description: We consider the quantum evolution of a pair of interacting atoms in a three dimensional isotropic trap where the interaction strength is quenched from one value to another. Using exact solutions of the static problem we are able to evaluate time-dependent observables such as the overlap between initial and final states and the expectation value of the separation between the two atoms. In the case where the interaction is quenched from the non-interacting regime to the strongly interacting regime, or vice versa, we are able to obtain analytic results. Examining the overlap between the initial and final states we show that when the interaction is quenched from the non-interacting to strongly interacting regimes the early time dependence dynamics are consistent with theoretical work in the single impurity many-body limit. When the system is quenched from the strongly to non-interacting regime we predict large oscillations in the separation between the two atoms, which arises from a logarithmic divergence due to the zero-range nature of the interaction potential.

Modifying method of constructing quantum codes from highly entangled states

Subjects: subject: Quantum Physics (quant-ph)
subject: FOS: Physical sciences

description: There is a connection between classical codes, highly entangled pure states (called k-uniform or absolutely maximally entangled (AME) states), and quantum error correcting codes (QECCs). This leads to a systematic method to construct stabilizer QECCs by starting from a k-uniform state or the corresponding classical code and tracing out one party at each step. We provide explicit constructions for codewords, encoding procedure and stabilizer formalism of the QECCs by describing the changes that partial traces cause on the corresponding generator matrix of the classical codes. We then modify the method to produce another set of stabilizer QECCs that encode a logical qudit into a subspace spanned by AME states. This construction produces quantum codes starting from an AME state without tracing out any party. Therefore, quantum stabilizer codes with larger codespace can be constructed.

description: The purpose of this research was to compare nitrous oxide (N2O) emissions using the IPCC methods − first (Tier 1) and second level (Tier 2). Calculation on the second level was performed using a Global Nitrous Oxide Calculator (GNOC). The calculations showed that based on the Tier 1 methodology average N2O emissions for Poland were 3.51 kg N/ha, whereas for the GNOC calculator − 2.74 kg N/ha. The obtained results indicate that the use of GNOC calculator which takes into account agro-environmental conditions allow for accurate estimations of N2O emissions when drawing up reports in accordance with the commitments on reporting greenhouse gas (GHG) emissions.

description: In this letter we present the first implementation of a quantum coin tossing protocol. This protocol belongs to a class of ``two-party'' cryptographic problems, where the communication partners distrust each other. As with a number of such two-party protocols, the best implementation of the quantum coin tossing requires qutrits. In this way, we have also performed the first complete quantum communication protocol with qutrits. In our experiment the two partners succeeded to remotely toss a row of coins using photons entangled in the orbital angular momentum. We also show the experimental bounds of a possible cheater and the ways of detecting him.

Renormalization-Group Analysis of Layered Sine-Gordon Type Models

description: We analyze the phase structure and the renormalization group (RG) flow of the generalized sine-Gordon models with nonvanishing mass terms, using the Wegner-Houghton RG method in the local potential approximation. Particular emphasis is laid upon the layered sine-Gordon (LSG) model, which is the bosonized version of the multi-flavour Schwinger model and approaches the sum of two ``normal'', massless sine-Gordon (SG) models in the limit of a vanishing interlayer coupling J. Another model of interest is the massive sine-Gordon (MSG) model. The leading-order approximation to the UV (ultra-violet) RG flow predicts two phases for the LSG as well as for the MSG, just as it would be expected for the SG model, where the two phases are known to be separated by the Coleman fixed point. The presence of finite mass terms (for the LSG and the MSG) leads to corrections to the UV RG flow, which are naturally identified as the ``mass corrections''. The leading-order mass corrections are shown to have the following consequences: (i) for the MSG model, only one phase persists, and (ii) for the LSG model, the transition temperature is modified. Within the mass-corrected UV scaling laws, the limit of J -> 0 is thus nonuniform with respect to the phase structure of the model. The modified phase structure of general massive sine-Gordon models is connected with the breaking of symmetries in the internal space spanned by the field variables. For the LSG, the second-order subleading mass corrections suggest that there exists a cross-over regime before the IR scaling sets in, and the nonlinear terms show explicitly that higher-order Fourier modes appear in the periodic blocked potential.

The neurocognitive correlates of formal thought disorder in schizophrenia
Creators: name: Weinstein, Sara
Publisher: name: University of British Columbia
Year: 2011

description: Formal thought disorder is among the pathognomonic symptoms of schizophrenia, presenting as irregularities in the structure of speech that result in disorganized or incoherent discourse. Evidence from neuroimaging and behavioural research indicates abnormalities in semantic, linguistic and executive processing all contribute to the expression of this symptom. Additionally, changes in grey matter volume in regions of cortex supporting these functions, particularly the left posterior superior temporal lobe, correlate with the severity of thought disorder. The program of study this thesis represents was broadly focused, with the goal of increasing our understanding of the neurocognitive basis of this symptom. Thought disorder has the curious quality of displaying severe dysfunction in one language modality, expression, while function in another, reception, is intact. The first study used functional magnetic resonance imaging to investigate the source of this disparity, by assessing brain activation during listening to speech. The second study expanded on the first, incorporating structural magnetic resonance imaging data into a mediation analysis with the functional and symptom data, to test whether increased activation mediates the association between reduced cortical grey matter volume and severity of thought disorder. As evidence increasingly indicates impaired context processing in thought disorder, the third study investigated the impact of symptom severity on the context-dependant automatic and controlled processes contributing to word recognition. Finally, the fourth study assessed sub clinical thought disorder in a high schizotypy sample, to determine if speech disorder is among the cognitive variables in this population that exhibit continuity with schizophrenia. The results indicate that increased cortical activation in the left posterior temporal lobe may underlie preserved receptive language function in thought disorder. A proof-of-principle mediation analysis demonstrated that functional and structural brain abnormalities are interdependent and should be considered as such when investigating the neurophysiology of symptom expression. Deficient processing of linguistic context results in failures in both controlled and automatic processes contributing to word recognition. Finally, the speech abnormalities characterizing thought disorder are not associated with normal variation in schizotypy, indicating they may be predictive of transition to psychotic illness in high risk individuals.
Geochemistry of natural wetlands in former uranium milling sites (eastern Germany) and implications for uranium retention

description: Discharge from former uranium mining and milling areas is world wide a source of elevated uranium contents in wetlands. The efficiency of organic rich wetland environments for entrapment and accumulation of uranium was assessed in this work using hydrogeochemical field studies of natural small-sized wetlands in Thuringia and Saxony, Eastern Germany. The objective was to estimate, if artificial wetlands can be used in a similar way: as a sustainable 'passive' treatment methodology. World wide, as an experiment a first dozen of such systems is implemented for uranium bearing mine waters, primarily aiming at uranium reduction and precipitation. Pore water and solid phase samples were collected from the upper decimetres of substrate profiles in minerotrophic volunteer wetlands and natural fen-type wetlands which facilitate uranium accumulation. Elemental analyses, correlation techniques and sequential chemical extraction were applied to evaluate retention mechanisms (e.g., reduction, mineral sorption). No dominant process was pronounced, but the bulk of uranium is retained in moderately labile forms, predominantly as operationally defined organically bound or acid soluble (‘specifically adsorbed’) phases. Macrophyte intracellular uranium accumulation (‘phytoaccumulation’) is not responsible for the high uranium concentrations in the wetland substrates. Although there is no evidence for stable U(IV) mineralisation via ‘reductive precipitation’, high accumulation efficiency of the wetlands is obvious, resulting from processes regarded as more labile. According to the findings, the construction target of wetlands has to be reconsidered, not primarily aiming at uranium reduction.

description: The aim of the study was to determine the level of self-sufficiency in the production of basic types of fruit and to measure its changes in the period 2008-2013. The study analyzed the following groups and species: fruit total (excluding citrus fruits), apples, pears, berries. For analyzing the level of consumption self-sufficiency a modified self-sufficiency rate was used, which expresses the degree of satisfying the internal needs in a given area on the main groups of agricultural food products from domestic production. In the period 2008-2013 total self-sufficiency in fruit production in the country remained at a satisfactory level. Among the provinces there were clear centers of high production manifold exceeding their internal needs, such as the provinces of Lubelskie, Świętokrzyskie, Masovia and Łódzkie.

description: The study estimates the impact of change in urea price on the economic optimum level of N fertilizer use in HYV rice and its yield in Bangladesh using a large set of experimental data of BRRIfrom 15 regions covering an 11 year period (2001–2011). Results revealed that the level of N fertilizer usedin experiments to increase HYV rice yield was far lower than the economic optimum level in Aman and Boro seasonsbut higher in Aus season. The discrepancy was highest for HYV Boro rice closely followed by HYV Aman rice. Simulation exercise revealed that an increase in real price of urea by 50% will exert a 4% reduction in optimum dose of N fertilizer in HYV Amanrice and reduce yield by 101.2 kg/ha which issubstantial. The corresponding effect on HYV Bororice is relatively lowerand negligible for HYV Aus rice. The result highlights the dilemma and the detrimental effect of urea price increase on the yield ofHYV Aman rice which is the main source of foodgrain supply for the nation. Therefore, price policy should be geared towards controlling relative price of urea which can be met by a combination of subsidizing urea price and/or improving rice price.

Höhenverluste von Moorböden – eine Herausforderung für Wasserwirtschaft und Landnutzung
Subsidence of peat soils – a challenge for water management and land use
Creators: name: Trepel, Michael
Publisher: name: FID GEO
Year: 2015

description: Abstract: Drained peat soils subside and lose height. This vicious circle of peat use was managed in the past with regularly draining activities for sustaining intensive land use. This approach will not work so easily in the future, because the hydrological and physical limits of drainage are often reached. This contribution presents in the first part more accurate approaches for predicting subsidence rates of peat soils than the widely used rule of thumb values. Recent concepts for peat conserving land use, which minimize subsidence, are discussed. Implementing these concepts requires in large peatland areas a moderated process supported by politics and environmental administration.
description: Zusammenfassung: Entwässerte Moorböden sacken und verlieren dabei an Höhe. Diesem „Teufelskreis“ der Moornutzung wurde bisher bei intensiver Landnutzung durch regelmäßige – das heißt wiederholte – Entwässerung begegnet. Zukünftig wird dies nicht mehr so einfach möglich sein, da der erneuten Entwässerung hydrologisch bedingte, physikalische Grenzen gesetzt sind. Daher werden in diesem Beitrag Verfahren zur genaueren Abschätzung der Höhenverluste als die bisher meist verwendeten Faustzahlen vorgestellt und anschließend Vorschläge für torfschonende Bewirtschaftungsformen diskutiert, mit denen Höhenverluste vermindert werden können. Um diese Konzepte in großen Niederungen umzusetzen, muss dieser Entscheidungsprozess von Politik und Verwaltung begleitet werden.

description: Turbulence has a profound impact on the evolution of gas and dust in protoplanetary disks (PPDs), from driving the collisions and the diffusion of dust grains, to the concentration of pebbles in giant vortices, thus, facilitating planetesimal formation. The Vertical Shear Instability (VSI) is a hydrodynamic mechanism, operating in PPDs if the local rate of thermal relaxation is high enough. Previous studies of the VSI have, however, relied on the assumption of constant cooling rates, or neglected the finite coupling time between the gas particles and the dust grains. Here, we present the results of hydrodynamic simulations of PPDs with the PLUTO code that include a more realistic thermal relaxation prescription, which enables us to study the VSI in the optically thick and optically thin parts of the disk under consideration of the thermal dust-gas coupling. We show the VSI to cause turbulence even in the optically thick inner regions of PPDs in our two- and three-dimensional simulations. The collisional decoupling of dust and gas particles in the upper atmosphere and the correspondingly inefficient thermal relaxation rates lead to the damping of the VSI turbulence. Long-lived anticyclonic vortices form in our three-dimensional simulation. These structures emerge from the turbulence in the VSI-active layer, persist over hundreds of orbits and extend vertically over the whole extent of the turbulent region. We conclude that the VSI leads to turbulence and the formation of long-lived dust traps within $\pm$3 pressure scale heights distance from the disk midplane

description: The study analyzes the change of cropping patterns and its impacts on farmer’s livelihood using farm level survey data. The study reveals that four cropping patterns such as P1 (Boro rice – Fallow - T. Aman rice); P2 (Brinjal -T. Aman rice – Fallow); P3 (Boro rice - T. Aman – Fallow) and P4 (Bean – Fallow - T. Aman rice). It was evident from the study that the cropping pattern P2 (Brinjal - T. Aman rice – Fallow) earned the highest profit among the selected cropping patterns. The results also indicate that the human capital increased 59.33, 68.00 and 65.33 percent; social capital increased 48.88, 52.22 and 57.77 percent as well as physical capital increased 48.00, 67.78 and 86.11 percent of the marginal, small and medium farmers respectively due to change in cropping patterns and their productivity. This study also reports that natural capital and financial capital also increased for marginal, small and medium farmers.

description: Recent Chandra and XMM X-ray observations of rich clusters of galaxies have shown that the amount of hot gas which is cooling below ~1 keV is generally more modest than previous estimates. Yet, the real level of the cooling flows, if any, remains to be clarified by making observations sensitive to different temperature ranges. As a follow-up of the FUSE observations reporting a positive detection of the OVI doublet at 1032, 1038 Angstrom in the cluster of galaxies Abell 2597, which provided the first direct evidence for ~3x10^5 K gas in a cluster of galaxies, we have carried out sensitive spectroscopy of two rich clusters, Abell 2029 and Abell 3112 (z~0.07) located behind low HI columns. In neither of these clusters could we detect the OVI doublet, yielding fairly stringent limits of ~27 Msun yr-1 (Abell 2029) and ~25 Msun yr-1 (Abell 3112) to the cooling flow rates using the 10^5-10^6 K gas as a tracer. The non-detections support the emerging picture that the cooling-flow rates are much more modest than deduced from earlier X-ray observations.

description: The satellite populations of the Milky Way, and Milky-Way-mass galaxies in the local universe, have been extensively studied to constrain dark-matter and galaxy-evolution physics. Recently, there has been a shift to studying satellites of hosts with stellar masses between that of the Large Magellanic Cloud and the Milky Way, since they can provide further insight on hierarchical structure formation, environmental effects on satellites, and the nature of dark-matter. Most work is focused on the Local Volume, and little is still known about low-mass host galaxies at higher red-shift. To improve our understanding of the evolution of satellite populations of low-mass hosts, we study satellite galaxy populations as a function of host stellar mass $9.5 < \log(M_*/M_\odot) < 10.5$ and redshifts $0.1 < z < 0.8$ in the COSMOS survey, making this the first study of satellite systems of low-mass hosts across half the age of the universe. We find that the satellite populations of low-mass host galaxies, which we measure down to satellite masses equivalent to the Fornax dwarf spheroidal satellite of the Milky Way, remain mostly unchanged through time. We observe a weak dependence between host stellar mass and number of satellites per host, which suggests that the stellar masses of the hosts are in the power-law regime of the stellar mass to halo mass relation $(M_*-M_{\text{halo}})$ for low-mass galaxies. Finally, we test the constraining power of our measured cumulative luminosity function to calculate the low-mass end slope of the $M_*-M_\text{halo}$ relation. These new satellite luminosity function measurements are consistent with $Λ$CDM predictions.

description: It was shown by Ford and Roman in 1996 that quantum field theory severely constrains wormhole geometries on a macroscopic scale. The first part of this paper discusses a wide class of wormhole solutions that meet these constraints. The type of shape function used is essentially generic. The constraints are then discussed in conjunction with various redshift functions. Violations of the weak energy condition and traversability criteria are also considered. The second part of the paper analyzes analogous time-dependent (dynamic) wormholes with the aid of differential forms. It is shown that a violation of the weak energy condition is not likely to be avoidable even temporarily.

Publisher: name: Geozon Science Media
Year: 1973

description: Zwischen Melvich und Cape Wrath an der Nordküste Sutherlands wurden solche morphologischen Phänomene erfaßt und ausgewertet, die auf postglaziale Meeresstände zurückzuführen sind. Die vertikale Verteilung dieser Formen konzentriert sich auf vier Höhenzonen. Je älter diese Zonen sind, desto höher liegen sie heute über NN und desto größer ist sowohl ihre vertikale Ausdehnung als auch ihre Neigung nach Westen. Die oberste Zone (im Osten zwischen 21 m und 25,5 m ü. NN und im Westen zwischen 12 m und 16,5 m ü. NN) steht in Beziehung zu Fluvioglazialablagerungen des Highland Readvance; sie entstand also in der jüngeren Dryaszeit. Die Zweitälteste Zone (im Osten zwischen 12 m und 15 m ü. NN und im Westen zwischen 10 m und 13 m ü. NN) geht auf das Präboreal zurück. Eine boreale Torfschicht unter der zweitjüngsten Zone (im Osten zwischen 7 m und 9,5 m ü. NN und im Westen zwischen 6 m und 8,5 m ü. NN) aus dem Atlantikum stützt diese Chronologie. Im Subboreal entstand die jüngste, gegenwärtig noch horizontal angeordnete Strandzone zwischen 3 m und 5,5 m ü. NN. Auf Grund der Isobasenanordnung an der Nordküste kann auf ein Unterzentrum der Vereisung hinter der Küstenlinie im Osten des Untersuchungsgebietes geschlossen werden.

description: A Higgs particle produced in association with a Z boson and decaying into weak boson pairs is searched for in 336.4 1/pb of data collected by the L3 experiment at LEP at centre-of-mass energies from 200 to 209 GeV. Limits on the branching fraction of the Higgs boson decay into two weak bosons as a function of the Higgs mass are derived. These results are combined with the L3 search for a Higgs boson decaying to photon pairs. A Higgs produced with a Standard Model e+e- --> Zh cross section and decaying only into electroweak boson pairs is excluded at 95% CL for a mass below 107 GeV.

description: We consider one-dimensional quantum spin chain, which is called XX model, XX0 model or isotropic XY model in a transverse magnetic field. We study the model on the infinite lattice at zero temperature. We are interested in the entropy of a subsystem [a block of L neighboring spins]. It describes entanglement of the block with the rest of the ground state. G. Vidal, J.I. Latorre, E. Rico, and A. Kitaev showed that for large blocks the entropy scales logarithmically. We prove the logarithmic formula for the leading term and calculate the next term. We discovered that the dependence on the magnetic field interacting with spins is very simple: the magnetic field effectively reduce the size of the subsystem. We also calculate entropy of a subsystem of a small size. We also evaluated Renyi and Tsallis entropies of the subsystem. We represented the entropy in terms of a Toeplitz determinant and calculated the asymptotic analytically.

description: We propose a new two-stage model for acceleration of electrons in solar flares. In the first stage, electrons are accelerated stochastically in a post-reconnection turbulent downflow. The second stage is the reprocessing of a subset of these electrons as they pass through a weakly compressive fast shock above the apex of the closed flare loop on their way to the chromosphere. We call this the "shock reprocessing" model. The model reproduces the energy dependent arrival time delays observed for both the pulsed and smooth components of impulsive solar flare x-rays with physically reasonable parameters for the downflow region. The model also predicts an emission site above the loop-top, as seen in the Masuda flare. The loop-top source distinguishes the shock reprocessing model from previous models. The model makes testable predictions for the energy dependence of footpoint pulse strengths and the location and spectrum of the loop-top emission, and can account for the observed soft-hard-soft trend in the spectral evolution of footpoint emission. Our model highlights the concept that reconnection is an acceleration environment rather than a single process. Which combination of processes operate may depend on the initial conditions that determine, for example, whether the reconnection downflow is turbulent. The shock reprocessing model comprises one such combination.

description: We discuss constraints on SUSY models with non-unified gaugino masses and R_P conservation. We derive a lower bound on the neutralino mass combining the direct limits from LEP, the indirect limits from gmuon, bsgamma, Bsmumu and the relic density constraint from WMAP. The lightest neutralino (mneutralino=6GeV) is found in models with a light pseudoscalar with MA<200GeV and a large value for $tanβ$. Models with heavy pseudoscalars lead to mneutralino>18(29)GeV for $\tanβ=50(10)$. We show that even a very conservative bound from the muon anomalous magnetic moment can increase the lower bound on the neutralino mass in models with mu<0 and/or large values of $\tanβ$. We then examine the potential of the Tevatron and the direct detection experiments to probe the SUSY models with the lightest neutralinos allowed in the context of light pseudoscalars with high $\tanβ$. We also examine the potential of an e+e- collider of 500GeV to produce SUSY particles in all models with neutralinos lighter than the W. In contrast to the mSUGRA models, observation of at least one sparticle is not always guaranteed.

description: Conversational systems are of primary interest in the AI community. Chatbots are increasingly being deployed to provide round-the-clock support and to increase customer engagement. Many of the commercial bot building frameworks follow a standard approach that requires one to build and train an intent model to recognize a user input. Intent models are trained in a supervised setting with a collection of textual utterance and intent label pairs. Gathering a substantial and wide coverage of training data for different intent is a bottleneck in the bot building process. Moreover, the cost of labeling a hundred to thousands of conversations with intent is a time consuming and laborious job. In this paper, we present an intent discovery framework that involves 4 primary steps: Extraction of textual utterances from a conversation using a pre-trained domain agnostic Dialog Act Classifier (Data Extraction), automatic clustering of similar user utterances (Clustering), manual annotation of clusters with an intent label (Labeling) and propagation of intent labels to the utterances from the previous step, which are not mapped to any cluster (Label Propagation); to generate intent training data from raw conversations. We have introduced a novel density-based clustering algorithm ITER-DBSCAN for unbalanced data clustering. Subject Matter Expert (Annotators with domain expertise) manually looks into the clustered user utterances and provides an intent label for discovery. We conducted user studies to validate the effectiveness of the trained intent model generated in terms of coverage of intents, accuracy and time saving concerning manual annotation. Although the system is developed for building an intent model for the conversational system, this framework can also be used for a short text clustering or as a labeling framework.

Estimation of the brain's hemodynamic response from fMRI images using the Eigenvector Based Algorithm for Multichannel Deconvolution
Creators: name: Gadala, Marwa
Publisher: name: University of British Columbia
Year: 2011

description: The ability to determine the brain's hemodynamic response without relying on an input function would be an extremely valuable asset in a large number of medical applications, and today, functional Magnetic Resonance Imaging (fMRI) is one of the leading methods in developing a better understanding of the human brain. Assuming the linear timeinvariant model for the observed fMRI response ([1], [2], [4]), this work provides an estimate of the hemodynamic brain response both on a regional and on an individual voxel level, as well as provides an estimate of the input signal that excited the brain's response. The solution to this problem is achieved using the Eigenvector-Based Algorithm for Multichannel Blind Deconvolution (EVAM) ([5], [6]) combined with Independent Component Analysis (ICA) [23]. The resulting estimate of the input signal produced by the proposed method could prove to be a valuable insight into the actual signal that triggered the brain during the experiment, and not the ideal signal that should have triggered it based on experimental observations. Also, contrary to previous works, no prior assumptions regarding the shape or order of the brain's response are made. When compared to non-blind identification algorithms traditionally used in the literature, the results show a significant improvement as the shape of the hemodynamic brain response conforms with current medical understandings. Furthermore, the estimated hemodynamic brain response is then used as a basis to determine active and inactive voxels. Two clustering methods, K-Means Clustering and Correlation-Based Clustering, are compared. Correlation-Based Clustering is found to be superior and is thus used to spatially map the active and inactive voxels. Spatial maps of important brain regions yield promising results where spatial sparseness is not characteristic of the images. Finally, a preliminary comparison between a healthy subject and a subject inflicted with Parkinson's disease yields promising differences, especially in the left primary cortex where very little activation was observed. Interestingly, symptoms of Parkinson's disease are thought to be a result of decreased stimulation of the motor cortex. Although no major medical conclusions can be made due to the risk of incorrectly attributing intersubject variability to differences due to Parkinson's disease, this preliminary comparison shows promising results that encourage future research in this area

description: The generation of finite energy packets of X-waves is analysed in normally dispersive cubic media by using an X-wave expansion. The 3D nonlinear Schroedinger model is reduced to a 1D equation with anomalous dispersion. Pulse splitting and beam replenishment as observed in experiments with water and Kerr media are explained in terms of a higher order breathing soliton. The results presented also hold in periodic media and Bose-condensed gases.
