Equalization and coding for the two-dimensional intersymbol interference channel
Creators: name: Cheng, Taikun
Publisher: name: Washington State University
Year: 2007
Subjects: Signal processing -- Digital techniques

description: This dissertation addresses the problems of detection and error correction for binary data corrupted by two-dimensional (2D) intersymbol interference (ISI) and additive white Gaussian noise (AWGN). The 2D-ISI channel occurs in proposed next-generation optical disk systems and holographic storage systems, which store data in 2D pages, and are subject to 2D-ISI at high data densities. This dissertation presents a novel iterative row-column soft decision feedback algorithm (IRCSDFA) which exchanges weighted soft information between row and column maximum-a-posteriori (MAP) detectors. Each MAP detector exploits soft-decision feedback from previously processed rows or columns. The new algorithm gains about 0.3 dB over the previously best published results for the 2 2 averaging mask. For a non-separable 3 3 mask, the IRCSDFA gains 0.8 dB over a previous soft-input/soft-output iterative algorithm which decomposes the 2D convolution into 1D row and column operations. This dissertation also shows how to adapt the IRCSDFA for non-equiprobable binary sources. And this dissertation proposes an approach to optimize the iteration schedule inside the IRCSDFA by using EXIT charts. This dissertation addresses the error floor problem of low-density parity check (LDPC) codes on the binary-input AWGN channel, by constructing a serially concatenated code consisting of two systematic irregular repeat-accumulate (IRA) component codes connected by an interleaver. The interleaver is designed to prevent stopping-set error events in one of the IRA codes from propagating into those of the other code. Simulations with two 128-bit rate 0.707 IRA component codes show that the proposed architecture achieves a much lower error floor at higher SNRs, compared to a 16384-bit rate 1/2 IRA code, but incurs an SNR penalty of about 2 dB at low to medium SNRs. Experiments indicate that the SNR penalty can be reduced at larger blocklengths. This dissertation also demonstrates an iterative joint detection/decoding scheme for the 2D ISI channel by employing IRCSDFA and LDPC codes. Simulation results show that about 1/3 of the gain achieved by IRCSDFA over the previous best equalization algorithm is retained when the two equalizers are combined with LDPC codes.

description: Griseofulvin is an antifungal polyketide metabolite produced mainly by ascomycetes. Since it was commercially introduced in 1959, griseofulvin has been used in treating dermatophyte infections. This fungistatic has gained increasing interest for multifunctional applications in the last decades due to its potential to disrupt mitosis and cell division in human cancer cells and arrest hepatitis C virus replication. In addition to these inhibitory effects, we and others found griseofulvin may enhance ACE2 function, contribute to vascular vasodilation, and improve capillary blood flow. Furthermore, molecular docking analysis revealed that griseofulvin and its derivatives have good binding potential with SARS-CoV-2 main protease, RNA-dependent RNA polymerase (RdRp), and spike protein receptor-binding domain (RBD), suggesting its inhibitory effects on SARS-CoV-2 entry and viral replication. These findings imply the repurposing potentials of the FDA-approved drug griseofulvin in designing and developing novel therapeutic interventions. In this review, we have summarized the available information from its discovery to recent progress in this growing field. Additionally, explored is the possible mechanism leading to rare hepatitis induced by griseofulvin. We found that griseofulvin and its metabolites, including 6-desmethylgriseofulvin (6-DMG) and 4- desmethylgriseofulvin (4-DMG), have favorable interactions with cytokeratin intermediate filament proteins (K8 and K18), ranging from -3.34 to -5.61 kcal mol(-1). Therefore, they could be responsible for liver injury and Mallory body (MB) formation in hepatocytes of human, mouse, and rat treated with griseofulvin. Moreover, the stronger binding of griseofulvin to K18 in rodents than in human may explain the observed difference in the severity of hepatitis between rodents and human.

description: Nanomedicines are being actively developed as inhalable drug delivery systems. However, there is a distinct utility in developing smaller polymeric systems that can bind albumin in the lungs. We therefore examined the pulmonary pharmacokinetic behavior of a series of lipidated brush-PEG (5 kDa) polymers conjugated to 1C2, 1C12 lipid or 2C12 lipids. The pulmonary pharmacokinetics, patterns of lung clearance and safety of polymers were examined in rats. Permeability through monolayers of primary human alveolar epithelia, small airway epithelia and lung microvascular endothelium were also investigated, along with lung mucus penetration and cell uptake. Polymers showed similar pulmonary pharmacokinetic behavior and patterns of lung clearance, irrespective of lipid molecular weight and albumin binding capacity, with up to 30% of the dose absorbed from the lungs over 24 h. 1C12-PEG showed the greatest safety in the lungs. Based on its larger size, 2C12-PEG also showed the lowest mucus and cell membrane permeability of the three polymers. While albumin had no significant effect on membrane transport, the cell uptake of C12-conjugated PEGs were increased in alveolar epithelial cells. Lipidated brush-PEG polymers composed of 1C12 lipid may provide a useful and novel alternative to large nanomaterials as inhalable drug delivery systems.
The Effect of Unconditional Cash Transfer (UCT) on Household Behavior: Evidence from Iran
Creators: name: Heyrani, Mehrdad
Publisher: name: My University
Year: 2020

description: In 2010, in order to replace energy subsidies, Iran introduced a large Unconditional Cash transfers (UCTs) program providing monthly cash transfers per person in all households that registered for the program. This paper examines the potential effect of this program on household behavior during 2010-2011, based on the difference-in-difference method. The result shows that UCT had no significant effect on total expenditure and investment in rural and urban areas. The results also indicate that UCT has a significant effect on food nutrition security (calories and protein) in urban areas. The result of the UCT impact on fertility behavior estimates the probability of having a newborn child among urban and rural households with different family sizes. The findings of the study based on the Generalized Ordered Logit model indicate that the UCT did not lead to a significant increase in fertility behavior in urban households. However, the program negatively affected fertility behavior in households without a child, but it led to a positive impact on fertility behavior in households with one, two, and three children.

description: An essential element of secure coding in the Java programming language is well-documented and enforceable coding standards. Coding standards encourage programmers to follow a uniform set of guidelines determined by the requirements of the project and organization, rather than by the programmer's familiarity or preference. Once established, these standards can be used as a metric to evaluate source code (using manual or automated processes). The CERT Oracle Secure Coding Standard for Java provides guidelines for secure coding in the Java programming language. The goal of these guidelines is to eliminate insecure coding practices and undefined behaviors that can lead to exploitable vulnerabilities. Applying this standard will lead to higher quality systems that are robust and more resistant to attack. This report documents the portion of those Java guidelines that are related to concurrency.

description: The gravitational entropy and no-hair conjectures seems to predict contradictory future states of our Universe. The growth of the gravitational entropy is associated with the growth of inhomogeneity, while the no-hair conjecture argues that a universe dominated by dark energy should asymptotically approach a homogeneous and isotropic de Sitter state. The aim of this paper is to study these two conjectures. The investigation is based on the Simsilun simulation, which simulates the universe using the approximation of the Silent Universe. The Silent Universe is a solution to the Einstein equations that assumes irrotational, non-viscous, and insulated dust, with vanishing magnetic part of the Weyl curvature. The initial conditions for the Simsilun simulation are sourced from the Millennium simulation, which results with a realistically appearing but relativistic at origin simulation of a universe. The Simsilun simulation is evolved from the early universe (t = 25 Myr) till far future (t = 1000 Gyr). The results of this investigation show that both conjectures are correct. On global scales, a universe with a positive cosmological constant and non-positive spatial curvature does indeed approach the de Sitter state. At the same time it keeps generating the gravitational entropy.

description: Este trabajo propone una lectura de la obra de García Márquez centrada en la historia de Ángela Vicario. Partiendo de la invisibilización a la que es sometida en el relato, se pretende señalar con varios ejemplos la deshumanización de la mujer, en contraste a la exaltación de la masculinidad, que conduce a la configuración de una violencia estructural y simbólica que se manifiesta en un control permanente y directo del cuerpo de la mujer. Dicho control se presenta en relación con la mistificación de la virginidad como el sustento del honor y la validez de la mujer, lo que la mantiene como un objeto, antes que como sujeto. Este análisis se aprovecha para mostrar las contradicciones del relato patriarcal en torno a la masculinidad y sus efectos en la producción de la violencia, con especial atención en la explotación sexual y comercial de niñas, niños y adolescentes. También se analiza la relación de este último fenómeno con la socialización de las relaciones sexuales que produce la pornografía.
description: 2) This chapter proposes a reading of the work of García Márquez focused on the story of Ángela Vicario. Starting from the invisibility to which she is subjected in the story, it is intended to point out several examples of the dehumanization of women. In contrast it is highlighted the exaltation of masculinity, which leads to the configuration of a structural and symbolic violence that is manifested in a permanent and direct control of the woman’s body. Said control is presented in relation to the mystification of virginity as the sustenance of honor and the validity of women, which maintains them as an object, rather than as a subject. This analysis is used to show the contradictions of the patriarchal narrative around masculinity and its effects on the production of violence, with special attention to the sexual and commercial exploitation of children and adolescents. The relationship of this last phenomenon with the socialization of sexual relationships produced by pornography is also analyzed.
A systematic approach to garbage collection for real-time systems
Creators: name: Fu, Wei
Publisher: name: Washington State University
Year: 2007
Subjects: Real-time programming

description: Garbage collection (GC) is becoming increasingly prevalent within the programming
description: landscape. The use of garbage collection in real-time systems has also gained increasing attention given the major advantages in productivity and safety. Unfortunately, the progress in GC for mainstream applications and languages does not solve the problems of memory management for embedded real-time systems. The fundamental problem is that conventional GC techniques do not provide the timing and memory use predictability that are basic real-time program requirements. This dissertation presents a systematic approach to real-time garbage collection (RTGC) for real-time systems. Given a real-time system with a bounded workload, the goal is to calibrate the control of RTGC in a systematic and automatic way. We use an approach that separately models (1) the performance of collector operations and (2) the garbage collection load offered by real-time tasks. It allows prediction of system behavior from knowledge of component behavior and environment specifications. This knowledge provides designers tools to use GC in a predictable way. Three major topics are presented: a system model that outlines the systematic RTGC approach, a GC cost model that guarantees garbage collection activities’ worst-case execution time (WCET), and GC-integrated scheduling and schedulability analysis mechanisms that compute feasible GC execution parameters satisfying real-time timing requirements. A modified Boehm-Demers-Weiser (BDW) GC implemented in Mono 1.1.16, [96], demonstrates the use of the RTGC approach with a status router real-time application.

description: Owing to their integer spin, exciton-polaritons in microcavities can be used for observation of non-equilibrium Bose-Einstein condensation in solid state. However, spin-related phenomena of such condensates are difficult to explore due to the relatively small Zeeman effect of standard semiconductor microcavity systems and the strong tendency to sustain an equal population of two spin components, which precludes the observation of condensates with a well defined spin projection along the axis of the system. The enhancement of the Zeeman splitting can be achieved by introducing magnetic ions to the quantum wells, and consequently forming semimagnetic polaritons. In this system, increasing magnetic field can induce polariton condensation at constant excitation power. Here we evidence the spin polarization of a semimagnetic polaritons condensate exhibiting a circularly polarized emission over 95% even in a moderate magnetic field of about 3 T. Furthermore, we show that unlike nonmagnetic polaritons, an increase on excitation power results in an increase of the semimagnetic polaritons condensate spin polarization. These properties open new possibilities for testing theoretically predicted phenomena of spin polarized condensate.

description: Based on Insight-HXMT data, we report on the pulse fraction evolution during the 2017-2018 outburst of the newly discovered first Galactic ultraluminous X-ray source (ULX) Swift J0243.6+6124. The pulse fractions of 19 observation pairs selected in the rising and fading phases with similar luminosity are investigated. The results show a general trend of the pulse fraction increasing with luminosity and energy at super-critical luminosity. However, the relative strength of the pulsation between each pair evolves strongly with luminosity. The pulse fraction in the rising phase is larger at luminosity below $7.71\times10^{38}$~erg~s$^{-1}$, but smaller at above. A transition luminosity is found to be energy independent. Such a phenomena is firstly confirmed by Insight-HXMT observations and we speculate it may have relation with the radiation pressure dominated accretion disk.

Machine translation literacy

description: Using a lingua franca for scholarly communication offers some advantages, but it also limits research diversity, and there is a growing movement to encourage publication in other languages. Both approaches require scholars to access material through other languages, and more people are turning to machine translation to help with this task. Machine translation has improved considerably in recent years with the introduction of artificial intelligence techniques such as machine learning; however, it is far from perfect and users who are not trained as professional translators need to improve their machine translation literacy to use this technology effectively. Machine translation literacy is less about acquiring techno-procedural skills and more about developing cognitive competencies. In this way, machine translation literacy aligns with the overall direction of the Association of College & Research Libraries’ (2015) Framework for Information Literacy for Higher Education, which encourages a conceptual, rather than a skills-based, approach. This case study presents a pilot project in which machine translation literacy instruction was incorporated into a broader program of information literacy and delivered to first-year students—both Anglophone and non-Anglophone—at a Canadian university. Students were surveyed and, overall, they found the machine translation literacy module to be valuable and recommended that similar instruction be made available to all students. Academic librarians are well-positioned to participate in the delivery of machine translation literacy instruction as part of a broader information literacy program, and in so doing, they can promote linguistic diversity and better enable students and researchers from all regions to participate in scholarly conversations.

description: We deal with the approximate solution of initial value problems in infinite-dimensional Banach spaces with a Schauder basis. We only allow finite-dimensional algorithms acting in the spaces $\rr^N$, with varying $N$. The error of such algorithms depends on two parameters: the truncation parameters $N$ and a discretization parameter $n$. For a class of $C^r$ right-hand side functions, we define an algorithm with varying $N$, based on possibly non-uniform mesh, and we analyse its error and cost. For constant $N$, we show a matching (up to a constant) lower bound on the error of any algorithm in terms of $N$ and $n$, as $N,n\to \infty$. We stress that in the standard error analysis the dimension $N$ is fixed, and the dependence on $N$ is usually hidden in error coefficient. For a certain model of cost, for many cases of interest, we show tight (up to a constant) upper and lower bounds on the minimal cost of computing an $\e$-approximation to the solution (the $\e$-complexity of the problem). The results are illustrated by an example of the initial value problem in the weighted $\ell_p$ space ($1\leq p

The as-grown particles were semi-insulating and showed reflectance spectra characteristic of insulating ionic crystals. Samples annealed in hydrogen showed a significant increase in electrical conductivity and free-carrier ab-sorption. A difference was observed in the reststrahlen line shape of the conductive sample compared to that of the as-grown sample. The effective medium approximation was applied to model the reflectance and absorption spectra. The agreement between the experimental results and the model suggests that the nanoparticles have inhomogeneous carrier concentrations. Exposure to oxygen for several hours led to a significant decrease in carrier concentration, possibly due to the adsorption of negative oxygen molecules on the nanoparticle surfaces. Cu doped ZnO nanoparticles were prepared by using a zinc acetate/copper acetate precursor. The electronic transitions of Cu2+ ions were observed in the IR absorption spectrum at low temperatures. The high resistivity property of ZnO:Cu nanoparticles was observed. Magnesium hydroxide thin layers were formed by a chemical reaction between magnesium nanorods and water. IR spectroscopy showed hydroxide (OH) vibrational modes. The assignment was verified by reactions with heavy water which produced the expected OD vibrational frequency. A Fano interference was detected for hydroxide layers formed on metallic magnesium. For hydroxide layers on insulating magnesium hydride, however, the line shape was symmetric and no Fano resonance was observed. The results show that the hydroxide layer is thin such that the vibrational motion couples to the free electron continuum of the magnesium metal.

description: At the heart of the discipline of History is a conviction that context matters. But there seems to be less and less agreement on how to define the appropriate context for research. National history is having a particularly hard time these days as researchers focus on the changing flows of ideas and people, processes and products, across official geo-political boundaries. But micro history is similarly in trouble for having distracted researchers from the suppos- edly important historical questions or for becoming trivial in comparison to Big History (Guldi/Armitage 2014). At first glance, such developments may appear to complicate rather than clarify metaphysical and epistemological decisions especially for educational historians who have so successfully shown the central importance of mass schooling to the making of modernity. Indeed, such research during the past half-century has played an important role in the re-thinking of the nineteenth and twentieth centuries. Micro histories compellingly analyzed school at- tendance patterns in the context of changing family and community life. National histories revealed how governments embraced schools as projects of state formation. Thematic studies showed how education reflected and inspired changing norms, policies and experiences of class, gender and ethnicity. Taken together, such work along with many other contributions moved educational history from the margins to the mainstream of efforts to understand the profound transformations following the Age of Revolutions.

description: Wie lange klingt kurz? Wie viel ist wenig? Solche Fragen regen an, um experimentierend, vergleichend, interaktiv Antworten zu finden. In dieser Arbeit wird eine Verbindung zwischen Mathematik und Rhythmik hergestellt, die aufzeigt, wie im integrativen Unterricht auf der Kindergarten- und der Unterstufe mittels des Polaritätsprinzips mathematische Kompetenzen gefördert werden können. Das Polaritätsprinzip des gestalterischen Verfahrens Rhythmik wird ausgehend von einer Literaturanalyse durch zehn Kriterien gekennzeichnet. Ebenso werden im Fachbereich Mathematik über Fachliteratur die Grundlagen für die Kriterien zur Förderung mathematischer Kompetenzen erarbeitet. Daraus resultierend wird exemplarisch dargelegt, inwiefern und in Bezug auf welche mathematischen Inhalte am Beispiel des Lehrplans 21 das Polaritätsprinzip der Rhythmik das kompetenzorientierte mathematische Lernen begünstigt.

description: Exendin-4 (Ex4) is a promising drug for diabetes mellitus with a half-life of 2.4 h in human bodies. Besides, the E×4formulations currently employed in the clinic or under development have problems pertaining to stability. In this study, palmitic acid-modified E×4(Pal-Ex4) was prepared and purified to extend the half-life of Ex4. In addition, Pal-Ex4-MVLs were further designed and optimized as a long-acting delivery system for intramuscular injection. Pal-Ex4 was encapsulated within multivesicular liposomes (MVLs) via a two-step double emulsification process. The formulated products were then assessed for their vesicle size, encapsulation efficiency, and in vitro and in vivo. Pal-Ex4-MVLs with a notable encapsulation efficiency of 99.18% were successfully prepared. Pal-Ex4-MVLs, administered via a single intramuscular injection in Sprague-Dawley rats, sustained stable plasma concentrations for 168 h, presenting extended half-life (77.28 ± 12.919 h) and enhanced relative bioavailability (664.18%). MVLs protected E×4through providing stable retention and slow release. This approach considerably improved the in-situ stability of the drug for intramuscular administration. The combination of palmitic acid modification process with MVLs provides dual protection for E×4and can be a promising strategy for other hydrophilic protein/polypeptide-loaded sustained-release delivery systems with high drug bioactivity.

Characterization of microstructure and internal displacement field of sand using X-ray computed tomography
Creators: name: Razavi, Mohammad Reza
Publisher: name: Washington State University

Subjects: Sand -- Microstructure

description: This study presents a systematic method to examine the microstructure characteristics and internal displacement field of sands using X-ray computed tomography (CT) images. The 3-D images of spherical glass beads, Silica sand, and Ottawa sand are characterized using advanced image processing techniques.
description: An interactive computer program is developed to study porosity variation with increasing radius of a spherical volume from the 3-D images of these materials. The porosity variation of Silica sand and Ottawa sand shows three characteristic regions: an initial fluctuation region due to microscopic variations, a constant plateau region, and a region with a monotonic increase/decrease due to heterogeneity. The homogenous medium of glass beads did not show the last region. The results show that for the spherical glass beads the representative elementary volume radius is about 2 to 3 times the average diameter. The radius for Silica sand composed mainly of elongated particles is between 5 to 11 times of d50 and for Ottawa sand composed mainly of subrounded particles is between 9 to 16 times of d50. These values appear to justify the use of 10 to 20 diameters of sand grains adopted in some past studies.

description: A novel triaxial system is designed to facilitate the characterization of the 3-D images of soil microstructure and its evolution nondestructively in real time using X-ray computed tomography while it is subjected to shearing. The system was designed to have a total weight of 500 N, capable to increase the cell pressure up to 400 kPa, and applying up to 10 kN axial load. Moreover, the system is designed to be able to do temperature controlled (-10 to 65 °C) triaxial and uniaxial tests on many different materials, including soil, asphalt concrete, wood, small metal specimens, and composites. The system is fully microprocessor controlled using a workstation outside of the protection cabinet of X-ray CT. Load can be kept constant, or applied either in strain control or stress control.
description: A computer code is developed to determine the internal displacement field in sands by comparing two successive X-ray CT images. The method is an extension of the template matching technique used in image processing for 3-D situations. The program is verified by applying a known displacement or rotation to the reference image. An interactive computer program is developed to find the changes in local porosity distribution within the sand specimen as it is subjected to shearing. The ability to quantify the internal displacement and local porosity would contribute in the characterization of strain localization and shear band development.

Cyclic Mario Worlds -- Color-Decomposition for One-Loop QCD

description: We present a new color decomposition for QCD amplitudes at one-loop level as a generalization of the Del Duca-Dixon-Maltoni and Johansson-Ochirov decomposition at tree level. Starting from a minimal basis of planar primitive amplitudes we write down a color decomposition that is free of linear dependencies among appearing primitive amplitudes or color factors. The conjectured decomposition applies to any number of quark flavors and is independent of the choice of gauge group and matter representation. The results also hold for higher-dimensional or supersymmetric extensions of QCD. We provide expressions for any number of external quark-antiquark pairs and gluons.
