Computer Simulation Of Glioma Growth And Morphology, Hermann B. Frieboes, John S Lowengrub, S Wise, X Zheng, Paul Macklin, Elaine L. Bearer, Vittorio Cristini

Faculty, Staff and Student Publications

Despite major advances in the study of glioma, the quantitative links between intra-tumor molecular/cellular properties, clinically observable properties such as morphology, and critical tumor behaviors such as growth and invasiveness remain unclear, hampering more effective coupling of tumor physical characteristics with implications for prognosis and therapy. Although molecular biology, histopathology, and radiological imaging are employed in this endeavor, studies are severely challenged by the multitude of different physical scales involved in tumor growth, i.e., from molecular nanoscale to cell microscale and finally to tissue centimeter scale. Consequently, it is often difficult to determine the underlying dynamics across dimensions. New techniques …

Student Pilots Model Code Of Conduct, Aviators Code Initiative

Student Pilots Model Code of Conduct

The STUDENT PILOTSMODEL CODE OF CONDUCT (Code of Conduct) is not a standard and is not intended to be implemented as one. Instead, the Code of Conduct presents a vision of excellence for student pilots (whether they are seeking a Sport Pilot, Recreational Pilot, or Private Pilot certificate). Its principles complement and underscore legal requirements.

Structure And Biosynthesis Of Heat-Stable Antifungal Factor (Hsaf), A Broad-Spectrum Antimycotic With A Novel Mode Of Action, Fengan Yu, Kathia Zaleta-River, Xiangcheng Zhu, Justin Huffman, Jeffrey C. Millet, Steven D. Harris, Gary Y. Yuen, Xing-Cong Li, Liangcheng Du

Department of Chemistry: Faculty Publications

A screen for antifungal compounds from Lysobacter enzymogenes strain C3, a bacterial biological control agent of fungal diseases, has previously led to the isolation of heat-stable antifungal factor (HSAF). HSAF exhibits inhibitory activities against a wide range of fungal species and shows a novel mode of antifungal action by disrupting the biosynthesis of a distinct group of sphingolipids. We have now determined the chemical structure of HSAF, which is identical to that of dihydromaltophilin, an antifungal metabolite with a unique macrocyclic lactam system containing a tetramic acid moiety and a 5,5,6-tricyclic skeleton. We have also identified the genetic locus responsible …

Structure And Magnetic Properties Of Mn-Doped Zno Thin Films, Jun Zhang, Xingzhong Li, J. Shi, Yongfeng Lu, David J. Sellmyer

David Sellmyer Publications

We report the structure and magnetic properties of Zn_1-xMn_xO thin films grown on Si(001) substrates by pulsed laser deposition. Structure and phase evolution with Mn doping has been studied using x-ray diffraction, electron diffraction, and high-resolution electron microscopy. The undoped and 1% Mn-doped ZnO films are completely (001) oriented, and further Mn doping deteriorates the (001) orientation. For Mn concentrations below 3%, only the hexagonal ZnO phase exists in the films without secondary phases. As the Mn concentration reaches 5%, secondary phase Mn₂O₃ was found aggregating at grain boundaries. All the Mn-doped films …

Gev-Scale Electron Acceleration In A Gas-Filled Capillary Discharge Waveguide, Stefan Karsh, J. Osterhoff, A. Popp, T.P. Rowlands-Ree, Zs. Major, Matthias Fuchs, B. Marx, R. Horlein, K. Schmid, Laszlo Veisz, S. Becker, U. Schramm, B. Hidding, G. Pretzler, D. Habs, F. Gruner, F. Krausz, Simon M. Hooker

Matthias Fuchs Publications

We report experimental results on laser-driven electron acceleration with low divergence. the electron beam was generated by focusing 750 mJ, 42 fs laser pulses into a gas-filled capillary discharge waveguide at electron densities in the range between 10¹⁸ and 10¹⁹ cm^-3/ Quasi-monoenergentic electron bunches with energies as high as 500 MeV have been detected, with features reaching up to 1 GeV, albeit with large shot-to-shot fluctuations. A more stable regime with higher bunch charge (20-45 pC) and less energy (200-300 MeV) could also be observed. The beam divergence and the pointing stability are around or below …

Planar Hall Effect In Epitaxial Thin Films Of Magnetite, Y. Bason, L. Klein, H. Q. Wang, J. Hoffman, X. Hong, V. E. Henrich, C. H. Ahn

Xia Hong Publications

We measured the planar Hall effect (PHE) of magnetite (Fe₃O₄) films between 150 and 350 K. The PHE was measured both with a constant magnetic field rotating in the plane of the sample and in a remanent state after applying a field in specific directions. The PHE amplitude decreases with temperature; however, it changes little between 300 and 350 K. The remanent PHE signal is as high as 10 V/A, larger than previously observed in manganite films. We also measured the PHE in the remanent state and found that its magnitude and stability make it a …

Black Walnut, Charles Michler, Keith Woeste, Paula Pijut

United States Department of Agriculture, Forest Service / University of Nebraska-Lincoln: Faculty Publications

Black walnut (Juglans nigra L.), also known as eastern black walnut or American walnut, is a fine hardwood species in the family Juglandaceae, section Rhysocaryon (Manning 1978). In general, J. nigra will not cross with species in the sections Cardiocaryon or Trachycaryonv, but J. nigra will cross with J. ailantifolia (Cardiocaryon) (Williams 1990). Juglans nigra will also hybridize to some extent with other Juglans species (Dioscaryon and Rhysocaryon), and one hybrid is recognized: J. nigra × J. regia = J. x intermedia Carr. (USDA-NRCS 2004). Native to the deciduous forests of the eastern United States …

Survey Of Selected Pathogens And Blood Parameters Of Northern Yellowstone Elk: Wolf Sanitation Effect Implications, Shannon M. Barber-Meyer, P. J. White, L. David Mech

United States Geological Survey, Northern Prairie Wildlife Research Center: Publications

The restoration or conservation of predators could reduce seroprevalences of certain diseases in prey if predation selectively removes animals exhibiting clinical signs. We assessed disease seroprevalences and blood parameters of 115 adult female elk (Cervus elaphus) wintering on the northern range of Yellowstone National Park [YNP] during 2000– 2005 and compared them to data collected prior to wolf (Canis lupus) restoration (WR) in 1995 and to two other herds in Montana to assess this prediction. Blood parameters were generally within two standard deviations of the means observed in other Montana herds (Gravelly-Snowcrest [GS] and Garnet Mountain …

Protecting Soil And Water In Forest Road Management, J. M. Grace Iii, B. D. Clinton

United States Department of Agriculture, Forest Service / University of Nebraska-Lincoln: Faculty Publications

The National Forest road system is the network that supports public recreation, which has become the primary use of the public lands. The pattern of use of National Forest roads for recreation has increased dramatically since the late 1940s and is expected to continue to increase beyond the rates observed today. However, research over the past 60 years clearly presents forest roads as a major source of sediment and soil erosion from forest watersheds. Threats to healthy forests have received increased attention in the past decade. In particular, roads, road management, and travel management will likely be critical to addressing …

Delivering The Science Synthesis: Fuelstools, Anne Black, Susan Perin

United States Department of Agriculture, Forest Service / University of Nebraska-Lincoln: Faculty Publications

To facilitate delivery and use of the Fuels Planning: Science Synthesis and Integration Project’s (Project) products, the Project team engaged in a series of technology transfer activities throughout the life of the project. These included bringing land managers into the design and development phase, funding and staffing a specific delivery phase, and conducting an external evaluation to focus future activities. Our plans were informed by concepts central to the diffusion of the innovation theory; in turn, our activities deepened our understanding of the theory and its application to fuels management.

Estimating Water Storage Capacity Of Existing And Potentially Restorable Wetland Depressions In A Subbasin Of The Red River Of The North, Robert A. Gleason, Brian A. Tangen, Murray K. Laubhan, Kevin E. Kermes, Ned H. Euliss Jr.

United States Geological Survey, Northern Prairie Wildlife Research Center: Publications

Concern over flooding along rivers in the Prairie Pothole Region has stimulated interest in developing spatially distributed hydrologic models to simulate the effects of wet¬land water storage on peak river flows. Such models require spatial data on the storage volume and interception area of existing and restorable wetlands in the watershed of interest. In most cases, information on these model inputs is lacking because resolution of existing topographic maps is inadequate to estimate volume and areas of existing and restorable wetlands. Consequently, most studies have relied on wetland area to volume or interception area relationships to estimate wetland basin storage …

C-Fos As A Proapoptotic Agent In Trail-Induced Apoptosis In Prostate Cancer Cells, Xiaoping Zhang, Liang Zhang, Hongmei Yang, Xu Huang, Hasan H. Otu, Towia A. Libermann, William C. Dewolf, Roya Khosravi-Far, Aria F. Olumi

Department of Electrical and Computer Engineering: Faculty Publications

Tumor necrosis factor–related apoptosis-inducing ligand (TRAIL)/Apo-2L promotes apoptosis in cancer cells while sparing normal cells. Although many cancers are sensitive to TRAIL-induced apoptosis, some evade the proapoptotic effects of TRAIL. Therefore, differentiating molecular mechanisms that distinguish between TRAIL-sensitive and TRAIL-resistant tumors are essential for effective cancer therapies. Here, we show that c-Fos functions as a proapoptotic agent by repressing the antiapoptotic molecule c-FLIP(L). c-Fos binds the c-FLIP(L) promoter, represses its transcriptional activity, and reduces c-FLIP(L) mRNA and protein levels. Therefore, c-Fos is a key regulator of c-FLIP(L), and activation of c-Fos determines whether a cancer cell will undergo cell death …

Serum Proteome Profiling Detects Myelodysplastic Syndromes And Identifies Cxc Chemokine Ligands 4 And 7 As Markers For Advanced Disease, Manuel Aivado, Dimitrios Spentzos, Ulrich Germing, Gil Alterovitz, Xiao-Ying Meng, Franck Grall, Aristoteles A. N. Giagounidis, Giannoula Klement, Ulrich Steidl, Hasan H. Otu, Akos Czibere, Wolf C. Prall, Christof Iking-Konert, Michelle Shayne, Marco F. Ramoni, Norbert Gattermann, Rainer Haas, Constantine S. Mitsiades, Eric T. Fung, Towia A. Libermann

Myelodysplastic syndromes (MDS) are among the most frequent hematologic malignancies. Patients have a short survival and often progress to acute myeloid leukemia. The diagnosis of MDS can be difficult; there is a paucity of molecular markers, and the pathophysiology is largely unknown. Therefore, we conducted a multicenter study investigating whether serum proteome profiling may serve as a noninvasive platform to discover novel molecular markers for MDS. We generated serum proteome profiles from 218 individuals by MS and identified a profile that distinguishes MDS from non-MDS cytopenias in a learning sample set. This profile was validated by testing its ability to …

“Heritage Rocks”: Principles And Best Practices Of Effective Intercultural Teaching And Learning, Peter Frederick, Mary James

To Improve the Academy: A Journal of Educational Development

This portrayal of the intercultural teaching/learning culture and classroom stories at one fully multicultural institution, Heritage University, itself reflecting many diverse “heritages,” provides a glimpse into the faces of the future of higher education in America. We offer several examples and a synthesis of the principles and best practices of effective intercultural teaching and learning, with the intention of helping other institutions move intercultural education from the margins to the “center,” thereby preparing both teachers and learners for effective intercultural learning and living in the 21st century.

In The Eye Of The Storm: Students' Perceptions Of Helpful Faculty Actions Following A Collective Tragedy, Therese A. Huston, Michele Dipietro

To Improve the Academy: A Journal of Educational Development

On occasion, our campus communities are shaken by national tragedies such as Hurricane Katrina and the terrorist attacks of September 11, 2001, or by local tragedies such as the murder of a faculty member or student. Because these are unusual circumstances, faculty are often initially confused about how to respond, and later have little or no sense of how effective their actions have been (DiPietro, 2003). This chapter investigates the most common instructor responses following a tragedy and which of those responses students find most helpful. Implications for faculty and faculty developers are discussed.

Faculty Development In Student Learning Communities: Exploring The Vitality Of Mid–Career Faculty Participants, Shari Ellertson, John H. Schuh

To Improve the Academy: A Journal of Educational Development

Student learning communities result in numerous benefits for students and institutions, but less is known about the influence of learning community participation on faculty renewal and development. This qualitative study examines mid-career faculty members’ involvement in student learning communiities to explore the degree to which the construct of vitality appropriately describes and illuminates their experiences. Findings suggest that learning communities foster vitality by serving as a boundary-spanning activity where faculty can merge various work interests, allowing them to engage in purposeful production and providing them with experiences that help generate feelings of energy, excitement, and engagement with their work.

Societal Adaptation To Decadal Climate Variability In The United States, Norman J. Rosenberg, Vikram M. Mehta, J Rolf Olsen, Hans Von Storch, Robert G. Varady, Michael J. Hayes, Donald A. Wilhite

United States Army Corps of Engineers, Omaha District

The search for evidence of decadal climatic variability (DCV) has a very long history. In the past decade, a research community has coalesced around a series of roughly biennial workshops that have emphasized description of past DCV events; their causes and their "teleconnections" responsible for droughts, floods, and warm and cold spells around the world; and recently, the predictability of DCV events. Researchers studying climate change put great emphasis on prospective impacts, but the DCV community has yet to do so. To begin rectifying this deficiency, a short but ambitious workshop was convened in Waikoloa, near Kona, Hawaii, from 26-28 …

Dynamics Of Wave-Current Boundary Layers Over Very Rough Boundaries, Marion Bandet-Chavanne

Link Foundation Ocean Engineering and Instrumentation Fellowship Reports

In this study, acoustic profiling techniques are used to resolve the two-dimensional spatial structures of the oscillating boundary layer in a phase-averaged sense over a wave orbital amplitude. The principal objective of this work is to examine the spatial variability of turbulent properties over irregular roughness. Field observations are used to investigate the interaction between bottom roughness, flow structure and turbulent properties within the near-bed flow. The overall focus of the research is to relate wave energy dissipation or friction factor estimates to physical roughness elements and understand the dynamics of such processes in the near-bed flow.

Semi-Autonomous Control Of Autonomous Underwater Vehicles, Stephen C. Martin

Link Foundation Ocean Engineering and Instrumentation Fellowship Reports

The goal of my graduate research is to address two engineering science problems whose solution will enable Autonomous Underwater Vehicles (AUVs) to routinely perform semi-autonomous missions presently considered impractical or infeasible. I am pursuing this research under the direction of Professor Whitcomb in the Dynamical Systems and Controls Laboratory at Johns Hopkins University, and in collaboration with the faculty of the Deep Submergence Laboratory of the Woods Hole Oceanographic Institution (WHOI).

In the last decade AUVs have begun to complement Human Occupied Vehicles (HOVs) and Remotely Operated Vehicles (ROVs) as effective platforms for oceanographic exploration. HOVs and ROVs are highly …

Salt And Ph Tunable Resist Patterns On Polyelectrolyte Multilayers, Christina Chan, Ilsoon Lee, Srivatsan Kidambi

Department of Chemical and Biomolecular Engineering: Faculty Publications

A method for selectively removing a resist material from the polycationic surface of a polyelectrolyte multilayer (PEM) ?lm, Without disturbing adhering interactions between the cationic ?lm surface and bound biomaterials such as cells, proteins, and nucleic acids. The resist material is one that that inhibits or prevents the further deposition of cells or other biomaterial; it thus masks the cationic surface from application of biomaterials. In one embodiment the resist material is a carboxy functional oxyalkylene oligomer. It is removed by exposing the ?lm containing the bound biomaterial and the bound resist material to a pH below 4.5, and/or to …

Cell Adhesion On Polyelectrolyte Multilayer Coated Polydimethylsiloxane Surfaces With Varying Topographies, Srivatsan Kidambi, Natasha Udpa, Stacey A. Schroeder, Robert Findlan, Ilsoon Lee, Christina Chan

Department of Chemical and Biomolecular Engineering: Faculty Publications

This article demonstrates that the micro-topography of the surface with respect to the pattern size and pitch influences cell adhesion and proliferation. Extensive research has shown the dependence of cell proliferation on substrate chemistry, but the influence of substrate topography on cell attachment has only recently been appreciated. To evaluate the effect of substrate physical properties (i.e., periodic microstructures) on cell attachment and morphology, we compared the response of several cell types (fibroblasts, HeLa, and primary hepatocytes) cultured on various polydimethylsiloxane (PDMS) patterns. PDMS has been used as an artificial construct to mimic biological structures. Although PDMS is widely used …

Department of Chemistry: Faculty Publications

The assessment of corrosion on the USS Arizona included the pioneering development of a minimum-impact cost-effective technique to determine the corrosion rate of steel-hulled shipwrecks in seawater. The technique, with potential application worldwide, is illustrated in this paper with the application to a World War II Japanese midget submarine submerged in deep waters off the Oahu, Hawaii, coast.

Integrative Lawyering: Navigating The Political Economy Of Urban Redevelopment Symposium: Race, Economic Justice, And Community Lawyering In The New Century, Sheila R. Foster

Faculty Scholarship

This shift from defending and reacting to creating and envisioning requires a more engaged organizational role for the lawyer. The lawyer is now expected to do more than translate the organization/community's grievance into discreet legal frameworks and discourse---e.g., a civil rights violation, a nuisance, participatory right, etc. The lawyer now intervenes in negotiations from which the organization or community has been excluded. This new role requires a shifting, flexible mix of skills and a more dynamic interaction with the organization and its varied functions-policy, community education, lobbying, and organizing. This new role is what we call "integrative lawyering," an emergent …
