description: Tidal disruption events (TDEs) occur when a star passes close enough to a galaxy's supermassive black hole to be disrupted by tidal forces. We discuss new observations of IGRJ12580+0134, a TDE observed in NGC 4845 (d=17 Mpc) in November 2010, with the Karl G. Jansky Very Large Array (JVLA). We also discuss a reanalysis of 2010-2011 Swift and XMM-Newton observations, as well as new, late-time Swift observations. Our JVLA observations show a decay of the nuclear radio flux until 2015, when a plateau was seen, and then a significant (~factor 3) radio flare during 2016. The 2016 radio flare was also accompanied by radio spectral changes, but was not seen in the X-rays. We model the flare as resulting from the interaction of the nuclear jet with a cloud in the interstellar medium. This is distinct from late-time X-ray flares in a few other TDEs where changes in the accretion state and/or a fallback event were suggested, neither of which appears possible in this case. Our reanalysis of the Swift and XMM-Newton data from 2011 shows significant evidence for thermal emission from a disk, as well as a very soft power-law. This, in addition to the extreme X-ray flux increase seen in 2010 (a factor of >$100) bolsters the identification of IGRJ12580+0134 as a TDE, not an unusual AGN variability event.

description: As a generalization of the Log Uniform distribution, Transmuted Log Uniform distribution is introduced and its properties are studied.We obtained graphical representations of its pdf, cdf, hazard rate function and survival function. We have derived statistical properties such as moments, mean deviations, and the quantile function for the Transmuted Log-Uniform distribution. We also obtained the order statistics of the new distribution. Method of maximum likelihood is used for estimating the parameters. Estimation of stress strength parameters is also done. We applied the Transmuted Log-Uniform distribution to a real data set and compared it with Transmuted Weibull distribution and Transmuted Quasi-Akash distribution. It was found that the Transmuted Log-Uniform distribution was a better fit than the Transmuted Weibull distribution and Transmuted Quasi-Akash distribution distributions based on the values of the AIC, CAIC, BIC, HQIC, the Kolmogorov-Smirnov (K-S) goodnessoffit statistic and the p-values.

description: Context: Pluto possesses a thin atmosphere, primarily composed of nitrogen, in which the detection of methane has been reported. Aims: The goal is to constrain essential but so far unknown parameters of Pluto's atmosphere such as the surface pressure, lower atmosphere thermal stucture, and methane mixing ratio. Methods: We use high-resolution spectroscopic observations of gaseous methane, and a novel analysis of occultation light-curves. Results: We show that (i) Pluto's surface pressure is currently in the 6.5-24 microbar range (ii) the methane mixing ratio is 0.5+/-0.1 %, adequate to explain Pluto's inverted thermal structure and ~100 K upper atmosphere temperature (iii) a troposphere is not required by our data, but if present, it has a depth of at most 17 km, i.e. less than one pressure scale height; in this case methane is supersaturated in most of it. The atmospheric and bulk surface abundance of methane are strikingly similar, a possible consequence of the presence of a CH4-rich top surface layer.

Bargaining solutions to the problem of exchange of uncertain ventures
Creators: name: Weerahandi, Samaradasa
Publisher: name: University of British Columbia
Year: 2010

description: Consider the betting problem where two individuals negotiate to determine the amount each will bet. It has already been established that when the two bettors both have concave utility functions, there exist mutually beneficial bets (i.e. bets giving positive utility to both players) merely if players' subjective probabilities on the betting event differ. It is shown here that this result can be generalized to the case of more general utility functions. The results are extended to a more general situation, that of a stochastic exchange. It is shown that the set of all feasible solutions available for exchange for two risk averters is a convex set with a known boundary. After defining a solution for the members of a class of exchange models it is shown in the third chapter that the 'size' of the exchange prescribed by the solution tends to increase with the participants' initial wealth and with multiplicative shifts of the random variable characterizing the exchange. Furthermore the size of the exchange may increase or decrease due to an additive shift of this random variable. In Chapter 4 it is shown by an axiomatic method that an individual engaged in bargaining with incomplete information finds his 'fair' demand (offer) by maximizing a generalized Nash function, GNF; this GNF is found to be the product of his utility and a general mean of his opponent's uncertain utility (from first individual's point of view). This general mean is characterized by a parameter whose value may vary from person to person. Continuing the study on bargaining under incomplete information, a best bargaining strategy is developed in the last chapter using the technique of 'Backward Induction'. A criterion for comparing available bargaining strategies is also established.

description: Software Quality Analysis refers to the process of evaluating and assessing the quality of software products or applications. It involves analyzing various aspects of the software to determine its level of quality, identify potential issues or defects, and make informed decisions to expand the software's overall quality. There are investigated different software quality models based on machine learning algorithms. Nevertheless, the explored approaches have an inconsistent understanding of the software product quality and high complexity. This research presents an enhanced ensemble model (EEM) that involves Support Vector Machine (SVM), K-Nearest Neighbor (KNN), and Extreme Learning Machine (ELM) to assess the optimal outcomes. This model performance is computed based on multiple selective parameters namely functional suitability and maintainability of the software and compared along with several algorithms namely Decision Tree, Random Forest, AdaBoost, and Naive Bayes. The outcome of this ensemble model demonstrates that it offers highly accurate results for software validation, verification, and overall product development process to analyze the functional suitability as well as software maintainability. The measured accuracy on Decision Tree, Random Forest, Naive Bayes, AdaBoost, and EEM is found 92.08%, 93.35%, 94.50%, 95.60%, and 99.14%, respectively.

description: It is known that in synchronous machines with massive rotors, it is required to take into account the change in the equivalent rotor of active resistance depending on the frequency of the current in the rotor at starting of these machines. A three-phase mathematical model of these machines has been compiled, the equations of which are written in axes rotating at the speed of the machine rotor. Study of the start-up modes of these machines and operation in synchronous mode with a load surge (dynamic mode) has been carried out on this model. The studies have allowed for making the following conclusions. When starting synchronous machines with massive rotors, it is most preferable to take into account the change in the equivalent resistance in the form of a linear sliding function. It was found out that in the synchronous mode of operation of these machines, including in stable dynamic modes, there is no need to take into account changes in the rotor resistance-sliding, since the sliding in these modes oscillatory damps around zero, thereby not affecting changes in the value of the equivalent resistance. Therefore, in these modes it is recommended to consider the value of this resistance constant and definite at slip equal to zero.

Understanding DNA Deformability by DNA Bending Studies with the IHF/HU Family of Architectural Proteins
Creators: name: Connolly, Mitchell Jeffrey
Publisher: name: University of Illinois at Chicago
Year: 2021
Subjects: Uncategorized

description: Sequence-dependent DNA shape and deformability is critical to how proteins bind to DNA and kink, bend, or twist it to facilitate various cellular processes. However, many of the rules that govern local DNA shape/deformability remain largely untested, especially for severely deformed DNA. This thesis describes studies aimed at characterizing DNA deformability, utilizing a prokaryotic, architectural, DNA-bending protein Integration Host Factor (IHF) that binds to DNA both nonspecifically, to facilitate DNA packaging, and specifically, to form higher-order protein-DNA complexes for specialized functions. IHF has a remarkable ability to bend specific target sites on DNA by nearly 180 degrees over 35 base pairs, which it accomplishes by inducing two sharp kinks in the DNA. How flexible or rigid are these kinks was not known and the competition between the two binding modes was poorly characterized. Using fluorescence lifetime studies to measure Forster resonance energy transfer (FRET) efficiency between fluorescent probes attached to the ends of 35-mer DNA constructs, we showed that IHF-DNA complexes sample different conformations with varying degrees of DNA bends, indicating a highly dynamic complex. The distribution of conformations is modulated by DNA sequence variations, highlighting the finely tuned interactions between IHF and its many biological targets that keep the DNA bent (or not). Next, we used a “lattice-binding” model to simultaneously describe binding (measured by fluorescence anisotropy) and bending (measured by FRET) of IHF to specific and nonspecific DNA. These studies provided accurate measurements of the relative affinities in the two binding modes and revealed that specific and nonspecific binding likely occur simultaneously to the same DNA site at sufficiently high protein concentrations. Using laser temperature-jump spectroscopy, we established that transient Hoogsteen base pairing – a thermodynamically less favorable alternative to Watson-Crick pairing prevalent at flexible sites in duplex DNA – plays no role in facilitating DNA kinking by IHF. Finally, we performed high-throughput “SELEX” studies designed to identify highly “kinkable” DNA sequences using in vitro selection of high-affinity sequences for IHF from a pool of random DNA sequences. These SELEX studies provide a database of highly deformable sequences that can be used to improve current models of sequence-dependent DNA mechanics.

description: The performance of a juice plant is analyzed by using the base state and the regenerative point graphical technique. The juice plant under consideration consists of three distinct units. It is considered that units A and B may be in a complete failed state through partial failure mode but unit C is in only partially failed state. If one of the units A or B or C partially fails then the system works in a reduced state. When any unit is completely failed then the system is in failed state and no unit can fail further when the system is in a failed state. A technician is always available to repair the failed unit. In this paper, the failure time and repair time follow general distributions. Tables are used to describe the reliability measures such as mean time to system failure, availability and profit values of juice plant.

description: Compositionally complex materials (CCMs) present a potential paradigm shift in the design of magnetic materials. These alloys exhibit long-range structural order coupled with limited or no chemical order. As a result, extreme local environments exist with a large opposing magnetic energy term, which can manifest large changes in the magnetic behavior. In the current work, the magnetic properties of (Cr, Mn, Fe, Ni) alloys are presented. These materials were prepared by room-temperature combinatorial sputtering, resulting in a range of compositions with a single BCC structural phase and no chemical ordering. The combinatorial growth technique allows CCMs to be prepared outside of their thermodynamically stable phase, enabling the exploration of otherwise inaccessible order. The mixed ferromagnetic and antiferromagnetic interactions in these alloys causes frustrated magnetic behavior, which results in an extremely low coercivity (<1 mT), which increases rapidly at 50 K. At low temperatures, the coercivity achieves values of nearly 500 mT, which is comparable to some high-anisotropy magnetic materials. Commensurate with the divergent coercivity is an atypical drop in the temperature dependent magnetization. These effects are explained by a mixed magnetic phase model, consisting of ferro-, antiferro , and frustrated magnetic regions, and are rationalized by simulations. A machine-learning algorithm is employed to visualize the parameter space and inform the development of subsequent compositions. Annealing the samples at 600 °C orders the sample, more-than doubling the Curie temperature and increasing the saturation magnetization by as much as 5x. Simultaneously, the large coercivities are suppressed, resulting in magnetic behavior that is largely temperature independent over a range of 350 K.

description: The aim of the paper is to study effectiveness of the different treatments of early-stage breast cancer through analysis of a stochastic model. The early-stage breast cancer is a term used to describe breast cancer that is detected at an early stage of development, typically before it has spread to other parts of the body. Early detection of breast cancer is critical as it greatly increases the chances of successful treatment and saves lives. At early-stage breast cancer of the patient, two types of treatment namely, tamoxifen and tamoxifen combined with radiation therapy are commonly used. As it is essential to consider innovative and cost-effective strategies for early detection and treatment. Investigations through analysis of the stochastic model on early-stage breast cancer with these two types of treatments may help the stakeholders. Keeping this in view, in the present paper, a stochastic model is developed for the early-stage breast cancer considering two treatment types, namely tamoxifen and tamoxifen combined with radiation therapy. The model is analyzed by Markov process and regenerative point technique. Mean sojourn time refers to the average amount of time spent by a patient in a particular state before transitioning to another state and mean survival time refers to the average time a patient survives after diagnosis of breast cancer. Mean sojourn time and mean survival time have been calculated. Sensitivity analysis is a technique to understand how changes in input variables or parameters affect the output or outcome of a model and it helps assess the robustness, reliability, and stability of a model by quantifying the impact of variations in input factors. The paper also includes sensitivity and relative sensitivity analyses of the model which explore the impact of different parameters on the survivability of the patient. The MATLAB software has been used for numerical computing and plotting various graphs. The investigation through our analysis of the stochastic model shows that the mean survival time lessens with the rise in the rates of transition and mean survival time from the treatment, tamoxifen plus radiation is higher than the treatment, tamoxifen only. It is concluded that tamoxifen plus radiation is more effective and useful than only tamoxifen for treatment of early-stage breast cancer.

description: The aim of the paper is to carry out survival analysis of a novel multi-state model on infectious disease considering various levels of severity using semi-Markov processes. Various levels of severity of the disease over time and transitions between these severity levels have been considered. Transition probabilities and expected waiting times are derived. Expressions for mean survival time, expected total time in home isolation, and expected total time in hospital are obtained. The analysis of the proposed model is carried out through numerical computation and plotting several graphs. Important conclusions are drawn. The modelling framework proposed here can be used to model any infectious disease irrespective of disease states. The study will be helpful in designing effective measures to control the infectious disease and selecting the appropriate intervention policies.

Deep Learning-Aided Unimodular Quadratic Programming:Initialization and Provable Guarantees

description: In this thesis, we study an important optimization problem called “Unimodular Quadratic Program” (UQP) that has shown its presence in prominent applications such as wireless communication, active sensing, etc. UQP is an NP-hard constrained optimization problem and prior works that have proposed approximate solutions have generally suffered from the speed versus reliability trade-off. With the aim to improve the computational efficiency of existing UQP solutions and equipped with the highly scalable deep learning framework as a backbone, we propose two novel solvers for UQP. Our first solution is a black-box computational approach, which we call Deep-PMLI, where the deep learning model learns to predict a solution to a given UQP based on already seen example UQPs. Deep-PMLI is an attractive solver for applications that require low-cost solutions but do not require strong guarantees. In our second solution, Deep-INIT, we propose a novel data-driven strategy to speed-up an existing provably optimal solver for UQP. Deep-INIT, apart from achieving a significant speed-up over the underlying UQP solver, also preserves its guarantees.

description: Systems of the type linear primary or secondary amine + cyclohexane, or + polar compound (namely, linear or cyclic monoether, + 1,4-dioxane, + N,N-dialkylamide, or + ethanitrile) have been investigated using literature data, and by means of DISQUAC. Interaction parameters for the contacts amine/ether, amine/amide and amine/nitrile are provided. For a given contact, the QUAC interchange coefficients remain practically constant along each homologous series. A similar trend has been encountered in other many previous studies. DISQUAC correctly describes excess molar enthalpies, $H_{\text{m}}^{\text{E}}$, and vapour-liquid and solid-liquid equilibria of the studied mixtures and improves calculations on $H_{\text{m}}^{\text{E}}$ from the UNIFAC (Dortmund) model. The experimental data have been used to determine the enthalpy of the interactions between unlike molecules, which are stronger in systems with N,N-dialkylamides or ethanenitrile than in mixtures with ethers. On the other hand, it is shown that $H_{\text{m}}^{\text{E}}$ values of amine + C$_6$H$_{12}$ mixtures are closely related to the amine self-association, and that interactions between molecules of the polar compounds are determinant on $H_{\text{m}}^{\text{E}}$ results of the mixtures amine + fixed polar compound or of the systems fixed amine + polar compound (no linear monoether). Structural effects are relevant in the di-n-butylamine + linear ether systems. The application of the Flory model reveals that orientational effects are rather weak in the investigated solutions. This is in agreement with previous studies on this type of mixtures using the ERAS model.

description: The contemporary world is characterized by rapid and continuous transformations, which are reshaping the societies of Late Modernity, compelling them to address a multitude of uncertainties and challenges. In this context, the social being is called upon to navigate these evolving social conditions through the use of modern means. This era, marked by swift changes, faces a range of complex and difficult-to-use social issues, many of which either did not exist in traditional societies or existed on a smaller scale, lacking the degree of danger observed today. One of the most pressing social problems of the modern era is child poverty, which has become one of the central issues that social beings are called to address in contemporary society. This study aims to analyse the phenomenon of child poverty within the framework of Second Modernity, with a case study focusing on Greece during the period 2000-2020. Special emphasis will be placed on recognizing and highlighting the value of childhood through the lens of children’s right, sociology, as well as the contribution of the Church to this pressing issue.

description: Most of the urban growth is expected to happen in Low-and-Middle Income Countries (LMICs), mostly in deprived urban areas (commonly known as slums or informal settlements). Monitoring the growth, persistence, and diversity amongst deprived urban areas remains one of the primary goals of the Sustainable Development Goals (SDGs). This requires spatially explicit and accurate data. However, such data are commonly not available at global and local scale. To bridge such data gaps, IDEAMAPS developed a data-driven framework to map and characterize deprived urban areas. This framework was implemented and adapted to Khartoum, Sudan to support local decision-making. IDEeAMapSudan built together with local stakeholders a data ecosystem, which is openly accessible via a Geonode. The Geonode (http://geonode.idea-maps.net) provides data on urban deprivation in support of local actions and SDG 11 monitoring.

description: Frozen transient imbibition states in arrays of straight cylindrical pores 400 nm in diameter were imaged by phase-contrast X-ray computed tomography with single-pore resolution. A semi-automatic algorithm yielding brightness profiles along all pores identified within the probed sample volume is described. Imbibition front positions are determined by descriptive statistics. A first approach involves the evaluation of frequency densities of single-pore imbibition lengths, a second one the evaluation of the statistical brightness dispersion within the probed volume as a function of the distance from the pore mouths. We plotted average imbibition front positions against systematically varied powers of the imbibition time and determined the optimal exponent of the imbibition time by considering the correlation coefficients of the corresponding linear fits. Thus, slight deviations from the proportionality of the average imbibition front position to the square root of the imbibition time predicted by the Lucas-Washburn theory were found. A meaningful preexponential factor in the power law relating imbibition front position and imbibition time may only be determined after ambiguities regarding the exponent of the imbibition time are resolved. The dispersion of peaks representing the imbibition front in frequency densities of single-pore imbibition lengths and in brightness dispersion profiles plotted against the pore depth is suggested as measure of the imbibition front width. Phase-contrast X-ray computed tomography allows the evaluation of a large number of infiltrated submicron pores taking advantage of phase-contrast imaging; artifacts related to sample damage by tomography requiring physical ablation of sample material are avoided.

description: IP traffic has increased significantly in recent years, and it is expected that this progress will continue. Recent studies report that the viewing of online video content accounts for a share of 1% of the global greenhouse gas emissions. To reduce the data traffic of video streaming, the new standard Versatile Video Coding (VVC) has been finalized in 2020. In this paper, the energy efficiency of two different VVC decoders is analyzed in detail. Furthermore, we propose a design space exploration that uses an algorithm based on a greedy strategy to derive coding tool profiles that optimize the energy demand of the decoder. We show that the algorithm derives optimal coding tool profiles for a subset of coding tools. Additionally, we propose profiles that reduce the energy demand of VVC decoders and provide energy savings of more than 50% for sequences with 4K resolution. Thereby, we will also show that the proposed profiles can have a lower decoding energy demand than comparable HEVC-encoded bit streams while also having a significantly lower bit rate.

description: This paper presents a comprehensive study of a series-parallel system comprising four interconnected subsystems: subsystem-1, subsystem-2, subsystem-3, and subsystem-4. Subsystem-1 stands as a single unit, subsystem-2 consists of three identical units in active parallel, subsystem-3 involves two identical units in series, while subsystem-4 incorporates two identical units in parallel. The system operates under good conditions, considering various failure rates and repair rates. The investigation employs Laplace transforms and Supplementary variable techniques to analyze the system's performance. Key reliability parameters, including Availability, Reliability, Mean Time to Failure (MTTF), Sensitivity, and Cost, are evaluated for specific values of failure and repair rates. The paper delves into the intricate analysis of a multi-unit series system, focusing on its reliability and performance evaluation. The study employs the Gumbel-Hougard Family Copula approach, a sophisticated and robust methodology to capture the interdependencies among system units. By utilizing this advanced technique, the paper provides a comprehensive understanding of the system's behavior under varying operating conditions. Various reliability and performance metrics, including Availability, Mean Time to Failure (MTTF), and Component Importance Measures, are thoroughly examined, offering valuable insights for optimizing the system's reliability and performance. The results are presented in a clear and visually appealing manner, utilizing tables and figures to aid in the comprehension of the findings.

description: Die vorliegende Arbeit untersucht die Geschlechterverhältnisse in der ostdeutschen Landwirtschaft im Hinblick auf den Einfluss des agrarpolitischen Rahmens aus der lebensweltlichen Perspektive von Landwirtinnen am Beispiel Brandenburgs. Sie geht dabei der Frage nach, wie Landwirtinnen Geschlechterverhältnisse und Geschlechtergerechtigkeit in ihrem agrarischen Umfeld erleben und welchen Stellenwert für sie dabei die Agrarpolitik einnimmt. Um die Forschungsfrage zu beantworten, wurde eine empirische Befragung von sieben Brandenburger Landwirtinnen in Form von leitfadengestützten Interviews vorgenommen. Die Untersuchung zeigte, dass das landwirtschaftliche und agrarpolitische Umfeld in Brandenburg als männlich dominiert erlebt wird. Die Ergebnisse verdeutlichen, dass Geschlechterrollenbilder im landwirtschaftlichen Umfeld eine bedeutende Rolle einnehmen und insbesondere in den Bereichen Arbeitsteilung, Zuständigkeit für Care-Arbeiten oder der Nutzung von Landtechnik von Bedeutung sind. Die Einschätzungen, welche vergeschlechtlichten Auswirkungen der agrarpolitische Rahmen hat, variierten in den Interviews. Mögliche vergeschlechtlichte Auswirkungen von Agrarpolitik wurden vor allem in dem Zugang zu Land und den Direktzahlungen nach Hektar gesehen.
description: This study examines gender relations in East German agriculture with regard to the influence of the agricultural policy framework from the life-world perspective of female farmers using the example of Brandenburg. The research question analyses how women farmers experience gender relations and gender equality in their agricultural environment and the significance of agricultural policy has for them in this context. In order to answer the research question, a total of seven guided interviews were conducted with seven female farmers in Brandenburg. The study showed that agriculture and it´s policy environment in Brandenburg is experienced as male-dominated. The results show that gender role models play a significant role in the agricultural environment and are especially important in the areas of labor division, responsibility for care work or the use of agricultural technology. The perception of gendered effects of agricultural policy framework has varied in the interviews. Possible gendered effects of agricultural policy were seen primarily in access to land and direct payments per hectare.

description: This study investigates the time dependent behaviour of the single server queue with differentiated working vacations. The model also takes into account the possibility of a disaster happening during busy periods and working vacations, with the repair procedure starting right away. The time-dependent probabilities of system size are described in terms of modified Bessel functions in the paper using explicit equations that were generated using generating functions. Numeric instances have been added to support the theoretical findings even more.

description: We consider the half-wave maps (HWM) equation which is a continuum limit of the classical version of the Haldane-Shastry spin chain. In particular, we explore a many-body dynamical system arising from the HWM equation under the pole ansatz. The system is shown to be completely integrable by demonstrating that it exhibits a Lax pair and relevant conservation lows. Subsequently, the analytical multisoliton solutions of the HWM equation are constructed by means of the pole expansion method. The properties of the one- and two-soliton solutions are then investigated in detail as well as their pole dynamics. Last, an asymptotic analysis of the $N$-soliton solution reveals that no phase shifts appear after the collision of solitons. This intriguing feature is worth noting since it is the first example observed in the head-on collision of rational solitons. A number of problems remain open for the HWM equation, some of which are discussed in concluding remarks.

The Philosophy of Musical Instruments

description: Simple reflection suggests that musical instruments are central to both musical practice and experiences of music. Nevertheless, there is neither a robust philosophical literature about musical instruments themselves nor much work in the philosophy of music that considers instruments when accounting for the nature of music. The overarching claim of this dissertation is that conceptual approaches to music that overlook or minimize musical instruments are thereby impoverished. This case is made in three parts. First, I argue that one source of the neglect of the contribution of instruments to music is the set of assumptions that I call, in a variation on a theme by Arthur Danto, the philosophical disenfranchisement of instruments. Several of these assumptions, which are common in both aesthetics and the philosophy of art, have their roots in Kantian aesthetics, notably anti-instrumentalism, spectator-centered aesthetics, and the genius-model of creativity. Second, I consider applications of the disenfranchisement of instruments in the philosophy of music, including widely accepted views such as the acousmatic account of musical listening and the “pure” music paradigm. I also discuss ways in which philosophical uses of musical concepts, particularly ‘timbre,’ diverge from their uses within musical practice. This reveals a second source of the neglect of musical instruments: the work-centered approach to music, which privileges the concept ‘musical work’ over other musical concepts (e.g. ‘performance,’ ‘composition,’ ‘tone’). Finally, I make a positive case for a conceptual approach to music that acknowledges the centrality of musical instruments in musical practices and experiences. This instrument-centered approach to music, as I conceive of it, is rooted in the notion of a musical culture. Instruments are both shaped by, but also shaping of, musical cultures. They thereby contribute to both experiencing and making music.
