title: Differences in Motivation for Participation and Attitudes Toward Management Among Rock Climbing Sub Groups: Implications for the Benefits-Based Management Approach
Creators: name: Ackerman, Amy L.
Publisher: name: Old Dominion University Libraries
Year: 2006

description: The purpose of this research was to develop a scale that would measure the motivation for participation of rock climbing subgroups, determine what differences exist among rock climbing subgroups and confirm the Rock Climbers' Attitudes toward Management Scale. Respondents were given an on-site questionnaire at three rock climbing areas in the United States. Respondents identified themselves according to their preferred type of climbing (e.g., traditional climbing, sport climbing, and hybrid climbing) and their preferred mode of climbing (e.g., lead climbing, top roping, and both equally). Exploratory factor analysis identified five factors for the Rock Climbing Motivation Scale: competition, control, escape, sensation seeking, and social. An analysis of variance confirmed there were no significant differences among types of climbers on the Rock Climbers' Motivation Scale or Rock Climbers' Attitudes toward Management Scale, contrary to previously reported findings. Mode of climbing was found to be a significant predicator of frequency of use, years of experience was found to be a significant predictor of frequency of use, and level of climbing ability was found to be a significant predictor of mode of climbing. The results of this study were then applied to the Benefits-Based Management Approach.

description: We consider fractional order optimal control problems in which the dynamic control system involves integer and fractional order derivatives and the terminal time is free. Necessary conditions for a state/control/terminal-time triplet to be optimal are obtained. Situations with constraints present at the end time are also considered. Under appropriate assumptions, it is shown that the obtained necessary optimality conditions become sufficient. Numerical methods to solve the problems are presented, and some computational simulations are discussed in detail.

Simple, broadband, optical spatial cloaking of very large objects

Year: 2013
Subjects: subject: Optics (physics.optics)
subject: FOS: Physical sciences

description: We demonstrate three simple cloaking devices that can hide very large spatial objects over the entire visible spectrum using only passive, off-the-shelf optics. The cloaked region for all of the devices exceeds 10^6 mm3 with the largest exceeding 10^8 mm3. Although uni-directional, these cloaks can hide the cloaked object, even if the object is transversely or self-illuminated. Owing to the small usable solid angle, but simple scaling, these cloaks may be of value in hiding small field-of-view objects such as mid- to high-earth orbit satellites.

description: The worldwide centenary of the 1917 revolution provided the occasion to revisit the question of its place in twentieth-century history, at a time when the country that had long borne aloft the “myth of October”, after much hesitation, and in clear indication of its discomfort, steered clear of any official commemoration. The purpose of this special issue is to look back at the year of commemorations around the world, marked by highly varied events, including academic conferences and art exhibitions. Yet with just a few exceptions, these commemorative events have pushed into the background its political significance for the present. This dossier is based on the contrast with what was feasible before 1989 or 1991. The analysis ranges across several countries where the centenary was celebrated, without being feted in revolutionary terms.

Control of Underwater Vehicles in Inviscid Fluids. I: Irrotational Flows

Year: 2013
Subjects: subject: Analysis of PDEs (math.AP)
subject: FOS: Mathematics

description: In this paper, we investigate the controllability of an underwater vehicle immersed in an infinite volume of an inviscid fluid whose flow is assumed to be irrotational. Taking as control input the flow of the fluid through a part of the boundary of the rigid body, we obtain a finite-dimensional system similar to Kirchhoff laws in which the control input appears through both linear terms (with time derivative) and bilinear terms. Applying Coron's return method, we establish some local controllability results for the position and velocities of the underwater vehicle. Examples with six, four, or only three controls inputs are given for a vehicule with an ellipsoidal shape.

description: Tripleset interlinking is one of the main principles of Linked Data. However, the discovery of existing triplesets relevant to be linked with a new tripleset is a non-trivial task in the publishing process. Without prior knowledge about the entire Web of Data, a data publisher must perform an exploratory search, which demands substantial effort and may become impracticable, with the growth and dissemination of Linked Data. Aiming at alleviating this problem, this paper proposes a recommendation approach for this scenario, using a Social Network perspective. The experimental results show that the proposed approach obtains high levels of recall and reduces in up to 90% the number of triplesets to be further inspected for establishing appropriate links. The final publication is available at Springer via http://dx.doi.org/10.1007/978-3-642-41230-1_13.

description: Signals broadly compatible with light (7-10 GeV) dark matter have been reported in three direct detection experiments: CoGeNT, DAMA/LIBRA, and CDMS-II silicon. These possible signals have been interpreted in the context of spin-independent interactions between the target nuclei and dark matter, although there is tension with null results, particularly from xenon-based experiments. In this paper, we demonstrate that the CoGeNT and CDMS-II silicon results are also compatible assuming a spin-dependent neutron interaction, though this is in tension with xenon-based experiments and PICASSO. The tension with the null results from XENON100 and XENON10 is approximately the same as for the spin-independent coupling. All three experimental signals can be made compatible through a combination of spin-dependent interactions with both the proton and neutron, although such a scenario increases the conflict with the null results of other experiments.

description: On September 14, 2015, the Laser Interferometer Gravitational-Wave Observatory (LIGO) detected a gravitational-wave transient (GW150914); we characterize the properties of the source and its parameters. The data around the time of the event were analyzed coherently across the LIGO network using a suite of accurate waveform models that describe gravitational waves from a compact binary system in general relativity. GW150914 was produced by a nearly equal mass binary black hole of masses 36+5−4M⊙ and 29+4−4M⊙; for each parameter we report the median value and the range of the 90% credible interval. The dimensionless spin magnitude of the more massive black hole is bound to be <0.7 (at 90% probability). The luminosity distance to the source is 410+160−180 Mpc, corresponding to a redshift 0.09+0.03−0.04 assuming standard cosmology. The source location is constrained to an annulus section of 610 deg2, primarily in the southern hemisphere. The binary merges into a black hole of mass 62+4−4M⊙ and spin 0.67+0.05−0.07. This black hole is significantly more massive than any other inferred from electromagnetic observations in the stellar-mass regime.

description: We formulate a model of N_f=4 flavors of relativistic fermion in 2+1d in the presence of a chemical potential mu coupled to two flavor doublets with opposite sign, akin to isopsin chemical potential in QCD. This is argued to be an effective theory for low energy electronic excitations in bilayer graphene, in which an applied voltage between the layers ensures equal populations of particles on one layer and holes on the other. The model is then reformulated on a spacetime lattice using staggered fermions, and in the absence of a sign problem, simulated using an orthodox hybrid Monte Carlo algorithm. With the coupling strength chosen to be close to a quantum critical point believed to exist for N_f

description: A mechanical model has been developed by the authors in order to predict the shear strength of reinforced concrete slabs under concentrated loads close to linear supports. The model takes into account a significant number of variables involved in the phenomenon, such as the clear shear span, the concrete compressive strength, the reinforcement ratio, the effective depth, the load spreading angle, the size effect and the size of the loaded area. It is applicable to simply supported slabs, cantilever slabs and situations with partial restraint to the rotation, such as intermediate supports. It has been validated with a database of 90 shear test in slabs subjected to a single concentrated load in different supporting conditions, yielding results on the safe side and showing low scatter. A parametric analysis of the model is also presented, detailing how the different involved variables affect the shear strength. These results, along with the simplified expressions for the shear strength calculation, provide a useful tool for the assessment of the shear strength of reinforced concrete solid slabs in daily engineering.

description: Reinforced concrete bridge size box culverts (RCBCs), with structure length greater than or equal to 6.1 m (20 ft), are an integral part of the transportation infrastructure. Load rating RCBCs is essential, and the critical component is generally the top slab. The objective of this study is to propose a triage methodology to quickly and conservatively determine the rating factor (RF) for the top slab of a two-cell RCBC. The derivation of the demand equations is illustrated in this manuscript for the top slab and the AASHTO HL-93 live load. The finite element program CANDE is used to evaluate the influence of the cell clear height (H), cell clear span (S), fill height (HF), and the backfill modulus (E) on the demand loads. Multiple regression analyses showed that H had no significant effect on the dead load demands, while H and E had no significant effect to the live load demands. Conservative linear demand equations (LDEs) are presented to calculate the dead and live load demands leading to a quick determination of the RF. LDEs for single and multi-cell culverts can be derived following the LDE procedure outlined herein.

description: The CMS experiment at the Large Hadron Collider has recently presented data on the average transverse momentum of protons, kaons and pions as a function of particle multiplicity. We relate the particle multiplicity to saturation momentum using recently published computations of the interaction radius determined from the theory of the Color Glass Condensate. We show that the pp and the pA experimental data scale in terms of these saturation momenta. Computing transverse momentum spectra for identified particles using Boltzmann-type distributions and relating different associated multiplicities using geometric scaling, these simple distributions reproduce the observed dependence of the mean transverse momentum on particle multiplicities seen in both pp and pA interactions for pions to good accuracy, and to fair agreement for protons and kaons.

The Worldsheet Perspective of T-duality Symmetry in String Theory

Year: 2013
Subjects: subject: High Energy Physics - Theory (hep-th)
subject: FOS: Physical sciences

description: The purpose of this article is to present a pedagogical review of T-dualityin in string theory. The evolution of the closed string is envisaged on the worldsheet in the presence of its massless excitations. The duality symmetry is studied when some of the spacial coordinates are compactified on d-dimensional torus, $T^d$. The known results are reviewed to elucidate that equations of motion for the compact coordinates are $O(d,d)$ covariant, $d$ being the number of compact directions. Next, the vertex operators of excited massive levels are considered in a simple compactification scheme. It is shown that the vertex operators for each massive level can be cast in a T-duality invariant form in such a case. Subsequently, the duality properties of superstring is investigated in the NSR formulation for the massless backgrounds such as graviton and antisymmetric tensor. The worldsheet superfield formulation is found to be very suitable for our purpose. The Hassan-Sen compactification is adopted and it is shown that the worldsheet equations of motion for compact superfields to be very suitable for our purpose. The Hassan-Sen compactification is adopted and it is shown that the worldsheet equations of motion for compact superfields are $O(d,d)$ covariant when the backgrounds are independent of superfields along compact directions. The vertex operators for excited levels are presented in the NS-NS sector and it is shown that they can be cast in T-duality invariant form for the case of Hassan-Sen compactification scheme. An illustrative example is presented to realize our proposal.

description: Torque Teno Virus (TTV) is an "orphan" virus with unclear pathology, though it has been associated with various diseases and co-infections. TTV blood levels may serve as indicators of immune system function and inflammatory disorders. This study examines the relationship between TTV viremia and clinical markers in a cohort of patients with severe to very severe COPD undergoing respiratory rehabilitation.

Methods: We analyzed 102 elderly COPD patients, grouped by TTV viremia levels (< or ≥ 4 log10 copies/mL). The two groups were compared by selected clinical markers, mortality, inflammatory-oxidative parameters (Lymphocyte/Monocyte, Neutrophil/Lymphocyte, and Platelet/Lymphocyte ratios), IL-6 (ELISA assay), and DNA damage (comet assay).

Results: Among the patients, 62.75% had TTV viremia > 4 log10 copies/mL. No association was found between TTV levels and epidemiological and clinical variables investigated. Higher TTV viremia correlated with increased DNA damage, and a significantly lower 5-year survival probability.

description: Bulk-sensitive hard x-ray photoemission spectroscopy (HAXPES) reveals for as-grown epitaxial films of half-metallic ferromagnetic CrO2(100) a pronounced screening feature in the Cr 2p3/2 core level and an asymmetry in the O 1s core level. This gives evidence of a finite, metal-type Fermi edge, which is surprisingly not observed in HAXPES. A spectral weight shift in HAXPES away from the Fermi energy is attributed to single-ion recoil effects due to high energy photoelectrons. In conjunction with inverse PES the intrinsic correlated Mott-Hubbard-type electronic structure is unravelled, yielding an averaged Coulomb correlation energy Uav ~ 3.2 eV.

description: Multiple hazards, such as, earthquake, strong wind, snow, flood-induced scour, tsunami, landslide, rain, blast, explosion, fire outbreak, etc. have caused extensive global devastations to civil structure and infrastructure systems in terms of physical and socio-economic losses. The catastrophic losses are largely due to the complex effects of these multiple hazards, as the existing provisions currently do not address the intriguing effects of multi-hazard. The associated complex and multifaceted effects, hence, warrant urgent attention for establishing new design code provisions to assess new and retrofit existing structures. In this context, this article presents a detailed and comprehensive review about the multi-hazard effects on structures and infrastructures exposed to different natural and manmade hazards. The prevailing global challenges are addressed for consideration of the complex interaction and inter-relation effects under the multiple hazard scenarios. The existing information on multi-hazard analysis is critically synthesized, and the similarities and differences of existing multi-hazard studies along with the future challenges are provided. Moreover, existing assessment techniques for optimal design of structures are discussed, emphasizing the mitigation strategies adopted under the multi-hazard scenarios. Special attention is also focused in developing the scientific knowhow to protect the structures for better performance under a selection of the complex and intriguing multi-hazard scenarios.

description: We present the results of an infrared photometric survey performed with NICS@TNG in the nearby starburst galaxy NGC 4214. We derived accurate integrated JK magnitudes of 10 young massive clusters and compared them with the already available Hubble Space Telescope ultraviolet colors. These clusters are located in the combined ultraviolet-infrared colors planes on well defined sequences, whose shapes allow a precise determination of their age. By means of the comparison with suitable stellar evolution models we estimated ages, metallicities, reddening and masses of these clusters. All the analyzed clusters appear to be younger than log(t/yr)<8.4, moderately metal-rich and slightly less massive than present-day Galactic globular clusters. The derived ages for clusters belonging to the secondary HII star forming complex are significantly larger than those previously estimated in the literature. We also discuss the possibility of using the ultraviolet-infrared color-color diagram to select candidate young massive clusters hosting multiple stellar populations.

description: The challenges and future trends in the development of signal processing tools are being widely used for damage identification in bridges. Therefore, it is important to analyse the vibration signals in order to attain effective damage characterization. In this paper, the non-linear and non-stationary dynamic response of bridges under operational loads is studied. First, the signals are decomposed into intrinsic mode functions (IMF) by a novel Improved Completed Ensemble EMD with Adaptive Noise technique (ICEEMDAN). Hilbert-Huang transform is used to obtain their corresponding Hilbert spectra. The marginal Hilbert spectrum (MHS) of each IMF and the instantaneous phase difference (IPD) are proposed as total damage indicators (DI), in the sense that they are able to detect, localize and quantify damage under transient vibration due to traffic. The methodology was tested in two case studies: (i) a numerical model of a two-span steel bridge (ii) a dynamic test conducted on a real steel arch bridge subjected to a series of artificial damages. The experimental and real case results from the damage indices based on the extracted features demonstrate the robustness and more sensitivity of the novel Improved Completed Ensemble EMD with Adaptive Noise technique (ICEEMDAN) in addressing the damage location.

description: Carbon-enhanced metal poor stars (CEMP) form a significant proportion of the metal-poor stars, their origin is not well understood. Three very metal-poor C-rich turnoff stars were selected from the SDSS survey, observed with the ESO VLT (UVES) to precisely determine the element abundances. In turnoff stars (unlike giants) the carbon abundance has not been affected by mixing with deep layers and is therefore easier to interpret. The analysis was performed with 1D LTE static model atmospheres. When available, non-LTE corrections were applied to the classical LTE abundances. The 3D effects on the CH and CN molecular bands were computed using hydrodynamical simulations of the stellar atmosphere (CO5BOLD) and are found to be very important. To facilitate a comparison with previous results, only 1D abundances are used in the discussion. The abundances (or upper limits) of the elements enable us to place these stars in different CEMP classes. The carbon abundances confirm the existence of a plateau at A(C)= 8.25 for [Fe/H] \geq -3.4. The most metal-poor stars ([Fe/H] < -3.4) have significantly lower carbon abundances, suggesting a lower plateau at A(C) \approx 6.5. Detailed analyses of a larger sample of very low metallicity carbon-rich stars are required to confirm (or refute) this possible second plateau and specify the behavior of the CEMP stars at very low metallicity.

description: Ferropericlase (Mg,Fe)O is a major lower mantle mineral, and studying its properties is a fundamental step toward understanding the Earth's interior. Here, we performed a first-principles investigation on the properties of iron as an isolated impurity in magnesium oxide, which is the condition of ferropericlase under which iron-iron interactions could be neglected. The calculations were carried using the all-electron full-potential linearized augmented plane wave method within the density functional theory in the generalized gradient approximation plus the on-site Hubbard correction. We present the electronic and magnetic properties, electric and magnetic hyperfine splitting of this impurity in high and low spin states for several charge states at zero pressure, which were then extended to high pressures. For the impurity in the neutral charge state, our results indicated that there is a metastable intermediate spin state (S=1), in addition to the high (S=2) and low (S=0) spin states. Those results were discussed in the context of an intermediate spin state, experimentally identified in ferrosilicate perovskite.

description: Während in vielen Fächern Zeitschriftenartikel den Hauptteil der wissenschaftlichen Publikationen ausmachen, spielen in einigen Fachgebieten Proceedings eine mindestens ebenso wichtige Rolle. Insbesondere in der Informatik und den Ingenieurwissenschaften stehen die Konferenzberichte im Zentrum der wissenschaftlichen Kommunikation. Dennoch erfahren sie bisher vergleichsweise wenig Beachtung im Rahmen der Open-Access-Transformation – und das, obwohl der Imperativ barrierefreier und rascher Verfügbarkeit für diese Publikationen eigentlich im Besonderen gilt. Konferenzen und Proceedings weisen jedoch auch formateigene Charakteristika auf, die häufig wenig zu den etablierten Angeboten und Kriterien passen. Die Konferenzen erfüllen kommunikative (unmittelbarer Austausch), soziale (Networking, Ausdefinition von Forschungsgebieten) und wissenschaftspolitische Funktionen (Agenda ausrichtender Einrichtungen) und stehen im Spannungsfeld verschiedener Interessen. Was davon publiziert wird und wie publiziert wird, differiert stark und reicht von renommierten Proceedings-Journals bis zur freien Veröffentlichung heterogener Materialien auf den Seiten der Konferenzveranstalter. Der Vortrag richtet die Aufmerksamkeit auf Konferenzen und Proceedings als einen bislang wenig beachteten Bereich der wissenschaftlichen Kommunikation und greift dazu Ergebnisse einer Projektvorstudie auf, die 2018 an der TIB durchgeführt wurde. Er beleuchtet die speziellen Bedingungen und Anforderungen, die Konferenzen und Konferenzberichte bieten und präsentiert eine differenzierende Bestandsaufnahme zu den existierenden Open-Access-Optionen für Proceedings. Auf dieser Basis wird diskutiert, welche Herausforderungen und welche Chancen Proceedings für eine erfolgreiche, nachhaltige Open-Access-Transformation bieten.

description: This paper presents results of an all-sky search for periodic gravitational waves in the frequency range [50,1 190] Hz and with frequency derivative range of ∼[−20,1.1]×10−10 Hz s−1 for the fifth LIGO science run (S5). The search uses a noncoherent Hough-transform method to combine the information from coherent searches on time scales of about one day. Because these searches are very computationally intensive, they have been carried out with the Einstein@Home volunteer distributed computing project. Postprocessing identifies eight candidate signals; deeper follow-up studies rule them out. Hence, since no gravitational wave signals have been found, we report upper limits on the intrinsic gravitational wave strain amplitude h0. For example, in the 0.5 Hz-wide band at 152.5 Hz, we can exclude the presence of signals with h0 greater than 7.6×10−25 at a 90% confidence level. This search is about a factor 3 more sensitive than the previous Einstein@Home search of early S5 LIGO data.

description: A new nine-dimensional (9D), \textit{ab initio} electric dipole moment surface (DMS) of methane in its ground electronic state is presented. The DMS is computed using an explicitly correlated coupled cluster CCSD(T)-F12 method in conjunction with an F12-optimized correlation consistent basis set of the TZ-family. A symmetrized molecular bond representation is used to parameterise the 9D DMS in terms of sixth-order polynomials. Vibrational transition moments as well as band intensities for a large number of IR-active vibrational bands of $^{12}$CH$_4$ are computed by vibrationally averaging the \textit{ab initio} dipole moment components. The vibrational wavefunctions required for these averages are computed variationally using the program TROVE and a new `spectroscopic' $^{12}$CH$_4$ potential energy surface. The new DMS will be used to produce a hot line list for $^{12}$CH$_4$.

description: The first observing run of Advanced LIGO spanned 4 months, from 12 September 2015 to 19 January 2016, during which gravitational waves were directly detected from two binary black hole systems, namely GW150914 and GW151226. Confident detection of gravitational waves requires an understanding of instrumental transients and artifacts that can reduce the sensitivity of a search. Studies of the quality of the detector data yield insights into the cause of instrumental artifacts and data quality vetoes specific to a search are produced to mitigate the effects of problematic data. In this paper, the systematic removal of noisy data from analysis time is shown to improve the sensitivity of searches for compact binary coalescences. The output of the PyCBC pipeline, which is a python-based code package used to search for gravitational wave signals from compact binary coalescences, is used as a metric for improvement. GW150914 was a loud enough signal that removing noisy data did not improve its significance. However, the removal of data with excess noise decreased the false alarm rate of GW151226 by more than two orders of magnitude, from 1 in 770 yr to less than 1 in 186 000 yr.
Baryons and Low-Density Baryonic Matter in 1+1 Dimensional Large N_c QCD with Heavy Quarks

description: This paper studies baryons and baryonic matter in the combined large N_c and heavy quark mass limits of QCD in 1+1 dimension. In this non-relativistic limit, baryons are composed of N_c quarks that interact, at leading order in N_c, through a color Coulomb potential. Using variational techniques, very accurate calculations of single baryon masses and interaction energies of low-density baryon crystal are performed. These results are used to cross-check a general numerical approach applicable for arbitrary quark masses and baryon densities recently proposed by Bringoltz, which is based on a lattice in a finite box with periodic boundary conditions. The Bringoltz method differs from a previous approach of Salcedo, et al. in its treatment of a finite box effect - namely gauge configurations that wind around the box. One might expect these effects to be small for large enough boxes, in which the baryon density approaches zero to high accuracy at the edges. However, the effects of these windings appear to be quite large even in such boxes. The large mass infinite volume calculations performed here are consistent with the results of numerical calculations using the Bringoltz method. The calculation of the baryon crystal interaction energy requires the assumption that at low-densities the ground state is composed of individual baryons, each in a color-singlet state and orthogonal to each other. This assumption is plausible but ad hoc in that one can construct configurations in which the entire state is color-singlet but cannot be broken into individual color-singlet baryons. The interaction energy of low-density baryon crystals calculated with the assumption is consistent with numerical results based on Bringoltz's approach suggesting that the assumption is justified. This further supports a similar assumption that was made in 3+1 dimensions, where no alternative means of calculation exist.
