Search for the Standard Model Higgs boson produced in association with top quarks and decaying into a $b\bar{b}$ pair in $pp$ collisions at $\sqrt{s}$ = 13 TeV with the ATLAS detector
Creators: name: ATLAS Collaboration
Publisher: name: Deutsches Elektronen-Synchrotron, DESY, Hamburg
Year: 2017

description: A search for the Standard Model Higgs boson produced in association with a top-quark pair, $t\bar{t}H$, is presented. The analysis uses 36.1 fb$^{-1}$ of $pp$ collision data at $\sqrt{s}$ = 13 TeV, collected with the ATLAS detector at the Large Hadron Collider in 2015 and 2016. The search targets the $H \to b\bar{b}$ decay mode. The selected events contain either one or two electrons or muons from the top-quark decays, and are then categorized according to the number of jets and how likely these are to contain $b$-hadrons. Multivariate techniques are used to discriminate between signal and background events, the latter being dominated by $t\bar{t}$ + jets production. For a Higgs boson mass of 125 GeV, the ratio of the measured $t\bar{t}H$ signal cross-section to the Standard Model expectation is found to be $\mu = 0.84^{+0.64}_{-0.61}$. A value of $\mu$ greater than 2.0 is excluded at 95% confidence level while the expected upper limit is $\mu < 1.2$ in the absence of a $t\bar{t}H$ signal.
Search for electroweak production of supersymmetric states in scenarios with compressed mass spectra at $\sqrt{s}=13$ TeV with the ATLAS detector
Creators: name: ATLAS Collaboration
Publisher: name: Deutsches Elektronen-Synchrotron, DESY, Hamburg
Year: 2017

description: A search for electroweak production of supersymmetric particles in scenarios with compressed mass spectra in final states with two low-momentum leptons and missing transverse momentum is presented. This search uses proton-proton collision data recorded by the ATLAS detector at the Large Hadron Collider in 2015-2016, corresponding to 36.1 fb$^{-1}$ of integrated luminosity at $\sqrt{s}=13$ TeV. Events with same-flavor pairs of electrons or muons with opposite electric charge are selected. The data are found to be consistent with the Standard Model prediction. Results are interpreted using simplified models of R-parity-conserving supersymmetry in which there is a small mass difference between the masses of the produced supersymmetric particles and the lightest neutralino. Exclusion limits at 95% confidence level are set on next-to-lightest neutralino masses of up to 130 GeV for Higgsino production and 170 GeV for wino production, and sleptons masses of up to 180 GeV for pair production of sleptons. In the compressed mass regime, the exclusion limits extend down to mass splittings of 3 GeV for Higgsino production, 2.5 GeV for wino production, and 1 GeV for slepton production. The results are also interpreted in the context of a radiatively-driven natural supersymmetry model with non-universal Higgs boson masses.

Scholarly publishing

description: This study examines how a sample of scholarly publishers and granting organizations have integrated the Open Researcher and Contributor ID (ORCID) into their grant application and manuscript submission workflows. The study was conducted to discover what benefits these organizations gain from using the ORCID unique author identifiers and how effective they are at introducing scholars to ORCID as a service.
The data was collected through interviews of representatives from a sample of publishing and funding organizations: the National Institutes of Health, the U.S. Department of Energy's Office of Science and Technical Information, the Wellcome Trust, Autism Speaks, Elsevier, and Oxford University Press. A representative from eJournalPress, a software company that provides manuscript management tools was also interviewed. The result is an analysis of best practices for ORCID integration at these types of organizations and suggestions for improvement. The conclusions drawn are generalizable to other institutions seeking to adopt ORCID themselves.

description: Given a certain kind of linear representation of a reductive group, referred to as a quasi-symmetric representation in recent work of Špenko and Van den Bergh, we construct equivalences between the derived categories of coherent sheaves of its various geometric invariant theory (GIT) quotients for suitably generic stability parameters. These variations of GIT quotient are examples of more complicated wall crossings than the balanced wall crossings studied in recent work on derived categories and variation of GIT quotients. Our construction is algorithmic and quite explicit, allowing us to: 1) describe a tilting vector bundle which generates the derived category of such a GIT quotient, 2) provide a combinatorial basis for the K-theory of the GIT quotient in terms of the representation theory of G, and 3) show that our derived equivalences satisfy certain relations, leading to a representation of the fundamental groupoid of a "Kähler moduli space" on the derived category of such a GIT quotient. Finally, we use graded categories of singularities to construct derived equivalences between all Deligne-Mumford hyperkähler quotients of a symplectic linear representation of a reductive group (at the zero fiber of the algebraic moment map and subject to a certain genericity hypothesis on the representation), and we likewise construct actions of the fundamental groupoid of the corresponding Kähler moduli space.

description: We study the spectral properties of a family of quantum antiferromagnets on two-dimensional (2D) lattices. This family of models is obtained by a deformation of the well-studied 2D quantum antiferromagnetic model of Affleck, Kennedy, Lieb and Tasaki (AKLT); they are described by two-body, frustration-free Hamiltonians on a three-colourable lattice of spins. Although the existence of a spectral gap in the 2D AKLT model remains an open question, we rigorously prove the existence of a gap for a subset of this family of quantum antiferromagnets. Along with providing new progress for the gap problem in AKLT-type antiferromagnets in 2D, this result has implications for the theory of quantum computation as it provides a family of two-body Hamiltonians for which the ground state is a resource for universal quantum computation and for which a spectral gap is proven to exist.

description: Internet-based delivery of evidenced-based Value Based Counseling (VBC) fulfills the demand for a low threshold, culturally-sensitive and short-term intervention located at a level below specialized mental health care which can help those who do not require such specialized care to activate their resources and to regain their everyday functioning quickly. A pretest–posttest design with a historical control group was used to investigate the efficacy of internet-delivered VBC in comparison with in-person VBC provided to 102 help-seeking clients, who included refugees residing mainly in Germany. Intention-to-treat analyses concluded that internet-delivered VBC, comparable to in-person VBC, resulted in a significant reduction of depression, posttraumatic stress symptoms, perceived stress, somatic complaints, and daily functioning impairment at the post-test.
Precision age indicators that exploit chemically peculiar stars

description: We would like to find a way to improve the determination of galaxy star formation history from integrated light spectroscopy. To this end, several classes of chemically peculiar (CP) stars arise during the course of normal evolution in single stars and noninteracting binary stars. An aging stellar population has periods of time in which CP stars contribute to the integrated light, and others in which the contributions fade. The HgMn stars, for example, occupy a narrow temperature range of 10500 to 16000 K, which maps to a narrow range of ages. Wolf-Rayet stars, He-poor stars, Bp-Ap stars, Am-Fm stars, and C stars all become very common in a normal stellar population at various ages between zero and several Gyr, fading in and out in a way that is analogous to features used in stellar spectral classification. We examine population fractions and light fractions in order to assess the feasibility of using CP stars as age tracers. We find that, even though CP stars do not usually dominate in number, there are enough of them so that the CP spectral features are detectable in high-quality integrated spectra of young and intermediate age stellar populations. The new technique should be calibratable and useful. Furthermore, using CP signatures as age dating tools sidesteps reliance on photometry that is susceptible to dust and Balmer features that are susceptible to nebular fill-in.

Locating the Research Methods of Doctoral Students: The Results of Interviews with Current Religious Studies Doctoral Students

description: This paper describes a study conducted to better understand both the ways in which current PhD students in religious studies gather research and which library resources they are using. PhD students provide invaluable insight regarding shifts in research, library science, and publishing, yet little research has been conducted with them in comparison to their more senior faculty-status colleagues. In order to correct that oversight, this study was designed in an effort to improve PhD student’s instruction in the art of research and to improve library assistance with PhD student-specific research bottlenecks. This study used a semi-structured interview protocol to solicit the experiences of current religious studies doctoral students on the issue, seeking five, and garnering seven usable responses. Interview results indicate that in comparison to current religious studies faculty at the same institution, doctoral students are 1.) more comfortable identifying their work as data; 2.) incorporating more technology into their research methods and storage; and 3.) weighing in more heavily on the importance of public engagement. They do, however, still disagree amongst themselves on such issues as when to incorporate nontraditional publishing avenues into their portfolios. The results of this study are of primary interest to UNC University Libraries staff, academic library staff members in general through professional organizations, humanities faculty across the country, researchers studying trends in higher education, and by other PhD students.
Spectral Properties of Oriented Hypergraphs

Publisher: name: arXiv
Year: 2015
Subjects: subject: Combinatorics (math.CO)
subject: FOS: Mathematics

description: An oriented hypergraph is a hypergraph where each vertex-edge incidence is given a label of $+1$ or $-1$. The adjacency and Laplacian eigenvalues of an oriented hypergraph are studied. Eigenvalue bounds for both the adjacency and Laplacian matrices of an oriented hypergraph which depend on structural parameters of the oriented hypergraph are found. An oriented hypergraph and its incidence dual are shown to have the same nonzero Laplacian eigenvalues. A family of oriented hypergraphs with uniformally labeled incidences is also studied. This family provides a hypergraphic generalization of the signless Laplacian of a graph and also suggests a natural way to define the adjacency and Laplacian matrices of a hypergraph. Some results presented generalize both graph and signed graph results to a hypergraphic setting.

description: This study looks at the top 10 ranked accredited library and information schools (LIS) across the United States. Document reviews of these 12 LIS schools were conducted to examine their approaches to big data by looking at course work, offered specializations and certificates and employed professors whose focus is within the field. Overall, this study showed that while many are incorporating big data and data management into their programs through courses and by employing professors, there is still room for improvement, especially in regards to offering specializations and certificates. A ranking of each school was completed at the conclusion of the study. The findings of this research may be of interest to incoming LIS students, current LIS students and faculty.

description: We report a numerical calculation of the total number of disordered jammed configurations $Ω$ of $N$ repulsive, three-dimensional spheres in a fixed volume $V$. To make these calculations tractable, we increase the computational efficiency of the approach of Xu et al. (Phys. Rev. Lett. 106, 245502 (2011)) and Asenjo et al. (Phys. Rev. Lett. 112, 098002 (2014)) and we extend the method to allow computation of the configurational entropy as a function of pressure. The approach that we use computes the configurational entropy by sampling the absolute volume of basins of attraction of the stable packings in the potential energy landscape. We find a surprisingly strong correlation between the pressure of a configuration and the volume of its basin of attraction in the potential energy landscape. This relation is well described by a power law. Our methodology to compute the number of minima in the potential energy landscape should be applicable to a wide range of other enumeration problems in statistical physics, string theory, cosmology and machine learning, that aim to find the distribution of the extrema of a scalar cost function that depends on many degrees of freedom.

description: Ultra-high energy cosmic rays (UHECRs) are the messengers of the most extreme physics in the cosmos; however, efforts to identify their origins have thus far been thwarted by the fact that they don’t point back to their sources. Using statistical studies cross-correlating UHECR arrival directions with astrophysical catalogs, the ground-based Pierre Auger Observatory has reported hints of a correlation with nearby starburst galaxies, as well as lower-significance correlations with other classes of astrophysical sources. Space-based UHECR experiments, such as POEMMA and ZAP, will monitor large interaction volumes on the Earth or the Moon. Within a few years of mission operation time, both missions will achieve unprecedented exposures at energies above 40 EeV across the entire sky. We present studies of the cross-correlation between UHECR event arrival directions and astrophysical catalogs as motivated by expectations for the detector performance for POEMMA and ZAP. We find that both POEMMA and ZAP will achieve 5σ discovery reach for many plausible astrophysical scenarios.

description: Under current law records made in the transaction of public business are considered public and subject to inspection. This aspiration of an open and accountable government is not as simple as the broad statutes may seem to imply. Public content is being created at an exponential rate and policies guiding the management of public records are confusing. Current assumptions are incentives for public officials just to keep all records indefinitely. A flawed system of public record-keeping harms the public's assurance of meaningful knowledge about its government's decisions. This paper addresses the realities of public information creation, retention, and management by highlighting problems that could arise in public record-keeping. These realities are considered alongside core principles of record-keeping and original intent of public records law. A look into core principles could be the essential starting point for efforts to reform public records law.

We study the magnetotransport in these materials using chiral kinetic theory to describe within the same framework both the negative magnetoresistance caused by chiral magnetic effect and quantum oscillations in the magnetoresistance due to the existence of the Fermi surface. We discuss the relevance of obtained results to recent measurements on ${\rm Cd_3As_2}$.

description: The shape of the building blocks plays a crucial role in directing self-assembly towards desired architectures. Out of the many different shapes, helix has a unique position. Helical structures are ubiquitous in nature and a helical shape is exhibited by the most important biopolymers like polynucleotides, polypeptides and polysaccharides as well as by cellular organelles like flagella. Helical particles can self-assemble into chiral superstructures, which may have a variety of applications, e.g. as photonic (meta)materials. However,a clear and definite understanding of these structures has not been entirely achieved yet. We have recently undertaken an extensive investigation on the phase behaviour of hard helical particles, using numerical simulations and classical density functional theory. Here we present a detailed study of the phase diagram of hard helices as a function of their morphology. This includes a variety of liquid-crystal phases, with different degrees of orientational and positional ordering. We show how, by tuning the helix parameters, it is possible to control the organization of the system. Starting from slender helices, whose phase behaviour is similar to that of rodlike particles, the increase in curliness leads to the onset of azimuthal correlations between the particles and the formation of phases specific to helices. These phases feature a new kind of screw order, of which there is experimental evidence in colloidal suspensions of helical flagella.

Invariant measure and long time behavior of regular solutions of the Benjamin-Ono equation
Creators: name: Sy, Mouhamadou
Publisher: name: arXiv
Year: 2016
Subjects: subject: Analysis of PDEs (math.AP)
subject: FOS: Mathematics

description: The Benjamin-Ono equation describes the propagation of internal waves in a stratified fluid. In the present work, we study large time dynamics of its regular solutions via some probabilistic point of view. We prove the existence of an invariant measure concentrated on $C^\infty(\T)$ and establish some qualitative properties of this measure. We then deduce a recurrence property of regular solutions and other corollaries using ergodic theorems. The approach used in this paper applies to other equations with infinitely many conservation laws, such as the KdV and cubic Schrödinger equations in 1D. It uses the fluctuation-dissipation-limit approach and relies on a \textit{uniform} smoothing lemma for stationary solutions to the damped-driven Benjamin-Ono equation.

description: This paper presents the results of a survey of 30 adults aged 55 and older, who had taken multiple prescription medications in the past two years. The purpose of the study was to determine how older adults manage their medication information currently, what information they save and share, and how they wish to manage medication information in an electronic environment, such as a personal health record. Adults in the survey shared information most frequently with their doctors, and with friends and family. They usually shared basic information about a medication, including its name, dose, and the frequency with which it is taken. Nearly half used an artifact, such as a list, to keep track of and share their information. Nearly a third of participants desired to keep an electronic record, suggesting that a percentage of the older adult population would be open to using electronic records to manage medication information.

description: Grapevines subjected to applications of nitrogen (N) doses on the soil surface can use only a small amount of the nutrient, probably because of losses, such as nitrous oxide (N2O) emissions to the atmosphere. An alternative to reduce these N losses may be the application of N via fertigation. The study aimed to evaluate the N2O emissions and grape yield (Vitis vinifera L.), in grapevines submitted to the application of modes and doses of N cultivated in sandy soil in a subtropical climate. 'Alicante Bouschet' grapevines were subjected to a factorial scheme with three N rates: 0, 40 and 80 kg N ha-1 year-1; and two application modes: surface (NS) and via fertigation (NF). Evaluations of N2O emissions and ammonium (NH4+) and nitrate (NO3-) contents in the soil, N concentration in leaves, grape yield, and number of clusters per plant were carried out. Grapevines cultivated with applications of 40 and 80 kg N ha-1 yr-1, in NF and NS modes, respectively, present-ed higher N2O emissions. N2O emission peaks occurred in the first 9 days after N application. Cumulative N2O emissions ranged from 161.74 ± 34.67 to 496.18 ± 37.00 g ha-1 of N2O-N, in soils that received 0 and 40 kg N ha-1 yr-1, respectively, both in NF mode. Accumulated N2O emissions had a linearly positive relation with the mineral N content in the soil (NH4+ and NO3-) and these had a negative relation with grape yield.

description: The benefits of collaboration between universities and industry have been widely recognised, however, little practical guidance is provided as to how to establish successful strategic collaborations and support the different types of interactions between these two very different stakeholders. We have successfully adapted and used innovation roadmapping as a method to help these two heterogeneous partners to establish collaborations of common interest. The approach has been used twenty times to establish collaborations between firms and academia at various scales: a) the whole university, b) a large part of a university i.e. several departments, and c) specific academic groups. Feedback showed that roadmapping can be a powerful method for aligning the needs of the two communities, helping to identify common priorities and aiding communication and clarity in the collaboration activities. Overall, participants from both communities indicated that the method was simulating and provided new and useful insights.

description: Let $F$ be a $p$-adic field and $E/F$ be a quadratic extension. In this paper, we prove the local converse theorem for generic representations of $\textrm{U}_{E/F}(2,2)$ if $E/F$ is unramified or the residue characteristic of $F$ is odd. Our method is purely local and analytic, and the same method also gives the local converse theorem for $\textrm{Sp}_4(F)$ and $\widetilde {\textrm{Sp}}_4(F)$ if the residue characteristic of $F$ is odd.

Recruiting for librarianship

description: This study documents the importance of recruitment efforts to provide a stronger presence of minority students in the library and information science profession and library and information science programs in top-ranked American Library Association (ALA) programs. Using a career choice model an instrument was developed to survey minority students at graduate and professional school fairs at five historically black colleges and universities (HBCUs) to determine their awareness, knowledge, and interest in information technology and other factors impacting their decisions when deciding on a particular graduate program to attend. Results showed that increased familiarity and awareness of careers in information technology with knowledge of opportunities at library and information science programs can lead to greater numbers for minority students selecting the field.
Extension and parameterization of high-order density dependence in Skyrme forces

description: The three-body force is indispensable in nuclear energy density functionals which leads to a density dependent two-body term in the Hartree-Fock approach. Usually a single factional power of density dependency has been adopted. We consider the possibility of an additional higher-order density dependence in extended Skyrme forces. As a result, new extended Skyrme parametertizations based on the SLy4 force are obtained and the improvements in descriptions of global nuclei have been demonstrated. The higher-order term can also substantially affect nuclear properties in the high density region in general ways.

description: This paper analyzes the results from a survey conducted regarding librarians' perceptions involving the merging of the government documents department with the reference department in academic libraries, and how reference service is thus affected. The consequences of a merger can be manifested in different ways and can often be the result of the way the actual merger was handled. The focus of this paper is whether the level of government documents reference service diminishes when the documents department is merged with the reference department in a library. The purpose of this study is to evaluate past experiences in order to provide a synthesis of experiences and lessons learned for those contemplating such a merger in the future.
A Profile of Scholarly Communications Innovations: Looking at the Faculty Profile System and its Role in the Changing World of Scholarly Communications

description: In her 1997 article ‘Scholarly Communication—Historical Developments and New Possibilities’,Nancy Fjällbrant noted that “we are on the greatest change in scholarly communication andknowledge transfer the world has ever seen”. 20 years later, the world of scholarlycommunications is still in a period of rapid change. I focused on one scholarly communicationtool, the scholarly profile system, and examined first the theoretical possibility of this tool toreplace scholarly journals (through the lens of Bijker and Pinch’s social construction oftechnology) and then I interviewed users to examine uses, trends and issues with the scholarlyprofile system. I ultimately concluded that although the system is functional in the currentclimate of scholarly communications, it will have to answer questions about access, use andoutcomes in order to continue meeting the needs of scholars and researchers.
On spurious detection of linear response and misuse of the fluctuation-dissipation theorem in finite time series

description: Using a sensitive statistical test we determine whether or not one can detect the breakdown of linear response given observations of deterministic dynamical systems. A goodness-of-fit statistics is developed for a linear statistical model of the observations, based on results on central limit theorems for deterministic dynamical systems, and used to detect linear response breakdown. We apply the method to discrete maps which do not obey linear response and show that the successful detection of breakdown depends on the length of the time series, the magnitude of the perturbation and on the choice of the observable. We find that in order to reliably reject the assumption of linear response for typical observables sufficiently large data sets are needed. Even for simple systems such as the logistic map, one needs of the order of $10^6$ observations to reliably detect the breakdown, if less observations are available one may be falsely led to conclude that linear response theory is valid. The amount of data required is larger the smaller the applied perturbation. For judiciously chosen observables the necessary amount of data can be drastically reduced, but requires detailed {\em{a priori}} knowledge about the invariant measure which is typically not available for complex dynamical systems. Furthermore we explore the use of the fluctuation-dissipation theorem (FDT) in cases with limited data length or coarse-graining of observations. The FDT, if applied naively to a system without linear response, is shown to be very sensitive to the details of the sampling method, resulting in erroneous predictions of the response.

description: Using the $\hbar$-expansion of the Green's function of the Hartree-Fock-Bogoliubov equation, we extend the second-order Thomas-Fermi approximation to generalized superfluid Fermi systems by including the density-dependent effective mass and the spin-orbit potential. We first implement and examine the full correction terms over different energy intervals of the quasiparticle spectra in calculations of finite nuclei. Final applications of this generalized Thomas-Fermi method are intended for various inhomogeneous superfluid Fermi systems.
