description: We study the evolution of the physical parameter values defined at the sub-planckian energies to values at low energies. The Wilson action is the basis of the research. The presence of the compact extra dimensions has two consequences. The positive point is that the integration over extra dimensions is a promising way to substantially reduce the parameters to be comparable with the observational values. On the other hand, the discreteness of the energy levels of compact extra dimensions complicates the analysis. This difficulty can be overcome with the truncated Green functions.

description: The use of semantic web technologies within scientific research has slowly gained momentum over the last twenty years. Researchers have realised that these technologies are key to dealing with large volumes of data, and that they enable better organisation of scientific documents and practices. However, we still have a long way to go before these technologies realise their true potential, and this is as much a human endeavour as a technological one. This talk will discuss the affordances of the semantic web, demonstrating where it can be used across the entire scientific research process; but it will also note some lessons learned throughout the last twenty years, and provide some recommendations for going forward in the future.

Role of notch signaling in angiogenesis and breast cancer
Creators: name: Leong, Kevin G.
Publisher: name: University of British Columbia

description: The Notch family of transmembrane receptors consists of four members in mammals, Notchl through Notch4. Upon ligand binding, Notch receptors become activated and participate in intracellular signaling pathways that regulate cell fate decisions. Notchl-3 are expressed on numerous cell types. Because Notch4 is primarily expressed on endothelial cells, we postulated that Notch4 activation would modulate cell fate decisions in an endothelial-specific manner. Angiogenesis, the sprouting of endothelial cells from pre-existing microvessels, requires modulation of the endothelial cell phenotype. We have identified a role for Notch4 activation in the regulation of angiogenesis. Expression of activated Notch4 inhibits endothelial sprouting in vitro and angiogenesis in vivo. Activated Notch4 does not inhibit endothelial cell migration through the extracellular matrix protein fibrinogen, whereas migration through collagen is inhibited. Activated Notch4 increases endothelial cell adhesion to collagen by modulating the affinity state of cell-surface collagen receptors belonging to the pi integrin family. Specifically, activated Notch4 converts pi integrin from an inactive, non-ligand-binding state to an active, high-affinity conformation. Our findings suggest that Notch4 activation in endothelial cells inhibits angiogenesis in part by promoting pi integrin-mediated adhesion to the underlying matrix. Although Notch signaling regulates normal cellular processes, increasing evidence suggests a role for aberrant Notch signaling in cellular transformation. During tumor progression, epithelial tumor cells often acquire a mesenchymal phenotype through epithelial-tomesenchymal transition (EMT), a process that promotes invasion and dissemination of cancer cells. In human breast cancer, EMT directly correlates with downregulated expression of the adherens junction protein epithelial (E)-cadherin. Given that Notch pathway elements are expressed at sites of epithelial-mesenchymal cell-cell interactions during embryogenesis and within primary human breast tumors, we investigated whether Notch signaling would modulate E-cadherin expression in human breast cells. Our studies identify activated Notch signaling as a novel mechanism for the downregulation of E-cadherin expression in normal human breast epithelial cells. In human breast tumor xenografts lacking E-cadherin expression, we show that a soluble inhibitor of Notch signaling attenuates E-cadherin promoter methylation and induces Ecadherin re-expression. This re-induction of E-cadherin in turn inhibits p-catenin nuclear accumulation, resulting in a marked reduction in breast tumor growth and metastasis.

description: Experts generally agree that increased concentrations of greenhouse gases (GHGs) in the atmosphere will result in changes in the earth‘s climate. Increased attention by policy makers to this threat of global climate change has brought with it considerable attention to the possibility of using forests as a means of sequestering and reducing emissions of carbon dioxide in the atmosphere. As globally important storehouses of carbon, forests play a critical role in influencing the Earth's climate. Reducing GHGs can be achieved by controlling and avoiding land use changes. In many parts of the world, forests are being rapidly cleared for agriculture or pasture, destructively logged, and degraded by human-set fires. When forests are degraded or cleared, their stored carbon is released back to the atmosphere during harvest and through respiration, thus these forests are net contributors of carbon to the atmosphere. Forestry is an important sector in Kenya. The long term development of the forestry sector will definitely affect the future amounts of carbon sequestration and emission of the country. The purpose of this study was to provide an understanding of the role that Kakamega forest can play in the mitigation of climate change through carbon sequestration. It evaluates potential economic value of carbon sequestration of Kakamega forest as well as the potential of the forest to participate in carbon trading. In addition, the study investigated the status of the carbon stock in the forest, based on the biomass stock. The study adopted the tobit model to estimate the determinants of the total amount carbon that can be sequestered by trees in farms. The study confirms the huge atmospheric CO2 that can be offset by the Kakamega forest, indicating the potential of Kenya to participate in carbon trading for both its economic and environmental benefit. The results further indicate that the major determinants of the amount of carbon that can be sequestered by trees in farms are the sex of the respondent, position of the respondent in the household, source of income, tenure status of the farm, and perception on whether trees can reduce global warming. The results of the study can expedite policy decisions regarding Kenya‘s participation in carbon trading through the Clean Development Mechanism (CDM) as well as providing benefits to the national forestry sector, as well as the private owners and participants in the community forestry, in terms of an overall increase in income, and achieving self-sufficiency.

description: There has been a growing debate regarding the role of the government and the effects of agricultural policies and interventions on agricultural markets. This therefore prompted this study to analyse the role of Malawi Agricultural Commodity Exchange (MACE) project as a market-enhancing intervention on aggregate market performance in Malawi using cointegration methods. MACE was introduced to improve agricultural market functioning through market information system. The study specifically examined the extent of spatial rice market integration, causality relationships among spatially separated markets and the dynamic adjustments of rice price series. The study used monthly price series data from 1994 to 2007 obtained from the ministry of agriculture. The data was divided into three sets; full sample, Pre-MACE and Post-MACE. Stationarity tests were done and it was noted that Salima and Bangula for full sample and Chitipa for Pre and Post-MACE price series were stationary in levels implying that these markets did not share the long-term trend with the major urban centres in Malawi in their respective samples. Cointegration results have shown that spatial rice market integration in Malawi is on average marginally improving. Compared to Pre-MACE period, cointegration and interdependence among markets appeared to be increasing during the Post-MACE era. Cointegration has also revealed that rice markets have been operating as a unified market system over the period of study. However, the study left out other factors affecting market integration due to financial and time constraints hence this improvement can not be fully accredited to MACE intervention. Nevertheless, since the aggregate picture observed in this study is an improvement of market integration the study recommends a promotion of MACE intervention to reach even more remote areas. The project needs to consider collecting and disseminating other market information such as trade flows, transaction costs and transfer costs. The study also recommends that further studies on market integration should take care of other structural determinants of market integration such as marketing infrastructure e.g. transportation, government policies and should consider application of the threshold autoregressive models (catering for transaction costs).

description: The purpose of this paper is to study optimality of circular neighbor-balanced block designs when neighbor effects are present in the model. In the literature many optimality results are established for direct effects and neighbor effects separately, but few for total effects, that is, the sum of direct effect of treatment and relevant neighbor effects. We show that circular neighbor-balanced designs are universally optimal for total effects among designs with no self neighbor. Then we give efficiency factors of these designs, and show some situations where a design with self neighbors is preferable to a neighbor-balanced design.

Risk and Uncertainty

description: Farmers face many risks which arise from natural, economic and socio-political environments. Risk sharing institutions like national insurance and credit schemes that help reduce the burden of risk to society are weak in Uasin Gishu county. Private sector insurance products are still in their developing stages and this has prompted farmers to turn to self insurance strategies that include diversification and social mechanisms for coping with risk. Off-farm investment is one of the diversification strategies whose prevalence and effectiveness in risk management have not been evaluated. This study sought to determine risk attitudes of farmers, to identify the determinants of off-farm investments and to investigate the effectiveness of off-farm investments in risk management. Data was collected from 100 randomly selected farm households. The ELCE method was used and exponential utility functions fitted by the method of nonlinear least squares and used to estimate the coefficients of absolute risk aversion. A logit model was used to identify determinants of off-farm investments. Effectiveness of off-farm investments in risk management was assessed by simulating the effect of replacing the weight of off-farm income with that of farm income on the coefficient of variation of total income. Results indicated that the major risks of concern to farmers were drought, market/price, pests and diseases and institutional risks with prevalence rates of 59, 34, 4 and 3% respectively. All the farmers in the study were risk averse. Years of experience in farming, employment income, gender and farm income significantly determined off-farm investment decisions. Simulation results showed that off-farm investment income reduces risk. Government policies and institutional mechanisms that reduce risk (such as crop insurance and irrigation technologies) and those that facilitate farmers‟ access to assets like off-farm investments in order to manage risks in farming are required.

description: We enumerate plane complex algebraic curves of a given degree with one singularity of any given topological type. Our approach is to compute the homology classes of the corresponding equisingular strata in the parameter spaces of plane curves. We suggest a recursive procedure, which is based on the intersection theory combined with liftings and degenerations. The procedure computes the homology class in question whenever a given singularity type is defined. Our method does not require the knowledge of all the possible deformations of a given singularity.

description: Booth and Cox proposed the E(s^2) criterion for constructing two-level supersaturated designs. Nguyen [Technometrics 38 (1996) 69-73] and Tang and Wu [Canad. J. Statist 25 (1997) 191-201] independently derived a lower bound for E(s^2). This lower bound can be achieved only when m is a multiple of N-1, where m is the number of factors and N is the run size. We present a method that uses difference families to construct designs that satisfy this lower bound. We also derive better lower bounds for the case where the Nguyen-Tang-Wu bound is not achievable. Our bounds cover more cases than a bound recently obtained by Butler, Mead, Eskridge and Gilmour [J. R. Stat. Soc. Ser. B Stat. Methodol. 63 (2001) 621-632]. New E(s^2)-optimal designs are obtained by using a computer to search for designs that achieve the improved bounds.

description: Residential energy consumption (REC) is the second largest energy use category (10%) in China and urban residents account for most of the REC. Understanding the underlying drivers of variations of urban REC thus helps to identify challenges and opportunities and provide advices for future policy measures. This paper applies the logarithmic mean Divisia index (LMDI) to a decomposition of China’s urban REC during the period of 1998-2007 at disaggregated product/activity level using data collected from a wide range of sources. Our results have shown an extensive structure change towards a more energy-intensive household consumption structure as well as an intensive structure change towards high-quality and cleaner energy such as electricity, oil, and natural gas, which reflects a changing life style and consumption mode in pursuit of a higher level of comfort, convenience and environmental protection. We have also found that China’s price reforms in the energy sector have contributed to a reduction of REC while scale factors including increased urban population and income levels have played a key role in the rapid growth of REC. We suggest that further deregulation in energy prices and regulatory as well as voluntary energy efficiency and conservation policies in the residential sector should be promoted.

description: In the past three decades, Chinese electricity industry has experienced a series of regulatory reforms serving different purposes at different stages. In 2002, the former vertically integrated electricity utility - the State Power Corporation (SPC) – was divested and the generation sector was separated from the transmission and distribution networks in an effort to improve production efficiency. In this paper we study the impact of the reform on efficiency of fossil-fired power plants using plant-level data during 2000-2008. Our results from the data envelopment analysis (DEA) and panel regressions show that: 1) the total factor productivity (TFP) growth mainly comes from technological change; 2) the technical efficiency of previously SPC-managed power plants is converging to that of better-performing independent power producers (IPPs); 3) capacity utilization and unit size are significant factors affecting changes in technical efficiency and the pattern of converging technical efficiency between the two kinds of power plants; 4) most plants operate at increasing returns to scale indicating further cost savings could be achieved through increasing output.

description: Using the fully-relativistic screened Korringa-Kohn-Rostoker method I study the orbital magnetism in the half-metallic Heusler alloys. Orbital moments are almost completely quenched and they are negligible with respect to the spin moments. The change in the atomic-resolved orbital moments can be easily explained in terms of the spin-orbit strength and hybridization effects. Finally I discuss the orbital and spin moments derived from X-ray magnetic circular dichroism experiments.
The role of ICAM-1 in myocardial dysfunction during sepsis and ischemia-reperfusion injury
Creators: name: Yousefzadeh-Davani, Ehsan
Publisher: name: University of British Columbia
Year: 2009

description: Intramyocardial inflammation occurs in various types of cardiovascular diseases including ischemia-reperfusion, myocarditis, during orthotopic heart transplant rejection, and during sepsis-induced myocardial dysfunction. Intramyocardial inflammation results in increased expression of ICAM-1 on cardiac tissue. ICAM-1 can interact with its ligands including CD11/CD14 receptors on inflammatory cells, and fibrinogen leading to activation of intracellular signaling cascades. To test this hypothesis that ICAM-1 activation on cardiac tissue can trigger signaling which leads to decreased cardiac contractility we used three different in vitro (cardiomyocytes, polymorphonuclear leukocytes (PMN) and fibrinogen co-culture), in vivo (cardiac contractility measurement using micro-catheter) and ex vivo (reperfusion of isolated heart) methods. Cardiomyocyte ICAM-1 -binding by activated PMN, by activated and killed PMNs, and by ICAM-1 cross-linking antibodies decreased cardiomyocytes contractility. In vivo, inducing severe cardiac inflammation by LPS injection decreases cardiac contractility by 58 ± 4% (using end systolic elastance) and increases ICAM-1 expression on cardiac tissue by 2.35 fold compared to control. Morphometery of cardiac vessels indicated increased intravascular PMNs after LPS injection but the number of interstitial PMNs were not different compared to control excluding the role of PMN adhesion in ICAM-1 activation in sepsis. This led to the next hypothesis that fibrinogen can interact with ICAM-1 after LPS injection. Immunohistochemistry staining indicates increased interstitial fibrinogen infiltration six hours after LPS injection supporting the interaction of ICAM-1 and fibrinogen during sepsis. Incubation of cardiomyocytes with fibrinogen decreased cardiomyocytes contractility. This effect of fibrinogen was abolished in the presence of anti ICAM-1 antibody. Treatment of isolated heart with IGF-1 decreases ICAM-1 expression by 2 fold (p<0.01), increases cardiac contractility and heart rate, and decreases CPK during reperfusion compared to TNFα. We conclude that PMN and fibrinogen interact with cardiomyocytes ICAM-1. Fibrinogen infiltrates into the myocardial interstitial space during sepsis and decreases cardiac contractility through adhesion to ICAM-1 receptor on the cardiomyocyte membrane. IGF-1 can be used as a therapeutic intervention to decrease ICAM-1 expression thereby protecting the heart from further injury during cardiac inflammation.

description: The worldwide spread of COVID-19 has called for fast advancement of new modelling strategies to estimate its unprecedented spread. Here, we introduce a model based on the fundamental SIR equations with a stochastic disorder by a random exchange of infected populations between cities to study dynamics in an interacting network of epicentres in a model state. Although each stochastic exchange conserves populations pair-wise, the disorder drives the global system towards newer routes to dynamic equilibrium. Upon controlling the range of the exchange fraction, we show that it is possible to control the heterogeneity in the spread and the co-operativity among the interacting hotspots. Data of collective temporal evolution of the infected populations in federal states of Germany validate the qualitative features of the model.

description: Deteriorating food security status is primarily a local phenomenon resulting from failures in food systems and inadequate incomes. Technological advances in agriculture have led to declining long-term trends in food prices, which have assisted in improving diets. It is projected that in the first half of the twenty-first century, food production increases will have a difficult time keeping pace with the increase in population, leading to increased incidents where local price spikes for food lead to deteriorations in the food security status of many locally resident individuals. International trade in food products will be key to mitigating the effects of local food systems failures.

We use bosonization techniques to describe the gapped spin chain and then use the Thermodynamic Bethe Ansatz to obtain quantitative results for the thermodynamics of the spin-Peierls system in a whole range of temperature. This allows us to predict the behavior of the specific heat and the magnetic susceptibility in the entire dimerized phase. We study the effect of small magnetic fields on the transition. Moreover, we obtain the parameters of the Landau-Ginzburg theory describing this continuous phase transition near the critical point.

description: The global neutron monitor network has been successfully used over several decades to study cosmic ray variations and fluxes of energetic solar particles. Nowadays, it is used also for space weather purposes, e.g. alerts and assessment of the exposure to radiation. Here, we present the current status of the global neutron monitor network. We discuss the ability of the global neutron monitor network to study solar energetic particles, specifically during large ground level enhancements. We demonstrate as an example, the derived solar proton characteristics during ground level enhancements GLE $\#$5 and the resulting effective dose over the globe at a typical commercial jet flight altitude of 40 kft ($\approx$ 12 200m) above sea level. We present a plan for improvement of space weather services and applications of the global neutron monitor network, specifically for studies related to solar energetic particles, namely an extension of the existing network with several new monitors. We discuss the ability of the optimized global neutron monitor network to study various populations of solar energetic particles and to provide reliable space weather services.

title: Shared control: origins and consequences of integrated military capabilities: a dissertation on the integrated defence cooperation initiatives of the Netherlands and Germany and their impact on the core state powers of government
Creators: name: Miethke, Lars
Publisher: name: London School of Economics and Political Science (LSE)
Year: 2022

description: The governments of the Netherlands and Germany are paving the way for a new form of defence cooperation in Europe, the integration of parts of their armed forces. Both governments pursue such integrations efforts with multiple partners to address acute capability shortfalls and the degree of integration of these bilateral and multilateral efforts creates serious dependencies between the participating governments. The impact on Dutch and German core state powers goes far beyond the control of the cooperating forces and touches, for example, on the budgetary authorities of their parliaments or the broader foreign policy of each government. Despite these dependencies, the trend to further deepen existing cooperations and initiate new partnerships via G2G agreements continues. In this dissertation, I examine these integrated defence cooperation efforts of German and Dutch armed forces through the lens of International Relations theory and ask why these two governments have agreed to share their sovereign powers. Some have argued that states pursue defence cooperation to strengthen their unilateral military power in the face of a threat or that the socialisation of elite decision-makers in international organisations preceded government decisions to cooperate. However, my field research shows that the decision to share core state powers is the result of a calculated decision-making process that generates distinct political, economic, and military operational benefits for each government. The benefits are particularly pronounced as regards their contribution to the absolute military capabilities of the EU and NATO and hence the absolute multilateral security of their members. I argue that the decision to share core state powers is theoretically best understood and described in terms of a liberal intergovernmentalist framework rather than as a product of elite socialisation or neorealist threat balancing.

description: We study the transfer matrix of the 8 vertex model with an odd number of lattice sites $N.$ For systems at the root of unity points $η=mK/L$ with $m$ odd the transfer matrix is known to satisfy the famous ``$TQ$'' equation where ${\bf Q}(v)$ is a specifically known matrix. We demonstrate that the location of the zeroes of this ${\bf Q}(v)$ matrix is qualitatively different from the case of even $N$ and in particular they satisfy a previously unknown equation which is more general than what is often called ``Bethe's equation.'' For the case of even $m$ where no ${\bf Q}(v)$ matrix is known we demonstrate that there are many states which are not obtained from the formalism of the SOS model but which do satisfy the $TQ$ equation. The ground state for the particular case of $η=2K/3$ and $N$ odd is investigated in detail.

The algebraic setting is mapped to the algebra of functions of commuting variables with a suitable star-product. Fields are elements of this function algebra. As an example, the Klein-Gordon equation is defined and derived from an action.

description: Object: To assess the possible influence of third order shim coils on the behavior of the gradient field and in gradient-magnet interactions at 7T and above.

Materials and methods: Gradient impulse response function measurements were performed at 5 sites spanning field strengths from 7T to 11.7T, all of them sharing the same exact whole-body gradient coil design. Mechanical fixation and boundary conditions of the gradient coil were altered in several ways at one site to study the impact of mechanical coupling with the magnet on the field perturbations. Vibrations, power deposition in the He bath and field dynamics were characterized at 11.7T with the 3rd order shim coils connected and disconnected inside the Faraday cage.

Results: For the same whole-body gradient coil design, all measurements differed greatly based on the 3rd order shim coil configuration (connected or not). Vibrations and gradient transfer function peaks could be affected by a factor of 2 or more, depending on the resonances. Disconnecting the 3rd order shim coils at 11.7T also suppressed almost completely power deposition peaks at some frequencies.

Discussion: Third-order shim coil configurations can have major impact in gradient-magnet interactions with consequences on potential hardware damage, magnet heating and image quality going beyond EPI acquisitions.
The syntax of WH-expressions as variables in Thai
Creators: name: Ruangjaroon, Sugunya
Publisher: name: University of British Columbia
Year: 2009

description: This dissertation presents an in-depth examination of Thai wh-expression as variables. I claim that wh-expressions are variables with no inherent interrogative force. As variables, they acquire different interpretations in different contexts. A syntactic relation between the operator and the variable is implemented in terms of the probe-goal relation (Chomsky 2000). The probe-goal relation is established by the operation of Match. In Thai, a goal (as a variable) is "underspecified" for featural content. A feature specified on the probe is copied onto the underspecified goal, thereby satisfying feature matching. In wh-contexts, the probe is identified as a covert interrogative Q[[sub wh]]. The [wh] feature of the probe Q is copied onto the underspecified goal. I argue that the probe-goal relation is established via Match (without Move). The covert Q[[sub wh]] probe is base-generated in C. In the context of negation, a goal matches the [neg] feature on the Neg probe, hence functioning as a Negative Polarity Item (NPI). In a yes-no construction, the goal matches the [polarity] feature on the Q[[sub polarity]] probe, functioning as an Existential Polarity Item (EPI). The probe-goal relation is predictably constrained by the c-command relation and locality conditions. In addition to wh in-situ, it appears there is also partial and long-distance wh-movement in Thai. However, contrary to superficial appearances, I argue that the probe-goal relation in Thai does not involve Move. In particular, I show that apparent cases of movement actually involve two distinct types of cleft constructions. The first I analyze as reduced contrastive wh-clefts with bare wh-expressions. The second I analyze as reduced identificational wh-clefts with D-linked wh-expressions. Semantically and syntactically, contrastive wh-clefts differ from identificational wh-clefts. Contrastive wh-clefts are formed with the overt copula (pen), a definite marker (t[sup h]î) and a nominalized clause. Identificational wh-clefts, on the other hand, are formed with the overt copula (k[sup h]i) and a relative clause.
Complexity regularization via localized random penalties

description: In this article, model selection via penalized empirical loss minimization in nonparametric classification problems is studied. Data-dependent penalties are constructed, which are based on estimates of the complexity of a small subclass of each model class, containing only those functions with small empirical loss. The penalties are novel since those considered in the literature are typically based on the entire model class. Oracle inequalities using these penalties are established, and the advantage of the new penalties over those based on the complexity of the whole model class is demonstrated.

description: We study the holographic dual to $c$-extremization for 2d $(0,2)$ superconformal field theories (SCFTs) that have an AdS$_3$ dual realized in Type IIB with varying axio-dilaton, i.e. F-theory. M/F-duality implies that such AdS$_3$ solutions can be mapped to AdS$_2$ solutions in M-theory, which are holographically dual to superconformal quantum mechanics (SCQM), obtained by dimensional reduction of the 2d SCFTs. We analyze the corresponding map between holographic $c$-extremization in F-theory and $\mathcal{I}$-extremization in M-theory, where in general the latter receives corrections relative to the F-theory result.

description: Various aspects of the Higgs boson phenomenology of the Minimal Supersymmetric Standard Model (MSSM) are reviewed. Emphasis is put on the effects of higher-order corrections. The masses and couplings are discussed in the MSSM with real and complex parameters. Higher-order corrections to Higgs boson production channels at a prospective e+ e- linear collider are investigated. Corrections to Higgs boson decays to SM fermions and their phenomenological implications for hadron and lepton colliders are explored.

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.
