Comparative Analysis of Feature Selection Method to Predict Customer Loyalty

The growth of Fast Moving Consumer Goods (FMCG) industry is still showing double-digit and Indonesia becomes a potential market for the products FMCG, so that the competition between companies will be intense. The company have to attempted to survive, one of the way is to maintain customer loyalty. Data mining techniques can be used to predict customer loyalty. In data mining pra-processing, feature selection is one of the important thing to reduces the number of features, removes irrelevant, redundant, or data noise, and brings the immediate effects for applications: speeding up a data mining algorithm, improving mining performance such as the accuracy of the prediction and the comprehensive result. This paper aims to identify the relevant factors that affect the performance of the classification of customer loyalty with several feature selection method and to compare the classification performance in customers loyalty prediction of FMCG products. Data was obtained from the results of fast moving consumer goods customers questionnaires towards several brands of instant noodles in Lampung that was ranked TOP Brand Award Phase 1 2016, using nonprobability sampling method and convenience sampling technique. The result in this paper, chi square feature selection methods with threshold > 0.01 showed the best results, it is indicated by the highest accuracy of random forest classification algorithm, that is 83.2% for thirteenth features
Charge-insensitive qubit design derived from the Cooper pair box

Short dephasing times pose one of the main challenges in realizing a quantum computer. Different approaches have been devised to cure this problem for superconducting qubits, a prime example being the operation of such devices at optimal working points, so-called 'sweet spots. ' This latter approach led to significant improvement of T{sub 2} times in Cooper pair box qubits [D. Vion et al., Science 296, 886 (2002)]. Here, we introduce a new type of superconducting qubit called the 'transmon'. Unlike the charge qubit, the transmon is designed to operate in a regime of significantly increased ratio of Josephson energy and charging energy E{sub J}/E{sub C}. The transmon benefits from the fact that its charge dispersion decreases exponentially with E{sub J}/E{sub C}, while its loss in anharmonicity is described by a weak power law. As a result, we predict a drastic reduction in sensitivity to charge noise relative to the Cooper pair box and an increase in the qubit-photon coupling, while maintaining sufficient anharmonicity for selective qubit control. Our detailed analysis of the full system shows that this gain is not compromised by increased noise in other known channels.

Mitochondrial Dysfunction as a Mechanism for Pioglitazone-Induced Injury toward HepG2 Cell Line

Background: Thiazolidinediones (TZDs) are widely used for treatment of type II diabetes mellitus in humans. The first drug of this class, troglitazone, was withdrawn from the market due to a high incidence of hepatotoxicity. Several cases of liver injury induced by other TZDs such as pioglitazone is also reported. The mechanism of cellular injury induced by pioglitazone is not recognized precisely so far. Mitochondria is a postulated target for TZDs to induce injury. Methods: This investigation was designed to evaluate the cytotoxic effects of pioglitazone in cultured HepG2 cells. Cell death, glutathione level, occurrence of lipid peroxidation, and finally cellular adenosine triphosphate (ATP) content, as an index of mitochondrial functionality, were monitored in HepG2 cells after pioglitazone administration. Results: It was found that pioglitazone was toxic towards HepG2 cells concentration dependently and 1 mM of pioglitazone reduced cellular viability to less than 60% in 48 hours of incubation. Pioglitazone administration reduced ATP content of the cells, but did not induce oxidative stress in this cell line, as no lipid peroxidation and/or decrease in cellular glutathione were detected. Administration of ATP suppliers dihydroxyacetone (5 and 10 mM) and glyceraldehyde (1 and 5 mM), inhibited drop in cellular ATP induced by pioglitazone and prevented drug-induced cell death. Conclusion: These results suggest that pioglitazone affect cellular mitochondria and might cause cytotoxicity by prevention of ATP production.
MM-Wave Metamaterial Adjustable Antenna on Magnetically Biased Ferritic Substrate

The paper presents a mm-wave metamaterial coplanar waveguide (CPW) zeroth-order resonating (ZOR) antenna on magnetically biased ferrite substrate. The measurements demonstrate tuning of the resonant frequency and steering of the radiation characteristic depending on the strength of biasing magnetic field. The resonant frequency shifts about 1.1 GHz for magnetic biasing field strength variation between 0 T and 0.265 T. The return loss is reduced as result of elimination of ferrite low field loss. The radiation characteristic in transversal plane steers between approximately −15° and
Job demands–resources model in the context of recovery: Testing recovery experiences as mediators

The aim of the present study was to extend the original Job Demands–Resources (JD-R) model by taking into account recovery as an important mediation mechanism between work characteristics and well-being/ill-health. Specifically, we examined whether recovery experiences—strategies promoting recovery—might have a mediating role in the JD-R model among 527 employees from a variety of different jobs. The results showed that psychological detachment fully mediated the effects of job demands on fatigue at work and mastery partially mediated the effects of job resources on work engagement. Altogether, the results suggest that recovery merits consideration as a mediating mechanism in the JD-R model.
Push and bite: trade-offs between burrowing and biting in a burrowing skink (Acontias percivali)

Trade-offs are thought to be important in constraining evolutionary divergence, as they may limit phenotypic diversification. Limbless animals that burrow head-first have been suggested to be evolutionarily constrained in the development of a large head size and sexual head shape dimorphism because of potential trade-offs associated with burrowing. Here we use an acontiine skink (Acontias percivali) to test for the existence of trade-offs between traits thought to be important in burrowing (speed and force). As head size dimorphism has been shown to be limited in acontiine lizards, thus suggesting constraints on head size and shape, we additionally explore the potential for trade-offs between burrowing and biting. Our data show that A. percivali uses a burrowing style different from those previously described for caecilians and amphisbaenians, which relies on the use of extensive lateral and dorsoventral head movements. Our data also show that animals use their entire bodies to generate force, as peak force was determined by total length only. Additionally, both bite force and the time needed to burrow into the substrate were principally determined by relative head width, suggesting a trade-off between biting and burrow speed. Performance data were indeed suggestive of a correlation between bite force and the time needed to burrow, but additional data are needed to confirm this pattern. In summary, our data suggests that trade-offs may exist, and may have been of crucial importance in shaping the evolution of head shape in A. percivali, and burrowing lizards more generally. © 2010 The Linnean Society of London, Biological Journal of the Linnean Society, 2011, 102, 91‐99.
Effects of sodium chloride and sodium gluconate concentration on hydration behavior and water transport in the red-spotted toad, Bufo punctatus

Effects of Sodium Chloride and Sodium Gluconate Concentration on Hydration Behavior and Water Transport in the Red spotted Toad, Bufo punctatus by Polly Ann Sullivan Dr. Karin Hoff and Dr. Stan Hillyard, Examination Committee Co-chairs Professors of Biology University of Nevada, Las Vegas Toads hydrate from standing water or moist substrates by osmotic absorbtion across the ventral skin. On land toads adopt a distictive posture called the water absorption response (WR) to maximize contact with the substrate and facilitate water absorption. Experiments using hydration behavior on moist substrates and rehdration rate in standing water or salt solutions in dehydrated Red-spotted toads (fiufo punctatus) were used to demonstrate that: 1) toads can distinguish among NaCl concentrations, 2) NaCl facilitates water uptake across the skin, and 3) transport of the chloride anion facilitates sodium uptake and affects sodium detection by the toad. The results of these studies also strongly suggest that general osmotic mechanisms as well as epithelial sodium channels function in chemosensation across the amphibian skin and that the ventral skin and the feet may have different roles in chemosensation.

Cuticular lipids as semiochemicals in paper wasps and other social insects

Strong evidence indicates that in Polistes wasps, as in other social insects, epicuticular lipids are involved in several aspects of recognition, such as nest-, nestmate- and fertility recognition. This evidence is based both on the study of differences in composition between groups of conspecific individuals (members of different colonies; age groups; dominants and subordinates; fertile and infertile individuals), and on bioassays. The first part of this review considers the general characteristics of Polistes epicuticular hydrocarbons and summarises what is currently known about the non-hydrocarbon cuticular lipids. The second part concerns the most relevant contributions of the work on Polistes towards an understanding of the role of epicuticular hydrocarbons as semiochemicals in social insects. Four aspects, highlighted in 1993 by Howard, as future directions for the study of epicuticular hydrocarbons will be considered: (i) the need for a complete determination of epicuticular hydrocarbon structures (in particular chirality); (ii) the role of individual hydrocarbons as semiochemicals, or of classes of hydrocarbons in the epicuticular mixtures; (iii) the intraspecific variability in epicuticular lipid composition; and, (iv) current knowledge about cuticular hydrocarbon perception by insects.
ELECTROMAGNETIC SCATTERING BY A DIMENSIONAL INHOMOGENEITY DUE TO AN OSCILLATING MAGNETIC DIPOLE

A numerical method of computing the electromagnetic response of two-dimensional earth models to an oscillating magnetic dipole is presented, The general ized electromagnetic variational integral is reduced to a sum of two-dimensional variational integrals by Fourier transformation, Discretization of each two-dimensional integral is carried out in terms of the secondary electric fields using the finite element method, Following the variational principle, each harmonic integral is reduced to a set of simultaneous equations. From each set of electric field solutions obtained by solving the simultaneous equations, the secondary magnetic fields are computed numerically. After inversely Fourier transforming the secondary electric and magnetic fields, the total fields are finally obtained by adding the analytically calculated primary fields, In order to formulate the source vector associated with each set of simultaneous equations, both the secondary electric fields along the external boundary and the primary electric fields at every node must be
Exposure to elevated pCO2 does not exacerbate reproductive suppression of Aurelia aurita jellyfish polyps in low oxygen environments

Eutrophication-induced hypoxia is one of the primary anthropogenic threats to coastal ecosystems. Under hypoxic conditions, a deficit of O2 and a surplus of CO2 will concurrently decrease pH, yet studies of hypoxia have seldom considered the potential interactions with elevated pCO2 (reduced pH). Previous studies on gelatinous organisms concluded that they are fairly robust to low oxygen and reduced pH conditions individually, yet the combination of stressors has only been examined for ephyrae. The goals of this study were to determine the individual and interactive effects of hypoxia and elevated pCO2 on the asexual reproduction and aerobic respiration rates of polyps of the scyphozoan Aurelia aurita during a manipulative experiment that ran for 36 d. pCO2 and pO2 were varied on a diel basis to closely mimic the diel conditions observed in the field. Exposure to low dissolved oxygen (DO) reduced asexual budding of polyps by ~50% relative to control conditions. Under hypoxic conditions, rates of respiration were elevated during an initial acclimation period (until Day 8), but respiration rates did not differ between DO levels under prolonged exposure. There was no significant effect of increased pCO2 on either asexual reproduction or aerobic respiration, suggesting that elevated pCO2 (reduced pH) did not exacerbate the negative reproductive effects of hypoxia on A. aurita polyps.
ffects of Lateral Trunk Support on Scoliotic Spinal lignment in Persons With Spinal Cord Injury : A adiographic Study

Objective: To develop a radiographic method for measuring he spinal alignment of a person in a seated position and with hich to investigate the effects of lateral trunk supports (LTS) n special seating on the frontal and sagittal spinal alignment in ersons with spinal cord injury (SCI). Design: Before-after trial. Setting: University-based research laboratory. Participants: Ten men and 7 women who had SCI with coliosis (age, 35.4 9.4y; injury level, C5-T11) voluntarily articipated. Intervention: An adjustable seating system with LTS. Main Outcome Measures: Radiographs of the spine in the nteroposterior (AP) and lateral directions were taken while itting on an adjustable seating system without and with LTS. he Cobb angles and scoliotic indices based on the AP radioraphic images and the angles of the thoracic and lumbar spine ased on lateral were calculated. The relative change in angle RCA) with LTS in terms of the percentage reduction of the obb angles was also obtained. Results: The Cobb angles and scoliotic indices while sitting ith LTS were significantly smaller than those without, the ean difference of Cobb angles standard error (SE) being . 12° 1.64° (P .001) and those for the scoliotic indices being 09 . 04 (P .027). The mean RCA SE was 6.16% 4.23%. The RCA correlated weakly with the original obb angles (r .347, P .172). The LTS caused a signifiant reduction in the lumbar angles (P .001), but no signifiant effects on the thoracic angles were found. Conclusions: The radiographic findings demonstrate imroved scoliotic spinal alignment in the frontal plane and educed lumbar angles in the sagittal plane in persons with SCI hen seated in a special seat and using LTS.
The strain-rate sensitivity of high-strength high-toughness steels.

The present study examines the strain-rate sensitivity of four high strength, high-toughness alloys at strain rates ranging from 0.0002 s-1 to 200 s-1: Aermet 100, a modified 4340, modified HP9-4-20, and a recently developed Eglin AFB steel alloy, ES-1c. A refined dynamic servohydraulic method was used to perform tensile tests over this entire range. Each of these alloys exhibit only modest strain-rate sensitivity. Specifically, the strain-rate sensitivity exponent m, is found to be in the range of 0.004-0.007 depending on the alloy. This corresponds to a {approx}10% increase in the yield strength over the 7-orders of magnitude change in strain-rate. Interestingly, while three of the alloys showed a concominant {approx}3-10% drop in their ductility with increasing strain-rate, the ES1-c alloy actually exhibited a 25% increase in ductility with increasing strain-rate. Fractography suggests the possibility that at higher strain-rates ES-1c evolves towards a more ductile dimple fracture mode associated with microvoid coalescence.
The SEMA referential framework : Avoiding ambiguities between security and safety

This document is a preprint version of the article published by Elsevier in Int. Journal of Critical Infrastructure Protection, Volume 3, Issue 2, 2010. The meaning of the terms “security” and “safety” varies considerably from one context to another, leading to potential ambiguities. These ambiguities are very problematic in the critical infrastructure protection domain, which involves multiple actors and engineering disciplines. Avoiding misunderstandings caused by the ambiguities during the early stages of system design and risk assessment can save time and resources; it also helps ensure a more consistent and complete risk coverage. Based on a review of the existing definitions of security and safety, this paper identifies the main distinctions between the two notions. It proposes a referential framework called SEMA, which makes the latent differences underlying the use of the terms security and safety explicit. Three sectors are examined as use cases: the power grid, nuclear power generation, and telecommunications and data networks. Mapping the different sector definitions of security and safety in the SEMA framework makes their respective meanings explicit and reveals inconsistencies and overlaps.
Flexural strength and ductility of reinforced normal- and high-strength concrete beams

A number of singly reinforced concrete beams made of normal- and high-strength concretes were tested under monotonically increasing loads to study their flexural behaviour and to compare the flexural ductility of normal- and high-strength concrete beams. The flexural strength results verified that British Standard BS 8110, after modification as per the recommendation of The Concrete Society Technical Report 49, is reasonably accurate for application to high-strength concrete beams. On the other hand, the flexural ductility results revealed that the major structural parameters determining the ductility of singly reinforced beams are: (1) for given materials, the tension steel ratio; and (2) in more general cases, the tension steel to balanced steel ratio and the concrete grade. Based on the available test results, a simple formula for predicting the ductility of normal- and high-strength concrete beams is developed. Lastly, in order to avoid brittle failure, it is proposed to set a maximum limit to the ten.
Socioeconomic Differences and Family Clustering of Infant and Child Mortality: A Multilevel Analysis of Rural Southern Sweden, 1766-1895

This paper focuses on how differences by socio-economic status, sex, and family unit in infant and child mortality developed during the first stage of the demographic transition. It uses multilevel Cox regression controlling for shared unobserved factors at the family level included to examine this issue. The problem of comparing the impact of unobserved factors at family level with the effects of observed factors is solved by employing a new method for converting the variation stemming from unobserved factors at family level into Median Hazard Ratios (MHR), directly comparable with relative risks. The data are for a rural area in Southern Sweden and comes from the Scanian Demographic Database. The principal findings are that while socioeconomic differences in child mortality widened and became much larger than sex differences by the end of the nineteenth century, differences between families belonging to the same socioeconomic group were even larger.

广西龙滩水库地壳 Q S 二维成像

本文收集了广西龙滩水库地震监测台网2006年9月至2016年12月精定位后的3 382次 M L ≥0地震的数字波形资料，采用二维衰减成像技术获得了龙滩水库库区的 Q S 二维分布图像。 结果显示：龙滩水库库区 Q S 的横向不均匀变化明显， Q S 低值区围绕着库区近似呈环形分布；在 Q S 低值分布区附近，大多为河流与断裂带的交汇处； Q S 低值分布主要对应于透水性较强的岩性地区。 以上现象表明 Q S 低值分布受水、断裂、岩性等3种因素的影响，由此初步推断库水可能沿着断裂上的岩石破碎带及节理、裂隙发育地区和具有较强透水性岩层区域向下渗透，使得岩石孔隙中充满流体，内摩擦增大，地震波剧烈衰减，从而使 Q S 值大幅下降。 结果还表明：大多数地震发生在 Q S 高、低值过渡区域，这种“软”、“硬”介质的交界处，容易积累应变能，孕育地震。 这是由于当 Q S 高、低值过渡区域受到水的加载作用及其对裂隙边界的润滑作用，发震断层的抗剪强度降低，使滑动容易产生，从而诱发地震。
Change detection in a dynamic stream of attributed networks

Abstract While anomaly detection in static networks has been extensively studied, only recently have researchers focused on dynamic networks. This trend is mainly due to the capacity of dynamic networks to represent complex physical, biological, cyber, and social systems. This article proposes a new methodology for modeling and monitoring dynamic attributed networks for quick detection of temporal changes in network structures. In this methodology, the generalized linear model (GLM) is used to model static attributed networks. This model is then combined with a state transition equation to capture the dynamic behavior of the system. Extended Kalman filter (EKF) is used as an online, recursive inference procedure to predict and update network parameters over time. In order to detect changes in the underlying mechanism of edge formation, prediction residuals are monitored through an exponentially weighted moving average (EWMA) control chart. The proposed modeling and monitoring procedure is examined through simulations for attributed binary and weighted networks. Email communication data from the Enron corporation is used as a case study to show how the method can be applied in real-world problems.
