description: Three-phase suspensions, of liquid that suspends dispersed solid particles and gas bubbles, are common in both natural and industrial settings. Their rheology is poorly constrained, particularly for high total suspended fractions ($\gtrsim 0.5$). We use a dam-break consistometer to characterize the rheology of suspensions of (Newtonian) corn syrup, plastic particles, and CO$_2$ bubbles. The study is motivated by a desire to understand the rheology of magma and lava. Our experiments are scaled to the volcanic system: they are conducted in the non-Brownian, non-inertial regime; bubble capillary number is varied across unity; and bubble and particle fractions are $0\leqϕ_{gas}\leq0.82$ and $0\leqϕ_{solid}\leq0.37$ respectively. We measure flow-front velocity and invert for a Herschel--Bulkley rheology model as a function of $ϕ_{gas}$, $ϕ_{solid}$, and the capillary number. We find a stronger increase in relative viscosity with increasing $ϕ_{gas}$ in the low to intermediate capillary number regime than predicted by existing theory, and find both shear-thinning and shear-thickening effects, depending on the capillary number. We apply our model to the existing community code for lava flow emplacement, PyFLOWGO, and predict increased viscosity and decreased velocity compared with current rheological models, suggesting existing models may not adequately account for the role of bubbles in stiffening lavas.

description: Bloch and Okounkov introduced an $n$-point correlation function on the fermionic Fock space and found a closed formula in terms of theta functions. This function affords several distinguished interpretations and in particular can be formulated as correlation functions on irreducible $\hat{gl}_\infty$-modules of level one. These correlation functions have been generalized for irreducible integrable modules of $\hat{gl}_\infty$ and its classical Lie subalgebras of positive levels by the authors. In this paper we extend further these results and compute the correlation functions as well as the $q$-dimensions for modules of $\hat{gl}_\infty$ and its classical subalgebras at negative levels.

description: We study a four-dimensional effective theory of the five-dimensional (5D) gauged supergravity with a universal hypermultiplet and perturbative superpotential terms at the orbifold fixed points. Among eight independent isometries of the scalar manifold, we focus on three directions for gauging by the graviphoton. The class of models we consider includes the 5D heterotic M-theory and the supersymmetric Randall-Sundrum model as special limits of the gauging parameters. We analyze the vacuum structure of such models, especially the nature of moduli stabilization, from the viewpoint of the effective theory. We also discuss the uplifting of supersymmetric anti-de Sitter vacua.

description: A novel Key Quality Indicator for video delivery applications, XLR (piXel Loss Rate), is defined, characterized, and evaluated. The proposed indicator is an objective measure that captures the effects of transmission errors in the received video, has a good correlation with subjective Mean Opinion Scores, and provides comparable results with state-of-the-art Full-Reference metrics. Moreover, XLR can be estimated using only a lightweight analysis on the compressed bitstream, thus allowing a No-Reference operational method. Therefore, XLR can be used for measuring the quality of experience without latency at any network location. Thus, it is a relevant tool for network planning, specially in new high-demanding scenarios. The experiments carried out show the outstanding performance of its linear-dimension score and the reliability of the bitstream-based estimation.

The problem of local government reform in rural Bangladesh : the failure of Swanirvar Gram Sarkar
Creators: name: Huque, Ahmed Shafiqul
Publisher: name: University of British Columbia
Year: 2010

description: Since World War II, there have been several attempts to reform local government in rural Bangladesh. They were aimed, among other things, at increasing food production, improving living conditions in the villages, encouraging participation by the villagers in the management of local affairs, and bringing the villages closer to the central government. Most of these objectives have never been attained despite the initiation of various schemes to reform local government. The latest attempt, the Swanirvar Gram Sarkar ("self-reliant village government") scheme launched in 1980 by the government of Ziaur Rahman, is a case in point. This dissertation analyzes the motives which brought Swanirvar Gram Sarkar into existence, and the factors that led to its termination in 1982. In order to understand the generally chronic failure of local government reforms in developing countries like Bangladesh, it is necessary to consider the existing local government systems in their particular historical contexts, the political circumstances under which reforms are introduced, and the socio-economic conditions prevailing in the localities. A review of the historical evolution of local government in Bangladesh indicates that all of its rulers, both foreign and indigenous, have been reluctant to actually decentralize power. They have designed local institutions in such a way as to ensure control by the centre. Moreover, at the intermediate (district and union) level, rural elites, who have been in control of the existing local government institutions, try to impede the decentralization of power to the village level. They view new local institutions such as Swanirvar Gram Sarkars as threats, and put up obstacles to prevent their operation. There is yet another explanation for the failure in local government reforms. Even if the government decides to decentralize power, the villages may not be prepared to receive it, since they have not achieved uniform levels of political mobilization. This dissertation makes use of historical evidence, the findings of previous research, government documents, and field study observation. It provides an in-depth investigation of the politics of three villages representing different regions of Bangladesh. In addition to the historical and national political factors affecting local government reform, conditions in these villages are examined for evidence explaining why Swanirvar Gram Sarkar, with few exceptions, was so unsuccessful.

description: Modern microgrids are networked systems comprising physical and cyber components for networking, computation, and monitoring. These cyber components make microgrids more reliable but increase the system complexity. Therefore, risk assessment methods are an imperative technology for cyber-physical systems to ensure safe and secure operations. The authors propose a reliability approach that utilizes the failure modes of power and cyber network key components to perform the risk analysis in microgrids. In this work, the authors have used the Failure Mode and Effect Analysis (FMEA) approach for risk assessment of microgrid systems and determine the influence of various failure modes on their performance. FMEA is one of the most effective methods to assess the risk involving the cyber components. It is the method of examining components, modules, and subsystems to determine failure modes in a system and their causes and consequences. A novel approach is proposed to calculate risk priority numbers based on factors like severity, occurrence, and detection. A risk matrix is calculated from the proposed FMEA worksheet, which acts as a graphical representation for evaluating components risk based on risk priority number or criticality metrics.

description: The majority of non-merging stellar mass black holes are discovered by observing high energy emission from accretion processes. Here we pursue the large, but still mostly unstudied population of non-interacting black holes and neutron stars by searching for the tidally-induced ellipsoidal variability of their stellar companions. We start from a sample of about 200,000 rotational variables, semi-regular variables, and eclipsing binary stars from the All-Sky Automated Survey for Supernovae (ASAS-SN). We use a $χ^2$ ratio test followed by visual inspection to identify 369 candidates for ellipsoidal variability. We also discuss how to combine the amplitude of the variability with mass and radius estimates for observed stars to calculate a minimum companion mass, identifying the most promising candidates for high mass companions.

We also analyze the data of the previous numerical investigations of lattice Electroweak theory. We have found that moving along the line of constant physics when the lattice spacing $a$ is decreased, one should leave the physical Higgs phase of the theory at a certain value of $a$. Our estimate of the minimal value of the lattice spacing is $a_c = [430\pm 40 {\rm Gev}]^{-1}$.

description: We studied the dynamical response of a nanomechanical resonator to biomolecular (e.g. DNA) adsorptions on a resonator's surface by using a theoretical model, which considers the Hamiltonian H such that the potential energy consists of elastic bending energy of a resonator and the potential energy for biomolecular interactions. It was shown that the resonant frequency shift of a resonator due to biomolecular adsorption depends on not only the mass of adsorbed biomolecules but also the biomolecular interactions. Specifically, for dsDNA adsorption on a resonator's surface, the resonant frequency shift is also dependent on the ionic strength of a solvent, implying the role of molecular interactions on the dynamic behavior of a resonator. This indicates that nanomechanical resonators may enable one to quantify the biomolecular mass, implying the enumeration of biomolecules, as well as gain insight into intermolecular interactions between adsorbed biomolecules on the surface.

description: The characteristics of the stellar populations in the Galactic Bulge inform and constrain the Milky Way's formation and evolution. The metal-poor population is particularly important in light of cosmological simulations, which predict that some of the oldest stars in the Galaxy now reside in its center. The metal-poor bulge appears to consist of multiple stellar populations that require dynamical analyses to disentangle. In this work, we undertake a detailed chemodynamical study of the metal-poor stars in the inner Galaxy. Using R$\sim$ 20,000 VLT/GIRAFFE spectra of 319 metal-poor (-2.55 dex$\leq$[Fe/H]$\leq$0.83 dex, with $\overline{\rm{[Fe/H]}}$=-0.84 dex) stars, we perform stellar parameter analysis and report 12 elemental abundances (C, Na, Mg, Al, Si, Ca, Sc, Ti, Cr, Mn, Zn, Ba, and Ce) with precisions of $\approx$0.10 dex. Based on kinematic and spatial properties, we categorise the stars into four groups, associated with the following Galactic structures: the inner bulge, the outer bulge, the halo, and the disk. We find evidence that the inner and outer bulge population is more chemically complex (i.e., higher chemical dimensionality and less correlated abundances) than the halo population. This result suggests that the older bulge population was enriched by a larger diversity of nucleosynthetic events. We also find one inner bulge star with a [Ca/Mg] ratio consistent with theoretical pair-instability supernova yields and two stars that have chemistry consistent with globular cluster stars.

description: We present observations of rotational lines of H2S, SO and CS performed in comet C/1995 O1 (Hale-Bopp) in March 1997 with the Plateau de Bure interferometer (IRAM). The observations provide informations on the spatial and velocity distributions of these molecules. They can be used to constrain their photodissociation rate and their origin. We use a radiative transfer code which allows us to compute synthetic line profiles and interferometric maps, to be compared to the observations. Both single-dish spectra and interferometric spectral maps show a day/night asymmetry in the outgassing. From the analysis of the spectral maps, including the astrometry, we show that SO and CS present in addition a jet-like structure that may be the gaseous counterpart of the dust high-latitude jet observed in optical images. A CS rotating jet is also observed. Using the astrometry provided by continuum radio maps obtained in parallel, we conclude that there is no need to invoke of nongravitational forces acting on this comet, and provide an updated orbit. The radial extension of H2S is found to be consistent with direct release from the nucleus. SO displays an extended radial distribution. Assuming that SO2 is the parent of SO, the photodissociation rate of SO is measured to be 1.5 E-4 s-1 at 1 AU from the Sun. This is lower than most laboratory-based estimates and may suggest that SO is not solely produced by SO2 photolysis. From the observations of J(2-1) and J(5-4) CS lines, we deduce a CS photodissociation rate of 1 to 5 E-5 s-1. The photodissociation rate of CS2, the likely parent of CS, cannot be constrained due to insufficient resolution, but our data are consistent with published values. These observations illustrate the cometary science that will be performed with the future ALMA interferometer.

description: A shallow potential well in a near-perfect quantum wire will bind a single-electron and behave like a quantum dot, giving rise to spin-dependent resonances of propagating electrons due to Coulomb repulsion and Pauli blocking. It is shown how this may be used to generate full entanglement between static and flying spin-qubits near resonance in a two-electron system via singlet or triplet spin-filtering. In a quantum wire with many electrons, the same pairwise scattering may be used to explain conductance, thermopower and shot-noise anomalies, provided the temperature/energy scale is sufficiently high for Kondo-like many-body effects to be negligible.

In the limit of small molecular diffusivity the problem can be described by a spatially discretized system, and this allows for an efficient numerical simulation. If the initial field profile is supported in a region of size l < lc one has quenching, i.e., flame extinction, where lc is a characteristic length-scale depending on the system parameters (reacting time, molecular diffusivity and velocity field). We derive an expression for lc in terms of these parameters and relate our results to those obtained by other authors for different flow settings.

A reference to this taxon listed in Fédière et al. (1989) from the Ivory Coast has not been found and is not included in Table 4. As this species is absent from the catalogs of Schenkling (1921), Krajčík (1998, 1999) and Schoolmeesters (2021), we believe it is in error.As further evidence, Janson did publish two papers in 1907 (Janson 1907a,b) but this species was not included in either one. Therefore, this record most likely refers to Acrothyrea scintillans (De Lisle, 1947) which is known from the Ivory Coast (Beinhundner 2017; Moretto & Rojkoff 2021).

description: We present a catalog of 167 newly discovered, irregular variables spanning a $\sim$7 deg${^2}$ area that encompasses the G 305 star-forming complex, one of the most luminous giant H II regions in the Galaxy. We aim to unveil and characterize the young stellar object (YSO) population of the region by analyzing the $K_{\rm s}$-band variability and $JHK_{\rm s}$ infrared colors from the {\it VISTA Variables in the Vía Láctea} (VVV) survey. Additionally, SDSS-IV APOGEE-2 infrared spectra of selected objects are analyzed. The sample show relatively high amplitudes ($0.6611$ mag and duration longer than a few days, typically at least a year, known as {\it Eruptive Variables}. About 60% are likely to be Class II/Flat/I objects. This is also confirmed by the spectral index $α$ when available. From the analysis of APOGEE-2 near-infrared spectra of sources in the region, another 122 stars are classified as YSOs, and displays some infrared variability. The measured effective temperature $T_{\rm eff}$ peak is around 4000K and they are slightly super-solar in metal abundance. The modal radial velocity is approximately $-$41 km/s. Combining available catalogs of YSOs in the region with our data, we investigate the spatial distributions of 700 YSOs. They are clearly concentrated within the central cavity formed by the massive clusters Danks 1 and 2. The calculated surface density for the entire catalog is 0.025 YSOs/pc$^{-2}$, while the central cavity contains 10 times more objects per area (0.238 YSOs/pc$^{-2}$).

The Imprint of Cosmic Reionization on Galaxy Clustering

description: We consider the effect of reionization on the clustering properties of galaxy samples at intermediate redshifts (z~0.3-5.5). Current models for the reionization of intergalactic hydrogen predict that overdense regions will be reionized early, thus delaying the build up of stellar mass in the progenitors of massive lower-redshift galaxies. As a result, the stellar populations observed in intermediate redshift galaxies are somewhat younger and hence brighter in overdense regions of the Universe. Galaxy surveys would therefore be sensitive to galaxies with a somewhat lower dark matter mass in overdense regions. The corresponding increase in the observed number density of galaxies can be parameterized as a galaxy bias due to reionization. We model this process using merger trees combined with a stellar synthesis code. Our model demonstrates that reionization has a significant effect on the clustering properties of galaxy samples that are selected based on their star-formation properties. The bias correction in Lyman-break galaxies (including those in proposed baryonic oscillation surveys at z<1) is at the level of 10-20% for a halo mass of 10^12 solar masses, leading to corrections factors of 1.5-2 in the halo mass inferred from measurements of clustering length. The reionization of helium could also lead to a sharp increase in the amplitude of the galaxy correlation function at z~3. We find that the reionization bias is approximately independent of scale and halo mass. However since the traditional galaxy bias is mass dependent, the reionization bias becomes relatively more important for lower mass systems. The correction to the bias due to reionization is very small in surveys of luminous red galaxies at z<1.

description: The microwave radiometer aboard the Juno spacecraft provided a measurement of the water abundance found to range between 1 and 5.1 times the protosolar abundance of oxygen in the near-equatorial region of Jupiter. Here, we aim to combine this up-to-date oxygen determination, which is likely to be more representative of the bulk abundance than the Galileo probe subsolar value, with the other known measurements of elemental abundances in Jupiter, to derive the formation conditions and initial composition of the building blocks agglomerated by the growing planet, and that determine the heavy element composition of its envelope. We investigate several cases of icy solids formation in the protosolar nebula, from the condensation of pure ices to the crystallization of mixtures of pure condensates and clathrates in various proportions. Each of these cases correspond to a distinct solid composition whose amount is adjusted in the envelope of Jupiter to match the O abundance measured by Juno. The volatile enrichments can be matched by a wide range of planetesimal compositions, from solids exclusively formed from pure condensates or from nearly exclusively clathrates, the latter case providing a slightly better fit. The total mass of volatiles needed in the envelope of Jupiter to match the observed enrichments is within the 4.3-39 Mearth range, depending on the crystallization scenario considered in the protosolar nebula. A wide range of masses of heavy elements derived from our fits is found compatible with the envelope's metallicity calculated from current interior models.

title: Democratic Political Economy of Financial Regulation

description: "The imposition of adequate regulation on banks and other financial institutions is crucial to maintain the stability of the financial system and macroeconomy. This is because participants in financial markets often have incentives that are not aligned with what is good for society.

Many have argued that insufficient prudential regulation contributed to the 2008 sub-prime mortgage crisis in the United States. However, there is less discussion on why the US government failed to regulate banks and other financial institutions to prevent the crisis.

In this paper, we show that such “regulatory failure” could be an outcome of a democratic political process. This occurs when the beneficiaries of such policy—existing home-owners, who benefit from the increased house prices, and wealth-poor home-buyers, who benefit from lower mortgage interest rates—outnumber its opponents—wealthy buyers and renters, who get exposed to the fragility of the financial system."

description: "L’imposition d’une réglementation adéquate aux banques et autres institutions financières est essentielle pour maintenir la stabilité du système financier et de la macroéconomie. Cela tient au fait que les participants aux marchés financiers ont souvent des motifs qui ne correspondent pas avec le bien de la société.

Beaucoup ont affirmé que la réglementation prudentielle insuffisante a contribué à la crise des prêts hypothécaires à risque de 2008 aux États-Unis. Cependant, les raisons pour lesquelles le gouvernement américain n’a pas réussi à réglementer les banques et les autres institutions financières afin d’éviter la crise n’ont pas fait l’objet d’autant de discussions.

Dans la présente étude, nous montrons qu’un tel « échec de réglementation » pourrait résulter de l’appareil politique démocratique. Cela se produit lorsque les bénéficiaires d’une réglementation financière laxiste – les propriétaires occupants, qui profitent de la hausse des prix des maisons, et les acheteurs de maisons peu fortunés, qui tirent parti des taux hypothécaires plus bas – sont plus nombreux que ceux qui ne sont pas avantagés par celle-ci – les acheteurs et locataires riches, qui sont exposés à la fragilité du système financier."
On the path structure of a semimartingale arising from monotone probability theory

description: Let $X$ be the unique normal martingale such that $X_0=0$ and \[\mathrm{d}[X]_t=(1-t-X_{t-}) \mathrm{d}X_t+\mathrm{d}t\] and let $Y_t:=X_t+t$ for all $t\geq 0$; the semimartingale $Y$ arises in quantum probability, where it is the monotone-independent analogue of the Poisson process. The trajectories of $Y$ are examined and various probabilistic properties are derived; in particular, the level set $\{t\geq 0\dvt Y_t=1\}$ is shown to be non-empty, compact, perfect and of zero Lebesgue measure. The local times of $Y$ are found to be trivial except for that at level 1; consequently, the jumps of $Y$ are not locally summable.

description: Проведено исследование штаммовой вариабельности грибов Aspergillus niger по их устойчивости к биоциду Rocima GT (метатин) и образованию органических кислот под действием этого биоцида. Устойчивость к биоциду Rocima GT (метатин) коррелирует с физиологическими особенностями штаммов Aspergillus niger, в частности с процессами энергетического обмена. Наибольшей устойчивостью к действию метатина обладают штаммы, выделенные с минерального субстрата.
Creators and consecrators : a potter community of South India
Creators: name: Inglis, Stephen Robert
Publisher: name: University of British Columbia
Year: 2010

description: This thesis presents the first extended ethnographic account of a potter community in India. The research material which is presented and analysed was gathered during 1979-1980 in the South Indian state of Tamil Natu. The cultural context of the craftwork of the potters is described and interpreted through a detailed study of a potter community. The central aim of this thesis is to demonstrate, through an investigation of cultural meaning, the ways in which the diverse aspects of the potters' craft are bound together. An attempt is made to demonstrate how the potters' work of pot making, image making, and priestly service all address a single core of the ideas and how these are deeply rooted in a more general pattern of Indian belief about existence. The special skill of potters to manifest these ideas, and the role of their craft in helping to regenerate and sustain them is discussed. The interpretation and analysis presented in this thesis is informed by a number of sources: the views expressed by potters and those of people who utilize their services, sources on Indian history and ethnology, and those on the study of art in anthropology. The thesis presents an analysis of one of the most ancient and broadly-based craft traditions in India and interprets its cultural meaning in South Indian life.

The post-main-sequence fate of the HR 8799 planetary system

description: The noteworthy four-planet HR 8799 system teeters on the brink of gravitational instability and contains an A-type host star which is characteristic of the progenitors of the majority of known white dwarf planetary system hosts. Gozdziewski and Migaszewski (2020) have demonstrated that the system can retain all four planets for at least 1 Gyr along the main sequence if the planets evolve within an externally unperturbed 8:4:2:1 mean motion resonance configuration. Here we propagate forward their most stable fit beyond the main sequence, and incorporate external effects from Galactic tides and stellar flybys. We find that (i) giant branch mass loss always breaks the resonance, and usually triggers the ejection of two of the planets, (ii) stellar flybys and Galactic tides rarely break the resonance during the main-sequence and giant branch phases, but play a crucial role in determining the final planetary configurations around the eventual white dwarf host star, and (iii) the meanderings of the surviving planets vary significantly, occupying regions from under 1 au to thousands of au. The ubiquitous survival of at least one planet and the presence of the debris discs in the system should allow for dynamical pathways for the white dwarf to be metal-polluted.

description: We study cosmic Nielsen-Olesen strings in space-times with a positive cosmological constant. For the free cosmic string in a cylindrically symmetric space-time, we calculate the contribution of the cosmological constant to the angle deficit, and to the bending of null geodesics. For a cosmic string in a Schwarzschild-de Sitter space-time, we use Kruskal patches around the inner and outer horizons to show that a thin string can pierce them.

description: Confortés par leurs propres théories, les économistes classiques, à l’exception de Malthus peut-être, étaient certains que l’humain était en capacité de créer sur terre une utopie paradisiaque basée sur l’idée que l’accélération de l’activité économique conduirait à l’abondance matérielle et à l’équilibre, sans qu’ aucun ne puisse imaginer que cette accélération poussée à l’extrême, puisse avoir un si lourd impact environnemental. Les concepts défendus par les classiques ont eu pour effet, entre autres, d’introduire à une hauteur vertigineuse la compétition entre les agents économiques en développant à un rythme sans précédent la production et surtout la productivité. Le mécanisme de marché, devenu la « main invisible » smithienne régule l’offre et la demande, la recherche de l’intérêt personnel devant conduire à une amélioration régulière du bien-être et à l’intérêt général. Libre concurrence et compétition sont au centre de la théorie économique dominante d’alors...

description: Исследования показали перспективность использования газофазной полимеризации парилена для консервации таких артефактов, как сильно деформированная сгоревшая бумага, восковые или сургучные печати. Нанесение парилена на обугленный остов сгоревшей бумаги упрочняет ее, фиксируя форму. Появляется возможность развернуть образовавшийся композиционный материал для последующей работы по выявлению текста. Парилен фиксирует части расколотой и смонтированной на документе сургучной печати или выкрашивающиеся фрагменты сильно состарившейся восковой, предотвращая их дальнейшее разрушение.
Melnikov method for non-conservative perturbations of the three-body problem

description: We consider the planar circular restricted three-body problem (PCRTBP), as a model for the motion of a spacecraft relative to the Earth-Moon system. We focus on the Lagrange equilibrium points $L_1$ and $L_2$. There are families of Lyapunov periodic orbits around either $L_1$ or $L_2$, forming Lyapunov manifolds. There also exist homoclinic orbits to the Lyapunov manifolds around either $L_1$ or $L_2$, as well as heteroclinic orbits between the Lyapunov manifold around $L_1$ and the one around $L_2$. The motion along the homoclinic/heteroclinic orbits can be described via the scattering map, which gives the future asymptotic of a homoclinic orbit as a function of the past asymptotic. In contrast with the more customary Melnikov theory, we do not need to assume that the asymptotic orbits have a special nature (periodic, quasi-periodic, etc.). We add a non-conservative, time-dependent perturbation, as a model for a thrust applied to the spacecraft for some duration of time, or for some other effect, such as solar radiation pressure. We compute the first order approximation of the perturbed scattering map, in terms of fast convergent integrals of the perturbation along homoclinic/heteroclinic orbits of the unperturbed system. As a possible application, this result can be used to determine the trajectory of the spacecraft upon using the thrust.
Noncollinear ferrielectricity and morphotropic phase boundary in GeS monolayer

description: Two-dimensional polarity is intriguing but remains in the early stage. Here a structural evolution diagram is established for GeS monolayer, which leads a noncollinear ferrielectric $δ$-phase energetically as stable as the ferroelectric $α$-phase. Its ferrielectricity is induced by the phonon frustration, i.e., the competition between ferroelectric and antiferroelectric modes, providing more routes to tune its polarity. Besides its prominent properties like large band gap, large polarization, and high Curie temperature, more interestingly, the morphotropic phase boundary between $α$- and $δ$-phases is highly possible, which is crucial to obtain giant piezoelectricity for lead-free applications.

The Coexistence of Classical Bulges and Disky Pseudobulges in Early-Type Disk Galaxies

Publisher: name: arXiv

description: Close examination of so-called "pseudobulges" in several early-type disk galaxies indicates that they are actually composite structures consisting of both a flattened, kinematically cool disklike structure ("disky pseudobulge") and a rounder, kinematically hot spheroidal structure ("classical bulge"). This indicates that pseudobulges, thought to form from internal secular evolution, and classical bulges, thought to form from rapid mergers, are not exclusive phenomena: some galaxies can have both.
