference between magnetic states in 2D materials and in bulk crystals and present an overview of the 2D magnets that have been explored recently. We will focus, in particular, on the case of the two most studied systems - semiconducting CrI$_3$ and metallic Fe$_3$GeTe$_2$ - and illustrate the physical phenomena that have been observed. Special attention will be given to the range of novel van der Waals heterostructures that became possible with the appearance of 2D magnets, offering new perspectives in this rapidly expanding field.

description: Nowadays, an important issue, taken up by both researchers and practitioners in the field of business management, is to find whether an applied method of value creation produces the anticipated effects (value added), not only from the perspective of the enterprise itself, but most of all, from the point of view of the ultimate customer. The aim of this article, on the basis of a profound analysis of literature on the subject being conducted, is to present an interpretation of the term of efficiency, which is explained differently and examined in relation to the given perspective (area of science). Moreover, in the article, there is an interpretation of the term of an efficient value chain of an enterprise given; in addition to that, various types of applicable approaches to the efficiency evaluation of a value chain of a business are presented, in a synthetic manner. Apart from showing several approaches, different criteria, which can be used while making an appraisal of efficiency of a value chain at different levels, were also depicted. This topic was taken up by the Author, taking into consideration the growing importance, which business managers attach to the implementation of measurement and assessment of efficiency of a value chain. It is an important problem from the perspective of selection or preparation of a successful model, allowing for a multidimensional evaluation of efficiency of management of the existing value chain of an enterprise, as well as the decision-making associated with the choice of a type of strategy, which would result in a company gaining or maintaining the competitive advantage in the market.

description: Undoped CoS$_2$ is an isotropic itinerant ferromagnet with a continuous or nearly continuous phase transition at $T_{\rm C} = 122$ K. In the doped CoS$_{1.9}$Se$_{0.1}$ system, the Curie temperature is lowered to $T_{\rm C} = 90$ K, and the transition becomes clearly first order in nature. In particular we find a discontinuous evolution of the spin dynamics as well as strong time relaxation in the ferromagnetic Bragg intensity and small angle neutron scattering in vicinity of the ferromagnetic transition. In the ordered state the long-wavelength spin excitations were found to be conventional ferromagnetic spin-waves with negligible spin-wave gap ($ < 0.04$ meV), indicating that this system is also an excellent isotropic (soft) ferromagnet. In a wide temperature range up to $0.9T_{\rm C}$, the spin-wave stiffness $D(T)$ follows the prediction of the two-magnon interaction theory, $D(T) = D(0)(1 - AT^{5/2})$, with $D(0) = 131.7 \pm 2.8$ meV-Å$^{2}$. The stiffness, however, does not collapse as $T \to T_{\rm C}$ from below. Instead a quasielastic central peak abruptly develops in the excitation spectrum, quite similar to results found in the colossal magnetoresistance oxides such as (La-Ca)MnO$_3$.

description: The CDF-S is the deepest X-ray image available and will remain so for the near future. We provide a spectroscopic (64.5%; 64% with spectral classifications) and photometric redshift catalog for the full 7 Ms sample, but much of our analysis focuses on the central (off-axis angles <5.7') region, which contains a large, faint ALMA sample of 75 >4.5-sigma 850 micron sources. We measure the 850 micron fluxes at the X-ray positions using the ALMA images, where available, or an ultradeep SCUBA-2 map. We find that the full X-ray sample produces ~10% of the 850 micron extragalactic background light. We separate the submillimeter detected X-ray sources into star-forming galaxies and AGNs using a star formation rate (SFR) versus X-ray luminosity calibration for high SFR galaxies. We confirm this separation using the X-ray photon indices. We measure the X-ray fluxes at the accurate positions of the 75 ALMA sources and detect 70% at >3-sigma in either the 0.5-2 or 2-7 keV bands. However, many of these may produce both their X-ray and submillimeter emission by star formation. Indeed, we find that only 20% of the ALMA sources have intermediate X-ray luminosities (rest-frame 8-28 keV luminosities of 10^42.5-10^44 erg/s), and none has a high X-ray luminosity (>10^44 erg/s). Conversely, after combining the CDF-S with the CDF-N, we find extreme star formation (SFR>300 solar masses per yr) in some intermediate X-ray luminosity sources but not in any high X-ray luminosity sources. We argue that the quenching of star formation in the most luminous AGNs may be a consequence of the clearing of gas in these sources.

description: Radical changes in the transition should enable the restructuring of the economy and financial markets, involvement in European and worldwide integration streams, influx of capital and creation of a favorable business environment. The creation of market infrastructure demands time and cannot, except in specific segments, be created by decrees. The implementation of changes in the economical and institutional environment has to be a sensibly channeled process. Apart from the reconstruction of the existing institutions, new institutions have to be created and substantial changes of their functioning have to be implemented. The underlying assumptions in the process of establishment of the goals and means of transforming the Serbian economy are the norms of a liberal market economy and the demands for an integral market and the universal action of market mechanisms. Thereby, a critical standpoint and selectiveness in the choice of methods for the creation of the transition, especially in the case of an installation of liberalism norms, must exist. The worldwide financial crisis points out the significant limitations of neoliberalism. The role of interventionism through state is more significant.

description: We experimentally investigate the atom-optical delta-kicked harmonic oscillator for the case of nonlinearity due to collisional interactions present in a Bose-Einstein condensate. A Bose condensate of rubidium atoms tightly confined in a static harmonic magnetic trap is exposed to a one-dimensional optical standing-wave potential that is pulsed on periodically. We focus on the quantum anti-resonance case for which the classical periodic behavior is simple and well understood. We show that after a small number of kicks the dynamics is dominated by dephasing of matter wave interference due to the finite width of the condensate's initial momentum distribution. In addition, we demonstrate that the nonlinear mean-field interaction in a typical harmonically confined Bose condensate is not sufficient to give rise to chaotic behavior.

description: At very high energies or small values of Bjorken x, the density of partons, per unit transverse area, in hadronic wavefunctions becomes very large leading to a saturation of partonic distributions. When the scale corresponding to the density per unit transverse area, the saturation scale Q_s, becomes large (Q_s\gg Λ_{QCD}), the coupling constant becomes weak (α_S(Q_s)\ll 1) which suggests that the high energy limit of QCD may be studied using weak coupling techniques. This simple idea can be formalized in an effective theory, the Color Glass Condensate (CGC), which describes the behavior of the small x components of the hadronic wavefunction in QCD. The Green functions of the theory satisfy Wilsonian renormalization group equations which reduce to the standard linear QCD evolution equations in the limit of low parton densities. The effective theory has a rich structure that has been explored using analytical and numerical techniques. The CGC can be applied to study a wide range of high energy scattering experiments from Deep Inelastic Scattering at HERA and the proposed Electron Ion Collider (EIC) to proton/deuterium-nucleus and nucleus-nucleus experiments at the RHIC and LHC colliders.

description: We paste together patches of $AdS_6$ to find solutions which describe two 4-branes intersecting on a 3-brane with non-zero tension. We construct explicitly brane arrays with Minkowski, de Sitter and Anti-de Sitter geometries intrinsic to the 3-brane, and describe how to generalize these solutions to the case of $AdS_{4+n}$, $n>2$, where $n$ $n+2$-branes intersect on a 3-brane. The Minkowski and de Sitter solutions localize gravity to the intersection, leading to 4D Newtonian gravity at large distances. We show this explicitly in the case of Minkowski origami by finding the zero-mode graviton, and computing the couplings of the bulk gravitons to the matter on the intersection. In de Sitter case, this follows from the finiteness of the bulk volume. The effective 4D Planck scale depends on the square of the fundamental 6D Planck scale, the $AdS_6$ radius and the angles between the 4-branes and the radial $AdS$ direction, and for the Minkowski origami it is $M_4{}^2 = {2/3} \Bigl(\tan α_1 + \tan α_2 \Bigr) M_*{}^4 L^2$. If $M_* \sim {\rm few} \times TeV$ this may account for the Planck-electroweak hierarchy even if $L \sim 10^{-4} {\rm m}$, with a possibility for sub-millimeter corrections to the Newton's law. We comment on the early universe cosmology of such models.

Positive feedback at the disc-halo interface

Subjects: subject: Astrophysics of Galaxies (astro-ph.GA)

description: The flat star formation (SF) history of the Milky Way (MW) requires gas in the Galactic disc to be replenished, most likely from a reservoir outside the Galaxy. Such a replenishment may be achieved by a form of `positive' feedback, whereby SF feedback creates a Galactic fountain cycle that collects and cools additional gas from the hot halo surrounding the Galaxy. In this paper we present a model of this process for the MW. A section of the Galactic disc is allowed to form stars which subsequently explode as supernovae (SNe) and send gas out into the hot halo. The gas that is sent out is colder than the hot halo gas and, as it mixes, the halo gas is cooled, providing fuel for further SF as the mixture falls back onto the Galactic disc. We find that this process can be sufficient to maintain a roughly-constant cold gas mass in the MW over at least 3 Gyr. Our results further suggest that there is a positive feedback trend whereby increasing SF leads to an increase in the cold gas budget at average SF rates below 0.5 solar masses per year but above which becomes negative, where further increasing the SFR causes the cold gas budget to decrease. We have constructed an analytical model for this that reproduces the data well and could have profound implications for galaxy evolution in feedback-dominated regimes.

The Good Place : An Investigation of Shopping Mall as Shared Public Space
Creators: name: Li, Weirong
Publisher: name: The University of British Columbia
Year: 2020

description: Shopping malls are one of the most important public spaces in contemporary public life. Since the 1950s, the privatization of malls and the replication of the shopping mall model all over the world have changed the way we experience them and our relationship with them. This project is an attempt to examine shopping mall as a type of public space to understand its unique spatial qualities that give rise to the series of complicated relationships formed within and with it over time. Ultimately, the project seeks to raise questions about what is valuable about a space and what constitutes a desirable public space through the lens of the shopping mall.

The sea and human culture and societies

description: No abstracts are to be cited without prior reference to the author.According to Article 8 of the Marine Strategy Framework Directive 2008/56/EC (MSFD) activities regarding the Initial Assessment (IA) of the Polish marine areas were carried out in Poland in 2010-2012. An important element of this assessment was the determination of the contaminants status and the evaluation of contaminant effects on biota in a quantitative way. Contamination of the marine environment by hazardous substances is regarded as an anthropogenic pressure factor significantly affecting the health of ecosystems. The assessment of hazardous substances status was carried out within descriptor 8: “Concentrations of contaminants are at levels not giving rise to pollution effects” and descriptor 9: “Contaminants in fish and other seafood for human consumption do not exceed levels established by Community legislation or other relevant standards”. Core indicators for the assessment were selected taking into account the recommendations of HELCOM CORESET Project, within which the indicators specific for the Baltic Sea area were designated. The applicability of the selected indicators was tested considering their representativeness in the assessed regions of the Polish sector of the Baltic Sea as well as taking into account data availability. Finally, 10 indicators for descriptor 8 and 9 indicators for descriptor 9 representing three groups of chemicals: persistent organic pollutants, heavy metals and radionuclides were selected for the Initial Assessment. Their concentrations determined in marine organisms (fish and mussels), marine sediments and water were compared with the reference values to calculate contamination ratios (CR). The contamination ratios were then translated into a 5- classification scheme following the FWD system of High, Good, Moderate, Poor and Bad status. The MSFD defined border between Good Environmental Status (GES) and sub-GES was assumed between the good and moderate status. The assessed sub-regions within the Polish sector of the Baltic Sea comprised transitional waters as well as the off-shore areas.
On the performance of HRPA(D) for NMR spin-spin coupling constants: Smaller molecules, aromatic and fluoroaromatic compounds

description: In this study, the performance of the doubles-corrected higher random-phase approximation (HRPA(D)) has been investigated in calculations of NMR spin-spin coupling constants (SSCCs) for 58 molecules with the experimental values used as the reference values. HRPA(D) is an approximation to the second-order polarization propagator approximation (SOPPA), and is therefore computationally less expensive than SOPPA. HRPA(D) performs comparable and sometimes even better than SOPPA, and therefore when calculating SSCCs it should be considered as an alternative to SOPPA. Furthermore, it was investigated whether a CCSD(T) or MP2 geometry optimization was optimal for a SOPPA and a HRPA(D) SSCCs calculation for 8 smaller molecules. CCSD(T) is the optimal geometry optimization for the SOPPA calculation, and MP2 was optimal for the HRPA(D) SSCC calculations.

Approximate Bayesian Updating: Sequential Inference for Streaming Data
Creators: name: Tomasetti, Nathaniel
Publisher: name: Monash University
Year: 2020
Subjects: Uncategorized

description: Bayesian models can be updated if additional data is observed, improving the quality of produced forecasts. However, the computational algorithms for Bayesian statistics are generally designed for only one update, and cannot be run again to add more data without discarding the previous result and starting again. This thesis proposes several approximate methods that allow models to be updated repeatedly, for use in applications when data is constantly being observed. These methods are shown to be faster than alternatives without significant loss of accuracy.
