description: For the Many-Body-Localized phase of random Majorana models, a general Strong Disorder Real-Space Renormalization procedure known as RSRG-X [D. Pekker, G. Refael, E. Altman, E. Demler and V. Oganesyan, Phys. Rev. X 4, 011052 (2014)] is described to produce the whole set of excited states, via the iterative construction of the Local Integrals of Motion (LIOMs). The RG rules are then explicitly derived for arbitrary quadratic Hamiltonians (free-fermions models) and for the Kitaev chain with local interactions involving even numbers of consecutive Majorana fermions. The emphasis is put on the advantages of the Majorana language over the usual quantum spin language to formulate unified RSRG-X rules.

description: The ability to determine the joint spectral properties of photon pairs produced by the processes of spontaneous parametric downconversion (SPDC) and spontaneous four wave mixing (SFWM) is crucial for guaranteeing the usability of heralded single photons and polarization-entangled pairs for multi-photon protocols. In this paper, we compare six different techniques that yield either a characterization of the joint spectral intensity or of the closely-related purity of heralded single photons. These six techniques include: i) scanning monochromator measurements, ii) a variant of Fourier transform spectroscopy designed to extract the desired information exploiting a resource-optimized technique, iii) dispersive fibre spectroscopy, iv) stimulated-emission-based measurement, v) measurement of the second-order correlation function $g^{(2)}$ for one of the two photons, and vi) two-source Hong-Ou-Mandel interferometry. We discuss the relative performance of these techniques for the specific cases of a SPDC source designed to be factorable and SFWM sources of varying purity, and compare the techniques' relative advantages and disadvantages.

description: A betel quid (BQ) chewing habit has been strongly associated with the development of several oral mucosal diseases. In order to investigate whether individual components of BQ mixtures have distinct physio-pathological effects on oral mucosal cells, we examined the impact of areca nut (AN), Piper betle leaf (Leaf), Piper betle stem inflorescence (SI), areca husk (Husk) and the complete BQ mixture on the growth of oral keratinocytes (OKF-6) and primary oral fibroblasts (MMF-1). Based on their known chemical properties, we selected BQ samples from Banda Aceh (BA) and West Papua (WP) regions for our in vitro study. We used a fluorescein diacetate assay (FDA) to assess the cell viability of BQ components on OKF-6 and MMF-1 cells. The cytotoxic effect of WP-AN on the OKF-6 cell line was observed at a concentration of 100 μg/mL, resulting in a 50% reduction in cell viability (IC50) after a 2-day incubation. Similarly, BA-AN exhibited cytotoxic effect, although at a higher concentration (500 μg/mL). WP-SI also displayed cytotoxic effects at a concentration of 500 μg/mL following 2 days of incubation. In contrast, Leaf, BQ mixture and husk extracts did not show any cytotoxic effects even after 3 days of incubation. No cytotoxic effects were observed at any concentration of BQ components when exposed to MMF-1 cells. Regarding cell proliferation, MMF-1 cells exposed to BA-AN and WP-AN showed increased growth on day 1, followed by decreased growth on day 2, in a dose- and time-dependent manner. Overall, our study indicates that BQ components induce distinctive cytotoxic effects on stromal and epithelial cells from the oral cavity.

description: En esta investigación exponemos cómo la justicia de transición enfrenta un conjunto de desafíos, entre ellos, la responsabilidad de neutralizar la cultura de la violencia que todo conflicto de larga duración instaura en las subjetividades y en las instituciones afectadas. La violencia contiene un potencial mimético a través del cual contamina las subjetividades e instituciones. Ese potencial mimético de la violencia tiende a reproducirla normalizada como si fuese un valor natural o un comportamiento institucional legítimo. Aparentes soluciones, como las políticas de olvido, tienden a recalcar la mímesis de la violencia bajo falsas apariencias de superación, posibilitando que la potencia mimética de la violencia se replique de otras formas en las subjetividades e instituciones con nuevos brotes de violencias. El medio para superar la mímesis de la violencia y posibilitar políticas efectivas de una justicia de transición, es confrontar la violencia con la memoria de las víctimas. La memoria tiene una potencia anamnética que actualiza el pasado con nuevos significados para el presente. El diálogo restaurativo repone la memoria sufrida por las víctimas como referente ético para elaborar estrategias de neutralización de la mímesis violenta y con ello posibilitar una más efectiva justicia de transición.
description: In this investigation we show how the transitional justice faces a set of challenges, among them, the responsibility to neutralize the culture of violence that every long-term conflict establishes in the affected subjectivities and institutions. Violence contains a mimetic potential through which it contaminates subjectivities and institutions. This mimetic potential of violence tends to reproduce it normalized as if it was a natural value or legitimate institutional behavior. Apparent solutions, such as the politics of oblivion, tend to repress the mimesis of violence under false appearances of overcoming it, enabling the mimetic power of violence to be replicated in other ways in subjectivities and institutions with new outbreaks of violence. The means to overcome the mimesis of violence and enable effective transitional justice policies is to confront violence with the memory of the victims. Memory has an anamnetic power that updates the past with new meanings for the present. The restorative dialogue restores the memory suffered by the victims as the ethical reference to devise strategies to neutralize violent mimesis and to enable a more effective transitional justice.

title: Multiplexed visible light communication systems using GaN-based sources
Creators: name: Viola, Shaun
Publisher: name: University of Glasgow

Subjects: subject: Optical communication, visible light communication, GaN, multiplexing.

description: With the emergence of efficient semiconductor solid state lighting a new application space has emerged for communications, namely visible light communications (VLC). The high speed modulation capabilities of Gallium Nitride (GaN) based LEDs and laser diodes means these devices have the potential to supplement or replace existing radio wave standards such as Wifi, as well as creating new applications for optical communications such as underwater VLC. Given the ever increasing demand for information in modern society, it is desirable to continually increase the bandwidth capabilities of communication systems through both exploration of unused frequency spectrum, like the visible spectrum, and also the application of existing and developing multiplexing techniques. This thesis will focus on the investigation of quadrature amplitude modulation (QAM) based orthogonal frequency division multiplexing (OFDM) as applied to GaN based sources in various VLC systems. In this thesis investigation of complex modulation formats and advanced multiplexing techniques applied to novel m-LED devices has shown VLC system bandwidths of up to 655 MHz and data rates of up to 7.91 Gbit/s which, to the authors knowledge, is the highest data rate achieved using a single m-LED pixel for data transmission. The laser based VLC systems shown in this thesis have utilised both the simplest form of baseband modulation on off keying (OOK) as well as QAM based OFDM. These systems, at the time of publication, demonstrated the highest data rate achieved for each of these modulation types using commercially available devices. In addition to multiplexing using orthogonal frequencies the implementation of spatial multiplexing has become an area of great interest for free-space optical (FSO) communication links, particularly for its use in last-mile links within larger optical networks. Light carrying orbital angular momentum (OAM) has emerged as a potential candidate that could be utilised for multiplexing independent channels. The feasability of OAM multiplexing underwater has been investigated through analysis of inter-channel crosstalk for a set of 11 OAM modes propagating through 3 m of slowly flowing water, similar to that found in Oceanic conditions. At publication this was the first investigation of its kind where crosstalk effects induced by flowing water were measured.

description: Under the assignment of $a_0(1450)$ as the ground isovector scalar meson, the strong decays of $a_0(1950)$ and $a_0(2020)$ are evaluated in the $^3P_0$ model. Our calculations suggest that $a_0(1950)$ and $a_0(2020)$ can be regarded as the same resonance referring to $a_0(3^3P_0)$. The masses and strong decays of $a_0(2^3P_0)$ and $a_0(4^3P_0)$ are also predicted, which can be useful in the search for radially excited scalar mesons in the future.

Hard-to-abate sector

description: The hard-to-abate transportation sectors have a considerable share of overall GHG emissions. In particular, the aviation sector accounts for 2.5% of global anthropogenic CO2 emissions and is expected to grow further [1]. Decarbonisation of such sectors is currently high on the agenda in the European Union and its member states. The emissions associated with the aviation sector are anticipated to grow considerably, with possible increase across Germany as well as Europe. Mitigating such emissions requires deliberate efforts and planned interventions. Alternative fuels based on renewable electricity and new propulsion technologies can play a key role in the transition towards CO2-neutral, hard-to-abate transport sectors. Production and synthesis of such fuels are usually energy intensive process that requires substantially high electricity and higher penetration of renewable energy sources in the system. In this paper, two scenarios have been analysed by developing an agent based model to simulate the technology diffusion process. To systematically investigate the process considering a data driven bottom up approach, techno-economic, environmental, regulatory and infrastructural uncertainties were incorporated to represent the complexities of this sector. Model simulations gave multiple possibilities regarding the energy demand, the outputs of which were then compared with reference scenarios. Our findings show that the additional electricity demand in 2050 to decarbonise the aviation sector in Germany, is approximately 4 TWh via biological route, whereas using non-biological route the demand increased up to 109 TWh, resulting in a relative CO2 emission mitigation of roughly 58 %.

description: Recent STAR data on the bulk observables in the energy range of the Beam-Energy Scan Program at the Relativistic Heavy-Ion Collider are analyzed within the model of the three-fluid dynamics (3FD). The simulations are performed with different equations of state (EoS). The purely hadronic EoS fails to reproduce the data. A good, though imperfect, overall reproduction of the data is found within the deconfinement scenarios. The crossover EoS turns out to be slightly preferable. For this reproduction a fairly strong baryon stopping in the quark-gluon phase is required. The 3FD model does not need two separate freeze-outs (i.e. kinetic and chemical ones) to describe the STAR data. A unified freeze-out is applied at all energies.

description: We study a Hamiltonian describing a pendulum coupled with several anisochronous oscillators, devising an asymptotic expansion for the splitting (matrix) associated with a homoclinic point. This expansion consists of contributions that are manifestly exponentially small in the limit of vanishing hyperbolicity, by a shift-of-contour argument. Hence, we infer a similar upper bound on the splitting itself.

description: Fundamental research and technological applications of topological insulators are hindered by the rarity of materials exhibiting a robust topologically non-trivial phase, especially in two dimensions. Here, by means of extensive first-principles calculations, we propose a novel quantum spin Hall insulator with a sizeable band gap of $\sim$0.5 eV that is a monolayer of Jacutingaite, a naturally occurring layered mineral first discovered in 2008 in Brazil and recently synthesised. This system realises the paradigmatic Kane-Mele model for quantum spin Hall insulators in a potentially exfoliable two-dimensional monolayer, with helical edge states that are robust and that can be manipulated exploiting a unique strong interplay between spin-orbit coupling, crystal-symmetry breaking and dielectric response.

description: Die Stromerzeugung aus dezentralen Anlagen erneuerbarer Energien (EE) und der erzeugungs-nahe Stromverbrauch aus diesen EE-Anlagen vor dem Netzanschlusspunkt („Prosuming“) sind ein unverzichtbarer Baustein der deutschen Energiewende. Sie ermöglichen einerseits die wirt-schaftliche Teilhabe einer Vielzahl privater und gewerblicher Akteure an der Transformation der deutschen Wirtschaft hin zur Klimaneutralität. Andererseits können sie auch dazu beitragen, den Naturflächenverbrauch des für diese Transformation notwendigen EE-Ausbaus in Grenzen zu halten. Vor allem können durch Prosuming stromverbrauchsnahe Flächen in Ballungszentren für die EE-Stromerzeugung erschlossen werden, die ansonsten nicht verfügbar wären. Aus diesem Grund bergen Prosuming-Anwendungen auch die Chance, den Netzausbaubedarf erheblich zu reduzieren. Außerdem tragen sie zu einer zunehmenden Kopplung und Elektrifizierung anderer Sektoren bei, deren Energieträger schwieriger zu dekarbonisieren sind als Strom. Angesichts der neuen Ziele der Ampel-Koalition hinsichtlich des EE-Ausbaus sowie der Sekto-renkopplung in 2030, stellt sich die Frage, inwiefern und unter welchen Voraussetzungen Pro-suming einen Beitrag zur Erreichung dieser Ziele leisten kann. Denn je mehr EE-Zubau bspw. über Prosuming-Anwendungen generiert werden kann, desto geringer dürfte der Ausschrei-bungs- und Förderbedarf für große EE-Parks ausfallen, um ebenjene Ziele zu erreichen. In dieser Studie werden diese Fragestellungen untersucht, indem ein breites Feld an Prosuming-Anwendungsfällen bezüglich ihrer Mengenpotentiale, Wirtschaftlichkeit und volks- wie energie-wirtschaftlicher Vorteile analysiert wird. Auf dieser Basis lassen sich Vorschläge für regulatori-sche Rahmenbedingungen ableiten, die die Wirtschaftlichkeit der Anwendungsfälle und damit die Ausschöpfung der Potentiale verbessern können. Nachfolgend werden die Kernergebnisse der Studie dargestellt.

description: We study the electron dynamics at a monocrystalline Pd(111) surface with stepped vicinal nanostructures modeled in a simple Kronig-Penney scheme. The unoccupied bands of the surface are resonantly excited \textit{via} the resonant charge transfer (RCT) interaction of the surface with a hydrogen anion reflected at grazing angles. The interaction dynamics is simulated numerically in a quantum mechanical wave packet propagation approach. Visualization of the wave packet density shows that, when the electron is transferred to the metal, the surface and image subband states are the most likely locations of the electron as it evolves through the superlattice. The survival probability of the interacting ion exhibits strong modulations as a function of the vicinal-terrace size and shows peaks at those energies that access the image state subband dispersions. A simple square well model producing standing waves between the steps on the surface suggests the application of such ion-scattering at shallow angles to map electronic substructures in vicinal surfaces. The work also serves as the first proof-of-principle in the utility of our computational method to address, via RCT, surfaces with nanometric patterns.

description: Time-resolved observations of brown dwarfs' rotational modulations provide powerful insights into the properties of condensate clouds in ultra-cool atmospheres. Multi-wavelength light curves reveal cloud vertical structures, condensate particle sizes, and cloud morphology, which directly constrain condensate cloud and atmospheric circulation models. We report results from Hubble Space Telescope/Wide Field Camera 3 near-infrared G141 taken in six consecutive orbits observations of HN Peg B, an L/T transition brown dwarf companion to a G0V type star. The best-fit sine wave to the $1.1-1.7μ$m broadband light curve has the amplitude of $1.206\pm0.025\%$ and period of $15.4\pm0.5$ hr. The modulation amplitude has no detectable wavelength dependence except in the 1.4 $μ$m water absorption band, indicating that the characteristic condensate particle sizes are large ($>1μ$m). We detect significantly ($4.4σ$) lower modulation amplitude in the 1.4$μ$m water absorption band, and find that HN Peg B's spectral modulation resembles those of early T type brown dwarfs. We also describe a new empirical interpolation method to remove spectral contamination from the bright host star. This method may be applied in other high-contrast time-resolved observations with WFC3.

description: We present experiments in which the interaction of a single gold nanoparticle with glass substrates or with another gold particle can be tuned by in-situ control of their separations using scanning probe technology. We record the plasmon resonances of the coupled systems as a function of the polarization of the incident field and the particle position. The distinct spectral changes of the scattered light from the particle pair are in good agreement with the outcome of finite difference time-domain (FDTD) calculations. We believe our experimental technique holds promise for the investigation of the van der Waals-Casimir type interactions between nanoscopic neutral bodies.

The aim of the present study was to test whether raspberry ketone and green coffee bean extract, when consumed separately and in combination, affect substrate utilisation and body composition. In a single blind randomised control trial, 32 healthy recreationally active males and females (age: 30.4 ± 1.5 years; BMI: 26.7 ± 0.4 kg.m-2; body mass: 79.0 ± 1.8 kg; V̇O2max: 37.7 ± 1.4 ml.kg-1.min-1) were randomly assigned to four different treatment groups for 8 weeks; raspberry ketone (RK) (200 mg/day), green coffee bean extract (CGE) (400 mg/day), raspberry ketone plus green coffee bean extract (RK+CGE) (200 mg/day plus 400 mg/day) or control (200 mg/day). Resting metabolic rate, anthropometry, body composition and metabolic responses during a 30-minute steady state exercise test (55% V̇O2max) were measured at baseline and repeated post intervention. There was no effect of either supplement alone, or in combination on body mass (Baseline vs post intervention - RK: 82.5 ± 3.8 vs 81.6 ± 3.9, CGE: 81.1 ± 3.0 vs 81.0 ± 3.2, RK+CGE: 75.9 ± 3.8 vs 74.5 + 4.0, Control: 76.7 ± 4.1 vs 76.3 ± 4.2kg (p>0.05)) or body fat (Baseline vs post intervention - RK: 25.6 ± 3.3 vs 25.9 ± 2.7, CGE: 28.2 ± 4.3 vs 28.7 ± 4.2, RK+CGE: 33.0 ± 3.8 vs 32.4 ± 3.7, Control 25.8 ± 3.6 vs 25.8 ± 3.3% (p>0.05)). Similarly, no effect on substrate utilisation was observed either at rest (Baseline vs post intervention RER - RK: 0.83 ± 0.02 vs 0.84 ± 0.01, GCE: 0.84 ± 0.02 vs 0.83 ± 0.01, RK+GCE: 0.85 ± 0.03 vs 0.82 ± 0.03, Control: 0.82 ± 0.02 vs 0.84 ± 0.01 (p>0.05)) or during exercise (Baseline vs post intervention RER - RK: 0.89 ± 0.01 vs 0.87 ± 0.02, GCE: 0.90 ± 0.02 vs 0.90 ± 0.01, RK+GCE: 0.85 ± 0.01 vs 0.84 ± 0.01, Control: 0.86 ± 0.02 vs 0.87 ± 0.02 (p>0.05)). In conclusion, this study demonstrated that 8-weeks of supplementation with raspberry ketone, green coffee extract and a combination of these supplements had no effect on body mass, body composition or substrate utilisation.

description: El sector de biotecnología en Colombia tiene un gran potencial para el desarrollo económico del país, en este sentido la innovación representaría una oportunidad para esta industria Por lo que es importante explorar los desafíos del sector, desde una perspectiva humana y cultural, dado que es esta la que permite institucionalizar los valores y prácticas que giran alrededor de la innovación. En esta medida al revisar los diferentes modelos de cultura organizacional, se destaca el propuesto por Cameron y Quinn, el cual ha sido utilizado en varias investigaciones que relacionan la cultura organizacional y la innovación, concluyendo que aquellas empresas cuyas culturas organizacionales están ubicadas en los cuadrantes de clan y adhocrático son las más orientadas a la innovación. Para lo cual dentro de los instrumentos existentes, el coeficiente de la innovación de Rao y Weintraub (2013) brinda elementos para analizar la cultura organizacional en varios niveles como valores, comportamientos, clima, recursos, procesos y recompensas, permitiendo reconocer que aspectos específicos trabajar para potencializar la cultura organizacional de una empresa para poder orientarla a la innovación.

description: L'ensemble de ces notes ont été crée par John Baldwin lors d'une de ses premières périodes de résidence à Paris. Ces documents comprennent tous les magistri qu’il avait pu rencontrer dans ses sources. Aux XIIème et XIIIème siècles, les universités n'existant pas encore, le titre de magister s'il évoque certainement une compétence n'est pas rattaché de façon systématique au passage par les écoles. De surcroît, les magistris sont le plus souvent désignés par leur seul prénom. La lecture de ces données est donc difficile et suppose un long travail pour tenter d'identifier un individu auquel on pourrait rattacher plusieurs mentions. John Baldwin avait donc renoncé à utiliser ces données pour donner un prolongement à sa magnifique étude sur les gradués d'université et leur emploi par les Capétiens et les Plantagenêts. Néanmoins, il a conservé ces données et elles sont potentiellement très utile dans le cadre de Studium, comme le sont toutes les mentions dans les volumes des Fasti Ecclesiae Gallicanae de chanoines portant ce titre de magister sans autres précisions. L'ampleur des dépouillements rend ces données très utiles et nous devons une grande reconnaissance à John Baldwin pour avoir pris la peine de faire photocopier ses fiches et de nous les avoir transmises amicalement.
Les données ainsi que les images des fiches sont accessibles sur le site Internet à l'adresse suivante : http://studium-baldwin.lamop.fr/.
Les transcriptions des fiches ont été effectuées par des étudiants de Paris 1 Panthéon - Sorbonne mais elles n'ont pas été corrigées par la suite.

description: Crack closing forces are important to determine effective cyclic stress intensity factors ∆𝐾𝑒𝑓𝑓 in fatigue crack growth trials. By digital image correlation (DIC), the change of stiffness between the open and closed crack can be measured in different ways evaluating stress-strain curves either globally using integral strain perpendicular to crack growth direction or locally measured by virtual extensometers distributed along the crack. Crack opening and crack closing forces obtained by compliance of integral strain and of crack opening profiles measured by virtual extensometers are compared for a biaxial crack growth trial applying HCF and LCF cycles.

description: As quantum computing field is starting to reach the realm of advantage over classical algorithms, simulating quantum circuits becomes increasingly challenging as we design and evaluate more complex quantum algorithms. In this context, tensor networks, which have become a standard method for simulations in various areas of physics, from many-body quantum physics to quantum gravity, offer a natural approach. Despite the availability of efficient tools for physics simulations, simulating quantum circuits presents unique challenges, which I address in this work, specifically using the Quantum Approximate Optimization Algorithm as an example. The main results of this work span several steps of the problem. For the step of creating a tensor network, I demonstrate that applying the diagonal representation of quantum gates leads to a complexity reduction in tensor network contraction by one to four orders of magnitude. For large-scale contraction of tensor networks, I propose a step-dependent parallelization approach which performs slicing of partially contracted tensor network. Finally, I study tensor network contractions on GPU and propose an algorithm of contraction which uses both CPU and GPU to reduce GPU overhead. In our benchmarks, this algorithm reduces time to solution from 6 seconds to 1.5-2 seconds.

La discrimination et la stigmatisation des personnes francophones immigrantes et racisées dans leur recherche d'emploi à Ottawa : Les enjeux spécifiques du linguicisme
Creators: name: Deguerre, Wagner Junior
Publisher: name: My University

description: Ce mémoire s’intéresse au linguicisme, c’est-à-dire aux effets discriminants et stigmatisants de l’usage de la langue française et des accents chez des personnes immigrantes et racisées dans leur recherche d'emploi en contexte francophone minoritaire à Ottawa. À partir d’entretiens semi-dirigés, cette recherche révèle : le français comme source de discrimination en emploi en contexte anglophone majoritaire à Ottawa; les accents, les communications écrites et les expressions comme vecteurs de stigmatisation et de discrimination à l’intérieur même de la communauté francophone ; l’accent comme source de stigmatisation qui tantôt devient un marqueur de la race, tantôt dépasse la race pour renvoyer spécifiquement à la condition d’immigrant ; le dénigrement provenant de sa propre communauté ethnoraciale quand on adopte l’accent et les expressions du groupe dominant. Ce mémoire documente également les effets du linguicisme sur les personnes immigrantes et racisées : les sentiments d’humiliation ou d’injustice qui conduisent à l’insécurité linguistique, l’exclusion et l’auto-isolement en milieu de travail, l’adoption de l’accent dominant, et l’adoption de l’anglais comme langue d’usage. Enfin, les personnes victimes du linguicisme empruntent diverses stratégies afin d’y faire face ou de résister à ses effets, tels que l’humour, le renvoi de la question sur les origines et la revendication et affirmation de ses compétences professionnelles. Mots clés : Linguicisme, stigmatisation, discrimination, immigrant, racisation, francophonie minoritaire.
