ancient Greek vase painting
Dareios Krater

description: The article broadens the perspectives already developed in previous works dedicated to the relationship between ancient tragic theater and vase painting, starting from precise iconographic indicators recognizable in Greek vases. In particular, it demonstrates how many references to the theatrical plays might be perceived by the owners of the vases, through an accurate selection of elements described in the tragedies as signals of the mythical stories portrayed on them. The case study of the famous ‘Cratere di Dario’ from the Apulian area at Canosa offers a clear demonstration of this method.
Bright Solitary-Matter-Wave Collisions in a Harmonic Trap: Regimes of Soliton-like Behaviour

description: Systems of solitary-waves in the 1D Gross-Pitaevskii equation, which models a trapped atomic Bose-Einstein condensate, are investigated theoretically. To analyse the soliton-like nature of these solitary-waves, a particle analogy for the solitary-waves is formulated. Exact soliton solutions exist in the absence of an external trapping potential, which behave in a particle-like manner, and we find the particle analogy we employ to be a good model also when a harmonic trapping potential is present. In the case of two solitons, the particle model is integrable, and the dynamics are completely regular. The extension to three particles supports chaotic regimes. The agreement between the particle model and the wave dynamics remains good even in chaotic regimes. In the case of a system of two solitary waves of equal norm, the solitons are shown to retain their phase difference for repeated collisions. This implies that soliton-like regimes may be found in 3D geometries where solitary waves can be made to repeatedly collide out of phase, stabilising the condensate against collapse.

description: In order to clarify the impact of urbanization development on food production, based on panel data from 31 provinces (municipalities, autonomous regions) in China from 2005 to 2015, using a fixed effect model, the paper found that the urbanization rate has a negative impact on per capita food production, and finally made the related policy recommendations. The above research is of significance for promoting the development of urbanization and ensuring food security.
Sexual and marital communication : and perceived marital adjustment
Creators: name: Vogel, Noelle Anne
Publisher: name: University of British Columbia
Year: 2010

description: This study sought to examine the relationship between marital quality and interspousal sexual communication. The study also sought to examine the relationships between sexual communication and marital communication and perceived quality of relationships. A purposive sample of forty four couples was drawn from throughout the lower mainland of British Columbia, Canada. Twenty two couples who were receiving marital counselling for distressed relationships were drawn and constituted Group One. Twenty two couples who were not seeking therapy and who judged their marriages to be satisfactory were drawn and constituted Group Two. Both husbands and wives within each sample were mailed the following questionnaires: The Dyadic Adjustment Scale, The Marital Communication Inventory and The Sexual Communication Inventory. Four hypotheses were tested. Hypotheses One, Two and Three were tested using independent groups t-test for the difference between means to determine if there was a statistically significant difference between the means of the two groups on different variables of marital adjustment. Hypothesis Four was tested using the Pearson Product Moment correlation coefficient to establish the relationships between variables. The null hypothesis was rejected in each case. The results of the study reconfirm that there is a strong positive correlation between marital adjustment and interspousal communication. The study further demonstrates a strong correlation between open sexual communication and marital adjustment and between inhibited sexual communication and marital distress. The results of Hypothesis Four demonstrate that the correlations between sexual communication and marital adjustment and between sexual communication and marital communication are group specific and statistically significant between groups.

description: Leading order higher-spin corrections to the linearized higher-spin black brane are analyzed in four dimensions. It is shown that the static solution that respects planar symmetry exists in the bosonic case at given order. Its higher-spin Weyl tensors are found in a closed form and are shown to have the double copy origin. The effect of higher-spin fields to form a strictly positive scalar condensate for any values of higher-spin charges is observed.

Topological censorship for Kaluza-Klein space-times

Subjects: subject: General Relativity and Quantum Cosmology (gr-qc)

description: The standard topological censorship theorems require asymptotic hypotheses which are too restrictive for several situations of interest. In this paper we prove a version of topological censorship under significantly weaker conditions, compatible e.g. with solutions with Kaluza-Klein asymptotic behavior. In particular we prove simple connectedness of the quotient of the domain of outer communications by the group of symmetries for models which are asymptotically flat, or asymptotically anti-de Sitter, in a Kaluza-Klein sense. This allows one, e.g., to define the twist potentials needed for the reduction of the field equations in uniqueness theorems. Finally, the methods used to prove the above are used to show that weakly trapped compact surfaces cannot be seen from Scri.

power grid

description: This is the User's Manual for the MATPOWER Optimal Scheduling Tool (MOST), a framework for solving generalized steady-state electric power scheduling problems.

MOST can be used to solve problems as simple as a deterministic, single period economic dispatch problem with no transmission constraints or as complex as a stochastic, security-constrained, combined unit-commitment and multiperiod optimal power flow problem with locational contingency and load-following reserves, ramping costs and constraints, deferrable demands, lossy storage resources and uncertain renewable generation.

While the problem formulation is general and incorporates a full nonlinear AC network model, the current implementation is limited to DC power flow modeling of the network. Some work has been done on an AC implementation, but it is not yet ready for release.

The primary developers of MOST are Carlos E. Murillo-Sanchez and Ray D. Zimmerman, with significant contributions from Daniel Munoz-Alvarez and Alberto J. Lamadrid. It is built on top of MATPOWER, a package of MATLAB/Octave M-files for solving power flow and optimal power flow problems.

description: The lateral Casimir-Polder force between an atom and a corrugated surface should allow one to study experimentally non trivial geometrical effects in quantum vacuum. Here, we derive the theoretical expression of this force in a scattering approach that accounts for the optical properties of the corrugated surface. We show that large corrections to the ``proximity force approximation'' could be measured using present-day technology with a Bose-Einstein condensate used as a vacuum field sensor.

Structural Learning of Probabilistic Sentential Decision Diagrams under Partial Closed-World Assumption

description: Probabilistic sentential decision diagrams are a class of structured-decomposable probabilistic circuits especially designed to embed logical constraints. To adapt the classical LearnSPN scheme to learn the structure of these models, we propose a new scheme based on a partial closed-world assumption: data implicitly provide the logical base of the circuit. Sum nodes are thus learned by recursively clustering batches in the initial data base, while the partitioning of the variables obeys a given input vtree. Preliminary experiments show that the proposed approach might properly fit training data, and generalize well to test data, provided that these remain consistent with the underlying logical base, that is a relaxation of the training data base.

description: The Berry phases for coherent states and squeezed coherent states of Landau levels are calculated. Coherent states of Landau levels are interpreted as a result of a magnetic flux moved adiabatically from infinity to a finite place on the plane. The Abelian Berry phase for coherent states of Landau levels is an analog of the Aharonov- Bohm effect. Moreover, the non-Abelian Berry phase is calculated for the adiabatic evolution of the magnetic field B.

description: By combining expert consultation and field investigation, an evaluation system, consisting of 29 indices in 5 aspects of water safety, water ecology, water management, water landscape and water culture, was established for water ecological civilization construction in coal mining subsidence areas. The weight of the indices was determined using improved group-decision fuzzy analytic hierarchy process and fuzzy mathematical method, and their score was determined according to their value before the pilot and the value at the end of the pilot. Combined with the weight, the actual score of the indices was obtained. Finally, a comprehensive index of water ecological civilization in coal mining subsidence areas was obtained. Through the weight and score of the indices, the construction status, existing problems and future tasks of coal mining subsidence areas were analyzed, in order to provide a reference for the region to further clarify the direction and key tasks of water ecological civilization construction.

description: Superconductivity in iron pnictides is studied by using a two-orbital Hubbard model in the large U limit. The Coulomb repulsion induces an orbital-dependent pairing between charge carriers. The pairing is found mainly from the scattering within the same Fermi pocket. The inter-pocket pair scatterings determine the symmetry of the superconductivity, which is extended s-wave at small Hund's coupling, and d-wave at large Hund's coupling and large U. The former is consistent with recent experiments of ARPES and Andreev reflection spectroscope.

Hypnotherapy and client suitability for the treatment of obesity
Creators: name: Cochrane, Gordon John
Publisher: name: University of British Columbia
Year: 2010

description: This study investigated the suitability of hypnosis for the treatment of obesity. Client suitability was assessed by six concomitant variables and one additional variable that assessed imagery activity which occurred during hypnosis treatment. The imagery assessment was done immediately following treatment. The literature review indicated that to date only preliminary research exists on hypnosis as a treatment for obesity and that most studies have been anecdotal with little or no follow-up. The literature also revealed the need for controlled research to identify the characteristics of clients who can benefit from hypnosis treatment for obesity. The sample consisted of 60 women between the ages of 20 and 65 who were at least 20 percent overweight and were not in another treatment program. The sample was drawn from women in Regina, Saskatchewan and surrounding communities. The experimental groups, hypnosis plus audiotapes (Expau), hypnosis without audio-tapes (Expnau), and the control group (Expcont) were investigated on the basis of weight loss at a six month follow-up. The concomitant variables were suggestibility, as measured by the Barber Suggestibility Scale (BSS); self-concept, as measured by the Tennessee Self Concept Scale (TSCS); quality of the families of origin, as measured by the Family History of Distress Scale (FAM), and age of obesity onset (AGE), education level (EDUC), and economic status (ECSTAT). Multi-modal imagery activity, as measured by the Representational Systems Inventory (RSI), was assessed with the two treatment groups. The dependent measure was weight loss. Analysis of Covariance revealed a significant difference in weight loss between the treatment groups (Expau and Expnau) and the control group (Expcont) but no significant difference between the two treatment groups. It was found that none of the concomitant variables nor imagery activity contributed to the variability in weight loss at the six month follow-up. Selected case studies suggest the importance of resolution of issues stemming from the family of origin, strong personal motivation, minimal ongoing relationship problems and a readiness to work on personal issues that seem related to obesity.

description: Bianchi type $VI_{0}$ massive string cosmological models using the technique given by Letelier (1983) with magnetic field are investigated. To get the deterministic models, we assume that the expansion ($θ$) in the model is proportional to the shear ($σ$) and also the fluid obeys the barotropic equation of state. It was found that vacuum energy density $Λ\propto \frac{1}{t^{2}}$ which matches with natural units. The behaviour of the models from physical and geometrical aspects in presence and absence of magnetic field is also discussed.

description: Aims: We are using the Arecibo Legacy Fast ALFA survey (ALFALFA), which is covering 17% of the sky at 21 cm, to study the HI content of Early-Type galaxies (ETG) in an unbiased way. The aim is to get an overall picture of the hot, warm and cold ISM of ETG, as a function of galaxy mass and environment, to understand its origin and fate, and to relate it to the formation and evolution history of these objects. Methods: This paper deals with the first part of our study, which is devoted to the 8-16 deg. declination strip in the Virgo cluster. In this sky region, using the Virgo Cluster Catalogue (VCC), we have defined an optical sample of 939 ETG, 457 of which are brighter than the VCC completeness limit at B_T=18.0. We have correlated this optical sample with the catalogue of detected HI sources from ALFALFA. Results: Out of the 389 ETG from the VCC with B_T<=18.0, outside the 1 deg. region of poor HI detection around M87, and corrected for background contamination of VCC galaxies without a known radial velocity, only 9 galaxies (2.3%) are detected in HI with a completeness limit of 3.5 and 7.6 x 10^7 Mo of HI for dwarf and giant ETG, respectively. In addition 4 VCC ETG with fainter magnitudes are also detected. Our HI detection rate is lower than previously claimed. The majority of the detected ETG appear to have peculiar morphology and to be located near the edges of the Virgo cluster. Conclusions: Our preliminary conclusion is that cluster ETG contain very little neutral gas, with the exceptions of a few peculiar dwarf galaxies at the edge of the ETG classification and of very few larger ETG, where the cold gas could have a recent external origin.

description: This paper presents a modeling study of the oxidation of cyclohexane from low to intermediate temperature (650-1050 K), including the negative temperature coefficient (NTC) zone. A detailed kinetic mechanism has been developed using computer-aided generation. This comprehensive low-temperature mechanism involves 513 species and 2446 reactions and includes two additions of cyclohexyl radicals to oxygen, as well as subsequent reactions. The rate constants of the reactions involving the formation of bicyclic species (isomerizations, formation of cyclic ethers) have been evaluated from literature data. This mechanism is able to satisfactorily reproduce experimental results obtained in a rapid-compression machine for temperatures ranging from 650 to 900 K and in a jet-stirred reactor from 750 to 1050 K. Flow-rate analyses have been performed at low and intermediate temperatures.

description: A novel approach to learning is presented, combining features of on-line and off-line methods to achieve considerable performance in the task of learning a backgammon value function in a process that exploits the processing power of parallel supercomputers. The off-line methods comprise a set of techniques for parallelizing neural network training and $TD(λ)$ reinforcement learning; here Monte-Carlo ``Rollouts'' are introduced as a massively parallel on-line policy improvement technique which applies resources to the decision points encountered during the search of the game tree to further augment the learned value function estimate. A level of play roughly as good as, or possibly better than, the current champion human and computer backgammon players has been achieved in a short period of learning.

description: We present a new method for articulating scale-dependent topological descriptions of the network structure inherent in many complex systems. The technique is based on "Partition Decoupled Null Models,'' a new class of null models that incorporate the interaction of clustered partitions into a random model and generalize the Gaussian ensemble. As an application we analyze a correlation matrix derived from four years of close prices of equities in the NYSE and NASDAQ. In this example we expose (1) a natural structure composed of two interacting partitions of the market that both agrees with and generalizes standard notions of scale (eg., sector and industry) and (2) structure in the first partition that is a topological manifestation of a well-known pattern of capital flow called "sector rotation.'' Our approach gives rise to a natural form of multiresolution analysis of the underlying time series that naturally decomposes the basic data in terms of the effects of the different scales at which it clusters. The equities market is a prototypical complex system and we expect that our approach will be of use in understanding a broad class of complex systems in which correlation structures are resident.

description: In this work, we present large-scale electron-correlated computations on various conformers of B$_{12}$H$_{12}$ and B$_{12}$H$_{6}$ clusters, to understand the reasons behind the high stability of di-anion icosahedron ($I_{h}$) and cage-like B$_{12}$H$_{6}$ geometries. Although the B$_{12}$-icosahedron is the basic building block in some structures of bulk boron, it is unstable in its free form. Furthermore, its H-passivated entity, i.e., B$_{12}$H$_{12}$ icosahedron is also unstable in free form. However, dianion B$_{12}$H$_{12}$ has been predicted to be stable as a perfect icosahedron in the free-standing form. In order to capture the correct picture for the stability of B$_{12}$H$_{12}^{-2}$ and B$_{12}$H$_{6}$ clusters, we optimized these structures by employing the coupled-cluster singles-doubles (CCSD) approach and cc-pVDZ basis set. We also performed vibrational frequency analysis of the isomers of these clusters, using the same level of theory to ensure the stability of the structures. For all the stable geometries obtained from the vibrational frequency analysis, we additionally computed their optical absorption spectra using the time-dependent density functional theory (TDDFT) approach, at the the B3LYP/6-31G{*} level of theory. Our calculated absorption spectra could be probed in future experiments on these clusters.

Class of quasiprobability distributions of work and initial quantum coherence

Subjects: subject: Quantum Physics (quant-ph)

description: The work is a concept of fundamental importance in thermodynamics. An open question is how to describe the work fluctuation for quantum coherent processes in the presence of initial quantum coherence in the energy basis. With the aim of giving a unified description, here we introduce and study a class of quasiprobability distributions of work, which give an average work equal to the average energy change of the system and reduce to the two-projective measurement scheme for an initial incoherent state. Moreover, we characterize the work with the help of fluctuation relations. In particular, by considering the joint distribution of work and initial quantum coherence, we find a fluctuation theorem involving quantum coherence, from which follows a second law of thermodynamics in the case of initial thermal populations. Furthermore, we propose a way to measure the characteristic function of work and we discuss the negativity of the quasiprobability. The effects of coherence are also investigated for a simple system of a qubit.

Therapeutic relationship and its association with outcome
Creators: name: Moseley, Douglas Charles
Publisher: name: University of British Columbia
Year: 2010

description: This study investigated the association between general relationship factors and outcome in short .term counselling. Twenty five clients who were seeking counselling at various settings in the lower mainland of British Columbia completed instruments that were designed to quantify aspects of their relationship with the therapist. Three models of the therapeutic relationship were examined: Strong's social influence theory; Roger's core conditions; and Bordin's working alliance. It was hypothesized that the three dimensions of Bordin's Working Alliance (bond, task, and goal) would correlate significantly with four outcome measures. Two of the outcome measures utilized did not correlate with any of the relationship variables. Task and Bond correlated significantly (p<.0l and p<.05 respectively) with two indices of outcome and Goal had a significant relationship (p<.05) with one of the outcome measures. Of the other four relationship variables that were included in this study, only the social influence variable of client perceived counsellor attractiveness correlated with outcome measures beyond chance levels.

The above distance moduli are processed for three different compilations of supernovae and a supernovae + GRBs compilation: Union 2.1, JLA, the Pantheon and Union 2.1 + 59 GRBs. For each of the 48 analysed cases we report the relative cosmological parameters, the chi-square, the reduced chi-square, the AIC and the $Q$ parameter. The angular distance as function of the redshift for five cosmologies is reported in the framework of the minimax approximation.

description: We develop a probabilistic machine learning model and use it to screen for new hybrid organic-inorganic perovskites (HOIPs) with targeted electronic band gap. The data set used for this work is highly diverse, containing multiple atomic structures for each of 192 chemically distinct HOIP formulas. Therefore, any property prediction on a given formula must be associated with an irreducible "uncertainty" that comes from its unknown atomic details. As a result, dozens of new HOIP formulas with band gap falling between 1.25 and 1.50 eV were identified and validated against suitable first-principles computations. Through this demonstration we show that the probabilistic deep learning approach is robust, versatile, and can be used to properly quantify this uncertainty. In conclusion, the probabilistic standpoint and approach described herein could be widely useful for the very common and inevitable data uncertainty which is rooted at the incompleteness of information during experiments and/or computations.

description: In the framework of the generalized Rastall theory (GRT), we study the ability of a non-minimal coupling between geometry and matter fields in order to provide a setting which allows for a variable G during the cosmic evolution. In this regard, the compatibility of this theory with Dirac hypothesis on the variations of G is investigated, and additionally, the possibility of obtaining the current accelerated universe is also addressed. In summary, our study indicates that, in GRT, having in hand the G profile, one may find the corresponding non-minimal coupling between the energy source and geometry and vise versa, in a compatible way with the current accelerated universe.

description: In order to better understand the thermal decomposition of polycyclanes, the pyrolysis of tricyclodecane has been studied in a jet-stirred reactor at temperatures from 848 to 933 K, for residence times between 0.5 and 6 s and at atmospheric pressure, in order to obtain a conversion between 0.01 and 25 %. The main products of the reaction are hydrogen, methane, ethylene, ethane, propene, 1,3-cyclopentadiene, cyclopentene, benzene, 1,5-hexadiene, toluene and 3-cyclopentyl-cyclopentene. A primary mechanism containing all the possible initiation steps, including those involving diradicals, as well as propagation reactions has been developed and allows experimental results to be satisfactorily modeled. The main reaction pathways of consumption of tricyclodecane and of formation of the main products have been derived from flow rate and sensitivity analyses.

description: This paper deals with the nonlinear stochastic dynamics of an orchard tower sprayer subjected to random excitations due to soil irregularities. A consistent stochastic model of uncertainties is constructed to describe random loadings and to predict variabilities in mechanical system response. The dynamics is addressed in time and frequency domains. Monte Carlo method is employed to compute the propagation of uncertainties through the stochastic model. Numerical simulations reveals a very rich dynamics, which is able to produce chaos. This numerical study also indicates that lateral vibrations follow a direct energy cascade law. A probabilistic analysis reveals the possibility of large lateral vibrations during the equipment operation.

description: Conformal totally symmetric arbitrary spin currents and shadow fields in flat space-time of dimension greater than or equal to four are studied. Gauge invariant formulation for such currents and shadow fields is developed. Gauge symmetries are realized by involving the Stueckelberg fields. Realization of global conformal boost symmetries is obtained. Gauge invariant differential constraints for currents and shadow fields are obtained. AdS/CFT correspondence for currents and shadow fields and the respective normalizable and non-normalizable solutions of massless totally symmetric arbitrary spin AdS fields is studied. The bulk fields are considered in modified de Donder gauge that leads to decoupled equations of motion. We demonstrate that leftover on-shell gauge symmetries of bulk fields correspond to gauge symmetries of boundary currents and shadow fields, while the modified de Donder gauge conditions for bulk fields correspond to differential constraints for boundary conformal currents and shadow fields. Breaking conformal symmetries, we find interrelations between the gauge invariant formulation of the currents and shadow fields and the gauge invariant formulation of massive fields.

description: Zero-shot object detection (ZSD), the task that extends conventional detection models to detecting objects from unseen categories, has emerged as a new challenge in computer vision. Most existing approaches tackle the ZSD task with a strict mapping-transfer strategy, which may lead to suboptimal ZSD results: 1) the learning process of those models ignores the available unseen class information, and thus can be easily biased towards the seen categories; 2) the original visual feature space is not well-structured and lack of discriminative information. To address these issues, we develop a novel Semantics-Guided Contrastive Network for ZSD, named ContrastZSD, a detection framework that first brings contrastive learning mechanism into the realm of zero-shot detection. Particularly, ContrastZSD incorporates two semantics-guided contrastive learning subnets that contrast between region-category and region-region pairs respectively. The pairwise contrastive tasks take advantage of additional supervision signals derived from both ground truth label and pre-defined class similarity distribution. Under the guidance of those explicit semantic supervision, the model can learn more knowledge about unseen categories to avoid the bias problem to seen concepts, while optimizing the data structure of visual features to be more discriminative for better visual-semantic alignment. Extensive experiments are conducted on two popular benchmarks for ZSD, i.e., PASCAL VOC and MS COCO. Results show that our method outperforms the previous state-of-the-art on both ZSD and generalized ZSD tasks.

description: Phase space method provides a novel way for deducing qualitative features of nonlinear differential equations without actually solving them. The method is applied here for analyzing stability of circular orbits of test particles in various physically interesting environments. The approach is shown to work in a revealing way in Schwarzschild spacetime. All relevant conclusions about circular orbits in the Schwarzschild-de Sitter spacetime are shown to be remarkably encoded in a single parameter. The analysis in the rotating Kerr black hole readily exposes information as to how stability depends on the ratio of source rotation to particle angular momentum. As a wider application, it is exemplified how the analysis reveals useful information when applied to motion in a refractive medium, for instance, that of optical black holes.

Macroscopic modeling of strain-rate dependent energy dissipation of superelastic SMAs considering destabilization of martensitic lattice

description: Superelastic shape-memory alloys (SMAs) are unique smart materials with a considerable energy dissipation potential for dynamic loadings with varying strain-rates. The energy dissipation depends on the latent heat generated by the austenitic-martensitic transformation and the convection of that heat. Due to the thermomechanical coupling, the martensitic nucleation stress level and thus the propagation of martensitic phase fronts strongly depends on the material temperature. High strain-rate interferes with the release of the latent heat to the environment and determines quantity, position and propagation of martensitic transformation bands. Lastly, high strain-rate reduces the hysteresis surface. The propagation velocity and quantity of martensitic bands have an impact on martensitic phase stability. The degree of atomic disorder and accordingly the change in entropy influences the reverse phase transformation from martensite to austenite. In other words, the stability of the martensitic state affects the stress level of the reverse transformation. However, in phenomenological superelastic SMA models, which are used to simulate energy dissipation behavior, the effects of the rate-dependent entropy change are not considered in particular. To incorporate the rate-dependent entropy change, we improved a one-dimensional numerical model by introducing an additional control variable in the free energy formulation for solid-solid phase transformation of superelastic SMAs. In this model, the observed effects of the strain-rate on the reverse transformation are taken into account by calculating the rate-dependent entropy change. A comparison of the numerical results with the experimental data shows that the model calculates the dynamic superelastic hysteresis of SMAs more accurately.

description: This paper describes how automatically generated detailed kinetic mechanisms are obtained for the oxidation of alkanes and how these models could lead to a better understanding of autoignition and cool flame risks at elevated conditions. Examples of prediction of the occurrence of different autoignition phenomena, such as cool flames or two-stage ignitions are presented depending on the condition of pressure, temperature and mixture composition. Three compounds are treated, a light alkane, propane, and two heavier ones, n-heptane and n-decane.
