Neuro-behavioral pattern of sleep bruxism in wakefulness

Introduction: Sleep Bruxism (SB) is a non-functional rhythmic movement of the mandible with multifactorial aetiology and complex diagnose. It has been the subject of various studies over the past decades and it is considered a result of actions of the Central Nervous System modulated by Autonomous Nervous System. In this work, we test the hypothesis that SB subjects present a typical and defined neurobehavioral pattern that can be distinct from that of non-bruxers subjects and can be measured during wakefulness. Methods: Fifteen sleep bruxers (experimental-group EG) and fifteen non-bruxers (control-group CG) took part in the experiments. To verify the presence and severity of SB, clinical examinations, anamneses and questionnaires, including Visual Analogic Scale faces (VAS-f) and State-Trait Anxiety Inventory (STAI) were applied. To legitimate the diagnoses of SB, a disposable instrument (Bitestrip) to assess the masseter activity during sleep was employed. All subjects were submitted to a set of experiments for measuring various visual evoked responses during the presentation of visual stimuli (pleasant, unpleasant and neutral images). Events in Visual Evoked Potential (VEP) were used to compare the neural responses of both CG and EG. Results: VAS-f showed EG with higher perception of stress than CG (trait: p=0.05), and lower quality of life for (state: p=0.007). STAI I and II showed significant differences of anxiety between CG and EG (p=0.013 and p=0.004, respectively), being EG the highest. The EG Bitestrip scores confirmed that 100% of subjects were sleep bruxers. Significant differences were found between EG and CG for events associated with emotional (pleasant and unpleasant) images in the first 250 ms after stimulation. In general, EG subjects showed higher amplitude and shorter latency of VEP events. Conclusion: It is possible to distinguish between SB and non-bruxers subjects during wakefulness, based on differences in amplitude and latency of cortical event related potentials elicited by visual stimulation. SB subjects show greater amplitudes in specific events in frontal areas when non-pleasant images are shown. Latencies tend to be anticipated in SB compared to CG subjects.
Nedforia: A Tool for Automatic Named Entity Disambiguation

In 2011, IBM showed for the rst time that a computer could surpass human question answering capabilities. is feat was accomplished by designing a system that could play the American game show Jeopardy! against human contestants. In this huge undertaking, one of the problems IBMhad to solve was named entity disambiguation. Named entity disambiguation is about the automatic identi cation of a real-world reference to a given string. IBM’s work was limited to English and very little research is dedicated to named entity disambiguation for Swedish. In this thesis, I report the design and implementation of Nedforia, a named entity disambiguation tool for Swedish. Nedforia provides a full pipeline beginning with a dump of Wikipedia and ending with a disambiguator. Nedforia’s core contribution consists of modules to parse wiki markup reliably, extract relevant pieces of information from Wikipedia, and manage large amounts of information. To evaluate the nal disambiguation tool, I collected a test set created from 10 news articles where I hand-annotated and disambiguated the named entities. On this set, Nedforia could reach an F1-score of 66.49% using a Swedish Wikipedia dump from 2013-02-25. In addition to Swedish, Neforia could easily be extended to support and manage multiple languages.
Performance behavior evaluation of Internet congestion control policing mechanisms

Performance behavior is an important issue in the design and implementation of an efficient Internet congestion control policing mechanism. The effectiveness of such a mechanism can be measured by packet loss probability, bandwidth allocation, packet delay, throughput or other quality of service measures. In this paper, we carry out a comprehensive study to investigate the performance behavior of four selected policing mechanisms for the Internet namely: token bucket (TB), jumping window (JW), triggered jumping window (TJW) and exponentially weighted moving average (EWMA). Three types of bursty sources modeled as On/Off, Poisson and batched Poisson processes are utilized. Three criteria are used to evaluate the performance behavior of the selected policing mechanisms. These are the average packet delay, the average packet loss probability and the average number of lost credits. Computer simulations were used to arrive at various conclusions regarding the dependence of performance on source traffic characteristics and policing mechanism parameters. Furthermore, a comparison of the performance behavior of the selected policing mechanisms was carried for different input traffic characteristics.
Simulation Analysis of Wireless Power Transmission System for Biomedical Applications

In recent years, more and more implantable medical devices have been used in the medical field. Some of these devices, such as brain pacemakers, require long-term power support. The WPT(wireless power transmission) technology which is more convenient and economical than replacing the battery by surgery, has become the first choice of many patients. In this paper, we design a WPT system that can be used in implantable medical devices, simulate the transmission efficiency of the system in the air and in the head model, and simulate the SAR value when the system working in the head model. The results show that when implantation depth of the secondary coil is 3 mm, the efficiency of the system can reach 45%, and the maximum average SAR value is 2.19 W / kg, slightly higher than the standard of IEEE.
Practice for Second Language Learning: Don't Throw out the Baby with the Bathwater.

After presenting some of the main arguments against certain narrow concepts of second language practice, this article argues that a broader concept of practice, still focused on form or even forms, but with due attention to form-meaning links and with appropriate sequencing of activities to ensure declarative knowledge first, followed by its proceduralization and (at least partial) automatization, is as relevant as ever. A brief overview is given of the range of activities that fall within this concept, and recommendations are made for adaptation to students’ individual and group differences.
Is there life beyond language testing? An introduction to alternative language assessment.

This paper aims to be an introduction to the so-called ‘movement of alternative assessment’ (Alderson and Banerjee, 2001) that has recently made its appearance within the field of language testing and assessment. The paper attempts to familiarise readers interested in the area with the fundamental principles, much of the associated terminology and methods. It also raises a number of issues in the hope that they will serve as a springboard for further discussion, research and experimentation in the field.
Coding strategies for OFDM with antenna diversity high-bit-rate mobile data applications

In this paper, we investigate coding strategies for an OFDM system with antenna diversity. To maximize coding efficiency, interleaving in the two-dimensional frequency-time domain is studied. In particular, transmission over multiple antennas, which achieves an interleaving effect by randomizing the fading over the subchannels, is employed. Based on the best interleaving method, we consider convolutional coding and compare its performance with that of Reed-Solomon coding. Simulation results indicate that a 1/2-rate convolutional code requires a constraint length of at least 6, with soft decisions, to achieve better performance than a 1/2-rate (40,20) Reed-Solomon code with 6-bit symbols and a combination of erasure and error correction. In addition, a concatenated coding scheme, combining convolutional and Reed-Solomon coding, is presented and is shown to achieve improved performance with lower complexity.
Competency matrix assessment in an integrated, first-year curriculum in science, engineering, and mathematics

The Integrated, First-Year Curriculum in Science, Engineering, and Mathematics (IFYCSEM) at Rose-Hulman Institute of Technology integrates topics in calculus, mechanics, statics, electricity and magnetism, computer science, general chemistry engineering design, and engineering graphics into a three course, 12-credit-per-quarter sequence. In 1995-96, faculty teaching IFYCSEM decided to move toward a competency matrix assessment approach. Using a competency matrix, faculty establish a 2D grid. Along the vertical dimension of the grid, faculty list the topics and techniques with which they believe students should become facile. Along the horizontal dimension are the levels of learning according to the taxonomy: knowledge, comprehension, application, analysis, synthesis, evaluation. For each topic in the vertical dimension, faculty establish the desired level of learning associated with a grade: A, B or C. For each quarter in 1995-96, the resulting matrix contained about 500-600 elements or blocks. When a student has demonstrated a level of learning for a particular topic, the student marks the block as earned and enters in the competency matrix a reference to his/her portfolio showing where the supporting document may be found. Students maintain their own portfolios and competency matrices and at the end of each quarter students submit their competency matrix along with a portfolio as documentation. Faculty assign a grade based on the competency matrix. We present descriptions of the rationale and process and discuss advantages and disadvantages, including feedback from both faculty and students.
Technology Acceptance in Education: Research and issues

The purpose of this study was to: a) investigate student teachers’ and experienced classroom teachers’ computer usage beliefs, intentions, and self-reported computer usage in the classroom using a mixed methodology approach (i.e., quantitative and qualitative), and b) examine the efficacy of the technology acceptance model (TAM) and the decomposed theory of planned behavior (DTPB) for predicting computer usage intentions. This study consisted of a sample of 160 student teachers and 158 experienced teachers from classes within a large urban university. All participants completed a Computer Usage Intention Survey. This survey was developed using a theoretical framework of the technology acceptance model (TAM) (Davis, 1989, 1993; Davis, Bagozzi, & Warshaw, 1989). The survey determined participants’ beliefs, future intentions usage (for the coming 6 months) and self-reported usage (for the past three months) of integrating computer applications (e.g. Word Processing, Spreadsheets, Database, Multimedia, Internet, Games, Drill and Practice, Simulations, Tutorials, Problem Solving, and educational subject-specific software) into subjectspecific lessons. After completion of the Computer Usage Intentions Survey, a purposeful sample of the study’s participants was selected for semi-structured interviews. This sample consisted of a total of 19 participants, 10 student teachers and 9 experienced classroom teachers. The interview questionnaire was developed using a theoretical framework of the decomposed theory of planned behavior (Taylor & Todd, 1995). Although the TAM was a good predictor of intentions, the DTPB emerged as the most important model for predicting teachers’ intentions. Similarities as well as significant differences were found between student teachers’ and experienced teachers’ computer usage.
Unheard Complaints: Integrating Captioning Into Business and Professional Communication Presentations

This article explores pedagogical frameworks closely associated with d/Deaf and hard-of-hearing persons from the perspective of a disabled instructor to increase student awareness of the needs of diverse audiences they will encounter in the workforce. The author argues that students and instructors can use captioning theory to strategize one of the harder business communication genres, the presentation, for d/Deaf audiences to make communication more accessible. By raising critical awareness of the limits of technology, current trends in pedagogy, and disability, this article seeks to further the conversation about providing accessibility for disabled users in the classroom.
Force Tracking in Impedance Control

This article presents two simple on-line schemes for force tracking within the impedance-control framework. The force- tracking capability of impedance control is particularly important for providing robustness in the presence of large uncertainties or variations in environmental parameters. The two proposed schemes generate the reference position trajec tory required to produce a desired contact force despite lack of knowledge of the environmental stiffness and location. The first scheme uses direct adaptive control to generate the refer ence position on-line as a function of the force-tracking error. Alternatively, the second scheme utilizes an indirect adaptive strategy in which the environmental parameters are estimated on-line, and the required reference position is computed based on these estimates. In both schemes, adaptation allows au tomatic gain adjustment to provide a uniform performance despite variations in the environmental parameters. Simula tion studies are presented for a 7-DOF Robotics Research arm using full arm dynamics, demonstrating that the adaptive schemes are able to compensate for uncertainties in both the environmental stiffness and location. The simulation studies also highlight the limitations of pure impedance control without the force-tracking capability for robust execution of realistic contact tasks. Experimental results are also presented for the Robotics Research arm to demonstrate that the end effector applies the desired contact force while exhibiting the specified impedance dynamics.

This research was based on the phenomenon that the learning that has been done was not optimal to raise the understanding in studying the microbiology subject, it is indicated by the numbers of the students who have not been able to reach the expected learning result. It showed that the learning process of Microbiology subject needs to be developed with different approach, that is by using the application of mobile learning based HTML5 . The aim of this research is to figure out: the use of mobile learning based HTML5 in improving students understanding in Microbiology course. The result of this research can be concluded that the average of pretest and posttest score in experiment class was 54,77 and 79,96 with normalized gain value is 0.56 (medium category). While in the control class the average pretest and posttest score was 39.96 and 61.19 with normalized gain value is 0.35 (medium category). There was different average score on posttest and increase understanding of students who used mobile learning based HTML5 application on real higher than the students who studied in conventional learning method.
A Case-Control Study of Effect of Opium Addiction on Myocardial Infarction

Ischemic Heart Disease (IHD) and Myocardial Infarction (MI) are one of the most important disease which cause mortality and morbidity. Opioid peptides and exogenous opioid such as morphine are known to exert an important cardiovascular effect. To study effect of opium addiction to incidence of MI. A Case-Control study was designed in Kerman university. 150 patients with MI was admitted to CCU and 150 matched patients admitted in surgical wards evaluate from cardiovascular risk factor and opium addiction. Analysis of data suggested no difference between two groups (P>0.05). But smoking OR = 2.45, hypertension OR = 2.65, Diabetes mellitus OR = 1.82 and Hypercholesterolemia OR = 3.16 were a risk factor for MI. Effect of opium in IHD has controversial. But recent of study defined that opioid peptides have a cardioprotective effect. Many exact and longitudinal studies should design for this purpose.
Educational Data Mining and Analysis of Students’ Academic Performance Using WEKA

In this competitive scenario of the educational system, the higher education institutes use data mining tools and techniques for academic improvement of the student performance and to prevent drop out. The authors collected data from three colleges of Assam, India. The data consists of socio-economic, demographic as well as academic information of three hundred students with twenty-four attributes. Four classification methods, the J48, PART, Random Forest and Bayes Network Classifiers were used. The data mining tool used was WEKA. The high influential attributes were selected using the tool. The internal assessment attribute in the continuous evaluation process makes the highest impact in the final semester results of the students in our dataset. The results showed that random forest outperforms the other classifiers based on accuracy and classifier errors. Apriori algorithm was also used to find the association rule mining among all the attributes and the best rules were also displayed.
th Information Systems International Conference 2017 , ISICO 2017 , 6-8 November 2017 , Bali , Indonesia User Satisfaction and Intention to Use Peer-to-Peer Online Transportation : A Replication Study

Sharing economy or collaborative economy (e.g. renting and lending) has been identified in previous studies to better understanding the behavioral context such as satisfaction and future intention for hospitality accommodation. However, the findings are lack of generalization in other industry context. Therefore, as the phenomenon of peer-to-peer (P2P) online transportation in Indonesia, this article replicates the previous study by Tussyadiah (2016) to test consumers’ satisfaction and future intention in different industry context for generalization purposes. Using Structural Equational Modelling approach, the results among 115 respondents conclude that enjoyment and economic benefit are the determinations of satisfaction while satisfaction itself mediates those variables toward future intention. This study concludes that some of the findings about determinant factors of customer satisfaction future intention on P2P accommodation context can be generalized for other industrial context such as P2P online transportation context even though there are some differences of findings especially in the antecedents of future intention. © 2018 The Authors.

Natural Scene Statistics at Monkey's Center of Gaze

Overt visual attention is studied both in humans and monkeys. Yet, for interpreting and generalizing results of studies on either species there is need for more comparative studies on monkeys. Here, in close analogy to a previous study of human overt attention (Reinagel and Zador, 1999), we investigated gaze movements of monkeys viewing natural visual stimuli. To capture the attention of the animals in a free viewing task we deliberately included a large proportion of pictures of animals and humans. The contribution of stimulus features like luminance contrast and spatial correlation of luminance to guidance of gaze movements were investigated. We found a large and highly significant increase of luminance contrast at fixation points. In comparison to previously published human data, this effect was more than 20% higher in monkeys. This difference is also expressed in the reduced spatial correlation at fixation points selected by monkeys as compared to humans. However, a saliency map based solely on luminance contrast cannot explain the observed data. This indicates that more complex bottom-up cues like texture contrast and top-down cues have a strong influence on overt attention in monkeys. In summary, compared to humans we found that low-level features have a stronger effect on guiding overt attention in monkeys.
Temporal attributes of the bidirectional reflectance for three boreal forest canopies

Multidirectional ground-based optical measurements were acquired along tramways above and beneath three important boreal forest canopies to characterize the complete radiative transfer of visible through shortwave infrared wavelengths. The three forest canopy types exhibited bidirectional reflectance features that were distinctively different from each other not only in their magnitudes of reflectance in a given spectral wavelength band and at forward and backscatter angles but also in their diurnal and seasonal changes. The above-canopy data analyses indicate that each of these forest types must be considered as having unique bidirectional reflectance distribution functions and should be modeled individually for both direct (e.g. albedo) and indirect (e.g. biophysical parameter assessments) applications in the quantitative remote sensing of the boreal forest biome.
ERS-1 scatterometer off-line products: calibration/validation results and case studies

Calibration and validation tests performed at IFREMER has shown the need to reprocess the ERS-1 scatterometer archive. The new data-set is carefully examined. The data accuracy is determined by comparison with the NOAA buoy data, showing that good accuracy is achieved (1.2 m/s and 15/spl deg/ standard deviations). Nevertheless the scatterometer wind data are biased low at very high wind speed (>20 m/s) and also exhibit a bias depending on the atmospheric boundary layer stability. The resolution and the very low level of noise in the scatterometer data allows the measurement of small scale features in the wind field that are not seen by the meteorological numerical models. Two cases of tropical cyclones are presented. <<ETX>>
Big-Men and Small Chiefs: The Creation of Bronze Age Societies

Abstract This paper investigates to what extent the significant material changes observable at the end of the Neolithic reflect transformations of the underlying social dynamics. Answering this question will help us to understand the formation of Bronze Age societies. The analysis concerns southern Scandinavia with a certain focus on Denmark. The assumption is that the creation of Bronze Age societies must be understood as a long formative process that partly originated in the culturally-heterogeneous Middle Neolithic. Four aspects seem to have been essential to this process: the rise of the warrior figure, the reintroduction of metal, increased agricultural production, and the establishment of one of the characteristic features of the Bronze Age, the chieftain hall. These aspects do not appear simultaneously but are introduced stepby- step starting out in the late Middle Neolithic and early Late Neolithic to fully develop around 2000 BC. Consequently, this paper argues that the final Late Neolithic (LN II, c. 1950-1700 BC) was de facto part of the Earliest Bronze Age.
