description: Massive black holes often exist within dwarf galaxies, and both simulations and observations have shown that a substantial fraction of these may be off-center with respect to their hosts. We trace the evolution of off-center massive black holes (MBHs) in dwarf galaxies using cosmological hydrodynamical simulations, and show that the reason for off-center locations is mainly due to galaxy-galaxy mergers. We calculate dynamical timescales and show that off-center MBHs are unlikely to sink to their galaxys' centers within a Hubble time, due to the shape of the hosts' potential wells and low stellar densities. These wandering MBHs are unlikely to be detected electromagnetically, nor is there a measurable dynamical effect on the galaxy's stellar population. We conclude that off-center MBHs may be common in dwarfs, especially if the mass of the MBH is small or the stellar mass of the host galaxy is large. However detecting them is extremely challenging, because their accretion luminosities are very low and they do not measurably alter the dynamics of their host galaxies.

description: This volume covers Leg 68 (Site 501), Leg 69, and Leg 70 (Site 504) of the cruises of the Drilling Vessel Glomar Challenger. These initial reports present the results of drilling and downhole experiments conducted at Sites 501, 504, and 505, which are on the south flank of the Costa Rica Rift. The sites were drilled during Deep Sea Drilling Project Leg 69 and parts of Legs 68 and 70 between July and December of 1979. The purpose of the drilling was to investigate geothermal phenomena in basaltic basement and overlying sediments at two locations in the same segment of an oceanic spreading center—the Costa Rica Rift. Drilling was only part of the scientific program at the Costa Rica Rift. The chemistry of the interstitial waters was extensively investigated to evaluate reactions within the sediments and the influence of the formation of secondary minerals in the basement. The drilling program that is the focus of this volume was undertaken to investigate a region of contrasting geothermal and hydrological regimes in relatively young oceanic crust (3.9-5.9 m.y. old). In the northern part of the region numerous outcrops of basement permit the free circulation of seawater through the upper crust, keeping the basement at relatively low temperatures. This type of thermal regime is common along the relatively young flanks of mid-ocean ridges. One hundred kilometers to the south the ocean basement is almost completely covered by a 250- to 300-meter layer of sediment that caps the crust with an impermeable blanket and prevents the direct exchange between bottom water and basement pore water. Here, all of the heat from the cooling lithosphere must flow conductively through the sediment. The level of flux is about 200 mW/m2, which results in a temperature drop of 50 to 60°C across the sedimentary layer. The relatively high temperatures in the crust promote the alteration of the igneous basaltic rocks and the cementation of fractures. This type of thermal regime, which is found where high sedimentation rates lead to the fast burial of basement topography, is rare. One of the major objectives of the program was to drill into basement in a young high temperature crust.

description: The aim of this master thesis is the presentation of Nikolaos Mandouvalo’s article “Spectral theory and Eisenstein series for Kleinian groups” (Proc. London Math. Soc. (3) 57 (1988), 209-238), which together with other articles of the same writer is an extension of Selberg’s theory in the case of discrete groups with infinite volume, as well as previous works of Roelcke, Elstrodt and Patterson on the spectral theory and Eisenstein series for Fuchsian groups of the second kind. In this master thesis we have developed the spectral theory for Kleinian groups of the 3-dimensional hyperbolic space, by using Eisenstein series and finally we have proved the analytic continuation of these series and the corresponding scattering operator to the whole complex plane. First, the study is done for a Kleinian group with exponent of convergence less than one, while in the last section we have outlined the way one can study the corresponding problem for a Kleinian group with exponent of convergence greater than or equal to one.
On the role of dissipative effects in the quantum gravitational onset of warm Starobinsky inflation in a closed universe

description: A problematic feature of low energy scale inflationary models, such as Starobinsky inflation, in a spatially closed universe is the occurrence of a recollapse and a big crunch singularity before inflation can even set in. In a recent work it was shown that this problem can be successfully resolved in loop quantum cosmology for a large class of initial conditions due to a non-singular cyclic evolution and a hysteresis-like phenomena. However, for certain highly unfavorable initial conditions the onset of inflation was still difficult to obtain. In this work, we explore the role of dissipative particle production, which is typical in warm inflation scenario, in the above setting. We find that entropy production sourced by such dissipative effects makes hysteresis-like phenomena stronger. As a result, the onset of inflation is quick in general including for highly unfavorable initial conditions where it fails or is significantly delayed in the absence of dissipative effects. We phenomenologically consider three warm inflation scenarios with distinct forms of dissipation coefficient, and from dynamical solutions and phase space portraits find that the phase space of favorable initial conditions turns out to be much larger than in cold inflation.

description: We present a uniform analysis of six examples of embedded wind shock (EWS) O star X-ray sources observed at high resolution with the Chandra grating spectrometers. By modeling both the hot plasma emission and the continuum absorption of the soft X-rays by the cool, partially ionized bulk of the wind we derive the temperature distribution of the shock-heated plasma and the wind mass-loss rate of each star. We find a similar temperature distribution for each star's hot wind plasma, consistent with a power-law differential emission measure, $\frac{d\log EM}{d\log T}$, with a slope a little steeper than -2, up to temperatures of only about $10^7$ K. The wind mass-loss rates, which are derived from the broadband X-ray absorption signatures in the spectra, are consistent with those found from other diagnostics. The most notable conclusion of this study is that wind absorption is a very important effect, especially at longer wavelengths. More than 90 per cent of the X-rays between 18 and 25 Angstrom units produced by shocks in the wind of $ζ$ Puppis are absorbed, for example. It appears that the empirical trend of X-ray hardness with spectral subtype among O stars is primarily an absorption effect.

Drivers underpinning heterogeneity in host-pathogen systems

Publisher: name: Imperial College London

description: The amphibian-infecting chytrid fungi, Batrachochytrium dendrobatidis (Bd) and Batrachochytrium salamandrivorans (Bsal) cause the disease chytridiomycosis and are major agents of global amphibian decline. Despite catastrophic species loss associated with outbreaks of these pathogens, there is within- and between-species heterogeneity in susceptibility to infection, of which our understanding is limited. In this thesis, I investigate the key factors underpinning disease outcome in amphibians. In particular, I focus on the importance of host microbial ecology and whether defensive or synergistic microbe-pathogen relationships shape the host response to infection. In my first data chapter, I show that in wild midwife toad (Alytes obstetricans) populations exhibiting enzootic or epizootic Bd disease dynamics, there is no association between pathogen genetics and epidemiological trends. Meanwhile, I demonstrate strong associations between the host microbiome and disease outcome, with reduced bacterial diversity and differences in community composition in epizootic versus enzootic populations. I further demonstrate that the host skin microbiome differs profoundly based on life stage with larvae and metamorphs exhibiting different bacterial community composition and sharing relatively few microbial taxa. In the following chapter, I begin to disentangle microbe-mediated protection from pathogen-induced disruption of the microbiome by showing that Bsal-induced mortality is associated with microbiome perturbation in two amphibian host species. I further show that transitioning from the wild to captivity results in changes in bacterial and fungal community composition and reduced diversity of the amphibian skin microbiome. In my final chapter, I reveal that skin microbial community structure is linked to mucosal metabolome composition in wild A. obstetricans. In addition, I uncover microbe-metabolite associations linked to population-level disease outcomes. Overall, this thesis exposes some of the key factors driving chytridiomycosis disease dynamics and demonstrates that amphibian skin-associated microbes play an important role in shaping the host response to infection.

Collaborative planning to integrate language and content instruction : a case study
Creators: name: Dempsey, Janet L.
Publisher: name: University of British Columbia
Year: 2009

description: Rapid growth in school ESL populations has led to increased mainstreaming of ESL students in the regular classroom. These students require long term support to be able to reach a level of competence where they can successfully handle academic content. Thus content teachers are required to further expand their role to include taking responsibility for language development as well as content knowledge. However, research has highlighted the lack of positive attitudes on the part of content teachers towards changing instruction for the ESL student. This thesis examines the emerging process of collaborative planning between an ESL Resource teacher and content teachers with the aim of helping the classroom teacher adapt teaching processes for ESL learners in a way which is developmental, contigent and owned by the classroom teacher. A shared frame of reference of the need to integrate language and content instruction was the basis of this collaboration. Data is qualitative and includes observation, document collection and tape recordings made by the researcher who was a participant! observer. The particulars of this developmental process and the contextual factors which affected implementation are presented.

description: Dynamic imaging is a beneficial tool for interventions to assess physiological changes. Nonetheless during dynamic MRI, while achieving a high temporal resolution, the spatial resolution is compromised. To overcome this spatio-temporal trade-off, this research presents a super-resolution (SR) MRI reconstruction with prior knowledge based fine-tuning to maximise spatial information while reducing the required scan-time for dynamic MRIs. An U-Net based network with perceptual loss is trained on a benchmark dataset and fine-tuned using one subject-specific static high resolution MRI as prior knowledge to obtain high resolution dynamic images during the inference stage. 3D dynamic data for three subjects were acquired with different parameters to test the generalisation capabilities of the network. The method was tested for different levels of in-plane undersampling for dynamic MRI. The reconstructed dynamic SR results after fine-tuning showed higher similarity with the high resolution ground-truth, while quantitatively achieving statistically significant improvement. The average SSIM of the lowest resolution experimented during this research (6.25~\% of the k-space) before and after fine-tuning were 0.939 $\pm$ 0.008 and 0.957 $\pm$ 0.006 respectively. This could theoretically result in an acceleration factor of 16, which can potentially be acquired in less than half a second. The proposed approach shows that the super-resolution MRI reconstruction with prior-information can alleviate the spatio-temporal trade-off in dynamic MRI, even for high acceleration factors.
Physical properties of a very diffuse HI structure at high Galactic latitude

description: The main goal of this analysis is to present a new method to estimate the physical properties of diffuse cloud of atomic hydrogen observed at high Galactic latitude. This method, based on a comparison of the observations with fractional Brownian motion simulations, uses the statistical properties of the integrated emission, centroid velocity and line width to constrain the physical properties of the 3D density and velocity fields, as well as the average temperature of HI. We applied this method to interpret 21 cm observations obtained with the Green Bank Telescope of a very diffuse HI cloud at high Galactic latitude located in Firback North 1. We first show that the observations cannot be reproduced solely by highly-turbulent CNM type gas and that there is a significant contribution of thermal broadening to the line width observed. To reproduce the profiles one needs to invoke two components with different average temperature and filling factor. We established that, in this very diffuse part of the ISM, 2/3 of the column density is made of WNM and 1/3 of thermally unstable gas (T ~2600 K). The WNM gas is mildly supersonic (~1) and the unstable phase is definitely sub-sonic (~0.3). The density contrast (i.e., the standard deviation relative to the mean of density distribution) of both components is close to 0.8. The filling factor of the WNM is 10 times higher that of the unstable gas, which has a density structure closer to what would be expected for CNM gas. This field contains a signature of CNM type gas at a very low level (N_H ~ 3 x 10^19) which could have been formed by a convergent flow of WNM gas.

description: Η βιολογία των ελευθέρων ριζών αποτελεί αντικείμενο έντονης ερευνητικής δραστηριότητας επειδή σχετίζεται με διάφορες ασθένειες. Ένας σημαντικός και καλά μελετημένος δείκτης για τον έλεγχο της υπεροξείδωσης των λιπιδίων είναι η μαλονδιαλδεϋδη (MDA), η οποία αποτελεί το κύριο προϊόν της υπεροξείδωσης των πολυακόρεστων λιπαρών οξέων. Αυξημένα επίπεδα της MDA επίσης σχετίζονται με διάφορες ασθένειες, όπως η συμφορητική καρδιακή ανεπάρκεια, η αθηροσκλήρωση μέχρι και τη νόσο του Alzheimer. Η υγρή χρωματογραφία υψηλής πίεσης είναι το ακριβέστερο εργαλείο για την μέτρηση της MDA, εφόσον χρησιμοποιούνται κατάλληλα πρωτόκολλα. Μελετήθηκαν 3 πρωτόκολλα μέτρησης MDA και έγινε μια προσπάθεια εφαρμογής τους σε 10 τυχαία δείγματα πλάσματος. Τα πρωτόκολλα ήταν των Karatas και συν., Mateos και συν. και Pilz kai συν. και επιλέχθηκαν με βάση την ακρίβεια και την ευκολία στην εφαρμογή τους. Η MDA μετρήθηκε με επιτυχία μόνο με το πρωτόκολλο των MATEOS και συν. μετά από διάφορες τροποποιήσεις. Η intra-assay διακύμανση και η inter-assay διακύμανση επιβεβαίωσαν την ορθότητα των αποτελεσμάτων. Η εφαρμογή ενός πρωτοκόλλου μέτρησης MDA με υγρή χρωματογραφία υψηλής πίεσης δεν είναι απλή διαδικασία και απαιτεί πολλές δοκιμές και πειραματισμούς. Στο τέλος όλης της διαδικασίας είχαμε ένα εργαλείο μέτρησης ακριβές και εύχρηστο έτοιμο να χρησιμοποιηθεί για περαιτέρω έρευνα
description: Free radical biology is a very important research topic because of their correlation with various deceases. A very well studied and important indicator for the control of lipid peroxidation is MDA, that is the main product of lipid peroxidation. High levels of MDA have been correlated with various deceases. High pressure liquid chromatography is a good measurement tool, based on the protocol you use. We studied 3 protocols of MDA measurement and we tried to apply them in our lab. These protocols were Pilz et. al., Karatas et al and Mateos et al and they were chose because of their accuracy and easy use. MDA was measured only with the protocol of Mateos et al after many modifications. Intra-assay variability and inter-assay variability confirmed our results. To apply a MDA measurement protocol isn’t a simple task and requires many experimentations. We established a measurement tool that is accurate and easy to use for research.

description: We show that the functional analogue of QMA$\cap$coQMA, denoted F(QMA$\cap$coQMA), equals the complexity class Total Functional QMA (TFQMA). To prove this we need to introduce alternative definitions of QMA$\cap$coQMA in terms of a single quantum verification procedure. We show that if TFQMA equals the functional analogue of BQP (FBQP), then QMA$\cap$coQMA = BQP. We show that if there is a QMA complete problem that (robustly) reduces to a problem in TFQMA, then QMA$\cap$coQMA = QMA. These results provide strong evidence that the inclusions FBQP$\subseteq$TFQMA$\subseteq$FQMA are strict, since otherwise the corresponding inclusions in BQP$\subseteq$QMA$\cap$coQMA$\subseteq$QMA would become equalities.

description: Τhe current thesis introduces us briefly to the life and work of Norberto Bobbio, it examines his democratic theory and focuses on the principles and norms of democracy, the obstacles encountered over the centuries, the difficulties and the broken promises. In the last chapter we analyze the future of modern representative democracy in the western states and also the solution proposed by Norberto Bobbio introducing a mixed democratic model based on the convergence of direct and representative democracy that would imagine in the center of the government and political life the citizen as ‘a person’ and not an automatic machine that only obeys. The Italian political philosopher considers as a basic principle and purpose of democracy the creation of a society composed by truly equal and free citizens. And while Bobbio maintains a skeptical and maybe a pessimistic attitude towards the situation in the contemporary democratic states and the quality of representative democracy nowadays, on the same time he never abandons his faith in democracy, as the most ideal constitution of all.

description: This report draws upon two data sets to examine the gender wage gap among member institutions of the Association of Research Libraries (ARL). The first data set consists of 35 years of salary survey data collected by ARL and is used to provide trend data on the gender wage gap from 1980 to 2014 as well as present an in-depth look at the wage gap in 2014. After controlling for variables such as years of experience, position, and type of library in the 2014 ARL Salary Survey data, results revealed that women on average made approximately 2 percent less than their male counterparts in 2014. The second data set comes from a survey of ARL institutions conducted by the researchers in 2015 and is used to explore the influence of additional variables on the gender wage gap that were not found in the ARL Salary Survey data. Results from both data sets suggest a substantial difference between the gender wage gap in ARL institutions and the workforce as a whole.

description: A scaling theory of replica symmetry breaking (RSB) in the SK-model is presented in the framework of critical phenomena for the scaling regime of small inverse RSB-orders, small temperatures, small magnetic fields, and near opposite pseudo-dynamic limits. We employ the pseudo-dynamical picture (PRL98, 127201 (2007)) with two critical points, where separated temperature- and magnetic field-scaling is obtained. An unconventional scaling hypothesis for the free energy is given, modeling this separated scaling in accordance with detailed numerical self-consistent solutions for up to 200 orders of RSB. A divergent correlation-length describes the RSB-criticality as a long-range correlation effect occurring on the pseudo-lattice of RSB-orders. Rational-valued exponents are concluded with high precision from high-order RSB scaling and by using a new fixed point extrapolation method. Power laws, scaling relations, and scaling functions are analyzed.
A short history of the Canadian Players, 1954-1966

description: A brief history of the Canadian Players, a theatre company which toured across Canada and the United States from 1954 -1966. The company played in cities and university centres and in small towns and communities from Moosonee and Flin Ron in the North to the southern United States and from Newfoundland and the New England States to Vancouver Island and southern California. The nucleus of the Canadian Players came from the Stratford Shakespearean Festival. Robin Patterson and Laurel Crosby crossed the continent as agents of the company, interesting influential citizens in sponsoring a theatrical company performing the plays of Shaw and Shakespeare. From a small company of eight actors performing Saint Joan on a bare stage the company grew to two casts and crews of up to twenty members, who spent eight months annually travelling by bus to perform across the length and breadth of the continent. The information about the Canadian Players was obtained from letters, chiefly those from Robin Patterson to Tom Pattterson, from newspaper reviews and reports in the press,which are gathered together in several scrap books, vertical files and micro-fiche in the Theatre Department of the Toronto reference Libr ary and from conversations with some of the surviving members of the company. Most of these conversations have been recorded on tape. Other information was gathered from transcripts from taped interviews which were supplied by Robin Patterson. I was also privileged to be permitted the use of manuscript material of Florence Pelton Patterson, the first secretary, and that of Tony Van Bridge, an actor and director for several years. The contribution made to Canadian theatre by the Canadian Players in their taking drama to every part of the country and their involvement of local communities in developing an audience for the regional and other theatres which followed them is discussed.

description: Abstract:  This is descriptive and exploratory research.  Our focus is first, to build on earlier work by presenting a previously undocumented vocalization and accompanying behavior/context which most resemble the expression of the enjoyment of companionship in a Great Horned Owl (Bubo virginianus).  Second, we draw attention to the only other source attributing companionship to virginianus.  Those vocalizations are described qualitatively.  We describe putatively similar vocalizations qualitatively and quantitatively from the data of 352 vocalizations we collected and examine their significance as another expression of enjoyment of companionship.  We then place our findings in perspective.

description: The origin of Galactic cosmic rays (with energies up to 10^15 eV) remains unclear, though it is widely believed that they originate in the shock waves of expanding supernova remnants. Currently the best way to investigate their acceleration and propagation is by observing the gamma-rays produced when cosmic rays interact with interstellar gas. Here we report observations of an extended region of very high energy (VHE, >100 GeV) gamma-ray emission correlated spatially with a complex of giant molecular clouds in the central 200 pc of the Milky Way. The hardness of the gamma-ray spectrum and the conditions in those molecular clouds indicate that the cosmic rays giving rise to the gamma-rays are likely to be protons and nuclei rather than electrons. The energy associated with the cosmic rays could have come from a single supernova explosion around 10,000 years ago.

description: The goal of medical imaging is to acquire and display images of human anatomy and function such that they can be optimally interpreted by a trained observer, e.g., a radiologist. Start-of-art medical image quality is measured by the performance of an observer on a given clinical task. Since psychophysical studies are resource intensive, model observers are widely used as a surrogate in task-based assessment of image quality. Model observers are typically designed to detect at most one abnormality, e.g., a single lesion. However, in clinical practice, there may be multiple abnormalities in a single set of images, which can have a significant impact on treatment planning and outcomes. For example, patients with multifocal and multicentric breast cancer (MFMC), i.e., the presence of two or more tumor foci within the same breast, are more likely to undergo mastectomy rather than breast conservation therapy. Detecting multiple breast tumors is challenging because the prevalence of tumors varies significantly across breast regions, and radiologists do not know the number or location of tumors a priori. The vision of this dissertation is that digital breast tomosynthesis (DBT) has the potential to improve the detection of MFMC, and may offer advantages such as fewer false-positive findings, lower cost, and better accessibility. This dissertation focuses on the design and applications of a model observer to optimize DBT system geometries for detection of multiple breast tumors. This is significant and innovative because prior efforts to optimize DBT image quality only considered unifocal breast cancer scenarios. We highlight the following two main aspects of contributions in this dissertation: (1) We have developed a novel model observer that detects multiple abnormalities in anatomical backgrounds. (2) We have employed the extended 3D multi-lesion model observer to identify DBT system geometries that are most effective for the detection of MFMC. Our results demonstrate that the presence of more than one tumor present distinct challenges to DBT optimization, and that DBT geometries that yield images that are informative for the task of detecting unifocal breast cancer may not necessarily be informative for the task of detecting MFMC. We are validating the clinical relevance of our model observer studies with an ongoing human observer study with experienced breast imaging radiologists.

description: Σκοπός της διατριβής ήταν να μελετήσουμε ποιες κατηγορίες εργαζομένων υπάγονται υποχρεωτικά στην ασφάλιση του ΙΚΑ-ΕΤΑΜ. Η υποχρεωτικότητα της ασφάλισης στο ΙΚΑ-ΕΤΑΜ συνδέεται από το νόμο και τη νομολογία των δικαστηρίων με την έννοια της εξαρτημένης εργασίας, καθώς η τελευταία αποτελεί απαραίτητη προϋπόθεση για την υπαγωγή στην ασφάλιση του ΙΚΑ-ΕΤΑΜ. Αρχικά παρουσιάσαμε τις προϋποθέσεις υπαγωγής στην ασφάλιση του εν λόγω Ταμείου. Εν συνεχεία εξετάσαμε τη διάκριση των εννοιών της εξαρτημένης και ανεξάρτητης εργασίας, καθώς και ποια στοιχεία τις διαφοροποιούν. Επιπροσθέτως αναφερθήκαμε στη νομολογιακή κατασκευή της εξαρτημένης εργασίας σε μία εργασιακή σχέση με βάση μία δέσμη κριτηρίων που εξετάζονται ενδεικτικά τόσο από τα πολιτικά όσο και από τα διοικητικά δικαστήρια. Επιπλέον ασχοληθήκαμε με την διεύρυνση της έννοιας της εξάρτησης με νομοθετικές παρεμβάσεις και αναφερθήκαμε αναλυτικά σε τέτοιες περιπτώσεις νομοθετικής εξομοίωσης με την έννοια της εξαρτημένης εργασίας. Τέλος ερευνήσαμε το νόμιμο τεκμήριο υπαγωγής στην ασφάλιση του ΙΚΑ-ΕΤΑΜ του άρθρου 2 του ΑΝ 1846/1951, καθώς και το νόμιμο τεκμήριο εξαρτημένης εργασίας του άρθρου 1 του ν. 3846/2010.
description: The aim of the present thesis was to study which categories of workers mandatorily fall within the IKA-ETAM insurance. The mandatory character of the IKA-ETAM insurance is linked by statute and case law with the concept of the dependent work, since the later constitutes an essential requirement for the falling within the IKA-ETAM insurance. Firstly we examined the requirements for the falling within the IKA-ETAM insurance and following that we examined the distinction between dependent and independent work, as well as which elements differentiate them. Additionally, we discussed the construction by the courts of the dependent work within a work relationship on the basis of a set of criteria indicatively examined both by the civil as well as the administrative courts. Moreover we focused on the expansion of the concept of the dependence by statutory intervention and elaborated on such cases of statutory assimilation to the concept of dependent work. Finally, we analyzed the lawful presumption of falling within the IKA-ETAM insurance of section 2 of compulsory law 1846/1951, as well as the lawful presumption of dependent work of section 1 of law 3846/2010.

description: One of the most important aims of grain boundary modeling is to predict the evolution of a large collection of grains in phenomena such as abnormal grain growth, coupled grain boundary motion, and recrystallization that occur under extreme thermomechanical loads. A unified framework to study the coevolution of grain boundaries with bulk plasticity has recently been developed by Admal et al. (2018), which is based on modeling grain boundaries as continuum dislocations governed by an energy based on the Kobayashi--Warren--Carter (KWC) model (Kobayashi et al., 1998, 2000). While the resulting unified model demonstrates coupled grain boundary motion and polygonization (seen in recrystallization), it is restricted to grain boundary energies of the Read--Shockley type, which applies only to small misorientation angles. In addition, the implementation of the unified model using finite elements inherits the computational challenges of the KWC model that originate from the singular diffusive nature of its governing equations. The main goal of this study is to generalize the KWC functional to grain boundary energies beyond the Read--Shockley-type that respect the bicrystallography of grain boundaries. The computational challenges of the KWC model are addressed by developing a thresholding method that relies on a primal dual algorithm and the fast marching method, resulting in an O(NlogN) algorithm, where N is the number of grid points. We validate the model by demonstrating the Herring angle relation, followed by a study of the grain microstructure evolution in a two-dimensional face-centered cubic copper polycrystal with crystal symmetry-invariant grain boundary energy data obtained from the lattice matching method of Runnels et al. (2016a,b).
On the modified KKLT procedure: a case study for the P_{11169}[18] model

description: We probe the existence of supersymmetric vacua of the type IIB orientifold of the elliptic Calabi-Yau space P_{11169}[18] where generically two complex structure moduli z_i, the dilaton tau and the two Kähler moduli T_i are stabilized by fluxes and gaugino condensates. The usual KKLT procedure, which integrates out the complex structure moduli and the dilaton, actually has to be modified, such that one keeps the dependence on tau. We derive explicitely the resulting effective superpotential W_{eff}(tau) for the dilaton for various flux combinations. As this is actually a non-holomorphic quantity one must properly work with the G-function. The remaining SUSY equations for tau and the T_i can be resolved explicitely.
