description: Kelly (2007, hereafter K07) described an efficient algorithm, using Gibbs sampling, for performing linear regression in the fairly general case where non-zero measurement errors exist for both the covariates and response variables, where these measurements may be correlated (for the same data point), where the response variable is affected by intrinsic scatter in addition to measurement error, and where the prior distribution of covariates is modeled by a flexible mixture of Gaussians rather than assumed to be uniform. Here I extend the K07 algorithm in two ways. First, the procedure is generalized to the case of multiple response variables. Second, I describe how to model the prior distribution of covariates using a Dirichlet process, which can be thought of as a Gaussian mixture where the number of mixture components is learned from the data. I present an example of multivariate regression using the extended algorithm, namely fitting scaling relations of the gas mass, temperature, and luminosity of dynamically relaxed galaxy clusters as a function of their mass and redshift. An implementation of the Gibbs sampler in the R language, called LRGS, is provided.

Information services--Evaluation

description: Since the advent of the Internet, the concept of the "Digital Divide," has been at the forefront of governmental policy discussions. The current president and his administration have made huge strides in working to help Americans gain access to broadband services. However, the issues of connecting Americans to high-speed Internet go further than the expansion of broadband infrastructure. With the introduction of the smartphone to the global market, the ways in which we interact with information have changed drastically. This study seeks to determine whether currently available information services are affordable to the population at large.
Detailed Chemical Abundances in NGC 5824: Another Metal-Poor Globular Cluster with Internal Heavy Element Abundance Variations

description: We present radial velocities, stellar parameters, and detailed abundances of 39 elements derived from high-resolution spectroscopic observations of red giant stars in the luminous, metal-poor globular cluster NGC 5824. We observe 26 stars in NGC 5824 using the Michigan/Magellan Fiber System (M2FS) and two stars using the Magellan Inamori Kyocera Echelle (MIKE) spectrograph. We derive a mean metallicity of [Fe/H]=-1.94+/-0.02 (statistical) +/-0.10 (systematic). The metallicity dispersion of this sample of stars, 0.08 dex, is in agreement with previous work and does not exceed the expected observational errors. Previous work suggested an internal metallicity spread only when fainter samples of stars were considered, so we cannot exclude the possibility of an intrinsic metallicity dispersion in NGC 5824. The M2FS spectra reveal a large internal dispersion in [Mg/Fe], 0.28 dex, which is found in a few other luminous, metal-poor clusters. [Mg/Fe] is correlated with [O/Fe] and anti-correlated with [Na/Fe] and [Al/Fe]. There is no evidence for internal dispersion among the other alpha- or Fe-group abundance ratios. Twenty-five of the 26 stars exhibit a n-capture enrichment pattern dominated by r-process nucleosynthesis ([Eu/Fe]=+0.11+/-0.12; [Ba/Eu]=-0.66+/-0.05). Only one star shows evidence of substantial s-process enhancement ([Ba/Fe]=+0.56+/-0.12; [Ba/Eu]=+0.38+/-0.14), but this star does not exhibit other characteristics associated with s-process enhancement via mass-transfer from a binary companion. The Pb and other heavy elements produced by the s-process suggest a timescale of no more than a few hundred Myr for star formation and chemical enrichment, like the complex globular clusters M2, M22, and NGC 5286.

 In the original description of Lagarinthus corniculatus Meyer (1837) cited two collections (Drège 3423 and Drège s.n.). Drège s.n., from the grassy hillsides at Katberg was not traced. The only duplicates of Drège 3423 were found at at K and P (scan). As the specimen from P is more complete it is chosen as lectotype. The material from K was examined and despite it being only a fragment the identity could be confirmed to be this taxon, based on the flowers only.
 Schlechter (1894c) only listed the collection of Barber 293 when he newly described Gomphocarpus stenoglossus of which two specimens could be traced at GRA and K. The material from K is here selected as lectotype as it represents the full facies of the species better and is more representative of the species than the sheet from GRA. It was interesting that N.E. Brown wrote on the GRA specimen: “Mr. Bowker & Mrs Baber were brother and sister relations and the same plant with the same number appears to have been distributed sometimes under the one name and sometimes under the other” hence the correction of the label at K from Bowker to Barber.

description: We present a class of models in the framework of gauge mediation supersymmetry breaking where the standard model is supplemented by additional U(1) symmetry which acts only on the third generation fermions. The messenger fields carry non-trivial U(1) charge and are vector-like particles under this symmetry. This leads to additional contribution to the soft supersymmetry breaking mass terms for the third generation squarks and sleptons. In this framework we show that the muon g-2 anomaly, the observed 125 GeV Higgs boson mass and the detected relic dark matter abundance (gravitino in our case) can be simultaneously accommodated. The resolution of the muon g-2 anomaly, in particular, yields the result that the first two generation squark masses, as well the gluino mass, should be
Presymmetry in the Standard Model with adulterated Dirac neutrinos
Creators: name: Matute, Ernesto A.
Publisher: name: arXiv
Year: 2015
Subjects: subject: High Energy Physics - Phenomenology (hep-ph)
subject: FOS: Physical sciences

description: Recently we proposed a model for light Dirac neutrinos in which two right-handed (RH) neutrinos per generation are added to the particles of the Standard Model (SM), implemented with the symmetry of fermionic contents. The ordinary one is decoupled via the high scale type-I seesaw mechanism, while the extra pairs off with its left-handed (LH) partner. The symmetry of lepton and quark contents was merely used as a guideline to the choice of parameters because it is not a proper symmetry. Here we argue that the underlying symmetry to take for this correspondence is presymmetry, the hidden electroweak symmetry of the SM extended with RH neutrinos defined by transformations which exchange lepton and quark bare states with the same electroweak charges and no Majorana mass terms in the underlying Lagrangian. It gives a topological character to fractional charges, relates the number of families to the number of quark colors, and now guarantees the great disparity between the couplings of the two RH neutrinos. Thus, Dirac neutrinos with extremely small masses appear as natural predictions of presymmetry, satisfying the 't Hooft's naturalness conditions in the extended seesaw where the extra RH neutrinos serve to adulterate the mass properties in the low scale effective theory, which retains without extensions the gauge and Higgs sectors of the SM. However, the high energy threshold for the seesaw implies new physics to stabilize the quantum corrections to the Higgs boson mass in agreement with the naturalness requirement.

Women's Studies Evaluation

description: Women's studies, because it is highly interdisciplinary and because its materials are often published by small, lesser-known presses, is a notoriously difficult field for which to collect. However, this complexity of collection does nothing to diminish the responsibility of an academic library to support a women's studies program. This study provides an overview of the quality of collection of women's studies materials at ten academic libraries through the list-checking method, sampling from three distinct bibliographies. A comparison of these results to the size of the women's studies programs at those institutions, determined by the number of courses offered by those programs, is used to see whether or not there is a correlation between the size of a women's studies program and the collection relevant to the field.

Scalable cavity quantum electrodynamics system for quantum computing
Creators: name: Aram, Mohammad Hasan

Publisher: name: arXiv
Year: 2015
Subjects: subject: Quantum Physics (quant-ph)
subject: FOS: Physical sciences

description: We introduce a new scalable cavity quantum electrodynamics platform which can be used for quantum computing. This system is composed of coupled photonic crystal (PC) cavities which their modes lie on a Dirac cone in the whole super crystal band structure. Quantum information is stored in quantum dots that are positioned inside the cavities. We show if there is just one quantum dot in the system, energy as photon is exchanged between the quantum dot and the Dirac modes sinusoidally. Meanwhile the quantum dot becomes entangled with Dirac modes. If we insert more quantum dots into the system, they also become entangled with each other.
Bayesian Survival Model based on Moment Characterization

description: Bayesian nonparametric marginal methods are very popular since they lead to fairly easy implementation due to the formal marginalization of the infinite-dimensional parameter of the model. However, the straightforwardness of these methods also entails some limitations: they typically yield point estimates in the form of posterior expectations, but cannot be used to estimate non-linear functionals of the posterior distribution, such as median, mode or credible intervals. This is particularly relevant in survival analysis where non-linear functionals such as e.g. the median survival time, play a central role for clinicians and practitioners. The main goal of this paper is to summarize the methodology introduced in [Arbel et al., Comput. Stat. Data. An., 2015] for hazard mixture models in order to draw approximate Bayesian inference on survival functions that is not limited to the posterior mean. In addition, we propose a practical implementation of an R package called momentify designed for moment-based density approximation, and, by means of an extensive simulation study, we thoroughly compare the introduced methodology with standard marginal methods and empirical estimation.

description: Spin-flip scattering of charge carriers in metals with magnetic defects leads to the low-temperature saturation of the decoherence time, $τ_φ$, of electrons at the value comparable to their spin relaxation time, $τ_s$. In two-dimensional (2D) conductors such a saturation can be lifted by an in-plane magnetic field, $B_\parallel$, which polarizes spins of scatterers without affecting orbital motion of free carriers. Here, we show that in 2D conductors with substantially different values of the g-factors of electrons ($g_e$) and magnetic defects ($g_i$), the decoherence time $τ_φ(B_\parallel)$ (reflected by the curvature of magnetoconductance) displays an anomaly: it first gets shorter, decaying on the scale $B_\parallel\sim \hbar/|g_i-g_e|μ_B τ_s$, before becoming longer at higher values of $B_\parallel$.

description: Use of health tracking devices by Digital Natives has drawn the attention of the health
tracking technology industry. Despite that, it is not clear how those technologies really
work for them in their life contexts, and more study is needed to understand how they
interact with the large amount of information generated by these technologies. My study
borrowed the Savolainen model of everyday information practice as a theoretical lens to
focus on life contexts around the use of health tracking technologies. The data was
collected qualitatively, through semi-structured interviews with nine college students. In
the findings, information practices, personal life contextual factors, and technology
enablement are identified. In evolving relationships among these factors, how
information affordance was offered was discussed. Many information practices still relied
on manual means, as reflected by life contexts.

description: We investigate strong-coupling properties of a two-dimensional ultracold Fermi gas in the normal state. Including pairing fluctuations within the framework of a $T$-matrix approximation, we calculate the distribution function $n({\boldsymbol Q})$ of Cooper pairs in terms of the center of mass momentum ${\boldsymbol Q}$. In the strong-coupling regime, $n({\boldsymbol Q}=0)$ is shown to exhibit a remarkable increase with decreasing the temperature in the low temperature region, which agrees well with the recent experiment on a two-dimensional $^6$Li Fermi gas [M. G. Ries, {\it et. al.}, Phys. Rev. Lett. {\bf 114}, 230401 (2015)]. Our result indicates that the observed remarkable increase of the number of Cooper pairs with zero center of mass momentum can be explained without assuming the Berezinskii-Kosterlitz-Thouless (BKT) transition, when one properly includes pairing fluctuations that are enhanced by the low-dimensionality of the system. Since the BKT transition is a crucial topic in two-dimensional Fermi systems, our results would be useful for the study toward the realization of this quasi-long-range order in an ultracold Fermi gas.

[Z-000001755], ZT! [ZT-00013845]).
 From the original description of Schizoglossum periglossoides, Schlechter (1895a) cited two of his own collections (viz. Schlechter 4027 and 4142), both of which have many good sheets, which could be traced. Kupicha (1984) did include Schizoglossum periglossoides in her revision of the genus, but (and we are in agreement with this) attributed it to the genus Stenostelma. She did, however, labelled the Schlechter 4142 at BOL as lectotype and the material at NH and PRE as isolectotypes but never published it. This intended typification was never formally published. In order to avoid confusion we have followed her decision to select the Schlechter 4142 as type material. There is more material of this collection available, which is more widely distributed and represent the taxon as well as Schlechter 4027. It also overcomes the confusion of some sheets with the number 4027 being wrongly numbered 4029 in some herbaria. Duplicates of syntype Schlechter 4142, collected in Mpumalanga Province, marshy areas near Klein Olipfants (sic.) River, alt. 1615 m on 21 December 1893 can be found at B!, G!, GRA!, MEL!, NH!, PRE!. Z!). The B and Z are orthographically misinterpreted as Schlechter 4029.

Pupil dilation
Eye tracking study

description: Research has demonstrated that pupil dilation can be an effective indicator of human  cognition. When two people converse face-to-face, the body language, gaze, eye  movements or visual cues in general play an instrumental role in determining the course  of the conversation. However, it is not known how our pupils might actually react in a  computer mediated conversation.  Nine subjects participated in a study conducted at the Interaction Design Lab at School of  Information and Library Science, University of North Carolina at Chapel Hill. The study  was divided into two phases. The first phase consisted of a face-to-face conversation and  the second phase consisted of an online chat conversation. An eye tracker was used to  obtain pupil dilation measurements in both phases. The graphs generated by the gaze  tracker were then compared. Overall, mean pupil dilation was greater in the face-to-face  conversation than in the online chat conversation. Implications of this finding for both system design and future research are discussed.
Search for the production of an excited bottom quark decaying to tW in proton-proton collisions at sqrt(s) = 8 TeV

description: A search is presented for a singly produced excited bottom quark (b*) decaying to a top quark and a W boson in the all-hadronic, lepton + jets, and dilepton final states in proton-proton collisions at sqrt(s) = 8 TeV recorded by the CMS experiment at the CERN LHC. Data corresponding to an integrated luminosity of 19.7 inverse femtobarns are used. No significant excess of events is observed with respect to standard model expectations. We set limits at 95% confidence on the product of the b* quark production cross section and its branching fraction to tW. The cross section limits are interpreted for scenarios including left-handed, right-handed, and vector-like couplings of the b* quark and are presented in the two-dimensional coupling plane based on the production and decay coupling constants. The masses of the left-handed, right-handed, and vector-like b* quark states are excluded at 95% confidence below 1390, 1430, and 1530 GeV, respectively, for benchmark couplings. This analysis gives the most stringent limits on the mass of the b* quark to date.

description: Imaging changes in molecular geometries on their natural femtosecond timescale with sub-Angstrom spatial precision is one of the critical challenges in the chemical sciences, since the nuclear geometry changes determine the molecular reactivity. For photoexcited molecules, the nuclear dynamics determine the photoenergy conversion path and efficiency. We performed a gas-phase electron diffraction experiment using Megaelectronvolt (MeV) electrons, where we captured the rotational wavepacket dynamics of nonadiabatically laser-aligned nitrogen molecules. We achieved an unprecedented combination of 100 fs root-mean-squared (RMS) temporal resolution and sub-Angstrom (0.76 Å) spatial resolution that makes it possible to resolve the position of the nuclei within the molecule. In addition, the diffraction patterns reveal the angular distribution of the molecules, which changes from prolate (aligned) to oblate (anti-aligned) in 300 fs. Our results demonstrate a significant and promising step towards making atomically resolved movies of molecular reactions.

description: This study describes a survey of the legacy finding aids in the Southern Historical Collection in the Manuscripts Department at Wilson Library, at the University of North Carolina at Chapel Hill. The survey was conducted to assess the content, scope and quality of the legacy finding aids in preparation for retrospective conversion of those finding aids into Encoded Archival Description (EAD) format. Most archival repositories are confronted with the problem of converting archival description prepared before the advent of computers and modern archival description into EAD. Because retrospective conversion is a resource and labor intensive task, the surveying of the finding aids to be converted is a critical step that should precede the actual encoding. This paper is a case study of one repository's retrospective conversion needs and the survey that resulted as part of the planning process as an example of how an archive can go about classifying their legacy finding aid in order to incorporate retrospective conversion into their departmental workflow.

Subjects: Websites--Use studies

description: This research study aimed at studying the SILS website and understanding if the current design catered well to the needs of three user groups; faculty, staff members, and current students. An online survey questionnaire was created and sent to the listserv of the three user groups.  Out of the 58 responses that were received, 17 were MSIS students, 18 MSLS, 2 BSIS, 5 Faculty, 4 were staff, and the rest chose to remain unidentified. Participants were asked about their usage, level of satisfaction, level of difficulty, and kinds of issues they faced, their opinions and feedback regarding various sections of the SILS website along with the embedded pages within. The responses suggest that although participants were fairly satisfied with the website, there were areas that could be improved in the site’s navigation, deeply embedded links, and inconsistent information.

description: Stellar occultations by asteroids and outer solar system bodies can offer ground based observers with modest telescopes and camera equipment the opportunity to probe the shape, size, atmosphere and attendant moons or rings of these distant objects. The essential requirements of the camera and recording equipment are: good quantum efficiency and low noise, minimal dead time between images, good horological faithfulness of the image time stamps, robustness of the recording to unexpected failure, and low cost. We describe the Astronomical Digital Video occultation observing and recording System (ADVS) which attempts to fulfil these requirements and compare the system with other reported camera and recorder systems. Five systems have been built, deployed and tested over the past three years, and we report on three representative occultation observations: one being a 9 +/-1.5 second occultation of the trans-Neptunian object 28978 Ixion (mv=15.2) at 3 seconds per frame, one being a 1.51 +/-0.017 second occultation of Deimos, the 12~km diameter satellite of Mars, at 30 frames per second, and one being a 11.04 +/-0.4 second occultation, recorded at 7.5 frames per second, of the main belt asteroid, 361 Havnia, representing a low magnitude drop (Dmv = 0.4) occultation.

description: The field of teacher education, like other professional programs such as library science and business administration, constitutes an ill-structured domain wherein students often struggle to apply basic kinds of knowledge acquired in the classroom to complex and disparate real world cases. Traditional pre-service education programs often fail to prepare students adequately for what they will encounter in their jobs. This study examines the relative benefits of employing a hypermedia system based on the principles of Cognitive Flexibility Theory (CFT) to improve outcomes in pre-service teacher education. The experimental group was exposed to the CFT-based system, while the control group instead participated in a field experience. The study's findings suggest that inclusion of CFT-based instructional tools, while improving students' sense of self- efficacy as teachers, does not result in major gains when compared with field experience. While limited in focus the study lends itself well to broader applicability within other professional domains.
Machine Translation from Standard German to Alemannic Dialects

description: Machine translation has been researched using deep neural networks in recent years. These networks require lots of data to learn abstract representations of the input stored in continuous vectors. Dialect translation has become more important since the advent of social media. In particular, when dialect speakers and standard language speakers no longer understand each other, machine translation is of rising concern. Usually, dialect translation is a typical low-resourced language setting facing data scarcity problems. Additionally, spelling inconsistencies due to varying pronunciations and the lack of spelling rules complicate translation. This paper presents the best-performing approaches to handle these problems for Alemannic dialects. The results show that back-translation and conditioning on dialectal manifestations achieve the most remarkable enhancement over the baseline. Using back-translation, a significant gain of +4.5 over the strong transformer baseline of 37.3 BLEU points is accomplished. Differentiating between several Alemannic dialects instead of treating Alemannic as one dialect leads to substantial improvements: Multi-dialectal translation surpasses the baseline on the dialectal test sets. However, training individual models outperforms the multi-dialectal approach. There, improvements range from 7.5 to 10.6 BLEU points over the baseline depending on the dialect.
The Influence of Social Comparison on Fairness in Gain-Loss Contexts

description: Fairness is relative and may be affected by social comparison, especially in decision-making situations. Although some studies using a three-player ultimatum game (UG) with multiple responders have shown that social comparison influences individuals’ fairness behavior in a gain context, the effect of social comparison in a UG with multiple proposers remains unclear, especially in a loss context. To resolve these issues, this study used a modified three-player UG with multiple responders in Experiment 1 and multiple proposers in Experiment 2 to examine the influence of social comparison on fairness-related decision making in gain and loss contexts. The two experiments consistently showed that regardless of the gain or loss context, the fairness level of the offer type and social comparison influenced acceptance rates, reaction times, and fairness ratings. Compared with fair offers, participants were more likely to accept unequal offers, to report higher fairness ratings, and to make decisions more easily when their offers were better than those of the third player. On the contrary, compared with fair offers, participants were more likely to reject unequal offers, to report lower fairness ratings, and to have more difficulty with decisions when their offers were worse than those of the third player. These results demonstrate that responders may care not only about the absolute amount of money they receive but also about their standing relative to other proposers or responders, which deepens understandings of fairness.

 Nomenclatural notes:—In the protologue, the author quotes the Huter, Porta & Rigo’s collection n. 457 of “ Itinere italico III ” and the Rigo’s collection n. 492 (the number 1192 is a typographic error) of “ Iter Italicum quartum ”, whose duplicates are stored is several European herbaria. All the samples of the gathering n. 457, labelled by indelible autograph as “ Vicia argentea Lap. ”, have a manual correction in “ Vicia serinica Uechtr et Huter ”, while the gathering n. 492 is labelled by indelible autograph as “ Vicia Serinica Uechtr. ”. The sheet stored at NAP is a mixture of the collections 457 and 492. We select here as the lectotype a well-preserved specimen of the collection n. 457, because the authors of the name in the corrected label are the same reported in the protologue. The lectotype confirms the current application of the name (e.g., Pignatti 1982a, 2017, Conti et al. 2005, Peruzzi et al. 2014, 2015b, Bartolucci et al. 2018c).

Digital preservation

description: This research explores the current practices, potential methodologies, and user expectations concerning collaborative online filmmaking. Since the concept "Collaborative Online Film Projects (COFPs)" was created for this research and since little research has investigated preservation of online participatory film projects, the paper includes an in-depth review of similar concepts and of literature addressing the preservation of comparable areas of study, including crowdsourced art, interactive virtual worlds, and digital film.
The paper reports on a case study of the COFP platform Wreckamovie.com, including semi-structured interviews of individuals involved with the site. I also analyzed other COFP platform examples: the still-active hitRECord.org and the now inactive opensourcecinema.org and the project A Swarm of Angels. Though more research is necessary, this paper concludes that though users value the preservation of their work, there is minimal communication about collaboratively preserving work and little engagement with active preservation.
Effect of Perturbative Hexagonal Warping on Quantum Capacitance in Ultra-Thin Topological Insulators

description: Ultra-thin 3D topological insulators provide a stage to study the surface physics of such materials by minimizing the bulk contribution. Further, the experimentally verified snowflake like structure of the Fermi surface leads to a hexagonal warping term, and this discourse examines it as a perturbation in the presence of a magnetic field. We find that there are corrections to both energy dispersion and eigenstates which in turn alter the density of states in the presence of a magnetic field. Both the quantum capacitance and the Hall coefficient are evaluated analytically and it is shown here that we recover their established forms along with small corrections which preserve the object of treating hexagonal warping perturbatively. In our approach, the established Hall conductivity expression develops several minute correction terms and thus its behavior remains largely unaffected due to warping. The zero-temperature quantum capacitance exhibits SdH oscillations with reduced frequencies, with a lowered average capacitance with increased warping of the Fermi surface, while maintaining the usual amplitudes.
