description: We study the behaviour of a symmetric exclusion process in the presence of non-Markovian stochastic resetting, where the configuration of the system is reset to a step-like profile at power-law waiting times with an exponent $α$. We find that the power-law resetting leads to a rich behaviour for the currents, as well as density profile. We show that, for any finite system, for $α<1$, the density profile eventually becomes uniform while for $α>1$, an eventual non-trivial stationary profile is reached. We also find that, in the limit of thermodynamic system size, at late times, the average diffusive current grows $\sim t^θ$ with $θ= 1/2$ for $α\le 1/2$, $θ= α$ for $1/2 < α\le 1$ and $θ=1$ for $α> 1$. We also analytically characterize the distribution of the diffusive current in the short-time regime using a trajectory-based perturbative approach. Using numerical simulations, we show that in the long-time regime, the diffusive current distribution follows a scaling form with an $α-$dependent scaling function. We also characterise the behaviour of the total current using renewal approach. We find that the average total current also grows algebraically $\sim t^ϕ$ where $ϕ= 1/2$ for $α\le 1$, $ϕ=3/2-α$ for $1 < α\le 3/2$, while for $α> 3/2$ the average total current reaches a stationary value, which we compute exactly. The variance of the total current also shows an algebraic growth with an exponent $Δ=1$ for $α\le 1$, and $Δ=2-α$ for $1 < α\le 2$, whereas it approaches a constant value for $α>2$. The total current distribution remains non-stationary for $α<1$, while, for $α>1$, it reaches a non-trivial and strongly non-Gaussian stationary distribution, which we also compute using the renewal approach.

The effectiveness of packing post incision and drainage among patients with skin abscesses in improved wound healing and reduced recurrence
Creators: name: Ford, Natalie

Year: 2017

description: Introduction: A skin abscess is an accumulation of pus beneath the skin and is among one of the most
common skin and soft tissue infections. Skin abscesses can occur in anyone including healthy
patients with no comorbidities. They can occur anywhere on the body, but are common in
friction-prone areas such as the buttocks, breast and groin. Patients present with tender
nodules with fluctuance, induration, and erythema. Definitive management for abscesses is
incision and drainage, with or without the placement of packing material.
The purpose of this article is to review the necessity of wound packing in the healing
outcomes and recurrence of infection after incision and drainage compared to no packing in
patients with a skin abscess. Evaluation of this topic has the potential to improve patient care
while reducing overall health care costs.
First, we will discuss the epidemiology, pathophysiology, diagnosis and management
options for skin abscess. Then, we will review the most recent literature to answer the
aforementioned question at hand.

description: We investigate the dynamical stability of the holographic system with two order parameters, which exhibits competition and coexistence of condensations. In the linear regime, we have developed the gauge dependent formalism to calculate the quasi-normal modes by gauge fixing, which turns out be considerably convenient. Furthermore, by giving different Gaussian wave packets as perturbations at the initial time, we numerically evolve the full nonlinear system until it arrives at the final equilibrium state. Our results show that the dynamical stability is consistent with the thermodynamical stability. Interestingly, the dynamical evolution, as well as the quasi-normal modes, shows that the relaxation time of this model is generically much longer than the simplest holographic system. We also find that the late time behavior can be well captured by the lowest lying quasi-normal modes except for the non-vanishing order towards the single ordered phase. To our knowledge, this exception is the first counter example to the general belief that the late time behavior towards a final stable state can be captured by the lowest lying quasi-normal modes. In particular, a double relation is found for this exception in certain cases.

In the far region, the spacetime approaches a five-dimensional Kasner universe with a expanding three-dimensional space and a shrinking extra dimension. Near the event horizon, the spacetime is approximately static and has a smooth event horizon. We also study the motion of test particles around the black string and show the existence of quasi-circular orbits. Finally, we briefly discuss the stability of this spacetime.

Prescribing Prep: A Guide to Oral HIV Prophylaxis

Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2017

description: Background: Currently, the war on Human Immunodeficiency Virus (HIV) focuses on prevention in the forms of condoms, abstinence, and status awareness. However, once an individual is diagnosed with HIV, the focus on prevention switches to treatment. A patient’s knowledge of personal HIV status, use of barrier methods during sexual activity, and adherence to Highly Active Antiretroviral Therapy (HAART) can help prevent new infections in the HIV negative population. An additional method to limit seroconversion and subsequent HIV infection from exposure is pre-exposure prophylaxis (PrEP). Tenofovir disoproxil fumarate (TDF) is a commonly utilized PrEP agent; it is generally considered safe, however it is associated with renal, endocrine and bone toxicity. This paper aims to address the risks of PrEP administration in HIV negative patients.

description: Continual learning with an increasing number of classes is a challenging task. The difficulty rises when each example is presented exactly once, which requires the model to learn online. Recent methods with classic parameter optimization procedures have been shown to struggle in such setups or have limitations like non-differentiable components or memory buffers. For this reason, we present the fully differentiable ensemble method that allows us to efficiently train an ensemble of neural networks in the end-to-end regime. The proposed technique achieves SOTA results without a memory buffer and clearly outperforms the reference methods. The conducted experiments have also shown a significant increase in the performance for small ensembles, which demonstrates the capability of obtaining relatively high classification accuracy with a reduced number of classifiers.

description: We revisit the phenomenological predictions of the Universal Texture Zero (UTZ) model of flavour originally presented in arXiv:1710.01741, and update them in light of both improved experimental constraints and numerical analysis techniques. In particular, we have developed an in-house Markov Chain Monte Carlo (MCMC) algorithm to exhaustively explore the UTZ's viable parameter space, considering both leading- and next-to-leading contributions in the model's effective operator product expansion. We also extract -- for the first time -- reliable UTZ predictions for the (poorly constrained) leptonic CP-violating phases, and ratio observables that characterize neutrino masses probed by (e.g.) oscillation, $β$-decay, and cosmological processes. We therefore dramatically improve on the proof-in-principle phenomenological analysis originally presented in arXiv:1710.01741, and ultimately show that the UTZ remains a minimal, viable, and appealing theory of flavour. Our results also further demonstrate the potential of robustly examining multi-parameter flavour models with MCMC routines.

Incorporation of Medication-Assisted Treatment with Buprenorphine into Primary Care Practice

description: In 2015, over 3.8 million people reported misusing prescription pain
                    medication within the last month and over 5.1 million people in the United
                    States admitted to using heroin at some point in their lives. Despite the
                    widespread prevalence of opioid abuse, evidence-based treatments, such as
                    medication-assisted treatment (MAT), have yet to be made widely available and
                    easily accessible to patients. This program plan was designed to recommend
                    strategies to effectively incorporate MAT into the primary care setting.
                    Interviews were compiled from key informants at primary care clinics with
                    successful MAT programs in the Chapel Hill, North Carolina and surrounding area
                    in order to develop a model of practice transformation that could be applied to
                    a primary care clinic that does not currently provide MAT services. Ultimately,
                    the key factors to consider when implementing MAT in the primary care setting
                    include: provider buy-in, the availability of behavioral support staff, and
                    support of key administrative and support staff.
Phase transitions in the majority-vote model with two types of noises

description: In this work we study the majority-vote model with the presence of two distinc noises. The first one is the usual noise $q$, that represents the probability that a given agent follows the minority opinion of his/her social contacts. On the other hand, we consider the independent behavior, such that an agent can choose his/her own opinion $+1$ or $-1$ with equal probability, independent of the group's norm. We study the impact of the presence of such two kinds of stochastic driving in the phase transitions of the model, considering the mean field and the square lattice cases. Our results suggest that the model undergoes a nonequilibrium order-disorder phase transition even in the absence of the noise $q$, due to the independent behavior, but this transition may be suppressed. In addition, for both topologies analyzed, we verified that the transition is in the same universality class of the equilibrium Ising model, i.e., the critical exponents are not affected by the presence of the second noise, associated with independence.

description: Brain-inspired neuromorphic computing is a promising path towards next generation analogue computers that are fundamentally different compared to the conventional von Neumann architecture. One model for neuromorphic computing that can mimic the human brain behavior are spiking neural networks (SNNs), of which one of the most successful is the leaky integrate-and-fire (LIF) model. Since conventional complementary metal-oxide-semiconductor (CMOS) devices are not meant for modelling neural networks and are energy inefficient in network applications, recently the focus shifted towards spintronic-based neural networks. In this work, using the advantage of antiferromagnetic insulators, we propose a non-volatile magnonic neuron that could be the building block of a LIF spiking neuronal network. In our proposal, an antiferromagnetic domain wall in the presence of a magnetic anisotropy gradient mimics a biological neuron with leaky, integrating, and firing properties. This single neuron is controlled by polarized antiferromagnetic magnons, activated by either a magnetic field pulse or a spin transfer torque mechanism, and has properties similar to biological neurons, namely latency, refraction, bursting and inhibition. We argue that this proposed single neuron, based on antiferromagnetic domain walls, is faster and has more functionalities compared to previously proposed neurons based on ferromagnetic systems.

description: We study new $1/24$ BPS circular Wilson loops in ABJ(M) theory, which are defined in terms of several parameters that continuously interpolate between previously known $1/6$ BPS loops (both bosonic and fermionic) and $1/2$ BPS fermionic loops. We compute the expectation value of these operators up to second order in perturbation theory using a one-dimensional effective field theory approach. Within dimensional regularization, we find non-trivial $β$-functions for the parameters, which are marginally relevant deformations triggering RG flows from a UV fixed point represented by the $1/6$ BPS bosonic loop to an IR fixed point represented by a $1/2$ BPS fermionic loop. Generically, along all flows at least one supercharge of the theory is preserved, so that we refer to them as enriched RG flows. In particular, fixed points are connected through $1/6$ BPS fermionic operators. This holds at framing zero, which is a consequence of the regularization scheme employed. We also establish a g-theorem, relating the expectation values of the Wilson loops corresponding to the UV and IR fixed points of the flow, and discuss the one-dimensional defect SCFT living on the Wilson loop contour.

The Association of Single Sport Specialization and Overuse Injury in Youth Athletics
Creators: name: Taylor, Daniel
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2017

description: BACKGROUND:
Youth sports in today’s society has come to represent a microcosm of the highly visible
and overtly publicized professional world of sports.  Children and adolescents are inundated by
an unprecedented and ubiquitous sociocultural saturation not experienced by previous
generations; from the most recent current global news events trending on our Twitter feeds to
the latest player to sign a $200 million professional sports contract.  While the former is
newsworthy, the latter is what often catches the eyes of not only kids, but their parents,
coaches, and other individuals that are involved with different athletic programs at the youth
level.  There is an evolving perception that if kids are put into the right situations at an early
age, identifying a niche and “specializing” in a sport, they can advance and develop a skill set
that will allow them to obtain higher social status, possibly receive college athletic scholarships,
and even become professional athletes with high earning potential.  This perception is not a
geographically isolated concept.  In China, there are over 3000 government-affiliated sportsbased
schools, of which there are approximately 100 boarding schools dedicated to allowing
children ages 5-16 years old to work and develop sport-specific athletic skills in hopes of being
selected to train at Olympic training facilities.  The amount of pressure being placed on young
athletes is certainly high, and has a large impact physically and mentally.

description: Transformer-based pre-trained models have emerged as the predominant solution for natural language processing (NLP). Fine-tuning such pre-trained models for downstream tasks often requires a considerable amount of labeled private data. In practice, private data is often distributed across heterogeneous mobile devices and may be prohibited from being uploaded. Moreover, well-curated labeled data is often scarce, presenting an additional challenge. To address these challenges, we first introduce a data generator for federated few-shot learning tasks, which encompasses the quantity and skewness of scarce labeled data in a realistic setting. Subsequently, we propose AUG-FedPrompt, a prompt-based federated learning system that exploits abundant unlabeled data for data augmentation. Our experiments indicate that AUG-FedPrompt can perform on par with full-set fine-tuning with a limited amount of labeled data. However, such competitive performance comes at a significant system cost.

description: The aim of this thesis is to design and implement a Framework for collecting, managing and processing movement data. Initially, a brief description of the problem and the solution we offer. Then we analyze the cross-platform tools we decided to implement a test application to investigate each tool's capabilities and user experience, their advantages and disadvantages, and the reasons we rejected some of them. After, we examine the architecture of the tool in which the application was developed, its structural parts such as the manner it creates the interface, the integration of the code in two different operating systems and the tools it offers to create the application. Next, we present the features of the application which works on mobile devices that have Android and IOS operating systems. By using the application the user will be able to log into the system and share the data of their movements. The data will be stored in a central system which will process and manage them. Subsequently, we thoroughly study the development of all the functions of the application, the various screens, the user interface that each user sees and the various problems that arose and how to solve them. Later, we analyze how the application connects to the database system we created and selected after research and how the data is sent by creating a custom solution. Finally, we report the conclusions that emerged from the development of the entire framework that we created from scratch, the problems that arose during the creation of the Framework and finally the goals that we have set for the further development of the solution that we created.

description: Finite-above inverse monoids are a common generalization of finite inverse monoids and Margolis--Meakin expansions of groups. Given a finite-above $E$-unitary inverse monoid $M$ and a group variety $\mathit{U}$, we find a condition for $M$ and $\mathit{U}$, involving a construction of descending chains of graphs, which is equivalent to $M$ having an $F$-inverse cover via $\mathit{U}$. In the special case where $\mathit{U}=\mathit{Ab}$, the variety of Abelian groups, we apply this condition to get a simple sufficient condition for $M$ to have no $F$-inverse cover via $\mathit{Ab}$, formulated by means of the natural parial order and the least group congruence of $M$.

description: The ability to execute high-fidelity operations is crucial to scaling up quantum devices to large numbers of qubits. However, signal distortions originating from non-linear components in the control lines can limit the performance of single-qubit gates. In this work, we use a measurement based on error amplification to characterize and correct the small single-qubit rotation errors originating from the non-linear scaling of the qubit drive rate with the amplitude of the programmed pulse. With our hardware, and for a 15-ns pulse, the rotation angles deviate by up to several degrees from a linear model. Using purity benchmarking, we find that control errors reach $2\times 10^{-4}$, which accounts for half of the total gate error. Using cross-entropy benchmarking, we demonstrate arbitrary-angle single-qubit gates with coherence-limited errors of $2\times 10^{-4}$ and leakage below $6\times 10^{-5}$. While the exact magnitude of these errors is specific to our setup, the presented method is applicable to any source of non-linearity. Our work shows that the non-linearity of qubit drive line components imposes a limit on the fidelity of single-qubit gates, independent of improvements in coherence times, circuit design, or leakage mitigation when not corrected for.

Human Immunodeficiency Virus and Latency Reversing Agents A Path to Cure?
Creators: name: Shah, Riti
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2017

description: Background:
Human immunodeficiency virus (HIV), as its namesake implies, is a virus that
ultimately causes a deficient immune system that can lead to Acquired Immune
Deficiency Syndrome (AIDS). Since the discovery of this cytopathic virus in 1983,
there have been many scientific advances in regards to its identification and
treatment. In 1985, a diagnostic serologic test was developed, and shortly after, in
1987, antiretroviral drugs were introduced. Since these breakthroughs, further
improvements in diagnosis and management have been made for individuals
afflicted with HIV, including the revolutionary development of combination
antiretroviral therapy (cART) in 1996. Despite these advances, in 2014, there were
an estimated 1.2 million people in the United States living with HIV, and an
estimated 44,073 new HIV diagnoses. Treatment with cART does not completely
eradicate HIV, and interruption of therapy leads to prompt increase in viral load,
therefore lifelong therapy is required for viral suppression. This viral rebound upon
therapy cessation indicates the presence of an anatomical reserve where HIV
continues to replicate, better known as latent reservoirs. These reservoirs are the
main hindrance to complete viral remission, or cure. The purpose of this paper is to
explore this problem and address the clinical question: Do latency-reversing agents
(LRAs) eradicate human immunodeficiency virus (HIV) in patients with latent HIV
on highly active antiretroviral therapy (HAART)? This paper will explore relevant
epidemiology, pathophysiology, and innovative research on this topic and then
address the question of LRAs’ role in the eradication of HIV.

description: We report the discovery of spiral galaxies that are as optically luminous as elliptical brightest cluster galaxies, with r-band monochromatic luminosity L_r=8-14L* (4.3-7.5E44 erg/s). These super spiral galaxies are also giant and massive, with diameter D=57-134 kpc and stellar mass M_stars=0.3-3.4E11 M_sun. We find 53 super spirals out of a complete sample of 1616 SDSS galaxies with redshift z<0.3 and L_r>8L*. The closest example is found at z=0.089. We use existing photometry to estimate their stellar masses and star formation rates (SFRs). The SDSS and WISE colors are consistent with normal star-forming spirals on the blue sequence. However, the extreme masses and rapid SFRs of 5-65 M_sun/yr place super spirals in a sparsely populated region of parameter space, above the star-forming main sequence of disk galaxies. Super spirals occupy a diverse range of environments, from isolation to cluster centers. We find four super spiral galaxy systems that are late-stage major mergers--a possible clue to their formation. We suggest that super spirals are a remnant population of unquenched, massive disk galaxies. They may eventually become massive lenticular galaxies after they are cut off from their gas supply and their disks fade.

description: Στη σημερινή κοινωνία το να χρησιμοποιεί κάποιος εφαρμογές για καθημερινές δραστηριότητες είναι τόσο φυσικό που ο περισσότερος κόσμος δεν το σκέφτεται πια. Αγορές, άρθρα και η κατανάλωση περιεχομένου όπως βίντεο έχουν τουλάχιστον ένα κοινό, το οποίο είναι, πως όλα προτείνουν περιεχόμενο με βάση τα αποτελέσματα που έχουν προκύψει από αλγόριθμους εξόρυξης συχνών ομάδων αντικειμένων. Αυτοί οι μηχανισμοί εξόρυξης μας βοηθούν να βρούμε εστιατόρια ή δραστηριότητες που φαίνεται να μας ταιριάζουν χωρίς εμείς να έχουμε αναφέρει συγκεκριμένα κάτι που θέλουμε. Η εξόρυξη συχνών αντικειμένων ομαδοποιεί αντικείμενα με βάση τη συχνότητα με την οποία εμφανίζονται μαζί, και χρησιμοποιείται σε διάφορες εφαρμογές σε μια προσπάθεια να βελτιώσει την εμπειρία του χρήστη. Παλιότερες προσεγγίσεις εξόρυξης συχνών προτύπων έδιναν ικανοποιητικά αποτελέσματα παρότι δούλευαν με σχετικά λίγα δεδομένα. Καθώς όμως ο όγκος των διαθέσιμων δεδομένων συνεχώς αυξάνεται και οι σύγχρονες εφαρμογές απαιτούν την επεξεργασία όλο και περισσότερων δεδομένων, οι κλασικές κεντρικοποιημένες προσεγγίσεις φαίνεται να μην μπορούν επαρκώς να ανταποκριθούν. Ο σκοπός αυτής της πτυχιακής είναι ο σχεδιασμός και η υλοποίηση ενός κατανεμημένου συστήματος το οποίο θα μπορεί να βρίσκει ομάδες αντικειμένων που εμφανίζονται συχνά μαζι. Ξεκινάμε την προσπάθεια βρίσκοντας αυτές τις ομάδες σε μια κεντρικοποιημένη λύση και ύστερα μελετάμε τρόπους να κατανέμουμε τα δεδομένα και να βρούμε τις ίδιες ομάδες συχνά εμφανιζόμενων αντικειμένων. Ο στόχος μας είναι να πετύχουμε τη μεγαλύτερη δυνατή ακρίβεια μεταξύ των ομάδων που παράγονται από τη κατανεμημένη λύση με τις ομάδες που παράγονται από την κεντρικοποιημένη. Η κατανομή των δεδομένων μας δίνει την ευκαιρία να μελετήσουμε πιο περίπλοκα προβλήματα όπως είναι η σύνθεση πρωτεϊνών και φαρμάκων. Μπορούμε να βρούμε συσχετίσεις μεταξύ δεδομένων που δεν θα μπορούσαμε να διαχειριστούμε νωρίτερα όπως είναι η πρόβλεψη του καιρού και άλλα φυσικά φαινόμενα. Κάθε εμπόδιο που προσπερνάμε ανοίγει δυνατότητες για καινούργια και καλύτερα συστήματα τα οποία να παρέχουν πρόσβαση σε νέες τεχνολογίες

description: The coexistence of multiple ferroic orders, i.e. multiferroicity, is a scarce property to be found in materials. Historically, this state has been found mainly in 3-dimensional complex oxides, but so far this state has still been elusive for the most widely studied and characterized family of 2-dimensional compounds, the transition metal dichalcogenides. In this study we report the experimental realization of multiferroic states in this family of materials, at room temperature, in bulk single crystals of Te-doped WSe2. We observe the coexistence of ferromagnetism and ferroelectricity, evidenced in the presence of magnetization and piezoresponse force microscopy hysteresis loops. These findings open the possibility of widening the use and study of van der Waals-based multifunctional devices for new nanoelectronics and spintronics applications.

Use of Reiki for pain control in post-surgical patients: a critical review of the literature.
Creators: name: Jones, Jeremy
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2018

description: This critical review was conducted in order to evaluate the effect of
                    Reiki on postoperative pain given the increasing popularity of Integrative
                    medicine and growing need for unconventional approaches to pain control. The
                    review was conducted at the University of North Carolina at Chapel Hill. Online
                    databases were searched in Spring 2018 and identified five randomized controlled
                    trials meeting inclusion criteria. Risk of bias was evaluated with the Cochrane
                    risk of bias 2.0 tool. Four of five studies, with some concern for bias, showed
                    a statistically significant decrease in post-operative pain in Reiki groups
                    compared to sham-Reiki or control groups. There is evidence, with some concerns
                    for bias, that Reiki attunements can effectively reduce post-operative
                    pain.

Two-dimensional inflow-wind solution of black hole accretion with an evenly symmetric magnetic field

Subjects: subject: High Energy Astrophysical Phenomena (astro-ph.HE)

description: We solve the two-dimensional magnetohydrodynamic (MHD) equations of black hole accretion with the presence of magnetic field. The field includes a turbulent component, whose role is represented by the viscosity, and a large-scale ordered component. The latter is further assumed to be evenly symmetric with the equatorial plane. The equations are solved in the $r-θ$ plane of a spherical coordinate by assuming time-steady and radially self-similar. An inflow-wind solution is found. Around the equatorial plane, the gas is inflowing; while above and below the equatorial plane at a certain critical $θ$ angle, $θ\sim 47^{\circ}$, the inflow changes its direction of radial motion and becomes wind. The driving forces are analyzed and found to be the centrifugal force and the gradient of gas and magnetic pressure. The properties of wind are also calculated. The specific angular momentum of wind is found to be significantly larger than that of inflow, thus wind can transfer angular momentum outward. These analytical results are compared to those obtained by the trajectory analysis based on MHD numerical simulation data and good agreements are found.

Dataset vs Reality: Understanding Model Performance from the Perspective of Information Need

description: Deep learning technologies have brought us many models that outperform human beings on a few benchmarks. An interesting question is: can these models well solve real-world problems with similar settings (e.g., identical input/output) to the benchmark datasets? We argue that a model is trained to answer the same information need for which the training dataset is created. Although some datasets may share high structural similarities, e.g., question-answer pairs for the question answering (QA) task and image-caption pairs for the image captioning (IC) task, they may represent different research tasks aiming for answering different information needs. To support our argument, we use the QA task and IC task as two case studies and compare their widely used benchmark datasets. From the perspective of information need in the context of information retrieval, we show the differences in the dataset creation processes, and the differences in morphosyntactic properties between datasets. The differences in these datasets can be attributed to the different information needs of the specific research tasks. We encourage all researchers to consider the information need the perspective of a research task before utilizing a dataset to train a model. Likewise, while creating a dataset, researchers may also incorporate the information need perspective as a factor to determine the degree to which the dataset accurately reflects the research task they intend to tackle.
