description: The usual action of Yang-Mills theory is given by the quadratic form of curvatures of a principal G bundle defined on four dimensional manifolds. The non-linear generalization which is known as the Born-Infeld action has been given. In this paper we give another non-linear generalization on four dimensional manifolds and call it a universal Yang-Mills action. The advantage of our model is that the action splits {\bf automatically} into two parts consisting of self-dual and anti-self-dual directions. Namely, we have automatically the self-dual and anti-self-dual equations without solving the equations of motion as in a usual case. Our method may be applicable to recent non-commutative Yang-Mills theories studied widely.

Subjects: subject: Earth and Planetary Astrophysics (astro-ph.EP)

description: In this work, we introduce a comet dust model that incorporates multiple dust morphologies along with inhomogeneous mixture of silicate minerals and carbonaceous materials under power-law size distribution, to replicate the standard polarization-phase curve observed in several comets in the narrow-band continuum. Following the results from Rosetta/MIDAS and COSIMA, we create high porosity Hierarchical Aggregates (HA) and low porosity (< 10$\%$) Solids in the form of agglomerated debris. We also introduce a moderate porosity structure with solids in the core, surrounded by fluffy aggregates called Fluffy Solids (FS). We study the mixing combinations, (HA and Solids), (HA and FS) and (HA, FS and Solids) for a range of power-law index n=2.0 to 3.0 for different sets of mixing percentage of silicate minerals and carbonaceous materials. Polarimetry of the short period comets 1P/Halley and 67P/Churyumov-Gerasimenko match best with the polarisation resulting from the combination of HA and Solids while the combinations (HA and FS) and (HA, FS and Solids) provide the best fit results for the long period comets C/1995 O1 (Hale-Bopp) and C/1996 B2 (Hyakutake). The best fit model results also recreate the observed wavelength dependence of polarization. Our dust model agree with the idea that the long period comets may have high percentage of loose particles (HA and FS) compared to those in the case of short period comets as the short period comets experience more frequent and/or higher magnitude of weathering.

description: This thesis argues for two main points concerning the philosophy of natural language semantics. Firstly, that the objects of assertion are distinct from the entities appealed to in the compositional rules of natural language semantics. Secondly, natural languages contain context-shifting operators known as "monsters". In fact, it will be shown that these theses are simply two sides of the same coin. -- provided by Candidate.
Blacks and Jews in the Black Power Movement and Its Subsequent Scholarship

description: The objective of this thesis was to examine the Black-Jewish relationship during the mid-twentieth century as the Black Civil Rights Era transitioned into the Black Power Era (1966-1973) in Baltimore, Maryland.  Another goal was to analyze the scholarship on the topic of Black-Jewish relations during the Black Power Era already produced by other scholars, and determine whether the relationship in Baltimore mirrored or differed from the analysis of the national relationship.  Lastly, the April 1968 riots which followed Dr. Martin Luther King's death serves as a case study of a singular event, which acted as a catalyst for change in the relationship. To analyze the relationship, a heavy reliance was placed on local primary documents, especially the leading print media of both communities in Baltimore, the Afro-American Newspaper and the Jewish Times Magazine.  This is a study of both individuals and organizations as representatives of the Black and Jewish communities in Baltimore, including institutions like the N.A.A.C.P., Urban League, and influential synagogues like Har Sinai and Chizuk Amuno.  Ultimately, the relationship between the Black and Jewish communities in Baltimore did not conclude during the late 1960s, as many national alliances did, but shifted, becoming more nuanced and complicated.
Demystifying Deep Learning in Predictive Spatio-Temporal Analytics: An Information-Theoretic Framework

description: Deep learning has achieved incredible success over the past years, especially in various challenging predictive spatio-temporal analytics (PSTA) tasks, such as disease prediction, climate forecast, and traffic prediction, where intrinsic dependency relationships among data exist and generally manifest at multiple spatio-temporal scales. However, given a specific PSTA task and the corresponding dataset, how to appropriately determine the desired configuration of a deep learning model, theoretically analyze the model's learning behavior, and quantitatively characterize the model's learning capacity remains a mystery. In order to demystify the power of deep learning for PSTA, in this paper, we provide a comprehensive framework for deep learning model design and information-theoretic analysis. First, we develop and demonstrate a novel interactively- and integratively-connected deep recurrent neural network (I$^2$DRNN) model. I$^2$DRNN consists of three modules: an Input module that integrates data from heterogeneous sources; a Hidden module that captures the information at different scales while allowing the information to flow interactively between layers; and an Output module that models the integrative effects of information from various hidden layers to generate the output predictions. Second, to theoretically prove that our designed model can learn multi-scale spatio-temporal dependency in PSTA tasks, we provide an information-theoretic analysis to examine the information-based learning capacity (i-CAP) of the proposed model. Third, to validate the I$^2$DRNN model and confirm its i-CAP, we systematically conduct a series of experiments involving both synthetic datasets and real-world PSTA tasks. The experimental results show that the I$^2$DRNN model outperforms both classical and state-of-the-art models, and is able to capture meaningful multi-scale spatio-temporal dependency.

description: We demonstrate the advantages of randomization in coherent quantum dynamical control. For systems which are either time-varying or require decoupling cycles involving a large number of operations, we find that simple randomized protocols offer superior convergence and stability as compared to deterministic counterparts. In addition, we show how randomization always allows to outperform purely deterministic schemes at long times, including combinatorial and concatenated methods. General criteria for optimally interpolating between deterministic and stochastic design are proposed and illustrated in explicit decoupling scenarios relevant to quantum information storage.

description: This study looks at the meaning of personal possessions in residents' rooms in an assisted living (AL) facility. Ethnographic interviews with nine residents and the admissions coordinator focus on the process of moving from home to assisted living and on object relations within the AL room. Interviews from the study, Social Relations in Residential Settings were also used. Treasured objects act as reflections of the self and of past relationships. Pieces from the past may help an older person remain connected to important events and foster continuity in the person. Autonomy of the elder, especially as it relates to the selection of items to bring to assisted living, is put forth as a moderator of disruptions to self.  Recommendations to families and AL administrators may inform the practical aspects of leaving home.
Role of contact bonding on electronic transport in metal-carbon nanotube-metal systems

description: We have investigated the effects of the interfacial bond arrangement on the electronic transport features of metal-nanotube-metal systems. The transport properties of finite, defect-free armchair and zigzag single-walled carbon nanotubes attached to Au(111) metallic contacts have been calculated by means of the non-equilibrium Green functional formalism with the Tight-Binding and the Extended Huckel Hamiltonians. Our calculations show that the electrode material is not the only factor which rules contact transparency. Indeed, for the same electrode, but changing nanotube helicities, we have observed an overall complex behaviour of the transmission spectra due to band mixing and interference. The comparison of the two models shows that the Tight Binding approach fails to give a satisfactory representation of the transmission function when a more accurate description of the C-C and Au-C chemical bonds has to be considered. We have furthermore examined the effect of interface geometry variance on conduction and found that contact-nanotube distance has a significant impact, while contact-nanotube symmetry plays a marginal, yet evident role.

description: We show that zonal flow can be preferentially excited by intermediate-scale toroidal electron temperature gradient (ETG) turbulence in tokamak plasmas. Previous theoretical studies that yielded an opposite conclusion assumed a fluid approximation for ETG modes. Here, we carry out a gyrokinetic analysis which ultimately yields a nonlinear Schrödinger equation for the ETG dynamics with a Navier-Stokes type nonlinearity. For typical tokamak parameters, it is found that zonal flow generation plays an important role in the intermediate-scale ETG turbulence. This finding offers an explanation for recent multi-scale gyrokinetic simulations.

description: Title of Thesis: American Jews and the Holocaust: History, Memory and Identity Eliana Michelle Ginsburg, Master of Historical Studies, 2009 Thesis Directed By: Dr. Denise Meringolo, Assistant Professor of History, Department of History Formation of American Jewish identity in the 1930s and 1940s was a multi-dimensional process.  The Jewish American experience in the United States is unique because they faced a moral dilemma of loyalties and ties. They felt an obligation and responsibility to save their European brethren but were prevented from presenting a cohesive voice to protest the annihilation of Europe's Jews in the Holocaust.  Examining American Jews' struggles with anti-Semitism, assimilation and ultimately the Holocaust, makes evident the complex process of immigrant identity formation in the United States and illuminates the specific ways in which the Jewish immigrant experience is unique. This thesis project will interpret oral history interviews from Jewish Americans who dealt with conflicting identities as Jews and as Americans.  By creating a website that integrates oral history interviews with photographs and themes drawn from relevant scholarship, this project will be an opportunity for high school history teachers to begin a dialogue with students discussing issues around the Holocaust and the moral dilemma Jewish Americans faced being Americans yet wanting to aid their European religious brethren. The collection of these oral histories is crucial because they can help students discuss more openly the contradictions and conflicts underlying American Jewish identity. The website will ask thought provoking questions to lead students to a better understanding of the historical limitations that shaped American Jewish identity during the interwar years. The questions will be based on Jewish identity, anti-Semitism and Holocaust awareness.  Creating a website to begin this dialogue will encourage a broader range of viewers to access the information. The website is a pilot, designed to encourage educators and other institutions to add additional and relevant information that can further the discussion. More broadly, this overall project can provide a first step in a larger dialogue to foster understanding of how global and domestic misconceptions can deter a population from aiding victims of a religious genocide.

description: Among exoplanets, the small-size population constitutes the dominant one, with a diversity of properties and compositions ranging from rocky to gas dominated envelope. While a large fraction of them have masses and radii similar to or smaller than Neptune, yet none share common properties in term of orbital period and insulation with our ice giants. These exoplanets belong to multi-planet systems where planets are closely packed within the first tenth of AU and often exposed to strong irradiation from their host star. Their formation process, subsequent evolution, and fate are still debated and trigger new developments of planet formation models. This paper reviews the characteristics and properties of this extended sample of planets with radii between $\sim$ 1.6 and 4.0$_\oplus$. Even though we still lack real Neptune/Uranus analogues, these exoplanets provide us with key observational constraints that allow the formation of our ice giants to be placed in a more general framework than the sole example of our solar system.

Refined isogeometric analysis for generalized Hermitian eigenproblems

Publisher: name: arXiv
Year: 2020
Subjects: subject: Numerical Analysis (math.NA)

description: We use the refined isogeometric analysis (rIGA) to solve generalized Hermitian eigenproblems $({Ku=λMu})$. The rIGA framework conserves the desirable properties of maximum-continuity isogeometric analysis (IGA) discretizations while reducing the computation cost of the solution through partitioning the computational domain by adding zero-continuity basis functions. As a result, rIGA enriches the approximation space and decreases the interconnection between degrees of freedom. We compare computational costs of rIGA versus those of IGA when employing a Lanczos eigensolver with a shift-and-invert spectral transformation. When all eigenpairs within a given interval ${[λ_s,λ_e]}$ are of interest, we select several shifts ${σ_k\in[λ_s,λ_e]}$ using a spectrum slicing technique. For each shift $σ_k$, the cost of factorization of the spectral transformation matrix ${K-σ_k M}$ drives the total computational cost of the eigensolution. Several multiplications of the operator matrices ${(K-σ_k M)^{-1} M}$ by vectors follow this factorization. Let $p$ be the polynomial degree of basis functions and assume that IGA has maximum continuity of ${p-1}$, while rIGA introduces $C^0$ separators to minimize the factorization cost. For this setup, our theoretical estimates predict computational savings to compute a fixed number of eigenpairs of up to ${O(p^2)}$ in the asymptotic regime, that is, large problem sizes. Yet, our numerical tests show that for moderately-sized eigenproblems, the total computational cost reduction is $O(p)$. Nevertheless, rIGA improves the accuracy of every eigenpair of the first $N_0$ eigenvalues and eigenfunctions. Here, we allow $N_0$ to be as large as the total number of eigenmodes of the original maximum-continuity IGA discretization.

This paper reports the results of Multispectral(Landsat-7 ETM+) and Hyperspectral DAIS)data in which multi-class SVMs are compared with maximum likelihood and artificial neural network methods in terms of classification accuracy. Our results show that the SVM achieves a higher level of classification accuracy than either the maximum likelihood or the neural classifier, and that the support vector machine can be used with small training datasets and high-dimensional data.

description: For the purpose of analyzing observed phenomena, it has been convenient, and thus far sufficient, to regard gravity as subject to the deterministic principles of classical physics, with the gravitational field obeying Newton's law or Einstein's equations. Here we treat the gravitational field as a quantum field and determine the implications of such treatment for experimental observables. We find that falling bodies in gravity are subject to random fluctuations ("noise") whose characteristics depend on the quantum state of the gravitational field. We derive a stochastic equation for the separation of two falling particles. Detection of this fundamental noise, which may be measurable at gravitational wave detectors, would vindicate the quantization of gravity, and reveal important properties of its sources.

Cavitand-based molecular hosts: hemicarceplexes, double carceplexes and large carceplexes
Creators: name: Chopra, Naveen
Publisher: name: University of British Columbia
Year: 2009

description: This thesis discusses the synthesis and study of molecular hosts derived from cavitand molecules, and is divided into two parts. Part I of this thesis presents a study of template effects on the formation of hemicarceplex 25»guest from triol cavitand 24. Competition experiments using various guest molecules revealed that the driving forces for the formation of hemicarceplex 25 are the same as those for the formation of previously studied carceplex 23 from tetrol cavitand 22. Part II of the thesis describes the design, synthesis and study of larger closed surface molecular hosts derived from cavitands. A survey of the literature revealed very few examples of molecular receptors having both closed surfaces and large cavities. Chapter 4 outlines the various strategies used in the attempted synthesis of a large "super-carceplex" and the synthesis of several new compounds such as cyclic trimer 135, and cyclic tetramer 136 are described. The final chapter of Part II discusses the uses of cyclic trimer 135 and cyclic tetramer 136 for the creation of novel hosts. Bis-carceplex 137»2pyrazines, a dumbell-shaped molecule comprised of two covalently linked carceplexes, was synthesized from cyclic tetramer 136 in 74% yield and the dynamics of this host molecules (137) were studied via variable temperature ] H NMR spectroscopy and MM2 calculations. The structurally related bis-complex 138#2guests was also formed from cyclic tetramer 138, and guest binding studies of the bis-complex (138) are presented. Cyclic trimer 135 was used to create trimer-carceplex 143#3DMF in 36% yield, demonstrating the unprecedented incarceration of three guest molecules within a carceplex. Variable temperature NMR and FT-IR spectroscopy measurements on trimer-carceplex 143»3DMF revealed unique properties of the incarcerated DMF guests as compared to the bulk DMF solvent, and MM2 calculations suggested a preferred orientation of the guest molecules within the capsule.

description: We discuss the relation between singularities of correlation functions and causal properties of the bulk spacetime in the context of the AdS/CFT correspondence. In particular, we argue that the boundary field theory correlation functions are singular when the insertion points are connected causally by a bulk null geodesic. This implies the existence of "bulk-cone singularities" in boundary theory correlation functions which lie inside the boundary light-cone. We exhibit the pattern of singularities in various asymptotically AdS spacetimes and argue that this pattern can be used to probe the bulk geometry. We apply this correspondence to the specific case of shell collapse in AdS/CFT and indicate a sharp feature in the boundary observables corresponding to black hole event horizon formation.

Subjects: Strike, Trade Union in Nigeria, International labour organization, right to strike in Nigeria, and Nigeria Trade Disputes Act

description: The right to strike is an integral part of the right of workers to associate with other persons to form or join trade unions for the advancement or protection of their interests. This paper examines the basic provision of the extent to which the right to go on strike by trade unions in Nigeria is absolute under various enactments. The paper further examines and reviews the right to strike in some selected jurisdictions. The relevant constitutional provisions entrenching the fundamental right of freedom of association as well as the provisions of other national and international legal instruments which guarantee the right to strike were discussed in full detail. Furthermore, this paper examines the rationale for the ban on strikes in essential services. It also examines the conditions which workers who are not engaged in the provision of essential services must fulfill before they can embark on lawful strikes. These conditions are examined in the light of international labour standards.  The paper contained different types of strikes, the steps trade unions follow before going on strike, the right to strike by the trade union, and different schools of thought as regard to trade unions in Nigeria going on strike

description: This study utilizes a mixed methods approach to examining the cigarette smoking habits and attitudes of undergraduate college students.  It was hypothesized that smokers would have fewer negative attitudes toward cigarette smoking than nonsmokers, that men would be more likely to smoke cigarettes and to have fewer negative attitudes toward cigarette smoking than women, and that when controlling for gender and age, smokers would still have fewer negative attitudes than nonsmokers.  A quantitative pencil-and-paper survey was administered to 326 undergraduate students at a southern university.  A multivariate analysis was used to predict scores on the Cigarette Smoking Attitude Index (Cronbach's Alpha= .897).  Qualitative focus groups comparing cigarette smokers to nonsmokers were also used in this study.  Smokers and men had fewer negative attitudes toward smoking than nonsmokers and women, respectively.  Nonsmokers had more exposure to life threatening health conditions caused by cigarette smoking.

The calculations start 1\,Gyr ago and continue for 100Myr into the future. In this time frame, we simulate how asteroids (and planets) are ejected from the star's vicinity and settle in an Oort cloud and how they escape the local stellar gravity to form tidal steams. A fraction of 0.0098 to 0.026 of the asteroids remain bound to their parent star. The orbits of these asteroids isotropizes and circularizes due to the influence of the Galactic tidal field to eventually form an Oort cloud between 10^4 and 2 10^5au. We estimate that 6% of the nearby stars may have a planet in its Oort cloud. The majority of asteroids (and some of the planets) become unbound from the parent star to become free floating in the Galactic potential. These soli lapides remain in a similar orbit around the Galactic center as their host star, forming dense streams of rogue interstellar asteroids and planets. The Solar system occasionally passes through such tidal streams, potentially giving rise to occasional close encounters with object in this stream. The two recently discovered objects, 1I/(2017 Q3) 'Oumuamua and 2I/(2019 Q4) Borisov, may be such objects. Although the direction from which an individual solus lapis originated cannot easily be traced back to the original host, multiple such objects coming from the same source might help to identify their origin. At the moment the Solar system is in the bow or wake of the tidal stream of 10 of the nearby stars which might contribute considerably to the interaction rate. (abridged)

description: We consider the collision model of Ziman {\em et al.} and study the robustness of $N$-qubit Greenberger-Horne-Zeilinger (GHZ), W, and linear cluster states. Our results show that $N$-qubit entanglement of GHZ states would be extremely fragile under collisional decoherence, and that of W states could be more robust than of linear cluster states. We indicate that the collision model of Ziman {\em et al.} could provide a physical mechanism to some known results in this area of investigations. More importantly, we show that it could give a clue as to how $N$-partite distillable entanglement would be relatively rare in our macroscopic classical world.

description: Understanding the ways that plants can tolerate drought and salinity is necessary to develop plants that can grow on potential agricultural lands that are otherwise non-productive. The expression of a broad spectrum of genes is thought to be regulated by exposure to environmental salinity and water-deficit stress, the major stresses of plants in arid regions. Plant responses to salt and to drought stress have much in common. Both of these stresses reduce the ability of the plants to take up water and this quickly causes reduction in plant growth rate. The overall goal of this project was to identify proteins involved in response to drought and salinity stress in tomato. Combined proteomic approaches, two dimensional gel electrophoresis (2 DE) and liquid chromatography mass spectrometry (LC-MS/MS), revealed the plasticity of gene expression by protein analysis during environmental stress. Tomato plants were exposed to various concentrations of salt (sodium chloride) and polyethylene glycol induced drought stress. Roots and mature leaves were collected at various time points post-treatments, and these tissues were subjected to two-dimensional gel electrophoresis.  A computer image analysis software program, PDQuest (Bio-Rad) was applied to the 2 DE gels for detection of stained proteins, background subtraction and signal matching between treated and control samples. Following completion of the PDQuest analysis, specifically repressed and induced proteins were identified from control and treated tissues using tandem mass spectrometry. The systematic proteomic approaches led to the identification of 150 proteins (induced and repressed) from drought and salt stressed tomato plants. Of the 150 proteins identified, 35 spots/proteins were common to salt and drought stress. These 150 proteins fall into several functional categories that include transcription factors, protein kinases involved in signal transduction, enzymes involved in solute accumulation and water homeostasis, and stress tolerance proteins. Moreover, the induction of several similar proteins during salt and drought stress could indicate some degree of overlap or cross-talk between various signaling pathways during drought and salinity.  Identification of a ""tomato stress proteome"" could lead to enhancement of drought/salinity stress tolerance in tomatoes through genetic manipulation.

description: Ultrasoft colloidal particle fluctuates due to its flexibility. Such fluctuation is essential for colloidal structure and dynamics, but is challenging to quantify experimentally. We use dendrimers as a model system to study the fluctuation of ultrasoft colloids. By considering the dynamic polydispersity in the small-angle neutron scattering (SANS) model, and introducing the fluctuation of invasive water into the contrast in SANS, we reveal the fluctuating amplitudes of the size and shape of the dendrimer of generation 6 at finite concentrations. The size fluctuation is suppressed while the shape fluctuation increases as the weight fraction of dendrimers passes 11%. With neutron spin echo data, we suggest that such crossover originates from the competition between the inter- and intra-particle dynamics. Further investigation on lower-generation samples shows a contrary result, which suggests a structural basis for these dynamic phenomena.

American Bastille? Fort McHenry and Civil Liberty, 1861 - 1862

description: Fort McHenry was the key to holding Baltimore and Maryland in the Union during the Civil War. ""American Bastille? Fort McHenry and Civil Liberty, 1861 - 1862"" is a survey of the critical period April 1861 - May 1862 and the specific role Fort McHenry played in the events surrounding the suspension of habeas corpus, the imposition of martial law, the occupation of Baltimore, and the arrest and detention of 260 American citizens and foreign nationals, many, if not all, of whom would never be formally charged with or tried for a crime.  While a massive strengthening program carried out at Fort McHenry transformed it into the hub of all Federal activity in and around Baltimore, at no time during the first fourteen months of the war did the prison structure at Fort McHenry evolve to operate adequately. The only truly efficient aspect about Fort McHenry's role as a prison is that it was faithfully supplied with occupants.  Where residence is known, the majority of prisoners of state detained at Fort McHenry between May 1861 and May 1862 hailed from Baltimore. Freedom was precarious, and imprisonment was as simple as the will of an army officer, but obtaining release was much more difficult; six loyal merchant seamen were detained for almost two years. Abuses of authority occurred with fearful regularity at the lowest level of military administration. Each resident of Baltimore and Maryland held life, liberty and property at the will and pleasure of the army officers at Fort McHenry.
Constraining hybrid inflation models with WMAP three-year results

description: We reconsider the original model of quadratic hybrid inflation in light of the WMAP three-year results and study the possibility of obtaining a spectral index of primordial density perturbations, $n_s$, smaller than one from this model. The original hybrid inflation model naturally predicts $n_s\geq1$ in the false vacuum dominated regime but it is also possible to have $n_s<1$ when the quadratic term dominates. We therefore investigate whether there is also an intermediate regime compatible with the latest constraints, where the scalar field value during the last 50 e-folds of inflation is less than the Planck scale.

description: Understanding the complex chemistry of functional nanomaterials is of fundamental importance. Controlled synthesis and characterization at the atomic level is essential to gain deeper insight into the unique chemical reactivity exhibited by many nanomaterials. Cerium oxide nanoparticles have many industrial and commercial applications,resulting from very strong catalytic, pro-and anti-oxidant activity. However, the identity of the active species and the chemical mechanisms imparted by nanoceria remain elusive, impeding the further development of new applications. Here, we explore the behavior of cerium oxide nanoparticles of different sizes at different temperatures and trace the electronic structure changes by state-of-the-art soft and hard X-ray experiments combined with computational methods. We confirm the absence of the Ce(III) oxidation state at the surface of CeO2nanoparticles, even for particles as small as 2 nm. Synchrotron X-ray absorption experiments at Ce L3and M5edges, combined with X-ray diffraction (XRD), high-resolution transmission electron microscopy (HRTEM) and small angle X-ray scattering (SAXS) and theoretical calculations demonstrate that in addition to the nanoceria charge stability, the formation of hydroxyl groups at the surface profoundly affects the chemical performance of these nanomaterials
