description: The trend towards transitioning from monolithic applications to microservices has been widely embraced in modern distributed systems and applications. This shift has resulted in the creation of lightweight, fine-grained, and self-contained microservices. Multiple microservices can be linked together via calls and inter-dependencies to form complex functions. One of the challenges in managing microservices is provisioning the optimal amount of resources for microservices in the chain to ensure application performance while improving resource usage efficiency. This paper presents ChainsFormer, a framework that analyzes microservice inter-dependencies to identify critical chains and nodes, and provision resources based on reinforcement learning. To analyze chains, ChainsFormer utilizes light-weight machine learning techniques to address the dynamic nature of microservice chains and workloads. For resource provisioning, a reinforcement learning approach is used that combines vertical and horizontal scaling to determine the amount of allocated resources and the number of replicates. We evaluate the effectiveness of ChainsFormer using realistic applications and traces on a real testbed based on Kubernetes. Our experimental results demonstrate that ChainsFormer can reduce response time by up to 26% and improve processed requests per second by 8% compared with state-of-the-art techniques.

description: Spatio-temporal imaging of light propagation is very important in photonics because it provides the most direct tool available to study the interaction between light and its host environment. Sub-ps time resolution is needed to investigate the fine and complex structural features that characterize disordered and heterogeneous structures, which are responsible for a rich array of transport physics that have not yet been fully explored. A newly developed wide-field imaging system enables us to present a spatio-temporal study on light transport in various disordered media, revealing properties that could not be properly assessed using standard techniques. By extending our investigation to an almost transparent membrane, a configuration that has been difficult to characterize until now, we unveil the peculiar physics exhibited by such thin scattering systems with transport features that go beyond mainstream diffusion modeling, despite the occurrence of multiple scattering.

description: In this paper, by using scalar nonlinear parabolic equations, we construct supersolutions for a class of nonlinear parabolic systems including $$ \left\{\begin{array}{ll} \partial_t u=Δu+v^p,\qquad & x\inΩ,\,\,\,t>0,\\ \partial_t v=Δv+u^q, & x\inΩ,\,\,\,t>0,\\ u=v=0, & x\in\partialΩ,\,\,\,t>0,\\ (u(x,0), v(x,0))=(u_0(x),v_0(x)), & x\inΩ, \end{array} \right. $$ where $p\ge 0$, $q\ge 0$, $Ω$ is a (possibly unbounded) smooth domain in ${\bf R}^N$ and both $u_0$ and $v_0$ are nonnegative and locally integrable functions in $Ω$. The supersolutions enable us to obtain optimal sufficient conditions for the existence of the solutions and optimal lower estimates of blow-up rate of the solutions.

description: The interaction of a supermassive black hole with the matter of an accretion disk in the presence of a magnetic field is the key mechanism of energy release in active galactic nuclei. However, determining the physical parameters of this system, such as the spin and mass of the black hole, the shape and parameters of the rotation of the accretion disk, and the geometry of the magnetic field in the accretion disk is a complex and not completely solved problem. We have previously shown, based on our numerical models, that these estimates can be obtained from just three parameters: the black hole mass, bolometric luminosity, and optical polarization. In this paper, we estimate the accretion disk and black hole parameters for a sample of 14 type 1 Seyfert galaxies. Using the spectropolarimetric data obtained by us, we selected only those objects in which the polarization of optical radiation is generated mainly by the mechanism in the accretion disk. Despite the small statistics, our results for such a sample are consistent with our previous conclusions and show a discrepancy between the disk magnetic field parameters and the classical Shakura-Sunyaev disk model.

description: Within this study we attempted to create an objective assessment that would measure website quality to dispel the stereotype that information found on Wikipedia is inaccurate, ultimately to encourage clinicians to utilize the evidence based assessments (EBA) pages on Wikipedia. Over 900 participants were recruited from Amazon’s Mechanical Turk (MTurk) and were tasked to rate one webpage using the assessment and one webpage not using the assessment as either quality or not. An exploratory factor analysis revealed that our assessments measured four factors of website quality: style, maintenance/coverage, coverage, and authority. Correlational data supported style as one of the four factors, and suggests that style is an important factor to those rating the quality of a webpage. At the end of the study, over 70% of participants indicated that they would use the measure again, showing promise that this measure may make a difference in how websites such as Wikipedia are perceived and utilized.

description: Topology and geometry are essential to our understanding of modern physics, underlying many foundational concepts from high energy theories, quantum information, and condensed matter physics. In condensed matter systems, a wide range of phenomena stem from the geometry of the band eigenstates, which is encoded in the matrix-valued Wilson line for general multi-band systems. Using an ultracold gas of Rb atoms loaded in a honeycomb optical lattice, we realize strong-force dynamics in Bloch bands that are described by Wilson lines and observe an evolution in the band populations that directly reveals the band geometry. Our technique enables a full determination of band eigenstates, Berry curvature, and topological invariants, including single- and multi-band Chern and $Z_2$ numbers.

description: After the presence of high Bandwidth-Delay Product (high-BDP) networks, many researches have been conducted to prove either the existing TCP variants can achieve an excellent performance without wasting the bandwidth of these networks or not. In this paper, a comparative test-bed experiment on a set of high speed TCP variants has been conducted to show their differences in bandwidth utilization, loss ratio and TCP-Fairness. The involved TCP Variants in this experiment are: NewReno, STCP, HS-TCP, H-TCP and CUBIC. These TCP variants have been examined in both cases of single and parallel schemes. The core of this work is how to evaluate these TCP variants over a single bottleneck network using a new parallel scheme to fully utilize the bandwidth of this network, and to show the impact of accelerating these variants on bandwidth utilization, loss-ratio and fairness. The results of this work reveal that, first: the proposed parallel scheme strongly outperforms the single based TCP in terms of bandwidth utilization and fairness. Second: CUBIC achieved better performance than NewReno, STCP, H-TCP and HS-TCP in both cases of single and parallel schemes. Briefly, parallel TCP scheme increases the utilization of network resources, and it is relatively good in fairness.

description: Recommender systems often struggle to strike a balance between matching users' tastes and providing unexpected recommendations. When recommendations are too narrow and fail to cover the full range of users' preferences, the system is perceived as useless. Conversely, when the system suggests too many items that users don't like, it is considered impersonal or ineffective. To better understand user sentiment about the breadth of recommendations given by a movie recommender, we conducted interviews and surveys and found out that many users considered narrow recommendations to be useful, while a smaller number explicitly wanted greater breadth. Additionally, we designed and ran an online field experiment with a larger user group, evaluating two new interfaces designed to provide users with greater access to broader recommendations. We looked at user preferences and behavior for two groups of users: those with higher initial movie diversity and those with lower diversity. Among our findings, we discovered that different level of exploration control and users' subjective preferences on interfaces are more predictive of their satisfaction with the recommender.

Infection propagator approach to compute epidemic thresholds on temporal networks: impact of immunity and of limited temporal resolution

description: The epidemic threshold of a spreading process indicates the condition for the occurrence of the wide spreading regime, thus representing a predictor of the network vulnerability to the epidemic. Such threshold depends on the natural history of the disease and on the pattern of contacts of the network with its time variation. Based on the theoretical framework introduced in (Valdano et al. PRX 2015) for a susceptible-infectious-susceptible model, we formulate here an infection propagator approach to compute the epidemic threshold accounting for more realistic effects regarding a varying force of infection per contact, the presence of immunity, and a limited time resolution of the temporal network. We apply the approach to two temporal network models and an empirical dataset of school contacts. We find that permanent or temporary immunity do not affect the estimation of the epidemic threshold through the infection propagator approach. Comparisons with numerical results show the good agreement of the analytical predictions. Aggregating the temporal network rapidly deteriorates the predictions, except for slow diseases once the heterogeneity of the links is preserved. Weight-topology correlations are found to be the critical factor to be preserved to improve accuracy in the prediction.

Sickle Cell Anemia and Pain Crisis: Empowerment by Self Monitoring
Creators: name: Wehbie, Kassiane
Publisher: name: The University of North Carolina at Chapel Hill University Libraries

description: Sickle Cell Anemia is a debilitating genetic condition effecting nearly a million people in the United States. Sickle Cell Disease (SCD) causes dysfunctional, rigid, crescent shaped hemoglobin to aggregate within an individual’s cardiovasculature, causing an exacerbation of acute pain or consistent and intermittent chronic pain. Hydration status of red blood cells can contribute to factors effecting the sickling process and influence long term organ function. The purpose of this study is to describe the signs and symptoms adults with SCD associate with an emerging pain crisis, identify the self-care strategies adults with SCD use to mitigate a crisis; and explore individuals with Sickle Cell Disease interest in using wearable technology to monitor their health status. A cross-section of members from the online support community, OneSCDvoice (https://www.onescdvoice.com/), were recruited to complete an anonymous online questionnaire. The project received human subjects research approval from the University of North Carolina at Chapel Hill Institutional Review Board. Qualitative content analysis was used to code responses and identify themes. Results from this cross-sectional survey of adults with SCD indicated that participants link hydration status to the frequency, severity, and duration of sickle cell pain crisis. Participants identified a number of physiologic parameters a personal device should monitor and indicated a willingness to use a device for self-monitoring. Participants expressed enthusiasm for a devise to help monitor their disease and alert others that they are facing physiological decline and are in pain.

description: Interpreting regulatory documents or building codes into computer-processable formats is essential for the intelligent design and construction of buildings and infrastructures. Although automated rule interpretation (ARI) methods have been investigated for years, most of them highly depend on the early and manual filtering of interpretable clauses from a building code. While few of them considered machine interpretability, which represents the potential to be transformed into a computer-processable format, from both clause- and document-level. Therefore, this research aims to propose a novel approach to automatically evaluate and enhance the machine interpretability of single clause and building codes. First, a few categories are introduced to classify each clause in a building code considering the requirements for rule interpretation, and a dataset is developed for model training. Then, an efficient text classification model is developed based on a pretrained domain-specific language model and transfer learning techniques. Finally, a quantitative evaluation method is proposed to assess the overall interpretability of building codes. Experiments show that the proposed text classification algorithm outperforms the existing CNN- or RNN-based methods, improving the F1-score from 72.16% to 93.60%. It is also illustrated that the proposed classification method can enhance downstream ARI methods with an improvement of 4%. Furthermore, analyzing the results of more than 150 building codes in China showed that their average interpretability is 34.40%, which implies that it is still hard to fully transform the entire regulatory document into computer-processable formats. It is also argued that the interpretability of building codes should be further improved both from the human side and the machine side.

description: Information diffusion and disease spreading in communication-contact layered network are typically asymmetrically coupled with each other, in which how an individual being aware of disease responds to the disease can significantly affect the disease spreading. Many recent studies have demonstrated that human behavioral adoption is a complex and non-Markovian process, where the probability of adopting one behavior is dependent on the cumulative times of the received information and the social reinforcement effect of these cumulative information. We study the impact of such a non-Markovian vaccination adoption behavior on the epidemic dynamics and the control effects. We find that this complex adoption behavior caused from the communication layer can significantly increase the epidemic threshold and reduce the final infection rate. By defining the social cost as the sum of the cost of vaccination and the cost of treatment, we show that there exists an optimal social reinforcement effect or optimal information transmission rate allowing the minimal social cost. We also develop a mean field based theory to verify the correctness of the simulation results.

description: We investigate quantumness of spin-1 states, defined as the Hilbert-Schmidt distance to the convex hull of spin coherent states. We derive its analytic expression in the case of pure states as a function of the smallest eigenvalue of the Bloch matrix and give explicitly the closest classical state for an arbitrary pure state. Numerical evidence is provided that the exact formula for pure states provides an upper bound on the quantumness of mixed states. Due to the connection between quantumness and entanglement we obtain new insights into the geometry of symmetric entangled states.
Universal Formal Politics: Egalitarianism & Non-Relation in Alain Badiou
Creators: name: Beard, Ellery Nicholas
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2016

description: Egalitarian politics is based on the affirmation of the equality of all people. Unfortunately,
the precise meanings of this “equality” and this “all” often go unexplained. What exactly is
meant when all people are proclaimed as equals, not just linguistically, but in action and
organization? One obvious way to interpret the egalitarian statement is through the universal.
The two terms “all” and “equal” seem to straightforwardly imply the necessity of the universal.
While there may be some forms of left-wing politics that are not predicated on universality, those
forms cannot be egalitarian in the usual sense of the word.1 However, instead of arguing
explicitly against the opposing viewpoint, this paper will work by presenting a universalist
understanding of egalitarian politics, namely that of Alain Badiou.

In order to demonstrate the correspondence we develop a computational efficient way to calculate the ES of low-excitation of non-interacting systems. We observe and explain the presence of an unexpected shell structure in the excitation structure. The low-lying shell are robust and survive even for strong electron-electron interactions.

Caring Across Language Barriers: A Review of Literature Concerning Hispanic Women with Breast Cancer
Creators: name: Hood, Catherine
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2014

description: Hispanics are the fastest growing minority in the United States, and breast cancer is the most common type of cancer in Latina women (Lopez-Class,M. 2011). A review of literature and an interview with a bilingual nurse who regularly converses with Hispanic patients were done to look deeper into this multi-faceted problem. This review and interview were conducted because of the negative effects that cross-lingual and cross-cultural care has on patient satisfaction and outcomes. Additionally, multiple interventions were suggested in order to determine successful methods for overcoming linguistic and cultural differences that affect the care of Latina women with breast cancer. From the literature review, it was concluded that more research needs to be done. Future intervention studies can be conducted, including one in which interpreters are permanent members of the healthcare team. Furthermore, the means of evaluation should be focused on increasing patient satisfaction rates and decreasing medical errors.

description: Caching at small base stations (SBSs) has demonstrated significant benefits in alleviating the backhaul requirement in heterogeneous cellular networks (HetNets). While many existing works focus on what contents to cache at each SBS, an equally important problem is what contents to deliver so as to satisfy dynamic user demands given the cache status. In this paper, we study optimal content delivery in cache-enabled HetNets by taking into account the inherent multicast capability of wireless medium. We consider stochastic content multicast scheduling to jointly minimize the average network delay and power costs under a multiple access constraint. We establish a content-centric request queue model and formulate this stochastic optimization problem as an infinite horizon average cost Markov decision process (MDP). By using \emph{relative value iteration} and special properties of the request queue dynamics, we characterize some properties of the value function of the MDP. Based on these properties, we show that the optimal multicast scheduling policy is of threshold type. Then, we propose a structure-aware optimal algorithm to obtain the optimal policy. We also propose a low-complexity suboptimal policy, which possesses similar structural properties to the optimal policy, and develop a low-complexity algorithm to obtain this policy.

description: In this paper we investigate the chameleon effect in the different conformal frames of the Brans--Dicke theory. Given that, in the standard literature on the subject, the chameleon is described in the Einstein frame almost exclusively, here we pay special attention to the description of this effect in the Jordan and in the string frames. It is shown that, in general, terrestrial and solar system bounds on the mass of the BD scalar field, and bounds of cosmological origin, are difficult to reconcile at once through a single chameleon potential. We point out that, in a cosmological context, provided that the effective chameleon potential has a minimum within a region of constant density of matter, the Brans--Dicke theory transmutes into general relativity with a cosmological constant, in that region. This result, however, can be only locally valid. In cosmological settings de Sitter--general relativity is a global attractor of the Brans--Dicke theory only for the quadratic potential $V(ϕ)=M^2ϕ^2$, or for potentials that asymptote to $M^2ϕ^2$.

description: We have studied the variation in fine-structure splitting (FSS) under application of vertical electric field in a range of quantum dots grown by different methods. In each sample we confirm that this energy splitting changes linearly over the field range we can access. We conclude that this linear tuning is a general feature of self-assembled quantum dots, observed under different growth conditions, emission wavelengths and in different material systems. Statistical measurements of characteristic parameters such as emission energy, Stark shift and FSS tuning are presented which may provide a guide for future attempts to increase the yield of quantum dots that can be tuned to a minimal value of FSS with vertical electric field.

Bridgeland stability is in particular definedfor objects in the derived category D(X) = D b (Coh(X)) for a varietyX. We will show in Corollary 9.1 that, at least when X is an ellipticcurve, there is a heart of a bounded t-structure in D(X) which isequivalent to a category of vector bundles on a non-commutative torusrelated to X based on a description of this latter category by Polishchukand Schwarz 17. Under this equivalence, Bridgeland stable objectscorrespond to bundles with special connections.

We further offer an analytical theory of the energy spectra of steady-state quantum turbulence in the counterflow and pure superflow, based on algebraic approximation for the energy fluxes over scales. The resulting spectra are not of the classic Kolmogorov form, but strongly suppressed by the mutual friction, leading to the energy dissipation at all scales, enhanced by the counterflow-induced decoupling of the normal- and superfluid velocity fluctuations.

The Family Experience of Living with Cystic Fibrosis: A Case Study of Two Families
Creators: name: Prevatt, Lindy
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2016

description: The diagnosis of Cystic Fibrosis (CF) affects not only the well-being of the individual with the
condition, but also the well-being of other family members and the family as a whole. Our
understanding of the family experience of living with CF is limited. Much of the existing
research has focused on the experiences of individual family members, rather than the family as
a whole. Therefore, the purpose of this study was to explore the family experience of living with
a child that has CF. The guiding framework for the study was the Resiliency Model of Family
Stress, Adjustment and Adaptation. Semi-structured interviews were conducted with parents
from two families living with CF. Findings from this study illustrate how important it is for
nurses and other health care providers to recognize that no two families living with CF have the
exact same experience. Each family goes through their own unique journey. How a family
responds to the ongoing challenges associated with raising a child with CF will depend on
factors such as age of the child, number of children, work status of parents and family variables
like family demands, family appraisal, family resources, and family problem-solving and coping.
Nurses who understand this will provide a better quality of care, which will lead to greater
patient and family satisfaction, as well as increased job satisfaction for the nurse.

description: We present estimates for the size and the logarithmic slope of the disk temperature profile of the lensed quasar Q2237+0305, independent of the component velocities. These estimates are based on six epochs of multi-wavelength narrowband images from the Nordic Optical Telescope. For each pair of lensed images and each photometric band, we determine the microlensing amplitude and chromaticity using pre-existing mid-IR photometry to define the baseline for no microlensing magnification. A statistical comparison of the combined microlensing data (6 epochs $\times$ 5 narrow bands $\times$ 6 image pairs) with simulations based on microlensing magnification maps gives Bayesian estimates for the half-light radius of $R_{1/2}=8.5^{+7.5}_{-4.0}\sqrt{ \langle M \rangle/0.3\, M_\odot}$ light-days, and $p=0.95\pm0.33$ for the exponent of the logarithmic temperature profile $T\propto R^{ -1/p}$. This size estimate is in good agreement with most recent studies. Other works based on the study of single microlensing events predict smaller sizes, but could be statistically biased by focusing on high-magnification events.

description: Stunting affects one-in-five children globally and is associated with greater infectious morbidity, mortality and neurodevelopmental deficits. Recent evidence suggests that the early-life gut microbiome affects child growth through immune, metabolic and endocrine pathways. Using whole metagenomic sequencing, we map the assembly of the gut microbiome in 335 children from rural Zimbabwe from 1–18 months of age who were enrolled in the Sanitation, Hygiene, Infant Nutrition Efficacy Trial (SHINE; NCT01824940), a randomized trial of improved water, sanitation and hygiene (WASH) and infant and young child feeding (IYCF). Here, we show that the early-life gut microbiome undergoes programmed assembly that is unresponsive to the randomized interventions intended to improve linear growth. However, maternal HIV infection is associated with over-diversification and over-maturity of the early life gut microbiome in their uninfected children, in addition to reduced abundance of Bifidobacterium species. Using machine learning models (XGBoost), we show that taxonomic microbiome features are poorly predictive of child growth, however functional metagenomic features, particularly B-vitamin and nucleotide biosynthesis pathways, moderately predict both attained linear and ponderal growth and growth velocity. New approaches targeting the gut microbiome in early childhood may complement efforts to combat child undernutrition.

description: In the original pre-registration: https://osf.io/a65c7 it stated "We will be recruiting via email, and we will run the experiment with 100 participants." Data collection has just begun, no data have been looked at, but we now have access to the full participant pool (183 participants) so we wish to amend to this section. We will now stop data collection on Wed 8th April 2020 or when the student pool has been exhausted.
Women in The National Park Service: The Legacy of the Patriarchy

description: The United States Federal Government takes responsibility for protecting women when they are citizens, but when the government serves as an employer for the National Park Service (NPS), the government is not protecting female employees from mistreatment. Over the last century, the government has granted women the right to vote, pay equality, and civil rights, but women's experiences with the NPS did not merit the same efforts of inclusion. Women associated with the NPS faced issues of not having the right to work, job inequality, as well as sexual assault, discrimination, and harassment. The relationship between the protections given to all female citizens and the experiences of women in the NPS is a contradiction. The federal government created protections and systematic change, but the NPS, a federal agency, did not fully implement the change. This thesis analyzes the NPS to understand how the oppressions are the result of patriarchy. At the beginning of the 20th century, Park Ranger's wives aided in establishing national parks as a white male sphere. By the 1960s, more NPS employees were women, yet to become a Park Ranger, the NPS’s female employees had to overcome discriminatory job titles and uniforms allotted only for men. All of the NPS's history had sexual harassment, but in 2014, women at the Grand Canyon unified to demand an investigation into sexual harassment in the workplace.

description: Location-awareness is essential in various wireless applications. The capability of performing precise ranging is substantial in achieving high-accuracy localization. Due to the notorious ambiguity phenomenon, optimal ranging waveforms should be adaptive to the signal-to-noise ratio (SNR). In this letter, we propose to use the Ziv-Zakai bound (ZZB) as the ranging performance metric, as well as an associated waveform design algorithm having theoretical guarantee of achieving the optimal ZZB at a given SNR. Numerical results suggest that, in stark contrast to the well-known high-SNR design philosophy, the detection probability of the ranging signal becomes more important than the resolution in the low-SNR regime.

A Qualitative Meta-Synthesis of Family Experiences and Needs Regarding Health Care of Newly Diagnosed Children with Traumatic Brain Injury in the Acute Care Setting

description: Children with moderate to severe traumatic brain injury (TBI) are often represented by their parents, who play a vital role in supporting their child. Minimal research captures the parents’ experiences in the acute care setting, leading to a lack of evidence-based knowledge regarding the supportive needs they wish were available. This qualitative synthesis used the PRISMA guidelines to search for and assimilate peer-reviewed research on early parenting needs in the acute care setting following moderate to severe TBI. A total of 1188 studies were screened after searching three scientific databases (PubMed; CINAHL; PsycINFO). Inclusion criteria involved: (a) children < twenty-one years of age; (b) accidental moderate to severe TBI; (c) acute inpatient setting; (d) parent(s) views on support needs; (f) published within last eight years; and, (g) written in English. Eight articles met the inclusion criteria, and the following major themes were noted: emotional family burden, the child’s protection from physical and emotional harm, the desire for parents’ conservation of energy, the demand for frequent and thorough support and communication, and parents’ varying coping abilities. Findings emphasize that a lack of understanding of early parenting needs following moderate to severe TBI can lead to substantial communication and support barriers. These obstacles gravely interfere with the distributed knowledge and physical, cognitive, or emotional assistance provided to newly informed parents. We used this information to inform the provision of future support materials for families. Prospective research needs be conducted to reveal unidentified parent(s) needs of newly diagnosed children with TBI.

description: Quantum interference arising from superposition of states is a striking evidence of the validity of Quantum Mechanics, confirmed in many experiments and also exploited in applications. However, as for any scientific theory, Quantum Mechanics is valid within the limits in which it has been experimentally verified. In order to extend such limits, it is necessary to observe quantum interference in unexplored conditions such as moving terminals at large distance in Space. Here we experimentally demonstrate single photon interference at a ground station due to the coherent superposition of two temporal modes reflected by a rapidly moving satellite thousand kilometers away. The relative speed of the satellite induces a varying modulation in the interference pattern. The measurement of the satellite distance in real time by laser ranging allowed us to precisely predict the instantaneous value of the interference phase. We then observed the interference patterns with visibility up to $67\%$ with three different satellites and with path length up to 5000 km. Our results attest the viability of photon temporal modes for fundamental tests of Physics and Quantum Communications in Space.
