CBR-Based Fuzzy Support Vector Machine for Financial Distress Prediction
Authors: Cao Yu , Chen Xiaohong 
Published: July 2013

Abstract
Financial distress prediction has attracted wide attention since the 1960s. With the development of quantitative methods and computing tools, the models of financial distress prediction are constantly innovated. Commonly used models in this area include multiple discriminant analysis (MDA), logit, decision trees (DT), neural networks (NN), support vector machine (SVM), and case-based reasoning (CBR), etc. Support vector machine (SVM), because of its excellent generalization ability, has been a hot subject nowadays. Especially, fuzzy SVM (FSVM) has achieved great development in recent years. As choosing an appropriate fuzzy membership is an important issue in FSVM, in this paper we propose a new fuzzy membership for FSVM combined with CBR. Generally, our basic idea is to detect the outliers by their k-nearest neighbors, all or the majority of which are enclosed with the other class, and then assign them a lower fuzzy membership by the output of CBR. By adopting the hold-out method 30 times to generate 30 hold-out data, the empirical experiment shows the feasibility and validity of the proposed CBR-based fuzzy SVM for Chinese listed companies' financial distress prediction.
Selection of Modified Lot Sensitive Sampling Inspection Plans for Isolated Lots With Small Acceptance Numbers

Published: July 2013

Abstract
A lot sensitive sampling plan is an inspection procedure that involves a single sample with a zero acceptance number, and it is useful in the areas of compliance and safety-related testing. It is regarded as a consumer-oriented plan and is applied for an individual isolated lot, giving protection in terms of the limiting quality level. A major disadvantage of the plan is that it creates the possibility of the rejection of good lots because of the severity of the acceptance criteria involved in the plan. In this paper, a modified lot sensitive procedure that uses the repetitive group sampling procedure with small acceptance numbers is proposed. It can be considered as an alternative to the lot sensitive single sampling plan. The selection of the plans providing protection to the producer and the consumer in terms of acceptable and limiting quality levels with associated risks is discussed through illustrations. Tables for determining the sample size and the points for the plot of the operating characteristic curves of the plans are constructed using ƒ-binomial approximation to a hypergeometric distribution.

Abstract
Our research was conducted at the Agricultural Experimental and Research Station (Deyrab), College of Food and Agricultural Sciences, King Saud University, Riyadh, Saudi Arabia in the 2011 and 2012 seasons. Twenty-one date palm females were selected, introduced into a randomized complete block design (RCBD), and subjected to three pruning treatments concerning the leaf/bunch ratio, whereas eight bunches were left on each experimental tree. The tested treatments, after two applications (after fruit harvesting and fruit setting), were: T1 = 8 leaves/bunch, first week in November, T2 = 10 leaves/bunch, first week in November, T3 = 12 leaves/bunch, first week in November, T4 = 8 leaves/bunch, first week in May, T5 = 10 leaves/bunch, first week in May, T6 = 12 leaves/bunch, first week in May, and T7 = control, without pruning. Control pruning treatment resulted in clear reduction in the yield/tree, whereas T5 (10 leaves/bunch, first week in May) gave the highest yield/tree. T5 led in most physical and chemical properties in both seasons. Fruits of T5 and T6 treatments revealed significant increments in fruit moisture percentage, as compared with the control. Generally, yield and fruit quality of Barhi date palm cultivar growing in Riyadh, Saudi Arabia, had improved leaf/bunch ratios and it was found that 10 leaves/bunch was sufficient to obtain a suitable yield of good quality fruits in the first week of May.

Vertically aligned carbon nanotube films are good thermal interface materials because of their high thermal conductance and mechanical compliance. In this study, the authors bond carbon nanotube films and metallized silicon chips together using thermocompression method in a magnetic field to decrease the thermal contact resistance between them. Nickel is considered as the deposition metal because of its strong cohesion and good affinity on the carbon nanotube surface and it is ferromagnetic in nature. Bonding is demonstrated in vacuum chamber under the influence of temperature (300°C) and pressure (180 KPa). The resistance of the carbon nanotube film is measured with a thermal transient tester that can provide the structure function of the sample, so that people can know detailed thermal resistance. In general, the thermal contact resistance of the sample enhanced with magnetic field that the author measured is 34·24 mm2K/W that is 10% lower than the sample without enhancement. This study reveals that magnetic field can enhance the bonding strength to decrease the thermal contact resistance.

Summary
Many completion engineers use laboratory sand-retention testing as a tool to select a screen for standalone sand-control applications, some focusing on prepack and others on slurry testing. Those who use slurry tests for screen selection typically do so on the basis of the conventional wisdom that slurry testing is more challenging; thus, it represents the worst-case scenario for sand production. Furthermore, the general belief in the industry has been that metal-mesh screens with a "pore structure" are better for sand retention compared with wire-wrap screens (WWSs) of slot geometry, although they are more prone to "plugging." These are just a few of the many myths that exist in screen selection for standalone screen (SAS) applications.
Recent papers on the modeling of sand retention by screens of various geometries, and supported by laboratory experiments, provided the tools for predicting sand production in both prepack and slurry conditions, as well as allowing for a systematic performance comparison of various screens by use of the entire particle-size distribution (PSD) of formation sands (Mondal et al. 2011 and 2012; Chanpura et al. 2012, 2013).
In this paper, we discuss and challenge many myths in the screen selection for SAS applications and substantiate our findings with modeling and experimental data. The conditions under which a slurry or a prepack test would be more conservative are identified, highlighting the mechanisms of sand retention (size exclusion or bridging dominated). We demonstrate that the current thinking that prepack tests are always more conservative from a sand-production standpoint is incorrect. We also show that the concept that metal-mesh screens are always superior for sand retention than WWSs is incorrect, highlighting the factors that affect sand production through various screens [e.g., open flow area (OFA), wire thickness, and fraction of bridging-sized particles in the formation sand]. Finally, a methodology for screen selection in SAS applications is proposed.

ABSTRACTAegilops tauschii Coss., the D‐genome progenitor of hexaploid wheat (Triticum aestivum L.), is an important source of useful genes for wheat improvement. We characterized a germplasm collection of 118 Ae. tauschii accessions for response to stripe rust, a devastating disease caused by the fungus Puccinia striiformis f. sp. tritici (Pst). We evaluated tillering stage and adult‐plant resistance to stripe rust using prevalent Pst races from the United States and China. Resistant accessions predominated in Ae. tauschii subsp. strangulata and Ae. tauschii subsp. tauschii from the Caspian Sea region. We further analyzed the inheritance of stripe rust resistance by inoculating F2 plants of 60 crosses with a mixture of Chinese Pst races. Crosses between resistant and susceptible lines indicated both dominant and recessive inheritance. Tests of allelism among 14 highly resistant accessions indicated the common presence of YrAS2388, previously mapped on chromosome arm 4DS, in all accessions. In conclusion, the study presented valuable data on stripe rust resistance in Ae. tauschii, which assist with informed introgression of the D‐genome trait for stripe rust resistance in common wheat.

ABSTRACTTraffic simulators are often utilized when researching turfgrass wear tolerance and recovery. However, the availability of a durable traffic simulator capable of producing dynamic force is limited. Therefore, the objectives of this research were to: (i) evaluate a novel traffic simulator with improved durability and capable of producing dynamic force and (ii) evaluate the biophysical effects of the traffic simulator on a native soil turfgrass system. The Baldree traffic simulator is a modified Ryan GA 30 (Jacobsen, A Textron Company, Charlotte, NC) riding aerification unit, equipped with fabricated, spring loaded steel plate feet studded with screw in cleats. The effects of this unit on a ‘Tifway’ bermudagrass [Cynodon dactylon (L.) Pers. × C. transvaalensis Burtt‐Davy] system established on a Tifton loamy sand (fine‐loamy, kaolinitic, thermic Plinthic Kandiudults) were evaluated at the Coastal Plains Experiment Station, Tifton, GA. Factors included location (1 and 2) and traffic rate (0, 12, and 24 passes applied over a 6 wk period). Field data included soil bulk density, turf density, and percent green turf cover. An in‐ground force plate at the McPhail Equine Performance Center, East Lansing, MI was used to quantify vertical and net shear ground reaction force produced by the Baldree traffic simulator when operated in the forward and backward direction. The Baldree traffic simulator produced more cleat marks per pass than the Brinkman and Cady traffic simulators. At the low traffic rate the Baldree traffic simulator increased soil bulk density, while turf density and percent green turf cover decreased; therefore, the tool can be used to simulate heavy traffic conditions with a minimum number of passes.
Putrescine Mediates Aluminum Tolerance in Red Kidney Bean by Modulating Aluminum‐Induced Oxidative Stress
Authors: Wang Huahua , Liang Weihong , Huang Junjun 
Published: July 2013

ABSTRACTPolyamines are important molecules modulating numerous environment stresses in plants. In the present study, the role of putrescine (Put) in the Al tolerance of red kidney bean (Phaseolus vulgaris) was investigated. In roots of red kidney bean, Al stress led to a marked increase of both free Put content and Put‐biosynthetic enzymes activities, and arginine decarboxylase pathway played a predominant role in Al‐induced increase in Put accumulation. Treatment of seedlings with Put reduced Al‐induced lipid peroxidation and reactive oxygen species (ROS) generation, thus alleviating Al‐induced inhibition of root elongation and Al accumulation in root apices. On the other hand, treatment with Put biosynthesis inhibitors reduced Al‐induced Put accumulation and enhanced Al toxicity of red kidney bean. Furthermore, Put treatment inhibited Al‐induced NADPH oxidase activity in roots, while Put biosynthesis inhibitors enhanced NADPH oxidase activity under Al stress. In addition, application of NADPH oxidase inhibitor reduced Al‐induced ROS generation, suggesting that ROS generation under Al stress is mediated, at least in part, by NADPH oxidase. Taken together, these results indicate that Put plays an important role in Al tolerance of red kidney bean by inhibiting NADPH oxidase activity, thus reducing Al‐induced oxidative stress.
Social Change and Increasing of Bipolar Disorders: An Evolutionary Model
Authors: Carta Mauro Giovanni 
Published: July 2013

Introduction:
The objective of this paper is to see if behaviours defined as pathological and maladjusted in certain contexts may produce adaptive effects in other contexts, especially if they occur in attenuated form. Interactions between environment and behaviour are studied from an evolutionary standpoint in an attempt to understand how new attitudes emerge in an evolving context.

Methodology:
Narrative review. Following an historical examination of how the description of depression in Western society has changed, we examine a series of studies performed in areas where great changes have taken place as well as research on emigration from Sardinia in the 1960s and 70s and immigration to Sardinia in the 1990s.

Results and conclusions:
If we postulate that mood disorders are on the increase and that the epidemic began in the 17th century with the "English malady", we must suppose that at least the "light" forms have an adaptive advantage, otherwise the expansion of the disorder would have been self-limiting. "Compulsive hyper-responsabilization”, as well as explorative behaviours, may represent a base for adaptation in certain conditions of social change. The social emphasis in individualism and responsibility may have changed not only the frequency, but also the phenomenology of mood disorders particularly the increases in bipolar disorders. From the sociobiological standpoint the conditions that may favour "subthreshold" bipolar or depressive features are to be considered in relation to the contextual role of gender and the different risks of the two disorders in males and females.
On Information Systems Complexity and Vulnerability
Authors: Cong Yu , Romero Jorge 
Published: July 2013

ABSTRACT
This study examines the relationship between information systems complexity and information systems vulnerability from the perspective of the enhanced internal controls after Sarbanes-Oxley. It is conjectured that the increased statutory and regulatory requirements on more stringent internal controls increase information systems complexity and, therefore, increase information systems vulnerability. This study hypothesizes that the increased information systems complexity also increases information systems vulnerability even though the overall internal control is improved. The results of the empirical tests support the hypotheses.
Three-dimensional evaluation of upper airway following rapid maxillary expansion: A CBCT study
Authors: El Hakan , Palomo Juan Martin 
Published: July 2013

ABSTRACT

Objectives:
To evaluate, by using cone beam computed tomography, the skeletal, dental, oropharyngeal (OP) airway volume, and nasal passage (NP) volume changes that occur after rapid maxillary expansion (RME).

Materials and Methods:
Two groups were selected, each with 35 patients (15 males, 20 females), an RME group (mean age, 14.02 ± 1.46 years) and a control group (mean age, 14.10 ± 1.44 years). The RME group consisted of patients with maxillary constriction who were treated with Hyrax palatal expanders, and the control group comprised age- and sex-matched patients who underwent comprehensive orthodontic treatment without the use of a rapid maxillary expander.

Results:
All of the transverse skeletal (medial orbital width, lateral nasal width, maxillary width, and mandibular width) and interdental (intermolar, interpremolar, and intercanine) parameters were significantly enlarged in the RME group. A statistically significant increase in airway variables was seen in both groups between pretreatment (T0) and final records (T1). The mean increase of NP airway volume for the RME group (1719.9 ± 1510.7 mm3) was twofold compared with the control group (813.6 ± 1006.7 mm3), and no intergroup significant difference was found for the OP volume.

Conclusions:
Rapid maxillary expansion creates a significant increase in nasal passage airway volume but no significant change in the oropharyngeal airway volume.

Published: July 2013

OBJECTIVE
Plasma copeptin, a surrogate for vasopressin, was associated with albuminuria in population-based studies. These associations are consistent with the effect of vasopressin on albuminuria observed in humans and rodents. The objective of this study was to determine whether plasma copeptin is an independent marker of risk of renal events in people with type 2 diabetes and albuminuria.

RESEARCH DESIGN AND METHODS
We studied 3,101 participants of the DIABHYCAR trial (6-year follow-up) with type 2 diabetes and albuminuria. A renal event was defined as doubling of serum creatinine or development of end-stage renal disease.

RESULTS
During follow-up, 86 renal events occurred in 76 subjects (2.45%). Incidences by tertiles of baseline plasma copeptin were 1.06% (T1), 1.45% (T2), and 4.84% (T3). They were 2.43% (T1), 5.11% (T2), and 11.81% (T3) for the subset of subjects with macroalbuminuria at baseline (n = 729). Hazard ratio for plasma copeptin tertiles as a risk for renal events was 4.79 (95% CI, 2.48–9.24; P &lt; 0.0001; for T3 vs. T1). In a stepwise regression analysis, urinary albumin excretion and plasma copeptin remained positively associated and HDL cholesterol and estimated glomerular filtration rate were inversely associated with the incidence of renal events. These independent predictors explained ∼18% of the variance of the outcome. The yearly variations of estimated glomerular filtration rate by copeptin tertiles were −1.43 ± 0.51 (T1), −2.29 ± 0.49 (T2), and −3.52 ± 0.44 mL/min/1.73 m2 per year (T3) (P = 0.005) in subjects with macroalbuminuria.

CONCLUSIONS
Plasma copeptin may help to identify subjects with diabetic chronic kidney disease who are at high risk for renal function decline.
Microleakage of Nanofilled Resin-modified Glass-ionomer/Silorane- or Methacrylate-based Composite Sandwich Class II Restoration: Effect of Simultaneous Bonding
Authors: Shafiei F , Akbarian S 
Published: July 2013

SUMMARY

Objectives
Microleakage of composite restorations at the cervical margin placed apically to the cementoenamel junction (CEJ) is still a concern. This study evaluated the effect of simultaneous bonding application on cervical sealing of nano-ionomer/silorane- or methacrylate-based composite open sandwich Class II restorations in the modified technique compared with that of conventional bonding.

Methods and Materials
In 60 sound maxillary premolars, two standardized Class II cavities were prepared with cervical margins 1 mm below the CEJ. The teeth were randomly divided into six groups of 10 teeth each. In the first three groups (groups 1-3), Clearfil SE Bond and Clearfil APX (Kuraray) were used for restoration in the total bonding technique (group 1), conventional open sandwich technique associated with a nano-ionomer (Ketac N100, 3M ESPE) (group 2), and modified open sandwich technique with simultaneous bonding application for both nano-ionomer and composite (group 3). In the second three groups (groups 4-6), Silorane Adhesive and Filtek Silorane composite (3M ESPE) were used in the same manner as in the first three groups, respectively.

Results
The simultaneous bonding application in the modified sandwich restorations (with SE Bond or Silorane Adhesive) resulted in a significant reduction of the cervical microleakage compared with that of the conventional bonding (p&lt;0.05). However, microleakage of the modified technique was similar to that of the total bonding (with SE Bond or Silorane Adhesive) (p&gt;0.05), both showing good marginal seal.

Published: July 2013

Abstract
Objective—To determine the lowest ACTH dose that would induce a significant increase in serum cortisol concentration and identify the time to peak cortisol concentration in healthy neonatal foals.
Design—Prospective randomized crossover study.
Animals—11 healthy neonatal foals.
Procedures—Saline (0.9% NaCl) solution or 1 of 4 doses (0.02, 0.1, 0.25, and 0.5 μg/kg [0.009, 0.045, 0.114, and 0.227 μg/lb]) of cosyntropin (synthetic ACTH) was administered IV. Serum cortisol concentrations were measured before and 10, 20, 30, 60, 90, 120, 180, and 240 minutes after administration of cosyntropin or saline solution; CBCs were performed before and 30, 60, 120, and 240 minutes after administration.
Results—Serum cortisol concentration was significantly increased, compared with baseline, by 10 minutes after cosyntropin administration at doses of 0.1, 0.25, and 0.5 μg/kg. Serum cortisol concentration peaked 20 minutes after administration of cosyntropin at doses of 0.02, 0.1, and 0.25 μg/kg, with peak concentrations 1.7, 2.0, and 1.9 times the baseline concentration, respectively. Serum cortisol concentration peaked 30 minutes after cosyntropin administration at a dose of 0.5 μg/kg, with peak concentration 2.2 times the baseline concentration. No significant differences were detected among peak serum cortisol concentrations obtained with cosyntropin administration at doses of 0.25 and 0.5 μg/kg. Cosyntropin administration significantly affected the lymphocyte count and the neutrophil-to-lymphocyte ratio.
Conclusions and Clinical Relevance—Results suggested that in healthy neonatal foals, the lowest dose of cosyntropin to result in significant adrenal gland stimulation was 0.25 μg/kg, with peak cortisol concentration 20 minutes after cosyntropin administration.
Thin sequences in the corona of H ∞

AbstractIn this paper we consider several conditions for sequences of points in M(H ∞) and establish relations between them. We show that every interpolating sequence for QA of nontrivial points in the corona $$M(H^\infty )\backslash \mathbb{D}$$ of H ∞ is a thin sequence for H ∞, which satisfies an additional topological condition. The discrete sequences in the Shilov boundary of H ∞ necessarily satisfy the same condition.

AbstractThis paper deals with a rationality condition for groups. Let n be a fixed positive integer. Suppose every element g of the finite solvable group is conjugate to its nth power g n. Let p be a prime divisor of the order of the group. We conclude that the multiplicative order of n modulo p is small, or p is small.
