Modeling Epidemiological Spread on Contact Networks

Year: 2022

description: The rapid diffusion of a contagion amongst a population has detrimental impacts on both public health and economic stability. As individuals of a population come into contact, they can spread tangible materials, such as bacteria and viruses, through probabilistic diffusion of the resulting contact network. The probabilistic branching process of disease relies on the basic reproductive number, or the average contagiousness of the pathogen - a crude measure of the true impact of the virus. Multiple precautionary measures can be taken to reduce the reproductive number in the case of an epidemic. Stochastic agent-based modeling was used in this study to emulate and analyze the impacts of various public health measures on the coronavirus epidemic. These ABM simulations are carried out using the EpiModel package within R, implemented by the ERGM (Exponential Random Graph Model) package. This algorithm allows the network model to vary stochastically (randomly) over time. The following protocols implemented during the coronavirus epidemic were assessed: the mask mandate, the social distancing protocol, the reduction of initial infected population size (ex. travel restrictions), and national vaccination. The simulated examples within this study followed the susceptible-infectious-recovered/immune (SIR) compartmental model type. These simulations serve to model the spread of the coronavirus contagion through a connected network of 1,000 nodes and 4,000 edges over a span of 100 days. The findings of this study could point towards a tool for future researchers tasked with the difficult job of updating national safety standards and precautionary health measures to inhibit contagion spread.

description: We compute the next-to-leading order corrections of $O(α_s^2α^3)$ to the hadronic production of two oppositely charged leptons and two hard jets, $p p \to j j l^- l^+$, using Recola and Collier. We include electroweak and QCD corrections at the given order and all off-shell effects. We provide detailed predictions for the LHC operating at 13 TeV and obtain per-cent-level corrections for the total cross section. For differential distributions we find significant non-uniform distortions in high-energy tails at the level of several ten per cent due to electroweak Sudakov logarithms and deformations at the level of a few per cent for angular variables.

description: We show that the surface of an $s$-wave superconductor decorated with a two-dimensional lattice of magnetic impurities can exhibit chiral topological superconductivity. If impurities order ferromagnetically and the superconducting surface supports a sufficiently strong Rashba-type spin-orbit coupling, Shiba sub-gap states at impurity locations can hybridize into Bogoliubov bands with non-vanishing, sometimes large, Chern number $C$. This topological superconductor supports $C$ chiral Majorana edge modes. We construct phase diagrams for model two-dimensional superconductors, accessing the dilute and dense magnetic impurity limits analytically and the intermediate regime numerically. To address potential experimental systems, we identify stable configurations of ferromagnetic iron atoms on the Pb (111) surface and conclude that ferromagnetic adatoms on Pb surfaces can provide a versatile platform for two-dimensional topological superconductivity.

description: This study investigates the adjustment of large-scale localized buoyancy anomalies in mid-latitude regions and the nonlinear evolution of associated condensation patterns in both adiabatic and moist-convective environments. This investigation is carried out utilizing the two-layer idealized moist-convective Thermal Rotating Shallow Water (mcTRSW) model.Our investigation reveals that the presence of a circular positive potential temperature anomaly in the lower layer initiates an anticyclonic high pressure rotation, accompanied by a negative buoyancy anomaly in the upper layer, resulting in an anisotropic northeast-southwest tilted circulation of heat flux. The evolution of eddy heat fluxes, such as poleward heat flux, energy, and meridional elongation of the buoyancy field, heavily depends on the perturbation's strength, size, and vertical structure.
The heatwave initiates atmospheric instability, leading to precipitation systems such as rain bands and asymmetric latent heat release due to moist convection in a diabatic environment. This creates a comma cloud pattern in the upper troposphere and a comma-shaped buoyancy anomaly in the lower layer, accompanied by the emission of inertia gravity waves. The southern and eastern sectors of the buoyancy anomaly show an upward flux, generating a stronger cross-equatorial flow and inertia-gravity waves in a southward and eastward direction.
Furthermore, the simulations reveal a similar asymmetric pattern of total condensed liquid water content distribution, accompanied by the intensification of moist convection as rain bands. This intensification is more pronounced in barotropic structures than in baroclinic configurations with stagnant upper layers. This study highlights the importance of considering moist convection and its effects on atmospheric and oceanic flows in mid-latitude regions, as well as the role of buoyancy anomalies in generating heatwaves and precipitation patterns.

subject: AEROSPACE SYSTEMS

description: Aerospace systems are certainly part of those of which the complexity
has been dramatically and continuously increasing for several decades.
Not only are the vehicles increasingly more sophisticated but, since they are
interacting increasingly with other so-called “intelligent” systems, human or
machines, the overall system is even more complex.
Here, the word “complexity” is used in the common sense: it just means
“too big to fit in the head of a human being”. We undertake projects that
are always aimed beyond the previous ones and we now face challenges
that cannot be addressed without the aid of information technologies, which
extend human capabilities. We are at a point where the matter is not “simply”
to invent new systems, but to invent codes that will help to invent new complex
systems.
This fourth Aerospace Lab issue is dedicated to various techniques used
to address some of the most difficult issues in complex aerospace system
design. It is not focused on a sub-class of aspects; it is a gallery of articles
that will encompass the main issues to be addressed when considering
advanced aerospace systems. There are two groups of articles: those related
to embedded system concepts and those related to concept design aid.

description: We present measurements of internal proper motions at more than five hundred positions of NGC 2392, the Eskimo Nebula, based on images acquired with WFPC2 on board the Hubble Space Telescope at two epochs separated by 7.695 years. Comparison of the two observations shows clearly the expansion of the nebula. We measured the amplitude and direction of the motion of local structures in the nebula by determining their relative shift during that interval. In order to assess the potential uncertainties in the determination of proper motions in this object, and in general, the measurements were performed using two different methods, used previously in the literature. We compare the results from the two methods, and to perform the scientific analysis of the results we choose one, the cross-correlation method, as the more reliable. We go on to perform a "criss-cross" mapping analysis on the proper motion vectors which helps in the interpretation of the velocity pattern. Combining our results on the proper motions with radial velocity measurements obtained from high resolution spectroscopic observations, and employing an existing 3D model, we estimate the distance to the nebula as 1300 pc.

Street vendors, marketers, and politics in twentieth-century Puebla, Mexico
Creators: name: Mendiola García, Sandra C.
Publisher: name: No Publisher Supplied
Year: 2008

description: This dissertation examines the business and political organizing of street vendors and marketers in Puebla, one of Mexico's largest cities, during the twentieth-century. Paying special attention to female sellers, who constituted a large majority of the street vending population, this work explores the challenges that they faced when they tried to sell their merchandise in the city's public areas. Established store keepers, municipal inspectors, and the police constantly sought to remove street vendors from Puebla's downtown. Street vendors responded by organizing the Popular Union of Street Vendors (UPVA) in 1973. This militant and independent organization emerged during the height of left-wing student activism. The vendors' union played an active part in grass-roots politics in the aftermath of the 1968 uprising in Mexico City. The UPVA was organized in part by students, many of whom identified themselves as Maoists, and by female vendors. Women were tough and militant, willing to do practically anything to defend their rights to sell on the streets and care for their families. Several female vendors destroyed police cars and engaged in fights with authorities. They were also skilled negotiators and delivered speeches in front of hundreds of vendors. Street vendors were political actors who petitioned and organized to defend their economic rights and after the 1970s, participated in a larger movement that carried out struggles for better conditions outside the structure of the Institutional Revolutionary Party (PRI). From the mid-1970s to the early 1990s, the state was relentless in its effort to destroy the vendors' union. The UPVA remained a militant, independent organization despite state violence against its members.

The “Best-Kept Secret in America”: A Photographic Investigation of the Mississippi Delta’s Churches, Schools, and Casinos
Creators: name: Underwood, Greer
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2022

description: This thesis is a photographic essay that examines the histories and current conditions of three institutions in the Mississippi Delta: churches, schools, and casinos. Using original photography of each institution as well as academic research and analysis, this thesis explains how the Delta supports seemingly contradictory institutions within one region, and how each institution (or "pillar) depends upon the others to survive. Chapters one and two explore how the history of gambling paved the way to casino legalization in the Mississippi Delta and how casino revenue is crucial to Delta school success. Chapters three and four investigate how churches have acted as educational centers and social teachers throughout the civil rights movement and today, and how they contribute to equal education efforts in the Delta. Chapters five and six illustrate the unique relationship between Delta schools and casinos, and how the Delta's casino taxation system directly benefits schools. This work combines the power of photography with scholarly research to create a more comprehensive view of the Delta, as it is shaped by its churches, schools, and casinos.

Maternal Stress and Distress Tolerance as Predictors of Infant Sleep Quality
Creators: name: Grizzard, Sawyer
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2022

description: Stress is a part of life that is experienced by everyone that can impact many aspects of one’s day-to-day experience. This is especially true for new mothers, as raising an infant can be a particularly daunting task. This study examines whether high levels of maternal stress negatively impacts infant sleep quality, and whether this relationship is moderated by the mother’s ability to deal with stressful situations (distress tolerance). Using secondary data from the Brain and Early Experience Study at the University of North Carolina at Chapel Hill, I examined maternal stress levels, maternal distress tolerance levels, and infant sleep quality of 40 mother-infant dyads recruited from areas nearby the university. Maternal stress and distress tolerance were measured using four self-report questionnaires—one questionnaire from the prenatal time point and one questionnaire from the 6-month time point for each variable. Infant sleep was measured using actigraphy biofeedback technology, collected over a continuous 6-day, 7-night span during the 6-month time point. Despite my hypotheses, this study did not reveal any significant findings. This indicates that maternal stress and distress tolerance did not have a notable impact on infant sleep quality within this sample population. One marginally significant finding revealed that the covariate of infant gestational age at time of birth is negatively correlated with sleep efficiency under some conditions—the implications of which are considered and discussed within the paper. Study limitations and directions for future research are also discussed.

description: We study the mean square of sums of the $k$th divisor function $d_k(n)$ over short intervals and arithmetic progressions for the rational function field over a finite field of $q$ elements. In the limit as $q\rightarrow\infty$ we establish a relationship with a matrix integral over the unitary group. Evaluating this integral enables us to compute the mean square of the sums of $d_k(n)$ in terms of a lattice point count. This lattice point count can in turn be calculated in terms of certain polynomials, which we analyse. Our results suggest general conjectures for the corresponding classical problems over the integers, which agree with the few cases where the answer is known.

Provable Algorithms for Reinforcement Learning: Efficiency, Scalability, and Robustness

description: Reinforcement learning (RL), which strives to learn desirable sequential decisions based on trial-and-error interactions with an unknown environment, has achieved remarkable success recently in a variety of domains including games and large language model alignment. In the face of unknown environments with unprecedentedly large dimensionality, making the best use of available samples inevitably lies at the core of RL, especially in ubiquitous sample-starved scenarios such as clinical trials and autonomous driving. To understand and tackle the challenges of sample efficiency, substantial progress has been made recently by developing a finite-sample theoretical framework to analyze the algorithms of interest and design provably optimal algorithms in terms of sample efficiency. Nevertheless, existing results still fall short with regards to the statistical understanding and algorithmic optimality in a wide range of RL settings. Moreover, motivated by countless scenarios with large dimensionality or sim-to-real gaps, sample efficiency needs to be considered along with scalability and robustness — two equally important principles in RL. This thesis breaks down the sample barriers of various RL formulations, taking additional scalability and robustness into account. Specifically, for online RL that allows for adaptive interactions with the environment, this thesis provides the first provable regret-optimal model-free RL algorithm with a small burn-in cost — an initial sampling burden needed for the algorithm to exhibit the desired performance — while maintaining its memory efficiency for scalability. For offline RL that only has access to historical datasets, this thesis proposes the first provable near-optimal model-free offline RL algorithm without the need of performing model estimation, and settles the sample complexity by establishing the minimax optimality of model-based offline RL algorithms without burn-in cost. Finally, for a robust variant of standard RL — distributionally robust RL, this thesis uncovers a surprising fact that promoting additional distributional robustness in the learned policy is neither necessarily harder nor easier than standard RL in terms of sample requirements, which depends heavily on the prescribed uncertainty set. This thesis closes by providing the first provable near-optimal algorithm for offline robust RL that can learn under simultaneous model uncertainty and limited historical datasets.

description: This thesis looks at the depictions of ethnic Koreans in German news media. Using postcolonial theory, the media analysis centers around racism and the perpetuation of the Model Minority Myth as well as the portrayal of the identity and culture of the Korean diaspora in the media. This thesis shows how German news media has perpetuated racism, stereotypes, and the history erasure of ethnic Korean people in Germany. These prejudices have in turn affected the everyday lives of the Korean diaspora.

We show that for a Fano complete intersection in Grassmannians the result of the above construction is birational to a complex torus. In other words, the complete intersections under consideration have very weak Landau--Ginzburg models.

description: A obra “Retrato de Duque de Caxias”, de Oswaldo Teixeira (1905-1974), é um óleo sobre tela que faz parte do acervo da Presidência da República do Brasil. Como o título sugere, a pintura retrata Luís Alves de Lima e Silva (1803-1880), patrono do Exército Brasileiro, conhecido pelo seu título Duque de Caxias. Em 08 de janeiro de 2023, ela foi alvo de vandalismo causado durante os atos antidemocráticos na invasão ao Palácio do Planalto quando recebeu uma marcação com um tipo de caneta azul no local onde está representado o bigode grisalho do Duque. Um ano após o ocorrido, essa obra, juntamente com outras dezenove, foi incluída no projeto de restauração realizado através da parceria estabelecida entre a Universidade Federal de Pelotas (Ufpel), o Instituto do Patrimônio Histórico e Artístico Nacional (Iphan) e a Presidência da República, representada pelo Departamento Curatorial dos Palácios Presidenciais (DCPP). O objetivo do projeto é restaurar essas obras devolvendo sua integridade física e estética, recuperando seu estado anterior ao vandalismo. O processo de restauração envolveu a desmontagem da obra de sua moldura e bastidor para a higienização e consolidação do suporte e da camada pictórica, estiramento no bastidor, limpeza química, nivelamento de lacunas, reintegração pictórica, aplicação de camada de proteção e tratamento na moldura. Como resultado foi possível devolver a obra ao seu estado ideal, cumprindo os objetivos do projeto. As etapas seguintes serão a realização da documentação final registrando detalhadamente todos os procedimentos realizados.

description: Self-assembled hierarchical solid surfaces are very interesting for wetting phenomena, as observed in a variety of natural and artificial surfaces. Here, we report single-walled (SWCNT) and multi-walled carbon nanotube (MWCNT) thin films realized by a simple, rapid, reproducible, and inexpensive filtration process from an aqueous dispersion, that was deposited at room temperature by a dry-transfer printing method on glass. Furthermore, the investigation of carbon nanotube films through scanning electron microscopy (SEM) reveals the multi-scale hierarchical morphology of the self-assembled carbon nanotube random networks. Moreover, contact angle measurements show that hierarchical SWCNT/MWCNT composite surfaces exhibit a higher hydrophobicity (contact angles of up to 137°) than bare SWCNT (110°) and MWCNT (97°) coatings, thereby confirming the enhancement produced by the surface hierarchical morphology.

description: Three train tracks run through Teaneck, NJ, a suburban city, unimpeded by road crossings; the tracks are as close as 7 meters to residential properties. In 2000, trains began idling in Teaneck for extended periods of time (up to 54 hours), exposing residents to persistent, elevated sound levels, as well as diesel emissions, and generating complaints. The goals of this study were to characterize the time-activity patterns of passby and idling trains; idling locations; and the sound emission levels of passbys, idling locomotives, and train horns over a one-year period. From October 2006 through November 2007, source sound levels were measured continuously with a Norsonic 121 sound-level meter and WAV files of actual sounds were recorded during train events. Concurrently, research staff visually noted train activities 24 hours/day, every third day, for three consecutive weeks each season, including train direction, track, idle location, locomotive-to-meter distance (idles), and other identifying information. Specific source characterization measurements of individual locomotives were made at measured distances with a hand-held Quest 2900 sound-level meter. Over this time period: ~1.2 trains passed per hour (1.1 daytime; 1.4 nighttime, 10 p.m.-7 a.m.); average passby duration was 2.8 minutes; and passbys were most frequent during the midnight hour. Trains tended to travel southbound during the day and northbound at night, resulting in horn blowing behind homes, while people slept, as the trains approached a grade crossing on Teaneck’s northern boundary. Idles averaged 87.2 minutes in duration, with the longest lasting ~36 hours. Idle events occurred equally in southern and northern Teaneck, but average idle durations in southern Teaneck were 2-3 times longer than all other locations. Train(s) idled in Teaneck for a total of ~10.7 hours/day, or 44.6% of the time. Average sound levels at 30.5 meters (100 feet) were: 78.1 dBA (peak: 84.9 dBA) for passby trains; 65.0 dBA (68.5 dBA) for single, idling locomotives; and 104.3 dBA (109.0 dBA) for train horns. Ambient sound-level measurements in neighborhoods had an Ldn of ~50 dBA. Sound emissions from train activity produced moderate-to-severe noise impacts in areas within 152 meters (500 feet) of the railway, especially during non-summer nights.
The prediction and discovery of novel small open reading frame encoded polypeptides in Enterococcus faecalis

description: Recent multi-omic efforts have facilitated the discovery of unannotated small open reading frame encoded polypeptides (SEPs). SEPs are small proteins (< 50 amino acids in length) representing an underexplored class of biomolecules due to the lack of genome prediction software and challenges in identification. However, increasing evidence demonstrates that SEPs play critical roles in cellular processes and serve diverse microbiological functions. Some known SEPs exhibit functions such as promoting pathogenesis, stabilizing protein complexes, and containing antimicrobial properties. Enterococcus faecalis is a ubiquitous member of healthy human gut microbiota with duality as a probiotic commensal as well as an opportunistic pathogen. The absence of pathogen-specific genes or pathogen-specific features suggests that E. faecalis’s virulence is determined by the host-microbe interaction. To this end, we hypothesize that the expression of various SEPs associate with E. faecalis’ transition from a commensal to pathogenic in changing environments. Herein, a six-frame genome translation and smORFinder were used for creating a predicted E. faecalis SEP database. A novel SEP was discovery through a parallel top-down and bottom-up proteomics approach with mass spectrometry.
Connectivity between Emotion Regulation Brain Regions in Children with ADHD

description: In this study we sought to understand how within and between connectivity of certain groups of brain regions related to emotion dysregulation and how these connections differed in children with attention deficit hyperactivity disorder (ADHD) as compared to those who are typically developing (TD). Functional connectivity was measured using fMRI data and emotion dysregulation was measured through questionnaires filled out by parents. Linear regressions comparing both within and between group connectivity found no significant relationship between connectivity and emotion dysregulation. T-tests found no significant difference in connectivity between samples. However, prior to multiple analysis corrections, the ADHD sample had significantly higher connectivity between the amygdala and the ventral striatum, and the TD sample had significantly higher connectivity between the orbitofrontal cortex and the middle temporal gyrus and angular gyrus. These findings suggest possible differences in connectivity between emotional processing regions and emotional regulation regions when comparing those with and without ADHD, warranting more research to develop a better understanding of these differences and how they may relate to emotion dysregulation.

description: We study the adsorption and ring-opening of lactide on the naturally chiral metal surface Pt(321)$^S$. Lactide is a precursor for polylactic acid ring-opening polymerization and Pt is a well known catalyst surface. We study here the energetics of the ring-opening of lactide on a surface that has a high density of kink atoms. These sites are expected to be present on a realistic Pt surface and show enhanced catalytic activity. The use of a naturally chiral surface also enables us to study potential chiral selectivity effects of the reaction at the same time. Using Density Functional Theory (DFT) with a functional that includes the van der Waals forces in a first-principles manner, we find modest adsorption energies of around 1.4 eV for the pristine molecule and different ring-opened states. The energy barrier to be overcome in the ring-opening reaction is found to be very small at 0.32 eV and 0.30 eV for LL- and its chiral partner DD-lactide, respectively. These energies are much smaller than the activation energy for a dehydrogenation reaction of 0.78 eV. Our results thus indicate that (a) ring-opening reactions of lactide on Pt(321) can be expected already at very low temperatures and Pt might be a very effective catalyst for this reaction; (b) the ring-opening reaction rate shows noticeable enantioselectivity.

description: Due to urbanization, there has been a rapid expansion in the developing cities, due to which there has been a large increase in the impervious surface area through the expansion of parking lots, roadways and other built up structures which resulted in altered natural water flows, reduced groundwater recharge, increased surface temperatures, and also have impacted water quality. Green infrastructure mimics natural systems to lessen these impacts and have a numerous environmental, social and economic benefits. The main objective of this thesis is to develop strategies for implementing green infrastructure on a municipal scale. Three different potentials were considered for analysis. First potential focuses on implementing green infrastructure for the entire municipality whereas the second potential focuses on implementing green infrastructure only in the area under 100-year flood zone. As a part of assessing the third potential a GIS suitability model is developed by integrating three key factors of green infrastructure suitability: soil type, land cover and tree canopy, and for the third potential green infrastructure techniques are implemented only in the highly suitable area from the model. Cost analysis is done for these three potentials for implementing different green infrastructure techniques like green roof, rain garden, bio swales, vegetation filter strips, planter box, permeable parking, permeable sidewalk and permeable driveway. Cost analysis is performed for a 50-year time horizon using a software package. Also the maximum surface run-off that will be captured by the used green infrastructure techniques is calculated for all the three potentials using the software package. This analysis hopes to provide technical support for practitioners and community planners for implementation of green infrastructure at municipal scale.
