description: This volume contains the proceedings of MARS 2015, the first workshop on Models for Formal Analysis of Real Systems, held on November 23, 2015 in Suva, Fiji, as an affiliated workshop of LPAR 2015, the 20th International Conference on Logic for Programming, Artificial Intelligence and Reasoning. The workshop emphasises modelling over verification. It aims at discussing the lessons learned from making formal methods for the verification and analysis of realistic systems. Examples are: (1) Which formalism is chosen, and why? (2) Which abstractions have to be made and why? (3) How are important characteristics of the system modelled? (4) Were there any complications while modelling the system? (5) Which measures were taken to guarantee the accuracy of the model? We invited papers that present full models of real systems, which may lay the basis for future comparison and analysis. An aim of the workshop is to present different modelling approaches and discuss pros and cons for each of them. Alternative formal descriptions of the systems presented at this workshop are encouraged, which should foster the development of improved specification formalisms.

description: Mutation is one of the most important stages of the genetic algorithm because of its impact on the exploration of global optima, and to overcome premature convergence. There are many types of mutation, and the problem lies in selection of the appropriate type, where the decision becomes more difficult and needs more trial and error. This paper investigates the use of more than one mutation operator to enhance the performance of genetic algorithms. Novel mutation operators are proposed, in addition to two selection strategies for the mutation operators, one of which is based on selecting the best mutation operator and the other randomly selects any operator. Several experiments on some Travelling Salesman Problems (TSP) were conducted to evaluate the proposed methods, and these were compared to the well-known exchange mutation and rearrangement mutation. The results show the importance of some of the proposed methods, in addition to the significant enhancement of the genetic algorithm's performance, particularly when using more than one mutation operator.

description: The assistance of thin film deposition with low-energy ion bombardment influences their final properties significantly. Especially, the application of so-called hyperthermal ions (energy <100 eV) is capable to modify the characteristics of the growing film without generating a large number of irradiation induced defects. The nitrogen ion beam assisted molecular beam epitaxy (ion energy <25 eV) is used to deposit GaN thin films on (0001)-oriented 6H-SiC substrates at 700 °C. The films are studied in situ by reflection high energy electron diffraction, ex situ by X-ray diffraction, scanning tunnelling microscopy, and high-resolution transmission electron microscopy. It is demonstrated that the film growth mode can be controlled by varying the ion to atom ratio, where 2D films are characterized by a smooth topography, a high crystalline quality, low biaxial stress, and low defect density. Typical structural defects in the GaN thin films were identified as basal plane stacking faults, low-angle grain boundaries forming between w-GaN and z-GaN and twin boundaries. The misfit strain between the GaN thin films and substrates is relieved by the generation of edge dislocations in the first and second monolayers of GaN thin films and of misfit interfacial dislocations. It can be demonstrated that the low-energy nitrogen ion assisted molecular beam epitaxy is a technique to produce thin GaN films of high crystalline quality.
Higgs pair signal enhanced in the 2HDM with two degenerate 125 GeV Higgs bosons

description: We discuss a scenario of the type-II 2HDM in which the $b\bar{b}γγ$ rate of the Higgs pair production is enhanced due to the two nearly degenerate 125 GeV Higgs bosons ($h$, $H$). Considering various theoretical and experimental constraints, we figure out the allowed ranges of the trilinear couplings of these two Higgs bosons and calculate the signal rate of $b\bar{b}γγ$ from the productions of Higgs pairs ($hh$, $hH$, $HH$) at the LHC. We find that in the allowed parameter space some trilinear Higgs couplings can be larger than the SM value by an order and the production rate of $b\bar{b}γγ$ can be greatly enhanced. We also consider a "decoupling" benchmark point where the light CP-even Higgs has a SM-like cubic self-coupling while other trilinear couplings are very small. With a detailed simulation on the $b\bar{b}γγ$ signal and backgrounds, we find that in such a "decoupling" scenario the $hh$ and $hH$ channels can jointly enhance the statistical significance to 5$σ$ at 14 TeV LHC with an integrated luminosity of 3000 fb$^{-1}$.

description: Realization and design of topological insulators emerging from electron correlations, called topological Mott insulators (TMIs), is pursued by using mean-field approximations as well as multi-variable variational Monte Carlo (MVMC) methods for Dirac electrons on honeycomb lattices. The topological insulator phases predicted in the previous studies by the mean-field approximation for an extended Hubbard model on the honeycomb lattice turn out to disappear, when we consider the possibility of a long-period charge-density-wave (CDW) order taking over the TMI phase. Nevertheless, we further show that the TMI phase is still stabilized when we are able to tune the Fermi velocity of the Dirac point of the electron band. Beyond the limitation of the mean-field calculation, we apply the newly developed MVMC to make accurate predictions after including the many-body and quantum fluctuations. By taking the extrapolation to the thermodynamic and weak external field limit, we present realistic criteria for the emergence of the topological insulator caused by the electron correlations. By suppressing the Fermi velocity to a tenth of that of the original honeycomb lattice, the topological insulator emerges in an extended region as a spontaneous symmetry breaking surviving competitions with other orders. We discuss experimental ways to realize it in a bilayer graphenesystem.

description: The field of Multi-Agent System (MAS) is an active area of research within Artificial Intelligence, with an increasingly important impact in industrial and other real-world applications. Within a MAS, autonomous agents interact to pursue personal interests and/or to achieve common objectives. Distributed Constraint Optimization Problems (DCOPs) have emerged as one of the prominent agent architectures to govern the agents' autonomous behavior, where both algorithms and communication models are driven by the structure of the specific problem. During the last decade, several extensions to the DCOP model have enabled them to support MAS in complex, real-time, and uncertain environments. This survey aims at providing an overview of the DCOP model, giving a classification of its multiple extensions and addressing both resolution methods and applications that find a natural mapping within each class of DCOPs. The proposed classification suggests several future perspectives for DCOP extensions, and identifies challenges in the design of efficient resolution algorithms, possibly through the adaptation of strategies from different areas.

description: An approach for game bot detection in MMORPGs is proposed based on the analysis of game playing behavior. Since MMORPGs are large scale games, users can play in various ways. This variety in playing behavior makes it hard to detect game bots based on play behaviors. In order to cope with this problem, the proposed approach observes game playing behaviors of users and groups them by their behavioral similarities. Then, it develops a local bot detection model for each player group. Since the locally optimized models can more accurately detect game bots within each player group, the combination of those models brings about overall improvement. For a practical purpose of reducing the workloads of the game servers in service, the game data is collected at a low resolution in time. Behavioral features are selected and developed to accurately detect game bots with the low resolution data, considering common aspects of MMORPG playing. Through the experiment with the real data from a game currently in service, it is shown that the proposed local model approach yields more accurate results.

description: We construct a new class of vacuum black hole solutions whose geometry is deformed and twisted by the presence of NUT charges. The solutions are obtained by `unspinning' the general Kerr-NUT-(A)dS spacetimes, effectively switching off some of their rotation parameters. The resulting geometry has a structure of warped space with the Kerr-like Lorentzian part warped to a Euclidean metric of deformed and/or twisted sphere, with the deformation and twist characterized by the `Euclidean NUT' parameters. In the absence of NUTs, the solution reduces to a well known Kerr-(A)dS black hole with several rotations switched off. New geometries inherit the original symmetry of the Kerr-NUT-(A)dS family, namely, they possess the full Killing tower of hidden and explicit symmetries. As expected, for vanishing NUT, twist, and deformation parameters, the symmetry is further enlarged.

Evolution of the East Antarctic ice sheet: a record from the seismic stratigraphy of the C-19 site, Ross Sea, Antarctica
Creators: name: Viator, Howard Preston
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2009

description: Nearly 1000 km of high-resolution single-channel seismic (SCS) reflection data and 1000 km of multi-channel seismic (MCS) data were acquired in the Ross Sea, Antarctica where a large iceberg, C-19, calved from the Ross Ice Shelf in May of 2002. This data set offers a unique opportunity to use a closely spaced grid of high-resolution seismic profiles to examine the glacial history of the continental shelf in an up-dip location, where older strata are closer to the surface. Two major grounding events are evident in the stratigraphic record; the first one representing the initial advance of ice onto the continental shelf during the early Miocene. During the Oligocene, prior to the onset of widespread glaciation from the East Antarctic Ice Shelf on the continental shelf, this area experienced multiple cycles (at least 10) of ice sheet advance/retreat representing an ice sheet that is approaching but not reaching the C-19 site.

description: In dieser Arbeit wird 4-4'-bis-(carbazol-9-yl)-biphenyl, CBP, mit akkuraten und effizienten quantenchemischen Methoden untersucht, um Schlüsselfaktoren für die korrekte Beschreibung angeregter Zustände zu identifizieren. Die Untersuchung der Geometrien lokaler Minima zeigt, dass die $\textit{Charge-Transfer}$-Zustände von CBP durch den $GW\!$-BSE-Ansatz mit hoher Genauigkeit beschrieben werden, während die zeitabhängige Dichtefunktionaltheorie eine falsche Reihenfolge der angeregten Zustände liefert. Es wird auch gezeigt, dass die relative Orientierung der Carbazol- und Phenylgruppen kleinere Verschiebungen der Anregungsenergie verursacht, während der Bindungsabstand der Biphenyleinheit einen stärkeren Effekt hat. Diese Beobachtungen werden durch einen Ensemble-Ansatz unterstützt, der zur Simulation der Temperaturabhängigkeit von Absorptions- und Emissionsspektren verwendet wird. Die statistische Analyse zeigt, dass die Verringerung der \textit{Charge-Transfer}-Absorptionsbanden mit einer großen Streuung in der Verteilung der Oszillatorstärken zusammenhängt, die erhebliche Veränderungen in den Übergangsmomenten widerspiegelt. Die Eigenschaften von CBP-Dimeren im angeregten Zustand werden ebenfalls untersucht. Anhand von PNO-ADC(2)-Referenzrechnungen wird gezeigt, dass TD-LC-DFTB eine gute Alternative zur Berechnung der exzitonischen Kopplungen unter Verwendung einer Zweizustandsnäherung ist. Ein Vergleich von relaxierten und nicht relaxierten Dimergeometrien aus einer MD-ausgeglichenen CBP-Auswahl zeigt, dass eine Strukturoptimierung mit Einschränkungen die Geometrien und damit die Kopplungen erheblich verbessern kann, während die Monomeranordnungen aus der Masse erhalten bleiben. Zusätzlich wird der Einfluss der expliziten Umgebung auf die Kopplungen mit Hilfe des frozen density embedding Ansatzes an CBP-Clustern untersucht. Die Verschiebungen der exzitonischen Kopplungen aufgrund der Polarisierung durch die Umgebung unterstreichen die Wichtigkeit der Berücksichtigung einer Umgebungsstruktur.

description: The first author has recently shown that semisimple algebraic groups are classified up to motivic equivalence by the local versions of the classical Tits indexes over field extensions, known as Tits p-indexes. We provide in this article the complete description of the values of the Tits p-indexes over fields. From this exhaustive study, we also deduce criteria of motivic equivalence for semisimple groups of many types, hence giving a dictionary between classic algebraic structures, representation theory, cohomological invariants and Chow motives of the twisted flag varieties for those groups.

description: Based on Brownian Dynamics computer simulations in two dimensions we investigate aggregation scenarios of colloidal particles with directional interactions induced by multiple external fields. To this end we propose a model which allows continuous change in the particle interactions from point-dipole-like to patchy-like (with four patches). We show that, as a result of this change, the non-equilibrium aggregation occurring at low densities and temperatures transforms from conventional diffusion-limited cluster aggregation (DLCA) to slippery DLCA involving rotating bonds; this is accompanied by a pronounced change of the underlying lattice structure of the aggregates from square-like to hexagonal ordering. Increasing the temperature we find a transformation to a fluid phase, consistent with results of a simple mean-field density functional theory.

description: Background: As more early career scientists enter into diverse career pathways, visiting local companies or organizations can support their exploration of these paths. As an efficient way to facilitate this, we developed a collaborative regional site visit program: the Enhancing Local Industry Transitions through Exploration (ELITE) Consortium. Consortium members arrange half-day visits to local industry sites, thus providing companies and trainees the opportunity to meet and identify potential professional and career opportunities. Three different training institutions worked cooperatively in the development and maintenance of the program. The ELITE Consortium was developed with eight phased steps; guidelines and operating procedures were created for each of these steps and are provided along with sample materials for institutions interested in building similar programs. Methods: Prior to fully developing the program, trainee interests were evaluated via questionnaire. During program implementation and thereafter, program directors tracked attendance and collected career outcome data from publicly available sources to identify first job positions after training. Regression analyses and chi-squared analyses were used to examine site visit matches and career outcome data. Results: Analyses suggest a positive impact of site visits on postdoctoral and graduate trainees’ career outcomes at companies or institutions that match a similar sector (e.g., for-profit) and type (e.g., biotech, pharmaceutical, contract research organization). Despite a small sample size, evidence suggests an especially positive impact on trainees who organize site visits to companies compared with those who simply participate. Conclusions: The ELITE Consortium was successful in helping trainees explore and identify a multitude of career paths. Trainees attained employment either directly or in related companies and institutions visited by ELITE participants. The joint, three-institution, flexible nature of the ELITE Consortium positively impacts the program’s sustainability and reach. The toolkit provided here will help other institutions to replicate and adapt the program with minimal effort.
The Relationship Between Place and Youth Volunteerism: Building Bonds and Breaking Barriers

description: Volunteerism is a popular form of community engagement among youth and can involve helping organizations, such as nonprofits, as well as directly assisting neighbours or friends through informal types of helping. A large body of research has examined the different ways in which economic, social, and cultural resources impact on volunteerism. Fewer studies have considered the influence of place characteristics. This dissertation comprises three studies. The first study used secondary data to explore the moderating effects of urban/rural place of residence and certain resources (e.g., religiosity, work status) on youths’ volunteer propensity and intensity. Results revealed significant urban/rural interactions. For example, belonging to youth groups (versus not) was particularly a strong lever for rural youth volunteerism, while higher religious attendance frequency was associated with greater volunteer intensities for urban youth. The second study used a mixed methods approach to investigate urban/rural differences in motivations for and barriers to volunteering, and skills acquired. Financial costs were associated with nonvolunteer status for rural youth, while urban nonvolunteers reported lacking interest. During the interviews, youth described reasons for volunteering, challenges to volunteering, and strategies to improve volunteerism. These discussions differed by urban/rural residence. Rural youth reported more contextual barriers, whereas urban youth questioned the significance of their impact. Rural youth discussed volunteering more as a general learning experience, whereas urban youth tended to mention specific skills they acquired (e.g., technical, interpersonal). In the third study, the relationships between perceptions of the neighbourhood environment (e.g., cohesion, amenities) and volunteer outcomes were explored. Results revealed that neighbourhood cohesion was particularly important to informal volunteering. Further, different clusters emerged based on volunteer type (informal/formal) and level of intensity. The findings from this dissertation suggest that understanding youth volunteerism within a socio-ecological perspective can widen our understanding of the volunteer process, including antecedents, challenges, experiences, and outcomes. This research may have practical implications for nonprofit organizations. For example, methods of outreach should consider how the environment impacts on volunteerism when trying to recruit young volunteers. Finally, the literature on youth volunteerism may benefit by adopting a holistic approach to volunteerism that considers the different ways in which place characteristics, rather than only individual-level factors, influence youth community engagement.

We demonstrate that an incoherent ring-shaped optical pump creating the exciton-polariton confinement supports the existence of stationary and rotating azimuthon steady states with azimuthally modulated density. Such states can be imprinted by coherent light pulses with a defined orbital angular momentum, as well as generated spontaneously in the presence of thermal noise.

description: This study will examine relationship between Army Public Affairs Officers and the dominant coalitions within Army organizations. The relationship between the two can directly affect the ability of the organization to communicate. Using components of Dominant Coalition Theory and incorporating areas from previous research, five areas that identify the level of participation in dominant coalitions by public relations personnel, training, integration and expertise, information, effectiveness of communications programs and interaction with other coalitions within the organization will be measured. Researching these areas may highlight the need for certain changes to Army training and resources for Public Affairs personnel and units.

description: We study the problem of reconstructing a signal from its projection on a subspace. The proposed signal reconstruction algorithms utilize a guiding subspace that represents desired properties of reconstructed signals. We show that optimal reconstructed signals belong to a convex bounded set, called the "reconstruction" set. We also develop iterative algorithms, based on conjugate gradient methods, to approximate optimal reconstructions with low memory and computational costs. The effectiveness of the proposed approach is demonstrated for image magnification, where the reconstructed image quality is shown to exceed that of consistent and generalized reconstruction schemes.

description: Dexterous manipulation operations using robotic or prosthetic fingers is seemingly facilitated with enhanced tactile feedback. Using a combination of artificial sensors and actuators, a tactile feedback system that conveys tactual information (force, pressure, & temperature) from an artificial fingertip to the user’s hand is developed and tested with subjects. Results reveal that subjects are capable of distinguishing specific actuators with a high degree of accuracy. The sensor density and actuator fidelity of the feedback system is insufficient to yield performance equal to that of a human’s natural tactile senses. Future studies are recommended to identify optimal tactile feedback sites as well as to discover a more robust system to be used in robotic and immersive virtual reality contexts.
Religious Transgression and Monarchy in Herodotus’ Histories
Creators: name: McCoy, Lindsey
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2017

description: This thesis investigates the role of transgressions of a religious nature in Herodotus’ Histories, beginning with a consideration of modern and ancient terminology, Herodotus’ cultural relativism, and the complicated interplay of fate and the gods within human affairs. The examination of episodes involving such transgressions reveals that these acts are particularly associated with individuals wielding power and authority, and that a transgressive relationship with religion is a symptom of monarchy, rather than of ethnicity or culture. I analyze Herodotus’ depiction of several monarchs who commit, or avoid committing, religious transgressions. These figures provide several interpretative options for readers regarding the singular character of Xerxes, and thus contribute to Herodotus’ nuanced presentation of this last Persian king, and his motives for engagement against the Greeks.
Causality - Complexity - Consistency: Can Space-Time Be Based on Logic and Computation?

description: The difficulty of explaining non-local correlations in a fixed causal structure sheds new light on the old debate on whether space and time are to be seen as fundamental. Refraining from assuming space-time as given a priori has a number of consequences. First, the usual definitions of randomness depend on a causal structure and turn meaningless. So motivated, we propose an intrinsic, physically motivated measure for the randomness of a string of bits: its length minus its normalized work value, a quantity we closely relate to its Kolmogorov complexity (the length of the shortest program making a universal Turing machine output this string). We test this alternative concept of randomness for the example of non-local correlations, and we end up with a reasoning that leads to similar conclusions as in, but is conceptually more direct than, the probabilistic view since only the outcomes of measurements that can actually all be carried out together are put into relation to each other. In the same context-free spirit, we connect the logical reversibility of an evolution to the second law of thermodynamics and the arrow of time. Refining this, we end up with a speculation on the emergence of a space-time structure on bit strings in terms of data-compressibility relations. Finally, we show that logical consistency, by which we replace the abandoned causality, it strictly weaker a constraint than the latter in the multi-party case.

description: Graph-based spectral denoising is a low-pass filtering using the eigendecomposition of the graph Laplacian matrix of a noisy signal. Polynomial filtering avoids costly computation of the eigendecomposition by projections onto suitable Krylov subspaces. Polynomial filters can be based, e.g., on the bilateral and guided filters. We propose constructing accelerated polynomial filters by running flexible Krylov subspace based linear and eigenvalue solvers such as the Block Locally Optimal Preconditioned Conjugate Gradient (LOBPCG) method.

description: We present an interpretation of the phase diagram for a binary alloy from the point of view of reaction dynamics. We consider a model system in which the two-component liquid phase is an ideal solution, but the solid phase can be non-ideal, with its non-ideality increasing with reducing temperature. We show how a ‘batch’ model for the evolution of the two-component solid–liquid system, in which the interfacial growth rates are proportional to free energy differences, leads to a set of four differential equations, whose equilibria correspond to the familiar solidus and liquidus curves. In addition, we explain how the transitions between them depend on the bifurcation structure of the solutions. We show that locally stable mixed-phase solutions can exist below the eutectic temperature, thus providing an alternative explanation for the observation of super-cooled liquids, and we also explain why complete solidification ‘normally’ occurs below the eutectic temperature, despite the fact that this temperature has no intrinsic dynamic significance, being simply a value at which two completely different equilibrium states happen to share a common liquid concentration

subject: Prevalence and mortality of IAH

description: Background: Intra-abdominal hypertension (IAH) is sustained increase in intra-abdominal pressure (IAP) ≥12 mm Hg in adults and ≥ 10 mmHg in children. [1] . IAH has been noted to be associated with increased morbidity and mortality among critically ill patients. Measurement of IAP is common among at risk patients in the developed world. However, it has not received due attention in the majority of intensive care units (ICUs) in low-income countries, Uganda being one of these. This is evidenced by paucity of data and lack of protocols from the Ugandan Ministry of Health. This multi-center study was thus conducted to assess the prevalence, incidence and associated factors of IAH among critically ill patients admitted to Ugandan ICUs. Methods: A multi-center prospective cohort study was conducted from September 2017 to February 2018 at three ICUs in Uganda. We consecutively enrolled 126 patients into the study. IAP was measured using the Harrahil manometer technique. Categorical variables were analyzed using the Chi square test and continuous variables analyzed using the t-test and Man Whitney test. The prevalence and incidence were determined using proportions and mortality was determined using survival analysis. Results: The median age was 33 years (26-48.5) for the patients without IAH and 42 years (29-55) for those with IAH. The majority of the patients were male and 9.6% of the patients were below 18 years. The prevalence of IAH was 62.7 (CI 54.1-71.3), whereas the 24 hour and 72 -hour incidence of IAH was 9.3% (CI 1.3-17.2) and 14.3 % ( CI 4.1-24.4), respectively. Mortality was higher in patients with IAH compared to those without (p-value 0.003 and 0.028, mean and maximum IAP, respectively). Conclusion: We found a high prevalence and incidence of IAH among critically ill patients, associated with a high mortality. Routine screening for IAH can preempt management strategies to mitigate this.

description: We study dynamical structure of Pure Lovelock gravity in spacetime dimensions higher than four using the Hamiltonian formalism. The action consists of cosmological constant and a single higher-order polynomial in the Riemann tensor. Similarly to Einstein-Hilbert action, it possesses a unique constant curvature vacuum and charged black hole solutions. We analyze physical degrees of freedom and local symmetries in this theory. In contrast to the Einstein-Hilbert case, a number of degrees of freedom depends on the background and can vary from zero to the maximal value carried by the Lovelock theory.

Year: 2008

description: The interaction among prescription drugs, medicine and the law is an intricate one, involving patients, doctors, government officials and drug representatives with ties to advocacy and professional organizations, and regulatory. Recent events, such as increasing rates of prescription drug abuse and overdose deaths and physician prosecutions, have intensified the conflict. This project, a series of news articles, examines the relationship between policy, pain and prescription drugs with perspectives from the fields of law enforcement, public health and medicine. It serves as a remedy to medical journalism that has largely been unwilling or unable to tease out the nuances of this complex relationship The project considers the ways that health and law enforcement institutions reconcile drugs that are critical in the treatment of pain, but also subject to widespread abuse. It seeks to answer the question: How does the complex relationship among prescription drugs, law enforcement and medicine affect the practice of pain and addiction medicine and the regulation of opioid drugs?

description: Freezing of gait (FOG) is one of the most debilitating features of Parkinson’s disease (PD). FOG may be due to a lack of central inhibition, as people with PD and FOG (PD+FOG) have difficulty inhibiting postural preparation prior to initiating stepping. We recently demonstrated that presynaptic inhibition (PSI) in the spinal cord, is crucial for coordinating postural preparation with step initiation. To investigate the feasibility of vibrotactile feedback in restoring PSI and overcome step initiation failure in PD+FOG.
