4-Year Radiographic & Esthetic Evaluation of Peri-Implant Tissue in Immediate Implants Replacing Single Teeth in the Esthetic Zone
Creators: name: Wang, Theresa C.
Publisher: name: University of North Carolina at Chapel Hill
Year: 2012

description: It is suggested that encroachment of the implant-abutment interface (IAI) to the existing tooth (< 1.5mm), negatively affects bone levels. As bone is the foundation for soft tissue, changes in bone levels may influence the overall esthetic outcome. The first part of this thesis details a study on 44 dental implants placed in 38 patients. Peri-apical radiographs and dental photographs were evaluated at 1 and 4 year/s to assess interproximal bone levels and pink esthetics. Current data assessed failed to indicate a relationship between IAI - tooth distances and bone changes at 4 years. Data suggest that there is no correlation between proximity of dental implant to adjacent tooth and interproximal soft tissue fill. Data also suggest that crestal bony changes following immediate dental implant placement do not have any relationship with soft tissue esthetics. Further investigations are necessary to examine soft and hard tissue architecture and their influence on esthetics. The second part of this paper consists of a comprehensive review discussing the multi-factorial nature of dental implant esthetics.
The Role of Digital Health in Managing Non-Communicable Diseases during COVID-19 Pandemic: A Scoping Review
Creators: name: Wei, Ting

Year: 2022
Subjects: subject: Medicine and Health Sciences

description: In the last few months, the ongoing outbreak of COVID-19 has significantly changed everyone’s life. Prevention measures have been taken by the government in order to stop the spread such as practicing social distancing, closure of school and non-essential business and closure of international and interstate borders. Healthcare system has been dramatically disrupted by the virus which adversely impact the care of people with non-communicable chronic diseases (NCDs). Reduced access to primary care combined with the fear of exposure to the virus led to a disruption in the care of NCDs patients. The pandemic has forced the implementation of digital health in managing NCDs patients, at the same time, recognising the importance of incorporating digital health into healthcare system. Evidence about how digital health is utilised during the pandemic is scarce, the aim of this review is to capture and summarize how digital health interventions support NCD management during COVID-19 by adapting the WHO framework – Classification of Digital Health Interventions V1.0; and how these digital health interventions contribute to health systems strengthening by applying WHO Six Building Blocks in order to improve health outcomes? In addition, to examine the effectiveness of digital health in delivering care to NCDs patients, and summarise what are the barriers and facilitators of digital health interventions in managing NCD during COVID-19.

description: Early results from the JWST-MIRI guaranteed time programs on protostars (JOYS) and disks (MINDS) are presented. Thanks to the increased sensitivity, spectral and spatial resolution of the MIRI spectrometer, the chemical inventory of the planet-forming zones in disks can be investigated with unprecedented detail across stellar mass range and age. Here data are presented for five disks, four around low-mass stars and one around a very young high-mass star. The mid-infrared spectra show some similarities but also significant diversity: some sources are rich in CO2, others in H2O or C2H2. In one disk around a very low-mass star, booming C2H2 emission provides evidence for a ``soot'' line at which carbon grains are eroded and sublimated, leading to a rich hydrocarbon chemistry in which even di-acetylene (C4H2) and benzene (C6H6) are detected (Tabone et al. 2023). Together, the data point to an active inner disk gas-phase chemistry that is closely linked to the physical structure (temperature, snowlines, presence of cavities and dust traps) of the entire disk and which may result in varying CO2/H2O abundances and high C/O ratios >1 in some cases. Ultimately, this diversity in disk chemistry will also be reflected in the diversity of the chemical composition of exoplanets.

description: Numerous applications in data mining and machine learning require recovering a matrix of minimal rank. Robust principal component analysis (RPCA) is a general framework for handling this kind of problems. Nuclear norm based convex surrogate of the rank function in RPCA is widely investigated. Under certain assumptions, it can recover the underlying true low rank matrix with high probability. However, those assumptions may not hold in real-world applications. Since the nuclear norm approximates the rank by adding all singular values together, which is essentially a $\ell_1$-norm of the singular values, the resulting approximation error is not trivial and thus the resulting matrix estimator can be significantly biased. To seek a closer approximation and to alleviate the above-mentioned limitations of the nuclear norm, we propose a nonconvex rank approximation. This approximation to the matrix rank is tighter than the nuclear norm. To solve the associated nonconvex minimization problem, we develop an efficient augmented Lagrange multiplier based optimization algorithm. Experimental results demonstrate that our method outperforms current state-of-the-art algorithms in both accuracy and efficiency.

description: Possible non-standard couplings which could contribute to the t -> b W process are studied based on the effective-Lagrangian approach. The corresponding effective Lagrangian consists of four kinds of dimension-6 effective operators, each of which has an independent coupling constant. In this analysis, all those couplings are treated as complex numbers and constraints on them are estimated by using recent experimental data from the LHC. We point out that the resultant constraints on those couplings are still not that strong because contributions from some couplings can work oppositely with each other.

description: Check-worthy claim detection aims at providing plausible misinformation to downstream fact-checking systems or human experts to check. This is a crucial step toward accelerating the fact-checking process. Many efforts have been put into how to identify check-worthy claims from a small scale of pre-collected claims, but how to efficiently detect check-worthy claims directly from a large-scale information source, such as Twitter, remains underexplored. To fill this gap, we introduce MythQA, a new multi-answer open-domain question answering(QA) task that involves contradictory stance mining for query-based large-scale check-worthy claim detection. The idea behind this is that contradictory claims are a strong indicator of misinformation that merits scrutiny by the appropriate authorities. To study this task, we construct TweetMythQA, an evaluation dataset containing 522 factoid multi-answer questions based on controversial topics. Each question is annotated with multiple answers. Moreover, we collect relevant tweets for each distinct answer, then classify them into three categories: "Supporting", "Refuting", and "Neutral". In total, we annotated 5.3K tweets. Contradictory evidence is collected for all answers in the dataset. Finally, we present a baseline system for MythQA and evaluate existing NLP models for each system component using the TweetMythQA dataset. We provide initial benchmarks and identify key challenges for future models to improve upon. Code and data are available at: https://github.com/TonyBY/Myth-QA

description: Background:: Data on outcome of children undergoing in-hospital cardiopulmonary resuscitation (CPR) in low- and middle-income countries are scarce. Aims:: To describe the clinical profile and outcome of children undergoing in-hospital CPR. Methods:: This prospective observational study was undertaken in the Advanced Pediatric Center, PGIMER, Chandigarh. All patients aged 1 month to 12 years who underwent in-hospital CPR between July 2010 and March 2011 were included. Data were recorded using the ‘Utstein style’. Outcome variables included ‘sustained return of spontaneous circulation’ (ROSC), survival at discharge and neurological outcome at 1 year. Results:: The incidence of in-hospital CPR in all hospital admissions (n = 4654) was 6.7% (n = 314). 64.6% (n = 203) achieved ROSC, 14% (n = 44) survived to hospital discharge and 11.1% (n = 35) survived at 1 year. Three-quarters of survivors had a good neurological outcome at 1-year follow-up. Sixty per cent of patients were malnourished. The Median Pediatric Risk of Mortality-III (PRISM-III) score was 16 (IQR 9–25). Sepsis (71%), respiratory (39.5%) and neurological (31.5%) illness were the most common diagnoses. The most common initial arrhythmia was bradycardia (52.2%). On multivariate logistic regression, duration of CPR, diagnosis of sepsis and requirement for vasoactive support prior to arrest were independent predictors of decreased hospital survival. Conclusions:: The requirement for in-hospital CPR is common in PGIMER. ROSC was achieved in two-thirds of children, but mortality was higher than in high-income countries because of delayed presentation, malnutrition and severity of illness. CPR >15 min was associated with death. Survivors had good long-term neurological outcome, demonstrating the value of timely CPR.

description: In this paper, we present a novel method for detecting fake and Large Language Model (LLM)-generated profiles in the LinkedIn Online Social Network immediately upon registration and before establishing connections. Early fake profile identification is crucial to maintaining the platform's integrity since it prevents imposters from acquiring the private and sensitive information of legitimate users and from gaining an opportunity to increase their credibility for future phishing and scamming activities. This work uses textual information provided in LinkedIn profiles and introduces the Section and Subsection Tag Embedding (SSTE) method to enhance the discriminative characteristics of these data for distinguishing between legitimate profiles and those created by imposters manually or by using an LLM. Additionally, the dearth of a large publicly available LinkedIn dataset motivated us to collect 3600 LinkedIn profiles for our research. We will release our dataset publicly for research purposes. This is, to the best of our knowledge, the first large publicly available LinkedIn dataset for fake LinkedIn account detection. Within our paradigm, we assess static and contextualized word embeddings, including GloVe, Flair, BERT, and RoBERTa. We show that the suggested method can distinguish between legitimate and fake profiles with an accuracy of about 95% across all word embeddings. In addition, we show that SSTE has a promising accuracy for identifying LLM-generated profiles, despite the fact that no LLM-generated profiles were employed during the training phase, and can achieve an accuracy of approximately 90% when only 20 LLM-generated profiles are added to the training set. It is a significant finding since the proliferation of several LLMs in the near future makes it extremely challenging to design a single system that can identify profiles created with various LLMs.

description: In this paper, we present a quantum-key-distribution (QKD)-based quantum private query (QPQ) protocol utilizing single-photon signal of multiple optical pulses. It maintains the advantages of the QKD-based QPQ, i.e., easy to implement and loss tolerant. In addition, different from the situations in the previous QKD-based QPQ protocols, in our protocol, the number of the items an honest user will obtain is always one and the failure probability is always zero. This characteristic not only improves the stability (in the sense that, ignoring the noise and the attack, the protocol would always succeed), but also benefits the privacy of the database (since the database will no more reveal additional secrets to the honest users). Furthermore, for the user's privacy, the proposed protocol is cheat sensitive, and for security of the database, we obtain an upper bound for the leaked information of the database in theory.

The meaning of "anomalous weak values" in quantum and classical theories
Creators: name: Sokolovski, D.
Publisher: name: arXiv
Year: 2015
Subjects: subject: Quantum Physics (quant-ph)
subject: FOS: Physical sciences

description: The readings of a highly inaccurate "weak" quantum meter, employed to determine the value of a dichotomous variable $S$ without destroying the interference between the alternatives,may take arbitrary values. We show that the expected values of its readings may take any real value, depending on the the choice of the states in which the system is pre- and post-selected. Some of these values must fall outside the range of eigenvalues of $A$, in which case they may be expressed as "anomalous" averages obtained with negative probability weights, constructed from available probability amplitudes. This behaviour is a natural consequence of the Uncertainty Principle. The phenomenon of "anomalous weak values" has no non-trivial analogue in classical statistics.

We show how one could spectroscopically address the fractional charged excitations inspecting separately their charge and scaling dimensions. We thus compare the behaviour of the Pfaffian and the anti-Pfaffian non-Abelian edge states models in order to give possible experimental signatures to identify the appropriate model for this fractional quantum Hall states. Finally we investigate how the temperature of the LC resonant circuit can be used in order to enhance the sensibility of the measurement scheme.

Creators: name: Bergquist, Ronald E.
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2006

description: Large, urban institutions are well represented in American public library history, but the stories of libraries in small towns or in rural areas are not as well represented. During the twentieth century, local citizens in six small Moore County, North Carolina towns ("small" here defined as towns having less than five thousand residents) established and maintained local public libraries. Some of the libraries failed over time, some succeeded, but all of them went through a process of finding their place in their community and governmental environments, environments that were themselves changing with the times. Using newspaper articles, augmented with interviews and direct observation, this is a study of those libraries and the people who created them - in the context of their times and circumstances, and in the context of how they were and are viewed by the profession of librarianship.

Social policy in South America: the effect of organized labor and civil society groups on pension and health reforms in Argentina and Brazil (1988-2008)
Creators: name: Niedzwiecki, Sara

description: The present paper examines the effect of unions and other civil society groups on social policy in South American democracies. Long-term effect of such organized groups will be measured through levels of social expenditure; and contextualized influence will be measured observing the process of structural reforms (or lack thereof) in Argentina and Brazil in the health and pension sectors. This analysis shows that both partisanship and union strength matter in the expansion period for social security spending and pension reform processes. Alternatively, in determining spending on human capital and health reforms, the role of organized labor and other social groups is the key variable to understand social policy change. This study seeks to improve upon previous work by testing whether welfare state theories travel to South America to explain differences in the depth of social policy changes. Additionally, it innovates by assessing the independent effect of unions on social policy since the return of democracy to the present and by combining quantitative and qualitative research strategies, namely a modified random effects pooled time series and a case study comparison.

description: Despite the critical importance of Digital Transformation, up to 95% of initiatives fail to deliver expected business benefits. This paper explores the role of Business Architecture practices in enhancing digital transformation success. Using an adapted Balanced Scorecard approach and a Structural Equation Model (SEM), we analysed survey responses from 129 industry practitioners using a Partial Least Squares (PLS) approach. Our findings indicate that effective business architecture practices significantly improve business alignment, efficiency, service delivery, and strategic outcomes, leading to successful digital transformation. The study also validates factors proposed by AL-Malaise AL-Ghamdi (2017) in the context of digital transformation. The paper presents an adapted conceptual model addressing discriminant validity issues in previous models and benefiting from the robustness of the Balanced Scorecard approach. The study concludes by highlighting the essential role of business architecture in driving digital transformation success.

description: Quasicrystal (QC) has no periodicity but has a unique rotational symmetry forbidden in periodic crystals. Lack of microscopic theory of the crystalline electric field (CEF) in the QC and approximant crystal (AC) has prevented us from understanding the electric property, especially the magnetism. By developing the general formulation of the CEF in the rare-earth based QC and AC, we have analyzed the CEF in the QC Au-SM-Tb and AC (SM=Si, Ge, and Ga). The magnetic anisotropy arising from the CEF plays an important role in realizing unique magnetic states on the icosahedron (IC). By constructing the minimal model with the magnetic anisotropy, we have analyzed the ground-state properties of the IC, 1/1 AC, and QC. The hedgehog state is characterized by the topological charge of one and the whirling-moment state is characterized by the topological charge of three. The uniform arrangement of the ferrimagnetic state is stabilized in the QC with the ferromagnetic (FM) interaction, which is a candidate for the magnetic structure recently observed FM long-range order in the QC Au-Ga-Tb. The uniform arrangement of the hedgehog state is stabilized in the QC with the antiferromagnetic interaction, which suggests the possibility of the topological magnetic long-range order.

description: Ultraluminous supersoft sources (ULSs) are defined by a thermal spectrum with colour temperatures ~0.1 keV, bolometric luminosities ~ a few 10^39 erg/s, and almost no emission above 1 keV. It has never been clear how they fit into the general scheme of accreting compact objects. To address this problem, we studied a sample of seven ULSs with extensive Chandra and XMM-Newton coverage. We find an anticorrelation between fitted temperatures and radii of the thermal emitter, and no correlation between bolometric luminosity and radius or temperature. We compare the physical parameters of ULSs with those of classical supersoft sources, thought to be surface-nuclear-burning white dwarfs, and of ultraluminous X-ray sources (ULXs), thought to be super-Eddington stellar-mass black holes. We argue that ULSs are the sub-class of ULXs seen through the densest wind, perhaps an extension of the soft-ultraluminous regime. We suggest that in ULSs, the massive disk outflow becomes effectively optically thick and forms a large photosphere, shrouding the inner regions from our view. Our model predicts that when the photosphere expands to >10,000 km and the temperature decreases below approximately 50 eV, ULSs become brighter in the far-UV but undetectable in X-rays. Conversely, we find that harder emission components begin to appear in ULSs when the fitted size of the thermal emitter is smallest (interpreted as a shrinking of the photosphere). The observed short-term variability and absorption edges are also consistent with clumpy outflows. We suggest that the transition between ULXs (with a harder tail) and ULSs (with only a soft thermal component) occurs at blackbody temperatures of approximately 150 eV.

description: The effect of isoscalar S-wave processes $ππ\toππ,K\overline{K},ηη$ is considered in the analysis of data (from the ARGUS, CLEO, CUSB, Crystal Ball, Belle, BABAR collaborations) on the bottomonia decays --- $Υ(mS)\toΥ(nS)ππ$ ($m>n, m=2,3,4,5, n=1,2,3$). It is shown that the dipion mass spectra of these decays are explained by the unified mechanism related to the contribution of the multichannel $ππ$ scattering in the final states of these reactions. Since in the analysis the multichannel $ππ$-scattering amplitudes did not change in comparison with the ones in our combined analysis of data on the multichannel $ππ$ scattering and on the charmonia decays --- $J/ψ\toϕ(ππ, K\overline{K})$ and $ψ(2S)\to J/ψ(ππ)$ (from the Crystal Ball, DM2, Mark II, Mark III, and BES II) --- the results confirm all our earlier conclusions on the scalar mesons.

description: We present a detailed analysis of the Horizontal Branch of the Carina Dwarf Spheroidal Galaxy by means of synthetic modelling techniques, taking consistently into account the star formation history and metallicity evolution as determined from main sequence and red giant branch spectroscopic observations. We found that a range of integrated red giant branch mass loss values of 0.1-0.14 M, increasing with metallicity, is able to reproduce the colour extension of the old Horizontal Branch. However, leaving the mass loss as the only free parameter is not enough to match the detailed morphology of Carina Horizontal Branch. We explored the role played by the star formation history on the discrepancies between synthetic and observed Horizontal Branches. We derived a toy bursty star formation history that reproduces the horizontal branch star counts, and also matches qualitatively the red giant and the turn off regions. This star formation history is made of a subset of age and [M/H] components of the star formation history based on turn off and red giants only, and entails four separate bursts of star formation of different strenghts, centred at 2, 5, 8.6 and 11.5 Gyr, with mean [M/H] decreasing from \sim -1.7 to \sim -2.2 for increasing ages, and a Gaussian spread of 0.1 dex. The comparison between the metallicity distribution function of our star formation history and the one measured from the infrared CaT feature using a CaT-[Fe/H] calibration shows a qualitative agreement, once taken into account the range of [Ca/Fe] abundances measured in a sample of Carina stars, that biases the derived [Fe/H] distribution toward too low values. In conclusion, we have shown how the information contained within the horizontal branch of Carina (and dwarf galaxies in general) can be extracted and interpreted to refine the star formation history derived from red giants and turn off stars only.

description: Community-based afterschool programs are valuable spaces for researchers to codesign technologies with direct relevance to local communities. However, afterschool programs differ in resources available, culture, and student demographics in ways that may impact the efficacy of the codesign process and outcome. We ran a series of multi-week educational game codesign workshops across five programs over twenty weeks and found notable differences, despite deploying the same protocol. Our findings characterize three types of programs: Safe Havens, Recreation Centers, and Homework Helpers. We note major differences in students' patterns of participation directly influenced by each program's culture and expectations for equitable partnerships and introduce Comparative Design-Based Research (cDBR) as a beneficial lens for codesign.
