subject: Osteoarthritis

description: Muscle strengthening exercises consistently demonstrate improvements in the pain and function of adults with knee osteoarthritis, but individual response rates can vary greatly. Identifying individuals who are more likely to respond is important in developing more efficient rehabilitation programs for knee osteoarthritis. Therefore, the overall goal of this thesis was to identify responders to exercise with a conventional motion capture system and translate these findings into a clinically accessible wearable sensor system. It was found that a conventional motion capture system, in combination with patient-reported outcome measures (e.g., function) collected at the baseline of an exercise intervention can successfully predict responders to treatment with greater than 85% accuracy (chapter three). To translate these findings to the clinical setting, more accessible wearable sensors (e.g., accelerometers) were examined in the remaining chapters. Chapter four found that while a single sensor at the lower back could subgroup some gait patterns, it was not sensitive enough to separate other, more similar, gait patterns. Therefore, the reliability of using multiple wearable sensors was examined in chapter five. The lower back, thigh, shank, and foot were all found to be reliable sensor locations for gait analysis and therefore suitable in the final study as potential predictors of response. Finally, chapter six found that a unique combination of wearable sensor data and patient reported outcome measures could successfully identify responders to an exercise intervention with similar accuracy to the conventional motion capture system. Further, the best limited set of sensors included only the back and thigh. Therefore, these findings suggest the potential development of a simplified two sensor system that can provide clinicians with an efficient and relatively unobtrusive way to use to optimize treatment.

description: We formulate a quantitative theory of an electromotive force of spin origin, i.e., spin-motive force, by the equation-of-motion approach. In a ferromagnetic metal, electrons couple to the local magnetization via the exchange interaction. Electrons feel spin dependent forces due to this interaction, and then the spin-motive force and the anomalous Hall effect appears. We have revealed that the origin of these phenomena is a misalignment between the conduction electron spin and the local magnetization.

Resource Commitment and Cost Behavior Under Different Strategies

Subjects: subject: Education--Business
subject: Cost Behavior

description: I analyze asymmetric cost behavior from the perspective of resource commitment made to support strategic positions. Previous studies of asymmetric cost behavior consider how managers’ expectations about future demand in relation to costs of adjusting resources affect cost stickiness. My studies focus on how managers’ resource commitments made for strategic reasons affect cost behavior, and how cost stickiness as evidence of commitment to strategy is associated with firm performance. My first study investigates how resource commitment or resource flexibility reflected in cost stickiness is related to firm performance under different generic strategies. I interpret higher cost stickiness as evidence of commitment to a differentiation strategy and find that intangible value (measured by Tobin’s Q) associated with differentiation increases with cost stickiness. I also find that the persistence of return on assets (ROA) increases with cost stickiness for differentiators. My second study examines stickiness of SG&A costs as a consequence of resource commitments made to support a customer-focused strategy reflected in higher customer satisfaction. I find that customer satisfaction increases with both the intensity and stickiness of SG&A costs. I also document that the positive relation between intangible value and customer satisfaction increases with cost stickiness. My third study focuses on the airline industry in order to gain further insights about the roles of strategy and operations in determining cost behavior. In the airline industry, full service carriers (FSCs) employ clearly distinctive operating strategies from low cost carriers (LCCs). Resource complementarity is important to FSCs whose strategy depends on combinations of resources that enable high levels of service but resource flexibility is important to LCCs whose strategic goals are to minimize costs in both up and down markets. I use revenue passenger miles (RPMs) flown as the primary cost driver to separate the influence of volume changes from price changes on the empirical analysis. I find that operating costs, number of employees, and number of flights all exhibit stickiness for FSCs but not for LCCs.
Evaluation of ecosystem services of irrigated agriculture: a policy option for a sustainable water management

Publisher: name: Italian Review of Agricultural Economics

description: Irrigated agriculture can generate pressures on water bodies and, consequently, potential environmental costs; likewise, agricultural water use can provide several ecosystem services (ES). Both pressures and benefits must be included in the economic analysis of River Basin District Management Plans (RBDMPs), for the environmental cost accounting of agricultural water use. In the RBDMPs, the main reference for environmental benefits and costs accounting is the Program of Measures (PoM), as set by the Water Framework Directive (WFD). This paper aims to provide a review of the main ES of irrigated agro-ecosystem and to clarify how the implementation of the actions that support them can constitute an opportunity to internalize the environmental cost charged to agricultural sector.

description: This thesis evaluates American intelligence assessments of Japanese air and naval power during the interwar period. All issues from the assessment of personnel, tactics and technology, to strategy and industry are addressed together. American assessments of Japan’s poor strategic and industrial position remained highly accurate, while assessments of Japanese tactics and technology were flawed. Since the Americans planned to fight a prolonged war of attrition, strategic and industrial assessments proved far more critical than those which assessed low level issues. Their conclusion was that Japan could not win a war against the United States. Errors in the assessments of Japanese technology and tactics contributed to the shock and embarrassment of the early defeats in the Pacific War, but were not the main cause of those defeats. The underestimation of Japanese air power did more damage to the Americans than the middling assessments of Japanese naval power.

description: While a majority of the fast-growing U.S. Latino population is Roman Catholic, a significant and growing percentage is Protestant – some calculate that they now number 10 million in the U.S. Despite this significant growth, Latino Protestant churches remain understudied, particularly the music in worship services. Several Latino theologians criticize the music as being of foreign extraction, a form of neocolonialism in the church, not an autochthonous expression of worship. However, these claims do not align with music actually being used in these congregations. This
carefully documented study of 25 Spanish language Protestant churches in Oregon reveals that, while music used in worship at one time may have been created and
imposed by non-Latinos, this is no longer the case, and bi-musicality is the norm, reflecting the diaspora and agency of the Latino Protestant church.

description: This paper examines the detailed sub-milliarcsecond polarization properties of an individual SiO maser feature displaying a rotation in polarization electric vector position angle of approximately π/2 across the feature. Such rotations are a characteristic observational signature of circumstellar SiO masers detected toward a number of late-type, evolved stars. We employ a new calibration method for accurate circular VLBI polarimetry at millimeter wavelengths, to present the detailed Stokes {I,Q,U,V} properties for this feature. We analyze the fractional linear and circular polarization as a function of projected angular distance across the extent of the feature, and compare these measurements against several theoretical models proposed for sharp rotations of electric vector position angle in polarized SiO maser emission. We find that the rotation is most likely caused by the angle θbetween the line of sight and a projected magnetic field crossing the critical Van Vleck angle for maser propagation. The fractional linear polarization profile m_l(θ) is well-fit by standard models for polarized maser transport, but we find less agreement for the fractional circular polarization profile m_c(θ).

Subjects: Engineering--Electronics and Electrical

description: A variable-gain amplifier (VGA) is an important building block in wireless transceivers and it provides a constant receiver-output level for changing input power level due to varying inputs and interference. In this thesis, a VGA is designed and fabricated in an ST-Microelectronics 28-nm FDSOI CMOS technology for the next generation transceiver chips developed by PMC Sierra for application use in micro base stations, which operate over multiple radio bands, multiple carriers, and multi-antenna systems. The VGA is required to have wide bandwidth and high linearity to prevent desensitization of the receiver due to the signals from adjacent bands. Since the most challenging specification of the VGA is its linearity, different nonlinearity analysis methods along with different linearization techniques are discussed. The gain of the proposed VGA varies from 4.5dB to 11.5dB with a step of 1dB and the 3-dB bandwidth is 4.1GHz. The circuit achieved a maximum IIP3 of 26dBm for the high gain setting.

Rotary Inertial Navigation System with a Low-cost MEMS IMU and Its Integration with GNSS

description: Micro-electro-mechanical-systems (MEMS) inertial measurement unit (IMU) outputs are corrupted by significant sensor errors, such as noises, biases, scale factors, and installation errors. Consequently, the navigation errors of a low-cost inertial system with the MEMS IMU will accumulate quickly over time in stand-alone mode. Methods that can effectively mitigate the navigation errors without a need for external aiding, will be of great value for many applications. This research proposed a rotary inertial navigation system (INS) to mitigate navigation errors caused by MEMS inertial sensor errors when external aiding information is not available. A rotary INS is an inertial navigator in which the IMU is installed on a rotation platform. Application of proper rotation schemes can effectively cancel and reduce sensor errors. For example, the rotation of an IMU with a constant angular rate can modulate the constant inertial bias into periodic signals, and an integration of the modulated inertial data over a complete rotation cycle can eliminate the effect of the bias on the navigation solutions. Improvement of current inertial system’s observability in the absence of system maneuvers is also highly desired in applications. It is well known that the position and velocity from external aiding are extensively used to estimate the INS errors, and the weak maneuvers result in poor system observability and eventually degrade the navigation performance due to inaccurate estimation of INS errors. As the rotation changes the position of the IMU, the system observability is significantly improved in a rotary inertial system. Although the rotary INS has been applied to inertial system with high-end IMUs, it has not been investigated for low-cost MEMS IMUs. Given the fact that the MEMS IMU features significant sensor errors, as well as large and fast error variations, there are many issues and challenges that need to be addressed for effective navigation error mitigation and applications by rotary INS with MEMS IMUs. The conducted turntable tests and kinematic field tests indicate that with proper data processing, the horizontal position errors can be reduced by about 2~5 times in an inertial system with a rotating low-cost MEMS IMU, compared to those errors in a non-rotating system. Moreover, the observability of the roll and pitch errors, the accelerometer biases in the horizontal axes, and the gyro bias in the vertical direction can be significantly improved by IMU rotations.

description: We showcase in this paper the use of some tools from network theory to describe the strategy of football teams. Using passing data made available by FIFA during the 2010 World Cup, we construct for each team a weighted and directed network in which nodes correspond to players and arrows to passes. The resulting network or graph provides a direct visual inspection of a team's strategy, from which we can identify play pattern, determine hot-spots on the play and localize potential weaknesses. Using different centrality measures, we can also determine the relative importance of each player in the game, the `popularity' of a player, and the effect of removing players from the game.

description: Hydrogenated amorphous silicon thin film transistors have been used as switching elements in liquid crystal displays and large area matrix addressed sensor arrays. Later, these devices have also been used as analogue active elements in organic light emitting diode displays. However, this technology suffers from bias induced meta-stability. This issue introduces both threshold voltage and subthreshold slope shifts over time when gate bias is applied. Such instabilities jeopardize long term performance of circuits that rely on these components. Nevertheless, hydrogenated amorphous silicon thin film transistors present an exponential transfer characteristic when operating on subthreshold region and their typical power consumption is under 1 µW. This low power characteristic makes these devices ideally suited for low power electronic design. This work demonstrates, through transient analysis of a well-established simulation model for hydrogenated amorphous silicon, the viability of thin film transistors technology to perform both analogue and digital functions. Hence, these structures may be used in both application fields. To this end, two different sets of analyses have been conducted with hydrogenated amorphous silicon based thin film transistors. The first set considers a driving circuit for an active matrix of organic light emitting diodes, biased in a way to minimize the “memory effect” (increasing shift on threshold voltage) due to long term operation. The second set of analyses were conducted upon the implementation of complementary output universal gates, namely NOR/OR and XNOR/XOR elements.

We use the second-quantization formalism of Doi to bring the stochastic problem to a field-theoretic form. We investigate the reaction in the vicinity of the space dimension d=2 using a two-parameter expansion in $ε$ and $Δ$, where $ε$ is the deviation from the Kolmogorov scaling parameter and $Δ$ is the deviation from the space dimension d=2. We evaluate all the necessary quantities, including fixed points with their regions of stability, up to the second order of the perturbation theory.

In the regime of validity of continuum micromagnetism a domain wall is found to have no effect on the heat conductance. However, spin waves are found to be reflected by domain walls with widths of a few lattice spacings, which is associated with emergence of an additional spin wave bound state. The resulting domain wall heat conductance should be significant for thin films of Yttrium Iron Garnet with sharply defined magnetic domains.

description: The prospect for transitions and transformations in the energy sector to mitigate climate change raises concerns that actions should not shift the impacts from one impact category to another, or from one sustainability domain to another. Although the development of renewables mostly results in low environmental impacts, energy strategies are complex and may result in the shifting of impacts. Strategies to climate change mitigation could have potentially large effects on human health and ecosystems. Exposure to air pollution claimed the lives of about seven million people worldwide in 2010, largely from the combustion of solid fuels. The degradation of ecosystem services is a significant barrier to achieving millennium development goals. This thesis quantifies the biomass resources potential for Alberta; presents a user-friendly and sector-specific framework for sustainability assessment; unlocks the information and policy barriers to biomass integration in energy strategy; introduces new perspectives to improve understanding of the life cycle human health and ecotoxicological effects of energy strategies; provides insight regarding the guiding measures that are required to ensure sustainable bioenergy production; validates the utility of the Environmental Life Cycle Cost framework for economic sustainability assessment; and provides policyrelevant societal cost estimates to demonstrate the importance of accounting for human health and ecosystem externalities in energy planning. Alberta is endowed with a wealth of forest and agricultural biomass resources, estimated at 458 PJ of energy. Biomass has the potential to avoid 11-15% of GHG emissions and substitute 14-17% of final energy demand by 2030. The drivers for integrating bioenergy sources into Alberta’s energy strategy are economic diversification, technological innovation, and resource conservation policy objectives. Bioenergy pathways significantly improved both human health and ecosystem quality from coal fuel. Bioenergy alternatives have higher economic cost than the prevailing scenario of coal-fired generation system. Although coal fuel is the most cost effective way of electricity generation, its combustion results in the loss of 123.5 billion USD per year for Alberta due to societal life cycle cost. This research demonstrated that bioenergy can support the transformation of a fossil-based energy system to a more sustainable power production system; however, respiratory effects is a concern.

description: Air pollution has become one of the major challenges, with which humanity continues to struggle in modern times. The never-ending demand for energy has increased the production and consumption of different types of energy resources. A major part of the energy demand is met through the use of fossil fuels, which is one of the main sources of air pollution. In this thesis, a simple Life Cycle Assessment (LCA) model was created to represent the Greenhouse Gas (GHG) pollution of coal, natural gas and oil sands in Alberta. The model was complemented by developing a user-friendly and interactive visualization tool: The Greener Alberta, using recent software development techniques. The visualization tool enables the general public, especially younger generations, to learn about the industry procedures and to compare GHG emission rates of each energy resource. Finally, research surveys were conducted to verify the effectiveness of the Greener Alberta.

description: We present an analysis of the unusual optical light curve of the gamma-ray burst GRB 081029, a long-soft burst with a redshift of z = 3.8479. We combine X-ray and optical observations from the Swift X-Ray Telescope and the Swift UltraViolet/Optical Telescope with ground-based optical and infrared data obtained using the REM, ROTSE, and CTIO 1.3-m telescopes to construct a detailed data set extending from 86 s to approximately 100,000 s after the BAT trigger. Our data cover a wide energy range, from 10 keV to 0.77 eV (1.24 to 16,000 Angstrom). The X-ray afterglow shows a shallow initial decay followed by a rapid decay starting at about 18,000 s. The optical and infrared afterglow, however, shows an uncharacteristic rise at about 3000 s that does not correspond to any feature in the X-ray light curve. Our data are not consistent with synchrotron radiation from a jet interacting with an external medium, a two-component jet, or continuous energy injection from the central engine. We find that the optical light curves can be broadly explained by a collision between two ejecta shells within a two-component jet. A growing number of gamma-ray burst afterglows are consistent with complex jets, which suggests that some (or all) gamma-ray burst jets are complex and will require detailed modelling to fully understand them.

Comminution circuit design and simulation for the development of a novel high pressure grinding roll circuit
Creators: name: Rosario, Persio Pellegrini
Publisher: name: University of British Columbia
Year: 2010

description: The application of High Pressure Grinding Roll (HPGR) in comminution circuits is well established in processing cement, diamonds and iron ore. Recently, the application of HPGR has been extended to high-tonnage precious and base metals operations with hard ore. This is due to the HPGR: being more energy-efficient than grinding mills, not requiring steel grinding media, and providing higher throughputs than cone crushers. Although HPGR circuits are being used in high-tonnage precious and base metals, there is limited quantitative knowledge to indicate the true benefits or drawbacks of HPGR compared to Semi-autogenous mill (SAG). This lack of knowledge restricts the ability of designers to determine the optimal circuit. To address this lack of knowledge the research in this thesis: • Reviews the basics of the HPGR machine, its benefits and shortcomings. • Details the development of the SAG circuits and explains how the new generation of crushing circuits, with HPGR for tertiary crushing, are starting to replace SAG circuits in hard-rock mining. • Presents a structured methodology for comparison of the energy requirements for HPGR versus SAG complete circuits. The process is based on industrial best practices and advanced modelling tools, and is demonstrated through the evaluation of two hypothetical mining projects (based on real ore data). • Investigates the feasibility of a novel AG-Crusher-HPGR circuit using rock samples from a large copper-gold mining project. The approach was to develop and evaluate the circuit design for high-tonnage operations with mixed hardness ores containing clay. Previously, HPGR was considered only suitable for very hard ores and the technology was rejected for other cases. A unique pilot-plant test program was developed as a basis for experimental simulation. As a result the suitability of the circuit was demonstrated. The development of this novel circuit along with the findings of this research have the potential to improve future mining operations dealing with similar orebodies that, in fact, are major sources of base metals worldwide. The potential for significant savings in energy and steel media have been demonstrated. This may also lead to the selection of more sustainable circuits for a broader range of orebodies.

description: We develop an inhomogeneous mean-field theory for the extended Bose-Hubbard model with a quadratic, confining potential. In the absence of this potential, our mean-field theory yields the phase diagram of the homogeneous extended Bose-Hubbard model. This phase diagram shows a superfluid (SF) phase and lobes of Mott-insulator (MI), density-wave (DW), and supersolid (SS) phases in the plane of the chemical potential (μ) and on-site repulsion (U); we present phase diagrams for representative values of V, the repulsive energy for bosons on nearest-neighbor sites. We demonstrate that, when the confining potential is present, superfluid and density-wave order parameters are nonuniform; in particular, we obtain, for a few representative values of parameters, spherical shells of SF, MI, DW, and SS phases. We explore the implications of our study for experiments on cold-atom dipolar condensates in optical lattices in a confining potential

description: Oncolytic virus (OV) therapy for cancer is an emerging biotherapeutic strategy that employs replicating viruses to selectively infect and kill cancer cells. While promising, host innate immunity, namely type I IFN signaling, remains a barrier to OV therapy as it eliminates the virus before it spreads efficiently through the tumour. Sunitinib (Su), a receptor tyrosine kinase inhibitor, was recently shown to enhance OV infection by inhibiting IFN signaling in tumour cells. We therefore hypothesized that Su might enhance oncolytic rhabdovirus (ORV) infection in tumours. Indeed, Su treatment improved ORV productivity, tumour regression and overall survival in an IFN responsive tumour model. Su reduced the number and function of IFN producing myeloid cells such as cDCs and MΦ and thereby improved tumour infection with ORV. Collectively, our findings provide further support for the clinical evaluation of Su/ORV co-therapy in OV refractory tumors.

description: Modeling tumour control for prostate treatments can be challenging. Models used to predict tumour control are typically based on the well known linear-quadratic (LQ) model for cell survival. The LQ model accurately predicts cell killing for a given radiation dose in most cases, however in some cases the LQ model falls short and LQ model predictions differ from what has been observed experimentally. Cell survival following low radiation doses <1Gy and radiation induced bystander effects are two examples where the LQ model potentially falls short at modelling cell survival following an absorbed radiation dose. Using mathematical models that account for radiation induced bystander and low dose hypersensitivity effects, we look at how these effects potentially change predicted outcomes of tumour control when compared to standard LQ predictions. We start by investigating how the basic LQ model predicts tumour control under large geometric miss errors under intensity modulated radiation therapy (IMRT) and volume modulated arc therapy (VMAT) modalities. Next, we look at the geometric miss scenario again, but rather than compare two different delivery techniques we investigate how radiation induced bystander effects potentially change predicted tumour control under geometric miss cases. We then expand on this idea and study how radiation induced bystander effects potentially influence predicted outcome under heterogeneous dose distributions. Finally, we compare the relative biological effectiveness (RBE) of bystander effects with low dose hypersensitivity effects and spectral effects for out-of-field radiation doses. The majority of this work focused on how radiation induced bystander effect changed biological modeling of tumour control in external beam radiotherapy for prostate cancer. This work ultimately demonstrates that bystander effects can modify predicted outcomes of tumour control. We have shown that bystander effects potentially improve TCP under geometric miss and that bystander effects may relax the common planning constraint of aiming for dose homogeneity within a target volume.

description: In the present work we show a comprehensive comparison of our new stellar population synthesis MIUSCAT models with photometric data of globular clusters and early-type galaxies. The models compare remarkably well with the colours of Milky Way globular clusters in the optical range. Likewise, the colours of M31 globular clusters can also be explained by the models by assuming younger ages then their Galactic counterparts. When compared with quiescent galaxies we reproduce the colour evolution at intermediate redshift. On the other hand we find that the colour relations of nearby early-type galaxies are still a challenge for present-day stellar population synthesis models. We investigate a number of possible explanations and establish the importance of alpha-enhanced models to bring down the discrepancy with observations.

Contemporary ancestor? Variation in marine threespine stickleback (Gasterosteus aculeatus) and its implications for adaptive divergence

description: Standing genetic variation (SGV) can affect the incidence and pace of adaptation and parallel evolution. The role of SGV versus de novo mutation can be tested in ancestral-derived comparisons when the “contemporary ancestor” is extant. Assumptions about SGV in these contemporary ancestors require formal testing. The threespine stickleback is an icon of adaptive divergence, with multiple freshwater forms having evolved in parallel from a presumably panmictic, evolutionarily static marine population – in part from SGV at Ectodysplasin. Variation among marine stickleback would therefore have consequences for understanding adaptive divergence. I collected marine stickleback from eight locations between Alaska and California. Marine populations varied according to ecogeographic rules. Genotype-by-Sequencing of over 380 000 loci and 5700 SNPs revealed five genetic clusters, including one extending north from Washington to Alaska. Pairwise estimates of genetic differentiation (FST) ranged from 0.02 to 0.18. Tests of phenotypic divergence (PST-FST) for plate counts and body shape fell outside neutral evolutionary expectations, suggesting adaptive divergence may be maintaining this quantitative phenotypic variation among marine populations. Since SGV differed between populations, estimates of candidate loci exhibiting potential selection in response to freshwater colonisation varied depending on the marine population chosen as “ancestral”. It has been theorized that genome-wide heterozygosity improves fitness by buffering against asymmetry. If so, SGV could be maintained if it canalizes plate number. Although heterozygosity and asymmetry varied independently, SGV at Ectodysplasin acted as a genetic stressor that increased asymmetry. Critical thermal minima may have evolved from SGV. Contrary to expectations, marine and freshwater stickleback exhibited the same reaction norm for mitochondrial biogenesis, suggesting that biogenesis has not evolved but has retained an ancestrally adaptive phenotype. Collectively, these results reinforce that SGV is a complex and important factor in the evolution of “contemporary ancestors”, and that failure to take these complexities into account can lead to spurious interpretations of adaptation in derived populations.
Spinons and helimagnons in the frustrated Heisenberg chain

description: We investigate the dynamical spin structure factor S(q,w) for the Heisenberg chain with ferromagnetic nearest (J1<0) and antiferromagnetic next-nearest (J2>0) neighbor exchange using bosonization and a time-dependent density-matrix renormalization group algorithm. For |J1|<< J2 and low energies we analytically find and numerically confirm two spinon branches with different velocities and different spectral weights. Following the evolution of S(q,w) with decreasing J1/J2 we find that helimagnons develop at high energies just before entering the ferromagnetic phase. Furthermore, we show that a recent interpretation of neutron scattering data for LiCuVO4 in terms of two weakly coupled antiferromagnetic chains (|J_1|<< J2) is not viable. We demonstrate that the data are instead fully consistent with a dominant ferromagnetic coupling, J1/J2 ~ -2.

description: Among the members of the series R2PdSi3 (R= Rare-earths), the magnetic behavior of the Nd compound is interesting in some respects. This compound is considered to order ferromagnetically (below 16 K), unlike other members of this series which order antiferromagnetically. In addition, magnetic ordering temperature (To) is significantly enhanced with respect to de Gennes scaled value. In order to understand the magnetism of this compound better, we have investigated the magnetic behavior in detail (under external pressure as well) and also of its solid solutions based on substitutions at Nd and at Si sites, viz., on the series, Nd(2-x)(Y,La)(x)PdSi(3-y)Ge(y) (x, y= 0.2, 0.4, 0.8, and 1.2) by bulk measurements. The results overall establish that Nd2PdSi3 orders ferromagnetically below 16 K, but antiferromagnetic component seems to set in at very low temperatures. Notably, there is a significant suppression of To for Y and Ge substitutions, compared to La substitution, for a given magnitude of unit-cell volume change, however qualitatively correlating with the separation between the layers of Nd and Pd-Si(Ge). On the basis of this observation, we conclude that 4f(Nd) hybridization plays a major role on the magnetism of the former solid solutions. To our knowledge, this work serves as a rare demonstration of 4f-hybridization effects on the magnetism of a Nd-based intermetallic compound.

description: We present both phenomenological and more physical photoionization models of the Chandra HETG spectra of the Seyfert-1 AGN NGC 4051. We detect 40 absorption and emission lines, encompassing highly ionized charge states from O, Ne, Mg, Si, S and the Fe L-shell and K-shell. Two independent photoionization packages, XSTAR and Cloudy, were both used to self-consistently model the continuum and line spectra. These fits detected three absorbing regions in this system with densities ranging from 10^{10} to 10^{11} cm^{-3}. In particular, our XSTAR models require three components that have ionization parameters of log ξ= 4.5, 3.3, & 1.0, and are located within the BLR at 70, 300, and 13,000 R_g, respectively, assuming a constant wind density. Larger radii are inferred for density profiles which decline with radius. The Cloudy models give a similar set of parameters with ionization parameters of log ξ= 5.0, 3.6, & 2.2 located at 40, 200, and 3,300 R_g. We demonstrate that these regions are out-flowing from the system, and carry a small fraction of material out of the system relative to the implied mass accretion rate. The data suggest that magnetic fields may be an important driving mechanism.
