Optimizing electrochemical and electroless methods toward the surface-specific modification of Au nanorods
Creators: name: Fisher, Elizabeth A.
Publisher: name: University of British Columbia
Year: 2017

description: The controlled modification of gold nanorods has important implications for their successful applications in a wide variety of fields. In this work, electrochemical and electroless methods for the surface-specific modification of gold were optimized with the aim of developing a site-specific strategy for the functionalization of gold nanorods. Electrochemistry and fluorescence microscopy techniques were used to investigate the surface-specific modification of alkanethiol-coated gold bead electrodes, which served as a macroscopic model system for the nanorods. 11-mercaptoundecanoic acid (MUA) was partially removed from the electrodes by reductive desorption and the uncovered regions were modified with a fluorophore-functionalized, thiolated DNA molecule. Single crystal gold bead electrodes were employed in order to study and optimize the modification methods on all crystallographic surfaces under identical conditions. Two methodologies for the surface-specific modification of gold bead electrodes were investigated. In the first, a potential was applied to the electrode using a potentiostat, and it was determined that the SAM could be reductively removed selectively from the Au{111} surfaces of the electrodes by a 5 minute electrochemical application of any potential from -0.75 V to -0.8 V vs. Ag|AgCl. In the second method, the electrode potential was set electrolessly by adding a strong reducing agent, sodium borohydride, to the electrolyte. In the absence of oxygen, it was found that the electroless MUA desorption closely resembled the results obtained electrochemically, and that Au{111}-selective modification of the gold bead electrode was achieved at potentials near -0.75 V vs. Ag|AgCl. The electroless modification strategy was then applied to MUA-stabilized gold nanorods. Preliminary results indicate that sodium borohydride successfully removes alkanethiol from gold nanorod surface, enabling them to be modified with thiolated, fluorophore-labelled DNA.

description: In this review we provide an organized summary of the theoretical and computational results which are available for polymers subject to spatial or topological constraints. Because of the interdisciplinary character of the topic, we provide an accessible, non-specialist introduction to the main topological concepts, polymer models, and theoretical/computational methods used to investigate dense and entangled polymer systems. The main body of our review deals with: (i) the effect that spatial confinement has on the equilibrium topological entanglement of one or more polymer chains and (ii) the metric and entropic properties of polymer chains with fixed topological state. These problems have important technological applications and implications for the life-sciences. Both aspects, especially the latter, are amply covered. A number of selected open problems are finally highlighted.

description: We perform high resolution ray-tracing simulations to investigate probability distribution functions (PDFs) of lensing convergence, shear, and magnification on distant sources up to the redshift of $z_s=20$. We pay particular attention to the shot noise effect in $N$-body simulations by explicitly showing how it affects the variance of the convergence. We show that the convergence and magnification PDFs are closely related with each other via the approximate relation $μ=(1-κ)^{-2}$, which can reproduce the behavior of PDFs surprisingly well up to the high magnification tail. The mean convergence measured in the source plane is found to be systematically negative, rather than zero as often assumed, and is correlated with the convergence variance. We provide simple analytical formulae for the PDFs, which reproduce simulated PDFs reasonably well for a wide range of redshifts and smoothing sizes. As explicit applications of our ray-tracing simulations, we examine the strong lensing probability and the magnification effects on the luminosity functions of distant galaxies and quasars.

Efficient feasibility checking in reverse clock auctions for radio spectrum

Publisher: name: University of British Columbia
Year: 2017

description: We investigate the problem of building a feasibility checker to repack stations in the reverse auction part of the FCC’s ongoing, multi-billion-dollar “incentive auction”. In this work, we describe the design of a feasibility checker, SATFC, that has been adopted by the FCC for use in the incentive auction. We also construct a reverse auction simulator both in order to evaluate SATFC and also to gain insight into how the performance of the feasibility checker impacts the overall cost and efficiency of the auction. Through running simulations that differ only in the feasibility checker used, we show that the feasibility checker has a significant impact on auction cost and efficiency.

description: The infrared divergence of the self-energy of a color charge is due to an enhancement of the long wavelength modes of the color Coulomb potential field. There are also long wavelength contributions to the QCD vacuum energy that are similarly enhanced. Vacuum modes of Hubble scale wavelengths may be affected in a cosmological setting and this can lead to a residual positive energy density of the form $H^dΛ_{\rm QCD}^{4-d}$. Lattice studies constrain $d$. If the dark energy takes this form then the universe is driven towards de Sitter expansion, and we briefly study this cosmology when $d$ is just slightly above unity.

description: In short‐fiber reinforced polymers, fatigue damage is typically characterized by measuring the dynamic stiffness and its degradation under cyclic loading. Computational homogenization methods may be used to characterize the fatigue behavior of the composite via numerical predictions. Such an approach may reduce the experimental effort significantly. In the previous works, the authors proposed an elastic fatigue damage model for predicting the relative stiffness degradation of short‐fiber reinforced materials. However, the absolute value of the dynamic stiffness within the first cycle showed deviations from the expected elastic material behavior. Thus, the effect of viscoelastic polymer behavior as well as different microstructure descriptors on the dynamic stiffness is studied in the work at hand.

description: We consider $L^{2}$-supercritical and $H^{1}$-subcritical focusing nonlinear Schrödinger equations. We introduce a subset $PW$ of $H^{1}(\mathbb{R}^{d})$ for $d\ge 1$, and investigate behavior of the solutions with initial data in this set. For this end, we divide $PW$ into two disjoint components $PW_{+}$ and $PW_{-}$. Then, it turns out that any solution starting from a datum in $PW_{+}$ behaves asymptotically free, and solution starting from a datum in $PW_{-}$ blows up or grows up, from which we find that the ground state has two unstable directions. We also investigate some properties of generic global and blowup solutions.

description: A műanyagok előállítása és felhasználása során reakció- és bomlástermékek képződhetnek. A reakció- és bomlástermékek nem szándékosan vannak jelen a műanyagban (nem szándékosan hozzáadott anyagok). A bag in box csomagolóanyagok alapszerkezete 3 funkcionális rétegből épül fel, amelyek az alábbiak: nyomtatott réteg, funkcionális záróréteg, hegedőréteg. Az egyes rétegek alapanyaga a műanyagok széles skálájának megfelelően sokféle lehet. Ezen csomagolóanyagok további sajátossága, hogy a legkisebb falvastagsággal rendelkező rétegek kombinációjaként gyárthatók. Ebből adódik, hogy kioldódásképes alkotó komponenseik, a hátramaradt monomerek, adalékanyagok, a gyártástechnológiával összefüggő maradék oldószerek és melléktermékeik a vékony rétegekből, illetve azokon keresztül diffúzió útján könnyen áthatolva a tárolt anyaggal érintkezhetnek és abban oldódhatnak. A projekt eredményeképpen kifejlesztésre kerül egy folyadékok szállítására alkalmas „bag-in-box” termékpaletta gyártásterve. A fejlesztés célja azoknak a műanyagoknak a kutatása és kikísérletezése, melyek nem adják át ízüket és illatukat a tárolt folyadékoknak, illetve a hosszú szállítási folyamatok során hatékonyan megvédik a folyadékokat a minőségromlástól. Az egyik fontos részeredmény azoknak a tömeg és műszaki műanyagoknak az összegyűjtése volt, amelyek a fennálló problémára megoldást jelenthetnek, majd közülük a további kísérletezésre alkalmas további 3 műanyag kiválasztása történt meg. A kiválasztott 3 műanyaggal szemben alapkövetelmény, hogy minél alacsonyabb legyen a kioldódás, a tárolt folyadék ne vegye át a műanyag ízét, illatát. A projekt következő részeredménye, hogy a kiválasztott 3 műanyag mechanikai tulajdonságainak tesztelése, fény- és uv védelmi és sterilizálhatósági vizsgálatai, korábban nem feltételezett problémák feltárása és megoldása alapján kiválasztásra kerülhessen egy hegeszthető, fény- és uv védő réteggel rendelkező, sterilizálható anyagszerkezet.  A harmadik részeredmény – és egyben a projekt végeredményének – elérése érdekében a kiválasztott anyagszerkezet méretoptimalizása révén kidolgozásra kerül egy gyártásterv, ami alapján 1-5-10-20-100-200 literes, folyadékok tárolására és szállítására alkalmas „bag-in-box” termékek állíthatók elő. Az előállítható különböző méretű termékek újdonsága, hogy alkalmazásával a folyadékok szállítása gazdaságosabban, költséghatékonyabb formában valósulhat meg, a csomagolóanyagok üresen történő szállítás esetében ugyanis a dobozok, és maga a „bag-in-box is összehajthatók, így jelentős hely kapacitást spórolva a szállító cégeknek, főleg a jelenleg alkalmazott konténerekkel/palackokkal szemben.

description: We use the entropy production variational method to associate a one particle distribution function to the assumed known energy-momentum and entropy currents describing a relativistic conformal fluid. Assuming a simple form for the collision operator we find this one particle distribution function explicitly, and show that this method of linking the hydro and kinetic description is a non trivial generalization of Grad's ansatz. The resulting constitutive relations are the same as in the conformal dissipative type theories discussed in J. Peralta-Ramos and E. Calzetta, Phys. Rev. D {\bfseries 80}, 126002 (2009). Our results may prove useful in the description of freeze-out in ultrarelativistic heavy-ion collisions.

description: We study the implementation of global $SO(4)\sim SU(2)_L\otimes SU(2)_R$ symmetry in general potentials with N-Higgs-doublets in order to obtain models with custodial $SO(3)_C$ symmetry. We conclude that any implementation of the custodial SO(4) symmetry is equivalent, by a basis transformation, to a canonical one if $SU(2)_L$ is the gauge factor, $U(1)_Y$ is embedded in $SU(2)_R$ and we require $N$ copies of the doublet representation of $SU(2)_R$. The invariance by SO(4) automatically leads to a CP invariant potential and the basis of the canonical implementation of SO(4) is aligned to a basis where CP-symmetry acts in the standard fashion. We show different but equivalent implementations for the 2HDM, including an implementation not previously considered.

Le régime juridique de lutte contre le blanchiment des capitaux par les banques commerciales en Droit positif Congolais

description: Au cours des vingt dernières années, des régimes de lutte contre le blanchiment de capitaux ont vu le jour partout dans le monde. Destinés à enrayer le blanchiment des recettes des infractions préalables ou sous-jacentes que constituent le trafic de drogue, la fraude et la corruption, ces systèmes optimisent la détection de comportements illicites, la répression des malfaiteurs et le recouvrement des capitaux illicites. Ils sont donc vecteurs de prévention de la corruption. Ces activités délictuelles lucratives n’existaient pas, il n’y aurait pas non plus de blanchiment d’argent. Le lien étroit entre l’infraction pénale qui génère des revenus et le blanchiment de ces revenus fait qu’il est très difficile de séparer le blanchiment de l’infraction sous-jacente, même si, au regard de la loi, les deux choses sont distinctes. Le blanchiment de capitaux est une composante essentielle de tout acte délictueux lucratif dans la mesure où, sans blanchiment, le crime ne paie pas. La prise de conscience de la RDC s’est manifestée par l’élaboration et la mise en place des cadres juridiques et des structures appropriées en vue, d’une part, d’éviter l’expansion de ces phénomènes et, d’autre part, d’aboutir à leur éradication.

description: The differential cross section for the inclusive production of isolated prompt photons has been measured as a function of the photon transverse energy E_T-gamma in pp collisions at sqrt(s)=7 TeV using data recorded by the CMS detector at the LHC. The data sample corresponds to an integrated luminosity of 2.9 inverse picobarns. Photons are required to have a pseudorapidity |eta_gamma|<1.45 and E_T-gamma > 21 GeV, covering the kinematic region 0.006 < x_T < 0.086. The measured cross section is found to be in agreement with next-to-leading-order perturbative QCD calculations.

description: Boron nuclide and tritium projectile interactions are considerable in terms of nuclear energy systems. This study aims to investigate the realization of the nuclear fusion reactions of the bombardment of boron nuclei with tritium. In addition, the 8B(t,*), 9B(t,*), and 10B(t,*) reactions have focused on the use of the resulting product particles in nuclear technology applications, particularly in nuclear medicine applications, in terms of energy and number. Tritium-induced reactions from boron isotopes (8B, 9B, and 10B) at 50 and 100 MeV were modeled by the GEANT4 and EMPIRE Monte Carlo codes. Gamma, alpha, tritium, deuteron, proton, and neutron emission spectra (GEANT4-10.3) were obtained, and cross sections per energy (EMPIRE-3.2-MALTA) were calculated. Fusion cross sections and 6Li and 7Li production cross sections, which are critical in thermonuclear fusion reactors as basic fusion reactions, are discussed based on the 8B(t,*), 9B(t,*), and 10B(t,*) reactions.

description: The electromagnetic nucleon form-factors data are studied with artificial feed forward neural networks. As a result the unbiased model-independent form-factor parametrizations are evaluated together with uncertainties. The Bayesian approach for the neural networks is adapted for chi2 error-like function and applied to the data analysis. The sequence of the feed forward neural networks with one hidden layer of units is considered. The given neural network represents a particular form-factor parametrization. The so-called evidence (the measure of how much the data favor given statistical model) is computed with the Bayesian framework and it is used to determine the best form factor parametrization.

These are tree languages definable by a first-order formula whose quantifier prefix is forall exists, and simultaneously by a first-order formula whose quantifier prefix is . For the quantifier free part we consider two signatures, either the descendant relation alone or together with the lexicographical order relation on nodes. We provide an effective characterization of tree and forest languages definable in Δ_2 . This characterization is in terms of algebraic equations. Over words, the class of word languages definable in Δ_2 forms a robust class, which was given an effective algebraic characterization by Pin and Weil.
Simulating the evolution of consonant inventories
Creators: name: Mackie, James Scott
Publisher: name: University of British Columbia
Year: 2017

description: A major question in phonology concerns the role of historical changes in shaping the typology of languages. This dissertation explores the effect of sound change on consonant inventories. Historical reconstruction is mainly done by comparing cognate words across languages, making it difficult to track how inventories change specifically. Additionally, few languages have historical written records that can be directly examined. For this dissertation, the main research tool is computer simulation, using bespoke software called PyILM, which is based on the Iterated Learning Model (Kirby 2011, Smith et al. 2003). This allows for the simulation of sound change from arbitrary starting points, controlling for a multitude of variables. PyILM is an agent-based model, where a 'speaking' agent transmits a set of words to a 'listening' agent. The speaking agent is then removed, the learner becomes the speaker, and a new learner is introduced. The cycle repeats any number of times, roughly simulating the transmission of language over many generations. Sound change in a simulation is due to channel bias (Moreton 2008), the result of which is that agents occasionally misinterpret some aspect of speech, and internalize sound categories that differ from the previous generation (Ohala 1981, Blevins 2004). Three typological generalizations are examined, none of which have previously been studied from an evolutionary perspective: (1) The total number of consonants in a language. This is shown to be related to syllable structure, such that languages with simple syllables develop smaller inventories than languages with complex syllables. This mirrors a positive correlation between inventory size and syllable structure in natural languages, as reported by Maddieson (2007). (2) The correlation reported by Lindblom and Maddieson (1988) between the size of an inventory and the complexity of its segments. This effect emerges in simulations when context-free changes are introduced, since these changes produce similar outcomes in inventories of all sizes. (3) Feature economy (Clements 2003), which refers to the way that consonants within a language tend to make use of a minimal number of distinctive features. Economy emerges over time when sound changes take scope over classes of sounds, rather than targeting individual sounds.

description: Dans cet article nous discutons la possibilité d'utiliser la sociologie pour renforcer l'efficacité de l'usage éducatif des sciences de l'éducation. Nous proposons que certains usages de la sociologie servent à construire la transition nécessaire entre les sciences sociales et les sciences de l'éducation. Notre engagement, en tant qu'enseignants et gestionnaires, dans la conception et la mise en œuvre des programmes d'études des diplômes en éducation infantile et en enseignement primaire et du master en enseignement secondaire, nous a permis d'agir dans une situation qui exigeait une réflexion sur la nécessaire action conjointe des deux types de sciences. Nous avons modélisé le système complexe d'action éducative utilisé dans la formation initiale des futurs enseignants à l'Université de Valence, en nous basant sur une analyse des relations entre les différents usages de la pratique sociologique comme pratique d'enseignement. Pour cela, nous décrivons tout d'abord le contexte historique et social de la mise en place de ces nouveaux diplômes. Ensuite, nous expliquons le processus critique-pratique mis en œuvre. Nous concluons en objectivant les fondements épistémologiques et les règles méthodologiques qui ont guidé notre action. In this paper we argue about the possibility of using sociology to reinforce the effectiveness of the educational use of educational sciences. We propose that certain uses of sociology serve to build the necessary transition between the social sciences and the educational sciences. Our commitment, asteachers and managers, in the design and implementation of the curricula of the Bachelor's degree in early childhood and primary education and of the Master's degree in secondary education, has allowed us to act in a situation that required reflection on the necessary joint action of both types of sciences. We modeled the complex system of educational action used in the initial training of future teachers and professors at the University of Valencia, based on an analysis of the relationships between different uses of sociological practice as a teaching practice. To do this we describe, first, the historical and social context of the implementation of these new degrees. Then, we explain the critical-practical process carried out. We conclude by objectifying the epistemological foundations and the methodological rules that guided our action.

description: Um eine porositätsbedingte Durchkohlung von pulvermetallurgisch erzeugten Bauteilen beim Einsatzhärten zu vermeiden, kann der Wärmebehandlung eine mechanische Oberflächenbehandlung vorangestellt werden. Dabei wird die offene Porosität in eine oberflächenverdichtete, gradiert poröse Randschicht überführt. Ein Aufkohlen dieser oberflächennah verdichteten Bauteile erfolgt dann nahezu unbeeinflusst von der Porosität, was die Einstellung eines definierten Kohlenstoffprofils ermöglicht.

description: The work described in the present thesis considers structural modelling of microbial rhodopsins, to better understand the relation between structural and spectroscopic properties. To achieve that, multi-scale approaches are required, that combine both classical and quantum-chemical ideas (QM/MM). Therefore, we build structural models, optimize their structure, and calculate their UV/vis and vibrational spectra to compare to experimental observations.
Learning at the University - conceptions of university teachers

Subjects: Conceptions of learning; superficial and deep conceptions; university teachers; higher education; phenomenographic approach

description: This study investigates the conceptions of university teachers linked to the initial formation of teachers about what it is to learn at the University. The qualitative phenomenographic study presented was carried out with ten university teachers with more than 15 years of professional activity at the University and with an average age of 52 years, nine of whom are female and one male. The results showed stability in the conceptions of learning compared to previous studies; two main macro categories have been identified: superficial conceptions and deep conceptions. Learning conceptions were also identified as a process and as the development of social skills. In summary, teachers expressed different meanings of learning, and it should be noted that learning emerged conceptualized in a multidimensional and multifaceted way. In this group of teachers, different ways of conceptualizing learning are found, so the results point to the coexistence in the same subject of several conceptions about what it is to learn, and not a hierarchical structure of the conceptions in which the reproductive or superficial conception appears as subordinate to the transformative or profound conception. The results point to an inter-correlated model as a better descriptor of teachers' thinking about the nature of learning given the plurality of conceptions.

description: High‐entropy alloys (HEAs) or complex concentrated alloys (CCAs) offer a huge research area for new material compositions and potential applications. Since the combination of several elements sometimes leads to unexpected and unpredictable material properties. In addition to the element combinations, the optimization of the element proportions in CCAs and HEAs is also a decisive factor in tailoring desired material properties. However, it is almost impossible to achieve the composition and characterization of CCAs and HEAs with a sufficient number of compositions by conventional experiments. Therefore, an optimized high‐throughput magnetron sputtering synthesis to fabricate a new HEA gradient layer of six elements is presented. With this approach, the compositional space of the HEA system CrMoNbTaVW can be studied in different subsections to determine the influence of the individual elements and their combinations on the structure, morphology, and physical properties (hardness and resistivity). It is found that the Cr‐, Ta‐, and W‐rich phases, which have a grain size of 10–11 nm, exhibit the hardest mechanical properties, whereas V‐, Ta‐, and Cr‐rich compounds exhibit the highest electrical resistivity. The combination of high‐throughput synthesis, automated analysis tools, and automated data interpretation enables rapid and time‐efficient characterization of the novel CrMoNbTaVW gradient film.

description: We study in this article the representation theory of a family of super algebras, called the \emph{super Yang-Mills algebras}, by exploiting the Kirillov orbit method \textit{à la Dixmier} for nilpotent super Lie algebras. These super algebras are a generalization of the so-called \emph{Yang-Mills algebras}, introduced by A. Connes and M. Dubois-Violette in \cite{CD02}, but in fact they appear as a "background independent" formulation of supersymmetric gauge theory considered in physics, in a similar way as Yang-Mills algebras do the same for the usual gauge theory. Our main result states that, under certain hypotheses, all Clifford-Weyl super algebras $\Cliff_{q}(k) \otimes A_{p}(k)$, for $p \geq 3$, or $p = 2$ and $q \geq 2$, appear as a quotient of all super Yang-Mills algebras, for $n \geq 3$ and $s \geq 1$. This provides thus a family of representations of the super Yang-Mills algebras.
Teachers' Professional Core Competencies. Pedagogy and Educational Science in Swedish Teacher Education

description: Concepts of Pedagogy[1] about nurture/cultivation, learning and education originate from our ancient cultural heritage, but Pedagogy as an academic discipline was established in Sweden more than a hundred years ago to provide teacher education with a scientific basis. Education and its goals and means became essential societal issues in connection with industrialization, and Pedagogy, as a field of knowledge, has had, and still has, great significance in the shaping of society. Evidently, Pedagogy in the post-World War era has been put forward by various stakeholders to legitimize positions and actions in a field of tension between science, politics and education. This text presents the position and function of pedagogy in Swedish teacher education with emphasis on the ways in which the discipline has been treated in connection with the major teacher education reforms in Sweden that followed the founding of the nine- year compulsory school (Grundskolan) in 1962 up to today. Particular attention will be paid to the term "utbildningsvetenskap” (educational science), which was introduced in the 1990s and established at the turn of the millennium when an "educational science core" was prescribed in teacher education. At the same time, an Education Science Committee was formed within the Swedish Research Council to promote “research on learning, generation of knowledge, education and teaching”. Educational science arose as a way out of a sometimes tenses relationship between traditional pedagogy and a more modern, content-oriented, didactic research stream in order to strengthen teachers' scientific knowledge base and professional identity. Nevertheless, educational science remains imprecise, seeking an identity in relation to other more established pedagogical disciplines. [1] Pedagogy is used here as an equivalent to the Swedish term ‘Pedagogik’, which sometimes corresponds to English ‘education’ and French ‘éducation’ and sometimes not.

description: Les sciences de l’éducation sont en France une discipline universitaire relativement jeune qui a su conquérir une place importante dans la formation des enseignants. Pourtant cette place, si elle semble confortée depuis une trentaine d’année, n’en est pas moins sans cesse questionnée et remise en question par les différents acteurs impliqués dans la formation. Qu’il s’agisse des acteurs politiques qui tentent d’imposer leur réforme, des formateurs ou encore étudiants et stagiaires en formation, chacun d’entre eux, en fonction de ses propres points de vue ou de ses intérêts, tente de modeler la place et la forme que doivent prendre ces sciences dans les cursus de formation. Les enseignants chercheurs spécialistes de ces sciences observent alors avec un regard critique les injonctions ou recommandations qui leur sont faites d’adapter leurs contenus d’enseignements à des exigences de professionnalisation qu’ils jugent parfois réductrices. In France, educational sciences are a relatively young university discipline which has conquered an important place in the training of teachers. However, this place is regularly questioned by the different actors involved in the training. The political actors, the trainers or the students and trainees in training, tries to shape the place and the form that these sciences must take in the training courses according to their own points of view or their interests. Research professors specializing in these sciences observe with a critical eye the injunctions or recommendations that are made to them to adapt their teaching contents to requirements of professionalization that they sometimes consider to be reductive.

Are Educational Sciences useful in Teacher Education?

Subjects: Educational Sciences, Teacher Education, University, Students.

description: This paper deals with the question: are Educational Sciences (ES) useful in teacher education (TE)? The question draws its legitimacy from two facts. The first is of a historical nature: in Greece, ES found their institutional expression with the establishment of the University Departments of Pedagogy (UDP), whereby ES were integrated into initial TE. The second concerns the actual questioning of the value of ES in initial TE by students. The text attempts furthermore to investigate if the gap between theory and practice could be filled in the case of ES in the context of TE. To achieve this, we present an experimentation conducted in the European Educational Policy course of a UDP in the academic year 2019-2020. The experimentation seems to have been well received by the students, indicating that it is not impossible to fill this gap.
