Full textAbstract:
A recent advancement in modeling was the development of quantum Bayesian networks (QBNs). QBNs generally differ from BNs by substituting traditional Bayes calculus in probability tables with the quantum amplification wave functions. QBNs can solve a variety of problems which are unsolvable by, or are too complex for, traditional BNs. These include problems with feedback loops and temporal expansions; problems with non-commutative dependencies in which the order of the specification of priors affects the posterior outcomes; problems with intransitive dependencies constituting the circular dominance of the outcomes; problems in which the input variables can affect each other, even if they are not causally linked (entanglement); problems in which there may be >1 dominant probability outcome dependent on small variations in inputs (superpositioning); and problems in which the outcomes are nonintuitive and defy traditional probability calculus (Parrondo’s paradox and the violation of the Sure Thing Principle). I present simple examples of these situations illustrating problems in prediction and diagnosis, and I demonstrate how BN solutions are infeasible, or at best require overly-complex latent variable structures. I then argue that many problems in ecology and evolution can be better depicted with ecological QBN (EcoQBN) modeling. The situations that fit these kinds of problems include noncommutative and intransitive ecosystems responding to suites of disturbance regimes with no specific or single climax condition, or that respond differently depending on the specific sequence of the disturbances (priors). Case examples are presented on the evaluation of habitat conditions for a bat species, representing state-transition models of a boreal forest under disturbance, and the entrainment of auditory signals among organisms. I argue that many current ecological analysis structures—such as state-and-transition models, predator–prey dynamics, the evolution of symbiotic relationships, ecological disturbance models, and much more—could greatly benefit from a QBN approach. I conclude by presenting EcoQBNs as a nascent field needing the further development of the quantum mathematical structures and, eventually, adjuncts to existing BN modeling shells or entirely new software programs to facilitate model development and application.

Full textAbstract:
As a discrete-time quantum walk model on the one-dimensional integer lattice Z , the quantum walk recently constructed by Wang and Ye [Caishi Wang and Xiaojuan Ye, Quantum walk in terms of quantum Bernoulli noises, Quantum Information Processing 15 (2016), 1897–1908] exhibits quite different features. In this paper, we extend this walk to a higher dimensional case. More precisely, for a general positive integer d ≥ 2 , by using quantum Bernoulli noises we introduce a model of discrete-time quantum walk on the d-dimensional integer lattice Z d , which we call the d-dimensional QBN walk. The d-dimensional QBN walk shares the same coin space with the quantum walk constructed by Wang and Ye, although it is a higher dimensional extension of the latter. Moreover we prove that, for a range of choices of its initial state, the d-dimensional QBN walk has a limit probability distribution of d-dimensional standard Gauss type, which is in sharp contrast with the case of the usual higher dimensional quantum walks. Some other results are also obtained.

Full textAbstract:
AbstractThe Middle Zone (MZ) of the Insch intrusion lies in a geographically intermediate position between the Lower Zone (LZ) and Upper Zone (UZ) cumulate sequences, but is more complicated than either in comprising two intricately associated, but texturally distinct, components, the MZ cumulates and the fine-grained granular gabbros (FGG). In addition, there is a minor group of porphyritic granular gabbros (PGG), containing abundant plagioclase phenocrysts. A further variety of gabbroic rock, namely quartz-biotite norite (QBN) occupies a similarly intermediate position in the Boganclogh extension of the main Insch mass. These principal components (MZ cumulates, FGG, and QBN) show considerable mineralogical overlap with each other and with the lower part of the UZ succession (UZa). Unlike the UZ rocks, they are essentially olivine-free (apart from the most basic granular gabbros) and consist mainly of plagioclase, orthopyroxene, and Ca-rich clinopyroxene, with accessory Fe-Tioxides and minor interstitial biotite and/or hornblende. Mineral compositions are in the range An70–55 (plagioclase), En71–44 (opx), and Ca46Mg42Fe12 to Ca45Mg30Fe25 (cpx), but in detail each rock group can be characterized mineralogically as well as texturally. It is concluded that the MZ cumulates and FGG (including PGG) are essentially complementary, formed in different locations, and under slightly different conditions, but in the same magma chamber. The complex relationships between them, and the apparently haphazard geographical variations in mineral compositions, may be the combined results of the magmatic events, possibly including the movement of large xenolithic fragments, and later block faulting. The substantial compositional overlap of the more evolved MZ cumulates by UZa is explained in terms of replenishment by magma of slightly more primitive (and potentially olivine-bearing) composition after the deposition of the MZ. The Boganclogh QBN is believed to represent a more hydrous fraction of the Insch MZ magma.

O progresso científico e tecnológico das nações, condição crucial para a eliminação das diferenças econômicas e sociais entre os países da comunidade internacional é, paradoxalmente, responsável pela proliferação de armas de destruição em massa, especialmente as nucleares. Esse artigo evidencia a importância dos países mais avançados nessa área de promoverem o desenvolvimento tecnológico de outros e, ao mesmo tempo, impedirem a proliferação de armas de destruição em massa. As relações de dependência tecnológica entre as potências ocidentais e os países da América Latina são utilizadas para ilustrar a necessidade de mudanças nesse sentido, pois as tecnologias químicas, biológicas, nucleares e radioativas presentes em armas QBNR, também significam remédios, fertilizantes, alimentos e tratamentos médicos. A tradição de paz da América Latina e seu desenvolvimento científico e tecnológico significam um Ocidente mais forte e mais justo.

Full textAbstract:
Prodigiosin (Pg), a secondary metabolism produced by numerous bacterial species, is known as anticancer, antibacterial, antifungal, immunosuppressant, antioxidant, antimalarial properties. Pg has been tested for antitumor activity in many different cancer cell lines but studies in LU-1, KB cell lines, and tumor-bearing mice are still limited. In this study, Serratia marcescens QBN VTCC 910026 strain (GenBank: KX674054.1) was mutated using Ethyl Methanesulfonate (EMS) to increase the production of Pg. One strain known as EMS 5 was capable of increasing prodigiosin biosynthetic yield by 52% when compared to the wild-type strain. Red bacterial pigmented colonies containing Pg were collected from solid media, lysed with acetone, purified with toluene: ethyl acetate at a ratio of 9: 1 (v/v), and then used to evaluate the potential anticancer activity. The purity of Pg was confirmed using a high-performance liquid chromatography (HPLC) method which indicated a 98% rate. Pg chemical formula which was determined using 1H-NMR and 13C-NMR spectroscopy, confirmed as prodigiosin (Pg). Human breast cancer cell lines MCF-7, oropharyngeal cancer KB, and particularly lung cancer LU-1 in vitro were used to test the anticancer activity of purified Pg compound. It showed a strong inhibitory ability in all the cancer cell lines. Furthermore, the isolated Pg had capable of inhibiting tumor growth, the tumor volume decreased by 36.82%, after 28 days. The results indicated that the bacterial prodigiosin from variants Serratia marcescens QBN VTCC 910026 strain is an encouraging fragment suitable for therapeutic applications.

Full textAbstract:
Quantum Bernoulli noises (QBN) are the family of annihilation and creation operators acting on Bernoulli functionals, which satisfy a canonical anti-commutation relation in equal-time. In this paper, we aim to investigate quantum Feller semigroups in terms of QBN. We first investigate local structure of the algebra generated by identity operator and QBN. We then use our new results obtained here to construct a class of quantum Markov semigroups from QBN which enjoy Feller property. As an application of our results, we examine a special quantum Feller semigroup associated with QBN, when it reduced to a certain Abelian subalgebra, the semigroup gives rise to the semigroup generated by Ornstein–Uhlenbeck operator. Finally, we find a sufficient condition for the existence of faithful invariant states that are diagonal for the semigroup.

Full textAbstract:
Open quantum walks (OQWs) (also known as open quantum random walks) are quantum analogs of classical Markov chains in probability theory, and have potential application in quantum information and quantum computation. Quantum Bernoulli noises (QBNs) are annihilation and creation operators acting on Bernoulli functionals, and can be used as the environment of an open quantum system. In this paper, by using QBNs as the environment, we introduce an OQW on a general higher-dimensional integer lattice. We obtain a quantum channel representation of the walk, which shows that the walk is indeed an OQW. We prove that all the states of the walk are separable provided its initial state is separable. We also prove that, for some initial states, the walk has a limit probability distribution of higher-dimensional Gauss type. Finally, we show links between the walk and a unitary quantum walk recently introduced in terms of QBNs.

Molecular Evolution is the key to explain the divergence of species and the origin of life on earth. The main task in the study of molecular evolution is the reconstruction of evolutionary trees from sequences data of the current species. This thesis introduces a novel algorithm for inferring evolutionary trees from genetic data using quartet-based approach. The new method recursively merges sub-trees based on a global statistical provided by the global quartet weight matrix. The quarte weights can be computed using several methods. Since the quartet weights computation is the most expensive procedure in this approach, the new method enables the parallel inference of large evolutionary trees. Several techniques developed to deal with quartets inaccuracies. In addition, the new method we developed is flexible in such a way that can combine morphological and molecular phylogenetic analyses to yield more accurate trees. Also, we introduce the concept of critical point where more than one possible merges are possible for the same sub-tree. The critical point concept can provide information about the relationships between species in more details and show how close they are. This enables us to detect other reasonable trees. We evaluated the algorithm on both synthetic and real data sets. Experimental results showed that the new method achieved significantly better accuracy in comparison with existing methods.

Yee, Ethan Leong. "The Burden of Forgiveness: Franciscans’ Impact on Penitential Practices in the Thirteenth Century." Thesis, 2019. https://doi.org/10.7916/d8-qbmj-zr04.
Full textAbstract:
This dissertation explores the activities of the Friars Minor relating to penance, seeking to identify the distinctive characteristics of their penitential ideals and practices and understand how they affected the penitential lives of those around them. The first three chapters draw from sources dating to the thirteenth and occasionally early fourteenth centuries from all over Western Christendom, while the last two chapters use sources mainly from thirteenth-century Northern Italy. In the Franciscan Summae confessorum, handbooks for confessors, three distinctive Franciscan penitential ideals emerge: a willingness to undermine the established order of the Church in order to gain more influence in the penitential forum; a desire for more lenient interrogation methods and imposition of penances; and a conception of indulgences as a normal part of the penitential process rather than as extraordinary privileges. These ideals influenced the way Franciscans directed penitential policy when they became prominent under the Franciscan pope Nicholas IV. Absolution and dispensation were made more available through delegation, bishops were left out of the process, and indulgences were granted in larger numbers. Franciscan penitential ideals also spread to the laity through preaching. Franciscans’ emphasis on lenient penances was paired with sermons that urged the laity to do lifelong penance and exalted their spiritual status. Franciscan spiritual advice also moved holy women such as Angela of Foligno and Margaret of Cortona to moderate their excessive penitential practices, seek out indulgences, and criticize prelates. But many lay people resisted Franciscan influence, such as the confraternities of Florence who rejected Franciscan guidance. In general, there was a relationship of mutual influence between the friars and laity in which the friars aimed to control penitential practice to some extent, but also left room for and encouraged lay autonomy, which can be seen in testaments from Bologna.

Full textAbstract:
The chapter describes a multilayer quantum backpropagation neural network (QBPNN) architecture to predict the removal of phenol from aqueous solution by orange peel ash, guided by the application of three types of activation functions and characterized by backpropagation of errors. These activation functions are Sigmoid function, tanh function and tan1.5h function. First by a classical multilayer neural network architecture with three types of activation functions is discussed in this chapter. It takes 6000000 iterations to train the network with a learning rate of 0.01. Among these three types of activation functions tan1.5 function shows the best prediction result. Next, QBPNN is discussed in this chapter. It takes 22000 iterations to train the network with the same learning rate. Here also tan1.5h function shows the best result in prediction of removal of phenol. Thus QBPNN is much faster than the classical multilayer neural network architecture. Different graphs are also given for comparison between the experimental output and network output using different activation functions. This particular chapter basically deals with a model application by which experimental results can be comparing with the model output. Because of their reliable, robust, and salient characteristics in capturing the non-linear relationships existing between variables (multi-input/output) in complex systems, it has become apparent that numerous applications of ANNs/QBNN have been successfully conducted in various parts of environmental engineering. Fuzzy Logic is also used as alternate method to predict the removal of phenol from aqueous solution by orange peel ash, but QBPNN shows the best result.
