A Prediction Model for Recognition of Bad Credit Customers in Saman Bank Using Neural Networks

The aim of this paper is to present a model based on feed forward neural networks to recognize bad credit customers in Saman Bank. To find an appropriate structure for the proposed neural network model, three different strategies called quick, dynamic and multiple strategies are investigated. The registered data of credit customer in Saman Bank from 2000 to 2008 year is used. To prevent models from over fitting with training data specifications, according to cross validation, we divide existing data set into three subsets called training, testing, and validation set, respectively. To evaluate the proposed model, we compare the result of three different strategies in neural networks with each other and with some common prediction methods such as decision tree and logistic regression. The results revealed that the threelayer neural network based on the back propagation learning algorithm with quick strategy has higher accuracy.
Abnormal Compressor Noise Diagnosis Using Sound Quality Evaluation And Acoustic Array Method

A noise abnormal rotary compressor is analyzed with sound quality evaluation method. Sound power level (A), loudness, roughness and sharpness are calculated as objective evaluation parameters, and the results indicate that the abnormal compressor has a poor sound quality compared with a normal one. Acoustic array technique can identify target sound source of complicated shape accurately, and get rich sound field information compared to traditional near-field measurement with a sound level meter. In order to diagnose the abnormal noise, the compressor sound sources are identified and located in full frequency range through acoustic array method. As a result, the key frequencies are diagnosed and the corresponding sources are also located, which provide the effective evidence for the future improvement.
SQL Statement Logging for Making SQLite Truly Lite

The lightweight codebase of SQLite was helpful in making it become the de-facto standard database in most mobile devices, but, at the same time, forced it to take less-complicated transactional schemes, such as physical page logging, journaling, and force commit, which in turn cause excessive write amplification. Thus, the write IO cost in SQLite is not lightweight at all. In this paper, to make SQLite truly lite in terms of IO efficiency for the transactional support, we propose SQLite/SSL, a per-transaction SQL statement logging scheme: when a transaction commits, SQLite/SSL ensures its durability by storing only SQL statements of small size, thus writing less and performing faster at no compromise of transactional solidity. Our main contribution is to show that, based on the observation that mobile transactions tend to be short and exhibit strong update locality, logical logging can, though long discarded, become an elegant and perfect fit for SQLite-based mobile applications. Further, we leverage the WAL journal mode in vanilla SQLite as a transaction-consistent checkpoint mechanism which is indispensable in any logical logging scheme. In addition, we show for the first time that byte-addressable NVM (non-volatile memory) in host-side can realize the full potential of logical logging because it allows to store fine-grained logs quickly. We have prototyped SQLite/SSL by augmenting vanilla SQLite with a transaction-consistent checkpoint mechanism and a redo-only recovery logic, and have evaluated its performance using a set of synthetic and real workloads. When a real NVM board is used as its log device, SQLite/SSL can outperform vanilla SQLite's WAL mode by up to 300x and also outperform the state-of-the-arts SQLite/PPL scheme by several folds in terms of IO time.
Realtime Ray Tracing and its use for Interactive Global Illumination

Research on realtime ray tracing has recently made tremendous advances. Algorithmic improvements together with optimized software implementations already allow for interactive frame rates even on a single desktop PC. Furthermore, recent research has demonstrated several options for realizing realtime ray tracing on different hardware platforms, e.g. via streaming computation on modern graphics processors (GPUs) or via the use of dedicated ray tracing chips. Together, these developments indicate that realtime ray tracing might indeed become a reality and widely available in the near future. As most of todays global illumination algorithms heavily rely on ray tracing, this availability of fast ray tracing technology creates the potential to ﬁnally compute even global illumination – the physically correct simulation of light transport – at interactive rates. In this STAR, we will ﬁrst cover the different research activities for realizing realtime ray tracing on different hardware architectures – ranging from shared memory systems, over PC clusters, programmable GPUs, to custom ray tracing hardware. Based on this overview, we discuss some of the advanced issues, such as support for dynamic scenes and designs for a suitable ray tracing API. The third part of this STAR then builds on top of these techniques by presenting algorithms for interactive global illumination in complex and dynamic scenes that may contain large numbers of light sources. We believe that the improved quality and the increased realism that global illumination adds to interactive environments makes it a potential “killer application” for future 3D graphics.
Dynamics of the `field': multiple standpoints, narrative and shifting positionality in multisited research

The article contributes to the epistemological debates in feminism through the analysis of multisited research on jewellery production in India. The multisited research focuses on different localities — Noida Export Processing Zone (NEPZ), Delhi and villages of Medinipur having direct and indirect links to the global market. It analyses how the multiple sites structured by gender, class and age hierarchies reveal the multiple and fluid standpoints of different actors. The multiple standpoints of different actors feed into discursive practices of a complete exclusion of women from the production process of handmade jewellery in NEPZ, their marginal presence in Delhi, and their invisibility despite preponderance in the villages of Medinipur. These narratives constitute the subjectivity of men as `breadwinners' and of women as `housewives'. However, some women contest the discourses around marginalization of their work and present points of break in the configuration of power, questioning their subject position as `housewives'. Weaving these complex webs of narratives, I am reflexive of my multiple positionality as Indian, non-Bengali, elite, woman and the fluidity of my position as an insider/outsider in the `field'.
SUPPLEMENTARY MATERIAL FOR "WEAK CONVERGENCE RATES OF POPULATION VERSUS SINGLE-CHAIN STOCHAS- TIC APPROXIMATION MCMC ALGORITHMS "

Proof. Let M = sup θ∈Θ max{{h(θ), |v(θ)|} and V ε = {θ : d(θ, L) ≤ ε}. Applying Taylor's expansion formula (Folland, 1990), we have v(θ t+1) = v(θ t) + γ n+1 v h (θ t+1) + R t+1 , t ≥ 0, which implies that t i=0 γ i+1 v h (θ i) = v(θ t+1) − v(θ 0) − t i=0 R i+1 ≥ −2M − t i=0 R i+1. Since t i=0 R i+1 converges (owing to Lemma A.2), t i=0 γ i+1 v h (θ i) also converges. Furthermore, v(θ t) = v(θ 0) + t−1 i=0 γ i+1 v h (θ i) + t−1 i=0 R i+1 , t ≥ 0, {v(θ t)} t≥0 also converges. On the other hand, conditions (A 1) and (A 2) imply lim t→∞ d(θ t , L) = 0. Otherwise, there exists ε > 0 and n 0 such that d(θ t , L) ≥
A Photometric Redshift Galaxy Catalog from the Red-Sequence Cluster Survey

The Red-Sequence Cluster Survey (RCS) provides a large and deep photometric catalog of galaxies in the z′ and Rc bands for 90 deg2 of sky, and supplemental V and B data have been obtained for 33.6 deg2. We compile a photometric redshift catalog from these four-band data by utilizing the empirical quadratic polynomial photometric redshift fitting technique in combination with CNOC2 and GOODS/HDF-N redshift data. The training set includes 4924 spectral redshifts. The resulting catalog contains more than one million galaxies with photometric redshifts <1.5 and Rc < 24, giving an rms scatter σ(Δz) < 0.06 within the redshift range 0.2 < z < 0.5 and σ(Δz) < 0.11 for galaxies at 0.0 < z < 1.5. We describe the empirical quadratic polynomial photometric redshift fitting technique that we use to determine the relation between redshift and photometry. A kd-tree algorithm is used to divide up our sample to improve the accuracy of our catalog. We also present a method for estimating the photometric redshift error for individual galaxies. We show that the redshift distribution of our sample is in excellent agreement with smaller and much deeper photometric and spectroscopic redshift surveys.
Oligomers of ERBB3 Have Two Distinct Interfaces That Differ in Their Sensitivity to Disruption by Heregulin*

ErbB receptors associate in a ligand-dependent or -independent manner, and overexpression of epidermal growth factor receptor (ErbB1) or ErbB2 results in ligand-independent activation. Ligand-independent activation is poorly understood, and dimerization alone is not sufficient for activation. ErbB receptors also form higher order oligomers, but the mechanism of oligomer formation and their contribution to signaling are not known. The kinase-deficient ErbB3 as well as its extracellular domains are particularly prone to ligand-independent oligomerization, and oligomers are destabilized by binding of the ligand heregulin. In contrast, ligand binding facilitates heterodimerization with ErbB2 and is expected to stabilize an extended conformation of the ErbB3 extracellular domain (ECD) in which the dimerization interface is exposed. In the absence of ligand, ErbB3 can adopt a closed conformation that is held together by an intramolecular tether. We used a constitutively extended form of the ErbB3-ECD to analyze the conformation of the ECD in oligomers and the mechanism of oligomer disruption by heregulin. The extended conformation of the ECD forms oligomers more readily, suggesting the crystallographically defined dimer interface is one of the interfaces involved in oligomerization. Heregulin destabilizes oligomeric complexes but not dimers, which are neither stabilized nor disrupted by ligand binding, indicating a distinct second interface in oligomers of ErbB3. Cross-linking and activation studies on membrane-embedded ErbB3/ErbB2 chimeras confirm this dual effect of heregulin. Most of the ErbB3-ECD on the cell surface is apparently kept in an open conformation through oligomerization, and the resulting oligomers adopt a conformation representing a state of reduced activity.
Mock games: a new genre of pervasive play

In this paper we identify and characterize, in theory and by design example, a new genre of pervasive play for tweens that lies on the border between play and game, called mock games. The objective is to design digital support for more or less structured playfulness among preteen children, primarily girls, in a way that emphasizes humor, friendly battle and identity construction. The method used is a combination of a review of a number of theories of games and play and a field study into the social reality of children's playful activities. Based on these two investigations we characterize mock games as a genre and show that it is not covered well by any one of the reviewed theories, taking into account both social and technical aspects. Then we present a design example of such a system, DARE! We conclude by discussing ethical issues and set goals for future research.
Conformational analysis of HAMLET, the folding variant of human α‐lactalbumin associated with apoptosis

A combination of hydrogen/deuterium (H/D) exchange and limited proteolysis experiments coupled to mass spectrometry analysis was used to depict the conformation in solution of HAMLET, the folding variant of human α‐lactalbumin, complexed to oleic acid, that induces apoptosis in tumor and immature cells. Although near‐ and far‐UV CD and fluorescence spectroscopy were not able to discriminate between HAMLET and apo‐α‐lactalbumin, H/D exchange experiments clearly showed that they correspond to two distinct conformational states, with HAMLET incorporating a greater number of deuterium atoms than the apo and holo forms. Complementary proteolysis experiments revealed that HAMLET and apo are both accessible to proteases in the β‐domain but showed substantial differences in accessibility to proteases at specific sites. The overall results indicated that the conformational changes associated with the release of Ca2+ are not sufficient to induce the HAMLET conformation. Metal depletion might represent the first event to produce a partial unfolding in the β‐domain of α‐lactalbumin, but some more unfolding is needed to generate the active conformation HAMLET, very likely allowing the protein to bind the C18:1 fatty acid moiety. On the basis of these data, a putative binding site of the oleic acid, which stabilizes the HAMLET conformation, is proposed.
Physiological Performance Determinants of a 22-km Handbiking Time Trial.

PURPOSE To investigate physiological performance determinants of the partial laps and an overall 22-km handbiking (HB) time trial in athletes with high paraplegia. METHODS Seven male HB athletes with spinal cord injury (lesion levels thoracic 2-8) performed a laboratory maximal incremental test under cardiorespiratory-mechanical monitoring including respiratory-exchange ratio (RER), oxygen uptake (VO2), and mechanical power output (PO). Individual first and second ventilatory thresholds (VO 2VT1 and VO 2VT2), VO 2peak, and PO peak were posteriorly identified. Athletes also performed a simulated HB time trial along a 4-lap bike circuit under cardiorespiratory measurement. Overall metabolic cost (C) and %VO 2peak (ratio of VO2 to VO 2peak) were calculated from race data. Race performance was defined as mean race velocity (v). RESULTS athletes completed the 22-km HB time trial in 45 ± 6 min, at 29.9 ± 3.6 km/h, with %VO 2peak = 0.86 ± 0.10 and RER = 1.07 ± 0.17. VO 2peak (r = .89, P = .01), POpeak (r = .85, P = .02), VO 2VT1 (r = .96, P = .001), VO 2VT2 (r = .92, P = .003), and C (2nd lap, r = .78; 3rd lap, r = .80; and 4th lap, r = .80) were significantly (P < .05) positively correlated with race performance. Within-subjects correlation coefficient revealed a large and significant (r = .68, P < .001) relationship between %VO 2peak and v. CONCLUSIONS VO 2peak, PO peak, ventilatory thresholds, %VO 2peak, and C appeared to be important physiological performance determinants of HB time trial.
A spatial voting model where proportional rule leads to two-party equilibria

In this paper we show that in a simple spatial model where the government is chosen under strict proportional rule, if the outcome function is a linear combination of parties’ positions, with coefficient equal to their shares of votes, essentially only a two-party equilibrium exists. The two parties taking a positive number of votes are the two extremist ones. Applications of this result include an extension of the well-known Alesina and Rosenthal model of divided government as well as a modified version of Besley and Coate’s model of representative democracy.
Current Paranoid Thinking in Patients With Delusions: The Presence of Cognitive-Affective Biases

Background: There has been renewed interest in the influence of affect on psychosis. Psychological research on persecutory delusions ascribes a prominent role to cognitive processes related to negative affect: anxiety leads to the anticipation of threat within paranoia; depressive negative ideas about the self create a sense of vulnerability in which paranoid thoughts flourish; and self-consciousness enhances feelings of the self as a target. The objective of this study was to examine such affective processes in relation to state paranoia in patients with delusions. Methods: 130 patients with delusions in the context of a nonaffective psychosis diagnosis (predominately schizophrenia) were assessed for contemporaneous levels of persecutory ideation on 5 visual analog scales. Measures were taken of anxiety, depression, threat anticipation, interpretation of ambiguity, self-focus, and negative ideas about the self. Results: Of the patients, 85% report paranoid thinking at testing. Symptoms of anxiety and depression were highly prevalent. Current paranoid thinking was associated with anxiety, depression, greater anticipation of threat events, negative interpretations of ambiguous events, a self-focused cognitive style, and negative ideas about the self. Conclusions: The study provides a clear demonstration that a range of emotion-related cognitive biases, each of which could plausibly maintain delusions, are associated with current paranoid thinking in patients with psychosis. We identified biases both in the contents of cognition and in the processing of information. Links between affect and psychosis are central to the understanding of schizophrenia. We conclude that treatment of emotional dysfunction should lead to reductions in current psychotic experiences.
"What Do Boot Camps Really Achieve?": A Means-End Analysis of the Limited Service Volunteers Programme

This article identifies participants’ perceptions of the outcomes from Limited Service Volunteers at Burnham Military Camp, a programme that provides motivational intervention for the unemployed. Means-end theory has been used to examine the relationships between the activities (the “means”) and the resulting values (the “ends”). This article describes the most important outcomes, as perceived by participants during the Limited Service Volunteers programme. Means-end interviews were conducted with 85 participants of the October 2006 intake. Analysis of the data is represented in ladder maps, illustrating the links between individual activities and the associated outcomes. Demographic variables of age, gender and ethnicity highlight the variances of outcomes between these subgroups. A second set of means-end interviews was conducted with 28 participants by phone six months after the course, highlighting the outcomes that had a lasting impression on the participants. The results demonstrate the positive and lasting outcomes of the Limited Service Volunteers programme, and thus can be used to show the effects and enhance the design and delivery of the programme.
Left ventricular mass by echocardiographic measures in children and adolescents

Abstract Background Recent evidence in adults suggests that left ventricular mass measured as left ventricular mass/height1.7 predicts cardiovascular morbidity and mortality better than the two widely used indices, left ventricular mass/body surface area and left ventricular mass/height2.7. Standards of left ventricular mass/height1.7 have not been reported in children, for whom, owing to lack of significant cardiovascular morbidity and mortality, body mass index has traditionally been used as a potential cardiovascular risk factor. Methods In this retrospective study, 692 clinically normal children aged 1 day to 18 years underwent detailed echocardiographic assessment to assess whether any of the left ventricular mass indices – left ventricular mass/height1.7, left ventricular mass/body surface area, and left ventricular mass/height2.7 – are associated with obesity as measured by body mass index. Correlations, t-tests, and linear regressions were used for statistical testing. Results Left ventricular mass/height1.7 was better correlated (R2 = 0.36) with body mass index than left ventricular mass/body surface area (R2 = 0.179) and left ventricular mass/height2.7 (R2 = 0.006), although all three dependent variables show a significant correlation (p < 0.035). In addition, a higher percentage of obese patients were noted to have elevated left ventricular mass as measured by left ventricular mass/height1.7 than by the other two methods. Conclusions Left ventricular mass/height1.7 is a reliable indicator of obesity-associated left ventricular hypertrophy. Left ventricular mass/height1.7 can be used conveniently during transitions from youth to adults for long-term follow-up. These findings support the importance of including left ventricular mass/height1.7 in future studies of cardiovascular risks and preventive strategies in children and adolescents.
Recent developments in gastric endoscopic submucosal dissection: Towards the era of endoscopic resection of layers deeper than the submucosa

With technical advances in endoscopic submucosal dissection (ESD), several variations of endoscopic procedure derived from ESD and fusion procedures of endoscopy and laparoscopy for upper gastrointestinal submucosal tumor and cancer have recently been developed. The former includes endoscopic muscularis dissection (EMD), submucosal endoscopic tumor resection (SET), endoscopic submucosal tunnel dissection (ESTD) and endoscopic full‐thickness resection (EFTR), and the latter includes laparoscopic and endoscopic cooperative surgery (LECS), laparoscopy‐assisted endoscopic full‐thickness resection (LAEFR), and laparoscopic lymphadenectomy without gastrectomy following ESD. In the present article, recent developments in gastric ESD and advanced procedures derived from ESD are discussed.
A new treatment regimen with permethrin in scabies.

BACKGROUND Topical permethrin, applied once daily, is considered as the most effective treatment in scabies. METHODS Eighty-nine adult immunocompetent patients with scabies were treated with 5% permethrin cream: 42 patients were treated with a single application/day (group 1); 47 patients were treated with one application/day for two consecutive days (group 2). Clinical diagnosis of scabies was confirmed by microscopical examinations. The cream was stored in refrigerator and applied cold on the entire skin surface. The cream was left on the skin for 24 hours. No other topical or systemic drugs were allowed, except for a cleanser with chlorhexidine. The treatment was repeated in all patients 7-10 days later. The follow-up was 2 months after the end of the treatment. RESULTS Twenty-one patients (61.8%) in the group 1 and 34 patients (87.2%) in the group 2 were considered recovered both clinically and microscopically. Three patients (7.1%) in the group 1 and 4 patients (10.2%) in the group 2 developed a mild irritant contact dermatitis. During follow-up, three patients (7.1%) in the group 1 and two patients (4.2%) in the group 2 developed a recurrence or a re-infestation. CONCLUSIONS Five per cent permethrin, when applied as cold cream, on the entire skin surface, once daily for two consecutive days, is more effective than the single application in adult immunocompetent patients with scabies.
Development of a ZVT-PWM Buck Cascaded Buck–Boost PFC Converter of 2 kW With the Widest Range of Input Voltage

This paper describes the development of a new buck cascaded buck–boost power factor correction (PFC) converter of 2 kW with a soft-switching technique. For its wide range of input voltage, it operates in both buck and boost modes. The parameters are properly selected to endure voltage and current stress in all operating ranges. In addition, the electromagnetic interference (EMI) filter is used to reduce the EMI noise and guarantee continuous input current in buck operation. Moreover, the zero-voltage-transient pulse-width-modulation (ZVT-PWM) method is applied to improve the overall efficiency of the converter. The performance of the proposed PFC converter with the widest range of input voltage is evaluated by the hardware experimental test including harmonics analysis based on the International Electrotechnical Commission standard in all operating ranges. Also, the variations of power factor are theoretically analyzed in both buck and boost modes to determine the widest input range of the proposed PFC converter of 2 kW with an EMI filter. These are strongly required to commercialize it in practice. Finally, the efficiency of proposed PFC converter is compared with that of a conventional buck cascaded buck–boost PFC converter under various conditions.
