description: A quantitative study of the Luminous Blue Variable NGC 2363-V1 in the Magellanic galaxy NGC 2366 (D = 3.44 Mpc) is presented, based on ultraviolet and optical HST/STIS spectroscopy. Contemporary WFPC2 and WHT imaging reveals a modest V-band brightness increase of ~ 0.2 mag per year between 1996 January and 1997 November, reaching V=17.4 mag, corresponding to Mv=-10.4 mag. Subsequently, V1 underwent a similar decrease in V-band brightness, together with a UV brightening of 0.35 mag from 1997 November to 1999 November. The optical spectrum of V1 is dominated by H emission lines, with Fe II, He I and Na I also detected. In the ultraviolet, a forest of Fe absorption features and numerous absorption lines typical of mid-B supergiants are observed. From a spectral analysis with the non-LTE, line-blanketed code of Hillier & Miller (1998), we derive stellar parameters of T*=11kK, R*=420Ro, log(L/Lo)=6.35 during 1997 November, and T*=13kK, R*=315Ro, log(L/Lo)=6.4 for 1999 July. The wind properties of V1 are also exceptional, with Mdot ~ 4.4 x 10e-4 Mo/yr and $v_{\infty} ~ $300 km/s, allowing for a clumped wind (filling factor = 0.3), and assuming H/He ~ 4 by number. The presence of Fe lines in the UV and optical spectrum of V1 permits an estimate of the heavy elemental abundance of NGC 2363 from our spectral synthesis. Although some deficiencies remain, allowance for charge exchange reactions in our calculations supports a SMC-like metallicity, that has previously been determined for NGC 2363 from nebular oxygen diagnostics. Considering a variety of possible progenitor stars, V1 has definitely undergone a giant eruption, with a substantial increase in stellar luminosity, radius, and almost certainly mass-loss rate.

description: Many factors contribute to assessing the technical viability of isolating chemical waste in solution-mined caverns within salt domes. Our investigation highlights several key factors of primary importance, including geohydrology, engineering considerations, and the stability of the geologic isolation system, encompassing the cavern, cap rock, and surrounding strata. These factors are largely interconnected and mutually dependent. An essential initial step involves detailed mapping of the domal system, including the cap rock, salt stock, and surrounding domed strata, a level of detail often lacking in public sources and geological literature. Postulated release scenarios typically involve waste transport via groundwater, making the direction and rates of groundwater flow critical. Groundwater flow is influenced by various factors such as rock matrix composition, depositional systems, sand-body geometry, and fault patterns. The cap rock serves as a focal point for many domal processes and is a dynamically changing region of a salt dome. Studies on cap-rock properties can help determine whether salt domes are undergoing uplift or dissolution. The cap rock plays a crucial role in either facilitating or impeding dome dissolution and cavern stability. Further research on salt domes should focus on defining the geometry and structure of cap rocks, identifying cap-rock lost-circulation zones, understanding the geometry, structure, and stratigraphy of salt stocks and caverns, assessing salt-cavern stability, and investigating domal geohydrology. In the following sections, we discuss various issues that need to be addressed to evaluate the technical feasibility of isolating chemical waste in solution-mined caverns within salt domes.

description: The Type II Superstring amplitude to 1-loop order is given by an integral of $\vartheta$-functions over the moduli space of tori, which diverges for real momenta. We construct the analytic continuation which renders this amplitude well defined and finite, and we find the expected poles and cuts in the complex momentum plane.

description: Context. Transit events of extrasolar planets offer the opportunity to study the composition of their atmospheres. Previous work on transmission spectroscopy of the close-in gas giant TrES-3 b revealed an increase in absorption towards blue wavelengths of very large amplitude in terms of atmospheric pressure scale heights, too large to be explained by Rayleigh-scattering in the planetary atmosphere. Aims. We present a follow-up study of the optical transmission spectrum of the hot Jupiter TrES-3 b to investigate the strong increase in opacity towards short wavelengths found by a previous study. Furthermore, we aim to estimate the effect of stellar spots on the transmission spectrum. Methods. This work uses previously published long slit spectroscopy transit data of the Gran Telescopio Canarias (GTC) and published broad band observations as well as new observations in different bands from the near-UV to the near-IR, for a homogeneous transit light curve analysis. Additionally, a long-term photometric monitoring of the TrES-3 host star was performed. Results. Our newly analysed GTC spectroscopic transit observations show a slope of much lower amplitude than previous studies. We conclude from our results the previously reported increasing signal towards short wavelengths is not intrinsic to the TrES-3 system. Furthermore, the broad band spectrum favours a flat spectrum. Long-term photometric monitoring rules out a significant modification of the transmission spectrum by unocculted star spots.

Quantum point contacts were used to detect charge fluctuations. A clear reduction of both short time scale telegraphic noise and long time scale conductance drift with decreased doping density was observed. These measurements indicate that the {\it neutral} doping region plays a significant role in charge noise and conductance drift.

description: A cross-sectional ground-water flow model was constructed of the Palo Duro Basin to analyze available hydrogeologic data and better understand the causes of underpressuring below the Evaporite Aquitard and mechanisms of recharge and discharge to and from the Deep-Basin Brine Aquifer. Various effects of lithostratigraphy and topography on subhydrostatic conditions in the deep section were investigated in different simulations. The model indicates that the subhydrostatic pressures beneath the Evaporite Aquitard are caused by segregation of deep and shallow flow systems by the low-permeable evaporite section and drainage of the deep system by relatively permeable granite wash deposits. The Pecos River, which allows underflow of some groundwater recharging in the New Mexico area to the west, enhances underpressuring beneath the western half of the High Plains by serving as a discharge area for water that would otherwise move downdip into the Deep-Basin Brine Aquifer. In addition to this recharge, about 26% of the groundwater in the Deep-Basin Brine Aquifer originates from leakage through the evaporite section, assuming K2 = 2.8 x 10-4 md, the upper limit of aquitard permeability suggested by the model. The groundwater flow pattern within the Deep-Basin Brine Aquifer is governed by the spatial distribution of more permeable strata, particularly the granite wash deposits. In the cross-sectional model, most of the groundwater in the Deep-Basin Brine Aquifer discharges laterally through the eastern boundary and eventually by upward leakage in the easternmost part of the cross-section. Ground-water travel times through the Deep-Basin Brine Aquifer from the westernmost recharge area in New Mexico to the eastern boundary of the model range between 1.2 and 4 million years, depending on the flow path depicted by the streamtubes and average porosities of the different units.

description: Markov Chain Monte Carlo (MCMC) methods for sampling probability density functions (combined with abundant computational resources) have transformed the sciences, especially in performing probabilistic inferences, or fitting models to data. In this primarily pedagogical contribution, we give a brief overview of the most basic MCMC method and some practical advice for the use of MCMC in real inference problems. We give advice on method choice, tuning for performance, methods for initialization, tests of convergence, troubleshooting, and use of the chain output to produce or report parameter estimates with associated uncertainties. We argue that autocorrelation time is the most important test for convergence, as it directly connects to the uncertainty on the sampling estimate of any quantity of interest. We emphasize that sampling is a method for doing integrals; this guides our thinking about how MCMC output is best used.

description: Microscopic black holes explode with their temperature varying inversely as their mass. Such explosions would lead to the highest temperatures in the present universe, all the way to the Planck energy. Whether or not a quasi-stationary shell of matter undergoing radial hydrodynamic expansion surrounds such black holes is been controversial. In this paper relativistic viscous fluid equations are applied to the problem. It is shown that a self-consistent picture emerges of a fluid just marginally kept in local thermal equilibrium; viscosity is a crucial element of the dynamics.

description: Looking out of Information Science (IS) it´s a dangerous attempt to compare this relative new science direct with Philosophy. Here you find a first circumspective trial of an investigation of the traditionally named “queen of science”, Philosophy, two thousand years old and - direct opposite - the only a half century old Information Science. For me it is till now not yet clear how to do this in a serious scientific manner. I worked in Applied Informatics for 30 years and make Information Science since about 15 years. Here I dare to publish for first time the results. SOKRATES (469 – 399 b.Chr.), PLATON (428/27- 348/47 b.Chr.) und ARISTOTELES (384 - 322 b.Chr.) as inventors of our traditional occidental Philosophy, have founded the search of the sense of our Human Life, Thinking and Acting as an own science. They set the Joy of Life on top of their way of thinking. PLATON has separated this special new thinking from the „Sophists“ who had a very good public image too at his time. But they were thinking more about common business facts and knowledge only. Today we would call them manufacturer, qualified skilled workers or even bachelors of special sciences.

Philosophy has (since over 20 centuries) till today first of all the smart and high duty to serve Religion and Ethics as mental, spirit- and language-grounded science-base. In other direction it was used to overthink our whole surrounding nature theoretically and completely by our best Human Mind. It´s our traditional science on our mental highest level. All sciences can be related by Philosophy. That´s possible by our human ability to Learn, Think, Understand and finally Know any interesting new fact.

Where and how do we have now to integrate this new own science Information Science? We search consciously term-oriented and make an abstract science-theoretical comparison to find answers and definitions.

description: Information on permeability and porosity of the Deep-Basin Brine Aquifer is important for describing flow pattern and flow velocity of deep-basinal fluids. Permeabilities were estimated from drill-stem tests, pumping tests, and published values of equivalent geologic materials. In addition, permeabilities and porosities of different lithologies were determined from laboratory tests of cores. The objectives of core analysis are: 1. Determine porosities and permeabilities of the different geologic lithofacies. 2. Relate porosities to petrographic description of pore types and lithology. 3. Obtain vertical and horizontal distribution of porosity and permeability from the analyzed core intervals. 4. Compare core permeabilities to drill-stem test and pumping test analyses. 5. Compare core-derived porosity values with porosities from neutron-density cross plots.

Mining the Metal-Rich Stars for Planets
Creators: name: Laughlin, Gregory
Publisher: name: arXiv
Year: 2000
Subjects: subject: Astrophysics (astro-ph)
subject: FOS: Physical sciences

description: We examine the correlation between stellar metallicity and short period planets. It appears that approximately 1% of dwarf stars in the solar neighborhood harbor short-period planets characterized by near-circular orbits and orbital periods P<20 days. However, among the most metal-rich stars (defined as having [Fe/H]>0.2 dex), it appears that the fraction increases to 10%. Using the Hipparcos database and the Hauck & Mermilliod (1998) compilation of Stromgren uvby photometry, we identify a sample of 206 metal-rich stars of spectral type K, G, and F which have an enhanced probability of harboring short-period planets. Many of these stars would be excellent candidates for addition to radial velocity surveys. We have searched the Hipparcos epoch photometry for transiting planets within our 206 star catalog. We find that the quality of the Hipparcos data is not high enough to permit unambiguous transit detections. It is, however, possible to identify candidate transit periods. We then discuss various ramifications of the stellar metallicity - planet connection. First, we show that there is preliminary evidence for increasing metallicity with increasing stellar mass among known planet-bearing stars. This trend can be explained by a scenario in which planet-bearing stars accrete an average of 30 Earth Masses of rocky material after the gaseous protoplanetary disk phase has ended. We present dynamical calculation which suggest that a survey of metallicities of spectroscopic binary stars can be used to understand the root cause of the stellar metallicity - planet connection.

title: Hydrodynamic Development of the Palo Duro Basin and Other Mechanisms Creating Possible Transient Flow Conditions
Creators: name: Senger, Rainer K.
Publisher: name: The University of Texas at Austin
Year: 1984
Subjects: subject: groundwater
subject: hydrodynamics
subject: Texas Panhandle
subject: Palo Duro Basin

description: Characterization of the regional flow regime in the Palo Duro Basin is assisted by numerical groundwater flow models as described by INTERA (1984), Senger and Fogg (1984), and Wirojanagud and others (1984). In general, the models which incorporate the available hydrogeologic information simulate hydraulic head distribution and fluxes under steady-state conditions. The computed heads are then compared to measured heads in order to evaluate the adequacy of the conceptual model. The conceptualized flow regime in the Palo Duro Basin is generally assumed to represent a steady-state, gravity-driven flow system of the type described by Hubbert (1940). Groundwater flow is governed by the fluid potential along the topographic surface and permeability of the hydrostratigraphic units. In the Palo Duro Basin, extensive modification of the topography as a result of tectonic and geomorphologic processes has occurred within the last 15 million years (McGookey, 1984; Gustavson and others, 1981). Accordingly, it is possible that hydraulic heads observed in the Deep-Basin Brine aquifer represent transient conditions and that they are still equilibrating to modifications of topography in the past. Significant hydrocarbon occurrences in the Texas Panhandle suggest other possible mechanisms creating transient flow conditions as a result of reservoir pressure decline due to hydrocarbon production. The purpose of this study is to investigate transient flow conditions and to identify possible flow patterns resulting from changing hydrologic conditions with time. For this purpose, the model herein is used to simulate possible groundwater flow patterns caused by different tectonic and geomorphologic processes. The hydrodynamic development of the basin is crucial to the origin and hydrochemical evolution of the fluid in the deep basin. Changing hydraulic head distributions with time result in changes of groundwater flow paths. Consequently, transport of chemical constituents could have traveled along ancient pathways much different than is suggested by the present-day hydraulic head distribution observed in the basin.

description: We examine the problem of defining Lagrangian and Hamiltonian mechanics for a particle moving on a quantum plane $Q_{q,p}$. For Lagrangian mechanics, we first define a tangent quantum plane $TQ_{q,p}$ spanned by noncommuting particle coordinates and velocities. Using techniques similar to those of Wess and Zumino, we construct two different differential calculi on $TQ_{q,p}$. These two differential calculi can in principle give rise to two different particle dynamics, starting from a single Lagrangian. For Hamiltonian mechanics, we define a phase space $T^*Q_{q,p}$ spanned by noncommuting particle coordinates and momenta. The commutation relations for the momenta can be determined only after knowing their functional dependence on coordinates and velocities. Thus these commutation relations, as well as the differential calculus on $T^*Q_{q,p}$, depend on the initial choice of Lagrangian. We obtain the deformed Hamilton's equations of motion and the deformed Poisson brackets, and their definitions also depend on our initial choice of Lagrangian. We illustrate these ideas for two sample Lagrangians. The first system we examine corresponds to that of a nonrelativistic particle in a scalar potential. The other Lagrangian we consider is first order in time derivatives

description: Stratigraphic studies of the Palo Duro Basin are now in their 8th year. Although the emphasis in these studies now lies in the San Andres Formation (possible repository host rock) and the Wolfcamp Series (sub-repository aquifer), investigations of other units (fig. 1) continue to be carried out as well. This report includes work that was not available for inclusion in last year's (1983) CSR on stratigraphy (Open File Report No. OF-WTWI-1984-30). The section on pre-Pennsylvanian stratigraphy represents the final stages of study of those units. The report detailing structural controls on deposition of the San Andres is part of an ongoing effort to recognize indications of structural or tectonic controls on sedimentation throughout the stratigraphic column in the Palo Duro Basin area. Studies of the Dockum Group are revealing similar controls during the Triassic. Core studies of the Dockum are increasing our resolution of depositional settings in the area.

description: We propose a lattice field theory formulation which overcomes some fundamental difficulties in realizing exact supersymmetry on the lattice. The Leibniz rule for the difference operator can be recovered by defining a new product on the lattice, the star product, and the chiral fermion species doublers degrees of freedom can be avoided consistently. This framework is general enough to formulate non-supersymmetric lattice field theory without chiral fermion problem. This lattice formulation has a nonlocal nature and is essentially equivalent to the corresponding continuum theory. We can show that the locality of the star product is recovered exponentially in the continuum limit. Possible regularization procedures are proposed.The associativity of the product and the lattice translational invariance of the formulation will be discussed.

description: Magnetoimpedance, MI, change due to surface modification of the sensitive element caused by biofluids was studied with the aim of creating a robust sensor capable of separating the chemical surface modification from the sensing process. A MI sensor prototype with an as-quenched FeCoSiB amorphous ribbon sensitive element was designed and calibrated for a frequency range of 0.5 to 10 MHz at an intensity of the current of 60 mA. Measurements as a function of the exposure time were made, first, in a regime where chemical surface modification and sensing were separated and then, in a regime where they were not separated (in a bath for fluids). The MI variation was explained by the change of the surface magnetic anisotropy. It was shown that the magnetoimpedance effect can be successfully employed as a new electrochemical option to probe the electric features of surface-modified magnetic electrodes when the biofluid, the material of the sensitive element, and the detection conditions are properly selected and synergetically adjusted.

description: Since the beginning of Bureau research into the Palo Duro Basin area in 1979, more than 150 geologic reports have been completed and published. Approximately 30 are currently in press. Because of continuing research in the area, however, a great deal of additional work still remains unpublished. This report provides an update on ongoing, as yet unpublished research into the stratigraphy of the Palo Duro Basin (fig. 1). Although investigations on some scale are being carried out on essentially all of the stratigraphic horizons in the Palo Duro Basin area (fig. 2), only those units which have recently been the focus of relatively concentrated research efforts are reported herein. This necessarily includes those units being analyzed for hydrocarbon potential (Mississippian and Pennsylvanian Systems), those that are the focus of hydrologic studies (Permian Wolfcamp Series and Permo-Triassic Dockum Group and Dewey Lake Formation), and the proposed waste repository horizon (Permian San Andres Formation). Work on other stratigraphic units is of lower priority and is being carried out peripherally. Table 1 indicates researchers responsible for contributions to this report and those who are continuing to study various stratigraphic units in the area.

description: The sum of ratios problem has a variety of important applications in economics and management science, but it is difficult to globally solve this problem. In this paper, we consider the minimization problem of a sum of a number of nondifferentiable quasi-convex component functions over a closed and convex set, which includes the sum of ratios problem as a special case. The sum of quasi-convex component functions is not necessarily to be quasi-convex, and so, this study goes beyond quasi-convex optimization. Exploiting the structure of the sum-minimization problem, we propose a new incremental subgradient method for this problem and investigate its convergence properties to a global optimal solution when using the constant, diminishing or dynamic stepsize rules and under a homogeneous assumption and the Hölder condition of order $p$. To economize on the computation cost of subgradients of a large number of component functions, we further propose a randomized incremental subgradient method, in which only one component function is randomly selected to construct the subgradient direction at each iteration. The convergence properties are obtained in terms of function values and distances of iterates from the optimal solution set with probability 1. The proposed incremental subgradient methods are applied to solve the sum of ratios problem, as well as the multiple Cobb-Douglas productions efficiency problem, and the numerical results show that the proposed methods are efficient for solving the large sum of ratios problem.

description: Investigations of the petroleum potential of the Palo Duro Basin have been underway since 1978. This report contains the results of studies carried out during the 1983-84 fiscal year, which have not yet been published. The section of this report dealing with pre-Pennsylvanian units in the basin represents the final results of work done on these rocks. Work is continuing on Pennsylvanian and younger strata as further data become available. The second part of this report presents additional data recently gathered on these units.
The Relation between Quantum W algebras and Lie algebras

description: By quantizing the generalized Drinfeld-Sokolov reduction scheme for arbitrary $sl_2$ embeddings we show that a large set $\cal W$ of quantum W algebras can be viewed as (BRST) cohomologies of affine Lie algebras. The set $\cal W$ contains many known $W$ algebras such as $W_N$ and $W_3^{(2)}$. Our formalism yields a completely algorithmic method for calculating the W algebra generators and their operator product expansions, replacing the cumbersome construction of W algebras as commutants of screening operators. By generalizing and quantizing the Miura transformation we show that any $W$ algebra in $\cal W$ can be embedded into the universal enveloping algebra of a semisimple affine Lie algebra which is, up to shifts in level, isomorphic to a subalgebra of the original affine algebra. Therefore {\em any} realization of this semisimple affine Lie algebra leads to a realization of the $W$ algebra. In particular, one obtains in this way a general and explicit method for constructing the free field realizations and Fock resolutions for all algebras in $\cal W$. Some examples are explicitly worked out.

description: Numerous wells produce warm groundwater from several Cretaceous aquifers located beneath the innermost part of the Texas Gulf Coastal Plain. The changes in landscape between the Coastal Plain and the uplands farther west result from a major geologic break. Texas is bisected along this trend by the Texas Craton, a hinge zone that separates the downwarping Gulf Coast Basin from the more stable continental interior. At depth, this hinge is defined by the subsided Ouachita Mountains; at the surface, the geologic break is expressed by the Balcones and Luling-Mexia-Talco Fault Zones. The geologic hinge zone has clearly affected the physiography of the region. These effects include abrupt changes in terrain, climate, soils, vegetation, and availability of groundwater across the hinge. These changes have, in turn, influenced human settlement patterns (Bybee, 1952). The Balcones/Ouachita hinge is a geocultural break similar in cause and comparable in effect to the Fall Line of the Eastern United States (Woodruff, 1980). Both trends are the loci of cities. The towns and cities along the Balcones/Ouachita trend might use the thermal resources; at some localities, the warm water is already used although as drinking water and not generally for its energy content. Studies at the Bureau of Economic Geology have documented geothermal waters in many places across Texas (Henry, 1979; Henry and Gluck, 1981; Woodruff and others, 1982). Locally, these waters may be hotter or more abundant than along the Balcones/Ouachita trend, but considering both geologic and socioeconomic aspects, Central Texas is probably the region with the greatest potential for developing a cost-effective energy resource from low-temperature geothermal waters. The cities along the Balcones/Ouachita trend constitute a market for the geothermal energy resource.

description: We report on experiments on an evanescent-wave mirror for cold $^{87}$Rb atoms. Measurements of the bouncing fraction show the importance of the Van der Waals attraction to the surface. We have directly observed radiation pressure parallel to the surface, exerted on the atoms by the evanescent-wave mirror. We analyze the radiation pressure by imaging the motion of the atom cloud after the bounce. The number of photon recoils ranges from 2 to 31. This is independent of laser power, inversely proportional to the detuning and proportional to the evanescent-wave decay length. By operating the mirror on an open transition, we have also observed atoms that bounce inelastically due to a spontaneous Raman transition. The observed distributions consist of a dense peak at the minimum velocity and a long tail of faster atoms, showing that the transition is a stochastic process with a strong preference to occur near the turning point of the bounce.

description: The security of conventional cryptography systems is threatened in the forthcoming era of quantum computers. Quantum key distribution (QKD) features fundamentally proven security and offers a promising option for quantum-proof cryptography solution. Although prototype QKD systems over optical fiber have been demonstrated over the years, the key generation rates remain several orders-of-magnitude lower than current classical communication systems. In an effort towards a commercially viable QKD system with improved key generation rates, we developed a discrete-variable QKD system based on time-bin quantum photonic states that is capable of generating provably-secure cryptographic keys at megabit-per-second (Mbps) rates over metropolitan distances. We use high-dimensional quantum states that transmit more than one secret bit per received photon, alleviating detector saturation effects in the superconducting nanowire single-photon detectors (SNSPDs) employed in our system that feature very high detection efficiency (of over 70%) and low timing jitter (of less than 40 ps). Our system is constructed using commercial off-the-shelf components, and the adopted protocol can readily be extended to free-space quantum channels. The security analysis adopted to distill the keys ensures that the demonstrated protocol is robust against coherent attacks, finite-size effects, and a broad class of experimental imperfections identified in our system.

description: Scanning tunneling spectroscopy measurements on thin epitaxial SrRuO3/(100)YBCO ferromagnet/superconductor bilayers, reveal localized regions in which the superconductor order parameter penetrates the ferromagnet to more than 26 nm, an order of magnitude larger than the coherence length in the ferromagnetic layer. These regions consist of narrow (< 10 nm) and long strips, separated by at least 200 nm, consistent with the known magnetic domain wall structure in SrRuO3. We attributed this behavior to Crossed Andreev Reflections, taking place in the vicinity of the magnetic domain walls.
