Provincial government decentralization in Alberta: a case study of office relocation 1971-85
Creators: name: Foreman, William Earl
Publisher: name: University of Calgary
Year: 1988

description: Bibliography: p. 232-243.
description: This study deals with the effects of the Alberta Government's office decentralization policy, for the period 1971 to 1985. A review of the controls and policies used by other governments throughout the world who have tried to influence office location, provides the background to the case study of Alberta. The focus of the empirical study is upon the timing of government policy to decentralize its own staff, the offices affected, and the impact upon local employment and population growth. It will be shown that a policy of "scatter" has been employed m Alberta. Yet the concentration of government employment in the Alberta urban system has only been marginally affected, although some individual communities have gained substantially. Few efforts seem to have been made by the government to determine which types of offices are suitable for relocation, and which communities are appropriate as reception centres, so as to maximize the benefits from this policy initiative.

description: Numerical models of the wind-blown bubble of massive stars usually only account for the wind of a single star. However, since massive stars are usually formed in clusters, it would be more realistic to follow the evolution of a bubble created by several stars. We develope a two-dimensional (2D) model of the circumstellar bubble created by two massive stars, a 40 solar mass star and a 25 solar mass star, and follow its evolution. The stars are separated by approximately 16 pc and surrounded by a cold medium with a density of 20 particles per cubic cm. We use the MPI-AMRVAC hydrodynamics code to solve the conservation equations of hydrodynamics on a 2D cylindrical grid using time-dependent models for the wind parameters of the two stars. At the end of the stellar evolution (4.5 and 7.0 million years for the 40 and 25 solar mass stars, respectively), we simulate the supernova explosion of each star. Each star initially creates its own bubble. However, as the bubbles expand they merge, creating a combined, aspherical bubble. The combined bubble evolves over time, influenced by the stellar winds and supernova explosions. The evolution of a wind-blown bubble created by two stars deviates from that of the bubbles around single stars. In particular, once one of the stars has exploded, the bubble is too large for the wind of the remaining star to maintain and the outer shell starts to disintegrate. The lack of thermal pressure inside the bubble also changes the behavior of circumstellar features close to the remaining star. The supernovae are contained inside the bubble, which reflects part of the energy back into the circumstellar medium.

Observable consequences of quantum gravity: Can light fermions exist?

description: Any theory of quantum gravity must ultimately be connected to observations. This demand is difficult to be met due to the high energies at which we expect the quantum nature of gravity to become manifest. Here we study, how viable quantum gravity proposals can be restricted by investigating the interplay of gravitational and matter degrees of freedom. Specifically we demand that a valid quantum theory of gravity must allow for the existence of light (compared to the Planck scale) fermions, since we observe these in our universe. Within the effective theory framework, we can thus show that UV completions for gravity are restricted, regardless of the details of the microscopic theory. Specialising to asymptotically safe quantum gravity, we find indications that universes with light fermions are favoured within this UV completion for gravity.

The Effects of emersion and hypoxia on the hemolymph acid-base and oxygenation states of the horseshoe crab limulus polyphemus

description: Bibliography: p. 152-163.
description: The effects of both emersion and hypoxic exposure (followed by recovery) on hemolymph acid-base and oxygenation states of the horseshoe crab Limulus polyphemus were examined using both in vitro and in vivo measurements. In vivo studies involved sampling of hemolymph from animals exposed to emersion or hypoxia for 48h, followed by a 48h recovery period. To assess the effects of the repetitive sampling regime, h polyphemus exposed to normoxic seawater were also sampled for a 96h period. The in vitro determinations confirmed the presence of a reversed Bohr effect of comparable magnitude to that previously reported for h polyphemus hemolymph. In agreement with previous measurements made at similar hemolymph c1·, cooperativity of o2 binding to hemocyanin (n50 ) was low {1.4). Hemocyanin 02 affinity was, however, higher than previously measured at comparable levels of hemolymph Cl and pH (e.g. P50 = 5 torr at pH 7.6). This series also demonstrated that h polyphemus hemolymph lacks a Haldane effect. The in vivo studies demonstrated that repetitive sampling of hemolymph from animals in normoxic water had little effect on acid-base state. Mean hemolymph pH, Pco2, and Cco2 were stable throughout the sampling regime. Although ventilatory rate remained lower than has previously been reported, a hyperventilatory response was observed in response to sampling. This hyperventilation probably caused the elevation of hemolymph oxygen tensions, most marked during periods of intense sampling. The resultant increase in hemolymph 02 delivery to the tissues during the sampling regime was sufficient to fuel any increase in energy requirements caused by disturbance to the animal; the stable values for hemolymph lactate demonstrated that anaerobic metabolism was not utilized. In contrast to the stability of acid-base state of h polyphemus sampled in normoxic water, animals sampled during emersion demonstrated a marked respiratory acidosis. The elevation of hemolymph CO2 tensions and the decrease in 02 tensions to below 10 torr, both suggested that diffusion of gases across the emersed book gills was limited. The high affinity of h polyphemus hemocyanin for 02, however, allowed similar amounts of o2 to be delivered to the tissues as occurred in animals sampled in normoxic seawater. Although no compensation for acid-base disturbance occurred during emersion, potential hemolymph alkalosis during prolonged moderate hypoxic exposure was averted by elevation of hemolymph bicarbonate concentrations. This compensation prevented a decrease in hemocyanin 02 affinity from occurring via the reversed Bohr effect. Again, delivery of 02 to the tissues was not compromised.

description: It is shown that a simultaneous comparison of both elliptic and triangular flow from (2+1)-dimensional viscous fluid dynamics with recent measurements in Pb+Pb collisions at the Large Hadron Collider (LHC) favors a small specific shear viscosity (eta/s)_QGP approximately equal to 1/(4pi) for the quark-gluon plasma. Using this viscosity value, the relative magnitude of the elliptic and triangular flow is well described with Monte-Carlo Glauber (MC-Glauber) initial conditions while Monte-Carlo Kharzeev-Levin-Nardi (MC-KLN) initial conditions require twice as large viscosity to reproduce the elliptic flow and then underpredict triangular flow by about 30%.

description: We calculate the tunneling density-of-states (DOS) of a disorder-free two-dimensional interacting electron system with a massless-Dirac band Hamiltonian. The DOS exhibits two main features: i) linear growth at large energies with a slope that is suppressed by quasiparticle velocity enhancement, and ii) a rich structure of plasmaron peaks which appear at negative bias voltages in an n-doped sample and at positive bias voltages in a p-doped sample. We predict that the DOS at the Dirac point is non-zero even in the absence of disorder because of electron-electron interactions, and that it is then accurately proportional to the Fermi energy. The finite background DOS observed at the Dirac point of graphene sheets and topological insulator surfaces can therefore be an interaction effect rather than a disorder effect.

Estimation of the length of interactions in arena game semantics

description: We estimate the maximal length of interactions between strategies in HO/N game semantics, in the spirit of the work by Schwichtenberg and Beckmann for the length of reduction in simply typed lambdacalculus. Because of the operational content of game semantics, the bounds presented here also apply to head linear reduction on lambda-terms and to the execution of programs by abstract machines (PAM/KAM), including in presence of computational effects such as non-determinism or ground type references. The proof proceeds by extracting from the games model a combinatorial rewriting rule on trees of natural numbers, which can then be analyzed independently of game semantics or lambda-calculus.

Nonlinear pre-stress for cloaking from antiplane elastic waves
Creators: name: Parnell, William J.
Publisher: name: arXiv
Year: 2012
Subjects: subject: Classical Physics (physics.class-ph)
subject: FOS: Physical sciences

description: A theory is presented showing that cloaking of objects from antiplane elastic waves can be achieved by elastic pre-stress of a neo-Hookean nonlinear elastic material. This approach would appear to eliminate the requirement of metamaterials with inhomogeneous anisotropic shear moduli and density. Waves in the pre-stressed medium are bent around the cloaked region by inducing inhomogeneous stress fields via pre-stress. The equation governing antiplane waves in the pre-stressed medium is equivalent to the antiplane equation in an unstressed medium with inhomogeneous and anisotropic shear modulus and isotropic scalar mass density. Note however that these properties are induced naturally by the pre-stress. Since the magnitude of pre-stress can be altered at will, this enables objects of varying size and shape to be cloaked by placing them inside the fluid-filled deformed cavity region.

Evolution Of Androchromatism On Ischnura Females

sex-limited polymorphism

molecular phylogeny

description: Sex-related polichromatism has been observed as a determinant factor of insects’ sexual selection, especially in some groups of Odonata. In this group, the female androchromatic condition is frequently assumed to be useful to avoid unnecessary multiple mating events that can be harmful, since the androchromatic female is usually not recognized by the males. Species of Ischnura genus can be classified as monandrous or polyandrous accordingly to their mating system. By assuming that the androchromatism allows an almost monandric behavior, it is suggested that this polymorphism evolution has been favored in polyandric populations. We aimed to test this hypothesis by using phylogenetic, morphological and behavioral information. Morphological data concerning androchromatism was found for 27 species, while behavioral information were found for 17 (from a 65 total). Species for which both kinds of data were available (plus Telebasis salva and Coenagrion resolutum) were used in the phylogenetic reconstruction based on published molecular data. For that purpose, COII gene sequences were aligned by ClustalW2 and analyzed by MrBayes software, resulting in a consensus tree. As information about outgroups’ mate systems were lacking, 16 possibilities of characters evolution were tested in a sensitivity analysis. Since the usage of several statistical tests with the same data could inflate the probability of type I errors, we applied Bonferroni correction, considering p values as statistically significant only when lesser than 0.003. The number of character changes were tallied and compared by a Fisher’s exact test that returned 16 non-significant associations between variables, with p values ranging from 0.04 to 0.59. Recent studies have demonstrated the ancestral state for Ischnuran species as polyandric and polymorphic, the later being an old adaptation that does not influence organism’s fitness nowadays. It was also observed that colour alleles frequencies were highly similar in different populations, suggesting a non-random selection of this character, but morph frequencies must be under selective mechanisms unrelated to local environment. The reproductive isolation must play a role on the evolutionary pattern here exposed, as well as learned mate recognition and female behaviour. However, the lowest p value found here (0.04) reflects a reasonable evolutionary scenario where the plesiomorphic condition is heteromorphic females, and then polyandric system arose, suggesting that the later character evolved idependently, but may have leaded to changes in damselflies’ chromatomorphism. The test results indicate an independent evolution of polichromatism and mating systems in Ischnura.

description: The even weight period polynomial relations in the double shuffle Lie algebra $\mathfrak{ds}$ were discovered by Ihara, and completely classified by the second author by relating them to restricted even period polynomials associated to cusp forms on $\mathrm{SL}_2(\mathbb{Z})$. In an article published in the same year, Gangl, Kaneko and Zagier displayed certain linear combinations of odd-component double zeta values which are equal to scalar multiples of simple zeta values in even weight, and also related them to restricted even period polynomials. In this paper, we relate the two sets of relations, showing how they can be deduced from each other by duality.

description: In this paper, density functional theory calculations are used to explore the electronic and atomic reconstruction at interfaces between III-III/I-V oxides. In particular, at these interfaces, two dimensional electron gases (2DEGs) with twice the interfacial charge densities of the prototypical LaTiO3/SrTiO3 heterostructure are observed. Furthermore, a significant decrease in the band effective masses of the conduction electrons is shown, suggesting that possible enhancements in electron mobilities may be achievable. These findings represent a framework for chemically modulating 2DEGs, thereby providing a platform through which the underlying physics of electron confinement can be explored with implications for modern microelectronic devices.

description: Historically, coral reefs have always been important to the islands' visitors and residents. Coral reef resources provided food, medicines, and building materials for Native Hawaiians, as well as played an important role in social and cultural customs and traditions (Titcomb, 1972; Kirch, 1982). The traditional Native Hawaiian resource management system utilized in-depth knowledge of ocean resources to reduce waste and ensure long-term resource use. Over the last two centuries, however, economic, cultural, and political changes have altered and broken down traditional Native Hawaiian land and water use and management systems (Friedlander, 2004; Jokiel et al., 2011). Wide-scale degradation of nearshore resources likely began 100 to 200 years ago with the settlement of Western populations. Agriculture and livestock grazing became the primary land uses on Oʻahu, Maui, Molokaʻi, and Lanaʻi, which contributed to erosion and sedimentation on nearshore reefs (Gulko et al., 2002). Dredging and the filling in of nearshore reefs for residential, commercial, and military expansion led to continued reef degradation, especially in the last 100 years. Other changes include stream channelization and increased paving of land, which has reduced sediment erosion but increased runoff.

description: The controversy between creation and evolution sets date before Darwin and Wallace’s theory of the origin of species by means of natural selection. Evolutionists argue that life forms of our planet possess a single origin and they have changed through a long geological period of time. On the other side, Young Earth Creationists are contrary to the idea of a planet having more than a few thousands of years and of the common ancestry of the living beings. The United States of America have a high percentage of creationists in its population and the main authors that write about this theme are from there. In the XX century, these two lines of thought disputed in the US courts for space in the education boards. The American Young Earth Creationism influenced many Brazilian authors and some of them deal with issues concerning geology and paleontology. To defend that the Earth has few thousands of years, these creationists need to deal with the current methods of dating. One way to get an approximate idea of ​​the age of a stratigraphic layer is using relative dating, which depends on three guiding principles of modern geology: the original horizontality, lateral continuity and superposition of layers. They argue that some phenomena as fossilized trees found vertically through several stratigraphic layers and thrust faults preclude relative dating. Another frequent argument states that in the fossil record, species appear with no trace of transitional stages between them, and this should be a problem for evolution. The existence of transitional fossils is also contested. Transitional fossils would be species well adapted to their environment without the "need" of modification. Living fossils are presented as species that have not evolved, therefore, implying that no other species have done so. This study aimed to clarify these misunderstandings about evolution, based on recent geological and paleontological findings. We explain how the principles of actualism are still up to date. How the sudden appearance of species on the fossil record is expected, given the geologic dynamics. There is a variety of organisms that are, indeed, transitional fossils, and we give the example of the early evolution of the tetrapods. They appear in the predicted geological time and right stratigraphic column, with the right morphologic characters, belong to the predicted phylogenetic group and are associated to a predicted fauna. We show how the so called “living fossils” belong to lineages that indeed changed through time.

description: We present Chandra observations of 12 galaxies that contain supermassive black holes with dynamical mass measurements. Each galaxy was observed for 30 ksec and resulted in a total of 68 point source detections in the target galaxies including supermassive black hole sources, ultraluminous X-ray sources, and extragalactic X-ray binaries. Based on our fits of the X-ray spectra, we report fluxes, luminosities, Eddington ratios, and slope of the power-law spectrum. Normalized to the Eddington luminosity, the 2--10 keV band X-ray luminosities of the SMBH sources range from $10^{-8}$ to $10^{-6}$, and the power-law slopes are centered at $\sim2$ with a slight trend towards steeper (softer) slopes at smaller Eddington fractions, implying a change in the physical processes responsible for their emission at low accretion rates. We find 20 ULX candidates, of which six are likely ($>90%$ chance) to be true ULXs. The most promising ULX candidate has an isotropic luminosity in the 0.3--10 keV band of $1.0_{-0.3}^{+0.6} \times 10^{40}$ erg/s.

species distribution

description: Many important aspects of an organism’s life are closely related to its body size. As a consequence, size can be considered a driving factor on evolutionary history of animals, and some important ecological patterns have been proposed based on this measure. Recently, the Metabolic Theory of Ecology (MTE) suggests that higher metabolic rates are associated with small body sizes and this would determine species distribution patterns. Following the MTE, smaller animals should occupy smaller areas. A remarkably wide body size range can be seen on varanoid lizards. They also occupy a large variety of habitats and seem to have a very early origin, being good models for evolutionary ecology studies. We used the most recent Varanidae phylogeny to test if distribution areas reflect body mass variation. Because there is an ongoing debate about the taxonomic status of some species, we treated these as groups. We used the phylogenetic eigenvector regression method (PVR) both to detect and remove phylogenetic inertia in body and range size. The hypothesis was then tested by a Spearman correlation test using the PVR residuals. The PVR analysis indicated phylogenetic inertia on both variables (area: R²=0.68, p<0.001; body size: R²=0.44, p=0.005). However, the hypothesis test indicated that body size does not correlate with distributional area (ρ=-0.07, p=0.68). This result may be explained by the fact that monitor lizards are illegally traded as pets or source of valuable materials, possibly leading to invasions. Furthermore, the gigantism evolution in this group is reported to be independent of geographic isolation, but associated with habitat use. Therefore, body size might be limited by substrate availability. Moreover, differences in thermoregulatory skills among species may facilitate dispersion. The current findings add to a growing literature on MTE and general ecological patterns, elucidating the poor explanation provided by body size to variance in distribution range.

We extract two condition vectors from the real levels in an effort to control the details of the GAN's outputs. While the GANs perform well in approximating the first condition (map shape), they struggle to approximate the second condition (piece distribution). We hypothesize that this might be improved by trying out alternative architectures for both the Generator and Discriminator of the GANs.

description: We focus here on the analysis of the regularity or singularity of solutions $\Om_{0}$ to shape optimization problems among convex planar sets, namely: $$ J(\Om_{0})=\min\{J(\Om),\ \Om\ \textrm{convex},\ Ω\in\mathcal S_{ad}\}, $$ where $\mathcal S_{ad}$ is a set of 2-dimensional admissible shapes and $J:\mathcal{S}_{ad}\rightarrow\R$ is a shape functional. Our main goal is to obtain qualitative properties of these optimal shapes by using first and second order optimality conditions, including the infinite dimensional Lagrange multiplier due to the convexity constraint. We prove two types of results: i) under a suitable convexity property of the functional $J$, we prove that $Ω_0$ is a $W^{2,p}$-set, $p\in[1,\infty]$. This result applies, for instance, with $p=\infty$ when the shape functional can be written as $ J(Ω)=R(Ω)+P(Ω), $ where $R(\Om)=F(|\Om|,E_{f}(\Om),\la_{1}(\Om))$ involves the area $|Ω|$, the Dirichlet energy $E_f(Ω)$ or the first eigenvalue of the Laplace-Dirichlet operator $λ_1(Ω)$, and $P(Ω)$ is the perimeter of $\Om$, ii) under a suitable concavity assumption on the functional $J$, we prove that $Ω_{0}$ is a polygon. This result applies, for instance, when the functional is now written as $ J(\Om)=R(Ω)-P(Ω), $ with the same notations as above.

Ana Heylan: la primera burilista de ascendencia flamenca nacida en Andalucía
Creators: name: Pérez Galdeano, Ana María
Publisher: name: Miradas - Revista de Historia del Arte y la Cultura de las Américas y la Península Ibérica
Year: 2020

description: El objetivo principal de esta investigación ha sido desvelar la vida de Ana Heylan (Granada, 1615-1655) bajo la luz de las nuevas fuentes encontradas. Esta aportación documental permitirá, en primer lugar, abrir el debate respecto a discursos anteriores. Reflexión crítica que propiciará la ruptura de falsos mitos historiográficos establecidos sobre su persona. Esta grabadora granadina se convertirá en la primera mujer burilista andaluza que desarrollará su actividad profesional a partir de la tercera década del siglo XVII. Su ascendencia flamenca será una garantía para otorgarle una posición de prestigio dentro de su profesión. Era, por tanto, una apuesta de este trabajo tratar de mostrar las implicaciones que las circunstancias vitales de la artista tuvieron en el desarrollo de su persona y profesión; siendo estas condiciones circunstanciales el desencadenante de su definitiva inclinación por el arte del grabado en cobre.

description: We have used a relatively long, contiguous VHF observation of a bright cosmic radio source (Cygnus A) with the Very Large Array (VLA) to demonstrate the capability of this instrument to study the ionosphere. This interferometer, and others like it, can observe ionospheric total electron content (TEC) fluctuations on a much wider range of scales than is possible with many other instruments. We have shown that with a bright source, the VLA can measure differential TEC values between pairs of antennas (delta-TEC) with an precision of 0.0003 TECU. Here, we detail the data reduction and processing techniques used to achieve this level of precision. In addition, we demonstrate techniques for exploiting these high-precision delta-TEC measurements to compute the TEC gradient observed by the array as well as small-scale fluctuations within the TEC gradient surface. A companion paper details specialized spectral analysis techniques used to characterize the properties of wave-like fluctuations within this data.

description: We present the first entirely ground-based astrometric determination of the proper motion for the Fornax Local Group Dwarf Spheroidal satellite galaxy of the Milky Way, using CCD data acquired with the ESO 3.5 m NTT telescope at La Silla Observatory in Chile. Our unweighted mean from five Quasar fields in the background of Fornax, used as fiducial reference points, leads to $μ_α\cos δ=0.62 \pm 0.16$ $\masy$, and $μ_δ=-0.53 \pm 0.15$ $\masy$. A detailed comparison with all previous measurements of this quantity seems to imply that there is still no convincing convergence to a single value, perhaps indicating the existence of unnacounted systematic effects in (some of) these measurements. From all available proper motion and radial velocity measurements for Fornax, we compute Fornax's orbital parameters and their uncertainty using a realistic Galactic potential and a Monte Carlo simulation. Properties of the derived orbits are then compared to main star formation episodes in the history of Fornax. All published proper motion values imply that Fornax has recently (200-300 Myr ago) approached perigalacticon at a distance of $\sim$150 kpc. However, the derived period exhibits a large scatter, as does the apogalacticon. Our orbit, being the most energetic, implies a very large apogalactic distance of $\sim 950$ kpc. If this were the case, then Fornax would be a representative of an hypervelocity MW satellite in late infall.

Linear and Nonlinear Pulse Propagations in Lifetime-Broadened Atomic Media with Spontaneously Generated Coherence
Creators: name: Hang, Chao

Publisher: name: arXiv
Year: 2011
Subjects: subject: Optics (physics.optics)

description: The linear and nonlinear pulse propagations in lifetime-broadened three-state media with spontaneously generated coherence (SGC) are investigated theoretically. Three generic systems of V-, $Λ$-, and $Ξ$-type level configurations are considered and compared. It is shown that in linear propagation regime the SGC in the V-type system can result in a significant change of dispersion and absorption and may be used to completely eliminate the absorption and largely reduce the group velocity of a probe field. However, the SGC has no effect on the dispersion and absorption of the $Λ$- and $Ξ$-type systems. In nonlinear propagation regime, the SGC displays different influences on Kerr nonlinearity for different systems. Specifically, it can enhance the Kerr nonlinearity of the V-type system whereas weaken the Kerr nonlinearity of the $Λ$-type system. Using the SGC, stable optical solitons with ultraslow propagating velocity and very low pump power can be produced in the V-type system by exploiting only one laser field in the system.

description: Projected Hartree-Fock theory (PHF) has a long history in quantum chemistry. PHF is here understood as the variational determination of an N-electron broken symmetry Slater determinant that minimizes the energy of a projected state with the correct quantum numbers. The method was actively pursued for several decades but seems to have been abandoned. We here derive and implement a "variation after projection" PHF theory using techniques different from those previously employed in quantum chemistry. Our PHF methodology has modest mean-field computational cost, yields relatively simple expressions, can be applied to both collinear and non-collinear spin cases, and can be used in conjunction with deliberate symmetry breaking and restoration of other molecular symmetries like complex conjugation and point group. We present several benchmark applications to dissociation curves and singlet-triplet energy splittings, showing that the resulting PHF wavefunctions are of high quality multireference character. We also provide numerical evidence that in the thermodynamic limit, the energy in PHF is not lower than that of broken-symmetry HF, a simple consequence of the lack of size consistency and extensivity of PHF.

description: The near edge structure (XANES) in K-edge X-ray absorption spectroscopy (XAS) is a widely used tool for studying electronic and local structure in materials. The precise interpretation of these spectra with the help of calculations is hence of prime importance, especially for the study of correlated materials which have a complicated electronic structure per se. The single particle approach, for example, has generally limited itself to the dominant dipolar cross-section. It has long been known however that effects beyond this approach should be taken into account, both due to the inadequacy of such calculations when compared to experiment and the presence of shake-up many-body satellites in core-level photoemission spectra of correlated materials. This effect should manifest itself in XANES spectra and the question is firstly how to account for it theoretically and secondly how to verify it experimentally. By using state-of-the-art first principles electronic structure calculations and 1s photoemission measurements we demonstrate that shake-up many-body effects are present in K-edge XAS dipolar spectra of NiO, CoO and CuO at all energy scales. We show that shake-up effects can be included in K-edge XAS spectra in a simple way by convoluting the single-particle first-principles calculations including core-hole effects with the 1s photoemission spectra. We thus describe all features appearing in the XAS dipolar cross-section of NiO and CoO and obtain a dramatic improvement with respect to the single-particle calculation in CuO. These materials being prototype correlated magnetic oxides, our work points to the presence of shake-up effects in K-edge XANES of most correlated transition metal compounds and shows how to account for them, paving the way to a precise understanding of their electronic structure.
