description: The potential role that community-driven standards like IIIF can play beyond their basic functions is one of the significant aspects that I will address in my presentation (the International Image Interoperability Framework (IIIF) APIs as the backbone of scientific and participatory research). The talk will be an opportunity to discuss IIIF and to focus on the following two key points: Firstly, I will introduce the overarching architecture conceived in relation to the IIIF APIs within the "Participatory Knowledge Practices in Analogue and Digital Image Archives" (PIA) project. Secondly, I will discuss how the PIA data model will be impacted by the crowdsourcing and user-generated annotations that will be conducted on three photographic collections of the Swiss Society for Folklore Studies (SSFS/SGV).

description: Many complex systems are organized in the form of a network embedded in space. Important examples include the physical Internet infrastucture, road networks, flight connections, brain functional networks and social networks. The effect of space on network topology has recently come under the spotlight because of the emergence of pervasive technologies based on geo-localization, which constantly fill databases with people's movements and thus reveal their trajectories and spatial behaviour. Extracting patterns and regularities from the resulting massive amount of human mobility data requires the development of appropriate tools for uncovering information in spatially-embedded networks. In contrast with most works that tend to apply standard network metrics to any type of network, we argue in this paper for a careful treatment of the constraints imposed by space on network topology. In particular, we focus on the problem of community detection and propose a modularity function adapted to spatial networks. We show that it is possible to factor out the effect of space in order to reveal more clearly hidden structural similarities between the nodes. Methods are tested on a large mobile phone network and computer-generated benchmarks where the effect of space has been incorporated.

description: Mandibular fracture fixation and reconstruction are usually performed using titanium plates and screws, however, there is a need to improve current fixation techniques. Animal models represent an important step for the testing of new designs and materials. However, the validity of those preclinical models in terms of implant biomechanics remains largely unknown. In this study, we investigate the biomechanics of the sheep mandible as a preclinical model for testing the mechanical strength of fixation devices and the biomechanical environment induced on mandibular fractures. We aimed to assess the comparability of the biomechanical conditions in the sheep mandible as a preclinical model for human applications of fracture fixation devices and empower analyses of the effect of such defined mechanical conditions on bone healing outcome. We developed 3D finite element models of the human and sheep mandibles simulating physiological muscular loads and three different clenching tasks (intercuspal, incisal, and unilateral). Furthermore, we simulated fractures in the human mandibular body, sheep mandibular body, and sheep mandibular diastema fixated with clinically used titanium miniplates and screws. We compared, at the power stroke of mastication, the biomechanical environment (1) in the healthy mandibular body and (2) at the fracture sites, and (3) the mechanical solicitation of the implants as well as the mechanical conditions for bone healing in such cases. In the healthy mandibles, the sheep mandibular body showed lower mechanical strains compared to the human mandibular body. In the fractured mandibles, strains within a fracture gap in sheep were generally not comparable to humans, while similar or lower mechanical solicitation of the fixation devices was found between the human mandibular body fracture and the sheep mandibular diastema fracture scenarios. We, therefore, conclude that the mechanical environments of mandibular fractures in humans and sheep differ and our analyses suggest that the sheep mandibular bone should be carefully re-considered as a model system to study the effect of fixation devices on the healing outcome. In our analyses, the sheep mandibular diastema showed similar mechanical conditions for fracture fixation devices to those in humans.

description: A quantum control mechanism is proposed for molecular fragmentation processes within a scenario grounded on the quantum Zeno effect. In particular, we focus on the van der Waals Ne-Br$_2$ complex, which displays two competing dissociation channels via vibrational and electronic predissociation. Accordingly, realistic three dimensional wave packet simulations are carried out by using ab initio interaction potentials recently obtained to reproduce available experimental data. Two numerical models to simulate the repeated measurements are reported and analyzed. It is found that the otherwise fast vibrational predissociation is slowed down in favor of the slow electronic (double fragmentation) predissociation, which is enhanced by several orders of magnitude. Based on these theoretical predictions, some hints to experimentalists to confirm their validity are also proposed.

Operator-Schmidt decomposition and the geometrical edges of two-qubit gates

Year: 2010

description: Nonlocal two-qubit quantum gates are represented by canonical decomposition or equivalently by operator-Schmidt decomposition. The former decomposition results in geometrical representation such that all the two-qubit gates form tetrahedron within which perfect entanglers form a polyhedron. On the other hand, it is known from the later decomposition that Schmidt number of nonlocal gates can be either 2 or 4. In this work, some aspects of later decomposition are investigated. It is shown that two gates differing by local operations possess same set of Schmidt coefficients. Employing geometrical method, it is established that Schmidt number 2 corresponds to controlled unitary gates. Further, all the edges of tetrahedron and polyhedron are characterized using Schmidt strength, a measure of operator entanglement. It is found that one edge of the tetrahedron possesses the maximum Schmidt strength, implying that all the gates in the edge are maximally entangled.

Participatory Knowledge Practices in Analogue and Digital Image Archives
Swiss Society for Folklore Studies

description: As part of the Participatory Knowledge Practices in Analogue and Digital Image Archives (PIA) research project, we have been implementing Linked Open Usable Data (LOUD) standards including the International Image Interoperability Framework (IIIF) specifications to disseminate digital objects, their related metadata and streamline our processes. We have taken an incremental approach to IIIF deployment, first by installing the Simple Image Presentation Interface (SIPI), a IIIF Image API 3.0 server, followed by conceiving a workflow based on cookbook recipes created and vetted by the IIIF community for the generation of resources compatible with the IIIF Presentation API 3.0, one of the key components of our architecture. This workflow resulted in a monitoring exercise of this community-driven effort, principally to align the requirements of PIA and the IIIF Presentation API support of software clients. The presentation is available online at https://julsraemy.ch/prezi/euromed2022-pia-iiif.html.

Regulation of intestinal immune responses by the retinoic acid inducible transcription factor HIC1
Creators: name: Burrows, Kyle Aaron
Publisher: name: University of British Columbia
Year: 2017

description: The intestinal immune system must be able to respond to a wide variety of infectious organisms while maintaining tolerance to non-pathogenic microbes and food antigens. The Vitamin A metabolite all-trans-retinoic acid (atRA) has been implicated in the regulation of this balance, partially by regulating T cell and innate lymphoid cell (ILC) responses in the intestine. However, the molecular mechanisms of atRA-dependent intestinal immunity and homeostasis remain elusive. The work herein investigates the role for the POK/ZBTB family transcriptional repressor Hypermethylated in cancer 1 (HIC1, ZBTB29) in the regulation of immune cell responses in the intestine. Using genetically modified mice I demonstrate that Hic1 is specifically expressed in immune cells of the intestine at steady state in an atRA dependent manner. I further show that mice with a T cell-specific deletion of Hic1 have reduced numbers of T cells in the intestine. In addition, I demonstrate that HIC1-deficient T cells overproduce IL-17A in vitro and in vivo, and fail to induce intestinal inflammation in multiple murine models of inflammatory bowel disease, identifying a critical role for HIC1 in the regulation of T cell function in the intestinal microenvironment under both homeostatic and inflammatory conditions. In other studies, I investigated the cell-intrinsic role of HIC1 in intestinal ILC populations. I demonstrate that in the absence of HIC1, group 3 ILCs (ILC3s) are lost, resulting in increased susceptibility to infection with the murine bacterial pathogen Citrobacter rodentium. In addition, the loss of ILC3s leads to a local and systemic increase in IFN-γ-producing T cells that prevents the development of protective immunity against infection with the parasitic helminth Trichuris muris. Together the results presented here provide further insight into atRA mediated immune responses in the intestine as atRA-dependent expression of HIC1 in T cells and ILC3s regulate intestinal homeostasis, inflammation and protective immunity.

description: Participatory Knowledge Practices in Analogue and Digital Image Archives (PIA) is an interdisciplinary project based on three photographic collections (Atlas of Swiss Folklore, Family Kreis, Ernst Brunner) of the Swiss Society Folklore Studies (SSFS) which aims to "design a visual interface with machine learning-based tools to make it easy to annotate, contextualise, organise and link both images and their meta-information, to deliberately encourage the participatory use of archives". The human dimension is at the heart of the PIA project, allowing not only the enrichment and correction of metadata through crowdsourcing, but also enabling end users to generate their own collections - or stories - with new associated metadata as well as being able to upload personal content (call for images). Thus, a new data model will need to particularly take into account the following elements: Management of existing (non-controlled) keywords and the forthcoming folksonomy; Metadata correction and enrichment through crowdsourcing; Validation of metadata created by Machine Learning methods (notably Object Detection and Visual Text Co-Embedding); Annotation and transcription of digital surrogates and born-digital content that are compatible with the W3C Web Annotation Data Model; Linked Data reconciliation of entities (agent, concept, place) on the basis of the existing data model and the user-generated metadata; Content upload that could, to some extent, be compatible with the International Image Interoperability Framework (IIIF). PIA is as much about traditional crowdsourcing as it is about creating a modern Citizen Science platform that enables new uses and helps to streamline the research process of scholars. For this purpose, a user interface and various application programming interfaces (APIs) will be deployed to accommodate various forms of re-use by third parties. The presentation will give the current state of the data model, the different knowledge representations and the ways forward.

description: Most Sunyaev--Zel'dovich (SZ) and X-ray analyses of galaxy clusters try to constrain the cluster total mass and/or gas mass using parameterised models and assumptions of spherical symmetry and hydrostatic equilibrium. By numerically exploring the probability distributions of the cluster parameters given the simulated interferometric SZ data in the context of Bayesian methods, and assuming a beta-model for the electron number density we investigate the capability of this model and analysis to return the simulated cluster input quantities via three rameterisations. In parameterisation I we assume that the T is an input parameter. We find that parameterisation I can hardly constrain the cluster parameters. We then investigate parameterisations II and III in which fg(r200) replaces temperature as a main variable. In parameterisation II we relate M_T(r200) and T assuming hydrostatic equilibrium. We find that parameterisation II can constrain the cluster physical parameters but the temperature estimate is biased low. In parameterisation III, the virial theorem replaces the hydrostatic equilibrium assumption. We find that parameterisation III results in unbiased estimates of the cluster properties. We generate a second simulated cluster using a generalised NFW (GNFW) pressure profile and analyse it with an entropy based model to take into account the temperature gradient in our analysis and improve the cluster gas density distribution. This model also constrains the cluster physical parameters and the results show a radial decline in the gas temperature as expected. The mean cluster total mass estimates are also within 1 sigma from the simulated cluster true values. However, we find that for at least interferometric SZ analysis in practice at the present time, there is no differences in the AMI visibilities between the two models. This may of course change as the instruments improve.

description: Silicon-oxygen compounds are among the most important ones in the natural sciences, occurring as building blocks in minerals and being used in semiconductors and catalysis. Beyond the well known silicon dioxide, there are phases with different stoichiometric composition and nanostructured composites. One of the key challenges in understanding the Si-O system is therefore to accurately account for its nanoscale heterogeneity beyond the length scale of individual atoms. Here we show that a unified computational description of the full Si-O system is indeed possible, based on atomistic machine learning coupled to an active-learning workflow. We showcase applications to very-high-pressure silica, to surfaces and aerogels, and to the structure of amorphous silicon monoxide. In a wider context, our work illustrates how structural complexity in functional materials beyond the atomic and few-nanometre length scales can be captured with active machine learning.
Accretion onto Intermediate Mass Black Holes Regulated by Radiative Feedback I. Parametric Study for Spherically Symmetric Accretion

description: We study the effect of radiative feedback on accretion onto intermediate mass black holes (IMBHs) using the hydrodynamical code ZEUS-MP with a radiative transfer algorithm. In this paper, the first of a series, we assume accretion from a uniformly dense gas with zero angular momentum and extremely low metallicity. Our 1D and 2D simulations explore how X-ray and UV radiation emitted near the black hole regulates the gas supply from large scales. Both 1D and 2D simulations show similar accretion rate and period between peaks in accretion, meaning that the hydro-instabilities that develop in 2D simulations do not affect the mean flow properties. We present a suite of simulations exploring accretion across a large parameter space, including different radiative efficiencies and radiation spectra, black hole masses, density and temperature, $T_\infty$, of the neighboring gas. In agreement with previous studies we find regular oscillatory behavior of the accretion rate, with duty cycle $\sim 6%$, mean accretion rate 3% $(T_{\infty}/10^4 {\rm K})^{2.5}$ of the Bondi rate and peak accretion $\sim 10$ times the mean for $T_{\infty}$ ranging between 3000K and 15000K. We derive parametric formulas for the period between bursts, the mean accretion rate and the peak luminosity of the bursts and thus provide a formulation of how feedback regulated accretion operates. The temperature profile of the hot ionized gas is crucial in determining the accretion rate, while the period of the bursts is proportional to the mean size of the Strömgren sphere and we find qualitatively different modes of accretion in the high vs. low density regimes. We also find that softer spectrum of radiation produces higher mean accretion rate.

description: Nicht zuletzt im Zuge der Corona-Pandemie erleben die bereits zuvor in einem deutlichen Aufwärtstrend befindlichen Streaming-Dienste einen weiteren enormen Aufschwung. So lässt sich beim Konsum kultureller Güter sowohl im reinen Audio- als auch im audiovisuellen Bereich eine deutliche Verlagerung auf die „digitale Bühne“ beobachten. Doch partizipieren die Künstler auch adäquat an diesen Nutzungsformen? Armelle Grandjean geht in der vorliegenden Untersuchung der Frage nach, ob die angemessene Vergütung der ausübenden Künstler im digitalen Zeitalter noch sichergestellt ist oder ob diesbezüglich weiterer Reformbedarf besteht und wie dieser am besten gedeckt werden könnte. Das Interpretenrecht sieht mit der Regelung eines gesetzlichen Vergütungsanspruchs anstelle von Ausschließlichkeitsrechten bei der Zweitverwertung dabei ein besonderes Modell vor. Da sich Verbotsansprüche im Massengeschäft des Digitalzeitalters immer schwerer realisieren lassen, liegt die Annahme nahe, dass das Hauptanliegen der Kreativen, nämlich die Sicherstellung ihrer finanziellen Beteiligung an den Nutzungsvorgängen, durch gesetzliche Vergütungsansprüche besser gewährleistet werden kann. Dies betrifft die ausübenden Künstler auch in besonderem Maße, da ihre Rechte im Rahmen digitaler Geschäftsmodelle regelmäßig einem Verwerter übertragen worden sind. Das neue UrhDaG sieht insofern erstmals einen Direktvergütungsanspruch der Kreativen gegen Diensteanbieter vor, auch wenn sie ihre Rechte einem Dritten, also insbesondere Produzenten, eingeräumt haben. Die Autorin gibt einen umfassenden und strukturierten Überblick über die verschiedenen rechtlichen Instrumente zur Sicherstellung der angemessenen Vergütung ausübender Künstler im Musik- und Filmbereich im digitalen Zeitalter einschließlich Lösungen de lege ferenda unter besonderer Berücksichtigung der jüngsten unionsrechtlichen Entwicklungen sowie ihrer Umsetzung durch den nationalen Gesetzgeber.

description: We extend our recent phenomenological study of $pN \to NNππ$ reactions to the $\bar{p}N \to \bar{N}Nππ$ reactions for anti-proton beam momenta up to 3.0 GeV within an effective Lagrangian approach. The contribution of $N^*(1440)$ with its $Nσ$ decay mode is found to be dominant at the energies close to threshold for $\bar NNπ^+π^-$ and $\bar NNπ^0π^0$ channels. At higher energies or for $p\bar nπ^-π^-$ and $\bar NNπ^\pmπ^0$ channels where $N^*(1440)\to Nσ$ mode cannot contribute, large contributions from double-$Δ$, $Δ(1600) \to N^*(1440)π$, $Δ(1600) \to Δπ$ and $Δ(1620) \to Δπ$ are found. In the near-threshold region, sizeable contributions from $Δ\to Δπ$, $Δ\to Nπ$, $N \to Δπ$ and nucleon pole are also indicated. Although these results are similar to those for $pN\to NNππ$ reactions, the antinucleon-nucleon collisions are shown to be complementary to the nucleon-nucleon collisions and may even have advantages in some aspects. The PANDA/FAIR experiment is suggested to be an excellent place for studying the properties of relevant $N^*$ and $Δ^*$ resonances.

We show that the destructive effect of the phase noise is especially strong in the bistable regime. This explains why ground state cooling is still possible in the presence of phase noise, as it happens far away from the bistable regime. On the other hand, the optomechanical entanglement is strongly affected by phase noise.

description: Van der Waals (vdW) heterostructures composed of two-dimensional (2D) transition metal dichalcogenides (TMD) and vdW magnetic materials offer an intriguing platform to functionalize valley and excitonic properties in non-magnetic TMDs. Here, we report magneto-photoluminescence (PL) investigations of monolayer (ML) MoSe$_2$ on the layered A-type antiferromagnetic (AFM) semiconductor CrSBr under different magnetic field orientations. Our results reveal a clear influence of the CrSBr magnetic order on the optical properties of MoSe$_2$, such as an anomalous linear-polarization dependence, changes of the exciton/trion energies, a magnetic-field dependence of the PL intensities, and a valley $g$-factor with signatures of an asymmetric magnetic proximity interaction. Furthermore, first principles calculations suggest that MoSe$_2$/CrSBr forms a broken-gap (type-III) band alignment, facilitating charge transfer processes. The work establishes that antiferromagnetic-nonmagnetic interfaces can be used to control the valley and excitonic properties of TMDs, relevant for the development of opto-spintronics devices.

description: This photo shows my family home! How to make annotations of cultural heritage objects more accessible through IIIF The photo archive of the Swiss Society for Folklore Studies (SSFS) contains images on topics of everyday life, tradition and identity, forms of work and living, ranging in date from the late 19th century through the later part of the 20th century. Since the digitised photographic collections became available online in 2018, people knowledgeable about the archives' resources have come forward. Identifying people in historical photographs is important for preserving material culture but it is also a challenging endeavour. Users may still be able to identify archival material but sound ecosystems to facilitate online annotation of digital surrogates are lacking and thus users have to fall back on more traditional means of communication, such as email. Annotations with IIIF makes it easier to add context and commentary to cultural heritage objects in an interoperable manner. This ten-minute lightning session will cover how image annotations work with IIIF and how users can leverage it to identify people in historical image collections. Particular attention is paid to the artefactual nature of photography such as handwritten information, texture, colour as well as possible damages that can assist in the process of dating and identifying. How do we analyse or evaluate this kind of image information? What new interpretations emerge when users are able to annotate digital surrogates of photographs? We suggest an interdisciplinary perspective in the context of the Participatory Knowledge Practices in Analogue and Digital Image Archives (PIA) - https://about.participatory-archives.ch/ - that is useful for analysing the existing software and making annotations of historical photography accessible.

Terrain tracking motion planning and control of unmanned aerial vehicles

Publisher: name: University of British Columbia
Year: 2017

description: In a modern society, autonomous quadrotors can be used to perform tasks and collect data in dangerous and inaccessible environments where human involvement would traditionally be necessary. Unmanned Aerial Vehicles (UAVs), and especially the quadrotor, are still facing obstacles in terms of following a trajectory and flying autonomously in enclosed, complex or GPS denied areas. This work presents a novel framework for navigating a quadrotor over undulated terrains, so it can be of great importance for the use of UAVs in civilian applications such as monitoring of pipes, bridges and buildings. The proposed approach involves the use of a single-beam LiDAR to estimate the terrain profile under uncertainty. The LiDAR is installed at the base of a quadrotor and can be set at different angles to send information to the quadrotor about undulations of the terrain ahead. This strategy helps the quadrotor to build a smooth trajectory for the UAV and allows the controller to follow it closely. In turn, maneuverability of UAV over and around ground obstacles is improved in comparison to default autopilot controllers programmed to maintain a UAV at a given altitude. Through simulation, the result shows how this alternative technique with motion planning algorithms improves the performance of the quadrotor. In this thesis, the method used in the simulation was tested using a single-beam LiDAR reading the undulations of the terrain beneath and ahead of the quadrotor at a desired altitude. Then, motion planning algorithms, such as Gaussian filter and cubic spline, plan a smooth trajectory so that the quadrotor can avoid having to make any sudden turn or recoveries. Finally, this planned trajectory is provided to an appropriate controller, such as the model predictive control, linear quadratic regulator, proportional integral derivative control which help the quadrotor to not only follow the terrain exactly, but also to minimize energy wasted on sudden recoveries.

The Dirac operator is an element in the vector space $U_q(\g) \otimes \mathrm{cl}_q(\g)$ where the second tensor factor is a $q$-deformation of the classical Clifford algebra. The tensor space $ U_q(\g) \otimes \mathrm{cl}_q(\g)$ is given a structure of the adjoint module of the quantum group and the Dirac operator is invariant under this action. The purpose of this approach is to construct equivariant Fredholm modules and $K$-homology cycles. This work generalizes the operator introduced by Bibikov and Kulish in \cite{BK}.

description: We present a new formulation of the Einstein equations based on a conformal and traceless decomposition of the covariant form of the Z4 system. This formulation combines the advantages of a conformal decomposition, such as the one used in the BSSNOK formulation (i.e. well-tested hyperbolic gauges, no need for excision, robustness to imperfect boundary conditions) with the advantages of a constraint-damped formulation, such as the generalized harmonic one (i.e. exponential decay of constraint violations when these are produced). We validate the new set of equations through standard tests and by evolving binary black hole systems. Overall, the new conformal formulation leads to a better behavior of the constraint equations and a rapid suppression of the violations when they occur. The changes necessary to implement the new conformal formulation in standard BSSNOK codes are very small as are the additional computational costs.

description: Context. Gaia DR3 has offered the scientific community a remarkable dataset of approximately one million spectra acquired with the Radial Velocity Spectrometer (RVS) in the Calcium II triplet region, that is well-suited to identify very metal-poor (VMP) stars. However, over 40% of these spectra have no released parameters by Gaia's GSP Spec pipeline in the domain of VMP stars, whereas VMP stars are key tracers of early Galactic evolution. Aims. We aim to provide spectroscopic metallicities for VMP stars using Gaia RVS spectra, thereby producing a catalogue of bright VMP stars distributed over the full sky that can serve as the basis to study early chemical evolution throughout the Galaxy. Methods. We select VMP stars using photometric metallicities from the literature and analyse the Gaia RVS spectra to infer spectroscopic metallicities for these stars. Results. The inferred metallicities agree very well with literature high-resolution metallicities with a median systematic offset of 0.1 dex and standard deviation of $\sim$0.15 dex. The purity of this sample in the VMP regime is $\sim$80% with outliers representing a mere $\sim$3%. Conclusions. We make available an all-sky catalogue of $\sim$1500 stars with reliable spectroscopic metallicities down to [Fe/H]$\sim$-4.0, of which $\sim$1000 are VMP stars. More than 75% of these stars have either no metallicity value in the literature to date or are flagged to be unreliable in their literature metallicity estimates. This catalogue of bright (G<13) VMP stars is three times larger than the current sample of well-studied VMP stars in the literature in this magnitude range, making it ideal for high-resolution spectroscopic follow-up and to study the properties of VMP stars in different parts of our Galaxy.

description: A Holevo measure is used to discuss how much information about a given POVM on system $a$ is present in another system $b$, and how this influences the presence or absence of information about a different POVM on $a$ in a third system $c$. The main goal is to extend information theorems for mutually unbiased bases or general bases to arbitrary POVMs, and especially to generalize "all-or-nothing" theorems about information located in tripartite systems to the case of \emph{partial information}, in the form of quantitative inequalities. Some of the inequalities can be viewed as entropic uncertainty relations that apply in the presence of quantum side information, as in recent work by Berta et al. [Nature Physics 6, 659 (2010)]. All of the results also apply to quantum channels: e.g., if $\EC$ accurately transmits certain POVMs, the complementary channel $\FC$ will necessarily be noisy for certain other POVMs. While the inequalities are valid for mixed states of tripartite systems, restricting to pure states leads to the basis-invariance of the difference between the information about $a$ contained in $b$ and $c$.
description: 21 pages. An earlier version of this paper attempted to prove our main uncertainty relation, Theorem 5, using the achievability of the Holevo quantity in a coding task, an approach that ultimately failed because it did not account for locking of classical correlations, e.g. see [DiVincenzo et al. PRL. 92, 067902 (2004)]. In the latest version, we use a very different approach to prove Theorem 5
title: An investigation of teacher professional development through the pedagogical cells of secondary school teachers of English in Senegal

description: In educational research, a large number of studies on teacher professional development (TPD) have been conducted in various parts of the world and a range of insights gained on this area of research. Most ideas about effective TPD contend that it needs to be context-sensitive, promote learning through reflection, favour collaboration within communities of teachers, aim at improving students’ learning. However, although the role of teachers in education has been widely considered as determinant to successful student learning, there is still little documented knowledge related to TPD in many parts of the world, especially in Sub-Saharan Africa where it is argued to be acutely needed. Taking a sociocultural approach to teacher learning by understanding it through a situated perspective, this study investigates how TPD is conceptualised in Senegal and implemented through the pedagogical cells (PC) of secondary school teachers of English. It also explores these teachers’ lived experiences of TPD within their PCs and their schools as working environments. Using a vertical case study approach, participants were selected from the three different levels of the organisation of TPD in Senegal: four senior English Language Teaching (ELT) officials at the national level, one teacher trainer and three departmental pedagogical cell (DPC) coordinators at the regional level, and 14 teachers from two schools and their leaders at the local level. Data was collected through semi-structured interviews, observations, and documents inspection. The analysis of the data is informed by a thematic approach. The findings show that most of the conceptualisations of TPD expressed by the participants of this study are in line with current understandings of effective TPD in educational research, although they are informed by different approaches and views of learning. The findings also indicate that the studied teachers’ DPCs and PCs resemble learning communities in some ways and that the school cultures may impact on teachers’ professional learning. However, the main dissonance in understandings of TPD between the national level and the other two appears to be the scarcity of collective reflection within the activities of the studied DPCs and PCs. This thesis argues for a shift on understanding of teacher professionalism within Senegalese educational context. In this sense, it proposes a cyclical collective reflection within teachers’ PCs based on classroom practice and the use of peer observation within these small groups of teachers. Nonetheless, this thesis also advocates for a combination of top-down and bottom-up approaches to TPD in this country where learner-centred approaches to teaching are being promoted.

description: Electron-hole generation and recombination rates for plasmon emission and absorption in Graphene are presented. The recombination times of carriers due to plasmon emission have been found to be in the tens of femtoseconds to hundreds of picoseconds range. The recombination times depend sensitively on the carrier energy, carrier density, temperature, and the plasmon dispersion. Carriers near the Dirac point are found to have much longer lifetimes compared to carriers at higher energies. Plasmons in a Graphene layer on a polar substrate hybridize with the surface optical phonons and this hybridization modifies the plasmon dispersion. We also present generation and recombination rates of carriers due to plasmon emission and absorption in Graphene layers on polar substrates.

description: We present exact solutions of string cosmological models characterized by five dimensional metrics (with four-dimensional real Lie groups as isometry groups), space independent dilaton and vanishing torsion. As an example we consider VII 0 \oplus R model and show that it is equivalent to the (4 +1)-dimensional cosmological model coupled to perfect fluid with negative deceleration parameters (accelerating universe).

description: Excluded-volume effects can play an important role in determining transport properties in diffusion of particles. Here, the diffusion of finite-sized hard-core interacting particles in two or three dimensions is considered systematically using the method of matched asymptotic expansions. The result is a nonlinear diffusion equation for the one-particle distribution function, with excluded-volume effects enhancing the overall collective diffusion rate. An expression for the effective (collective) diffusion coefficient is obtained. Stochastic simulations of the full particle system are shown to compare well with the solution of this equation for two examples.
