Design and Analysis of Rotary Positive Displacement Mechanism for Oil-Less Compression
No full textAuthor(s): Holger Roser University of Technology Sydney, Sydney, NSW, Australia In this paper, a simple positive displacement mechanism is investigated, which comprises two counter-rotating meshing rotors within a casing. Although considered for various applications more than a century ago, the basic geometry of this mechanism has not been further explored or adapted to modern gas compressor technology

Investigation of the microscopic behavior of Mott insulators by means of the density functional theory and many-body methods
No full textThe objective of this work is twofold. First, we explore the performance of the density functional theory (DFT) when it is applied to solids with strong electronic correlations, such as transition metal compounds. Along this direction, particular effort is put into the refinement and development of parameterization techniques for deriving effective models on a basis of DFT calculations. Second, within the framework of the DFT, we address a number of questions related to the physics of Mott insulators, such as magnetic frustration and electron-phonon coupling (Cs2CuCl4 and Cs2CuBr4), high-temperature superconductivity (BSCCO) and doping of Mott insulators (TiOCl). In the frustrated antiferromagnets Cs2CuCl4 and Cs2CuBr4, we investigate the interplay between strong electronic correlations and magnetism on one hand and electron-lattice coupling on the other as well as the effect of this interplay on the microscopic model parameters. Another object of our investigations is the oxygen-doped cuprate superconductor BSCCO, where nano-scale electronic inhomogeneities have been observed in scanning tunneling spectroscopy experiments. By means of DFT and many-body calculations, we analyze the connection between the structural and electronic inhomogeneities and the superconducting properties of BSCCO. We use the DFT and molecular dynamic simulations to explain the microscopic origin of the persisting under doping Mott insulating state in the layered compound TiOCl

No full textThe dataset includes 15 subjects x 5 steady state conditions.
Connectivity data has been computed using FSLNETS with the following options:
- Timeseries from a set of 33 ROIs derived from functional data (Study-ROIs).
- Correlation as dependency measures.
- No bandpass filtering.
The connectivity_data.mat file includes:
netmatZ: connectivity data
Roi_names: names of the nodes
Roi_RSNs: classification of the 33 nodes into Motor, Visual and DMN networks.
Tval/Pval: results of the node-wise t-test comparison between rest and each of the active tasks.
The plot_connectivity.m file can be used to plot the average connectivity matrices for each task and the differences.
Connectivity results are grouped by RSN.

A Review of the Imaging Techniques for Measuring Kidney and Cyst Volume in Establishing Autosomal Dominant Polycystic Kidney Disease Progression
No full textBackground: Autosomal dominant polycystic kidney disease (ADPKD) is the commonest inherited renal disorder; it is defined by progressive renal cyst formation and subsequent renal enlargement that leads to end-stage renal disease. Until recently, only symptomatic treatments for ADPKD existed. However, therapies that address the underlying pathophysiology of ADPKD are now available and accurate identification of the rate of disease progression is essential. Summary: Published data on the different imaging modalities for measuring kidney and cyst volumes in ADPKD are reviewed. The advantages and drawbacks of the different techniques for calculating kidney volume from renal imaging are also examined, including the use of manual planimetry, stereology, and the ellipsoid equation, as well as the prospect of semi- and fully automatic techniques. The translation of these approaches into clinical practice and their role in informing treatment decisions is discussed. Key Messages: These new therapies require the accurate monitoring of disease progression, which along with diagnosis and prognosis, relies on the effective use of renal imaging techniques. There is growing support for the use of total kidney volume as a measure of cyst burden and as a prognostic predictor of renal function in ADPKD, showing promise as a marker of disease progression
Effect of disciplinary content of a simulation on open-ended problem-solving strategies
No full textThere is a long-standing debate about so-called generic vs. domain- or context-specific problem-solving skills and strategies. To investigate this issue, we developed a pair of structurally and functionally similar computer simulations and used them in an experimental study with undergraduate students from all fields of study. One, described to users as a teaching tool based on current entomology research, featured three species of ants whose tasks could change as a result of encounters with each other. The other, which we call a non-disciplinary simulation, featured three types of abstract moving shapes whose color could change after a collision. Users received no information about the latter, not even that it was a simulation. Both simulations, which students used in succession, allowed users to change the number and types of objects, and to move them freely on the screen. We told students that the problem was to describe and explain what occurred on the screen, and asked them to explain, while they were working with the simulation, what they observed, what they did and why. We conducted a first, quantitative analysis of various 'surface' indicators that can be related to patterns or strategies: computer-generated traces of significant events, including user interaction; users' operations (meaningful sequences of actions); basic characteristics and factual content of students' verbalizations. We found significant differences between the two simulations for a number of indicators, which are being used as guides in the next part of the study: an in-depth analysis of students' strategies
Full spin flipping in the presence of full Siberian Snake
No full textThis paper proposes a new design of spin flipper for high-energy accelerators to obtain full spin flip with the spin tune staying at half integer. The traditional technique of using a single rf spin rotator with a fixed spin rotation axis and an oscillating spin rotation, either an rf dipole or solenoid, as spin flipper to achieve full spin flip in the presence of a full Siberian snake has been demonstrated [B. B. Blinov et al., Phys. Rev. Lett. 81, 2906 (1998)PRLTAO0031-900710.1103/PhysRevLett.81.2906; B. B. Blinov et al., Phys. Rev. Lett. 88, 014801 (2001)PRLTAO0031-900710.1103/PhysRevLett.88.014801; V. S. Morozov et al., Phys. Rev. ST Accel. Beams 7, 024002 (2004)PRABFM1098-440210.1103/PhysRevSTAB.7.024002; R. A. Phelps, AIP Conf. Proc. 338, 361 (1994)APCPCS0094-243X; Ya. S. Derbenev et al., Part. Accel. 8, 115 (1978)PLACBD0031-2460]. However, this technique requires one to change the snake configuration to move the spin tune away from half integer which is not practical for an operational high-energy polarized proton collider such as RHIC where beam and polarization lifetime are sensitive to small changes. Based on the conceptual designs to use rf dipoles to achieve full spin flip with the spin tune at half integer [T. Roser, BNL Report No. BNL-52453, 1994; R. A. Phelps, BNL Report No. BNL-52453, 1994], this paper presents a compact design of a spin flipper for a high-energy accelerator. The theory of the new spin flipper technique and numerical simulations are also presented
