description: 7b. Centaurea cataonica subsp. syriaca Negaresh, subsp. nov. (Fig. 20)
 Centaureae cataonicae subsp. cataonicae affinis, caulibus basi ad mediocre ramosis (nec simplicibus), capitulis 10–12-cephalis (nec 4–6- cephalis), pedunculis inferioribus 2–4-cephalis (nec solitaribus), involucro 25–28 mm (nec 32–48 mm) longo, appendicibus valde brunneis ad nigris (nec stramineis vel paululum brunneis) differt.
 Type:— SYRIA. Syrie borealis, Marasch, 1865, Haussknecht s.n. (holotype P!).
Stem branched from near base to median part; capitula 10 to 12, arranged in a raceme, lowest peduncles with 3–4 heads; involucres 25–28 × 25–28 mm; appendages dark brown to blackish; spine 2–6 mm long.
 Etymology:—The specific epithet refers to Syria, where the new subspecies was collected.
 Taxonomic and distribution remarks: — Centaurea cataonica subsp. syriaca is the first record of C. cataonica from Syria. The epithet ‘ Centaurea gigantea ’ was written on the label of Haussknecht’s plant determined by Ch. Haussknecht. But it is clearly different from C. gigantea by having a smaller habit, wider appendages (5–8 mm wide) totally concealing phyllaries, and is more consistent with C. cataonica.
 Chromosome numbers: —Unknown.

description: We report on studying the dynamic evolution of orbital angular momentum (OAM) carrying light in sum frequency generation (SFG). Dynamic evolution of the SFG beam is studied in different cases, in which the two pump beams are either a single OAM mode or OAM superposition mode. For the cases when the two pumps are both in superposition mode, two kinds of spatial patterns and evolution behaviors are observed, one set of spatial pattern is non-diffractive and unchanged with propagating. In addition, SFG of two pump beams with opposite OAM will evolve into a kind of quasi-Gaussian mode. These observations show that the pumps phases are coherently transferred to SFG beam in the conversion process. Our findings give insights to physical picture of OAM light transformation in nonlinear processes, which can be used in OAM mode engineering and de-multiplexing of different OAM modes.

description: This paper is a survey of search engines found on electronic commerce websites. In a time when e-commerce businesses are showing vulnerability, it is important for them to provide customers with a satisfying shopping experience, which includes providing the ability to easily locate products on the website. The research for this study is comprised of a survey of the search capabilities offered to customers on e-commerce sites. The study involved visiting 35 e-commerce websites: five sites in the following seven categories: Computing; Apparel; Books, Music, & Videos; Toys & Games; Health; Flowers; and General Merchandise. The search engine on each site was evaluated and compared against a set of standardized criteria. The results of the study show that companies are successfully employing advanced search features on the their sites. However, in order to truly provide top customer service, e-commerce companies must provide search engines that are flexible sales and that adapt to the needs of customers.

description: We construct candidates for observables in wedge-shaped regions for a class of 1+1-dimensional integrable quantum field theories with bound states whose S-matrix is diagonal, by extending our previous methods for scalar S-matrices. Examples include the Z(N)-Ising models, the A_N-affine Toda field theories and some S-matrices with CDD factors. We show that these candidate operators which are associated with elementary particles commute weakly on a dense domain. For the models with two species of particles, we can take a larger domain of weak commutativity and give an argument for the Reeh-Schlieder property.

description: In recent years, archivists in the United States and abroad have engaged in a process of reevaluation aimed at bringing diverse new voices into archival holdings, which have long been focused on the papers and records of the dominant culture.  One possible source for this documentation is the records of non-profit organizations that are responsive to the needs of under-documented populations.  This national survey-based research of 499 501(c)(3) and 501(c)(4) organizations asks two questions. First, to what extent do non-profit organizations whose work centers on under-documented populations use archival materials in their activism and research? Second, to what extent do these non-profit organizations maintain documentation of their activities, and what intentions do they have for the future of this documentation?

description: The intra-crystalline diffusion of normal alkanes in LTL and ZSM-12 zeolite was experimentally studied via gravimetric measurements performed at different temperatures. A periodic dependence of the diffusion coefficient on the number of carbon atoms in alkane was detected, which is an experimental proof for resonant diffusion. The present observations were described on the base of the existing theory of the resonant diffusion and several important parameters of the alkane-zeolite interaction and zeolite vibrations were obtained. In the considered temperature region the diffusion coefficient follows the Arrhenius law with periodic dependences of the pre-exponential factor and activation energy on the number of carbon atoms in alkanes. A compensation effect of simultaneous increases of the pre-exponential factor and the activation energy was also established.

Copyright law has become a major issue for many universities as students use their schools' high-speed connection to download a variety of copyrighted and non-copyrighted materials. Universities and copyright holders alike have taken a variety of actions to try to reduce violations and complaints on campus; however, these tactics have not served the information need of students. Students who are provided with information on copyright in a centralized location and accessible format are more likely to have a better understanding of the issues involved than students who are not provided with this information.

A Versatile Family of Galactic Wind Models

Year: 2015
Subjects: subject: Astrophysics of Galaxies (astro-ph.GA)
subject: FOS: Physical sciences

description: We present a versatile family of model galactic outflows including non-uniform mass and energy source distributions, a gravitational potential from an extended mass source, and radiative losses. The model easily produces steady-state wind solutions for a range of mass-loading factors, energy-loading factors, galaxy mass and galaxy radius. We find that, with radiative losses included, highly mass-loaded winds must be driven at high central temperatures, whereas low mass-loaded winds can be driven at low temperatures just above the peak of the cooling curve, meaning radiative losses can drastically affect the wind solution even for low mass-loading factors. By including radiative losses, we are able to show that subsonic flows can be ignored as a possible mechanism for expelling mass and energy from a galaxy compared to the more efficient transonic solutions. Specifically, the transonic solutions with low mass-loading and high energy-loading are the most efficient. Our model also produces low-temperature, high-velocity winds that could explain the prevalence of low-temperature material in observed outflows. Finally, we show that our model, unlike the well-known Chevalier & Clegg (1985) model, can reproduce the observed linear relationship between wind X-ray luminosity and star formation rate (SFR) over a large range of SFR from $1-1000$ M$_{\odot}$/yr assuming the wind mass-loading factor is higher for low-mass, and hence, low-SFR galaxies. We also constrain the allowed mass-loading factors that can fit the observed X-ray luminosity vs. SFR trend, further suggesting an inverse relationship between mass-loading and SFR as explored in advanced numerical simulations.

Academic libraries--United States

description: This study collected disaster plans from a systematic sample of twenty-seven libraries at small, liberal arts colleges chosen from the Carnegie Classification of Institutions of Higher Education. Ten of the twenty-seven college libraries that were contacted provided written disaster plans. A list of seventeen requisite criteria constituting a well-designed disaster plan was formed, and the contents in each of the plans were analyzed to see if they included or excluded each of the criterion. It was found that two of the seventeen criteria were met in all of the plans, while another two of the criteria were mentioned in fifty-percent of the plans. The remaining results all fall somewhere in between those two percentages. Previous studies had indicated that 20% of academic libraries have written disaster plans in place. Thirty-seven percentage of the libraries contacted in this study had written disaster plans, and their plans were very likely to include some of the most important elements of a library disaster plan.

description: We introduce a combination of coherent states as variational test functions for the atomic and radiation sectors to describe a system of Na three- level atoms interacting with a one-mode quantised electromagnetic field, with and without the rotating wave approximation, which preserves the symmetry presented by the Hamiltonian. These provide us with the possibility of finding analytical solutions for the ground and first excited states. We study the properties of these solutions for the V-configuration in the double resonance condition, and calculate the expectation values of the number of photons, the atomic populations, the total number of excitations, and their corresponding fluctuations. We also calculate the photon number distribution and the linear entropy of the reduced density matrix to estimate the entanglement between matter and radiation. For the first time, we exhibit analytical expressions for all of these quantities, as well as an analytical description for the phase diagram in parameter space, which distinguishes the normal and collective regions, and which gives us all the quantum phase transitions of the ground state from one region to the other as we vary the interaction parameters (the matter-field coupling constants) of the model, in functional form.

description: Lattice QCD studies on fluctuations and correlations of charm quantum number have established that deconfinement of charm degrees of freedom sets in around the chiral crossover temperature, $T_c$, i.e. charm degrees of freedom carrying fractional baryonic charge start to appear. By reexamining those same lattice QCD data we show that, in addition to the contributions from quark-like excitations, the partial pressure of charm degrees of freedom may still contain significant contributions from open-charm meson and baryon-like excitations associated with integral baryonic charges for temperatures up to $1.2~ T_c$. Charm quark-quasiparticles become the dominant degrees of freedom for temperatures $T>1.2~ T_c$.

description: The recent Open Government Initiative represents an unprecedented commitment to
make the U.S. government more transparent, collaborative, and participatory. As the
President recently suggested, "Proper records management is the backbone of open
government." This paper explores the interface of Open Government and records
management, and examines some of the challenges and opportunities it engenders. Its
central thesis proposes the Open Government movement may provide an opportunity for
improved recordkeeping by shining a light on long-standing deficiencies. While federal
agencies have been mandated to comply with specific policy provisions, there is a clear
need to reform the recordkeeping practices of government agencies to preserve our
nation's valuable documentary history, and ensure transparent and accountable
governance.
Measurement of transverse energy-energy correlations in multi-jet events in pp collisions at $\sqrt{s} = 7$ TeV using the ATLAS detector and determination of the strong coupling constant $\alpha_{\mathrm{s}}(m_Z)$
Creators: name: ATLAS Collaboration
Publisher: name: Deutsches Elektronen-Synchrotron, DESY, Hamburg
Year: 2015

description: High transverse momentum jets produced in pp collisions at a centre of mass energy of 7 TeV are used to measure the transverse energy-energy correlation function and its associated azimuthal asymmetry. The data were recorded with the ATLAS detector at the LHC in the year 2011 and correspond to an integrated luminosity of 158 $\mathrm{pb}^{-1}$. The selection criteria demand the average transverse momentum of the two leading jets in an event to be larger than 250 GeV. The data at detector level are well described by Monte Carlo event generators. They are unfolded to the particle level and compared with theoretical calculations at next-to-leading-order accuracy. The agreement between data and theory is good and provides a precision test of perturbative Quantum Chromodynamics at large momentum transfers. From this comparison, the strong coupling constant given at the $Z$ boson mass is determined to be $\alpha_{\mathrm{s}}(m_Z) = 0.1173 \pm 0.0010 \mbox{ (exp.) }^{+0.0065}_{-0.0026} \mbox{ (theo.)}$.

description: In previous work it was shown that if certain series based on sums over primes of non-principal Dirichlet characters have a conjectured random walk behavior, then the Euler product formula for its $L$-function is valid to the right of the critical line $\Re (s) > \tfrac{1}{2}$, and the Riemann Hypothesis for this class of $L$-functions follows. Building on this work, here we propose how to extend this line of reasoning to the Riemann zeta function and other principal Dirichlet $L$-functions. We apply these results to the study of the argument of the zeta function. In another application, we define and study a 1-point correlation function of the Riemann zeros, which leads to the construction of a probabilistic model for them. Based on these results we describe a new algorithm for computing very high Riemann zeros, and we calculate the googol-th zero, namely $10^{100}$-th zero to over 100 digits, far beyond what is currently known.

description: As global populations rise, the need for sustainable food security and waste reduction solutions becomes crucial. Antimicrobial food packaging presents a strategic defence against spoilage and pathogens and has the potential to minimise foodborne illnesses and global food losses. Essential oils (EOs), known for their inherent antioxidant and antimicrobial properties, are utilised as natural additives in active food packaging materials. These oils, rich in terpenes and hydrocarbons, are promising for food longevity but face challenges like reduced effectiveness in packaging films, highlighting the necessity for nanoengineered solutions to improve their stability and function in polymer matrices. This article aims to review recent work on the use of EOs incorporated in active food packaging. The focus is on the use of nanotechnology to enhance the antimicrobial efficacy of plant-derived essential oils as preservatives. This article illustrates the nanoscale interactions among essential oils, polymers and food substances, aiming to elucidate how technologies such as nanoencapsulation, nanoemulsions and nanocomposites enhance antibacterial and antioxidant performance while improving packaging structural integrity.

description: We investigate the scalar sector in an extension of the Minimal Supersymmetric Standard Model (MSSM) containing a $SU(2)$ Higgs triplet of zero hypercharge and a gauge singlet beside the $SU(2)$ scalar doublets. In particular, we focus on a scenario of this model which allows a light pseudoscalar and/or a scalar below $100$ GeV, consistent with the most recent data from the LHC and the earlier data from the LEP experiments. We analyze the exotic decay of the discovered Higgs $(h_{125})$ into two light (hidden) Higgs bosons present in the extension. The latter are allowed by the uncertainties in the Higgs decay $h_{125}\to WW^*$, $h_{125}\to ZZ^*$ and $h_{125}\to γγ$. The study of the parameter space for such additional scalars/pseudoscalars decay of the Higgs is performed in the gluon fusion channel. The extra hidden Higgs bosons of the enlarged scalar sector, if they exist, will then decay into lighter fermion paris, i.e., $b\bar{b}$, $τ\barτ$ and $μ\barμ$ via the mixing with the doublets. A detailed simulation using PYTHIA of the $2b+2τ$, $\geq 3τ$, $2b+2μ$ and $2τ+2μ$ final states is presented. From our analysis we conclude that, depending on the selected benchmark points, such decay modes can be explored with an integrated luminosity of 25 fb$^{-1}$ at the LHC at a center of mass energy of 13 TeV.

description: Supernova remnants (SNRs) are the most attractive candidates for the acceleration sites of Galactic cosmic rays. We report the detection of GeV $γ$-ray emission with the Pass 8 events recorded by Fermi Large Area Telescope (Fermi-LAT) in the vicinity of the shell type SNR CTB 37B that is likely associated with the TeV $γ-$ray source HESS J1713-381. The photon spectrum of CTB 37B is consistent with a power-law with an index of $1.89\pm0.08$ in the energy range of $0.5-500$ GeV, and the measured flux connects smoothly with that of HESS J1713-381 at a few hundred GeV. No significant spatial extension and time variation are detected. The multi-wavelength data can be well fitted with either a leptonic model or a hadronic one. However, parameters of both models suggest more efficient particle acceleration than typical SNRs. Meanwhile, the X-ray and $γ$-ray spectral properties of CTB 37B show that it is an interesting source bridging young SNRs dominated by non-thermal emission and old SNRs interacting with molecular clouds.

description: The Southern Historical Collection at the University of North Carolina at Chapel Hill is one of the premier archival repositories for primary documents about the American South. Its founder, J. G. de Roulhac Hamilton, a professor of history at the university, is remembered for his rambles across the South from the 1920s through 1940s, in search of historical documents. Too often, Hamilton's work is thought of as a solitary effort. In reality, the creation of the collection could not have been accomplished without support. This paper considers Hamilton and the Southern Historical Collection from the perspectives of his own family history and education; the supportive environment found at UNC; and the interactions Hamilton had with donors, the press, historians, and archivists. All of these elements fostered the growth of the Southern Historical Collection and, when seen together, they provide a more complex view of the both the founder and the collection.

description: In this Letter, we report on quantitative measurements of the absolute near-field mediated heat flux between a gold coated near-field scanning thermal microscope (NSThM) tip and a planar gold sample at nanometer distances of 0.2 nm- 7 nm. We find an extraordinary large heat flux which is more than five orders of magnitude larger than black-body radiation and four orders of magnitude larger than the values predicted by conventional theory of fluctuational electrodynamics. Additionally, we compare our data with different theories of phonon tunneling which might explain a drastically increased heat flux, but are found not to be able to reproduce the distance dependence observed in our experiment. The findings demand modified or even new models of heat transfer across vacuum gaps at nanometer distances.
Strong gauging or decoupling ghost matter

Publisher: name: arXiv
Year: 2015
Subjects: subject: High Energy Physics - Theory (hep-th)

description: Gauging extra matter is a common way to couple two CFTs discontinuously. We may consider gauging matter by strongly coupled gauge theories at criticality rather than by weakly coupled (asymptotic free) gauge theories. It often triggers relevant deformations and possibly leads to a non-trivial fixed point. In many examples such as the IR limit of SQCDs (and their variants), the relevant RG flow induced by this strong gauging makes the total central charge $a$ increase rather than decrease compared with the sum of the original decoupled CFTs. The dilaton effective field theory argument given by Komargodski and Schwimmer does not apply because strong gauging is not a simple deformation by operators in the original two decoupled CFTs and it may not be UV complete. When the added matter is vector-like, one may emulate strong gauging in a UV completed manner by decoupling of ghost matter. While the UV completed description makes the dilaton effective field theory argument possible, due to the non-unitarity, we cannot conclude the positivity of the central charge difference in accordance with the observations in various examples that show the contrary.

description: There is a common need in astroparticle experiments such as direct dark matter detection, 0ν\b{eta}\b{eta} (double beta decay without emission of neutrinos) and Coherent Neutrino Nucleus Scattering experiments for light detectors with a very low energy threshold. By employing the Neganov-Luke Effect, the thermal signal of particle interactions in a semiconductor absorber operated at cryogenic temperatures, can be amplified by drifting the photogenerated electrons and holes in an electric field. This technology is not used in current experiments, in particular because of a reduction of the signal amplitude with time which is due to trapping of the charges within the absorber. We present here the first results of a novel type of Neganov-Luke Effect detector with an electric field configuration designed to improve the charge collection within the semiconductor.

Sustainability and Social Impact Perception: A Comparative Study of Two State Literary Festival Organizational Models
Creators: name: Branscome, Anna M.
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2009
Subjects: Cultural activities
Library special events

description: This study describes a questionnaire survey of the directors of two state
literary festival models, the “distributive model” as illustrated by
Georgia’s system, and the “centralized model” as exemplified by that of
North Carolina. The intent of this study was to compare and contrast
the two models in terms of two critical variables, sustainability and
positive social impact, and to begin to establish a research base for
further exploration.
Although a low and unbalanced return rate of the surveys precluded a
comparative analysis, a descriptive analysis of the responses and
supplementary material suggests the strengths of the distributive model
include avoiding resource exhaustion, reaching a wider and less
culturally privileged audience at lower cost, and reinforcement of
community identity and pride; the centralized model’s strongest points
appeared to be unity of vision and the ability to tap a broad range of
authors as well as a large audience.

Interior of Black Holes and Information Recovery

description: We analyze time evolution of a spherically symmetric collapsing matter from a point of view that black holes evaporate by nature. We first consider a spherical thin shell that falls in the metric of an evaporating Schwarzschild black hole of which the radius $a(t)$ decreases in time. The important point is that the shell can never reach $a(t)$ but it approaches $a(t)-a(t)\frac{d a(t)}{d t}$. This situation holds at any radius because the motion of a shell in a spherically symmetric system is not affected by the outside. In this way, we find that the collapsing matter evaporates without forming a horizon. Nevertheless, a Hawking-like radiation is created in the metric, and the object looks the same as a conventional black hole from the outside. We then discuss how the information of the matter is recovered. We also consider a black hole that is adiabatically grown in the heat bath and obtain the interior metric. We show that it is the self-consistent solution of $G_{μν}=8πG \langle T_{μν} \rangle$ and that the four-dimensional Weyl anomaly induces the radiation and a strong angular pressure. Finally, we analyze the internal structures of the charged and the slowly rotating black holes.

Type I and Type II Bayesian Methods for Sparse Signal Recovery using Scale Mixtures

Publisher: name: arXiv
Year: 2015
Subjects: subject: Machine Learning (cs.LG)

description: In this paper, we propose a generalized scale mixture family of distributions, namely the Power Exponential Scale Mixture (PESM) family, to model the sparsity inducing priors currently in use for sparse signal recovery (SSR). We show that the successful and popular methods such as LASSO, Reweighted $\ell_1$ and Reweighted $\ell_2$ methods can be formulated in an unified manner in a maximum a posteriori (MAP) or Type I Bayesian framework using an appropriate member of the PESM family as the sparsity inducing prior. In addition, exploiting the natural hierarchical framework induced by the PESM family, we utilize these priors in a Type II framework and develop the corresponding EM based estimation algorithms. Some insight into the differences between Type I and Type II methods is provided and of particular interest in the algorithmic development is the Type II variant of the popular and successful reweighted $\ell_1$ method. Extensive empirical results are provided and they show that the Type II methods exhibit better support recovery than the corresponding Type I methods.

Report on "Touchscreen use in early childhood"
Creators: name: Cristia, Alejandrina
name: Seidl, Amanda
Publisher: name: Open Science Framework
Year: 2022

description: Touchscreens are increasingly prevalent, and anecdotal evidence suggests that young children are very drawn towards them. Yet there is little data regarding how infants use them and how use of such technologies might impact infant development. We addressed these questions through 3 complementary approaches. First, a brief online questionnaire queried over 500 French parents of infants between 5 and 40 months of age on their young child's use of touchscreen technology. Second, 12 infants aged 18 to 36 months and with varying degrees of previous experience with touchscreen technology were observed during a single play session in their homes. Finally, a tablet was provided to the families of 9 infants aged 18 to 37 months, to be used over a one- or two-week period. Ecological measures of communication were gathered before and after this use. All of these data were interrogated through quantitative and qualitative analyses. Results suggest that, among respondent families, the use of touchscreens is widespread in early childhood, with clear developmental trends for certain types of interactive gestures. In most cases, even a brief exposure sufficed to enable infants to gain some autonomy in touchscreen use. Infants were interested in a range of activities, with longer exposures tending to result in shorter play time for familiar activities. No negative effects were observed after the short-term intervention. These results contribute to the investigation of the effects of touchscreen use on early development and suggest a number of considerations that should help improve the design of applications geared towards toddlers, particularly for scientific purposes.
Scheduling Information System: the Design and Development of an Online Database for Tracking Scheduling Information

description: This paper describes the design and development of a Web-based scheduling information system. This particular system is intended to allow workers to enter the hours they would like to request to work so that the scheduler can query the database to see who is available to work on which days in order to make the schedule. The workers are able to query the database as well, so that they can see how many other people have requested the days they plan to request for. For data input, the proposed system presents Web-based HTML forms that can be accessed from any Web browser; the system stores the collected information in a MySQL database. PHP scripting language is used to link the HTML forms and the MySQL database; it constructs SQL insert statements to enter data into the database, and constructs queries to extract information from the database.
