Geometric and morphological behavior of self-limiting electrospray deposition
Creators: name: Lei, Lin
Publisher: name: No Publisher Supplied
Year: 2021

description: Electrospray deposition (ESD) utilizes the balance of electrostatic forces and surface tension within a charged spray to produce charged micro droplets with narrow dispersion in size. In ESD, each droplet carries a small quantity of suspended material to a target substrate. Past ESD falls into major categories: (1) continuous spray of films onto conducting substrates and (2) spray of isolated droplets onto insulating substrates. A cross over regime, or a self-limited spray, has only been limitedly observed in the spray of insulating materials onto conductive substrates. In such sprays, a limiting thickness emerges where the accumulation of charge repels further spray. In this dissertation, we present a systematic investigation on the self-limiting electrospray deposition (SLED), including (1) fundamental mechanism of thickness-limited spray, (2) geometry limits of SLED, (3) compositional limits of SLED and (4) morphological control through homogenous gelation in SLED. (1) We have demonstrated that SLED will occur when spraying insulating glassy materials from volatile solvents, with the substrate temperature below its glass transition temperature. This leads to charge accumulation on the coatings surface that slows the growth of the film thickness. (2) We employed model macroscale substrates to quantitatively study the technique’s limits with regard to geometry and scale. Further, to optimize the fabrication process for micro-coatings by SLED, we combined SLED with pre-existing polymer films, optionally patterned, to study SLED’s fundamental behavior in a bilayer geometry. The results reveal that the pre-deposited coatings can affect the coating thickness by SLED and the selection of polymer coatings determines the magnitude of this effect. (3) We have investigated the compositional limits of self-limiting and non-self-limiting solute blends through SLED. The results show that composited polymers still exhibit self-limiting ability through SLED and their mechanical properties could be tuned effectively within compositional ranges. (4) The morphology of coatings created by ESD can be generally divided into three categories: wire mats, particles, and films. We have demonstrated that the ESD of a fibril gel former, methylcellulose (MC) in water:ethanol, leads to gelation enhanced by shear and surface charge that electrospins on a drop-by-drop basis to create forests of individual nanowires.
A numerical study of steady state cooling in a raised floor data center with a ceiling plenum return
Creators: name: Levinson, Jamie D.
Publisher: name: No Publisher Supplied
Year: 2021

description: In this study, the ability of a cooling system to remove heat from a data center is investigated. The governing equations with given boundary conditions are solved numerically using ANSYS Fluent 2020R1 which was validated via comparison with the benchmark problem of natural convection in a square cavity. The number of fans present in each server, the hot aisle width, the ceiling height, and the use of hot aisle containment was varied in order to determine their influence on how well the data center was cooled. The server racks are modeled as porous media and the temperatures at key location are used to determine various thermal metrics which allows for an investigation of the changes at both the room and rack level.
Blurred boundaries: negotiating normativity in late Soviet and early post-Soviet narratives about alcohol
Creators: name: Levkovitch, Lidia A.
Publisher: name: No Publisher Supplied
Year: 2021

description: This dissertation studies literary and non-literary discourses related to normative and deviant alcohol use during the late Soviet period, a transformative time in the history of Russia. It connects these discourses to the process of disintegration of Soviet ideology as conceptualized by Alexei Yurchak, aiming to demonstrate that depictions of the Soviet subject’s engagements with alcohol provided a unique way to reflect a reconfiguration of normativity within a shifting social and intellectual context. In doing so, the project takes into account the fact that all the texts it examines, from medical literature and newspaper articles to literary fiction, functioned in an environment strongly influenced by censorship and a hegemonic official discourse, a situation that often led to alcohol serving as a coded link to other topics. Specifically, the dissertation traces changes in stereotypes associated with drinking excesses during the late Soviet period, concluding that propaganda discourses consistently connected drunkenness with characteristics and behaviors “undesirable” in a Soviet subject, even as the authoritative idea of normativity changed through the years. Close readings of published fiction by Soviet writers support the idea that conversations about drinking can be a language of power to the same degree as drinking rituals themselves. Recognizing the role of Socialist Realism as the dominant literary mode, the dissertation delves into the ways late Soviet and early post-Soviet works of fiction portrayed alcohol use in order to engage with the tropes of Socialist Realism, constructing a more up-to-date subjectivity. With the help of trauma theory, the dissertation demonstrates how depictions of intoxication, alcohol-induced blackouts, and addiction-driven repetition inflict postmodernist fragmentation on the subject in the work of Andrei Bitov. It concludes by examining early post-Soviet fiction’s attempts to reconstitute a subject adapted to the new economic and social reality. The dissertation posits that this is accomplished with the help of a turn toward the archaic trope of the hero journey, in which alcohol is used as a bridge between realist narrative and myth.
A modeling language for multi-tenant data architecture evolution in cloud applications
Creators: name: Jumagaliyev, Assylbek
Publisher: name: Lancaster University
Year: 2019

description: Multi-tenancy enables efficient resource utilization by sharing application resources across multiple customers (i.e., tenants). Hence, applications built using this pat- tern can be offered at a lower price and reduce maintenance effort as less application instances and supporting cloud resources must be maintained. These properties en- courage cloud application providers to adopt multi-tenancy to their existing applications, yet introducing this pattern requires significant changes in the application structure to address multi-tenancy requirements such as isolation of tenants, extensibility of the application, and scalability of the solution. In cloud applications, the data layer is often the prime candidate for multi-tenancy, and it usually comprises a combination of different cloud storage solutions such as blob storage, relational and non-relational databases. These storage types are conceptually and tangibly divergent, each requiring its own partitioning schemes to meet multi-tenancy requirements. Currently, multi-tenant data architectures are implemented using manual coding methods, at times following guidance and patterns offered by cloud providers. However, such manual implementation approach tends to be time consuming and error prone. Several modeling methods based on Model-Driven Engineer- ing (MDE) and Software Product Line Engineering (SPLE) have been proposed to capture multi-tenancy in cloud applications. These methods mainly generate cloud deployment configurations from an application model, though they do not automate implementation or evolution of applications. This thesis aims to facilitate development of multi-tenant cloud data architectures using model-driven engineering techniques. This is achieved by designing and implementing a novel modeling language, CadaML, that provides concepts and notations to model multi-tenant cloud data architectures in an abstract way. CadaML also provides a set of tools to validate the data architecture and automatically produce corresponding data access layer code. The thesis demonstrates the feasibility of the modeling language in a practical setting and adequacy of multi-tenancy implementation by the generated code on an industrial business process analyzing application. Moreover, the modeling language is empirically compared against manual implementation methods to inspect its effect on developer productivity, development effort, reliability of the application code, and usability of the language. These outcomes provide a strong argument that the CadaML modeling language effectively mitigates the high overhead of manual implementation of multi-tenant cloud data layers, significantly reducing the required development complexity and time.
Gaussian Process Regression based heat and electrical models for a lithium-ion battery cell

Publisher: name: No Publisher Supplied
Year: 2021

description: The imbalance of electrical potential, temperature, and the State of Charge (SOC) within battery cells may cause safety issues in applications. Models that can predict battery cells’ thermal and electrical behaviors become necessary for real-time battery management systems to regulate the imbalance.This dissertation introduces a Gaussian Process Regression (GPR) based data-driven framework that succeeds the Multi-Scale Multi-Dimensional (MSMD) modeling structure developed by (Kim, et al. 2011). The framework predictions can reach high accuracies as the full-order full-distribution simulations based on MSMD. It relies on the pseudo-2D model developed by (Doyle, Fuller and Newman 1993) to generate training data, which shifts computation burdens from real-time battery management systems to lab data preparation.This dissertation introduces deterministic and uncertain input GPR models in the battery cell’s particle and electrode domains. These models work in different phases of the battery cell potentiostatic discharge simulation, where different types of probabilistic finite element analysis (FEA) procedures are applied correspondingly. Dimensional model representation approximations combined with Gauss-Hermite quadrature methods are employed to give solution distributions of temperatures and plate electrical potential differences in the cell domain. Testing results illustrate the reliability of the GPR based data-driven framework in accuracy and stability under various circumstances; this was accomplished by comparing our results from other researchers’ methods.

description: The nuclear-matter liquid-gas phase transition induces instabilities against finite-size density fluctuations. This has implications for both heavy-ion-collision and compact-star physics. In this paper, we study the clusterization properties of nuclear matter in a scenario of spinodal decomposition, comparing three different approaches: the quantal RPA, its semi-classical limit (Vlasov method), and a hydrodynamical framework. The predictions related to clusterization are qualitatively in good agreement varying the approach and the nuclear interaction. Nevertheless, it is shown that i) the quantum effects reduce the instability zone, and disfavor short-wavelength fluctuations; ii) large differences appear bewteen the two semi-classical approaches, which correspond respectively to a collisionless (Vlasov) and local equilibrium description (hydrodynamics); iii) the isospin-distillation effect is stronger in the local equilibrium framework; iv) important variations between the predicted time-scales of cluster formation appear near the borders of the instability region.

description: We explore the link between the melting scenarios of two-dimensional systems of hard disks and squares through replica-exchange Monte Carlo simulations of hard superdisks. The well-known melting scenarios are observed in the disk and square limits, while we observe an unusual three-step scenario for dual-shapes. We find that two mesophases mediate the melting: a hexatic phase and another fluid phase with a $D_2$ local symmetry, we call it rhombatic, where both bond and particle orientational orders are quasi-long-range. Our results show that not only can the melting process of liquid-crystal forming molecules be complicated, where elongated shapes stabilize several mesophases, but also that of anisotropic quasispherical molecules.

description: Autonomous oscillations in biological systems may have a biochemical origin or result from an interplay between force-generating and visco-elastic elements. In molecular motor assemblies the force-generating elements are molecular engines and the visco-elastic elements are stiff cytoskeletal polymers. The physical mechanism leading to oscillations depends on the particular architecture of the assembly. Existing models can be grouped into two distinct categories: systems with a delayed force activation and anomalous force-velocity relations. We discuss these systems within phase plane analysis known from the theory of dynamic systems and by adopting methods from control theory, the Nyquist stability criterion.

description: Widespread conspiracy theories, like those motivating anti-vaccination attitudes or climate change denial, propel collective action and bear society-wide consequences. Yet, empirical research has largely studied conspiracy theory adoption as an individual pursuit, rather than as a socially mediated process. What makes users join communities endorsing and spreading conspiracy theories? We leverage longitudinal data from 56 conspiracy communities on Reddit to compare individual and social factors determining which users join the communities. Using a quasi-experimental approach, we first identify 30K future conspiracists-(FC) and 30K matched non-conspiracists-(NC). We then provide empirical evidence of importance of social factors across six dimensions relative to the individual factors by analyzing 6 million Reddit comments and posts. Specifically in social factors, we find that dyadic interactions with members of the conspiracy communities and marginalization outside of the conspiracy communities, are the most important social precursors to conspiracy joining-even outperforming individual factor baselines. Our results offer quantitative backing to understand social processes and echo chamber effects in conspiratorial engagement, with important implications for democratic institutions and online communities.

Here I consider extended models for which this expansion is perturbatively stable. The extreme case of an SU(2) gauge theory whose configuration space is restricted to center-symmetric orbits has recently been investigated on the lattice hep-lat/0509156. In extension of my talk, a discussion and possible interpretation of the observed finite temperature phase transition is given. The transfer matrix of constrained SU(N) lattice gauge theory is constructed for any finite temperature.

We interpret this function G$_{d}(q) $ as a $(d+1) $- point correlation function $\mathcal{G}_{d+1}(z_{0},...,z_{d}) $ of some local vertex operators $\mathcal{O}%_{j}(z_{j}) $. We determine these operators and show that they are particular composites of q-deformed hierarchical vertex operators $% Γ_{\pm}^{(p)}$, with a positive integer p. In agreement with literature's results, we find that G$_{d}(q) $, $d\geq 4$, cannot be the generating functional of all \textit{d- dimensional} generalized Young diagrams .

It is rather well established that they are unstable with respect to small perturbations of the NLS equation. Concerning perturbations of these solutions within the NLS dynamics, there is the following common believe in the literature. Let the NLS background be unstable with respect to the first $N$ modes; then i) if the $M$ unstable modes of the $AB_M$ solution are strictly contained in this set ($M1$.

description: Generally, a superconducting nanowire single-photon detector (SNSPD) is composed of wires with a typical width of ~100 nm. Recent studies have found that superconducting strips with a micrometer-scale width can also detect single photons. Compared with the SNSPD, the superconducting microstrip single-photon detector (SMSPD) has smaller kinetic inductance, higher working current, and lower requirement in fabrication accuracy, providing potential applications in the development of ultra-large active area detectors. However, the study on SMSPD is still in its infancy, and the realization of its high-performance and practical use remains an opening question. This study demonstrates a NbN SMSPD with a saturated system detection efficiency (SDE) of ~92.2% at a dark count rate of ~200 cps, a polarization sensitivity of ~1.03, and a minimum timing jitter of ~48 ps, at the telecom wavelength of 1550 nm when coupled with a single mode fiber and operated at 0.84 K. Furthermore, the detector's SDE is over 70% when operated at a 2.1-K closed-cycle cryocooler.

description: Spontaneous orbital magnetism observed in twisted bilayer graphene (tBG) on nearly aligned hexagonal boron nitride (BN) substrate builds on top of the electronic structure resulting from combined G/G and G/BN double moire interfaces. Here we show that tBG/BN commensurate double moire patterns can be classified into two types, each favoring the narrowing of either the conduction or valence bands on average, and obtain the evolution of the bands as a function of the interlayer sliding vectors and electric fields. Finite valley Chern numbers $\pm 1$ are found in a wide range of parameter space when the moire bands are isolated through gaps, while the local density of states associated to the flat bands are weakly affected by the BN substrate invariably concentrating around the AA-stacked regions of tBG. We illustrate the impact of the BN substrate for a particularly pronounced electron-hole asymmetric band structure by calculating the optical conductivities of twisted bilayer graphene near the magic angle as a function of carrier density. The band structures corresponding to other $N$-multiple commensurate moire period ratios indicate it is possible to achieve narrow width $W \lesssim 30$ meV isolated folded band bundles for tBG angles $θ\lesssim 1^{\circ}$.

description: The ability to generate and control strong long-range interactions via highly excited electronic states has been the foundation for recent breakthroughs in a host of areas, from atomic and molecular physics [1, 2] to quantum optics [3, 4] and technology [5-7]. Rydberg excitons provide a promising solid-state realization of such highly excited states, for which record-breaking orbital sizes of up to a micrometer have indeed been observed in cuprous oxide semiconductors [8]. Here, we demonstrate the generation and control of strong exciton interactions in this material by optically producing two distinct quantum states of Rydberg excitons. This makes two-color pump-probe experiments possible that allow for a detailed probing of the interactions. Our experiments reveal the emergence of strong spatial correlations and an inter-state Rydberg blockade that extends over remarkably large distances of several micrometers. The generated many-body states of semiconductor excitons exhibit universal properties that only depend on the shape of the interaction potential and yield clear evidence for its vastly extended-range and power-law character.

description: We use the SYK family of models with $N$ Majorana fermions to study the complexity of time evolution, formulated as the shortest geodesic length on the unitary group manifold between the identity and the time evolution operator, in free, integrable, and chaotic systems. Initially, the shortest geodesic follows the time evolution trajectory, and hence complexity grows linearly in time. We study how this linear growth is eventually truncated by the appearance and accumulation of conjugate points, which signal the presence of shorter geodesics intersecting the time evolution trajectory. By explicitly locating such "shortcuts" through analytical and numerical methods, we demonstrate that: (a) in the free theory, time evolution encounters conjugate points at a polynomial time; consequently complexity growth truncates at $O(\sqrt{N})$, and we find an explicit operator which "fast-forwards" the free $N$-fermion time evolution with this complexity, (b) in a class of interacting integrable theories, the complexity is upper bounded by $O({\rm poly}(N))$, and (c) in chaotic theories, we argue that conjugate points do not occur until exponential times $O(e^N)$, after which it becomes possible to find infinitesimally nearby geodesics which approximate the time evolution operator. Finally, we explore the notion of eigenstate complexity in free, integrable, and chaotic models.

description: We study (3+1)D kinetic (Boltzmann-Vlasov) equations for relativistic plasma particles in a one-dimensionally expanding geometry motivated by ultrarelativistic heavy-ion collisions. We set up local equations in terms of Yang-Mills potentials and auxiliary fields that allow simulations of hard-(expanding)-loop (HEL) dynamics on a lattice. We determine numerically the evolution of plasma instabilities in the linear (Abelian) regime and also derive their late-time behavior analytically, which is consistent with recent numerical results on the evolution of the so-called melting color-glass condensate. We also find a significant delay in the onset of growth of plasma instabilities which are triggered by small rapidity fluctuations, even when the initial state is highly anisotropic.

To achieve the objectives of the study, a Language Development Estimation List was designed that consisted of two main dimensions: receptive language (25 items) and expressive language (31 items). A descriptive-comparative research approach was used to examine the differences between the teachers’ and parents’ assessments of students’ language levels according to their educational settings (special schools for deaf students or inclusive schools). This study included a purposive sample of 41 teachers and 113 parents. The teachers’ assessments showed higher receptive language scores and total scores for the inclusive school students. However, the results of the parents’ assessments showed no statistically significant differences between the students at the inclusive school and those at the school for the deaf with respect to expressive or receptive language abilities. That is, the inclusion effect remains less than desired.

description: The strong coupling between elementary excitations of the electromagnetic field (photons) and quantized mechanical vibrations (phonons) produces hybrid quasi-particle states, known as phonon-polaritons. Their typical signature is the avoided crossing between the eigenfrequencies of the coupled system, as paradigmatically illustrated by the Jaynes-Cummings Hamiltonian, and observed in quantum electrodynamics experiments where cavity photons are coupled to atoms, ions, excitons, spin ensambles and superconducting qubits. In this work, we demonstrate the generation of phonon-polaritons in the quantum motion of an optically-levitated nanosphere. The particle is trapped in high vacuum by an optical tweezer and strongly coupled to a single cavity mode by coherent scattering of the tweezer photons. The two-dimensional motion splits into two nearly-degenerate components that, together with the optical cavity mode, define an optomechanical system with three degrees-of-freedom. As such, when entering the strong coupling regime, we observe hybrid light-mechanical states with a dispersion law typical of tripartite quantum systems. Remarkably, the independent components of motion here identify a physical vibration direction on a plane that, similarly to the polarization of light, confers a vectorial nature to the polariton field. Our results pave the way to novel protocols for quantum information transfer between photonic and phononic components and represent a key-step towards the demonstration of optomechanical entangled states at room temperature.

A portrait of the artist as a Post-Hermeneutic, Neo-Kantian, transubstantiation of the de-authorized postmodern author or how I learned to stop worrying and love the jargon

description: This thesis is an interpretation and defense of Immanuel Kant's Critique of Judgment. Several commentators see in Kant's theory of beauty grave philosophical problems that cannot be rectified; consequently, they declare his entire work to be unsalvageable. I disagree with them. Through a careful analysis of his words, I attempt to recreate his arguments in the best possible light, to present them as not only intelligent and defensible in his time but in ours as well. I believe what emerges is a theory of beauty that can withstand the criticisms of radical postmodern thinkers as well as conservative traditionalists. Kant's theory allows for the significance of a work of art to be fluid, constantly changing, without also allowing that the work can mean anything at all. His account of beauty explains not only why we find certain objects beautiful, but why we also believe that others should also find the same objects beautiful. Moreover, it permits us to discuss endlessly the significance of a beautiful object without thereby committing us to there being absolute truths about the object's meaning.

description: Time-gated Förster resonance energy transfer (FRET) using the uniquematerial combination of long-lifetime terbium complexes (Tb) and semiconductor quantum dots (QDs) provides many advantages for highly sensitive and multiplexed biosensing. Although time-gated detection can efficiently suppress sample autofluorescence and background fluorescence from directly excited FRET acceptors, Tb-to-QD FRET has rarely been exploited for biomolecular imaging. We demonstrate Tb-to-QD time-gated FRET nanoassemblies that can be applied for intra- and extracellular imaging. Immunostaining of different epitopes of the epidermal growth factor receptor (EGFR) with Tb- and QD-conjugated antibodies and nanobodies allowed for efficient Tb-to-QD FRET on A431 cell membranes. The broad usability of Tb-to-QD FRET was further demonstrated by intracellular Tb-to-QD FRET and Tb-to-QD-to-dye FRET using microinjection as well as cell-penetrating peptide-mediated endocytosis with HeLa cells. Effective brightness enhancement by FRET fromseveral Tb to the sameQD, the use of lownanomolar concentrations, and the quick and sensitive detection void of FRET acceptor background fluorescence are important advantages for advanced intra- and extracellular imaging of biomolecular interactions.

description: We present an overview of unbiased studies of diffuse extragalactic radio sources. We use a previously developed filtering technique to remove compact sources from large surveys such as WENSS, WISH, and NVSS and examine the residual diffuse emission. A search of these residuals, unbiased by optical or X-ray selection, has uncovered a wide variety of diffuse sources, including those associated with groups of galaxies, ``blank'' fields, and previously unrecognized diffuse radio galaxy emission, as well as halos and relics of rich clusters. A second, targeted survey of the brightest X-ray clusters results in a number of new sources, and illuminates some important selection effects. When the well-established relationship between X-ray and radio halo luminosities is extrapolated to lower levels, the apparent correlation holds quite well for any type of diffuse source, even background noise. The observed correlations must therefore be scrutinized for possible selection effects before physical interpretations are made. We briefly mention a wide-field mapping project to search for large-scale structures, and goals for the next generation of studies in magnetic field - angular size parameter space.

description: We illustrate the benefits of combining database systems and Grid technologies for data-intensive applications. Using a cluster of SQL servers, we reimplemented an existing Grid application that finds galaxy clusters in a large astronomical database. The SQL implementation runs an order of magnitude faster than the earlier Tcl-C-file-based implementation. We discuss why and how Grid applications can take advantage of database systems.

description: In this work we focus on the dynamics of macromolecular networks formed by end-linking identical polymer stars. The resulting macromolecular network can then be viewed as consisting of spacers which connect branching points (the cores of the stars). We succeed in analyzing exactly, in the framework of the generalized Gaussian model, the eigenvalue spectrum of such networks. As applications we focus on several topologies, such as regular networks and dendrimers; furthermore, we compare the results to those found for regular hyperbranched structures. In so doing, we also consider situations in which the beads of the cores differ from the beads of the spacers. The analytical procedure which we use involves an exact real-space renormalization, which allows to relate the star-network to a (much simpler) network, in which each star is reduced to its core. It turns out that the eigenvalue spectrum of the star-polymer structure consists of two parts: One follows in terms of polynomial equations from the relaxation spectrum of the corresponding renormalized structure, while the second part involves the motion of the spacer chains themselves. Finally, we show exemplarily the situation for copolymeric dendrimers, calculate their spectra, and from them their storage and the loss moduli.
