description: In 1934 B. Berggren first discovered the surprising result that every Pythagorean triplet is the pre product of the triplet (3, 4, 5) presented as a column by a product of three matrices, that every triplet is obtained in this manner exactly once and in primitive form. In this paper we show a similar result for integer triangles with an angle of 60 degrees (also known as Eisensteinian triplets). We show that any such triangle is obtained by pre-multiplication (7,8,5) or (13,15,7) by a product of five matrices. The result might have applications in enumerating points with rational distance from the origin on the hexagonal lattice.

description: Heat management becomes more and more critical, especially in miniaturized modern devices, so the exploration of highly thermally conductive materials with electrical insulation and favorable mechanical properties is of great importance. Here, we report that high-quality monolayer boron nitride (BN) has a thermal conductivity (\k{appa}) of 751 W/mK at room temperature. Though smaller than that of graphene, this value is larger than that of cubic boron nitride (cBN) and only second to those of diamond and lately discovered cubic boron arsenide (BAs). Monolayer BN has the second largest \k{appa} per unit weight among all semiconductors and insulators, just behind diamond, if density is considered. The \k{appa} of atomically thin BN decreases with increased thickness. Our large-scale molecular dynamic simulations using Green-Kubo formalism accurately reproduce this trend, and the density functional theory (DFT) calculations reveal the main scattering mechanism. The thermal expansion coefficients (TECs) of monolayer to trilayer BN at 300-400 K are also experimentally measured, and the results are comparable to atomistic ab initio DFT calculations in a wider range of temperatures. Thanks to its wide bandgap, high thermal conductivity, outstanding strength, good flexibility, and excellent thermal and chemical stability, atomically thin BN is a strong candidate for heat dissipation applications, especially in the next generation of flexible electronic devices.

In the Y quadrant of the zone, where there are no complications from ghost bands caused by the superlattice, we find a gap function consistent within error bars to the form cos(k_x)-cos(k_y) expected for a d-wave order parameter. Similar results are found in the X quadrant with the photon polarization chosen to enhance main band emission over that due to ghost bands.

description: Cyclic systems of dichotomous random variables have played a prominent role in contextuality research, describing such experimental paradigms as the Klyachko-Can-Binicoglu-Shumovky, Einstein-Podolsky-Rosen-Bell, and Leggett-Garg ones in physics, as well as conjoint binary choices in human decision making. Here, we understand contextuality within the framework of the Contextuality-by-Default (CbD) theory, based on the notion of probabilistic couplings satisfying certain constraints. CbD allows us to drop the commonly made assumption that systems of random variables are consistently connected. Consistently connected systems constitute a special case in which CbD essentially reduces to the conventional understanding of contextuality. We present a theoretical analysis of the degree of contextuality in cyclic systems (if they are contextual) and the degree of noncontextuality in them (if they are not). By contrast, all previously proposed measures of contextuality are confined to consistently connected systems, and most of them cannot be extended to measures of noncontextuality. Our measures of (non)contextuality are defined by the L_{1}-distance between a point representing a cyclic system and the surface of the polytope representing all possible noncontextual cyclic systems with the same single-variable marginals. We completely characterize this polytope, as well as the polytope of all possible probabilistic couplings for cyclic systems with given single-variable marginals.[...]

description: Losses of site nitrogen have been reported in British Columbia following prescribed burning and mechanical blading treatments used for site preparation in reforestation. While these treatments often lead initially to improved tree seedling establishment and survival, amelioration of nitrogen losses may be necessary to sustain long-term site productivity. Inoculated Trifolium hybridum L. (alsike clover) was seeded at O, 10, 20, and 30 kg/ha with Pinus contorta Doug, ex Loud (lodgepole pine) seedlings to determine 1) the effects of site preparation on infection and effectiveness of the clover-Rhizobium symbiosis and clover cover, and 2) the effects of the clover-Rhizobium symbiosis on survival, early growth, and foliar nitrogen concentration of the lodgepole pine seedlings and on soil nitrogen content and availability. The nitrogen-fixing symbiosis successfully established in all treatments, and site preparation (broadcast burn, windrow burn, and mechanical forest floor removal) had no significant effect on clover percent cover. After four growing seasons, the symbiosis had no effect on survival or height and diameter incremental growth of the seedlings. However, both needle mass and foliar nitrogen concentrations were significantly greater in clover-seeded plots compared to controls. There were significant increases in forest floor total and rnineralizable nitrogen as rate of seeding increased, although a similar effect was not detected for the mineral soil layer.

description: I conducted a descriptive analysis of the effectiveness of how mothers communicate with their children during a compliance task and whether the mothers’ observed effectiveness related to their self-reported, self-efficacy scores. Participants consisted of 37 mother-child dyads in which the children were preschool-aged and were diagnosed with Autism Spectrum Disorder (ASD). I observed and transduced the mothers’ antecedents and consequences, as well as the children’s responses, using prerecorded videos that contained a 2-min compliance task (cleaning up after a free-play session). The procedure consisted of identifying the mothers’ antecedents and the consequences for the child’s behaviors and determining their form. Mothers’ forms were classified as being either vocal, combined, or nonvocal. The children of the study were classified by their level of verbal development using the Verbal Behavior Developmental Assessment-Revised (VBDA-R). The two levels of verbal development utilized for this study were the foundational level and the listener level. Results of the study indicated: 1) mothers of children at both the foundational and listener levels of verbal development were more likely to use a combined approach for antecedents and a vocal approach for consequences, 2) mothers did not significantly differ in their form when communicating based on their child’s level of verbal development, 3) children at both levels of verbal development emitted almost equally low levels of correct responding, 4) more antecedents emitted by mothers across both levels of verbal development were correlated with higher incorrect responding by their children, 5) for children at the foundational level of verbal development, higher incorrect responses were correlated with more combined interactions (antecedents and consequences summed), and for children at the listener level of verbal development, higher incorrect responses were correlated with more vocal interactions (antecedents and consequences summed), 6) mothers of children at either level of verbal development did not significantly differ in their use of contingent consequences, 7) contingent disapprovals were positively correlated with incorrect responses for children at the listener level of verbal development, 8) contingent corrections were positively correlated with incorrect responding for children at both levels of verbal development, 9) mothers’ reported self-efficacy was not correlated to their child’s level of verbal development, nor was it correlated with their child’s correct or incorrect responding.

description: Shifting from a phase of rapid growth in urbanization into a moderate-paced stage, China has faced many complicated problems during the urban regeneration period. To deal with complex urban problems, urban regeneration often requires integrated and coordinated strategies involving a wide range of stakeholders. Hence, a deeper understanding of the stakeholders is an essential step towards sustainable urban regeneration. Besides, many NGOs have emerged to try to provide a smooth communication platform for all parties. Therefore, this thesis would like to explore the interaction between various stakeholders and the role NGO plays in the regeneration process of old residential compounds in Shanghai through case studies. It will include a case study of Hongxian Residential Compound Regeneration Project and rely on interviews and observations to help understand stakeholders in a more in-depth way. The method of stakeholder analysis will be employed to identify, prioritize, analyze the stakeholders and their roles. The result shows that the government occupies an absolute dominant position in the power structure, while NGO has also been empowered to take a lead. Local residents and other participants have few say during the regeneration process. Meanwhile, NGO would serve as both of a key mediator, and an organizer and provider of community cultural services in the different stages. Therefore, the author calls for the policy support for NGO’s involvement, the empowerment of different stakeholders and the encouragement of public participations in the future.

description: Public transport as a means of transport is an essential part of moving travelers from place to place. Considering the aggregate mode of travel, public transport is regarded as a more environmental friendly and sustainable travel mode compared to single occupancy vehicles travel. I am interested to discover the exact factors on how built environment, individual characteristics and characteristics in travel could change mode choice preference in New York Metropolitan Area. The 2010-2011 NYMTC Regional Household Travel Survey and 2010 ACS 5-year estimate data will be used to establish multinomial logit models to interpret the effects.  From model results, both high population density and job density help to encourage more public transport trips. The effects of population density and job density only vary by trip purposes. Other socioeconomic and trip-based variables also play significant role on mode choice decisions.

Children's literature in mathematics education

description: Math storybook reading can be a beneficial activity in the home numeracy environment that facilitates children’s exploration and understanding of numbers. Parents play an important role in guiding and supporting their children’s math development through their joint engagement in the story. Exploring how parents and their children interact during home activities such as math storybook reading is crucial given strong associations between the home numeracy environment and later academic success. The primary goal of this study was to investigate how parents supported their children’s early numeracy development as they responded to children’s number mistakes and engaged their children in conversation about the number concepts present in the story. Observations of parent-child interactions (n = 47) while reading a math storybook and interviews with parents were intended to uncover how parents can use storybooks as a means of involving their children in math learning and guiding their understanding of numbers. The present study expands on the extant math storybook literature by examining the role of parental beliefs and home practices in shaping parents’ and children’s behaviors during math storybook reading. Results indicated that parents’ beliefs about the importance of early math learning and their role in helping their children learn math were associated with a lower frequency of children’s simple math mistakes, a greater degree of support parents provided in response to those mistakes, and a greater amount of simple math concepts parents discussed with their children while reading. Furthermore, children exposed to a greater frequency of home counting activities completed more of the math tasks in the storybook. Finally, three main factors that appeared to drive parents’ selection and use of math storybooks were children’s interest, attention spans, and math abilities. These findings support the use of math storybooks as a potentially beneficial activity that can elicit positive parent-child interactions around number concepts and demonstrate that parents are intentional in how they use storybooks to guide their children’s math development. The results are discussed in relation to home support for early numerical development and contextualized within the math storybook literature.

description: The role of frequency is very important in electromagnetics since it may significantly change how a material interacts with an incident wave if the frequency spectrum varies. Here, we demonstrate a new kind of microwave window that has the unique property of controlling transmission and reflection based not only on the frequency of an incoming wave but also on the waveform or pulse width. This surface can preferentially pass or reject different kinds of signals, such as short pulses or continuous waves, even if they occur at the same frequency. Such a structure can be used, for example, to allow long communication signals to pass through, while rejecting short radar pulses in the same frequency band. It is related to the classic frequency selective surface, but adds the new dimension of waveform selectivity, which is only possible by introducing nonlinear electronics into the surface. Thus, our study is expected to provide new solutions to both fundamental and applied electromagnetic issues ranging from traditional antenna design and wireless communications to emerging areas such as cloaking, perfect lenses, and wavefront shaping.

How Population Size and Density Affect the Spread of COVID-19 A Quantitative Study of the United States at the County Level

description: The scholarly debate about the influence of population density on COVID-19 spread points to a question: whether it is a larger population density, or a larger size of the population, that actually accelerate the spread of the virus . To figure out an answer in the US context, proper considerations should be taken to deal with three highly-influential determinants of the shape of a COVID-19 curve: the timeline of policy interventions, the metro and non-metro division, and the phase of pandemic. To safely unmask the effect of population size and density at county level, I introduce a group of “seasonal surges” and “COVID-19 policy reaction” variables, which measure to what extent a pandemic surge happened in a season, and whether the surge was followed by effective policy intervention within the season. Besides, a group of interaction variables based on the division of metro and non-metro counties are added to address some socio-cultural differences. To generally interpret the results, population density positively correlates with COVID-19 spread, while population negatively correlates with COVID-19 spread. However, in the early phase of pandemic, density had negative impact only in metro counties, although in later phases the effect of density no longer differed between metro and non-metro counties. The negative impact of population on COVID-19 cases are most observable in non-metro counties, while its coefficient for metro counties was evidently smaller.
Positive solutions for quasilinear elliptic inequalities and systems with nonlocal terms

description: We investigate the existence and nonexistence of positive solutions for the quasilinear elliptic inequality $L_\mathcal{A} u= -{\rm div}[\mathcal{A}(x, u, \nabla u)]\geq (I_α\ast u^p)u^q$ in $Ω$, where $Ω\subset \mathbb{R}^N, N\geq 1,$ is an open set. Here $I_α$ stands for the Riesz potential of order $α\in (0, N)$, $p>0$ and $q\in \mathbb{R}$. For a large class of operators $L_\mathcal{A}$ (which includes the $m$-Laplace and the $m$-mean curvature operator) we obtain optimal ranges of exponents $p,q$ and $α$ for which positive solutions exist. Our methods are then extended to quasilinear elliptic systems of inequalities.
The millennium King Arthur : the commodification of the Arthurian legend in the 20th century
Creators: name: Pfanner, David E
Publisher: name: The Australian National University
Year: 2008

description: The prophesy that King Arthur will return has come true. This legendary icon of Western civilization lives again in the popular culture novels of contemporary and futuristic literature. While the king’s personality has changed little since Malory, the monarch is now often found as a superhero in new world settings: he has become a Celtic space traveller among the stars, a modern politician fighting corruption, a WWII fighter pilot, a battler of aliens, and even returns as a teenage boy. Wherever he goes, King Arthur encounters a variety of personalised evil opponents from his medieval past as well as futuristic aliens and monsters. The authors and publishers of Arthurian popular culture have commodified the Arthurian legend, turning the king into an Americanised romantic superhero who overcomes his opponents but mostly fails to meet the reality of modern socio-economic challenges. The king has a limited understanding of what constitutes evil in the modern world so that despite his worthy character as a role model, his grasp of action required to overcome injustice constitutes a major shortcoming. The reasons for this are sought among the authors and publishers that produced these novels, and among the literary critics and the sociological literature focusing on the linkages between literature and society.

description: Given the path of a point particle, one can relate its acceleration and, in general, its kinematics to the curvature scalars of its trajectory. Using this, a general Ansatz is made for the Yang Mills connection corresponding to a non-Abelian point source. The Yang Mills field equations are then solved outside the position of the point source under physically reasonable constraints such as finite total energy flux and finite total color charge. The solutions contain the Trautman solution; moreover two of them are exact whereas one of them is found using a series expansion in 1/R, where R is the retarded distance. These solutions are new and, in their most general form, are not gauge equivalent to the original Trautman solution.

Conditions are found under which singular sets of prescribed dimension cannot occur. Various degrees of smoothness are proven for the sonic limit, high-dimensional flow, and flow having nonzero vorticity. The gradient flow of solutions is estimated. Implications for other quasilinear field theories are suggested.

description: Traffic simulations are made more realistic by giving individual drivers intentions, i.e. an idea of where they want to go. One possible implementation of this idea is to give each driver an exact pre-computed path, that is, a sequence of roads this driver wants to follow. This paper shows, in a realistic road network, how repeated simulations can be used so that drivers can explore different paths, and how macroscopic quantities such as locations of jams or network throughput change as a result of this.
Integration of Satellites into 5G Eco-systems

description: The Fifth-Generation of Mobile Communications (5G) is intended to satisfy the growing needs of users which can be summarised in the ability to access good quality services anywhere and at any time. Those needs can be supported by the integration of satellites in 5G systems due to the unique characteristics of satellites in terms of higher coverage, reliability, and availability. In particular, Low Earth Orbit (LEO) satellite constellations offer an appealing approach for supporting and complementing Fifth-Generation of Mobile Communications (5G) New Radio (NR) communications have the advantages of low propagation delay and low energy consumption which makes them the best candidates for direct access 5G Non-Terrestrial Networks (NTN). However, the major problem of LEO satellites is their higher speed relative to the terrestrial mobile terminals, which causes mobile users to hand over between satellites which has a negative impact on users’ Quality of Service (QoS) if occurs in high frequency. Moreover, 5G communication technologies are designed to support a wide spectrum of applications, including Artificial Intelligence, Virtual Reality, and the Internet of Things (IoT). Thus, differentiating User Equipments (UEs) with different and varying Traffic-Profiles (TP) has become necessary due to each application’s unique performance requirements. Complicating matters further, LEO satellites operate with limited onboard resources, including energy and channel resources. Thus a satellite handover management strategy is needed to tackle all the above challenges. To tackle these challenges, we propose innovative LEO Satellite Handover management strategies. These strategies mark a groundbreaking advancement by accounting for application diversity per user and addressing the limited energy resources of LEO satellites. Notably, these strategies successfully minimize the number of HOs, achieving a zero blocking rate while effectively balancing the load among satellites. On the other hand, to minimize blind exploitation of new systems, new technologies should be verified and enhanced before being implemented to reduce the required cost and time. In this context, we implemented an open-source System Level Simulator (SLS) built on the foundation of the Network Simulator 3 (NS-3). This tool enables the simulation of 5G Satellite-Terrestrial Integrated Networks (STIN) and surpasses existing solutions by supporting Non-Terrestrial Networks (NTN) handover decisions, dynamic BandWidth Part (BWP) selection, and Component Carrier (CC) configurations tailored to different traffic profiles.

description: This thesis presents a comprehensive study of the epigraphic record for athletes from the Late Hellenistic and Imperial periods. It argues that if we examine the athletic source material in full, we will see that there is great variety in the styles of athletic self-representation, and that often different aspects of athletic identity are emphasized in different kinds of honorific evidence. Chapter 2 examines inscribed athletic epigrams: it aims to shed light on the many facets of athletic identity that they construct, and explores the many artful techniques they use in order to project the various personas of their honorees more effectively. Chapter 3 moves on to examine prose athletic inscriptions, and more specifically a new kind of inscription, involving extensive listing of victories and citizenships, that emerges during the Imperial period, and demonstrates how this body of evidence gives us a taste of the experience of being Greek under Rome. Chapter 4 examines how textual portrayals of athletics varied significantly across different regions of the empire, and argues that athletic victory in Macedonia did not have the same strong impact on the civic life of the polis as in other regions of the Greek speaking world, for example Ionia. The thesis also aims to illustrate, more broadly, the way in which epigraphic portrayals of athletes are intertwined with important contemporary debates about elite self-representation, political culture, and issues of the negotiation of Hellenic identity in the Roman Empire. Throughout, inscriptions are examined not just as sources of information, but for their rhetoric, as texts that project powerful views of the world in their own right, in the process shedding new light on the many different roles played by athletes in their interactions with their cities and other communities during the Late Hellenistic and Imperial periods.
How Power and Powerlessness Corrupt

description: This dissertation examines how and when, both powerfulness and powerlessness, can each lead to corrupt behavior. The first half of this dissertation (Chapters 2 to 5) focuses on the link between power and corrupt behavior. Building on previous work that expansive posture induces a state of power, four studies tested whether expansive posture incidentally imposed by our environment lead to increases in dishonest behavior. Chapters 2 to 4 present three experiments, which found that powerful individuals were more likely to steal money, cheat on a test, and commit traffic violations in a driving simulation. Results suggested that participants' self-reported sense of power mediated the link between postural expansiveness and dishonesty. In an observational field study, Chapter 5 revealed that automobiles with more expansive driver's seats were more likely to be illegally parked on New York City streets. The second part of the dissertation examines if powerlessness can lead to corrupt behavior. Chapters 6 to 10 present a new theoretical model that comprehensively integrates theories on power and regulatory focus. This model reveals that both powerfulness and powerlessness can each lead to corrupt behavior, but through different routes. Three experiments in Chapters 7 to 9 found that prevention-powerlessness and promotion-powerfulness produce more corrupt behavior than promotion-powerlessness and prevention-powerfulness, as evident in individuals' tendency to exploit others, aggression, and dishonest behavior. I also found evidence for the affective manifestations that accompany these effects. Indeed, a meta-analysis on the data suggests that prevention-powerlessness and promotion-powerfulness significantly produced more corrupt behavior than prevention-powerfulness and promotion-powerlessness. These findings have important theoretical implications for power and regulatory focus, and explicate how powerlessness can lead to taking action and even corruption.
Plane-chain coupling in YBa$_{2}$Cu$_{3}$O$_{7}$ : impurity effect on the critical temperature

description: We have studied the effect of impurities on $T_{c}$ for a model of YBCO involving pairing both in the CuO$_{2}$ planes and in the CuO chains. In this model pairing in the planes is due to phonons, while Coulomb repulsion induces in the chains an order parameter with opposite sign. Due to the anticrossing produced by hybridization between planes and chains, the order parameter changes sign on a single sheet of the Fermi surface resulting in nodes in the gap. We find that $T_{c}$ is much less sensitive to impurities than in standard d-wave models. One reason is that impurities produce essentially plane-plane and chain-chain scattering, which does not affect the critical temperature. $T_{c } $ is reduced by plane-chain scattering, which is smaller by a factor of order hybridization coupling over Fermi energy. In the specific case which we have studied in details and which reduces to the two-band model, we have found a further reduction of the sensitivity of $T_{c}$ to impurities with a behaviour which can vary continuously from s-wave like to d-wave like depending on the parameters. We expect a similar reduction to occur in the general case.

How Planning Process Impacts Bus Rapid Transit Outcomes:  A Comparison of Experiences in Delhi and Ahmedabad, India

description: The ongoing debate within the Bus Rapid Transit (BRT) community over the relative importance of 'appropriate' design standards, the 'right' institutional setup and 'political will' to the success of projects obscures the larger importance of the planning process.  Political leadership, institutions and design are important conditions that must be considered in the context of one another, but they are also conditions that will change and be influenced by the planning process. Drawing on case studies of the Janmarg BRT in Ahmedabad, and the Delhi BRT in India, I demonstrate the indirect and direct role of the planning process in influencing the outcome of BRT projects.
      My dissertation argues that planners too often treat the planning process as a one-dimensional sequence of steps in which design, institutions and leadership provide an unchanging framework in which planning proceeds.  Planners however, can assert more influence over outcomes by re-framing the process as a three dimensional activity that considers not just the content and sequencing of the steps, but also requires decisions concerning approach (i.e. strategy and tactics) and timing (i.e. both moment of action and duration).  This broader three-dimensional understanding of the planning process can be used to reshape design, institutions and leadership.  A well-designed planning process has the potential to overcome institutional and design weaknesses and build political support leading to more viable and sustainable BRT systems.
Impact of thermal effects on the evolution of eccentricity and inclination of low-mass planets

description: Using linear perturbation theory, we evaluate the time-dependent force exerted on an eccentric and inclined low-mass planet embedded in a gaseous protoplanetary disc with finite thermal diffusivity $χ$. We assume the eccentricity and inclination to be small compared to the size of the thermal lobes $λ\sim(χ/Ω)^{1/2}$, itself generally much smaller than the scalelength of pressure $H$. When the planet is non-luminous, we find that its eccentricity and inclination are vigorously damped by the disc, over a timescale shorter by a factor $H/λ$ than the damping timescale in adiabatic discs. On the contrary, when the luminosity-to-mass ratio of the planet exceeds a threshold that depends on the disc's properties, its eccentricity and inclination undergo an exponential growth. In the limit of a large luminosity, the growth rate of the eccentricity is 2.5~times larger than that of the inclination, in agreement with previous numerical work. Depending on their luminosity, planetary embryos therefore exhibit much more diverse behaviours than the mild damping of eccentricity and inclination considered hitherto.

description: Technology has long been viewed an important tool in education and instructional software offers unique affordances that when designed well can help improve teaching and learning. However, for software to effectively impact education, teachers must be prepared to effectively incorporate it into the classroom. This is a task that involves many factors, three of which explored in this study include the abilities to integrate, find, and evaluate quality of educational software.
      With the increasing support for the use of educational software with young children, it is imperative to understand the unique challenges early childhood teachers face and how teacher education programs are preparing them to meet the demands of an evolving 21st century education system. Contrary to their colleagues who teach older students, extensive research on this population and topic is largely absent.
      Given that little research has been done to evaluate how prepared pre-service teachers are to enter the early childhood classroom and integrate educational software, the main goals of this study were to offer preliminary insight on their experiences using and preparing to use educational software with young children; how they approach evaluating quality of educational software; and beliefs on how well their teacher education programs have prepared them.
      Results from this study have important implications for the design of teacher education programs and in-service professional development on the integration of educational software at the early childhood grade levels. This paper provides initial evidence that pre-service early childhood teachers may be under-prepared to enter the classroom ready to effectively integrate educational software and demonstrates a clear need for more research on how teacher education programs prepare their students to integrate, find, and evaluate quality of educational software in the classroom setting. Furthermore, results also offer school administrators insight on how prepared first year teachers are meet classroom expectations. For educational technology to significantly impact teaching and learning, targeted in-service professional development opportunities and enhanced teacher education may be necessary, even for the generations of teachers who grew up during the technological explosion.

description: Line-intensity mapping, being an imperfect observation of the line-intensity field in a cosmological volume, will be subject to various anisotropies introduced in observation. Existing literature in the context of CO and [C II] line-intensity mapping often predicts only the real-space, spherically averaged line-intensity power spectrum, with some works considering anisotropies while examining projection of interloper emission. We explicitly consider a simplified picture of redshift-space distortions and instrumental effects due to limited resolution, and how these distort an isotropic line-intensity signal in real space and introduce strong apparent anisotropies. The results suggest that while signal loss due to limited instrumental resolution is unavoidable, measuring the quadrupole power spectrum in addition to the monopole would still break parameter degeneracies present in monopole-only constraints, even without a measurement of the full anisotropic power spectrum.
