Evolving Gene Expression Programming Classifiers for Ensemble Prediction of Movements on the Stock Market

Forecasting applications on the stock market attract much interest from researchers in the artificial intelligence field. The problem tackled in this study concerns predicting the direction of change of stock price indices, formulated in terms of binary classification. We use gene expression programming to evolve pools of binary classifiers and investigate several approaches to construct ensembles based on them. We compare the performance of the obtained classifiers with those of Naive Bayes, Support Vector Machines, Multilayer Perceptron, Decision Table and Random Forrest. The experiments performed on real-world stock market data show that the ensembles of GEP-evolved classifier models are competitive to classifiers trained by state-of-the-art machine learning methods.
Growth parameters of NICU admitted low birth weight preterm neonates at corrected ages of 6 and 12 month

Background: Low birth weight (LBW or birth weight <2500 g) is one of the most serious health problems in today's world. Objective: The purpose of this study was to evaluate growth parameters of neonatal intensive care unit (NICU) admitted LBW preterm neonates at corrected ages of 6 and 12 months. Materials and Methods: In a prospective cohort (follow up) study, all LBW preterm neonates whom were admitted to Shahid Sadoughi Hospital NICU in 2008, followed up for one year and their weight, height and head circumference evaluated at ages of 6 and 12 months. Results: Twenty four boys and 26 girls with mean gestational age of 31.3±2.7 weeks and mean birth weight of 1480.3±422.8gr were evaluated. The most frequency of underweight and short stature was seen at the age of six months. Exclusive breast feeding infants had the lowest frequency of underweight at the age of six. Frequency of underweight at the age of six months and NICU stay days were more in neonates with birth weight of less than 1000 gr. Conclusion: It is necessary to emphasize on the importance of growth assessment of LBW children and proper education of their mothers about nutrition of their children for early and timely diagnosis and management of growth retardation and prevention of subsequent problems.
How to use indistinguishability obfuscation: deniable encryption, and more

We introduce a new technique, that we call punctured programs, to apply indistinguishability obfuscation towards cryptographic problems. We use this technique to carry out a systematic study of the applicability of indistinguishability obfuscation to a variety of cryptographic goals. Along the way, we resolve the 16-year-old open question of Deniable Encryption, posed by Canetti, Dwork, Naor, and Ostrovsky in 1997: In deniable encryption, a sender who is forced to reveal to an adversary both her message and the randomness she used for encrypting it should be able to convincingly provide "fake" randomness that can explain any alternative message that she would like to pretend that she sent. We resolve this question by giving the first construction of deniable encryption that does not require any pre-planning by the party that must later issue a denial. In addition, we show the generality of our punctured programs technique by also constructing a variety of core cryptographic objects from indistinguishability obfuscation and one-way functions (or close variants). In particular we obtain: public key encryption, short "hash-and-sign" selectively secure signatures, chosen-ciphertext secure public key encryption, non-interactive zero knowledge proofs (NIZKs), injective trapdoor functions, and oblivious transfer. These results suggest the possibility of indistinguishability obfuscation becoming a "central hub" for cryptography.
Nutritional Status and Associated Factors among Pregnant Women in Wondo Genet District, Southern Ethiopia

Inadequate quality and quantity diet is one of the major reasons for high levels of malnutrition in pregnant women. A cross-sectional survey was conducted in Wondo Genet District, Southern Ethiopia. A two-stage cluster sampling technique was used to select a representative sample of 153 pregnant women aged 19-49 years from three rural villages (“Kebeles”). Energy and nutrient intakes from foods were calculated from one-day weighed food records on a sub-sample (n = 77). The result of the study showed that the intakes of most nutrients were lower than the recommended intake. The energy intake of the study participants both in 2nd and 3rd trimesters of pregnancy were 2,308 kcal and 1,420.5 kcal compared to the recommended 2,340 kcal and 2,452 kcal, respectively. Except iron, almost all micronutrient intakes were lower than the recommended intake. Vitamin A intake was 3 μg compared with the recommended 800 μg, while protein intake of the study respondents in 2nd and 3rd trimester of pregnancy was 45.9 g and 31.5 g, respectively, compared with the recommended 71 g. Risk factors for undernutrition were multiple pregnancy and no consumption of cereal-based foods. This study revealed that the energy and nutrient intake of the pregnant women in study area was below the recommended intakes. Furthermore, the situation might be aggravated by high phytate content food consumption reported. Nutritional status of pregnant women in study area was not adequate to support the increased energy and nutrient requirement of the participants.
Cancer incidence among physicians occupationally exposed to ionizing radiation in Finland.

OBJECTIVES Occupational radiation exposure was estimated, and the cancer incidence among physicians working with radiation was compared to that of unexposed physicians. METHODS A cohort of 1312 physicians was identified from the Finnish occupational radiation exposure registry. Radiation exposure data were obtained from 1970 to 2001 on the basis of individual dosimeters. Never-monitored Finnish physicians (N=15 821) were used as a reference group, identified from census data of Statistics Finland. Incident cancer cases were identified by record linkage with the Finnish Cancer Registry. RESULTS The cumulative radiation dose exceeded the recording level (0.3-3.0 mSv during a 3-month period for 1029 radiation-exposed physicians (59.8%). Six percent of the radiologists had received a cumulative dose of 50 mSv or more. Altogether there were 41 cancers observed among the radiation-exposed physicians and 998 cases found in the never-monitored group. Standardized incidence ratios (SIR) for all cancers were comparable with those of the general population among physicians monitored for radiation [SIR 1.0, 95% confidence interval (95% CI) 0.7-1.4] and other physicians (SIR 1.0, 95% CI 1.0-1.1). For specific cancer sites, a slightly elevated risk of female breast cancer was found among monitored physicians when compared with other physicians (rate ratio 1.7, 95% CI 1.0-3.1). No obvious dose-response relationship was found for the overall cancer incidence. CONCLUSIONS According to the results from a nationwide cohort, occupational exposure to medical radiation is not a strong risk factor for cancer among physicians. Possible excess risk could not be reliably demonstrated even after the follow-up of a nationwide cohort for up to 30 years.
Outdoor Air Pollution and Incidence of Ischemic and Hemorrhagic Stroke: A Small-Area Level Ecological Study

Background and Purpose— Evidence linking outdoor air pollution and incidence of stroke is limited. We examined effects of outdoor air pollution on the incidence of ischemic and hemorrhagic stroke at the population level focusing on middle-aged and older people. Methods— We used a small-area level ecological study design and a stroke register set up to capture all incident cases of first-ever stroke occurring in a defined geographical area in south London (948 census output areas) where road traffic contributes to spatial variation in air pollution. Population-weighted averages were calculated for output areas using outdoor nitrogen dioxide and PM10 concentrations modeled at a 20-m resolution. Results— There were 1832 ischemic and 348 hemorrhagic strokes in 1995 to 2004 occurring among a resident population of 267 839. Mean (SD) concentration was 25.1 (1.2) &mgr;g/m3 (range, 23.3–36.4 &mgr;g/m3) for PM10 and 41.4 (3.0) &mgr;g/m3 (range, 35.4–68.0 &mgr;g/m3) for nitrogen dioxide. For ischemic stroke, adjusted rate ratios per 10-&mgr;g/m3 increase, for all ages, 40 to 64 and 65 to 79 years, respectively, were 1.22 (0.77–1.93), 1.12 (0.55–2.28), and 1.86 (1.10–3.13) for PM10 and 1.11 (0.93–1.32), 1.13 (0.86–1.50), and 1.23 (0.99–1.53) for nitrogen dioxide. For hemorrhagic stroke, the corresponding rate ratios were 0.52 (0.20–1.37), 0.78 (0.17–3.51), and 0.51 (0.12–2.22) for PM10 and 0.86 (0.60–1.24), 1.12 (0.66–1.90), and 0.78 (0.44–1.39) for nitrogen dioxide. Conclusions— Although there was no significant association between outdoor air pollutants and ischemic stroke incidence for all ages combined, there was a suggestion of increased risk among people aged 65 to 79 years. There was no evidence of increased incidence in hemorrhagic stroke.
Las competencias y el uso de las Tecnologías de Información y Comunicación (TIC) por el profesorado: estructura dimensional

This article presents the results of a study on the competencies possessed by the faculty of elementary-school and junior-high-school teachers (of compulsory and post-compulsory education) in Valencia (Spain), as concerning the use of Information and Communication Technologies ( ICT ) . We worked with a stratified random sample of 868 teachers, and analyzed their competencies in two areas: personal-professional use, and the use they make of ICT in the classroom. Although the study is based on various analyses, its contribution to Categorical Principal Components Analysis ( CATPCA ) should be emphasized for the dimensional analysis and determination of the relationship of these dimensions with other variables of interest. The paper contributes results of interest as regards planning the integration of ICT into schools, as well as pertaining to teacher training for the pedagogical integration of ICT .
Connectionist Models and Cognitive Theory

Connectionist models have come to play an important role in cognitive science and in cognitive neuroscience, yet their role in explaining behavior is not necessarily obvious and has generated considerable debate. Connectionism is a body of tools and ideas that can be used in different ways. It can be treated as a form of simulation modeling in which the goal is to implement preexisting theories. In this approach, connectionist models function as a kind of statistical tool, a way of analyzing a complex set of data. Connectionism can also be seen as providing a small set of general theoretical principles that apply in a variety of domains. Construed in this way, it contributes to the development of theories that are explanatory, not merely descriptive.
Spatial heterogeneity of dengue fever in local studies, City of Niterói, Southeastern Brazil.

OBJECTIVE To analyze the spatial and temporal occurrence of dengue fever and its association with the heterogeneity of urban environment characteristics. METHODS A total of 1,212 dengue cases, recorded in the Information System for Notifiable Diseases (Sinan) between 1998 and 2006, in the city of Niterói, Southeastern Brazil, were georeferenced according to census tracts. These tracts were classified into homogeneous areas for the occurrence of the disease: slum, shipyard and urban area. Cases were grouped into five periods--two inter-epidemic periods (1998-2000 and 2003-2005) and three epidemic periods (2001, 2002 and 2006)--and analyzed using operations between layers in a geographic information system (GIS) environment. The kernel method was used to identify clusters of cases. Kulldorff's spatial scan statistic was used to confirm these clusters statistically. RESULTS Of all cases, 57% were females. Age groups with the highest number of cases were 20-29-years (20.5%) and 30-39-years (17.7%). The hill slum sector showed only 11% of households covered by garbage collection service, the highest percentage of illiterate individuals (8.7%) and head of families with income lower than one monthly minimum wage (29.5%). Cases remained in the slum sectors. In the first epidemic year and in the inter-epidemic periods, the highest number of cases was found in the hill and flatland slum sectors; in the second and third epidemic years, in the flatland slum sector. CONCLUSIONS The economically active portion of the population was that most affected in the study area. Census tracts show spatial heterogeneity in relation to life conditions. In addition, in some tracts, there are differences in spatial and temporal distribution of the risk of occurrence of dengue fever.
LIGOPHORUS PILENGAS N. SP. (MONOGENEA: ANCYROCEPHALIDAE) FROM THE INTRODUCED SO-IUY MULLET, MUGIL SOIUY (TELEOSTEI: MUGILIDAE), IN THE SEA OF AZOV AND THE BLACK SEA

The monogenean Ligophorus chabaudi was originally described on the gills of the flathead mullet, Mugil cephalus, and was subsequently reported on the So-iuy mullet, Mugil soiuy. However, the morphology of sclerotized parts and multivariate statistical analyses suggest that the form from the So-iuy mullet represents a new species. This study provides a description of the new species Ligophorus pilengas n. sp. and provides additional morphological data concerning the morphology of the ventral bar that might be useful for the diagnosis of Ligophorus. Ligophorus pilengas n. sp. is the second species of Ligophorus reported on the So-iuy mullet. Zoogeographical records indicate that L. pilengas n. sp. was probably introduced to the Black Sea and the Sea of Azov from the western Pacific Ocean together with its host.
Plasma MicroRNA, a Potential Biomarker for Acute Rejection After Liver Transplantation

Background Acute rejection (AR) of an organ transplant is a life-threatening complication. Currently, there are few diagnostic biomarkers suitable for clinical application. We aim to determine the potential of plasma microRNAs as biomarkers for AR. Methods Using rat orthotopic liver transplantation model and microarrays, we compared the difference in the spectrum and levels of microRNAs in both plasma and grafts between AR rats and control. AR-related plasma microRNAs were selected and validated using real-time quantification polymerase chain reaction. Plasma from AR rats with or without tacrolimus treatment was used for microRNA dynamic monitoring. To clarify the origin of AR-related plasma microRNAs, drug-induced liver damage rat model were performed and in situ hybridization was used to detect and localize the specific microRNA in allografts. Results We found that plasma miR-122, miR-192, and miR-146a was significantly up-regulated when AR occur (fold change>2; P<0.05) and the elevation could be repressed by immunosuppression. In liver injury rat model, up-regulated plasma miR-122 (fold change=22.126; P=0.002) and miR-192 (fold change=8.833; P<0.001) rather than miR-146a (fold change=1.181; P=0.594) were observed. Further study demonstrated that miR-146a was up-regulated by sixfold in microvesicles isolated from AR plasma, whereas miR-122 and miR-192 showed no distinct change. In situ hybridization revealed that the portal areas of the AR graft were brimming with lymphocytes, which showed highly intense staining for miR-146a. Conclusions Our study provides the global fingerprint of plasma microRNAs in AR rats and suggests that plasma miR-122 and miR-192 reflect liver injury, whereas miR-146a may associate with cellular rejection.
The Impact of Choice on EFL Students' Motivation and Engagement with L2 Vocabulary Learning.

The current study investigates EFL college learners’ motivation and engagement during English vocabulary learning tasks. By adopting self-determination theory (SDT; Deci & Ryan, 1985, 2000), the study looked into the impact of autonomy on college students’ task motivation and engagement with vocabulary learning tasks and their general English learning motivation (i.e. trait motivation). Changes in task motivation over 14 weeks of research were also investigated. The results of quantitative analyses obtained from questionnaires and observations over 14 weeks uncovered that the participants who were given the freedom to choose their own target words showed higher task motivation and task engagement than those who were required to learn pre-selected target words. Learners’ general attitude toward English learning, however, was not influenced by the provision of choice in the vocabulary learning tasks. The 14-week experimental research also depicts the changes of task motivation and engagement over time. Even with the same settings and task procedures, learners’ task motivation fluctuated. In accordance with SDT, the findings in the present study support the importance of creating autonomy-supportive vocabulary learning tasks.
The dual diagnosis of attention-deficit/hyperactivity disorder and substance abuse: case reports and literature review.

BACKGROUND It is now recognized that attention-deficit/hyperactivity disorder (ADHD) may persist into adulthood. A number of studies have found an association between ADHD and substance abuse. This article describes three adult patients with both ADHD and substance abuse who were treated successfully with psychostimulants. A review of the relevant literature is included. METHOD The patients were drawn from a university-based referral center for adults with ADHD. Evaluations for ADHD and substance abuse were completed. Medical therapy and follow-up were completed by the first author. RESULTS All of the patients responded to psychostimulants and have remained abstinent from alcohol and other drugs for the past 2 to 3 years. CONCLUSION This case series and review of the literature suggest that specific treatment for ADHD with psychostimulants is feasible in patients who also have substance abuse. Future studies should evaluate the prevalence of this "dual diagnosis" and the efficacy of differing management strategies.
Changes in Allergen Sensitization Over The Last 30 Years in Korea Respiratory Allergic Patients: A Single-Center

Purpose Determining the culprit allergen is important for the diagnosis and management of allergic diseases. The skin prick test (SPT) has been widely used to identify culprit allergens. Skin reactivity to allergens has changed due to changes in lifestyle and outdoor environments. Therefore, the aim of the present paper was to examine changes in allergen sensitization in Korea. Methods We enrolled 1,135 patients with respiratory allergic diseases who were diagnosed at Severance Hospital from January 2010 to December 2011. SPTs were performed with inhalant allergens, and were compared to our previous studies of the SPTs in the 1980s and the 1990s. Results In the 2010s, the SPT positive rate of allergic rhinitis or allergic conjunctivitis was higher than asthma without allergic rhinitis or allergic conjunctivitis. The SPT positive rate was decreased by increments of age (P value <0.01). Skin reactivity to tree pollens was significantly increased to 36.4% in the 2010s from 19.0% in the 1990s and 8.8% in the 1980s. Among tree pollens, skin reactivity to oak (4.7%->14.4%), birch (7.1%->13.6%), alder (6.3%->13.4%) and pine (2.9%->14.3%) was significantly increased in the 2010s compared with the 1990s, respectively. Current skin reactivity to grass pollens (13.9%) and weed pollens (27.0%) has significantly decreased since the 1990s (20.3%, 40.9%, respectively). Skin reactivity to house dust mites showed no difference between the 1990s (55.2%) and the 2010s (55.6%). Skin reactivity to dog (27.3%->20.7%) and cockroach (25.3%->12.3%) have significantly decreased in the 2010s in comparison with the 1990s. Conclusions In light of the above results, we revealed the changes in skin reactivity to inhalant allergens that have occurred in Korean allergic patients over the past three decades. Since outdoor environmental factors such as the amount of pollen, global warming and plant distribution causes the changes in skin reactivity, further study and continuous close observation will be needed.
Transfer bi-directional LSTM RNN for named entity recognition in Chinese electronic medical records

In this paper, a transfer bi-directional recurrent neural networks (RNN) is proposed for named entity recognition (NER) in Chinese electronic medical records (EMRs) that aims to extract medical knowledge such as phrases recording diseases and treatments automatically. We propose a two-step procedure where the first step is to train a shallow bi-directional RNN in the general domain, and the second step is to transfer knowledge from the general domain to train a deeper bi-directional RNN for recognizing medical concepts from Chinese EMRs. Specifically, this is achieved by initializing the shallow parts of the deeper network in the second step with parameter weights from the bi-directional RNN trained in the first step. Then the deeper networks are re-trained on the Chinese EMRs. Experimental results show that NER performances are improved by the transferred knowledge significantly.
Ovulatory Function in Epilepsy

Summary Women with epilepsy have lower fertility rates than women without epilepsy. We hypothesized that limbic dysfunction in temporal lobe epilepsy (TLE) alters the release of hypothalamic trophic hormones that secondarily affect release of the pituitary gonadotropins, causing ovulatory failure. We assessed ovulatory function over three consecutive menstrual cycles in 17 women with partial seizures arising from the temporal lobe (TLE), 7 women with primary generalized epilepsy (PGE), and 12 controls. We devised scores to reflect ovulatory function that were based on daily basal body tem perature and monthly serum progesterone levels. Seizure frequency, antiepileptic drugs (AEDs), and depressive symptomatology were also evaluated. Anovulation was more frequent in subjects with TLE (35.3%) than in subjects with PGE (0%) or in controls (8.3%). Anovulatory cycles tended to occur more frequently in subjects with TLE who were treated with polytherapy than in those receiving monotherapy, but this result was not statistically significant. Seizure frequency and symptoms of depression did not affect ovulatory function. Although AED polytherapy may increase the likelihood of anovulation, our results suggest a mechanism of infertility related to temporal lobe dysfunction.
