description: Unternehmen sehen sich heute einer dynamischen Umwelt ausgesetzt. Nicht vorhergesehene Umbrüche können die Unternehmensexistenz gefährden. Zukunftsforschung ist eine Methode zur Prognose möglicher Ereignisse. Sie gewinnt an Qualität, wenn sie kooperativ durch das Wissen und die Kreativität von Menschen mit unterschiedlichsten Erfahrungen und Wissenszugängen angereichert wird. Wissen ist jedoch häufig die Basis von Wettbewerbsvorteilen und wird daher zwischen Unternehmen nur selten ausgetauscht. Dieser Beitrag beschäftigt sich mit einem IT-basierten Lösungsansatz des Kooperationsdilemmas in der Zukunftsforschung. Der Ansatz resultiert in einem technischen Konzept, welches auf integrierte Weise unternehmensübergreifendes Wissen bündelt und eine kooperative Zukunftsforschung bei gleichzeitiger Berücksichtigung von sensiblen Daten ermöglicht. Der beschriebene Ansatz wird im Dezernat Zukunftsanalyse der Bundeswehr prototypisch umgesetzt.

description: Wind lidars allow new approaches to building and operating wind plants but also generate huge amounts of data. This white paper provides a short overview of how digitalization -- the process of converting information into discoverable, shareable, and actionable computer-readable data -- could help the wind energy industry benefit from wind lidar, and what needs to be done to make this vision a reality.
Energy and directional signatures for plane quantized gravity waves

Subjects: subject: General Relativity and Quantum Cosmology (gr-qc)

description: Solutions are constructed to the quantum constraints for planar gravity (fields dependent on z and t only) in the Ashtekar complex connection formalism. A number of operators are constructed and applied to the solutions. These include the familiar ADM energy and area operators, as well as new operators sensitive to directionality (z+ct vs. z-ct dependence). The directionality operators are quantum analogs of the classical constraints proposed for unidirectional plane waves by Bondi, Pirani, and Robinson (BPR). It is argued that the quantum BPR constraints will predict unidirectionality reliably only for solutions which are semiclassical in a certain sense. The ADM energy and area operators are likely to have imaginary eigenvalues, unless one either shifts to a real connection, or allows the connection to occur other than in a holonomy. In classical theory, the area can evolve to zero. A quantum mechanical mechanism is proposed which would prevent this collapse.

description: Osteoblasts are bone-forming cells and therefore they are responsible of the synthesis of type I collagen, the main component of bone matrix. However, there is an apparent disconnect between the regulation of osteoblast differentiation and bone formation since the synthesis of Type I collagen precedes the expression of Runx2, the earliest determinant of osteoblast differentiation. Recently, genetic experiments in the mouse have revealed the existence of an unexpected cross-regulation between bone and other organs. In particular this body of work has highlighted the importance of osteoblasts as endocrine cells to regulate whole-body glucose homeostasis by secretion of a hormone, osteocalcin. However, the fundamental question of why bone regulates glucose homeostasis remained to be answered. Therefore, in my thesis, considering that bone is a metabolically demanding organ that constantly renews itself, I hypothesized that characterizing the connection between the need of glucose as a main nutrient in osteoblasts and bone development will provide a key to deeper understanding of why bone regulates glucose homeostasis.
      My work shows here that glucose uptake through GLUT1 in osteoblasts is needed for osteoblast differentiation by suppressing the AMPK-dependent activation by phosphorylation at S148 of Smurf1 that targets Runx2 for degradation. I also uncovered the mechanism of action of Smurf1 in this setting. In a distinct but synergetic way, glucose uptake promotes bone formation by inhibiting a distinct function of AMPK. In turn, Runx2 favors Glut1 expression, and this feedforward regulation between Runx2 and Glut1 determines the onset of osteoblast differentiation during development and the extent of bone formation throughout life.
      Furthermore, I also identified that Smurf1 not only regulates osteoblast differentiation by targeting Runx2 for degradation but also contributes to whole-body glucose homeostasis by regulating the activation of osteocalcin by targeting the insulin receptor for degradation in vivo. These results identify Smurf1 as a determinant of osteoblast differentiation during development, of bone formation and glucose homeostasis post-natally. Most importantly, we show that these Smurf1 functions required AMPK-phosphorylation site S148 in vivo.
      Altogether, these results revealed the absolute necessity of glucose as a regulator of Runx2 accumulation during osteoblast differentiation and bone formation in vivo and highlight the fundamental importance of the intricate cross-talk between bone and whole-body glucose metabolism.

description: We use a novel method of computing the third moment M_3 of the action of the 2+1-dimensional compact Higgs model in the adjoint representation with q=2 to extract correlation length and specific heat exponents nu and alpha, without invoking hyperscaling. Finite-size scaling analysis of M_3 yields the ratio (1+alpha)/nu and 1/nu separately. We find that alpha and nu vary along the critical line of the theory, which however exhibits a remarkable resilience of Z_2 criticality. We propose this novel universality class to be that of the quantum phase transition from a Mott-Hubbard insulator to a charge-fractionalized insulator in two spatial dimensions.

description: We study quantum quench dynamics in the Fermi-Hubbard model, and its SU($N$) generalizations, in one-dimensional lattices in the limit of infinite onsite repulsion between all flavors. We consider families of initial states with generalized Neel order, namely, initial state in which there is a periodic $N$-spin pattern with consecutive fermions carrying distinct spin flavors. We introduce an exact approach to describe the quantum evolution of those systems, and study two unique transient phenomena that occur during expansion dynamics in finite lattices. The first one is the dynamical emergence of Gaussian one-body correlations during the melting of sharp (generalized) Neel domain walls. Those correlations resemble the ones in the ground state of the SU($N$) model constrained to the same spin configurations. This is explained using an emergent eigenstate solution to the quantum dynamics. The second phenomenon is the transformation of the quasimomentum distribution of the expanding strongly interacting SU($N$) gas into the rapidity distribution after long times. Finally, we study equilibration in SU($N$) gasses and show that observables after equilibration are described by a generalized Gibbs ensemble. Our approach can be used to benchmark analytical and numerical calculations of dynamics of strongly correlated SU($N$) fermions at large $U$.

description: Methods for conventional treatment of mine effluent are often costly and, in some cases, ineffective at meeting environmental water quality objectives. Microbially-mediated reduction and biotransformation of inorganic contaminants in mine-impacted water (MIW) can provide an innovative and cost-effective solution. This presentation will discuss two geochemical systems: anaerobic treatment of selenium and nitrate; and anaerobic treatment of sulphate and metals. One type of technology in which these processes can be implemented is a semi-passive biotreatment reactor called a Gravel Bed Reactor (GBR™). A GBR is an engineered biochemical reactor that has been proven to effectively decrease concentrations of metals, metalloids, other inorganics such as nitrate or sulphate, and organic chemicals through microbial and geochemical processes. The chemistry of MIW can vary widely including highly acidic or alkaline pH and elevated and variable concentrations of metals and inorganics. The ability to understand and control the target microbial and geochemical processes, and to adapt to influent chemistry are important considerations in designing and achieving long-term effective performance using biological treatment systems. This presentation will discuss the considerations and opportunities to applying microbial remediation as an innovative and cost-effective treatment technology at Canadian mine sites.

description: In this paper we sketch out a two-way-path from the general definition of collective intelligence to the specific usage of collective intelligence in ‘corporate web 2.0’ and back again. On the one hand we argue for a better formal underpinning of the connection of micro-level activities and macro-level emergents in the context of collective intelligence. On the other hand we reason that explicit consideration of examples from the web 2.0 in the discussion of collective intelligence will lead to better models of collective intelligence if done systematically. We propose a first step towards a model that could help to understand emergence and individual motivation in collective intelligence systems.

description: Dynamical Lie-algebraic method for the construction of local quantum invariants of motion in non-integrable many-body systems is proposed and applied to a simple but generic toy model, namely an infinite kicked $t-V$ chain of spinless fermions. Transition from integrable via {pseudo-integrable (\em intermediate}) to quantum ergodic (quantum mixing) regime in parameter space is investigated. Dynamical phase transition between ergodic and intermediate (neither ergodic nor completely integrable) regime in thermodynamic limit is proposed. Existence or non-existence of local conservation laws corresponds to intermediate or ergodic regime, respectively. The computation of time-correlation functions of typical observables by means of local conservation laws is found fully consistent with direct calculations on finite systems.

Boson Stars in General Scalar-Tensor Gravitation: Equilibrium Configurations

Publisher: name: arXiv
Year: 1997
Subjects: subject: General Relativity and Quantum Cosmology (gr-qc)
subject: FOS: Physical sciences

description: We study equilibrium configurations of boson stars in the framework of general scalar-tensor theories of gravitation. We analyse several possible couplings, with acceptable weak field limit and, when known, nucleosynthesis bounds, in order to work in the cosmologically more realistic cases of this kind of theories. We found that for general scalar-tensor gravitation, the range of masses boson stars might have is comparable with the general relativistic case. We also analyse the possible formation of boson stars along different eras of cosmic evolution, allowing for the effective gravitational constant far out form the star to deviate from its current value. In these cases, we found that the boson stars masses are sensitive to this kind of variations, within a typical few percent. We also study cases in which the coupling is implicitly defined, through the dependence on the radial coordinate, allowing it to have significant variations in the radius of the structure.

Theory of generalized and classical Massey products and a general construction of symplectic manifolds with nontrivial Massey products of arbitrary large order are exposed. The construction uses the symplectic blow-up and is based on the author results, which describe conditions under which the blow-up of a symplectic manifold X along its submanifold Y inherits nontrivial Massey products from X ot Y. This gives a general construction of nonformal symplectic manifolds.

description: It has been proposed to make practical use of chaos in communication, in enhancing mixing in chemical processes and in spreading the spectrum of switch-mode power suppies to avoid electromagnetic interference. It is however known that for most smooth chaotic systems, there is a dense set of periodic windows for any range of parameter values. Therefore in practical systems working in chaotic mode, slight inadvertent fluctuation of a parameter may take the system out of chaos. We say a chaotic attractor is robust if, for its parameter values there exists a neighborhood in the parameter space with no periodic attractor and the chaotic attractor is unique in that neighborhood. In this paper we show that robust chaos can occur in piecewise smooth systems and obtain the conditions of its occurrence. We illustrate this phenomenon with a practical example from electrical engineering.

description: Teck Coal retained the services of Lotic Environmental, MN Gaboury, and Kerr Wood Leidal to design the Fording River Habitat Rehabilitation near Concrete Arch Bridge offsetting measure required as part of Teck’s Line Creek Phase II mine extension fish habitat offsetting plan. The design team employed a natural channel design process to develop the rehabilitation design. This approach used regional relationships of channel morphology-vs-drainage area and channel metrics from undisturbed reaches as a natural template to identify channel metrics and processes assumed to be outside of what would be expected for a natural site. A design was developed with specific treatments to promote an accelerated recovery of habitat quality over time, allowing the river to repair itself. Channel width-to-depth ratio, percent pools, and woody debris abundance were key aspects targeted for rehabilitation. Rehabilitation treatments were completed in fall 2016 and included 27 instream jams and 103 bar top structures in 1,280 m of channel. Two meander bends were reconstructed, each with riffle structures to provide bed stability. Bioengineering was completed in spring 2019. Year 3 (2019) represented the first full post-construction effectiveness monitoring of habitat and fish use. Results suggest that the target habitat features were beginning to develop.

description: Purpose: Gamma radiation is mainly used for disinfesting insect pests as an alternative for harmful fumigants. The specific dose of radiation is known to affect different developmental stages of insect pests. The study was conducted to determine the effective irradiation doses for inhibition of developmental stages and adult longevity of the coffee berry borer, Hypothenemus hampei (Ferrari). Materials and methods: Irradiation was carried with the following doses: five levels between 0.01 and 0.16 kGy for eggs, seven levels between 0.10 and 2.00 kGy for larva and prepupa, six levels between 0.10 and 1.60 kGy for pupa and ten levels between 0.10 and 3.20 kGy for adults. Results: Egg development was completely arrested at 0.160 kGy. A dose of 2.00 kGy caused 100% mortality in the first and second instar larva and 98.99% mortality in prepupa. The dose of 1.60 kGy prevented adult eclosion from the irradiated pupa. The adult mortality was 100% at 3.20 kGy. Conclusion: A dose of 3.20 kGy could successfully provide complete security from all developmental stages of H. hampei and prevent yield loss in green coffee as well as the spread of the pest. Mortality rate of egg, larva, prepupa, pupa and adult of Hypothenemus hampei at different doses of radiation.

description: Nachdem Photonenströme bzw. einzelne Photonen mit hoher zeitlicher Auflösung durch Photonendetektoren quantitativ erfaßt werden können, haben Theorie und Praxis der Autokorrelationsanalyse der Strahlungssignale eine wachsende Bedeutung erhalten. Einerseits prägt sich hier das Fundamentalverständnis der „Quantenoptik“ aus, andererseits bieten sich damit spezielle Möglichkeiten einer spektral sehr hoch auflösenden „Korrelationsspektroskopie“. Überdies lassen sich aus einer experimentell erhaltenen Autokorrelationsfunktion (AKF) weitergehende Rückschlüsse auf die Qualität der Strahlungsquelle und/oder die Wechselwirkung der Photonen mit der durchstrahlten Materie ziehen.
Die Arbeit befaßt sich mit der Computer-gestützten Modellierung von Photonenströmen, wobei verschiedene theoretische Ansätze zur zeitlichen Abfolge der Photonen zu symptomatisch verschiedenen Zeitfunktionen führen, die entsprechend charakteristische statistische Schwankungen enthalten. Die anhand solcher „Modell-Photoströme“ ermittelten spezifischen Typen der AKF erlauben durch Vergleich mit experimentellen Resultaten deren weitergehende qualitative und u. U. auch quantitative Interpretation. – Innerhalb dieser Thematik ist auch das „Inversenproblem“ anzusprechen, d.h. die Frage nach der Möglichkeit eines eindeutigen Rückschlusses von der AKF auf eine bestimmte Zeitfunktion bzw. Statistik des vorliegenden Photonenstromes zu erörtern. Dabei ist u. a. auch zu berücksichtigen, daß die die Autokorrelation bestimmende Zeitfunktion der Photonenabfolge und die statistische Häufigkeitsverteilung der innerhalb der Samplingzeit des Detektors erfaßten Photonenanzahl unabhängig voneinander variieren können.
Nach referierenden Ausführungen zu Grundlage und Computer-gestützter Realisierung der Autokorrelationsanalyse (AKA) von Photonenströmen, sowie zur Photonenstatistik bzw. zum Photonenrauschen beim Emissionsprozess unterschiedlicher Lichtquellen bzw. nach dem Durchgang von Licht durch Materie, werden sodann im Sinne der Zielsetzung der vorliegenden Arbeit eine Reihe charakteristischer Photonenströme berechnet und der AKA unterworfen. Die Modelle erfassen dabei die zeitlich-statistische Abfolge bzw. die Häufigkeitsverteilung der Einzelphotonen, das sukzessive Auftreten von Photonen-“Pulks“ bestimmter „Form“ und die Existenz eines Photonen-“Gleichstroms“ mit überlagerten statistischen Schwankungen. Bei den erhaltenen Typen der AKF finden sich exponentiell oder Gauß-förmig relaxierende, oszillatorische und gedämpft oszillierende Anteile in spezifischer Überlagerung, deren Auftreten im Einzelfall begründend diskutiert wird.

description: In eukaryotic cells, DNA wraps around histones to form nucleosomes, which are the basic units of chromatin. Chromatin is classified as active euchromatin or repressive heterochromatin, depending on the modifications on histones and DNA. Heterochromatin, which is defined by the presence of histone modifications such as H3K9 methylation, serves important functions in cells such as silencing transposable elements, preventing aberrant recombination, and regulating gene expression.The fission yeast, which shares basic chromatin modification pathways with higher eukaryotes, is a premier model system for study heterochromatin formation. One important heterochromatin regulator is the JmjC-domain protein Epe1. It contains a conserved JmjC domain, which is commonly found in active demethylases. Despite that no in vitro demethylase activity has been demonstrated, Epe1 has been regarded as an H3K9 demethylase based on genetic evidence. However, the mechanism of its regulation is unclear at the beginning of my studies. In this thesis, I investigated the regulation of Epe1 through an unbiased genetic screen to identify factors important for Epe1 functions. From the screen, I identified multiple subunits within a transcriptional coactivator SAGA complex. I determined that Epe1 physically recruits SAGA to heterochromatin to promote histone acetylation and transcription, which provides a mechanism for a long-standing paradox regarding heterochromatin at repetitive DNA elements: heterochromatin normally represses transcription but the formation of heterochromatin requires transcription of the repeats. While past results suggest a role of Epe1 in promoting transcription of repeats, our results demonstrate how Epe1 promotes transcription. From this screen, I also identified multiple genes in the cAMP signaling pathway that are important for Epe1 function. I demonstrated that the cAMP signaling pathway regulates Epe1 protein levels post-transcriptionally, and this effect was also seen in cells experiencing glucose starvation, which dampens the cAMP signaling. This study uncovers another layer of control of Epe1 and provides a critical link between nutrient conditions and heterochromatin regulation. Altogether, my studies identified both a mechanism by which Epe1 promotes transcription within heterochromatin and a layer of Epe1 regulation by the glucose-sensing cAMP signaling pathway. These results will help future studies on Epe1 functions and how it is involved in epigenetic adaptation to changing nutrient conditions.

description: We show, through analytic arguments, numerical calculations, and comparison with experimental data, that the ratio of the high-p_T observables v_2/(1-R_AA) reaches a well-defined saturation value at high p_T, and that this ratio depends only on the spatial anisotropy of the quark gluon plasma (QGP) formed in ultrarelativistic heavy-ion collisions. With expected future reduction of experimental errors, the anisotropy extracted from experimental data will further constrain the calculations of initial particle production in heavy-ion collisions and thus test our understanding of QGP physics.

Engagement Practices Of Mason Composition Faculty As Perceived By Their Students
Creators: name: Meeks, Kathryn Marie
name: Staudt, Emily R C
Publisher: name: Innovations in Teaching & Learning Conference Proceedings
Year: 2019

description: Location: Dewberry Hall We will discuss the results from our survey of Mason Composition students, which sought to answer the question: "How do writing teachers engage students?" Our survey asked students to think of a positive instruction experience and answer questions about that experience. Though it included several questions which are similar to a teaching evaluation survey, our respondents were not asked to rate their instructor; instead, they reported on their engagement in class and their instructor's practices.

description: We present an overview of the temperature, field and angular dependence of the irreversible magnetization of non-magnetic borocarbides (Y;Lu) Ni_2 B_2 C. We show that nonlocal electrodynamics influences pinning via the unusual behavior of the shear modulus in non-hexagonal lattices. On top of that, we observe that the pinning force density F_p exhibits a rich anisotropic behavior that sharply contrasts with its small mass anisotropy. When $H \bot c$, F_p is much larger and has a quite different H dependence, indicating that other pinning mechanisms are present.

description: Explicitly representing a business model facilitates the understanding, analysis, and innovation of its underlying logic. For representing business models, numerous approaches have been suggested in the literature. They differ greatly in their understanding of the business model concept, the approach for representation, the terminology, and the notational elements they use. This impedes the diffusion of the representational approaches in business practice and the development of a cumulative research tradition. Our contributions are twofold: Based on a comprehensive literature review, we provide (I) a synthesizing framework for classifying approaches for business model representation, and (II) a terminological and conceptual synthesis of the notational elements. Thereby, practitioners are supported in selecting the most suitable representation for a specific purpose. For researchers, our work provides the basis to develop a more cumulative stream of research.

Regulation of splicing networks in neurodevelopment

description: Alternative splicing of pre-mRNA is a critical mechanism for enabling genetic diversity, and is a carefully regulated process in neuronal differentiation. RNA binding proteins (RBPs) are developmentally expressed and physically interact with RNA to drive specific splicing changes. This work tests the hypothesis that RBP-RNA interactions are critical for regulating timed and coordinated alternative splicing changes during neurodevelopment and that these splicing changes are in turn part of major regulatory mechanisms that underlie morphological and functional maturation of neurons. I describe our efforts to identify functional RBP-RNA interactions, including the identification of previously unobserved splicing events, and explore the combinatorial roles of multiple brain-specific RBPs during development. Using integrative modeling that combines multiple sources of data, we find hundreds of regulated splicing events for each of RBFOX, NOVA, PTBP, and MBNL. In the neurodevelopmental context, we find that the proteins control different sets of exons, with RBFOX, NOVA, and PTBP regulating early splicing changes and MBNL largely regulating later splicing changes. These findings additionally led to the observation that CNS and sensory neurons express a variety of different RBP programs, with many sensory neurons expressing a less mature splicing pattern than CNS neurons. We also establish a foundation for further exploration of neurodevelopmental splicing, by investigating the regulation of previously unobserved splicing events.
Static, massive fields and vacuum polarization potential in Rindler space

Subjects: subject: General Relativity and Quantum Cosmology (gr-qc)
subject: FOS: Physical sciences

description: In Rindler space, we determine in terms of special functions the expression of the static, massive scalar or vector field generated by a point source. We find also an explicit integral expression of the induced electrostatic potential resulting from the vacuum polarization due to an electric charge at rest in the Rindler coordinates. For a weak acceleration, we give then an approximate expression in the Fermi coordinates associated with the uniformly accelerated observer.

Check Your Course's Pulse: Continuous Feedback Methods
Creators: name: Middle, Beverly
name: Guingab, Terri Ann
Publisher: name: Innovations in Teaching & Learning Conference Proceedings
Year: 2019

description: Location: JC Room G Presenters will demonstrate two methods of receiving course feedback from students. In the first method, presenters distribute notebooks throughout the classroom. Students are invited to write feedback and ask questions without disrupting class flow. Students may submit feedback in the notebook anonymously. The second method uses a Qualtrics survey to conduct a mid-semester course review. Presenters will discuss best practices for eliciting constructive criticism from students, and fostering a culture of student/faculty collaboration through this activity. Both feedback methods allow students to provide feedback on teaching methods, amount and difficulty of content, course presentation, and general classroom culture. The feedback allows faculty to make mid-course adjustments to improve their instruction and better facilitate learning. Eliciting feedback from students allows faculty to model the professional behavior of receiving and responding to feedback. Providing opportunities for continuous student feedback allows students to take responsibility for their learning.

description: Phase separation in binary and ternary fluids is studied using a two dimensional Lattice Gas Automata. The lengths, given by the the first zero crossing point of the correlation function and the total interface length is shown to exhibit power law dependence on time. In binary mixtures, our data clearly indicate the existence of a regime having more than one length scale where the coarsening process proceeds through the rupture and reassociation of domains. In ternary fluids; in the case of symmetric mixtures there exists a regime with a single length scale having dynamic exponent 1/2, while in asymmetric mixtures our data establish the break down of scale invariance.

description: A conjecture connecting Lyapunov exponents of coupled map lattices and the node theorem is presented. It is based on the analogy between the linear stability analysis of extended chaotic states and the Schrödinger problem for a particle in a disordered potential. As a consequence, we propose an alternative method to compute the Lyapunov spectrum. The implications on the foundation of the recently proposed ``chronotopic approach'' are also discussed.

description: We describe generally deformed Heisenberg algebras in one dimension. The condition for a generalized Leibniz rule is obtained and solved. We analyze conditions under which deformed quantum-mechanical problems have a Fock-space representation. One solution of these conditions leads to a q-deformed oscillator already studied by Lorek et al., and reduces to the harmonic oscillator only in the infinite-momentum frame. The other solution leads to the Calogero model in ordinary quantum mechanics, but reduces to the harmonic oscillator in the absence of deformation.

description: SESSION LOCATION: George's (3rd Floor of Johnson Center) Four university partners (the University Libraries' Teaching & Learning Team, Learning Services, the Writing Center, and the Communications Center) leveraged their unique skills and expertise to provide students with a comprehensive, week-long research workshop series called "Research Your Way to An A." This timely series was meant to equip students with necessary research and life skills during one of the most critical points in the semester and in their academic careers. Our lightning talk focuses on the origins of the cross-campus partnership, the details of the outreach event, and lessons learned. It also features the results of the workshop series, including data on the number and type of students attracted as well as student-generated data rating the space, food, instruction, topics, and timeliness of the workshops. We hope to provide faculty and staff with a model for forging valuable partnerships as well as suggestions for how to make similar outreach events successful. We also hope to generate a conversation about other types of workshops that might help our undergraduate and graduate populations develop transferable skills to be used both inside and outside of the classroom.
