description: We study the Hopf algebra structure and the highest weight representation of a multiparameter version of $U_{q}gl(2)$. The commutation relations as well as other Hopf algebra maps are explicitly given. We show that the multiparameter universal ${\cal R}$ matrix can be constructed directly as a quantum double intertwiner, without using Reshetikhin's transformation. An interesting feature automatically appears in the representation theory: it can be divided into two types, one for generic $q$, the other for $q$ being a root of unity. When applying the representation theory to the multiparameter universal ${\cal R}$ matrix, the so called standard and nonstandard colored solutions $R(μ,ν; μ', ν')$ of the Yang-Baxter equation is obtained.

description: The in medium dynamics of heavy particles are governed by transport coefficients. The heavy quark momentum diffusion coefficient, $κ$, is an object of special interest in the literature, but one which has proven notoriously difficult to estimate, despite the fact that it has been computed by weak-coupling methods at next-to-leading order accuracy, and by lattice simulations of the pure SU(3) gauge theory. Another coefficient, $γ$, has been recently identified. It can be understood as the dispersive counterpart of $κ$. Little is known about $γ$. Both $κ$ and $γ$ are, however, of foremost importance in heavy quarkonium physics as they entirely determine the in and out of equilibrium dynamics of quarkonium in a medium, if the evolution of the density matrix is Markovian, and the motion, quantum Brownian; the medium could be a strongly or weakly coupled plasma. In this paper, using the relation between $κ$, $γ$ and the quarkonium in medium width and mass shift respectively, we evaluate the two coefficients from existing 2+1 flavor lattice QCD data. The resulting range for $κ$ is consistent with earlier determinations, the one for $γ$ is the first non-perturbative determination of this quantity.

description: A field-scale tree trial was established in 2013 and 2014 on rock disposal site slopes at Mount Polley Mine to evaluate herbaceous groundcovers’ ability to promote coniferous tree growth on parcels amended with biosolids. Parcels were amended with 20 cm of overburden and biosolids were applied at a rate of 110 dry tonnes per hectare (control parcels received no biosolids). The parcels were then seeded with either: native grasses and forbs (at 5 kg/ha or 10 kg/ha), native forbs, fireweed, or unseeded. The control parcels were also unseeded. Lodgepole pine, Douglas-fir, and deciduous tree and shrub seedlings were planted across all parcels. After two and three growing seasons, herbaceous vegetative cover was highest on parcels seeded with native grasses and lowest on the forbs, fireweed, and unseeded parcels. Higher cover was associated with greater competition with conifer seedlings, increased vegetation/snow press, increased herbivory and reduced seedling survival. Growth of the conifers however, was higher on the parcels amended with biosolids compared to control parcels. These results suggest that the understory on biosolids amended soils should be seeded at low seeding rates with native forbs in order to have the highest conifer survival while still providing erosion and invasive plant control.

description: Ever-growing demand for speed and bandwidth coupled with increasing energy consumption in current networks are driving the need for intelligent, next-generation networking architectures that can overcome fundamental spectral and energy limitations. Metro-only internet traffic in particular is experiencing unprecedented growth rates and increasing twice as fast as long-haul traffic. The current quasi-static peak capacity pro- visioned network is ill-equipped to support this rise of unpredictable, high bandwidth but short-duration traffic flows. A promising solution to address the emerging networking challenges is agile optical networking. Agile optical networking leverages novel photonic devices and multi-layer switching capabilities along with network awareness and intelligence to allocate re- sources in accordance to changing traffic demands and network conditions. However, network agility requires changing the wavelength configuration in the optical layer in real-time to match the traffic demands. Rapidly changing the wavelength loading conditions in optical amplifiers result in debilitating power fluctuations that propagate through the network and can lead to network instability, a problem that is avoided in current networks by using long reconfiguration times encompassing many small adjustments. An agile optical network, once successfully implemented, will be characterized by unpredictable transmission impairments. Power levels along any path in an agile network is constantly fluctuating due to the continuously changing wavelength configuration; consequently, power dependent transmission impairments are also constantly fluctuating. Real-time knowledge of the state of the physical layer is thus critical for managing signal quality and reliability in an agile optical network, requiring the development of cost-effective, energy-efficient monitoring solutions that can support advanced modulation formats. This dissertation focuses on developing solutions for the two key requirements for a stable agile optical network. Techniques that allow wavelength reconguration on the order of seconds while maintaining stable network operation and minimal data loss are presented. Functionality of an existing advanced optical performance monitor is extended to include autonomous monitoring of both single and multiple channel systems, so that it can be used in agile optical network for real-time introspection of the physical layer.

description: We report first observation of photon tunneling gated by light at a different wavelength in an artificially created array of nanometer scale cylindrical channels in a thick gold film. Polarization properties of gated light provide strong proof of the enhanced nonlinear optical mixing in nanometric channels involved in the process. This suggests the possibility of building a new class of "gated" photon tunneling devices for massive parallel all-optical signal and image processing.

description: Silk-elastinlike protein polymers (SELPs) self-assemble into nanostructures when designed with appropriate silk-to-elastin ratios. Here, we investigate the effect of insertion of a matrix metalloproteinase-responsive peptide sequence, GPQGIFGQ, into various locations within the SELP backbone on supramolecular self-assembly. Insertion of the hydrophilic, enzyme-degradable sequence into the elastin repeats allows the formation of dilution-stable nanostructures, while insertion into the hydrophobic silk motifs inhibited self-assembly. The SELP assemblies retained their lower critical solution temperature (LCST) thermal response, allowing up to eightfold volumetric changes due to temperature-induced size change. A model hydrophobic drug was incorporated into SELP nanoassemblies utilising a combination of precipitation, incubation and tangential flow filtration. While the nanoconstructs degraded in response to MMP activity, drug release kinetics was independent of MMP concentration. Drug release modelling suggests that release is driven by rates of water penetration into the SELP nanostructures and drug dissolution. In vitro testing revealed that SELP nanoassemblies reduced the immunotoxic and haemolytic side effects of doxorubicin in human blood while maintaining its cytotoxic activity.

description: The recently realized photonic crystal Fano laser constitutes the first demonstration of passive pulse generation in nanolasers [Nat. Photonics $\boldsymbol{11}$, 81-84 (2017)]. We show that the laser operation is confined to only two degrees-of-freedom after the initial transition stage. We show that the original 5D dynamic model can be reduced to a 1D model in a narrow region of the parameter space and it evolves into a 2D model after the exceptional point, where the eigenvalues transition from being purely to a complex conjugate pair. The 2D reduced model allows us to establish an effective band structure for the eigenvalue problem of the stability matrix to explain the laser dynamics. The reduced model is used to associate a previously unknown origin of instability with a new unstable periodic orbit separating the stable steady-state from the stable periodic orbit.

Luperodes Motschulsky, 1858: 102 (type species Luperodes alboplagiatus Motschulsky, 1858, by subsequent designation of Weise 1924).
Remarks
Wilcox (1973) listed 53 extant New World species for this genus, occurring from Mexico through the northern half of South America. He also listed one fossil species from Colorado. However, future taxonomic revision of the Monoleptites may eventually show that true Luperodes does not occur in the New World. Wagner & Bieneck (2012) studied the type species of Luperodes and made some notes on the genus. They seem to agree with the conclusion that the New World species are probably misplaced. The genus was originally named from Sri Lanka. The New World species currently included in the genus are hardly distinguishable from those currently in Lilophaea, Metrioidea, and Monolepta. See Fig. 141 for a habitus illustration of one of the New World species currently included in Luperodes.

description: An Hand eines bisher unbekannten Briefes von Guericke ergibt sich, daß die jetzt im Deutschen Museum in München befindlichen Magdeburger Halbkugeln im September 1663 nach Berlin gelangten. Wie bereits bekannt war, wurden dort Versuche mit der Luftpumpe im Dezember 1663 vorgeführt, so daß also auch die Berlin- Münchener Luftpumpe sich damals schon in Berlin befunden haben muß. - In Übereinstimmung mit den von W. Ahrens getroffenen Feststellungen wird gezeigt, daß die in Braunschweig befindliche Luftpumpe und die beiden Paare von Halbkugeln höchstwahrscheinlich aus dem Besitz der Familie Guericke stammen. - Für die Zeit des Baues und der Benutzung der drei Typen Guerickescher Luftpumpen werden für Typ I, der in Regensburg benutzt wurde, die Jahre von etwa 1650 bis nach 1654, für Typ II etwa 1656 bis 1662 und für Typ III, den einzigen uns erhaltenen, die Jahre nach 1662/63 wahrscheinlich gemacht. - Eine bisher unbekannte Anleitung zu Versuchen mit der Luftpumpe, vermutlich nach 1664 verfaßt, und eine ebenfalls noch unbekannte Anweisung zu Wettervoraussagen mittels des Barometers, beide von Guerickes Hand, werden erstmals veröffentlicht und kurz kommentiert.
description: From the evidence of a hitherto unknown letter of Guericke follows that the "Magdeburg hemispheres", which are kept now by the Deutsches Museum in Munich, found their way to Berlin in September 1663. Since it is known that in December 1663 at the very same place there were performed some experiments with the air-pump, it is evident that the so-called Berlin (resp. Munich) pump happened to be at Berlin even then. - It is further shown in concert with the results reached by the investigations of W. Ahrens, that both, the Brunswick pump and the two pairs of hemispheres, now kept even there, may be traced back to the personal property of the Guericke family. - Concerning the date, to which the construction and the use of the three different types of Guericke pumps ought to be assigned, it seems likely to place type I, used at Regensburg, between 1650 and 1654 and later, type II between about 1656 and 1662, type III, the only one still existant, between 1662 and 1663. - A hitherto unknown manual concerning some experiments with the air-pump, written probably after 1664, and an also hitherto unknown guide dealing with weather forecasts by the aid of the barometer ("Wettermännlein"), written by Guericke himself, are first published with a brief comment.

Direct evaluation of dynamical large-deviation rate functions using a variational ansatz

description: We describe a simple form of importance sampling designed to bound and compute large-deviation rate functions for time-extensive dynamical observables in continuous-time Markov chains. We start with a model, defined by a set of rates, and a time-extensive dynamical observable. We construct a reference model, a variational ansatz for the behavior of the original model conditioned on atypical values of the observable. Direct simulation of the reference model provides an upper bound on the large-deviation rate function associated with the original model, an estimate of the tightness of the bound, and, if the ansatz is chosen well, the exact rate function. The exact rare behavior of the original model does not need to be known in advance. We use this method to calculate rate functions for currents and counting observables in a set of network- and lattice models taken from the literature. Straightforward ansatze yield bounds that are tighter than bounds obtained from Level 2.5 of large deviations via approximations that involve uniform scalings of rates. We show how to correct these bounds in order to recover the rate functions exactly. Our approach is complementary to more specialized methods, and offers a physically transparent framework for approximating and calculating the likelihood of dynamical large deviations.

description: We analyze the capacity of future $Z$-factories to search for heavy neutrinos with their mass from 10 to 85 GeV. The heavy neutrinos $N$ are considered to be produced via the process $e^+e^-\to Z\to νN$ and to decay into an electron or muon and two jets. By means of Monte Carlo simulation of such signal events and the Standard Model background events, we obtain the upper bounds on the cross sections $σ(e^+e^-\to νN\to ν\ell jj)$ given by the $Z$-factories with integrated luminosities of 0.1, 1 and 10 ab$^{-1}$ if no signal events are observed. Under the assumption of a minimal extension of the Standard Model in the neutrino sector, we also present the corresponding constraints on the mixing parameters of the heavy neutrinos with the Standard Model leptons, and find they are improved by at least one order compared to current experimental constraints.

description: When we talk about ‘audience’ in Science Communication what do we mean? ‘Audience’ is central to Science Communication. However, despite - and perhaps because of - ‘audience’s’ centrality to the field, concepts of ‘audience’ are often implicit rather than explicitly communicated. This Honours Thesis unravels these often implicit conceptions of ‘audience’ through investigating 1360 Science Communication research articles and surveying 45 Science Communication tertiary level educators. I found that overwhelmingly our conceptions of ‘audience’ are plural, rich, and cover a wide array of conceptual categories. This indicates that there are many ways in Science Communication to frame our thoughts of audience. Building beyond conceptions of a ‘general’ audience, I found there are clear yet entwining conceptual categories of ‘audience’ across both Science Communication researchers and educators. This thesis further divides these conceptual categories in groups. One group includes categories that singularly describe ‘audience’ in Science Communication such as demographic, embodied, interaction based, knowledge, and values. The other group contains categories that span multiple conceptual ideas of audiences such as diverse, dynamic, future, and multiple. Together these two groups of conceptual categories highlight the complexities, abundance, and varieties of understandings of ‘audience’ used by Science Communicators. This study unfurls ‘audience’ so that Science Communicators may use and hold a more rich, robust, and explicit understanding of ‘audience’.

A particular approach to the surroundings, which is the basis of all designs, is the explanation of individual structure. This raises the hope that a noticeable individuality will result also from the present style of building which is practically similar throughout the whole world.

description: A key feature of ground states of gapped local 1D Hamiltonians is their relatively low entanglement --- they are well approximated by matrix product states (MPS) with bond dimension scaling polynomially in the length $N$ of the chain, while general states require a bond dimension scaling exponentially. We show that the bond dimension of these MPS approximations can be improved to a constant, independent of the chain length, if we relax our notion of approximation to be more local: for all length-$k$ segments of the chain, the reduced density matrices of our approximations are $ε$-close to those of the exact state. If the state is a ground state of a gapped local Hamiltonian, the bond dimension of the approximation scales like $(k/ε)^{1+o(1)}$, and at the expense of worse but still $\text{poly}(k,1/ε)$ scaling of the bond dimension, we give an alternate construction with the additional features that it can be generated by a constant-depth quantum circuit with nearest-neighbor gates, and that it applies generally for any state with exponentially decaying correlations. For a completely general state, we give an approximation with bond dimension $\exp(O(k/ε))$, which is exponentially worse, but still independent of $N$. Then, we consider the prospect of designing an algorithm to find a local approximation for ground states of gapped local 1D Hamiltonians. When the Hamiltonian is translationally invariant, we show that the ability to find $O(1)$-accurate local approximations to the ground state in $T(N)$ time implies the ability to estimate the ground state energy to $O(1)$ precision in $O(T(N)\log(N))$ time.

description: Das Verhalten von wasserstoffhaltigem Stahl wird kurz beschrieben. Dann wird über Zugversuche berichtet, welche in einer Wasserstoffatmosphäre höheren Druckes (bis 150 atü) durchgeführt wurden. Ist Wasserstoff während der plastischen Verformung von Stahl zugegen, so tritt eine Schädigung der Oberfläche durch Rißbildung und ein starker Abfall der Zähigkeit ein. Steigender Wasserstoffdruck und sinkende Verformungsgeschwindigkeit erhöhen die versprödende Wirkung des Gases. In einer Arbeitshypothese wird die Wirkungsweise des Wasserstoffs mit der Dissoziation von Wasserstoffmolekülen und Adsorption von Wasserstoffatomen an den durch die Verformung freigelegten Oberflächen in Zusammenhang gebracht.
description: The behaviour of steel containing hydrogen is briefly described. Then a report is given about tensile tests conducted in a hydrogen atmosphere of elevated pressures (up to 2133 lb./sq.in.). If hydrogen is present during plastic deformation of the steel, a deterioration of the surface in form of cracks and a considerable loss of ductility will occur. Increasing hydrogen pressure and decreasing strain-rate intensify the embrittling effect of the gas. The authors try to explain the action of hydrogen by dissociation of hydrogen molecules and adsorption of atoms on surfaces set free during deformation.

Drug release modeling suggests that release is driven by rates of water penetration into the SELP nanostructures and drug dissolution. In vitro testing revealed that SELP nanoassemblies reduced the immunotoxic and hemolytic side effects of doxorubicin in human blood while maintaining its cytotoxic activity.

A new paradigm for modulated phases in multi-stage structural transformations

description: For multi-stage, displacive structural transitions we present a general framework that accounts for various intermediate modulated phases, elastic constant, phonon and related thermodynamic anomalies. Based on the presence or absence of modulated phases we classify these transformations in four categories and apply this approach to four different representative materials: Ni-Mn-Ga, NiTi(Fe),Ni-Al, Cu-Zn-Al and alpha-U. We suggest that the anomalous increase in elastic constant(s) and phonon frequency observed when approaching the martensitic transition from above is a signature of the conmensurate modulated phase.

Reality and Representation in Giovanni Verga

description: The works published by Giovanni Verga (1840-1922) between 1878 and 1889 exposed Italian culture to the most innovative European literary trend, French Naturalism, and marked a turning point in the landscape of Italian literature. While Verga’s stylistic choices are meant to create, in his own words, ‘the complete illusion of reality’ (having the author disappear from the text in order to make way for a supposedly unmediated representation), I argue that Verga’s Verist fiction ends up emphasizing precisely the ways in which people represent reality according to their own relative point of view. Since the narrative is given from the unreliable perspective of the characters, all the distortions inherent in every storytelling act become apparent. Their viewpoint is purposefully shown as being partial and informed by individual interests, feelings, and desires. These complex dynamics of representation, or misrepresentation, in Verga’s Verist production are at the heart of my enquiry. This critical focus allows me to reevaluate the traditional representation of Verism and Naturalism as backward-looking phenomena, firmly tied to a notion of art as a mirror up to nature. The present study is situated within a growing body of work (inaugurated by Luperini, Pellini, and Merola) that intends to re-frame Verga as having demonstrably paved the way for twentieth-century Modernism. The first chapter interrogates the way in which space is transfigured by characters in I Malavoglia (1881). By looking at how narratives of country vs city, past vs present are formed and shaped by the characters’ relative points of view, I argue that the novel should be read not simply as the account of the modernization of a rural village in post-unification Italy, but mainly as a study into how such oppositional narratives are formed and what aims they serve. The second chapter focuses on a specific character-type, the malevolent observer. I argue that this figure can be seen as a representation of the readers in the texts and that it is instrumental in exemplifying Verga’s skepticism toward the heuristic potential of literature. The third chapter examines the gap between reality and representation as articulated in Mastro-don Gesualdo (1889) by situating Verga in a completely new intellectual framework, that of elite theory as formulated by political theorist Gaetano Mosca (1858-1941) and sociologist Vilfredo Pareto (1848-1923). This move allows me to re-read what has become a commonplace of Verga criticism – the theatrical conception of politics in Mastro-don Gesualdo as a bitter commentary on trasformismo – as a much wider point on social history, human nature, and on the inherently slippery essence of language, on its built-in capacity to deceive and dissimulate.

description: Twinkle is an upcoming 0.45m space-based telescope equipped with a visible and two near-infrared spectrometers covering the spectral range 0.4 to 4.5μm with a resolving power R~250 (λ<2.42μm) and R~60 (λ>2.42μm). We explore Twinkle's capabilities for small bodies science and find that, given Twinkle's sensitivity, pointing stability, and spectral range, the mission can observe a large number of small bodies. The sensitivity of Twinkle is calculated and compared to the flux from an object of a given visible magnitude. The number, and brightness, of asteroids and comets that enter Twinkle's field of regard is studied over three time periods of up to a decade. We find that, over a decade, several thousand asteroids enter Twinkle's field of regard with a brightness and non-sidereal rate that will allow Twinkle to characterise them at the instrumentation's native resolution with SNR > 100. Hundreds of comets can also be observed. Therefore, Twinkle offers researchers the opportunity to contribute significantly to the field of Solar System small bodies research.

description: The perturbation theory for calculation of the effective conductivity of the plane consisting of pieces of different conductivities is constructed and the convenient diagram technique for this perturbation theory is elaborated. It is shown that for the chessboard perturbative calculations give results which are in agreement with the well-known formula $σ_{eff} = \sqrt{σ_1σ_2}$. The components of the tensor of effective conductivity for the anisotropic three-color chessboard are calculated. It is shown that the isotropic (symmetric) part of effective conductivity calculated up to the sixth order of perturbation theory satisfies the Bruggeman effective medium equation for symmetric three-color structures with equally partitioned components. We also consider isotropic three-color chessboard with nonequal weights of colors. In this case the perturbation theory already in fourth order contradicts the results following from the Bruggeman equation for nonequal weights.

description: We solve the direct scattering problem for the ultradiscrete Korteweg de Vries (udKdV) equation, over $\mathbb R$ for any potential with compact (finite) support, by explicitly constructing bound state and non-bound state eigenfunctions. We then show how to reconstruct the potential in the scattering problem at any time, using an ultradiscrete analogue of a Darboux transformation. This is achieved by obtaining data uniquely characterising the soliton content and the `background' from the initial potential by Darboux transformation.
