description: The principal objective of this paper is to summarize current pavement management activities in Kentucky. Early pavement management activities generally were decentralized (involving a number of transportation functions such as planning, design, construction, maintenance, and research) and involved long-term monitoring for skid resistance and ride quality (roughness).  Current pavement management activities may be categorized by evaluation, project selection, and development of recommendations for pavement rehabilitation strategies. Pavement evaluation activities at the statewide system level typically involve assessments of ride quality (ridesbility index) and estimated pavement serviceability, skid resistance, visual condition ratings, and the accumulation of traffic volumes and pavement fatigue. Funding allocations to highway districts involves the application of limiting criteria to system level data obtained during the evaluation phase. Factors considered include rideability index (estimated from roughness measurements), skid resistance, visual condition ratings, accumulation of traffic volumes and fatigue, and engineering judgment. Recommendations for rehabilitation strategies also may be based on structural evaluations using deflection measurements.  Typical rehabilitation strategies are discussed. Procedures and criteria for the allocation and distribution of funding to the highway districts are presented.

description: This article explores new physically viable wormhole solutions within the framework of f(R,Lm) gravity theory, incorporating noncommutative backgrounds and conformal symmetries. The study investigates the impact of model parameters on the existence and properties of wormholes. The derived shape function is found to obey all the required criteria. Specific attention is given to traceless wormholes with Gaussian and Lorentzian distributions, investigating the behavior of the shape functions and energy conditions. In both cases, the presence of exotic fluid is confirmed.

Starting the Bandwagon: A Historiography of African American Mothers' Leadership during Voluntary School Desegregation, 1954-1971
Creators: name: Wilson, Camille M.
Publisher: name: Advancing Women in Leadership Journal
Year: 2017

description: In this article, the author presents a historiography that considers the leadership that African American women, particularly mothers, played in U.S. school desegregation. Discussion moves beyond offering a political analysis of school integration politics that is male centered, bounded by a legalistic frame, or steeped within general discussions of the political clashes between integrationists and segregationists to recast significant historical events through a more nuanced womanist lens. Literature is reviewed and archival data from 1954 to 1971 are marshaled to shed light on why and how African American mothers contributed to the school desegregation movement, particularly in Greensboro, NC. The author suggests what lessons can be gleaned from the mothers' legacy to extend conceptualizations of transformative educational leadership.

description: The JPEG algorithm compresses a digital image by filtering its high spatial-frequency components. Similarly, we introduce a quantum algorithm that uses the quantum Fourier transform to discard the high spatial-frequency qubits of an image, downsampling it to a lower resolution. This allows one to capture, compress, and send images even with limited quantum resources for storage and communication. We show under which conditions this protocol is advantageous with respect to its classical counterpart.

description: We consider the familiar junction conditions described by Israel for thin timelike walls in Einstein-Hilbert gravity. One such condition requires the induced metric to be continuous across the wall. Now, there are many spacetimes with sources confined to a thin wall for which this condition is violated and the Israel formalism does not apply. However, we explore the conjecture that the induced metric is in fact continuous for any thin wall which models spacetimes containing only positive energy matter. Thus, the usual junction conditions would hold for all positive energy spacetimes. This conjecture is proven in various special cases, including the case of static spacetimes with spherical or planar symmetry as well as settings without symmetry which may be sufficiently well approximated by smooth spacetimes with well-behaved null geodesic congruences.

description: Large-scale sky surveys require companion large volume simulated mock catalogs. To ensure precision cosmology studies are unbiased, the correlations in these mocks between galaxy properties and their large-scale environments must be realistic. Since galaxies are embedded in dark matter halos, an important first step is to include such correlations -- sometimes called assembly bias -- for dark matter halos. However, galaxy properties correlate with smaller scale physics in halos which large simulations struggle to resolve. We describe an algorithm which addresses and largely mitigates this problem. Our algorithm exploits the fact that halo assembly bias is unchanged as long as correlations between halo property $c$ and the intermediate-scale tidal environment $α$ are preserved. Therefore, knowledge of $α$ is sufficient to assign small-scale, otherwise unresolved properties to a halo in a way which preserves its large-scale assembly bias accurately. We demonstrate this explicitly for halo internal properties like formation history (concentration $c_{\rm 200b}$), shape $c/a$, dynamics $c_{v}/a_{v}$, velocity anisotropy $β$ and angular momentum (spin $λ$). Our algorithm increases a simulation's reach in halo mass and number density by an order of magnitude, with improvements in the bias signal as large as 45% for 30-particle halos, thus significantly reducing the cost of mocks for future weak lensing and redshift space distortion studies.

Tuning Rules for a Class of Passivity-Based Controllers for Mechanical Systems

description: In this paper, we propose several rules to tune the gains for a class of passivity-based controllers for nonlinear mechanical systems. Such tuning rules prescribe a desired local transient response behavior to the closed-loop system. To establish the tuning rules, we implement a PID passivity-based controller. Then, we linearize the closed-loop system, and we transform the matrix of the resulting system into a class of saddle point matrices to analyze the influence of the control gains, in terms of the oscillations and the rise time, on the transient response of the closed-loop system. Hence, the resulting controllers stabilize the plant and simultaneously address the performance of the closed-loop system. Moreover, our analysis provides a clear insight into how the kinetic energy, the potential energy, and the damping of the mechanical system are related to its transient response, endowing in this way the tuning rules with a physical interpretation. Additionally, we corroborate the analytical results through the practical implementation of a controller that stabilizes a two degrees-of-freedom (DoF) planar manipulator, where the control gains are tuned following the proposed rules.

Building Entanglement Entropy out of Correlation Functions for Interacting Fermions

description: We provide a prescription to construct Rényi and von Neumann entropy of a system of interacting fermions from a knowledge of its correlation functions. We show that Rényi entanglement entropy of interacting fermions in arbitrary dimensions can be represented by a Schwinger Keldysh free energy on replicated manifolds with a current between the replicas. The current is local in real space and is present only in the subsystem which is not integrated out. This allows us to construct a diagrammatic representation of entanglement entropy in terms of connected correlators in the standard field theory with no replicas. This construction is agnostic to how the correlators are calculated, and one can use calculated, simulated or measured values of the correlators in this formula. Using this diagrammatic representation, one can decompose entanglement into contributions which depend on the one-particle correlator, two particle correlator and so on. We provide analytic formula for the one-particle contribution and a diagrammatic construction for higher order contributions. We show how this construction can be extended for von-Neumann entropy through analytic continuation. For a practical implementation of a quantum state, where one usually has information only about few-particle correlators, this provides an approximate way of calculating entanglement commensurate with the limited knowledge about the underlying quantum state.

Perceptions of School Leaders: Exploring School Climate Data Based on Principal Gender and Student Achievement
Creators: name: Nichols, Joe
Publisher: name: Advancing Women in Leadership Journal
Year: 2017

description: This project explored the climate data of 33 elementary schools in an urban school system to determine the relationship among perceptions of effective school leadership and student achievement. Data was compiled from teachers (n = 847) at each elementary school in regard to their perceptions of effective leadership of their school principal. Data was compared to student achievement and disaggregated based upon the gender of the principal. In summary, female principals were rated significantly lower on their leadership skills than male principals by their staff. In contrast, when student standardized test data were explored and cross-referenced with the gender of the principal, student achievement at schools with female leadership was comparable with that of elementary sites with male leadership.

description: In this work we characterise the C*-algebras A generated by projections with the property that every pair of projections in A has positive angle, as certain extensions of abelian algebras by algebras of compact operators. We show that this property is equivalent to a lattice theoretic property of projections and also to the property that the set of finite-dimensional *-subalgebras of A is directed.

description: The knowledge of the dynamical state of galaxy clusters allows to alleviate systematics when observational data from these objects are applied in cosmological studies. Evidence of correlation between the state and the morphology of the clusters is well studied. The morphology can be inferred by images of the surface brightness in the X-ray band and of the thermal component of the Sunyaev-Zel'dovich (tSZ) effect in the millimetre range. For this purpose, we apply, for the first time, the Zernike polynomial decomposition, a common analytic approach mostly used in adaptive optics to recover aberrated radiation wavefronts at the telescopes pupil plane. With this novel way we expect to correctly infer the morphology of clusters and so possibly, their dynamical state. To verify the reliability of this new approach we use more than 300 synthetic clusters selected in THE THREE HUNDRED project at different redshifts ranging from 0 up to 1.03. Mock maps of the tSZ, quantified with the Compton parameter, $y$-maps, are modelled with Zernike polynomials inside $R_{500}$, the cluster reference radius. We verify that it is possible to discriminate the morphology of each cluster by estimating the contribution of the different polynomials to the fit of the map. The results of this new method are correlated with those of a previous analysis made on the same catalogue, using two parameters that combine either morphological or dynamical-state probes. We underline that instrumental angular resolution of the maps has an impact mainly when we extend this approach to high-redshift clusters.

description: We develop further the approach to upper and lower bounds in quantum dynamics via complex analysis methods which was introduced by us in a sequence of earlier papers. Here we derive upper bounds for non-time averaged outside probabilities and moments of the position operator from lower bounds for transfer matrices at complex energies. Moreover, for the time-averaged transport exponents, we present improved lower bounds in the special case of the Fibonacci Hamiltonian. These bounds lead to an optimal description of the time-averaged spreading rate of the fast part of the wavepacket in the large coupling limit. This provides the first example which demonstrates that the time-averaged spreading rates may exceed the upper box-counting dimension of the spectrum.

description: Achieving chemical accuracy with shallow quantum circuits is a significant challenge in quantum computational chemistry, particularly for near-term quantum devices. In this work, we present a Clifford-based Hamiltonian engineering algorithm, namely CHEM, that addresses the trade-off between circuit depth and accuracy. Based on variational quantum eigensolver and hardware-efficient ansatz, our method designs Clifford-based Hamiltonian transformation that (1) ensures a set of initial circuit parameters corresponding to the Hartree--Fock energy can be generated, (2) effectively maximizes the initial energy gradient with respect to circuit parameters, (3) imposes negligible overhead for classical processing and does not require additional quantum resources, and (4) is compatible with any circuit topology. We demonstrate the efficacy of our approach using a quantum hardware emulator, achieving chemical accuracy for systems as large as 12 qubits with fewer than 30 two-qubit gates. Our Clifford-based Hamiltonian engineering approach offers a promising avenue for practical quantum computational chemistry on near-term quantum devices.

Making Meaning of Barriers and Adversity: Experiences of Women Leaders in Higher Education
Creators: name: Diehl, Amy B.
Publisher: name: Advancing Women in Leadership Journal
Year: 2017

description: Extensive research has demonstrated that women aspiring to and serving as leaders face many barriers, which creates a glass ceiling effect for women's advancement into top leadership positions. In higher education, women hold only 26 percent of all college and university presidencies. The objective of this qualitative study was to discover the meaning of adversity for women leaders in higher education. Face-to-face interviews were conducted with 26 women in senior leadership roles in higher education. The research question was "How do women leaders in higher education make meaning of adversity?" Participants reported experiencing wide-ranging types of adversity, including gender-based leadership barriers. While adversity had a generally positive effect on participant identity, it had disparate effects on self-esteem, power, connections to others, and worldviews. The common thread was that adversity can lead to growth and opportunity but such benefits are intertwined with pain and loss.

description: We solve for the evolution of the vertical extent of the convective region of a neutron star atmosphere during a Type I X-ray burst. The convective region is well-mixed with ashes of nuclear burning and its extent determines the rise time of the burst light curve. Using a full nuclear reaction network, we show that the maximum vertical extent of the convective region during photospheric radius expansion (RE) bursts can be sufficiently great that: (1) some ashes of burning are ejected by the radiation driven wind during the RE phase and, (2) some ashes of burning are exposed at the neutron star surface following the RE phase. We find that ashes with mass number A ~ 30 - 60 are mixed in with the ejected material. We calculate the expected column density of ejected and surface ashes in hydrogen-like states and determine the equivalent widths of the resulting photoionization edges from both the wind and neutron star surface. We find that these can exceed 100 eV and are potentially detectable. A detection would probe the nuclear burning processes and might enable a measurement of the neutron star gravitational redshift. In addition, we find that in bursts with pure helium burning layers, protons from (alpha, p) reactions cause a rapid onset of the 12C(p, gamma)13N(alpha, p)16O reaction sequence. The sequence bypasses the relatively slow 12C(alpha, gamma)16O reaction and leads to a sudden surge in energy production that is directly observable as a rapid (~ ms) increase in flux during burst rise.

description: As we walk towards our destinations, our trajectories are constantly influenced by the presence of obstacles and infrastructural elements: even in absence of crowding our paths are often curved. Over the last two decades pedestrian dynamics have been extensively studied aiming at quantitative models with both fundamental and technological relevance. Walking kinematics along straight paths have been experimentally investigated and quantitatively modeled in the diluted limit (i.e. in absence of pedestrian-pedestrian interactions). It is natural to expect that models for straight paths may be an accurate approximations of the dynamics even for paths with curvature radii much larger than the size of a single person. Conversely, as paths curvature increase one may expect larger and larger deviations. As no clear experimental consensus has been reached yet in the literature, here we accurately and systematically investigate the effect of paths curvature on diluted pedestrian dynamics. Thanks to a extensive and highly accurate set of real-life measurements campaign, we derive and validate via a Langevin-like social-force model capable of quantitatively describing both averages and fluctuations. Leveraging on the differential geometric notion of covariant derivative, we generalize previous work by some of the authors, effectively casting a Langevin social-force model for the straight walking dynamics in a curved geometric setting. We deem this the necessary first step to understand and model the more general and ubiquitous case of pedestrians following curved paths in the presence of crowd traffic.

description: The aim of this study was to examine the relationship between internal locus of control and job satisfaction, job stress and sexes of female head-teachers of primary schools in Makassar, Indonesia. A total of 85 female respondents returned the completed questionnaires. This is a one - phased quantitative research using questionnaire instruments to collect data. The questionnaires were distributed by mailing them to the schools' address of each respondent. The data were analyzed using SPSS package. Arithmetic statistics used such as mean, standard deviation, Pearson's product moment correlation and stepwise multiple regression analysis. To establish content validity which supported construct validity, a principal component factor analysis was applied. The results of this study revealed that there was a significant correlation between internal locus of control and job satisfaction and job stress of female headteachers at elementary schools in Makassar. There was no relationship between sexes (married with children and had maid; married with children had no maid ) with internal locus of control of female headteachers in primary schools in Makassar, Indonesia.

description: It is widely known that giant planets have the capacity to open deep gaps in their natal gaseous protoplanetary discs. It is unclear, however, how gas accretion onto growing planets influences the shape and depth of their growing gaps. We performed isothermal hydrodynamical simulations with the Fargo-2D1D code, which assumes planets accreting gas within full discs that range from 0.1 to 260 AU. The gas accretion routine uses a sink cell approach, in which different accretion rates are used to cope with the broad range of gas accretion rates cited in the literature. We find that the planetary gas accretion rate increases for larger disc aspect ratios and greater viscosities. Our main results show that gas accretion has an important impact on the gap-opening mass: we find that when the disc responds slowly to a change in planetary mass (i.e., at low viscosity), the gap-opening mass scales with the planetary accretion rate, with a higher gas accretion rate resulting in a larger gap-opening mass. On the other hand, if the disc response time is short (i.e., at high viscosity), then gas accretion helps the planet carve a deep gap. As a consequence, higher planetary gas accretion rates result in smaller gap-opening masses. Our results have important implications for the derivation of planet masses from disc observations: depending on the planetary gas accretion rate, the derived masses from ALMA observations might be off by up to a factor of two. We discuss the consequences of the change in the gap-opening mass on the evolution of planetary systems based on the example of the grand tack scenario. Planetary gas accretion also impacts stellar gas accretion, where the influence is minimal due to the presence of a gas-accreting planet.

Increasing the Proportion of Female Superintendents in the 21st Century
Creators: name: Wallace, Teresa
Publisher: name: Advancing Women in Leadership Journal
Year: 2017

description: With the proportion of females in the superintendency being 23% in 2012, and increasing by only 0.7% annually, it will take nearly 80 years for females to be proportionately represented in public schools. This study sample consisted of 63 female superintendents, representing 51% of the overall population of female superintendents in the 6 southeastern states where the study took place. The 6 states were chosen because each has approximately the national average of female superintendents. Female superintendents in the six southeastern states were asked what advice they would give to aspiring female superintendents and to recommend strategies for increasing the proportion of females in the superintendency. Participants offered valuable advice to aspiring female superintendents on how to navigate the system and be successful. They recommended practical strategies for attracting female candidates and increasing the proportion of females in the superintendency.

description: This paper is motivated by a general question: for which values of k and n is the universal Burnside kei of k generators and Kei "exponent" n, $\bar Q(k,n)$, finite? It is known (starting from the work of M. Takasaki (1942)) that $\bar Q(2,n)$ is isomorphic to the dihedral quandle Z_n and $\bar Q(3,3)$ is isomorphic to Z_3 + Z_3. In this paper we give descriptions of $\bar Q(4,3)$ and $\bar Q(3,4)$. We also investigate some properties of arbitrary quandles satisfying the universal Burnside relation (of "exponent" n) a=...a*b*...*a*b. In particular, we prove that the order of a finite commutative kei is a power of 3. Invariants of links related to Burnside kei $\bar Q(k,n)$ are invariant under n-moves.

description: Quantum tunneling is the phenomenon that makes superconducting circuits "quantum". Recently, there has been a renewed interest in using quantum tunneling in phase space of a Kerr parametric oscillator as a resource for quantum information processing. Here, we report a direct observation of quantum interference induced by such tunneling in a planar superconducting circuit through Wigner tomography. We experimentally elucidate all essential properties of this quantum interference, such as mapping from Fock states to cat states, a temporal oscillation due to the pump detuning, as well as its characteristic Rabi oscillations and Ramsey fringes. Finally, we perform gate operations as manipulations of the observed quantum interference. Our findings lay the groundwork for further studies on quantum properties of superconducting Kerr parametric oscillators and their use in quantum information technologies.

description: The capture and inspiral of compact stellar masses into massive black holes is an important source of low-frequency gravitational waves (with frequencies of ~1-100mHz), such as those that might be detected by the planned Laser Interferometer Space Antenna (LISA). Simulations of stellar clusters designed to study this problem typically rely on simple treatments of the black hole encounter which neglect some important features of orbits around black holes, such as the minimum radii of stable, non-plunging orbits. Incorporating an accurate representation of the orbital dynamics near a black hole has been avoided due to the large computational overhead. This paper provides new, more accurate, expressions for the energy and angular momentum lost by a compact object during a parabolic encounter with a non-spinning black hole, and the subsequent inspiral lifetime. These results improve on the Keplerian expressions which are now commonly used and will allow efficient computational simulations to be performed that account for the relativistic nature of the spacetime around the central black hole in the system.

description: The Diels-Alder reaction was discovered in 1928 and is still the pre-eminent method for the synthesis of six-membered carbocyclic and heterocyclic rings. This thesis comprises four chapters of results and discussion with the Diels-Alder reaction as a theme. Chapter 2 describes a reinvestigation of a long forgotten double Diels-Alder reaction. Chapters 3 and 4 explore the chemistry of conjugated furans and oligofurans. Chapter 5 explores the Diels-Alder endo/exo selectivity of the archetypal diene, cyclopentadiene. Not long after the Diels-Alder reaction was first reported, a series of papers disclosed the discovery of the double dehydro-Diels-Alder reaction. In this reaction a 1,5-dienyne reacts with two molar equivalents of an activated dienophile to give two new rings and up to six new stereogenic centres. This facinating reaction has been proposed to proceed by way of a cyclic allene intermediate. Despite the potential power of this reaction in synthesis, it seems to have been largely ignored in the literature. In Chapter 2 the scope, limitations, stereoselectivity and mechanism of this reaction are explored. The dendralenes are an emerging family of fundamental hydrocarbons. Dendralenes are of great interest in synthesis as they can engage in diene transmissive Diels-Alder reactions that produce polycyclic compounds with considerable stereochemical complexity. The incorporation of furans into a dendralene framework leads to a new sub-family of compounds called the furanodendralenes. The synthesis and Diels-Alder chemistry of these compounds is described in Chapter 3. Related to the furanodendralenes studied in Chapter 3 are compounds containing only furan moieties, the {u03B2}-oligofurans. Chapter 4 describes a general synthesis of the whole family of {u03B2}-furans up to eight furan units in length. Structural studies, primarily by way of X-ray crystallography, have revealed the ?-oligofurans to adopt intriguing secondary structures. That many Diels-Alder reactions exhibit endo-selectivity has been known for many years (Alder's "endo-rule"). This stereoselectivity has been ascribed to Secondary Orbital Interactions. These hypothetical stabilising interactions operate only in the endo transition state. In Chapter 5 the Diels-Alder reactions of the archetypal diene, cyclopentadiene, is studied with a range of common dienophiles, in order to quantify their endo/exo selectivities. These experimental results will serve as an important reference for computational investigations into the origins of endo-selectivity in the Diels-Alder reaction.
Gender Differences of Perceived Leadership Skills Among Saudi Students

description: The aim of this study is to examine female participation in Saudi labor market as leaders. The leadership skills with which students in Saudi universities and colleges can how educational institutions make their students career ready. However, considering the low female participation in the Saudi labor market, exploring the gender differences in leadership skills is equally crucial as the leadership skills acquired in higher education institution can significantly influence employment opportunities. In addition, the gender differences in perceived leadership skills is the fact that the social roles assigned to women in Saudi society bear great significance on how they perceive their skills, which will be discussed further in the discussion portion of this paper.

description: Yuan and Shields claim that our data-encryption protocol is entirely equivalent to a classical stream cipher utilizing no quantum phenomena. Their claim is, indeed, false. Yuan and Shields also claim that schemes similar to the one presented in Phys. Rev. Lett. 90, 227901 are not suitable for key generation. This claim is also refuted. In any event, we welcome the opportunity to clarify the situation for a wider audience.

Women's Talk about Mentoring and Socialization in Local Policies
Creators: name: Jurczak, Linda Pysher
Publisher: name: Advancing Women in Leadership Journal
Year: 2017

description: Research on mentoring and socialization in organizations determined that there are benefits to mentors, protégés, and organizations derived from these relationships (Burlew, 1991; Kram, 1983). However, previous research largely ignores mentoring and socialization at all levels of politics and political organizations and this study attempts to address this oversight. I pose questions about the extent to which women are mentored in local politics and political organizations. If they are being mentored, who is doing the mentoring? Are they being socialized into politics and political organizations and, if so, by whom? A total of nine women were interviewed and shared their experiences of mentoring and socialization in local politics. Interviewees ranged in age from the early 30s to the late 70s and from School Board to Mayor.

description: Extended Red Emission (ERE) was recently attributed to the photo-luminescence of either doubly ionized Polycyclic Aromatic Hydrocarbons (PAH$^{++}$), or charged PAH dimers. We analysed the visible and mid-infrared (mid-IR) dust emission in the North-West and South photo-dissociation regions of the reflection nebula NGC 7023.Using a blind signal separation method, we extracted the map of ERE from images obtained with the Hubble Space Telescope, and at the Canada France Hawaii Telescope. We compared the extracted ERE image to the distribution maps of the mid-IR emission of Very Small Grains (VSGs), neutral and ionized PAHs (PAH$^0$ and PAH$^+$) obtained with the Spitzer Space Telescope and the Infrared Space Observatory. ERE is dominant in transition regions where VSGs are being photo-evaporated to form free PAH molecules, and is not observed in regions dominated by PAH$^+$. Its carrier makes a minor contribution to the mid-IR emission spectrum. These results suggest that the ERE carrier is a transition species formed during the destruction of VSGs. Singly ionized PAH dimers appear as good candidates but PAH$^{++}$ molecules seem to be excluded.

description: The conditions whereby epitaxy is achieved are commonly believed to be mostly governed by misfit strain. We report on a systematic investigation of growth and interface structure of single crystalline tungsten thin films on two different metal oxide substrates, Al$_{2}$O$_{3}$ ($11\bar{2}0$) and MgO ($001$). We demonstrate that despite a significant mismatch, enhanced crystal quality is observed for tungsten grown on the sapphire substrates. This is promoted by stronger adhesion and chemical bonding with sapphire compared to magnesium oxide, along with the restructuring of the tungsten layers close to the interface. The latter is supported by ab initio calculations using density functional theory. Finally, we demonstrate the growth of magnetic heterostructures consisting of high-quality tungsten layers in combination with ferromagnetic CoFe layers, which are relevant for spintronic applications.
