description: We perform numerical experiments on the Serre-Green-Naghdi (SGN) equations and a fully dispersive "Whitham-Green-Naghdi" (WGN) counterpart in dimension 1. In particular, solitary wave solutions of the WGN equations are constructed and their stability, along with the explicit ones of the SGN equations, is studied. Additionally, the emergence of modulated oscillations and the possibility of a blow-up of solutions in various situations is investigated.
 We argue that a simple numerical scheme based on a Fourier spectral method combined with the Krylov subspace iterative technique GMRES to address the elliptic problem and a fourth order explicit Runge-Kutta scheme in time allows to address efficiently even computationally challenging problems.

description: There has been much debate about whether intercollegiate athletics fits into the educational mission of higher learning (McCormick & McCormick, 2008; Sack & Staurowsky, 1998). This study utilized the educational value of intercollegiate athletics (Brand, 2006) as a conceptual framework to determine the alignment of intercollegiate athletic participation with the goals of higher education. A survey of former student-athletes and non-athletes from a renowned public university in the Southeastern United States revealed the differences in occupational outcomes, such as, job satisfaction, salary, and work engagement, between these two cohorts. The results of this study will add to the literature examining the occupational impacts of intercollegiate athletics participation. It will also add to existing literature by helping to support the argument that college athletics prepares student-athletes for the workforce.

description: The idea of a hierarchical spatial organization of society lies at the core of seminal theories in human geography that have strongly influenced our understanding of social organization. In the same line, the recent availability of large-scale human mobility and communication data has offered novel quantitative insights hinting at a strong geographical confinement of human interactions within neighboring regions, extending to local levels within countries. However, models of human interaction largely ignore this effect. Here, we analyze several country-wide networks of telephone calls and uncover a systematic decrease of communication induced by borders which we identify as the missing variable in state-of-the-art models. Using this empirical evidence, we propose an alternative modeling framework that naturally stylize the damping effect of borders. We show that this new notion substantially improves the predictive power of widely used interaction models, thus increasing our ability to predict social activities and to plan the development of infrastructures across multiple scales.

description: The purposes of this study were 1) to determine the knowledge of dental practitioners on the clinical signs, etiology, and treatment of dental erosion, 2) to determine the prevalence of dental erosion in a population of subjects with Gastroesophageal Reflux Disease (GERD) as compared to a control population, and 3) to determine the association of number of acidic challenges, number of medications, age, salivary buffering capacity, initial salivary pH, and salivary flow rate to the erosive tooth wear (ETW) present. Results indicate that 1) while dental practitioners can identify the signs of dental erosion with a 36% accuracy, various etiologies and preventive treatment options are being overlooked, 2) the prevalence of erosion in a population of GERD subjects is 40% as compared to 15% in a control population, and 3) the only association seen is an increase of ETW with an increase in age.

description: We report on the detection of pulsations of three pulsating subdwarf B stars observed by the TESS satellite and our results of mode identification in these stars based on an asymptotic period relation. SB 459 (TIC 067584818), SB 815 (TIC 169285097) and PG 0342+026 (TIC 457168745) have been monitored during single sectors resulting in 27 days coverage. These datasets allowed for detecting, in each star, a few tens of frequencies, which we interpreted as stellar oscillations. We found no multiplets, though we partially constrained mode geometry by means of period spacing, which recently became a key tool in analyses of pulsating subdwarf B stars. Standard routine that we have used allowed us to select candidates for trapped modes that surely bear signatures of non-uniform chemical profile inside the stars. We have also done statistical analysis using collected spectroscopic and asteroseismic data of previously known subdwarf B stars along with our three stars. Making use of high precision trigonometric parallaxes from the Gaia mission and spectral energy distributions we converted atmospheric parameters to stellar ones. Radii, masses and luminosities are close to their canonical values for extreme horizontal branch stars. In particular, the stellar masses are close to the canonical one of 0.47 M$_\odot$ for all three stars but uncertainties on the mass are large. The results of the analyses presented here will provide important constrains for asteroseismic modelling.

description: We report Gemini Planet Imager H band high-contrast imaging/integral field spectroscopy and polarimetry of the HD 100546, a 10 $Myr$-old early-type star recently confirmed to host a thermal infrared bright (super)jovian protoplanet at wide separation, HD 100546 b. We resolve the inner disk cavity in polarized light, recover the thermal-infrared (IR) bright arm, and identify one additional spiral arm. We easily recover HD 100546 b and show that much of its emission originates an unresolved, point source. HD 100546 b likely has extremely red infrared colors compared to field brown dwarfs, qualitatively similar to young cloudy superjovian planets, however, these colors may instead indicate that HD 100546 b is still accreting material from a circumplanetary disk. Additionally, we identify a second point source-like peak at $r_{proj}$ $\sim$ 14 AU, located just interior to or at inner disk wall consistent with being a 10--20 $M_{J}$ candidate second protoplanet-- "HD 100546 c" -- and lying within a weakly polarized region of the disk but along an extension of the thermal IR bright spiral arm. Alternatively, it is equally plausible that this feature is a weakly polarized but locally bright region of the inner disk wall. Astrometric monitoring of this feature over the next 2 years and emission line measurements could confirm its status as a protoplanet, rotating disk hot spot that is possibly a signpost of a protoplanet, or a stationary emission source from within the disk.

description: We report a development of a multi-color simultaneous camera for the 188cm telescope at Okayama Astrophysical Observatory in Japan. The instrument, named MuSCAT, has a capability of 3-color simultaneous imaging in optical wavelength where CCDs are sensitive. MuSCAT is equipped with three 1024x1024 pixel CCDs, which can be controlled independently. The three CCDs detect lights in $g'_2$ (400--550 nm), $r'_2$ (550--700 nm), and $z_{s,2}$ (820--920 nm) bands using Astrodon Photometrics Generation 2 Sloan filters. The field of view of MuSCAT is 6.1x6.1 arcmin$^2$ with the pixel scale of 0.358 arcsec per pixel. The principal purpose of MuSCAT is to perform high precision multi-color transit photometry. For the purpose, MuSCAT has a capability of self autoguiding which enables to fix positions of stellar images within ~1 pix. We demonstrate relative photometric precisions of 0.101%, 0.074%, and 0.076% in $g'_2$, $r'_2$, and $z_{s,2}$ bands, respectively, for GJ436 (magnitudes in $g'$=11.81, $r'$=10.08, and $z'$=8.66) with 30 s exposures. The achieved precisions meet our objective, and the instrument is ready for operation.

description: We complete a full classification of non-degenerate traveling waves of scalar balance laws from the point of view of spectral and nonlinear stability/instability under (piecewise) smooth perturbations. A striking feature of our analysis is the elucidation of the prominent role of characteristic points in the determination of both the spectra of the linearized operators and the phase dynamics involved in the nonlinear large-time evolution. For a generic class of equations an upshot of our analysis is a dramatic reduction from a tremendously wide variety of entropic traveling waves to a relatively small range of stable entropic traveling waves.

description: Recently frequent and sequential pattern mining algorithms have been widely used in the field of software engineering to mine various source code or specification patterns. In practice software evolves from one version to another is needed for providing extra facilities to user. This kind of task is challenging in this domain since the database is usually updated in all kinds of manners such as insertion, various modifications as well as removal of sequences. If database is optimized then this optimized information will help developer in their development process and save their valuable time as well as development expenses. Some existing algorithms which are used to optimize database but it does not work faster when database is incrementally updated. To overcome this challenges an efficient algorithm is recently introduce, called the Canonical Order Tree that captures the content of the transactions of the database and orders. In this paper we have proposed a technique based on the Canonical Order Tree that can find out frequent patterns from the incremental database with speedy and efficient way. Thus the database will be optimized as well as it gives useful information to recommend software developer.

My heart sings to me: song as the memory of language in the Arbëresh community of Chieuti
Creators: name: Bell, Sara Jane
Publisher: name: University of North Carolina at Chapel Hill
Year: 2011

description: For the people of Chieuti who grew up speaking the Albanian dialect that the inhabitants of their Arbëresh town in the Italian province of Puglia have spoken for more than five centuries, the rapid decline of their mother tongue is a loss that is sorely felt. Musicians and cultural activists labor to negotiate new strategies for maintaining connections to their unique heritage and impart their traditions to young people who are raised speaking Italian in an increasingly interconnected world. As they perform, they are able to act out collective narratives of longing and belonging, history, nostalgia, and sense of place. Using the traditional song Rine Rine as a point of departure, this thesis examines how songs transmit linguistic and cultural markers of Arbëresh identity and serve to illuminate Chieuti's position as a community poised in the moment of language shift.

description: Standard perturbative quantum gravity formalism is applied to compute the lowest order corrections to the spatially flat cosmological FLRW solution governed by ordinary matter. The presented approach is analogous to the one used to compute quantum corrections to the Coulomb potential in electrodynamics, or to the approach applied in computation of quantum corrections to the Schwarzschild solution in gravity. In this framework, it is shown that the corrections to the classical metric coming from the one-loop graviton vacuum polarization (self-energy) have (UV cutoff dependent) repulsive properties, which could be not negligible in the very early Universe.

description: The jets of SS 433 have punched through the supernova remnant from the explosion forming the compact object. The precessing jets collimate before reaching beyond the shell, some 40 pc downstream, just the region of origin of TeV gamma radiation. Collimation could be effected by ambient pressure in the SNR cavity; I investigate conditions under which W50 morphology and the origins of TeV gamma radiation can be explained in terms of collimation, with associated shocks, induced by ambient pressure. I consider the age of the SNR and hence the present ambient pressure. The cavity is now ~ 10^5 years after the supernova; with lower pressure, collimation and associated shocks would occur ~40 pc downstream, just the origin of TeV gamma radiation. Modelling of evolution of binary systems indicates that Roche lobe overflow and initiation of the jets is recent. Collimation would still occur ~40 pc downstream, but the cone angle of the precession must then have increased with time - driven by the Roche lobe overflow. The morphology of W50 and the site of the origin of TeV gamma radiation are readily explained in terms of collimation of the jets by internal SNR pressure.

Research protocol. Worldwide trends in sodium and potassium intakes in children and adolescents: a systematic review and meta-analysis

Publisher: name: Zenodo
Year: 2023

description: Intakes of sodium (Na) and potassium (K) are key determinants of health and diseases from birth to adulthood. High Na intake is a cause of elevated blood pressure and cardiovascular diseases, and is associated with other conditions such as osteoporosis, diabetes, and cancer. Low K intake is associated with elevated blood pressure and cardiovascular diseases, as well as with chronic kidney stone formation and low bone-mineral density. An adequate intake of Na and K starting in childhood has the potential to ensure an optimal life course trajectory and to prevent high blood pressure later in life. The objective of this systematic review is to estimate global, regional, and national trends in Na and K intakes (primary outcome) and Na/K intake ratio (secondary outcome) in children and adolescents. We aim to produce worldwide maps of Na and K intakes in children in 1990, 2000, 2010 and 2020.

For understanding the mechanism of the high superconductivity, the information of its crystal structure is very essential. Herein we have carried out the simultaneous measurements electrical resistance and synchrotron x-ray diffraction under high pressure, and clearly revealed that the hydrogen sulfide, H2S, decomposes to H3S and its crystal structure has body-centered cubic symmetry in the superconducting phase.

description: The ongoing pandemic of SARS-CoV-2 calls for rapid and cost-effective methods to accurately identify infected individuals. The vast majority of patient samples is assessed for viral RNA presence by RT-qPCR. Our biomedical research institute, in collaboration between partner hospitals and an accredited clinical diagnostic laboratory, established a diagnostic testing pipeline that has reported on more than 252,000 RT-qPCR results since its commencement at the beginning of April 2020. However, due to ongoing demand and competition for critical resources, alternative testing strategies were sought. In this work, we present a clinically-validated procedure for high-throughput SARS-CoV-2 detection by RT-LAMP in 25 minutes that is robust, reliable, repeatable, sensitive, specific, and inexpensive.
Evaluating the efficacy of grafting the facial gap at immediately placed implants in the anterior maxilla: a systematic review and randomized controlled trial
Creators: name: Jacobs, Bryan
Publisher: name: University of North Carolina at Chapel Hill
Year: 2013

description: Immediate implant placement is an accepted and widely utilized treatment modality for tooth replacement following extraction. Survival and success are comparable to implant placement in healed ridges. However, the best methods for achieving predictable soft tissue esthetics are still up for debate. Contemporary surgical strategy often leaves a facial gap anterior to the implant, between it and the buccal plate. The ideal management of this gap--with regards to grafting or not--has not been clearly defined. There are two general aims to this thesis: to review immediate implant literature that examines esthetic outcomes based on facial gap grafting status, and to carry out a randomized, controlled trial evaluating whether grafting the facial gap between the implant and buccal bone at the time of immediate implant placement will improve tissue preservation when compared to a no-grafting protocol.

description: We build a bijection between the set $\sttiltΛ$ of isomorphism classes of basic support $τ$-tilting modules over the Auslander algebra $Λ$ of $K[x]/(x^n)$ and the symmetric group $\mathfrak{S}_{n+1}$, which is an anti-isomorphism of partially ordered sets with respect to the generation order on $\sttiltΛ$ and the left order on $\mathfrak{S}_{n+1}$. This restricts to the bijection between the set $\tiltΛ$ of isomorphism classes of basic tilting $Λ$-modules and the symmetric group $\mathfrak{S}_n$ due to Brüstle, Hille, Ringel and Röhrle. Regarding the preprojective algebra $Γ$ of Dynkin type $A_n$ as a factor algebra of $Λ$, we show that the tensor functor $-\otimes_ΛΓ$ induces a bijection between $\sttiltΛ\to\sttiltΓ$. This recover Mizuno's bijection $\mathfrak{S}_{n+1}\to\sttiltΓ$ for type $A_n$.

description: Memes are graphics and text overlapped so that together they present concepts that become dubious if one of them is absent. It is spread mostly on social media platforms, in the form of jokes, sarcasm, motivating, etc. After the success of BERT in Natural Language Processing (NLP), researchers inclined to Visual-Linguistic (VL) multimodal problems like memes classification, image captioning, Visual Question Answering (VQA), and many more. Unfortunately, many memes get uploaded each day on social media platforms that need automatic censoring to curb misinformation and hate. Recently, this issue has attracted the attention of researchers and practitioners. State-of-the-art methods that performed significantly on other VL dataset, tends to fail on memes classification. In this context, this work aims to conduct a comprehensive study on memes classification, generally on the VL multimodal problems and cutting edge solutions. We propose a generalized framework for VL problems. We cover the early and next-generation works on VL problems. Finally, we identify and articulate several open research issues and challenges. This is the first study that presents the generalized view of the advanced classification techniques concerning memes classification to the best of our knowledge. We believe this study presents a clear road-map for the Machine Learning (ML) research community to implement and enhance memes classification techniques.

description: We report a systematic study of coherent spin precession and spin dephasing in electron-doped monolayer MoS$_2$. Using time-resolved Kerr rotation spectroscopy and applied in-plane magnetic fields, a nanosecond-timescale Larmor spin precession signal commensurate with $g$-factor $|g_0|\simeq 1.86$ is observed in several different MoS$_2$ samples grown by chemical vapor deposition. The dephasing rate of this oscillatory signal increases linearly with magnetic field, suggesting that the coherence arises from a sub-ensemble of localized electron spins having an inhomogeneously-broadened distribution of $g$-factors, $g_0 + Δg$. In contrast to $g_0$, $Δg$ is sample-dependent and ranges from 0.042 to 0.115.

description: Despite the huge importance of friction in regulating movement in all natural and technological processes, the mechanisms underlying dissipation at a sliding contact are still a matter of debate. Attempts to explain the dependence of measured frictional losses at nanoscale contacts on the electronic degrees of freedom of the surrounding materials have so far been controversial. Here, it is proposed that friction can be explained by considering damping of stick-slip pulses in a sliding contact. Based on friction force microscopy studies of La$_{(1-x)}$Sr$_x$MnO$_3$ films at the ferromagnetic-metallic to paramagnetic-polaronic conductor phase transition, it is confirmed that the sliding contact generates thermally-activated slip pulses in the nanoscale contact, and argued that these are damped by direct coupling into phonon bath. Electron-phonon coupling leads to the formation of Jahn-Teller polarons and a clear increase in friction in the high temperature phase. There is no evidence for direct electronic drag on the atomic force microscope tip nor any indication of contributions from electrostatic forces. This intuitive scenario, that friction is governed by the damping of surface vibrational excitations, provides a basis for reconciling controversies in literature studies as well as suggesting possible tactics for controlling friction.

description: New Hispanic growth in North Cariolina brought challenging healthcare issues, especially to rural areas of NC. The purpose of this study was to collect baseline data pertaining to the oral health of Hispanics residing in Siler City, NC, a microcosm of the flourishing Latino growth found especially in the southeastern United States. A convenience sample of 158 Hispanic adults was recruited. A 41-item Spanish language survey was utilized. Multiple choice questions and Likert-type scales addressed preventive oral health practices, oral health knowledge and beliefs, perceived needs, and demographic information. Analyses, using SAS 9, were conducted to find demographic characteristics, frequencies, and correlations. The following associations were found statistically significant (p < .05): (1) brushing frequency and belief that healthy gums bleed; (2) dental insurance and frequency of dental visits; (3) source of oral hygiene instruction and participant's reported brushing or flossing, and dental visit frequency.

description: Coupling emitters with nanoresonators is an effective strategy to control light emission at the subwavelength scale with high efficiency. Low-loss dielectric nanoantennas hold particular promise for this purpose, owing to their strong Mie resonances. Herein, we explore a highly miniaturized platform for the control of emission based on individual subwavelength Si nanospheres (SiNSs) to modulate the directional excitation and exciton emission of two-dimensional transition metal dichalcogenides (2D TMDs). A modified Mie theory for dipole-sphere hybrid systems is derived to instruct the optimal design for desirable modulation performance. Controllable forward-to-backward intensity ratios are experimentally validated in 532 nm laser excitation and 635 nm exciton emission from a monolayer WS2. Versatile light emission control along all device orientations is achieved for different emitters and excitation wavelengths, benefiting from the facile size control and isotropic shape of SiNSs. Simultaneous modulation of excitation and emission via a single SiNS at visible wavelengths significantly improves the efficiency and directivity of TMD exciton emission and leads to the potential of multifunctional integrated photonics. Overall, our work opens promising opportunities for nanophotonics and polaritonic systems, enabling efficient manipulation, enhancement and reconfigurability of light-matter interactions.

description: The Smart grid (SG), generally known as the next-generation power grid emerged as a replacement for ill-suited power systems in the 21st century. It is in-tegrated with advanced communication and computing capabilities, thus it is ex-pected to enhance the reliability and the efficiency of energy distribution with minimum effects. With the massive infrastructure it holds and the underlying communication network in the system, it introduced a large volume of data that demands various techniques for proper analysis and decision making. Big data analytics, machine learning (ML), and deep learning (DL) plays a key role when it comes to the analysis of this massive amount of data and generation of valuable insights. This paper explores and surveys the Smart grid architectural elements, machine learning, and deep learning-based applications and approaches in the context of the Smart grid. In addition in terms of machine learning-based data an-alytics, this paper highlights the limitations of the current research and highlights future directions as well.

description: Using large-scale molecular dynamics simulations for a system of $10^6$ particles, the response of a dense amorphous solid to the continuous expansion of its volume is investigated. We find that the spatially uniform glassy state becomes unstable via the formation of cavities, which eventually leads to failure. By scanning through a wide range of densities and temperatures, we determine the state points at which the instability occurs and thereby provide estimates of the co-existence density of the resultant glass phase. Evidence for long-lived, inhomogeneous configurations with a negative pressure is found, where the frozen-in glass structure contains spherical cavities or a network of void space. Furthermore, we demonstrate the occurrence of hysteretic effects when the cavitated solid is compressed to regain the dense glassy state. As a result, a new glass state is obtained, the pressure of which is different from the initial one due to small density inhomogeneities that are generated by the dilation-compression cycle.

description: Over the last decade there has been increasing concern about the amount of time individuals spend online (Twenge et al. 2017, Orben 2020, Kozyreva et al. 2020). However, there has been very little research progress, even though public and policy attention have been high (e.g., The Social Dilemma documentary). While some have argued that this lack of progress is due to a lack in underlying theory (Granic et al. 2020, Orben 2020) others have argued that there is a dearth of good measurement (Parry et al. 2021), with most of the literature relying on sub-standard self-report questions about time spent online to gauge digital technology use and relate it to a variety of outcomes. The measurement issue has been mentioned for many years (Andrews et al., 2015, Vanden Abeele et al. 2013, Scharkow 2016), however there has been very little progress, with the necessary industry-academia collaborations still nascent or unsuccessful. In this study, we provide a proof-of-concept for how digital data derived directly from a company in the technology industry could be used to study the concerns around the time we spend online. In particular, we use diverse telemetry metrics from the Mozilla Firefox web browser to predict a user wanting to spend more or less time on the Internet (for measures, see Appendix 1). This investigation will help inform future research and theory about digital wellbeing and digital disconnection, as well as crucial industry-academia collaborations.

description: The generation and storage of entangled photons play important roles in quantum information technique. Spontaneous Raman scattering (SRS) in atomic ensembles provides a promising method to generate entangled photons capable of storage. In the past experiments, a spin-wave-photon entangled state is produced via SRS in an atomic ensemble, with which a pair of entangled photons is obtained. Here, we report a scheme of simultaneously generating two spin-wave-photon entangled states in an atomic ensemble by collecting Stokes photons at two different directions. Based on the obtained two atom-photon entangled sources, we generate a three-photon GHZ polarization-entangled state and conditionally prepare a polarization-entangled photon pair, respectively.

description: This document is Deliverable D3.2 “Human rights impact assessment (first version)” of the METICOS project.
 In the context of WP3, this Deliverable seeks to identify, evaluate and address the adverse effects on human rights emerging from the METICOS project, and in turn, prevent the METICOS components from breaching fundamental rights and/or negatively impacting socio-cultural factors.
 In order to achieve its aim, this Deliverable: identifies the scope of the Human Rights Impact Assessment (HRIA); identifies the impacted groups of persons and lists the possibly impacted human rights; evaluates the impacts of the METICOS platform on human rights; formulates mitigation measures; provides for an audit and review stage of the HRIA. The assessment process began at the inception of the project (M03) and will carry on throughout its lifetime (M36). During its process, it will analyse all stages of the development process of METICOS to gain an understanding of how each component has approached human rights intersectionality from every aspect of its development.
 It is important to note that, in line with the DoA, this Deliverable (D3.2) consists of a “first version of the report on human rights impact assessment”. By consequence, this Deliverable should be considered as an interim version. A second final version of the Human rights impact assessment will be submitted on M30.
