The Cancerous Breast: Establishing Illness as an Opportunity to Help Others
Creators: name: Pogson, Kaylyn Beatrice
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2017

description: As of 2017, about one in eight women living in the United States will develop invasive
breast cancer of the course of her lifetime. Fortunately, the chances for men are much lower,
about one in one thousand. Thus, there is a reason breast cancer is associated with the color
pink, which is the hue linked with femininity in modern Western society. Breast cancer is pink in
the Western cultural consciousness because it is an innately gendered disease, and it has been
afflicting the lives of women for thousands of years. The nature of the medicine used to treat
breast cancer has changed over time, and accordingly, the experience of having breast cancer has
as well. Medicine, attitudes, thought, and knowledge about breast cancer have all morphed with
time due to research and activism, but there are some fundamental qualities that resist evolution.
The changing and unchanging qualities of the breast cancer experience can be parsed from the
narratives of women who have been afflicted by the disease. In addition, narratives can also
reveal the wide variety of possible ways to conceptualize and cope with having breast cancer,
with each method no less effective or valid than the last.
One of the most interesting fundamental qualities is the drive that many women with
breast cancer possess to share their experiences through narrative. Breast cancer narratives are
relatively common in today’s world, with many women choosing to write about what they went
through during the diagnosis and treatment processes. However, this narration and desire to share
is hardly a new phenomenon. As early as 1811, Frances Burney wrote about her mastectomy in a
letter to her sister, describing her experience and relaying her thought process throughout the
ordeal in an early version of an illness narrative. There is something distinct that tends to occur
in breast cancer narratives, through their actions in the story and their words expressing their
thoughts and concerns, women with breast cancer display an extraordinary desire to help and
protect others. They strive to protect their families from having to endure more emotional agony
than is absolutely necessary, and they advise their readers on methods to have a less hurtful
encounter with the disease. Breast cancer narratives tend to reflect the different time periods in
which they are written by being constructed in different genres, often either a common or a new
genre of the time. Burney wrote her narrative in the form of a letter, while Jennifer Ho writing in
the 21st century utilized the blog form. No matter the genre, community, agency, and identity are
established as recurrent themes in the work of women with breast cancer as they utilize new
forms of writing available to them to express their illness narratives in the hopes that each
woman after her will have to suffer less than those before.

description: The frequency noise power spectral density of a free-running quantum cascade laser frequency comb is investigated. A plateau is observed at high frequencies, attributed to the quantum noise limit set by the Schawlow-Townes formula for the total laser power on all comb lines. In our experiment, a linewidth of 292 Hz is measured for a total power of 25 mW. This result proves that the four-wave mixing process, responsible for the comb operation, effectively correlates the quantum noise of the individual comb lines.

description: Optical metasurfaces have been recently explored as ultrathin analog image differentiators. By tailoring the momentum transfer function, they can perform efficient Fourier-filtering - and thus potentially any linear mathematical operation - on an input image, replacing bulky 4f systems. While this approach has been investigated in different platforms, and several techniques have been explored to achieve the required angular response, little effort has been devoted so far to tailor and control also the polarization response of an image-processing metasurface. Here, we show that edge-detection metasurfaces can be designed with tailored polarization responses while simultaneously preserving an isotropic response. In particular, we demonstrate single-layer silicon metasurfaces yielding efficient Laplacian operation on a 2D image with either large polarization asymmetry, or nearly polarization-independent response. In the former case, we show that a strongly asymmetric polarization response can be used to unlock more sophisticated on-the-fly image processing functionalities, such as dynamically tunable direction-dependent edge detection. In parallel, metasurfaces with dual-polarized response are shown to enable efficient operation for unpolarized or arbitrarily polarized images, ensuring high efficiency. For both devices, we demonstrate edge detection within relatively large numerical apertures, with excellent isotropy and intensity throughput. Our study paves the way for the broad use of optical metasurfaces for sophisticated, massively parallel analog image processing with zero energy requirements.

A Study of Doctors' Decision-Making and Doctor-Patient Interactions
Creators: name: Dewolf, Jessica
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2015

description: The purpose of this study is to analyze the decision-making practices of cancer doctors, including how those decisions impact the identity construction and sensemaking practices of patients. I look at how doctors make ethical decisions regarding patient interaction and treatment by examining processes of decision-making. More specifically, I study how doctors navigate personal motivation and institutional structures when making their decisions. I also examine how doctors make decisions regarding the type and amount of treatment to provide to patients, as well as how doctors negotiate the risks associated with treating cancer patients.
The project examines the ethical issues that exist within the medical field, including the ethical principles which govern doctor-patient interaction. It studies why ethics is important to the medical field, how doctors confront ethical dilemmas, and how their decisions may impact patient health. In addition to this focus on ethics, the project considers how patients are impacted by doctor decisions and interaction, and whether or not patient identity and sensemaking practices are affected by the ethical decisions of doctors. I will focus specifically on end-of-life scenarios involving cancer diagnoses.

description: This review systematically gathers and provides an analysis of pollutants levels emitted from wildfire (WF) and their impact on short-term health effects of affected populations. The available literature was searched according to Population, Exposure, Comparator, Outcome, and Study design (PECOS) database defined by the World Health Organization (WHO) and a meta-analysis was conducted whenever possible. Data obtained through PECOS characterized information from the USA, Europe, Australia, and some Asian countries; South American countries were seldom characterized, and no data were available for Africa and Russia. Extremely high levels of pollutants, mostly of fine fraction of particulate matter (PM) and ozone, were associated with intense WF emissions in North America, Oceania, and Asia and reported to exceed several-fold the WHO guidelines. Adverse health outcomes include emergency department visits and hospital admissions for cardiorespiratory diseases as well as mortality. Despite the heterogeneity among exposure and health assessment methods, all-cause mortality, and specific-cause mortality were significantly associated with WF emissions in most of the reports. Globally, a significant association was found for all-cause respiratory outcomes including asthma, but mixed results were noted for cardiovascular-related effects. For the latter, estimates were only significant several days after WF emissions, suggesting a more delayed impact on the heart. Different research gaps are presented, including the need for the application of standardized protocols for assessment of both exposure and adverse health risks. Mitigation actions also need to be strengthened, including dedicated efforts to communicate with the affected populations, to engage them for adoption of protective behaviors and measures.

description: Building energy prediction and management has become increasingly important in recent decades, driven by the growth of Internet of Things (IoT) devices and the availability of more energy data. However, energy data is often collected from multiple sources and can be incomplete or inconsistent, which can hinder accurate predictions and management of energy systems and limit the usefulness of the data for decision-making and research. To address this issue, past studies have focused on imputing missing gaps in energy data, including random and continuous gaps. One of the main challenges in this area is the lack of validation on a benchmark dataset with various building and meter types, making it difficult to accurately evaluate the performance of different imputation methods. Another challenge is the lack of application of state-of-the-art imputation methods for missing gaps in energy data. Contemporary image-inpainting methods, such as Partial Convolution (PConv), have been widely used in the computer vision domain and have demonstrated their effectiveness in dealing with complex missing patterns. To study whether energy data imputation can benefit from the image-based deep learning method, this study compared PConv, Convolutional neural networks (CNNs), and weekly persistence method using one of the biggest publicly available whole building energy datasets, consisting of 1479 power meters worldwide, as the benchmark. The results show that, compared to the CNN with the raw time series (1D-CNN) and the weekly persistence method, neural network models with reshaped energy data with two dimensions reduced the Mean Squared Error (MSE) by 10% to 30%. The advanced deep learning method, Partial convolution (PConv), has further reduced the MSE by 20-30% than 2D-CNN and stands out among all models.
A Fractal Perspective on Scale in Geography

Subjects: subject: History and Overview (math.HO)
subject: FOS: Mathematics

description: Scale is a fundamental concept that has attracted persistent attention in geography literature over the past several decades. However, it creates enormous confusion and frustration, particularly in the context of geographic information science, because of scale-related issues such as image resolution, and the modifiable areal unit problem (MAUP). This paper argues that the confusion and frustration mainly arise from Euclidean geometric thinking, with which locations, directions, and sizes are considered absolute, and it is time to reverse this conventional thinking. Hence, we review fractal geometry, together with its underlying way of thinking, and compare it to Euclidean geometry. Under the paradigm of Euclidean geometry, everything is measurable, no matter how big or small. However, geographic features, due to their fractal nature, are essentially unmeasurable or their sizes depend on scale. For example, the length of a coastline, the area of a lake, and the slope of a topographic surface are all scale-dependent. Seen from the perspective of fractal geometry, many scale issues, such as the MAUP, are inevitable. They appear unsolvable, but can be dealt with. To effectively deal with scale-related issues, we introduce topological and scaling analyses based on street-related concepts such as natural streets, street blocks, and natural cities. We further contend that spatial heterogeneity, or the fractal nature of geographic features, is the first and foremost effect of two spatial properties, because it is general and universal across all scales. Keywords: Scaling, spatial heterogeneity, conundrum of length, MAUP, topological analysis

description: Computing checksums to prevent bit rot is accepted wisdom in the digital preservation community. Yet in other domains, this wisdom is approached quite differently. New hashing algorithms continue to be developed in the cryptography community, typically with very different use cases in mind, focusing on encryption and security over integrity or identification. Checksumming is also a key feature of modern filesystems. The implementers of these filesystems concern themselves with block-level integrity, rather than focus on ‘files’ or objects in the way digital preservation systems do. Cloud-based object storage systems also compute checksums, providing integrity guarantees as part of the service. And there is the blockchain - distributed peer to peer systems where hashing is fundamental. How do we reconcile these different approaches to bit-level preservation using checksums? Can we compare the costs, in terms of compute resources or time, of the different approaches? Is there a way to verify the accepted wisdom of the digital preservation community and reconcile this with the diverse and expanding approaches to checksum validation? This paper describes how checksumming functionality is understood and implemented in modern filesystems. A cost analysis is presented, comparing different approaches to data integrity, including pure CPU checksumming with tools such as md5sum, the block-level metadata used by filesystems such as ZFS, and the contrast with data integrity done by cloud service providers’ object storage services. From this analysis we describe the benefits of developing a new standard for mapping the block-level metadata produced by filesystem checksum reporting tools to the file-centered checksum reporting and validation required for adherence to current expectations of accepted digital preservation best practices. By better understanding different approaches to data integrity, it is possible to make better use of the computer hardware dedicated to digital preservation, taking advantage of the increased computational efficiency of filesystem-level checksumming techniques. This work closes a gap between current best practices in digital preservation and in high-performance computing. Sample code paths for working with and validating block checksums are also demonstrated.
Conceptual Design for a Small Modular Nuclear Reactor in an Urban Environment

Year: 2014

description: Given the worldwide necessity to reduce anthropogenic contributions to global
climate change, an increased focus on nuclear energy over traditional fossil fuel based
sources is arguably justified. This paper attempts to analyze whether it is possible for
small modular nuclear reactors in particular to contribute to that transition, specifically
through their utilization in an urban environment. For this analysis, an urban setting is
defined as a large American university that currently produces a portion of its
electricity demand at an onsite cogeneration facility. The University of North Carolina
at Chapel Hill is used as a basic model for this university setting in this analysis. All
relevant considerations were evaluated to determine overall feasibility of potential SMR
implementation in this setting, as well as the requirements for specific design selection.
Based on these requirements, three models were selected for further analysis: SVBR‑100,
TWR‑P, and EM2. All three were found to be suitable for university implementation,
thus confirming the overall feasibility of SMR implementation in the described urban
setting. While the most appropriate model depends on the specific inputs to the
developed ranking system (which can be adjusted for various potential universities),
overall EM2 and TWR‑P can be considered the more suitable of the three.

description: The Oxford Common File Layout (OCFL) initiative is an effort to define a shared approach to file hierarchy for long-term preservation. What began as a discussion at the Fedora and Samvera Camp held in Oxford, UK in September of 2017 has grown into a focused community effort. Many repository systems store large amounts of data that are difficult to migrate, and such migrations risk data loss. Within a storage system, digital objects should be designed under the assumption that they will be accessed and managed by a variety of applications. This effort is an attempt to decouple the structure of the persisted files from the software that might manage it by creating an expectation of file hierarchy to which software applications must conform, whether implemented in a conventional filesystem with files and directories, or in an object store. Thus the file hierarchy functions as a storage Application Programming Interface (API). This effort addresses three primary requirements: 1) completeness, so that a repository can be rebuilt from the files, 2) parsability, both by humans and machines in the absence of original software, and 3) robustness against errors, corruption and migration between storage technologies. This paper describes motivations, principles and anticipated features of the proposed file layout. The OCFL initiative aims to produce draft specifications for trial use by Fall 2018.
Stability of Schwarzshild black holes in quadratic gravity with Weyl curvature domination

description: We study the linear stability of static and spherically symmetric (SSS) black holes (BHs) in the presence of a Weyl-squared curvature besides an Einstein-Hilbert term in the action. In this theory, there is always an exact Schwarzschild BH irrespective of the Weyl coupling constant $α$, with the appearance of a non-Schwarzschild solution for a particular range of the coupling of order $|α| \approx r_h^2$ (where $r_h$ is the horizon radius). On the SSS background, we show that the propagating degrees of freedom (DOFs) are three in the odd-parity sector and four in the even-parity sector. Since the number of total seven DOFs coincides with those on the Minkowski and isotropic cosmological backgrounds, the Weyl gravity does not pose a strong coupling problem associated with the vanishing kinetic term of dynamical perturbations. The odd-parity perturbations possess at least one ghost mode, but the propagation speeds of all three dynamical modes are luminal. In the even-parity sector, our analysis, based on the WKB approximation, shows that, besides the appearance of at least one ghost mode, the Schwarzschild solution is prone to both radial and angular Laplacian instabilities of several dynamical perturbations for the Weyl coupling in the range $|α| \gg r_h^2$. For large radial and angular momentum modes, the time scales of such instabilities are much shorter than the horizon distance $r_h$ divided by the speed of light. In the coupling regime $|α|\lesssim r_h^2$, the WKB approximation does not hold any longer, and a different analysis should be performed if one wants to state the stability of both the Schwarzschild and non-Schwarzschild BH solutions in this range of model parameters.

description: The main physics goals of the NA61/SHINE programme on strong interactions are the study of the properties of the onset of deconfinement and the search for signatures of the critical point of strongly interacting matter. These goals are pursued by performing an energy (beam momentum 13A -158A GeV/c) and system size (p+p, p+Pb, Be+Be, Ar+Sc, Xe+La) scan. This publication reviews results and plans of NA61/SHINE. In particular, recent inclusive spectra and new results on fluctuations and correlations of identified hadrons in inelastic p+p and centrality selected Be+Be interactions at the SPS energies are presented. The energy dependence of quantities inspired by the Statistical Model of the Early Stage (kink, horn and step) show unexpected behavior in p+p collisions. The NA61/SHINE results are compared with the corresponding data of other experiments and model predictions.
Investigating Feedbacks between Sediment Dynamics and Oyster Growth Using an Idealized Differential Equation Model
Creators: name: Housego, Rachel
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2014

description: Sedimentation has been identified as an important factor that can limit oyster reef restoration success. Previous field studies have demonstrated that high relief reefs are more productive and resilient to disturbance than low relief reefs, in part because increasing the reef height can reduce sedimentation and enhance oyster growth. In this study we investigated the relationship between initial reef height and reef survival using a simple model. The model, based on Jordan-Cooley et al. (2011), contains three coupled differential equations that describe changes in oyster volume, sediment volume, and shell volume per unit area of reef with time. In our study, the terms for oyster growth, sediment deposition, and erosion were modified from the Jordan-Cooley model to better represent these processes. A sensitivity analysis was then performed to investigate the ways in which parameters such as flow speed, sediment grain size, and ambient food concentration affect model results. Our results suggest that the shape of the sediment concentration profile in the water column relative to the initial reef height is important for determining whether a reef will survive. Parameters that describe oyster growth will control the productivity of the reef and the final reef height, if the reef does survive. Therefore, our study creates a tool that can be used to predict the relative success of restored oyster reefs under different environmental conditions and the impact of different physical parameters on reef restoration success.

Driven by the main principle of adherence to the PREMIS Data Dictionary, and a set of well-established Linked Data principles, the draft release of the PREMIS 3 OWL ontology comes after two years of conceptualization, discussion and experi- mentation. The release of the draft was followed by a public review of the revised ontology soliciting a wider discussion about the con- ceptual choices expressed by the ontology. This article explains how interoperability issues have been addressed, with the intent of maintaining continuity between the PREMIS Data Dictionary and the PREMIS OWL ontology.

description: We describe in this paper the observables of inflationary models, in particular the spectrum index of torsion scalar perturbations, the tensor-to-scalar ratio, and the running of the spectral index, in the framework of perfect fluid models and F(T) gravity theories through the reconstruction methods. Then, our results on the perfect fluid and F(T) gravity theories of inflation are compared with recent cosmological observations such as the Planck satellite and BICEP2 experiment. Ours studies prove that the perfect fluid and F(T) gravity models can reproduce the inflationary universe consistent above all with the Planck data. We have reconstructed several models and considered others which give the best fit values compatible with the spectral index of curvature perturbations, the tensor-to-scalar ratio, and the running of the spectral index within the allowed ranges suggested by the Planck and BICEP2 results.

description: Recently, we predicted theoretically that in cavities that support several longitudinal modes, strong coupling can occur in very different manners, depending on the system parameters. Distinct longitudinal cavity modes are either entangled with each other via the material or independently coupled to the exciton mode. Here we experimentally demonstrate the transition between those two regimes as the cavity thickness is gradually increased while maintaining fixed coupling strength. We study the properties of the system using reflection and emission spectroscopy and show that even though the coupling strength is constant, different behavior in the spectral response is observed along the coupling-decoupling transition. In addition, we find that in such multimode cavities pronounced upper-polariton emission is observed, in contrast to the usual case of a single-mode cavity. Furthermore, we address the ultrafast dynamics of the multimode cavities by pump-probe spectroscopic measurements and observe that the transient spectra significantly change through the transition.

description: Broadcasting problem is an important issue in the wireless networks, especially in dynamic wireless networks. In dynamic wireless networks the node density and mobility is high, due to several problems which arise during broadcasting. Two major problems faced are namely, Broadcast Storm Problem and Disconnected network problem. In a highly dense network, if information is being flooded in a loop, it could lead to broadcast storm. The broadcast storm may eventually crash the entire network and lead to loss of information. Mobility of the nodes may lead to the problem of Disconnected Network. If the two nodes sending and receiving information are mobile with different speeds, it could lead to a disconnection between them as soon as the receiver moves out of the communication range. In this paper, we are trying to solve both the problems based on our proposed algorithms.

This progress report describes the recent upsurge of interest in ARKs, the main difficulties posed by identifier management for the BnF and its community, and finally “ARK Summit 2018”, a major event in the construction of a francophone community of interest around ARK identifiers.
The Forward Modeling of the Inner Kinetochore in S. cerevisiae
Creators: name: Doshi, Ayush
Publisher: name: The University of North Carolina at Chapel Hill University Libraries

description: The kinetochore is a large protein complex that connects chromosomes to the mitotic spindle to ensure proper cell division. The kinetochore can be divided into two significant regions: the inner kinetochore, which includes proteins that interact with DNA; and the outer kinetochore, which includes microtubule-binding proteins. Due to the crucial nature of the kinetochore, it finds itself at the center of many studies aimed at characterizing the complex. However, similar to other forms of biological research, analysis and comparison of microscopy images present a significant investment of manpower and time. We propose a novel pipeline for image analysis tailored to the kinetochore that provides efficient feature extraction and insight into its 3D structure through the use of kernel classifiers and convolutional neural networks (CNN). The differentiation between inner and outer kinetochore structures along with the initial convolution of the inner kinetochores' 3D structure was used as a test case to display the usefulness of the pipeline. Its success attests to the usefulness of this pipeline as not only an effective method to analyze and understand the differences that occur structurally at the protein level, but also as an extremely time efficient one.

description: Scientists collect, generate, and analyze data in a variety of forms. Oftentimes, this leads to datasets that have been organized, rendered, and stored by and in different methods, software, and storage locations. Databases are one means by which to organize and retrieve data. The complexity of databases as digital objects presents practical challenges for archivists, data curators, and digital preservationists. In this paper we discuss a collaborative project to assess and develop strategies for preserving and creating access for a scientific database from the veterinary medicine domain that leverages archival, digital preservation, and data curation expertise and resources.

description: Here we study the stability of charge order in the kagome metal ScV6Sn6. Synchrotron x-ray diffraction measurements reveal high-temperature, short-range charge correlations at the wave vectors along q=(1/3,1/3,1/2) whose inter-layer correlation lengths diverge upon cooling. At the charge order transition, this divergence is interrupted and long-range order freezes in along q=(1/3,1/3,1/3), as previously reported, while disorder enables the charge correlations to persist at the q=(1/3,1/3,1/2) wave vector down to the lowest temperatures measured. Both short-range and long-range charge correlations seemingly arise from the same instability and both are rapidly quenched upon the introduction of larger Y ions onto the Sc sites. Our results validate the theoretical prediction of the primary lattice instability at q=(1/3,1/3,1/2), and we present a heuristic picture for viewing the frustration of charge order in this compound.

description: B2-ordered FeRh has been known to exhibit antiferromagnetic-ferromagnetic (AF-F) phase transitions in the vicinity of room temperature. Manipulation of the Néel order via AF-F phase transition and recent experimental observation of the anisotropic magnetoresistance in antiferromagnetic FeRh has proven that FeRh is a promising candidate for antiferromagnetic memory material. In this work, we demonstrate sequential write and read operations in antiferromagnetic memory resistors made of B2-orderd FeRh thin films by a magnetic field and electric current only. Our demonstration of writing and reading at ambient room temperature opens a realistic pathway towards operational antiferromagnetic memory devices.
Spectral Normalized-Cut Graph Partitioning with Fairness Constraints

description: Normalized-cut graph partitioning aims to divide the set of nodes in a graph into $k$ disjoint clusters to minimize the fraction of the total edges between any cluster and all other clusters. In this paper, we consider a fair variant of the partitioning problem wherein nodes are characterized by a categorical sensitive attribute (e.g., gender or race) indicating membership to different demographic groups. Our goal is to ensure that each group is approximately proportionally represented in each cluster while minimizing the normalized cut value. To resolve this problem, we propose a two-phase spectral algorithm called FNM. In the first phase, we add an augmented Lagrangian term based on our fairness criteria to the objective function for obtaining a fairer spectral node embedding. Then, in the second phase, we design a rounding scheme to produce $k$ clusters from the fair embedding that effectively trades off fairness and partition quality. Through comprehensive experiments on nine benchmark datasets, we demonstrate the superior performance of FNM compared with three baseline methods.

description: News, paradigm-shifting ideas, social movements, scientific discoveries and artistic creations have all been documented through audiovisual recordings. These recordings have, more than any other medium, created social memory, documented contemporary history and now form part of our Intangible Cultural Heritage. The only way to guarantee the permanence of content recorded on analogue audio-visual media is to digitize it (Bradley, 2006). For this reason, the race against time to digitize the largest number of recordings possible began around the end of the last century. The purpose is combating their technological obsolescence and material degradation as well as offering better access to these materials.
SPROUT: A moving mesh hydro code using a uniformly expanding Cartesian grid

description: We present the publicly available moving-mesh hydrodynamics code Sprout. Sprout solves the equations of ideal hydrodynamics on an expanding Cartesian mesh. The expanding mesh can follow fluid outflows for several orders of magnitude with very little numerical diffusion, thereby capturing shocks and fine structures accurately. Following the bulk flow accurately also allows for longer timesteps in general. This makes Sprout particularly suitable for studying expanding outflows such as supernova remnants and active galactic nuclei. Relative to other moving mesh codes, the simple mesh structure in Sprout is also convenient for implementing additional physics or algorithms. Many code tests are performed to test the accuracy and performance of the numerical scheme.

description: This paper examines some of the reasons behind the decisions of states on whether or not they chose to expand state Medicaid programs to include all individuals up to 138% of the federal poverty line following the passage of the Patient Protection and Affordable Care Act (ACA). What follows is a mixed methods study on the quantitative impact of both cost and ideology on Medicaid expansion decisions for states with Republican governors during the first expansion years as well as a more expansive qualitative analysis of the conditions surrounding two select cases.
Liquid relaxation: A new Parodi-like relation for nematic liquid crystals

description: We put forward a hydrodynamic theory of nematic liquid crystals that includes both anisotropic elasticity and dynamic relaxation. Liquid remodeling is encompassed through a continuous update of the shear-stress free configuration. The low-frequency limit of the dynamical theory reproduces the classical Ericksen-Leslie theory, but it predicts two independent identities between the six Leslie viscosity coefficients. One replicates Parodi's relation, while the other-which involves five Leslie viscosities in a nonlinear way-is new. We discuss its significance, and we test its validity against evidence from physical experiments, independent theoretical predictions, and molecular-dynamics simulations.

Strategies for tackling the computational cost of modeling reacting fluids and related problems
Creators: name: Niemeyer, Kyle E.
Publisher: name: Zenodo
Year: 2023
Subjects: reacting flows
combustion
ocean biogeochemistry

description: Talk given in the Department of Mechanical Engineering seminar series at the University of Connecticut. Accurate simulations of combustion and reacting fluid flows require complex, multi-step chemical kinetic models for describing the coupled chemical reactions. These models are often large and mathematically stiff, and contribute to the overall high computational expense of simulating practical phenomena relevant to energy, transportation, and aerospace applications. In this talk, I will introduce these issues, summarize the state-of-the-art in methods used to reduce computational costs, and describe some recent contributions from my group on adaptive preconditioning to accelerate implicit integration of stiff chemical kinetics. I will discuss how these developments, and others, are available in the open-source library Cantera. Finally, I will discuss how my group has extended strategies and methods from combustion modeling to other domains such as modeling of neutron transport and ocean biogeochemistry.
