description: Meningoencephalitis patients are often severely impaired and benefit from early etiological diagnosis, though many cases remain without identified cause. Metagenomics as pathogen agnostic approach can result in additional etiological findings; however, the exact diagnostic yield when used as a secondary test remains unknown. This review aims to highlight recent advances with regard to wet and dry lab methodologies of metagenomic testing and technical milestones that have been achieved. A selection of procedures currently applied in accredited diagnostic laboratories is described in more detail to illustrate best practices. Furthermore, a meta-analysis was performed to assess the additional diagnostic yield utilizing metagenomic sequencing in meningoencephalitis patients. Finally, the remaining challenges for successful widespread implementation of metagenomic sequencing for the diagnosis of meningoencephalitis are addressed in a future perspective. The last decade has shown major advances in technical possibilities for using mNGS in diagnostic settings including cloud-based analysis. An additional advance may be the current established infrastructure of platforms for bioinformatic analysis of SARS-CoV-2, which may assist to pave the way for global use of clinical metagenomics.

Lernen von der Medienkunst: Handlungsstrategien der Netzwerk-Kultur

description: Der Begriff der Medienkunst wird mit fortschreitender Medialisierung der Welt immer problematischer. Die Digitalisierung hat alle künstlerischen Medien (ob technische oder nicht) als Medien sichtbar gemacht und deren Verhältnis untereinander grundlegend verändert. Rosalind Krauss bezeichnet dieses neue Verhältnis als "post-medium condition" (Krauss 2000). Wenn wir also von der Medienkunst etwas über Medien lernen wollen, was für eine Medienpädagogik nutzbar ist, müssen wir die Entgrenzung des Medialen berücksichtigen. Diese macht die Abgrenzung von Medienkunst von anderen Künsten sehr schwierig, da eine solche künstlerische Praxis weder an formalen, inhaltlichen oder materiellen Eigenschaften festgemacht werden kann. Ich schlage in diesem Text vor, die Medienkunst in ihren methodischen Strategien zu betrachten. Ihre Referenzen in der Kunstgeschichte sind dabei die Konzeptkunst und die Institutionskritik, als kulturgeschichtlichen Hintergrund komme ich auf die Kybernetik zurück. Im vorliegenden Essay möchte ich versuchen, Anschlussmöglichkeiten einer kritischen Medienpädagogik an die aus der Kybernetik entstandene gegenwärtige Netzwerkkultur zu formulieren. Netzwerkkultur bezeichnet dabei nicht die spezifischen Technologien des Internets wie das Social Web, sondern die aus dem Geiste der Kybernetik entstandenen Formen vernetzter Handlungsmöglichkeiten, zu denen unter anderen auch das Social Web gehören.

description: We count the number of histories between the two degenerate minimum energy configurations of the Ising model on a chain, as a function of the length n and the number d of kinks that appear above the critical temperature. This is equivalent to count permutations of length n avoiding certain subsequences depending on d. We give explicit generating functions and compute the asymptotics. The setting considered has a role when describing dynamics induced by quantum Hamiltonians with deconfined quasi-particles.

description: Les médias ont toujours joué un rôle majeur en offrant une voix à l'opinion publique. Leur premier rôle est de transmettre de l’information fiable et correcte au récepteur afin de lui donner une vision sur la scène sociale, économique ou politique. ils sont sans doute un élément essentiel du processus d’élaboration des politiques publiques. Dans cette perspective, le domaine des médias est devenu plus autonome et diversifié. Les médias sont aussi le reflet des débats démocratiques qui agitent la société. Notre article visait à explorer l’état du lien qui unit actuellement les médias et l’opinion politique; il vise à mettre en lumière le rôle des médias au Maroc dans la formulation des opinions politiques des citoyens, à partir des médias comme facteur d’influence politique ainsi que des contraintes et des perspectives du rapport entre médias et politique. Nous en avons déduit que la transformation des médias et la multiplication des sources d’information sont un fait. Cela nous incite à faire attention au risque que la disparition des médias professionnels, avec l’éthique qui doit les caractériser, ouvre la porte à une guerre d’influences où le citoyen pourrait être exploité et manipulé par la politique. En effet, le rôle des médias comme freins et contrepoids, offrant une information rigoureuse et fiable capable de former l’esprit critique des individus, reste essentiel au bon fonctionnement de la démocratie.

description: The Apollo 15 & 16 missions were the first to explore the Lunar surface chemistry by investigating about 10% of the Lunar surface using a remote sensing X-ray fluorescence spectrometer experiment. The data obtained have been extensively used to study Lunar formation history and geological evolution. In this work, a re-evaluation of the Apollo 15 & 16 X-ray fluorescence experiment is conducted with the aim of obtaining up-to-date empirical values for aluminum (Al) and magnesium (Mg) concentrations relative to silicon (Si) of the upper Lunar surface. An updated instrument response, a newly reconstructed Lunar trajectory orbit, and improved intensity ratio calculations were used to obtain new intensity ratio maps. The resulting Lunar Al/Si and Mg/Al X-ray maps show a clear distinction in Lunar mare and highland regions. The mean Al/Si and Mg/Al intensity ratios for the mare regions obtained from the newly obtained maps are 0.54$\pm$0.07 and 0.54$\pm$0.17, respectively; for the highland regions, the values are 0.76$\pm$0.07 and 1.07$\pm$0.13, respectively. For the Mg/Si intensity ratio, no clear distinction between Lunar features is obtained and we derived a mean value of 0.47$\pm$0.13. Our determined intensity ratios are lower than previously published. These values can be used to infer concentration ratios when accounting for Solar activity, inter-orbit variability, and measurements from different instruments. We employed a correction to infer concentration ratios by comparing our intensity ratios directly to Lunar rock concentrations obtained from various Lunar missions.

description: We present a superquantization rule which indicates the possible robust stationary states of a generic driven-dissipative quantum system. Multistability in a driven cavity mode interacting with a qudit is revealed in this way within a simple intuitive picture. The accuracy of the superquantization approach is confirmed by numerical simulations of the underlying quantum model. In the case when the qudit is composed of several two-level emitters coupled homogeneously to the cavity, we demonstrate the robustness of the superquantized steady states to single-emitter decay.

description: Im Kontext von Schul(re)formen spielen medienbezogene Rhetoriken eine beachtliche Rolle. Das gilt für me­dienskeptische und -euphorische Argumentationen gleichermaßen. Einerseits wird an das Erfordernis von Schonräumen und Entwicklungsaufgaben für Kinder und Jugendliche, die Ausdifferenzierung von Literalität als Bildungsaufgabe oder von möglichster Gleichheit der Chancen auf den Erwerb von Qualifikationen erinnert. Medien werden dann meistens als Hilfsmittel des Lernens, der Bildung oder der Entwicklungsförderung aufge­fasst. Andererseits geht es auch um die Entwicklung geeigneter Infrastrukturen für das Lernen und Lehren mit mehr oder weniger neuen Medien, mediengestützte Schulentwicklungsprojekte oder die Implementierung von e-Learning-Strategien. Dabei fällt auf, dass sich die Innovationsbemühungen bei näherer Betrachtung häufig als strukturkonservative Verwaltungsmaßnahmen erweisen, die an den zeitgenössischen medienanthropologischen, -epistemologischen und -kulturellen Herausforderungen vorbeigehen. Der Beitrag zielt auf eine Problematisierung schulischer Bildungs- und Informationsmonopole sowie auf die Sondierung erweiterter Perspektiven der Reflexion und Handlungsorientierung im Lichte der Theorie medialer Formen. [1] [1] Eine überarbeitete Fassung des Beitrags erscheint 2014 unter dem Titel "Media Form School – A Plea for Expanded Action Orientations and Reflective Perspectives" im Themenheft Nr. 24 der Online-Zeitschrift "MedienPädagogik" (medienpaed.com).

title: Housing is the Root of Wealth Inequality: Building an Equitable Richmond
Creators: name: Crislip, Heather Mullins
Publisher: name: Richmond Racial Equity Essays
Year: 2021

description: This is essay number 4 from the book Richmond Racial Equity Essays, edited by Ebony Walden and Meghan Z. Gough. It appears on pages 18-20 of the book in the section "Building and Sustaining Affordable Housing." The author examines how the dramatic differences in homeownership between white and Black households are not largely a function of income, as many often assume. There are structural barriers, both historic and contemporary, that deliver this result. An equitable Richmond would give all households the opportunity for stability and growth. The first step in this would be to have housing available that people can afford, distributed across the region to allow for choice, and opportunities for sustainable homeownership. A thriving Richmond would also break down racial and economic segregated housing patterns to create an integrated community.

description: We give an overview exploring the role of kinetics in multicomponent mixtures. Compared to the most commonly studied binary (single species plus solvent) case, multicomponent fluids show a rich interplay between kinetics and thermodynamics due to the possibility of fractionation, interdiffusion of mixture components and collective motion. This leads to a competition between multiple timescales that change depending on the underlying kinetics. At high densities, crowding effects are relevant and non-equilibrium structures can become long-lived. We present the main approaches for the study of kinetic effects in multicomponents mixtures, including the role of crowding, and explore their consequences for equilibrium and non-equilibrium scenarios. We conclude by identifying the main challenges in the field.
The State and the arts: the theatre scene in Turkey
Creators: name: TOnga, Yesim
Publisher: name: IMT Alti Studi Lucca
Year: 2014
Subjects: NX Arts in general

description: The arts scene in Turkey has been the subject of discussions since April 2012, with the revealing of the governmental
reform agenda on the state support model for the arts that includes the closure of the State Theatres and, the State Opera and Ballet. However, there has been a
strong public resistance against the closure of these public arts institutions, along with criticisms on the lack of essential assessment studies, inclusive
decision-making process and transparency. Within this framework, the thesis aims to investigate the ways in which the current state support model for the
theatre scene in Turkey can be improved considering the contextual specificities, achievements of the current support framework, infrastructure of the theatre
scene and the public opinion. Towards this end, a policy-oriented exploratory research was designed with an interdisciplinary approach. In addition to archival
research, media coverage and contextual analysis, an institutional performance analysis framework was developed to assess the achievements of the State Theatres.
Furthermore, the fieldwork was conducted in two parts; (i) a private / independent theatres survey was carried out with 24 theatres in Istanbul to analyse the infrastructure
of the field, and (ii) a public opinion survey was conducted with a sample of 436 participants in Istanbul to examine the attitudes towards arts and culture,
as well as the relation between these attitudes and the socio-economic profile. In light of the interdisciplinary analysis, the research provides a comprehensive
overview of the theatre field based on evidence and provides recommendations for generating a sustainable policy agenda for the arts and culture scene in Turkey.

description: Implementing virtual fixtures in guiding tasks constrains the movement of the robot's end effector to specific curves within its workspace. However, incorporating guiding frameworks may encounter discontinuities when optimizing the reference target position to the nearest point relative to the current robot position. This article aims to give a geometric interpretation of such discontinuities, with specific reference to the commonly adopted Gauss-Newton algorithm. The effect of such discontinuities, defined as Euclidean Distance Singularities, is experimentally proved. We then propose a solution that is based on a Linear Quadratic Tracking problem with minimum jerk command, then compare and validate the performances of the proposed framework in two different human-robot interaction scenarios.

description: A new class of cylindrically symmetric inhomogeneous cosmological models for perfect fluid distribution with electromagnetic field is obtained in the context of Lyra's geometry. We have obtained two types of solutions by considering the uniform as well as time dependent displacement field. The source of the magnetic field is due to an electric current produced along the z-axis. Only $F_{12}$ is a non-vanishing component of electromagnetic field tensor. To get the deterministic solution, it has been assumed that the expansion $θ$ in the model is proportional to the shear $σ$. It has been found that the solutions are consistent with the recent observations of type Ia supernovae and the displacement vector $β(t)$ affects entropy. Physical and geometric aspects of the models are also discussed in presence and absence of magnetic field.

Our approach extends, to self-propelling systems, the work of Ben Amar and Cummings [Phys Fluids 13 (2001) 1160] on thin-film nematics. Based on our estimates the instabilities should be seen in bacterial suspensions and the lamellipodium, and are potentially relevant to the morphology of biofilms. We suggest several experimental tests of our theory.

description: We present a thorough investigation of the physical properties and superconductivity of the binary intermetallic V2Ga5. Electrical resistivity and specific heat measurements show that V2Ga5 enters its superconducting state below Tsc = 3.5 K, with a critical field of Hc2,perp c(Hc2,para c) = 6.5(4.1) kOe. With H perp c, the peak effect was observed in resistivity measurements, indicating the ultrahigh quality of the single crystal studied. The resistivity measurements under high pressure reveal that the Tsc is suppressed linearly with pressure and reaches absolute zero around 20 GPa. Specific heat and muon spin relaxation measurements both indicate that the two-gap s-wave model best describes the superconductivity of V2Ga5. The spectra obtained from angle-resolved photoemission spectroscopy measurements suggest that two superconducting gaps open at the Fermi surface around the Z and Γ points. These results are verified by first-principles band structure calculations. We therefore conclude that V2Ga5 is a phonon-mediated two-gap s-wave superconductor

description: A method is proposed for producing monoergetic, high-quality ion beams in vacuum, via direct acceleration by the electromagnetic field of two counterpropagating, variable-frequency lasers: ions are trapped and accelerated by a beat-wave structure with variable phase velocity, allowing for fine control over the energy and the charge of the beam via tuning of the frequency variation. The physical mechanism is described with a one-dimensional theory, providing the general conditions for trapping and scaling laws for the relevant features of the ion beam. Two-dimensional, electromagnetic particle-in-cell simulations, in which hydrogen gas is considered as an ion source, confirm the validity and the robustness of the method.

The International Joint Commission : determinants of success
Creators: name: Makepeace, Garth O.
Publisher: name: University of British Columbia
Year: 2010

description: This thesis examines the organizational structure and decision-making process of the International Joint Commission. It does so by focussing on the Commission's investigation and report on the Garrison Diversion Unit during 1975-1977. The basic question which is asked is: Why does the International Joint Commission (IJC) enjoy a high reputation for successful resolution of disputes involving the transboundary and boundary waters of Canada and the United States? Two related hypothesis are proposed: (1) that the IJC is linked by means of its somewhat unique organizational structure to key bureaucratic agencies and departments in Canada and the United States and (2) that within the IJC's decision-making process strong norms of consensus and common-goal decision-making promote solution of disputes, most of which are based on very technical issues. Interview evidence and published material are used to establish initial support for these hypotheses. The paper closes with a discussion of problems which may endanger a continuation of IJC "success" and with a tentative proposal of improvements to IJC operations which may help negate this possibility.

description: Web phishing poses a dynamic threat, requiring detection systems to quickly adapt to the latest tactics. Traditional approaches of accumulating data and periodically retraining models are outpaced. We propose a novel paradigm combining federated learning and continual learning, enabling distributed nodes to continually update models on streams of new phishing data, without accumulating data. These locally adapted models are then aggregated at a central server via federated learning. To enhance detection, we introduce a custom attention-based classifier model with residual connections, tailored for web phishing, leveraging attention mechanisms to capture intricate phishing patterns. We evaluate our hybrid learning paradigm across continual learning strategies (cumulative, replay, MIR, LwF) and model architectures through an empirical investigation. Our main contributions are: (1) a new hybrid federated-continual learning paradigm for robust web phishing detection, and (2) a novel attention + residual connections based model explicitly designed for this task, attaining 0.93 accuracy, 0.90 precision, 0.96 recall and 0.93 f1-score with the LwF strategy, outperforming traditional approaches in detecting emerging phishing threats while retaining past knowledge.

description: By measuring the electrical transport properties of superconducting NbN quarter-wave resonators in direct contact with a helium bath, we have demonstrated a high-speed and spatially sensitive sensor for the permittivity of helium. In our implementation a $\sim10^{-3}$ mm$^3$ sensing volume is measured with a bandwidth of 300 kHz in the temperature range 1.8 to 8.8 K. The minimum detectable change of the permittivity of helium is calculated to be $\sim6\times$$10^{-11}$ $ε_0$/Hz$^{1/2}$ with a sensitivity of order $10^{-13}$ $ε_0$/Hz$^{1/2}$ easily achievable. Potential applications include operation as a fast, localized helium thermometer and as a transducer in superfluid hydrodynamic experiments.

description: A full understanding of high-mass star formation requires the study of one of the most elusive components of the energy balance in the interstellar medium: magnetic fields. We report ALMA 1.2 mm, high-resolution (700 au) dust polarization and molecular line observations of the rotating hot molecular core embedded in the high-mass star-forming region IRAS 18089-1732. The dust continuum emission and magnetic field morphology present spiral-like features resembling a whirlpool. The velocity field traced by the H13CO+ (J=3-2) transition line reveals a complex structure with spiral filaments that are likely infalling and rotating, dragging the field with them. We have modeled the magnetic field and find that the best model corresponds to a weakly magnetized core with a mass-to-magnetic-flux ratio (lambda) of 8.38. The modeled magnetic field is dominated by a poloidal component, but with an important contribution from the toroidal component that has a magnitude of 30% of the poloidal component. Using the Davis-Chandrasekhar-Fermi method, we estimate a magnetic field strength of 3.5 mG. At the spatial scales accessible to ALMA, an analysis of the energy balance of the system indicates that gravity overwhelms turbulence, rotation, and the magnetic field. We show that high-mass star formation can occur in weakly magnetized environments, with gravity taking the dominant role.

description: Operating effectively in complex environments while complying with specified constraints is crucial for the safe and successful deployment of robots that interact with and operate around people. In this work, we focus on generating long-horizon trajectories that adhere to novel static and temporally-extended constraints/instructions at test time. We propose a data-driven diffusion-based framework, LTLDoG, that modifies the inference steps of the reverse process given an instruction specified using finite linear temporal logic ($\text{LTL}_f$). LTLDoG leverages a satisfaction value function on $\text{LTL}_f$ and guides the sampling steps using its gradient field. This value function can also be trained to generalize to new instructions not observed during training, enabling flexible test-time adaptability. Experiments in robot navigation and manipulation illustrate that the method is able to generate trajectories that satisfy formulae that specify obstacle avoidance and visitation sequences.

description: An important aspect of computational fluid dynamics is related to the determination of the fluid pressure in isothermal incompressible fluids. In particular this concerns the construction of an exact evolution equation for the fluid pressure which replaces the Poisson equation and yields an algorithm which is a Poisson solver, i.e., it permits to time-advance exactly the same fluid pressure \textit{without solving the Poisson equation}% . In fact, the incompressible Navier-Stokes equations represent a mixture of hyperbolic and elliptic pde's, which are extremely hard to study both analytically and numerically. In this paper we intend to show that an exact solution to this problem can be achieved adopting the approach based on inverse kinetic theory (IKT) recently developed for incompressible fluids by Ellero and Tessarotto (2004-2007). In particular we intend to prove that the evolution of the fluid fields can be achieved by means of a suitable dynamical system, to be identified with the so-called Navier-Stokes (N-S) dynamical system. As a consequence it is found that the fluid pressure obeys a well-defined evolution equation. The result appears relevant for the construction of Lagrangian approaches to fluid dynamics.

Monetary policy and financial markets: regime switches in US short-term interest rates and stock prices. A Markov-switching VAR approach
Creators: name: Ghiani, Giulia
Publisher: name: IMT Alti Studi Lucca
Year: 2014
Subjects: HB Economic Theory

description: This thesis presents a structural framework which accounts for two well-established empirical relationships.
The first is a short term interest rate equation that relates the same variables of a Taylor rule and that is derived as a dynamic equilibrium condition from
an intertemporal Euler equation within a cash-in-advance economy. The second is a stock market equilibrium equation that resembles the so-called "Fed model"
and that is derived as a no-arbitrage condition. The aim of this thesis is to analyse regime shifts in the stochastic processes generating the short term interest
rate and the stock price modelling regime shifts into the cointegrated VAR, so by estimating a Markov-switching vector error correction model with monthly data
(1960-2012) for the US. A second point concerns the linkages between monetary policy and the stock market. This issue is analyzed by investigating endogenous
regime shifts in a cointegrated VAR that models jointly the monetary equilibrium condition and the assets market equilibrium, exploring co-breaking between the two relationships.

description: We analyze the pinning of vortices for a stationary rotating dipolar supersolid along the low-density paths between droplets as a function of the rotation frequency. We restrict ourselves to the stationary configurations of vortices with the same symmetry as that of the array of droplets. In particular, such an analysis clearly reveals that vortices are not only pinned at local density minima, but instead their coordinates are smooth functions of the rotation frequency. Our approach to explaining such a behavior exploits the fact that the wave function of each rotating droplet acquires a linear phase on the coordinates. Hence, the relative phases between the nearest neighboring droplets allow us to predict the position of the vortices in the intermediate low-density region. Here, we show that for a droplet distribution forming a triangular lattice, the phases of three neighboring droplets are needed for the correct description of the vortex location. In particular, for our confined system, we demonstrate that the estimate accurately reproduces the extended Gross-Pitaevskii results in the spatial regions where the neighboring droplets are well-defined.
The slope of the low energy spectrum of Gamma-Ray Burst prompt emission

description: Gamma-ray Bursts (GRBs) prompt emission spectra are often fitted with the empirical ''Band" function, namely two power laws smoothly connected. The typical slope of the low energy (sub-MeV) power law is $α_{B}\simeq -1$. In a small fraction of long GRBs this power law splits into two components such that the spectrum presents, in addition to the typical $\sim$ MeV $νF_ν$ peak, a break at the order of a few keV or hundreds keV. The typical power law slopes below and above the break are -0.6 and -1.5 respectively. If the break is a common feature, the value of $α_{B}$ could be an ''average'' of the spectral slopes below and above the break in GRBs fitted with Band function. We analyze the spectra of 27 (9) bright long (short) GRBs detected by the Fermi satellite finding a low energy break between 80 keV and 280 keV in 12 long GRBs, but in none of the short events. Through spectral simulations we show that if the break is moved closer (farther) to the peak energy a relatively harder (softer) $α_{B}$ is found by fitting the simulated spectra with the Band function. The hard average slope $α_{B}\simeq-0.38$ found in short GRBs suggests that the break is close to the peak energy. We show that for 15 long GRBs best fitted by the Band function only, the break could be present, but it is not identifiable in the Fermi/GBM spectrum, because either at low energies, close to the detector limit for relatively soft $α_{B}\lesssim-1$, or in the proximity of the energy peak for relatively hard $α_{B}\gtrsim-1$. A spectrum with two breaks could be typical of GRB prompt emission, though hard to identify with current detectors. Instrumental design such that conceived for the THESEUS space mission, extending from 0.3 keV to several MeV and featuring a larger effective area with respect to Fermi/GBM, can reveal a larger fraction of GRBs with a spectral energy break.

description: Quantum spin transport is studied in an interacting quantum dot. It is found that a conductance "plateau" emerges in the non-linear charge conductance by a spin bias in the Kondo regime. The conductance plateau, as a complementary to the Kondo peak, originates from the strong electron correlation and exchange processes in the quantum dot, and can be regarded as one of the characteristics in quantum spin transport.

description: Embedded systems are playing an increasingly important role in control engineering. Despite their popularity, embedded systems are generally subject to resource constraints and it is therefore difficult to build complex control systems on embedded platforms. Traditionally, the design and implementation of control systems are often separated, which causes the development of embedded control systems to be highly time-consuming and costly. To address these problems, this paper presents a low-cost, reusable, reconfigurable platform that enables integrated design and implementation of embedded control systems. To minimize the cost, free and open source software packages such as Linux and Scilab are used. Scilab is ported to the embedded ARM-Linux system. The drivers for interfacing Scilab with several communication protocols including serial, Ethernet, and Modbus are developed. Experiments are conducted to test the developed embedded platform. The use of Scilab enables implementation of complex control algorithms on embedded platforms. With the developed platform, it is possible to perform all phases of the development cycle of embedded control systems in a unified environment, thus facilitating the reduction of development time and cost.

Not to seek gold but to paint : the British Columbian views of William G.R. Hind
Creators: name: Fleming, Marnie Lynn
Publisher: name: University of British Columbia
Year: 2010

description: In order to make more meaningful sense of William G.R. Hind's achievements, this thesis will consider a number of different issues. First of all, there is the vital question of Hind's relationship to the artistic milieu of Victorian England from which he emerged. In terms of both style and choice of subject matter his work bears obvious similarities to the products of contemporary English realism. The implications of Hind's allegiance to British trends must be examined. The first chapter will concern itself with the aspirations and attitudes characteristic of Victorian British art which are most relevant to Hind's personal development. An examination of British artistic and social criticisms will provide the background necessary for a fuller comprehension of Hind's insistence on the contemporary subject, particularly the theme of the labourer and his accomplishments. The second chapter will deal with the idea of British imperialism and emigration, issues with which Hind was directly concerned. As a further step in this investigation, the role of the pictorial illustrator, along with an analysis of British and Canadian attitudes toward British Columbia as expressed in books and periodicals will be discussed. The final chapter will concern itself with Hind's British Columbian images and what they tell us about his ideology and background as a product of mid nineteenth century England. Such an approach to William G.R. Hind will make it possible for us to understand his work better within a broad social and artistic milieu.

description: The gyrokinetic description of particle dynamics faces a basic difficulty when a special type of canonical variables is sought, i.e., the so-called \textit{gyrokinetic canonical variables}. These are defined in such a way that two of them are respectively identified with the gyrophase-angle, describing the fast particle gyration motion around magnetic field lines, and its canonically conjugate momentum. In this paper we intend to discuss the conditions of existence for these variables.
