description: The term "In Silico Trial" indicates the use of computer modelling and simulation to evaluate the safety and efficacy of a medical product, whether a drug, a medical device, a diagnostic product or an advanced therapy medicinal product. Predictive models are positioned as new methodologies for the development and the regulatory evaluation of medical products. New methodologies are qualified by regulators such as FDA and EMA through formal processes, where a first step is the definition of the Context of Use (CoU), which is a concise description of how the new methodology is intended to be used in the development and regulatory assessment process. As In Silico Trials are a disruptively innovative class of new methodologies, it is important to have a list of possible CoUs highlighting potential applications for the development of the relative regulatory science. This review paper presents the result of a consensus process that took place in the InSilicoWorld Community of Practice, an online forum for experts in in silico medicine. The experts involved identified 46 descriptions of possible CoUs which were organised into a candidate taxonomy of nine CoU categories. Examples of 31 CoUs were identified in the available literature; the remaining 15 should, for now, be considered speculative.

description: Στην παρούσα διδακτορική διατριβή μελετήθηκαν οι αντιδράσεις της υδρογόνωσης του CO^(2) και της αποσύνθεσης του C^(3)H^(8) σε ηλεκτροχημικούς αντιδραστήρες στερεών ηλεκτρολυτών αγωγών H^(+). Στην περίπτωση της υδρογόνωσης του CO^(2), το δισκίο του στερεού ηλεκτρολύτη ήταν ένα από τα περοβσκιτικά υλικά SrZr0.90Y0.10O^(3-a)(SZY) και SrCe0.95Yb^(0.005)O^(3-a)(SCY), ενώ τα ηλεκτρόδια εργασίας-καταλύτες που εξετάστηκαν ήταν Ca Pd & Ag σε μορφή πολυκρυσταλλικών υμενίων, τα οποία εναποτέθηκαν στην επιφάνεια του ηλεκτρολύτη. Σε όλες τις περιπτώσεις, η μοναδική αντίδραση που λαμβάνει χώρα είναι η RWGS(παραγωγή CO και Η2Ο). Αντίστοιχα, για την αντίδραση της αποσύνθεσης του C3H8 ο πρωτονιακός αγωγός ήταν ο SCY, ενώ τα ηλεκτρόδια εργασίας ήταν από Pt ή Pd
description: In the present thesis, the reactions of CO2 hydrogenation and the C3H8 decomposition were studied with the aid of solid-state proton conducting reactor-cells. In the case of H2 hydrogenation, the proton conductor was a perovskite-type disk of the form of either SrZr^(0.90)Y^(0.10)O^(3-a)(SZY) or SrCe^(0.95)Yb^(0.05)O^(3-a)(SCY) while the working electrodes-catalysts examined were Cu,Pd or Ag in the form of polycrystalline films, deposited on the surface of the electrolyte. The only reaction that took place was the RWGS, resulting in the production of CO2 and H2O. As far as the C3H8 decomposition reaction is concerned the proton-conducting disk was made of SCY while the working electrode was either Pt or Pd
Mediation as a form of social exchange
Creators: name: Floyd, Richard Heath
Publisher: name: University of British Columbia
Year: 2011

description: This thesis analyses the dynamics of mediation, as a dispute resolution process, from an Exchange Theory perspective. The argument is presented that the efficacy of the mediation process is a function of a triad of exchange relationships; between the disputants, and between the mediator and each of the disputants. The ability of the mediator to guide the progress of a negotiation towards settlement is determined by his or her success in manipulating the behaviours of the disputants. This is accomplished through a series of exchanges of sentiment, dispensed by the mediator, for behaviours by the disputants. The mediator seeks to gain the cooperation of the disputants by punishing or rewarding their behaviour. Rewards in the form of praise are provided in return for behaviours that the mediator perceives as conciliatory. Punishments in the form of critcism are imposed on behaviours that the mediator perceives as confrontational. Through this system of exchanges, the mediator is able to control the course of a negotiation, and ultimately, influence the probability of resolving a dispute.

An extension of Birkhoff--James orthogonality relations in semi-Hilbertian space operators

description: Let $\mathbb{B}(\mathcal{H})$ denote the $C^{\ast}$-algebra of all bounded linear operators on a Hilbert space $\big(\mathcal{H}, \langle\cdot, \cdot\rangle\big)$. Given a positive operator $A\in\B(\h)$, and a number $λ\in [0,1]$, a seminorm ${\|\cdot\|}_{(A,λ)}$ is defined on the set $\B_{A^{1/2}}(\h)$ of all operators in $\B(\h)$ having an $A^{1/2}$-adjoint. The seminorm ${\|\cdot\|}_{(A,λ)}$ is a combination of the sesquilinear form ${\langle \cdot, \cdot\rangle}_A$ and its induced seminorm ${\|\cdot\|}_A$. A characterization of Birkhoff--James orthogonality for operators with respect to the discussed seminorm is given. Moving $λ$ along the interval $[0,1]$, a wide spectrum of seminorms are obtained, having the $A$-numerical radius $w_A(\cdot)$ at the beginning (associated with $λ=0$) and the $A$-operator seminorm ${\|\cdot\|}_A$ at the end (associated with $λ=1$). Moreover, if $A=I$ the identity operator, the classical operator norm and numerical radius are obtained. Therefore, the results in this paper are significant extensions and generalizations of known results in this area.
Evolution of the cosmological mass function in a moving barrier model

Subjects: subject: Astrophysics (astro-ph)

description: I calculate the mass function evolution in a $Λ$CDM model by means of the excursion set model and an improved version of the barrier shape obtained in Del Popolo & Gambera (1998), which implicitly takes account of the total angular momentum acquired by the proto-structure during evolution and of a non-zero cosmological constant. I compare the result with Reed et al. (2003), who used a high resolution $Λ$CDM numerical simulation to calculate the mass function of dark matter haloes down to the scale of dwarf galaxies, back to a redshift of fifteen. I show that the mass function obtained in the present paper, gives similar predictions to the Sheth & Tormen mass function but it does not show the overprediction of extremely rare objects shown by the Sheth and Tormen mass function. The results confirm previous findings that the simulated halo mass function can be described solely by the variance of the mass distribution, and thus has no explicit redshift dependence.

description: We experimentally demonstrate that when three single photons transmit through two polarization channels, in a well-defined pre- and postselected ensemble, there are no two photons in the same polarization channel by weak-strength measurement, a counter-intuitive quantum counting effect called quantum pigeonhole paradox. We further show that this effect breaks down in second-order measurement. These results indicate the existence of quantum pigeonhole paradox and its operating regime.

description: The thesis involves the study of the dedicatory inscriptions concerning the founding, reconstruction, renovation or partial of the churches and other religious institutes in Asia Minor. The first part deals with the practice of donation and the institution of ktetoreia in the extensive region of Asia Minor throughout the Byzantine era. The donors and ktetors are classified according to their social class and are examined in relation with the socio-political conditions, the administrative structure and the general characteristics of Asia Minor world, the historical sources and the archaelogical testimonies. Issues with regard to the interpretation of the motives of donation, the statement of the gesture and the extent of sponsoring are also discussed. The text is supplemented by the catalogue, which includes 406 entries and aims in a comprehensive assembly of the majority of dedicatory inscriptions from Asia Minor

description: We present a measurement protocol for a flux qubit coupled to a dc-Superconducting QUantum Interference Device (SQUID), representative of any two-state system with a controllable coupling to an harmonic oscillator quadrature, which consists of two steps. First, the qubit state is imprinted onto the SQUID via a very short and strong interaction. We show that at the end of this step the qubit dephases completely, although the perturbation of the measured qubit observable during this step is weak. In the second step, information about the qubit is extracted by measuring the SQUID. This step can have arbitrarily long duration, since it no longer induces qubit errors.

Detailed expressions of the Seiberg -- Witten maps for the gauge parameters, gauge potentials and the field strengths have been worked out. Our results demonstrate that notwithstanding the introduction of more general noncommutative structure there is no first order correction, exactly as happens for a canonical (i.e. constant) noncommutativity.

description: The distribution of liquid water in ice-free clouds determines their radiative properties, a significant source of uncertainty in weather and climate models. Evaporation and turbulent mixing cause a cloud to display large variations in droplet-number density, but quite small variations in droplet size [Beals et al. (2015)]. Yet direct numerical simulations of the joint effect of evaporation and mixing near the cloud edge predict quite different behaviors, and it remains an open question how to reconcile these results with the experimental findings. To infer the history of mixing and evaporation from observational snapshots of droplets in clouds is challenging because clouds are transient systems. We formulated a statistical model that provides a reliable description of the evaporation-mixing process as seen in direct numerical simulations, and allows to infer important aspects of the history of observed droplet populations, highlighting the key mechanisms at work, and explaining the differences between observations and simulations.

description: Nonlinear magneto-optical Faraday rotation (NMOR) on the potassium D1 and D2 lines was used to study Zeeman relaxation rates in an antirelaxation paraffin-coated 3-cm diameter potassium vapor cell. Intrinsic Zeeman relaxation rates of $γ^{NMOR}/2π=2.0(6) {\rm Hz}$ were observed. The relatively small hyperfine intervals in potassium lead to significant differences in NMOR in potassium compared to rubidium and cesium. Using laser optical pumping, widths and frequency shifts were also determined for transitions between ground-state hyperfine sublevels of $^{39}$K atoms contained in the same paraffin-coated cell. The intrinsic hyperfine relaxation rate of $γ^{hf}_{expt}/2π= 10.6(7) $Hz and a shift of $-9.1(2) $Hz were observed. These results show that adiabatic relaxation gives only a small contribution to the overall hyperfine relaxation in the case of potassium, and the relaxation is dominated by other mechanisms similar to those observed in previous studies with rubidium.

description: Recently two interesting conjectures about the string S-matrix on AdS_5 x S^5 have been made. First, assuming the existence of a Hopf algebra symmetry Janik derived a functional equation for the dressing factor of the quantum string Bethe ansatz. Second, Hernandez and Lopez proposed an explicit form of 1/\sqrtλcorrection to the dressing factor. In this note we show that in the strong coupling expansion Janik's equation is solved by the dressing factor up to the order of its validity. This observation provides a strong evidence in favor of a conjectured Hopf algebra symmetry for strings in AdS_5 x S^5 as well as the perturbative string S-matrix.

description: Die vorliegende Masterthesis untersucht anhand von qualitativen Methoden im Rahmen eines Projektauftrages der Organisation «Qualifutura», inwiefern die Ausgestaltung ihres Angebots und ihres sozialarbeiterischen Handelns die Veränderungsmotivation ihrer Zielgruppe (Jugendliche und junge Erwachsene mit Mehrfachproblematiken) begünstigt. In einem ersten Schritt wird mittels einer Organisationsanalyse herausgearbeitet, welche Ziele Qualifutura verfolgt und welche Haltungen und theoretischen Annahmen für ihr sozialarbeiterisches Handeln und die Ausgestaltung des Angebots richtungsweisend sind. Auf der Basis einer Analyse von wissenschaftlicher Fachliteratur wird in einem zweiten Schritt heraus-gearbeitet, welche Kontextbedingungen, sozialarbeiterischen Haltungen und Techniken bezüglich der Förderung von Veränderungsmotivation bei der Adressat*innengruppe von Qualifutura als wirksam eingeschätzt werden. Vor diesem Hintergrund werden acht leitfadengestützte halbstrukturierte Einzelinterviews mit Adressat*innen von Qualifutura durchgeführt. Zugleich werden Einschätzungen der zuweisenden Stellen, welche die Adressat*innen oftmals über einen längeren Zeitraum betreuen, anhand einer schriftlichen Befragung abgeholt. Im Anschluss werden die Interviews und Befragungen inhaltsanalytisch ausgewertet, wobei überwiegend induktiv vorgegangen wird. In einer Synthese werden die Erkenntnisse aus der Datenanalyse anhand des herausgearbeiteten theoretischen Fachwissens reflektiert und bewertet. Zudem werden die Erkenntnisse auf die Organisations-analyse bezogen, sodass sie in einem für die Praxisorganisation zugänglichen Aussagezusammenhang stehen. In der Evaluation werden in Bezug auf Veränderungsmotivation überwiegend begünstigende, jedoch auch wenige erschwerende Faktoren in der Praxis von Qualifutura identifiziert. Als begünstigende Fak-toren werden die konsequente Adressat*innenorientierung innerhalb der Beziehungsgestaltung festgestellt sowie die Förderung von Selbstbestimmung in der Zusammenarbeit, die Steigerung des Selbstreflexionsvermögens, die gesteigerte Stabilität der Adressat*innen, die Individualisierung des Angebots und die pragmatische Herangehensweise an Problemlagen. Ein potentiell günstiger wie auch gleichzeitig hinderlicher Faktor wird im Einfluss der Peerbeziehungen identifiziert. Als erschwerende Bedingungen werden der tiefe Selbstwert und die niedrige Selbstwirksamkeitserwartung sowie eine alle Ebenen der Zusammenarbeit durchdringende Diffusität bezüglich Erwartungen, Ziele und Zuständigkeiten festgestellt.

description: In the modern search for life elsewhere in the Universe, we are broadly looking for the following: the planets similar to Earth - physical indicators of habitability, and the manifestation of life - the biological signatures. A biosignature is a measured parameter that has a high probability of being caused by the living organisms, either atmospheric gas species or some surface features. Therefore, the focus of a search is on a product or phenomena produced by the living systems, mostly by microorganisms as these are the most abundant on our planet like, say, methane. However, we may need to distinguish the terms `biosignature' and `bioindicator'. A biosignature is what living organisms produce - a bioproduct, while a bioindicator may be anything necessary for life as we know it, such as water or a rocky planet. Oxygen in this case is a double biomarker; first, it is a byproduct of oxygenic photosynthesis and, second, it is a signature of a complex life, because complex highly organized life requires high levels of oxygen. It is possible that there are other such bioindicators. For example, in the atmospheric compositions of terrestrial planets in our Solar System (including Titan), argon is one of the major constituents, moreover it was recently acknowledged to be a `biologically' active gas, exhibiting organprotective and neuroprotective properties, especially under hypoxic conditions. Here we propose that argon in the atmosphere of a rocky planet is a bioindicator of a highly organized life, provided that the planet is already deemed potentially habitable: with water, atmosphere, and of a certain age allowing for the complex life to evolve. We also delineate its possible detection methods.

description: The backreaction of nonlinear inhomogeneities to the cosmic expansion is analyzed in the framework of general relativity with a cosmological constant. By defining the spatially averaged matter energy density, we find that the cosmological constant induces a new type of backreaction whose equation of state is $p=-4/3 ρ$, where $ρ$ and $p$ are the effective energy density and effective pressure of the backreaction in the averaged Friedmann universe. However, the effective density is negative, and thus it decreases the acceleration caused by the cosmological constant.

description: Ion implantation of Fe and Mn into Al thin films was used for effective modification of Al superconductive properties. Critical temperature of the transition to superconducting state was found to decrease gradually with implanted Fe concentration. it was found that suppression by Mn implantation much stronger compared to Fe. At low concentrations of implanted ions, suppression of the critical temperature can be described with reasonable accuracy by existing models, while at concentrations above 0.1 at.% a pronounced discrepancy between the models and experiments is observed.

description: The Fermi-LAT DR1 and DR2 4FGL catalogues feature more than 5000 gamma-ray sources of which about one fourth are not associated with already known objects, and approximately one third are associated with blazars of uncertain nature. We perform a three-category classification of the 4FGL DR1 and DR2 sources independently, using an ensemble of Artificial Neural Networks (ANNs) to characterise them based on the likelihood of being a Pulsar (PSR), a BL Lac type blazar (BLL) or a Flat Spectrum Radio Quasar (FSRQ). We identify candidate PSR, BLL and FSRQ among the unassociated sources with approximate equipartition among the three categories and select ten classification outliers as potentially interesting for follow up studies.

description: Τα παιδιά με αποκλίνουσα συμπεριφορά παρουσιάζουν ιδαίτερα ψυχοκοινωνικά προβλήματα προσαρμογής. Ερωτήματα ανακύπτουν κατά πόσο η συμπεριφορά των παιδιών αυτών έχει αντίκτυπο στην κινητική τους ανάπτυξη, τη σχολική επίδοση, όπως και στην ίδια την ψυχοκοινωνική τους εξέλιξη. Στην έρευνα αυτή έλαβαν μέρος 319 μαθητές της Ε' και Στ' τάξης του Δημοτικού σχολείου(Μ.Ο.=11.2 έτη, Τ.Α.=79). Από την ανάλυση συσχέτισης προέκυψε ότι η αποκλίνουσα συμπεριφορά παρουσίασε θετική συσχέτιση με τις παραμέτρους της κινητικής αδεξιότητας και αρνητική συσχέτιση με τη σχολική επίδοση και τους περισσότερους παράγοντες του αυτοσυναισθήματος. Από την ανάλυση Mann Whitney διαπιστώθηκε ότι : α) τα παιδιά που παρουσιάζουν εσωτερικευμένη μορφή αποκλίνουσας συμπεριφοράς υστερούσαν στις παραμέτρους της κινητικής αδεξιότητας, ενώ τα παιδιά με εξωτερικευμένη μορφή σε ορισμένες περιπτώσεις είχαν καλύτερες β)τα παιδιά με αποκλίνουσα συμπεριφορά, εκτός την ομάδα με άγχος, ανησυχία, είχαν χαμηλότερες επιδόσεις στο σύνολο των μαθημάτων γ)τα παιδιά με εσωτερικευμένη μορφή αποκλίνουσας συμπεριφοράς παρουσίασαν χαμηλότερες τιμές στις παραμέτρους του αυτοσυναισθήματος που σχετίζονται με τις σχολικές και αθλητικές επιδόσεις, ενώ τα παιδιά με εξωτερικευμένη με τις παραμέτρους που σχετίζονται με την κοινωνική προσαρμογή. Από την ανάλυση παλινδρόμησης προέκυψε ότι ο σημαντικότερος παράγοντας πρόβλεψης είναι η ελλειματική προσοχή
description: Pupil with deviant behavior present special problems in phychosocial development. The stample of the study consisted of 319 pupil from the fiveth and sixth class of primacy school. According to correlation analysis it was revealed that there was a statistical positive correlation between the factors of deviant behavior and parameters of motor clumsiness and an inverse correlation with school achievement and most of factors of self-esteem. From Mann-Whitney U analysis it was revealed that a)children who performed internalized behavior were delayed to the parameters of the Motor clumsiness, whereas children with externalized form of deviant behavior except for group with tention-anxiety, performed lower achievements in the school performance c)children with ohychoemotional problems presented lower rates in the parameters of self-esteem, which are correlated to school and sport achievement. However, children with behavior problems demonstrated differences in the parameters of self-esteem related to social acceptance and socila relations. At the and according to regression analysis it was revealed that the most important predictor factor was the withdrawal with attention deficit

description: Background: Camptocormia is defined as forward flexion of the spine that manifests during walking and standing and disappears in recumbent position. The various etiologies include idiopathic Parkinson’s disease, multiple system atrophy, myopathies, degenerative joint disease, and drugs. Case Report: A 67-year-old diabetic female presented with bradykinesia and camptocormia that started 1 year prior to presentation. Evaluation revealed levosulpiride, a dopamine receptor blocker commonly used for dyspepsia, to be the culprit. Discussion: It is well known that dopamine receptor blockers cause parkinsonism and tardive syndromes. We report a rare and unusual presentation of camptocormia attributed to this commonly used gastrointestinal drug in the Asian population.

description: The rapidity densities in Au-Au collisions at center-of-mass energies 200 and 130 A GeV measured at Relativistic Heavy-Ion Collider by STAR and PHENIX collaborations are analyzed within the statistical hadronization model at chemical freeze-out. We find that the model can describe the experimental rapidity densities well. The corresponding chemical freeze-out parameters are determined and they are seen to be in agreement with what we expect from our previous analyzes at lower beam energies at AGS and SPS.

description: The doctoral thesis deals with the international tax treatment of partnerships. Its subject is application of double tax traties on partnerships. The specific problem of international partnerships is the determination of the personal scope of double tax treaties. The income qualification and the subsequent distribution of tax power between the contracting states will be determined accordingly. Special reference is made to the tax treatment of the income that a foreign partner earns from the participation in a greek partnership
The Robert Kroetsch alphabet book : sketches of a thesis
Creators: name: Fero, Alanna Carlene
Publisher: name: University of British Columbia
Year: 2011

description: Robert Kroetsch, a contemporary Canadian novelist, poet, and critic, can often be found investigating systems of ordering: he examines their contrasting characteristics of symmetry and arbitrariness; necessity and inanity; their potential to be both banal and surprising. My thesis on Robert Kroetsch's aesthetic comprises twenty-six chapters, each corresponding to a letter of the alphabet. Kroetsch's work has increasingly come to be affiliated with the "language poets"; his absorption with system invariably leads him back to the nature of the linguistic sign, and the possibilities and limitations of significance. For example, both Kroetsch's most recent novel, What the Crow Said, and "The Sad Phoenician," a long poem in which he reflects upon his identity as a writer, focus on the alphabet. In Crow, the nature of the alphabet as a paradoxically enabling and confining structure is explored thematically; in "Phoenician," the alphabetization of stanzas forms the enabling and confining structure of the text. Thus, the form of my thesis responds to those of Kroetsch; it is a form which becomes, finally, a thesis in itself.

We also show that there is a finite-time algorithm that computes, given an element of a Garside group, its stable super summit set.

description: The variance of the number of lattice points inside the dilated bounded set rD with random position in R^d has asymptotics r^(d-1) if the rotational quadratic average of the modulus of the Fourier transform of the set is O(r^(-d-1)). The asymptotics follows from a Wiener's Tauberian theorem.
A mapping space Odyssey: characterising the statistical and metric properties of reduced representations of macromolecules

description: Simplified representations of macromolecules help in rationalising and understanding the outcome of atomistic simulations, and serve to the construction of effective, coarse-grained models. The number and distribution of coarse-grained sites bears a strict relation with the amount of information conveyed by the representation and the accuracy of the associated effective model; in this work, we investigate this relationship from the very basics: specifically, we propose a rigorous notion of scalar product among mappings, which implies a distance and a metric space of simplified representations. Making use of a Wang-Landau enhanced sampling algorithm, we exhaustively explore the space of mappings, quantifying their qualitative features in terms of their squared norm and relating them with thermodynamical properties of the underlying macromolecule. A one-to-one correspondence with an interacting lattice gas on a finite volume leads to the emergence of discontinuous phase transitions in mapping space that mark the boundaries between qualitatively different representations of the same molecule.
