Ieee Comsoc Mmtc E-letter Multimedia Communications Technical Committee Ieee Communications Society E-letter Energy Efficiency and Spectrum Efficiency Co-design: from Noma to Network Noma21 Message from Mmtc Chair Emerging Topics: Special Issue on 5g Mobile Communications Technologies and Services

Dear MMTC colleagues: It is really a great honor for me to serve as the Asia vice-chair for this vital ComSoc Committee during the period 2014-2016! As part of my duties, I have contributed to the initial setting of the Interest Groups (IGs) and I am starting to work on the promotion of Special Issues (SIs)/symposiums/workshops with top journals/conferences. Actually, these two activities interact with each other, and the core challenge is to form attractive, active, and enthusiastic IGs. As a result, I really believe that these IGs represent the core of our networking and scientific activities and I warmly invite all of you to select one or more IG(s) to get involved by contacting the chair(s) so as to take part as key member. The activities of the IGs include, among others, the editing of special issues in major journals, the organization of workshops, sessions and conferences with the involvement of the MMTC, the setting of invited talks through conference calls that can be of interest for our community and the rest of the ComSoc members. While these are the major activities, some others can be carried out following the specific IG topics, such as the contribution to standardization activities. Essentially, these two activities will not success without strong support from our IG leaders and contributing members. At first, I will be working with all the IG Chairs to first identify a list of potential journals and conferences that are relevant to each IG. This list will be shared with all the members who have the interest to propose potential topics for a chosen venue. Then, we will socialize the topics with EiC(s) and Chair(s) to develop the full proposal on SI or symposium or workshop. It is our hope to achieve the largest efficiency via our collaborative efforts, ideally each IG can at least organize one SI or symposium or workshop per year. We also encourage multiple IGs to collaboratively propose topics that are relevant. In addition, we also hope IGs can take more constructive roles in our TC activities, for example, advertising the IG members to submit their papers to the multimedia symposium in ICC/Globecom. I would like to thank all the IG chairs and co-chairs for the work they have already done and will be doing for the success of MMTC and hope that any of you will find the proper IG of interest to get …
Decoupling of Standard Implementation from Certification: Does Quality of ISO 14001 Implementation Affect Facilities’ Environmental Performance?

The literature on certifiable management standards has not paid sufficient attention to implementation of standard requirements in certified firms. Firms that obtain standard certification to achieve the legitimacy benefits of certification may not implement standard requirements sufficiently to realize the standard’s intended performance outcomes. We argue that such decoupling of implementation from certification threatens the effectiveness of certifiable standards as governance mechanisms for firms’ environmental conduct because standard certification may not accurately signal firms’ superior environmental performance to external stakeholders. Empirical findings based on the ISO 14001 standard at the facility level support this view: Quality of standard implementation affects facilities’ environmental performance, and environmental performance of certified and non-certified facilities does not differ significantly for the overall sample and lowquality implementers, while high-quality implementers have better environmental performance than their non-certified counterparts. We provide recommendations for increasing the effectiveness of governance systems for firm conduct based on certifiable standards.
An XFEM method for modeling geometrically elaborate crack propagation in brittle materials

We present a method for simulating quasistatic crack propagation in 2-D which combines the extended finite element method (XFEM) with a general algorithm for cutting triangulated domains, and introduce a simple yet general and flexible quadrature rule based on the same geometric algorithm. The combination of these methods gives several advantages. First, the cutting algorithm provides a flexible and systematic way of determining material connectivity, which is required by the XFEM enrichment functions. Also, our integration scheme is straightfoward to implement and accurate, without requiring a triangulation that incorporates the new crack edges or the addition of new degrees of freedom to the system. The use of this cutting algorithm and integration rule allows for geometrically complicated domains and complex crack patterns. Copyright c © 2009 John Wiley & Sons, Ltd.
Ultrahigh electrical conductivity in solution-sheared polymeric transparent films.

UNLABELLED
With consumer electronics transitioning toward flexible products, there is a growing need for high-performance, mechanically robust, and inexpensive transparent conductors (TCs) for optoelectronic device integration. Herein, we report the scalable fabrication of highly conductive poly(3,4-ethylenedioxythiophene):poly(styrenesulfonate) (


PEDOT
PSS) thin films via solution shearing. Specific control over deposition conditions allows for tunable phase separation and preferential PEDOT backbone alignment, resulting in record-high electrical conductivities of 4,600 ± 100 S/cm while maintaining high optical transparency. High-performance solution-sheared TC PEDOT:PSS films were used as patterned electrodes in capacitive touch sensors and organic photovoltaics to demonstrate practical viability in optoelectronic applications.
Ultrasensitive non-enzymatic glucose sensor based on three-dimensional network of ZnO-CuO hierarchical nanocomposites by electrospinning

Three-dimensional (3D) porous ZnO-CuO hierarchical nanocomposites (HNCs) nonenzymatic glucose electrodes with different thicknesses were fabricated by coelectrospinning and compared with 3D mixed ZnO/CuO nanowires (NWs) and pure CuO NWs electrodes. The structural characterization revealed that the ZnO-CuO HNCs were composed of the ZnO and CuO mixed NWs trunk (~200 nm), whose outer surface was attached with small CuO nanoparticles (NPs). Moreover, a good synergetic effect between CuO and ZnO was confirmed. The nonenzymatic biosensing properties of as prepared 3D porous electrodes based on fluorine doped tin oxide (FTO) were studied and the results indicated that the sensing properties of 3D porous ZnO-CuO HNCs electrodes were significantly improved and depended strongly on the thickness of the HNCs. At an applied potential of + 0.7 V, the optimum ZnO-CuO HNCs electrode presented a high sensitivity of 3066.4 μAmM(-1)cm(-2), the linear range up to 1.6 mM, and low practical detection limit of 0.21 μM. It also showed outstanding long term stability, good reproducibility, excellent selectivity and accurate measurement in real serum sample. The formation of special hierarchical heterojunction and the well-constructed 3D structure were the main reasons for the enhanced nonenzymatic biosensing behavior.
Effects of intensity of arm training on hemiplegic upper extremity motor recovery in stroke patients: a randomized controlled trial.

OBJECTIVE
To investigate the effects of different intensities of arm rehabilitation training on the functional recovery of hemiplegic upper extremity.


DESIGN
A randomized controlled trial.


INTERVENTIONS
Thirty-two stroke patients meeting the enrolment criteria were randomly divided into three groups: group A (n = 11), group B (n = 10) and group C (n = 11). Each group received arm training for 1 hour, 2 hours and 3 hours a day respectively, 5 days per week, for a period of six weeks.


MAIN MEASURES
Motor function was assessed by Fugl-Meyer Assessment, Action Research Arm Test and Barthel Index, carried out before treatment, two weeks, four weeks and six weeks after treatment.


RESULTS
When comparing the three groups, the Fugl-Meyer Assessment improvement was more significant in group C (20.50 ± 7.84) than that in group A (11.90 ± 6.52 ) and group B (13.80 ± 6.41) after four weeks of treatment (P < 0.05). The Action Research Arm Test score improvement was more significant in group C (7.30 ± 2.95) than in group A (3.30 ± 2.91 ) (P < 0.05). After six weeks of treatment, the Fugl-Meyer Assessment and Action Research Arm Test score improvements were more significant in group C (24.50 ± 7.96, 10.90 ± 3.60) and group B (19.70 ± 7.09, 8.70 ± 4.62) than in group A (13.00 ± 6.38, 5.30 ± 3.40) (P < 0.05). There were no significant differences of Barthel Index among the three groups (P > 0.05). In each group, Fugl-Meyer Assessment, Action Research Arm Test and Barthel Index scores increased significantly after six weeks of treatment (P < 0.05).


CONCLUSIONS
An increase in the intensity of arm training might improve the motor function of the arm after stroke.
Feasibility study of noninvasive ventilation with helium-oxygen gas flow for chronic obstructive pulmonary disease during exercise.

BACKGROUND
Individually, noninvasive ventilation (NIV) and helium-oxygen gas mixtures (heliox) diminish ventilatory workload and improve exercise tolerance in patients with chronic obstructive pulmonary disease (COPD). NIV in combination with heliox may have additive effects on exercise tolerance in severe COPD.


METHODS
We assessed the safety, tolerability, and efficacy of heliox and NIV during exercise in patients with severe COPD.


SETTING
Pulmonary rehabilitation facility in an academic tertiary-care medical center.


PROTOCOL
Twelve patients with severe COPD were enrolled. Using a sequential randomized placebo-controlled crossover study design, the patients performed 4 separate constant-work stationary bicycle cardiopulmonary exercise studies at 80% of maximal workload during application of sham NIV, NIV, 60:40 heliox with sham NIV, and 60:40 heliox with NIV. Tolerability, safety, and exercise duration as determined by constant-work cardiopulmonary exercise test were the primary outcome measures. Secondary outcome measures at peak exercise and iso-time included rate of perceived exertion, dyspnea, leg pain, heart rate, respiratory rate, systolic and diastolic blood pressure, tympanic temperature, and oxyhemoglobin saturation.


RESULTS
No adverse effects occurred during or after application of NIV, heliox, or NIV with heliox. Exercise duration using heliox with NIV was significantly longer than both heliox (P = .01) and NIV (P = .007), but not placebo (P = .09). Relative to placebo, all treatment arms permitted lower respiratory rates at peak exercise. Heliox, with or without NIV, was associated with significant improvements in oxyhemoglobin saturation at peak exercise, relative to placebo or NIV alone.


CONCLUSIONS
The adjunctive use of NIV with heliox during exercise proved both safe and tolerable in patients with severe COPD. The lack of demonstrable efficacy to any of the treatment arms relative to placebo (P = .09) may be the result of the small sample size (ie, type 2 error)-a conclusion emphasized by the large standard deviations and differences in treatment group variances in exercise duration alone.

The Centers for Medicare and Medicaid Services (CMS) community-acquired pneumonia core measures lead to unnecessary antibiotic administration by emergency physicians.

OBJECTIVES
The objectives were to assess emergency physician (EP) understanding of the Centers for Medicare and Medicaid Services (CMS) core measures for community-acquired pneumonia (CAP) guidelines and to determine their self-reported effect on antibiotic prescribing patterns.


METHODS
A convenience sample of EPs from five medical centers in North Carolina was anonymously surveyed via a Web-based instrument. Participants indicated their level of understanding of the CMS CAP guidelines and the effects on their prescribing patterns for antibiotics.


RESULTS
A total of 121 EPs completed the study instrument (81%). All respondents were aware of the CMS CAP guidelines. Of these, 95% (95% confidence interval [CI] = 92% to 98%) correctly understood the time-based guidelines for antibiotic administration, although 24% (95% CI = 17% to 31%) incorrectly identified the onset of this time period. Nearly all physicians (96%; 95% CI = 93% to 99%) reported institutional commitment to meet these core measures, and 84% (95% CI = 78% to 90%) stated that they had a department-based CAP protocol. More than half of the respondents (55%; 95% CI = 47% to 70%) reported prescribing antibiotics to patients they did not believe had pneumonia in an effort to comply with the CMS guidelines, and 42% (95% CI = 34% to 50%) of these stated that they did so more than three times per month. Only 40% (95% CI = 32% to 48%) of respondents indicated a belief that the guidelines improve patient care. Of those, this was believed to occur by increasing pneumonia awareness (60%; 95% CI = 52% to 68%) and improving hospital processes when pneumonia is suspected (86%; 95% CI = 80% to 92%).


CONCLUSIONS
Emergency physicians demonstrate awareness of the current CMS CAP guidelines. Most physicians surveyed reported the presence of institutional protocols to increase compliance. More than half of EPs reported that they feel the guidelines led to unnecessary antibiotic usage for patients who are not suspected to have pneumonia. Only 40% of EPs believe that CAP awareness and expedient care resulting from these guidelines has improved overall pneumonia-related patient care. Outcome-based data for non-intensive care unit CAP patients are lacking, and EPs report that they prescribe antibiotics when they may not be necessary to comply with existing guidelines.
The impact of atmospheric deposition on the aquatic ecosystem with special emphasis on lake productivity, Newfoundland, Canada

To document and analyze the ecosystem response to acidification and possible concurrent heavy metal enrichment process, a detailed paleoecological study was conducted in Lake 817, a small, and sensitive, second order lake, in insular Newfoundland. The inferred pH history of the lake was recreated using the region-specific equation relating fossil diatom taxa to pH. The profile demonstrated a fairly stable pH history over the bottom 22 cm of the sediment core with an appreciable pH decline in the upper 5 cm. The decrease of inferred pH began in the 1930's (ca. 1931 to 1944) and the lowest inferred pH value (5.3) was observed in the surface stratum. The decreasing pH trend (0.4 unit; 5.7 to 5.3) between ca. 1931 and 1985 correlated well with changes in sediment chemistry. Major elements (P, Mg, Ca, Na, and K) showed significant decrease in deposition primarily in the upper 3 cm level (ca. 1944). The profiles of selected metals (Fe, Mn, Cr, Cu, Zn, Pb, Co, Hg, As, and Ni) indicated that the deposition of these elements increased noticeably, primarily in the upper 3 cm level. The enrichment of Pb began earlier, about 50 years ago (1931 to 1944). The stratigraphy of fossil pigments (chlorophyll derivatives and total carotenoids) demonstrated a general trend of increasing accumulation upwards in the core while the only significant decrease in pigments was observed in the recent strata (ca. between 1957 to 1985). The most dramatic decrease of primary production occurred during ca. 1957 to 1974 period and this phenomenon was associated with increased levels of heavy metals. It seems that primary production in oligotrophic, acidifying lakes in Newfoundland is controlled more by nutrients loading and the possible toxicological effects of heavy metals, than directly by water acidity.
Embedded web server application based automation and monitoring system

Current Home Automation and Process Monitoring Systems make use of PC-based servers. The Appliances in case of Home Automation and processes in case of Process Monitoring System are interfaced to these servers. As a result, it becomes necessary to keep the servers on all the time, which ultimately increases the producing cost. This shortcoming can be overcome by using an Embedded Web Server in place of a PC-based Server. Embedded Web Server is a single-chip implementation of the Ethernet networking standard. By embedding Ethernet onto a device, it has the capability to communicate via Ethernet without using a computer. The server enables Web access to the automation and monitoring system and provides a scalable networking solution that is optimized for instrumentation, industrial and home automation. The users can browse the home page of the system using web browser, and control the household appliances and enquire about their operational status. This paper proposes a development of such a low-cost electronic prototype, which is designed for monitoring and controlling home appliances via web browser. At the same time, users can monitor the security situation at home in real-time through different sensors installed at home.
Structural and functional bases for individual differences in motor learning.

People vary in their ability to learn new motor skills. We hypothesize that between-subject variability in brain structure and function can explain differences in learning. We use brain functional and structural MRI methods to characterize such neural correlates of individual variations in motor learning. Healthy subjects applied isometric grip force of varying magnitudes with their right hands cued visually to generate smoothly-varying pressures following a regular pattern. We tested whether individual variations in motor learning were associated with anatomically colocalized variations in magnitude of functional MRI (fMRI) signal or in MRI differences related to white and grey matter microstructure. We found that individual motor learning was correlated with greater functional activation in the prefrontal, premotor, and parietal cortices, as well as in the basal ganglia and cerebellum. Structural MRI correlates were found in the premotor cortex [for fractional anisotropy (FA)] and in the cerebellum [for both grey matter density and FA]. The cerebellar microstructural differences were anatomically colocalized with fMRI correlates of learning. This study thus suggests that variations across the population in the function and structure of specific brain regions for motor control explain some of the individual differences in skill learning. This strengthens the notion that brain structure determines some limits to cognitive function even in a healthy population. Along with evidence from pathology suggesting a role for these regions in spontaneous motor recovery, our results also highlight potential targets for therapeutic interventions designed to maximize plasticity for recovery of similar visuomotor skills after brain injury.

Robust Model Predictive Control : A Survey

This paper gives an overview of robustness in Model Predictive Control (MPC). After reviewing the basic concepts of MPC, we survey the uncertainty descriptions considered in the MPC literature, and the techniques proposed for robust constraint handling, stability, and performance. The key concept of “closedloop prediction” is discussed at length. The paper concludes with some comments on future research directions.
Multiple-model tracking for the detection of lane change maneuvers

Volkswagen research has developed a system for vehicle surround perception which integrates different sensor data of the environment into a combined description by using a single model Kalman tracker. This paper deals with the extension of the tracking system by means of an interacting multiple-model algorithm (IMM) to improve the tracking stability during curves and to detect lane changes of the observed target vehicle. The applied IMM-tracker uses specialized models for lateral and longitudinal motion that are partly affected by curvature estimation. The technique is tested with recorded sequences of measurement data and shows robust tracking and well-fitting classification of the dynamical behavior of the targets.
Stock Index Forecasting Using PSO Based Selective Neural Network Ensemble

Stock market analysis is one of the most important and hard problems in finance analysis field. Recently, the usage of intelligent systems for stock market prediction has been widely established. In this paper, a PSO based selective neural network ensemble (PSOSEN) algorithm is proposed, which is used for the Nasdaq-100 index of Nasdaq Stock Market and the S&P CNX NIFTY stock index analysis. In the algorithm, each neural network is obtained by bagging and is trained by PSO algorithm, and then the networks selected according to the pre-set threshold are combined. Experimental results show that the improved algorithm is effective and outperforms GA based selective ensemble (GASEN) algorithm for the stock index forecasting problems.
Effectiveness of mobilisation of the upper cervical region and craniocervical flexor training on orofacial pain, mandibular function and headache in women with TMD. A randomised, controlled trial.

BACKGROUND
Studies exploring interventions targeting the cervical spine to improve symptoms in patients with temporomandibular disorders (TMD) are limited.


OBJECTIVES
To determine whether mobilisation of the upper cervical region and craniocervical flexor training decreased orofacial pain, increased mandibular function and pressure pain thresholds (PPTs) of the masticatory muscles and decreased headache impact in women with TMD when compared to no intervention.


METHODS
In a single-blind randomised controlled trial, 61 women with TMD were randomised into an intervention group (IG) and a control group (CG). The IG received upper cervical mobilisations and neck motor control and stabilisation exercises for 5 weeks. The CG received no treatment. Outcomes were collected by a blind rater at baseline and 5-week follow-up. Orofacial pain intensity was collected once a week. A mixed ANOVA and Cohen's d were used to determine differences within/between groups and effect sizes.


RESULTS
Pain intensity showed significant time-by-group interaction (P < 0.05), with significant between-group differences at four and five weeks (P < 0.05), with large effect sizes (d > 0.8). The decrease in orofacial pain over time was clinically relevant only in the IG. Change in headache impact was significantly different between groups, and the IG showed a clinically relevant decrease after the treatment. No effects were found for PPT or mandibular function.


CONCLUSION
Women with TMD reported a significant decrease in orofacial pain and headache impact after 5 weeks of treatment aimed at the upper cervical spine compared to a CG.
