description: Il criterio di efficienza é ormai considerato uno dei principali parametri di valutazione delle operazioni di concentrazione nell’ambito dell’applicazione della disciplina antitrust, sia dalla prassi degli organismi deputati a esercitare tale funzione sia da parte della letteratura. Nel momento in cui operazioni di concentrazione vengono poste in essere da due istituti di credito, lo stesso criterio può tuttavia entrare in gioco anche nell’esercizio della funzione di vigilanza bancaria. 
Il presente lavoro si propone di verificare, con riferimento all’ordinamento italiano, se e in quali termini il criterio di efficienza, utilizzato con frequenza crescente in ambito antitrust, possa essere impiegato anche nell’esercizio della funzione di vigilanza bancaria, e ciò alla luce dell’interpretazione del concetto di efficienza elaborata da Banca d’Italia sia in sede di adozione delle Istruzioni di vigilanza, sia nell’esercizio concreto della vigilanza generalmente intesa. 
In ragione del risultato di questa verifica, e sempre in una prospettiva di efficienza, nella parte finale del lavoro viene analizzato il nuovo riparto di competenze in materia di valutazione delle concentrazioni bancarie a fini antitrust fissato dalla legge 266/2005, così come recentemente modificata dal D. Lgs. 29 dicembre 2006 n. 303 (che, lo ricordiamo, ha attribuito alla Banca d’Italia la possibilità di richiedere all’Autorità Garante della Concorrenza e del Mercato di autorizzare operazioni di concentrazione tra banche o gruppi bancari “per esigenze di stabilità di uno o più dei soggetti coinvolti”), con particolare attenzione alla capacità dell’attuale modello  di ottimizzare l'intervento pubblico in un ambito, quello appena definito, in cui due funzioni pubbliche, di regolazione della concorrenza da un lato e di vigilanza da altro lato, tendono a sovrapporsi, e, secondo alcuni, a contrapporsi.

description: André Guillou, a cui va il merito di aver sistematicamente accorpato ed esaminato nel suo Recueil des inscriptions grecques médiévales d’Italie la maggior parte delle iscrizioni che si riferiscono al periodo della dominazione bizantina o più propriamente roméa d’Italia, ha offerto attraverso questo ampio corpus un apporto fondamentale all’epigrafia delle aree provinciali dell’Impero insieme alle raccolte di iscrizioni e ai contributi pubblicati nelle riviste specialistiche che consentono di applicare ai reperti epigrafici un’indagine sistematica sul piano comparativo. Il presente studio, comprendente un’indagine di tipo storico e filologico, nonché un’analisi grafica, si rivolge ad alcune significative testimonianze epigrafiche dei ceti dirigenti dell’amministrazione bizantina d’Italia, in un periodo compreso fra l’età di Eraclio (610-641) a quella di Basilio II (976-1025), che hanno suscitato un particolare interesse per l’elevato apporto ideologico-politico e per la loro dislocazione territoriale, che ci proietta nell’ampio panorama storico e culturale dei contesti geopolitici dell’Esarcato, dei Ducati e del Catepanato d’Italia. Tali testimonianze unitamente alle tracce di munificenza lasciate dai funzionari di rango più o meno elevato dell’amministrazione imperiale contribuiscono a chiarire più di un aspetto della storia socio-culturale dell’Occidente bizantino.

description: Da Gerste zu den wichtigsten Getreidesorten weltweit zählt, besteht ein großes Interesse, Faktoren, die die Qualität des Samens und der Stresstoleranz der Pflanze beeinflussen, zu bestimmen. Das Ziel der vorliegenden Arbeit lag darin, Proteinnetzwerke im sich entwickelnden Gerstensamen und in der Blattepidermis zu detektieren. Die molekularen Funktionen der Blattepidermis konnten erfolgreich mittels Proteinanalysen aufgedeckt werden. Eine Vielzahl der detektierten Proteine stand im Zusammenhang mit Krankheits- und Stressabwehr, was Hinweise auf eine mögliche Schutzfunktion der Blattepidermis gibt. Die gemessenen Unterschiede zwischen Mesophyll- und Epidermisgewebe bezüglich der Metabolitverteilung weisen auf eine Akkumulation von Glukose und Fruktose in der Epidermis. Zusätzlich wurden die biochemischen Prozesse während der Gerstensamenentwicklung mittels Proteinanalytik genauer betrachtet. Die Ergebnisse zeigten eine entwicklungsabhängige Abundanz der Proteine, wobei radikalfangende Enzyme, Histone, Proteinsynthese bezogene und Photosynthese bezogene Proteine eine höhere Abundanz in der mittleren Phase der Entwicklung zeigten. Speicherproteine und Proteine, die in die Festlegung der Samentextur und in den Schutz von Speicherreserven involviert sind, waren in der späten Phase der Samenentwicklung höher abundant. Weiterhin wurden Proteine in der Nucellaren Projektion und den endospermalen Transferzellen analysiert. Beide Gewebe sind wichtig für den Nährstofftransport vom maternalen zum filialen Gewebe und die Mehrheit der detektierten Proteine ist in Translationsprozesse und die Verarbeitung und Synthese von Proteinen involviert. Zusätzlich konnten gewebespezifische Proteine identifiziert werden.

description: Il testo è stato elaborato nell’ambito di un progetto dal titolo “Dalle biblioteche e gli archivi alla divulgazione in ambito universitario: il diritto d’autore nello studio, nella ricerca e nella didattica” congiuntamente condotto dal Centro E-learning Ateneo di Bologna (CELAB) dell’Alma Mater Studiorum – Università di Bologna e dalla Fondazione Istituto Gramsci Emilia-Romagna. 
Esso si prefigge come obiettivo di divulgare tra i protagonisti del mondo accademico i principi e le norme fondamentali in materia di diritto d’autore, in modo che questi possano avere a disposizione uno strumento di agevole lettura che consenta loro, superando le complessità tipiche dei testi giuridici specialistici, di trovare risposte (e prima ancora di porsi le opportune domande) in relazione ai dubbi che quotidianamente si affacciano in chi – soprattutto non essendo un giurista – crei, utilizzi o diffonda opere dell’ingegno per finalità di studio, di didattica o di ricerca.
Il testo si rivolge dunque, in particolare, al personale docente e ricercatore che opera nell’Università, al personale non docente la cui attività, per ua stessa natura, finisce con l’intersecare normalmente le tematiche relative al diritto d’autore (come bibliotecari e archivisti) e, infine, a coloro che dell’Università sono gli utenti, ovvero gli studenti. 
Trattandosi di un’opera per “non addetti ai lavori ”, si è cercato di utilizzare nel corso della redazione un linguaggio piano e ricco di esempi, così da agevolare la comprensione della rilevanza pratica delle norme prese in esame. A questo fine si è proceduto per cerchi concentrici, illustrando nel primo capitolo i principi generali che regolano la materia e contribuendo, nel secondo capitolo, a chiarire come questi siano stati influenzati (e in alcuni casi stravolti) dalla rivoluzione digitale. Nel terzo capitolo, infine, l’attenzione è stata focalizzata sulle ipotesi di più frequente occorrenza in ambito accademico, applicando a taluni casi particolari i principi generali illustrati nei primi due capitoli.

description: Percolation on a one-dimensional lattice and fractals such as the Sierpinski gasket is typically considered to be trivial because they percolate only at full bond density. By dressing up such lattices with small-world bonds, a novel percolation transition with explosive cluster growth can emerge at a nontrivial critical point. There, the usual order parameter, describing the probability of any node to be part of the largest cluster, jumps instantly to a finite value. Here, we provide a simple example of this transition in form of a small-world network consisting of a one-dimensional lattice combined with a hierarchy of long-range bonds that reveals many features of the transition in a mathematically rigorous manner.

description: In den Zellmembranen einiger extremophiler Archaebakterienarten wurden recht ungewöhnliche Lipide entdeckt. Diese Tetraetherlipide bestehen aus zwei hydrophilen Kopfgruppen, die durch ein oder zwei Alkylketten verbunden sind, und gehören zur Stoffgruppe der Bolaamphiphile. Die Tetraetherlipide spielen eine wichtige Rolle für die Stabilität, Fluidität und Permeabilität der Zellmembran. Die Regulierung des Verhältnisses von Methylverzweigungen zu Cyclopentanringen in den Alkylketten erlaubt die Anpassung an die vorherrschenden Umweltbedingungen. Von pharmazeutischen Interesse sind die Liposomenbildungstendenz sowie die große chemische, enzymatische und thermische Stabilität, die sehr wünschenswerte Eigenschaften eines Arzneistoffträgersystems darstellen. Im Rahmen der vorliegenden Arbeit wurden eine Reihe symmetrischer und unsymmetrischer Bolaamphiphile synthetisiert. Sowohl der Einfluss vereinzelter Methylverzweigungen an definierten Positionen als auch der Einfluss der Stereochemie der entsprechenden Alkylketten auf das lyotrope und thermotrope Phasenverhalten wurden untersucht. Dafür wurden verschiedene physikochemische Untersuchungen, wie zum Beispiel Differential Scanning Calorimetry (DSC), Transmissions- (TEM) oder Gefrierbruchelektronenmikroskopie (FFEM) durchgeführt. Die dargestellten Lipide wurden als liposomale Transportsysteme für Nukleinsäuren und Arzneistoffe untersucht. Insbesondere ein unsymmetrisches, methylverzweigtes Bolaamphiphil bewirkte in Mischung mit Cholesterol und Ei-Phosphatidylcholin eine gesteigerte Liposomenstabiltät gegenüber künstlichen Verdauungsmedien.

description: In their paper "1-skeleta, Betti numbers, and equivariant cohomology" Guillemin and Zara described some beautiful constructions enabling them to use Morse theory on a certain class 1-skeleta including 1-skeleta of simple polytopes. In this paper we extend some of the notions and constructions from that paper to a larger class of 1-skeleta that includes 1-skeleta of projected simple polytopes. As an application of these ideas we prove a lifting result for 1-skeleta, which yields a characterization of 1-skeleta coming from projected simple polytopes.

description: Curcumin, ein Inhaltsstoff aus Gelbwurz (Curcuma longa L.), ist seit einigen Jahren im Fokus der biomedizinischen Forschung. Neben seiner antioxidativen und antiinflammatorischen Wirkkomponente zeigt Curcumin auch vielversprechende Wirkungen bei der Therapie von Krebserkrankungen. Die meisten der beschriebenen Effekte wurden jedoch nur in in vitro Experimenten nachgewiesen und derzeit gibt es nur unzureichende Daten über die Wirkung von Curcumin in vivo. Ein Grund dafür ist die geringe orale Bioverfügbarkeit von Curcumin. Das Ziel dieser Arbeit war es eine Formulierung für die orale Applikation von Curcumin zu entwickeln. Die Substanz wurde dafür in Lipidnanopartikel eingearbeitet, die mittels Hochdruckhomogenisation hergestellt wurden. Die hergestellten Formulierungen wurden hinsichtlich ihrer Partikelgröße und der physikochemischen Eigenschaften des Lipides und des inkorporierten Curcumins untersucht. Des Weiteren wurden ein in vitro Verdau-Assay und Freisetzungsversuche durchgeführt, um zu simulieren wie sich die Partikel nach oraler Applikation verhalten.
description: The active ingredient of turmeric (Curcuma longa L.), Curcumin, has been in the focus of biomedical research since many years. Besides its antioxidant and anti-inflammatory activity, Curcumin has also shown promising potential against cancerous diseases. However, many effects were only demonstrated by in vitro experiments and only few data of in vivo experiments exist. A major reason for the insufficient in vivo data is the low oral bioavailability of Curcumin. The aim of the present work was the development of a formulation for the oral delivery of Curcumin. The drug was incorporated into lipid nanoparticles, which were produced by high pressure homogenization. The produced particles were characterized with regard to their particle size and to the physicochemical properties of the lipid and the incorporated Curcumin. Furthermore, an in vitro digestion assay and release experiments were conducted to simulate the fate of the lipid and the drug during oral ingestion.

description: We prove that nonsmooth quasilinear parabolic systems admit a local, strongly differentiable (with respect to time) solution in Lp over a bounded three-dimensional polyhedral space domain. The proof rests essentially on new elliptic regularity results for polyhedral Laplace interface problems with anisotropic materials. These results are based on sharp pointwise estimates for Green's function, which are also of independent interest. To treat the nonlinear problem, we then apply a classical theorem of Sobolevskii for abstract parabolic equations and recently obtained resolvent estimates for elliptic operators and interpolation results. As applications we have in mind primarily reaction diffusion systems. The treatment of such equations in an Lp context seems to be new and allows (by Gauss' theorem) to define properly the normal component of currents across the boundary.

description: Schur-Weyl duality is a powerful tool in representation theory which has many applications to quantum information theory. We provide a generalization of this duality and demonstrate some of its applications. In particular, we use it to develop a general framework for the study of a family of quantum estimation problems wherein one is given n copies of an unknown quantum state according to some prior and the goal is to estimate certain parameters of the given state. In particular, we are interested to know whether collective measurements are useful and if so to find an upper bound on the amount of entanglement which is required to achieve the optimal estimation. In the case of pure states, we show that commutativity of the set of observables that define the estimation problem implies the sufficiency of unentangled measurements.

description: Die molekulare Organisation von der SC interzellulären Lipidmatrix und ihre Barrierefunktion werden lebhaft diskutiert. In den ersten Studien über die SC-Organisation und Funktion wurden native, aus der Säugerhaut isolierte SC-Membranen eingesetzt. Die Komplexität solcher Systeme begrenzt die Möglichkeit, die Unterschiede in der SC-Lipidzusammensetzung auf Veränderungen in der molekularen Organisation und Funktion des SC zu beziehen. Daher wurden definierte künstliche SC-Lipidmodellmembranen, die u.a. Cer [AP] und Cer [EOS] enthielten, im Rahmen der vorliegenden Arbeit verwendet. Der wichtigste Vorteil solcher Systeme scheint zu sein, dass ihre Zusammensetzung systematisch modifiziert werden kann. Das Hauptziel der vorliegenden Arbeit war es, einen besseren Einblick in die Beziehung der interzellulären Lipidmatrixzusammensetzung/Organisation zur Barrierefunktion zu bekommen, basierend auf den Diffusions- und Permeationsstudien von Harnstoff, Koffein und Diclofenac-Natrium.
description: The molecular organization of the SC intercellular lipid matrix and its barrier function are still vigorously discussed. In the first studies on the SC organization and function, native SC membranes isolated from the mammalian skin were used. However, the complexity of such systems limits the possibility to relate differences in the SC lipid composition to changes in the SC molecular organization and function. Therefore, well-defined artificial SC lipid model membranes composed of i.a. Cer [AP] and Cer [EOS] were used within the framework of this thesis. The most important advantage of such systems seems to be that their composition can be systematically modified. The main objective of this thesis was to get a better insight into the SC intercellular lipid matrix composition/organization–barrier function relationship based on the diffusion and permeation studies of urea, caffeine and diclofenac sodium.

description: Propranolol HCl Pellets wurden mit Polymermischungen aus Polyvinylacetat und Polyethylenglycol-Polyvinylalkohol überzogen. Im Rahmen der vorliegen Arbeit wurden der Einfluss der Formulierung und der Coatingbedingungen auf die Propranolol HCl Freisetzung aus PVAc/PVA-PEG überzogenen Pellets untersucht. Außerdem wurde die Lagerungsstabilität analysiert. Mittels ESEM konnten morphologische Veränderungen des Polymerfilms, die durch Curing oder Lagerungsbedingungen hervorgerufen wurden, untersucht werden. Ein weiterer Aspekt dieser Arbeit war es, den zugrundeliegenden Freisetzungsmechanismus PVAc/PVA-PEG überzogener Propranolol HCl Pellets, die osmotisch aktive Agenzien enthalten, zu untersuchen. Quellungsexperimente und NMR Relaxometrie zeigten einen schnellen Wassereinstrom durch die Polymermembran in die Pellets. Diese Ergebnisse wurden durch ESR Experimente bestätigt. Die Wirkstofffreisetzung wird durch die Coatingzusammensetzung sowie durch osmotische Substanzen im Pelletkern gesteuert.
description: Propranolol HCl pellets were coated with polymer blends of poly(vinyl acetate) and poly(vinyl alcohol)-poly(ethylene glycol) copolymer. Within the present thesis the impact of formulation modifications and coating conditions on the Propranolol HCl release from PVAc/PVA-PEG coated pellets were investigated. In addition, stability issues were examined. ESEM experiments allowed to analyze morphological changes of the polymer film coat induced by curing or storage conditions. Another main aspect of this work was to elucidate the underlying drug release mechanism of PVAc/PVA-PEG coated Propranolol HCl pellets comprising of osmotically active ingredients. Swelling experiments and NMR relaxometry revealed a fast water diffusion through the polymer membrane into the pellet cores. These results were underlined by EPR experiments. The drug liberation was found to be controlled by the coating composition and by osmotically active ingredients within the pellet core.

description: Galaxy clustering data can be used to measure the cosmic expansion history H(z), the angular-diameter distance D_A(z), and the linear redshift-space distortion parameter beta(z). Here we present a method for using effective multipoles of the galaxy two-point correlation function (ξ_0(s), ξ_2(s), ξ}_4(s), and ξ_6(s), with s denoting the comoving separation) to measure H(z), D_A(z)$, and beta(z), and validate it using LasDamas mock galaxy catalogs. Our definition of effective multipoles explicitly incorporates the discreteness of measurements, and treats the measured correlation function and its theoretical model on the same footing. We find that for the mock data, ξ_0+ξ_2+ξ_4 captures nearly all the information, and gives significantly stronger constraints on H(z), D_A(z), and beta(z), compared to using only ξ_0+ξ_2. We apply our method to the sample of luminous red galaxies (LRGs) from the Sloan Digital Sky Survey (SDSS) Data Release 7 (DR7) without assuming a dark energy model or a flat Universe. We find that ξ}_4(s) deviates on scales of s<60Mpc/h from the measurement from mock data (in contrast to ξ_0(s), ξ_2(s), and ξ_6(s)), thus we only use ξ_0+ξ_2 for our fiducial constraints. We obtain {H(0.35), D_A(0.35), Omega_mh^2, beta(z)} = {79.6_{-8.7}^{+8.3} km/s/Mpc, 1057_{-87}^{+88}Mpc, 0.103\pm0.015, 0.44\pm0.15} using ξ_0+ξ_2. We find that H(0.35)r_s(z_d)/c and D_A(0.35)/r_s(z_d) (where r_s(z_d) is the sound horizon at the drag epoch) are more tightly constrained: {H(0.35)r_s(z_d)/c, D_A(0.35)/r_s(z_d)} = {0.0437_{-0.0043}^{+0.0041}, 6.48_{-0.43}^{+0.44}\} using ξ_0+ξ_2.

Study of the minute virus of mice cell entry
Creators: name: Garcin, Pierre
Publisher: name: University of British Columbia
Year: 2014

description: The minute virus of mice prototype (MVMp) is a non-enveloped single stranded DNA virus of the family Parvoviridae. MVMp is one of the smallest viruses and shows intriguing abilities to preferentially infect and kill cancer cells (oncotropism/oncolytism), suggesting a potential for MVMp as an anti-cancer agent. Unfortunately, there is a lack of knowledge of the early events of MVMp infection cycle, such as binding to the cell surface and subsequent endocytosis. In an attempt to identify cellular partners of MVMp infection, our lab performed a mass spectrometry analysis of MVMp potential binding partners. Following this analysis, the galactose-binding lectin (galectin) 3 (Gal-3) was identified as binding partner for MVMp. Given the involvement of this extra-cellular matrix protein in the clustering and endocytosis of cell surface receptors, and its up-regulation in various aggressive tumor cells, I hypothesized that Gal-3 could play a role in MVMp cell entry, and potentially in its oncotropism. Using siRNA knockdown of Gal-3 in different cells followed by immunofluorescence microscopy analysis, I found that Gal-3 is necessary for an efficient MVMp cell entry and infection in different cells. Moreover, I discovered that the Golgi enzyme β1,6-acetylglucosaminyltransferase 5 (Mgat5), whose role is the addition of complex N-glycosylation to various cell surface receptors for Gal-3 binding, is required for MVMp infection. I also found that cancer cells with higher Gal-3 expression are more susceptible to MVMp infection than cells with lower Gal-3 levels. Next I used a combination of flow cytometry, immuno-fluorescence and transmission electron microscopy to characterize the early events of MVMp infection in various tissue-culture cell lines. My results show that many crucial parameters of the mesenchymal cell migration process regulate MVMp cellular entry and infection. I found that MVMp relies on cell protrusions to cluster at the leading edge of migrating cells rapidly after binding to the plasma membrane, from where it is subsequently endocytosed. Moreover, transmission electron microscopy analysis revealed that MVMp uses various endocytic pathways, which was confirmed using drug inhibitors of endocytosis. Finally, I found that epithelial-mesenchymal transition, an inducer of cancer cell migration, triggers MVMp infection in highly dividing non-permissive cancer cells.

description: Die Resistenz gegen Antibiotika ist ein wachsendes Problem, das unsere Fähigkeit bedroht, Infektionen zu behandeln und auf die Notwendigkeit drängt, neuartige Alternativen für „konventionelle“ Antibiotika zu entwickeln, die weniger anfällig für die Entwicklung bakterieller Resistenzen sind. Antimikrobielle Peptide (AMPs) gehören zu den vielversprechendsten Anwärtern. Dieses liegt an ihrer Fähigkeit, biologische Membranen durch unspezifische Wechselwirkungen mit den Komponenten der Lipidmembranen zu stören. Trotz der großen Menge an experimentellen Daten sind viele Aspekte der AMPs noch nicht gut verstanden. Dieses schließt ihren molekularen Wirkungsmechanismus, die Rolle der Membraneigenschaften, den Einfluss der Struktur und der Eigenschaften der antibiotischen Peptide, das Ausmaß und die Signifikanz der Porenbildung und Membranmizellisierung ein. In der vorliegenden Arbeit wurden zwei Gruppen von synthetischen hergestellten AMPs verwendet: 1) zu unterschiedlicher Helizität neigende, amphipathische KLA-Peptide und 2) ein lineares sowie ein zyklisches arginin- und tryptophanreiches antimikrobielles Hexapeptid mit identischen Aminosäuresequenzen (Ac-RW bzw. C-RW). Um die Wechselwirkung dieser Peptide mit verschiedenen Modell-Lipidmembranen unterschiedlicher Zusammensetzung zu untersuchen, wurden verschiedene biophysikalische Methoden wie z. B. DSC, ITC, DLS, IRRAS, FT-IR, und Epifluoreszenzmikroskopie eingesetzt. Phosphatidylglycerol (PG), Phosphatidylethanolamin (PE) und PG/PE-Mischungen wurden als Modell der bakteriellen Zytoplasmamembran benutzt, während Phosphatidylcholin (PC) die äußere Membranschicht der Säugetier-zellen repräsentieren sollte. Unser Ziel war es, die Wechselwirkung zwischen der Peptidkonformation, der Membranzusammensetzung und den -eigenschaften, sowie den experimentellen Bedingungen zu untersuchen und deren Einfluss auf die Wirksamkeit der Peptide auf Modellmembranen zu indentifizieren. Zusätzlich konnte die unterschiedliche Bioaktivität der Peptide mit Hilfe der Experimente an Modellmembranen erklärt werden. Diese Studie erweitert unser Wissen und Verständnis der komplexen Wechselwirkungen zwischen AMPs und Modellmembranen. Die Koppelung der verschiedenen biophysikalischen Methoden erlaubt es, die untersuchten Systeme von verschiedenen Seiten zu erforschen sowie mögliche methodenabhängige Abweichungen der Resultate zu überprüfen. Unsere Ergebnisse zeigen die entscheidende Bedeutung der Peptidkonformation und der lokalen Peptidkonzentration für die Bestimmung der Wirkungsweise der AMPs. Unsere Studie weist außerdem daraufhin, dass ein Phänomen, das für bestimmte Lipidmembranen, Vorbereitungsverfahren und unter bestimmten experimentellen Bedingungen beobachtet wird, nicht unter allen Umständen verallgemeint werden darf.

description: We obtain the Mellin transforms of the generalized fractional integrals and derivatives that generalize the Riemann-Liouville and the Hadamard fractional integrals and derivatives. We also obtain interesting results, which combine generalized $δ_{r,m}$ operators with generalized Stirling numbers and Lah numbers. For example, we show that $δ_{1,1}$ corresponds to the Stirling numbers of the $2^{nd}$ kind and $δ_{2,1}$ corresponds to the unsigned Lah numbers. Further, we show that the two operators $δ_{r,m}$ and $δ_{m,r}$, $r,m\in\mathbb{N}$, generate the same sequence given by the recurrence relation \[ S(n,k)=\sum_{i=0}^r \big(m+(m-r)(n-2)+k-i-1\big)_{r-i}\binom{r}{i} S(n-1,k-i), \;\; 0< k\leq n, \] with $S(0,0)=1$ and $S(n,0)=S(n,k)=0$ for $n>0$ and $1+min\{r,m\}(n-1) < k $ or $k\leq 0$. Finally, we define a new class of sequences for $r \in \{\frac{1}{3}, \frac{1}{4}, \frac{1}{5}, \frac{1}{6}, ...\}$ and in turn show that $δ_{\frac{1}{2},1}$ corresponds to the generalized Laguerre polynomials.

description: We consider the problem of recovering items matching a partially specified pattern in multidimensional trees (quadtrees and $k$-d trees). We assume the traditional model where the data consist of independent and uniform points in the unit square. For this model, in a structure on $n$ points, it is known that the number of nodes $C_n(ξ)$ to visit in order to report the items matching a random query $ξ$, independent and uniformly distributed on $[0,1]$, satisfies $\mathbf {E}[{C_n(ξ)}]\simκn^β$, where $κ$ and $β$ are explicit constants. We develop an approach based on the analysis of the cost $C_n(s)$ of any fixed query $s\in[0,1]$, and give precise estimates for the variance and limit distribution of the cost $C_n(x)$. Our results permit us to describe a limit process for the costs $C_n(x)$ as $x$ varies in $[0,1]$; one of the consequences is that $\mathbf {E}[{\max_{x\in[0,1]}C_n(x)}]\sim γn^β$; this settles a question of Devroye [Pers. Comm., 2000].

Art education and new media : understanding the roles of artists and educators in the age of immediacy
Creators: name: Ryoo, Anna
Publisher: name: University of British Columbia
Year: 2014

description: This thesis is an act of inquiry into the entangled relationship between new media and art and how art education should re-position itself towards the cultural, political, and social shifts brought on by new media. By positioning new media as an entity yet-to-be-understood, I drew upon Marshall McLuhan’s writings as well as diverse and intersecting views of new media from debates and discussions occurring in multiple fields of studies. These are offered in the hopes of providing various spaces in which we may think about what art and art education is and can be as well as to expose the complexity behind thinking about the relationships among the following terms: contemporary, new, media, art, and education. Questions raised in this study do not stem from a mode of resistance nor celebration, but rather from the positions of being an educator, an artist, and a researcher who seeks to critically and reflexively examine and make sense of her role and that of others in this creative ecology. Toward the end of this journey, it became more evident that new media indeed needs to be embraced and its potentials recognized if art education is to revitalize its curricula and pedagogies. However, to do so, I argue that we must approach new media through art first and foremost, and then new media, focusing on cultivating an environment within which new media is approached and understood from the perspective of artists.

description: We give the diffeomorphism classification of complete intersections with S^1-symmetry in dimension less than or equal to 6. In particular, we show that a 6-dimensional complete intersection admits a smooth non-trivial S^1-action if and only if it is diffeomorphic to the complex projective space or the quadric. We also prove that in any odd complex dimension only finitely many complete intersections can carry a smooth effective action by a torus of rank $>1$.

From "Extinct Monsters" to Deep Time : an ethnography of fossil exhibits production at the Smithsonian's National Museum of Natural History
Creators: name: Marsh, Diana Elizabeth
Publisher: name: University of British Columbia
Year: 2014

description: This dissertation traces the relationship between changing institutional cultures and the communication of knowledge to the public through exhibits, explored through an ethnographic and historical case study of a single set of halls at one museum—the fossil halls at the Smithsonian National Museum of Natural History (NMNH). Having documented the first six months of planning for the NMNH’s new exhibit project, Deep Time, I show that many of the values and practices in current exhibits production have their roots in major cultural, professional and institutional shifts of the late-1950s. These changes, enacted and dramatized in exhibits production, came to transform the communication of science through exhibits. Indeed, I argue, the production of exhibits offers unique insight into the workings of an institution by describing a microcosm of the museum where what I have called disciplinary “complementarities” and “frictions” are debated and performed by small, increasingly interdisciplinary groups of people. Exhibit development thus emerges as a political and subjective creative act, rooted in particular institutional contexts and histories, that takes place at the intersection of paradoxical institutional missions and divergent disciplinary cultures. In the chapters of this thesis, I will contextualize and trace collaborative complementarities and frictions that emerge at three levels of exhibits production: exhibit content, group dynamics, and institutional mission. I will argue that these three layers of complementarities/frictions (from the micro-level of content specific to the planning of the fossil hall complex, to the experts that develop exhibits, to the broadest institutional mission of the museum) as revealed in the exhibits production process, have at their root foundational dual roles of the Smithsonian that are both paradoxical and necessary in creative exhibits production.

description: Kardiale Effekte von Serotonin (5-HT) werden beim Menschen über den 5-HT4-Rezeptor vermittelt. Es wurden transgene Mäuse generiert, welche den humanen 5-HT4a-Rezeptor herzspezifisch überexprimieren. Die kardialen Einflüsse von 5-HT auf die Wildtypen (WT) und transgenen Tiere (TG) wurden in vivo mittels Linksherzkathetertechnik untersucht. Signifikante Unterschiede zwischen WT und TG nach Stimulation mit 5-HT zeigten sich im Anstieg von Herzfrequenz und Druckabfallgeschwindigkeit der TG. In vitro wurden Frequenz- und Kontraktionskraftmessungen an isolierten rechten und linken Vorhöfen von TG und WT durchgeführt. Es zeigte sich unter 5-HT ein Anstieg der Herzfrequenz der rechten Vorhöfe sowie der Kontraktionskraft und der Phopsholamban-Phosphorylierung der linken Vorhöfe der TG. Die positive Inotropie und Chronotropie der TG-Vorhöfe konnten in Anwesenheit spezifischer 5-HT4-Rezeptor-Antagonisten abgeschwächt werden. Die linken Vorhöfe der TG zeigten häufiger spontane arrhythmische Kontraktionen als die der WT. Die Ergebnisse weisen auf funktionelle 5-HT4a-Rezeptoren in den Herzen der TG hin.
description: In human heart serotonin (5-HT) exerts pleiotropic effects, which are thought to be mediated via 5-HT4 receptors. Here, transgenic mice that overexpress the human 5-HT4a receptor were generated. Contractile studies were performed in isolated electrically driven left atrial preparations and spontaneously beating right atrial preparations of TG and wild type (WT). 5-HT increased force of contraction and phospholamban phosphorylation only in atrial preparations from TG but not from WT. The contractile effects of 5-HT in left atrial preparations could be blocked by 5-HT4 receptor-specific anatagonists. Only in right atrial preparations from TG but not WT, 5-HT exerted a positive chronotropic effect that could be attenuated by 5-HT4 receptor-specific antagonists. Moreover in left atrial preparations of TG a higher incidence of arrhythmias occurred compared to WT. Finally, intravenous infusion of 5-HT increased in vivo left ventricular pressure and its first derivative in TG but not in WT. The data suggest functional expression of human 5-HT4 receptors in the heart of TG mice.

description: This study deals with the optimisation of hybrid composite drive shafts operating at subcritical or supercritical speeds, using a genetic algorithm. A formulation for the flexural vibrations of a composite drive shaft mounted on viscoelastic supports including shear effects is developed. In particular, an analytic stability criterion is developed to ensure the integrity of the system in the supercritical regime. Then it is shown that the torsional strength can be computed with the maximum stress criterion. A shell method is developed for computing drive shaft torsional buckling. The optimisation of a helicopter tail rotor driveline is then performed. In particular, original hybrid shafts consisting of high-modulus and high-strength carbon fibre reinforced epoxy plies were studied. The solutions obtained using the method presented here made it possible to greatly decrease the number of shafts and the weight of the driveline under subcritical conditions, and even more under supercritical conditions. This study yielded some general rules for designing an optimum composite shaft without any need for optimisation algorithms.

description: Infrared divergences in scattering amplitudes arise when a loop momentum $\ell$ becomes collinear with a massless external momentum $p$. In gauge theories, it is known that the L-loop logarithm of a planar amplitude has much softer infrared singularities than the L-loop amplitude itself. We argue that planar amplitudes in N=4 super-Yang-Mills theory enjoy softer than expected behavior as $\ell \parallel p$ already at the level of the integrand. Moreover, we conjecture that the four-point integrand can be uniquely determined, to any loop-order, by imposing the correct soft-behavior of the logarithm together with dual conformal invariance and dihedral symmetry. We use these simple criteria to determine explicit formulae for the four-point integrand through seven-loops, finding perfect agreement with previously known results through five-loops. As an input to this calculation we enumerate all four-point dual conformally invariant (DCI) integrands through seven-loops, an analysis which is aided by several graph-theoretic theorems we prove about general DCI integrands at arbitrary loop-order. The six- and seven-loop amplitudes receive non-zero contributions from 229 and 1873 individual DCI diagrams respectively.
