description: The West Eurasian steppes during the Eneolithic, the Early and Middle Bronze and the Iron Age were largely inhabited by communities believed to show an elevated level of spatial mobility, often linked to their subsistence economy. In this doctoral thesis, questions concerning the mobility and migration as well as the diet and economy of these, in some sense mobile communities were approached by applying isotope analyses, particularly 87Sr/86Sr, δ18O, δ15N and δ13C analyses. Adapting these methods to a study area of extremely large spatial and chronological dimensions and to a proportionally undersized sample set certainly tested the limits of the methods, but it also allowed a wide variety of questions to be answered.

description: A role of reducible connections in Non-Abelian Seiberg-Witten invariants is analyzed with massless Topological QCD where monopole is extended to non-Abelian groups version. By giving small external fields, we found that vacuum expectation value can be separated into a part from Donaldson theory, a part from Abelian Monopole theory and a part from non-Abelian monopole theory. As a by-product, we find identities of U(1) topological invariants. In our proof, the duality relation and Higgs mechanism are not necessary.

description: System identification has been a major advancement in the evolution of engineering. As it is by default the first step towards a significant set of adaptive control techniques, it is imperative for engineers to apply it in order to practice control. Given that system identification could be useful in creating a digital twin, this work focuses on the initial stage of the procedure by discussing simplistic system order identification. Through specific numerical examples, this study constitutes an investigation on the most \natural" method for estimating the order from responses in a convenient and seamless way in time-domain. The method itself, originally proposed by Ho and Kalman and utilizing linear algebra, is an intuitive tool retrieving information out of the data themselves. Finally, with the help of the limitations of the methods, the potential future outlook is discussed, under the prism of forming a digital twin.

 Taxonomic description: Cf. Bell, 1887b: 534, pl. XLV, fig. 6.
 Examination of the gross morphology and the ossicle assemblage leaves no doubt that this name should be put in the synonymy of H. scabra. The type locality (Angola, West Africa) is, however, very problematic as this implies that H. scabra is also present in the Atlantic Ocean. We can only conclude that this is an error of Bell.
 Remarks: Bell (1887b) stated that no tables were to be found; our (re-)examination, however, did reveal tables, in size and shape identical to those of H. scabra.

description: We study how statistical properties of supermassive black holes depend on the frequency and conditions for massive seed formation in cosmological simulations of structure formation. We develop a novel method to recalculate detailed growth histories and merger trees of black holes within the framework of the Illustris simulation for several seed formation models, including a physically motivated model where black hole seeds only form in progenitor galaxies that conform to the conditions for direct collapse black hole formation. While all seed models considered here are in a broad agreement with present observational constraints on black hole populations from optical, UV and X-ray studies, we find that they lead to widely different black hole number densities and halo occupation fractions which are currently observationally unconstrained. In terms of future electromagnetic spectrum observations, the faint-end quasar luminosity function and the low-mass-end black hole-host galaxy scaling relations are very sensitive to the specific massive seed prescription. Specifically, the direct collapse model exhibits a seeding efficiency which decreases rapidly with cosmic time and produces much fewer black holes in low mass galaxies, in contrast to the original Illustris simulation. We further find that the total black hole merger rate varies by more than one order of magnitude for different seed models, with the redshift evolution of the chirp mass changing as well. Supermassive black hole merger detections with LISA and International Pulsar Timing Array may hence provide the most direct means of constraining massive black hole seed formation in the early Universe.

description: In 70's there was discovered a construction how to attach to some algebraic-geometric data an infinite-dimensional subspace in the space k((z)) of the Laurent power series. Now this construction is called the Krichever map. In e-print math.AG/9911097 A.N. Parshin suggested a generalization of the Krichever map for the case of algebraic surfaces from the point of view of 2-dimensional local fields. In this work we suggest a generalization of the Krichever map to the case of algebraic varieties of arbitrary dimension from the point of view of multidimensional local fields. For surfaces our construction coincides with the Parshin construction. Besides, we obtain new explicit acyclic resolutions of quasicoherent sheaves connected with multidimensional local fields.

description: A complete sample of 174 M giants classified by Blanco (1986) and later than subtype M0 in the NGC6522 Baade's Window clear field has been investigated to establish some general properties of cool Bulge stars. Photometric information has been obtained from the MACHO database to search for variability and, where possible, to determine periods. Near- and mid-IR magnitudes have been extracted from DENIS and ISOGAL. 46 semi-regular variables and 2 irregulars were found a mongst the 174. Many M5 and all stars M6 or later show variation, whereas earlier subtypes do not. The DENIS I-J and J-K_S colours and the luminosities of the M stars increase with M sub-class. K tends to increase with log P among M-type SR variables. Almost all the variables were detected at 7 microns during the ISOGAL programme. Excess radiation at 15 microns, indicative of heavy mass loss, is associated with very high luminosity and late spectral type. The limit of sensitivity of the ISOGAL survey was such that the non-variables were not detected. Four probable M stars not listed by Blanco (1986), two of which are semi-regular variables, were detected by ISOGAL. In the case of doubly-periodic SR variables, the longer periods have K mags which place them close to the D line of Wood (2000) in a K,log P diagram. The unusual MACHO light curve of one particular star, Blanco 26, shows the commencement of a long-period variation with an anomalously short and sharp event and appears to rule out a pulsational model for this phenomenon.

description: We review and apply Quasi Monte Carlo (QMC) and Global Sensitivity Analysis (GSA) techniques to pricing and risk management (greeks) of representative financial instruments of increasing complexity. We compare QMC vs standard Monte Carlo (MC) results in great detail, using high-dimensional Sobol' low discrepancy sequences, different discretization methods, and specific analyses of convergence, performance, speed up, stability, and error optimization for finite differences greeks. We find that our QMC outperforms MC in most cases, including the highest-dimensional simulations and greeks calculations, showing faster and more stable convergence to exact or almost exact results. Using GSA, we are able to fully explain our findings in terms of reduced effective dimension of our QMC simulation, allowed in most cases, but not always, by Brownian bridge discretization. We conclude that, beyond pricing, QMC is a very promising technique also for computing risk figures, greeks in particular, as it allows to reduce the computational effort of high-dimensional Monte Carlo simulations typical of modern risk management.

The general method of calculation of correlation functions is based on the method of determinant representations. The auxiliary Fock space and auxiliary Bose fields are introduced in order to remove the two body scattering and represent correlation functions as a mean value of a determinant of a Fredholm integral operator; the representation has a simple form for large space and time separations. In this paper we explain how to calculate the mean value in the auxiliary Fock space of asymptotic expression of the Fredholm determinant. It is necessary for the evaluation of the asymptotic form of the physical correlation functions.

New Beliefs, New Lives?: The Roles, Rights, and Responsibilities of Early Christian Women in Late Antique Egypt

Subjects: Gender

description: Late Antiquity and the associated rise of Christianity in the Roman Empire are often thought to be fraught with violence and radical change. This understanding has recently become more nuanced, and we now understand that the period was a dynamic one, involving both continuity and change. Similarly, with respect to women, it is now thought that the rise of Christianity brought with it sweeping changes, for example, in standards of morality and sexuality, but also firm continuity, for example, in law. Throughout previous centuries, the experiences of these women have been seen primarily through the lens of Christian literature, such as homilies, Church histories, and saints’ lives. As a result, the picture of an early Christian woman was a highly idealized one, of a submissive and subservient wife whose place was in the home and who was considered an image of retained guilt and an object of sexual temptation to the men around her. Since these sources are highly ideological, such a representation is less than reliable. Using legal and documentary sources, therefore, which are inherently less ideological than literary sources, this thesis analyzes the areas of continuity and change in the lives of early Christian Egyptian women in order to assess the evolution of their roles, rights, and responsibilities to understand what effect the rise of Christianity had on their day-to-day lives. That is to say, this thesis aims to answer the question: Did the rise of Christianity actually affect or change the rights or status of women in Late Antique Egypt? The thesis concludes, on the basis of the mentioned sources that early Christianity affected little meaningful change on the rights and status of women in Late Antique Egypt, but that the situation is far more complex than the normative literature suggests. Some change can be seen in understandings of sexuality, particularly in the Christian emphasis on virginity, but this change is not inherently gendered. Beyond this, there is overwhelming evidence for continuity.

description: Engineering strong interactions between optical photons is a great challenge for quantum science. Envisioned applications range from the realization of photonic gates for quantum information processing to synthesis of photonic quantum materials for investigation of strongly-correlated driven-dissipative systems. Polaritonics, based on the strong coupling of photons to atomic or electronic excitations in an optical resonator, has emerged as a promising approach to implement those tasks. Recent experiments demonstrated the onset of quantum correlations in the exciton-polariton system, showing that strong polariton blockade could be achieved if interactions were an order of magnitude stronger. Here, we report time resolved four-wave mixing experiments on a two-dimensional electron system embedded in an optical cavity, demonstrating that polariton-polariton interactions are strongly enhanced when the electrons are initially in a fractional quantum Hall state. Our experiments indicate that in addition to strong correlations in the electronic ground state, exciton-electron interactions leading to the formation of polaron polaritons play a key role in enhancing the nonlinear optical response. Besides potential applications in realization of strongly interacting photonic systems, our findings suggest that nonlinear optical measurements could provide information about fractional quantum Hall states that is not accessible in linear optical response.

description: (Abridged) We present observations of the cluster of galaxies associated with the X-ray source RX J0820.9+0752 and its dramatic central cluster galaxy (CCG) in the optical and X-ray wavebands.Unlike other cooling flow CCGs studied in detail, this system does not contain a powerful radio source at its core, and so provides us with an important example where we expect to see only the processes directly due to the cooling flow itself. Chandra observations show that the hot intracluster gas is cooling, dropping below 1.8 keV in the core. Optical images (AAT and HST) show that the central galaxy is embedded in a luminous line-emitting nebula that coincides spatially with an excess of X-ray emission, and separate, off-nucleus clumps of blue continuum that form part of a patchy structure arcing away from the main galaxy. The X-ray/H-Alpha feature is reminiscent of a filament observed in A 1795 which is suggested to be a cooling wake, produced by the motion of the CCG through the ICM. We present optical spectra of the CCG and its surroundings, and find that the continuum blobs show poperties clearly distinct from those of the surrounding nebula. Accounting for the strong intrinsic reddening and its significant variation over the extent of the line emitting region, we have fit the continuum spectra of the blobs and the nucleus using stellar spectra. We found that continuum emission from early main sequence stars can account for the blue excess light in the blobs. Kinematical properties associate the gas in the system with a nearby galaxy, suggesting some kind of tidal interaction between the two. We suggest that the secondary galaxy has moved through the cooling wake produced by the CCG, dragging some of the gas out of the wake and triggering the starbursts found in the blobs.

description: Silicon Photo-Multipliers (SiPMs) are pixelated semiconductor detectors consisting of SPADs, usually used as single-photon sensitive detectors. SiPMs are often analog devices that require separate digitization. Combining SiPMs with digital readout known from modern pixel sensors offers new possibilities like full hitmap readout, pixel masking, or fast timestamping. Due to their potentially fast time stamping capabilities, digital SiPMs are becoming an interesting contender for 4D-Tracking in High Energy Physics. At DESY such a digital SiPM was developed. It is a monolithic chip manufactured in a 150 nm CMOS process by LFoundry. The chip has a 32 × 32 pixel matrix with 76 µm × 70 µm pixels and four on-chip TDCs that allow for time stamps with a resolution of less than 100 ps. It uses the Caribou DAQ system for a fully digital readout. The chip was tested in the DESY II test beam facility with a 4 GeV electron beam. In this thesis, the analysis procedure will be described and the results for the timing performance will be discussed. The time resolution was estimated to be (46 ± 5)ps in the center of the SPAD cells, while a slower response was found at the edge of the SPAD cells.
title: An Inquiry into the Impact of the Mother Tongue on Vietnamese Adult EFL Learners’ Speech Intelligibility with Reference to Syllable Structure

description: This thesis seeks to investigate how the mother tongue of 50 Vietnamese university EFL students impacts on their intelligibility in oral communication, with specific reference to syllable structure. The assumption is that there is interference between the native language (L1) and the new language (L2), and negative transfer of native oral usage habits to the target language, which affects the students’ intelligibility. Additionally, the current study also examines other potential reasons for the participating students having pronunciation errors. Mixed methods for data collection and analysis – a quantitative approach and a qualitative approach – have been used to explore these issues. The quantitative data and results provide the general picture of the research problem, whereas further analysis and rich data gained through qualitative data collection have refined, extended, and explained the intelligibility problem of Vietnamese English speakers in depth. The findings show that Vietnamese adult EFL speakers’ intelligibility is so low and that syllable structure errors impact on the students’ speech intelligibility. The syllable structure errors are generally caused by the application of Vietnamese syllable structure in the pronunciation of English syllables in the pronunciation tests. For instance, Vietnamese open syllables were used by the 50 informants to articulate English close syllables during the pronunciation tests.
Do Critical Audit Matter Disclosures Impact Investor Behavior?

description: The Public Company Accounting Oversight Board (PCAOB) has recently required auditors to disclose critical audit matters (CAMs), which are financial statement matters that involve especially challenging, subjective, or complex auditor judgments. The PCAOB contends that CAMs will increase the decision usefulness of the auditor’s report and indirectly benefit investors by increasing audit and financial reporting quality. I examine whether investors react to CAM disclosures and whether they perceive any change in adopting firms’ financial reporting quality. Using a difference-in-differences design, I find that (1) while there is no significant stock price reaction to CAMs on average, investors react negatively to CAMs disclosed by firms with high levels of short interest; (2) there is a significant increase in the quarterly earnings response coefficient for adopting firms. The effect is driven by big-N audit firms, and increases with the number of CAMs reported. Collectively, the evidence suggests that investors use CAMs to confirm their pre-existing opinions about a firm, and that they perceive an improvement in audit quality and financial reporting reliability due to the CAM disclosure requirement.

description: Recently, it was shown that dissipative quantum systems with three or more levels are able to synchronize to an external signal, but it was stated that it is not possible for two-level systems as they lack a stable limit cycle in the unperturbed dynamics. At the same time, several papers, demonstrate, under a different definition of what is synchronization, that the latter is possible in qubits, although in different models which also include other elements. We show how a quantum two-level system can be understood as containing a valid limit cycle as the starting point of synchronization, and that it can synchronize its dynamics to an external weak signal. This is demonstrated by analytically solving the Lindblad equation of a two-level system coupled to an environment, determining the steady state. This is a mixed state with contributions from many pure states, each of which provides a valid limit cycle. We show that this is sufficient to phase-lock the dynamics to a weak external signal, hence clarifying synchronization in two-level systems. We use the Husimi Q representation to analyze the synchronization region, defining a synchronization measure which characterizes the strength of the phase-locking. Also, we study the stability of the limit cycle and its deformation with the strength of the signal in terms of the components of the Bloch vector of the system. Finally, we generalize the model of the three-level system from in order to illustrate how the stationary fixed point of that model can be changed into a limit cycle similar to the one that we describe for the two-level system.

description: This article deals with the problems of lexicology and stylistics in linguistics which studies the graduonimic words which are one of the important field of the language. It is filed that  the degree of the gradation related with the corresponding factor on the scale, and for that reason categorical precise gradational standards in the language. The common degree or norm of a person a commonly has no extraordinary potential of determination. This function is stated by way of many researchers. It is really worth noting that the indications of the highlighted organizations differ, first of all, in the diploma of graduality of the sign, that is, they occupy extraordinary factors of the scale, growing and reducing in relation to the center factor (norm).

description: We show that various models of the elliptic Calogero-Moser systems are accompanied with an isomonodromic system on a torus. The isomonodromic partner is a non-autonomous Hamiltonian system defined by the same Hamiltonian. The role of the time variable is played by the modulus of the base torus. A suitably chosen Lax pair (with an elliptic spectral parameter) of the elliptic Calogero-Moser system turns out to give a Lax representation of the non-autonomous system as well. This Lax representation ensures that the non-autonomous system describes isomonodromic deformations of a linear ordinary differential equation on the torus on which the spectral parameter of the Lax pair is defined. A particularly interesting example is the ``extended twisted $BC_\ell$ model'' recently introduced along with some other models by Bordner and Sasaki, who remarked that this system is equivalent to Inozemtsev's generalized elliptic Calogero-Moser system. We use the ``root type'' Lax pair developed by Bordner et al. to formulate the associated isomonodromic system on the torus.

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.

An all order exact result for the anomalous dimension of the scalar primary in Chern Simons Vector Models

description: We present a conjecture for the leading $1/N$ anomalous dimension of the scalar primary operator in $U(N)_k$ Chern-Simons theories coupled to a single fundamental field, to all orders in the t'Hooft coupling $λ=\frac{N}{k}$. Following this we compute the anomalous dimension of the scalar in a Regular Bosonic theory perturbatively at two-loop order and demonstrate that matches exactly with the result predicted by our conjecture. We also show that our proposed expression for the anomalous dimension is consistent with all other existing two-loop perturbative results, which constrain its form at both weak and strong coupling thanks to the bosonization duality. Furthermore, our conjecture passes a novel non-trivial all loop test which provides a strong evidence for its consistency.

Canonical Structure of Classical Field Theory in the Polymomentum Phase Space

description: Canonical structure of the space-time symmetric analogue of the Hamiltonian formalism in field theory based on the De Donder-Weyl (DW) theory is studied. In $n$ space-time dimensions the set of $n$ polymomenta is associated to the space-time derivatives of field variables. The polysymplectic $(n+1)$-form generalizes the simplectic form and gives rise to a map between horizontal forms playing the role of dynamical variables and vertical multivectors generalizing Hamiltonian vector fields. Graded Poisson bracket is defined on forms and leads to the structure of a Z-graded Lie algebra on the subspace of the so-called Hamiltonian forms for which the map above exists. A generalized Poisson structure arises in the form of what we call a ``higher-order'' and a right Gerstenhaber algebra. Field euations and the equations of motion of forms are formulated in terms of the graded Poisson bracket with the DW Hamiltonian $n$-form $H\vol$ ($\vol$ is the space-time volume form and $H$ is the DW Hamiltonian function). A few applications to scalar fields, electrodynamics and the Nambu-Goto string, and a relation to the standard Hamiltonian formalism in field theory are briefly discussed. This is a detailed and improved account of our earlier concise communications (hep-th/9312162, hep-th/9410238, and hep-th/9511039).

Many-body quantum dynamics of initially trapped systems due to a Stark potential --- thermalization vs. Bloch oscillations

description: We analyze the dynamics of an initially trapped cloud of interacting quantum particles on a lattice under a linear (Stark) potential. We reveal a dichotomy: initially trapped interacting systems possess features typical of both many-body-localized and self-thermalizing systems. We consider both fermions ($t$-$V$ model) and bosons (Bose-Hubbard model). For the zero and infinite interaction limits, both systems are integrable: we provide analytic solutions in terms of the moments of the initial cloud shape, and clarify how the recurrent dynamics (many-body Bloch oscillations) depends on the initial state. Away from the integrable points, we identify and explain the time scale at which Bloch oscillations decohere.
Spatial vulnerability assessments of rural households to climate change in Nigeria: Towards evidence-based adaptation policies

description: The ability to identify and understand the extent of vulnerability to climate change is an essential pre-requisite for reducing climate change impacts. This is because a reasonable starting point for any climate adaptation process is to assess the vulnerability of the target community or stakeholders. Consequently, the study assesses the spatial patterns of vulnerability to climate change in Nigeria in order to provide empirical evidence necessary for climate change adaptation policies and strategies in the country. The data for the research were obtained from Annual Abstract of Statistics 2009, General Household Survey 2006 and the Nigerian Core Welfare Indicator Questionnaire Survey (CWIQ) 2006. An integrated assessment approach was employed to analyse vulnerability of rural households’ data comprising socio-economic and biophysical indicators aggregated at state levels. The results show that rural households in the northern states are more vulnerable because of greater exposure to climate induced environmental hazards and low adaptive capacity which results from poor local economies, inadequate healthcare and education systems and poor infrastructure. Based on the results of the assessment, measures to prioritise and target the vulnerable states for appropriate climate change adaptation within the context of sustainable rural development were suggested.
