Proving Well-Definedness of JML Specifications with KeY
Creators: name: Kirsten, Michael
Publisher: name: Karlsruhe
Year: 2013

description: Specification methods in formal program verification enable the enhancement of source code with formal annotations as to formally specify the behaviour of a program. This is a popular way in order to subsequently prove software to be
reliable and meet certain requirements, which is crucial for many applications and gains even more importance in modern society. The annotations can be taken as a contract, which then can be verified guaranteeing the specified program element – as a receiver – to fulfil this contract with its caller. However, these functional contracts can be problematic for partial functions, e.g., a division, as certain cases may be undefined, as in this example a division by zero. Modern programming languages such as Java handle undefined behaviour by casting an exception. There are several approaches to handle a potential undefinedness of specifications. In this thesis, we chose one which automatically generates formal proof obligations ensuring that undefined specification expressions will not be evaluated. Within this work, we elaborate on so-called Well-Definedness Checks dealing with undefinedness occurring in specifications of the modelling language JML/JML* in the KeY System, which is a formal software development tool providing mechanisms to deductively prove the before mentioned contracts. Advantages and delimitations are discussed and, furthermore, precise definitions as well as a fully functional implementation within KeY are given. Our work covers the major part of the specification elements currently supported by KeY, on the higher level including class invariants, model fields, method contracts, loop statements and block contracts. The process of checking the
well-definedness of a specification forms a preliminary step before the actual proof and rejects undefined specifications. We further contribute by giving a choice between two different semantics, both bearing different
advantages and disadvantages. The thesis also includes an extensive case study analysing many examples and measuring the performance of the implemented Well-Definedness Checks.

description: For nanoscale CMOS applications, strained-silicon devices have been receiving considerable attention owing to their potential for achieving higher performance and compatibility with conventional silicon processing. In this work, an analytical model for the output current characteristics (I-V) of nanoscale bulk strained-Si/SiGe MOSFETs, suitable for analog circuit simulation, is developed. We demonstrate significant current enhancement due to strain, even in short channel devices, attributed to the velocity overshoot effect. The accuracy of the results obtained using our analytical model is verified using two-dimensional device simulations.

description: Bulk Bi2Te3 is known to be a topological insulator. We investigate surface states of Bi2Te3(111) thin films using density-functional theory including spin-orbit coupling. We construct a method to unambiguously identify surface states of thin film topological insulators. Applying this method for one to six quintuple layers of Bi2Te3, we find that the topological nature of the surface states remains robust with the film thickness and that the films of three or more quintuple layers have topologically non-trivial or protected surface states, in agreement with recent experiments.

description: Observing the violation of Bell's inequality tells us something about all possible future theories: they must all predict nonlocal correlations. Hence Nature is nonlocal. After an elementary introduction to nonlocality and a brief review of some recent experiments, I argue that Nature's nonlocality together with the existence of free will is incompatible with the many-worlds view of quantum physics.

description: PDFs in the wild offer a bewildering amount of variation in syntax, features and structure. For those building parsers or evaluating parsers, it is critical to have a broad coverage corpus available to assess and discover distributions of issues "in the wild" or on specific client document sets. In this talk, our team will present our work building a File Observatory to support Defense Advanced Research Projects Agency (DARPA)'s SafeDocs program, which has an initial primary focus on PDF and related formats (e.g. jpeg, ICC, fonts, XMP). The talk will focus on a) gathering interesting PDFs and b) making features searchable and patterns easily discoverable with open source search technologies. In the first part, we'll discuss gathering millions of PDFs from Common Crawl and thousands of files from open source PDF parser bug tracker sites. In the second we'll outline the capabilities of the File Observatory to run multiple parsers against the files, extract features (runtime exceptions and error messages as well as structural features, including PDF DOM keys and values and other semantic components within the PDFs' structures) and make those features searchable with Elasticsearch. We will also briefly demonstrate how the observatory enables the discovery of spelling variations (e.g. /Subtype vs. /SubType), and structural features which are statistically correlated with specific creator tools.

description: Predicting the fate of organic compounds in the aquatic environment remains a challenge due to the complexity of natural systems and diverse interactions with surfaces. In this study, the transport behavior of the β-blocker metoprolol (MTP) was studied in water-saturated columns filled with quartz sand (pH 3–11; [NaCl] of 1, 10, and 100 mmol L–1). A significant dependence of MTP retardation on pH and [NaCl] was observed ranging from a 10-fold retardation at pH 6 and 1 mmol L–1 NaCl to virtually none at pH 11. A retardation model was implicated considering (1) the speciation of MTP, (2) the surface reactions of MTPH+, and Na+ with charged surface silanol groups SiO– of quartz, and (3) the protolysis reaction between SiO– and SiOH. Modeling was performed using the complete dataset of 43 retardation values at once (R2 = 0.998). Exemplary predictions were performed for three aquifer settings to illustrate general trends in mobility. This comprehensive approach is an important basis for environmental fate prediction of organic contaminants in the future.

description: A server farm is examined, where a number of servers are used to offer a service to impatient customers. Every completed request generates a certain amount of profit, running servers consume electricity for power and cooling, while waiting customers might leave the system before receiving service if they experience excessive delays. A dynamic allocation policy aiming at satisfying the conflicting goals of maximizing the quality of users' experience while minimizing the cost for the provider is introduced and evaluated. The results of several experiments are described, showing that the proposed scheme performs well under different traffic conditions.

Central American displacement and the politics of United States deterrence strategy
Creators: name: Barrick, Leigh Christine
Publisher: name: University of British Columbia
Year: 2018

description: This dissertation examines the amplification of United States efforts to “deter” the arrival of asylum seekers from El Salvador, Guatemala, and Honduras in recent years. I focus on: (1) the forced separation of asylum-seeking families through detention; (2) the gendering and denial of common Central American asylum claims; and (3) knowledge production that depoliticizes conflict in El Salvador. I ask: how does forced separation impact families’ well-being and access to asylum? What makes this practice politically possible? What obstacles do young men face in making their asylum claims heard? What might more complex stories of displacement sound like, if permitted? I analyze displacement through a coloniality/modernity lens, meaning that I foreground how power inequalities rooted in colonial conquests contribute to uneven mobility in the Americas today. I draw from qualitative research, including interviews with asylum seekers and advocates, textual analysis of court filings and policy documents, and observation of asylum processes. In Chapters 3 and 4, I suggest forced separation harms families by threatening their well-being and access to asylum. I conceptualize this practice as a form of racialized governance. In Chapters 5 and 6, I demonstrate that detention throws countless hurdles into the path of asylum seekers, while adjudication tends to feminize, depoliticize, and thereby reject common Central American claims. I conclude that the political nature of conflict in El Salvador defies such depoliticizing asylum narratives, demanding a more complex analysis. I argue that the amplification of deterrence strategy expands a racialized system of governance over mobility in the Americas. It limits public debate by depoliticizing the causes of displacement from Central America, while distancing United States actors from any culpability. This dissertation contributes to a growing critique of deterrence strategy by elaborating a coloniality/modernity analytical approach to the study of displacement, which creates a fuller picture of the power imbalances that oblige people to leave their communities. The dissertation serves as a counterweight to deterrence strategy – challenging the current politics of mobility in the Americas and providing insights into strategies for change.
On the apparent absence of broad iron lines in Seyfert galaxies

Subjects: subject: Cosmology and Nongalactic Astrophysics (astro-ph.CO)

description: We present an analysis of XMM-Newton observations of eleven Seyfert galaxies that appear to be missing a broad iron K alpha line. These objects represent a challenge to the established paradigm for active galactic nuclei, where a relatively cold accretion disc feeds the central black hole. In that paradigm, X-ray illumination of the accretion disc should lead to continuum and fluorescence emission from iron which is broadened and shifted by relativistic effects close the hole. We extend the work of Nandra et al. (2007), who found no evidence for such a component in an earlier analysis of these objects, by testing a variety of more complex relativistic reflection models. Specifically, we consider the possibility that the disc is highly ionised, and/or that the the reflection is heavily blurred by strong relativistic effects in a Kerr geometry. We find that in 8/11 of the observations with no apparent broad iron line, the fit is significantly improved when an ionised or strongly blurred reflector is included, and that all 11 observations allow for such a component. The disc inclinations are found generally to be around 60 degrees, which when combined with a steep emissivity profile results in strong relativistic blurring of the reflection, rendering the K alpha line difficult to distinguish from the underlying continuum. Nevertheless, relativistic reflection does appear to be present, and the strength of the smeared reflection is similar to that expected from a flat disc illuminated by a point source. Such blurred reflection and the associated steep radial emissivity profiles are consistent with the gravitational light bending of the continuum photons close to the black hole.

Analyzing Maintenance Activities of Software Libraries

Year: 2023

description: Industrial applications heavily integrate open-source software libraries nowadays. Beyond the benefits that libraries bring, they can also impose a real threat in case a library is affected by a vulnerability but its community is not active in creating a fixing release. Therefore, I want to introduce an automatic monitoring approach for industrial applications to identify open-source dependencies that show negative signs regarding their current or future maintenance activities. Since most research in this field is limited due to lack of features, labels, and transitive links, and thus is not applicable in industry, my approach aims to close this gap by capturing the impact of direct and transitive dependencies in terms of their maintenance activities. Automatically monitoring the maintenance activities of dependencies reduces the manual effort of application maintainers and supports application security by continuously having well-maintained dependencies.

A New Strained-Silicon Channel Trench-gate Power MOSFET: Design and Analysis

description: In this paper, we propose a new trench power MOSFET with strained Si channel that provides lower on resistance than the conventional trench MOSFET. Using a 20% Ge mole fraction in the Si1-xGex body with a compositionally graded Si1-xGex buffer in the drift region enables us to create strain in the channel along with graded strain in the accumulation region. As a result, the proposed structure exhibits 40% enhancement in current drivability, 28% reduction in the on-resistance and 72% improvement in peak transconductance at the cost of only 12% reduction in the breakdown voltage when compared to the conventional trench gate MOSFET. Furthermore, the graded strained accumulation region supports the confinement of carriers near the trench sidewalls improving the field distribution in the mesa structure useful for a better damage immunity during inductive switching.

description: A record of morbidity and medical request profiles in international humanitarian aid, taking the earthquake in BAM in Iran in 2003 as an example Objective: With the humanitarian work of the International Red Cross after the earthquake in BAM, Iran, it should be noted that international and national cooperation is possible according to recognised standards and concepts, and therefore morbidity records can be included uniformly in the context of day to day work even in post disaster situations. The data ascertained show changes in the disease spectrum. Basic health provision according to the primary health care concept has priority in the post disaster response (> 6 days) of the earthquake compared to more surgically oriented medical acute aid from abroad. Material and methodology: In the international consensus conference at the beginning of January 2004, uniform morbidity recording was fixed to simple standardised case definitions. The recording of traumatic, infectious and non-infectious diseases was carried out during the routine work in the out-patient facilities of the emergency response units of January 3 to 31, 2004 . Examination was according to the following indicators: Proportional morbidities, sum of the proportional morbidities. Results and discussion: 16677 new cases were included in the complete examination time period. The health facility rate only gradually increased. Temporal fluctuations in the numbers treated may be caused by secondary care of the injured, by a possible lack of accessibility (transport problems) or an increased acceptance of facilities. A written specification of the case definitions was not carried out in BAM, and so a comparison is not possible for recorded morbidities at the same time, and consistency cannot be reached for some of the data. Nine diagnoses/categories cover 98.68% of the consultations in the complete time period. Non-traumatic health problems predominate for the whole of the month. The category "others" is too high with 57.94%. Therefore, it may be assumed that certain diagnoses were overestimated, underestimated or not recognised. Vulnerable groups (children, women, the old), were not completely included. Conclusion: Standards and guidelines for health care in humanitarian aid exist, and are of help during planning, decision finding, execution and communication. Data acquisition instruments (registering books and patient files) should be developed and standardised by national and international humanitarian groups. The recording of morbidity is a simple instrument in the context of out-patient facilities with valuable information for further work during catastrophes.

description: We report the CO(J=1-0) observations of M51 using both the Combined Array for Research in Millimeter Astronomy (CARMA) and the Nobeyama 45m telescope (NRO45). We describe a procedure for the combination of interferometer and single-dish data. In particular, we discuss (1) the joint imaging and deconvolution of heterogeneous data, (2) the weighting scheme based on the root-mean-square (RMS) noise in the maps, (3) the sensitivity and uv-coverage requirements, and (4) the flux recovery of a combined map. We generate visibilities from the single-dish map and calculate the noise of each visibility based on the RMS noise. Our weighting scheme, though it is applied to discrete visibilities in this paper, is applicable to grids in uv-space, and this scheme may advance in future software development. For a realistic amount of observing time, the sensitivities of the NRO45 and CARMA visibility data sets are best matched by using the single dish baselines only up to 4-6 kilo-lambda (about 1/4-1/3 of the dish diameter). The synthesized beam size is determined to conserve the flux between synthesized beam and convolution beam. The superior uv-coverage provided by the combination of CARMA long baseline data with 15 antennas and NRO45 short spacing data results in the high image fidelity, which is evidenced by the excellent overlap between even the faint CO emission and dust lanes in an optical HST image and PAH emission in an Spitzer 8 micron image.

description: We consider a model for the cyclic brightness variations of a young star with a low-mass companion that accretes matter from the remnants of a protostellar cloud. At small inclinations of the binary orbit to the line of sight, the streams of matter and the density waves excited in the circumbinary disk can screen the primary component of the binary from the observer. To study these phenomena, we have computed grids of hydrodynamic models for binary systems by the SPH method based on which we have constructed the phase light curves as a function of the rotation angle of the apsidal line relative to the observer. The model parameters were varied within the following ranges: the component mass ratio q = 0.01-0.1 and the eccentricity e = 0-0.5. We adopted optical grain characteristics typical of circumstellar dust. Our computations have shown that the brightness oscillations with orbital phase can have a complex structure. The amplitudes and shapes of the light curves depend strongly on the inclination of the binary orbit and its orientation relative to the observer and on the accretion rate. The results of our computations are used to analyze the cyclic activity of UX Ori stars.

Improving risk prediction for the malignant transformation of low-grade oral dysplasia - clinicopathological features and loss of heterozygosity
Creators: name: Rock, Leigha Duree
Publisher: name: University of British Columbia
Year: 2018

description: A major barrier to oral cancer prevention is the lack of risk predictors for the malignant progression of oral potentially malignant lesions (OPML). OPML with evidence of dysplasia are at risk of progressing to oral cancer. However, not all will progress and predicting which low- grade dysplasia (LGD; mild/moderate dysplasia) are at risk of progression is challenging. The overall goal of this thesis was to advance risk stratification and to improve the prediction of malignant progression in LGD. Three research projects were developed to accomplish this goal. Each identified important insights into the phenotypic changes associated with malignant transformation and advanced risk prediction by exploring the association between histological, clinical and molecular biomarkers and malignant progression. The first project revealed that dysplasia with or without lichenoid mucositis (LM) had similar cancer risk and that pathologists and clinicians should not discount dysplasia in the presence of LM. The second project compared the clinical and molecular features of LGD in smokers in contrast to those of non-smokers (NS) and confirmed that NS possess an increased risk of progression, and progressed more quickly, than smokers. These findings emphasize the need for clinicians to consider smoking history (or the lack thereof) and molecular profiles in the triage and management of LGD. The final project aimed to advance a risk prediction model using microsatellite analysis for loss of heterozygosity (LOH) and repeated measures of clinicopathological features. Multivariable analysis showed that after LOH risk category, temporal repeated measures of toluidine blue status was the most significant predictor of progression. Two risk prediction models are presented and provide a systematic decision-making process for these very heterogeneous group of lesions. Patients at higher risk could be offered intensified surveillance or targeted interventions based on their predicted risk of disease, while patients at low risk would be spared from excessive screening and treatment. This body of work has advanced the risk stratification of LGD and presents an important framework to give scientists and clinicians a better view into the natural history of the disease and a novel approach to integrate repeated measurements of change over time into risk models.

description: The coastal area of Ierapetra has been vulnerable to the phenomenon of coastal erosion, which in recent decades has caused significant alteration of the coastline of the area. This paper examines the change in the coastline of Ierapetra, which as a result of anthropogenic erosion is inextricably linked to coastal spatial planning failures. The study of the city from a historical and urban point of view creates the basis on which the analysis of aerial photographs of the city and its coastal area is based in order to investigate the changes that have taken place. The work aims to link the changes in the coastal area of the study area with economic development and spatial planning, in order to evaluate the way anthropogenic activities shape coastal zones and the effectiveness of spatial planning for their protection.

description: We utilize detailed time-varying models of the coupled evolution of stars and the HI, H_2, and CO-bright H_2 gas phases in galaxy-sized numerical simulations to explore the evolution of gas-rich and/or metal-poor systems, expected to be numerous in the Early Universe. The inclusion of the CO-bright H_2 gas phase, and the realistic rendering of star formation as an H_2-regulated process (and the new feedback processes that this entails) allows the most realistic tracking of strongly evolving galaxies, and much better comparison with observations. We find that while galaxies eventually settle into states conforming to Schmidt-Kennicutt (S-K) relations, significant and systematic deviations of their star formation rates (SFRs) from the latter occur, especially pronounced and prolonged for ... ...This indicates potentially serious limitations of (S-K)-type relations as reliable sub-grid elements of star formation physics in simulations of structure formation in the Early Universe. We anticipate that galaxies with marked deviations from the S-K relations will be found at high redshifts as unbiased inventories of total gas mass become possible with ALMA and the EVLA.

description: We introduce and analyze a spectral vanishing viscosity approximation of periodic fractional conservation laws. The fractional part of these equations can be a fractional Laplacian or other non-local operators that are generators of pure jump Lévy processes. To accommodate for shock solutions, we first extend to the periodic setting the Kružkov-Alibaud entropy formulation and prove well-posedness. Then we introduce the numerical method, which is a non-linear Fourier Galerkin method with an additional spectral viscosity term. This type of approximation was first introduced by Tadmor for pure conservation laws. We prove that this {\em non-monotone} method converges to the entropy solution of the problem, that it retains the spectral accuracy of the Fourier method, and that it diagonalizes the fractional term reducing dramatically the computational cost induced by this term. We also derive a robust $L^1$-error estimate, and provide numerical experiments for the fractional Burgers' equation.

description: Using exact diagonalization, Monte-Carlo, and mean-field techniques, characteristic temperature scales for ferromagnetic order are discussed for the Ising and the classical anisotropic Heisenberg model on finite lattices in one and two dimensions. The interplay between nearest-neighbor exchange, anisotropy and the presence of surfaces leads, as a function of temperature, to a complex behavior of the distance-dependent spin-spin correlation function, which is very different from what is commonly expected. A finite experimental observation time is considered in addition, which is simulated within the Monte-Carlo approach by an incomplete statistical average. We find strong surface effects for small nanoparticles, which cannot be explained within a simple Landau or mean-field concept and which give rise to characteristic trends of the spin-correlation function in different temperature regimes. Unambiguous definitions of crossover temperatures for finite systems and an effective method to estimate the critical temperature of corresponding infinite systems are given.

description: In this work, we propose a new Stepped Oxide Hetero-Material Trench (SOHMT) power MOSFET with three sections in the trench gate (an N+ poly gate sandwiched between two P+ poly gates) and having different gate oxide thicknesses (increasing from source side to drain side). The different gate oxide thickness serves the purpose of simultaneously achieving (i) a good gate control on the channel charge and (ii) a lesser gate to drain capacitance. As a result, we obtain higher transconductance as well as reduced switching delays, making the proposed device suitable for both RF amplification and high speed switching applications. In addition, the sandwiched gate with different work function gate materials modifies the electric field profile in the channel resulting in an improved breakdown voltage. Using two-dimensional simulations, we have shown that the proposed device structure exhibits about 32% enhancement in breakdown voltage, 25% reduction in switching delays, 20% enhancement in peak transconductance and 10% reduction in figure of merit (product of ON-resistance and gate charge) as compared to the conventional trench gate MOSFET.

Accretion Discs with an Inner Spiral Density Wave

description: In Montgomery (2009a), we show that accretion discs in binary systems could retrogradely precess by tidal torques like the Moon and the Sun on a tilted, spinning, non-spherical Earth. In addition, we show that the state of matter and the geometrical shape of the celestial object could significantly affect the precessional value. For example, a Cataclysmic Variable (CV) Dwarf Novae (DN) non-magnetic system that shows negative superhumps in its light curve can be described by a retrogradely precessing, differentially rotating, tilted disc. Because the disc is a fluid and because the gas stream overflows the tilted disc and particles can migrate into inner disc annuli, coupled to the disc could be a retrogradely precessing inner ring that is located near the innermost annuli of the disc. However, numerical simulations by Bisikalo et al. (2003, 2004) and this work show that an inner spiral density wave can be generated instead of an inner ring. Therefore, we show that retrograde precession in non-magnetic, spinning, tilted CV DN systems can equally be described by a retrogradely precessing and differentially rotating disc with an attached retrogradely precessing inner spiral density wave so long as the wave appears at the same radius as the ring and within the plane of the tilted disc. We find that the theoretical results generated in this work agree well with the theoretical results presented in Montgomery (2009a) and thus with the numerical simulations and select CV DN systems in Montgomery (2009b) that may have a main sequence secondary. Therefore, pressure effects do need to be considered in CV DN systems that exhibit negative superhumps if the accretion discs are tilted and have an inner spiral density wave that is in the plane of the disc.

description: Ein verheerendes Erdbeben zerstörte am 26. Dezember 2003 die südiranische Stadt Bam und forderte über 36000 Menschenleben. Unter Beteiligung von dreizehn freiwilligen Helfern des Deutschen Roten Kreuzes stellte die internationale Rotkreuz- und Rothalbmondföderation die vollkommen vernichtete medizinische Infrastruktur im Erdbebengebiet für die verbliebene Bevölkerung sicher. Das System schnell einsetzbarer mobiler Gesundheitseinrichtungen (Emergency Response Units) der Rotkreuzbewegung bewährte sich auch in Bam wieder. Erstmals gelang es hierbei, auch in der Akutphase der Katastrophe ein einheitliches und für alle Organisationen verbindliches tägliches Berichtswesen durchzusetzen. Die hiermit erhobenen Fallzahlen belegen für die humanitäre Hilfe auch in einem Erdbebengebiet erneut die überragende Bedeutung der Basisgesundheitsversorgung im Sinne des Primary-Health-Care-Konzeptes gegenüber einer eher chirurgisch orientierten medizinischen Akuthilfe aus dem Ausland.
description: On December 26th, 2003, a devastating earthquake destroyed the town of Bam in southern Iran, killing at least 36000 humans. The International Federation of Red Cross and Red Crescent Societies, including thirteen volunteers of the German Red Cross, replaced the totally annihilated medical infrastructure for the remaining population in the region. As before, the system of the rapidly deployable Emergency Response Units of the Red Cross demonstrated its practical usefulness also in Bam. For the first time a compulsory standardized health reporting system on a daily base was introduced. The reported incidence data clearly indicate for an earthquake-affected region the very importance of primary health care activities in comparison with imported surgical care and facilities.

description: Первые элементы протоптеридиевой флоры на территории Горного Алтая появились в раннем эмсе. На фоне типичного нижнедевонского псилофитового комплекса в басаргинской свите содержатся остатки Protolepidodendron scharyanum (Krejči) Kr. Et W. и Gliptophyton granulare Krichtofovich, известные из живета. Элементы протоптеридиевой флоры установлены в эмских отложениях девонских прогибов Алтае-Саянской горной области. Формирование их происходило на фоне повышенной тектонической активности на вулканическом шельфе Палеоазиатского океана с регрессиями и трансгрессиями морского бассейна. Ведущая роль в их формировании принадлежала зонам разломов, поставлявшим минерализованные растворы и газы, изменявшим состав почв и приземного воздуха, что вызывало мутации растений. В качестве возможного района возникновения протоптеридиевой флоры можно рассматривать прибрежные районы Сибирского континента и в частности территорию Горного Алтая.The first elements protopteridae flora on the territory of Gorny Altai appeared in the early EMS. On the background of a typical lower Devonian psilophytales complex in Basargin Suite contains the remnants of Protolepidodendron scharyanum (Krejči) Kr. et W. and Gliptophyton granulare Krichtofovich known from Givetian. Elements protopteridae installed emski flora in the Devonian of the depressions of the Altai-Sayan mountain region. Formation occurred against the backdrop of increased tectonic activity in the volcanic shelf of the Paleoasian ocean, with regressions and transgressions of the marine basin. The leading role in its formation belonged to the fault zones, supplying saline solutions and gases modify the composition of soil and surface air, which caused mutations of plants. As a possible area of occurrence of protopteridae flora can be regarded coastal areas of the Siberian continent and in particular the territory of Gorny Altai.
