description: We present the results of EVN polarization observations of fourteen GHz-Peaked-Spectrum (GPS) radio sources at 5 GHz. These sources were selected from bright GPS source samples and we aimed at finding Compact Symmetric Objects (CSOs). We have obtained full polarization 5 GHz VLBI observations of 14 sources providing information on their source structure and spectral indices. The results show that two core-jet sources 1433$-$040 and DA193, out of 14 GPS sources, exhibit integrated fractional polarizations of 3.6% and 1.0% respectively. The other 12 sources have no clear detection of pc-scale polarization. The results confirm that the GPS sources generally have very low polarization at 5 GHz. The sources 1133+432, 1824+271 and 2121$-$014 are confirmed as CSOs. Three new CSOs 0914+114, 1518+046 and 2322$-$040 (tentative) have been classified on the basis of 5 GHz images and spectral indices. The sources 1333+589, 1751+278 and 2323+790 can be classified either as compact doubles, and then they are likely CSO candidates or core-jet sources; further observations are needed for an appropriate classification; 0554$-$026, 1433$-$040 and 1509+054 are core-jet sources. In addition, we estimate that a component in the jet of quasar DA193 has superluminal motion of $3.3\pm0.6 h^{-1}c$ in 5.5 years.

title: Der Einfluss des räumlichen Denkens auf die Maturanote im Fach Mathematik
Creators: name: Reiner, Raphael
Year: 2024

description: Die Thematik des räumlichen Denkens hat bereits eine lange Forschungsgeschichte hinter sich und dennoch gibt es immer wieder neue Erkenntnisse dazu. Hierzu konnten vor allem die technischen Entwicklungen der letzten Jahrzehnte nicht nur ihren Teil dazu beitragen, sondern veränderten auf ihre Weise das Themenfeld, siehe Virtual Reality. Das räumliche Denken ist eine Fähigkeit, die von allen Menschen in vielen unterschiedlichen Lebenssituationen Anwendung findet – wenn auch oftmals nicht bewusst. Gerade deswegen ist das räumliche Denken eine interessante Fähigkeit, die immer wieder untersucht worden ist. In der langen Forschungsgeschichte des räumlichen Denkens konnte in den letzten Jahrzehnten gut gezeigt werden, dass diese Fähigkeit auch ein wichtiger Indikator dafür ist, ob Menschen im MINT- Bereich (Mathematik, Informatik, Naturwissenschaften und Technik) studieren oder arbeiten werden. In vielen Studien wurde hierzu nachgewiesen, dass eine hervorragende Fähigkeit zum räumlichen Denken den Erfolg im MINT-Bereich vorhersagen kann. Eine gemeinsame Disziplin, die in jedem MINT-Bereich Anwendung findet, ist die Mathematik. Aus diesem Grund wird sich die folgende Masterarbeit damit beschäftigen, ob sich durch eine gute Fähigkeit zum räumlichen Denken auch Mathematikleistungen vorhersagen lassen. Um diese Annahme überprüfen zu können, wurde die Fähigkeit zum räumlichen Denken und die Mathematikleistungen von Personen, die die Matura auf zweitem Bildungsweg – Lehre mit Matura oder Berufsreifeprüfung – nachholen wollen, als Grundlage verwendet. Dazu wurde zum einen die Fähigkeit des räumlichen Denkens mittels Fragebogen erhoben und zum anderen die Mathematikleistungen aus der absolvierten Mathematik-Matura entnommen.

description: GEO Data Sharing Principles
Data Sharing is a pre-requisite for building an effective Global Earth Observation System of Systems. It is the backbone of the abiding GEO vision "a future wherein decisions and actions for the benefit of humankind are informed by coordinated, comprehensive and sustained Earth observations and information."
GEO recognizes that the societal benefits arising from Earth observations can only be fully achieved through the sharing of data, information, knowledge, products and services.
https://old.earthobservations.org/dswg.php
The GEO Data Management Principles build on the GEO Data Sharing Principles in the sense that they adumbrate what is required in terms of data management to allow data to be shared as Open Data, promptly and at minimum cost.  Good data management implies a number of activities which ensure that data are discoverable and accessible, that they may be understood and used, and that they are looked after in the long term.
A priority mission for GEO is to encourage the implementation of the Principles by organizations contributing to GEOSS.

The close agreement between quenched lattice QCD results with cooled and uncooled configurations for vacuum correlation functions of hadronic currents and for density-density correlation functions in hadronic bound states provides strong evidence for the dominant role of instantons in determining light hadron structure and quark propagation in the QCD vacuum.

description: Magnetometers, gyroscopes and accelerometers are commonly used sensors in a variety of applications. The paper proposes a novel gyroscope calibration method in the homogeneous magnetic field by the help of magnetometer. It is shown that, with sufficient rotation excitation, the homogeneous magnetic field vector can be exploited to serve as a good reference for calibrating low-cost gyroscopes. The calibration parameters include the gyroscope scale factor, non-orthogonal coefficient and bias for three axes, as well as its misalignment to the magnetometer frame. Simulation and field test results demonstrate the method's effectiveness.

description: We present the catalog of 477 spectra from the Serendipitous Extragalactic X-ray Source Identification (SEXSI) program, a survey designed to probe the dominant contributors to the 2-10 keV cosmic X-ray background. Our survey covers 1 deg^2 of sky to 2-10 keV fluxes of 10^-14 erg cm^-2 s^-1, and 2 deg^2 for fluxes of 3 x 10^-14 erg cm^-2 s^-1. Our spectra reach to R <24 and have produced redshifts for 438 hard X-ray sources. The vast majority of the 2-10 keV-selected sample are AGN with redshifts between 0.1 and 3. We find that few sources at z<1 have high X-ray luminosities, reflecting a dearth of high-mass, high-accretion-rate sources at low redshift, a result consistent with other recent wide-area surveys. Half of our sources show significant obscuration, with N_H>10^22 cm^-2, independent of unobscured luminosity. We classify 168 sources as emission-line galaxies; all are X-ray luminous objects with optical spectra lacking both high-ionization lines and evidence of a non-stellar continuum. The redshift distribution of these emission-line galaxies peaks at a significantly lower redshift than does that of the sources we spectroscopically identify as AGN. We conclude that few of these sources can be powered by starburst activity. Stacking spectra for a subset of these sources, we detect [Ne V] emission, a clear signature of AGN activity, confirming that the majority of these objects are Seyfert 2s in which the high-ionization lines are diluted by stellar emission. We find 33 objects lacking broad lines in their optical spectra which have quasar X-ray luminosities (Lx>10^44 erg s^-1), the largest sample of such objects identified to date. In addition, we explore 17 AGN associated with galaxy clusters and find that the cluster-member AGN sample has a lower fraction of broad-line AGN than does the background sample.

description: Diffusion MRI (dMRI) is a valuable tool in the assessment of tissue microstructure. By fitting a model to the dMRI signal it is possible to derive various quantitative features. Several of the most popular dMRI signal models are expansions in an appropriately chosen basis, where the coefficients are determined using some variation of least-squares. However, such approaches lack any notion of uncertainty, which could be valuable in e.g. group analyses. In this work, we use a probabilistic interpretation of linear least-squares methods to recast popular dMRI models as Bayesian ones. This makes it possible to quantify the uncertainty of any derived quantity. In particular, for quantities that are affine functions of the coefficients, the posterior distribution can be expressed in closed-form. We simulated measurements from single- and double-tensor models where the correct values of several quantities are known, to validate that the theoretically derived quantiles agree with those observed empirically. We included results from residual bootstrap for comparison and found good agreement. The validation employed several different models: Diffusion Tensor Imaging (DTI), Mean Apparent Propagator MRI (MAP-MRI) and Constrained Spherical Deconvolution (CSD). We also used in vivo data to visualize maps of quantitative features and corresponding uncertainties, and to show how our approach can be used in a group analysis to downweight subjects with high uncertainty. In summary, we convert successful linear models for dMRI signal estimation to probabilistic models, capable of accurate uncertainty quantification.

Search for higgsino pair production in pp collisions at sqrt(s) = 13 TeV in final states with large missing transverse momentum and two Higgs bosons decaying via H to bb-bar

description: Results are reported from a search for new physics in 13 TeV proton-proton collisions in the final state with large missing transverse momentum and two Higgs bosons decaying via H to bb-bar. The search uses a data sample accumulated by the CMS experiment at the LHC in 2016, corresponding to an integrated luminosity of 35.9 inverse femtobarns. The search is motivated by models based on gauge-mediated supersymmetry breaking, which predict the electroweak production of a pair of higgsinos, each of which can decay via a cascade process to a Higgs boson and an undetected lightest supersymmetric particle. The observed event yields in the signal regions are consistent with the standard model background expectation obtained from control regions in data. Higgsinos in the mass range 230-770 GeV are excluded at 95% confidence level in the context of a simplified model for the production and decay of approximately degenerate higgsinos.

Impossibility of partial swapping of Quantum Information

description: It is a well known fact that a quantum state $|ψ(θ,ϕ)>$ are represented by a point on the Bloch sphere, characterized by two parameters $θ$ and $ϕ$. Here in this work, we find out another impossible operation in quantum information theory . We name this impossibility as 'Impossibility of partial swapping of quantum information '. By this we mean that if two unknown quantum states are given at the input port, there exists no physical process, consistent with the principles of quantum mechanics, by which we can partially swap either of the two parameters $θ$ and $ϕ$ between these two quantum states. In this work we provided the impossibility proofs for the qubits(i.e the quantum states taken from two dimensional Hilbert space) and this impossible operation can be shown to hold in higher dimension also.

A Conceptual Model for Holistic Classification of Insider

description: The process through which an insider to an organization can be described or classified is lined within the orthodox paradigm of classification in which an organization considers only subject with requisite employee criterion as an insider to that organization. This is further clouded with the relative rigidity in operational security policies being implemented in organizations. Establishing investigation process in instances of misuse occurrence and or ascertaining the efficiency of staff member using such archaic paradigm is maligned with endless possibilities of uncertainties. This study, therefore, proposes a holistic model for which insider classification can be crystallized using the combination of qualitative research process and analysis of moment structure evaluation process. A full comprehension of this proposition could serve as a hinge through which insider misuse investigation can be thoroughly carried out. In addition, integrating this paradigm into existing operational security policies could serve as a metric upon which an organization can understand insider dynamics, in order to prevent misuses, and enhance staff management.

description: The Simulation at Point1 (Sim@P1) project was built in 2013 to take advantage of the ATLAS Trigger and Data Acquisition High Level Trigger (HLT) farm. The HLT farm provides around 100,000 cores, which are critical to ATLAS during data taking. When ATLAS is not recording data, this large compute resource is used to generate and process simulation data for the experiment. At the beginning of the current long shutdown (LS2), the HLT farm including the Sim@P1 infrastructure was upgraded. Previous papers emphasized the need for "simple, reliable, and efficient tools" and assessed various options to quickly switch between data acquisition operation and offline processing. In this contribution we describe the new mechanisms put in place for the opportunistic exploitation of the HLT farm for offline processing and give results from the first months of operation.

description: Recently, a measure has been put forward which allows for the quantification of the degree of reality of an observable for a given preparation [A. L. O. Bilobran and R. M. Angelo, Europhys. Lett. 112, 40005 (2015)]. Here we employ this quantifier to establish, on formal grounds, relations among the concepts of measurement, information, and physical reality. After introducing mathematical objects that unify weak and projective measurements, we study scenarios showing that an arbitrary-intensity unrevealed measurement of a given observable generally leads to an increase of its reality and also of its incompatible observables. We derive a complementarity relation connecting an amount of information associated with the apparatus with the degree of irreality of the monitored observable. Specifically for pure states, we show that the entanglement with the apparatus precisely determines the amount by which the reality of the monitored observable increases. We also point out some mechanisms whereby the irreality of an observable can be generated. Finally, using the aforementioned tools, we construct a consistent picture to address the measurement problem.

description: We present a class of nonsingular, bouncing cosmologies that evade singularity theorems through the use of vorticity in compact extra dimensions. The vorticity combats the focusing of geodesics during the contracting phase. The construction requires fluids that violate the null energy condition (NEC) in the compact dimensions, where they can be provided by known stable NEC violating sources such as Casimir energy. The four dimensional effective theory contains an NEC violating fluid of Kaluza-Klein excitations of the higher dimensional metric. These spacetime metrics could potentially allow dynamical relaxation to solve the cosmological constant problem. These ideas can also be used to support traversable Lorentzian wormholes.

description: Estimations of the CPU resources that will be needed to produce simulated data for the future runs of the ATLAS experiment at the LHC indicate a compelling need to speed-up the process to reduce the computational time required. While different fast simulation projects are ongoing (FastCaloSim, FastChain, etc.), full Geant4 based simulation will still be heavily used and is expected to consume the biggest portion of the total estimated processing time. In order to run effectively on modern architectures and profit from multi-core designs, a migration of the Athena framework to a multi-threading processing model has been performed in the last years. A multi-threaded simulation based on AthenaMT and Geant4MT enables substantial decreases in the memory footprint of jobs, largely from shared geometry and cross-sections tables. This approach scales better with respect to the multi-processing approach (AthenaMP) especially on the architectures that are foreseen to be used in the next LHC runs. In this paper we will report about the status of the multithreaded simulation in ATLAS, focusing on the different challenges of its validation process. We will demonstrate the different tools and strategies that have been used for debugging multi-threaded runs versus the corresponding sequential ones, in order to have a fully reproducible and consistent simulation result.
High-Rate Entanglement Source via Two-Photon Emission from Semiconductor Quantum Wells

description: We propose a compact high-intensity room-temperature source of entangled photons based on the efficient second-order process of two-photon spontaneous emission from electrically-pumped semiconductor quantum wells in a photonic microcavity. Two-photon emission rate in room-temperature semiconductor devices is determined solely by the carrier density, regardless of the residual one-photon emission. The microcavity selects two-photon emission for a specific signal and idler wavelengths and at a preferred direction without modifying the overall rate. Pair-generation rate in GaAs/AlGaAs quantum well structure is estimated using a 14-band model to be 3 orders of magnitude higher than for traditional broadband parametric down-conversion sources.
FullSimLight: ATLAS standalone Geant4 simulation

Publisher: name: Zenodo
Year: 2019

description: HEP experiments simulate the detector response by accessing all needed data and services within their own software frameworks. However, decoupling the simulation process from the experiment infrastructure can be useful for a number of tasks, amongst them the debugging of new features, or the validation of multithreaded vs sequential simulation code and the optimization of algorithms for HPCs. The relevant features and data must be extracted from the framework to produce a standalone simulation application. As an example, the simulation of the detector response of the ATLAS experiment at the LHC is based on the Geant4 toolkit and is fully integrated in the experiment's framework "Athena". Recent developments opened the possibility of accessing a full persistent copy of the ATLAS geometry outside of the Athena framework. This is a prerequisite for running ATLAS Geant4 simulation standalone. In this talk we present the status of development of FullSimLight, a full simulation prototype that is being developed with the goal of running ATLAS standalone Geant4 simulation with the actual ATLAS geometry. The purpose of FullSimLight is to simplify studies of Geant4 tracking and physics processes, including on novel architectures. We will also address the challenges related to the complexity of ATLAS's geometry implementation, which precludes persistifying a complete detector description in a way that can be automatically read by standalone Geant4. This lightweight prototype is meant to ease debugging operations on the Geant4 side and to allow early testing of new Geant4 releases. It will also ease optimization studies and R&D activities related to HPC development: i.e. the possibility to offload partially/totally the simulation to GPUs/Accelerators without having to port the whole experimental infrastructure.

description: We propose a new smoothing method for obtaining surface densities from discrete particle positions from numerical simulations. This is an essential step for many applications in gravitational lensing. This method is based on the ``scatter'' interpretation of the discrete density field in the Smoothed Particle Hydrodynamics. We use Monte Carlo simulations of uniform density fields and one isothermal ellipsoid to empirically derive the noise properties, and best smoothing parameters (such as the number of nearest neighbors used). A cluster from high-resolution simulations is then used to assess the reality of high-order singularities such as swallowtails and butterflies in caustics, which are important for the interpretation of substructures in gravitational lenses. We also compare our method with the Delaunay tesselation field estimator using the galaxy studied by Bradac et al. (2004), and find good agreements. We show that higher order singularities are not only connected with bound subhaloes but also with the satellite streams. However, the presence of high-order singularities are sensitive to not only the fluctuation amplitude of the surface density, but also the detailed form of the underlying smooth lensing potential (such as ellipticity and external shear).

We present a newly collected police fatality corpus, which we release publicly, and present a model to solve this problem that uses EM-based distant supervision with logistic regression and convolutional neural network classifiers. Our model outperforms two off-the-shelf event extractor systems, and it can suggest candidate victim names in some cases faster than one of the major manually-collected police fatality databases.

The swimming mode of wild-type E.coli is often idealized as a "run-and- tumble" sequence in which periods of swimming at a constant speed are randomly interrupted by a sudden change of direction at a very low speed. Using a tracking microscope, we follow cells for extended periods of time in Newtonian liquids of varying viscosity, and find that the swimming behavior of a single cell can exhibit a variety of behaviors including run-and-tumble and "slow-random-walk" in which the cells move at relatively low speed. Although the characteristic swimming speed varies between individuals and in different polymer solutions, we find that the skewness of the speed distribution is solely a function of viscosity and can be used, in concert with the measured average swimming speed, to determine the effective running speed of each cell. We hypothesize that differences in the swimming behavior observed in solutions of different viscosity are due to changes in the flagellar bundling time, which increases as the viscosity rises, due to the lower rotation rate of the flagellar motor. A numerical simulation and the use of Resistive Force theory provide support for this hypothesis.

description: It is well known that finite commutative association schemes in the sense of the monograph of Bannai and Ito lead to finite commutative hypergroups with positive dual convolutions and even dual hypergroup structures. In this paper we present several discrete generalizations of association schemes which also lead to associated hypergroups. We show that discrete commutative hypergroups associated with such generalized association schemes admit dual positive convolutions at least on the support of the Plancherel measure. We hope that examples for this theory will lead to the existence of new dual positive product formulas in near future.

description: We have previously established, from a carbon star survey, that the Local Group dwarf irregular galaxy NGC 6822 is much larger than its central bright core. Four MegaCam fields are acquired to survey a 2$^\circ\times$ 2$^\circ$ area centred on NGC 6822 to fully determine its extent and map its stellar populations. Photometry of over one million stars is obtained in the SDSS g$'$, r$'$, i$'$ to three magnitudes below the TRGB. RGB stars, selected from their magnitudes and colours, are used to map the NGC 6822 stellar distribution up to a distance of 60 arcmin. We map the reddening over the whole area. We establish that the stellar outer structure of NGC 6822 is elliptical in shape, with $ε=0.36$ and a major-axis PA = 65$^\circ$, contrasting with the orientation of the HI disk. The density enhancement can be seen up to a semi-major axis of 36$'$ making NGC 6822 as big as the Small Magellanic Cloud. We fit two exponentials to the surface density profile of the spheroid, and identify a bulge with a scale length of 3.85$'$ and an outer spheroid with a scale length of 10.0$'$. We find intermediate-age C stars up to $\sim$ 40$'$ while demonstrating that the SDSS filters are unsuitable to identify extragalactic C stars. NGC 6822 is a unique Local Group galaxy with shape and structure suggesting a polar ring configuration. Radial velocities of carbon stars have indeed demonstrated that there are two kinematical systems in NGC 6822.

Density matrix approach to photon-assisted tunneling in the transfer Hamiltonian formalism

description: The transfer Hamiltonian tunneling current is derived in a time-dependent density matrix formulation and is used to examine photon-assisted tunneling. Bardeen's tunneling expression arises as the result of first order perturbation theory in a mean-field expansion of the density matrix. Photon-assisted tunneling from confined electromagnetic fields in the forbidden barrier region occurs due to time-varying polarization and wavefunction overlap in the gap, which leads to a non-zero tunneling current in asymmetric device structures, even in an unbiased state. The photon energy is seen to act as an effective temperature dependent bias in a uniform barrier asymmetric tunneling example problem. Higher order terms in the density matrix expansion give rise to multi-photon enhanced tunneling currents that can be considered an extension of non-linear optics where the non-linear conductance plays a similar role as the non-linear susceptibilities in the continuity equations.

description: Mapping of ERA-5 hourly surface wind shifts in the Bay of Biscay during 85 galerna events (2003-2020), including the galerna (86), which occurred on July 25, 1995. The Front Identification Scheme (FIS), developed to draw tracks of cold fronts over the sea, has revealed an active frontogenesis in the interior of the Bay of Biscay of these short-lived fronts. (g1) stands for Grid 1, which includes a large part of Europe and North Africa, while (g2) stands for Grid 2, an area centered on the Bay of Biscay, southern France, and northern Iberia.

The FIS software is designed to detect wind shifts, from the southwest quadrant to the northwest, in the increase of the northern component (shaded colors in ms-1), between consecutive wind fields separated by two hours. A 2 m s-1 theshold increase of the merridional component is use to plot this type of fronts. In addition, east-west wind shifts are plotted on the same figures, using a similar 2 m s-1 threshold increase in the zonal wind component (contour lines) between the same consecutive wind fields.

Surface pressure charts with fronts on a selection of days are included for comparison. They can be download from https://www2.wetter3.de/

description: A high statistics calculation, performed at $β=5.74,\;6.00$ and $6.26$, enables us to study the variation of the leptonic decay constants $f_P$ of heavy pseudoscalar mesons with the lattice spacing $a$. We observe only a weak $a$ dependence when the standard $\sqrt{2κ}$ normalization is used for the quark fields, whereas application of the Kronfeld-Mackenzie normalization induces a stronger variation with $a$. Increasing the meson mass from $1.1GeV$ to $2.3GeV$ this situation becomes even more pronounced.

description: We formulate a renormalized running coupling expansion for the $β$--function and the potential of the renormalized $ϕ^4$--trajectory on four dimensional Euclidean space-time. Renormalization invariance is used as a first principle. No reference is made to bare quantities. The expansion is proved to be finite to all orders of perturbation theory. The proof includes a large momentum bound on the connected free propagator amputated vertices.

Seed-associated bacterial endophytes from turf grasses promote seedling growth and defend plants from disease
Creators: name: Chen, Qiang
Publisher: name: No Publisher Supplied
Year: 2020

description: Animals and plants harbor microbiomes providing benefits to hosts. In plants, both prokaryotic and eukaryotic microbiomes have been universally found and shown to promote plant growth, enhance disease resistance and abiotic stress tolerance. Fungal endophytes from grasses have been well characterized, but bacterial endophytes were rarely studied. This dissertation will present research that was conducted to test the hypothesis that cool-season turfgrass seeds bear bacterial endophytes providing beneficial effects on host, such as seed germination, growth promotion, and antifungal effects. Bacteria were isolated from seeds of different turfgrass species. Among them, Bacillus amyloliquefaciens, Bacillus pumilus, and Pantoea agglomerans were demonstrated to promote seed germination and seedling growth, and alter root architecture on host. B. amyloliquefaciens strains were shown to produce antifungal lipopeptides that suppress the growth of several fungal pathogens. Metagenomic analysis on the bacterial community associated with turfgrass seeds from low and high moisture climate revealed that moisture level influenced the community structure of the bacteria on/in turf seeds. The abundance of several bacterial groups at different taxonomy ranks on/in the seeds was either positively or negatively correlated with the seed germination rate. Overall, data supported that bacterial endophytes inhabiting turfgrass seeds benefited host by promoting seed germination and seedling development, as well as providing antifungal compounds. Moreover, moisture level was found to affect the structure of bacterial community on/in turfgrass seed, which further influenced the seed germination.

description: We present 0.5" resolution near-IR integral field spectroscopy of the Ha line emission of 14 z~2 UV-selected BM/BX galaxies obtained with SINFONI at ESO/VLT. The mean Ha half-light radius r_1/2 is about 4kpc and line emission is detected over > ~20kpc in several sources. In 9 sources, we detect spatially-resolved velocity gradients, from 40 to 410 km/s over ~10kpc. The observed kinematics of the larger systems are consistent with orbital motions. Four galaxies are well described by rotating disks with clumpy morphologies and we extract rotation curves out to radii > ~10kpc. One or two galaxies exhibit signatures more consistent with mergers. Analyzing all 14 galaxies in the framework of rotating disks, we infer mean inclination- and beam-corrected maximum circular velocities v_c of 180+-90 km/s and dynamical masses of (0.5-25)x10^10 Msun within r_1/2. On average, the dynamical masses are consistent with photometric stellar masses assuming a Chabrier/Kroupa IMF but too small for a 0.1-100 Msun Salpeter IMF. The specific angular momenta of our BM/BX galaxies are similar to those of local late-type galaxies. The specific angular momenta of their baryons are comparable to those of their dark matter halos. Extrapolating from the average v_c at 10kpc, the virial mass of the typical halo of a galaxy in our sample is 10^(11.7+-0.5) Msun. Kinematic modeling of the 3 best cases implies a ratio of v_c to local velocity dispersion of order 2-4 and accordingly a large geometric thickness. We argue that this suggests a mass accretion (alternatively, gas exhaustion) timescale of ~500Myr. We also argue that if our BM/BX galaxies were initially gas rich, their clumpy disks will subsequently lose their angular momentum and form compact bulges on a timescale of ~1 Gyr. [ABRIDGED]
