The nature of gameplay: a videogame classification

This paper is part of an experimental approach aimed to raise a videogames classification. Being inspired by the methodology that Propp[3] used for the classification of Russian fairy tales, we have cleared out recurrent diagrams within rules of videogames, named "Game Bricks". The combinations of these different bricks will allow us to represent a classification, in accordance to their rules, of all the videogames. In this article we will study the real nature of these bricks, especially the link they seem to have with two types of game rules: the rules that allow the player to "manipulate" the elements of the game and the rules defining the "goal" of the game. We will then study the relation between these bricks and the gameplay. These questions will help us to propose an hypothesis about the nature of gameplay.
Defining, Estimating and Using Credit Term Structures. Part 1: Consistent Valuation Measures

In this three-part series of papers, we argue that the conventional spread measures are not well defined for credit-risky bonds and introduce a set of credit term structures which correct for the biases associated with the strippable cash flow valuation assumption. We demonstrate that the resulting estimates are significantly more robust and remain meaningful even when applied to deeply distressed bonds. We also suggest a new definition of credit bond duration and convexity which remains consistent for distressed bonds and introduce new relative value measures for individual bonds in the context of sector or issuer credit curves, as well as for the basis between cash bonds and credit default swaps (CDS).
LTE Coverage Network Planning and Comparison with Different Propagation Models

Long Term Evolution (LTE) is the next step (fourth generation) mobile radio communication technology that succeeds the HSPA.3GPP standardization body. LTE is expected to be the most competitive radio technology in the future to provide high-data-rate transmission, low latency, improved service and reduced costs. This paper focuses on one of the basic steps in the LTE network planning, by employing LTE dimensioning process, such as link budget and planning, for uplink and downlink coverage, as well as categorization of simulated received signal strengths. Also, a comparison of different propagation models, used by ATDI software (free-space, Okumura / Hata / David, Stanford University Interim (SUI), COST-231 Hata and ITU -R 525/526 Deygout). The Okumura / Hata / David’s model showed the highest received power sensitivity (-61 dBm, at 3 km separation distance), while COST-231 Hata model shows the lowest sensitivity at same distance (-96 dBm). In this paper, ATDI planning LTE radio planning software platform has been used for estimating the coverage of UTM, which is a dense urban environment.
Evolution of mixing state of black carbon particles: Aircraft measurements over the western Pacific in March 2004

We report the evolution of the mixing state of black carbon (BC) particles in urban plumes measured by an airborne single particle soot photometer. The aircraft observations were conducted over the ocean near the coast of Japan in March 2004. The number fraction of coated BC particles with a core diameter of 180 nm increased from 0.35 to 0.63 within 12 hours (h), namely 2.3% h−1, after being emitted from the Nagoya urban area in Japan. BC particles with a core diameter of 250 nm increased at the slower rate of 1.0% h−1. The increase in coated BC particles was associated with increases in non‐sea salt sulfate and water‐soluble organic carbon by a factor of approximately two, indicating that these compounds contributed to the coating on the BC particles. These results give direct evidence that BC particles become internally mixed on a time scale of 12 h in urban plumes.
Parental cooperation in a changing climate: fluctuating environments predict shifts in care division

Aim: Parental care improves the survival of offspring and therefore has a major impact on reproductive success. It is increasingly recognized that coordinated biparental care is necessary to ensure the survival of offspring in hostile environments, but little is known about the influence of environmental fluctuations on parental cooperation. Assessing the impacts of environmental stochasticity, however, is essential for understanding how populations will respond to climate change and the associated increasing frequencies of extreme weather events. Here we investigate the influence of environmental stochasticity on biparental incubation in a cosmopolitan ground-nesting avian genus. Location: Global. Methods: We assembled data on biparental care in 36 plover populations (Charadrius spp.) from six continents, collected between 1981 and 2012. Using a space-for-time approach we investigate how average temperature, temperature stochasticity (i.e. year-to-year variation) and seasonal temperature variation during the breeding season influence parental cooperation during incubation. Results: We show that both average ambient temperature and its fluctuations influence parental cooperation during incubation. Male care relative to female care increases with both mean ambient temperature and temperature stochasticity. Local climatic conditions explain within-species population differences in parental cooperation, probably reflecting phenotypic plasticity of behaviour. Main conclusions: The degree of flexibility in parental cooperation is likely to mediate the impacts of climate change on the demography and reproductive behaviour of wild animal populations.
Allowable Bearing Capacity for Shallow Foundation in Eket Local Government Area, Akwa Ibom State, Southern Nigeria

P-wave and S-wave velocities were obtained from seismic refraction survey in the foundation layer of Eket, the study area. The Tezcan’s approach discussed extensively in the work was used in conjunction with the existing mathematical relations between elastic parameters and seismic refraction velocities for the study of foundation layers in the study area. Based on the results, the elastic constants, allowable bearing pressure/capacity, ultimate bearing capacity and other parameters in Table 1 were determined. The result shows that allowable bearing pressure increases with increase in shear modulus and shear wave velocity. The empirical relation between allowable bearing capacity and shear modulus shows that the allowable bearing capacity increases with depth. Comparing our findings with some ranges of safe allowable bearing capacities of similar non cohesive/granular soils in literatures, the second layer with allowable bearing capacity range of 72.56 - 206.63 kN·m −2 (average = 154.78 kN·m −2 ) has been considered to be the safe shallow engineering foundation in the study area. The empirical relations between allowable bearing capacities shear modulus and shear wave velocity, in conjunction with the inferred maps, which serve as our findings, will be used as guide in the location of foundations. The inferred ultimate and allowable capacities correlate maximally for the two shallow foundations penetrated by the seismic waves. This perfect correlation reflects the uniqueness of the method.
Floral biology and pistil receptivity of the drumstick tree (Moringa oleifera Lam.)

Drumstick ( Moringa oleifera Lam.) has a wide range of uses due to its high nutritional value and the high oil content of its seeds. Many aspects of its reproductive biology remain poorly understood. We investigated the floral morphology of drumstick, its stigma receptivity and the structural and cytochemical features of the stigma and style at different developmental stages. The inflorescences are panicles of hermaphroditic flowers, with a pistil consisting of one open-type stigma and a hollow stylar canal. Stigma receptivity was assayed based on pollen germination, pollen tube growth and fruit set following artificial pollination. Flowers at later developmental stages exhibited greater stigma receptivity, higher percentages of pollen germination and a higher fruit set than those in earlier stages. Enhanced stigma receptivity was associated with increased amounts of insoluble polysaccharides, lipids and proteins in the canal cells at later developmental stages. An ultrastructural study of the cells lining the canal indicated that they were secretory cells containing an enlarged endoplasmic reticulum, dictyosomes, mitochondria, plastids and ribosomes. Post-anthesis, these organelles exhibited degeneration at the end of the secretory phase. This study provides an important contribution to current knowledge of the anatomy and ultrastructure of the style and stigma in drumstick. https://doi.org/10.2298/ABS170205046Z Received: February 5, 2017; Revised: April 10, 2017; Accepted: May 8, 2017; Published online: November 20, 2017 How to cite this article: Zhang J, Lin M, Chen H, Zhu Q, Linh VN, Chen X.

Coordinated Design of PSS and Sliding Mode Based TCSC Controller for Enhancing Dynamic Stability of Power System

Coordination control of power system stabilizer (PSS) and Thyristor controlled series compensator (TCSC) gives a new and efficient design for the enhancing power system stability. PSS mainly improves the voltage regulation of the generatorand also enhance the dynamic performance of the power system. HoweverTCSC mainly vary the reactance of the transmission line and improves the stability limit of the power system. TCSC is also known as series compensator and has very fast response.In this paper Sliding mode control (SMC) based system is employed for the control of PSS and TCSC to improve the dynamic stability of a single machine infinite bus (SMIB) power system. System is tested in time domain MATLAB programming and the results show that the proposed scheme with Sliding mode control based system not only attenuate external disturbances on the system, but also power system dynamic performance improves. The results are compared with three different control schemes and also show that more quick response by the proposed method.
Relationship between barley yield and annual precipitation conditions

Barley grain yields and values of the effective drought index (EDI) in the critical period in terms of yield formation of spring barley in the Czech Republic were evaluated for the period 1975–2015. The EDI was calculated for four different experimental localities. The EDI is based on the calculation of effective precipitation using only daily precipitation. Both kind of the years with unfavourable precipitation conditions: 1976, 1984, 2004 and 2015, and the years with favourable precipitation conditions: 1975, 1979, 2006 and 2010 were determined. The historical grain yield range from the experimental localities for the barley was correlated with the values of the EDI at each locality for each decade (ten days). At most areas there were statistically significant relationships between grain yield and the EDI in different stages of vegetation; at some locations highly significant relationship. The statistically significant correlations (α = 0.01, α = 0.05) were found in 2nd, 4th, 6th, and 7th decade of vegetation.

Text Analytics Techniques in the Digital World: Word Embeddings and Bias

The proliferation of textual data in the form of online news articles and social media feeds has had an impact on the text analytics developments in recent years. Some of the challenges of natural language processing, understanding and generation have been successfully resolved and the results are applications such as AI personal assistants and bots. Word embeddings are an example of these successful solutions where unsupervised data-driven algorithms are used to understand concepts and relationships between words. This paper presents a description of word embedding algorithms, and a discussion on how bias in the training data can be captured, reproduced and even amplified by the algorithms.
EVALUATION OF THE RESULTS OF SUPERVISED SEGMENTATION USING A ROBUST TOOL: THE CASE OF ZERNIKE MOMENTS METHOD APPLIED TO MEDICAL IMAGING

Segmentation is considered as an essential step in a chain of image processing. We present here a state of the art on evaluation criteria for segmentation results in a supervised setting. First of all, we give an overview about the supervised evaluation criteria, and then we propose a new method based on Zernike moments. The main contribution of our method is the consideration of an existing texture in the image and the use of a single reference images for normal and displaced rotations. We used a database of 180 Magnetic Resonance Images (MRIs) that represent the different sections of the brain, 100 highly textured images, a database of 50 real images, and 5 synthetic images.
Simulation of high-average power windows for accelerator production of tritium

Development of a robust, high-average-power (210 kW, CW) microwave transmission line system for the Accelerator Production of Tritium (APT) facility is a stringent engineering and operational requirement. One key component in this RF transmission system is the vacuum barrier window. The requirement of high-power handling capability coupled to the desirability of good mean time to failure characteristics can be treated substantially with a set of microwave, thermal-structural, and Weibull analysis codes. In this paper, we examine realistic 3-D engineering models of the ceramic windows. We model the detailed cooling circuit and make use of accurate heat deposition models for the RF. This input and simulation detail is used to analyze the thermal- structural induced stresses in baseline coaxial window configurations. We also use a Weibull-distribution failure.
The Effect of de-Sitter Like Background on Increasing the Zero Point Budget of Dark Energy

During this work, using subtraction renormalization mechanism, zero point quantum fluctuations for bosonic scalar fields in a de-Sitter like background are investigated. By virtue of the observed value for spectral index, , for massive scalar field the best value for the first slow roll parameter, , is achieved. In addition, the energy density of vacuum quantum fluctuations for massless scalar field is obtained. The effects of these fluctuations on other components of the universe are studied. By solving the conservation equation, for some different examples, the energy density for different components of the universe is obtained. In the case which all components of the universe are in an interaction, the different dissipation functions, , are considered. The time evolution of shows that has the best agreement in comparison to observational data including CMB, BAO, and SNeIa data set.
Evaluation of Depression in HIV/AIDS Patients Refering to Behavioral Counselling Center of Imam Khomeini Hospital

HIV/AIDS because of its transmission methods has cultural, social and psychiatric impacts on patients especially in Islamic countries. We investigated depression frequency in an Iranian referral center for HIV/AIDS patients. All patients attending the counseling centre of Imam Khomeini Hospital during 2006 and 2007 who agreed to participate were enrolled. Depression was measured by Beck Depression Inventory-II (BDI-II) questionnaire. Patients with score 15 and above were considered depressed. 199 patients (27 female; age 37.9‏ ± 9.5) filled the questionnaire. BDI-II scores 13 and above and 15 and above were detected in 74/1% and 71/7% of patients, respectively. We observed statistically significant relationship between depression (as defined by BDI-II score > 15) and CD4 count, duration of diagnosed seropositivity, history of depression in the patients and his/her family, imprisonment, job status and education level. The relationship between depression and addiction was not statistically significant. The observed frequency of depression in our study (74%) is one of the highest ever reported. we recommend regular psychiatric visits for these patients in Islamic countries.
Some Nonlinear Gronwall-Bellman-Gamidov Integral Inequalities and Their Weakly Singular Analogues with Applications

Some Gronwall-Bellman-Gamidov type integral inequalities with power nonlinearity and their weakly singular analogues are established, which can give the explicit bound on solution of a class of nonlinear fractional integral equations. An example is presented to show the application for the qualitative study of solutions of a fractional integral equation with the Riemann-Liouville fractional operator.
Pushing amplitude equations far from threshold: application to the supercritical Hopf bifurcation in the cylinder wake

The purpose of this review article is to push amplitude equations as far as possible from threshold. We focus on the Stuart–Landau amplitude equation describing the supercritical Hopf bifurcation of the flow in the wake of a cylinder for critical Reynolds number Re c ≈ 46 . After having reviewed Stuart's weakly nonlinear multiple-scale expansion method, we first demonstrate the crucial importance of the choice of the critical parameter. For the wake behind a cylinder considered in this paper, choosing ϵ 2 = Re c − 1 − Re − 1 instead of ϵ ′ 2 = Re − Re c Re c 2 considerably improves the prediction of the Landau equation. Although Sipp and Lebedev (2007 J. Fluid Mech 593 333–58) correctly identified the adequate bifurcation parameter ϵ, they have plotted their results adding an additional linearization, which amounts to using ϵ ′ as approximation to ϵ. We then illustrate the risks of calculating ‘running’ Landau constants by projection formulas at arbitrary values of the control parameter. For the cylinder wake case, this scheme breaks down and diverges close to Re ≈ 100 . We propose an interpretation based on the progressive loss of the non-resonant compatibility condition, which is the cornerstone of Stuart's multiple-scale expansion method. We then briefly review a self-consistent model recently introduced in the literature and demonstrate a link between its properties and the above-mentioned failure.
Résumé Une recherche de synthèse sur les attitudes du personnel infirmier à l ’ égard des lesbiennes , gais , bisexuels et transgenres

Un nombre croissant d’études suggèrent que les lesbiennes, gais, bisexuels et transgenres (LGBT) vivent des disparités importantes en matière de santé par rapport aux hétérosexuels. Les raisons de cette situation sont complexes et multifactorielles. Un domaine de la recherche sur ce sujet examine en particulier les attitudes négatives réelles ou perçues des fournisseurs de soins de santé. La présente recherche de synthèse a comporté l’évaluation critique et la synthétisation des données tirées de 17 articles traitant des attitudes des infirmières et des infirmiers envers les patients LBGT. Toutes les études analysées faisaient état de certaines attitudes négatives. La littérature révèle toutefois des limites importantes, notamment le manque d’études bien conçues et d’études qualitatives; l’utilisation inégale d’instruments validés et fiables; et le manque de mesures examinant les attitudes envers les lesbiennes, bisexuels et transgenres. Plus de connaissances dans ce domaine pourraient permettre la mise en œuvre d’interventions pour améliorer la compétence culturelle du personnel infirmier; l’allocation de ressources à la recherche en sciences infirmières, à l’éducation et aux services liés à la santé des personnes LGBT; et l’inclusion de plus de contenu LGBT dans les programmes d’études en sciences infirmières.
