description: After growing successfully TaP single crystal, we measured its longitudinal resistivity (rhoxx) and Hall resistivity (rhoyx) at magnetic fields up to 9T in the temperature range of 2-300K. It was found that at 2K its magnetoresistivity (MR) reaches to 328000 percent, at 300K to 176 percent at 8T, and both do not appear saturation. We confirmed that TaP is indeed a low carrier concentration, hole-electron compensated semimetal, with a high mobility of hole muh=371000 cm2V-1s-1, and found that a magnetic-field-induced metal-insulator transition occurs at room temperature. Remarkably, as a magnetic field (H) is applied in parallel to the electric field (E), the negative MR due to chiral anomaly is observed, and reaches to -3000 percent at 9T without any signature of saturation, too, which distinguishes with other Weyl semimetals (WSMs). The analysis on the Shubnikov-de Haas (SdH) oscillations superimposing on the MR reveals that a nontrivial Berry phase with strong offset of 0.3958 realizes in TaP, which is the characteristic feature of the charge carriers enclosing a Weyl nodes. These results indicate that TaP is a promising candidate not only for revealing fundamental physics of the WSM state but also for some novel applications.

Interface usability

description: The Plant Information Center (PIC) database contains images of plant specimens and corresponding metadata and was designed to facilitate plant identification. While operational since Fall 2000, there has been little research on the overall design and the effectiveness of the interface. This investigation was an exploratory study that evaluated user perceptions of the PIC database with an emphasis on the interface. A test instrument containing questions and tasks was administered to sixteen undergraduate botany students from the University of North Carolina during the Spring 2001 semester. Responses to the questions were mainly positive. Eighty percent (80%) of the participants knew they were searching a database and ten of fifteen participants (66.6%) viewed the database in a positive manner. Although responses to the questions were supportive of the database, user comments suggest that improvements could be implemented to make the database, particularly the interface, more user friendly.

description: We present three-dimensional simulations of the dynamics of binary neutron star (BNS) mergers from the late stage of the inspiral process up to $\sim 20$ ms after the system has merged, either to form a hyper-massive neutron star (NS) or a rotating black hole (BH). We investigate five equal-mass models of total gravitational mass $2.207$, $2.373$, $2.537$, $2.697$ and $2.854 M_\odot$, respectively, and four unequal mass models with $M_{\mathrm{ADM}}\simeq 2.53\ M_\odot$ and $q\simeq 0.94$, $0.88$, $0.82$, and $0.77$ (where $q = M^{(1)}/M^{(2)}$ is the mass ratio). We use a semi-realistic equation of state (EOS) namely, the seven-segment piece-wise polytropic SLyPP with a thermal component given by $Γ_{th} = 1.8$. We have also compared the resulting dynamics (for one model) using both, the BSSN-NOK and CCZ4 methods for the evolution of the gravitational sector, and also different reconstruction methods for the matter sector, namely PPM, WENO and MP5. Our results show agreement and high resolution, but superiority of BSSN-NOK supplemented by WENO reconstruction at lower resolutions. One of the important characteristics of the present investigation is that, for the first time, this has been done using only publicly available open source software, in particular, the Einstein Toolkit code deployed for the dynamical evolution and the LORENE code for the generation of the initial models. All of the source code and parameters used for the simulations have been made publicly available. This not only makes it possible to re-run and re-analyze our data; it also enables others to directly build upon this work for future research.

description: Tensorial non-standard neutrino interactions are studied through a combined analysis of nuclear structure calculations and a sensitivity $χ^2$-type of neutrino events expected to be measured at the COHERENT experiment, recently planned to operate at the Spallation Neutron Source (Oak Ridge). Potential sizeable predictions on transition neutrino magnetic moments and other electromagnetic parameters, such as neutrino milli-charges, are also addressed. The non-standard neutrino-nucleus processes, explored from nuclear physics perspectives within the context of quasi-particle random phase approximation, are exploited in order to estimate the expected number of events originating from vector and tensor exotic interactions for the case of reactor neutrinos, studied with TEXONO and GEMMA neutrino detectors.

description: In this paper, the deployment of an unmanned aerial vehicle (UAV) as a flying base station used to provide on the fly wireless communications to a given geographical area is analyzed. In particular, the co-existence between the UAV, that is transmitting data in the downlink, and an underlaid device-todevice (D2D) communication network is considered. For this model, a tractable analytical framework for the coverage and rate analysis is derived. Two scenarios are considered: a static UAV and a mobile UAV. In the first scenario, the average coverage probability and the system sum-rate for the users in the area are derived as a function of the UAV altitude and the number of D2D users. In the second scenario, using the disk covering problem, the minimum number of stop points that the UAV needs to visit in order to completely cover the area is computed. Furthermore, considering multiple retransmissions for the UAV and D2D users, the overall outage probability of the D2D users is derived. Simulation and analytical results show that, depending on the density of D2D users, optimal values for the UAV altitude exist for which the system sum-rate and the coverage probability are maximized. Moreover, our results also show that, by enabling the UAV to intelligently move over the target area, the total required transmit power of UAV while covering the entire area, is minimized. Finally, in order to provide a full coverage for the area of interest, the tradeoff between the coverage and delay, in terms of the number of stop points, is discussed.

description: The strong coupling constant is one of the fundamental parameters of the standard model of particle physics. In this review I will briefly summarise the theoretical framework, within which the strong coupling constant is defined and how it is connected to measurable observables. Then I will give an historical overview of its experimental determinations and discuss the current status and world average value. Among the many different techniques used to determine this coupling constant in the context of quantum chromodynamics, I will focus in particular on a number of measurements carried out at the Large Electron Positron Collider (LEP) and the Large Hadron Collider (LHC) at CERN.

description: Large-scale interacting human activities underlie all social and economic phenomena, but quantitative understanding of regular patterns and mechanism is very challenging and still rare. Self-organized online collaborative activities with precise record of event timing provide unprecedented opportunity. Our empirical analysis of the history of millions of updates in Wikipedia shows a universal double power-law distribution of time intervals between consecutive updates of an article. We then propose a generic model to unfold collaborative human activities into three modules: (i) individual behavior characterized by Poissonian initiation of an action, (ii) human interaction captured by a cascading response to others with a power-law waiting time, and (iii) population growth due to increasing number of interacting individuals. This unfolding allows us to obtain analytical formula that is fully supported by the universal patterns in empirical data. Our modeling approaches reveal "simplicity" beyond complex interacting human activities.

description: When compared to the policies and procedures that have been developed for their non-digital counterparts, the field of digital preservation is still in its infancy. This lack of established procedures and standards does not detract from the importance of ensuring the preservation of digital collections. One aspect that lacks sufficient research is the role that preservation metadata plays. Preservation metadata is necessary for effective preservation of digital collections. Of equal importance is the ability for this metadata to be interoperable between institutions. If preservation metadata is present, but it cannot be understood by other institutions, its value is greatly diminished. This research seeks to determine the level of use of preservation metadata for digital collections for the 123 members of the Association of Research Libraries. From this determination, this research will also briefly address the role of interoperability for preservation metadata-collecting libraries, and the type of workflows currently being used.

description: This content analysis of six fantasy novels for children aged approximately 8 to 12 discusses the archetypal Hero's Journey and its relation to the gender of the protagonist. These novels were read and analyzed for adherence to or departure from the traditional 17 stages of Joseph Campbell's monomyth, described in The Hero with a Thousand Faces. The focus of the content analysis is whether female protagonists on quests face modified quests and employ stereotypically feminine techniques to overcome obstacles as opposed to their swashbuckling male counterparts. The modifications found in the six novels suggest that heroines rely on empathy rather than strength to complete quests.

Pion-nucleon correlations in finite nuclei in a relativistic framework: effects on the shell structure
Creators: name: Litvinova, Elena
Publisher: name: arXiv
Year: 2015
Subjects: subject: Nuclear Theory (nucl-th)
subject: FOS: Physical sciences

description: The relativistic particle-vibration coupling (RPVC) model is extended by the inclusion of spin- and isospin-flip excitation modes into the phonon space, introducing a new mechanism of dynamical interaction between nucleons with different isospin in the nuclear medium. Protons and neutrons exchange by collective modes which are formed by isovector $π$ and $ρ$-mesons, in turn, softened considerably because of coupling to nucleons of the medium. These modes are investigated within the proton-neutron relativistic random phase approximation (pn-RRPA) and relativistic proton-neutron time blocking approximation (pn-RTBA). The appearance of isospin-flip states with sizable transition probabilities at low energies points out that they are likely to couple to the single-particle degrees of freedom and, in addition to isoscalar low-lying phonons, to modify their spectroscopic characteristics. Such a coupling is quantified for the shell structure of $^{100,132}$Sn and found significant for the location of the dominant single-particle states.

description: As few real systems comprise indistinguishable units, diversity is a hallmark of nature. Diversity among interacting units shapes properties of collective behavior such as synchronization and information transmission. However, the benefits of diversity on information processing at the edge of a phase transition, ordinarily assumed to emerge from identical elements, remain largely unexplored. Analyzing a general model of excitable systems with heterogeneous excitability, we find that diversity can greatly enhance optimal performance (by two orders of magnitude) when distinguishing incoming inputs. Heterogeneous systems possess a subset of specialized elements whose capability greatly exceeds that of the nonspecialized elements. Nonetheless, the behavior of the whole network can outperform all subgroups. We also find that diversity can yield multiple percolation, with performance optimized at tricriticality. Our results are robust in specific and more realistic neuronal systems comprising a combination of excitatory and inhibitory units, and indicate that diversity-induced amplification can be harnessed by neuronal systems for evaluating stimulus intensities.

description: This paper discusses an assessment case study conducted at the Ullman Classics  Departmental Library at the University of North Carolina at Chapel Hill. The aim of the  project was to discover the effectiveness of independent, departmental libraries at serving  their primary faculty, graduate student, and undergraduate populations. The research was  conducted using mixed methods. Usage statistics from the main UNC library system  were analyzed and compared with user-reported usage information regarding similar  items in the Ullman Library collection. Semi-structured interviews were conducted with  eight representative members of the population group to provide a context for the  statistical usage data. The data revealed that elements including convenience of access,  continuity of the departmental community across generations, and the departmental  library as a physical information commons all contributed to a more positive library  experience as an independent, isolated collection than would be gained from integration  with the main library system.

description: This article examines the operational research conducted by the Canadian Corps Gas Services and the Canadian Machine Gun Corps during the First World War. It develops the initial inquiry completed by scholars J.S. Finan and W.J. Hurley and finds that the staff officers of these two specialised Corps conducted operational research with varying degrees of rigour. While none of them ever used the term ‘operational research’ to describe their work, they were undoubtedly its practitioners through their innovation, trials, experimentation, and subsequent dissemination of knowledge. This article offers a new interpretation of their adoption of a new scientific approach to operations and learning within the Canadian Corps during the First World War.

description: This study examines copyright concerns of syndicated materials within digital copies of college student newspapers. A sample of 100 colleges were inspected to determine if archived issues of the student newspapers were available online and if so, did the newspapers contain syndicated material. The collection was further examined to establish if any effort was made to exclude the copyrighted material or if an explanation was provided for the inclusion of the material. This study shows approximately one third of the student newspapers that are available online contain syndicated material and only twenty percent made an effort to reduce copyright infringement or document fair use. Considering these findings and the prevalence of digitizing college student newspapers, more research is needed in this field.

description: In this paper we mainly investigate the Cauchy problem of some Camassa-Holm type systems. By constructing a new auxiliary function, we present a generalized Ovsyannikov theorem. By using this theorem and the basic properties of Sobolev-Gevrey spaces, we prove the Gevrey regularity and analyticity of these systems. Moreover, we obtain a lower bound of the lifespan and the continuity of the data-to-solution map.

description: In a collinear antiferromagnet with easy-axis anisotropy, symmetry dictates that the spin wave modes must be doubly degenerate. Theses two modes, distinguished by their opposite polarization and available only in antiferromagnets, give rise to a novel degree of freedom to encode and process information. We show that the spin wave polarization can be manipulated by an electric field induced Dzyaloshinskii-Moriya interaction and magnetic anisotropy. We propose a prototype spin wave field-effect transistor which realizes a gate-tunable magnonic analog of the Faraday effect, and demonstrate its application in THz signal modulation. Our findings open up the exciting possibility of digital data processing utilizing antiferromagnetic spin waves and enable the direct projection of optical computing concepts onto the mesoscopic scale.

description: Aims. We present the first orbital solution for the O-type supergiant star HD 74194, which is the optical counterpart of the supergiant fast X-ray transient IGR J08408-4503. Methods. We measured the radial velocities in the optical spectrum of HD 74194, and we determined the orbital solution for the first time. We also analysed the complex Hα profile. Results. HD 74194 is a binary system composed of an O-type supergiant and a compact object in a short-period ($P=9.5436\pm0.0002$ d) and high-eccentricity ($e=0.63\pm0.03$) orbit. The equivalent width of the Hα line is not modulated entirely with the orbital period, but seems to vary in a superorbital period ($P=285\pm10$ d) nearly 30 times longer than the orbital one.

Needs assessment

description: Digital Humanities scholars have not traditionally been focused on the overall usability of their online projects or how users perceive these resources. As a result, Digital Humanities is in danger of leaving out users voices entirely. This presents an opportunity for libraries, as partners, to add value to digital scholarship by assessing the extent to which Digital Humanities resources are meeting the needs of its users. The following study is a qualitative user assessment of Project Vox, a Digital Humanities initiative that provides pedagogical and research materials on underrepresented philosophers from the early modern period. Through interviewing six philosophy professors, this user assessment takes into account humanists’ existing workflows, investigates their usage and the usability of the site, and finally examines how they perceive some of Project Vox’s practices and the broader Digital Humanities landscape.
A FWHM-K2 correlation in Black-Hole transients

description: We compare Halpha emission profiles of 12 dynamically confirmed black holes (BHs) and 2 neutron star X-ray transients (SXTs) in quiescence with those of a sample of 43 Cataclysmic Variables (CVs), also quiescent. The full-width-half maximum (FWHM) of the Halpha line in SXTs is tightly correlated with the velocity semi-amplitude of the donor star K2=0.233(13) FWHM. This new correlation, when combined with orbital periods (i.e. through photometric light curves), opens the possibility to estimate compact object mass functions from single integration, low-resolution spectroscopy. On the other hand, CVs above the period gap are found to follow a flatter correlation, a likely consequence of their larger mass ratios. We also find that the FWHM traces the disc velocity at ~42% R_L1, independently of binary mass ratio. In addition, for a given FWHM, BHs tend to have lower EWs than CVs. This might be explained by the fact that CVs must be seen at higher inclinations to mimic the same projected disc velocities as BH SXTs. For the same reason CVs with FWHM>~1500 km/s are mostly eclipsing while none of our sample BHs are. Further, we show that there is a vacant/unoccupied region for CVs in the FWHM-EW plane defined by FWHM > 2568 ( 1 - (9/EW)**2 )**0.5 (km/s). Both the FWHM-K2 correlation and the FWHM-EW plane can be exploited, together with photometric light curves, to efficiently discover quiescent BHs in deep Halpha surveys of the Galactic Plane.

description: We revisit the color-diffusion algorithm [P. C. Aeberhard et al., Phys. Rev. Lett. 108, 095901 (2012)] in nonequilibrium ab initio molecular dynamics (NE-AIMD), and propose a simple efficient approach for the estimation of monovacancy jump rates in crystalline solids at temperatures well below melting. Color-diffusion applied to monovacancy migration entails that one lattice atom (colored-atom) is accelerated toward the neighboring defect-site by an external constant force F. Considering bcc molybdenum between 1000 and 2800 K as a model system, NE-AIMD results show that the colored-atom jump rate k_{NE} increases exponentially with the force intensity F, up to F values far beyond the linear-fitting regime employed previously. Using a simple model, we derive an analytical expression which reproduces the observed k_{NE}(F) dependence on F. Equilibrium rates extrapolated by NE-AIMD results are in excellent agreement with those of unconstrained dynamics. The gain in computational efficiency achieved with our approach increases rapidly with decreasing temperatures, and reaches a factor of four orders of magnitude at the lowest temperature considered in the present study.

No Truth in Numbers: The Effect of the Media Center on the Performance of North Carolina High Schools as Measured by ABC Standards

description: This study examined the effect of school library media collections and circulation on  student achievement in North Carolina high schools. Using data from the North Carolina  Annual Media and Technology Report and the composite scores from the North Carolina  ABC report card, analysis was done to determine if correlations between the two sets of  data using several variables could be established. The data used from the Annual Media  and Technology Report was related to media program collections and circulation and not  to the media specialists themselves or to their programmatic activities. The results  showed no correlation between collection and circulation data and academic performance  as measured by the ABC composite scores. Given the many prior studies correlating  student achievement with strong school library media programs, this study further  suggests that the role of the media specialist is pivotal in creating strong media programs  and improving student achievement.
Coupling Nanomechanical and Chemical Characterization for Evaluating Properties of Small-Scale Moleuclar Crystals

description: Molecular crystals are used in a wide variety of applications, from pharmaceuticals and sweeteners to energetic materials. Understanding their chemical and mechanical properties provides insight into their performance and use. These properties are especially critical for energetic material systems, which may be sensitive to impact and require specific handling and storage practices. The mechanical properties of energetic molecular crystals are typically determined using nanoindentation by measuring elastic modulus, hardness, yield point, and fracture behavior. Reports of the properties and mechanical behavior of as-grown molecular crystals are limited due to the relative difficulty of performing good quality measurements. This work’s contributions include the first known measurements of elastic and plastic properties for crystals of DAAF, CL-20, NTO, ETN, and R-salt. When studying molecular crystalline systems, some important assumptions and behaviors typical to metallic and ionic systems begin to break down. The energetic material diaminoazoxyfurazan (DAAF) exhibits highly irregular mechanical behavior, which is likely explained by a complex combination of chemical and material attributes. This work investigates and compares the irregular mechanical response in DAAF—including high variance in mechanical properties, broad range of load-depth behavior, and non-conforming indentation impression geometries—to other energetic molecular crystals. The yield points (i.e., onset of plasticity) for several energetic materials, whose elastic modulus values range from 9.6 to 25.5 GPa, are also compared to identify the parameters that govern the onset of plasticity. This includes an investigation into yield point dependence on (or independence from) elastic modulus, hardness, near-neighbor spacing, and activation volume. When these materials reach the onset of plasticity, the maximum shear stress in each material ranges from 2-7% of their elastic modulus value. Analysis of the yield behavior in these materials suggests that there is not a strong correlation between yield stress and hardness, thus establishing that the mechanisms governing dislocation nucleation are not controlled by hardness, and vice-versa. By recognizing and accounting for the added complexities associated with inherently non-spherical molecules in a crystal lattice, this work advances the comprehension of mechanical response in molecular crystal systems.

description: Here, we report wafer scale fabrication of densely packed Fe nanostripe-based magnetic thin films on a flexible substrate and their magnetic anisotropy properties. We find that Fe nanostripes exhibit large in-plane uniaxial anisotropy and nearly square hysteresis loops with energy products (BH)max exceeding 3 MGOe at room temperature. High density Fe nanostripes were fabricated on 70 nm flexible polyethylene terephthalate (PET) gratings, which were made by roll-to-roll (R2R) UV nanoimprintlithography technique. Observed large in-plane uniaxial anisotropies along the long dimension of nanostripes are attributed to the shape. Temperature dependent hysteresis measurements confirm that the magnetization reversal is driven by non-coherent rotation reversal processes.
