Given a nonlinear viscoelastic (NLVE) constitutive model for a polymer, this numerical study aims at simulating local stress concentrations in a boundary value problem with a corner stress singularity. A rectangular sample of Polyvinyl Acetate (PVAc)-like cross-linked polymer clamped by two metallic rigid grips and subjected to a compression and tension load is numerically simulated.

A modified version of the finite element code FEAP, that incorporated a NLVE model based on the free volume theory, was used. First, the program was validated by comparing numerical and analytical results. Two simple mechanical tests (a uniaxial and a simple shear test) were performed on a Standard Linear Solid material model, using a linear viscoelastic (LVE) constitutive model. The LVE model was
obtained by setting the proportionality coefficient [...] to zero in the free volume theory equations. Second, the LVE model was used on the corner singularity boundary value problem for three material models with different bulk relaxation functions K(t). The time-dependent stress field distribution was investigated using two sets of plots: the stress distribution contour plots and the stress time curves. Third, using the NLVE constitutive model, compression and tension cases were compared using the stress results (normal stress [...] and shear stress [...]). These two cases assessed the effect of the creep retardation-creep acceleration phenomena.

The shift between the beginning of the relaxation moduli was shown to play an important role. This parameter affects strongly the fluctuation pattern of the stress curves. For two different shift values, in one case, the stress response presents a 'double peak' and 'stress inversion' characteristic whereas, in the other case, it presents a 'single peak' and no 'inversion'. Another important factor was the material's compressibility. In the case of a nearly-incompressible material, the LVE and NLVE models yielded identical results; thus, the simpler LVE model is preferable.

However, in the case of sufficient volume dilatation (or contraction), the NLVE model predicted correct characteristic responses, whereas LVE results were erroneous.  This proves the necessity of using the NLVE model over the LVE model.

description: A large class of symmetry-protected topological phases (SPT) in boson / spin systems have been recently predicted by the group cohomology theory. In this work, we consider SPT states at least with charge symmetry (U(1) or Z$_N$) or spin $S^z$ rotation symmetry (U(1) or Z$_N$) in 2D, 3D, and the surface of 3D. If both are U(1), we apply external electromagnetic field / `spin gauge field' to study the charge / spin response. For the SPT examples we consider (i.e. U$_c$(1)$\rtimes$Z$^T_2$, U$_s$(1)$\times$Z$^T_2$, U$_c$(1)$\times$[U$_s$(1)$\rtimes$Z$_2$]; subscripts $c$ and $s$ are short for charge and spin; Z$^T_2$ and Z$_2$ are time-reversal symmetry and $π$-rotation about $S^y$, respectively), many variants of Witten effect in the 3D SPT bulk and various versions of anomalous surface quantum Hall effect are defined and systematically investigated. If charge or spin symmetry reduces to Z$_N$ by considering charge-$N$ or spin-$N$ condensate, instead of the linear response approach, we gauge the charge/spin symmetry, leading to a dynamical gauge theory with some remaining global symmetry. The 3D dynamical gauge theory describes a symmetry-enriched topological phase (SET), i.e. a topologically ordered state with global symmetry which admits nontrivial ground state degeneracy depending on spatial manifold topology. For the SPT examples we consider, the corresponding SET states are described by dynamical topological gauge theory with topological BF term and axionic $Θ$-term in 3D bulk. And the surface of SET is described by the chiral boson theory with quantum anomaly.

description: Numerous cell-types have shown a remarkable ability to detect and move along gradients in stiffness of an underlying substrate -- a process known as durotaxis. The mechanisms underlying durotaxis are still unresolved, but generally believed to involve active sensing and locomotion. Here, we show that simple liquid droplets also undergo durotaxis. By modulating substrate stiffness, we obtain fine control of droplet position on soft, flat substrates. Unlike other control mechanisms, droplet durotaxis works without imposing chemical, thermal, electrical or topographical gradients. This enables a new approach to large-scale droplet patterning and is potentially useful for many applications, such as microfluidics, thermal control and microfabrication.
Uncertainty Quantification in Simulation-based Inference

Publisher: name: Carnegie Mellon University
Year: 2021
Subjects: subject: Statistics
subject: FOS: Mathematics

description: Complex phenomena in engineering and the sciences are often modeled by feed-forward simulators that implicitly encode the likelihood function. Classical methods for constructing confidence sets and hypothesis tests are poorly suited for such settings. While the field of simulation-based inference has undergone a revolution in terms of the complexity of problems that can be tackled, the development on the statistical methodology front has fallen behind. Indeed, many techniques have been developed for learning a surrogate likelihood using forward-simulated data, but these methods do not guarantee frequentist confidence sets and tests with nominal coverage and Type I error control, respectively, outside the asymptotic and low-dimensional regimes. In this thesis we introduce a series of statistical tools for uncertainty quantification in a simulation-based inference setting. In the first part of the thesis, we provide inferential tools with frequentist guarantees for a high-dimensional simulator-based setting. We introduce a statistical framework that unifies classical statistics with modern machine learning algorithms to achieve the followinggoals: (i) confidence sets and hypothesis tests with finite-sample guarantees of coverage and power, (ii) diagnostics for checking empirical coverage over the entire parameter space and (iii) scalable and modular procedure which can also be used with other simulation-based approaches. We showcase the applicability of this framework across a diverse range of data and parameter settings. In the second part of the thesis, we consider the problem of assessing the quality of fit of approximate likelihood models. Approximate likelihood models are used in settings with high-resolution and computationally intensive simulators for faster inference. We propose a statistically consistent validation method that can pinpoint the locations in the parameter space where the fit is inadequate as well as provide insights as to how the high-resolution simulator and approximate likelihood model differ In the third and final part of the thesis, we propose a new flexible method for nonparametric conditional density estimation that can transform any neural networkregression architecture into a conditional density estimator. We demonstrate the versatility of our approach for two applications with convolutional and recurrent neural networks, respectively.
title: Predicting E-Cigarette Use Among Emerging Adults Using Perceived Social Norms and Outcome Expectancies
Creators: name: Hanson, Stephen N.
Publisher: name: Old Dominion University Libraries

description: Despite low rates of combustible tobacco use rates among adolescents and young adults, e-cigarettes continue to gain popularity. A few factors have been shown to be related to e-cigarette use based on prior research. One such example is social enhancement expectancies. Additionally, greater perceptions of harm have been found to be inversely related to e-cigarette use such that those that expect increased risk to their health are less likely to report using e-cigarettes. I hypothesized that social enhancement expectancies would mediate the relationship between perceptions of social norms and e-cigarette dependence. I also hypothesized that perceived harm, such as greater perceived health risks, would moderate the indirect effect of perceived social norms and e-cigarette dependence. The same analyses were also examined with a dichotomous e-cigarette user status outcome variable. E-cigarette use status was determined based on past 30- day use of e-cigarettes. Analyses revealed that injunctive norms emerged as a significant predictor of both positive social outcome expectancies and e-cigarette user status. Perceived harm was also found to be a significant predictor of e-cigarette dependence. Further exploration of within group differences among e-cigarette users may be warranted in order to develop an intervention strategy tailored to this group.

description: The interaction of the Sulfonic Acid Resin,
Nalcite HCR, with CuII halide solutions was studied
in hope of obtaining dissociation constants for the complex
ions CuX+. The fact that CuX+ is absorbed by
the resin to an appreciable extent prevented the
attainmnet of this goal. It was found in the case of
CuF+ that the complex ion is absorbed even more strongly
than Cu++. The presence of a Cu++-F- complex
was indicated by spectrophotometric observations.

The action of the carboxylic acid resin, IRC - 50
was studied in a column. It was found that the
volume of the resin in the Cu++ salt form depended
on the salt with which the resin was treated. In the
case of solutions of Cu(OAc)2 it was found that Cu(OAc)+
was taken into the resin as well as Cu++.

A titration curve for IRC - 50 with NaOH in
solutions of ionic strength one is given.

description: Using the S-matrix for the d(2,1;alpha)^2 symmetric spin-chain of AdS3/CFT2, we propose a new set of all-loop Bethe equations for the system. These equations differ from the ones previously found in the literature by the choice of relative grading between the two copies of the d(2,1;alpha) superalgebra, and involve four undetermined scalar factors that play the role of dressing phases. Imposing crossing symmetry and comparing with the near-BMN form of the S-matrix found in the literature, we find several novel features. In particular, the scalar factors must differ from the Beisert-Eden-Staudacher phase, and should couple nodes of different masses to each other. In the semiclassical limit the phases are given by a suitable generalization of Arutyunov-Frolov-Staudacher phase.

Teaching Teams to Innovate: The Successful Transfer of Difference-Driven Inquiry from the Workplace to the Classroom
Creators: name: Moreau, Craig
Publisher: name: Carnegie Mellon University
Year: 2021
Subjects: Rhetoric

description: Teams that can leverage diverse perspectives demonstrate a powerful way to stimulate innovative ways of thinking and doing. Commonly, innovation is facilitated through toolsets informed by design-thinking, from techniques to facilitate brainstorming like mind-mapping and whiteboarding, to more advanced agile techniques like prototyping and user-testing. However, the use of these ideational tools to promote innovation often assumes high levels of team cohesion and productivity—dynamics that may not be safe to assume, especially in teams with high levels of diversity. Furthermore, when teams attempt to add depth or find alternatives to ideas already voiced, individuals often must find ways of resisting the formidable social forces of groupthink and entrenchment. One of the most powerful resources to counter those forces includes engaging in what scholars have named as substantive or productive conflict (Burnett, 1996; Cronin & Weingart, 2007).This dissertation study takes a rhetorical approach to understanding how productive conflict can benefit teams seeking to innovate. Building from Flower’s (2016) working theory of Difference-Driven Inquiry—a process of deliberation that aims to voice difference and embrace conflict—this dissertation uses empirical methods to offer a descriptive account of, and a prescriptive pedagogy for, a model to help people embrace the generative aspects of conflict as they seek novel solutions to problems.In broad terms, this dissertation contributes to technical and professional communication by observing, creating, and enhancing a novel pedagogy to help students and practitioners alike approach teamwork as a deliberative process that values difference as a rich source for rhetorical invention.

The determination of sound velocity in core samples

Publisher: name: California Institute of Technology
Year: 1939
Subjects: subject: Geology
subject: FOS: Earth and related environmental sciences

description: In an area that is being explored for the first time
with the reflection seismograph, the manner in which the longitudinal wave velocity varies with depth---the so-called "velocity distribution"---is unknown. Structural features can be located without a knowledge of this function, but they cannot be measured. In the present advanced state of reflection seismology more than mere detection of structural detail is necessary. And in order to compute dips and depths from the reflections and thereby obtain a quantitative structural picture, the velocity
distribution has to be known with a tolerably decent degree
of accuracy.

There are in common use at present two methods of velocity distribution determination. The more direct of these consists simply of lowering a seismometer to successively different depths down a well already drilled, shooting at the surface near the casing head, and observing the travel times of the first impeti from the records. This method is simple, direct, and without doubt gives the best possible determination of velocity distribution. It necessitates, however, a well that is available for use in this way, as well as the expense of running a seismograph crew for a day or two. The second method of velocity
measurement involves only surface shooting and recording. Travel time differences for different shooting distances are carefully measured from surface records of several hundred reflections, plotted, and an average velocity computed. This method involves a great amount of computing and inconveniences resulting from the fact that considerable shooting has to be done in an area before the velocity distribution becomes to be known.

Some sort of inexpensive laboratory measurement of
velocity would apparently, therefore, be of value. Important
wildcat wells of major companies are now being more or less
continuously cored. If the sound velocity in representative
samples of the corings at different depths could be measured
some idea of the velocity-depth function might be obtained.
It is the purpose of this thesis to examine the correlation,
if any, between the velocity distribution as obtained in the
customary manner as described above, and that obtained from
laboratory measurement of velocity in core samples from a well in the same area.

description: We present the discovery of an isolated compact elliptical (cE) galaxy, found during a search of SDSS DR7 for cEs, and for which we obtained WHT/ACAM imaging. It is ~900 kpc distant from its nearest neighbour, has an effective r-band radius of ~500 pc and a B-band mean surface brightness within its effective radius of 19.75 mag/arcsec. Serendipitous deep SuprimeCam imaging shows that there is no underlying disk. Its isolated position suggests that there is an alternative channel to the stripping scenario for the formation of compact ellipticals. We also report analysis of recent deeper imaging of the previous candidate free-flying cE, which shows that it is, in fact, a normal dwarf elliptical (dE). Hence the new cE reported here is the first confirmed isolated compact elliptical to be found in the field.

description: In this paper, we propose some representations of a generalized linear birth process called fractional Yule process (fYp). We also derive the probability distributions of the random birth and sojourn times. The inter-birth time distribution and the representations then yield algorithms on how to simulate sample paths of the fYp. We also attempt to estimate the model parameters in order for the fYp to be usable in practice. The estimation procedure is then tested using simulated data as well. We also illustrate some major characteristics of fYp which will be helpful for real applications.
Lungs function in relation to exposure to cotton dust in a Hosiery section of a Textiles Plant in Punjab, Pakistan

description: This study aimed at determining whether exposures to organic dusts were associated with decreases in lungs function among workers exposed to cotton dust in a hosiery unit manufacturing pure cotton garments. In a cross-sectional study, 287 employees underwent lungs function testing in accordance with the National Institute of Occupational Safety and Health (NIOSH) spirometric guidelines. Workers were selected with the help of stratified random sampling of age 19–50 years (participation rate 82.0%). A modified NIOSH questionnaire was used to elicit information from them. We also measured personal dust and fine particulates (aerodynamic diameter of 2.5 micron and less, PM2.5) in the working areas near the workers, and these pollutants were measured using a personal dust sampler and a DustTrakTM, respectively. Concentrations of total dust and PM2.5 varied among the different areas of a hosiery plant. The deleterious effects of cotton dust were higher in smokers than non-smoker workers. An association between exposures to cotton dust and to PM2.5 and lungs function in the study population were found. This study shows association with lungs function arising from exposure to organic dust and PM2.5.

description: Finding the densest sphere packing in $d$-dimensional Euclidean space $\mathbb{R}^d$ is an outstanding fundamental problem with relevance in many fields, including the ground states of molecular systems, colloidal crystal structures, coding theory, discrete geometry, number theory, and biological systems. Numerically generating the densest sphere packings becomes very challenging in high dimensions due to an exponentially increasing number of possible sphere contacts and sphere configurations, even for the restricted problem of finding the densest lattice sphere packings. In this paper, we apply the Torquato-Jiao packing algorithm, which is a method based on solving a sequence of linear programs, to robustly reproduce the densest known lattice sphere packings for dimensions 2 through 19. We show that the TJ algorithm is appreciably more efficient at solving these problems than previously published methods. Indeed, in some dimensions, the former procedure can be as much as three orders of magnitude faster at finding the optimal solutions than earlier ones. We also study the suboptimal local density-maxima solutions (inherent structures or "extreme" lattices) to gain insight about the nature of the topography of the "density" landscape.

description: The region treated in the following report is a small area of about one square mile near Pacoima, California.  It consists of a group of small hills that that form the western abutment of the Hansen Dam.  It is underlain by a section of intrusives, sediments, and extrusives, which may be subdivided into four groups.

The oldest rocks form the Dimebere complex of Jurassic (?) plutonic rocks, pegmatites, and schists.  Lying uncomformably on this is a series of alternating terrestrial sandstones and bassalts of Tertiary age.  These are unconformably overlain in turn by the Hansen Dam formation, a series of marine shales and sandstone correlated with the Temblor by the fossil contact.  Finally into these strata was intruded the Munglish andesite.

These strata form a shallow, plunging anticline, whose axis trends slightly east of north and lies in the center of the hills.  The unconformities have been offset in several places by a series of faults apparently related to the anticline.

A complete outline of the geologic history is included in the report.

description: We stabilize nematic droplets with handles against surface-tension-driven instabilities using a yield-stress material as outer fluid and study the complex nematic textures and defect structures that result from the competition between topological constraints and the elasticity of the nematic liquid crystal. We uncover a surprisingly persistent twisted configuration of the nematic director inside the droplets when tangential anchoring is established at their boundaries, which we explain after considering the influence of saddle-splay on the elastic free energy. For toroidal droplets, we find that the saddle-splay energy screens the twisting energy resulting in a spontaneous breaking of mirror symmetry; the chiral twisted state persists for aspect ratios as large as ~20. For droplets with additional handles, we observe in experiments and computer simulations that there are two additional -1 surface defects per handle; these are located in regions with local saddle geometry to minimize the nematic distortions and hence the corresponding elastic free energy.

description: We describe a fully ultra-high vacuum compatible scanning tunneling microscope (STM) optimized for radio-frequency signals. It includes in-situ exchangeable tips adapted to high frequency cabling and a standard sample holder, which offer access to the whole range of samples typically investigated by STM. We demonstrate a time resolution of 120 ps using the nonlinear I(V)-characteristic of the surface of highly oriented pyrolithic graphite. We provide atomically resolved images in pulse mode related to a spatially varying nonlinearity of the local density of states of the sample, thus, demonstrating the possible spatial resolution of the instrument in pulse mode. Analysis of the noise reveals that changes in the tunneling junction of 50 pA are dynamically detectable at 120 ps time resolution.

description: In this third chapter of my book Dead Men Rising: The Death of Sin and the Rise of Grace in Romans 6:1-14, I examine four issues: the death of Christ language, baptism, the phrase once for all, and the idea of death as master. The examination of these topics brings the reader closer to what Paul's mind when he spoke of the Christian's death to sin. The key point of this chapter is that Whatever death to sin means, it can mean nothing more or nothing less than what it meant to Christ. We died to sin only because Christ died to sin. The reader should also keep in mind that the chapters build on one another. Footnotes do not begin with "1" but are progressive from the previously published paper (chapter). Some footnotes may refer to authors and their books that are mentioned in the previous pages. I recommend that the reader read the previous chapters to gain the full context.

description: Because of the temporal incoherence of sunlight, solar cells efficiency should depend on the degree of coherence of the incident light. However, numerical computation methods, which are used to optimize these devices, fundamentally consider fully coherent light. Hereafter, we show that the incoherent efficiency of solar cells can be easily analytically calculated. The incoherent efficiency is simply derived from the coherent one thanks to a convolution product with a function characterizing the incoherent light. Our approach is neither heuristic nor empiric but is deduced from first-principle, i.e. Maxwell's equations. Usually, in order to reproduce the incoherent behavior, statistical methods requiring a high number of numerical simulations are used. With our method, such approaches are not required. Our results are compared with those from previous works and good agreement is found.

Intermittency in 2D soap film turbulence

description: The Reynolds number dependency of intermittency for 2D turbulence is studied in a flowing soap film. The Reynolds number used here is the Taylor microscale Reynolds number R_λ, which ranges from 20 to 800. Strong intermittency is found for both the inverse energy and direct enstrophy cascades as measured by (a) the pdf of velocity differences P(δu(r)) at inertial scales r, (b) the kurtosis of P(\partial_x u), and (c) the scaling of the so-called intermittency exponent μ, which is zero if intermittency is absent. Measures (b) and (c) are quantitative, while (a) is qualitative. These measurements are in disagreement with some previous results but not all. The velocity derivatives are nongaussian at all R_λ but show signs of becoming gaussian as R_λ increases beyond the largest values that could be reached. The kurtosis of P(δu(r)) at various r indicates that the intermittency is scale dependent. The structure function scaling exponents also deviate strongly from the Kraichnan prediction. For the enstrophy cascade, the intermittancy decreases as a power law in R_λ. This study suggests the need for a new look at the statistics of 2D turbulence.

description: We report on the enhancement of surface plasmon resonances in a holey bidimensional grating of subwavelength size, drilled in a gold thin film coated by a graphene sheet. The enhancement originates from the coupling between charge carriers in graphene and gold surface plasmons. The main plasmon resonance peak is located around 1.5 microns. A lower constraint on the gold-induced doping concentration of graphene is specified and the interest of this architecture for molecular sensing is also highlighted.

REVEALING ZEBRAFISH EMBRYONIC DEVELOPMENTAL BIOELECTRICITY USING GENETICALLY ENCODED TOOLS

Subjects: Cell development, proliferation and death

description: Bioelectricity, or endogenous electrical signaling mediated by the dynamic distribution of charged molecules, is an ancient signaling mechanism conserved across living organisms. Increasing evidence has revealed that bioelectric signals play a critical role in many diverse aspects of biology such as embryonic development, cell migration, regeneration, cancer, and other diseases. However, direct visualization and manipulation of bioelectricity during development are lacking. Neuroscience has developed tools such as GEVIs (genetically encoded voltage indicators) and chemogenetics like DREADDs (designer receptor exclusively activated by designer drugs) which allow for real–time voltage monitoring and activation of mutated receptors by inert molecules for perturbing membrane potential (Vm). To uncover bioelectric activity during development, we generated a whole-zebrafish transgenic GEVI reporter line and characterized the electrical signaling during early embryogenesis using light sheet microscopy (LSM). Additionally, we generated tissue-specific transgenic lines that combined GEVIs and chemogenetic DREADD tools to manipulate Vm. We found zebrafish embryos display stage-specific characteristic bioelectric signals during the cleavage, blastula, gastrula, and segmentation periods. Furthermore, activation of DREADDs was able to alter cell-specific GEVI fluorescence intensity and could cause a melanophore hyperpigmentation phenotype. Ultimately, these results provide the first real-time systematic analysis of endogenous bioelectricity during vertebrate embryonic development. Additionally, we generated and tested zebrafish transgenic lines for simultaneous visualization and chemogenetic manipulation of Vm during development. These results provide a better understanding of developmental bioelectricity and new tools for future studies, which could eventually help uncover the cellular electric mechanisms behind tissue patterning and disease.
