Influence Analysis and Prediction of ESDD and NSDD Based on Random Forests

Equivalent salt deposit density (ESDD) and non-soluble deposit density (NSDD) measurements are a basic requirement of power systems. In order to predict the site pollution severity (SPS) of insulators, a new method based on random forests (RFs) is proposed. Using mutual information (MI) theory and RFs, the weights of factors related to the SPS of insulators are analyzed. The samples of contaminated insulators are extracted from the transmission lines of high voltage alternating current (HVAC) and high voltage direct current transmission (HVDC). The regression models of RFs and support vector machines (SVM) are constructed and compared, which helps to support the lack of information in predicting NSDD in previous works. The results are as follows: according to the mean decrease accuracy (MDA), mean decrease Gini, (MDG), and MI, the types of the insulators (including surface area, surface orientation, and total length) as well as the hydrophobicity are the main factors affecting both ESDD and NSDD. Compared with NSDD, the electrical parameters have a significant effect on ESDD. For the influence factors of ESDD, the weights of the insulator type, hydrophobicity, and meteorological factors are 52.94%, 6.35%, and 21.88%, respectively. For the influence factors of NSDD, the weights of the insulator type, hydrophobicity, and meteorological factors are 55.37%, 11.04%, and 14.26%, respectively. The influence voltage level ( vl ), voltage type ( vt ), polarity/phases ( pp ) exerted on ESDD are 1.5 times, 3 times, and 4.5 times of NSDD, respectively. The influence that distance from the coastline ( d ), wind velocity ( wv ), and rainfall ( rf ) exert on NSDD are 1.5 times, 2 times, and 2.5 times that of ESDD, respectively. Compared with the natural contamination test and the SVM regression model, the RFs regression model can effectively predict the contamination degree of insulators, and the relative error of the predicted ESDD and NSDD is 8.31% and 9.62%, respectively.
Impacts of Studying in a Different Cultural Environment: Graduate International Students' Perceptions

Dr. John Fischer, Advisor Stories reveal that people raised in a particular culture have always journeyed to other cultures/places with the aim of trading, learning, teaching, or converting others. Even though, in the olden days, the ability to travel more than a few miles from an individual’s place of origin was not common and considered a special opportunity, over time, this has evolved (Bochner, 2006). Technological advancements, legal regulation changes, and rise in natural/ human-made disasters have contributed to the constant growth in the ability for individuals to migrate from their national/ethnic boundaries (Bochner, 2006) making cross-cultural contact a global experience. In this present society, individuals have experienced various levels of cultural impact by being temporary residents or members of a society that receives temporary residents. Although cross-cultural contact is dominant in the society, it does not make it easy to deal with (Sumer, 2009). In other words, coping and adjusting to new a new cultural learning environment is challenging for international students. The purpose of this research was to review, analyze and qualitatively investigate how graduate international students perceive the impacts of studying in a different cultural learning environment. The research question this study attempts to answer is how do graduate international students perceive studying in a different cultural environment impacts them? The participants in this study were graduate international students attending a Midwest American University. These students originated from different countries, cultures and backgrounds. The method of qualitative research that was utilized in this study is
Moving psychiatric patients from hospital to community: views of patients, providers, and families.

OBJECTIVE Differences in the perspectives of severely and persistently ill patients, their family members, and clinical care providers on key aspects of community-based care were examined to help inform community service planning and development. METHODS A sample of 183 patients being considered for relocation from psychiatric facilities in Alberta, Canada, to community-based care, were interviewed, as were their primary clinical care providers. Family members of 130 patients were also interviewed. RESULTS Among the 130 patient-family pairs, 41 percent disagreed about the desirability of relocation, with fewer patients favoring relocation than families. Forty-nine percent of the pairs disagreed about the desired proximity to the family of the relocated patient, with the patient desiring closer proximity than the family member in about half of these cases. Fifty-three percent of the pairs disagreed about the amount of financial and emotional support that the family would provide after relocation. In half of these cases, patients believed the family would provide a higher level of support than the family indicated it could. Among the patients, 49 percent preferred independent living, whereas only 10 percent of family members and 17 percent of clinical care providers preferred it. Fifty-five percent of patients expressed a clear desire to work, whereas care providers believed that only 12 percent of patients were employable. CONCLUSIONS Persistently mentally ill residents of psychiatric facilities express clear preferences about key aspects of community-based care when they are asked, and these preferences often reflect different views from those expressed by either family members or clinical care providers.
Impact of Temperature on the Resistive Switching Behavior of Embedded $\hbox{HfO}_{2}$-Based RRAM Devices

Back-end-of-line integrated 1 × μm2 TiN/HfO2/Ti/TiN MIM memory devices in a 0.25- μm complementary metal-oxide-semiconductor technology were built to investigate the conduction mechanism and the resistive switching behavior as a function of temperature. The temperature-dependent I- V characteristics in fresh devices are attributed to the Poole-Frenkel mechanism with an extracted trap energy level at φ ≈ 0.2 eV below the HfO2 conduction band. The trap level is associated with positively charged oxygen vacancies. The electroformed memory cells show a stable bipolar switching behavior in the temperature range from 213-413 K. The off -state current increases with temperature, whereas the on-state current can be described by a weak metallic behavior. Furthermore, the results suggest that the I-V cycling not only induces significant changes in the electrical properties of the MIM memory devices, i.e., the increase in the off-state current, but also stronger temperature dependence. The temperature effect on the on-state and off-state characteristics is modeled within the framework of the quantum point-contact model for dielectric breakdown using an effective temperature-dependent confinement potential.
The Belief in a Just World and Immanent Justice Reasoning in Adults

Deciding that negative experiences are punishment for prior misdeeds, even when plausible causal links are missing, is immanent justice (IJ) reasoning (Piaget, 1932/1965). Three studies examined a just world theory analysis of IJ reasoning in adults (Lerner, 1980). Studies 1 and 2 varied the valence of a target person's behavior prior to them experiencing an unrelated negative (car accident, Study 1) or positive (lottery win, Study 2) outcome. Participants viewed the outcomes as the result of prior behavior most when they fit deservingness expectations (good person won the lottery, bad person injured in automobile accident), suggesting that just world concerns influenced IJ reasoning. The lottery-winning finding (Study 2) also extends IJ reasoning to positive experiences. A third study found that a manipulation of just world threat in one context (prolonged or ended suffering of an HIV victim) influenced IJ responses in a subsequent unrelated context (automobile accident scenario).
The brain in time: insights from neuromagnetic recordings

The millisecond time resolution of magnetoencephalography (MEG) is instrumental for investigating the brain basis of sensory processing, motor planning, cognition, and social interaction. We review the basic principles, recent progress, and future potential of MEG in noninvasive tracking of human brain activity. Cortical activation sequences from tens to hundreds of milliseconds can be followed during, e.g., perception, motor action, imitation, and language processing by recording both spontaneous and evoked brain signals. Moreover, tagging of sensory input can be used to reveal neuronal mechanisms of binaural interaction and perception of ambiguous images. The results support the emerging ideas of multiple, hierarchically organized temporal scales in human brain function. Instrumentation and data analysis methods are rapidly progressing, enabling attempts to decode the four‐dimensional spatiotemporal signal patterns to reveal correlates of behavior and mental contents.
Gastric Emptying in Premature Newborns with Acute Respiratory Distress

Objectives: The authors hypothesized that acute respiratory distress (ARD) delays gastric emptying. The objective was to test this hypothesis by assessing gastric emptying on the second and seventh days of life in premature infants with ARD resulting from pulmonary disease. Methods: Thirty-nine newborns with ARD starting on the first day of life were selected and paired with 39 healthy control newborns matched by weight (within 250 g). Gestational age was ≤35 weeks and birth weight was ≤1750 g for all subjects. Gastric emptying was assessed at 48.0 ± 24.0 hours and at 168.0 ± 24.0 hours of life. A test meal consisting of 3 mL/kg of 5% glucose in water labeled with phenol red was administered by gastric tube over 1 minute and gastric retention was determined as percent test meal remaining in the stomach 30 minutes after administration. Results: Gastric retention at 30 minutes varied considerably in both groups and was significantly higher (P < 0.01) in newborns with ARD (61.4%) than controls (51.8%) at 48.0 ± 24.0 hours, decreasing significantly after partial or full remission of ARD at 168 ± 24 hours of life. Gastric retention was 60.2% in newborns with feeding intolerance and 36.8% in tolerant newborns (P < 0.001) at 168 hours. ARD and periventricular or intraventricular hemorrhage were predictors of gastric retention at 48 ± 24 hours of life, whereas feeding intolerance and gestational age were predictors of gastric retention at 168 ± 24 hours. Gastric retention was inversely correlated with gestational age. Conclusion: Gastric emptying is delayed in premature infants with ARD during the first 72 hours of life and may impair the initiation of enteral feeding.
The morphology of the apical foramen in posterior teeth in a North Indian population.

AIM To determine the position and shape of the apical foramina in posterior teeth derived from an Indian population. METHODOLOGY A total of 800 freshly extracted maxillary and mandibular premolar and molar teeth from a native Haryana population were collected. Apices of teeth were stained with methylene blue and then examined stereomicroscopically (40x). The following observations were made: number of apical foramina; size and shape of the minor apical foramen; accessory foramina frequency, and deviation of the minor apical foramina (frequency and distance) from the apex. RESULTS The mean maximum and minimum diameter of the minor apical foramina ranged from 0.158 to 0.323 mm. The most common minor apical foramen shape was oval (81%). Frequency of accessory foramina was between 2% and 41% for the various tooth types. The frequency of deviation of the minor apical foramina from the anatomic apex varied from 43% to 83% and the distance of deviation in all the teeth was between 0.052 and 2.921 mm. CONCLUSIONS The incidence of oval canals was higher in this Indian population compared to other populations. In 92% and 96% of teeth the difference between the maximum and the minimum diameter of all foramina was less than or equal to 0.20 and 0.25 mm, respectively. Therefore, four to five instrument sizes larger than the first binding file would have been necessary to shape the minor apical foramen of more than 95% of the teeth included in this study to make them round.
Burkitt's lymphoma in adults with and without human immunodeficiency virus infection

Burkitt's lymphoma (BL) accounts for 1‐2% of all cases of non‐Hodgkin's lymphoma (NHL) in the general population and for 35‐40% in the setting of human immunodeficiency virus (HIV) infection. The authors report a 9‐year single‐institution experience with 75 adult BL patients (46 with and 29 without HIV infection) and compare the clinical and pathologic features of the disease in the two groups of patients.
What Drives Interregional Bank Branch Closure? The Case of Japan's Regional Banks in the Post‐Deregulation Period

Since the elimination of branch restrictions in the Japanese banking sector, the number of interregional branches closing has exceeded that of new branches being established. By analyzing branch data covering 2000–2012, we find that the probability of interregional branch closures is higher than that of intraregional branch closures because interregional branching worsens banks’ cost efficiency. Further, we show that the geographical distance between branches does not increase the probability of intraregional branch closures, but it does raise the probability of interregional branch closures. Moreover, banks that focus on SME markets have a higher probability of closure in interregional markets than those that focus on household loan markets.
Ten Questions About Why and How to Tax the Digitalized Economy

Much work has been done by international organizations, tax scholars around the world and business experts on the future shape of the taxation of the digitalized economy. Starting from the assumption that any “ring-fencing” of the digitalized economy should be avoided, it is far from easy to develop a framework in the context of the corporate income tax to capture profits derived by cross-border digital transactions in an orderly way. General notions like “economic allegiance”, the “benefit principle” or “digital presence” are unhelpful when it comes to sharing the pie between production countries and destination countries. Empowering the market countries can follow two different trajectories: a set of rules based on the notion of “digital presence” which simply looks to the demand side of the market, or a set of rules based on the notion of “digital investment” as a proxy for a productive source of income set-up by the taxpayer in regard of the market. While these pathways should be explored in the next couple of years, any search for a “quick fix” might not only be distortive and inefficient, it might also stand in the way of a new international consensus built around a new set of overall tax principles. Temporary measures might easily translate into permanent measures. Anybody who attempts to introduce specific tax treatment for the digitalized economy should be as transparent as possible with regard to the ten major policy questions outlined in this article.
Renal anomalies in Alagille syndrome: A disease‐defining feature

Alagille syndrome (ALGS) is an autosomal dominant condition, primarily caused by mutations in JAGGED1. ALGS is defined by cholestatic liver disease, cardiac disease and involvement of the face, skeleton, and eyes with variable expression of these features. Renal involvement has been reported though not formally described. The objective of this study was to systematically characterize the renal involvement in ALGS. We performed a retrospective review of 466 JAGGED1 mutation‐positive ALGS patients. Charts were reviewed for serum biochemistries, renal ultrasounds or other imaging, urinalysis, and clinical reports from pediatric nephrologists. The clinical data were reviewed by two pediatric hepatologists and a pediatric nephrologist. Of 466 charts reviewed we found 187 yielded evaluable renal information. Of these, 73/187 were shown to have renal involvement, representing 39% of the study cohort. Renal dysplasia was the most common anomaly seen. Genotype analysis of the JAGGED1 mutations in the patients with and without renal involvement did not reveal an association with mutation type. From the study we concluded that renal involvement has a prevalence of 39% in ALGS in our evaluable patients. Renal dysplasia is the most common renal anomaly. This finding correlates with the known role of the Notch pathway in glomerular development. Since renal disease of the type seen in ALGS can impair growth and impact liver transplantation, there is a clear need for a prospective study of renal involvement in ALGS and the development of guidelines for evaluation and management. These data also suggest that renal involvement be considered the sixth defining criterion for ALGS. © 2011 Wiley Periodicals, Inc.
Energy system contribution to 400-metre and 800-metre track running

As a wide range of values has been reported for the relative energetics of 400-m and 800-m track running events, this study aimed to quantify the respective aerobic and anaerobic energy contributions to these events during track running. Sixteen trained 400-m (11 males, 5 females) and 11 trained 800-m (9 males, 2 females) athletes participated in this study. The participants performed (on separate days) a laboratory graded exercsie test and multiple race time-trials. The relative energy system contribution was calculated by multiple methods based upon measures of race [Vdot]O2, accumulated oxygen deficit (AOD), blood lactate and estimated phosphocreatine degradation (lactate/PCr). The aerobic/anaerobic energy system contribution (AOD method) to the 400-m event was calculated as 41/59% (male) and 45/55% (female). For the 800-m event, an increased aerobic involvement was noted with a 60/40% (male) and 70/30% (female) respective contribution. Significant (P < 0.05) negative correlations were noted between race performance and anaerobic energy system involvement (lactate/PCr) for the male 800-m and female 400-m events (r = − 0.77 and − 0.87 respectively). These track running data compare well with previous estimates of the relative energy system contributions to the 400-m and 800-m events. Additionally, the relative importance and speed of interaction of the respective metabolic pathways has implications to training for these events.
Ultrasonographic biomicroscopy, Scheimpflug photography, and novel provocative tests in contralateral eyes of Chinese patients initially seen with acute angle closure.

OBJECTIVES To compare ocular biometry of the contralateral eyes of individuals seen with acute angle closure (AAC) with eyes of population-based control subjects, and to assess novel provocative tests to study the mechanism of AAC. DESIGN Prospective case-control study. PARTICIPANTS Chinese persons seen as incident cases of AAC and Chinese population-based controls. METHODS Slitlamp assessment, ultrasonographic biomicroscopy, Scheimpflug photography, and provocative testing were performed. MAIN OUTCOME MEASURES Ocular biometric parameters including anterior chamber depth, limbal anterior chamber depth, axial length, lens thickness, and radius of corneal curvature were obtained. Ultrasonographic biomicroscopy parameters that include the angle-opening distance at 500 micro m and the angle-recess area were noted. Scheimpflug photography produced a single measure of angle width. RESULTS Contralateral eyes of cases of AAC had shorter axial lengths, shallower anterior chamber depths, thicker lenses, and steeper radii of corneal curvature (P<.01). After adjusting for age and sex, cases had a mean adjusted axial length that was 1.2 mm shorter, an optical anterior chamber depth that was 0.63 mm shallower (24% shallower than controls), and lenses that were, on average, 0.35 mm thicker (P<.01). Furthermore, using multiple logistic regression to adjust for age and sex, patients with primary angle-closure glaucoma were 19 times as likely to have a shallower limbal anterior chamber depth (25%; 95% confidence interval, 8.3-45.2). Adjusting for age and sex, the mean angle-opening distance at 500 microm was 0.14 U less for cases, with a mean of 0.26 U in controls, making the angle-opening distance at 500 microm, on average, 54% less among cases. Scheimpflug photographs revealed an adjusted angle width of 21.6 degrees for controls and 15.1 degrees for cases (P<.05). Dynamic testing showed that the angle of control eyes tended to shallow less when going from light to dark and tended to open more when given 1 drop of pilocarpine hydrochloride. CONCLUSIONS Contralateral eyes of individuals having an AAC attack tend to be shorter and have more crowded anterior segments than those of healthy controls. These static measures of ocular biometry indicate why some individuals are predisposed to AAC. Dynamic measures of the response to luminance changes and pilocarpine therapy indicate that differential reactions to these stimuli are also associated with an AAC attack.
The Watchdog or the Mandarin? Assessing the impact of the Directorates General on the EU legislative process

ABSTRACT This article assesses the role of the Directorates Generals (DGs) led by the Commissioners in the EU legislative decision-making by testing two perspectives: ‘the Watchdog’ and ‘the Mandarin’ of the EU principals. The former suggests that a conflict of preferences between the DGs will notify the EU principals of prospective bureaucratic drift, leading to more restrictive discretionary limits imposed on the Commission in the implementation stage. However, if the lead DG acts as the Mandarin, proximity of its preference to the EU principals should result in more executive leeway as its policy preference is more beneficial for the EU legislators. To tests the conjunctions, this study focuses on two dimensions of EU political space: Left-Right (LR) and Pro/Anti-EU. The results suggest that the legislators will indulge the Commission with more leeway for the implementation when their preferences are more congruent with the position of the lead DG on the LR dimension, thus supporting ‘the Mandarin’ perspective.
The Interaction between Impaired Acute Insulin Response and Insulin Resistance Predict Type 2 Diabetes and Impairment of Fasting Glucose

Background: Impaired acute insulin response (AIR) and insulin resistance (IR) are characteristics of Type 2 diabetes (T2DM). The aim was to develop risk models for T2DM and impaired fasting glucose (IFG), reflecting estimates both of AIR and IR, and of their interaction, as predictors over 20 years of follow-up. Methods: We developed predictive models using hierarchic multiple regression analyses in a population-based cohort of 1227 men with normal fasting blood glucose at baseline (1970-73) and were reinvestigated after 10 and after 20 years. Using IVGTT-variables correlated either to AIR or to IR, separate models were developed. Combined models were also estimated from which prediction scores, representing individual risk, were calculated. Results: In combined models, interaction between prediction scores reflecting AIR and IR predicted T2DM and IFG. Lowest tertile of AIR and the highest tertile of IR showed a relative risk (RR) of 15.3 (95%-CI=5.58-41.84) for T2DM compared to the contrast group (high AIR and low IR). Corresponding RR for IFG was 13.23 (95%-CI=6.53-26.78). C-statistic increased from 0.76 to 0.79 (p=0.018) for T2DM and from 0.77 to 0.80 for IFG (p=0.062) taking interaction into account. Main effects of lowest tertile of AIR and highest tertile of IR versus best were: RR for T2DM, 8.80 (95%-CI=4.25-18.21) and 6.31 (95%-CI=3.26-12.21); for IFG, 9.07, (95%-CI=5.38-15.29) and 4.49 (95%-CI=2.98-6-76). Conclusion:. The interaction between low AIR and high IR revealed a high relative risk for T2DM or IFG reflecting the interplay between these factors over long time on worsening glucose tolerance and development of manifest disease.
