description: L'ensemble de ces notes ont été crée par John Baldwin lors d'une de ses premières périodes de résidence à Paris. Ces documents comprennent tous les magistri qu’il avait pu rencontrer dans ses sources. Aux XIIème et XIIIème siècles, les universités n'existant pas encore, le titre de magister s'il évoque certainement une compétence n'est pas rattaché de façon systématique au passage par les écoles. De surcroît, les magistris sont le plus souvent désignés par leur seul prénom. La lecture de ces données est donc difficile et suppose un long travail pour tenter d'identifier un individu auquel on pourrait rattacher plusieurs mentions. John Baldwin avait donc renoncé à utiliser ces données pour donner un prolongement à sa magnifique étude sur les gradués d'université et leur emploi par les Capétiens et les Plantagenêts. Néanmoins, il a conservé ces données et elles sont potentiellement très utile dans le cadre de Studium, comme le sont toutes les mentions dans les volumes des Fasti Ecclesiae Gallicanae de chanoines portant ce titre de magister sans autres précisions. L'ampleur des dépouillements rend ces données très utiles et nous devons une grande reconnaissance à John Baldwin pour avoir pris la peine de faire photocopier ses fiches et de nous les avoir transmises amicalement.

description: We study analytically the radial Schrödinger equation with long-range attractive potentials whose asymptotic behaviors are dominated by inverse power-law tails of the form $V(r)=-β_n r^{-n}$ with $n>2$. In particular, assuming that the effective radial potential is characterized by a short-range infinitely repulsive core of radius $R$, we derive a compact {\it analytical} formula for the threshold energy $E^{\text{max}}_l=E^{\text{max}}_l(n,β_n,R)$ which characterizes the most weakly bound-state resonance (the most excited energy level) of the quantum system.

Low-frequency attenuation measurements of fluids

description: Pore fluids significantly affect the elastic responses of rocks. Rock-physics models can be used to predict how pore fluids affect the elastic responses of fully or partially saturated rocks. Thus, to identify fluids in the subsurface, knowing the anelastic properties of such fluids, such as attenuation, is useful. In addition, new technologies to assess and monitor hydrocarbon exploration rely on the precise determination of the anelastic properties of hydraulic fracturing fluids. Moreover, the anelastic properties of fluids depend on the frequency of the wave propagating through the fluid. Methodologies to measure high-frequency anelastic properties of fluids have been widely reported. What have not been established are methodologies to measure the low-frequency anelastic properties and attenuation of fluids in a laboratory setting, aside from shear viscosity. Using the low-frequency properties and attenuation, rather than the already known high-frequency properties of pore fluids, will provide more accurate estimates for rock physics models and seismic data. To address this situation, a laboratory machine has been designed, built, and calibrated to measure the low-frequency attenuation and bulk modulus of fluids at frequencies from 0.1 to 10 Hz. Deionized water and aqueous guar gum solutions have been tested. Results for measurements of attenuation and bulk modulus of water agree with the literature. Measurements of guar gum solutions show that attenuation is greater than 0.01 with higher concentration samples having higher attenuation. This might be explained by energy being lost during the breakup of weak and strong bonds in the guar gum polymer chains. A higher concentration provides more bonds to break up which leads to more energy being lost which increases attenuation. The present study will help improve seismic methods and rock physics models by incorporating low-frequency attenuation values of fluids.

The Galactic Center He I Stars: Remains of a Dissolved Young Cluster?
Creators: name: Gerhard, Ortwin
Publisher: name: arXiv
Year: 2000
Subjects: subject: Astrophysics (astro-ph)
subject: FOS: Physical sciences

description: A massive young star cluster, initially embedded in its parent molecular cloud, will spiral into the Galactic Center from $\lta 30m_6^{1/2}\pc$ during the life-time of its most massive stars, if the combined total mass is $\sim 10^6m_6\msun$. On its way inwards the system loses most of its mass to the strong tidal field, until the dense cluster core of high-mass stars is finally disrupted near the central black hole. A simple model is presented to argue that this scenario may under plausible conditions explain the observed location and rotation of the Galactic Center HeI stars. Accretion of star clusters into the Galactic Center could be recurrent, and play an important role in regulating the activity of Sgr A$^\ast$.

description: Siphunculina brevinervis Rondani, 1856
ORIGINAL DESCRIPTION: 1856: 128.
TYPE LOCALITY: Rondani gave no type locality in his original description but presumably it is Italy because the work deals with Italian species.
 TYPE MATERIAL: 3 ♀♀, 1 specimen, syntypes (sex not determinable, damaged) (MZUF: Box 38): Siphunculina Rndn. / brevinervis Rnd. / 2058; 1 ♀, syntype (slightly moldy, missing left mid-leg) (OUMNH Verrall-Collin Coll.: Box. 18): Type / Siphunculina brevinervis Rond. Ex. Coll. Big. / S. brevinervis Parma, Rond. / G. Siphunculina Rondani.
 CURRENT STATUS: junior synonym of Siphunculina aenea (Macquart, 1835) (Nartshuk 1984b: 256).
 REMARKS: Rondani’s (1856: 128) key for the genus Siphunculina Rondani, 1856 lists Siphunculina brevinervis as its type species, but he did not provide a detailed description, type locality, number or sex of the specimens. Five syntypes were found in this study.

description: We present the latest lattice QCD results for baryon interactions obtained at nearly physical quark masses. $N_f = 2+1$ nonperturbatively ${\cal O}(a)$-improved Wilson quark action with stout smearing and Iwasaki gauge action are employed on the lattice of $(96a)^4 \simeq (8.1\mbox{fm})^4$ with $a^{-1} \simeq 2.3$ GeV, where $m_π\simeq 146$ MeV and $m_K \simeq 525$ MeV. In this report, we study the two-nucleon systems and two-$Ξ$ systems in $^1S_0$ channel and $^3S_1$-$^3D_1$ coupled channel, and extract central and tensor interactions by the HAL QCD method. We also present the results for the $NΩ$ interaction in $^5S_2$ channel which is relevant to the $NΩ$ pair-momentum correlation in heavy-ion collision experiments.

description: It is known that hidden U(1) gauge factors can couple to visible U(1)'s through Kinetic Mixing. This phenomenon is shown generically to occur in nonsupersymmetric string set-ups, between branes and antibranes. Kinetic Mixing acts either to give millicharges (of e.g. hypercharge) to would-be hidden sector fermions, or to generate an enhanced communication of supersymmetry breaking that dominates over the usual gravitational suppression. In either case, the conclusion is that the string scale in nonsupersymmetric brane configurations has a generic upper bound of M_s

Coherence Network in the Quantum Hall Bilayer

description: Recent experiments on quantum Hall bilayers near total filling factor 1 have demonstrated that they support an ``imperfect'' two-dimensional superfluidity, in which there is nearly dissipationless transport at non-vanishing temperature observed both in counterflow resistance and interlayer tunneling. We argue that this behavior may be understood in terms of a {\it coherence network} induced in the bilayer by disorder, in which an incompressible, coherent state exists in narrow regions separating puddles of dense vortex-antivortex pairs. A renormalization group analysis shows that it is appropriate to describe the system as a vortex liquid. We demonstrate that the dynamics of the nodes of the network leads to a power law temperature dependence of the tunneling resistance, whereas thermally activated hops of vortices across the links control the counterflow resistance.

description: We prove global existence of weak solutions to two systems of equations which extend the dynamics of the Navier-Stokes equations for incompressible viscous flow with no-slip boundary condition. The systems of equations we consider arise as formal limits of time discrete pressure-Poisson schemes introduced by Johnston and Liu (J. Comp. Phys. 199 (2004) 221-259) and by Shirokoff and Rosales (J Comp. Phys 230 (2011) 8619-8646) when the initial data does not satisfy the required compatibility condition. Unlike the results of Iyer et al (J. Math. Phys. 53 (2012) 115605), our approach proves existence of weak solutions in domains with less than C^1 regularity. Our approach also addresses uniqueness in 2D and higher regularity.
Geology of Killam deep test near Valentine, Jeff Davis County, Trans-Pecos, Texas

description: The Killam deep test, located one mile northeast of Valentine, penetrated the thickest sequence of Tertiary volcanic rocks (more than 6,000 feet) known in Trans-Pecos Texas. The unusual thickness is attributed to deposition in a shallow basin that subsided throughout Tertiary time and to preservation in the structural low which was folded and faulted in late Tertiary time. Adjacent areas to the north and west were uplifted, while the basin near Valentine was downwarped. During the Quaternary period the basin received alluvial sediments from the nearby hills; more than 500 feet of alluvium was penetrated by the Killam well. Examination of well cuttings and thin sections of cuttings indicates eighteen volcanic units tentatively correlated with other volcanic rocks of the region.

Στα πρώτα κεφάλαια αναλύεται το θεωρητικό υπόβαθρο όσον αφορά στην γένεση και τη δομή των αργιλικών ορυκτών, τους τρόπους γένεσης των κοιτασμάτων μπεντονίτη, η ταξινόμηση των μπεντονιτών οι χρήσεις καθώς και οι ιδιότητες των μπεντονιτών και τέλος το ΦΚΔ καθώς και οι μέθοδοι προσδιορισμού του.
Στη συνέχεια περιγράφονται οι πειραματικές τεχνικές που ακολουθήθηκαν, και πιο συγκεκριμένα η μέθοδος που χρησιμοποιήθηκε για τον προσδιορισμό του ΦΚΔ των σμεκτιτών. Πιο συγκεκριμένα, κατά τη διάρκεια προετοιμασίας των δειγμάτων απομακρύνθηκε το αργιλικό κλάσμα, ακολούθησε κορεσμός με χλωριούχο κάλλιο (KCl), φυγοκέντριση των αιωρημάτων ώστε το αργιλικό κλάσμα να καθιζήσει στον πυθμένα κάθε σωλήνα και εκ νέου κορεσμός με KCl, έκπλυση των δειγμάτων από την περίσσεια KCl, τοποθέτηση δειγμάτων στους δειγματοφορείς και τέλος ακτινογράφηση με τη μέθοδο της περιθλασιμετρίας ακτίνων – Χ (XRD). Η ορυκτολογική ανάλυση των δειγμάτων πραγματοποιήθηκε με περιθλασιμετρία με βάση τα ακτινογραφήματα που προέκυψαν.
Ο προσδιορισμός του ΦΚΔ πραγματοποιήθηκε από τη θέση της βασικής ανάκλασης 001 του σμεκτίτη, σύμφωνα με την τροποποιημένη μέθοδο των Christidis & Eberl (2003). Επιπρόσθετα, το ΦΚΔ μέρους των δειγμάτων συγκρίθηκε με το ΦΚΔ που προσδιορίστηκε από άλλους ερευνητές με την κλασσική μέθοδο των Christidis & Eberl (2003), και πραγματοποιήθηκε γεωστατιστική ανάλυση των δεδομένων που περιλάμβανε αφ’ ενός σύγκριση αυτών των τιμών ΦΚΔ σε σχέση με τις τιμές ΦΚΔ που προέκυψαν από την κλασσική μέθοδο από άλλους ερευνητές και αφ’ ετέρου πρόβλεψη των τιμών ΦΚΔ σε θέσεις της τομής που δεν υπήρχαν δείγματα. Η απεικόνιση της κατανομής του φορτίου πραγματοποιήθηκε με χρήση του προγράμματος MATLAB.
Συμπερασματικά, όσον αφορά την κατανομή του ΦΚΔ του σμεκτίτη στην τομή κοιτάσματος, παρατηρούνται σμεκτίτες χαμηλού, ενδιάμεσου και υψηλού φορτίου. Πιο συγκεκριμένα, εντοπίζουμε σμεκτίτες χαμηλού φορτίου στα κεντρικά και ανατολικά τμήματα της τομής, και σμεκτίτες υψηλού φορτίου κυρίως στα ανατολικά αλλά και τα δυτικά τμήματα της τομής.

description: We report on a ROSAT PSPC observation of the highly-luminous z = 4.72 radio-loud quasar GB 1428+4217 obtained between 1998 December 11 and 17, the final days of the ROSAT satellite. The low-energy sensitivity of the PSPC detector was employed to constrain the intrinsic X-ray absorption of the currently most distant X-ray detected object. Here we present the detection of significant soft X-ray absorption towards GB 1428+4217, making the absorbing material the most distant matter yet probed with X-ray spectroscopy. X-ray variability by 25+-8 per cent is detected on a timescale of 6500 s in the rest frame. The X-ray variation requires an unusually high radiative efficiency of at least 4.2, further supporting the blazar nature of the source.

description: Just as $^3\roarrow{\rm He}$ can be approximately characterized as a polarized neutron target, polarized \Li6D has been advocated as a good {\em isoscalar} nuclear target for the extraction of the polarized gluon content of the nucleon. The original argument rests upon a presumed ``alpha + deuteron'' picture of \Li6, with the polarization of the nucleus carried by the polarization of the deuteron. We have calculated the polarization of the constituents of \Li6 as a three-body bound state of $α+ n + p$ interacting with local potentials fitted to the scattering data. It is necessary to include partial waves up to $j=17/2$ (75 channels, or, when including the $T=1$ state, 150 channels) in the Faddeev equations before the energy eigenvalue converges. The longitudinal formfactors are then described well by the wave function. Various combinations of $α$N and NN strong and Coulomb potentials yield a straight line in the charge radius {\em vs.} energy plane which, unlike those of previous calculations, passes through the experimental datum. We find for all cases a polarization of the valence neutron in excess of 90\%. This may make polarized \Li6D an attractive target for many nuclear physics purposes, since its neutrons are effectively 45\% polarized.

description: A method to evaluate the particle-phonon coupling (PC) corrections to the single-particle energies in semi-magic nuclei, based on the direct solution of the Dyson equation with PC corrected mass operator, is presented. It is used for finding the odd-even mass difference between even Pb and Sn isotopes and their odd-proton neighbors. The Fayans energy density functional (EDF) DF3-a is used which gives rather highly accurate predictions for these mass differences already at the mean-field level. In the case of the lead chain, account for the PC corrections induced by the low-laying phonons $2^+_1$ and $3^-_1$ makes agreement of the theory with the experimental data significantly better. For the tin chain, the situation is not so definite. In this case, the PC corrections make agreement better in the case of the addition mode but they spoil the agreement for the removal mode. We discuss the reason of such a discrepancy.

description: We present a new many body formalism for BCS-BEC crossover, which represents a modification of the BCS-Leggett ground state to include 4-fermion, and higher correlations. In the BEC regime, we show how our approach contains the \textit{Petrov et al} 4-fermion behavior and associated scattering length $a_{dd}$ at short distances, and secondly reduces to composite-boson Bogoliubov physics at long distances. It reproduces the Lee-Yang term, whose numerical value is also fixed by $a_{dd}$. We have also examined the next term beyond the Lee-Yang correction in a phenomenological fashion, building on cloud size data and collective mode experiments. However, one has to view this phenomenological analysis with some caution since experiments are in a state of flux and are performed close to unitarity.

Sediment transport and the geomorphic evolution of the coastal Trinity River, TX

description: This dissertation uses field observations to understand how changes in sediment transport affect the geomorphic evolution of the coastal Trinity River in Texas. I focus on the main channel of the river along the transition from quasi-uniform flow conditions into gradually varying flow. To begin, I will use elevation data in conjunction with stratigraphic analysis to suggest that scroll bars represent levee deposition along the inner bank of the river channel (Chapter 2). Because their channel-ward edge marks the transition from bed-material transport processes that are associated with the point bar and the proximal overbank deposits of the floodplain, they can be considered the geomorphic edge of the active channel form. Chapters three and four then focus on changes within the active channel through a range of time scales. Separate measurements of inner and outer bank volumetric change and migration show that river banks are capable of migrating independently over short time scales, but migrate compensationally over longer periods. The fifth chapter discusses the observation of a new scale of self-organization in bed topography that occurred along the base of the channel during a historic flood in 2015 (which was captured by the time-lapse lidar used in chapters 3 and 4). Repeat depth surveys show that 12 km long wavelength trains of dunes, spread out over an average of 12 river bends, advected and deformed downstream throughout the 55 day flood. These bedform groups are interpreted as an expression of prolonged washout that occurred over an initially spatially variable bedform field. Remaining questions and suggestions for future research directions are provided in the final chapter. Altogether, this dissertation represents a body of work that spans multiple temporal and spatial scales, and provides the community with a better understanding of how gradually varied flow affects sediment transport and geomorphology. In addition, it provides a foundation for future research that can illuminate important details about fluvial processes in general.
Casimir effect for the scalar field under Robin boundary conditions: A functional integral approach

description: In this work we show how to define the action of a scalar field in a such a way that Robin boundary condition is implemented dynamically, i.e., as a consequence of the stationary action principle. We discuss the quantization of that system via functional integration. Using this formalism, we derive an expression for the Casimir energy of a massless scalar field under Robin boundary conditions on a pair of parallel plates, characterized by constants $c_1$ and $c_2$. Some special cases are discussed; in particular, we show that for some values of $c_1$ and $c_2$ the Casimir energy as a function of the distance between the plates presents a minimum. We also discuss the renormalization at one-loop order of the two-point Green function in the $λϕ^4$ theory submitted to Robin boundary condition on a plate.

Deep and Confident Prediction for Time Series at Uber

description: Reliable uncertainty estimation for time series prediction is critical in many fields, including physics, biology, and manufacturing. At Uber, probabilistic time series forecasting is used for robust prediction of number of trips during special events, driver incentive allocation, as well as real-time anomaly detection across millions of metrics. Classical time series models are often used in conjunction with a probabilistic formulation for uncertainty estimation. However, such models are hard to tune, scale, and add exogenous variables to. Motivated by the recent resurgence of Long Short Term Memory networks, we propose a novel end-to-end Bayesian deep model that provides time series prediction along with uncertainty estimation. We provide detailed experiments of the proposed solution on completed trips data, and successfully apply it to large-scale time series anomaly detection at Uber.

description: Calculations are presented for four relatively strong first-forbidden $β$ decays in the region A=11-16 in order to study the very large mesonic-exchange-current enhancement of the rank-zero components. The $μ^-$ capture on $^{16}$O is considered on the same footing. The wave functions utilized include up to 4$\hbarω$ excitations. Two-body exchange-current matrix elements are calculated as well as one-body impulse approximation matrix elements. The resultant enhancement factor that multiplies the impulse-approximation axial-charge matrix element is thereby determined by comparison to experiment to be $ε_{exp}$ = 1.61 $\pm$ 0.03 from three $β^-$ decays and $μ^-$ capture on $^{16}$O, which is in excellent agreement with meson-exchange calculations in the soft-pion approximation.

Seismic interpretation

description: Picking 3D channel geobodies in seismic volumes is an important objective in seismic interpretation for hydrocarbon exploration. Manual detection of channel geobodies is a time-consuming and subjective process. The interpreter can calculate different seismic attributes such as coherence to aid for manual detection of channel geobodies in seismic volumes. However, these attributes still do not directly identify 3D channel geobodies. Machine learning and deep learning are data-driven techniques that have been getting more attention recently in different fields, such as medical imaging and computer vision. With large volumes of available data in different types and a development of powerful computational resources, geophysics is a promising field for applying machine learning and deep learning. Many seismic interpretation steps are analogous to different problems in computer vision that have been solved successfully using deep learning. Channel detection in seismic volumes is analogous to segmentation problems for images. Applying deep learning to seismic interpretations, specifically to automatic channel detection in 3D seismic volumes, can make the process faster and the workflow less subjective. Decision-making based on interpretations is uncertain; so uncertainties in interpretation results are very important. Deep learning with different algorithms can also help interpreters quantify this uncertainty.

description: Observations of the QSO 0000-2620 with UVES spectrograph at the 8.2m ESO KUEYEN telescope are used for abundance analysis of the damped Ly-alpha system at z_{abs}=3.3901. Several Oxygen lines are identified in the Ly_alpha forest and a measure for the oxygen abundance is obtained at [O/H]=-1.85 +/- 0.1 by means of the unsaturated OI 925 A and OI 950 A lines. This represents the most accurate O measurement in a damped Ly_alpha galaxy so far. We have also detected ZnII 2026 A and CrII 2056, 2062 A redshifted at about 8900 A and found abundances [Zn/H] = -2.07 +/- 0.1 and [Cr/H]=-1.99 +/- 0.1. Furthermore, previous measurements of Fe, Si, Ni and N have been refined yielding [Fe/H]=-2.04 +/- 0.1, [Si/H]=-1.90 +/- 0.1, [Ni/H]=-2.27 +/- 0.1, and [N/H]=-2.68 +/- 0.1. The abundance of the non-refractory element zinc is the lowest among the damped Ly-alpha systems showing that the associated intervening galaxy is indeed in the early stages of its chemical evolution. The fact that the Zn abundance is identical to that of the refractory elements Fe and Cr suggests that dust grains have not formed yet. In this Damped Ly-alpha system the observed [O,S,Si/Zn,Fe,Cr] ratios, in whatever combination are taken, are close to solar (i.e 0.1-0.2 dex) and do not show the [alpha-element/Fe] enhancement observed in Milky Way stars of comparable metallicity. The observed behavior supports a galaxy evolution model characterized by either episodic or low star formation rate rather than a Milky-Way-type evolutionary model.

description: We report the discovery of radio emission from the accreting X-ray pulsar and symbiotic X-ray binary GX 1+4 with the Karl G. Jansky Very Large Array. This is the first radio detection of such a system, wherein a strongly magnetized neutron star accretes from the stellar wind of an M-type giant companion. We measure a $9$ GHz radio flux density of $105.3 \pm 7.3$ $μ$Jy, but cannot place meaningful constraints on the spectral index due to a limited frequency range. We consider several emission mechanisms that could be responsible for the observed radio source. We conclude that the observed properties are consistent with shocks in the interaction of the accretion flow with the magnetosphere, a synchrotron-emitting jet, or a propeller-driven outflow. The stellar wind from the companion is unlikely to be the origin of the radio emission. If the detected radio emission originates from a jet, it would show that that strong magnetic fields ($\geq 10^{12}$ G) do not necessarily suppress jet formation.

description: Peratochetvs limbipennis Rondani, 1863
ORIGINAL DESCRIPTION: 1863: 43.
 TYPE LOCALITY: “ Chiliae [Chile]”.
 TYPE MATERIAL: 1 ♀, syntype (covered with mold) (MZUN: Box Coll. entomol. extra-europea, Gen. Grallomya a Celiphus): Peratochetus limbipennis Rnd., Valdivia / M. Zool. N° 11476.
 CURRENT STATUS: valid species, as Alloclusia limbipennis (Soós 1968: 2); junior synonym of Apiochaeta vitticollis (Blanchard, 1852) (Lonsdale & Marshall 2008: 28).
 REMARKS: Rondani (1863: 43) described Peratochetvs limbipennis, without specifying either the number or the sex of the specimens, but giving a single measurement of length, from material received from R.A. Philippi. Costa (1866: 34) listed a single MZUN specimen numbered “744” from Valdivia [Valdivia (southern Chile)]. Lonsdale & Marshall (2008: 5) incorrectly considered the type of this nominal species, originally deposited in the MZUN, as destroyed. We found one syntype in this study. Rondani described this nominal species under the generic name “ Peratochetvs ”, which is an “incorrect subsequent spelling of Peratochetus Rondani, 1856 ” (O’Hara et al. 2011: 139).

description: We consider the critical temperature in strongly anisotropic antiferromagnetic materials, with weak coupling between stacked planes, in order to determine the interplane coupling constant from experimentally measured susceptibilities. We present theoretical arguments for a universal relation between interplane coupling and susceptibility shown numerically by Yasuda et. al., Phys. Rev. Lett. \textbf{94}, 217201 (2005). We predict a more general scaling function if the system is close to a quantum critical point, a similar relation for other susceptibilities than considered in Yasuda et. al., and the validity of these relations for more general phase transitions.

description: We consider a singularly perturbed parabolic periodic boundary value problem for a reaction-advection-diffusion equation. We construct the interior layer type formal asymptotics and propose a modified procedure to get asymptotic lower and upper solutions. By using sufficiently precise lower and upper solutions, we prove the existence of a periodic solution with an interior layer and estimate the accuracy of its asymptotics. Moreover, we are able to establish the asymptotic stability of this solution with interior layer

description: We review the attempts to construct black hole/string solutions in asymptotically plane wave spacetimes. First, we demonstrate that geometries admitting a covariantly constant null Killing vector cannot admit event horizons, which implies that pp-waves can't describe black holes. However, relaxing the symmetry requirements allows us to generate solutions which do possess regular event horizons while retaining the requisite asymptotic properties. In particular, we present two solution generating techniques and use them to construct asymptotically plane wave black string/brane geometries.

Constraining the exhumation history of high-pressure subduction zone rocks : insights from the Cycladic islands, Greece and the application of novel thermobarometry techniques

description: The mechanisms that lead to exhumation of high-pressure low-temperature (HP-LT) metamorphic rocks have remained enigmatic since the recognition of the petrologic significance of blueschist facies mineral assemblages. Much of our understanding about these mechanisms stems from constraints of the pressure-temperature history of exhumed metamorphic rocks. In this work I describe the results of four projects that focus on testing new thermobarometers that can be applied to metamorphic rocks, among other rock types, and then apply multiple integrative techniques to constrain the pressure-temperature-fluid histories of rocks from Syros and Tinos, Greece. Elastic thermobarometry is a rapidly expanding technique that can be used to constrain pressures and temperatures from inclusion-host mineral pairs. I present a compilation of new inclusion-host mineral pairs that can be used to constrain PT conditions, and an adaptive script that can be used for calculating entrapment pressure or temperature conditions from residual inclusion pressures. I further complete a case-study of the quartz-in-epidote barometer, because of its great abundance in metamorphic rock types and its potential utility for understanding geologic systems that currently lack barometers. Results from heating measurements of quartz inclusions in epidote from Alpine metamorphic rocks indicate two promising conclusions: 1) calculated entrapment pressures show good agreement with previously constrained pressure conditions, indicating that further investigation of the barometer is warranted, and 2) the quartz-in-epidote barometer may not require temperature-dependent entrapment pressure corrections. The Cycladic Blueschist Unit on both Syros and Tinos, Greece, preserves exhumed, HP subduction zone rocks that have an enigmatic history after having reached peak metamorphic conditions. I present a combination of thermobarometry and mineral chemistry techniques that include further application of the quartz-in-epidote barometer, oxygen isotope thermometry, and fluid chemistry as deduced from oxygen, hydrogen, and carbon isotopes, to better understand the protracted exhumation history of metamorphic belts. Results from PT-fluid data from select outcrops that record changing kinematics, indicate that retrograde metamorphic rocks from Syros Greece underwent cooling during decompression, and interaction with slab derived fluids during exhumation. Lower pressure samples from Tinos Greece and hydrogen isotopes possibly show evidence of interaction with meteoric derived fluids during later stages of exhumation along a low-angle detachment.

description: We have used a large format CCD camera to survey the nearby Fornax cluster and its immediate environment for low luminosity low surface brightness galaxies. Recent observations indicate that these are the most dark matter dominated galaxies known and so they are likely to be a good tracer of the dark matter in clusters. We have identified large numbers of these galaxies consistent with a steep faint end slope of the luminosity function (alpha~ -2) down to MB ~ -12. These galaxies contribute almost the same amount to the total cluster light as the brighter galaxies and they have a spatial extent that is some four times larger. They satisfy two of the important predictions of N-body hierarchical simulations of structure formation using dark halos. The luminosity (mass ?) function is steep and the mass distribution is more extended than that defined by the brighter galaxies. We also find a large concentration of low surface brightness galaxies around the nearby galaxy NGC1291.

description: This paper deals with the computation of regular coderivatives of solution maps associated with a frequently arising class of generalized equations. The constraint sets are given by (not necessarily convex) inequalities, and we do not assume linear independence of gradients to active constraints. The achieved results enable us to state several versions of sharp necessary optimality conditions in optimization problems with equilibria governed by such generalized equations. The advantages are illustrated by means of examples.
The maximum density droplet to lower density droplet transition in quantum dots

description: We show that, Landau level mixing in two-dimensional quantum dot wave functions can be taken into account very effectively by multiplying the exact lowest Landau level wave functions by a Jastrow factor which is optimized by variance minimization. The comparison between exact diagonalization and fixed phase diffusion Monte Carlo results suggests that the phase of the many-body wave functions are not affected much by Landau level mixing. We apply these wave functions to study the transition from the maximum density droplet state (incipient integer quantum Hall state with angular momentum L=N(N-1)/2) to lower density droplet states (L>N(N-1)/2).
