description: We establish an analogy between superconductor-metal interfaces and the quantum physics of a black hole, using the proximity effect. We show that the metal-superconductor interface can be thought of as an event horizon and Andreev reflection from the interface is analogous to the Hawking radiation in black holes. We describe quantum information transfer in Andreev reflection with a final state projection model similar to the Horowitz-Maldacena model for black hole evaporation. We also propose the Andreev reflection-analogue of Hayden and Preskill's description of a black hole final state, where the black hole is described as an information mirror. The analogy between Crossed Andreev Reflections and Einstein-Rosen bridges is discussed: our proposal gives a precise mechanism for the apparent loss of quantum information in a black hole by the process of nonlocal Andreev reflection, transferring the quantum information through a wormhole and into another universe. Given these established connections, we conjecture that the final quantum state of a black hole is exactly the same as the ground state wavefunction of the superconductor/superfluid in the Bardeen-Cooper-Schrieffer (BCS) theory of superconductivity; in particular, the infalling matter and the infalling Hawking quanta, described in the Horowitz-Maldacena model, forms a Cooper pair-like singlet state inside the black hole. A black hole evaporating and shrinking in size can be thought of as the analogue of Andreev reflection by a hole where the superconductor loses a Cooper pair. Our model does not suffer from the black hole information problem since Andreev reflection is unitary. We also relate the thermodynamic properties of a black hole to that of a superconductor, and propose an experiment which can demonstrate the negative specific heat feature of black holes in a growing/evaporating condensate.

description: The results of a 700 arcmin^2 survey for EROs are presented. The sky distribution of EROs is very inhomogeneous and their two point correlation function shows a very high amplitude, a factor of 10 larger than that of the field galaxy population. Such a clustering can explain the strong variance found in previous works, and provides evidence that ERO are mostly made of high-z ellipticals. The surface density of EROs found in our large survey is in good agreement with that expected for passively evolving ellipticals formed at high redshift (z\simgt2.5).

description: Previous assessments of blanket-geometry tight gas sandstones led to the selection of the Travis Peak Formation of the East Texas and North Louisiana Basins and the Corcoran and Cozzette Sandstones of the Piceance Creek Basin as major research objectives. The anticipated outcomes of this study include increased availability of tight gas resources and advancements in technology with high transferability. The work reported here encompasses all aspects of the depositional systems and reservoir geology of these units as fundamental components of resource characterization, with an emphasis on understanding controls on reservoir facies distribution and their relevance to low-permeability reservoir development. Six lithofacies of the Travis Peak (Hosston) Formation in East Texas and North Louisiana have been identified using electric logs. These facies comprise sand-rich fluvial-deltaic, silt-rich delta-front, clay- and carbonate-rich shelf, carbonate reef, and clay-rich open marine facies. The most well-developed facies in the East Texas area are the fluvial-deltaic and delta-front facies. Travis Peak rocks from the Clayton Williams #11 Sam Hughes well, Panola County, Texas, were primarily deposited in a fluvial environment within a coastal plain setting. Porosity and permeability control in the clean sandstones are primarily attributed to quartz overgrowths, chlorite cement, and solid organic matter, with approximately half of the remaining porosity being secondary, resulting from framework grain dissolution. Studies of Travis Peak gas production at Pinehill Southeast and Percy-Wheeler fields indicate an average permeability-thickness product of about 10 md-ft, with a range of 0.7 to 35 md-ft, indicating dry gas reservoirs. Well logs, core, and mud logs from Chapel Hill field in Smith County, Texas, were examined in preparation for a complete cooperative well program in the ARCO #11 Phillips well on the western margin of that field. Field studies of Corcoran-Cozzette Sandstones near Grand Junction, Colorado, suggest that the depositional environments of the Corcoran evolved from marine upper shoreface to non-marine, while the Cozzette sequence evolved from lower to upper shoreface. Porosity and water saturation calculations have been conducted by computer for seven Corcoran and Cozzette depositional units. A comparison of calculated water saturation with core-derived porosity and permeability indicates a fair to very good correlation of reservoir properties with clay content measured by gamma-ray log.

description: This is the final report to be submitted to the Department of Energy under the Consolidated Geothermal contract (DE-AC08-79ET21208) with the Bureau of Economic Geology. The report contains two sections. Section I presents the conclusions of work under the "Resource Assessment and Seismic Studies" project topic. It ties together the prospect and study areas described previously with a regional statistical survey of fault compartments. Section II reports the conclusions of the "Synthesis of Data" project topic. New vitrinite reflectance and hydrocarbon data are combined with previous information to yield a revised theory of fluid migration and temperature history in the vicinity of the Pleasant Bayou test-well site. In addition, the project topic of "Environmental Monitoring" has been concluded, under separate subcontractors' reports. Seismic monitoring under subcontract to Teledyne Geotech was completed, and a final report was submitted (Mauk and others, 1984). A variety of significant events were detected, but it is difficult to assign causes to them. At the request of the U.S. Department of Energy, the Bureau subcontracted with the Meyer Group to conduct a first-order releveling of the Pleasant Bayou site to update and replace the 1978 baseline study. The work was performed in the summer of 1984, and a final report prepared in October 1984 was transmitted to the Bureau of Economic Geology and then to the U.S. Department of Energy (Meyer Group, 1984). Interpretation of the results of this study is funded under the current geopressured geothermal research contract, along with new studies of environmental effects such as modeling of subsidence and fault reactivation, and production of liquid hydrocarbons from the geothermal test wells. All other topics of the expired contract, including Sandstone Consolidation, salinity, and Reservoir Continuity, have been fully documented in previous annual reports (Morton and others, 1983; Ewing and others, 1984), as well as Bureau and outside publications.

description: A unified theory of the anomalous Hall effect (AHE) is presented for multi-band ferromagnetic metallic systems with dilute impurities. In the clean limit, the AHE is mostly due to the extrinsic skew-scattering. When the Fermi level is located around anti-crossing of band dispersions split by spin-orbit interaction, the intrinsic AHE to be calculated ab initio is resonantly enhanced by its non-perturbative nature, revealing the extrinsic-to-intrinsic crossover which occurs when the relaxation rate is comparable to the spin-orbit interaction energy.

description: Discharge of heavy metal laden wastewaters into the aquatic environment continues to inspire research into the development of low-cost treatment technologies. The identification of low-cost biosorbents and their subsequent optimization particularly through surface modification has been reported to improve the efficiency of biosorption process. This study investigates the biosorptive performance of treated and untreated forest macro-fungus Fomes fasciatus for the uptake of Cu (II) ions (a model cation) from aqueous solution. Batch equilibrium experiments at room temperature were conducted to assess removal as a function of solution concentration and biosorbent mass. An improvement of 17.5 per cent increase in sorption capacity as well as an accompanying increase in affinity was observed as a result of hot-alkali treatment of the biosorbent. Primary equilibrium data was analyzed by linear and non-linear regression using the Langmuir and Freundlich two-parameter models as well as the Redlich-Peterson and Sips three- parameter models. The goodness of fit was assessed using the coefficient of determination, r2, the Relative Percent Error, RPE, Marquardt’s Percent Standard Deviation, MPSD and Hybrid Error Function, HYBRID. The two-parameter Langmuir model exhibited a high correlation to the experimental data and was successful in providing some insight into the biosorptive process. The three-parameter models produced the highest correlation to the equilibrium data, sufficient to enable the future development of predictive models.

description: Since the spatially extended periodic parity-time (PT) symmetric potential can possess certain unique properties compared to a single PT cell (with only a pair of coupled gain-loss components), various schemes have been proposed to realize periodic PT-symmetric potentials based on optical lattices. Here, we experimentally construct a spatially periodic PT-symmetric optical potential based on gain-loss arrays induced in a coherently-prepared atomic medium. The gain and loss arrays are generated in alternating four-level N-type and three-level $Λ$-type configurations in the same atomic medium, respectively, which do not require discrete diffractions as demonstrated in the previous work [Phys. Rev. Lett. 117, 123601(2016)] and can be easier to realize with more relaxed operating conditions. The dynamical behaviors of the system are investigated by measuring the phase difference between two adjacent gain and loss channels. The demonstrated PT-symmetric optical lattice with easy accessibility and better tunability sets a new stage for further exploiting the peculiar physical properties in periodic non-Hermitian systems.

description: Metsälaitumet tarjoavat eläimille monia hyötyjä, kuten suojan talvella ja varjoa kesällä. Lisäksi ne tarjoavat rapsutuspuita karvan kunnon ylläpitoon. Kotieläinten käyttäytyminen voidaan jakaa seuraaviin ryhmiin: liikkuminen, syöminen, lisääntyminen, sosiaalinen käytös, lepo ja jälkikasvun hoitaminen. Pääsy puiden luo voi jollain tavoin hyödyttää kaikkia näitä käytöksiä. Suuri osa eläinten päivittäisestä käytöksestä liittyy tasapainotilan, eli homeostasian, ylläpitoon: eläin esimerkiksi etsii ja syö ruokaa ollessaan nälkäinen. Samalla tavoin ollessaan kuumissaan tai kylmissään se etsii varjoa tai suojaa, ja puut, pensaat ja suojaistutukset voivat tarjota sille suojaa tehokkaasti. Karvan kunto on tärkeä eläimen hyvinvoinnin kannalta, ja eläimet käyttävät puiden runkoja ja oksia mielellään rapsutuspuina. Eläinten vastasyntynyt jälkikasvu joko piiloutuu (esim. vasikat) tai seuraa laumaa (esim. karitsat), mutta kaikkien lajien emot etsivät suojaa synnyttäessään. - AFINET Factsheet exploring the benefits of silvopasture to domestic animals. The benefits of silvopasture to domestic animals include access to shelter in the winter and shade in the summer, as well as providing scratching posts to maintain coat condition. The behaviour of domestic animals can be grouped into the categories of locomotion, maternal, nutritional, reproductive, social and resting behaviours and access to trees can be of some benefit to them all.
Sacrifice as a Narrative Strategy: The Construction and Destruction of the Self in May Sinclair, Mary Butts, and H. D.
Creators: name: Melin Schyllert, Kimberly
Publisher: name: University of Westminster
Year: 2017

description: This thesis investigates sacrifice in experimental narratives of the early twentieth century by May Sinclair, Mary Butts, and H. D. (Hilda Doolittle). I argue that sacrifice is used as a narrative strategy for negotiating the relationship between self and other, not only on a thematic level, but also in terms of narrative strategy. These shifts are not only indicative of the tendency to experiment with unexpected narrative strategies in early twentieth century fiction, but also reveal a concern with the individual self in relation to a community of other selves that intersects several wider issues in the historical/cultural context of the works studied: the First World War, first-wave feminism, psychoanalysis, and anthropological research. As first-,
second-, and third-person modes of narration are interspersed, the boundaries between narrative selves are continually dissolved and reinstated. The continuous
negotiation of the boundaries of the narrative voice means that these narratives promote both the death and the resurrection of the subjective self through the use of sacrifice as a narrative strategy.

Imagination is quantified too and in no-exam situations. Hybrid professions emerge in self-organization of non-hierarchical collaborations among independent professionals. The connections between independent professionals, and between independent professionals and collaborations are meaningful and unique for them. Deeper and automated thinking are being visualized from humor appreciation by the user. Every user owns their own data and decides over it. Shared vision has the last say, because the connections are made in blindness to any socio-political and facial data, confused too often with competence. IIB is opposite to all those networks which promote statuses, anchoring, visual impressions, and hype, in superficial or no truly compatible connections. IIB empowers problem-solvers and focuses their attention on their goals and visions. IIB online: https://intellectualandimmaterialbank.com/ Wise Jester: https://www.wisejester.org/

description: We have studied the variability of the black-widow type binary millisecond pulsar PSR J1311$-$3430 from optical to gamma-ray energies. We confirm evidence for orbital modulation in the weak off-pulse $\ge$200-MeV emission, with a peak at $ϕ_B\approx 0.8$, following pulsar inferior conjunction. The peak has a relatively hard spectrum, extending above $\sim 1$\,GeV. XMM-Newton and Swift UV observations also show that this source's strong X-ray flaring activity is associated with optical/UV flares. With a duty cycle $\sim 7-19$%, this flaring is quite prominent with an apparent power-law intensity distribution. Flares are present at all orbital phases, with a slight preference for $ϕ_B=0.5-0.7$. We explore possible connections of these variabilities with the intrabinary shock and magnetic activity on the low mass secondary.

description: This article studies the evolution of opinions and interpersonal influence structures in a group of agents as they discuss a sequence of issues, each of which follows an opinion dynamics model. In this work, we propose a general opinion dynamics model and an evolution of interpersonal influence structures based on the model of reflected appraisals proposed by Friedkin. Our contributions can be summarized as follows: (i) we introduce a model of opinion dynamics and evolution of interpersonal influence structures between issues viewed as a best response cost minimization to the neighbor's actions, (ii) we show that DeGroot's and Friedkin-Johnsen's models of opinion dynamics and their evolution of interpersonal influence structures are particular cases of our proposed model, and (iii) we prove the existence of an equilibrium. This work is a step towards providing a solid formulation of the evolution of opinions and interpersonal influence structures over a sequence of issues.

description: The submitted paper regards the example of the Conformal Field Theory on a 2d manifold which metric has a point-like singularity.Since this manifold is not conformally equivalent to that with the flat space-time metric,it's naturally to expect that the theory cannot be trivially reduced to the well-known consideration of the CFT on a plane,and some modifications are needed.Particularly,this paper shows how the vacuum of the theory on a singular surface differs from the vacuum of the BPZ theory.Namely,this vacuum would not be SL(2,C)-invariant and the expressions for the correlation functions should be modified. As a consequence of that,some "effective mass" is brought to the theory.

description: We propose a novel measurement technique that exploits the high coherent controllability of multi-comb systems, which corresponds to a generalization of the frequency control between the comb sources. In this paper, we particularly focus on the arbitrary relative carrier envelope phase (CEP) control through the relative offset frequency of two combs. We successfully demonstrate polarization-modulated comb generation and its coherent detection in the developed system. The proof-of-principle experiment indicates the potential of multi-comb systems, enabling a rapid, precise, and arbitrary coherent modulation method utilized for a wide variety of metrological applications.

description: We present a geomorphological map on a scale of 1:15,000, with detailed sedimentological descriptions, and a general relative spatio-temporal depositional reconstruction of Quaternary sediments in the Planica-Tamar Valley (NW Slovenia). After the Last Glacial Maximum, the retreating Quaternary glacier deposited large amounts of glacial sediments. These were followed by Holocene sediments, which differ in their sedimentological characteristics, transport mechanisms, and morphology. These sediments are deposited as sedimentary bodies with complex depositional geometries. They form areas of active, partly active, and inactive sedimentation in response to local/regional climate and bedrock geology. Previous research of the valley was mainly focused on bedrock mapping, while almost completely neglecting Quaternary deposits. This work is the first broader analysis of Quaternary sedimentary deposits in the research area, which offers an insight into the complex geomorphological and sedimentological processes, which shape the current mountainous landscape.
Bi-metric Gravity and "Dark Matter"

Publisher: name: arXiv
Year: 2000
Subjects: subject: Astrophysics (astro-ph)
subject: FOS: Physical sciences

description: We present a bi-metric theory of gravity containing a length scale of galactic size. For distances less than this scale the theory satisfies the standard tests of General Relativity. For distances greater than this scale the theory yields an effective gravitational constant much larger than the locally observed value of Newton's constant. The transition from one regime to the other through the galactic scale can explain the observed rotation curves of galaxies and hence the effects normally attributed to the presence of dark matter. Phenomena on an extragalactic scale such as galactic clusters and the expansion of the universe are controlled by the enhanced gravitational coupling. This provides an explanation of the missing matter normally invoked to account for the observed value of Hubble's constant in relation to observed matter.

description: The Biot-Savart law is a well-known and powerful theoretical tool used to calculate magnetic fields due to currents in magnetostatics. We extend the range of applicability and the formal structure of the Biot-Savart law to electrostatics by deriving a Biot-Savart-like law suitable for calculating electric fields. We show that, under certain circumstances, the traditional Dirichlet problem can be mapped onto a much simpler Biot-Savart-like problem. We find an integral expression for the electric field due to an arbitrarily shaped, planar region kept at a fixed electric potential, in an otherwise grounded plane. As a by-product we present a very simple formula to compute the field produced in the plane defined by such a region. We illustrate the usefulness of our approach by calculating the electric field produced by planar regions of a few nontrivial shapes.

description: Two intervals of the Travis Peak Formation were cored in the Clayton Williams #1 Sam Hughes well, Panola County, Texas. Core was recovered from 6,834.0 to 6,851.7 ft and from 7,044.0 to 7,110.4 ft. The top of the Travis Peak in this well is at 6,830 ft, so the upper core begins a few feet below the contact with the Sligo Formation.

description: We have observed the intermediate regions of the circumstellar envelope of Mira (o Ceti) in photospheric light scattered by three vibration-rotation transitions of the fundamental band of CO, from low-excited rotational levels of the ground vibrational state, at an angular distance of beta = 2"-7" away from the star. The data were obtained with the Phoenix spectrometer mounted on the 4 m Mayall telescope at Kitt Peak. The spatial resolution is approximately 0.5" and seeing limited. Our observations provide absolute fluxes, leading to an independent new estimate of the mass-loss rate of approximately 3e-7 Msun/yr, as derived from a simple analytic wind model. We find that the scattered intensity from the wind of Mira for 2" < beta < 7" decreases as beta^-3, which suggests a time constant mass-loss rate, when averaged over 100 years, over the past 1200 years.

description: Semiarid ecosystems (including arid, semiarid and dry-subhumid ecosystems) span more than 40% of extant habitats and contain a similar percentage of the human population. Theoretical models and palaeoclimatic data predict a grim future, with rapid shifts towards a desert state, with accelerated diversity losses and ecological collapses. These shifts are a consequence of the special nonlinearities resulting from ecological facilitation. Here, we investigate a simple model of semiarid ecosystems identifying the so-called ghost, which appears after a catastrophic transition from a vegetated to a desert state once a critical rate of soil degradation is overcome. The ghost which involves a slowdown of transients towards the desert state, making the ecosystem to seem stable even though vegetation extinction is inevitable. We use this model to show how to exploit the ecological ghosts to avoid collapse. Doing so involves the restoration of small fractions of desert areas with vegetation capable of maintaining a stable community once the catastrophic shift condition has been achieved. This intervention method is successfully tested under the presence of demographic stochastic fluctuations.

description: The motion of fluid particles as they are pushed along erratic trajectories by fluctuating pressure gradients is fundamental to transport and mixing in turbulence. It is essential in cloud formation and atmospheric transport, processes in stirred chemical reactors and combustion systems, and in the industrial production of nanoparticles. The perspective of particle trajectories has been used successfully to describe mixing and transport in turbulence, but issues of fundamental importance remain unresolved. One such issue is the Heisenberg-Yaglom prediction of fluid particle accelerations, based on the 1941 scaling theory of Kolmogorov (K41). Here we report acceleration measurements using a detector adapted from high-energy physics to track particles in a laboratory water flow at Reynolds numbers up to 63,000. We find that universal K41 scaling of the acceleration variance is attained at high Reynolds numbers. Our data show strong intermittency---particles are observed with accelerations of up to 1,500 times the acceleration of gravity (40 times the root mean square value). Finally, we find that accelerations manifest the anisotropy of the large scale flow at all Reynolds numbers studied.

description: Average porosity distributions in the Wolfcamp deep-basin aquifer are studied to discern the geographic trends in effective porosity throughout the Palo Duro Basin. Highly resolved, log-derived porosity data are used to improve porosity resolution in computer-simulated areal groundwater modeling. Assessing vertical distributions of lithology and porosity in each of the wells studied involves cross-plotted neutron and density porosity log responses, which more accurately identify lithology and porosity than cross-plotted neutron porosity and acoustic (interval travel time) responses. Subsequent analyses of log-derived porosity distributions yield information about the total effective pore volume (movable water) in the Wolfcamp aquifer, in addition to enhancing the accuracy of estimating deep-brine velocities and travel times in its basin-wide traverse. Northeastward, basin-wide travel times range between 2.5 x 10^5 and 2.0 x 10^6 years, indicating the potential frequency of basin flushing across the basin.

description: We report the first measurement of the fusion excitation functions for $^{39,47}$K + $^{28}$Si at near-barrier energies. Evaporation residues resulting from the fusion process were identified by direct measurement of their energy and time-of-flight with high geometric efficiency. At the lowest incident energy, the cross-section measured for the neutron-rich $^{47}$K induced reaction is ~6 times larger than that of the $β$-stable system. The experimental data are compared with both a dynamical deformation model and coupled channels calculations (CCFULL).

description: Joints are fractures or partings in a rock that exhibit no displacement (Bates and Jackson, 1980, p. 334). Two styles of joints are systematic joints and nonsystematic joints (Hodgson, 1961). Systematic joints occur in sets. Joints composing each set are subparallel and are commonly orthogonal to the upper and lower surfaces of the rock units in which they are present. Nonsystematic joints display no preferred orientation and truncate against systematic joints.
Spacetime Diffeomorphisms and Topological W-Infinity Symmetry in Two Dimensional Topological String Theory

description: This paper analyzes spacetime symmetries of topological string theory on a two dimensional torus, and points out that the spacetime geometry of the model is that of the Batalin-Vilkovisky formalism. Previously I found an infinite symmetry algebra in the absolute BRST cohomology of the model. Here I find an analog of the BV $Δ$ operator, and show that it defines a natural semirelative BRST cohomology. In the absolute cohomology, the ghost-number-zero symmetries form the algebra of all infinitesimal spacetime diffeomorphisms, extended at non-zero ghost numbers to the algebra of all odd-symplectic diffeomorphisms on a spacetime supermanifold. In the semirelative cohomology, the symmetries are reduced to $w_\infty$ at ghost number zero, and to a topologically twisted N=2 $w_\infty$ superalgebra when all ghost numbers are included. I discuss deformations of the model that break parts of the spacetime symmetries while preserving the topological BRST symmetry on the worldsheet. In the absolute cohomology of the deformed model, another topological $w_\infty$ superalgebra may emerge, while the semirelative cohomology leads to a bosonic $w_\infty$ symmetry.

description: We summarise the main results on the faint submillimeter (submm) galaxy population which have come from the SCUBA Cluster Lens Survey. We detail our current understanding of the characteristics of these submm-selected galaxies across wavebands from X-rays to radio. After presenting the main observational properties of this population we conclude by discussing the nature of these distant, ultraluminous infrared galaxies and their relationship to other high-redshift populations.

Pressure determinations for incompressible fluids and magnetofluids

description: Certain unresolved ambiguities surround pressure determinations for incompressible flows, both Navier-Stokes and magnetohydrodynamic. For uniform-density fluids with standard Newtonian viscous terms, taking the divergence of the equation of motion leaves a Poisson equation for the pressure to be solved. But Poisson equations require boundary conditions. For the case of rectangular periodic boundary conditions, pressures determined in this way are unambiguous. But in the presence of "no-slip" rigid walls, the equation of motion can be used to infer both Dirichlet and Neumann boundary conditions on the pressure P, and thus amounts to an over-determination. This has occasionally been recognized as a problem, and numerical treatments of wall-bounded shear flows usually have built in some relatively ad hoc dynamical recipe for dealing with it, often one which appears to "work" satisfactorily. Here we consider a class of solenoidal velocity fields which vanish at no-slip walls, have all spatial derivatives, but are simple enough that explicit analytical solutions for P can be given. Satisfying the two boundary conditions separately gives two pressures, a "Neumann pressure" and a "Dirichlet pressure" which differ non-trivially at the initial instant, even before any dynamics are implemented. We compare the two pressures, and find that in particular, they lead to different volume forces near the walls. This suggests a reconsideration of no-slip boundary conditions, in which the vanishing of the tangential velocity at a no-slip wall is replaced by a local wall-friction term in the equation of motion.
