description: We review the status and future of direct searches for light dark matter. We start by answering the question: `Whatever happened to the light dark matter anomalies?' i.e. the fate of the potential dark matter signals observed by the CoGeNT, CRESST-II, CDMS-Si and DAMA/LIBRA experiments. We discuss how the excess events in the first two of these experiments have been explained by previously underestimated backgrounds. For DAMA we summarise the progress and future of mundane explanations for the annual modulation reported in its event rate. Concerning the future of direct detection we focus on the irreducible background from solar neutrinos. We explain broadly how it will affect future searches and summarise efforts to mitigate its effects.

description: Path integrals are a central tool when it comes to describing quantum or thermal fluctuations of particles or fields. Their success dates back to Feynman who showed how to use them within the framework of quantum mechanics. Since then, path integrals have pervaded all areas of physics where fluctuation effects, quantum and/or thermal, are of paramount importance. Their appeal is based on the fact that one converts a problem formulated in terms of operators into one of sampling classical paths with a given weight. Path integrals are the mirror image of our conventional Riemann integrals, with functions replacing the real numbers one usually sums over. However, unlike conventional integrals, path integration suffers a serious drawback: in general, one cannot make non-linear changes of variables without committing an error of some sort. Thus, no path-integral based calculus is possible. Here we identify which are the deep mathematical reasons causing this important caveat, and we come up with cures for systems described by one degree of freedom. Our main result is a construction of path integration free of this longstanding problem, through a direct time-discretization procedure.

Outcomes of Acute Appendicitis at Kamuzu Central Hospital in Malawi as Compared to the University of North Carolina Memorial Hospital in North Carolina
Creators: name: Reiter, Audra
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2017

description: Introduction: Acute appendicitis is the most common gastrointestinal surgical emergency, and it is widely known that time to presentation is important to decrease the rate of perforation. Perforation of acute appendicitis is associated with increased morbidity such as abscess, wound infection, small bowel obstruction, and recurrent surgeries. The incidence of acute appendicitis has stabilized in western countries, but has been increasing in Asia, Africa, the Middle East, and Southern America. Objective: With lack of surgical infrastructure and delayed presentation to care in developing countries, this study aims to get a better understanding of the outcomes of acute appendicitis in Malawi at Kamuzu Central Hospital (KCH), a proxy for developing countries, as compared to North Carolina at the University of North Carolina Memorial Hospital (UNC-MH), a proxy for developed countries. Methods: I performed a retrospective chart review for all UNC-MH patients who underwent surgery for acute appendicitis from 2013 to 2015. To compare the UNC-MH patients to the KCH patients I extracted the information for patients with acute appendicitis from an acute care surgical database used at KCH in Lilongwe, Malawi. Demographics, initial vitals, and type of operative intervention were examined. In addition, analyses were performed on differences in time to hospital presentation, transfers, time to surgery, complications, length of stay, and mortality. Results: 738 patients with acute appendicitis were included in this study (17.2% from Malawi). Patients in Malawi were found to present to the hospital later (median of 75 vs. 24 hours), be taken to the operating room later (67.9% vs. 95.8% on same day), were more likely to be transferred to the central hospital (81.9% vs. 22.4%), and have longer lengths of stay (7 days vs. 1 day) as compared to patients in North Carolina. Mortality was also higher at KCH, at 7.1% as compared to 0% at UNC-MH. Conclusions: Acute appendicitis outcomes are significantly worse in Malawi than in North Carolina. There is a significantly longer delay to presentation after symptom onset in Malawi, which undoubtedly increases the risks for poor outcomes. This delay in presentation is most likely due to a deficient physician and surgical workforce in the country and long travel times to one of the few hospitals with surgical capabilities.

Screening for Dementia: A Review of the Evidence
Creators: name: Boustani, Malaz
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2002

description: Purpose: To review the evidence concerning screening for dementia syndrome (hereafter, dementia) in primary care settings to support recommendations from the US Preventive Services Task Force (USPSTF). Data Sources: We searched MEDLINE, PsychiNFO, EMBASE, and the Cochrane Collaboration Library from January 1994 to November 2001, with all searches limited to English language studies. Study Selection: We developed an analytic framework and key questions concerning dementia screening and treatment to guide our search. We developed inclusion and exclusion criteria for each key question. For questions of prevalence or accuracy of screening tests, we required cross-sectional or cohort studies in a primary care population with an acceptable reference standard for diagnosis. For questions of treatment, we included randomized controlled trials (RCTs) of subjects with mild to moderate dementia. Data Extraction: Two reviewers agreed on studies meeting inclusion and exclusion criteria and graded them according to USPSTF criteria. They then extracted data from included studies of fair to good quality and entered the data into evidence tables. Data Synthesis: The prevalence of dementia increases with age and affects 25% to 47% of people age 85 years and older. More than one-half of patients with dementia in primary care practices are undiagnosed. We found no RCT of screening for dementia. The Mini-Mental Status Examination (MMSE) is a brief screening tool with clinically acceptable reliability and accuracy. Although no effective treatment has yet been documented for early vascular dementia, cholinesterase inhibitors slow the rate of cognitive decline in people with mild to moderate Alzheimer's disease with mild adverse effects. Antidepressant medication is effective in reversing depressive symptoms in early dementia, but medical treatment of other behavioral and mood symptoms in early dementia is poorly studied. Intensive multi-component interventions for caregivers may delay nursing home placement and decrease caregiver burden, but they do not affect patients' health outcomes. Other benefits of screening and the potential harm of labeling have not been studied. Conclusion: Screening tests can detect undiagnosed dementia and cholinesterase inhibitors effectively slow the rate of cognitive decline in people with mild to moderate Alzheimer's disease. The effect of these drugs or other treatments on people with dementia detected by screening is uncertain.

description: We address the problem of causal discovery from data, making use of the recently proposed causal modeling framework of modular structural causal models (mSCM) to handle cycles, latent confounders and non-linearities. We introduce σ-connection graphs (σ-CG), a new class of mixed graphs (containing undirected, bidirected and directed edges) with additional structure, and extend the concept of σ-separation, the appropriate generalization of the well-known notion of d-separation in this setting, to apply to σ-CGs. We prove the closedness of σ-separation under marginalisation and conditioning and exploit this to implement a test of σ-separation on a σ-CG. This then leads us to the first causal discovery algorithm that can handle non-linear functional relations, latent confounders, cyclic causal relationships, and data from different (stochastic) perfect interventions. As a proof of concept, we show on synthetic data how well the algorithm recovers features of the causal graph of modular structural causal models.

Not Small. Minor
Creators: name: Bukova, Jana
Publisher: name: Studi Slavistici
Year: 2015

description: The A. challenges the belief in the oppositional potential of “small” literatures. An author’s choice to write in their own ‘minor’ language does not depend on whether the work takes part in the field of a minority, a small, a dominant or a world-hegemonic literature. Bukova conveys her commitment to the belief in a “literary literature” that can evade interpretation, ignore the rules of the market, the political heteronomy, or even the agenda of the discourse that is closest to the literary – of literary criticism. Such writers are generally only supported by translators. Bukova points at a niche that is doubly unprofitable but symbolically promising: to write literary literature in the language of a small literature. For “small” realities like Bulgarian literature, which are supported neither by the State nor by the media, the only chances to be ‘convertible’ consist in self-organisation of a literary field, struggling against market and geopolitical rationales and involving translators.

A Recommendation for Implementation of an Organizational Assessment Focused on Culture and Quality Improvement Strategies for Local Health Departments
Creators: name: Macchi, Marti
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2011

description: The mission of public health is to promote physical and mental health and prevent disease, injury and disability (Turnock, 2009). This mission requires significant collaboration between local, state and federal level agency practitioners. The public health challenges in the 21st century will be most effectively addressed by practitioners that proactively prepare to meet them through strategies such as workforce development, community engagement, and evidence-based practice. Local Health Departments (LHD) are tasked to meet the health needs of the public at the local level and face many challenges in fulfilling the public health mission. These challenges include managing financial constraints, developing capacity, ensuring workforce training, and providing leadership. An organizational assessment of the culture of a LHD, coupled with the accreditation (including a community health assessment process) can enhance the LHDs ability to meet the needs of their community by focusing on improving critical community health outcomes and applying evidence-based strategies to achieve goals. This paper focuses on an organizational assessment of a Local Health Department (LHD) to identify gaps in performance and opportunities for the application of quality improvement approaches and evidence-based practices to improve the organizational culture in which public health practitioners carry out the public health mission. In addition to a literature review, experiences and lessons learned from an organizational assessment in a North Carolina LHD will be highlighted to propose recommendations for incorporating an organizational assessment focused on culture into an overall accreditation process utilizing evidence-based interventions and quality improvement strategies. A variety of supports and resources are available to a LHD to address areas of performance and improve quality. In this paper a literature review will describe these supports and a case study will describe application of current supports and resources with the addition of an organizational assessment addressing culture and its role in performance and health outcomes.
Towards Paired Histories of Small Literatures, To Make Them Communicate
Creators: name: Ljuckanov, Jordan
Publisher: name: Studi Slavistici
Year: 2015

description: The A. suggests a geo-cultural relocation of Bulgarian literature, within an agenda of reforming comparative literature studies. First, comparative literature should develop an awareness of the cultural worlds which, being neither metropolitan nor colonial, benefited insubstantially from the post-colonial turn in humanities. It should leave the “universalist” perspective behind and commit to a “communitarianist” perspective, trying a synthesis between Dionýz Ďurišin’s theory of interliterary communities and Pierre Bourdieu’s theory of the cultural field. In a pragmatical communitarianist epistemology experts affiliated to scholarly institutions belonging to, for example, the Black Sea states, should start producing expertise on the Black Sea region. This may lead to overcoming the neo-colonised status of, for example, Bulgarian scholarship vis-à-vis the international division of scholarly labour and, subsequently, to a reformed state of the collective mind of the Bulgarian cultural field. Such a geo-cultural relocation of Bulgarian literature to a hypothetic cross-Black Sea interliterary community, or at least neighbourhood, could be both a means for and a side-effect of the invoked act of emancipation.

description: EDGE-based EC-GSM-IoT is a promising candidate for the billion-device cellular IoT (cIoT), providing similar coverage and battery life as NB-IoT. The goal of 20 dB coverage extension compared to EDGE poses significant challenges for the initial network synchronization, which has to be performed well below the thermal noise floor, down to an SNR of -8.5 dB. We present a low-complexity synchronization algorithm supporting up to 50 kHz initial frequency offset, thus enabling the use of a low-cost +/-25 ppm oscillator. The proposed algorithm does not only fulfill the 3GPP requirements, but surpasses them by 3 dB, enabling communication with an SNR of -11.5 dB or a maximum coupling loss of up to 170.5 dB.

description: Vertical and lateral heterogeneous structures of two-dimensional (2D) materials have paved the way for pioneering studies on the physics and applications of 2D materials. A hybridized hexagonal boron nitride (h-BN) and graphene lateral structure, a heterogeneous 2D structure, has been fabricated on single-crystal metals or metal foils by chemical vapor deposition (CVD). However, once fabricated on metals, the h-BN/graphene lateral structures require an additional transfer process for device applications, as reported for CVD graphene grown on metal foils. Here, we demonstrate that a single-crystal h-BN/graphene lateral structure can be epitaxially grown on a wide-gap semiconductor, SiC(0001). First, a single-crystal h-BN layer with the same orientation as bulk SiC was grown on a Si-terminated SiC substrate at 850 oC using borazine molecules. Second, when heated above 1150 oC in vacuum, the h-BN layer was partially removed and, subsequently, replaced with graphene domains. Interestingly, these graphene domains possess the same orientation as the h-BN layer, resulting in a single-crystal h-BN/graphene lateral structure on a whole sample area. For temperatures above 1600 oC, the single-crystal h-BN layer was completely replaced by the single-crystal graphene layer. The crystalline structure, electronic band structure, and atomic structure of the h-BN/graphene lateral structure were studied by using low energy electron diffraction, angle-resolved photoemission spectroscopy, and scanning tunneling microscopy, respectively. The h-BN/graphene lateral structure fabricated on a wide-gap semiconductor substrate can be directly applied to devices without a further transfer process, as reported for epitaxial graphene on a SiC substrate.

Year: 2018

description: Human Centered Design (HCD) has been growing in popularity in public health for the past several years. This methodology is an ethical approach to working with target populations and results in effective products and services.  However, to date there has been limited literature exploring how to evaluate the fidelity of a given design process with the principles of HCD. This paper will explore the implementation of the HCD process that Shifra, a small community based organization (CBO) in Melbourne, Australia, undertook when creating a web application (app) to improve refugees’ and asylum seekers' access to sexual and reproductive health services. The paper will then detail the development of an implementation evaluation plan including data collection and results, and offer recommendations for Shifra moving forward.

description: Causal discovery algorithms infer causal relations from data based on several assumptions, including notably the absence of measurement error. However, this assumption is most likely violated in practical applications, which may result in erroneous, irreproducible results. In this work we show how to obtain an upper bound for the variance of random measurement error from the covariance matrix of measured variables and how to use this upper bound as a correction for constraint-based causal discovery. We demonstrate a practical application of our approach on both simulated data and real-world protein signaling data.

description: Let $(\mathscr{X}$, $\mathscr{Y})$ be a balanced pair in an abelian category. We first introduce the notion of cotorsion pairs relative to $(\mathscr{X}$, $\mathscr{Y})$, and then give some equivalent characterizations when a relative cotorsion pair is hereditary or perfect. We prove that if the $\mathscr{X}$-resolution dimension of $\mathscr{Y}$ (resp. $\mathscr{Y}$-coresolution dimension of $\mathscr{X}$) is finite, then the bounded homotopy category of $\mathscr{Y}$ (resp. $\mathscr{X}$) is contained in that of $\mathscr{X}$ (resp. $\mathscr{Y}$). As a consequence, we get that the right $\mathscr{X}$-singularity category coincides with the left $\mathscr{Y}$-singularity category if the $\mathscr{X}$-resolution dimension of $\mathscr{Y}$ and the $\mathscr{Y}$-coresolution dimension of $\mathscr{X}$ are finite.

description: Ionic substitution forms an essential pathway to manipulate the carrier density and crystalline symmetry of materials via ion-lattice-electron coupling, leading to a rich spectrum of electronic states in strongly correlated systems. Using the ferromagnetic metal SrRuO3 as a model system, we demonstrate an efficient and reversible control of both carrier density and crystalline symmetry through the ionic liquid gating induced protonation. The insertion of protons electron-dopes SrRuO3, leading to an exotic ferromagnetic to paramagnetic phase transition along with the increase of proton concentration. Intriguingly, we observe an emergent topological Hall effect at the boundary of the phase transition as the consequence of the newly-established Dzyaloshinskii-Moriya interaction owing to the breaking of inversion symmetry in protonated SrRuO3 with the proton compositional film-depth gradient. We envision that electric-field controlled protonation opens a novel strategy to design material functionalities.

description: In industrial applications, nearly half the failures of motors are caused by the degradation of rolling element bearings (REBs). Therefore, accurately estimating the remaining useful life (RUL) for REBs are of crucial importance to ensure the reliability and safety of mechanical systems. To tackle this challenge, model-based approaches are often limited by the complexity of mathematical modeling. Conventional data-driven approaches, on the other hand, require massive efforts to extract the degradation features and construct health index. In this paper, a novel online data-driven framework is proposed to exploit the adoption of deep convolutional neural networks (CNN) in predicting the RUL of bearings. More concretely, the raw vibrations of training bearings are first processed using the Hilbert-Huang transform (HHT) and a novel nonlinear degradation indicator is constructed as the label for learning. The CNN is then employed to identify the hidden pattern between the extracted degradation indicator and the vibration of training bearings, which makes it possible to estimate the degradation of the test bearings automatically. Finally, testing bearings' RULs are predicted by using a $ε$-support vector regression model. The superior performance of the proposed RUL estimation framework, compared with the state-of-the-art approaches, is demonstrated through the experimental results. The generality of the proposed CNN model is also validated by transferring to bearings undergoing different operating conditions.

description: Background: People with Multiple Sclerosis (MS) have unique housing and support needs that are essential for maintaining independence at home; however, there is limited research to guide the design of community living options for this population. The aim of this study was to examine housing and support needs and preferences of people with MS with the intention to inform the planning of a co-designed intervention based on the study's findings. Methods: Using the Knowledge to Action (KTA) framework, quantitative (n = 79) and qualitative (n = 6) data from people with MS were extracted and integrated from projects completed by the research team that explored the housing and support needs and preferences of people with disability. Results were synthesised and presented to a reference group for validation, contextualisation, and adaptation to the Australian context. Results: High physical support needs were common across participants. People most commonly required home modifications to improve accessibility, such as ramps, equipment such as heating and cooling, and assistive technology. Many people required more than 8 hours per day of paid support. Moving into individualised housing facilitated independence and community reintegration. People reported gaps between what they wanted from support workers and what they received, citing individual and systemic barriers. Conclusion: People with MS have support needs that require proactive and responsive funding arrangements, housing design and support provision. In line with KTA principles, findings will inform the planning of a co-designed intervention that involves people with lived experience of MS and other stakeholders to influence policy and improve home and living outcomes for this population.

description: We prove the main rules of causal calculus (also called do-calculus) for i/o structural causal models (ioSCMs), a generalization of a recently proposed general class of non-/linear structural causal models that allow for cycles, latent confounders and arbitrary probability distributions. We also generalize adjustment criteria and formulas from the acyclic setting to the general one (i.e. ioSCMs). Such criteria then allow to estimate (conditional) causal effects from observational data that was (partially) gathered under selection bias and cycles. This generalizes the backdoor criterion, the selection-backdoor criterion and extensions of these to arbitrary ioSCMs. Together, our results thus enable causal reasoning in the presence of cycles, latent confounders and selection bias. Finally, we extend the ID algorithm for the identification of causal effects to ioSCMs.

description: Time dispersion of the radio channel is an important characteristics in waveform and other system design of wireless communication links. In this TD we present delay spreads and maximum excess delays analysed using data from single directional propagation measurements at 140 GHz radio frequency in both outdoor and indoor environments. Since upper mm-wave radio links necessitate high antenna gains, we consider beam steered radio channel as the basis of our analysis, i.e., beam gains are multiplied with the measured propagation path gains prior to the analysis. Preliminary results show 1.5–11 ns median rms delay spreads and 23–110 ns median values of maximum excess delays, depending on the LOS/NLOS condition, environment, link distance, and used beam width.

description: The manufacturing sector is envisioned to be heavily influenced by artificial intelligence-based technologies with the extraordinary increases in computational power and data volumes. A central challenge in manufacturing sector lies in the requirement of a general framework to ensure satisfied diagnosis and monitoring performances in different manufacturing applications. Here we propose a general data-driven, end-to-end framework for the monitoring of manufacturing systems. This framework, derived from deep learning techniques, evaluates fused sensory measurements to detect and even predict faults and wearing conditions. This work exploits the predictive power of deep learning to automatically extract hidden degradation features from noisy, time-course data. We have experimented the proposed framework on ten representative datasets drawn from a wide variety of manufacturing applications. Results reveal that the framework performs well in examined benchmark applications and can be applied in diverse contexts, indicating its potential use as a critical corner stone in smart manufacturing.

description: We develop a physically motivated, spherical corona model to investigate the frequency-dependent time lags in AGN. The model includes the effects of Compton up-scattering between the disc UV photons and coronal electrons, and the subsequent X-ray reverberation from the disc. The time lags are associated with the time required for multiple scatterings to boost UV photons up to soft and hard X-ray energies, and the light crossing time the photons take to reach the observer. This model can reproduce not only low-frequency hard and high-frequency soft lags, but also the clear bumps and wiggles in reverberation profiles which should explain the wavy-residuals currently observed in some AGN. Our model supports an anti-correlation between the optical depth and coronal temperatures. In case of an optically thin corona, time delays due to propagating fluctuations may be required to reproduce observed time lags. We fit the model to the lag-frequency data of 1H0707-495, Ark 564, NGC 4051 and IRAS 13224-3809 estimated using the minimal bias technique so that the observed lags here are highest-possible quality. We find their corona size is ~7-15 r_g having the constrained optical depth ~2-10. The coronal temperature is ~150-300 keV. Finally, we note that the reverberation wiggles may be signatures of repeating scatters inside the corona that control the distribution of X-ray sources.

description: Σκοπός της εργασίας είναι η διερεύνηση της επιρροής της επιδημίας χολέρας στο αρχιτεκτονικό και αστικό περιβάλλον της Αθήνας και του Πειραιά, από το 1854 ως το 1856.
Τα ευρήματα παρουσιάζονται σε ενότητες, οι οποίες διαρθρώνονται  ως εξής: παρατίθενται τα μέτρα που εφαρμόστηκαν για τον περιορισμό της εξάπλωσης της ασθένειας, οι παρεμβάσεις που πραγματοποιήθηκαν σε αστική κλίμακα, ο αρχιτεκτονικός αντικατοπτρισμός της επιδημίας, δηλαδή τα κτήρια που κατασκευάστηκαν για να καλύψουν τις ανάγκες που προέκυψαν και τα κτήρια που μετασκευάστηκαν ώστε να προσαρμοστεί η λειτουργία τους. Τέλος παρουσιάζονται μαρτυρίες ταξιδευτών και κατοίκων των περιοχών που έπληξε η χολέρα, καθώς και οι καταγραφές στον τύπο της εποχής.
Η πανδημία ασιατικής χολέρας φτάνει στον Πειραιά μέσω των γαλλικών και αγγλικών στρατευμάτων που κατέκτησαν το λιμάνι κατά τη διάρκεια του Κριμαϊκού πολέμου. Πρόκειται για την εποχή κατά την οποία το ελληνικό κράτος είναι νεοσύστατο, συνεπώς οι ελλείψεις που αφορούν στις υποδομές και την υγειονομική οργάνωση είναι αισθητές.
Η συμβολή των ευεργετών στην περίθαλψη ασθενών και τη στέγαση των ορφανών είναι κάθε άλλο παρά αμελητέα. Οι ελλείψεις του κράτους συμπληρώνονται από την ευεργεσία Ελλήνων που προσφέρουν υποδομές και χρήματα υπέρ της ίδρυσης και της λειτουργίας νοσοκομείων και ορφανοτροφείων. Έτσι στο χάρτη της Αθήνας και του Πειραιά παρατηρείται η πύκνωση των κτηρίων και των εγκαταστάσεων που αφορούν στην πρόληψη της εξάπλωσης μολυσματικών ασθενειών και την περίθαλψη αρρώστων. Τυπολογικά, δεν παρατηρούνται ακόμα αλλαγές, όμως υπήρξε προσπάθεια για τη βελτίωση των υποδομών ύδρευσης και αποχέτευσης, την ενημέρωση των πολιτών για τη σημασία των επαρκών συνθηκών υγιεινής και την παροχή δωρεάν υπηρεσιών πρόνοιας.

description: We introduce and study a class of particle hopping models consisting of a single box coupled to a pair of reservoirs. Despite being zero-dimensional, in the limit of large particle number and long observation time, the current and activity large deviation functions of the models can exhibit symmetry-breaking dynamical phase transitions. We characterize exactly the critical properties of these transitions, showing them to be direct analogues of previously studied phase transitions in extended systems. The simplicity of the model allows us to study features of dynamical phase transitions which are not readily accessible for extended systems. In particular, we quantify finite-size and finite-time scaling exponents using both numerical and theoretical arguments. Importantly, we identify an analogue of critical slowing near symmetry breaking transitions and suggest how this can be used in the numerical studies of large deviations. All of our results are also expected to hold for extended systems.
