description: We present a hierarchy of discrete systems whose first members are the lattice modified Korteweg-de Vries equation, and the lattice modified Boussinesq equation. The N-th member in the hierarchy is an N-component system defined on an elementary plaquette in the 2-dimensional lattice. The system is multidimensionally consistent and a Lagrangian which respects this feature, i.e., which has the desirable closure property, is obtained.

description: The purpose of this queer qualitative MFA thesis is to increase visibility of LGBTQ+ youth and queer representation within popular canonical materials through the creation of a devised theatre performance with undergraduate university students. Our performance, Queering the Canon, explores what happens when “the canon” is inverted to intentionally include queer people in narratives they have previously been excluded from. My case study research asks: How can a devised theatre performance for high school students use aesthetic attributes to queer the canon and make social change? To answer this question, my acting ensemble devised an original piece of theatre which we performed for colleagues and two different high school audiences. Each interactive theatre performance concluded with opportunities for the youth participants to co-construct their own ideas on “queerness” and “the canon” as a valued part of the research process. Afterwards, I coded and analyzed key project artifacts including fieldwork notes, rehearsal products, the final script, reflective products, and ensemble interviews to consider how our devised theatre performance of Queering the Canon served as a site for change. Specifically, I use the Animating Democracy/Americans for the Arts’ Aesthetic Perspectives: Attributes of Excellence in Arts for Change framework, to make sense of how a “queered” devising process can be a site of disruption, risk-taking, cultural integrity, and communal meaning, that produces feelings of commitment through an emotional experience for those who participate.

description: The stability and reactivity of Pd6-nCun (n = 0−3) clusters supported on pyridinic N-doped graphene (PNG) were investigated using the auxiliary density functional theory method. First, the stability of Pd6-nCun (n = 0−3) clusters supported on PNG was analyzed using charge transfer, interaction energy, and electron density critical point calculations. Then, the reactivity of these clusters supported on PNG was computed using frontier molecular orbitals and oxygen adsorption energies. According to the calculated interaction energy, as the Cu content increased, the interaction energy between Pd6-nCun (n = 0−3) clusters and PNG increased. The charge transfer indicated that the clusters donate charge to the PNG. Based on the energy of the frontier orbitals, the Pd5Cu cluster supported on PNG exhibits the smallest HOMO–LUMO gap inferring that this system is the most reactive, whereas the less reactive system corresponds to the Pd4Cu2 cluster supported on PNG. Finally, the oxygen adsorption energies on Pd6 (−3.86 eV) and Pd5Cu (−3.87 eV) clusters supported on PNG were similar. However, the Pd5Cu cluster has a lower Pd content than the Pd6 cluster. Therefore, this work reveals that PdCu systems supported on PNG could be cheap and efficient catalysts for the oxygen reduction reaction.

description: Western capitalist narratives often dominate the portrayal of Russia, the Soviet Union, and the former Soviet space. With respect to reform and resistance, Western narratives benefit greatly from sweeping under the rug the enormous successes in social life and policy of places like the Soviet Union. Western feminists often attribute the beginning of feminism in Russia to the fall of the Soviet Union, and focus on its growth since. Previous research presents a monolithic narrative of womanhood in Russia, portraying Russian women as passive and oppressed, as dictated by Western feminist values. In fact, starting in the early years of the Bolshevik Revolution, Russian women worked to de-gender labor and separate women from marriage, an idea unheard of in the West in the 1910s. This paper aims to explore Russian feminism free from a Western exceptionalist lens, and to use such analysis as a model for a more inclusive, international, rebooted Marxist revolution.

Patient expertise & self-management

description: Patient expertise and self-management are terms that have been co-popularized through the success of the Chronic Disease Self-Management Program and Expert Patient Program. This review looks at the intersection of literature that focuses on both patient expertise and self-management. These concepts are not well-defined and the treatment of each of these terms in the literature is diverse and occasionally contradictory, but patient expertise is generally regarded as some form of useful health knowledge and self-management can be understood as a set of behaviors including recognizing, treating, and preventing symptoms of illness. The relationship between these concepts is not established in the literature, so this review poses six potential relationship dynamics based on how they are interrelated within the literature set. Much of the research agrees that patients should be empowered, active, and informed, and these are the goals of operationalizing patient expertise and self-management. However, barriers to these goals include negative provider attitudes, extensive labor burden, and information relevance. In addition to these barriers to achieving the stated goals of this research, the corpus also exhibits significant limitations and gaps including diagnostic specificity, institutionalized verification, assumption of diagnostic onset, and disregarding disability. These limitations inhibit the utility of the research and the gaps call for further research to enhance academic understanding of this topic area.

description: Grüner Wasserstoff wird von großen Teilen der Wirtschaft und der Politik als Allheilmittel der Energiewende hochgejubelt. Besonders attraktiv ist dabei einerseits, dass Wasserstoff durch Nutzung von Sonnenenergie bereitgestellt werden kann und andererseits, dass es sich um einen speicherbaren und transportierbaren Energieträger handelt. Damit wird die Erwartung verbunden, sowohl das bisherige Konsumverhalten beibehalten zu können als auch die derzeitige Infrastruktur der Erdgasleitungen zu nutzen. Diese Erwartung ist jedoch auf Grund der geringen Effizienz der Wasserstoff-Wertschöpfungskette nicht erfüllbar. Wasserstoff wird damit in einem nachhaltigen Energie- und Ressourcensystem eine wichtige, aber untergeordnete Rolle spielen.

description: We show that the bump in the electron number density profile at the base of the hydrogen envelope in O-Ne-Mg core-collapse supernovae causes an interesting interplay between neutrino-electron and neutrino-neutrino forward scattering effects in the flavor evolution of low-energy nu_e in the neutronization burst. The bump allows a significant fraction of the low-energy nu_e to survive by rendering their flavor evolution nonadiabatic. Increasing the luminosity of the neutronization burst shifts the bump-affected nu_e to lower energy with reduced survival probability. Similarly, lowering the luminosity shifts the bump-affected neutrinos to higher energies. While these low energy neutrinos lie near the edge of detectability, the population of bump-affected neutrinos has direct influence on the spectral swap formation in the neutrino signal at higher energies.

description: Arabic grammar traditionally recognized only three parts of speech: the noun (ism), the verb (fiʿl), and the particle (ḥarf). Over the centuries, scholars propounded a battery of criteria to assign any given word to one of these three categories, but certain word classes defied easy placement within the tripartite system. Among these were exceptives and other pseudo-verbs, and temporalizers like mud and mundu, as well as prepositions (ḥurūf ǧarr), many of which were category-ambiguous between particle and noun. The category of ka- (or kāf), “like, as,” featured prominently in this debate, with advocates of its nounhood often adducing verses of poetry in which kāf behaved as a noun. Meanwhile, opponents supplied restorations (taqādīr, sg. taqdīr) to account for aberrant usage at the surface by conventional means. Of the Andalusian grammarians, who were especially engrossed in this debate, Ibn Maḍāʾ contended that, owing to its synonymy with mitl—a proven noun—kāf had always to be a noun, even in prose. Though those of Ibn Maḍāʾ’s works germane to kāf are not thought to have survived, other grammarians record his view. Their own comments on kāf and related matters reference the main touchpoints in the discourse, without which any argument for or against kāf’s nounhood would be inadmissible. I conclude that Ibn Maḍāʾ’s minority opinion is the better portrayal of kāf because more reliable gauges of nounhood suggest as much, as does the evidence from etymological derivatives of kāf in prose.
Inkjet printing of transducers

Publisher: name: University of British Columbia
Year: 2010

description: In the past few years, inkjet printing has been emerging as a cost effective, environment friendly, net-shape microfabrication technique. This non-contact deposition technique facilitated the deposition of metallic and polymeric inks, biological proteins, and cells. The present work investigates the inkjet printing of microtransducers, with a focus on stress-sensing and movable microstructures. Piezoresistive and interdigitated capacitor based strain gauges were printed and tested. The inexpensive conductive polymer, poly(3,4-ethylenedioxythiophene) oxidized with poly(styrenesulfonate) (PEDOT:PSS), was used as base material. We have performed measurements on several test structures to show that PEDOT:PSS does preserve its piezoresistive properties after printing. As we were relying further on PEDOT:PSS as a base material for printed transducers, the mechanical and electrical properties of this commercially available ink were comprehensively investigated. A dedicated experimental setup, which was used for the mechanical and electrical characterization of test structures, and micro-topography measurements were combined in order to extract the parameters of the PEDOT:PSS thin film: a zero-stress electrical conductivity of G=201 S/cm and gauge factor of 3.63. The longitudinal and transversal piezoresistive coefficients were estimated to be, [formula omitted] and [formula omitted] respectively, which denote a piezoresistive material in a similar range of piezoresistivity as n-doped silicon and conventionally fabricated PEDOT:PSS. A second explored direction was using inkjet microprinting technology for the fabrication of movable microstructures. An inkjet-printed CMUT (capacitive micromachined ultrasound transducer) was the target device, using ZnO as sacrificial layer and PEDOT:PSS as structural layer. The printed ZnO sacrificial layer was too rough, non-uniform and with a high porosity, so that printing a conductive membrane on top of it was unsuccessful. An alternative solution approach used kapton tape, a polyimide, as movable membrane; experimental characterization has shown that the structure is not properly clamped along its rim, yielding a vibraion at a frequency of 1.1 KHz, when actuated, compared to a resonant frequency of 9.3 KHz achieved by finite element analysis of the CMUT structure. The approach shows enough promise for further investigations, along directions suggested at the end of the thesis.

description: The degree of randomness, or partial order, present in two-dimensional supramolecular arrays of isophthalate tetracarboxylic acids is shown to vary due to subtle chemical changes such as the choice of solvent or small differences in molecular dimensions. This variation may be quantified using an order parameter and reveals a novel phase behaviour including random tiling with varying critical properties as well as ordered phases dominated by either parallel or non-parallel alignment of neighbouring molecules, consistent with long-standing theoretical studies. The balance between order and randomness is driven by small differences in the intermolecular interaction energies, which we show, using numerical simulations, can be related to the measured order parameter. Significant variations occur even when the energy difference is much less than the thermal energy highlighting the delicate balance between entropic and energetic effects in complex self-assembly processes.

description: A prime number $p$ is said to be a Wolstenholme prime if it satisfies the congruence ${2p-1\choose p-1} \equiv 1 \,\,(\bmod{\,\,p^4})$. For such a prime $p$, we establish the expression for ${2p-1\choose p-1}\,\,(\bmod{\,\,p^8})$ given in terms of the sums $R_i:=\sum_{k=1}^{p-1}1/k^i$ ($i=1,2,3,4,5,6)$. Further, the expression in this congruence is reduced in terms of the sums $R_i$ ($i=1,3,4,5$). Using this congruence, we prove that for any Wolstenholme prime, $$ {2p-1\choose p-1}\equiv 1 -2p \sum_{k=1}^{p-1}\frac{1}{k} -2p^2\sum_{k=1}^{p-1}\frac{1}{k^2}\pmod{p^7}. $$ Moreover, using a recent result of the author \cite{Me}, we prove that the above congruence implies that a prime $p$ necessarily must be a Wolstenholme prime. Applying a technique of Helou and Terjanian \cite{HT}, the above congruence is given as the expression involving the Bernoulli numbers.

description: The present paper theoretically investigates magnetoresistance curves in quasiperiodic magnetic multilayers for two different growth directions, namely [110] and [100]. We considered identical ferromagnetic layers separated by non-magnetic layers with two different thicknesses chosen based on the Fibonacci sequence. Using parameters for Fe/Cr multilayers, four terms were included in our description of the magnetic energy: Zeeman, cubic anisotropy, bilinear and biquadratic couplings. The minimum energy was determined by the gradient method and the equilibrium magnetization directions found were used to calculate magnetoresistance curves. By choosing spacers with a thickness such that biquadratic coupling is stronger than bilinear coupling, unusual behaviors for the magnetoresistance were observed: (i) for the [110] case there is a different behavior for structures based on even and odd Fibonacci generations; and more interesting, (ii) for the [100] case we found magnetic field ranges for which the magnetoresistance increases with magnetic field.

description: Recently published crater statistics on the small asteroids 25143 Itokawa and 433 Eros show a significant depletion of craters below approx. 100 m in diameter. Possible mechanisms that were brought up to explain this lack of craters were seismic crater erasure and self armoring of a coarse, boulder covered asteroid surface. While seismic shaking has been studied in this context, the concept of armoring lacks a deeper inspection and an experimental ground truth. We therefore present cratering experiments of glass bead projectiles impacting into granular glass bead targets, where the grain sizes of projectile and target are in a similar range. The impact velocities are in the range of 200 to 300 m/s. We find that craters become fainter and irregular shaped as soon as the target grains are larger than the projectile sizes and that granular craters rarely form when the size ratio between projectile and target grain is around 1:10 or smaller. In that case, we observe a formation of a strength determined crater in the first struck target grain instead. We present a simple model based on the transfer of momentum from the projectile to this first target grain, which is capable to explain our results with only a single free parameter, which is moreover well determined by previous experiments. Based on estimates of typical projectile size and boulder size on Itokawa and Eros, given that our results are representative also for km/s impact velocities, armoring should play an important role for their evolution.

description: Using polarized and unpolarized neutron scattering we show that interstitial Fe in superconducting Fe_{1+y}Te_{1-x}Se_x induces a magnetic Friedel-like oscillation that diffracts at Q_(in-plane)=(1/2,0) and involves >50 neighboring Fe sites. The interstitial >2 mu_B moment is surrounded by compensating ferromagnetic four spin clusters that may seed double stripe ordering in Fe_{1+y}Te. A semi-metallic 5-band model with (1/2,1/2) Fermi surface nesting and four fold symmetric super-exchange between interstitial Fe and two in-plane nearest neighbors largely accounts for the observed diffraction.

description: Let $J$ be an almost complex structure on a 4-dimensional and unimodular Lie algebra $\mathfrak{g}$. We show that there exists a symplectic form taming $J$ if and only if there is a symplectic form compatible with $J$. We also introduce groups $H^+_J(\mathfrak{g})$ and $H^-_J(\mathfrak{g})$ as the subgroups of the Chevalley-Eilenberg cohomology classes which can be represented by $J$-invariant, respectively $J$-anti-invariant, 2-forms on $\mathfrak{g}$. and we prove a cohomological $J-$decomposition theorem following \cite{DLZ}: $H^2(\mathfrak{g})=H^+_J(\mathfrak{g})\oplus H^-_J(\mathfrak{g})$. We discover that tameness of $J$ can be characterized in terms of the dimension of $H^{\pm}_J(\mathfrak{g})$, just as in the complex surface case. We also describe the tamed and compatible symplectic cones respectively. Finally, two applications to homogeneous $J$ on 4-manifolds are obtained.

description: Progress in deep learning methodologies has transformed the landscape of medical image analysis, opening fresh pathways for precise and effective diagnostics. Currently, multi-phase liver CT scans follow a four-stage process, commencing with an initial scan carried out before the administration of intravenous (IV) contrast-enhancing material. Subsequently, three additional scans are performed following the contrast injection. The primary objective of this research is to automate the analysis and prediction of 50% of liver CT scans. It concentrates on discerning patterns of intensity change during the second, third, and fourth phases concerning the initial phase. The thesis comprises two key sections. The first section employs the non-contrast phase (first scan), late hepatic arterial phase (second scan), and portal venous phase (third scan) to predict the delayed phase (fourth scan). In the second section, the non-contrast phase and late hepatic arterial phase are utilized to predict both the portal venous and delayed phases. The study evaluates the performance of two deep learning models, U-Net and U²-Net. The process involves preprocessing steps like subtraction and normalization to compute contrast difference images, followed by post-processing techniques to generate the predicted 2D CT scans. Post-processing steps have similar techniques as in preprocessing but are performed in reverse order. Four fundamental evaluation metrics, including Mean Absolute Error (MAE), Signal-to-Reconstruction Error Ratio (SRE), Peak Signal-to-Noise Ratio (PSNR), and Structural Similarity Index Measure (SSIM), are employed for assessment. Based on these evaluation metrics, U²-Net performed better than U-Net for the prediction of both portal venous (third) and delayed (fourth) phases. Specifically, U²-Net exhibited superior MAE and PSNR results for the predicted third and fourth scans. However, U-Net did show slightly better SRE and SSIM performance in the predicted scans. On the other hand, for the exclusive prediction of the fourth scan, U-Net outperforms U²-Net in all four evaluation metrics. This implementation shows promising results which will eliminate the need for additional CT scans and reduce patients’ exposure to harmful radiation. Predicting 50% of liver CT volumes will reduce exposure to harmful radiation by half. The proposed method is not limited to liver CT scans and can be applied to various other multi-phase medical imaging techniques, including multi-phase CT angiography, multi-phase renal CT, contrast-enhanced breast MRI, and more.

description: Image binarization is the process of separation of pixel values into two groups, white as background and black as foreground. Thresholding plays a major in binarization of images. Thresholding can be categorized into global thresholding and local thresholding. In images with uniform contrast distribution of background and foreground like document images, global thresholding is more appropriate. In degraded document images, where considerable background noise or variation in contrast and illumination exists, there exists many pixels that cannot be easily classified as foreground or background. In such cases, binarization with local thresholding is more appropriate. This paper describes a locally adaptive thresholding technique that removes background by using local mean and mean deviation. Normally the local mean computational time depends on the window size. Our technique uses integral sum image as a prior processing to calculate local mean. It does not involve calculations of standard deviations as in other local adaptive techniques. This along with the fact that calculations of mean is independent of window size speed up the process as compared to other local thresholding techniques.

Creators: name: MARTA MEKONNEN
Publisher: name: Zenodo
Year: 2015

description: Passengers expect and deserve an experience at railway stations, through service, facilities and access, which adds to their end-to-end journey experience. Research shows that integration with others modes, convenient facilities, readily available information and an environment which is pleasant to move around and wait in are significant influences on both the attractiveness of rail and determinants of passenger satisfaction.

In this thesis station platform capacity of Addis Ababa light rail transit for efficient and effective urban transport service provision is examined. This study is designed to help LRT in the development of more secure and capable station, in terms of passenger capacity on platform areas.

The assessment considers LOS (level of service) criteria, which is evaluated in two ways first by evaluating the LOS of long term and initial stage of predicted passenger flow and second evaluation of LOS of the proposed platform by considering unused spaces

title: The Vulnerabilities to the RSA Algorithm and Future Alternative Algorithms to Improve Security
Creators: name: Johnson, James
Publisher: name: Old Dominion University Libraries

description: The RSA encryption algorithm has secured many large systems, including bank systems, data encryption in emails, several online transactions, etc. Benefiting from the use of asymmetric cryptography and properties of number theory, RSA was widely regarded as one of most difficult algorithms to decrypt without a key, especially since by brute force, breaking the algorithm would take thousands of years. However, in recent times, research has shown that RSA is getting closer to being efficiently decrypted classically, using algebraic methods, (fully cracked through limited bits) in which elliptic-curve cryptography has been thought of as the alternative that is stronger than RSA. However, the biggest issue that faces RSA, as well as other cryptographic algorithms, such as elliptic curve, is the development of quantum computing. Mathematically, several algorithms, such as Shor’s algorithm, have been proven to decrypt RSA’s algorithm within a span of hours, using a quantum computer, meaning our security systems are at risk of collapsing. Research needs to address this issue, as security is compromised, and several algorithms have been created to become quantum resistant. Through classical methods (post-quantum cryptography), hash and lattice-based algorithms have used properties of group theory and number theory to create irreversible functions that even a quantum computer would not be able to decrypt. Additionally, the emergence of quantum cryptography has led research towards devising encryption algorithms based on quantum-mechanical properties that would allow for eavesdropping to be detected and for systems to remain secure.

description: Information about the nuclear matter under the extreme conditions of temperature and density and the role of symmetry energy under these conditions is still a topic of crucial importance in the present day nuclear physics research. The multifragmentation, collective flow and the nuclear stopping is among the various rare phenomenon which can be observed in heavy-ion collisions at intermediate energies. The nuclear stopping, which is sensitive towards the symmetry energy has gained a lot of interest because it provides the possibility to examine the degree of thermalization or equilibration in the matter. Aim of the present study is to pin down the nuclear stopping for the different forms of density dependent symmetry energy
Computationally efficient techniques for H.264/AVC transcoding applications
Creators: name: Tang, Qiang
Publisher: name: University of British Columbia

description: Providing universal access to end-users is the ultimate goal of the communications, entertainment and broadcasting industries. H.264/AVC has become the coding choice for broadcasting, and entertainment (i.e., DVD/Blu-ray), meaning that the latest set-top boxes and playback devices support this new video standard. Since many existing videos had been encoded using previous video coding standards (e.g., MPEG-2), playing them back on the new devices will be possible only if they are converted or transcoded into the H.264/AVC format. In addition, even in the case that videos are compressed using H.264/AVC, transmitting them over different networks for different user applications (e.g., mobile phones, TV) will require transcoding in order to adapt them to different bandwidth and resolution requirements. This thesis tackled the H.264/AVC transcoding problems in 3 aspects. At first, we propose the algorithms that improve the resultant video quality of the transform-domain MPEG-2 to H.264/AVC transcoding structure. Transform-domain transcoding offers the least complexity. However, it produces transcoded videos suffering from some inherent video distortions. We provide a theoretical analysis for these distortions and propose algorithms that compensate for the distortions. Performance evaluation shows that the proposed algorithms greatly improve the resultant transcoded video quality with reasonable computational complexity. Second, we develop an algorithm that speeds up the process of the pixel-domain MPEG-2 to H.264/AVC transcoding. Motion re-estimation is the most time consuming process for this type of transcoding. The proposed algorithm accelerates the motion re-estimation process by predicting the H.264/AVC block-size partitioning. Performance evaluation shows the proposed algorithm significantly reduces the computational complexity compared to the existing state-of-the-art method, while maintaining the same compression efficiency. At last, we propose the algorithm that accelerates the transcoding process of downscaling a coded H.264/AVC video into its downscaled version using arbitrary downscaling ratios. To accelerate the process of encoding the downscaled video, the proposed algorithm derives accurate initial motion vectors for the downscaled video, thus greatly reducing the computational complexity of the motion re-estimation process. Compared to other downscaling state-of-the-art methods, the proposed method requires the least computation while yields the best compression efficiency.

description: It has been shown that the Virgo spiral galaxy NGC 4330 shows signs of ongoing ram pressure stripping in multiple wavelengths: at the leading edge of the interaction, the Halpha and dust extinction curve sharply out of the disk; on the trailing side, a long Halpha/UV tail has been found which is located upwind of a long HI tail. We complete the multiwavelength study with IRAM 30m HERA CO(2-1) and VLA 6 cm radio continuum observations of NGC 4330. The data are interpreted with the help of a dynamical model including ram pressure and, for the first time, star formation. Our best-fit model reproduces qualitatively the observed projected position, radial velocity of the galaxy, the molecular and atomic gas distribution and velocity field, and the UV distribution in the region where a gas tail is present. However, the observed red UV color on the windward side is currently not reproduced by the model. Based on our model, the galaxy moves to the north and still approaches the cluster center with the closest approach occurring in ~100 Myr. In contrast to other Virgo spiral galaxies affected by ram pressure stripping, NGC 4330 does not show an asymmetric ridge of polarized radio continuum emission. We suggest that this is due to the relatively slow compression of the ISM and the particular projection of NGC 4330. The observed offset between the HI and UV tails is well reproduced by our model. Since collapsing and starforming gas clouds decouple from the ram pressure wind, the UV-emitting young stars have the angular momentum of the gas at the time of their creation. On the other hand, the gas is constantly pushed by ram pressure. The reaction (phase change, star formation) of the multiphase ISM (molecular, atomic, ionized) to ram pressure is discussed in the framework of our dynamical model.
