description: We report transient optical signatures of the orbital-selective Mottness in superconducting KxFe2-ySe2 crystals by using dual-color pump-probe spectroscopy. Besides multi-exponential decay recovery dynamics of photo-induced quasiparticles, a damped oscillatory component due to coherent acoustic phonons emerges when the superconducting phase is suppressed by increasing the temperature or excitation power. The oscillatory component diminishes with significant enhancement of a slow decay component upon raising temperature to 150-160 K. These results are in consistence with the picture of orbital-selective Mott phase transition, indicating a vital role played by electron correlation in the iron-based superconductors.

Single-Star HII Regions as a Probe of Massive Star Spectral Energy Distributions

description: The shape of the OB-star spectral energy distribution is a critical component in many diagnostics of the ISM and galaxy properties. We use single-star HII regions from the LMC to quantitatively examine the ionizing SEDs from widely available CoStar, TLUSTY, and WM-basic atmosphere grids. We evaluate the stellar atmosphere models by matching the emission-line spectra that they predict from CLOUDY photoionization simulations with those observed from the nebulae. The atmosphere models are able to reproduce the observed optical nebular line ratios, except at the highest energy transitions > 40 eV, assuming that the gas distribution is non-uniform. Overall we find that simulations using WM-basic produce the best agreement with the observed line ratios. The rate of ionizing photons produced by the model SEDs is consistent with the rate derived from the \Halpha\ luminosity for standard, log(g) = 4.0 models adopted from the atmosphere grids. However, there is a systematic offset between the rate of ionizing photons from different atmosphere models that is correlated with the relative hardness of the SEDs. In general WM-basic and TLUSTY atmosphere models predict similar effective temperatures, while CoStar predicts effective temperatures that are cooler by a few thousand degrees. We compare our effective temperatures, which depend on the nebular ionization balance, to conventional photospheric-based calibrations from the literature. We suggest that in the future, spectral type to effective temperature calibrations can be constructed from nebular data.

description: We demonstrate the electrical injection and detection of spin-polarized electrons in the Co2FeSi/GaAs hybrid system using lateral transport structures. Spin valve signatures and characteristic Hanle curves are observed both in the nonlocal and the local configuration. The comparatively large magnitude of the local spin valve signal and the high signal-to-noise ratio are attributed to the large spin polarization at the Fermi energy of Co2FeSi in the well-ordered L21 phase.

Quantitative Study of Different Forms of Geometrical Scaling in Deep Inelastic Scattering at HERA

description: We use recently proposed method of ratios to assess the quality of geometrical scaling in deep inelastic scattering for different forms of the saturation scale. We consider original form of geometrical scaling (motivated by the Balitski-Kovchegov (BK) equation with fixed coupling) studied in more detail in our previous paper, and four new hypotheses: phenomenologically motivated case with $Q^2$ dependent exponent $λ$ that governs small $x$ dependence of the saturation scale, two versions of scaling (running coupling 1 and 2) that follow from the BK equation with running coupling, and diffusive scaling suggested by the QCD evolution equation beyond mean field approximation. It turns out that more sophisticated scenarios: running coupling scaling and diffusive scaling are disfavored by the combined HERA data on $e^+p$ deep inelastic structure function $F_2$.

Critical properties of a spin-1 triangular lattice Ising antiferromagnet

description: We employ Monte Carlo simulations in order to investigate critical behavior of a geometrically frustrated spin-1 Ising antiferromagnet on a triangular lattice in the presence of a single-ion anisotropy. It has been previously found that long-range order can exist in the isotropic system with a spin larger than some critical value estimated as 11/2. We show that the presence of the single-ion anisotropy can lead to a partial long-range order in the low-temperature region even below this critical value, namely for the spin 1, within a certain range of the anisotropy strength. At higher temperatures we identify another phase of the Berezinsky-Kosterlitz-Thouless type and using a finite-size scaling analysis evaluate the correlation decay exponent. We also study densities of various local spin patterns in the respective phases.

Making use of a collinearly-improved BFKL equation at next-to-leading order and a treatment of the running of the coupling using non-Abelian physical renormalization together with the BLM scale choice allows us to reach low values of Q^2. We also provide some predictions for future lepton-hadron colliders.

description: We investigate using first-principles calculations the atomic structure of the orthorhombic phase of Ta$_2$O$_5$. Although this structure has been studied for decades, the correct structural model is controversial owing to the complication of structural disorder. We identify a new low-energy high-symmetry structural model where all Ta and O atoms have correct formal oxidation states of +5 and -2, respectively, and the experimentally reported triangular lattice symmetry of the Ta sublattice appears dynamically at finite temperatures. To understand the complex atomic structure of the Ta$_2$O$_3$ plane, a triangular graph-paper representation is devised and used alongside oxidation state analysis to reveal infinite variations of the low-energy structural model. The structural disorder of Ta$_2$O$_5$ observed in experiments is attributed to the intrinsic structural variations, and oxygen vacancies that drive collective relaxation of the O sublattice.

description: The resonant magnetic reflectivity of Co/Mg multilayers around the Co L2,3 absorption edge is simulated then measured on a specifically designed sample. The dichroic signal is obtained when making the difference between the two reflectivities measured with the magnetic field applied in two opposite directions parallel to the sample surface. The simulations show that the existence of magnetic dead layers at the interfaces between the Co and Mg layers leads to an important increase of the dichroic signal measured in the vicinity of the third Bragg peak that otherwise should be negligible. The measurements are in agreement with the model introducing 0.25 nm thick dead layers. This is attributed to the Co atoms in contact with the Mg layers and thus we conclude that the Co-Mg interfaces are abrupt from the magnetic point of view.

Superorbital Phase-Resolved Analysis of SMC X-1

description: The high-mass X-ray binary SMC X-1 is an eclipsing binary with an orbital period of 3.89 d. This system exhibits a superorbital modulation with a period varying between ~40 d and ~65 d. The instantaneous frequency and the corresponding phase of the superorbital modulation can be obtained by a recently developed time-frequency analysis technique, the Hilbert-Huang transform (HHT). We present a phase-resolved analysis of both the spectra and the orbital profiles with the superorbital phase derived from the HHT. The X-ray spectra observed by the Proportional Counter Array onboard the Rossi X-ray Timing Explorer are fitted well by a blackbody plus a Comptonized component. The plasma optical depth, which is a good indicator of the distribution of material along the line of sight, is significantly anti-correlated with the flux detected at 2.5-25 keV. However, the relationship between the plasma optical depth and the equivalent width of the iron line is not monotonic: there is no significant correlation for fluxes higher than ~35 mCrab but clear positive correlation when the intensity is lower than ~20 mCrab. This indicates that the iron line production is dominated by different regions of this binary system in different superorbital phases. To study the dependence of the orbital profile on the superorbital phase, we obtained the eclipse profiles by folding the All Sky Monitor light curve with the orbital period for different superorbital states. A dip feature, similar to the pre-eclipse dip in Her X-1, lying at orbital phase ~0.6-0.85, was discovered during the superorbital transition state. This indicates that the accretion disk has a bulge that absorbs considerable X-ray emission in the stream-disk interaction region. The dip width is anti-correlated with the flux, and this relation can be interpreted by the precessing tilted accretion disk scenario.

description: We have studied 14 southern infrared dark clouds (IRDCs) using the data taken from the Millimetre Astronomy Legacy Team 90 GHz (MALT90) survey and the GLIMPSE and MIPSGAL mid-infrared survey of the inner Galaxy. The physical and chemical characteristics of the 14 IRDCs are investigated using N2H+(1-0), HNC(1-0), HCO+(1-0), and HCN(1-0) molecular lines. We find that the 14 IRDCs are in different evolutionary stages from the "starless" to the sources with an UCHII region. Three IRDCs are detected to have the star forming activities. The integrated intensity ratios I(HCO+)/I(HCN), I(N2H+)/I(HCN), and I(HNC)/I(HCN) are all about 1.5, which is different from the previous measurements, suggesting that the integrated intensity ratios may be affected by the cloud environments. The integrated intensities of HNC, HCO+ and HCN show a tight correlation for the 14 IRDCs, implying a close link to the chemical evolution of these three species in the IRDCs. The derived excitation temperature for each IRDC is less than 25 K. We estimate the abundances of the four molecules from 10^(-11) to 10^(-9), and the average abundance ratios N(HNC)/N(HCN) = 1.4+ -0.50, N(HNC)/N(HCO+) = 1.74 + - 0.22, N(HCN)/N(HCO+)= 1.21 + - 0.41.

We also study the isometric automorphism group of these algebras and prove that it decomposes into the semidirect product of an abelian group by a torsion free group.

description: This presentation was delivered as part of the webinar, "Librarians Reimagining Open Access: Beyond Paywalls", on 20 March 2025. 

Speaker: Joanne Fitzpatrick, Accessibility and Engagement Manager on the Open Book Futures project. 

Abstract: The Open Access movement has always focused on the important work of removing paywall barriers to accessing publicly funded academic work, and while this work is still ongoing, are there other barriers to access that we could tackle alongside this? Speaking as a researcher on the Open Book Futures project specifically working on Work Package 5 - accessibility, this session will ask whether other barriers to access, such as accessibility issues, power imbalances and censorship, should be considered part of open access?

The format of the session will be a 'live survey' where a range of ideas, resources and concepts will be presented that will provide inspiration for you to share your thoughts on this Google Form. You can attend live and fill in the form during the session or afterwards, or watch the recording later and complete the Google form by the end of April. There will be a stronger focus on accessibility barriers, in line with the focus of the work package. The event will be fully online, on Teams, with joining details sent beforehand.

description: Many schemes for implementing quantum information processing require that the atomic states used have a non-zero magnetic moment, however such magnetically sensitive states of an atom are vulnerable to decoherence due to fluctuating magnetic fields. Dressing an atom with an external field is a powerful method of reducing such decoherence [N. Timoney et al., Nature 476, 185], even if the states being dressed are strongly coupled to the environment. We introduce an experimentally simpler method of manipulating such a dressed-state qubit, which allows the implementation of general rotations of the qubit, and demonstrate this method using a trapped ytterbium ion.

description: The model-theoretic Grothendieck ring of a first order structure, as defined by Krajicěk and Scanlon, captures some combinatorial properties of the definable subsets of finite powers of the structure. In this paper we compute the Grothendieck ring, $K_0(M_\mathcal R)$, of a right $R$-module $M$, where $\mathcal R$ is any unital ring. As a corollary we prove a conjecture of Prest that $K_0(M)$ is non-trivial, whenever $M$ is non-zero. The main proof uses various techniques from the homology theory of simplicial complexes.

description: Aufgrund von zunehmend schlankeren Bauwerken nimmt der dynamische Beanspruchungsanteil gegenüber dem Anteil der ständigen Beanspruchungen bei Brückenbauwerken und Windenergieanlagen zu. Daraus ergibt sich ein großer Forschungsbedarf im Bereich der Betonermüdung. Im Rahmen dieser Arbeit werden kraftgeregelte Druckschwellversuche energetisch ausgewertet. Aus den Spannungs-Dehnungslinien lassen sich dabei neben einem elastischen und plastischen Energieanteil ebenfalls die Dissipationsenergiewerte bestimmen. Diese Dissipationsenergie ist wiederum für die Erwärmung der Probekörper infolge der zyklisch-mechanischen Beanspruchung verantwortlich. Auf Basis der festgestellten Korrelation zwischen der Probekörpererwärmung und der Schädigungsentwicklung werden die Hypothesen, die einen Zusammenhang zwischen der Dissipationsenergie und der Rissanzahl sowie der Rissgröße im Probekörper beschreiben, untersucht. Es zeigt sich, dass sich die Verläufe der mit jedem Lastwechsel dissipierten Energie analog zu den bereits bekannten Verläufen anderer Messparameter und Schädigungsindikatoren in drei Phasen aufteilen lassen. Ein direkter quantitativer Zusammenhang zwischen dem Schädigungsgrad und der Dissipationsenergie je Lastwechsel ist hingegen nicht erkennbar. Aus der Auswertung der bis zum Versagen eines Probekörpers kumulierten Dissipationsenergie resultiert hingegen ein funktionaler Zusammenhang zur jeweiligen Bruchlastwechselzahl. Sämtliche Auswertungspunkte, die durch die Bruchlastwechselzahlen und den bis zum jeweiligen Versagen kumulierten Dissipationsenergiewerten beschrieben werden, liegen auf einer Kurve. Diese lässt sich durch eine Potenzfunktion beschreiben und wird als Versagenskurve bezeichnet. Die Gültigkeit der Versagenskurven wird durch die Auswertung weiterer Versuchsserien validiert. Dabei ergeben sich aus der Form der Versagenskurve Rückschlüsse auf das Ermüdungsverhalten der Versuchsserie. Aufbauend auf den Versagenskurven wird in dieser Arbeit ein neuer Schädigungsparameter eingeführt und ein neues Schädigungsmodell beschrieben. Der Schädigungsparameter ergibt sich aus dem relativen Abstand zwischen der kumulierten Dissipationsenergie des Probekörpers und der Versagenskurve der Versuchsserie. Sobald die Werte übereinstimmen, tritt das Versagen des Probekörpers ein. Aus den Auswertungen ergeben sich plausible dreiphasige Verläufe des Schädigungsparameters über die Versuchslaufzeit. Durch Modellerweiterungen kann das Modell sowohl für Einstufenversuche mit festgelegten Spannungsniveaus als auch für mehrstufige Versuche mit abnehmenden oder ansteigenden Oberspannungsniveaus verwendet werden.

description: We investigate the effect of anti-ferromagnetic (AF) quantum criticality on the magnetic penetration depth $λ(T)$ in line-nodal superconductors, including the cuprates, the iron pnictides, and the heavy-fermion superconductors. The critical magnetic fluctuation renormalizes the current vertex and drastically enhances zero-temperature penetration depth $λ(0)$, which is more remarkable in the iron-pnictide case due to the Fermi-surface topology. Additional temperature ($T$) dependence of the current renormalization makes the expected $T$-linear behavior at low temperatures approaching to $T^{1.5}$ asymptotically. These anomalous behaviors are well consistent with experimental observations. We stress that $λ(T)$ is a good probe to detect the AF quantum critical point in the superconducting state.

title: A Case Study in the Development of a Cost Reduction Methodology in the Public Sector
Creators: name: Haines, Ross Cooper
Publisher: name: Old Dominion University Libraries
Year: 1990

description: Intense fiscal pressures have caused the Department of Defense (DoD) to explore new ways of reducing operating expenses. The primary technique used to achieve this objective is the use of competition - recently for maintenance requirements not previously subjected to competition. One such maintenance requirement is the periodic overhaul of one of the Navy's front line fighter aircraft - the F-14A Tomcat. This case study documents the cost reduction methodology developed by the DoD's incumbent overhaul facility in preparation for competition. The methodology discusses task time estimation, cost center structure, labor rate development and analysis, internal cost transfers as well as the development, use and institutionalization of appropriate financial Decision Support Systems. The study is presented such that it can be used as a step-by-step guide in analyzing the cost efficiency of virtually any business. Furthermore it is written to a level of detail, and in a vernacular which makes it useful for those with little or no financial background.

description: The development of concurrent applications is challenging because of the complexity of concurrent designs and the hazards of concurrent programming. Architectural modeling using the Unified Modeling Language (UML) can support the development process, but the problem of mapping the model to a concurrent implementation remains. This paper addresses this problem by defining a scheme to map concurrent UML designs to a concurrent object-oriented program. Using the COMET method for the architectural design of concurrent object-oriented systems, each component and connector is annotated with a stereotype indicating its behavioral design pattern. For each of these patterns, a reference implementation is provided using SCOOP, a concurrent object-oriented programming model. We evaluate this development process using a case study of an ATM system, obtaining a fully functional implementation based on the systematic mapping of the individual patterns. Given the strong execution guarantees of the SCOOP model, which is free of data races by construction, this development method eliminates a source of intricate concurrent programming errors.
Spontaneous Mirror Symmetry Breaking in the Limited Enantioselective Autocatalysis Model: Abyssal Hydrothermal Vents as Scenario for the Emergence of Chirality in Prebiotic Chemistry

description: The emergence of chirality in enantioselective autocatalysis for compounds unable to transform according to the Frank-like reaction network is discussed with respect to the controversial limited enantioselectivity (LES) model composed of coupled enantioselective and non-enantioselective autocatalyses. The LES model cannot lead to spontaneous mirror symmetry breaking (SMSB) either in closed systems with a homogeneous temperature distribution nor in closed systems with a stationary non-uniform temperature distribution. However, simulations of chemical kinetics in a two-compartment model demonstrate that SMSB may occur if both autocatalytic reactions are spatially separated at different temperatures in different compartments but coupled under the action of a continous internal flow. In such conditions the system can evolve, for certain reaction and system parameters, towards a chiral stationary state, i.e., the system is able to reach a bifurcation point leading to SMSB. Numerical simulations using reasonable chemical parameters suggest that an adequate scenario for such a SMSB would be that of abyssal hydrothermal vents, by virtue of the typical temperature gradients found there and the role of inorganic solids mediating chemical reactions in an enzyme-like role.

title: Development of a Knowledge Based System for Wastewater Pipeline Failure Risk Assessment
Creators: name: Ngaliga, Adam Mayanzani
Publisher: name: Old Dominion University Libraries
Year: 1993

description: The purpose of this thesis was to study and analyze the wastewater pipeline failure risk assessment process, and then design and develop an effective and efficient wastewater pipeline risk assessment tool for the Hampton Roads Sanitation District, in Virginia, U.S.A. A knowledge based system was developed using an expert system building shell (Xi-Plus).

The system design is based on the knowledge elicited from the experts and literature in sanitary pipeline failure risk evaluation. The knowledge base contains both heuristics and procedural rules. The system interprets the information provided by the user and reasons from that information to reach conclusions on wastewater pipeline section failure risk. Based on risk, the section is ranked relative to other pipeline sections. By using the system, HRSD decisions on pipeline segments replacements and rehabilitation alternatives can be made based on the rankings.

description: Programming languages are essential tools for developers, and their evolution plays a crucial role in supporting the activities of developers. One instance of programming language evolution is the introduction of syntactic sugars, which are additional syntax elements that provide alternative, more readable code constructs. However, the process of designing and evolving a programming language has traditionally been guided by anecdotal experiences and intuition. Recent advances in tools and methodologies for mining open-source repositories have enabled developers to make data-driven software engineering decisions. In light of this, this paper proposes an approach for motivating data-driven programming evolution by applying frequent subgraph mining techniques to a large dataset of 166,827,154 open-source Java methods. The dataset is mined by generalizing Java control-flow graphs to capture broad programming language usages and instances of duplication. Frequent subgraphs are then extracted to identify potentially impactful opportunities for new syntactic sugars. Our diverse results demonstrate the benefits of the proposed technique by identifying new syntactic sugars involving a variety of programming constructs that could be implemented in Java, thus simplifying frequent code idioms. This approach can potentially provide valuable insights for Java language designers, and serve as a proof-of-concept for data-driven programming language design and evolution.
