description: We investigate entanglement mediated by DC current induced nonreciprocal graphene plasmon polaritons. Nonreciprocal systems are ideal for the enhancement, control, and preservation of entanglement due to the potential for unidirectional beam-like wave propagation, i.e., efficiently transporting photons from one emitter to another. Using a quantum master equation and three-dimensional Green's function analysis, we investigate a system consisting of two two-level emitters dominantly interacting via electric current induced nonreciprocal plasmonic modes of a graphene waveguide. We use concurrence as a measure of entanglement. We show that nonreciprocal graphene plasmon polaritons are a promising candidate to generate and mediate concurrence, where it is shown that there is good enhancement and control of entanglement over vacuum, which is beneficial for the broad applications of entanglement as a quantum resource. We believe our findings contribute to the development of quantum devices, enabling efficient and tunable entanglement between two-level systems, which is a central goal in quantum technologies.

Year: 2017

description: Health in All Policies (HiAP) is a policy strategy which improves population health and health inequities by addressing the social determinants of health. By centering on social determinants as root causes to produce the greatest impact on the community’s health, HiAP’s ecological approach differs from other models by concentrating on policy development and action by working across all governmental sectors, including non-traditional health-related entities. The City of Milwaukee Health Department is undergoing revisions of its policy agenda process while pondering adapting the HiAP concept into its strategic planning and operations.

description: Landau's phenomenological theory of Fermi liquids is a fundamental paradigm in many-body physics that has been remarkably successful in explaining the properties of a wide range of interacting fermion systems, such as liquid helium-3, nuclear matter, and electrons in metals. The d-dimensional boundaries of (d+1)-dimensional topological phases of matter such as quantum Hall systems and topological insulators provide new types of many-fermion systems that are topologically distinct from conventional d-dimensional many-fermion systems. We construct a phenomenological Landau theory for the two-dimensional helical Fermi liquid found on the surface of a three-dimensional time-reversal invariant topological insulator. In the presence of rotation symmetry, interactions between quasiparticles are described by ten independent Landau parameters per angular momentum channel, by contrast with the two (symmetric and antisymmetric) Landau parameters for a conventional spin-degenerate Fermi liquid. We then project quasiparticle states onto the Fermi surface and obtain an effectively spinless, projected Landau theory with a single projected Landau parameter per angular momentum channel that captures the spin-momentum locking or nontrivial Berry phase of the Fermi surface. As a result of this nontrivial Berry phase, projection to the Fermi surface can increase or lower the angular momentum of the quasiparticle interactions. We derive equilibrium properties, criteria for Fermi surface instabilities, and collective mode dispersions in terms of the projected Landau parameters. We briefly discuss experimental means of measuring projected Landau parameters.

Μέσα από την παρουσίαση αυτών των χαρακτήρων του μυθιστορήματος αλλά και από το σύνολο της ανάλυσης, γίνεται αντιληπτή η επιρροή του συγγραφέα από τον Ανρί Μπερξόν, τον Βίλχελμ Ντίλταϋ και τον Ιωάννη Συκουτρή. Επίσης, καταδεικνύεται η πίστη του συγγραφέα στην προσπάθεια αντίστασης των ανθρώπων απέναντι στην προδιαγεγραμμένη μοίρα τους, μέσα από ένα ταξίδι πνευματικής ανέλιξης, κατά το οποίο βρίσκουν τελικά το νόημα της ζωής τους με πρόταγμα την αγάπη και την πίστη στο πρόσωπο του ανθρώπου. Η εργασία δομείται στους εξής άξονες: Στα βιογραφικά στοιχεία του συγγραφέα, με κεντρική ιδέα την κατανόηση από μέρους του αναγνώστη των γεγονότων που κατά τη γνώμη μας σημάδεψαν τη ζωή του Γιώργου Θεοτοκά· στην παρουσίαση βασικών ιδεών του Βίλχελμ Ντίλταϋ και του Ανρί Μπερξόν, αλλά κυρίως στην ανάλυση της Φιλοσοφίας της Ζωής του Ιωάννη Συκουτρή· στις κοινωνικές και πολιτικές συνθήκες της εποχής που ώθησαν τον συγγραφέα στη συγγραφή του μυθιστορήματος· στην προσέγγιση και ανάλυση των βασικών χαρακτήρων του μυθιστορήματος, στην οποία δίδεται έμφαση· στην παράλληλη παρουσίαση των απόψεων του συγγραφέα και του Μαρίνου Βελή, με στόχο την ανάδειξη αυτού που ο ίδιος ο συγγραφέας είχε αναφέρει σχετικά με την επιθυμία του να μεταφέρει απόψεις και προβληματισμούς του μέσω ενός μυθιστορηματικού χαρακτήρα· στην προβολή, μέσω της παρουσίασης του μοναχού Τιμόθεου, της στροφής του συγγραφέα προς την Ορθοδοξία και της πεποίθησής του για την αναγκαιότητα της ύπαρξης της έννοιας της αγάπης ως στόχου ζωής, έννοια η οποία και αναλύεται.

The Increasing Incidence of Appendiceal Cancer: Hidden Complications of Non-Operative Management of Acute Appendicitis
Creators: name: Westfall, Kristen
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2018

description: Introduction: There has been a recent interest in the pursuit of non-operative management (NOM) of acute appendicitis in both pediatric and adult populations. One potential harm of NOM is overlooking cases of appendiceal cancer, a rare and often aggressive malignancy due to the frequency of late stage at diagnosis. Previous studies have reported an increasing incidence of appendiceal neoplasms in the population. Objective: This study aims to evaluate the incidence of primary appendiceal neoplasm among patients who presented with signs and symptoms of acute appendicitis at the University of North Carolina Memorial Hospital (UNC-MH) from 2011 to 2015. Methods: This is a retrospective case-control study of patients at UNC-MH who were treated with appendectomy for acute appendicitis. We evaluated the incidence of primary appendiceal cancer over time in this population and completed multivariate logistic regression analysis to determine factors that are associated with appendiceal cancer diagnosis. Results: Of the adult patients at UNC-MH presenting with clinically suspicious acute appendicitis, the incidence of appendiceal neoplasm was 2.8% (6/213) in 2011, 0.9% (2/209) in 2012, 3.0% (6/199) in 2013, 2.4% (4/170) in 2014, and 2.3% (5/216) in 2015. The incidence of appendiceal neoplasm over 5 years was 2.3% (23/1007) in this patient population. When considering only patients without appendiceal perforation on pathology, the incidence of appendiceal neoplasm over 5 years was 1.9% (16/832). Using a multivariate logistic regression, age (OR 1.03), number of days of abdominal pain (OR 1.16), self-reported fever (OR 2.08), appendiceal width (OR 1.95), and appendiceal wall thickness (OR 1.30) are associated with a primary appendiceal neoplasm diagnosis in patients that present with clinical signs and symptoms of acute appendicitis. Conclusions: We recommend that an operative approach to acute appendicitis should remain the standard of care, as operative management may not only be diagnostic but potentially therapeutic.

The simulations aimed at identifying the relevant local production and destruction rates for the p-nuclei of molybdenum and at determining the sensitivity of the final abundances to these rates. We show that local destruction rates strongly determine the abundance of $^{92}$Mo and $^{94}$Mo, and quantify the impact.

description: The Minkowski tensors (MTs) can be used to probe anisotropic signals in a field, and are well suited for measuring the redshift space distortion (RSD) signal in large scale structure catalogs. We consider how the linear RSD signal can be extracted from a field without resorting to the plane parallel approximation. A spherically redshift space distorted field is both anisotropic and inhomogeneous. We derive expressions for the two point correlation functions that elucidate the inhomogeneity, and then explain how the breakdown of homogeneity impacts the volume and ensemble averages of the tensor Minkowski functionals. We construct the ensemble average of these quantities in curvilinear coordinates and show that the ensemble and volume averages can be approximately equated, but this depends on our choice of definition of the volume average of a tensor and the radial distance between the observer and field. We then extract the tensor Minkowski functionals from spherically redshift space distorted, Gaussian random fields and gravitationally evolved dark matter density fields at $z=0$ to test if we can successfully measure the Kaiser RSD signal. For the dark matter field we find a significant, $\sim 10\%$ anomalous signal in the MT component parallel to the line of sight that is present even on large scales $R_{\rm G} \gtrsim 15 \, {\rm Mpc}$, in addition to the Kaiser effect. This is due to the line of sight component of the MT being significantly contaminated by the Finger of God effect, which can be approximately modelled by an additional damping term in the cumulants.

description: Der Beitrag betrachtet die südafrikanische Bioökonomie der Eizellspende als eine Fallstudie der ‚kontrollierten Einschaltung von Körpern in die (Re-)Produktionsapparate’ des Biokapitalismus. Er geht der Frage nach was genau in Wert gesetzt oder zur Ware wird und welche Rolle(n) der (re)produktive Körper dabei spielt. Dabei bringt er zwei bislang kaum aufeinander bezogene feministische Perspektiven auf die Materialität des Körpers zusammen: Feministische Ansätze in der Tradition feministischer Ökonomiekritik, welche die Inwertsetzung des Körpers in bioökonomischen Wertschöpfungsketten als naturalisierte clinical labour analysieren auf der einen Seite und Ansätze aus den STS, welche den Körper jenseits Cartesianischer Dualismen als Effekt der Intra-Aktion von Diskursen, Technologien und Materie denken auf der anderen. Basierend auf meiner ethnografischen Forschung in Südafrika zeigt meine Analyse die Komplexität des Verhältnisses von Körper und Arbeit im Fall der Eizellspende auf und verdeutlicht die Notwendigkeit eines fortgesetzten Dialogs zwischen ‚alten’ und ‚neuen’ feministischen Materialismen.

description: The Bekenstein-Hawking entropy is a cornerstone of horizon thermodynamics but quantum effects correct it, while inequivalent entropies arise also in non-extensive thermodynamics. Reviewing our previous work, we advocate for a new entropy construct that comprises recent and older proposals and satisfies four minimal key properties. The new proposal is then applied to black holes and to holographic dark energy and shown to have the potential to cause early universe inflation or to alleviate the current Hubble tension. We then analyze black hole temperatures and masses consistent with alternative entropies.

description: In this work, we systematically study the $ϕ$ meson and nucleus interaction by analyzing and fitting the cross sections of $γN$$\rightarrow ϕ$$N$ ($N$ represent the nucleus) reactions near the threshold. With the help of vector meson dominant model, the distribution of $ϕ$-$N$ scattering length as a function of energy is presented, and the results show that there is a slight increase in scattering length with increasing energy. Based on this, the average scattering length of $ϕ$-proton is obtained as $0.10\pm0.01$ fm by combining experimental data and theoretical models. Moreover, the average scattering length of $ϕ$-deuteron interaction is derived to be $0.014\pm0.002$ fm for the first time. Further, the effect of the momentum transfer $|t_{min}|$ on the $ϕ$-$N$ scattering length at the threshold is discussed. The obtained results not only provide important theoretical information for a more comprehensive and accurate study of the $ϕ$-$N$ scattering length, but also provide a basis for future experimental measurements of $ϕ$ meson production.

description: We consider the time-dependent analysis of rare $B_d$ and $B_s$ decays mediated by $b\to s ν\bar ν$ transitions. The inclusion of time evolution allows us to construct novel observables with specific sensitivity to CP-odd phases in these processes. The sensitivity to CP violation of corresponding time-integrated measurements in presence of flavor-tagging is also explored. We provide precise predictions for these observables in the SM and explore their sensitivity to new CP-violating NP contributions at present and planned future $B$-physics experiments. As such, these observables provide unique probes of CP violation in $b \to s ν\bar ν$ transitions.

description: Estimating the internal state of a robotic system is complex: this is performed from multiple heterogeneous sensor inputs and knowledge sources. Discretization of such inputs is done to capture saliences, represented as symbolic information, which often presents structure and recurrence. As these sequences are used to reason over complex scenarios, a more compact representation would aid exactness of technical cognitive reasoning capabilities, which are today constrained by computational complexity issues and fallback to representational heuristics or human intervention. Such problems need to be addressed to ensure timely and meaningful human-robot interaction. Our work is towards understanding the variability of learning informativeness when training on subsets of a given input dataset. This is in view of reducing the training size while retaining the majority of the symbolic learning potential. We prove the concept on human-written texts, and conjecture this work will reduce training data size of sequential instructions, while preserving semantic relations, when gathering information from large remote sources.

description: Στη σημερινή ψηφιακή εποχή, η αύξηση στον όγκο, την ποικιλομορφία και την ταχύτητα των δεδομένων έχει καταστήσει αναγκαία την αναζήτηση προηγμένων τεχνικών αποθήκευσης και ανάλυσης μεγάλων δεδομένων. Η συνεχής βελτίωση των υπολογιστών και η ανάπτυξη νέων τεχνολογιών για την αποθήκευση και επεξεργασία δεδομένων επεκτείνουν τις παραδοσιακές τεχνολογίες αποθήκευσης δεδομένων και πλαισίων ανάλυσης. Πολλοί οργανισμοί στρέφονται σε κατανεμημένα υπολογιστικά συστήματα για την επεξεργασία και ανάλυση μεγάλων συνόλων δεδομένων. Μία από τις πιο δημοφιλείς τεχνολογίες σε αυτόν τον τομέα είναι το Apache Spark, ένα γρήγορο και γενικής χρήσης σύστημα που λειτουργεί πάνω σε υπολογιστικούς κόμβους. Ωστόσο, τα παραδοσιακά σχεσιακά συστήματα βάσεων δεδομένων, όπως η Oracle, χρησιμοποιούνται ακόμα ευρέως για την αποθήκευση και ανάκτηση δεδομένων. Σε αυτήν την διπλωματική εργασία συγκρίνουμε την απόδοση ενός συγκεκριμένου συνόλου ερωτημάτων, πάνω σε ένα σύνολο δεδομένων συλλεγμένα από αισθητήρες οχημάτων, που εκτελέστηκαν τόσο σε ένα παραδοσιακό σύστημα σχεσιακής βάσης δεδομένων όσο και στο Apache Spark . Στόχος μας είναι να προσδιορίσουμε εάν οι σύγχρονες τεχνολογίες μπορούν να επιτύχουν ίση ή ακόμα καλύτερη απόδοση από τις σχεσιακές βάσεις δεδομένων όταν πρόκειται για την επεξεργασία και ανάλυση μεγάλων συνόλων δεδομένων, όπως στην περίπτωσή μας. Επιπλέον, η εργασία εξερευνά τις τεχνικές βελτιστοποίησης που μπορούν να χρησιμοποιηθούν για τη βελτίωση της απόδοσης του Spark καθώς και της Oracle.
Alpha decay in electron environments of increasing density: from the bare nucleus to compressed matter

description: The influence of the electron environment on the alpha decay is elucidated. Within the frame of a simple model based on the generalized Thomas-Fermi theory of the atom, it is shown that the increase of the electron density around the parent nucleus drives a mechanism which shortens the lifetime. Numerical results are provided for 144Nd, 154Yb and 210Po. Depending on the nuclide, fractional lifetime reduction relative to the bare nucleus is of the order of 0.1-1% in free ions, neutral atoms and ordinary matter, but may reach up to 10% at matter densities as high as 10^4 g/cm3, in a high-Z matrix. The effect induced by means of state-of-the-art compression techniques, although much smaller than previously found, would however be measurable. The extent of the effect in ultra-high-density stellar environments might become significant and would deserve further investigation.
Universal Oral Health Coverage, Changes in Policy

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

description: There is a pervasive trend within the healthcare industry wherein oral healthcare is isolated and viewed as removed from the medical model that treats the rest of the body. Part and parcel with this trend is the insurance industry and legislative bodies. The Affordable Care Act takes long overdue steps towards providing adequate coverage for those who were previously unable to afford comprehensive medical care. Meanwhile no reforms were made for privatized dental insurance and public dental insurance was changed in a positive yet underwhelming way, increasing Medicaid coverage from 100% of the Federal Poverty (FPL) level to 133% FPL. Limited access to dental insurance remains a significant factor for the underutilization of dental care among those populations that have the greatest prevalence of dental disease. Changes need to be made to the dental insurance system in order to be able to provide the appropriate level of care for those that do carry dental policies. Changes need to be made to the public system to reduce the number of people that currently cannot afford dental care due to its prohibitively expensive price tag. Most importantly changes need to be made to the culture of thinking regarding oral healthcare as an isolated entity that is entirely removed from the comprehensive medical picture. This paper reviews the current issues surrounding the inadequacy of dental care insurance coverage in the United States and presents a set of proposals and areas for future research to address the underutilization of needed dental care.
Estimating reddening of the continuum and broad-line region of active galactic nuclei: the mean reddening of NGC 5548 and the size of the accretion disc

description: We use seven different methods to estimate broad-line and continuum reddenings of NGC 5548. We investigate two possible reddening curves considered for active galactic nuclei (AGNs): the mean AGN reddening curve of Gaskell & Benker (2007) which is relatively flat in the ultraviolet, and a curve that rises strongly into the ultraviolet like a Small Magellanic Cloud (SMC) reddening curve. We also consider a standard Milky Way curve. Regardless of the curve adopted, we find a total reddening ~14 times greater than the small amount of reddening due to dust in the solar neighbourhood. The UV-to-optical ratios rule out a steep SMC-like reddening curve for NGC 5548. The Milky Way and Gaskell & Benker curves give a mean reddening of E(B-V) = 0.25 +/- 0.02. The four non-hydrogen-line reddening indicators imply that the intrinsic hydrogen line ratios are consistent with Baker-Menzel case B values. The unreddened optical-to-UV spectral energy distribution is consistent with the predicted distribution for an externally-illuminated accretion disc. The reddening we derive for NGC 5548 is typical of previous estimates for type-1 AGNs. Neglecting internal extinction leads to an underestimate of the luminosity at 1200 Angstroms by a factor of seven. The size scale of the accretion disc has therefore been underestimated by a factor of ~2.6. This is similar to the accretion disc size discrepancy found in the 2013 AGNSTORM campaign and thus supports the proposal by Gaskell (2017) that the accretion disc size discrepancy is primarily due to the neglect of reddening.

description: Στην παρούσα διπλωματική εργασία γίνεται ανάλυση της ποίησης του Θανάση Κωσταβάρα. Ο ποιητής γεννήθηκε το 1927 στο Βόλο και από πολύ μικρός εισχώρησε στον ΕΛΑΣ ακολουθώντας τον μεγαλύτερο αδερφό του. Οι πολιτικές του πεποιθήσεις τον έστειλαν εξόριστο στη Μακρόνησο, ένα μέρος που έπαιξε καθοριστικό ρόλο για τη συγγραφή των πρώτων του συλλογών. Μεγάλη συζήτηση έγινε για τον χαρακτηρισμό της ποίησης του ως «ποίηση της ήττας» με τον ίδιο να παίρνει θέση για τον όρο αυτό. Βέβαια ο έρωτας και το πάθος που έτρεφε για την σύζυγο του Αγγελική τον ώθησαν στη συγγραφή των πιο ερωτικών ποιημάτων γι’ αυτό και πολλοί κριτικοί του έργου του τον χαρακτήρισαν ως ερωτικό ποιητή. Τέλος και η ίδια η ποίηση τον απασχολούσε ιδιαίτερα καθώς μέσα σε πολλά ποιήματα του αναφέρει τις δυσκολίες που βιώνει ένας ποιητής για τη δημιουργία ενός ποιήματος που όμως τον αποζημιώνουν όταν τελικά προβεί στη δημιουργία του κάνοντας τον να νιώθει πως δεν μπορεί να ζήσει χωρίς αυτή.

description: The concept of inner friction, by which a quantum heat engine is unable to follow adiabatically its strokes and thus dissipates useful energy, is illustrated in an exact physical model where the working substance consists of an ensemble of misaligned spins interacting with a magnetic field and performing the Otto cycle. The effect of this static disorder under a finite-time cycle gives a new perspective of the concept of inner friction under realistic settings. We investigate the efficiency and power of this engine and relate its performance to the amount of friction from misalignment and to the temperature difference between heat baths. Finally we propose an alternative experimental implementation of the cycle where the spin is encoded in the degree of polarization of photons.

description: The exchange coupling between magnetic adsorbates and a superconducting substrate leads to Shiba states inside the superconducting energy gap and a Kondo resonance outside the gap. The exchange coupling strength determines whether the quantum many-body ground state is a Kondo singlet or a singlet of the paired superconducting quasiparticles. Here, we use scanning tunneling spectroscopy to identify the different quantum ground states of Manganese phthalocyanine on Pb(111). We observe Shiba states, which are split into triplets by magnetocrystalline anisotropy. Their characteristic spectral weight yields an unambiguous proof of the nature of the quantum ground state.

description: The dramatic first images with James Webb Space Telescope (JWST) demonstrated its power to provide unprecedented spatial detail for galaxies in the high-redshift universe. Here, we leverage the resolution and depth of the JWST Cosmic Evolution Early Release Science Survey (CEERS) data in the Extended Groth Strip (EGS) to perform pixel-level morphological classifications of galaxies in JWST F150W imaging using the Morpheus deep learning framework for astronomical image analysis. By cross-referencing with existing photometric redshift catalogs from the Hubble Space Telescope (HST) CANDELS survey, we show that JWST images indicate the emergence of disk morphologies before z~2 and with candidates appearing as early as z~5. By modeling the light profile of each object and accounting for the JWST point-spread function, we find the high-redshift disk candidates have exponential surface brightness profiles with an average Sersic (1968) index n=1.04 and >90% displaying "disky" profiles (n<2). Comparing with prior Morpheus classifications in CANDELS we find that a plurality of JWST disk galaxy candidates were previously classified as compact based on the shallower HST imagery, indicating that the improved optical quality and depth of the JWST helps to reveal disk morphologies that were hiding in the noise. We discuss the implications of these early disk candidates on theories for cosmological disk galaxy formation.
