Performance Metrics for Algorithmic Traders

Portfolio traders may split large orders into smaller orders scheduled over time to reduce price impact. Since handling many orders is cumbersome, these smaller orders are often traded in an automated (“algorithmic”) manner. We propose metrics using these orders to help measure various trading-related skills with low noise. Managers may use these metrics to assess how separate parts of the trading process contribute execution, market timing, and order scheduling skills versus luck. These metrics could save 4 basis points in cost per trade yielding a 15% reduction in expenses and saving $7.3 billion annually for US-domiciled equity mutual funds alone. The metrics also allow recovery of parameters for a price impact model with lasting and ephemeral effects. Some metrics may help evaluate external intermediaries, test for possible front-running, and indicate sloppy or overly passive trading.
Experimental Study on Optimization of Thermal Properties of Groundnut Shell Particle Reinforced Polymer Composites

Recently, thermoplastic and thermoset polymers are combined with natural fillers to produce the composites, which possess better strength and good resistance to fracture. Due to an excellent property profile, these composites find wide applications in packaging, building and civil engineering fields. The present work aims to elucidate the optimization of thermal properties such as thermal conductivity, linear thermal expansion and specific heat of groundnut shell particles reinforced polymer composite materials. The composite specimens were prepared with different weight percentages of randomly distributed groundnut shell particles in polymer matrix. The experiments were planned as per Taguchi L9orthogonal array. The analysis of means (ANOM) was performed to determine the optimal parameter levels and analysis of variance (ANOVA) was employed to identify the level of importance of the parameters on each of the properties. TGA and DSC analyses were also carried out to ascertain the thermal stability of these composites. The results revealed that using groundnut shell particles as reinforcement for polymer matrix could successfully develop beneficial composites and can be used for thermal applications.

Abstract—A compact open-loop resonator bandpass filter with suppression of the second and the third harmonics is demonstrated in this paper. This novel filter is based on a Tri-Section SIR to achieve size minimization and suppressed spurious response. The simulations and measurements of a 0.9 GHz prototype bandpass filter are presented. The measured results agree well with simulation and calculation.
Sex differences in intrusive memories following trauma

Background A key mechanism thought to underlie Posttraumatic Stress Disorder (PTSD) is enhanced emotional memory consolidation. Recent evidence in healthy controls revealed that women have greater negative memory consolidation following stress relative to men. This study examined emotional memory consolidation in women and men with PTSD, and in trauma-exposed and non-trauma controls to test the hypothesis that emotionally negative memory consolidation would be greater in women with PTSD. Method One hundred and forty-seven men and women (47 with PTSD, 49 trauma-exposed controls, and 51 non-trauma controls) completed an emotional memory task where they looked at negative, neutral and positive images from the International Affective Picture System (IAPS). Delayed recall and an intrusive memory diary were completed two days later. Results Women displayed greater recall, and reported more negative intrusive memories than men. A gender x group interaction effect showed that both women with PTSD and trauma-exposed women reported more intrusive memories than women without trauma exposure or men. Conclusion This study provided preliminary evidence of sex differences in intrusive memories in those with PTSD as well as those with a history of trauma exposure. Future research should include measures of sex hormones to further examine sex differences on memory consolidation in the context of trauma exposure and PTSD.
George Town World Heritage Site: What We Have and What We Sell?

In the new era of technology, internet turns to be one of the main sources of information, since it is considered cheaper and easier to use. Hence in tourism, two main pull factors influencing potential tourist to visit a destination are recognized as nature and culture which a destination offers. The acceptance of culture as one of the important factors in tourists’ motivation, heritage sites become popular in many countries especially those which are nominated as world heritage sites. This paper is to analyze the condition of available online information about George Town world heritage spots (Penang, Malaysia). As far as heritage is one of the products of tourism and tourism, on the other hand, is a big help for sustainability of heritage sites, providing sufficient information about tourism heritage sites as a promotional key is very important. Top ten tourism websites were chosen and content analysis was performed to find the current situation of those websites. By recognizing heritage as tangible and intangible, the result shows that although the intangible heritages need more concern in sustainability matter, but the information about them are not as complete as the tangible ones. Lack of proper information was seen in most websites and the focus of information was more on tangible heritage and among intangible heritage, the main focus was on food. To support the result of analysis, in-dept interviews were conducted by couple of heritage offices in the city. The main reason behind the lack of sufficient information about intangible heritage seems to be the lack of complete list of them and moreover, promoting this division of heritage needs negotiation with the local residence involving in those activities. The paper suggests providing a complete list of George Town world heritage as far as some of them are disappearing lately, and keeping this valuable world heritage sustainable for next generation needs detailed study and completing the list as soon as possible. In this regard those intangible heritages which are in hazard of disappearing can be maintained by the effort of key holders of the field. Moreover, providing the mentioned list helps the information providers, especially related websites to focus equally on tangible and intangible George Town world heritage.
A Study of Implementation for Visualizing 3 Dimension Content Generation using Index

Mobile device, one of typical devices in ubiquitous environment, is received attention owing to portability. In these days, technical researches on a kind of the device are focusing on applications of smart phone. For example, the techniques using geographical position and applied instances such as augmented reality techniques are gradually increasing. That makes data processing important. Mobile application services for users also require various application techniques based on moving objects. In addition, they require the techniques that processed data are needed to be shown in visualization. However, this is reality that it lacks of showing visualization works to improve the understanding of thing what it is. To reduce or solve the problems, in this paper we show the results to implement the R tree based 3 dimension index architecture in visualization. Further, we implemented and present creating objects, showing in 3D for the objects, catching spatial position on a node map through mini map function and improving the understanding of R tree by visualizing.
Pruning bad quality causal links in sequential satisfying planning

Although current sequential satisficing planners are able to find solutions for a wide range of problems, the generation of good quality plans still remains a challenge. Anytime planners, which use the cost of the last plan found to prune the next search episodes, have shown useful to improve the quality of the solutions. With this in mind this paper proposes a method that exploits the solutions found by an anytime planner to improve the quality of the subsequent ones. The method extracts a set of causal links from the first plans, the plans with worse quality, and creates a more constrained definition of the planning task that rejects the creation of these causal links. The performance of the proposed method is evaluated in domains in which optimization is particularly challenging.
What in the World Makes Recursion so Easy to Learn? A Statistical Account of the Staged Input Effect on Learning a Center-Embedded Structure in Artificial Grammar Learning (AGL)

In an artificial grammar learning study, Lai & Poletiek (2011) found that human participants could learn a center-embedded recursive grammar only if the input during training was presented in a staged fashion. Previous studies on artificial grammar learning, with randomly ordered input, failed to demonstrate learning of such a center-embedded structure. In the account proposed here, the staged input effect is explained by a fine-tuned match between the statistical characteristics of the incrementally organized input and the development of human cognitive learning over time, from low level, linear associative, to hierarchical processing of long distance dependencies. Interestingly, staged input seems to be effective only for learning hierarchical structures, and unhelpful for learning linear grammars.
Antioxidant properties of cultivated edible mushroom (Agaricus bisporus) in Kenya

Antioxidant activities and phytochemical compounds of ethanol and hot water extracts of Agaricus bisporus species fruiting body and mycelia cultivated in Kenya were spectophotometrically determined and evaluated. The total antioxidant activity was analysed using 1,1-diphenyl-2-picrylhydrazil, hydroxyl, superoxide radical scavenging and reducing power assays, while phytochemicals were assayed through calorimetric assays. Total phenolic, β-carotene, lycopene, flavanoid and ascorbic acid composition of A. bisporus extracts was analysed by calometric assays and found to contain 40.26 to 4.61 mg/g, 48.99 to 2.86 mg/g, 67.82 to 11.87 mg/g, 93.8 to17.2 mg/g and 11.62 to 10.22 mg/g) respectively. The mineral elemental analysis done using energy dispenser x-ray fluorescence (EDXRF) analytical method revealed that the samples contain zinc (42.9 mg/l), iron (33 to 48.5 mg/l), copper (18 to 24 mg/l) and manganese (7.5 to 9 mg/l). Generally, the mycelium extracts were more effective radical scavengers than the fruiting bodies. Due to the above characteristics, A. bisporus mushroom could be considered a food complement with antioxidative activity in the diet for the health benefits they present. Their effectiveness was also evaluated by their EC50 values through interpolation from linear regression analysis of their respective data. Key words: Button mushroom (Agaricus bisporus), edible mushroom, antioxidant, reducing power, scavenging ability, phytochemicals.
19F-nuclear magnetic resonance spectroscopy as a tool to investigate host-guest complexation of some antidepressant drugs with natural and modified cyclodextrins

Purpose: 19 F-Nuclear magnetic resonance spectroscopy ( 19 F-NMR) was used to study host-guest complexation of three fluorine containing antidepressant drugs, viz, fluoxetine hydrochloride, citalopram hydrobromide and fluvoxamine maleate, with various cyclodextrins (CD), including α-, β-cyclodextrin, methylated α-cyclodextrin (M-α-CD), diamino derivative of methylated α-cyclodextrin, (DAM-α-CD) and tetramino derivative of methylated α-cyclodextrin (TAM-α-CD). Methods: Using the mole ratio method, a 1:1 stoichiometry was determined for the resulting inclusion complexes. 19 F chemical shifts were used to determine the formation constant of the complexes. Experiments were performed with solutions containing 0.001 M drug and various concentrations of CDs. NMR data were plotted as 19 F chemical shift versus CD/drug mole ratio, and fitted using the nonlinear least-squares curve fitting program, KINFIT, to obtain the formation constant of CD-drug complex. Molecular modeling (MM) calculations were used to predict the geometry of the complex of fluvoxamine and β-CD. Molecular modeling studies were performed in vacuum phase, employing empirical force fields and semi-empirical quantum theory using AM1 Hamiltonian. Results: Complex formation caused separation of the fluorine peaks that can be assigned to the two enantiomers of fluoxetine hydrochloride. Molecular modeling data suggest that fluvoxamine/β-CD inclusion complexes have a 1:1 stoichiometry and that the CF3-substituted ring of fluvoxamine is embedded in the cavity of β-CD, indicating a good agreement between molecular modeling calculation and experimental data (NMR data). Conclusion: One-dimensional 19 F-NMR is a fast and convenient method for the determination of complex stoichiometry and complexation constants of natural and modified CDs and fluorinated drugs. Keywords: Antidepressant drugs, Cyclodextrins, Complexation, Inclusion complex, Formation constant, 19 F-NMR
Business Communication In Function Of Improving The Organizational Culture Of The Company

This paper presents an action research conducted in function of proving the connection between effective communication and organizational culture. Bearing in mind that we communicate daily wherever we are, including our work places, we can conclude that communication is a part of our daily behavior. It is precisely our daily behavior that shows us our habits, norms, standpoints and value systems; the ones we have accepted and through which we manifest our behavior. Recognizing organizational culture within these frames is the challenge that this paper has taken on and it presents a successful attempt of proving the connection between business communication and organizational culture. The research has been conducted with a total of 282 examinees from the first ten of the top 200 organizations for 2013 in the Republic of Macedonia. The same has proven the general hypothesis about the connection between business communication and organizational culture.
Instrumental Variables Regressions with Uncertain Exclusion Restrictions

The identification of structural parameters in the linear instrumental variables (IV) model is typically achieved by imposing the prior identifying assumption that the error term in the structural equation of interest is orthogonal to the instruments. Since this exclusion restriction is fundamentally untestable, there often are legitimate doubts about the extent to which the exclusion restriction holds. In this paper I illustrate the effects of such prior uncertainty about the validity of the exclusion restriction on inferences based on linear IV models. In particular, I provide a mapping from prior uncertainty about the exclusion restriction into increased uncertainty about parameters of interest. Moderate prior uncertainty about exclusion restrictions can lead to a substantial loss of precision in estimates of structural parameters. This loss of precision is relatively more important in situations where IV estimates appear to be more precise, for example in larger samples or with stronger instruments. I illustrate these points using several prominent recent empirical papers that use linear IV models. An accompanying electronic table allows users to readily explore the robustness of inferences to uncertainty about the exclusion restriction in their particular applications.
Irreversible plasma and muscle protein oxidation and physical exercise

Abstract The imbalance between the reactive oxygen (ROS) and nitrogen (RNS) species production and their handling by the antioxidant machinery (low molecular weight antioxidant molecules and antioxidant enzymes), also known as oxidative stress, is a condition caused by physiological and pathological processes. Moreover, oxidative stress may be due to an overproduction of free radicals during physical exercise. Excess of radical species leads to the modification of molecules, such as proteins – the most susceptible to oxidative modification – lipids and DNA. With regard to the oxidation of proteins, carbonylation is an oxidative modification that has been widely described. Several studies have detected changes in the total amount of protein carbonyls following different types of physical exercise, but only few of these identified the specific amino acidic residues targets of such oxidation. In this respect, proteomic approaches allow to identify the proteins susceptible to carbonylation and in many cases, it is also possible to identify the specific protein carbonylation sites. This review focuses on the role of protein oxidation, and specifically carbonyl formation, for plasma and skeletal muscle proteins, following different types of physical exercise performed at different intensities. Furthermore, we focused on the proteomic strategies used to identify the specific protein targets of carbonylation. Overall, our analysis suggests that regular physical activity promotes a protection against protein carbonylation, due to the activation of the antioxidant defence or of the turnover of protein carbonyls. However, we can conclude that from the comprehensive bibliography analysed, there is no clearly defined specific physiological role about this post-translational modification of proteins.
The relationship between dental fear and sociodemographic variables.

Purpose: The aim of the study was to investigate the effects of age, gender and educational level on the dental anxiety of patients admitted to the Department of Restorative Dentistry and Endodontics at Erciyes Universitys Faculty of Dentistry. Patients and Methods: In the study, 324 patients were asked to complete a questionnaire. The survey consisted of two sections. The first section requested participants sociodemographic information such as including age, gender and educational level. The second section consisted of the Modified Dental Anxiety Scale (MDAS). Results: No correlation was found between age and MDAS (r= -0.011, p=0.844). Females tend to be more anxious than males (p< 0.001). The results showed that educational level had no significant effect on dental anxiety (p=0.837). Conclusions: In this study, it was observed that dental anxiety was not affected by age or education level, and that the dental anxiety levels of females were higher than males.
Comparison of social structures within cities of very different sizes

People make a city, making each city as unique as the combination of its inhabitants. However, some cities are similar and some cities are inimitable. We examine the social structure of 10 different cities using Twitter data. Each city is decomposed to its communities. We show that in many cases one city can be thought of as an amalgamation of communities from another city. For example, we find the social network of Manchester is very similar to the social network of a virtual city of the same size, where the virtual city is composed of communities from the Bristol network. However, we cannot create Bristol from Manchester since Bristol contains communities with a social structure that are not present in Manchester. Some cities, such as Leeds, are outliers. That is, Leeds contains a particularly wide range of communities, meaning we cannot build a similar city from communities outside of Leeds. Comparing communities from different cities, and building virtual cities that are comparable to real cities, is a novel approach to understand social networks. This has implications when using social media to inform or advise residents of a city.
Acamprosate Modulates Alcohol-Induced Oxidative Stress In Alcoholic Patients

Some authors have suggested possible loss of antioxidant levels in alcoholic subjects. Acamprosate may have 2+ modulator effect on antioxidant levels in the alcoholic subject due to its effects on Ca regulation. We inves- tigated effects of acamprosate on serum lipid peroxidation and antioxidant vitamin concentrations in alcoholic patients. Twelve male health control and twelve alcoholic patients were used in the study. After taken blood samples the patients received orally acamprosate for 3 weeks and blood samples were taken the patients again. Lipid peroxidation (LP) levels were higher in the alcohol group than in control although vitamin A, vitamin E and b-carotene values were lower in the alcohol group than in control. LP levels were decreased in treatment group compared with the alcohol group. Vitamin A and b-carotene in the treatment group were increased compared with the alcohol group. Serum vitamin C concentrations were not found to be statistically different in any of the groups. Oxidative stress has been proposed to explain the biological side effects of alcohol intake. Acamprosate modulated alcohol-induced oxidative stress and antioxidant vitamin levels in the alcoholic patients.
Public art in Taman Suropati as a medium in creating attractive and lively public space

The city authority increasingly has interested in culturalsustainability as an aspect of sustainable development and emphasize thedesign of public urban spaces that host cultural and social interactions. Inregard to create sustainability of public space, it is necessary to use bothphysical and aesthetic elements of the park and art in public realm can be apowerful tool to reach people and play an active role in forming andpresenting local identity of cities. In this paper, a research in TamanSuropati, Menteng, Jakarta, is conducted as a case study of how public artin the city park generates interaction between visitors. As a historicallandmark of the city, Taman Suropati has its own appeal to the people ofJakarta. The park has provided a good sample of how urban space isactivated through public art and community activities. By analyzing therelation between spatial elements and social activities in Taman Suropati, we can learn about the importance of public art to support communityinteraction and help to create an attractive and lively urban environment. Thus, this paper aims to investigate the role of public art as a tool forenhancing the quality of urban space and making creative, lively urbanopen spaces to promote a more sustainable urban living and maintain thepublic realm of cities as an interaction space.
