Comparative analysis of the discriminative capacity of EEG, two ECG-derived and respiratory signals in automatic sleep staging

Highly accurate classification of sleep stages is possible based on EEG signals alone. However, reliable and high quality acquisition of these signals in the home environment is difficult. Instead, electrocardiogram (ECG) and Respiratory (Res) signals are easier to record and may offer a practical alternative for home monitoring of sleep. Therefore, automatic sleep staging was performed using ECG, Res (thoracic excursion) and EEG signals from 31 nocturnal recordings of the Sleep Heart Health Study (SHHS) polysomnography Database. Feature vectors were extracted from 0.5 min (standard) epochs of sleep data by time-domain, frequency domain, time-frequency and nonlinear methods and optimized by using the Support Vector Machine-Recursive Feature Elimination (SVM-RFE) method. These features were then classified by using a SVM. Classification based upon EEG features produced a Correct Classification Ratio CCR=0.92. In comparison, features derived from ECG signals alone, that is the combination of Heart Rate Variability (HRV), and ECG-Derived Respiration (EDR) signals produced a CCR=0.54, while those features based on the combination of HRV and (thoracic) Res signals resulted in a CCR=0.57. Overall comparison of the results based on standard epochs of EEG signals with those obtained from 5-minute (long) epochs of cardiorespiratory signals, revealed that acceptable CCR=0.81 and discriminative capacity (Accuracy=89.32%, Specificity=92.88% and Sensitivity=78.64%) were also achievable when using optimal feature sets derived from long epochs of the latter signals in sleep staging. In addition, it was observed that the presence of some artifacts (like bigeminy) in the cardiorespiratory signals reduced the accuracy of automatic sleep staging more than the artifacts that contaminated the EEG signals.

The Impact of Family Supportive Supervisor Behavior on Employee’s Proactive Behavior: A Study of a Moderated Mediating Effect

Based on the theory of social exchange, this study attempts to probe the mechanism of the impact of the family supportive supervisor behavior on employee’s proactive behavior, especially to explore the mediating role of the affective commitment and the moderating role of the power distance in Chinese organizational context. After analyzing the samples collected from 305 employees, we found that: family supportive supervisor behavior has a significantly positive effect on employee’s proactive behavior; affective commitment plays a partial mediating role between family supportive supervisor behavior and employee’s proactive behavior; meanwhile, power distance moderates the relationship between family supported supervisory behavior and affective commitment, and further moderates the indirect relationship between family supported supervisory behavior and employee’s proactive behavior through affective commitment. That is, the lower the employees’ power distance is, the stronger the mediating effect of affective commitment becomes.
A comparative analysis of the impact of current account balances on economic growth of sane countries

This study investigates the impact of current account balance on economic growth in SANE countries which comprises of South Africa, Algeria, Nigeria and Egypt. A comparative study is conducted on the impact which current account balance has on each country’s economic growth. Various theoretical expositions have led to contradictory conclusions on the impact which current account balance has on economic growth. To achieve the objective of this study, ARDL estimation technique is employed to investigate the comparative analysis and fully modified panel OLS (FMOLS) is employed to investigate the overall impact of current account balance on economic growth. It was discovered from the study that current account balance has a significant negative impact on economic growth for Algeria, Egypt and Nigeria while it has a significant positive impact on economic growth for South Africa. The implication of this finding is that the structure of an economy with respect to her main source of foreign exchange earnings determines the impact of such activities reflected by her current account balance on the country’s economic growth. It is therefore recommended that special attention should be paid to the diversification of the export base. This can principally be through technological innovations, agriculture and so on. Therefore, the mitigation or neutralization of the effect of any short fall or negative shock in the oil sectors can only be achieved by the implementation of reforms and policies that will reduce dependence on oil and promote dependence on the non oil sectors.

Obesity Management The influence of high-intensity interval training on anthropometric variables of adults afflicted with overweight or obesity : a systematic review and network meta-analysis

E-mail: vidal.leo@hotmail.com Summary Objective: The goal of this study was to evaluate the influence of high-intensity interval training (HIIT) on anthropometric variables in adults afflicted with overweight or obesity and to compare the effects with those of moderate-intensity continuous training. Methods: A computer literature search was performed for HIIT intervention studies that evaluated anthropometric variables in adults afflicted with overweight or obesity. Results: Of the 857 articles retrieved in the electronic search, 48 met the inclusion criteria. The analyses demonstrated that HIITwas effective in decreasing body mass ( 1.45 kg [95% CI: 1.85 to 1.05 kg]), body mass index ( 0.44 kg m 2 [95% CI: 0.59 to 0.30 kg m ]), waist circumference ( 2.3 cm [95% CI: 3.1 to 1.4 cm]), waist/hip ratio ( 0.01 [95% CI: 0.02 to 0.00]), body fat percentage ( 1.29% [95% CI: 1.70% to 0.87%]) and abdominal visceral fat area ( 6.83 cm [95% CI: 11.95 to 1.71 cm]). When considering equalization between the two methods (energy expenditure or workload matched), no differences were found in any measure except body mass (for which HIIT was superior). Conclusions: High-intensity interval training and moderate-intensity continuous training results were similar, particularly when equalization between the two methods was considered. Thus, HIIT can be used as a secondary method for the treatment of obesity in adults.
LINGUISTIC INTERCOURSE WITH SPATIAL PERCEPTION COMPARATIVE ANALYSIS IN PRIMARY SCHOOL, INFANT SCHOOL AND THE FAMILY

A lot of mathematical abilities as well as general cognitive abilities have come to be understood in the context of spatial perception. According to Newcombe and Huttenlocher (2006), a key aspect of improving spatial-geometrical ability lies in the linguistic coding of space – yet this linguistic intercourse with spatial perception remains unfulfilled. Research in the field of mathematics education indicates that this can be explained by a tendency to interpret situations in arithmetical terms, or to employ more deictically characterised, implicit forms of mediation. The following paper presents a video-based empirical study currently being carried out, which attempts to reconstruct and compare linguistic intercourse with spatial perception in different places children learn – in infant school, primary school, and the family.
The Effect of Extensive Reading Exercise on EFL Learners ’ Incidental Vocabulary Acquisition

The focus of this thesis was to examine whether extensive reading with vocabulary enhanced exercises could enhance Iranian EFL learners ' incidental vocabulary acquisition. It also monitors whether students have positive attitudes towards enhancing words incidentally through extensive reading. The subjects were 30 EFL female at a language institute in Mazandaran. Their ages varied from 13 to 14. They were randomly divided into a control group (N = 15) and experimental group (N = 15). The experimental group received an ER Plus treatment, whereas the control group experienced an ER Only treatment. In order to examine the thesis questions, a set of vocabulary tests and questionnaires were administered before and after the treatments (ER programs). The vocabulary test was used to measure the increases if any in the students’ vocabulary size, whereas the affective questionnaire was used to measure the learners’ attitudes and beliefs towards the incorporation of an ER program into their reading course. Results of independent samples t-test revealed that ER can enhance vocabulary acquisition both incidentally and when incorporated in vocabulary enhancement activities. Besides, results of one-sample t-test indicated that ER can promote positive attitudes toward reading in English and learning vocabulary through reading. Introduction For a long time, reading and second language development has been assumed to have a mutual relationship. Second language development allows students to read in the second language, but reading in the second language also fuels second language development. In other words, learners learn to read and read to learn. Most studies on reading (Coady, 1997; Bell, 1998; 2001) describe how reading aids in language development – specifically how reading helps learners to acquire knowledge, broaden understanding, and develop knowledge of vocabulary. Vocabulary is also a fundamental component in second language development. According to Grabe and Stoller (1997), vocabulary is an essential requirement for the necessary prerequisite for reading extensively in the target language. EFL reading instruction at school level is usually presented in the form of intensive reading. This refers to “the careful reading of shorter, more difficult texts with the goal of complete and detailed understanding. Intensive reading is also associated with the teaching of reading in terms of its component skills” (Bamford & Day, 1997, p. 6). According to Susser and Robb (1990), “Such a pedagogic practice may be justified as a language lesson, but not as a reading lesson. Intensive reading is actually not reading at all. ” This justifies the fact that most Iranian EFL students are not at all fluent
Polychaetes of Antarctic sublittoral in the proglacial zone ( King George Island , South Shetland Islands )

Ninety eight polychaete species were found in the shallow sublittoral of Ad− miralty Bay. The most abundant were Leitoscoloplos kerguelensis, Tauberia gracilis, Ophelina syringopyge, Rhodine intermedia, Tharyx cincinnatus, Aricidea (Acesta) strel− zovi, Apistobranchus sp. , Cirrophorus brevicirratus and Microspio moorei. Mean abun− dance of polychaetes was estimated at 120 ind. / 0.1m2. As a result of cluster analysis several polychaete assemblages were distinguished. The highly specific assemblage with two char− acteristic species, Scoloplos marginatus and Travisia kerguelensis, from shallow areas with sandy bottom situated far from glaciers; a distincly specific assemblage with Apisto− branchus sp. from poorly sorted sediments in the bottom areas situated on the slopes at the base of steep rubble shores; the richest and most diverse, highly specific polychaete assem− blage from the central basin of the bay with Tauberia gracilis as the most characteristic spe− cies, as well as two assemblages from the bottom areas neighbouring glaciers and influ− enced by the intensive enrichment of very small grain−sized sediments with Ophelina cylindricaudata and Tharyx cincinnatus. Clear assemblages’ arrangement was observed along the gradient: sand, silty sand, silt towards clay silt. Other important factors, support− ing the proposed classification of assemblages and their character, include the sorting coef− ficient of the sediment (So) as well as the slope of the bottom. The between−habitat diversity of polychaete fauna is strongly connected with the phenomena occurring in the neighbouring terrestrial coastal areas.
In situ measurements of cirrus ice water content ( IWC ) by the Harvard water vapor and total water instruments during Cirrus Regional Study of Tropical Anvils and Cirrus Layers-Florida Area Cirrus Experiment

[1] In situ measurements of cirrus ice water content (IWC) by the Harvard water vapor and total water instruments during Cirrus Regional Study of Tropical Anvils and Cirrus Layers-Florida Area Cirrus Experiment are compared with remote sensing data made by the Cloud Radar System instrument in order to derive and validate an empirical IWC-radar relflectivity Ze relationship. The comparisons show that for measurements of in situ IWC and remotely measured radar reflectivity, collocated within 2 km of each other, a single IWC-Ze relationship can be found that fits the data with an uncertainty of ±20–30%. A cloud resolving model shows this level of uncertainty to be consistent with sampling errors associated with comparing two measurements that are not collocated. Uncertainties are quantified in the use of in situ data to validate the retrieval algorithms used to derive the IWC of clouds from remote sensing observations, such as radar reflectivity Ze. Uncertainties are classified into instrumental uncertainties, uncertainties related to sampling errors, and uncertainties in using a single IWC-Ze relationship to describe a cloud.
TARGETING STAT 3 IN CANCER INHIBITION

Signal transducer and activator of transcription 3 (STAT3) regulates many critical functions in human normal and malignant tissues, such as differentiation, proliferation, survival, angiogenesis and immune function. Constitutive activation of STAT3 is implicated in a wide range of human cancers. As such, STAT3 has been studied as a tumor therapeutic target. The last approach using small molecule STAT3 inhibitors has been the most examined so Heterocyles and Carbazole. Heterocyles are an essential class of molecules, assuming a role in many aspect of our life. Indeed heterocyclic nucleus is a common feature of several biomolecule and bioactive compounds including agrochemical products and drugs. In this review we focused on two important class of heterocyclic compounds: carbazoles and NHCs (N-heterocyclic carbenes) and there implications in cancer inhibitions. Carbazoles, prevalent as structural motifs in various synthetic materials and naturally occurring alkaloids, as is known, have many applications especially as promising bioactive compounds due to their biological properties, known since 1965. Furthermore NHCs are a class of stable carbenes that over the last few years have entered the field as “new” ligands for bioactive coordination compounds. It has been demonstrated that metal NHC complexes can be used to develop highly efficient metal based drugs with possible applications in the treatment of cancer or infectious diseases.

Atrial Fibrillation Natriuretic Peptide Levels in Atrial Fibrillation A Prospective Hormonal and Doppler-Echocardiographic Study

RESULTS Patients with A-Fib compared with those in sinus rhythm had similar symptoms, comorbid conditions, cardioactive medications, pulmonary pressure, left atrial volume, and LV ejection fraction and filling characteristics but demonstrated higher N-ANP levels (2,613 6 1,681 vs. 1,654 6 1,323 pg/ml, p 5 0.007) even after adjustment for the underlying cardiac disease (p , 0.0001). Conversely, BNP levels were similar in both groups (165 6 163 vs. 160 6 269 pg/ml, p 5 0.9). In multivariate analysis, a higher N-ANP level was associated with A-Fib (p 5 0.0003), symptom class (p , 0.0001) and endothelin-1 level (p 5 0.032) independently of left atrial volume and LV ejection fraction. Conversely, BNP showed no independent association with and was most strongly associated with LV ejection fraction (p , 0.0001).

Content analysis of DBA and PhD dissertations in business

ABSTRACT The doctor of business administration (DBA) degree is widely considered as a professional doctorate or professional doctoral degree that is designed to prepare business practitioners. The doctor of philosophy (PhD) in business, by contrast, is thought to prepare research scholars and higher education faculty members. Prior research conducted by the authors comparing the curriculum of DBA and PhD programs, analyzing accreditation and regulation of the degree programs and examining the terminal degrees of business faculty, did not support the theoretical difference between the two degrees. This study consisted of an analysis of 147 DBA versus 151 PhD dissertations. The analysis indicated a significant group mean difference in the number of PhD versus DBA dissertations in institutions with an R1 classification by the Carnegie Commission on Higher Education. However, no significant correlations nor group mean differences were found in methodology choice, sample size, or research type (applied vs. basic), based on the degree type (DBA vs. PhD).
A NEW PERSPECTIVE for the INTERPRETATION of ULTRASONIC RESPONSES and its CONSEQUENCES in the DETERMINATION of „PROBABILITY of DETECTION“ CURVES

One of the most important aspects in the application of the „Damage Tolerant“ design approach to mechanical components is the probability to detect possible in-service defects. In the present paper, a novel approach, recently proposed by the author, to the interpretation of ultrasonic responses is presented. Such approach allows a new way of thinking for a more flexible and versatile procedure for the derivation of „probability of detection” curves. A high number of dedicated UT inspection experiments, carried out on artificial and natural fatigue cracks, are described in order to build up the procedure with the appropriate statistical parameters. Since the experiments typically needed to derive probability of detection curves with proper statistical reliability are expensive, the possibility to exchange part of the experiments with suitable numerical simulation is here considered.
The Employment and Wage Effects of Export VAT Rebates: Evidence from China

This paper studies the employment and wage effects of VAT rebates to exporters with comprehensive firm-product-level data of China. It is found that the adjustments in VAT rebates significantly and positively affect firm’s employment but have no statistically significant effect on firm’s wage. Moreover, this paper finds that the employment effect of VAT rebates is heterogeneous across firms. In particular, low-productivity firms are more sensitive to the adjustments of VAT rebates than high-productivity firms, suggesting that an increase of VAT rebates may cause mis-reallocation of resources.
Analysis of Electric Propulsion Capabilities in Establishment and Keeping of Formation Flying Nanosatellites

Nanosatellite clusters are one of the current and future trends in space technology. In order to maintain a satellite cluster, over a long period of time, the nanosatellites need to mitigate the alongtrack drift created by the initial orbit injection. In the mass range of 1-10 kg, CubeSats have strict constraints on allowed mass, volume, electrical power, and are equipped with only limited sensor and actuator capability. State of the art miniaturized electric propulsion (EP) systems are one option to realize the required orbit control capability. Due to the low thrust provided by an EP system, long orbit control maneuvers are required. Therefore, mission design is highly effected by long-term attitude and power constraints. Assuming a cyclic thrust controller, four methods were developed to allocate the satellite power and attitude resources for orbit control. Two time division methods are developed that allocate dedicated time slots for each of the satellite main tasks. Alternatively, two cosine methods are presented that utilize an error cone, around the required attitude, as a criterion for selecting when to operate the thruster. As a test case a typical deployment scenario was chosen with three 6U CubeSats. The CubeSats are equipped with a 100 N thruster with 1000 s specific impulse. Using a CubeSat power system model and a high fidelity orbit simulation, it was shown that all the resource allocation methods were successful in realizing a CubeSat formation flying mission. The fuel mass consumed was less than 2 g and the maneuver duration was less than 20 days.
