description: Interevent times in temporal contact data from humans and animals typically obey heavy-tailed distributions, and this property impacts contagion and other dynamical processes on networks. We theoretically show that distributions of interevent times heavier-tailed than exponential distributions are a consequence of the most basic metapopulation model used in epidemiology and ecology, in which individuals move from a patch to another according to the simple random walk. Our results hold true irrespectively of the network structure and also for more realistic mobility rules such as high-order random walks and the recurrent mobility patterns used for modeling human dynamics.

Characterization of water in wood below the fibre saturation point
Creators: name: Hartley, Ian Duncan
Publisher: name: University of British Columbia
Year: 2009

description: The purpose of this study was to explore the nature of water in the wood below the fibre saturation point. The approach was two-fold: (1) to experimentally determine the sorption isotherms for sapwood and heartwood of western hemlock (Tsuga heterophylla (Raf.) Sarg.) and sitka spruce (Picea sitchensis (Bong.) Carr.), and use this data to evaluate theoretical concepts; and, (2) to use pulse proton nuclear magnetic resonance (NMR) with matched specimens at moisture contents below the fibre saturation point to determine the interaction of water to the wood structure. Also, water clustering analysis of the sorption data was done using the Zimm-Lundberg water cluster theory. The inital desorption, adsorption and secondary desorption isotherms were determined and non-linear regression techniques were used to fit four sorption models to the data. The BET model did not fit very well to the data. The Dent and the H-H models were mathematically identical. Since the Le-Ly model had more parameters, it fit the data well. The equilibrium moisture contents were generally lower for the heartwood region compared to the sapwood region for the same species. The adsorption to secondary desorption ratios were found to be: hemlock sapwood: 0.830; hemlock heartwood: 0.823; spruce sapwood: 0.898; and, spruce heartwood: 0.869. Tangential and radial dimensional changes were calculated based on oven dry measurements during the sorption experiments, and it was found that they were independent of the sorption process. From the NMR experiments, moisture contents and second moments were determined from the free induction decay curve. Average relative spin densities, which were needed to calculate the moisture contents from NMR experiments, were calculated from known moisture contents and were: hemlock sapwood: 0.616; hemlock heartwood: 0.537; spruce sapwood: 0.679; and, spruce heartwood: 0.421. The second moments were higher at low moisture contents as compared to those near the fibre saturation point. The condition as to how the equilibrium moisture content was attained did not influence the second moments for hemlock; however for spruce the second moments were sorption dependent. The decay curve from the CPMG experiments was decomposed into two components for each species; a long component was determined with a T₂ > 5 ms and a short component with T₂ < 2 ms. Unfortunately, the heterogeneous and complex chemical composition of wood-water systems produced a mixture of NMR signals that were difficult to interpret relative to verifying specific concepts of cluster theory. An attempt was made to extract as much information as possible and speculate about the nature of the bound water in wood the results.

title: Synthesis, structure and function of oligo(1,8-pyrenylenes)
Creators: name: Walsh, Joshua C.
Publisher: name: Memorial University of Newfoundland
Year: 2021

description: This thesis is divided into four chapters. Chapter 1 will show progress towards a review of applications utilizing the pyrene core to show the utility of one of the most studied molecules in chemistry is far from fully realized. Chapter 2 shows a monomer‐through-pentamer series of oligo(1,8‐pyrenylene)s was synthesized using a two‐step iterative synthetic strategy. The trimer, tetramer and pentamer are mixtures of atropisomers that interconvert slowly at room temperature (VTNMR analysis). They are classified as functional molecular liquids (FMLs) well below room temperature, as indicated by POM, DSC and SWAXS analysis. The oligomers are highly fluorescent both in the liquid state and in dilute solution and an investigation of their photophysical properties demonstrated that delocalization plays a larger role in their excited states than it does in related pyrene‐based oligomers. Chapters 3 and 4 outline progress in using the oligomers as starting points for different molecular systems will also be covered, attempting to put more ‘F’ in the FMLs.

description: Properties of the distribution of single-particle levels adjacent to the Fermi surface in finite Fermi systems are studied, focusing on the case in which these levels are degenerate. The interaction of the quasiparticles occupying these levels lifts the degeneracy and affects the distance between the closest levels on opposite sides of the Fermi surface, as the number of particles in the system is varied. In addition to the familiar scenario of level crossing, a new phenomenon is uncovered, in which the merging of single-particle levels results in the disappearance of well-defined single-particle excitations. Implications of this finding are discussed for nuclear, solid-state, and atomic systems.

description: The problem of covert communication over Multiple-Input Multiple-Output (MIMO) Additive White Gaussian Noise (AWGN) channels is investigated, in which a transmitter attempts to reliably communicate with a legitimate receiver while avoiding detection by a passive adversary. The covert capacity of the MIMO AWGN is characterized under a variational distance covertness constraint when the MIMO channel matrices are static and known. The characterization of the covert capacity is also extended to a class of channels in which the legitimate channel matrix is known but the adversary's channel matrix is only known up to a rank and a spectral norm constraint.

description: We present the scalar-tensor gravitational theory with an exponential potential in which pauli metric is regarded as the physical space-time metric. We show that it is essentially equivalent to coupled quintessence(CQ) model. However for baryotropic fluid being radiation there are in fact no coupling between dilatonic scalar field and radiation. We present the critical points for baryotropic fluid and investigate the properties of critical points when the baryotropic matter is specified to ordinary matter. It is possible for all the critical points to be attractors as long as the parameters $λ$ and $β$ satisfy certain conditions. To demonstrate the attractor behaviors of these critical points, We numerically plot the phase plane for each critical point. Finally with the bound on $β$ from the observation and the fact that our universe is undergoing an accelerating expansion, we conclude that present accelerating expansion is not the eventual stage of universe. Moreover, we numerically describe the evolution of the density parameters $Ω$ and the decelerating factor $q$, and computer the present values of some cosmological parameters, which are consistent with current observational data.

Publisher: name: UPLanD - Journal of Urban Planning, Landscape & environmental Design
Year: 2019

description: In all the world, cities have facing challenges connected with extreme weather phenomena. The complexity, which characterizes urban areas, requires an integrated and interdisciplinary approach to define policies and strategies to manage this kind of problems. Urban green infrastructure, and in general, green infrastructure, may represent a concrete and sustainable approach to face problems concerning surface water management, entailing economic and environmental benefits. Sustainable urban drainage concerns techniques and technologies, considered more sustainable than conventional solutions, used to drain superficial water deriving from meteorological events. Despite the numerous advantages of sustainable urban drainage systems and urban green infrastructure, their use is still limited within urban areas and local plans pay little attention to these unconventional approaches. From this context, the study aims at analyzing the implementation of sustainable urban drainage systems and urban green infrastructure within municipal masterplans in order to understand if and to what extent these approaches are included within spatial planning at the local level. In particular, the study analyses the municipal masterplans of two Sardinian municipalities that have recently approved their plan.

Immunological suppression of central nervous system (CNS) myelin and the effect of myelin suppression on CNS repair after injury
Creators: name: Keirstead, Hans Stegmann
Publisher: name: University of British Columbia
Year: 2009

description: In higher vertebrates, axons within the differentiated central nervous system (CNS) possess a very limited capacity for repair after injury. The following experiments were designed to determine the contributions of CNS myelin to the lack of regeneration observed following transection of the late embryonic and hatchling chick spinal cord. The developmental onset of myelination in the chick begins at embryonic day (E) 13 of the 21 day developmental period. Spinal cord transections after the developmental onset of myelination result in little or no neuroanatomical repair or functional recovery. However, intraspinal injection of complement-binding galactocerebroside (GalC) antibodies or 04 antibodies (which react with sulfatide, seminolipid and an unidentified antigen on oligodendrocyte progenitors) plus complement between E9-E12 results in a delay in the onset of myelination until E17 (developmental myelin-suppression). A subsequent transection of the spinal cord as late as El 5 (i.e. during the normal restrictive period for repair) results in complete neuroanatomical regeneration and functional recovery. Spinal cord transections on El5 in a normally-myelinated embryo result in no neuroanatomical regeneration or functional recovery. These findings indicate that CNS myelin is inhibitory to the functional regeneration of transected spinal cord in embryonic chick (Keirstead et al. 1992). These studies also suggest that myelin suppression might also facilitate regeneration after adult spinal cord injury. Hatchling chickens are precocial and their brainstem and spinal cord can be considered in all respects adult-like. Administration of complement-binding GaIC antibodies or 04 antibodies plus complement to the hatchling spinal cord results in the transient removal of spinal cord myelin (immunological demyelination). The thoracic cord of posthatching day (P)2-P10 chickens were completely transected and immunological demyelination was simultaneously initiated. Fourteen to 28 days later, retrograde tract tracing, including double-labeling studies, indicated that approximately 5-15% of the brainstem-spinal projections had regenerated across the transection site to lumbar levels. Even though voluntary locomotion was not observed after recovery, focal electrical stimulation of identified brainstem locomotor regions evoked either stepping movements or ‘fictive’ stepping in paralysed animals (collaborative studies, see chapter 5). This indicates that the transient demyelination of injured hatchling (i.e. mature) chick spinal cord facilitated axonal regeneration resulting in some functional synaptogenesis with spinal neurons.

description: The Klein-Gordon and the Dirac equations with vector and scalar potentials are investigated under a more general condition, $V_{v}=V_{s} + \mathrm{const.}$ These isospectral problems are solved in a case of squared trigonometric potential functions and bound states for either particles or antiparticles are found. The eigenvalues and eigenfuntions are discussed in some detail. It is revealed that a spin-0 particle is better localized than a spin-1/2 particle when they have the same mass and are subject to the same potentials.

description: A single gene, regulating its own expression via a positive feedback loop, constitutes a common motif in gene regulatory networks and signalling cascades. Recent experiments on the development of competence in the bacterial population \emph{B. subtilis} show that the autoregulatory genetic module by itself can give rise to two types of cellular states. The states correspond to the low and high expression states of the master regulator ComK. The high expression state is attained when the ComK protein level exceeds a threshold value leading to a full activation of the autostimulatory loop. Stochasticity in gene expression drives the transitions between the two stable states. In this paper, we explain the appearance of bimodal protein distributions in \emph{B. subtilis} cell population in the framework of three possible scenarios. In two of the cases, bistability provides the basis for binary gene expression. In the third case, the system is monostable in a deterministic description and stochasticity in gene expression is solely responsible for the appearance of the two expression states.

description: The interaction between a straight vortex line in a superconducting film and a soft magnetic nanodisk in the magnetic vortex state in the presence of a magnetic field applied parallel to the film surfaces is studied theoretically. The superconductor is described by London theory and the nanodisk by the Landau-Lifshitz continuum theory of magnetism, using the approximation known as the rigid vortex model. Pinning of the vortex line by the nanodisk is found to result, predominantly, from the interaction between the vortex line and the changes in the nanodisk magnetization induced by the magnetic field of the vortex line and applied field. In the context of the rigid vortex model, these changes result from the displacement of the magnetic vortex. This displacement is calculated analytically by minimizing the energy, and the pinning potential is obtained. The applied field can tune the pinning potential by controlling the displacement of the magnetic vortex. The nanodisk magnetization curve is predicted to change in the presence of the vortex line

description: Monte Carlo simulations are one of the major tools in statistical physics, complex system science, and other fields, and an increasing number of these simulations is run on distributed systems like clusters or grids. This raises the issue of generating random numbers in a parallel, distributed environment. In this contribution we demonstrate that multiple linear recurrences in finite fields are an ideal method to produce high quality pseudorandom numbers in sequential and parallel algorithms. Their known weakness (failure of sampling points in high dimensions) can be overcome by an appropriate delinearization that preserves all desirable properties of the underlying linear sequence.

description: The Satisfiability (SAT) problem is central in computing theory for two basic reasons. First because it is the core of NP-complete problems and second because several problems of scientific and technological applications are reduced to it. Several algorithms have already being developed and they are still being developed continuously solving SAT problem. The present thesis initially presents the problem and several major subclasses the most of which are solved in polynomial time. It also refers to heuristics and metaheuristics that solve optimization problems. These heuristic and metaheuristic methods, then, are applied in the Satisfiability problem and experimental results and performance comparisons of these are given. Finally we summarize some applications of the SAT problem in several scientific areas and future research directions for the Satisfiability problem.

description: Deep learning and data-driven approaches have shown great potential in scientific domains. The promise of data-driven techniques relies on the availability of a large volume of high-quality training datasets. Due to the high cost of obtaining data through expensive physical experiments, instruments, and simulations, data augmentation techniques for scientific applications have emerged as a new direction for obtaining scientific data recently. However, existing data augmentation techniques originating from computer vision, yield physically unacceptable data samples that are not helpful for the domain problems that we are interested in. In this paper, we develop new data augmentation techniques based on convolutional neural networks. Specifically, our generative models leverage different physics knowledge (such as governing equations, observable perception, and physics phenomena) to improve the quality of the synthetic data. To validate the effectiveness of our data augmentation techniques, we apply them to solve a subsurface seismic full-waveform inversion using simulated CO$_2$ leakage data. Our interest is to invert for subsurface velocity models associated with very small CO$_2$ leakage. We validate the performance of our methods using comprehensive numerical tests. Via comparison and analysis, we show that data-driven seismic imaging can be significantly enhanced by using our data augmentation techniques. Particularly, the imaging quality has been improved by 15% in test scenarios of general-sized leakage and 17% in small-sized leakage when using an augmented training set obtained with our techniques.

description: A major difficulty in understanding the etiology and pathogenic mechanisms of rheumatoid arthritis has been the lack of a suitable animal model. Based on the MRL-lpr spontaneous arthritis model, a new murine arthritis model was developed, that is reliable and practical for therapeutic evaluations. The MRL-lpr mouse strain develops an early autoimmune disease. After the characterization of our colony, it was concluded that while the strain did not exhibit differences in the lupus-like syndromes, the spontaneous arthritis became less severe than originally described. To enhance the spontaneous arthritis of MRL-lpr mice, the effect of complete Freund’s adjuvant (CFA) was investigated. In contrast to the low percentage observed in control animals, 67-82% of mice showed clinical evidence of arthritis. Similarly, the histopathological and immunohistological analyses of the CFA injected mice indicated a significantly higher frequency of inflammation, cartilage erosion and pannus formation, with marked infiltration of activated inflammatory cells, including lymphocytes. The requirement of the lpr gene and background MRL genes was then examined. It was found that while both 7 month old MRL-+ and 3 month old MRL-lpr mice developed arthritis, B6, B6-lpr, and 3 month old MRL-+ did not display the condition after CFA-treatment. These observations suggest that while the lpr gene causes a more severe early effect, background genes other than the lpr are also involved in the disease. The effect of pregnancy, as another possible enhancing factor, was also investigated. Sixty-eight percent of female MRL-lpr mice developed a post partum exacerbation of their mild spontaneous arthritis. Post-partum or post adjuvant-injection administration of estradiol prevented the enhancement of arthritis. The effectiveness of a recently developed photodynamic therapy (PDT) was also assessed and compared with conventional experimental therapies in the treatment of adjuvant arthritis. PDT inhibited the development of adjuvant enhanced arthritis with similar effectiveness as the conventional treatments, but without their negative side effects. These results illustrate that CFA-enhancement results in a reproducible model of murine arthritis, which is useful in evaluating experimental therapeutic regimes, and demonstrating effectiveness of PDT arthritis therapy.

description: In this work, we consider a modification of the usual Branching Random Walk (BRW), where we give certain independent and identically distributed (i.i.d.) displacements to all the particles at the $n$-th generation, which may be different from the driving increment distribution. This model was first introduced by Bandyopadhyay and Ghosh (2021) and they termed it as Last Progeny Modified Branching Random Walk (LPM-BRW). Under very minimal assumptions, we derive the large deviation principle (LDP) for the right-most position of a particle in generation $n$. As a byproduct, we also complete the LDP for the classical model, which complements the earlier work by Gantert and Höfelsauer (2018).

Mean-field vs. stochastic models for transcriptional regulation
Creators: name: Blossey, R.

Year: 2008

description: We introduce a minimal model description for the dynamics of transcriptional regulatory networks. It is studied within a mean-field approximation, i.e., by deterministic ode's representing the reaction kinetics, and by stochastic simulations employing the Gillespie algorithm. We elucidate the different results both approaches can deliver, depending on the network under study, and in particular depending on the level of detail retained in the respective description. Two examples are addressed in detail: the repressilator, a transcriptional clock based on a three-gene network realized experimentally in E. coli, and a bistable two-gene circuit under external driving, a transcriptional network motif recently proposed to play a role in cellular development.

description: Η επαγγελματική και επιχειρηματική ελευθερία του εθνικού δικαίου, ως συνταγματικά προστατευόμενα ατομικά δικαιώματα αμυντικού χαρακτήρα, επιδέχονται περιορισμούς προς τον σκοπό προστασίας της δημόσιας υγείας, έναν ευαίσθητο τομέα αυξημένου ενδιαφέροντος τόσο για τις εθνικές κυβερνήσεις όσο και για την Ευρωπαϊκή Ένωση. Σε επίπεδο ενωσιακού δικαίου αντίστοιχα, οι ελευθερίες εγκατάστασης, παροχής υπηρεσιών και ανταγωνισμού δύνανται να περιορίζονται χάριν προστασίας της δημόσιας υγείας. Ο δικαστικός έλεγχος αυτών των περιορισμών, τόσο ως προς τη συνταγματικότητά τους όσο και ως προς την συμβατότητά τους, με τη χρήση της αρχής της αναλογικότητας, αφενός ποικίλλει ως προς την ένταση με την οποία ασκείται, ανάλογα με την επιβάρυνση που προκαλείται επί των παραπάνω ελευθεριών, αφετέρου -δεδομένης της διαπλοκής και της διαλεκτικής σχέσης των εθνικών και ενωσιακών κανόνων- έχει ως αποτέλεσμα την άσκηση επιρροής στις έννοιες που αφορούν στις διάφορες οικονομικές δραστηριότητες και τους φορείς αυτών, τη μεταβολή των εννοιών του εθνικού δικαίου προς την κατεύθυνση που προδιαγράφει το ενωσιακό δίκαιο, καθώς και στην ολοένα και αυξανόμενη τάση άρσης των περιορισμών προς την προώθηση του ανταγωνισμού και την φιλελευθεροποίηση της αγοράς.
description: The professional and business freedom of the national law, as constitutionally protected individual rights of defensive nature, are amenable to restrictions for the purpose of protection of public health, a sensitive area of heightened interest for both national governments and the European Union. Respectively, in terms of european law, the freedoms of establishment, to provide services and of competition may be restricted for the protection of public health. The judicial review of those limitations, with regard to both their constitutionality and their conventionality, using the principle of proportionality, on one hand varies concerning the intensity with which it is excersised, depending on the charges induced on the above freedoms, on the other part -given the interweaving and the dialectical relationship of national and european rules- results in influencing the concepts relating to various economic activities and their carriers, changing the notions of the national law towards the direction specified by the EU law, and in the ever increasing tendency to the removal of restrictions in order to promote competition and the liberalization of the market.

description: Σκοπός της διατριβής είναι η παρουσίαση ενός θεωρητικού μοντέλου για την εξεύρεση της βέλτιστης στρατηγικής μεταξύ κλειστού και ανοιχτού λογισμικού, εστιάζοντας στην ποιότητα του λογισμικού, που γίνεται αντιληπτή από τον χρήστη, σύμφωνα με την μέθοδο των δικαιωμάτων προαίρεσης. Ωστόσο, ιδιαίτερη έμφαση δίνεται στην δυνατότητα διπλής αδειοδότησης του λογισμικού. Με τη διπλή αδειοδότηση, μια εταιρεία απελευθερώνει το ίδιο προϊόν λογισμικού τόσο με την παραδοσιακή ιδιόκτητη άδεια χρήσης όσο και με μια άδεια χρήσης ανοιχτού κώδικα. Αρχικά γίνεται μια ανάλυση των κυριότερων παραδοσιακών μεθόδων αξιολόγησης των επενδύσεων, έτσι ώστε να αποτελέσει σημείο αναφοράς για τη σύγκριση των μεθόδων αυτών με τη μέθοδο των δικαιωμάτων προαίρεσης. Στη συνέχεια περιγράφεται η θεωρία των δικαιωμάτων προαίρεσης, καθώς και η μεθοδολογία και τα κύρια χαρακτηριστικά τους. Επίσης πραγματοποιείται μια διάκριση των διαφόρων κατηγοριών δικαιωμάτων προαίρεσης όπως παρουσιάζεται στην βιβλιογραφία. Επιπλέον αναλύθηκε η εφαρμογή των real options στην τεχνολογία λογισμικού, καθώς επίσης και τα μοντέλα αξιολόγησης της ποιότητας του λογισμικού. Ακόμη αναφερθήκαμε αναλυτικά στο ελεύθερο λογισμικό και στο λογισμικό ανοιχτού κώδικα. Έπειτα από την ανάλυση του θεωρητικού υπόβαθρου παρουσιάστηκε το προτεινόμενο μοντέλο.
description: The aim of the current thesis is the presentation of a theoretical model to study the optimal strategy for a firm between closed and open source software. The output of that thesis focuses on software quality perceived by the user’s view, according to the theory of Real Options Analysis. However, great emphasis is given to the term of dual licensing software. With the term dual licensing, a firm’s software product release is conducting under both a traditional proprietary and an open source license. Basically, it is analyzed the main traditional investment methods, so as to effectively compare them with the method of Real Options Analysis. In addition, the Real Options theory, its methodology and its main characteristics are merely described. A discrimination among several real options categories is presented as it has been reported in bibliography. Moreover, the Real Options enhancement in the Software Engineering domain as long as the Software Quality evaluation models, has been extensively analyzed. It is also referred in that thesis the open source term and its equivalent software. Finally, after the theoretical background the proposed model is presented.
