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.

Philosophical, theoretical and experimental propositions on wavefunction collapse
Creators: name: Goldwater, Daniel
Publisher: name: Imperial College London
Year: 2018

description: Collapse models are posited as a resolution to the measurement problem. On one level, they offer a clear, simple and testable resolution to an age-old problem. Yet at the same time, they raise many new questions of their own - what is the origin of the putative noise field? What are its properties, and why ought it couple to wavefunctions in this particular way, inducing collapse in some analogue of the position basis? How might these models be extended to the realm of relativity without incurring catastrophe? What sort of image of the world do they deliver? In this thesis we begin with a philosophical exploration of collapse theories. We examine, in detail, the relationship between stochastic noise fields and the evolution of the wavefunction - shedding light both on the solutions offered by collapse models and the new issues which they raise. We discuss the possibilities for constructing an ontology based on these theories, and look at possible implications for the arrow of time and the meaning of causation. This in turn motivates the development of protocols for experiments which might be capable of probing these models; to new degrees in some senses, and in new forms in others. We develop a comprehensive theoretical model of a levitated nanosphere held in an electric quadrupole trap, and find the limits to which this can probe the characteristic collapse rate $\lambda$ and correlation length $r$ of collapse models. Further, we develop a novel treatment of this scenario in the style of open quantum systems, and show that such an apparatus can constitute a general quantum spectrometer, capable of characterising arbitrary correlation functions for a noise source coupled to the oscillator - whether that noise be invoked by collapse models or other, more mundane sources. Finally, we utilise numerical simulations of trap dynamics to demonstrate the capabilities of electronic feedback cooling - showing that quantum states ought to be achievable without the use of optics. This work is motivated by a desire to understand the world, and specifically to address some of the paradoxes which arise when we try to use quantum mechanics to do so. We have aimed to follow what we see as best practice in physics - from a motivation within philosophy, to the development of theory capable of meeting that philosophy, to the design of experiments which would be able to speak to the relationship between that theory and the world.

Chemical Abundances of Planetary Nebulae in the Bulge and Disk of M31

description: We derive abundances and central star parameters for 15 planetary nebulae (PNe) in M31: 12 in the bulge and 3 in a disk field 14 kpc from the nucleus. No single abundance value characterizes the bulge stars: although the median abundances of the sample are similar to those seen for PNe in the LMC, the distribution of abundances is several times broader, spanning over 1 decade. None of the PNe in our sample approach the super metal-rich ([Fe/H] ~ +0.25) expectations for the bulge of M31, although a few PNe in the sample of Stasinska, Richer, & Mc~Call (1998) come close. This [O/H] vs [Fe/H] discrepancy is likely due to a combination of factors, including an inability of metal-rich stars to produce bright PNe, a luminosity selection effect, and an abundance gradient in the bulge of M31. We show that PNe that are near the bright limit of the [OIII] 5007 planetary nebula luminosity function (PNLF) span nearly a decade in oxygen abundance, and thus, support the use of the PNLF for deriving distances to galaxies (Jacoby 1996) with differing metallicities. We also identify a correlation between central star mass and PN dust formation that partially alleviates any dependence of the PNLF maximum magnitude on population age. Additionally, we identify a spatially compact group of 5 PNe having unusually high O/H; this subgroup may arise from a recent merger, but velocity information is needed to assess the true nature of the objects.

Torsional guided wave EMAT for pipeline monitoring
Creators: name: Herdovics, Balint
Publisher: name: Imperial College London
Year: 2018

description: Non-destructive tests are performed regularly to asses a component's fitness for service. Guided wave ultrasound inspection is a well-established method for non-destructive testing of structures. As the propagation of guided waves can cover larger areas, fewer measurements are required to inspect large structures. While the sensitivity is lower, this enables rapid screening of structures for large defects. Piezoelectric guided wave transducers are widely available, but they require surface preparation and bonding. There is a concern, that adhesive property changes, especially when exposed to repeated temperature changes, can result in output signal variability. The highest possible stability is required for improved sensitivity, therefore the aim of this project is to investigate EMATs, which are non-contact and might be more stable. The EMAT's excitation mechanism is contactless, therefore it can potentially offer a good alternative for the bonded piezoelectric transducers. The thesis presents the design, simulation and testing of a torsional guided wave EMAT, which excites the fundamental torsional guided wave mode. A high temperature version of the transducer was designed, and signals were recorded at temperatures above 200°C. The benefit of the permanently installed transducers is that they can deliver more repeatable measurement data, as uncertainties associated with the installation process are more likely to remain constant. However, temperature variations affect the recorded signal, and they need to be compensated for. Previous work has focused on the compensation of propagation speed in ultrasonic signals. This thesis investigates the benefit of additionally compensating the transducer induced waveform changes. By adding the extra compensation term, significant improvement is reached at the location of pipe features. Structural Health Monitoring (SHM) systems rely on stable transducers to guarantee the required sensitivity for damage detection. The stability of the EMAT prototype was evaluated during a 1.5-year long test where the transducer and the pipe was exposed to repeated temperature variations. The results show good performance (the changes at the coherent noise level are less, than 0.8% of the signal amplitude), further improvements to transducer design that potentially increase the stability near reflectors are suggested. These can form the basis for future work.
Dynamic portfolio optimization with credit risk

description: Credit risk, which considers the risk of loss resulting from a counterparty's failure to meet contractual obligations, was not properly studied in the literature of dynamic portfolio optimization problem until the 2008-2009 financial crisis. This thesis is devoted to the dynamic portfolio optimization with credit risk. Two main topics are studied in this thesis. In the first topic, we consider a utility maximization problem with defaultable stocks and looping contagion risk. We assume that the default intensity of one company depends on the stock prices of itself and other companies, and the default of the company induces immediate drops in the stock prices of the surviving companies. Under such looping contagion risk framework, we prove that the value function is the unique viscosity solution of the HJB equation. We also perform some numerical tests to compare and analyse the statistical distributions of the terminal wealth of log utility and power utility based on two strategies, one using the full information of intensity process and the other a proxy constant intensity process. The numerical tests confirm that modeling looping contagion risk properly is important, especially in financial distressed period. The second topic is on dynamic portfolio optimization with contingent convertible (CoCo) bond. As a new type of hybrid product, CoCo bond has the interesting feature that converting from debt to equity is contingent. We model the conversion of CoCo bond by reduced-form approach and assume that the conversion intensity is a deterministic function of the coupon rate and the issuing bank's stock price. Theoretically, we construct the viscosity solution representation between the value function and the corresponding HJB equation. Practically, we compare the performance between investing into CoCo bond and the issuing bank's stock. We analyse the statistical distributions of terminal wealth of log utility and power utility based on these two investment choices. Our simulation results show that, the CoCo bond holders bear more loss than equity holders if conversion occurs. However, investing into CoCo bond gets more profit (mean) while bearing less market risk (volatility) as long as conversion does not occur.

description: While the mechanical behavior of noble nanoporous metals has been the subject of numerous studies, less is known about their recently developed refractory-based counterparts. Here we report on the mechanical properties, deformation mechanisms and topological changes of nanoporous tantalum, a prototypical refractory metal, by means of atomistic simulations of compression tests. An open-source multi-cpu and gpu-capable software is presented and used for the generation of computational samples. The stress strain curves show a non-linear elastic response, with early yielding. The plastic regime is first characterized by a linear hardening followed by an exponential hardening at large strains, associated with a high degree of densification. Plasticity is dominated by dislocation activity, with twinning and vacancy formation appearing as complementary deformation mechanisms. In order to study the mechanical response from a topological perspective, we track the evolution of the genus throughout the tests, finding direct correlations with each regime of the stress strain curves. The results are in agreement with previous studies of plasticity in nanoporous metals and highlight the importance of using topological metrics, for gaining insights into complex aspects of the deformation of nanoporous metals.
A parallel and streaming Dynamic Mode Decomposition algorithm with finite precision error analysis for large data

description: A novel technique based on the Full Orthogonalization Arnoldi (FOA) is proposed to perform Dynamic Mode Decomposition (DMD) for a sequence of snapshots. A modification to FOA is presented for situations where the matrix $A$ is unknown, but the set of vectors $\{A^{i-1}v_1\}_{i=1}^{N-1}$ are known. The modified FOA is the kernel for the proposed projected DMD algorithm termed, FOA based DMD. The proposed algorithm to compute DMD modes and eigenvalues i) does not require Singular Value Decomposition (SVD) for snapshot matrices $X$ with $κ_2(X) \ll 1/ε_m$, where $κ_2(X)$ is the 2-norm condition number of the snapshot matrix and $ε_m$ is the relative round-off error or machine epsilon, ii) has an optional rank truncation step motivated by round off error analysis for snapshot matrices $X$ with $κ_2(X) \approx 1/ε_m$, iii) requires only one snapshot at a time, thus making it a 'streaming' method even with the optional rank truncation step, iv) consumes less memory and requires less floating point operations to obtain the projected matrix than existing projected DMD methods and v) lends itself to easy parallelism as the main computational kernel involves only vector additions, dot products and matrix vector products. The new technique is therefore well-suited for DMD of large datasets on parallel computing platforms. We show both theoretically and using numerical examples that for FOA based DMD without rank truncation, the finite precision error in the computed projection of the linear mapping is $O(ε_mκ_2(X))$. The proposed method is also compared to existing projected DMD methods for computational cost, memory consumption and relative round off error. Error indicators are presented that are useful to decide when to stop acquiring new snapshots. The proposed method is applied to several examples of numerical simulations of fluid flow.

The enterohaemorrhagic escherichia coli effector EspW triggers actin remodelling in a Rac1 dependent manner
Creators: name: Sandu, Pamela
Publisher: name: Imperial College London
Year: 2017

description: Enterohaemorrhagic Escherichia coli (EHEC) is a diarrheagenic pathogen that colonizes the gut mucosa by forming attaching-and-effacing lesions. EHEC employs a type III secretion system (T3SS) to translocate 50 effector proteins that hijack and manipulate host cell signalling pathways, which contribute to subversion of immune responses, colonization and disease. The role of many effectors during infection remains unclear. This study aimed to identify the function of the T3SS effector protein EspW. Although EspW is an EHEC effector, we found that it is present in the prototypes strains EPEC E11 and B171. Furthermore, screening a collection of clinical EPEC isolates revealed that espW is present in 52% of the tested stains, suggesting that EspW is an important virulence factor. We report that EspW modulates actin dynamics in a Rac1-dependant manner. Ectopic expression of EspW results in formation of unique membrane protrusions. Infection of Swiss cells with an EHEC espW deletion mutant induces cell shrinkage that could be overcomed by Rac1 activation via expression of the bacterial GEF, EspT. EspW contains a QLSI motif, similar to the QxSI sequence found in the catalytic loops of the effectors EspM and Map, which activate RhoA and Rac-1, respectively. We found that I237 within that motif is essential for the activity of EspW during ectopic expression and infection. Furthermore, using a yeast two hybrid screen we identified the motor protein Kif15 as a potential interacting partner of EspW. Kif15 and EspW co-localized in co-transfected cells, while ectopically expressed Kif15 localized to the actin pedestals following EHEC infection. The data suggest that Kif15 recruits EspW to the site of bacterial attachment, which in turn activates Rac1, resulting in modifications of the actin cytoskeleton that are essential to maintain cell shape during infection.

description: The Dzyaloshinskii-Moriya (DM) interaction is an antisymmetric exchange interaction that is responsible for the emergence of chiral magnetism. The origin of the DM interaction, however, remains to be identified albeit the large number of studies reported on related effects. It has been recently suggested that the DM interaction is equivalent to an equilibrium spin current density originating from spin-orbit coupling, an effect referred to as the spin Doppler effect. The model predicts that the DM interaction can be controlled by spin current injected externally. Here we show that the DM exchange constant ($D$) in W/CoFeB based heterostructures can be modulated with external current passed along the film plane. At higher current, $D$ decreases with increasing current, which we infer is partly due to the adiabatic spin transfer torque. At lower current, $D$ increases linearly with current regardless of the polarity of current flow. The rate of increase in $D$ with the current density agrees with that predicted by the model based on the spin Doppler effect. These results imply that the DM interaction at the HM/FM interface partly originates from an equilibrium interface spin (polarized) current which can be modulated externally.

description: We present the results of a monitoring campaign aimed at deriving rotation periods for a representative sample of stars in the young (30 Myr) open cluster IC 2602. Rotation periods were derived for 29 of 33 stars monitored. The periods derived range from 0.2d (one of the shortest known rotation periods of any single open cluster star) to about 10d (which is almost twice as long as the longest period previously known for a cluster of this age). We are able to confirm 8 previously known periods and derive 21 new ones, delineating the long period end of the distribution. Despite our sensitivity to longer periods, we do not detect any variables with periods longer than about 10d. The combination of these data with those for IC 2391, an almost identical cluster, leads to the following conclusions: 1) The fast rotators in a 30 Myr cluster are distributed across the entire 0.5 < B-V < 1.6 color range. 2) 6 stars in our sample are slow rotators, with periods longer than 6d. 3) The amplitude of variability depends on both the color and the period. The dependence on the latter might be important in understanding the selection effects in the currently available rotation period database and in planning future observations. 4) The interpretation of these data in terms of theoretical models of rotating stars suggests both that disk-interaction is the norm rather than the exception in young stars and that disk-locking times range from zero to a few Myr.

description: 3-Cyano thiophene-centred π-conjugated mesogens with alkoxy phenyl/biphenyl rings are synthesised by palladium acetate-catalysed direct arylation to investigate the mesophase properties and the molecular order. The synthesised mesogens mostly exhibit smectic A mesophase as confirmed by X-ray diffraction studies. Further, due to the manifestation of π-conjugated core, the mesogens exhibit photo luminescence in solution with emission maxima in the range 425–460 nm. Density functional theory and time-dependent density functional theory calculations of a representative mesogen indicate possible intramolecular charge transfer transition between the biphenyl to 3-cyanothiophene units. Despite structural simplicity, the observation of smectic A phase is attributed to location of strong dipole moment component perpendicular to the long axis of the molecules due to the presence of polar cyano group at 3-position of central thiophene ring. The 13C NMR studies are performed in mesophase and using the 13C–1H dipolar couplings determined from 2D separated local field experiment; the order parameters of central thiophene ring and side arm phenyl rings are calculated. Moreover, the order parameter ratios of thiophene and side arm phenyl rings indicate the bent–core nature of the mesogen.
Systems analysis of transport decarbonisation options

description: The UK committed to reduce their greenhouse gas emissions in the year 2050 by 80% or less of the 1990 levels. Passenger vehicles alone accounted for 14% of the total GHG emissions in the UK in the year 2015 (GOV.UK 2015). The aim of this thesis is to investigate the best future scenario and optimal mix of fuels and vehicles to help achieve this commitment. Two linear programming optimisation models were built to map the future mobility pattern of the passenger transport system and investigate the effect of the different parameters and travel behaviours on the cost and emissions of this sector through scenario-based modelling. The first model describes the behaviour of the passenger transport system with a minimisation objective function of the total cost of fuels and vehicles. Multiple scenarios are investigated by changing the model parameters or constraints to explore their potential in reducing emissions. This model allocates vehicles to trips based on the efficiency of the vehicle when running a certain trip type (driving cycle). It was concluded that trips sharing resulted in the highest CO2 emissions reductions and highest CO2 abatement savings at 1.83 GBP/kg CO2 reduced at year 2050 in reference to the model’s base scenario. The second model, modifies the previous one by allocating the trips to different rural-urban area profiles. This model investigates the effect of transitioning from the current consumer model where each vehicle is owned and used for all trips types to a full shared ownership system where vehicles are shared between drivers and used with the most efficient trip type. It was concluded that reducing CO2 emission from the shared ownership system resulted in cost savings of 0.9 GBP/kg CO2 reduced in reference to the current ownership model. As a result, both vehicles and trips sharing are recommended for future CO2 reductions at low costs.

description: We analyze the dependence of circumstellar extinction on core mass for the brightest planetary nebulae (PNe) in the Magellanic Clouds and M31. We show that in all three galaxies, a statistically significant correlation exists between the two quantities, such that high core mass objects have greater extinction. We model this behavior, and show that the relation is a simple consequence of the greater mass loss and faster evolution times of high mass stars. The relation is important because it provides a natural explanation for the invariance of the [O III] 5007 planetary nebula luminosity function (PNLF) with population age: bright Population I PNe are extinguished below the cutoff of the PNLF. It also explains the counter-intuitive observation that intrinsically luminous Population I PNe often appear fainter than PNe from older, low-mass progenitors.

description: Soil nematodes are involved in nutrient cycles through feeding on microorganisms, and the extent of their functioning is affected by subtle environmental changes and by biological interactions. Considering these features, soil nematodes can serve as bio-indicators reflecting environmental changes in a given ecosystem. However, the mechanism of shaping community structures of nematodes is not well understood due to the complex biological interactions in forest ecosystems. The aim of this study was to clarify the nematode communities and their determinant factors in both coastal and inland Pinus thunbergii forests of central Japan under contrasting environmental conditions. For this purpose, nematodes retrieved from soil samples were morphologically identified at generic levels and discriminated into trophic groups. We also determined whether nematode community structures varied with coastal or inland locations based on non-metric multidimensional scaling. Our results showed that generic richness of nematode at inland habitats (16.2 ± 0.7, mean ± SE) was significantly greater than that at coastal habitats (12.4 ± 0.4). Moreover, the non-metric multidimensional scaling scatter-plot showed nematode communities clustered significantly within their respective coastal and inland habitats. These clusterings were further significantly influenced by surrounding environmental factors; soil water content, soil temperature, litter layer thickness, pH, total both N and C concentrations and C:N ratio. For characteristic trophic groups, microbial-feeding nematodes were represented in coastal forests while predaceous ones were dominated in inland forests. Our study provided fundamental knowledge on the formation of nematode community structures that were shaped by environmental filtering.

description: Two-dimensional electron dispersions with peculiar band crossings provide a platform for realizing topological phases of matter. Here we theoretically show that the $e_g$-orbital manifold of honeycomb-layered transition metal compounds accommodates a plethora of peculiar band crossings, such as multiple Dirac point nodes, quadratic band crossings, and line nodes. From the tight-binding analysis, we find that the band topology is systematically changed by the orbital dependent transfer integrals on the honeycomb network of edge-sharing octahedra, which can be modulated by distortions of the octahedra as well as chemical substitutions. The band crossings are gapped out by the spin-orbit coupling, which brings about a variety of topological phases distinguished by the spin Chern numbers. The results provide a comprehensive understanding of the previous studies on various honeycomb compounds. We also propose another candidate materials by ab initio calculations.

description: We study the partition function of the matrix model of finite size that realizes the irregular conformal block for the case of the ${\cal N}=2$ supersymmetric $SU(2)$ gauge theory with $N_f =2$. This model has been obtained in [arXiv:1008.1861 [hep-th]] as the massive scaling limit of the $β$ deformed matrix model representing the conformal block. We point out that the model for the case of $β=1$ can be recast into a unitary matrix model with log potential and show that it is exhibited as a discrete Painlevé system by the method of orthogonal polynomials. We derive the Painlevé II equation, taking the double scaling limit in the vicinity of the critical point which is the Argyres-Douglas type point of the corresponding spectral curve. By the $0$d-$4$d dictionary, we obtain the time variable and the parameter of the double scaled theory respectively from the sum and the difference of the two mass parameters scaled to their critical values.

description: The evolution of the multipolar structure of the magnetic field of isolated neutron stars is studied assuming the currents to be confined to the crust. We find that except for multipoles of very high order ($l\gsim 25$) the evolution is similar to that of a dipole. Therefore no significant evolution is expected in pulse shape of isolated radio pulsars due to the evolution of the multipole structure of the magnetic field.

description: Gravitational lenses can provide crucial information on the geometry of the Universe, on the cosmological scenario of formation of its structures as well as on the history of its components with look-back time. In this review, I focus on the most recent results obtained during the last five years from the analysis of the weak lensing regime. The interest of weak lensing as a probe of dark matter and the for study of the coupling between light and mass on scales of clusters of galaxies, large scale structures and galaxies is discussed first. Then I present the impact of weak lensing for the study of distant galaxies and of the population of lensed sources as function of redshift. Finally, I discuss the potential interest of weak lensing to constrain the cosmological parameters, either from pure geometrical effects observed in peculiar lenses, or from the coupling of weak lensing with the CMB.

Clustering time series data by analysing graphical models of connectivity and the application to diagnosis of brain disorders
Creators: name: Wolstenholme, Robert
Publisher: name: Imperial College London
Year: 2016

description: In this thesis we investigate clustering and classification techniques applied to time series data from multivariate stochastic processes. In particular we focus on extracting features in the form of graphical models of conditional dependence between the process components. The motivation is to use the techniques on brain EEG data measured from multiple patients and investigate whether it can be used in areas such as medical diagnosis. We look at both the case where the graphical model is estimated based on time series recorded on the scalp and also where the graphical model is estimated based on source signals within the brain. In the first case we use a multiple hypothesis testing approach to build the graphical models and a learning algorithm based on random forests to find patterns within multiple graphical models. In the second case we use independent component analysis (ICA) to extract the source time series and estimate the conditional dependence graphs using partial mutual information. It is of particular note that in this case due to the indeterminacy issues associated with ICA we only know the conditional dependence graphs up to some unknown permutation of the nodes. To solve this issue we use novel methods based on an extension of graph matching to multiple inputs in order to develop a new clustering algorithm. Finally, we show how this algorithm can be combined with further information obtained during the ICA phase contained in columns of the unmixing matrix, to create a more powerful method.
Orbital diameters of primitive permutation groups

description: Let G be a transitive permutation group acting on a finite set X. Recall that G is primitive if there are no non-trivial equivalence relations on X which are preserved by G. An orbital graph of G is a graph with vertex set X and edges {x,y}, where (x,y) belongs to a fixed orbit of the natural action of G on the set X x X. A well-known result by D.G. Higman asserts that G is primitive if and only if all the orbital graphs are connected. For a primitive group G, we define the orbital diameter of G to be the maximum of the diameters of all orbital graphs of G. Let C be an infinite class of finite primitive permutation groups. This gives rise to an infinite family of orbital graphs. It may be that the diameters of these orbital graphs tend to infinity. More interestingly, it may be that the diameters of all the orbital graphs are bounded above by some fixed constant; if this is the case, then we say that C is bounded. Previous results by M. W. Liebeck, D. Macpherson and K. Tent focus attention on classes of almost simple primitive permutation groups which are bounded. In the thesis we analyse the orbital diameters of three families of groups, as follows. Firstly, we analyse the alternating and symmetric groups. For the primitive actions of these groups, we give necessary numerical conditions for the orbital diameter to be bounded above by some constant c and we make the result precise for c=5. For each primitive action, we also describe either all or an infinite family of orbital graphs of diameter 2. Then we analyse the almost simple groups with socle isomorphic to the projective special linear group PSL(2,q). For the primitive actions of these groups we give necessary conditions for the orbital diameter to be bounded above by 2 and we also give information about orbital graphs of diameter 2. Lastly, we analyse a large family of simple groups known as the simple groups of Lie type which consist of the simple classical groups and exceptional groups. In particular, we analyse a class of primitive actions known as parabolic actions, giving a precise description of the actions for which the orbital diameter is at most 2. For the simple classical groups, we also describe infinite families of orbital graphs of diameter 2.
Unparticle may be a Remedy to the Information Loss in the Scattering of Fermion off Dilaton Black-hole

description: We study s-wave scattering of fermion off dilaton black-hole. With one loop correction it was found to suffer from nonpreservation of information and that of course, went against Hawking's revised suggestion on this issue. A nonstandard approach, e.g. the probable existence of unparticle in $(1+1)$ dimension has been adopted here that shows a remedy to get rid of the danger of information loss to bring it in agrees with the Hawking's revised suggestion.

Stellar Populations and Ages of M82 Super Star Clusters

description: We present high signal-to-noise optical spectra of two luminous super star clusters in the starburst galaxy M82. The data for cluster F and the nearby, highly reddened cluster L were obtained with the William Herschel Telescope (WHT) at a resolution of 1.6A. The blue spectrum (3250-5540A) of cluster F shows features typical of mid-B stars. The red spectra (5730-8790A) of clusters F and L show the Ca II triplet and numerous F and G-type absorption features. Strong Ca II and Na I interstellar absorption lines arising in M82 are also detected, and the 6283A diffuse interstellar band appears to be present. The quality of the WHT spectra allows us to considerably improve previous age estimates for cluster F. By comparing the blue spectrum with theoretical model cluster spectra using the PEGASE spectral synthesis code (Fioc & Rocca-Volmerange 1997), we derive an age of 60+/-20 Myr. The strength of the Ca II triplet is also in accord with this age. Cluster L appears to have a similar age, although this is much less certain. The measured radial velocities for the two clusters differ substantially, indicating that they are located in different regions of the M82 disk. Cluster F appears to be deep in M82, slightly beyond the main starburst region while the highly obscured cluster L lies near the outer edges of the disk. We derive an absolute V magnitude of -16.5 for F indicating that it is an extremely massive cluster. The presence of such a luminous super star cluster suggests that the M82 starburst experienced an episode of intense star formation approximately 60 Myr ago.

description: High Mach number shocks are ubiquitous in interstellar turbulence. The Pencil Code is particularly well suited to the study of magnetohydrodynamics in weakly compressible turbulence and the numerical investigation of dynamos because of its high-order advection and time evolution algorithms. However, the high-order algorithms and lack of Riemann solver to follow shocks make it less well suited to handling high Mach number shocks, such as those produced by supernovae (SNe). Here, we outline methods required to enable the code to efficiently and accurately model SNe, using parameters that allow stable simulation of SN-driven turbulence, in order to construct a physically realistic galactic dynamo model. These include the resolution of shocks with artificial viscosity, thermal conductivity, and mass diffusion; the correction of the mass diffusion terms; and a novel generalization of the Courant condition to include all source terms in the momentum and energy equations. We test our methods with the numerical solution of the one-dimensional (1D) Riemann shock tube (Sod, J. Comput. Phys. 1978, 27), also extended to a 1D adiabatic shock with parameters and Mach number relevant to SN shock evolution, including shocks with radiative losses. We extend our test with the three-dimensional (3D) numerical simulation of individual SN remnant evolution for a range of ambient gas densities typical of the interstellar medium and compare these to the analytical solutions of Sedov-Taylor (adiabatic) and the snowplough and Cioffi, McKee and Bertschinger (Astrophys. J. 1988, 334) results incorporating cooling and heating processes. We show that our new timestep algorithm leads to linear rather than quadratic resolution dependence as the strength of the artificial viscosity varies, because of the corresponding change in the strength of interzone gradients.
