The role of dynamo instabilities in the dynamics of solar-like cool stars

description: For many decades, several research groups have developed sophisticated numerical models of the dynamics and magnetism of the Sun. As our central star, explaining, understanding, and predicting its magnetic activity is a very important goal, as the effects on our hi-tech civilisation can be very harmful. Despite of all these efforts, reproducing the solar non-uniform rotation and its observed cyclic magnetic field evolution correctly in one and the same model are still challenging, and all efforts seem to fail in some respect or another. Arguably, the numerical experiments are far removed from the parameter regime of the Sun, and no clear asymptotic behaviour has been found yet in any of them. We are, however, just approaching the regime, where both of the relevant dynamo instabilities, responsible for generating the different constituents of the solar magnetic field, are captured by the numerical models. These are the large-scale dynamo, generating the global solar magnetic field, and the small-scale dynamo, generating a fluctuating field, the latter of which requires extremely high-resolution simulations to be properly captured in global-scale models. Fluctuations are also generated from the tangling of the global magnetic field by turbulent motions, ubiquitous in the convection zone of the Sun, hence distinguishing between these two mechanisms observationally, and also numerically, is very challenging. In this contribution, I will review the results from the state-of-the-art numerical models, capable of simultaneously capturing these two dynamo instabilities under solar-like conditions, and present one possible interpretation of the results collected.

description: Tune-out wavelengths measured with an atom interferometer are sensitive to laboratory rotation rates because of the Sagnac effect, vector polarizability, and dispersion compensation. We observed shifts in measured tune-out wavelengths as large as 213 pm with a potassium atom beam interferometer, and we explore how these shifts can be used for an atom interferometer gyroscope.

description: Numerous articles on the reasons for web log analysis exist.  Much of the web-log analysis literature deals with how to collect data, technical aspects, and how to select the appropriate software for collecting the data; it will be the aim of this paper to create a user profile for USA Cycling's website by using WebTrends software to analyze web-log files.  After the user profile has been developed, it will be shown that the web-log analysis of USA Cycling's website can be used to make daily and long term decisions about the its functionality.  In addition, this paper will cover the basic issues of web-log analysis as well as exploring the practical application for USA Cycling.  To accomplish these tasks, USA Cycling's web-logs were analyzed from August 1999 to April 2002 using WebTrends log analyzing software and key questions were developed based on observations and sent to USA Cycling for clarification.

description: Parasitic worms (i.e., helminths) commonly infect multiple hosts in succession. With every transmission step, they risk not infecting the next host and thus dying before reproducing. Given this risk, what are the benefits of complex life cycles? Using a dataset for 973 species of trophically transmitted acanthocephalans, cestodes, and nematodes, we tested whether hosts at the start of a life cycle increase transmission and whether hosts at the end of a life cycle enable growth to larger, more fecund sizes. Helminths with longer life cycles, that is, more successive hosts, infected conspicuously smaller first hosts, slightly larger final hosts, and exploited trophic links with lower predator–prey mass ratios. Smaller first hosts likely facilitate transmission because of their higher abundance and because parasite propagules were the size of their normal food. Bigger definitive hosts likely increase fecundity because parasites grew larger in big hosts, particularly endotherms. Helminths with long life cycles attained larger adult sizes through later maturation, not faster growth. Our results indicate that complex helminth life cycles are ubiquitous because growth and reproduction are highest in large, endothermic hosts that are typically only accessible via small intermediate hosts, that is, the best hosts for growth and transmission are not the same.
Renormalizing a Viscous Fluid Model for Large Scale Structure Formation

description: Using the Stochastic Adhesion Model (SAM) as a simple toy model for cosmic structure formation, we study renormalization and the removal of the cutoff dependence from loop integrals in perturbative calculations. SAM shares the same symmetry with the full system of continuity+Euler equations and includes a viscosity term and a stochastic noise term, similar to the effective theories recently put forward to model CDM clustering. We show in this context that if the viscosity and noise terms are treated as perturbative corrections to the standard eulerian perturbation theory, they are necessarily non-local in time. To ensure Galilean Invariance higher order vertices related to the viscosity and the noise must then be added and we explicitly show at one-loop that these terms act as counter terms for vertex diagrams. The Ward Identities ensure that the non-local-in-time theory can be renormalized consistently. Another possibility is to include the viscosity in the linear propagator, resulting in exponential damping at high wavenumber. The resulting local-in-time theory is then renormalizable to one loop, requiring less free parameters for its renormalization.

 Distribution in India: Manipur (Chapki river, Thoubal district, Imphal).
 Notes: Populations of Lemanea specimens in India have been reported only from Manipur state and from five different rivers: Chapki, Imphal, Iril, Manipur and Thoubal. Synopsis of references (1973–2014) for the five specific epithets applied to these populations is given by Ganesan et al. (2015). Lemanea populations in the Manipur state constitute not only an important source of dietary supplement, but also used as medicines for several health problems by the local tribal populations. Since the populations are seasonal and occur only during the colder months of the year (November to February), a detailed study of Lemanea plants from other areas of the state is necessary to learn about the presence of more than one species.

description: The study of solutions to polynomial equations over finite fields has a long history in mathematics and is an interesting area of contemporary research. In recent years the subject has found important applications in the modelling of problems from applied mathematical fields such as signal analysis, system theory, coding theory and cryptology. In this connection it is of interest to know criteria for the existence of squares and other powers in arbitrary finite fields. Making good use of polynomial division in polynomial rings over finite fields, we have examined a classical criterion of Euler for squares in odd prime fields, giving it a formulation which is apt for generalization to arbitrary finite fields and powers. Our proof uses algebra rather than classical number theory, which makes it convenient when presenting basic methods of applied algebra in the classroom.

description: This study describes Virtual Local Area Network (VLAN) technologies, which allow a single, physical computer network to be divided into separate, logical networks, such that it appears to the end user that he or she is ona separate, physical network from users on other VLANs.  VLAN technology can be used to imporve network performance while minimizing or eliminating problems encountered in large networks.  VLANs can also enhance security and reduce the resources required to administer the network.  This study combines descriptive research with a case study of the use of VLANs at the University of North Carolina at Chapel Hill.  General networking and VLAN-specific concepts are synthesized from the literature, and the experience of UNC-CH's Academic Technology and Networks (ATN) department with their VLAN implementation is analyzed.

description: Errors in the data and the forward operator of an inverse problem can be handily modelled using partial order in Banach lattices. We present some existing results of the theory of regularisation in this novel framework, where errors are represented as bounds by means of the appropriate partial order. We apply the theory to Diffusion Tensor Imaging, where correct noise modelling is challenging: it involves the Rician distribution and the nonlinear Stejskal-Tanner equation. Linearisation of the latter in the statistical framework would complicate the noise model even further. We avoid this using the error bounds approach, which preserves simple error structure under monotone transformations.

description: Clutter is an aspect of web aesthetics that has come to the fore in recent years as the research community works toward a fuller understanding of what clutter is and how it affects users’ perceptions and performance with interfaces. In this paper, I examine the possible effects of cultural background on users’ first impressions of display clutter in website designs. The study was conducted using a series of five-second impression tests that asked participants from two distinct cultural groups to view a set of screenshots encompassing multiple levels of clutter, as measured by a JPEG file size measure. Results showed some effects from cultural background on perceptions of clutter, raised some issues with the cross-cultural applicability of the objective JPEG measure’s ability to predict subjective judgments, and provide some evidence that organization is a key distinguishing factor between visual complexity and clutter.

description: We report the results of a muon-spin relaxation ($μ$SR) investigation of La$_{2-x}$Sr$_{x}$CoO$_{4}$, an antiferromagnetic insulating series which has been shown to support charge ordered and magnetic stripe phases and an hourglass magnetic excitation spectrum. We present a revised magnetic phase diagram, which shows that the suppression of the magnetic ordering temperature is highly sensitive to small concentrations of holes. Distinct behavior within an intermediate $x$ range ($0.2 \leq x \lesssim 0.6$) suggests that the putative stripe ordered phase extends to lower $x$ than previously thought. Further charge doping ($0.67 \leq x \leq 0.9$) prevents magnetic ordering for $T \gtrsim 1.5~{\rm K}$

description: We present direct spectroscopic modeling of 11 high-S/N observed spectra of the Type Ia SN 2010kg, taken between -10 and +5 days with respect to B-maximum. The synthetic spectra, calculated with the SYN++ code, span the range between 4100 and 8500 Å. Our results are in good agreement with previous findings for other Type Ia SNe. Most of the spectral features are formed at or close to the photosphere, but some ions, like Fe II and Mg II, also form features at ~2000 - 5000 km s$^{-1}$ above the photosphere. The well-known high-velocity features of the Ca II IR-triplet as well as Si II $λ$6355 are also detected. The single absorption feature at ~4400 Å, which usually has been identified as due to Si III, is poorly fit with Si III in SN 2010kg. We find that the fit can be improved by assuming that this feature is due to either C III or O II, located in the outermost part of the ejecta, ~4000 - 5000 km s$^{-1}$ above the photosphere. Since the presence of C III is unlikely, because of the lack of the necessary excitation/ionization conditions in the outer ejecta, we identify this feature as due to O II. The simultaneous presence of O I and O II is in good agreement with the optical depth calculations and the temperature distribution in the ejecta of SN 2010kg. This could be the first identification of singly ionized oxygen in a Type Ia SN atmosphere.

description: The top quark is the most massive known elementary particle, and plays a pivotal role in our understanding of particle physics. Its unique properties offer valuable insights into the Standard Model and potential hints for physics beyond the Standard Model. In this thesis we present a precision measurement of the polarization of top quarks and spin correlations between top-antitop (ttbar) pairs using Run-II datasets collected from the Compact Muon Solenoid detector at the Large Hadron Collider. In the first part of this thesis we introduce the theoretical framework of the Standard Model and its predictions regarding top quark spin polarization and ttbar spin correlations. Next, we describe the experimental setup, reconstruction techniques, and Monte Carlo simulations used in this research. Subsequently, details of the measurement, including event selection, top quark reconstruction, and unfolding are described. The analysis achieves exceptional signal purity and precision with respect to previous measurements. The measured values of coefficients are in agreement with Standard Model expected values as well as theoretical predictions at NLO in QCD. In a first, we provide provide double-differential cross sections of top quark spin polarizations and ttbar spin correlations, as a function of the invariant mass of the ttbar system. We expect the results from the final CMS publication to supersede any results presented in the measurement part of this thesis document. In the final section of this thesis, we present a projection study of top quark spin polarization and tt ̄ spin correlations at the upcoming High Luminosity LHC. We present projections of the fraction of SM-like events and show that the upcoming detector could reduce uncertainties by as much as a factor 2. An alternative to the SM scenario is also considered in the form of Super Symmetry, and it is shown that we can significantly increase the ultimate reach of the LHC to discover top squarks in the degenerate mass corridor in the top squark-neutralino plane, or in the absence of a discovery exclude top squarks up to 600 GeV.

description: The space-based gravitational-wave detector eLISA has been selected as the ESA L3 mission, and the mission design will be finalised by the end of this decade. To prepare for mission formulation over the next few years, several outstanding and urgent questions in data analysis will be addressed using mock data challenges, informed by instrument measurements from the LISA Pathfinder satellite launching at the end of 2015. These data challenges will require accurate and computationally affordable waveform models for anticipated sources such as the extreme-mass-ratio inspirals (EMRIs) of stellar-mass compact objects into massive black holes. Previous data challenges have made use of the well-known analytic EMRI waveforms of Barack and Cutler, which are extremely quick to generate but dephase relative to more accurate waveforms within hours, due to their mismatched radial, polar and azimuthal frequencies. In this paper, we describe an augmented Barack-Cutler model that uses a frequency map to the correct Kerr frequencies, along with updated evolution equations and a simple fit to a more accurate model. The augmented waveforms stay in phase for months and may be generated with virtually no additional computational cost.

description: As electronic communication has become increasingly widespread, the ability to easily share information has led to discussions of public access to the results of research that is funded with tax dollars. However, whether these articles should be freely available is uncertain, as publishers invest in their production. Academic librarians have an important position in the issue and can present information on current possibilities and developments as they evolve, especially as librarians form connections with stakeholders including researchers, publishers, and the public.  This study examines responses of academic librarians to a recent government request for information on public access to peer-reviewed scholarly publications resulting from federally funded research. Content analysis is presented, highlighting reasons academic librarians believe government should increase public access to these research results. Thematic trends seen in comment subgroups, such as those from research university libraries, public institution libraries, and private institution libraries are also compared and interpreted.

description: We study the next-to-minimal supersymmetric standard model (NMSSM) with the TeV scale mirage mediation, which is known as a solution for the little hierarchy problem in supersymmetry. Our previous study showed that 125 GeV Higgs boson is realized with O(10) % fine-tuning for 1.5 TeV gluino (1 TeV stop) mass. The $μ$ term could be as large as 500 GeV without sacrificing the fine-tuning thanks to a cancellation mechanism. The singlet-doublet mixing is suppressed by $\tanβ$. In this paper, we further extend this analysis. We argue that approximate scale symmetries play a role behind the suppression of the singlet-doublet mixing. They reduce the mixing matrix to a simple form that is useful to understand the results of the numerical analysis. We perform a comprehensive analysis of the fine-tuning including the singlet sector by introducing a simple formula for the fine-tuning measure. This shows that the singlet mass of the least fine-tuning is favored by the LEP anomaly for moderate $\tanβ$. We also discuss prospects for the precision measurements of the Higgs couplings at LHC and ILC and direct/indirect dark matter searches in the model.

description: This paper examines the role an author's ethnicity plays in the depiction of slaves and the portrayal of slavery in historical fiction. In this study, five books by African American authors and five books by white authors published between 1981 and 2001 were subjected to latent content analysis. This study concluded that while authors of both races universally condemn slavery, there is a difference in the ways the write about the institution. African Americans focus on character development as affected by slavery, but white authors focus on the horrific issues surrounding slavery.

description: Wine counterfeiting has been posing significant challenges to wine industry, and has undermined the international wine trading market and the global economy hugely. The situation of counterfeiting has even been exacerbating in wine industry and global supply chain. There has been a number of anti-counterfeiting approaches which have been proposed and adopted utilizing different authentication technologies, in response to growing threats of counterfeiting to wine industry. The proposed NFC-Enabled Anti-Counterfeiting System (NAS) is developed for luxury-good industry such as wine industry, aiming at upholding provenance and authenticity of wine products from counterfeits via the product pedigree, transaction records and supply chain integrity maintained along the supply chain. Consumers can therefore safeguard their stake by authenticating a specific wine product with their NFC-enabled smartphones before purchasing at the retail points. NAS utilizes Near-field Communication (NFC), which has emerged as a promising technology and communication protocol for developing innovative alternatives, to facilitate the wine record processing of wine products and in turn combat wine and spirit counterfeiting. The integrated NAS is consisted of a wide range of hardware and software components, and the best combination of settings, parameters and deployments will therefore be identified. Other possible implementation issues, such as tag selection, tag programming and encryption, setup of back-end database servers and the design of NFC mobile application will also be discussed in this project. The critical design of NAS is vital not only to the key of product anti-counterfeiting of wine industry, but also to the strong foundation for other innovative supply chain solutions, such as the NFC-enabled purchasing system, developed on top of NAS with improved and integrated anti-counterfeiting functionalities.

 Taxonomic synonym: Thorea siamensis Kumano & Traichaiyaporn sensu Suseela & Toppo 2015, p. 138, PL.2, figs 11–13.
 Distribution in India: Uttar Pradesh (Lucknow, Sai River, Mar, Apr., growing at depth of 1–2.5 ft, attached to submerged stones moderately flowing, clear waters).
 Notes: Based on molecular sequences of the rbc L, the barcode region of cox 1, and morphological data, the Indian specimens were described as a new species. The cox 1 barcode sequence had 90.4–90.8% identity with Thorea sp. from Australia and Thorea hispida from Hawaii and China. Based on rbc L sequences, the Indian specimen was positioned in a major clade with high support (>95 bootstrap and 0.95 posterior probability) containing two other species: T. okadae from Japan and T. hispida from the continental USA, Hawaii, the UK, and China. In the light of molecular sequences available for T. indica, it would be worthwhile to study and compare data on records of “ T. hispida ” and “ T. ramosissima ” from other places like Andaman & Nicobar Islands, Ladakh and Bareilly, Uttar Pradesh in India to confirm the number of species present on the Indian sub-continent. Necchi et al. (2015) in their morphological and molecular studies on Thorea plants collected from Sai river in Uttar Pradesh concluded that “the report of T. siamensis by Suseela & Toppo (2015) from the same locality as T. indica has no morphological basis, either in comparison with the original description (Traichaiyaporn et al. 2008) or data from that study”.

On the convective overstability in protoplanetary discs

Year: 2015
Subjects: subject: Earth and Planetary Astrophysics (astro-ph.EP)
subject: FOS: Physical sciences

description: This paper explores the driving of low-level hydrodynamical activity in protoplanetary-disc dead zones. A small adverse radial entropy gradient, ordinarily stabilised by rotation, excites oscillatory convection (`convective overstability') when thermal diffusion, or cooling, is neither too strong nor too weak. I revisit the linear theory of the instability, discuss its prevalence in protoplanetary discs, and show that unstable modes are exact nonlinear solutions in the local Boussinesq limit. Overstable modes cannot grow indefinitely, however, as they are subject to a secondary parametric instability that limits their amplitudes to relatively low levels. If parasites set the saturation level of the ensuing turbulence then the convective overstability is probably too weak to drive significant angular momentum transport or to generate vortices. But I also discuss an alternative, and far more vigorous, saturation route that generates radial `layers' or `zonal flows' (witnessed also in semiconvection). Numerical simulations are required to determine which outcome is favoured in realistic discs, and consequently how important the instability is for disc dynamics.

History

description: With the growth of the digital humanities and historical GIS technologies, scholars have begun to build national and urban databases of census and other records in order to trace the changes in boundaries over time and thus simplify the study of historical change. Because a project to digitize U.S. census enumeration district maps would require time, funding, and staff that most institutions do not have, the most sensible way to create such a database is through crowdsourcing. Other crowdsourced projects, both geographical and non-geographical, have succeeded owing to their creative design and competitive focus as well as the usability of the tools they provide to their volunteer users. Upon review of other crowdsourced mapping projects, recommendations are given for the creation of a GIS database for U.S. census enumeration district maps.
Subdiffusion, Anomalous Diffusion and Propagation of a Particle Moving in Random and Periodic Media

description: We investigate the motion of a single particle moving on a two-dimensional square lattice whose sites are occupied by right and left rotators. These left and right rotators deterministically rotate the particle's velocity to the right or left, respectively and \emph{flip} orientation from right to left or from left to right after scattering the particle. We study three types of configurations of left and right rotators, which we think of as types of media, through with the particle moves. These are completely random (CR), random periodic (RP), and completely periodic (CP) configurations. For CR configurations the particle's dynamics depends on the ratio $r$ of right to left scatterers in the following way. For small $r\simeq0$, when the configuration is nearly homogeneous, the particle subdiffuses with an exponent of 2/3, similar to the diffusion of a macromolecule in a crowded environment. Also, the particle's trajectory has a fractal dimension of $d_f\simeq4/3$, comparable to that of a self-avoiding walk. As the ratio increases to $r\simeq 1$, the particle's dynamics transitions from subdiffusion to anomalous diffusion with a fractal dimension of $d_f\simeq 7/4$, similar to that of a percolating cluster in 2-d. In RP configurations, which are more structured than CR configurations but also randomly generated, we find that the particle has the same statistic as in the CR case. In contrast, CP configurations, which are highly structured, typically will cause the particle to go through a transient stage of subdiffusion, which then abruptly changes to propagation. Interestingly, the subdiffusive stage has an exponent of approximately 2/3 and a fractal dimension of $d_f\simeq4/3$, similar to the case of CR and RP configurations for small $r$.

Measurement of the production cross section of three isolated photons in $pp$ collisions at $\sqrt{s}$ = 8 TeV using the ATLAS detector
Creators: name: ATLAS Collaboration
Publisher: name: Deutsches Elektronen-Synchrotron, DESY, Hamburg
Year: 2017

description: A measurement of the production of three isolated photons in proton--proton collisions at a centre-of-mass energy $\sqrt{s}$ = 8 TeV is reported. The results are based on an integrated luminosity of 20.2 fb$^{-1}$ collected with the ATLAS detector at the LHC. The differential cross sections are measured as functions of the transverse energy of each photon, the difference in azimuthal angle and in pseudorapidity between pairs of photons, the invariant mass of pairs of photons, and the invariant mass of the triphoton system. A measurement of the inclusive fiducial cross section is also reported. Next-to-leading-order perturbative QCD predictions are compared to the cross-section measurements. The predictions underestimate themeasurement of the inclusive fiducial cross section and the differential measurements at low photon transverse energies and invariant masses. They provide adequate descriptions of the measurements at high values of the photon transverse energies, invariant mass of pairs of photons, and invariant mass of the triphoton system.
Search for heavy $ZZ$ resonances in the $\ell^+\ell^-\ell^+\ell^-$ and $\ell^+\ell^-\nu\bar\nu$ final states using proton proton collisions at $\sqrt{s}= 13$ TeV with the ATLAS detector
Creators: name: ATLAS Collaboration

Year: 2017

description: A search for heavy resonances decaying into a pair of $Z$ bosons leading to $\ell^+\ell^-\ell^+\ell^-$ and $\ell^+\ell^-\nu\bar\nu$ final states, where $\ell$ stands for either an electron or a muon, is presented. The search uses proton proton collision data at a centre-of-mass energy of 13 TeV corresponding to an integrated luminosity of 36.1 fb$^{-1}$ collected with the ATLAS detector during 2015 and 2016 at the Large Hadron Collider. Different mass ranges for the hypothetical resonances are considered, depending on the final state and model. The different ranges span between 200 GeV and 2000 GeV. The results are interpreted as upper limits on the production cross section of a spin 0 or spin 2 resonance. The upper limits for the spin 0 resonance are translated to exclusion contours in the context of Type I and Type II two-Higgs-doublet models, while those for the spin 2 resonance are used to constrain the Randall Sundrum model with an extra dimension giving rise to spin 2 graviton excitations.

Rare books

description: This study is an examination of one hundred and ten early printed books with imprint
dates prior to 1700 at North Carolina State University in Raleigh, North Carolina. These
books currently lack significant use, in part due to their status as an at least partially
hidden collection. The first portion of this paper examines how the Special Collections
Research Center at NCSU could begin to build an outreach program to encourage greater
use of these items, and touches on themes such as rare books in mathematics and the
sciences, rare books and special collections at land-grant universities, and ways in which
outreach in special collections is changing. The second half is made up of a descriptive
catalogue of the early printed books to aid NCSU staff, researchers, and students in using
the early printed books at N.C. State.
Building versatile bipartite probes for quantum metrology

description: We consider bipartite systems as versatile probes for the estimation of transformations acting locally on one of the subsystems. We investigate what resources are required for the probes to offer a guaranteed level of metrological performance, when the latter is averaged over specific sets of local transformations. We quantify such a performance via the average skew information, a convex quantity which we compute in closed form for bipartite states of arbitrary dimensions, and which is shown to be strongly dependent on the degree of local purity of the probes. Our analysis contrasts and complements the recent series of studies focused on the minimum, rather than the average, performance of bipartite probes in local estimation tasks, which was instead determined by quantum correlations other than entanglement. We provide explicit prescriptions to characterize the most reliable states maximizing the average skew information, and elucidate the role of state purity, separability and correlations in the classification of optimal probes. Our results can help in the identification of useful resources for sensing, estimation and discrimination applications when complete knowledge of the interaction mechanism realizing the local transformation is unavailable, and access to pure entangled probes is technologically limited.

description: Undergraduates are unique in that they are the first generation to have been completely immersed with modern technology and computers almost from their birth. Because members of the Net Generation have grown up with computers and increasing technological obsolescence, their methods for rating the usefulness of information is based on the speed and ease with which data can be accessed. This paper seeks to confirm that the Net Generation of students cares more about fast access to information then providing that information in ways that will be more then transitory. New methods are needed to work with this new generation of patrons who care more about technology, despite its limitations, then anything else at the library.
