description: In this work, an agar-graphene oxide hydrogel was prepared to adsorb Cd (II) and Methyl Violet (MV) from water. The hydrogel was synthesised and characterised through SEM and EDS. Kinetic, equilibrium and regeneration studies were carried out, in which Langmuir, Freundlich and Sips isotherm models were fitted to the equilibrium experimental data; and regarding the kinetics, studies were conducted by modelling experimental data considering both empirical and phenomenological models. SEM and EDS have shown the composite present a 3D-disordered porous microstructure and that it is mainly constituted of C and O. Sips model fitted well to Cd (II) (R2 = 0.968 and χ2 =  0.176) and MV (R2 = 0.993 and χ2 =  0.783). The qmax values for MV and Cd (II) were 76.65 and 11.70 mg.g−1, respectively. Pseudo-order models satisfactorily described Cd (II) and MV adsorption kinetics with R2 > 0.90. Regeneration experiments revealed an outstanding reuse capacity of the adsorbent after three cycles of adsorption–desorption for both Cd (II) and MV. This study evidences the possibility of a feasible adsorbent for Cd (II) and MV removal from water for successive cycles of use.

We show that gamma(*)p and gamma(*) gamma(*) elastic amplitudes must include the complex-j plane singularities associated with hadronic elastic amplitudes, and give the characteristics of possible new singularities. We also show that several different models of hadronic total cross sections can be used to predict the LEP data from the HERA measurements.

description: Soil fulfills vital functions for life on Earth and so, just like water and air, its protection from all sources of contamination is a major concern. However, the extensive use of petroleum derived products, either as energy sources or as commodities, lead to important environmental liabilities. Ex-situ soil washing is a technology to concentrate contaminants, allowing soil cleaning and the reuse of extracted petroleum derived products. This work focuses on the optimization of ex-situ soil washing process using surfactants, introducing an evaluation of the washing solution recycling and its after use safe disposal, promoting the reduction of raw materials, energy and water resources costs. Two surfactants, sodium dodecyl sulfate (SDS) and polyoxyethylene sorbitan monooleate (Tween 80), were tested in the decontamination of an artificially contaminated soil with engine lubricant oil waste. The optimization of the washing conditions, such as stirring speed, liquid-solid ratio, number of washing stages, surfactant concentration, was carried out using a Design of Experiments Software, so that the maximum extraction efficiency of Total Petroleum Hydrocarbons (TPH) was achieved. A TPH removal efficiency of (80.7 ± 3.2)% was obtained with Tween 80 after 5 hours of washing and (90.7 ± 2.8)% with SDS after 2 hours at 200 rpm on an orbital shaker with a liquid to solid ratio (L/S) of 15. The potential for reuse of the washing solutions was evaluated. Finally, the discharge of the washing solution was considered using activated carbon to remove the surfactants and ensure its safe disposal.

description: The three ways of generalization of canonical coherent states are briefly reviewed and compared with the emphasis laid on the (minimum) uncertainty way. The characteristic uncertainty relations, which include the Schroedinger and Robertson inequalities, are extended to the case of several states. It is shown that the standard SU(1,1) and SU(2) coherent states are the unique states which minimize the second order characteristic inequality for the three generators. A set of states which minimize the Schroedinger inequality for the Hermitian components of the su_q(1,1) ladder operator is also constructed. It is noted that the characteristic uncertainty relations can be written in the alternative complementary form.

The Development and Validation of the Workplace Racial Microaggression Scale for Asians and Asian Americans (WRMS-AAA)

description: In this dissertation, I developed and validated the workplace racial microaggressions scale for Asians and Asian Americans, WRMS-AAA. This new scale measured the frequency of general and stereotype-based microaggressions that Asians experience in the workplace. General microaggressions are subtle forms of discrimination that could pertain to other minority groups, whereas stereotype-based microaggressions are subtle forms of discrimination that are based on stereotypes of Asians. In Phase 1, items were generated based on extant literature. These items were refined based on the feedback provided by subject matter experts who rated these items on relevancy, clarity, and provided other open-ended feedback. In phases 2 through 5, 351 participants completed a battery of measures including the WRMS-AAA and other measures to assess convergent, discriminant, and concurrent validity. These participants were then randomly split into two sample groups. In phase 2, an exploratory factor analysis using data from sample one (n = 180) revealed a four-factor structure for the WRMS-AAA. Two of these factors were general microaggressions, mistaken identity and not recognized, and the other two factors were stereotype-based microaggressions, ascription of math competency and submissiveness and lacking communication skills. In phase 3, using data from sample 2 (n=171) a confirmatory factor analysis provided further support for the four-factor structure. Both samples provided good internal consistency. In phase 4, the two samples were combined to examine the convergent and discriminant validity of the WRMS-AAA. The WRMS-AAA was highly related to the Workplace Incivility Scale (Cortina et al., 2013) and the Racial and Ethnic Microaggressions Scale (Nadal, 2011), providing support for convergent validity. There was little to no correlation between the WRMS-AAA and social desirability, and there was a weak positive correlation between the WRMS-AAA and neuroticism, providing support for discriminant validity. In phase 5, the WRMS-AAA was correlated with organizational outcomes. The WRMS-AAA was negatively correlated with organizational support, commitment, and job satisfaction. Additionally, the WRMS-AAA was positively correlated with intention to quit and burnout. These correlations provided evidence of concurrent validity, further establishing the validity of the WRMS-AAA. Subtle forms of discrimination are different from explicit discrimination, in that they can be elusive. The WRMS-AAA is one of the only known scales to measure the general and specific subtle forms of discrimination in the workplace. Results and implications of this research are discussed.

description: The process of exclusive electroproduction of vector quarkonium (EEQ), $e p\to epV$, is per se an interesting topic in studies of quarkonium production mechanism, QCD description of diffractive interaction and nucleon structure. We investigate this process in the framework of nonrelativistic QCD and QCD collinear factorization at the next-to-leading order QCD accuracy. The perturbative convergence behavior is discussed in a large range of photon virtuality $Q^2$. The $J/ψ$ large-$Q^2$ electroproduction data at HERA can be well explained, and the $Υ$ differential production rate is predicted. The uncertainties in theoretical predictions with radiative corrections are greatly reduced. Notice the EEQ process is extremely sensitive to the gluon distribution in nucleon, the generalized parton distribution, our results will constraint the gluon density with high precision while confronting to the future experimental data. For the sake of comparing convenience, the analytic expressions are provided.

description: The purpose of this study is to develop and evaluate a scale that measures gender role construction and the various components associated with this process in men of color (i.e., African American, Latinx, and Asian American men). Existing psychological models for understanding this paradigm have primarily focused on the experiences and worldviews of White, Euro-American men without taking into consideration the various societal influences and socializing agents that uniquely impact this process in men of color. In an attempt to more accurately capture this process in people of color, through qualitative data, Miville, Bratini, Corpus, Lau, and Redway (2013) developed the Multicultural Gender Roles Model, which described eight unique components people of color may experience in their gender roles negotiation. For this study, the Multicultural Gender Roles Model (MGRM) was adapted for the development of the Multicultural Gender Roles Scale – Male Version (MGRS – Male Version). Qualitative research from the MGRM and feedback from experts in gender/gender roles research contributed to the development of 69 items that were analyzed through an exploratory factor analysis resulting in a 41-item measure. Exploratory factor analysis of data from 200 men of color resulted in 5 factors reflecting experiences men of color undergo in the gender role development process: (a) Transforming Self-Perceptions, (b) Negative Psychological Symptomatology, (c) Understanding Impact on Others in Family, Community, and Society, (d) Intersecting Identities, and (e) Navigating Emotions related to Privilege and Oppression.

description: Waste light-emitting diodes (LEDs) contain rare and precious metals which has attracted wide attention due to the resource importance. In this study, the experimental research was conducted on the separation and recycling of Au and Ag from LEDs. Firstly, thermal treatment and sieving were conducted to separate and enrich the metals in LEDs. With the constant heating rate of 10°C/min to 450°C under air atmosphere, the metals could be effectively separated from organics and the rare metal Au, Ag mainly concentrates in particles with diameter ≤600 μm, whose concentration is about 1816 mg/kg and 1429 mg/kg respectively. Then, a mix-acid system of HCl-CH3COOH was introduced to recover Au and Ag from the enriched sample. Results show that HCl-CH3COOH system could effectively leach Au and Ag, and the leaching performance of Au and Ag can reach 95.4% and 96.2% respectively under the recommended condition (total acid concentration 5 mol/L, HCl:CH3COOH = 4:1, leaching temperature 80°C, solid-liquid ratio 1:100, leaching time 5 h). The study can provide a new option for waste LEDs recycling, which also provides a more environment friendly method for Au and Ag leaching from industrial waste.

description: A series of cerium-based high-entropy oxide catalysts (the ratio of CeO2 and HEO is 1:1) was prepared by a solid-state reaction method, which exploit their unique structural and performance advantages. The Ce-HEO-T samples can achieve 100% toluene conversion rate above 328°C when they were used as catalysts directly. Subsequently, the Ce-HEO-500 exhibited the lowest temperature for toluene oxidation was used as a support to deposit different amounts of Au for a further performance improvement. Among all of prepared samples, Au/Ce-HEO-500 with a moderate content of Au (0.5 wt%) exhibited the lowest temperature for complete combustion of toluene (260°C), which decreased nearly 70°C compared with Ce-HEO-500 support. Moreover, it also showed excellent stability for 60 h with 98% toluene conversion rate. Most importantly, under the condition of 5 vol.% H2O vapour, the toluene conversion rate remained unchanged and even increased slightly compared with that in dry air, exhibiting excellent water resistance. Combined with the characterizations of XRD, SEM, TEM, BET, Raman, H2-TPR and XPS, it was found that the high dispersion of active Au NPs, the special high-entropy structure and the synergistic effect between Au and Ce, Co, Cu are the key factors when improving the catalytic performance in the Au/Ce-HEO-500 catalyst.
The Development and Application of a New Approach to the Rapid Synthesis of Polypropionate Stereotriads
Creators: Foley, Corinne N.
Publisher: name: Columbia University
Year: 2015
Subjects: Chemistry, Organic

description: The construction of polypropionate stereotriads in the synthesis of many non-aromatic polyketide natural products has typically been achieved through the "Roche ester" approach. This process starts with one of the stereocenters purchased as the Roche ester, followed by multiple redox and protecting group manipulations and only one carbon-carbon bond-forming aldol or crotylation reaction to attain the other two stereocenters of the stereotriad. Motivated by a desire for a more direct and rapid synthesis of these stereotriad constructs, we have built upon previous group methodology to develop a new approach utilizing a three step sequence of alkyne silylformylation-crotylation-Tamao oxidation. This strategy was first utilized in the synthesis of the C1-C9 fragment of the epothilones, and then this route applied to the synthesis of a C6 methyl-modified analog of epothilone B. We have also pursued the synthesis of versatile polypropionate building blocks as a way of generalizing our new approach.

description: Research in Artificial Intelligence (AI) has focused mostly on two extremes: either on small improvements in narrow AI domains, or on universal theoretical frameworks which are usually uncomputable, incompatible with theories of biological intelligence, or lack practical implementations. The goal of this work is to combine the main advantages of the two: to follow a big picture view, while providing a particular theory and its implementation. In contrast with purely theoretical approaches, the resulting architecture should be usable in realistic settings, but also form the core of a framework containing all the basic mechanisms, into which it should be easier to integrate additional required functionality. In this paper, we present a novel, purposely simple, and interpretable hierarchical architecture which combines multiple different mechanisms into one system: unsupervised learning of a model of the world, learning the influence of one's own actions on the world, model-based reinforcement learning, hierarchical planning and plan execution, and symbolic/sub-symbolic integration in general. The learned model is stored in the form of hierarchical representations with the following properties: 1) they are increasingly more abstract, but can retain details when needed, and 2) they are easy to manipulate in their local and symbolic-like form, thus also allowing one to observe the learning process at each level of abstraction. On all levels of the system, the representation of the data can be interpreted in both a symbolic and a sub-symbolic manner. This enables the architecture to learn efficiently using sub-symbolic methods and to employ symbolic inference.

description: The impacts of international emigration and remittances on incomes and poverty in sending areas are increasingly studied with household survey data. But comparing households with and without emigrants is complicated by a triple-selectivity problem: first, households self-select into emigration; second, in some emigrant households everyone moves while others leave members behind; and third, some emigrants choose to return to the origin country. Allowing for duration-dependent heterogeneity introduces a fourth form of selectivity—one must now worry not just about whether households migrate, but also when they do so. This paper clearly sets out these selectivity issues and their implications for existing migration studies, and then addresses them by using survey data designed specifically to take advantage of a randomized lottery that determines which applicants to the over-subscribed Samoan Quota may immigrate to New Zealand. The analysis compares incomes and poverty rates among left behind members in households in Samoa that sent Samoan Quota emigrants with those for members of similar households that were unsuccessful in the lottery. Policy rules control who can accompany the principal migrant, providing an instrument to address the second selectivity problem, while differences among migrants in which year their ballot was selected allow for estimation of duration effects. The authors find that migration reduced poverty among former household members, but they also find suggestive evidence that this effect may be short-lived as both remittances and agricultural income are negatively related to the duration that the migrant has been abroad.

The Development of Cyclobutenone, and Other Work
Creators: Ross, Audrey Graham
Publisher: name: Columbia University
Year: 2012
Subjects: Chemistry

description: This dissertation describes projects falling into two general programs. The first three chapters detail work centered around the peculiar small molecule cyclobutenone. A practical preparation of this previously inaccessible compound is reported. This allowed exploration of applied and academic questions. Cyclobutenone was seen to break from classical patterns due to its extreme inherent strain, polarization, and other factors. These unique properties were harnessed toward enhanced dienophilicity and endo directivity in Diels-Alder reactions. Intramolecular Diels-Alder (IMDA) reactions are described in the second chapter. Cyclobutenone and larger cycloalkenone substrates again diverged in reactivity and selectivity. Lewis acid catalysis reduced this gap to give high levels of endo addition across the series. This stereochemical information was then translated to trans hydrindene junctions by controlled fragmentation of erstwhile dienophile moieties. Observations within these two projects inspired the idea discussed in the third chapter. Here the groundwork is laid out for substitution of cyclobutenone to modulate its properties and carry functionality. In an early example, certain halogenation patterns are shown to further activate cyclobutenone as a dienophile, as well as provide a reactive handle to diversify the possible structures originating from a cyclobutenone core. The last chapter describes two total synthesis projects and their connection. A group of resveratrol-based natural products and analogs were prepared by branching from a master intermediate. Subsequently, a variant of this polyphenol intermediate was used to guide the route toward dalesconol A and B. These polyketides are potent immunosuppressants. A common synthetic strategy unifies these total syntheses, much as the cyclobutenone program is comprised of three related projects.
Unifying Classical Spin Models Using A Quantum Formalism
Creators: name: De Las Cuevas, Gemma
Publisher: name: The University of British Columbia
Year: 2016

description: We have recently shown that the partition function of any classical spin model, including all discrete standard statistical models and all Abelian discrete lattice gauge theories, can be expressed as the specific instance of the partition function of a four dimensional Ising lattice gauge theory. This unifies models with apparently very different features (global vs. local symmetries, many body interactions, different dimensions, etc) in a single complete model. The proof of the result uses techniques from quantum information. In this talk we review these mappings and discuss recent developments, including quantum algorithms to approximate the partition function.

description: We study the statistics of quasiparticle and quasihole levels in small interacting disordered systems within the Hartree-Fock approximation. The distribution of the inverse compressibility, given according to Koopmans' theorem by the distance between the two levels across the Fermi energy, evolves from a Wigner distribution in the non-interacting limit to a shifted Gaussian for strong interactions. On the other hand the nature of the distribution of spacings between neighboring levels on the same side of the Fermi energy (corresponding to energy differences between excited states of the system with one missing or one extra electron) is not affected by the interaction and follows Wigner-Dyson statistics. These results are derived analytically by isolating and solving the appropriate Hartree-Fock equations for the two levels. They are substantiated by numerical simulations of the full set of Hartree-Fock equations for a disordered quantum dot with Coulomb interactions. We find enhanced fluctuations of the inverse compressibility compared to the prediction of Random Matrix Theory, possibly due to localization of the wavefunctions around the edge of the dot. The distribution of the inverse compressibility calculated from the discrete second derivative with respect to the number of particles of the Hartree-Fock ground state energy deviates from the distribution of the level spacing across the Fermi energy. The two distributions have similar shapes but are shifted with respect to each other. The deviation increases with the strength of the interaction thus indicating the breakdown of Koopmans' theorem in the strongly interacting limit.

Among all of prepared samples, Au/Ce-HEO-500 with a moderate content of Au (0.5 wt%) exhibited the lowest temperature for complete combustion of toluene (260 oC)，which decreased nearly 70 oC compared with Ce-HEO-500 support. Moreover, it also showed excellent stability for 60 h with 98% toluene conversion rate. Most importantly, under the condition of 5 vol.% H2O vapor, the toluene conversion rate remained unchanged and even increased slightly compared with that in dry air, exhibiting excellent water resistance. Combined with the characterizations of XRD, SEM, TEM, BET, Raman, H2-TPR and XPS, it was found that the high dispersion of active Au NPs, the special high-entropy structure and the synergistic effect between Au and Ce, Co, Cu are the key factors when improving the catalytic performance in the Au/Ce-HEO-500 catalyst.

description: Superatomic crystals (SACs) with tunable physical properties offer a new approach to the design of inorganic nanomaterials. Very little is known about how these systems function, or how their properties can be transformed. Here I describe work that helps to develop an understanding of how functional properties behave in SACs, and how they can be altered through superatomic intercalation or with phase transitions. Chapter 1 describes work characterizing the thermal transport behavior of SACs. We find that heat transfer is dominated by coherent inter-cluster phonons with vibrational frequencies determined by the periodicity of the SAC superstructure. We also demonstrate a transformation from amorphous to crystalline thermal transport behavior through manipulation of the vibrational landscape and orientational order of the superatoms. Chapters 2 and 3 describe the intercalation of a porous superatomic host, [Co₆Te₈(PⁿPr₃)₆][C₆₀]₃. We find that guests can be inserted into the superstructure through single-crystal-to-single-crystal transformations, dramatically transforming the electronic properties of the SAC. Using electronic absorption spectroscopy, electrical transport measurements and electronic structure calculations, we demonstrate that the intercalation is driven by the exchange of charge between the host, establishing an exciting design space for the preparation of superatomic materials. Chapter 4 describes a hierarchical solid, [Co₆Te₈(PEt₃)₆][C₇₀]₂, in which the delicate balance of interactions between constituent building blocks produces two separate phase transitions: one affecting thermal transport properties, the other transforming the electronic and magnetic behavior of the SAC. We use a wide range of structural and spectroscopic characterization tools to understand the mechanism of each transformation. This work establishes a new ability to program functional phase transitions into cluster-assembled materials. In a completely different area of study, chapter 5 describes a new covalent organic framework (COF) whose unique structure enables a post-synthetic topochemical polymerization of the framework’s linker fragments. The polymerization of the 1-3 butadiyne into a polydiacetylene backbone covalently crosslinks the material without compromising its original crystallinity. This work not only enables the preparation of more structurally resilient COFs, but also diversifies the design space for this emerging class of materials.
Inverse period mappings of $K3$ surfaces and a construction of modular forms for a lattice with the Kneser conditions

description: We explicitly construct modular forms on a $4$-dimensional bounded symmetric domain of type $IV$ based on the variation of the Hodge structures of $K3$ surfaces. We study the ring of our modular forms. Because of the Kneser conditions of the transcendental lattice of our family of $K3$ surfaces, our modular group has a good arithmetic property. Also, our results can be regarded as natural extensions of classical Siegel modular forms from the viewpoint of $K3$ surfaces.

description: N-Heterocyclic carbenes (NHCs) are an important class of compounds responsible for a wide variety of chemical transformations. NHCs may be used as organocatalysts that permit non-traditional carbon carbon bond formations due to their renowned ability to invert the electrophilic character of aldehyde carbonyl groups, a concept otherwise known as polarity reversal or umpolung reactivity. Despite their ubiquity with respect to accessing the umpolung of aldehydes, fundamental studies of these reactive species are still rather limited and narrow in scope. As a result, clarifying and solving problems relevant to umpolung-themed asymmetric catalysis becomes quite challenging. In this regard, our work has been focused on a three-pronged approach towards providing a more unified understanding of these complex catalytic systems. First, we describe the synthesis of unprecedented carboxylate-tethered triazolium NHCs and use them in the intramolecular Stetter reaction to understand their function. Second, we describe the acidities of a broad range of both chiral and achiral NHCs that have never had their acidities assessed before and use them to construct the first linear free-energy relationships of their kind. Finally, we develop a simple and noninvasive experimental protocol in which we can quickly benchmark the performance of a series of chiral catalysts by way of single competition experiments. We anticipate that these studies will have direct implications on the development of novel NHC-catalyzed reactions.

description: When modeling an application of practical relevance as an instance of a combinatorial problem X, we are often interested not merely in finding one optimal solution for that instance, but in finding a sufficiently diverse collection of good solutions. In this work we initiate a systematic study of diversity from the point of view of fixed-parameter tractability theory. First, we consider an intuitive notion of diversity of a collection of solutions which suits a large variety of combinatorial problems of practical interest. We then present an algorithmic framework which --automatically-- converts a tree-decomposition-based dynamic programming algorithm for a given combinatorial problem X into a dynamic programming algorithm for the diverse version of X. Surprisingly, our algorithm has a polynomial dependence on the diversity parameter.

description: We make a detailed analysis of Newtonian as well as relativistic core-shell models recently proposed to describe a black hole or neutron star surrounded by shells of matter, and in a seminal sense also galaxies, supernovae and star remnants since there are massive shell-like structures surrounding many of them and also evidences for many galactic nuclei hiding black holes. We discuss the unicity of the models in relation to their analyticity at the black hole horizon and also to the full elimination of conical singularities. Secondly, we study the role played by the presence/lack of discrete reflection symmetries about equatorial planes in the chaotic behavior of the orbits, which is to be contrasted with the almost universal acceptance of reflection symmetries as default assumptions in galactic modeling. We also compare the related effects if we change a true central black hole by a Newtonian central mass. The numerical findings are: 1- The breakdown of the reflection symmetry about the equatorial plane in both Newtonian and relativistic core-shell models does i) enhance in a significant way the chaoticity of orbits in reflection symmetric oblate shell models and ii) inhibit significantly also the occurrence of chaos in reflection symmetric prolate shell models. In particular, in the prolate case the lack of the reflection symmetry provides the phase space with a robust family of regular orbits that is otherwise not found at higher energies. 2- The relative extents of the chaotic regions in the relativistic cases (i. e. with a true central black hole) are significantly larger than in the corresponding Newtonian ones (which have just a $-1/r$ central potential).

description: The electromagnetic form factor is extracted from both components of the electromagnetic current: J(plus) and J(minus) with a pseudo-scalar coupling of the quarks to the kaon. In the case of J(plus) there is no pair term contribution in the Drell-Yan frame. However, J(minus) component of the electromagnetic current the pair term contribution is different from zero and is necessary include it to preserve the rotational symmetry of the current.

description: This article conducts a literature review of current and future challenges in the use of artificial intelligence (AI) in cyber physical systems. The literature review is focused on identifying a conceptual framework for increasing resilience with AI through automation supporting both, a technical and human level. The methodology applied resembled a literature review and taxonomic analysis of complex internet of things (IoT) interconnected and coupled cyber physical systems. There is an increased attention on propositions on models, infrastructures and frameworks of IoT in both academic and technical papers. These reports and publications frequently represent a juxtaposition of other related systems and technologies (e.g. Industrial Internet of Things, Cyber Physical Systems, Industry 4.0 etc.). We review academic and industry papers published between 2010 and 2020. The results determine a new hierarchical cascading conceptual framework for analysing the evolution of AI decision-making in cyber physical systems. We argue that such evolution is inevitable and autonomous because of the increased integration of connected devices (IoT) in cyber physical systems. To support this argument, taxonomic methodology is adapted and applied for transparency and justifications of concepts selection decisions through building summary maps that are applied for designing the hierarchical cascading conceptual framework.
