description: Sterotactic radiosurgery is becoming an integral modality in the management of intracranial meningiomas, both as the primary treatment or as adjuvant therapy. This study analyzes the scholarly impact of the top 100 cited articles on the stereotactic radiosurgical management of intracranial meningiomas. A ranked list of the 100 most-cited articles was generated using the Scopus database by searching the keywords ‘intracranial meningioma’ and ‘stereotactic radiosurgery’. All articles were then evaluated on multiple criteria regarding both the publication of the articles (year of publication, journal, country of origin, and authors) as well as their methods and foci (type of study, location of studied meningiomas, and type of radiosurgical modality). Quantitaitve and qualitative analyses were then performed from the collected data. The most frequently cited articles on stereotactic radiosurgical management of intracranial meningiomas were published between 1990 and 2016. The average citation-per-year across all papers in the list was 6.1. The most studied anatomic area of intracranial meningiomas was the skull base, with the cavernous sinus being the most well-studied specific site. The most utilized stereotactic radiosurgical modality was Gamma Knife radiosurgery. The country with the highest number of publications was the United States. Twenty-six percent of the articles were published in the journal Neurosurgery; Lunsford, Kondziolka, Flickinger, Sheehan, and Pollock were respectively the most frequent listed authors among this list. The most active academic institute publishing on this topic was the University of Pittsburgh Medical Center. Stereotactic radiosurgery is an integral modality in the management of intracranial meningiomas. This bibliometric analysis sheds the light on the ways in which intracranial meningiomas have been studied in the past two decades in order to identify trends among neurosurgeons and radiation oncologists and to reveal areas of rising and declining focus.

description: We study the spectrum of the hydrogen atom in Snyder space in a semiclassical approximation based on a generalization of the Born-Sommerfeld quantization rule. While the corrections to the standard quantum mechanical spectrum arise at first order in the Snyder parameter for the $l=0$ states, they are of second order for $l\neq 0$. This can be understood as due to the different topology of the regions of integration in phase space.

description: Primary paragangliomas (PGs) are extra-adrenal neuroendocrine tumours that are extremely rare. Multiple lesions in the central nervous system raise suspicion of a metastatic process. Lack of consensus on their management warrants the categorization of existing literature to evaluate management options. A systematic review of the medical literature on paraganglioma within the cranial vault was completed in accordance with PRISMA guidelines using the Medline database. Tumour physical measures, management parameters, and immunohistochemistry of all documented cases of primary and secondary paraganglioma within the cranial vault were descriptively compared. This review was augmented by comparison with our centre’s case of a 48-year-old man diagnosed with metastatic PG originating in the cauda equina and seeding in the cerebellum. Histological parameters within the literature was also established. The systematic literature review yielded published 52 papers. Most prevalent primary intracranial PGs (n = 37) were in the sellar region (78%, n = 23) and the cerebellum (21%, n = 6). The highest progression free survival was seen in primary sellar PGs (87.5% by 34.5 months) and cerebellar PGs (100% by 35.7 months) when treated with adjuvant radiotherapy with subtotal resection or gross total resection, respectively. Contrasting, the most frequent intracranial PGs metastases (n = 15) occurred in the cerebellum (36%, n = 6), and the cerebral parenchyma (29%, n = 4). Their recurrence rate was between 4 and 10% and these metastasized PG in the cerebellum are slow growing (8.9 years, range: 3–22 years). Adjuvant radiotherapy with Gross Total Resection resulted in the optimum progression-free survival (100% up to 48 months) for the patient with PGs metastasis to the cerebellum. Metastatic PGs tend to be slow-growing and are clinically silent tumours. Diagnosed patients should undergo regular surveillance neuroradiological assessment, regardless of symptomatology, for metastases along the complete neural axis. We recommend operative management with GTR and adjunct RT in these patients.

description: An increasing number of public libraries pursue external funding to supplement operating income received from state and municipal funds. To compete with other social causes and to make fundraising efforts worthwhile, public libraries must be strategic. This study examines the efforts of the Queens Borough Public Library to seek out grants from external funding sources. A content analysis of major New York newspapers examined the publicity surrounding library programs and services to determine if increased media attention attracted new contributions. While the marketing efforts of the library appear to be successful, the library must employ a greater strategy to signal future donors.

description: The U.S. Department of Health and Human Services defines health literacy as "the degree to which individuals have the capacity to obtain, process, and understand basic health information and services needed to make appropriate health decisions".  One of the antecedents of health literacy, patient empowerment, has seen an increase from the participation of patients in online health communities.  In this study, 4367 group forum posts from 215 users of Anxiety Connect, a moderated online health community, were analyzed using the patient empowerment processes and outcomes of Bartlett and Coulson.  Patient empowerment was evident in the forum posts.  Every post contained evidence of at least one empowerment process; X% of the posts contained evidence of at least one empowerment outcome. The empowerment process most prominent in the Anxiety Connect forum was sharing experiences, included in 57.6% of Total Posts.  The empowerment outcome most prominent was increased acceptance, included in 5.1% of Total Posts, closely followed by optimism and hope for the future and increased social well-being, included int 4.5% and 4.7% of the Total Posts respectively. These findings have implications for the design of moderated online health communities.

description: We study distributional robustness in the context of Extreme Value Theory (EVT). We provide a data-driven method for estimating extreme quantiles in a manner that is robust against incorrect model assumptions underlying the application of the standard Extremal Types Theorem. Typical studies in distributional robustness involve computing worst case estimates over a model uncertainty region expressed in terms of the Kullback-Leibler discrepancy. We go beyond standard distributional robustness in that we investigate different forms of discrepancies, and prove rigorous results which are helpful for understanding the role of a putative model uncertainty region in the context of extreme quantile estimation. Finally, we illustrate our data-driven method in various settings, including examples showing how standard EVT can significantly underestimate quantiles of interest.
Signatures of the Current Blockade Instability in Suspended Carbon Nanotubes

description: Transport measurements allow sensitive detection of nanomechanical motion of suspended carbon nanotubes. It has been predicted that when the electro-mechanical coupling is sufficiently large a bistability with a current blockade appears. Unambiguous observation of this transition by current measurements may be difficult. Instead, we investigate the mechanical response of the system, namely the displacement spectral function; the linear response to a driving; and the ring-down behavior. We find that by increasing the electro-mechanical coupling the peak in the spectral function broadens and shifts at low frequencies while the oscillator dephasing time shortens. These effects are maximum at the transition where non-linearities dominate the dynamics. These strong signatures open the way to detect the blockade transition in devices currently studied by several groups.

description: This study explores whether the combination of a structured wiki and a tagging vocabulary create a more effective digital collaborative space than email communication, for both current collaboration needs and the retrieval of past collaboration information. To test this, I added a predefined tagging vocabulary and collaboration nodes to the North Carolina Area Health Education Centers' underused wiki. The methods involved tracking the NC AHEC team's email and wiki communication for two months after implementation of the redesigned wiki and comparing this data to retroactively collected use of wiki and email for ten months prior to implementation. The study also included surveys before and after the study, addressing subjects' attitudes towards wikis and tagging.  The subjects' overall use of both communication tools decreased, but due to several potential factors, the cause could not be determined. The study results were inconclusive.

description: This study evaluates the quality of reference transactions in academic music libraries. The study builds on previous research that identified music libraries as having different evaluation needs than main, multidisciplinary academic libraries. Using unobtrusive evaluation techniques, this study analyzes chat/IM and e-mail reference transactions at 128 U.S. academic music libraries in order to determine the quality of responses provided. Differences in quality of responses between the two mediums are also analyzed. The results of this study provide a state-of-the-art view of the current media on which reference services are offered for music libraries, and the quality of those services. This work discusses the implications of the findings and provides suggestions for improving the quality of these reference services in academic music libraries.

description: The connection between black hole thermodynamics and chemistry is extended to the lower-dimensional regime by considering the rotating and charged BTZ metric in the $(2+1)$-D and a $(1+1)$-D limits of Einstein gravity. The Smarr relation is naturally upheld in both BTZ cases, where those with $Q \ne 0$ violate the Reverse Isoperimetric Inequality and are thus superentropic. The inequality can be maintained, however, with the addition of a new thermodynamic work term associated with the mass renormalization scale. The $D\rightarrow 0$ limit of a generic $D+2$-dimensional Einstein gravity theory is also considered to derive the Smarr and Komar relations, although the opposite sign definitions of the cosmological constant and thermodynamic pressure from the $D>2$ cases must be adopted in order to satisfy the relation. The requirement of positive entropy implies a lower bound on the mass of a $(1+1)$-D black hole. Promoting an associated constant of integration to a thermodynamic variable allows one to define a "rotation" in one spatial dimension. Neither the $D=3$ nor the $D \rightarrow 2$ black holes exhibit any interesting phase behaviour.

ULX behaviour: the ultraluminous state, winds & interesting anomalies

description: Recent evidence - in particular the hard X-ray spectra obtained by NuSTAR, and the large amplitude hard X-ray variability observed when ultraluminous X-ray sources (ULXs) show soft spectra - reveals that common ULX behaviour is inconsistent with known sub-Eddington accretion modes, as would be expected for an intermediate-mass black hole (IMBH). Instead, it appears that the majority of ULXs are powered by super-Eddington accretion onto stellar-mass black holes. Here, we will review work that delves deeper into ULX spectral-timing behaviour, demonstrating it remains consistent with the expectations of super-Eddington accretion. One critical missing piece from this picture is the direct detection of the massive, radiatively-driven winds expected from ULXs as atomic emission/absorption line features in ULX spectra; we will show it is very likely these have already been detected as residuals in the soft X-ray spectra of ULXs. Finally, we will discuss ULXs that do not appear to conform to the emerging ULX behaviour patterns. In particular we discuss the implications of the identification of a good IMBH candidate as a background QSO; and the confirmation of an IMBH/ULX candidate in the galaxy NGC 2276 via the radio/X-ray fundamental plane.

description: This study is concerned with exploring how small manufacturers in North Carolina currently market their products and capabilities as well as their perception of social media in order to determine if social media could be a useful marketing strategy.  Interviews were conducted with 7 manufacturers, three of whom current use or are in the process of implementing social media.  Findings indicate that the manufacturers using social media have achieved marketing successes and that there is great interest from all of the manufacturers in how social media could be applied to their business with the primary barrier to adoption being the business owner.  Recommendations on how manufacturers can begin to implement social media are suggested.
title: A variation on the firefighter problem on graphs
Creators: name: Marcoux, John
Publisher: name: Memorial University of Newfoundland
Year: 2022

description: In the classic version of the game of Firefighter, on the first turn a fire breaks out on a vertex in a graph G and then k firefighters protect k vertices. On each subsequent turn, the fire spreads to the collective unburnt neighbourhood of all the burning vertices and the firefighters again protect k vertices. Once a vertex has been burnt or protected it remains that way for the rest of the game. A common objective with respect to some infinite graph G is to determine how many firefighters are necessary to stop the fire from spreading after a finite number of turns, commonly referred to as containing the fire. We introduce the concept of distance-restricted firefighting where the firefighters’ movement is restricted so they can only move up to some fixed distance d per turn rather than being able to move without restriction. We establish some general properties of this new game in contrast to properties of the original game, and we investigate specific cases of the distance-restricted game on the infinite strong, hexagonal, and square grids. We conjecture that two firefighters are insufficient on the square grid when d =2, and we pose some questions about how many firefighters are required in general when d = 1.

description: This paper discusses the creation of databases specially designed for pediatric drugs. There are many medical drugs databases available currently for adults but there is no database for pediatric drugs that can benefit end users who are looking for information specific to drugs for children. So the Division of Pediatric Hematology Oncology in UNC, Chapel Hill wants to have a repository to store and organize information about pediatric drugs in order to provide this information in a structured and easily accessible format that will benefit end users. This database will also be used to provide information to end-users especially consumers about drug repurposing i.e. using the same pediatric drug for more than one purpose.

description: Dieser Artikel beschäftigt sich mit den Verteilungswirkungen der Reformen des österreichischen Lohnsteuer- und Sozialversicherungsbeitragssystems. Untersucht werden dazu Maßnahmen der Reformen 2004/05, 2009 und 2015/16. Im Mittelpunkt der Analyse stehen dabei die Auswirkungen von Veränderungen der staatlichen Einnahmenseite auf die Verteilung der Sekundäreinkommen. Während bei den meisten Untersuchungen Aspekte der vertikalen Verteilung im Vordergrund stehen, wird in dieser Arbeit ein spezieller Fokus auf den Einfluss der Reformen auf die Verteilung zwischen den Geschlechtern gelegt. Generell lässt sich feststellen, dass die betrachteten Reformen durchaus die größten relativen Einkommenszuwächse in den unteren Einkommensbereichen und somit bei Frauen mit sich bringen, durch aber gleichzeitig ständige Entlastung der oberen Einkommen und der besonderen Konzentration der Männereinkommen im oberen Einkommensbereich, Männer in wesentlich größerem Umfang von den Maßnahmen der einzelnen Reformen profitieren. Eine Analyse des Einflusses der Begünstigungen zeigt zudem, dass die Maßnahmen der untersuchten Reformen zu einer Umverteilung der Einkommen von Frauen zu Männern beitragen sowie von den verschiedenen Reformen eher Beschäftigte in Wirtschaftsklassen profitieren, die einen höheren Männeranteil aufweisen.

Complementing the results of the analytical studies, algorithm simulations and experimental demonstrations reported in detail in the deliverables of WP2, WP3, WP4 and WP5, the results presented in this deliverable are addressing particular features of each one of the 3 ARIADNE usage scenarios, such as blockage, misalignment, channel modelling and fitting to measured data, weather conditions impact (e.g. rain), mobility and adhoc connectivity. This deliverable is also aimed at sharing lessons learnt from the design, development and implementation of the 3 ARIADNE demonstrations. In that way, critical success factors, technology gaps and research challenges associated with the adoption and realization of the 3 ARIADNE pillars can be identified and promising research directions can be determined.

description: We describe the development and in-class evaluation of a Quantum Interactive Learning Tutorial (QuILT) on quantum key distribution, a context which involves an exciting application of quantum mechanics. The protocol used in the QuILT described here uses single photons with non-orthogonal polarization states to generate a random shared key over a public channel for encrypting and decrypting information. The QuILT strives to help upper-level undergraduate students learn quantum mechanics using a simple two state system. It actively engages students in the learning process and helps them build links between the formalism and the conceptual aspects of quantum physics without compromising the technical content. The in-class evaluation suggests that the validated QuILT is helpful in improving students' understanding of relevant concepts.

description: We propose a way to simulate mesoscopic transport processes with counter-propagating wavepackets of ultracold atoms in quasi one-dimensional (1D) waveguides, and show quantitative agreement with analytical results. The method allows the study of a broad range of transport processes at the level of individual modes, not possible in electronic systems. Typically suppressed effects of quantum coherence become manifest, along with the effects of tunable interactions, which can be used to develop a simpler type of sensitive atom interferometer.

description: Modern video players employ complex algorithms to adapt the bitrate of the video that is shown to the user. Bitrate adaptation requires a tradeoff between reducing the probability that the video freezes (rebuffers) and enhancing the quality of the video. A bitrate that is too high leads to frequent rebuffering, while a bitrate that is too low leads to poor video quality. Video providers segment videos into short segments and encode each segment at multiple bitrates. The video player adaptively chooses the bitrate of each segment to download, possibly choosing different bitrates for successive segments. We formulate bitrate adaptation as a utility-maximization problem and devise an online control algorithm called BOLA that uses Lyapunov optimization to minimize rebuffering and maximize video quality. We prove that BOLA achieves a time-average utility that is within an additive term O(1/V) of the optimal value, for a control parameter V related to the video buffer size. Further, unlike prior work, BOLA does not require prediction of available network bandwidth. We empirically validate BOLA in a simulated network environment using a collection of network traces. We show that BOLA achieves near-optimal utility and in many cases significantly higher utility than current state-of-the-art algorithms. Our work has immediate impact on real-world video players and for the evolving DASH standard for video transmission. We also implemented an updated version of BOLA that is now part of the standard reference player dash.js and is used in production by several video providers such as Akamai, BBC, CBS, and Orange.

description: We have developed a compact Compton gamma-ray imager with a large field of view and a low channel-count that is capable of quickly localizing gamma-ray sources in the few hundred keV - several MeV range. The two detector planes (scatter and absorber) employ bars of NaI(Tl) read out by photomultiplier tubes (PMTs) located at each end. The long-range imaging performance has been tested from 392 keV to 1274 keV. An angular resolution measure of 2.72 +/- 0.06 degrees and an efficiency of (1.79 +/- 0.04) x 10^(-3) at 662 keV is obtained. A Cs-137 (662 keV) source equivalent to a 10 mCi source 40 m away can be located in 60 seconds with an uncertainty of about a degree. No significant degradation in imaging performance is observed for source angles up to 40 degrees off axis.
Fractional Quantum Hall Effects in HgTe Quantum Wells
Creators: name: Wang, Jianhui

Year: 2015
Subjects: subject: Strongly Correlated Electrons (cond-mat.str-el)
subject: FOS: Physical sciences

description: We study the possibility of fractional quantum Hall effects in HgTe quantum wells using exact diagonalization. Our results show that Laughlin states, the Moore-Read state, and the Read-Rezayi $Z_3$ state can all be supported. However, near the level crossing point (of the single-particle spectrum), the gap can be destroyed by Landau level mixing, and the Moore-Read state and the Read-Rezayi state dominate over their respective competing states only for wide wells. For smaller well widths the Moore-Read state crosses over to the composite fermion Fermi sea, while the Read-Rezayi state loses its dominance over the hierarchy state.
description: The main changes are that Landau level mixing destroys the fractional quantum Hall effect near the level crossing point, and that the Moore-Read state and the Read-Rezayi state are favoured only for sufficiently wide quantum wells (caused by a mistake in some of the interaction matrix elements). 8 pages, 8 figures
Evaluating the Readability of Online Consumer Health Information Regarding Macular Degeneration

Macular degeneration

description: As consumers search for an increasing amount of health information online, it is important for the information that they find to not only be accurate, but written in an appropriate and accessible level of readability. Eight consumer health information websites were selected and a portion of text from each on the topic of macular degeneration, an eye disease that affects many older Americans and can result in the loss of central vision, was evaluated. The readability of the text was calculated using two tests: the Flesch-Kincaid Grade Level Index and the Flesch Reading Ease test. These calculations confirmed expectations that online consumer health information for macular degeneration is incomprehensible for a sizeable segment of the American population.
According to the results, this information is written on average at a reading level of nearly the eleventh grade.
A Case Study in System Migration to Linux in a Development and Production Environment

description: This case study describes the process the planning, the implementation, the testing, the migration, and the evaluation that took place in the migration of the main departmental server for the School of Information and Library Science at the University of North Carolina at Chapel Hill. This system is responsible for departmental mail and web services, as well as functioning as a developmental and research system for the faculty, staff, and students within the school's programs. The paper discusses the process of migration, from evaluating the new architecture to the final testing and modification following the implementation of the new system. The migration was from Sun Solaris on Sparc hardware to Linux running on Intel. The migration migrated 86 Gb worth of data and 800 users with at most 25 minutes of downtime for the critical applications.
On the Broadcast Capacity of Large Wireless Networks at Low SNR
Creators: name: Haddad, Serj

subject: FOS: Computer and information sciences

description: The present paper focuses on the problem of broadcasting information in the most efficient manner in a large two-dimensional ad hoc wireless network at low SNR and under line-of-sight propagation. A new communication scheme is proposed, where source nodes first broadcast their data to the entire network, despite the lack of sufficient available power. The signal's power is then reinforced via successive back-and-forth beamforming transmissions between different groups of nodes in the network, so that all nodes are able to decode the transmitted information at the end. This scheme is shown to achieve asymptotically the broadcast capacity of the network, which is expressed in terms of the largest singular value of the matrix of fading coefficients between the nodes in the network. A detailed mathematical analysis is then presented to evaluate the asymptotic behavior of this largest singular value.

description: The open source software community represents a new community of practice and approach to software development and distribution.  It is important to study this community because their approach differs radically from the traditional development and distribution of proprietary software.  One of the largest groups in the open source software community is the Linux operating systems community.  The community of users of the Linux operating system is a widespread group that frequently communicates through on-line newsgroups.  These newsgroups serve as forums where the members may participate in ongoing discussion, or "threads," reading other members' messages and posting messages of their own.  The participants can discuss issues relative to the Linux operating system, ask questions, provide technical support, and generally engage in the same activities that a face-to-face discussion group would engage in.  To increase our understanding of the Linux community, this study seeks to characterize the Linux community of practice through an analysis of these newsgroups.  While quantitative studies of this community performed, there has not been much work done in the way of qualitative studies.  The analysis is performed using categories developed by Bales' Interaction Process Analysis.  After determining the newsgroups that we wanted to analyze, selecting specific discussions from these newsgroups, and coding the messages using Bales' categories of Interaction Process Analysis, we were able to establish a clear picture of the frequency with which specific behaviors occurred in the newsgroups.   We found that in general most of the behaviors that occurred in the messages posted to the newsgroups were attempted answers, and the second most frequently occurring behaviors in the messages were questions.  There were a relatively small number of messages that displayed socio-emotional behavior.
Toward a More Effective Online Library Tutorial: An Experimental Study of UNC Libraries' Introduction to Library Research Tutorial

Questionnaires--Library user satisfaction

description: Due to increased Internet access and the prevalence of distance education, online instruction is increasing, and libraries generate a great deal of online library instruction content to meet the needs of users. This study investigates the UNC University Libraries' Introduction to Library Research tutorial in an effort to evaluate the tutorial and gather evidence to guide future updates. Twenty-four undergraduate students filled out a pre-test questionnaire, completed the tutorial, and answered a post-test questionnaire and an engagement questionnaire. While the average number of correct answers slightly increased in the post-test, the result was not statistically significant. The engagement questionnaire revealed that a recent design update was well-received and that while students do not necessarily consider the tutorial "fun," they would recommend it to others. This experimental approach provides evidence of student engagement with the online tutorial, serves as a possible model for evaluating the tutorial in the future, and provides benchmark data on which to compare future findings.
