Compliance re-examined : a study of nurses’ perceptions of and responses to in-hospital maintenance hemodialysis patients whom nurses perceived to be noncompliant
Creators: name: Gaudet, Denise Marie
Publisher: name: University of British Columbia
Year: 2008

description: The respective rights and responsibilities of the nurse and the patient may be a source of conflict as nurses and patients do not always agree on behaviors and attitudes necessary for adjustment to life on hemodialysis. The investigator had observed that hemodialysis nurses’ responses to patients who deviate from the recommended medical regime varied significantly. The question arose as to why there are differences in nurses' responses to perceived noncompliant patient behaviors. Only one study was found which examined emotional reactions and behaviors of nurses as part of a multidisciplinary hemodialysis team, toward their patients (Kaplan De-Nour & Czackes, 1968). The purpose of this study was to investigate specifically hemodialysis nurses’ perceptions of noncompliant in-hospital maintenance hemodialysis patient behaviors and their responses to such patient behaviors. A phenomenological research method was used to explore nurses' lived experience of caring for hemodialysis patients. Eight nurses were selected as participants for the study from hemodialysis units in two hospitals from the Lower Vancouver Mainland area. These nurses participated in one to three audiotaped interviews using open-ended questions. Data collection and analysis occurred concurrently following Colaizzi's (1978) method of analysis. Field notes and verbatim transcriptions of the audiotapes interviews were used as data for analysis. The process of labelling and judging compliant or noncompliant patients was unique to each nurse and was linked with the degree of congruence between nurses' and patients' expectations and the nurses' sense of empowerment or powerlessness. There were two sources of empowerment or powerlessness: nurse-patient relationships and the workplace. The key factor which seemed to determine the nature of nurse-patient relationships the notion of reciprocity was based on shared responsibility with patients and mutual respect. In terms of the work environment, mutual concern and support from peers and colleagues contributed to nurses’ sense of empowerment. Nurses' perceived lack of control over work place conditions caused them to feel powerless. Nurses used several coping strategies to deal with their feelings of powerlessness. Discussion of the findings occurs in conjunction with relevant literature. Implications for nursing practice, nursing administration, and nursing education are identified. Finally, further research suggestions are made.

description: Bibliothekare in Öffentlichen Bibliotheken müssen schon lange mehr sein als gute Fachkräfte. Tiefgreifende Veränderungen haben sich in organisatorischer, finanzieller und personeller Hinsicht durch die Einführung des neuen Steuerungsmodells in den deutschen Kommunen ergeben, das die Grundlagen und Gestaltungsmöglichkeiten des Verwaltungshandelns stark ausgebaut hat. Gleichzeitig hat sich das Mediennutzungsverhalten der Nutzer grundlegend geändert und aufgrund der zunehmenden Digitalisierung erfolgt erheblicher Wandel in Bereichen wie Bestandsentwicklung und -präsentation sowie Erschließung. Die Gesamtheit der Entwicklungen erfordert neue Fortbildungskonzepte. Für Bibliothekare ist ein Höchstmaß an inhaltlicher Flexibilität sowie Lern- und Veränderungsbereitschaft gefragt, um die eigene Einrichtung zukunftsfähig gestalten zu können. Fortbildungen der Zukunft sollten daher sowohl die fachlichen Kompetenzen als auch die Entwicklung der Persönlichkeit im Fokus haben und diese im Idealfall als ganzheitliche Fortbildungseinheiten integrativ vermitteln. Facetten wie Teamteaching und Transferaufgaben tragen darüber hinaus zur Abrundung und Optimierung der Konzepte bei.

description: The main objective of this thesis is to introduce, prove and evaluate novel efficient methods for the effective search and retrieval of 3d objects based on their geometrical characteristics. Since there is not an universal accepted theory concerning the way that the 3d objects are analyzed, many algorithms were introduced by us so as to find the most suitable descriptions, which come in compressed, the information of the 3D objects. Additionally, the creative of new effective matching methods war of great importance. The proposed algorithms have been is serted into a web-based tool as a proof of concept, which is available at "http://www.iti.gr". Finally, some of the methods were used for copyright protection and classification of 3D macromolecules. A 3D authoring tool capable of creating MPEG-4 audiovisual scenes was also introduced
The Long Way to Deforestation (Technical Report): A Type Inference and Elaboration Technique for Removing Intermediate Data Structures
Creators: name: Chen, Yijia

subject: FOS: Computer and information sciences

description: Deforestation is a compiler optimization that removes intermediate data structure allocations from functional programs to improve their efficiency. This is an old idea, but previous approaches have proved limited or impractical: they either only worked on compositions of predefined combinators (shortcut fusion), or involved the aggressive unfolding of recursive definitions until a depth limit was reached or a reoccurring pattern was found to tie the recursive knot, resulting in impractical algorithmic complexity and large amounts of code duplication. We present Lumberhack, a general-purpose deforestation approach for purely functional call-by-value programs. Lumberhack uses subtype inference to reason about data structure production and consumption and uses an elaboration pass to fuse the corresponding recursive definitions. It fuses large classes of mutually recursive definitions while avoiding much of the unproductive (and sometimes counter-productive) code duplication inherent in previous approaches. We prove the soundness of Lumberhack using logical relations and experimentally demonstrate significant speedups in the standard nofib benchmark suite.

description: The high cost of density functional theory has hitherto limited the ab initio prediction of equation of state (EOS). In this article, we employ a combination of large scale computing, advanced simulation techniques, and smart data science strategies to provide an unprecedented, ab initio performance analysis of the high explosive pentaerythritol tetranitrate (PETN). Comparison to both experiment and thermochemical predictions reveals important quantitative limitations of DFT for EOS prediction, and thus the assessment of high explosives. In particular, we find DFT predicts the energy of PETN detonation products to be systematically too high relative to the unreacted neat crystalline material, resulting in an underprediction of the detonation velocity, pressure, and temperature at the Chapman-Jouguet (CJ) state. The energetic bias can be partially accounted for by high-level electronic structure calculations of the product molecules. We also demonstrate a modeling strategy for mapping chemical composition across a wide parameter space with limited numerical data, the results of which suggest additional molecular species to consider in thermochemical modeling.

description: Velocity-space anisotropy can significantly modify fusion reactivity. The nature and magnitude of this modification depends on the plasma temperature, as well as the details of how the anisotropy is introduced. For plasmas that are sufficiently cold compared to the peak of the fusion cross-section, anisotropic distributions tend to have higher yields than isotropic distributions with the same thermal energy. At higher temperatures, it is instead isotropic distributions that have the highest yields. However, the details of this behavior depend on exactly how the distribution differs from an isotropic Maxwellian. This paper describes the effects of anisotropy on fusion yield for the class of anisotropic distribution functions with the same energy distribution as a 3D isotropic Maxwellian, and compares those results with the yields from bi-Maxwellian distributions. In many cases, especially for plasmas somewhat below reactor-regime temperatures, the effects of anisotropy can be substantial.

PHRASEOLOGISMS DENOTING POSITIVE MORAL QUALITIES
Creators: name: Babaqulova, Oydin
Publisher: name: Zenodo
Year: 2023

description: This scientific article explores the diverse landscape of phraseologisms that encapsulate positive moral qualities within the English language. From expressions reflecting virtues like kindness and integrity to idioms embodying ethical principles, the study aims to provide a comprehensive analysis of how language encapsulates and conveys positive moral values. The examination extends beyond linguistic structures to encompass cultural, cognitive, and communicative dimensions, offering a holistic understanding of phraseologisms as linguistic vehicles for the expression of virtuous qualities. This scientific article endeavors to shed light on phraseologisms that encapsulate positive moral qualities across diverse linguistic traditions. Drawing from idiomatic expressions, proverbs, and fixed phrases, we delve into the linguistic manifestations of virtues such as integrity, compassion, resilience, and altruism. Through a multifaceted analysis, this study aims to unravel the cultural, cognitive, and linguistic dimensions of phraseologisms denoting positive moral qualities, contributing to a deeper understanding of the universal and culture-specific aspects of ethical discourse.

Moreover the chameleon field model is compatible with the CAST results, fifth force experiments and cosmology.

We discuss the role of the finite spatial extension of composite baryons on dynamical and statistical properties such as the Landau parameters, the compressibility, and the symmetry energy. We have also calculated the low lying collective eigenfrequencies arising from the collisionless quasiparticle transport equation, considering both unstable and stable modes. An overall analysis of the excluded volume correlations on the collective properties is performed.

description: A muonium hydride molecule is a bound state of muonium and hydrogen atoms. It has half the mass of a parahydrogen molecule and very similar electronic properties in its ground state. The phase diagram of an assembly of such particles is investigated by first principle quantum simulations. In the bulk limit, the low-temperature equilibrium phase is a crystal of extraordinarily low density, lower than that of any other known atomic or molecular crystal. Despite the low density and particle mass, the melting temperature is surprisingly high (close to 9 K). No (metastable) supersolid phase is observed. We investigated the physical properties of nanoscale clusters (up to 200 particles) of muonium hydride and found the superfluid response to be greatly enhanced compared to that of parahydrogen clusters. The possible experimental realization of these systems is discussed.

description: The effect of nuclear deformation on the energy distributions of the Gamow-Teller strength is studied in neutron-deficient Hg, Pb, and Po even isotopes. The theoretical framework is based on a self-consistent deformed Skyrme Hartree-Fock mean field with pairing correlations between like nucleons in BCS approximation and residual spin-isospin interactions treated in the proton-neutron quasiparticle random phase approximation. After a systematic study of the Gamow-Teller strength distributions in the low excitation energy region, relevant for beta-decay, we have identified the best candidates to look for deformation signatures in their beta-decay patterns. beta+ half-lives and total Gamow-Teller strengths B(GT+) and B(GT-) are analyzed as well.

description: Since the late 1920s, a portion of the research into Indian education in Canada has included measuring the intelligence of students using standardized tests. Consistent results and explanations of these results have evolved into a debate on the legitimacy surrounding the use of these tests among cultural groups for which they have not been normed. This review focuses on (a) the current debate on the nature of intelligence, (b) the present controversy on the use of standardized intelligence tests, (c) the arguments surrounding the intelligence testing of Canadian Native students, (d) the language barrier in standardized intel­ligence testing, (e) the role of academic self-concept in Native education, and (f) the role of parental attitudes toward education. The article concludes with sugges­tions for the future of Native education.

description: We investigate a set of topological arrangements of individual ferromagnetic islands in ideal and disordered artificial spin ice (ASI) arrays in order to evaluate how aspects of their field-driven reversal are affected by the model used. The set contains the pinwheel and square ice tilings, and thus a range of magnetic ordering and reversal properties are tested. We find that a simple point dipole model performs relatively well for square ice, but it does not replicate the properties observed in recent experiments with pinwheel ice. Parameterization of the reversal barrier in a Stoner-Wohlfarth model improves upon this, but fails to capture aspects of the physics of ferromagnetic coupling observed in pinwheel structures which have been attributed to the non-Ising nature of the islands. In particular, spin canting is found to be important in pinwheel arrays, but not in square ones, due to their different symmetries. Our findings will improve the modelling of ASI structures for fundamental research and in applications which are reliant upon the ability to obtain and switch through known states using an externally applied field.

description: We report on a uniform comparative analysis of the fundamental parameters of early-type galaxies at z~1 down to a well defined magnitude limit (M_B\leq -20.0 in the field and M_B\leq -20.5 in the clusters). The changes in the M/L_B ratio from z~1 to today are larger for lower mass galaxies in all environments, and are similar in the field and in the clusters for galaxies with the same mass. By deriving ages from the M}/L_B ratio, we estimate the formation redshift for early-type galaxies as a function of galaxy mass and environment. We find that the age of early-type galaxies increases with galaxy mass (downsizing) in all environments, and that cluster galaxies appear to have the same age within 5% as field galaxies at any given galaxy mass. The first result confirms similar ones obtained by other means, while the second one is controversial. The most recent incarnation of the hierarchical models of galaxy formation and evolution is capable of explaining the first result, but predicts that cluster galaxies should be older than field galaxies. We also find a total lack of massive early--type galaxies M>3 10^{11} M_{\sun}) with a formation redshift smaller than 2, which cannot be due to selection effects.

description: Graphene oxide (GO)-based humidity sensors are attracting widespread attention due to their high responsivity and low cost. However, GO-based humidity sensors generally suffer from slow response and recovery as well as poor stability,etc. Here, we reported a flexible resistive humidity sensor based on a MoS2/GO composite film that was fabricated by mixing different volumes of MoS2 and GO dispersions with adjustable volume ratios. The MoS2/GO composite film has been used as a sensing layer on screen-printed interdigital electrodes. The results show that the best device performance was achieved at a dispersion volume of 0.05 mL with the MoS2/GO volume ratio of 5:1, featuring high responsivity (~98%), fast response/recovery time (1.3/12.1 s), excellent stability and low cost. Further, the humidity sensor exhibits good linearity over a wide humidity range (33% RH-98% RH) at room temperature and can be fabricated easily and feasibly. The application of the humidity sensors we prepared in human respiration detection and human fingertip proximity detection has been demonstrated. These findings indicate the great potential of the composite of MoS2/GO in developing the next generation of high-performance humidity sensors.

description: Purpose: This longitudinal study examined the development of prelinguistic skills and the continuity of communication and language from the prelinguistic stage to school age. Method: Prelinguistic communication of 427 Finnish children was followed repeatedly from 6 to 18 months of age (n = 203–322 at ages 6, 9, 12, 15, and 18 months), and its associations with language ability at ages 2;0 (n = 104), 3;0 (n = 112), 4;7 (n = 253), 5;3 (n = 102), and 7;9 (n = 236) were examined using latent growth curve modeling. Results: Prelinguistic development across several skills emerged as a rather stable intraindividual characteristic during the first 2 years of life. Continuity from prelinguistic development to later language ability was indicated. The common level and growth of prelinguistic skills were significant predictors of language ability between ages 2;0 (years;months) and 7;9; the percentage explained varied between 10.5% and 53.3%. A slow pace of development across multiple skills, in particular, led to weaker language skills. Conclusions: The results support (a) the idea of a developmental continuum from prelinguistic to linguistic ability and (b) the dimensional view of language ability by indicating that individual variations in early communication skills show consistency that extends beyond the toddler years. Our results also advocate developmental surveillance of early communication by emphasizing the significance of growth in predicting language development.
Fuite hors de l’objet Joseph Kosuth et Robert Smithson ̀la fin des années soixante
Creators: name: Bérard, Serge
Publisher: name: University of British Columbia
Year: 2008

description: The conceptual art of Joseph Kosuth and the earthworks of Robert Smithson mark, at the end of the sixties, a radical break from the modernist and formalist tradition in that they reject the art object. While minimalism signals the end point of a strategy of negation (Adorno) at it has been carried inside the "system of the object", Kosuth and Smithson will try to escape this system in two opposite directions. The inverse symmetry of their reactions will be emphasize as it reflects two major changes that affect American society at that time: a structural change in the modes of production defined by the decline of the manufacturing sector and the emergence of the technologies of information; an ideological change defined by the replacement of the emphasis on consumerism and the faith in scientific and technological progress by the doomsday scenario of the ecologists with their attack on the dogma of unlimited growth. It will be shown that, while they both reject the manufactured object, Kosuth continues the negation of the minimalists onto the tertiary sector of linguistic technologies while, inversely, Smithson goes back to the primary sector of the extraction of matter and its infrastructure. Kosuth's use of Wittgenstein's philosophy makes explicit his capitulation in front of the latest, linguistic, move of instrumental reason, and to capitulate is still an hostile gesture. Smithson's use of the scenario of the ecologists, and his rejection of the accelerated time of technology and its environmental legacy, will end in entropic, morbid despair.

description: We present an estimate for the non-linear parameter τ_NL, which measures the non-gaussianity imprinted in the trispectrum of the comoving curvature perturbation, ζ. Our estimate is valid throughout the inflationary era, until the slow-roll approximation breaks down, and takes into account the evolution of perturbations on superhorizon scales. We find that the non-gaussianity is always small if the field values at the end of inflation are negligible when compared to their values at horizon crossing. Under the same assumption, we show that in Nflation-type scenarios, where the potential is a sum of monomials, the non-gaussianity measured by τ_NL is independent of the couplings and initial conditions.

description: The concentration of various physicochemical parameters, nutrients, heavy metals and radiocesium in water, sediments and water plants of river Pinios was studied. Samples were monthly collected and analyzed during the period 1996-1998. nine sampling sites along the river Pinios and its tributes were selected for the analysis of nutrients in water samples and radiocesium(Cs-137) in sediment and water plants samples. Also three sampling sites of the above nine were selected for the paramenters(physical or chemical) measured in this survey exhibited high spatial and temporal variability. Among the studied areas along the river Pinios the most heavily polluted were near the Larisa city where sewage and industrial discharges occur. For the evaluation of heavy metals pollution in river Pinios a comparison study was carried out in three sampling sites by selecting the same species of water plants in all stations. Among the three sites, the most polluted in all heavy metals for both sentiment and plants appeared to be the second site. Also the heavy metals concentration was variable amongst the plants in the same site. It is clear that some water plants species possess higher ability of heavy metals biocummulation. Cs-137 concentration activities are higher in sediment than in plant material. In general,roots showed greater Cs-137 concentration than leaves, while stems showed the lowest concentration

sub-Saharan Africa

description: African education research is often ‘overlooked and undervalued’ in global policy debates (Maclure 2006). This paper reports on a project to catalogue education research from sub-Saharan Africa (SSA) for the purpose of raising its visibility and strengthening the evidence base for national, regional and global policy and practice. The paper combines large-scale bibliometric analysis of education research outputs from 48 countries in SSA with a qualitative study of the priorities of African researchers. The study highlights the perspectives of African research and researchers with respect to informing the Education Sustainable Development Goal. Attention is given to areas of convergence and tension between global policy agendas and African researchers’ priorities for knowledge production. The quantitative analysis draws from structured searches of academic and grey literature databases, together with a process of expert consultation. The search sought to identify social science research outputs with implications for education policy and practice conducted by researchers in SSA over the period 2007-2017. Patterns and trends are identified regarding publication type, thematic foci, research methods, funding, and citations. The qualitative component derives from semi-structured interviews with African researchers and a range of non-academic stakeholders, including representatives of government agencies and NGOs. Thematic analysis was informed by previous studies of evidence use in education policy-making (Brown 2014). The paper considers lessons for the identification of research topics, research design and dissemination to enhance the visibility of African research in national and global policy debates. It further aims to support future research partnerships to inform the SDGs which are grounded in African knowledge and expertise.

description: Σκοπός της διατριβής είναι η εδραίωση του φιλοσοφικού προβλήματος της πραγματικότητας στη βάση μιας εμπειρικής έρευνας σχετικά με τη δημοσιογραφική κάλυψη του πολέμου στο Ιράκ το έτος 2003 από τα ΜΜΕ. Προκειμένου να ορίσουμε την εννοια του πραγματικού οδηγούμαστε στις απαρχές της φιλοσοφίας : τον Παρμενίδη, τον Πλάτωνα, τον Πλωτίνο. Στη συνέχεια μελετούμε τη διαμόρφωση της έννοιας της πραγματικότητας σύμφωνα με σύγχρονες θεωρίες τηα μαζικής επικοινωνίας : φιλελευθερισμός, μαρξισμός, τεχνολογικός ντετερμινισμός, δομισμός, μεταμοντερνισμός, πολιτιστική, ψυχολογική προσέγγιση. Σύμφωνα με τα στοιχεία της εμπειρικής έρευνας, τα ΜΜΕ δεν παρουσίασαν μια, αλλά πολλές παράλληλες ή αντικρουόμενες πραγματικότητες του πολέμου στο Ιράκ. Επομένως αντιλαμβανόμαστε μια κοινή πραγματικότητα με πολλούς διαφορετικούς τρόπους
description: The aim of the thesis consists in foundation of the philosophical problem of reality on the basis of an empirical study regarding the media coverage of the war in Iraq in 2003. In order to define the notion of reality we are led to the beginnings of philosophy : Parmenides, Plato, Plotinus. We then examine the notion of reality according to modern theories of mass communication : liberalism, marxism, technological determinism, constructivism, postmodernism and cultural psychological approaches. According to the data of our empirical research, the mass media did not present one but many different notions of the reality of the war in Iraq. Therefore it is possible to perceive the same reality in many different forms
The Search in Australian Aboriginal Education: Recent Developments and Bilingual Education

description: An exploration of developments in Australian Aboriginal education over the past few decades demonstrates the value of a historical perspective. Despite the important legal changes of 1967, the 1970s appeared to be a decade of inactivity insofar as the improvement of Aboriginal education was concerned. However, this did not necessarily indicate continued neglect of Aboriginals. Rather, time was required to meaningfully address the deep-rooted problems and issues of Aboriginal education. Ultimately, the educational programs of the 1980s, such as bilingual education, benefited from these years of reflection. The foundation of these programs is Aboriginal self-determination, and a fundamental objective is enhanced Aboriginal self-awareness.

description: We investigate how insights from statistical physics, namely survey propagation, can improve decoding of a particular class of sparse error correcting codes. We show that a recently proposed algorithm, time averaged belief propagation, is in fact intimately linked to a specific survey propagation for which Parisi's replica symmetry breaking parameter is set to zero, and that the latter is always superior to belief propagation in the high connectivity limit. We briefly look at further improvements available by going to the second level of replica symmetry breaking.

description: Σκοπός της διατριβής είναι ο καθορισμός της φάσης εξέλιξης του αναγλύφου της τ/φ Σερρών και του δικτύου του ποταμού Στρυμόνα πριν και μετά τις ανθρωπογενείς επεμβάσεις στην πεδινή ζώνη της. Η εξέταση των γεολογικών-κλιματικών δεδομένων, η χαρτογράφηση-μελέτη του αναγλύφου και των γεωμορφών του, η ανάλυση των παραμέτρων του δικτύου και η διερεύνηση των επιπτώσεων στο φυσικό περιβάλλον, κατέληξε ότι : 1) διακρίνονται γεωμορφές : α)διάβρωσης(π.χ. επιφένειες επιπέδωσης, glacis, gallies κλπ.) β)απόθεσης(π.χ. αλλουβιακά ριπίδια και προσχωσιγενείς σχηματισμοί) που ανήκουν σε 3-4 γενιές 2)το υδρογραφικό δίκτυο αναπτύσσεται ομαλά και συμμετρικά με άξονα του Στρυμόνα. Ανήκει δε σε τέσσερεις(4) γενιές. Οι γενιές αυτές, συνδέουν με διαδοχικές αλλαγές των ενδογενών(τεκτονική) και εξωγενών(κλίμα) διεργασιών από το Νεογενές έως σήμερα 3)Οι μεγάλης κλίμακας ανθρωπογενείς επεμβάσεις, στην χαμηλή ζώνη της τ/φ κυριαρχούν στις σύγχρονες εξωγενείς διεργασίες, προκαλούνται σοβαρές αλλαγές και επιβαρύνσεις στους υδατικούς πόρους στο έδαφος, στο περιβάλλον και στις ανθρώπινες δραστηριότητες. Συμπερασματικά προκύπτει ότι στις ημιορεινές και ορεινές περιοχές της τ/φ Σερρών συνεχίζουν οι φυσικές διεργασίες και ότι το υδρογραφικό δίκτυο του Στρυμόνα, στην τ/φ Σερρών είναι ένα μεικτό φυσικό-ανθρωπογενές δίκτυο
description: Detailed geomorphological analysis of the river Strymon network in Serres graben carried out in this thesis. The collected data yield evidence of the influence of the endogenic(tectonic) and exogenic(climatic) process upon the dynamic evolution of this network. The human impact have also considerable effect upon the recent development of the network. Geomorphological mapping carried out in Serres graben, revealed a great variety of land forms, given in the geomorphological map of this thesis. They can be distinguised mainly into erosional and depositional landforms. Four(4) generations of rivers networks and basins were recognized within the Serres graben as a result of four(4) stages, development(neotectonic movements). Through a series of human works during the 20th century, the entire low area of Serres plain and low hills were modified. The collected data from both natural and human changes in Serres graben indicated that the river network and basin network are now under natural and human control

description: Spectral distribution theory, which can be used to compare microscopic interactions over a broad range of nuclei, is applied in an analysis of two modern effective interactions based on the realistic CD-Bonn potential for $0\hbarΩ$ no-core shell model calculations in the fp shell, as well as in a comparison of these with the realistic shell-model GXPF1 interaction. In particular, we explore the ability of these interaction to account for the development of isovector pairing correlations and collective rotational motion in the fp shell. Our findings expose the similarities of these two-body interactions, especially as this relates to their pairing and rotational characteristics. Further, the GXPF1 interaction is used to determine the strength parameter of a quadrupole term that can be used to augment an isovector-pairing model interaction with Sp(4) dynamical symmetry, which in turn is shown to yield reasonable agreement with the low-lying energy spectra of $^{58}$Ni and $^{58}$Cu.

description: We previously introduced [T. Cren et al., Europhys. Lett. 52, 203 (2000)] an energy-dependant gap function, $Δ(E)$, that fits the unusual shape of the quasiparticle (QP) spectrum for both BiSrCaCuO and YBaCuO. A simple anti-resonance in $Δ(E)$ accounts for the pronounced QP peaks in the density of states, at an energy $Δ_p$, and the dip feature at a higher energy, $E_{dip}$. Here we go a step further : our gap function is consistent with the ($T, p$) phase diagram, where $p$ is the carrier density. For large QP energies ($E >> Δ_p$), the total spectral gap is $Δ(E) \simeq Δ_p + Δ_ϕ$, where $Δ_ϕ$ is tied to the condensation energy. From the available data, a simple $p$-dependance of $Δ_p$ and $Δ_ϕ$ is found, in particular $Δ_ϕ(p) \simeq 2.3 k_B T_c(p)$. These two distinct energy scales of the superconducting state are interpreted by comparing with the normal and pseudogap states. The various forms of the QP density of states, as well as the spectral function $A(k,E)$, are discussed.

description: This doctoral thesis deals with the development of a complete three-dimensional, finite-difference time-domain numerical scheme in the framework of acoustic propagation and scattering. The basic laws of scalar acoustic field propagation are studied and the most important factors of losses in acoustic energy are introduced. The need for a reliable absorbing boundary condition for the proper termination of the implementation of the generalized perfectly matched layer which is able to perform for the both lossless and lossy media. Moreover, the comparison of the numerical results with the respective exact analytical solutions of selected problems verified the great effectiveness of the suggested absorption technique. The extension to more complicated systems of guided sound waves in ducts and rooms permitted the further evaluation of the method's competence
