description: Current quantum processors are noisy, have limited coherence and imperfect gate implementations. On such hardware, only algorithms that are shorter than the overall coherence time can be implemented and executed successfully. A good quantum compiler must translate an input program into the most efficient equivalent of itself, getting the most out of the available hardware. In this work, we present novel deterministic algorithms for compiling recurrent quantum circuit patterns in polynomial time. In particular, such patterns appear in quantum circuits that are used to compute the ground state properties of molecular systems using the variational quantum eigensolver (VQE) method together with the RyRz heuristic wavefunction Ansatz. We show that our pattern-oriented compiling algorithms, combined with an efficient swapping strategy, produces - in general - output programs that are comparable to those obtained with state-of-art compilers, in terms of CNOT count and CNOT depth. In particular, our solution produces unmatched results on RyRz circuits.

description: Magnetic tunnel junctions (MTJs) with partially oxidized 9 ÅAlO$_x$-barriers were recently shown to have the necessary characteristics to be used as magnetoresistive sensors in high-density storage devices. Here we study dielectric breakdown in such underoxidized magnetic tunnel junctions, focusing on its dependence on tunnel junction area and oxidation time. A clear relation between breakdown mechanism and junction area is observed for the MTJs with the highest studied oxidation time: samples with large areas fail usually due to extrinsic causes (characterized by a smooth resistance decrease at dielectric breakdown). Small area junctions fail mainly through an intrinsic mechanism (sharp resistance decrease at breakdown). However, this dependence changes for lower oxidation times, with extrinsic breakdown becoming dominant. In fact, in the extremely underoxidized magnetic tunnel junctions, failure is exclusively related with extrinsic causes, independently of MTJ-area. These results are related with the presence of defects in the barrier (weak spots that lead to intrinsic breakdown) and of metallic unoxidized Al nanoconstrictions (leading to extrinsic breakdown).

description: The safe zone concept combines knowledge about different aspects of mining and implements it into an IoT platform. This specific deliverable D4.4 discusses how to develop and integrate a sensoring concept, a data streaming concept and data analysis. The whole concept is divided into 4 safe zones: [Safe Zone 1] Intelligent rock bolts for geotechnical & atmospherical monitoring, [Safe Zone 2] Positioning/tracking of equipment & personnel, [Safe Zone 3] Environment monitoring (incl. acid mine drainage), [Safe Zone 4] Tailings dam stability. They are all different but going in the same direction – to make mining a safer space for both people and machines.

description: Results are presented of a comparison between solar wind speed estimates made using the time delays between 3 pairs of 327 MHz antennas at ISEE and estimates made by modeling the temporal power spectra observed with the 111 MHz BSA antenna at LPI. The observations were made for 6 years in the descending phase of solar cycle 24. More than 100 individual records were obtained for the compact source 3C48 and the extended and anisotropic source 3C298. The correlation between the daily speed estimates from 3C48 is 50%. Their annual averages agree within the error estimates and show the expected solar cycle variation. However the correlation between speeds from 3C298 is only 25% and their annual averages do not agree well. We investigate possible causes of this bias in the 3C298 estimated speeds.

description: Soft photons inside hadronic jets converted in front of the DELPHI main tracker (TPC) in events of qqbar disintegrations of the Z^0 were studied in the kinematic range 0.2 < E_gamma < 1 GeV and transverse momentum with respect to the closest jet direction p_T < 80 MeV/c. A clear excess of photons in the experimental data as compared to the Monte Carlo predictions is observed. This excess (uncorrected for the photon detection efficiency) is (1.17 +/- 0.06 +/- 0.27) x 10^{-3} gamma/jet in the specified kinematic region, while the expected level of the inner hadronic bremsstrahlung (which is not included in the Monte Carlo) is (0.340 +/- 0.001 +/- 0.038) x 10^{-3} gamma/jet. The ratio of the excess to the predicted bremsstrahlung rate is then (3.4 +/- 0.2 +/- 0.8), which is similar in strength to the anomalous soft photon signal observed in fixed target experiments with hadronic beams.

description: We report heating-compensated interlayer tunneling spectroscopy (ITS) performed on stacks of overdoped Bi$_2$Sr$_2$CaCu$_2$O$_{8+x}$ intrinsic junctions, where most of bias-induced heating in the ITS was eliminated. The onset temperature of the pseudogap (PG), revealed in the hump structure of the electronic excitation spectra, reached nearly room temperature for our overdoped intrinsic junctions, which represented the genuine PG onset. At a temperature below but close to $T_c$, both the superconducting coherence peak and the pseudogap hump coexisted, implying that the two gaps are of separate origins. The hump voltage increased below $T_c$, following the superconducting gap voltage, which led to a conclusion that the hump structure below $T_c$ in our ITS arose from the combined contribution of the quasiparticle spectral weights of two different characters; one of the superconducting state and another of the PG state near the antinodal region.

Rise of the ‘Machine Defendant’? A Cautionary Analysis and Conceptualisation of Civil and Criminal Liability Approaches to the Actions of Robots and Artificial Intelligence

description: Machines have been known to cause harm to humans, and liability for such harm has often been sheeted home to the natural or corporate persons behind the machines who have breached legal duties. With the rise of intelligent and autonomous machines which increasingly learn from external sources, the possibility of actions and ‘decision making’ by AIs that may not have been anticipated by those behind the machines increases. So too does the possibility that designers, manufacturers, owners, or users may argue that they could not reasonably foresee such actions or decisions by AI and so should not be held legally responsible for these actions when they cause harm. Solutions to the possibility that victims of harm may have no civil or criminal remedy range from laws analogising with liability for dangerous animals, to granting limited legal personality to AI. Yet strict or stricter liability on the manufacturers and promoters of AI appears to be the preferable policy option for remedying such harm for the foreseeable future.

description: Our goal in this work was to investigate the possible role and mechanism of regulated in development and DNA damage response 1 (REDD1) in mediating high glucose (HG)-induced podocyte injury in vitro. Mouse podocytes were stimulated with HG to establish HG injury model. Protein expression was examined by Western blotting. Cell viability was measured by cell counting kit-8 assay. Cell apoptosis was assessed by annexin V‐FITC/propidium iodide and TUNEL apoptotic assays. Levels of reactive oxygen species (ROS), malondialdehyde (MDA), superoxide dismutase (SOD), and glutathione peroxidase (GPx) were quantified by commercial kits. Concentrations of tumor necrosis factor (TNF)-α, interleukin (IL)-6, and IL-1β were measured by ELISA. A marked increase in REDD1 expression was observed in podocytes stimulated with HG. Reduced REDD1 expression strikingly restrained HG-induced increases in apoptosis, oxidative stress, and inflammation response in cultured podocytes. Decreasing REDD1 expression enhanced nuclear factor erythroid 2-related factor 2 (Nrf2) activation in HG-exposed podocytes via regulation of the AKT/glycogen synthase kinase-3 beta (GSK-3β) pathway. Inhibition of AKT or reactivation of GSK-3β prominently abolished Nrf2 activation induced by decreasing REDD1 expression. Pharmacological repression of Nrf2 markedly reversed the protective effects of decreasing REDD1 expression in HG-injured podocytes. Our data demonstrate that decreasing REDD1 expression protects cultured podocytes from HG-induced injuries by potentiating Nrf2 signaling through regulation of the AKT/GSK-3β pathway. Our work underscores the potential role of REDD1-mediated podocyte injury during the development of diabetic kidney disease.

description: The equilibrium states of one-dimensional proton conductors in the systems with hydrogen bonds are investigated. Our extended hard-core boson lattice model includes short-range interactions between hydrogen ions, their transfer along the hydrogen bonds with two-minima local anharmonic potential, as well as their inter-bond hopping, and the modulating field is taken into account. The exact diagonalization method for finite one-dimensional system with periodic boundary conditions is used. The existence of various phases of the system at $T = 0$, depending on the values of short-range interactions between particles and the modulating field strength, is established by analyzing the character of the obtained frequency dependence of one-particle spectral density; the phase diagrams are built.

Supermassive binary black holes among cosmic gamma-ray sources

description: Supermassive binary black holes (SBBHs) are a natural outcome of galaxy mergers. Here we show that low-frequency ($f \leq 10^{-6}$ Hz) quasi-periodic variability observed from cosmic blazar sources can provide substantial inductive support for the presence of close ($d \lppr 0.1$ pc) SBBHs at their centers. It is argued on physical grounds that such close binary systems are likely to give rise to different (although not independent) periodicities in the radio, optical and X-ray/TeV regime, and, hence that detection of appropriate period ratios significantly corroborates the SBBH interpretation. This is illustrated for a binary model where optical longterm periodicity is related to accretion disk interactions, radio periodicity to Newtonian jet precession, and periodicities in the high energy bands to the orbital motion of the jet. We use the observed periodicities to constrain the properties for a sample of SBBH candidates including OJ 287 and AO 0235+16, and discuss the results within the context of jet activity and binary evolution.

description: Motivation: In silico methods for the prediction of antigenic peptides binding to MHC class I molecules play an increasingly important role in the identification of T-cell epitopes. Statistical and machine learning methods, in particular, are widely used to score candidate epitopes based on their similarity with known epitopes and non epitopes. The genes coding for the MHC molecules, however, are highly polymorphic, and statistical methods have difficulties to build models for alleles with few known epitopes. In this case, recent works have demonstrated the utility of leveraging information across alleles to improve the performance of the prediction. Results: We design a support vector machine algorithm that is able to learn epitope models for all alleles simultaneously, by sharing information across similar alleles. The sharing of information across alleles is controlled by a user-defined measure of similarity between alleles. We show that this similarity can be defined in terms of supertypes, or more directly by comparing key residues known to play a role in the peptide-MHC binding. We illustrate the potential of this approach on various benchmark experiments where it outperforms other state-of-the-art methods.

description: The ability to accurately evaluate the performance of location determination systems is crucial for many applications. Typically, the performance of such systems is obtained by comparing ground truth locations with estimated locations. However, these ground truth locations are usually obtained by clicking on a map or using other worldwide available technologies like GPS. This introduces ground truth errors that are due to the marking process, map distortions, or inherent GPS inaccuracy. In this paper, we present a theoretical framework for analyzing the effect of ground truth errors on the evaluation of localization systems. Based on that, we design two algorithms for computing the real algorithmic error from the validation error and marking/map ground truth errors, respectively. We further establish bounds on different performance metrics. Validation of our theoretical assumptions and analysis using real data collected in a typical environment shows the ability of our theoretical framework to correct the estimated error of a localization algorithm in the presence of ground truth errors. Specifically, our marking error algorithm matches the real error CDF within 4%, and our map error algorithm provides a more accurate estimate of the median/tail error by 150%/72% when the map is shifted by 6m.

description: We develop a non-linear relativistic model of the Shapley Concentration (SC) and its environs, including the Great Attractor (GA) and the Local Group (LG). We take the Shapley concentration as a major attractive centre, and we use the Lemaitre-Tolman model. We constrain our model with present day observations, plus the requirement that it have a physically reasonable evolution from small perturbations at last scattering. We investigate possible mass and velocity distributions, and we find that the peculiar velocity maximum near the SC is \~800 km/s inwards, the density between GA and SC must be about ~0.9 times background, the mass of the GA is probably 4 - 6 x 10^15 M_sun, the SC's contribution to the LG motion is negligible, and the value of the cosmological constant is not significant on this scale.

Bulk-Brane Interaction and Holographic Dark Energy

description: In this paper we consider the bulk-brane interaction to obtain the equation of state for the holographic energy density in non-flat universe enclosed by the event horizon measured from the sphere of horizon named $L$. We assumes that the cold dark matter energy density on the brane is conserved, but the holographic dark energy density on the brane is not conserved due to brane-bulk energy exchange. Our calculation show, taking $Ω_Λ=0.73$ for the present time, the lower bound of $w_{\rm Λ}^{eff}$ is -0.9. This implies that one can not generate phantom-like equation of state from an interacting holographic dark energy model in non-flat universe.

Life and work: the health-related quality of life and employment outcomes of rental transplant recipients
Creators: name: Ferguson, Beryl M.
Publisher: name: University of British Columbia
Year: 2008

description: This study was designed to investigate patient outcomes following kidney transplantation in terms of health-related quality of life and employment status. In addition it was designed to identify, in terms of relative contribution, the main factors or characteristics that are associated with employment from the perspective of the renal transplant recipient. The study was conducted in two stages. In stage one, 216 adult renal transplant recipients from the lower mainland of British Columbia completed a mail questionnaire on their health-related quality of life and their employment circumstances. In stage two, using a maximum variation sampling strategy, seven adult transplant recipients participated in a personal interview. The results from this work indicate that a person's health-related quality of life following renal transplantation is less than optimal. Limitations persist particularly in the area of physical functioning and the ability to perform usual roles at home, school and work. The area least affected is the transplant recipients’ mental health. People with renal transplants generally adjust well to their condition and their mental health approaches the levels found in the general population. Employment prospects are diminished for people with kidney transplants. Employment rates lag behind the rates in the general population. The reasons for this finding are complex and reside in the individual as well as the socio-cultural, economic and political reality. When poor functional health is compounded by limited education, increased age, interruptions in work and the unavailability of suitable work, disadvantages in employment increase. The health and employment outcomes of renal transplant recipients provide estimates of the need for social work services and allow monitoring of progress toward meeting the goal of full rehabilitation in this population. Identifying and mapping the factors that contribute to employment using the PRECEDE-PROCEED model for health promotion planning and evalution is a useful guide to selecting and directing intervention where it is most needed. The findings of this study raise questions about quantifying a realistic employment goal for renal transplant recipients. It is recommended that further research be conducted to determine the barriers to employment found among other groups of chronically ill persons in order to develop a broad strategy for improving access and equal opportunity to jobs for all who desire them.

description: We attempt to quantify the widely-held belief that large hierarchies induced by strongly-warped geometries are common in the string theory landscape. To this end, we focus on the arguably best-understood subset of vacua -- type IIB Calabi-Yau orientifolds with non-perturbative Kaehler stabilization and a SUSY-breaking uplift (the KKLT setup). Within this framework, vacua with a realistically small cosmological constant are expected to come from Calabi-Yaus with a large number of 3-cycles. For appropriate choices of flux numbers, many of these 3-cycles can, in general, shrink to produce near-conifold geometries. Thus, a simple statistical analysis in the spirit of Denef and Douglas allows us to estimate the expected number and length of Klebanov-Strassler throats in the given set of vacua. We find that throats capable of explaining the electroweak hierarchy are expected to be present in a large fraction of the landscape vacua while shorter throats are essentially unavoidable in a statistical sense.

description: Spin tunneling in the particular case of the magnetic molecular cluster octanuclear iron(III), Fe8, is treated by an effective Hamiltonian that allows for an angle-based description of the process. The presence of an external magnetic field along the easy axis is also taken into account in this description. Analytic expressions for the energy levels and barriers are obtained from a harmonic approximation of the potential function which give results in good agreement with the experimental results. The energy splittings due to spin tunneling is treated in an adapted WKB approach and it is shown that the present description can give results to a reliable degree of accuracy.

description: Telerehabilitation systems for stroke survivors have been predominantly designed to measure and quantify movement in order to guide and encourage rehabilitation regular exercises at home. We set out to study what aspect of the movement data was essential, to better inform sensor design. We investigated face-to-face stroke rehabilitation sessions through a series of interviews and observations involving 16 stroke rehabilitation specialists including physiatrists, physical therapists, and occupational therapists. We found that specialists are not solely interested in movement data, and that experiential information about stroke survivors' lived experience plays an essential role in specialists interpreting movement data and creating a rehabilitation plan. We argue for a reconceptualization in stroke telerehabilitation that is more inclusive of non-movement data, and present design implications to better account for experiential information in telerehabilitation systems.

description: Mn ions' doping site and valence were studied in PbTiO$_{3}$ (PT) with the native vacancy defects by the first-principles calculations. Firstly, the native vacancy defects of Pb, O and Ti in PT were investigated and it was found that Pb vacancy is preferred to others. And then the growth of Mn doped PT should be preferred to Mn ion substituting for an A-site Pb ion with +3 valence when Pb is deficient under equilibrium conditions driven solely by minimization of the formation energy, and this could result in a larger lattice distortion of PT. In addition, when Mn enters the Pb site, the electronegativity of O becomes weaker which makes the domain movement easier in PT to improve the performance of PT, while Mn ion substitution for a B-site Ti ion is the opposite.

description: Objective: To analyze the clinical and biological significance of the acute promyelocytic leukemia (APL) whose PML-RARa transcripts increased after induction therapy. Methods: We analyzed 9 cases of APL whose PML-RARa transcripts increased after induction treatment and compare them with APL whose PML-RARa transcripts decreased. Results: The only factor affecting increased PML-RARa transcripts was the induction protocol. The cases of increased PML-RARa transcripts received induction treatment mainly based on ATRA and ATO. The evaluation of bone marrow aspirate cytology showed that the cell percentage from myelocyte to segmented neutrophil of the patients with increased PML-RARa transcripts was significantly higher than that of the patients with decreased PML-RARa transcripts. In the follow-up, MRD in 9 cases was consistently negative. Conclusions: Our studies showed the increased PML-RARa transcripts after induction treatment had different clinical significance from the decreased PML-RARa transcripts.

description: The GaAs/GaAsN interface band offset is calculated from first principles. The electrostatic potential at the core regions of the atoms is used to estimate the interface potential and align the band structures obtained from respective bulk calculations. First, it is shown that the present method performs well on the well-known conventional/conventional AlAs/GaAs (001) superlattice system. Then the method is applied to a more challenging nonconventional/conventional GaAsN/GaAs (001) system, and consequently type I band lineup and valence-band offset of about 35 meV is obtained for nitrogen concentration of about 3 %, in agreement with the recent experiments. We also investigate the effect of strain on the band lineup. For the GaAsN layer longitudinally strained to the GaAs lattice constant, the type II lineup with a nearly vanishing band offset is found, suggesting that the anisotropic strain along the interface is the principal cause for the often observed type I lineup.

description: Existing neural ranking models follow the text matching paradigm, where document-to-query relevance is estimated through predicting the matching score. Drawing from the rich literature of classical generative retrieval models, we introduce and formalize the paradigm of deep generative retrieval models defined via the cumulative probabilities of generating query terms. This paradigm offers a grounded probabilistic view on relevance estimation while still enabling the use of modern neural architectures. In contrast to the matching paradigm, the probabilistic nature of generative rankers readily offers a fine-grained measure of uncertainty. We adopt several current neural generative models in our framework and introduce a novel generative ranker (T-PGN), which combines the encoding capacity of Transformers with the Pointer Generator Network model. We conduct an extensive set of evaluation experiments on passage retrieval, leveraging the MS MARCO Passage Re-ranking and TREC Deep Learning 2019 Passage Re-ranking collections. Our results show the significantly higher performance of the T-PGN model when compared with other generative models. Lastly, we demonstrate that exploiting the uncertainty information of deep generative rankers opens new perspectives to query/collection understanding, and significantly improves the cut-off prediction task.

Έτσι, μορφολογικά, η εργασία αυτή αρθρώνεται μέσα από ένα συγκριτικό πλαίσιο των κανόνων που ισχύουν στο πεδίο των συνήθων πολιτικών δικών και αυτών που εφαρμόζονται στο πεδίο του κτηματολογικού δικονομικού δικαίου.
description: The procedural economy, the limitation of legal costs and the avoidance of contradictory judgments are ratios aimed at the single over-legislative objective of civil proceedings, namely the provision of effective judicial protection. The above objectives are achieved through legislative provisions of the current CCP, aimed at limiting trials either by subject or by object. This work is in order to examining the forms of subjectively complex proceedings of cadastral procedural law, i.e. all the rules governing proceedings relating to the application of land registry law in Greece, which could be described as almost procedural deviations from the usual forms of civil proceedings regulated in the CCP. Thus, morphologically, this thesis is articulated through a comparative framework of the rules applicable in the field of ordinary civil proceedings and those applicable in the field of cadastral procedural law.

description: Making an ansatz to the wave function, the exact solutions of the $D$% -dimensional radial Schrodinger equation with some molecular potentials like pseudoharmonic and modified Kratzer potentials are obtained. The restriction on the parameters of the given potential, $δ$ and $η$ are also given, where $η$ depends on a linear combination of the angular momentum quantum number $\ell $ and the spatial dimensions $D$ and $δ$ is a parameter in the ansatz to the wave function. On inserting D=3, we find that the bound state eigensolutions recover their standard analytical forms in literature.

description: We investigate the possibility of assigning consistent probabilities to sets of histories characterized by whether they enter a particular subspace of the Hilbert space of a closed system during a given time interval. In particular we investigate the case that this subspace is a region of the configuration space. This corresponds to a particular class of coarse grainings of spacetime regions. We consider the arrival time problem and the problem of time in reparametrization invariant theories as for example in canonical quantum gravity. Decoherence conditions and probabilities for those application are derived. The resulting decoherence condition does not depend on the explicit form of the restricted propagator that was problematic for generalizations such as application in quantum cosmology. Closely related is the problem of tunnelling time as well as the quantum Zeno effect. Some interpretational comments conclude, and we discuss the applicability of this formalism to deal with the arrival time problem.

description: Logistics management includes the most efficient and economical management of all activities in the supply chain, related to the storage, handling and transport of the products. Nowadays, logistics activities are outsourcing to 3PL providers in order for companies to reduce costs and focus on their main activities. 3PL are companies that undertake logistics activities on behalf of others. Since 3PL sector is an emerging industry, innovation management is deemed to be necessary for the development process in third party logistics companies. The aim of this thesis is to bring a holistic view of innovation management in 3PL companies. To achieve the objectives of this thesis, relevant literature was reviewed extensively in order for a better knowledge in this field to be formed. Specific databases were selected so as the different approaches that have been developed on this topic to be investigated and specific conclusions to be drawn. A second short research was also conducted aimed to confirm if the findings of the literature review are met in the Greek 3PL industry.
description: Η εφοδιαστική αλυσίδα περιλαμβάνει την αποτελεσματική και οικονομική διαχείριση όλων των δραστηριοτήτων στην αλυσίδα εφοδιασμού, που σχετίζονται με την αποθήκευση, την διαχείριση και την μεταφορά των προϊόντων. Στις μέρες μας, παρατηρείται πως οι δραστηριότητες της εφοδιαστικής ανατίθενται σε παρόχους υπηρεσιών Logistics (3PL) προκειμένου οι εταιρείες να πετύχουν μείωση του κόστους και να επικεντρωθούν στις βασικές τους λειτουργίες. Οι πάροχοι υπηρεσιών Logistics, είναι ουσιαστικά εταιρείες που αναλαμβάνουν να διεκπεραιώσουν για λογαριασμό άλλων τη διαχείριση της εφοδιαστικής αλυσίδας. Δεδομένου ότι ο τομέας 3PL είναι μια αναδυόμενη βιομηχανία, απαραίτητο στοιχείο για την εξέλιξη του θεωρείται η καινοτομία. Στόχος αυτής της διατριβής είναι να προσφέρει μια σφαιρική άποψη για τηn ύπαρξη καινοτομίας στις υπηρεσίες των παρόχων υπηρεσιών Logistics προς τρίτους (3PL). Για να επιτευχθούν οι στόχοι της διπλωματικής εργασίας, μελετήθηκε εκτενώς η σχετική βιβλιογραφία προκειμένου να συγκεντρωθεί η ήδη υπάρχουσα γνώση σε αυτό το αντικείμενο. Επιλέχθηκαν συγκεκριμένες βάσεις δεδομένων ούτως ώστε να εξεταστούν οι διάφορες προσεγγίσεις που έχουν αναπτυχθεί για αυτό το θέμα και να αντληθούν συγκεκριμένα συμπεράσματα. Μια δεύτερη σύντομη έρευνα διεξήχθη επίσης με σκοπό να διασταυρώσει αν τα ευρήματα της βιβλιογραφικής ανασκόπησης συναντώνται στην ελληνική βιομηχανία 3PL.

description: RESUMO

Nos últimos anos, registou-se o aumento significativo do número de IES e de cursos, e, por conta disso, a garantia da qualidade é possível utilizando as boas práticas de avaliação e acreditação, através da implementação de instrumentos universalmente consagrados. Em Angola, a cultura de avaliação é ainda esparsa com iniciativas isoladas e sobretudo incipientes. Assim, o presente artigo visa analisar o Sistema Nacional de Garantia da Qualidade do Ensino Superior (SNGQES) em Angola como instrumento para o alcance dos ODS 4 sobre a Qualidade da Educação. Neste sentido, o artigo busca responder a seguinte questão: de que forma o SNGQES pode garantir o alcance da qualidade prevista no ODS 4? Quanto à metodologia aplicada, este artigo é de abordagem qualitativa-descritiva com recurso à análise bibliográfica exploratória. Os resultados mostram que estão criadas as condições para a implementação dos diferentes instrumentos legais existentes, que se constituem nos pressupostos do Sistema Nacional de Garantia da Qualidade do Ensino Superior, nomeadamente, a Legislação, tal como o Regime Jurídico da Avaliação e Acreditação da Qualidade das Instituições de Ensino Superior, e os instrumentos técnico-operacionais, nomeadamente, o Guião de Auto-avaliação de Instituições de Ensino Superior e os Manuais de Avaliação Externa de Instituições e cursos e ou programas do Ensino Superior. O estudo conclui que, por meio da avaliação dos cursos e/ou programas das IES e do ensino superior como um todo, levados a cabo pelo INAAREES, como pressuposto para a concretização do SNGQES, é possível enraizar a cultura da qualidade e alcançar o ODS 4, na medida em que a avaliação da qualidade no Ensino Superior consubstancia-se num processo contínuo e não pontual em que o objectivo último não é a avaliação e a acreditação em si, mas os recursos a estes dois mecanismos para garantir e elevar, permanentemente, a qualidade nas IES.

Charge distribution and screening in layered graphene systems
Creators: name: Guinea, F.
Publisher: name: arXiv
Year: 2006
Subjects: subject: Mesoscale and Nanoscale Physics (cond-mat.mes-hall)

description: The charge distribution induced by external fields in finite stacks of graphene planes, or in semiinfinite graphite is considered. The interlayer electronic hybridization is described by a nearest neighbor hopping term, and the charge induced by the self consistent electrostatic potential is calculated within linear response (RPA). The screening properties are determined by contributions from inter- and intraband electronic transitions. In neutral systems, only interband transitions contribute to the charge polarizability, leading to insulating-like screening properties, and to oscillations in the induced charge, with a period equal to the interlayer spacing. In doped systems, we find a screening length equivalent to 2-3 graphene layers, superimposed to significant charge oscillations.

description: We analytically study quantum dissipative dynamics described by the Caldirola-Kanai model with inter-particle interactions. We have found that the dissipative quantum dynamics of the Caldirola-Kanai model can be exactly mapped to a dissipationless quantum dynamics under a negative external harmonic potential, even when the particles are strongly interacting. In particular, we show that the mapping is valid for the unitary Fermi gas, which is relevant for cold atoms and nuclear matters.

Publisher: name: University of British Columbia
Year: 2008

description: The acquisition of records from environmental non-governmental organizations will be of increasing interest to archivists over the next few years. The impact of these organizations on our society is only beginning to be felt. Their records will form an important facet of our documentary heritage. This thesis studies the approaches which might be taken for the strategic acquisition of these records by archival repositories and programs. Environmental non-government organizations are examined in light of the development of the movement, the general structure of the organizations, and in greater detail through a survey of organizations in British Columbia. The results of this survey indicate the possibilities for successful acquisition of these records through cooperative interinstitutional strategies, acquisition strategies, and documentation strategies.
