Publisher: name: Advancing Women in Leadership Journal
Year: 2017

description: Support is needed for new faculty members to achieve success in the early stages of the higher education career. Women, in particular, are often left to fend for themselves when entering the academy. This sonata-form case study glimpse into a mentoring relationship will focus on the experience of a new female faculty member as she was mentored and "mother-henned" by a senior member in her department. The mentor provided the framework for open sharing about tenure and promotion expectations, the inside politics of the department, research protocols at the university, and many other supports that led to her early success in academia. A point of interest is the fact that this was a cross-race mentoring relationship.

Culture, workplace stress, and coping : a study of overseas Chinese
Creators: name: Zhang, Dan
Publisher: name: University of British Columbia
Year: 2009

description: The purpose of this study was to examine Lazarus and Folkman's (1984) stress and coping theory in the context of workplace stress and coping with a focus on the influence of personal and cultural resources on cognitive appraisal, coping strategies, and the well-being of Chinese who are currently employed in professional occupations overseas. The data were collected from a volunteer sample of 228 overseas Chinese professionals (128 men, 100 women, M age = 32.6). Participants completed three sets of questionnaires over a six-week period (2 weeks apart). Specific variables of interest included cultural, social, and personal resources (Chinese collective values, perceived social support and work support, and general self-efficacy), situational appraisals (perceived situational control and self-efficacy), ways of coping (Engagement, Disengagement, and Collective strategies), and changes in short-term outcomes (job satisfaction, somatic symptoms, and depression symptoms). Items that assessed collective ways of coping were developed for this study. Significant differences were found between men and women in this sample. As such, path analysis (LISREL VIII) was used to test the hypothesized relationships in the model separately for men and women. Based on a zero-order correlation matrix, the results for the initial hypothesized path models indicated a moderate fitting model for men and an inadequate fitting model for women. However, modified models revealed a good model fit for both men and women, X 2 (29, N=128)=32.72, p=.29, Q=1.13, RMSR=.05, GFI=.96, and CFI=. 98, and X 2 (29, N=100)=44.10, p=.04, Q=1.52, GFI=.93, RMSR-.07, and CFI=.92, respectively. The pattern of relationships (path coefficients) provide partial supports for the hypothesized model and Lazarus and Folkman's (1984) theoretical assumptions. The results of this study were consistent with those obtained by other researchers who found that coping resources are associated with coping strategies and short-term outcomes (e.g., Long, Kahn, & Schutz, 1992; Terry, Tonge, & Callan, 1995). For the men, personal resources of General Self-efficacy were positively related to control appraisal, Work Support predicted Collective coping, and Social Support was associated with a decrease in depressive symptoms. As expected, Disengagement coping was found to have a significant effect on depressive symptoms for the men. For the women, General Self-efficacy and Social Support were associated with perceived self-efficacy, and predicted an increase in job satisfaction and a decrease in depressive symptoms. Self-efficacy appraisal had negative effects on Disengagement coping. As hypothesized, Engagement coping was negatively associated with changes in somatic symptoms, and Disengagement coping predicted changes in both somatic and depressive symptoms. The results Of factor analysis supported the development of a Collective coping subscale. Implications of these results and suggestions for future research are discussed.
B meson wave function from the $B\toγlν$ decay

description: We show that the leading-power $B$ meson wave function can be extracted reliably from the photon energy spectrum of the $B\toγlν$ decay up to $O(1/m_b^2)$ and $O(α_s^2)$ uncertainty, $m_b$ being the $b$ quark mass and $α_s$ the strong coupling constant. The $O(1/m_b)$ corrections from heavy-quark expansion can be absorbed into a redefined leading-power $B$ meson wave function. The two-parton $O(1/m_b)$ corrections cancel exactly, and the three-parton $B$ meson wave functions turn out to contribute at $O(1/m_b^2)$. The constructive long-distance contribution through the $B\to V\toγ$ transition, $V$ being a vector meson, almost cancels the destructive $O(α_s)$ radiative correction. Using models of the leading-power $B$ meson wave function available in the literature, we obtain the photon energy spectrum in the perturbative QCD framework, which is then compared with those from other approaches.

description: We expand the relativistic precession model to include nonequatorial and eccentric trajectories and apply it to quasi-periodic oscillations (QPOs) in black hole X-ray binaries (BHXRBs) and associate their frequencies with the fundamental frequencies of the general case of nonequatorial (with Carter's constant, $Q\neq 0$) and eccentric ($e\neq 0$) particle trajectories, around a Kerr black hole. We study cases with either two or three simultaneous QPOs and extract the parameters \{$e$, $r_p$, $a$, $Q$\}, where $r_p$ is the periastron distance of the orbit, and $a$ is the spin of the black hole. We find that the orbits with $\left[Q=0-4\right]$ should have $e\lesssim 0.5$ and $r_p \sim 2-20$ for the observed range of QPO frequencies, where $a \in [0,1]$, and that the spherical trajectories \{$e=0$, $Q \neq0$\} with $Q=2-4$ should have $r_s \sim 3-20$. We find nonequatorial eccentric solutions for both M82 X-1 and GROJ 1655-40. We see that these trajectories, when taken together, span a torus region and give rise to a strong QPO signal. For two simultaneous QPO cases, we found equatorial eccentric orbit solutions for XTEJ 1550-564, 4U 1630-47, and GRS 1915+105, and spherical orbit solutions for BHXRBs M82 X-1 and XTEJ 1550-564. We also show that the eccentric orbit solution fits the Psaltis-Belloni-Klis correlation observed in BHXRB GROJ 1655-40. Our analysis of the fluid flow in the relativistic disk edge suggests that instabilities cause QPOs to originate in the torus region. We also present some useful formulae for trajectories and frequencies of spherical and equatorial eccentric orbits.

Disorder-induced superconductor to insulator transition and finite phase stiffness in two-dimensional phase-glass models

Subjects: subject: Superconductivity (cond-mat.supr-con)

description: We study numerically the superconductor to insulator transition in two-dimensional phase-glass (or chiral-glass) models with varying degree of disorder. These models describe the effects of gauge disorder in superconductors due to random negative Josephson-junction couplings, or $π$ junctions. Two different models are considered, with binary and Gaussian distribution of quenched disorder, having nonzero mean. Monte Carlo simulations in the path-integral representation are used to determine the phase diagram and critical exponents. In addition to the usual superconducting and insulating phases, a chiral-glass phase occurs for sufficiently large disorder, with random local circulating currents of different chiralities. A transition from superconductor to insulator can take place via the intermediate chiral-glass phase. We find, however, that the chiral-glass state has a finite phase stiffness, being still a superconductor, instead of the Bose metal, which has been suggested by mean-field theory.

description: We initiate the study of cluster algebras in Feynman integrals in dimensional regularization. We provide evidence that four-point Feynman integrals with one off-shell leg are described by a $C_{2}$ cluster algebra, and we find cluster adjacency relations that restrict the allowed function space. By embedding $C_{2}$ inside the $A_3$ cluster algebra, we identify these adjacencies with the extended Steinmann relations for six-particle massless scattering. The cluster algebra connection we find restricts the functions space for vector boson or Higgs plus jet amplitudes, and for form factors recently considered in $\mathcal{N}=4$ super Yang-Mills. We explain general procedures for studying relationships between alphabets of generalized polylogarithmic functions and cluster algebras, and use them to provide various identifications of one-loop alphabets with cluster algebras. In particular, we show how one can obtain one-loop alphabets for five-particle scattering from a recently discussed dual conformal eight-particle alphabet related to the $G(4,8)$ cluster algebra.

Procedures for the study included gathering the gender of all public school principals in the state of Texas by utilizing a TEA data bank. The 2006 AEIS report generated information regarding campus size, campus level, and campus rating for every school in the state of Texas. Results indicated that a significant relationship exists between each of the variables tested. The prevalence of gender at particular school campuses has continued, as gender was found to be significantly related to campus size, campus rating, and campus level. Discussion presented is related to hiring practices and future research.

description: In 1963 Ezra Ted Newman and his two students Louis A. Tamburino, and Theodore W. J. Unti, proposed a deformation of the Shwarzschild spacetime that made it twisting. In the cosmological context, an equivalent solution had been found earlier, in 1951, by Abraham Haskel Taub. The problem that these solutions have is a conical singularity along the symmetry axis at all distances from the origin. In 1969 Misner proposed a non-singular interpretation of Taub-NUT spacetimes. We extend and refine his method to include a broader family of solutions and completely solve the outstanding issue of a non-singular extension of the Kerr-NUT- (anti) de Sitter solutions to Einstein's equations. Our approach relies on an observation that in 2 dimensional algebra of Killing vector fields there exist 2 distinguished vector fields that may be used to define $U(1)$-principal bundle structure over the non-singular spaces of non-null orbits. For all admissible parameters we derive appropriate Killing vector fields and discuss limits to spacetimes with less parameters. The global structure of spacetime, together with non-singular conformal geometry of the infinities is presented and (possibly also projectively non-singular) Killing horizons is presented.

description: The globally increasing demand for food, fiber, and bio-based products interferes with the ability of arable soils to perform their multiple functions and support sustainable development. Sustainable soil management under high production conditions means that soil functions contribute to ecosystem services and biodiversity, natural and economic resources are utilized efficiently, farming remains profitable, and production conditions adhere to ethical and health standards. Research in support of sustainable soil management requires an interdisciplinary approach to three interconnected challenges: (i) understanding the impacts of soil management on soil processes and soil functions; (ii) assessing the sustainability impacts of soil management, taking into account the heterogeneity of geophysical and socioeconomic conditions; and (iii) having a systemic understanding of the driving forces and constraints of farmers’ decision-making on soil management and how governance instruments may, interacting with other driving forces, steer sustainable soil management. The intention of this special issue is to take stock of an emerging interdisciplinary research field addressing the three challenges of sustainable soil management in various geographic settings. In this editorial, we summarize the contributions to the special issue and place them in the context of the state of the art. We conclude with an outline of future research needs.
Superconductivity Versus Phase Separation, Stripes, and Checkerboard Ordering: A Two-Dimensional Monte Carlo Study

Subjects: subject: Superconductivity (cond-mat.supr-con)

description: Using Monte Carlo techniques, we study a simple model which exhibits a competition between superconductivity and other types of order in two dimensions. The model is a site-diluted XY model, in which the XY spins are mobile, and also experience a repulsive interaction extending to one, two, or many shells of neighbors. Depending on the strength and range of the repulsion and spin concentration, the spins arrange themselves into a remarkable variety of patterns at low temperatures $T$, including phase separation, checkerboard order, and straight or labyrinthine patterns of stripes, which sometimes show hints of nematic or smectic order. This pattern formation profoundly affects the superfluid density, $γ$. Phase separation tends to enhance $γ$, checkerboard order suppresses it, and stripe formation increases the component of $γ$ parallel to the stripes and reduces the perpendicular one. We verify that $γ(T = 0)$ is proportional to the effective conductance of a random conductance network whose conductances equal the couplings of the XY system. Possible connections between the model and real materials, such as single high-T$_c$ cuprate layers, are briefly discussed.

Structural properties and enthalpy of formation of magnesium hydride from quantum Monte Carlo calculations

description: We have used diffusion Monte Carlo (DMC) calculations to study the structural properties of magnesium hydride (MgH$_2$), including the pressure-volume equation of state, the cohesive energy and the enthalpy of formation from magnesium bulk and hydrogen gas. The calculations employ pseudopotentials and B-spline basis sets to expand the single particle orbitals used to construct the trial wavefunctions. Extensive tests on system size, time step, and other sources of errors, performed on periodically repeated systems of up to 1050 atoms, show that all these errors together can be reduced to below 10 meV per formula unit. We find excellent agreement with the experiments for the equilibrium volume of both the Mg and the MgH$_2$ crystals. The cohesive energy of the Mg crystal is found to be 1.51(1) eV, and agrees perfectly with the experimental value of 1.51 eV. The enthalpy of formation of MgH$_2$ from Mg bulk and H$_2$ gas is found to be $0.85 \pm 0.01$ eV/formula unit, or $82 \pm 1$ kJ/mole, which is off the experimental one of $76.1 \pm 1$ kJ/mole only by 6 kJ/mole. This shows that DMC can almost achieve chemical accuracy (1 kcal/mole) on this system. Density functional theory errors are shown to be much larger, and depend strongly on the functional employed.

description: The infrared absorption spectra of four Ume-aluminosihcate glasses have been studied at high temperatures in the spectral range 1 to 5 µm. The glass composition varies essentially by the FeO content. The effect of temperature is pointed out up to 1450 °C. The emission spectrometry technique used is appHed to thin slabs of semitransparent materials heated in plane-parallel platinum crucibles exposed to strong temperature gradients. The absorption coefficient is identified, for each wavelength, by a non-linear constraint optimization technique. As an illustration of the major influence of the spectrum on the heat exchanges in semitransparent devices, a modeling of the combined conductive/radiative heat transfer is performed in a glass wall.

description: We study the evolution of dynamic properties of the BCS/BEC (Bose-Einstein Condensate) crossover in a relativistic superfluid as well as its thermodynamics. We put particular focus on the change in the soft mode dynamics throughout the crossover, and find that three different effective theories describe it; these are, the time-dependent Ginzburg-Landau (TDGL) theory in the BCS regime, the Gross-Pitaevskii (GP) theory in the BEC regime, and the relativistic Gross-Pitaevskii (RGP) equation in the relativistic BEC (RBEC) regime. Based on these effective theories, we discuss how the physical nature of soft mode changes in the crossover. We also discuss some fluid-dynamic aspects of the crossover using these effective theories with particular focus on the shear viscosity. In addition to the study of soft modes, we show that the ``quantum fluctuation'' is present in the relativistic fermion system, which is in contrast to the usual Nozi`eres--Schmit-Rink (NSR) theory. We clarify the physical meaning of the quantum fluctuation, and find that it drastically increases the critical temperature in the weak coupling BCS regime.

description: Quantitative dement concentrations in titania films produced by different deposition techniques (evaporation, sputtering, ion-assisted deposition, ion plating and dip coating) have been determined by means of Rutherford Backscattering Spectrometry and Nuclear Reaction Analysis with the reaction ¹H(¹⁵N, αγ)¹²C. Large differences of the hydrogen content are found for the various production techniques and the related deposition parameters, which correlate with the refractive index of the respective film. In dependence on the deposition conditions the oxygen/titanium ratio of the investigated titania films varies between 1.95 and 2.09. The impurities detected in the films (tantalum, molybdenum, silicon, argon, carbon, sodium) can be related to specific deposition conditions. Three multilayer interference systems containing TiO₂ and SiO₂ show large variations in hydrogen content resembling those found for single TiO₂ films.

The gender composition was 131 (37.2%) male and 221 (68.2%) female and the majority of students was enrolled in 11th and 12th grades. Our findings indicated that (a) more females than males were enrolled in AP courses, (b) females perceived school support as more important than males, and (c) participation in elementary and middle school programs, such as gifted and talented programs and magnet schools were important for participation in high school AP courses. Implications for school policy are noted.

What is the experience and meaning for women in midlife of the recent death of their mothers?
Creators: name: Kranz, Karen Catharine
Publisher: name: University of British Columbia
Year: 2009

description: The purpose of this research was to explore how women in midlife experience and make meaning of the recent death of their mothers. A qualitative phenomenological paradigm was chosen as a means of exploring and discovering, in depth and in detail, midlife daughters' experiences as they viewed them from within their own phenomenological worlds (Henwood, 1993). Nine Caucasian women between the ages of 42 and 65 years participated in individual, in-depth, audio taped, personal interviews. Each of these women had experienced the death of her mother between 1 1/2 and 5 years prior to the interview. The main question the women were asked to consider and describe was: What was it like for you to experience your mother's death and what meaning does her death have for you today? Co-researchers were invited to discuss their experiences like a story with a beginning - a middle - and an end. Colaizzi's (1978) seven-step model of phenomenological data analysis served as a general guideline to identify the common themes shared by these women who had recently experienced their mothers' death. Seven themes emerged through the analysis. These themes pertained to these daughters' (1) profound sense of loss, (2) need to make sense of their mothers' death, (3) need to reassess their relationships with their mothers, (4) sense of regret concerning lost opportunities, (5) sense of shifting roles and responsibilities, (6) need to reassess meaning in their lives, and (7) sense of enduring connection to their mothers. These themes are elaborated on in terms of their implications for future research and counselling.

description: Weak invariants are time-dependent observables with conserved expectation values. Their fluctuations, however, do not remain constant in time. On the assumption that time evolution of the state of an open quantum system is given in terms of a completely positive map, the fluctuations monotonically grow even if the map is not unital, in contrast to the fact that monotonic increases of both the von Neumann entropy and Rényi entropy require the map to be unital. In this way, the weak invariants describe temporal asymmetry in a manner different from the entropies. A formula is presented for time evolution of the covariance matrix associated with the weak invariants in the case when the system density matrix obeys the Gorini-Kossakowski-Lindblad-Sudarshan equation.

Investigations into all-electric melting of neutral glass with improved reboil behaviour

Year: 1994
Subjects: subject: 660

description: With regard to chemical stability, great demands are made on neutral glasses because of their pharmaceutical application, which requires a high standard of the quality parameters: bubble numbers, homogeneity, and reboil stability. Nowadays, acceptable results are only reached by fuel-fired special furnaces with very high specific energy consumption and engineering efforts. The economical and ecological advantages of all-electric glass melting could contribute to considerable cost cutting. At present, however, certain quality criteria are not within reach when using this melting technology. The main disadvantages are the comparatively high residual gas contents and bubble numbers. Up to now, efforts have been unsuccessful to melt neutral glass with sufficient glass quality all electrically. The possible advantages, however, are worth treating this problem further. The present conception is based on a separation in melting and fining basin. By using knowledge of all-electric melting of borosilicate glass 3.3, the disadvantages in respect of gas solubility and bubble numbers will be removed in a separate fining cell by use of bubbling. Various laboratory experiments led to the concept of a combination of chemical and physical refining. The parameters for optimizing the refining process have been investigated. As a result of this work, a technical realization is proposed.

description: Although deep neural networks have been a dominant method for many 2D vision tasks, it is still challenging to apply them to 3D tasks, such as medical image segmentation, due to the limited amount of annotated 3D data and limited computational resources. In this chapter, by rethinking the strategy to apply 3D Convolutional Neural Networks to segment medical images, we propose a novel 3D-based coarse-to-fine framework to efficiently tackle these challenges. The proposed 3D-based framework outperforms their 2D counterparts by a large margin since it can leverage the rich spatial information along all three axes. We further analyze the threat of adversarial attacks on the proposed framework and show how to defense against the attack. We conduct experiments on three datasets, the NIH pancreas dataset, the JHMI pancreas dataset and the JHMI pathological cyst dataset, where the first two and the last one contain healthy and pathological pancreases respectively, and achieve the current state-of-the-art in terms of Dice-Sorensen Coefficient (DSC) on all of them. Especially, on the NIH pancreas segmentation dataset, we outperform the previous best by an average of over $2\%$, and the worst case is improved by $7\%$ to reach almost $70\%$, which indicates the reliability of our framework in clinical applications.

description: There is recent interest in finding a potential formulation for Stochastic Partial Differential Equations (SPDEs). The rationale behind this idea lies in obtaining all the dynamical information of the system under study from one single expression. In this Letter we formally provide a general Lagrangian formalism for SPDEs using the Hojman et al. method. We show that it is possible to write the corresponding effective potential starting from an s-equivalent Lagrangean, and that this potential is able to reproduce all the dynamics of the system, once a special differential operator has been applied. This procedure can be used to study the complete time evolution and spatial inhomogeneities of the system under consideration, and is also suitable for the statistical mechanics description of the problem.

description: The melting behavior of mass glass batches was studied in a gas-fired lab-scale furnace. Batches were adjusted to different redox numbers by additions of sulfate and coal. In each test, 4 kg of batch were charged onto a cullet melt (7 kg, 600 cm² surface area) which was pre-molten at 1200°C. The batch blankets had an initial height of approximately 5 cm. The vertical distribution of temperatures and electrical conductivides were recorded. The occurrence of primary melt was identified by a sudden increase of conductivity by three orders of magnitude. As expected, primary melt occurred latest in the inner zones of the batch. A comparison of conductivities and temperatures, however, showed that primary melt was not formed along any specific isotherm. Thus, the concept of a uniform melting temperature valid for the entire batch heap as used in several theoretical models is not confirmed. Thermal diffusivities derived from a numerical evaluation of the temperature field also displayed a sudden increase, however, at temperatures systematically higher than the temperatures of primary melt formation.

description: Quantum dynamics on quasiperiodic geometries has recently gathered significant attention in ultra-cold atom experiments where non trivial localised phases have been observed. One such quasiperiodic model is the so called Fibonacci model. In this tight-binding model, non-interacting particles are subject to on-site energies generated by a Fibonacci sequence. This is known to induce critical states, with a continuously varying dynamical exponent, leading to anomalous transport. In this work, we investigate whether anomalous diffusion present in the non-interacting system survives in the presence of interactions and establish connections to a possible transition towards a localized phase. We investigate the dynamics of the interacting Fibonacci model by studying real-time spread of density-density correlations at infinite temperature using the dynamical typicality approach. We also corroborate our findings by calculating the participation entropy in configuration space and investigating the expectation value of local observables in the diagonal ensemble.

"˜So Pleasant to be a School Maam': The Civil War as an Educational Force for Women
Creators: name: Bailey, Dr. Lucy E.
Publisher: name: Advancing Women in Leadership Journal
Year: 2017

description: Scrutinizing the documentary traces of women's lives reveals the significant variability in what constitutes women's leadership and advancement historically. During war time, even the act of writing a letter offered women opportunities to advance their learning. This paper draws from a collection of over 150 letters Northern women wrote during the American Civil War to consider aspects of women's educational experiences during this devastating national conflict that spanned four bloody years and involved millions of Americans (Bailey, 2008; Rhoades & Bailey, 2009). Women's historians have explored how the war shaped women's social roles, gendered consciousness, and political organizing, yet its educational implications remain an under-theorized aspect of the war's complicated legacy worth exploring further. The letters under study highlight four aspects of women's education during the American Civil War: (a) women's varied attitudes toward new opportunities to teach and attend school, (b) wartime correspondence as an educational tool, (c) home front demands as obstacles to women's pursuit of formal education; and, conversely, (d) war events as educational forces in women's lives. Each has implications for reconsidering women's leadership and advancement historically.

description: Encapsulating graphene in hexagonal Boron Nitride has several advantages: the highest mobilities reported to date are achieved in this way, and precise nanostructuring of graphene becomes feasible through the protective hBN layers. Nevertheless, subtle effects may arise due to the differing lattice constants of graphene and hBN, and due to the twist angle between the graphene and hBN lattices. Here, we use a recently developed model which allows us to perform band structure and magnetotransport calculations of such structures, and show that with a proper account of the moiré physics an excellent agreement with experiments can be achieved, even for complicated structures such as disordered graphene, or antidot lattices on a monolayer hBN with a relative twist angle. Calculations of this kind are essential to a quantitative modeling of twistronic devices.
Determination of the rheological properties of high-viscous glass melts by the cylinder compression method

description: A detailed description of the cylinder compression method and its application on the viscoelastic behaviour of glass melts is given with the help of closed solutions and equations in contrast to algorithmic methods, like e.g. the finite element method. Special attention is paid to the system deformation and system deformation rate of the testing equipment and to the dissipation of mechanical energy within the specimen and the heat flow from the specimen. The limits of this treatment are discussed with respect to the applicability of the theoretical basis (Gent and Nadai equation) and with respect to the experimental determination of the rheological properties of glass melts. On this basis the pure non-Newtonian viscosity, ηnN, can be determined. If very small differences have to be ascertained in the rheological behaviour of glass melts due to small differences in composition or in melting history (e.g. redox condition or bad/good workability), the same conditions concerning the mechanical and thermal equipment and even the same geometry of the glass specimens have to be strictly maintained. Comparison between different glass melts should be made rather on the basis of equal (Newtonian) equilibrium viscosity, η₀, (isochomal conditions) and not on equal temperature. Owing to large thermal effects, the slope of the viscosity-temperature curve at η₀ plays a certain role, particularly for the forming process.
Quasi-equilibhum in silicate glasses

Subjects: subject: 660

description: Inhomogeneity in glasses detected as a composition fluctuation with a wavelength of about 0.1 to 1.0 mm is assumed to be an inherent property of common silicate glasses caused by the circumstances of glass melting. After a single-phased melt is formed from a heterogeneous system of raw materials the component diffusion decreases the inhomogeneity This process is slowed down and practically stopped when the so-called quasi-equilibrium has been reached. In this state the chemical potendal of a given i-th component is approximately constant, i.e. µi(x,y,z) ≈ const, instead of µi{x,y,z) ≈ const, for, at least, two components. While this equation is only valid for one or two (rarely more) fixed compositions, the former one allows the coexistence of all conceivable compositions within a given range. Thus, the inhomogeneity can be preserved, especially when a long wave fluctuation prevails. The effect of the inhomogeneity on the properties of glass is emphasized.

description: Average consensus algorithms have wide applications in distributed computing systems where all the nodes agree on the average value of their initial states by only exchanging information with their local neighbors. In this letter, we look into link-based network metrics which are polynomial functions of pair-wise node attributes defined over the links in a network. Different from node-based average consensus, such link-based metrics depend on both the distribution of node attributes and the underlying network topology. We propose a general algorithm using the weighted average consensus protocol for the distributed computation of link-based network metrics and provide the convergence conditions and convergence rate analysis.

Practical strength of glass containers : Part 1. Influence of the type of defect

description: The practical strength of container glass depends not only on the stress distribution at the surface, but also on the type and distribution of surface defects. After the elimination of the influence of the container shape by means of finite element methods, different types of defect show a different behaviour in the Weibull plot. Especially seeds and blisters are shown to be twice as dangerous as inhomogeneides caused by handling materials. The accuracy of the stress determination is limited, thus, an identification of different types of inhomogeneities from the Weibull plot is not possible under the present conditions.

description: A brief review is given on the discovery and the first five decades of the Hanbury Brown - Twiss effect and its generalized applications in high energy nuclear and particle physics, that includes a meta-review. Interesting and inspiring new directions are also highlighted, including for example source imaging, lepton and photon interferometry, non-Gaussian shape analysis as well as many other new directions. Existing models are compared to two-particle correlation measurements and the so-called RHIC HBT puzzle is resolved. Evidence for a (directional) Hubble flow is presented and the conclusion is confirmed by a successful description of the pseudorapidity dependence of the elliptic flow as measured in Au+Au collisions by the PHOBOS Collaboration.

Gender and the Career Aspirations, Professional Assets, and Personal Variables of Higher Education Administrators
Creators: name: Lepkowski, Christine C.
Publisher: name: Advancing Women in Leadership Journal
Year: 2017

description: A recent national survey found women hold only 23% of higher education institution presidencies (American Council on Education, 2007). However, women now earn 58% of all bachelor's degrees and 45% of all doctorates (U.S. Department of Education, 2005). These findings suggest something may be interfering with the pool of capable women moving through the pipeline to attain higher education administrative positions. Gender differences in career aspirations, professional assets, and various personal variables have been suggested as potential contributors to this disparity. The purpose of the research was to survey women and men holding administrative positions of dean or higher (excluding presidents) within the institutions in the Minnesota State Colleges and Universities (MnSCU) system to examine these potential contributors. Based on the findings, with the exception of geographic mobility, factors other than career aspirations, professional assets, and personal variables may be the cause of barriers to female advancement to high level administrative positions.

Homogenization of glass melts by bubbling on a laboratory scale

description: In a typical melter, the molten glass tends to be inhomogeneous due to the heterogeneity of the raw materials. One means of yielding more homogeneous glass is bubbling air through the glass melt through nozzles at the base of the melter. The induced fluid flow dissolves cords and homogenizes the glass melt. This bubbling process was investigated on a laboratory scale both from an experimental and a theoretical point of view. A standard soda-lime-silica glass was bubbled with argon in a platinum crucible at 1400 C. The samples treated were tested with regard to their optical homogeneity, using an improved version of the Christiansen-Shelyubskii method. The corresponding fluid flow phenomena were simulated by a suitable mathematical model. Due to the axial symmetry of the bubbling equipment and the high viscosity of the glass melt (creeping flow), the problem can be reduced to the solution of a differential equation of the fourth order with the stream function as independent variable. The numerical treatment superposes Gegenbauer functions matching the given boundary values for the velocity and tension, respectively. The homogeneity strongly increased with bubbling time and its local variation showed good correlation with the calculated flow pattern in the crucible.
