Quantum criticality of Ce1−x_{1-x}Lax_{x}Ru2_{2}Si2_{2} : the magnetically ordered phase

We report specific heat and neutron scattering experiments performed on the system Ce$_{1-x}$La$_{x}$Ru$_{2}$Si$_{2}$ on the magnetic side of its quantum critical phase diagram. The Kondo temperature does not vanish at the quantum phase transition and elastic scattering indicates a gradual localisation of the magnetism when $x$ increases in the ordered phase.Comment: To be published in the proceedings of QCNP0

Yucca Mountain Saturated Zone Carbon-14

This Scientific Investigation Plan (SIP) provides an overview of the work described in “Yucca Mountain Saturated Zone Carbon-14”, a proposal funded by the U.S. Department of Energy’s (DOE) Office of Repository Development under the UCCSN/YMP Co-op in support of the Science and Technology Initiatives. The objective of this work is to provide improved estimates of the time required for ground water to travel from the site of the proposed high-level radioactive waste repository at Yucca Mountain, Nevada, to the accessible environment

Strategic Alignment: Analysis of Perspectives

This paper focuses on the strategic alignment model and how it has been operationalized to enable assessment of an organization’s business and technology strategies into one of twelve defined alignment perspectives using a web-based model. Analysis of data from a multi-year study suggests that certain industries favor specific alignment perspectives. Further analysis of longitudinal data appears to yield distinct patterns of strategy development among industries

Groundwater Flow and Thermal Modeling to Support a Preferred Conceptual Model for the Large Hydraulic Gradient North of Yucca Mountain

This task will create a two-dimensional, saturated zone, vertical cross-section model of groundwater flow and thermal transport through the large hydraulic gradient (LHG). This model is referenced herein as the thermal model. The scope of this study is limited to presenting a postulated hydrogeologic configuration of the LHG. The conceptualization will include the use of postulated hydrogeologic structures and material properties. The thermal model will be spatially limited to the area immediately upgradient and downgradient of the LHG and will not reproduce the many hydrogeologic features of the existing regional and site-scale models. The thermal model will be orientated north to south, approximately along a saturated zone streamline. The results of the thermal modeling will be compared to temperature data reported for site wells by the U.S. Geological Survey (USGS) and in peer-reviewed journals. Most, if not all, of this reported data is non- qualified. This task will not qualify the reported data and the reported data will be used only as a basis of comparison for the model simulations

The advantages of virtual microscopy for teaching histology

The use of high resolution scanned digital images, which can be stored in virtual archives on local or distant servers, has resulted in novel approaches in e-learning (both in the classroom and also for distance learning) [1]. This is leading to major changes in the way practical histology and histopathology classes are taught. After an initial investment in the scanning stage microscope and associated software and servers, the financial and administrative advantages allow enormous economic savings in the long-term with regard to equipment, technical staff and laboratory facilities. There is no longer a need for individual student microscopes, for technical staff for microscope maintenance or repair or worries about the loss of valuable specimens. There is no longer a need for individual slide sets or to prepare new slides. It is a win-win situation that medical school administrators, teachers and students appreciate and which has led to widespread adoption of virtual microscopy systems in the life sciences. Students today, are all highly computer competent, and greatly appreciate the advantages of the virtual microscopy systems. If the virtual histology archive is web-based (and not just on a local server) then students can access the laboratory material at any time, day or night, prepare assignments and prepare for examinations. The virtual microscopy systems are ideal for computerized examinations of histology and histopathology material. The lecture will deal with the various hardware options (light microscope scanning stage systems), commercial software for e-learning, problems of copyright, and also the establishment of national repositories for virtual image archives. A description will be presented of the experience of introducing a virtual microscopy system in the Faculty of Medicine in Haifa, where some 450 of the most outstanding histology slides have been scanned and placed on the virtual microscopy archive and made available for students. In addition to e-learning, establishment of a virtual microscopy system allows telepathology, storage of histopathology archives especially in hospital environments including tissue array images, automated diagnostics of specific diseases, and quantitative image analysis. It is likely that in the coming decade all medical and nursing teaching units will move to virtual microscopy. This is an inevitable process and it is important to understand the advantages and disadvantages before taking decisions on the specific system to be adopted

Artificial scaling laws of the dynamical magnetic susceptibility in heavy-fermion systems

We report here how artificial, thus erroneous, scaling laws of the dynamical magnetic susceptibility can be obtained when data are not treated carefully. We consider the example of the heavy-fermion system Ce$_{0.925}$La$_{0.075}$Ru$_{2}$Si$_{2}$ and we explain how different kinds of artificial scaling laws in $E/T^\beta$ can be plotted in a low temperature regime where the dynamical susceptibility is nearly temperature independent.Comment: 4 pages, 4 figure

Electroweak Higgs as a pseudo-Goldstone boson of broken scale invariance

We point out that it is possible to associate the electroweak Higgs boson with the pseudo-Goldstone boson of broken scale invariance, thus resolving the hierarchy problem in a technically natural way. We illustrate this idea with two specific gauge models. Besides being consistent with all currently available experimental data, both models maintain the predictive power of the standard model, since the first model has only one additional parameter beyond the standard model, and the second has the same number of free parameters as the standard model.Comment: 11 pages, discussion added, the version to appear in Phys. Lett.

Quantum Necking in Stressed Metallic Nanowires

When a macroscopic metallic wire is subject to tensile stress, it necks down smoothly as it elongates. We show that nanowires with radii comparable to the Fermi wavelength display remarkably different behavior. Using concepts from fluid dynamics, a PDE for nanowire shape evolution is derived from a semiclassical energy functional that includes electron-shell effects. A rich dynamics involving movement and interaction of kinks connecting locally stable radii is found, and a new class of universal equilibrium shapes is predicted.Comment: 4 pages, 3 postscript figures. New result on universal equilibrium shape

Chemical Analyses in Support of Yucca Mountain Studies

The objective of this task “Chemical Analyses in Support of Yucca Mountain Studies” is to provide the Department of Energy (DOE) with data and reports from comprehensive chemical analyses of waters sampled from the wells of the Nye County Early Warning Drilling Program (NCEWDP), the Inyo County’s Drilling Program, and the Nye county Tracer Test. In addition, this task will be used to provide other laboratory support needs as they arise within the Yucca Mountain Project. This support is provided by the Harry Reid Center for Environmental Studies (HRC) at University of Nevada, Las Vegas (UNLV), which is part of the University and Community College System of Nevada (UCCSN)
