description: We present some recent studies on the physical conditions and the chemistry of the interstellar medium (ISM) in the Galactic center region (GCR). Large scale shocks in the context of a bar potential can play a role in explaining the observed properties, at least in some particular regions. Alternatively, we propose that the observed properties (inhomogeneity, high temperatures of the molecular gas, rich chemistry,...) of the GCR ISM can be the consequence of the recent past ($10^6-10^7$ years ago) of massive star formation in the GCR.

description: Speaker diarisation systems nowadays use embeddings generated from speech segments in a bottleneck layer, which are needed to be discriminative for unseen speakers. It is well-known that large-margin training can improve the generalisation ability to unseen data, and its use in such open-set problems has been widespread. Therefore, this paper introduces a general approach to the large-margin softmax loss without any approximations to improve the quality of speaker embeddings for diarisation. Furthermore, a novel and simple way to stabilise training, when large-margin softmax is used, is proposed. Finally, to combat the effect of overlapping speech, different training margins are used to reduce the negative effect overlapping speech has on creating discriminative embeddings. Experiments on the AMI meeting corpus show that the use of large-margin softmax significantly improves the speaker error rate (SER). By using all hyper parameters of the loss in a unified way, further improvements were achieved which reached a relative SER reduction of 24.6% over the baseline. However, by training overlapping and single speaker speech samples with different margins, the best result was achieved, giving overall a 29.5% SER reduction relative to the baseline.

description: Protein phosphorylation represents one of the most important post-translational modifica- tions (PTMs) for cell signalling, and is is catalysed by a group of enzymes called protein kinases. Through this activity they serve as key regulators of almost all cellular processes. This is achieved at any time by a network of different kinases that are transiently active. The fidelity of cell systems control therefore requires that each kinase targets only a restricted set of substrates. This specificity is achieved partly by contextual factors that separate kinases spatially and temporally, but also by sequence features that are encoded in the kinase domain itself. For this thesis I focus on elements of kinase specificity that are encoded in the the active site of the enzyme. During these investigations I have tried to address three main questions: 1) How is specificity for residues surrounding the phosphorylation site determined in the kinase? 2) How did these specificities evolve? and 3) To what extent does kinase evolution correlate with the evolution of its substrates? First, I developed a sequence-based method for the automated detection of kinase speci- ficity determining residues (SDRs). The putative determinants were then rationalised using available structural data, and in two specific cases were validated experimentally. I also used mutation data from The Cancer Genome Atlas (TCGA) to demonstrate that kinase SDRs are often targeted during cancer. Second, a global analysis of SDR evolution was performed for kinases following gene duplication and speciation, revealing that SDRs often diverge between paralogues but not between orthologues. This global analysis is followed by a detailed case study of G-protein coupled receptor kinase (GRKs) evolution using ancestral sequence reconstructions. Third, I inferred global substrate preferences in a taxonomically broad range of species using phosphoproteome data. I then related the evolution of substrate motif sequences to that of their cognate effector kinases where possible. The results strongly suggest that many of the motifs emerged in a universal eukaryotic ancestor. I finish by summarising the major findings of this doctoral research, which to my knowl- edge represents the most comprehensive analysis to date of protein kinase specificity and its evolution.

description: This dissertation examines the bread subsidy in the Hashemite Kingdom of Jordan. It scrutinizes the socio-political conflicts that surround this policy, the spatial practices that subsume it and the ways in which it is understood and given meaning. Despite repeated attempts by international financial institutions to eliminate them, authoritarian regimes throughout the region have gone to great lengths to maintain this and similar welfare programs, even extending them during the tumult of the so-called ‘Arab Spring.’ This dissertation seeks to answer why. Through the lens of bread, I suggest a new approach to understanding state power, not as the straightforward product of a monolithic entity but as the unstable product of social practices that make the state appear to exist. Building on the work of Judith Butler and Alex Jeffrey, I call these routine actions “performing the state.” The empirical chapters, based on extensive fieldwork in Jordan, attend to how welfare provision not only reflects the state—its capacities, historical development or cultural proclivities—but performs it into being. The analysis centers on how certain institutions and actors, through their imbrication in the social, spatial and political patterns of welfare provision, work to entrench the state—as an idea, a material force and a locus of affective investment—in the lives of citizens. In attending to how the Jordanian state is constituted and reproduced through discourses, spatial practices of reach, moral economies and political rationalities, this study seeks to illuminate the iterative processes of reference that create the appearance of an autonomous structure that both citizens and scholars call the state. By understanding the state as the contingent product of routine performances, we can better examine the disproportionate importance of particular welfare programs to assembling state power and fostering authoritarian outcomes, as well as their links to key political processes and policy outcomes.

description: Paranoia and conspiracy thinking are known to be distinct but correlated constructs, but it is unknown whether certain types of conspiracy thinking are more common in paranoia than others. In a large (n = 1000), pre-registered online study we tested if endorsement of items on a new Components of Conspiracy Ideation Questionnaire varied according to whether harm was described as being (a) intentional and (b) self-referential. Our predictions were supported: paranoia was positively associated with endorsement of items on this questionnaire overall and more paranoid individuals were more likely to endorse items describing intentional and self-referential harm. Belief in any item on the Components of Conspiracy Ideation Questionnaire was associated with belief in others and items describing incidental harm and harm to others were found to be more believable overall. Individuals who endorsed conspiracy theory items on the questionnaire were more likely to state that people similar to them would as well, although this effect was not reduced in paranoia, counter to our expectations.

description: Time-delay cosmography of lensed quasars has achieved 2.4% precision on the measurement of the Hubble constant, $H_0$. As part of an ongoing effort to uncover and control systematic uncertainties, we investigate three potential sources: 1- stellar kinematics, 2- line-of-sight effects, and 3- the deflector mass model. To meet this goal in a quantitative way, we reproduced the H0LiCOW/SHARP/STRIDES (hereafter TDCOSMO) procedures on a set of real and simulated data, and we find the following. First, stellar kinematics cannot be a dominant source of error or bias since we find that a systematic change of 10% of measured velocity dispersion leads to only a 0.7% shift on $H_0$ from the seven lenses analyzed by TDCOSMO. Second, we find no bias to arise from incorrect estimation of the line-of-sight effects. Third, we show that elliptical composite (stars + dark matter halo), power-law, and cored power-law mass profiles have the flexibility to yield a broad range in $H_0$ values. However, the TDCOSMO procedures that model the data with both composite and power-law mass profiles are informative. If the models agree, as we observe in real systems owing to the "bulge-halo" conspiracy, $H_0$ is recovered precisely and accurately by both models. If the two models disagree, as in the case of some pathological models illustrated here, the TDCOSMO procedure either discriminates between them through the goodness of fit, or it accounts for the discrepancy in the final error bars provided by the analysis. This conclusion is consistent with a reanalysis of six of the TDCOSMO (real) lenses: the composite model yields $74.0^{+1.7}_{-1.8}$ $km.s^{-1}.Mpc^{-1}$, while the power-law model yields $H_0=74.2^{+1.6}_{-1.6}$ $km.s^{-1}.Mpc^{-1}$. In conclusion, we find no evidence of bias or errors larger than the current statistical uncertainties reported by TDCOSMO.

Colonialism and the Dialectics of Islamic Reform in a Malay State: Pengasoh and the Making of a Muslim Public Sphere in Kelantan, 1915 - 1925

description: Thesis Abstract This dissertation focuses on an important Muslim periodical "Pengasoh" and the role it has played in the Muslim ‘reform’ discourses in early 20th century Malaya. The periodical was first published by the Majlis Agama Islam Kelantan (Kelantan’s State Islamic Council) in 1918. Within the context of Malay-Muslim society, Kelantan was, and in some ways remain, a particularly important centre for Islamic culture and learning, attracting teachers and students from across the region. The Majlis itself was established by some of the leading ulama on the Peninsula at the time. Many were educated in the Middle East and had close associations with some of the major Muslim reformists in Egypt and the Haramayn. The standing of the Kelantanese 'ulama' within Malay-Muslim Southeast Asia, and the role of "Pengasoh" within that community meant that the periodical gives a unique glimpse into the world of these intellectual-theocrats. In this sense, the study of “Pengasoh” is a prism which could further our understanding of the dynamics of Islamic intellectual culture in Kelantan – as well as the surrounding region – during the early decades of the 20th century. What this dissertation attempts to show is how the ideational aspects of this community may be better understood if two important factors are taken into account - the linkages throughout the Indian Ocean littoral which form the cultural and religious milieu which shaped the thinking within the Kelantanese ‘ulama’; and how this sits in a wider conversation between "Islam" and "modernity". This moves away from existing studies which sought to clearly demarcate these Islamicate discourses as one between ‘Modernist’ Muslims and their ‘traditionalist’ counterparts.
On the metal abundance in the core of M87

description: We revisit the XMM-Newton observation of M87 to make a new and more detailed measurement of the metal abundance profile. After having verified that spectral fits with single temperature models show a dramatic abundance drop within 1 arcmin of the cluster core, we show that more appropriate models, which include a multi-temperature component to account for the strong temperature gradient observed in M87, and a power-law component to account for the emission of the nucleus and knot A, give a substantially flat abundance profile. The drastic abundance decrement found by fitting a single temperature component to the data is an artifact known as "Fe-bias" (Buote 2000a,b) following from the application of an oversimplified spectral model to the data.

description: We observed the Galactic black hole candidate XTE J1650-500 early in its Fall, 2001 outburst with the XMM-Newton European Photon Imaging pn Camera (EPIC-pn). The observed spectrum is consistent with the source having been in the "very high" state. We find a broad, skewed Fe K-alpha emission line which suggests that the primary in this system may be a Kerr black hole, and which indicates a steep emissivity profile that is hard to explain in terms of a standard accretion disk model. These results are quantitatively and qualitatively similar to those from an XMM-Newton observation of the Seyfert galaxy MCG--6-30-15. The steep emissivity in MCG--6-30-15 may be explained by the extraction and dissipation of rotational energy from a black hole with nearly- maximal angular momentum or material in the plunging region via magnetic connections to the inner accretion disk. If this process is at work in both sources, an exotic but fundamental general relativistic prediction may be confirmed across a factor of 10^6 in black hole mass. We discuss these results in terms of the accretion flow geometry in stellar-mass black holes, and the variety of enigmatic phenomena often observed in the very high state.

description: The origin of the extended soft X-ray emission around nearby highly inclined disk galaxies (often called as X-ray corona) remains uncertain. The emission could arise from volume-filling hot gas and/or its interaction with cool gas. Morphological properties of the X-ray emission can provide additional information to distinguish these different origins. We define model-independent parameters H50, H75, and H95 - vertical scales that enclose 50%, 75%, and 95% of the total flux of the emission, respectively. We study the correlation of these parameters with galaxy properties inferred from infrared observations of a sample of nearby highly inclined disk galaxies with high-quality Chandra data. We find weak negative correlations between H50or H75and the surface star formation rate (ISFR) and no correlation for H95. However, we detect strong, negative correlations of the vertical concentration of the emission, defined as H50/H95 or H75/H95, with ISFR. Our findings suggest that the X-ray emission around disk galaxies is likely comprised of two components: the extended, weak emission, characterized by H95, is influenced by the outflowing hot gas entrained in star formation driven winds, whereas the strong emission close to the disk which is often rich in cool gas characterized by H50 or H75, is largely impacted by cool-hot gas interaction.

description: Effects of rotational mode coupling on photometric parameters of stellar oscillations are studied. At moderate rotation rates, a strong coupling between modes of spherical harmonic degree, $\ell$, differing by 2 and of the same azimuthal order, $m$, takes place if the frequencies are close. This is a common situation amongst main sequence pulsators. Numerical results for a sequence of $β$ Cephei star models are reported for the two- and three-mode couplings. One consequence of mode coupling is that modes of higher degree should be considered in photometric mode identification. Modes with nominal degree $\ell>2$ acquire substantial $\ell\le2$ components and therefore are more likely to reach detectable amplitudes. Coupled mode positions in the amplitude ratio - phase difference diagrams, based on multicolour photometry, become both aspect- and $m$-dependent. Examples of the mode path in the diagram with varying aspect are given. The diagrams remain a useful tool for mode identification in rotating stars but the tool must be used with care.

description: Atrial fibrillation (AF) is the most common cardiac arrhytmia, characterised by the chaotic motion of electrical wavefronts in the atria. In clinical practice, AF is classified under two primary categories: paroxysmal AF, short intermittent episodes separated by periods of normal electrical activity, and persistent AF, longer uninterrupted episodes of chaotic electrical activity. However, the precise reasons why AF in a given patient is paroxysmal or persistent is poorly understood. Recently, we have introduced the percolation based Christensen-Manani-Peters (CMP) model of AF which naturally exhibits both paroxysmal and persistent AF, but precisely how these differences emerge in the model is unclear. In this paper, we dissect the CMP model to identify the cause of these different AF classifications. Starting from a mean-field model where we describe AF as a simple birth-death process, we add layers of complexity to the model and show that persistent AF arises from re-entrant circuits which exhibit an asymmetry in their probability of activation relative to deactivation. As a result, different simulations generated at identical model parameters can exhibit fibrillatory episodes spanning several orders of magnitude from a few seconds to months. These findings demonstrate that diverse, complex fibrillatory dynamics can emerge from very simple dynamics in models of AF.

description: A strategy for finding transition paths connecting two stable basins is presented. The starting point is the Hamilton principle of stationary action; we show how it can be transformed into a minimum principle through the addition of suitable constraints like energy conservation. Methods for improving the quality of the paths are presented: for example, the Maupertuis principle can be used for determining the transition time of the trajectory and for coming closer to the desired dynamic path. A saddle point algorithm (conjugate residual method) is shown to be efficient for reaching a ``true'' solution of the original variational problem.

 Diagnosis: Because only three females are available, it is not possible at this time to diagnosis this species from others in the genus.
 Description: Male Adult: Unknown. Female Adult (pinned): Length. Body, 2.0 mm; forewing, 4.0 mm. Body dark brown to black. Legs brown becoming pale brown distally. Forewing (Fig. 25E): reddish-brown; vein CuP not strongly curved towards A; vein ICu 2 free ; ICu 1 attached basally to CuA by crossvein; MP 2 united basally to IMP by cross veins. Legs: yellowish to pale reddish-brown to grey, with basal blackish shading. Hind wing absent. Abdomen. Dark brown with black markings. Larva: Unknown.
 Distribution: Known only from the type locality in Zapote, Guatemala.

 Discussion: Little is known concerning this species, which was described from Guatemala on the basis of three dried female adults. The type locality, Zapote, is located in the state of Escuintla, 12 km. northwest of the town of Escuintla (N14°23’; W90°52’). The original description was very vague, and consisted of only three sentences. It is highly questionable if a male or larva can ever be associated with this species. As is the situation with Leptohyphes berneri, there is a strong possibility that a previously described species of Leptohyphes known only from the larval stage may be synonymous with this species.
 During a collecting trip to Guatemala in 2007, the type locality of this species (the Río Zapote, near the town of Zapote) was located by DEB with the assistance of a Guatemalan entomologist. The Río Zapote is about 8 meters wide, swiftly flowing, with rock/rubble substrate, ranges in depth from a few centimeters to over a meter, and flows through numerous coffee plantations. Numerous Leptohyphes larvae were collected from the type locality, representing at least three species of Leptohyphes. Until rearing studies can be conducted and the larva associated with the adult, the status of this species will be very uncertain.
 Primary Type material examined: Leptohyphes brevissimus, 1 female adult (pinned), designated as a type specimen; 3 associated slides (1 with FW, 1 with 3 legs, 1 with last 4 abdominal segments/female genitalia). GUATEMALA: Zapote, G.C. Champion [BMNH].

description: Conventional or “primed” human embryonic stem cells (hESCs) rely on FGF and TGFβ signalling for self-renewal, and occupy a developmentally advanced state of pluripotency comparable to mouse EpiSCs. Recent reports demonstrate that a naïve state of human pluripotency can be consistently derived either through transient histone deacetylase inhibition mediated resetting of conventional hESCs or via isolation of the inner cell mass. Long-term propagation of this state can be achieved using a cocktail of MEK, GSK3 and PKC inhibition in conjunction with leukaemia inhibitory factor (LIF) supplementation (t2iLGö) and a feeder layer of inactivated mouse embryonic fibroblasts. However, the way in which this signalling environment is interpreted in order to maintain naïve pluripotency remains unclear. I demonstrate a substrate consisting of a high concentration of tissue-derived laminin in combination with t2iLGö is sufficient to replace the feeder layer. Cultures maintained under these conditions are karyotypically normal, maintain a naive pluripotent transcriptional profile and exhibit reduced aberrant expression of mesodermal and endodermal lineage markers. I utilise the increased stringency of this culture system in combination with small molecule inhibitors to examine the roles of FGF, Activin/Nodal and JAK/STAT signalling in human naïve pluripotency. Naïve hESCs proliferate and maintain pluripotency marker expression in the presence of FGF receptor inhibition. In contrast, TGFβ signalling inhibition leads to rapid downregulation of human specific naïve pluripotency marker, KLF17, followed by the eventual collapse of the naïve transcription factor circuitry. Naïve hESCs self-renew in both the absence of LIF and presence of JAK/STAT inhibitors. However, further investigation of JAK/STAT signalling identified the increased potency of Interleukin 6 (IL-6) over LIF to activate the JAK/STAT pathway. Supplemental IL-6 improves colony-forming capacity under self-renewing conditions and attenuates differentiation following inhibitor withdrawal. Furthermore, prolonged activation of IL-6 signalling suppresses expression of GATA2 and GATA3 and upregulates KLF4 transcripts. Finally, I investigate whether ablation of PKCι is sufficient to replace the activity of the PKC inhibitor, Gö6983. Established naïve cultures that are PKCι null continue to express naïve markers and suppress upregulation of lineage makers following withdrawal of Gö6983. Furthermore, ablation of PKCι in conventional ESCs enables the maintenance of NANOG expression and the emergence of KLF17 expression in the absence of Gö6983 during histone deactylase mediated resetting.
Degeneracies and scaling relations in general power-law models for gravitational lenses

description: The time delay in gravitational lenses can be used to derive the Hubble constant in a relatively simple way. The results of this method are less dependent on astrophysical assumptions than in many other methods. The most important uncertainty is related to the mass model used. We discuss a family of models with a separable radial power-law and an arbitrary angular dependence for the potential psi = r^beta * F(theta). Isothermal potentials are a special case of these models with beta=1. An additional external shear is used to take into account perturbations from other galaxies. Using a simple linear formalism for quadruple lenses, we can derive H0 as a function of the observables and the shear. If the latter is fixed, the result depends on the assumed power-law exponent according to H0 proportional to (2-beta)/beta. The effect of external shear is quantified by introducing a `critical shear' gamma_c as a measure for the amount of shear that changes the result significantly. The analysis shows, that in the general case H0 and gamma_c do not depend on the position of the lens galaxy. We discuss these results and compare with numerical models for a number of real lens systems.

description: We present the evaluation of two different design configurations of a two-stage PrNi$_5$ continuous nuclear demagnetization refrigerator. Serial and parallel configurations of the two stages are considered, with emphasis on the attainable cooling power at sub-mK temperatures and the impact of the design choices on the operation of the refrigerator. Numerical simulations of heat transfer in the setup are used to evaluate the performance of the refrigerator as well as the technological requirements for the essential thermal links. In accord with similar findings for adiabatic demagnetization refrigerators [Shirron, \emph{Cryogenics} \textbf{62}, 2014], our simulations show that the performance of both configurations improves as the thermal links improve, and that the parallel configuration yields a higher cooling power than the series design for a given thermal link resistance and sample temperature.

description: Massive Dirac fermions break the chiral symmetry explicitly and also make the Berry curvature of the band structure non-Abelian. By utilizing the Green's function technique, we develop a microscopic theory to establish a set of quantum diffusive equations for massive Dirac materials in the presence of electric and magnetic fields. It is found that the longitudinal magnetoresistance is always negative and quadratic in the magnetic field, and decays quickly with the mass. The theory is applicable to the systems with non-Abelian Berry curvature and resolves the puzzles of anomalous magnetotransport properties measured in topological materials.

Quenched Results for Light Quark Physics with Overlap Fermions

description: We present results of a quenched QCD simulation with overlap fermions on a lattice of volume V = 16^3X32 at beta=6.0, which corresponds approximatively to a lattice cutoff of 2 GeV and an extension of 1.4 fm. From the two-point correlation functions of bilinear operators we extract the pseudoscalar meson masses and the corresponding decay constants. From the GMOR relation we determine the chiral condensate and, by using the K-meson mass as experimental input, we compute the sum of the strange and average up-down quark masses (m_s + \hat m). The needed logarithmic divergent renormalization constant Z_S is computed with the RI/MOM non-perturbative renormalization technique. Since the overlap preserves chiral symmetry at finite cutoff and volume, no divergent quark mass and chiral condensate additive renormalizations are required and the results are O(a) improved.

Transverse momentum and process dependent azimuthal anisotropies in $\sqrt{s_{\mathrm{NN}}}=8.16$ TeV $p$+Pb collisions with the ATLAS detector

description: The azimuthal anisotropy of charged particles produced in $\sqrt{s_{\mathrm{NN}}}=8.16$ TeV $p$+Pb collisions is measured with the ATLAS detector at the LHC. The data correspond to an integrated luminosity of $165$ $\mathrm{nb}^{-1}$ that was collected in 2016. Azimuthal anisotropy coefficients, elliptic $v_2$ and triangular $v_3$, extracted using two-particle correlations with a non-flow template fit procedure, are presented as a function of particle transverse momentum ($p_\mathrm{T}$) between $0.5$ and $50$ GeV. The $v_2$ results are also reported as a function of centrality in three different particle $p_\mathrm{T}$ intervals. The results are reported from minimum-bias events and jet-triggered events, where two jet $p_\mathrm{T}$ thresholds are used. The anisotropies for particles with $p_\mathrm{T}$ less than about $2$ GeV are consistent with hydrodynamic flow expectations, while the significant non-zero anisotropies for $p_\mathrm{T}$ in the range $9$-$50$ GeV are not explained within current theoretical frameworks. In the $p_\mathrm{T}$ range $2$-$9$ GeV, the anisotropies are larger in minimum-bias than in jet-triggered events. Possible origins of these effects, such as the changing admixture of particles from hard scattering and the underlying event, are discussed.

Towards a new global QCD analysis: low x DIS data from non-linear evolution

description: A new approach to global QCD analysis is developed. The main ingredients are two QCD-based evolution equations. The first one is the Balitsky-Kovchegov nonlinear equation, which sums higher twists while preserving unitarity. The second equation is linear and it is responsible for the correct short distance behavior of the theory, namely it includes the DGLAP kernel. Our approach allows extrapolation of the parton distributions to very high energies available at the LHC as well as very low photon virtualities, $Q^2\ll 1 {\rm GeV^2}$. All existing low $x$ data on the $F_2$ structure function is reproduced using one fitting parameter. The resulting $χ^2/df=1$. Analyzing the parameter $λ\equiv \partial\ln F_2/\partial(\ln 1/x)$ at very low $x$ and $Q^2$ well below $1 {\rm GeV^2}$ we find $λ\simeq 0.08 - 0.1$. A result which agrees with the "soft pomeron" intercept without involving soft physics.

description: Ce mémoire traite du thème des médiations mises en place lors d’une leçon en économie et droit au secondaire II. Des champs épistémologiques différents, tels que les concepts de médiation (Vygotski, 1934/1985) et des types de discours (Scott & Amettler, 2007) ont été mobilisés afin d’analyser les échanges entre un stagiaire et ses élèves. Deux enregistrements de leçons ont été effectués à quatre mois d’intervalle capturant ainsi tous les échanges entre enseignant-stagiaire et élèves. Les phases avant, pendant et après la leçon ont été décortiquées afin de comprendre pourquoi un enseignant choisirait un type de discours plutôt qu’un autre, et quel impact cela aurait sur les élèves. Nous avons déterminé que l’expérience de l’enseignant-stagiaire semble jouer un rôle dans le choix d’un type de discours. Le fait que l’enseignant soit moins expérimenté l’oriente plus spontanément vers un discours d’autorité, plus rassurant pour le novice. Le fait de n’avoir pas effectué de planification détaillée de leçon en amont semble également jouer un rôle dans le type de discours mobilisé. Enfin, un discours peu interactif et peu ou pas dialogique semble désengager les élèves et générer de faibles interventions de leur part. Alors qu’un discours plus interactif et éventuellement dialogique semble favoriser une plus grande implication des élèves. Un discours plus ouvert semble également éviter des erreurs et/ou malentendus. Les conclusions du présent mémoire fournissent des pistes pour améliorer les types de médiations à mobiliser dans les pratiques enseignantes.
