description: The genesis of this thesis began in 2006 with the renovation of what is now known as The Grand Gallery located within the American Museum of Natural History (AMNH) campus and was predicated on the discovery of the floor plan for the structural analysis of the floor load for what was known at the time as the Foyer to the museum on West 79th Street circa 1902. On this drawing were taped the names of Charles Volz and James Brown Lord, no date nor title block are listed on the drawing. This was the second encounter after having previously worked on the renovation of James Brown Lord’s Yorkville Branch Library at 222 East Seventy-ninth Street in 1986 in conjunction with Gwathmey Siegel and Associates; ‘the first of the Carnegie Branch Libraries’ built in New York City in 1902 for the New York Public Library (NYPL), Astor, Lenox and Tilden Foundations. Both sites were constructed posthumously to Lord, but were supervised and completed by Charles Volz, his ‘associate'.

description: A single calorimeter station for the Muon $g-2$ experiment at Fermilab includes the following subsystems: a 54-element array of PbF$_{2}$ Cherenkov crystals read out by large-area SiPMs, bias and slow-control electronics, a suite of 800 MSPS waveform digitizers, a clock and control distribution network, a gain calibration and monitoring system, and a GPU-based frontend read out through a MIDAS data acquisition environment. The entire system performance was evaluated using 2.5 - 5 GeV electrons at the End Station Test Beam at SLAC. This paper includes a description of the individual subsystems and the results of measurements of the energy response and resolution, energy-scale stability, timing resolution, and spatial uniformity. All measured performances meet or exceed the $g-2$ experimental requirements. Based on the success of the tests, the complete production of the required 24 calorimeter stations has been made and installation into the main experiment is complete. Furthermore, the calorimeter response measurements determined here informed the design of the reconstruction algorithms that are now employed in the running $g-2$ experiment.

description: We analyse the topological (knot-theoretic) features of a certain codimension-one bifurcation of a partially hyperbolic fixed point in a flow on $\real^3$ originally described by Shil'nikov. By modifying how the invariant manifolds wrap around themselves, or ``pleat,'' we may apply the theory of templates, or branched two-manifolds, to capture the topology of the flow. This analysis yields a class of flows which bifurcate from a Morse-Smale flow to a Smale flow containing periodic orbits of all knot and link types.

description: Documenting the extent of cellular diversity is a critical step in defining the functional organization of the nervous system. In this context, we sought to develop statistical methods capable of revealing underlying cellular diversity given incomplete data sampling - a common problem in biological systems, where complete descriptions of cellular characteristics are rarely available. We devised a sparse Bayesian framework that infers cell type diversity from partial or incomplete transcription factor expression data. This framework appropriately handles estimation uncertainty, can incorporate multiple cellular characteristics, and can be used to optimize experimental design. We applied this framework to characterize a cardinal inhibitory population in the spinal cord.
      Animals generate movement by engaging spinal circuits that direct precise sequences of muscle contraction, but the identity and organizational logic of local interneurons that lie at the core of these circuits remain unresolved. By using our Sparse Bayesian approach, we showed that V1 interneurons, a major inhibitory population that controls motor output, fractionate into diverse subsets on the basis of the expression of nineteen transcription factors. Transcriptionally defined subsets exhibit highly structured spatial distributions with mediolateral and dorsoventral positional biases. These distinctions in settling position are largely predictive of patterns of input from sensory and motor neurons, arguing that settling position is a determinant of inhibitory microcircuit organization. Finally, we extensively validated inferred cell types by direct experimental measurement and then, extend our Bayesian framework to full transcriptome technologies. Together, these findings provide insight into the diversity and organizational logic through which inhibitory microcircuits shape motor output.

description: We propose a generalized discrimination scheme for mixed quantum states. In the present scenario we allow for certain fixed fraction of inconclusive results and we maximize the success rate of the quantum-state discrimination. This protocol interpolates between the Ivanovic-Dieks-Peres scheme and the Helstrom one. We formulate the extremal equations for the optimal positive operator valued measure describing the discrimination device and establish a criterion for its optimality. We also devise a numerical method for efficient solving of these extremal equations.

description: Classification of jets with deep learning has gained significant attention in recent times. However, the performance of deep neural networks is often achieved at the cost of interpretability. Here we propose an interpretable network trained on the jet spectrum $S_{2}(R)$ which is a two-point correlation function of the jet constituents. The spectrum can be derived from a functional Taylor series of an arbitrary jet classifier function of energy flows. An interpretable network can be obtained by truncating the series. The intermediate feature of the network is an infrared and collinear safe C-correlator which allows us to estimate the importance of a $S_{2}(R)$ deposit at an angular scale R in the classification. The performance of the architecture is comparable to that of a convolutional neural network (CNN) trained on jet images, although the number of inputs and complexity of architecture is significantly simpler than the CNN classifier. We consider two examples: one is the classification of two-prong jets which differ in color charge of the mother particle, and the other is a comparison between Pythia 8 and Herwig 7 generated jets.

description: Nebular emission lines associated with galactic HII regions carry information about both physical properties of the ionised gas and the source of ionising photons as well as providing the opportunity of measuring accurate redshifts and thus distances once a cosmological model is assumed. While nebular line emission has been extensively studied at lower redshift there are currently only few constraints within the epoch of reionisation (EoR, $z>6$), chiefly due to the lack of sensitive near-IR spectrographs. However, this will soon change with the arrival of the Webb Telescope providing sensitive near-IR spectroscopy covering the rest-frame UV and optical emission of galaxies in the EoR. In anticipation of Webb we combine the large cosmological hydrodynamical simulation Bluetides with photoionisation modelling to predict the nebular emission line properties of galaxies at $z=8\to 13$. We find good agreement with the, albeit limited, existing direct and indirect observational constraints on equivalent widths though poorer agreement with luminosity function constraints.

description: Comparative policy analysis revealed the phenomenon that certain national environmental policy initiatives have been adopted by a variety of countries. This empirical finding inspired the research interest: What are the reasons for this observable spreading? Is it coincidence, is it lesson-drawing, competition, emulation or is it the result of decreasing nation state’s discretion due to mandatory compliance requirements of international law? The concept of policy diffusion has been found quite suitable to analyse the spreading of different environmental policy innovations. The analysis of diffusion processes is a challenging endeavour as it has to consider a complex interplay of three factors: International and transnational factors which horizontally and vertically interlink jurisdictions and enable the transfer of policy content; national factors which filter experiences from abroad and determine national responsiveness to external stimuli; and the characteristics of the policy innovation which may indicate its “diffusablity”. This research note is a synthesis of findings of the project on “The Diffusion of Environmental Innovations as an Aspect of Globalisation” financed by the Volkswagen Foundation. It confronts central assumptions of diffusion research with the findings of various project researchers. The empirical core of the project consists of a set of data concerning the adoption of 21 environmental policy innovations in 48 countries over a time period of 50 years. In a first step the paper analyses whether across all of the 21 environmental innovations typical pattern of spread can be identified in order to detect those channels of diffusion which seemingly further diffusion processes. Following up this discussion the paper debates international factors which are assumed to have an crucial impact on the pattern of diffusion. Within this section interrelations with other types of global or regional governance are discussed. This comprises both special features of the EU context as well as the impact of global norms. After giving a short overview concerning the micro-foundations of the diffusion effects of international stimuli the paper proceeds to discuss the restrictions in the diffusion process, which heavily depend on innovation characteristics and national capacities to innovate. The paper concludes with raising new research questions in order to inspire the scientific debate on globalisation and policy convergence.
Deconstructing Pakistan’s education policy within the Gender and Development Framework: The cases of Punjab and Khyber Pakhtunkhwa

description: This thesis makes a case for education policies in Pakistan that take into account the diverse needs of its populace with regard to girls’ education across different locales and contexts within provinces. Using the Gender and Development (GAD) framework, it assesses whether education policies in Pakistan address the barriers to girls’ education, as expressed by communities in a customized and gender-sensitive manner. It found that provincial governments are addressing community expressed barriers to girls’ education in an incomplete and inconsistent manner. While they have displayed an understanding of these issues, there remains much scope for improvement and a deeper and long-term commitment to girls’ education is required to achieve gender parity at the primary level of schooling.

description: With the growing number of gravitational-wave detections and the advent of large galaxy redshift surveys, a new era in cosmology is unfolding. This study explores the synergies between gravitational waves and galaxy surveys to jointly constrain cosmological and gravitational-wave population parameters. We introduce CHIMERA, a novel code for gravitational-wave cosmology combining information from the population properties of compact binary mergers and galaxy catalogs. We study constraints for scenarios representative of LIGO-Virgo-KAGRA O4 and O5 observing runs, assuming to have a complete catalog of potential host galaxies with either spectroscopic or photometric redshift measurements. We find that a percent-level measurement of $H_0$ could be achieved with the best 100 binary black holes in O5 using a spectroscopic galaxy catalog. In this case, the intrinsic correlation that exists between $H_0$ and the binary black hole population mass scales is broken. Instead, by using a photometric catalog the accuracy is degraded up to a factor of $\sim\! 9$, leaving a significant correlation between $H_0$ and the mass scales that must be carefully modeled to avoid bias. Interestingly, we find that using spectroscopic redshift measurements in the O4 configuration yields a better constraint on $H_0$ compared to the O5 configuration with photometric measurements. In view of the wealth of gravitational-wave data that will be available in the future, we argue the importance of obtaining spectroscopic galaxy catalogs to maximize the scientific return of gravitational-wave cosmology.

description: The struggles for land discussed in this paper have occurred in contexts characterized by some improvement of laws and policies designed to protect ethnic and cultural minorities in Brazil and Colombia, following the “multicultural turn” in international law. The paper discusses to a greater extent the cases of communities of Afro-descendants who live in areas disputed by agribusiness companies interested in expanding palm plantations mostly for biodiesel production. We found out that the introduction of new rights has first unleashed a local process of ethnic re-identification. In a certain way, minority rights themselves have created those minorities they are supposed to protect. Nevertheless, new minority rights have also reframed the conditions under which struggles for land are conducted and negotiated in Colombia as well as in Brazil. Seen as relays in an electrical circuit, minority rights serve to modulate power at the local level: in some cases, new rights amplify minorities’ power; in other situations, they can help contain the problems of abuses of power.

description: Pregnancy is a physiologically demanding process, vulnerable to several modifiable lifestyle factors including diet. Malnutrition, or a dietary imbalance, can have severe implications on maternal physiology, as well as placental and fetal development. Several aberrant pregnancy outcomes have been linked with an abnormal diet disturbing maternal metabolism, hormone status and placental function. Dietary changes also disrupt the intrauterine environment for the developing fetus, altering growth and predisposing offspring to development of diseases later in life. Abnormal pregnancy outcomes are dependent on the specific timing and type of dietary insult. A major micronutrient deficiency present in multiple human populations is selenium. Deficiencies in micronutrients, such as selenium, have been linked to numerous pregnancy complications; however, the specific ramifications of a selenium deficient diet on pregnancy outcomes and fetal development is relatively unknown. Selenium is incorporated into selenoproteins involved in numerous biological and cellular processes including antioxidant function, thyroid hormone metabolism, endoplasmic reticulum stress and skeletal muscle development. Given selenium is associated with undesirable pregnancy outcomes, the primary aim of this thesis was to investigate the effects of selenium deficiency on pregnancy physiology, placental function, fetal development and offspring outcomes.

description: We report the first detection of an optical millisecond pulsar with the fast photon counter Aqueye+ in Asiago. This is an independent confirmation of the detection of millisecond pulsations from PSR J1023+0038 obtained with SiFAP at the Telescopio Nazionale Galileo. We observed the transitional millisecond pulsar PSR J1023+0038 with Aqueye+ mounted at the Copernicus telescope in January 2018. Highly significant pulsations were detected. The rotational period is in agreement with the value extrapolated from the X-ray ephemeris, while the time of passage at the ascending node is shifted by $11.55 \pm 0.08$ s from the value predicted using the orbital period from the X-rays. An independent optical timing solution is derived over a baseline of a few days, that has an accuracy of $\sim 0.007$ in pulse phase ($\sim 12$ $μ$s in time). This level of precision is needed to derive an accurate coherent timing solution for the pulsar and to search for possible phase shifts between the optical and X-ray pulses using future simultaneous X-ray and optical observations.

To fully utilized the information of structured sparse signals efficiently, we also propose a sensing method while the sampling acquisition is expansive, and study its sample limit and algorithms for signal recovery with limited samples.

description: We present an efficient non-enzymatic hydrogen peroxide sensor composed of flower-like silver microstructures. The silver microstructures´ morphology is controlled by adding minute amounts of either succinic or malonic acid as directing agents. Morphologically, silver particles showed ball-like structures in the absence of both directing agents, while the presence of 50 ppm of succinic acid and malonic acid lead to monodisperse chrysanthemum and water-lily flower-like structure, respectively. A higher concentration of succinic acid resulted in a rose flower-like structures. Electrochemically, the rose flower-like silver microstructures exhibited the best performance for H2O2 detection as evaluated by their outstanding electrocatalytic activity (12 times higher) and sensitivity (2.4 mM−1 cm−2, 24 times higher) with lower detection limit (0.4 µM, 5 times smaller) together with their excellent H2O2 selectivity compared to that of the ball-shaped structures. Additionally, rose-flower microstructures exhibited excellent long-term stability; 11 and 3 times higher compared to ball- and water-lily structures, respectively. This substantial performance enhancement is attributed to their unique flower-like structure providing a higher number of active surface sites (at least 8 times higher) and a faster detachment rate of in-situ generated oxygen bubbles from their surface.

description: We study a screening mechanism in the context of scalar-vector-tensor (SVT) theories. This screening mechanism is based on both the derivative self-interactions of the vector field and the interactions of the scalar field with the vector field and curvature. We calculate the field equations in a spherically symmetric space-time, and then, we study the conditions for which this mechanism is successful in a weak gravitational background. In order to corroborate these analytical results, we have performed a numerical integration of the full equations. Finally, the corrections to the gravitational potentials have also been computed. We conclude that the present model, including both kinds of interactions, can avoid the propagation of the additional longitudinal mode arising in these theories. We also show that the space parameter of the model is compatible with solar system constraints. This result extends the previous one found in the literature for generalized Proca theories to the case of SVT theories in the presence of scalar-vector interactions.

title: Designing a visual grammar to enable more effective stakeholder participation in scoping organizational change: a physics of notations approach
Creators: name: Harris, Louise A.
Publisher: name: Memorial University of Newfoundland
Year: 2021

description: Successful organization change depends on effectively engaging impacted stakeholders early in the change process so that change leaders and stakeholders have a common understanding of the scope, benefits, and risks of the change. However, communicating a succinct and holistic view of the change and gaining shared understanding on what needs to change can be challenging. The use of sequential written communication and ad hoc graphics imposes a high cognitive load on stakeholders. This results in reluctance or inability for stakeholders to engage when their availability and mental resources are constrained due to operational demands. This research explores the design of a conceptual modeling grammar that generates single page, intuitive diagrams to reduce the cognitive load for stakeholders in understanding and defining the scope of organizational change. We first developed a domain ontology and a grammar based on theory. We then used the action design research approach to test and refine the grammar through three interventions in service delivery change in healthcare organizations. In each intervention we were able to overcome existing stakeholder engagement challenges and enhance stakeholder understanding of the scope of change being undertaken.

Metals--Conservation and restoration

description: This thesis provides in-depth research into the rise and fall of Monel metal - the background, stakeholder intent, competition and current conservation practice while carrying out the first known atmospheric corrosion analysis in over fifty years. Covering the reasons behind the vacuum of information on this trademarked and now specialty metal, the thesis is broken into a historical and technical component. The initial section consists of the beginnings of The International Nickel Company and the demand for nickel materiel at the beginning of the twentieth-century, the discovery of the alloy’s anti-corrosive nature and high mechanical strength, the evolving manufacturing processes, its branding after the war and the aesthetic intent from both the company and fabricator perspective, and the slow discovery of the “fogging” of nickel. The technical component, carried out in the Columbia University Historic Preservation laboratory towards the end of 2019, breaks down the materials science, including composition, various types and finishes of the alloy, and subsequent testing of corroded surfaces with X-ray fluorescence (XRF), X-ray diffraction (XRD), Raman spectroscopy and gas chromatography-mass spectrometry (GC-MS). Case studies are carried out at Woodlawn Cemetery as well as at Bryn Athyn Historic District. A literature review is provided throughout the text with findings and recommendations to offer further preservation discussion for future generations of architects and conservators.

description: In 3 dimensions, the Ising model is in the same universality class as $ϕ^4$-theory, whose massive 3-loop tetrahedral diagram, $C^{Tet}$, was of an unknown analytical nature. In contrast, all single-scale 4-dimensional tetrahedra were reduced, in hep-th/9803091, to special values of exponentially convergent polylogarithms. Combining dispersion relations with the integer-relation finder PSLQ, we find that $C^{Tet}/2^{5/2} = Cl_2(4α) - Cl_2(2α)$, with $Cl_2(θ):=\sum_{n>0}\sin(nθ)/n^2$ and $α:=\arcsin\frac13$. This empirical relation has been checked at 1,000-digit precision and readily yields 50,000 digits of $C^{Tet}$, after transformation to an exponentially convergent sum, akin to those studied in math.CA/9803067. It appears that this 3-dimensional result entails a polylogarithmic ladder beginning with the classical formula for $π/\sqrt2$, in the manner that 4-dimensional results build on that for $π/\sqrt3$.

A hybrid model employs both information theory and AdS/QCD, where configurational-entropic Regge trajectories, relating the configurational entropy of the tensor mesons family to their $S$ spin, and also to their experimental mass spectra, are derived and analyzed. Therefore, the mass spectra of higher spin-$S$ tensor meson resonances is obtained and compared to the existing data in PDG.

description: Let $x_1,x_2,...,x_n$ be the zeroes of a polynomial P(x) of degree n and $y_1,y_2,...,y_m$ be the zeroes of another polynomial Q(y) of degree m. Our object of study is the permanent $\per(1/(x_i-y_j))_{1\le i\le n, 1\le j\le m}$, here named "Scott-type" permanent, the case of $P(x)=x^n-1$ and $Q(y)=y^n+1$ having been considered by R. F. Scott. We present an efficient approach to determining explicit evaluations of Scott-type permanents, based on generalizations of classical theorems by Cauchy and Borchardt, and of a recent theorem by Lascoux. This continues and extends the work initiated by the first author ("Généralisation de l'identité de Scott sur les permanents," to appear in Linear Algebra Appl.). Our approach enables us to provide numerous closed form evaluations of Scott-type permanents for special choices of the polynomials P(x) and Q(y), including generalizations of all the results from the above mentioned paper and of Scott's permanent itself. For example, we prove that if $P(x)=x^n-1$ and $Q(y)=y^{2n}+y^n+1$ then the corresponding Scott-type permanent is equal to $(-1)^{n+1}n!$.

description: The space density of late M dwarfs, subtypes M7-M9.5, is not well determined. We applied the photo-type method to $iz$ photometry from the Sloan Digital Sky Survey and $YJHK$ photometry from the UKIRT Infrared Deep Sky Survey, over an effective area of 3070 $deg^{2}$, to produce a new, bright $J$(Vega) < 17.5, homogeneous sample of 33 665 M7-M9.5 dwarfs. The typical S/N of each source summed over the six bands is > 100. Classifications are provided to the nearest half spectral subtype. Through a comparison with the classifications in the BOSS Ultracool Dwarfs (BUD) spectroscopic sample, the typing is shown to be accurately calibrated to the BUD classifications and the precision is better than 0.5 subtypes rms; i.e. the photo-type classifcations are as precise as good spectroscopic classifications. Sources with large $χ^2$ > 20 include several catalogued late-type subdwarfs. The new sample of late M dwarfs is highly complete, but there is a bias in the classification of rare peculiar blue or red objects. For example, L subdwarfs are misclassified towards earlier types by approximately two spectral subtypes. We estimate that this bias only affects ~1% of the course. Therefore the sample is well suited to measure the luminsoity function and investigate the softening towards the Galactic plane of the exponential variation of density with height.

Study of scalar particles through the Klein-Gordon equation under rainbow gravity effects in Bonnor-Melvin-Lambda space-time

description: In our investigation, we explore the quantum dynamics of charge-free scalar particles through the Klein-Gordon equation within the framework of rainbow gravity's, considering the Bonnor-Melvin-Lambda (BML) space-time background. The BML solution is characterized by the magnetic field strength along the axis of symmetry direction which is related with the cosmological constant $Λ$ and the topological parameter $α$ of the geometry. The behavior of charge-free scalar particles described by the Klein-Gordon equation is investigated, utilizing two sets of rainbow functions: (i) $f(χ)=\frac{(e^{β\,χ}-1)}{β\,χ}$,\, $h(χ)=1$ and (ii) $f(χ)=1$,\, $h(χ)=1+\frac{β\,χ}{2}$. Here $0 < \Big(χ=\frac{|E|}{E_p}\Big) \leq 1$ with $E$ represents the particle's energy, $E_p$ is the Planck's energy, and $β$ is the rainbow parameter. We obtain the approximate analytical solutions for the scalar particles and conduct a thorough analysis of the obtained results. Afterwards, we study the quantum dynamics of quantum oscillator fields within this BML space-time, employing the Klein-Gordon oscillator. Here also, we choose the same sets of rainbow functions and obtained approximate eigenvalue solution for the oscillator fields. Notably, we demonstrate that the relativistic approximate energy profiles of charge-free scalar particles and oscillator fields get influenced by the topology of the geometry and the cosmological constant. Furthermore, we show that the energy profiles of scalar particles get modifications by the rainbow parameter and the quantum oscillator fields by both the rainbow parameter and the frequency of oscillation

title: Information Criterion and Joint Determination of the Numbers of Regimes and Variables in Markov Switching Model: Simulation and Empirical Application
Creators: name: Awirothananon, Thatphong
Publisher: name: Griffith University
Year: 2009
Subjects: subject: Information criteria
subject: Markov switching model

description: This study has three purposes. The first one is to examine the performance of four information criteria in the context of joint determination of the numbers of regimes and variables in Markov switching model (hereafter called the MS model). These criteria are Akaike (1974) information criterion (hereafter called AIC), Schwarz (1978) information criterion (hereafter called SIC), HQC (Hannan & Quinn 1979), and Markov switching criterion: MSC (Smith, Naik & Tsai 2006). The second purpose is to investigate further whether the numbers of regimes and variables in aggregate time series are similar to those in individual time series. Third, to verify the simulation results from the second objective, this study applies the MS model to both aggregate and individual time series in reality.

An Alternative Mechanism for the Delivery of Scholarly Journal Articles

Subjects: Patron driven acquisition, Charleston, Readcube

description: Traditional collection management of serials through site licenses and subscriptions is increasingly unsustainable due to rising costs and steady or falling library budgets. The ensuing gaps in access have led to widespread illicit file sharing, resulting in the disintermediation of libraries and the devaluing of publishers. It has therefore become essential to explore alternatives for the delivery of journal literature. We report on the exploration of a new mechanism for the provision of scholarly articles using patron driven acquisition. During the 2012-2013 academic year, the University of Utah Marriott Library, ReadCube, and Nature Publishing Group collaborated on the development and testing of ReadCube Access, an article delivery service designed to allow researchers to immediately access individual articles at a cost lower than traditional interlibrary loan, pay per view or document delivery.

 The goal of this session is to explore the economics of collection management from the perspective of supplying needed scholarly articles, and discuss how new technologies like ReadCube Access and patron driven acquisition can support that aim. The session will involve a frank discussion of the effects of and attitudes toward illicit file sharing, from which the audience will learn about the scale of file sharing and how it affects the perceived value and therefore funding of libraries. An interactive workshop on cost per use assessment for various acquisition mechanisms will elucidate how the economics of acquisition mechanisms change with demand and under which conditions patron driven acquisition will save libraries money while increasing patron engagement and satisfaction.
