Model structure selection using an integrated forward orthogonal search algorithm assisted by squared correlation and mutual information

Model structure selection plays a key role in non-linear system identification. The first step in non-linear system identification is to determine which model terms should be included in the model. Once significant model terms have been determined, a model selection criterion can then be applied to select a suitable model subset. The well known Orthogonal Least Squares (OLS) type algorithms are one of the most efficient and commonly used techniques for model structure selection. However, it has been observed that the OLS type algorithms may occasionally select incorrect model terms or yield a redundant model subset in the presence of particular noise structures or input signals. A very efficient Integrated Forward Orthogonal Search (IFOS) algorithm, which is assisted by the squared correlation and mutual information, and which incorporates a Generalised Cross-Validation (GCV) criterion and hypothesis tests, is introduced to overcome these limitations in model structure selection.
Postural responses applied in a control model in cochlear implant users with pre-lingual hearing loss

Abstract Conclusions The assessment of postural responses (PR) based in a feedback control system model shows selective gains in different bands of frequencies adaptable with child development. Objective PR characterization of pre-lingual cochlear implant users (CIU) in different sensory conditions. Methods Total energy consumption of the body’s center of pressure signal (ECCOP) and its distribution in three bands of frequencies: band 1 (0–0.1 Hz), band 2 (0.1–0.7 Hz), and band 3 (0.7–20 Hz) was measured in a sample of 18 CIU (8–16 years old) and in a control group (CG) (8–15 years old). They were assessed in a standing position on a force platform in two sensory conditions: 1 = Eyes open. 2 = Eyes closed and standing on foam. Results In condition 1, total ECCOP of PR and its proportion of energy consumption in the three bands of frequencies were similar between CIU and CG (p > 0.05). In condition 2, CIU have significantly higher ECCOP, mainly in high frequencies (bands 2 and 3) (p < 0.05). ECCOP values decreased with age also, mainly in bands 2 and 3. This behavior is interpreted in the control system model proposed as an adaptation process related with child development.
Neural network augmented backstepping control for an induction machine

A new control approach is proposed to address the tracking problem of an induction machine based on a modified Field-Oriented Control (FOC) method. In this approach, one relies first on a partially known model to the system to be controlled using a backstepping control strategy. The obtained controller is then augmented by an Adaptive Neural Network (NN) that serves as an approximator for the neglected dynamics and modelling errors. The proposed approach is systematic, and exploits the known non-linear dynamics to derive the stepwise virtual stabilising control laws. At the final step, an augmented Lyapunov function is introduced to derive the adaptation laws of the network weights. The effectiveness of the proposed controller is demonstrated through computer simulation.
Psychophysiological determinants of repeated ventilator weaning failure: an explanatory model.

BACKGROUND The adverse effects of a failed ventilator weaning trial on the subsequent weaning attempts are not well understood. OBJECTIVES To examine physiological and psychological factors that may be predictive of risk for repeated weaning failures and prolonged mechanical ventilation. METHODS A prospective predictive study of 102 subjects, age 34 to 91 years, whose first ventilator weaning trial was unsuccessful but who were physiologically ready for another weaning attempt. Subjects were recruited from intensive care units and a respiratory care center of a tertiary medical center. Validated self-report scales and a Bicore monitoring system were used to measure ventilator patients' psychophysiological performance during the second weaning trial. Structural equation modeling was used to analyze the data and test the model. RESULTS Significant causal pathways were found between fear and anxiety (r = 0.77; P < .001), anxiety and respiratory function (r = 0.24; P < .05), and respiratory function and weaning outcomes (r = 0.42; P < .001). The overall model predicted that both physiological and psychological factors were important in determining repeated failure of ventilator weaning, and the data were in support of the model (χ(2) = 29.49, P > . 05). CONCLUSIONS Patients whose first ventilator weaning trial is unsuccessful may be markedly fearful. Left unaddressed, these fears cause high anxiety levels that significantly compromise respiratory function and contribute to subsequent weaning failures. Thus begins a vicious cycle of repeated failure of ventilator weaning and prolonged mechanical ventilation.
Attendance and reattendance for breast cancer screening: A prospective 3‐year test of the Theory of Planned Behaviour

Objective. To test the ability of the Theory of Planned Behaviour (TPB) to predict attendance for breast cancer screening and reattendance 3 years later, using data from a prospective longitudinal study. Method. A total of 1215 women who had never had breast screening completed a postal questionnaire sent to them shortly before they were to receive their first invitation for X-ray mammography in the UK's National Health Service Breast Screening Programme. The questionnaire included items to tap attitude, subjective norm, perceived behavioural control and intention to attend. Attendance and then reattendance 3 years later were monitored from screening clinic records. Results. Two main results are reported. (1) Intention and first-time attendance were predicted successfully from the TPB, and attendance was the single predictor of reattendance 3 years later. (2) The TPB was able to distinguish between intenders who attended and those who did nor. Conclusion. The implications of the results are considered both for theory and for policy and practice. Particular attention is paid to the possibility of designing interventions to increase attendance and reattendance.
Optimisation and simulation on dynamic balance distribution algorithm for network traffic

According to the features of multipath routing of MPLS and the shortcomings of existing load balancing algorithms, we build a distribution model and put forward a dynamic multi-objective and multipath load distribution mechanism to optimise network for the attributes of Qos including the load factor and the minimum hop. A better candidate path set is selected to replace a single best candidate path to transmit data by means of constructing probability coefficient and load proportion coefficient as routing standard. To get a more reasonable allocation of the network-source, the dynamic balance distribution algorithm is used to distribute the traffic. The simulations by MATLAB show that the improved algorithm can avoid network congestion effectively, and decrease the total delay obviously.
Guidelines for carcinogen risk assessment

Pressure-sensitive master sheets are produced by printing ink-releasing images onto a master sheet by silk screen techniques using a semi-solid printable ink composition comprising a wax and/or resin binder material, an incompatible oleaginous material, colorant and a volatile vehicle. The solidifed printed images comprise a porous, spongy network of the binder material containing within the pores thereof the oleaginous material and colorant as a pressure-exudable ink. The printed master is suitable for the production of several copies in a dry pressure-copying process.
Hemodynamic Evaluation of Mitral Stenosis Using Stress Echocardiography

Objectives- The aim of this study was to evaluate the relation of symptoms to valve stenosis. The hemodynamic data were evaluated at rest and after exercise using exercise stress echocardiography. Methods- We prospectively studied hemodynamic data in 15 consecutive patients with moderate mitral stenosis (MS) who were in NYHA function class two or higher. Treadmill exercise stress echocardiography (Bruce protocol) was done (GE Vingmed CFM 800). Mitral valve area (by planimetry and PHT method), mean TMVG, peak TMVG, and PAP were measured in all the patients at rest and within 90 seconds after the termination of exercise. Results- In 66.7% of patients with moderate mitral stenosis, the stenosis was hemodynamically significant regarding the increase in mean TMVG (2 times in comparison with rest, or more than 15mmHg) and PAP after exercise. Conclusions- Our results suggest that in patients with moderate mitral stenosis, hemodynamic response to exercise has better correlation with the degree of valve stenosis severity and the occurrence of symptoms. In these patients, exercise stress Doppler echocardiography is a noninvasive and reliable method to assess the mitral flow characteristics (Iranian Heart Journal 2007; 8 (2): 35-38).
Predicting discharge to a long-term acute care hospital after admission to an intensive care unit.

BACKGROUND Long-term acute care hospitals are an option for patients in intensive care units who require prolonged care after an acute illness. Predicting use of these facilities may help hospitals improve resource management, expenditures, and quality of care delivered in intensive care. OBJECTIVE To develop a predictive tool for early identification of intensive care patients with increased probability of transfer to such a hospital. METHODS Data on 1967 adults admitted to intensive care at a tertiary care hospital between January 2009 and June 2009 were retrospectively reviewed. The prediction model was developed by using multiple ordinal logistic regression. The model was internally validated via the bootstrapping technique and externally validated with a control cohort of 950 intensive care patients. RESULTS Among the study group, 146 patients (7.4%) were discharged to long-term acute care hospitals and 1582 (80.4%) to home or other care facilities; 239 (12.2%) died in the intensive care unit. The final prediction algorithm showed good accuracy (bias-corrected concordance index, 0.825; 95% CI, 0.803-0.845), excellent calibration, and external validation (concordance index, 0.789; 95% CI, 0.754-0.824). Hypoalbuminemia was the greatest potential driver of increased likelihood of discharge to a long-term acute care hospital. Other important predictors were intensive care unit category, older age, extended hospital stay before admission to intensive care, severe pressure ulcers, admission source, and dependency on mechanical ventilation. CONCLUSIONS This new predictive tool can help estimate on the first day of admission to intensive care the likelihood of a patient's discharge to a long-term acute care hospital.
Swift heavy ion irradiation induced modification of current-voltage characteristics of heavily doped Au/n-GaAs Schottky diode

The modifications in current-voltage (I-V) characteristics of a Au/n-GaAs Schottky diode induced by 180 MeV /sup 107/Ag/sup 14+/ ion irradiation at a low temperature (80 K) have been studied. The irradiation fluence was varied from 5/spl times/10/sup 10/ cm/sup -2/ to 1/spl times/10/sup 13/ cm/sup -2/. The I-V characterization of the pristine and irradiated diodes was performed at 300 K and 80 K. The n-GaAs wafer used for fabricating the Schottky diode was heavily doped (n=1/spl times/10/sup 18/ cm/sup -3/) and hence the current transport across the metal-semiconductor junction was described by thermionic-field emission process. The variation in diode parameters like tunneling parameter E/sub 0/, ideality factor n and saturation current (I/sub s/) has been studied as a function of irradiation fluence.
Direct fuzzy adaptive control based on sliding surface for a class of SISO non-linear systems

In this work we are interested in direct fuzzy adaptive control. The continuous SISO non-linear system is presented by the Takgi-Sugeno type fuzzy state model. The strategy of reference model direct adaptive control theory is presented then the adaptive fuzzy adjustment algorithm is presented. The control law includes two terms. The first is responsible to stabilise the plant is computed based on PDC method. The second constitutes the feed forward gain. All the parameters of the controller are adjusted online. The adjustment algorithm of the controller parameters exploits the sliding surface to profit of robustness of sliding mode control. The stability analysis of the closed-loop system has been proven using the Lyapunov approach. The single synchronous generator coupled to the infinite-bus power system is used to check the performances of the proposed control scheme.
Affective and Anxiety Disorders and their Relationship with Chronic Physical Conditions in Australia: Findings of the 2007 National Survey of Mental Health and Wellbeing

Objective: The aim of this study was to report nationally representative data on the prevalence and patterns of 12 month comorbidity of chronic physical conditions (diabetes, asthma, coronary heart disease, stroke, cancer, arthritis) and DSM-IV affective and anxiety disorders in Australian adults. Method: The 2007 National Survey of Mental Health and Wellbeing (NSMHWB) was a nationally representative household survey of 8841 Australian adults (16–85 years) assessing symptoms of ICD-10 mental disorders and the presence of chronic physical conditions. Results: Prevalence of at least one National Health Priority Area chronic physical condition was 32.2% (95%CI = 30.9%–33.5%). Among those with chronic physical conditions 21.9% had an affective or anxiety disorder. Affective and anxiety disorders were more common among people with physical conditions than among people without chronic physical conditions (affective OR 1.5; anxiety OR 1.8). Of those with a 12 month affective or anxiety disorder, 45.6% had a chronic physical condition. Physical disorders were more common in those with an affective or anxiety disorder than among people without an affective or anxiety disorder (affective OR 1.6; anxiety OR 2.0). Disability was high in those with an anxiety disorder, an affective disorder and a physical condition and 43.4% were classified as high service users. Conclusions: Comorbidity between chronic physical conditions and affective and anxiety disorders is widespread and is associated with high levels of disability and service use.
Modelling for a joint production-distribution problem and its hybrid algorithm design

With market globalisation, ignoring the dependencies of the functions of a supply chain can have costly consequences. As a result, companies are moving from decoupled decision making processes toward more collaborative design and control of all of their components. Constructing collaborative supply chain structures is crucial in gaining a sustainable competitive advantage. Therefore, in this paper, a three stages joint production-distribution problem in a supply chain consisting of a single manufacturer and multiple retailers is considered. The manufacturer produces multiple items on a single facility under a common horizon and delivers the finished products to its retailers. A single model is proposed to integrate production lot sizing, scheduling and finished goods distribution. The model is designed to find the production lot sizes, the delivery quantities and the production sequence of multiple items to minimise the sum of setup cost, holding cost, stock-out cost and distribution cost. A hybrid algori.
Extending the tradition of giving thanks recognizing the health benefits of gratitude.

This time of year resonates with messages of gratitude for the many blessings we have in our lives. Family, friends, neighbors, fond acquaintances, and, at times, complete strangers extend their appreciation for expressions of kindness, thoughtfulness, love, or simple courtesy toward one another. Although we may collectively take pride in having institutionalized, extolled, and enjoyed our national expression of gratitude every November since 1863, an accumulating body of evidence suggests we should consider extending the frequency of our individual celebrations of gratitude from once a year to once a day. Can you recall the last time you looked someone in the eye and related how important they were in your life, how precious your time with them was, or how much their support enabled you to endure a difficult circumstance? Do you remember how sharing that message made you and the object of your gratitude feel? Studies now suggest that reflecting on the benefits we derive from others and conveying our thanks in such simple and straightforward messages evokes an array of psychological, social, and physical gains that promote our psychosocial and physiologic health. Perhaps it is time to take a closer look at gratitude and the glow of good it offers. The Nature of Gratitude The word gratitude originates from the Latin word gratus, meaning “thankfulness, appreciation of kindness. ” Gratitude has been categorized and conceptualized as an attitude, moral virtue, emotion, personality trait, feeling, motive and coping device. Some early discussion of the nature of gratitude classified it as one of the empathetic emotions. A theme prevalent throughout descriptions of this emotion involves acknowledgment with appreciation of an altruistic gift. The specific nature of that gift or gain may be either tangible or intangible and can be the gesture or intent that the kindness represents rather than the actual item or benefit conveyed. Fitzgerald distinguished 3 components of gratitude that define and encompass the process for its expression: • A warm sense of appreciation for something or somebody • A sense of goodwill toward that thing or person • A resulting disposition to act positively due to that appreciation
Leucocyte depleting filters and cardiothoracic surgery

Leucocyte filtration technology is now beginning to be used in cardiothoracic surgery. The leucocyte depletion of banked homologous blood has been shown to reduce its immunosuppressive effects, along with a range of other benefits. Use of such a blood product appears to be an attractive option during cardiopulmonary bypass (CPB) as this procedure is recognized as causing immune disturbance and long-term immunosuppression. White-cell removal filters also appear to have a novel application in the reduction of neutrophil-mediated damage associated with CPB procedures. A strong database from animal work has been recently supplemented by human data that shows clinical benefits from autologous white-cell removal by filtration.
Role of common website features on providing a secure news website: an empirical approach

News websites provide various kinds of information and have a great contribution in creating knowledge to community citizens. Providing security has a great impact on the usability of these websites and encourages users to trust and share their personal information to take advantages of various facilities on the news website. The main contribution of this paper is to examine if website features affect designing a secure news website. The features have been classified by a deep and complete review of the most applicable features in news websites through the study of the top 50 international news websites. Validating the classification was the next step, which was held by identifying experts’ opinions about the most pertinent features of news websites that affect the security of the news websites. The aim of this paper is to find out the correlation of each identified feature with each security service. The result would be beneficial for news website’s administrators to design these websites effectively and securely in order to satisfy their users by suitable response to their requirements.
The periodontal disease status of the historical population of Assos

The science of anthropology obtains data on health, disease and death from ancient populations. Research on the skeletal remains of human teeth and surrounding tissues provides useful information on the evolutionary perspective of dental and periodontal diseases. The aim of this study was to determine the prevalence and severity of periodontal diseases in the skeletal remains of 33 Assos inhabitants of the 4th century BC. Three age groups were constituted for the studied population. Periodontal disease status was determined based on the textural and architectural variations of the interdental septum and the extent of bone loss. It was found that the prevalence of periodontal diseases increased with age. The severity of periodontal bone loss also increased with age and the mean alveolar bone loss between age groups was statistically significant (P = 0.004). This analysis of the dental health of ancient populations provides insights into the aetiology, patterns and distribution of periodontitis, which has a very complex disease pathogenesis.

Wireless implementation of a mobile learning environment based on students' expectations

In this paper, we describe the educational opportunities of teaching in a wireless classroom using notebooks and Personal Digital Assistants (PDAs). Specific mobile learning applications in wireless classrooms are developed for students and teachers, which is accessible on a Pocket PC and notebook computer. We have conducted a survey among university students and lecturers on the weaknesses faced in a conventional classroom and asked their opinion on what type of mobile learning applications they would intend to use in a classroom to help them learn and teach effectively. From the survey we provide a variety of tools such as mobile learning courseware system, which can be accessed on a Pocket PC, classroom group discussion, audio chat facility using Session Initiation Protocol and online assessments. Real-time chat is proposed to allow students and lecturers to communicate with each other during class. We also look into the didactic aspects of mobile learning and the usability issues in accessing information on mobile devices.
Reducing Risks Associated With Negative‐Pressure Wound Therapy: Strategies for Clinical Practice

&NA; Negative‐pressure wound therapy represents a relatively new strategy for wound management. Significant, life‐threatening complications (bleeding, infection, and retained dressing material) have been associated with negative‐pressure wound therapy. As a result, the Food and Drug Administration published several warnings to negative‐pressure wound therapy users and recommended that clinicians ordering, managing, and/or monitoring negative‐pressure wound therapy be aware of the potential complications and be prepared to take prompt action to reduce patients’ risk for harm. This article reviews and organizes published consensus, expert opinion, research, and manufacturer guidelines about patient safety during negative‐pressure wound therapy relevant to nurses practicing in acute and critical care settings, including in advanced practice roles.
