A fuzzy portfolio trading system in the foreign exchange market based on technical analysis Conference

Technical trading rules are extensively used by foreign exchange (forex) traders. Despite the essential need to the forex diversification, it is not addressed by academic researches to generate forex portfolio trading systems based on technical indices. This paper aims to develop an interpretable and accurate Takagi-Sugeno-Kang (TSK) system for forex portfolio trading. The system uses technical indices of the forex rates and delivers the preferred portfolio composition among multiple foreign currencies. The proposed model considers the transaction cost and trading risk, which are the two important factors in the high frequency trading strategies. The proposed model was implemented to develop a trading system for portfolio trading among the five of the most traded currencies in the Tehran forex market. Four experiments were designed to examine the performance of the proposed model in different market trends, in terms of the portfolio return and risk adjusted return. According to the experimental results, the proposed model is able to extract profitable portfolio trading systems in this market, especially when the market is in the downward trend.
Financial Market Dynamics in an Enlarged European Union

This paper provides evidence of integration in European equity and bond markets over the period January 2, 1997 to October 1, 2006. Our focus is to examine time-varying correlation dynamics in Euro-area, Central European (CE) and Balkan financial markets, modifying the asymmetric generalized dynamic conditional correlation (AG-DCC) model developed by Cappiello, Engle and Sheppard (Journal of Financial Econometrics, 2006). Using structural breaks, we identify the optimal time decay where financial markets share highest comovement. The results show an increase in the level of dependence during the period of the internet bubble collapse (2000), the Balkan countries start formally discussions to join European Union (2000), the introduction of Euro banknotes and coins (2002) and the entry of CE countries in EU (2004). The CE European and Balkan countries become gradually more integrated with the EMU countries, which is consistent with the interpretation that these countries may be expected to join the Euro in the future.
Causes and Consequences of Grade Repetition: Evidence from Brazil

Even though the problem of grade repetition is high on the policy agenda of virtually every developing country, extremely little is known about either the causes or the educational effects of repetition. The general concern about grade repetition derives from the budgetary and social implications of having large numbers of repeaters taking up scarce positions in schools. This concern notwithstanding, fundamental disagreements about the nature of the problem have clearly inhibited the development of sensible policies. This research, relying on unique panel data for students in northeast Brazil, considers how the schooling system and individual students interact in determining enrollment patterns in primary schools. This investigation into underlying student and school behavior lays the groundwork for analysis of alternative policies. Discussions of repetition are often subsumed in larger discussions of "wastage"-the combination of repetition and dropout rates. ' This combination is unfortunate in many ways because the two phenomena are quite different in both their causes and their consequences. Nevertheless, they tend to be intertwined both in the data and estimation and in the policy debate. Indeed, the combination of high dropout and repetition rates has been identified as one of the main failures of the Brazilian education system, in part because the rates appear above those in other countries. A brief review of the available data and more general issues sets the stage for the analysis of grade repetition. Reflecting the low level of information about the issues, disagreement arises immediately about the magnitude and form of the wastage problem. Commonly available and cited data reveal important discrepancies even among estimates of the level of aggregate wastage and its
Giant lacustrine pockmarks with subaqueous groundwater discharge and subsurface sediment mobilization

Subsurface fluid flow in oceans and lakes affects bathymetric morphology, sediment distribution, and water composition. We present newly discovered giant lacustrine pockmarks in Lake Neuchâtel (up to 160 m diameter and 30 m deep) that rank among the largest known pockmarks in lakes. Our multidisciplinary study reveals ~60 m of suspended sediment inside a pockmark. The sediment suspension is 2.6° warmer and isotopically lighter in δ18OH2O by 1.5‰ than the ambient lake water, documenting currently active fluid flow by karstic groundwater discharge from the Jura Mountain front into the Swiss Plateau hydrological system. Strikingly, the levees of the pockmarks comprise subsurface sediment mobilization deposits representing episodic phases of sediment expulsion during the past. They strongly resemble subsurface fluid flow features in the marine realm. Comparable processes are expected to also be relevant for other carbonate‐dominated mountain front ranges, where karstic groundwater discharges into lacustrine or marine settings.
CHS: Small: Collaborative Research: Community Success: Advancing Knowledge of Collaborative Organization Through Large-Scale Empirical Comparison of Peer Production Systems

Peer production – the form of community-based online collaboration used to create public information goods like Wikipedia and Linux – has transformed knowledge production, management, and innovation (Benkler, 2006; Benkler et al., 2015). Inspired by large, successful peer production projects, thousands of wikis and free/libre open source software (FLOSS) projects are started each year. The vast majority of these efforts – and even those that build sustainable and useful information goods – never become more than the work of a single individual (Healy and Schussman, 2003; Schweik and English, 2012).
A Class of Hazard Rate Mixtures for Combining Survival Data From Different Experiments

Mixture models for hazard rate functions are widely used tools for addressing the statistical analysis of survival data subject to a censoring mechanism. The present article introduced a new class of vectors of random hazard rate functions that are expressed as kernel mixtures of dependent completely random measures. This leads to define dependent nonparametric prior processes that are suitably tailored to draw inferences in the presence of heterogenous observations. Besides its flexibility, an important appealing feature of our proposal is analytical tractability: we are, indeed, able to determine some relevant distributional properties and a posterior characterization that is also the key for devising an efficient Markov chain Monte Carlo sampler. For illustrative purposes, we specialize our general results to a class of dependent extended gamma processes. We finally display a few numerical examples, including both simulated and real two-sample datasets: these allow us to identify the effect of a borrowing strength phenomenon and provide evidence of the effectiveness of the prior to deal with datasets for which the proportional hazards assumption does not hold true. Supplementary materials for this article are available online.
Permanent fast flow versus cyclic surge behaviour: numerical simulations of the Austfonna ice cap, Svalbard

Abstract A large part of the ice flux within ice caps occurs through spatially limited fast-flowing units. Some of them permanently maintain fast flow, whereas others operate in an oscillatory mode, characterized by short-lived active phases followed by long quiescent phases. This surge-type behaviour results from intrinsic rather than external factors, thus complicating estimates of glacier response to climate change. Here we present numerical model results from Austfonna, an ice cap on Svalbard that comprises several surge-type basins. Previous studies have suggested a thermally controlled soft-bed surge mechanism for Svalbard. We systematically change the parameters that govern the nature of basal motion and thereby control the transition between permanent and oscillatory fast flow. Surge-type behaviour is realized by a relatively abrupt onset of basal sliding when basal temperatures approach the pressure-melting point and enhanced sliding of marine grounded ice. Irrespective of the dynamic regime, the absence of considerable volumes of temperate ice, both in the observed and simulated ice cap, indicates that fast flow is accomplished by basal motion over a temperate bed. Given an idealized present-day climate, the equilibrium ice-cap size varies significantly, depending on the chosen parameters.
Elastic anisotropy of D″ predicted from global models of mantle flow

In order to test the hypothesis that seismic anisotropy in the lowermost mantle is caused by the development of a post‐perovskite lattice preferred orientation, and that anisotropy can thus be used as a probe of the dynamics of the mantle's lower boundary layer, an integrated model of texture generation in D″ is developed. This is used to predict the elastic anisotropy of the lowermost mantle as probed by global anisotropic tomographic inversions. The model combines the current 3D mantle flow field with simulations of the deformation of post‐perovskite polycrystalline aggregates. Different descriptions of single crystal plasticity can lead to model results which are anti‐correlated to each other. In models where post‐perovskite deformation is accommodated by dislocations moving on (010) or (100), patterns of anisotropy are approximately correlated with the results of tomographic inversions. On the other hand, in models where dislocations move on (001) patterns of anisotropy are nearly anti‐correlated with tomographic inversions. If all the seismic anisotropy in D″ extracted from global anisotropic inversions is due to the presence of a lattice preferred orientation in post‐perovskite in the lowermost mantle, and if the results of the tomographic inversions are not strongly biased by the sampling geometries, these results suggest that, in contrast to ideas based on the 1D anisotropic signal, deformation of post‐perovskite in the lowermost mantle may be accommodated by dislocations moving on (010) or (100). Alternatively, a significant portion of the anisotropic signal may be caused by mechanisms other than the alignment of post‐perovskite crystals.
Changes in Biochemical, Sensory and Microbiological Quality Indices of Common Sole (Solea solea) from the Mediterranean Sea, During Ice Storage

The quality of wild common sole (Solea solea) stored in ice was investigated by chemical (K value, biogenic amines, protein degradation (SDS and SDS-PAGE), pH, peroxide value (PV), free fatty acids (FFA), total volatile basic nitrogen (TVB-N), tiobarbituric acid (TBA) analyses), sensory (raw and cooked fish) and microbiological methods. The quality of common sole decreased on day 16 (fair qualityB) and they were no longer acceptable on day 20 (unacceptable quality-C). When common sole were considered as fair quality (B) by assessors on ~16-18 days, the average K value was ≥ 80%. Among the investigated biogenic amines, histamine was not detected. No major change in the protein profiles of common sole was observed. Sensory, microbial and biochemical results revealed that the shelf life of common sole was approximately ~16-18 days. Among the chemical parameters, the most consistent indicator to measure the change in freshness was K value that showed linear response with storage time.
Economic Vulnerability and Severity of Debt Problems: An Analysis of the Irish EU-SILC 2008

In this paper, using Ireland, where debt issues are of particular salience as a test case, we seek to understand the extent to which the measures currently employed as national indicators of poverty and social exclusion succeed in capturing over-indebtedness and, more broadly, severity of debt problems. Our analysis reveals a clear gradient with predictive ability increasing sharply as one moves from 'at risk of poverty' to consistent poverty and finally economic vulnerability indicators. In relation to debt problems, the key distinction is between the just under one in five households defined as economically vulnerable and all others. Financial exclusion, relating to access to a bank account and a credit card, was found to increase debt levels. However, such effects were modest. The impact of economic vulnerability seems to be largely a consequence of its relationship to a wide range of socio-economic attributes and circumstances. The manner in which a potential debt crisis unfolds will be shaped by the broader socio-economic structuring of life-chances. Any attempt to respond to such problems by concentrating on household behaviour or, indeed, triggering factors without taking the wider social structuring of economic vulnerability is likely to be both seriously misguided and largely ineffective.
The Use of Nutrition to Increase Sheep Performance

In many production systems, sheep performance has increased over time as farmers have aimed to improve profitability. However, systems based on grasses only can be insufficient to allow for high levels of animal performance. This has resulted in increased interest in the use of specialist crops and supplements. There is now information available for farmers on the potential performance levels that can be achieved using these alternative feed sources. However, farmers need to examine carefully the cost effectiveness of these, before using them. Further it is possible that in the future management guidelines will be developed in pregnancy for farmers to utilise to increase the performance of future generations. Further work is required to determine if consistent responses can be found. DOI: 10.15528/2176-4158/rcpa.v15n1p63-76
Electromyography Signals Processing for Gait Phase Recognition

Gait phase recognition systems are widely used in medicine to control devices aimed at restoration of patients’ motor functions and have an increasing interest in scientific society. Use of electromyography as a source of information for such systems gives considerable advantages in comparison with other data sources at the cost of complex signal processing needed. In this paper, the author outlines these advantages and suggests a method that uses discrete wavelet transform to retrieve muscle activity shape and a novel double-threshold detector to find the regions of activity. Then a robust statistical treatment is performed following a dimensionality reduction. As a result, a set of classification objects is retrieved that are suitable for further use in various clustering and classification techniques. The introduced method was tested in the Movement Physiology Laboratory of I. P. Pavlov Institute of Physiology, Russian Academy of Sciences and proved its applicability on real electromyography data.
The Relationship between Blood Group Type and Cutaneous Leishmaniasis in Aleppo

Background: Cutaneous leishmaniasis (CL) is a health problem, especially in tropical and subtropical countries. In spite of new scientific developments in recent years, several questions related to this disease have been raised that have still no answer. This study was performed to investigate the relationship between blood group type and CL among Syrian patients. Methods: of 100 suspected CL patients referred to the Aleppo University Hospital Clinic, 60 patients were randomly selected and after the diagnosis of CL was made by tissue smear and skin biopsy their blood groups and RH factors were determined and recorded in a questionnaire. Similarly 600 volunteers referring to the Blood transfusion center were randomly selected and their blood group and RH factor were determined with a similar method. Data were analyzed by using Chi-Square test. Results: There were 38 males and 22 females among CL patients. There was no significant difference between the case and control groups in regard to the frequency of blood groups and RH . In both the CL and control groups, the highest percentage was of blood group O ve and the lowest of blood group AB-ve. Conclusions: Our results showed that the blood group was not a risk factor in the occurrence of CL. The ABO-Rh blood groups were not associated with the occurrence of CL in Syrian patients. As CL disease is becoming more complex, it is necessary to conduct further clinical basic studies in endemic areas.
Three‐Player Trust Game with Insider Communication

We examine behavior in a three-player trust game in which the first player may invest in the second and the second may invest in the third. Any amount sent from one player to the next is tripled. The third player decides the final allocation among three players. The baseline treatment with no communication shows that the first and second players send significant amounts and the third player reciprocates. Allowing insider communication between the second and the third players increases cooperation between these two. Interestingly, there is an external effect of insider communication: the first player who is outside communication sends 54% more and receives 289% more than in the baseline treatment. As a result, insider communication increases efficiency from 44% to 68%.
Diabetes Mellitus, Hypertension & Associated Factor’s among students of Jazan in the Kingdom of Saudi Arabia

Background : Health-related issues has been one of the major factor of concern for the death since the last three decades in Saudi Arabia which includes diabetes mellitus, hypertension and other associated factors are considered as major risk factors. The investigation on the prevalence of Diabetes, Hypertension and associated factors among students of Jazan, Saudi Arabia is an alarm for the hidden possible health threat among the students in the younger age. Methods : The study aimed to assess the prevalence of Diabetes, Hypertension and associated factors in fifty students of Jazan in Kingdom of Saudi Arabia. Data were collected through interview using a structured questionnaire followed by clinical examination. Clinical practice methods were followed to estimate Cholesterol, Body Mass Index (BMI), weight, Diabetes and Hypertension from the sample. Results : A high percentage of participants i.e. 70% are pre diabetes, which is partly due to a more sedentary lifestyle and smoking and weight gain. 62% of participants reported no physical exercise in daily life. Habit of smoking is present among 44% of the participants over weight and obesity showed as 24% and 16% respectively. The high blood pressure among the participants was 36% and 64% were prehypertensive. Obesity and weight assessed by using Body Mass Index. The result showed 52% among the participants were in normal weight, 24% were overweight and 16% were obese. CONCLUSION: The prevalence of Smoking, physical inactivity, obesity and cholesterol level were associated with the risk of Pre-hypertension, hypertension, pre-diabetics and diabetics.

Geometric and temporal evolution of an extensional detachment fault, Hohhot metamorphic core complex, Inner Mongolia, China

The Early Cretaceous Hohhot metamorphic core complex and its master Hohhot detachment fault are ;400 km west of Beijing in the Daqing Shan (Mountains) of Inner Mongolia. The complex developed across the east-trending Yinshan fold-and-thrust belt within ,4 m.y. following cessation of thrusting ca. 125 Ma (see note added in proof in main text). Postcontractional extension was initiated within a mid-crustal zone of mylonitic and ductile shear that was in part controlled by Carboniferous(? ) strata sandwiched between its Proterozoic and Archean crystalline basement and an overlying thrust sheet of similar crystalline rocks. The Hohhot detachment fault appears to have rooted into deep, kinematically active levels of the mid-crustal shear zone. Higher, inactive levels of the mylonitic section were transected by the fault and carried upward in its footwall. Geometries of the footwall mylonitic rocks indicate localized ramp-flat geometries of the fault within and across them. The crosscut top of the mylonitic sequence defines a mylonitic front that departs from the gently south dipping detachment fault and dips northward into its footwall. Early Cretaceous extension was widespread elsewhere in northern China, and was particularly pronounced in the Yunmeng Shan core complex north of Beijing. The gravitational collapse of orogenically thickened crust acting in concert with localized centers of deep-seated plutonism appear to have led to the development of isolated metamorphic core complexes within a broad region of more distributed extensional deformation.
Perinatal Exposure to Sodium Fluoride with Emphasis on Territorial Aggression , Sexual Behaviour and Fertility in Male Rats

Territorial aggression, sexual behaviour and fertility parameters were evaluated at adulthood of male rats previously exposed to different concentrations of sodium fluoride (Na-F) at their gestation, lactation and postweaning period till maturation. Sixty weanling male Wistar rats were received Na-F via their dams from second trimester of their pregnancy onward till weaning at 30 days of age at one of three different concentrations; 0, 50 and 100 ppm, 20 pups for each dose. Na-F was then administered in drinking water, at the same doses, to the three experimental groups throughout the course of the study till completing all investigations. Na-F treatment significantly diminished territorial aggressive behaviour parameters in adult male rats as indicated by reduced lateralization, boxing bouts, fighting as well as ventral presenting postures compared with controls. Likewise, a significant decline in sexual behaviour was also noted for Na-F-exposed rats, where latencies to first mount, intromission and ejaculation were significantly prolonged, and notably for the higher incorporated dose. Moreover, a significant decrease was evident for frequencies of mounts, intromissions and ejaculations when Na-F was given to males compared to their untreated counterparts. Higher post-ejaculatory intervals were observed with Na-F group, particularly at high dose. Compared to control group, high Na-F-treated rats displayed a significant inhibited profile of fertility as reflected in reduced number of impregnated females, implantations as well as viable fetuses, along with increased number of resorptions. Relative weights of reproductive organs were also lessened in Na-Fadministered males. Histopathological examination showed degenerative changes in testes, seminal vesicles and prostate gland of Na-F-exposed males with varied degree of severity according to incorporated dose. Our study clearly signifies the adverse effect of fluoride on territorial aggression, sexual performance with inhibited fertility in adult male rats. [Heba S. El-lethey, Mervat M. Kamel, Iman B.

When does deep multi-task learning work for loosely related document classification tasks?

This work aims to contribute to our understanding of when multi-task learning through parameter sharing in deep neural networks leads to improvements over single-task learning. We focus on the setting of learning from loosely related tasks, for which no theoretical guarantees exist. We therefore approach the question empirically, studying which properties of datasets and single-task learning characteristics correlate with improvements from multi-task learning. We are the first to study this in a text classification setting and across more than 500 different task pairs.
