On the modulation instability development in optical fiber systems
Creators: name: Agafontsev, Dmitry
Publisher: name: arXiv
Year: 2010
Subjects: subject: Pattern Formation and Solitons (nlin.PS)
subject: FOS: Physical sciences

description: Extensive numerical simulations were performed to investigate all stages of modulation instability development from the initial pulse of pico-second duration in photonic crystal fiber: quasi-solitons and dispersive waves formation, their interaction stage and the further propagation. Comparison between 4 different NLS-like systems was made: the classical NLS equation, NLS system plus higher dispersion terms, NLS plus higher dispersion and self-steepening and also fully generalized NLS equation with Raman scattering taken into account. For the latter case a mechanism of energy transfer from smaller quasi-solitons to the bigger ones is proposed to explain the dramatical increase of rogue waves appearance frequency in comparison to the systems when the Raman scattering is not taken into account.

description: Hydrodynamic simulations predict that a significant fraction of the gas in the current Universe is in the form of high temperature, highly ionized plasma emitting and absorbing primarily in the soft X-ray and UV bands, dubbed the Warm-Hot Intergalactic Medium (WHIM). Its signature should be observable in red-shifted emission and absorption lines from highly ionized elements. To determine the expected WHIM emission in the soft X-ray band we used the output of a large scale hydrodynamic SPH simulation to generate images and spectra with angular resolution of 14'' and energy resolution of 1 eV. The current biggest limit of any hydrodynamic simulation in predicting the X-ray emission comes from metal diffusion. In our investigation, by using four different models for the WHIM metallicity we have found a strong dependence of the emission on the model used, with differences up to almost an order of magnitude. For each model we have investigated the redshift distribution and angular scale of the emission, confirming that most photons come from redshift z<1.2 and that the emission has a typical angular scale of less than a few arcminutes. We also compared our simulations with the few currently available observations and found that, within the variation of the metallicity models, our predictions are in good agreement with current constraints on the WHIM emission, and at this time the weak experimental constraints on the WHIM emission are not sufficient to exclude any of the models used.

title: Changing images of Margaret Thatcher
Creators: name: Critchell, Cecile
Publisher: name: University of Kent
Year: 2021

description: This thesis concerns the changing images of Mrs Thatcher presented in the press during the general election campaigns of 1979, 1983 and 1987. These benchmarks were arguably the times when the most diverse and concentrated verbal and visual images appeared. From 1979 onwards the nature of Conservative campaigns changed significantly. The public became 'consumers' of politics. A brand leader with style and personality became a necessity in the marketing operation. The presedential-style election campaign was relentlessly pursued by the Conservative Party, with media support and sometimes connivance. This helped to alter the content of media election news. The Press reported the new-style events in a partisan manner, using a variety of verbal and visual imagery to support, explain and criticise Mrs Thatcher and her leadership. Mrs Thatcher was not the first Party Leader or Prime Minister to be specially tutored and packaged for media presentation. She was, however, the first to use the media so extensively as an integral part of her personal campaign at general elections. She lent herself completely to the image development deemed necessary by her advisors. The concern here is not to develop a theory of images, but to focus on Mrs Thatcher's Premiership, personality and recent history. The work opens with a discussion of the notion of image and the particular way it is used. This use is then related to the verbal images found in selected articles, features and editorials, and the visual images drawn from cartoons and photographs at three chosen general elections. Factors which influenced the changes of image at particular times or for special reasons feature in the various related lines of enquiry. Influential colleagues and people who advised on presentation of the personality, central to the presidential-style campaigns, are also included. The results of the analysis show that in 1979 many of the images were imprecise and not particularly critical since Mrs Thatcher was a contender for Premiership and not a previous incumbent. By 1987 very significant changes appear in the images, due to her length of time in office and her style of leadership. The analysis also revealed the range and diversity of images used. It becomes plain, not only how striking are the differences in the way Mrs Thatcher is portrayed, but how much she contributed to the process, and thus to her own image.

description: The focus of this paper is on reducing the complexity in verification by exploiting modularity at various levels: in specification, in verification, and structurally. For specifications, we use the modular language CSP-OZ-DC, which allows us to decouple verification tasks concerning data from those concerning durations. At the verification level, we exploit modularity in theorem proving for rich data structures and use this for invariant checking. At the structural level, we analyze possibilities for modular verification of systems consisting of various components which interact.We illustrate these ideas by automatically verifying safety properties of a case study from the European Train Control System standard, which extends previous examples by comprising a complex track topology with lists of track segments and trains with different routes.

description: We study the coherent quantum evolution of a closed and driven mesoscopic chain of two-level systems that interact via the van-der-Waals interaction in their excited state. The Hamiltonian consists of a part corresponding to a classical lattice gas and an off-diagonal driving term without classical counterpart. We show that in a certain parameter range the latter leads to a thermalization of the system with respect to observables of the classical lattice gas such as the interaction energy and particle number distribution. We investigate the evolution of the system into this thermal state and discuss how to determine the corresponding temperature. Our findings can be applied to understand thermalization in strongly interacting systems of laser-driven Rydberg atoms, ions or polar molecules.

description: This talk gives an overview, aimed at non-experts, of the recent progress on the studies of technicolor models on the lattice. Phenomenologically successful technicolor models require walking coupling; thus, an emphasis is put on the determination of the beta-function of various models. As a case study we consider SU(2) gauge field theory with two adjoint representation fermions, so-called minimal walking technicolor theory.

description: Un fenomeno legato ad un mondo che oggi giorno è sempre più diffuso, quello dei “techno party”. Un ambiente in cui sul piano psicologico, la musica influisce sulla percezione del proprio essere, definendo lo spazio in cui un soggetto si trova. Negli ultimi anni la musica elettronica, ma in particolare quella techno, è diventata un genere sempre più diffuso e apprezzato dai giovani tra i 16 e i 30 anni, tanto da coinvolgere veri e propri appassionati. Questi eventi però, per molti partecipanti costituiscono semplicemente un luogo di svago e divertimento, attraverso veri e propri momenti di “evasione dalla realtà”. Infatti, un altro aspetto che emerge sempre più tra i partecipanti è caratterizzato dall’assunzione di sostanze stupefacenti, che, interagendo con tale musica, inducono ad uno stato alterato della coscienza. Seppure sempre più diffusa, la cultura della musica elettronica, soprattutto la techno, si discosta da quella cosiddetta commerciale o “mainstream”, anche se la maggior parte degli strumenti d’informazione utilizzati per trattare l’argomento sono codificati secondo dei modelli molto più affini a quest’ultima. Strumenti che utilizzano un linguaggio e dei contenuti di tipo tecnico musicale, incentrati sulla figura del dj e sull’aspetto strumentale, portando un numero di fruitori piuttosto limitato. Da qui deriva la necessità di approfondire le origini del fenomeno, i simboli e i suoi linguaggi, attraverso un approccio più intimo ed esperienziale, riferito all’aspetto percettivo della persona.

to argue that a substantial part of the well-known word-order correlations is best

explained by grammaticalisation processes. Functional-adaptive accounts in terms

of processing or learning constraints are currently weakly substantiated, and they

suffer from the fact that they do not adequately control for language-internal inher-

itance patterns. More generally, historical relatedness between different types of

phrases constitutes an important confound in typological research, one that needs

to be taken seriously before word-order correlations are motivated by anything

other than the diachronic patterns that link the word order pairs in question.

description: Lo scopo di questo lavoro di ricerca, prettamente qualitativa, è quello di capire come evolvono le rappresentazioni di un solido dopo un percorso mirato a far sviluppare questa capacità. Per permettere ai bambini di diventare abili nel disegnare un oggetto tridimensionale sono stati ideati sei interventi. In questi gli allievi sono stati chiamati a costruire delle strutture di cubi partendo da fotografie (in gruppo o singolarmente), a disegnarle da un punto di vista assegnato oppure a disegnarle immaginando punti di vista diversi da quello conosciuto. Il percorso è stato analizzato mettendo a confronto i disegni fatti nel primo intervento con quelli svolti nell’ultimo, poiché entrambi sono stati eseguiti nella stessa situazione con la struttura di cubi. Da questo paragone è emerso che tutti i bambini, durante il percorso, hanno avuto la possibilità di migliorare sia le rappresentazioni realizzate dal punto di vista conosciuto sia quelle realizzate a partire da un punto di vista immaginato. I disegni finali risultano molto più coerenti e fedeli al modello, poiché raffigurano la struttura in proiezione ortogonale con l’aggiunta della profondità dove visibile. In conclusione si può dunque affermare che le attività svolte sono risultate efficaci per il raggiungimento dell’obiettivo inizialmente posto, e che la ricerca, grazie alla definizione di alcuni criteri di analisi, ha permesso di evidenziare in maniera più fine l’evoluzione delle rappresentazioni realizzate.

description: Image distortion due to weak gravitational lensing is examined using a non-perturbative method of integrating the geodesic deviation and optical scalar equations along the null geodesics connecting the observer to a distant source. The method we develop continuously changes the shape of the pencil of rays from the source to the observer with no reference to lens planes in astrophysically relevant scenarios. We compare the projected area and the ratio of semi-major to semi-minor axes of the observed elliptical image shape for circular sources from the continuous, thick-lens method with the commonly assumed thin-lens approximation. We find that for truncated singular isothermal sphere and NFW models of realistic galaxy clusters, the commonly used thin-lens approximation is accurate to better than 1 part in 10^4 in predicting the image area and axes ratios. For asymmetric thick lenses consisting of two massive clusters separated along the line of sight in redshift up to Δz = 0.2, we find that modeling the image distortion as two clusters in a single lens plane does not produce relative errors in image area or axes ratio more than 0.5%

Optical methods for rapid quantitative analysis of bitumen content in oil sands
Creators: name: Zhang, Yingyue
Publisher: name: University of British Columbia
Year: 2024

description: Proven oil reserves in Canada are estimated at 170 billion barrels, of which 160 billion barrels are oil sands located in Alberta. Oil sands are the remnants of degraded conventional oils mixed with large proportions of sand. The bitumen content in typical oil sands may vary from 1% to 18%. To reduce the energy and water consumption in the extraction process, one of the most important parameters for oil sands production is the bitumen content in the ore, but very few techniques are available for online monitoring of the bitumen content in oil sands. The objective of this study is to develop optical techniques for rapid monitoring of the bitumen content in oil sands. A high-speed optical scanner in combination with a telescope was built to measure the bitumen content in oil sands using the scattered light intensity and fluorescence signal from oil sands. The bitumen contents were determined with a good signal-to-noise ratio, and 2D bitumen content maps were obtained. Compared to commercial near infrared reflectance ore analyzers, this new method is insensitive to the water content and the background light intensity. The possibility of using Raman scattering for bitumen content measurements was also investigated. Although qualitative analysis was possible, quantitative analysis was difficult because of the relatively weak signal and spot-dependence.

description: The huge surge in migration into the European Union, particularly over the last two years, has revealed the inadequacy of the current legal framework. The Dublin III Regulation, which establishes the criteria and mechanisms for determining the Member State responsible for examining an application for international protection lodged in one of the Member States by a third-country national or a stateless person, now appears outdated. The initiatives devised by the European Commission to alleviate the burdens on the countries most exposed, activating for the first time the emergency mechanism under Art. 78, para. 3, TFEU, have proven to be largely ineffective and have faced stiff opposition from various Member States on both political and legal grounds. The resettlement programme introduced to ensure safe and legal access into the European Union has also failed to achieve the desired results. The debate has now turned to how to overcome the limitations of the current system. The European Agenda on Migration presented in May 2015 proposed the establishment of a single asylum decision process, to guarantee equal treatment of asylum seekers throughout Europe, and a mechanism for mutual recognition of positive asylum decisions. The European Commission now seems set to develop a relocation mechanism based on a distribution key. The new system must nonetheless ensure a fairer sharing of responsibility while guaranteeing effective solidarity between Member States and respect for the fundamental rights of people.

description: Reliable modeling of the atmospheres of cool white dwarfs is crucial for understanding the atmospheric evolution of these stars and for accurate white dwarfs cosmochronology. Over the last decade {\it ab initio} modeling entered many research fields and has been successful in predicting properties of various materials under extreme conditions. In many cases the investigated physical regimes are difficult or even impossible to access by experimental methods, and first principles quantum mechanical calculations are the only tools available for investigation. Using modern methods of computational chemistry and physics we investigate the atmospheres of helium-rich, old white dwarfs. Such atmospheres reach extreme, fluid like densities (up to grams per cm$^3$) and represent an excellent laboratory for high temperature and pressure physics and chemistry. We show our results for the stability and opacity of $\rm H^-$ and $\rm C_2$ in dense helium and the implications of our work for understanding cool white dwarfs.

Grammaticalization accounts of word order correlations

description: This paper examines the role that grammaticalization plays in explaining word order correlations. It presents some data that only grammaticalization accounts for, but also argues that there are correlations that grammaticalization does not account for. The conclusion is that accounts entirely in terms of grammaticalization or accounts that make no reference to grammaticalization are both inadequate.
Hole subband mixing and polarization of luminescence from quantum dashes: a simple model

description: In this paper, we address the problem of luminescence polarization in the case of nanostructures characterized by an in-plane shape asymmetry. We develop a simple semi-qualitative model revealing the mechanism that accounts for the selective polarization properties of such structures. It shows that they are not a straightforward consequence of the geometry but are related to it via valence subband mixing. Our model allows us to predict the degree of polarization (DOP) dependence on the in-plane dimensions of investigated structures assuming a predominantly heavy hole character of the valence band states, simplifying the shape of confining potential and neglecting the influence of the out-of plane dimension. The energy dependence modeling reveals the importance of different excited states in subsequent spectral ranges leading to non-monotonic character of the DOP. The modeling results show good agreement with the experimental data for an ensemble of InAs/InP quantum dashes for a set of realistc parameters with the heavy-light hole states separation being the only adjustable one. All characteristic features are reproduced in the framework of the proposed model and their origin can be well explained and understood. We also make some further predictions about the influence of both the internal characteristics of the nanostructures (e.g. height) and the external conditions (excitation power, temperature) on the overall DOP.

description: Background: The mu-opioid agonist methadone is administered orally and used in opioid detoxification and in the treatment of moderate-to-severe pain. Acute oral methadone–use and –abuse have been associated with inflammatory and toxic central nervous system (CNS) damage in some cases and cognitive deficits can develop in long-term methadone users. In contrast, reports of intravenous methadone adverse effects are rare. Case presentation: Here, we report a patient who developed acute bilateral hearing loss, ataxia and paraparesis subsequently to intravenous methadone-abuse. While the patient gradually recovered from these deficits, widespread magnetic resonance imaging changes progressed and delayed-onset encephalopathy with signs of cortical dysfunction persisted. This was associated with changes in the composition of monocyte and natural killer cell subsets in the cerebrospinal fluid. Conclusion: This case suggests a potential bi-phasic primary toxic and secondary inflammatory CNS damage induced by intravenous methadone.

description: We have realized a compact system to efficiently couple the fluorescent light emitted by a single trapped ion to two opposing optical fibers. The fibers are tightly integrated in the center electrodes of a miniature endcap trap. They capture light from the ion with a numerical aperture of 0.34 each, corresponding to 6% of the solid angle in total. The high collection efficiency and high signal-to-background ratio make the setup an ideal quantum light source. We have observed strong antibunching of the photons emitted from the two fibers. The system has a range of applications from single-ion state detection in quantum information processing to strong coupling cavity-QED with ions.

description: Five copper(II), zinc(II) and nickel(II) complexes, [Cu2L2(μ1,1-N3)2] (1), [Zn2L2(μ2-η1:η1-CH3COO)(NCS)]EtOH (2), [Zn2L2(μ2-η1:η1-CH3COO)(N3)]MeOH (3), [Zn2Cl2L2] (4) and [NiL(HL)]ClO4 (5), were prepared from the Schiff base 3-methyl-2-((pyridin-2-ylmethylene)amino)phenol (HL). The compounds have been characterized by physico-chemical methods including elemental analysis, IR, and UV–Vis spectra. Structures of the five new complexes were determined by single crystal X-ray diffraction. The copper ions in 1 are in square pyramidal, while zinc ions in 2, 3, and 4 are distorted square pyramidal, and the nickel ions in 5 are octahedral. The biological assay indicated that zinc complex 2 has the most effective activity on Jack bean urease with IC50 = 1.7 ± 0.8 μmol·L−1. Molecular docking was performed to study the interaction between the active center of the urease with molecules of the complexes.

description: It is hard to understand the current developments in European refugee law without the benefit of hindsight. This paper refrains from trying to make a comprehensive analysis, and investigates fragments small enough to allow for analysis. We will look at the political and legal processes which turned the influx of a small number of people into the European Union (EU) into a crisis; at tunnel vision of European policy makers; at the legal aspects of the EU's and NATO's intervention in the Aegean Sea; and at the processes resulting in the acceptance of mass deaths as a daily routine.

description: In this paper, we propose a transfer learning-based methodology that can be exploited for indexing protein structures from associated 3D point clouds. Such a methodology can be particularly useful for biologists that are searching automated solutions to find family members of a query protein or even to label new structures by directly using input raw 3D point clouds. Comparative study and performance evaluation show the efficiency and the potential of the proposed methodology.

description: We introduce a method and an algorithm for computing the weighted Moore-Penrose inverse of multiple-variable polynomial matrix and the related algorithm which is appropriated for sparse polynomial matrices. These methods and algorithms are generalizations of algorithms developed in [M.B. Tasic, P.S. Stanimirovic, M.D. Petkovic, Symbolic computation of weighted Moore-Penrose inverse using partitioning method, Appl. Math. Comput. 189 (2007) 615-640] to multiple-variable rational and polynomial matrices and improvements of these algorithms on sparse matrices. Also, these methods are generalizations of the partitioning method for computing the Moore-Penrose inverse of rational and polynomial matrices introduced in [P.S. Stanimirovic, M.B. Tasic, Partitioning method for rational and polynomial matrices, Appl. Math. Comput. 155 (2004) 137-163; M.D. Petkovic, P.S. Stanimirovic, Symbolic computation of the Moore-Penrose inverse using partitioning method, Internat. J. Comput. Math. 82 (2005) 355-367] to the case of weighted Moore-Penrose inverse. Algorithms are implemented in the symbolic computational package MATHEMATICA.
Contributions of mesenchymal progenitors to permeable vascular interfaces

Publisher: name: University of British Columbia

description: In the choroid plexus (CP) and pituitary gland (PG), blood vessels are known to have a permeable phenotype that allows for the free passage of molecules in contrast to the blood brain barrier that is found in the rest of the CNS. While the endothelium and secretory cells (CP epithelium and PG endocrine cells) of these compartments have been studied in detail, fewer studies have examined the mesenchymal progenitors (MPs, also called pericytes, fibroblasts and mural cells) in these tissues. In this study, the Hic1CreERT2/CreERT2; Rosa26LSL-tdTomato/⁺ (Hic1-tdTom) lineage tracing mouse model was used to examine MPs within the CP and PG. Single-cell RNA-sequencing and reporter gene detection identified and validated distinct patterns of gene expression. We found that permeable brain regions possess substantial populations of distinct Hic1⁺ mesenchymal progenitors that make specific contributions to CP, PG and the meninges by expressing extracellular matrix proteins such as collagen 1 and metabolic enzymes such as Indole-n-methyltransferase. Multiple unique markers of mesenchymal cells in the CP and PG were identified, including ALPL and CD34. In sum, this study has identified and characterized novel populations of Hic1⁺ mesenchymal cells specific to permeable neurovasculature and the meninges.

description: In un contesto competitivo globale come quello all’interno del quale Schindler opera, è fondamentale essere innovativi rispondendo con estrema sensibilità e rapidità alle mutevoli esigenze del cliente, attraverso processi ottimizzati che garantiscano prestazioni d’eccellenza. L’unione di dinamicità, capacità innovativa e cura per il cliente sono alcuni degli ingredienti fondamentali che permettono a Schindler Group di essere leader nel settore della movimentazione di persone con ascensori e scale mobili. Queste necessità vengono ovviamente enfatizzate per i siti produttivi come quello di Locarno che si trova ad operare in un contesto dove i fattori di produzione sono costosi se paragonati ad altre aree geografiche. Proprio per rispondere a queste esigenze d’ottimizzazione, la digitalizzazione ci offre diverse soluzioni per aumentare l’efficienza operativa e l’efficacia dei processi, tra cui l’automazione digitale che è l’oggetto del presente lavoro. Grazie all’implementazione di queste nuove tecnologie, è possibile è aumentare il livello di servizio al cliente, diminuendo le attività ripetitive d’ufficio e focalizzando la capacità produttiva su processi a valore aggiunto. Per approcciare nel modo corretto questa tecnologia e porre le basi nozionistiche e metodologiche, necessarie ad un progetto pilota di successo, Schindler LOC ha proposto questo lavoro di diploma. Partendo dall’analisi dello stato dell’arte della tecnologia, il presente lavoro, sviluppa e propone un modello d’analisi e classificazione dei processi, che permette di definire la fattibilità e la convenienza relativa all’implementazione della tecnologia RPA degli stessi, prendendo in considerazione diversi criteri di valutazione tra cui vi sono aspetti economici, relativi ai costi e benefici e la complessità d’implementazione. A tale scopo si propone un “punteggio d’automazione” complessivo, che ha permesso di identificare la “stampa e preparazione dei documenti di spedizione” e il “monitoraggio del change management”, come processi pilota per la Robotic Process Automation. In seguito alla pianificazione delle attività che il robot digitale dovrà eseguire, si è studiato un modello d’analisi dei costi-benefici che l’azienda utilizzerà, secondo previsioni interne, nella metà del 2019. Questo progetto di diploma ha avuto modo di dimostrare la propria validità tecnica, attraverso l’applicazione ad altri progetti, come la selezione dei fornitori per l’automazione industriale. La fase inziale non sarà solo esplorativa e di accrescimento del know-how, ma porterà all’azienda un risparmio netto di circa 318’000 chf in tre anni, attraverso la sola automazione dei due processi emersi dallo studio.
Downscaling extremes: A comparison of extreme value distributions in point-source and gridded precipitation data

description: There is substantial empirical and climatological evidence that precipitation extremes have become more extreme during the twentieth century, and that this trend is likely to continue as global warming becomes more intense. However, understanding these issues is limited by a fundamental issue of spatial scaling: most evidence of past trends comes from rain gauge data, whereas trends into the future are produced by climate models, which rely on gridded aggregates. To study this further, we fit the Generalized Extreme Value (GEV) distribution to the right tail of the distribution of both rain gauge and gridded events. The results of this modeling exercise confirm that return values computed from rain gauge data are typically higher than those computed from gridded data; however, the size of the difference is somewhat surprising, with the rain gauge data exhibiting return values sometimes two or three times that of the gridded data. The main contribution of this paper is the development of a family of regression relationships between the two sets of return values that also take spatial variations into account. Based on these results, we now believe it is possible to project future changes in precipitation extremes at the point-location level based on results from climate models.
