A Tunable Via-Patch Loaded PIFA With Size Reduction

A novel tunable planar inverted-F antenna (PIFA) is described. A via-patch is introduced under the main radiating element to create a capacitive coupling effect and lower the operating frequency. The antenna size is reduced by half when compared to the conventional PIFA. Incorporating with an L-shaped opening on the ground plane, the proposed via-patch loaded PIFA exhibits a 10-dB return-loss bandwidth of 8.91% for 2.4 GHz ISM band applications. In the proposed approach, the capacitive patch is connected to the ground through a via while a coaxial feed is directly connected to the radiating element. This is different from other capacitive-loading, size-reduction schemes in which the capacitive patch is connected to the coaxial feed, thus not able to provide frequency tuning. By simply replacing the via in our antenna with a screw and adjusting the height of the via-patch by turning the screw, a tuning range of 0.8 GHz from 2.5-3.3 GHz can be achieved. This makes the proposed PIFA a convenient tunable small antenna. Both simulation and measurement results are presented together with parametric studies on the via-patch and L-shaped opening ground plane
Clinical consequences of delayed addition of adalimumab to methotrexate therapy over 5 years in patients with rheumatoid arthritis.

OBJECTIVE
This Year 5 analysis of an open-label extension (OLE) study assessed radiographic progression, clinical efficacy, and safety of adalimumab with concomitant methotrexate (MTX) for patients with active rheumatoid arthritis.


METHODS
In a double-blind study (DE019, NCT00195702), inadequate responders to MTX were randomized to MTX plus either adalimumab 40 mg eow, adalimumab 20 mg weekly, or placebo for 52 weeks. Eligible patients entered an ongoing OLE and received adalimumab 40 mg eow plus MTX. Longterm efficacy and safety were evaluated.


RESULTS
Of 457 patients who had enrolled in the OLE, 304 remained in the study at Year 5, including 112, 107, and 85 from the original adalimumab 40 mg, adalimumab 20 mg, and placebo groups, respectively. Year 5 radiographs demonstrated mean changes in modified total Sharp score for the original adalimumab 40 mg eow and 20 mg weekly groups of 0.8 and 2.6, respectively, versus 3.9 for placebo; 58% from the adalimumab 40 mg eow group had no radiographic progression versus 40% of those who initially received placebo. Of patients who received adalimumab 40 mg eow for 5 years, 26.1% achieved clinical remission (Disease Activity Score 28-joint count < 2.6), had no radio graphic progression (change in modified total Sharp score ≤ 0.5), and had normal function (Health Assessment Questionnaire ≤ 0.5), versus 11.9% of those who initially received placebo. Serious infection rate for 553 patients who received at least one dose of adalimumab was 4.4/100 patient-years.


CONCLUSION
A 52-week delay in adding adalimumab to MTX led to worse radiographic, functional, and clinical outcomes at Year 5 for most patients who initially received placebo instead of adalimumab.
Eye tracking the user experience - An evaluation of ontology visualization techniques

Various ontology visualization techniques have been developed over the years, offering essential interfaces to users for browsing and interacting with ontologies, in an effort to assist with ontology understanding. Yet few studies have focused on evaluating the usability of existing ontology visualization techniques. This paper presents an eye-tracking user study that evaluates two commonly used ontology visualization techniques, namely, indented list and graph. The eye-tracking experiment and analysis presented in this paper complements the set of existing evaluation protocols for ontology visualization. In addition, the results found from this study contribute to a greater understanding of the strengths and weaknesses of the two visualization techniques, and in particular, how and why one is more effective than the other. Based on approximately 500MB of eye movement data containing around 30 million rows of gaze data generated by a Tobii eye tracker, we found evidence suggesting indented lists are more efficient at supporting information searches and graphs are more efficient at supporting information processing.

Employee Turnover : A Novel Prediction Solution with Effective Feature Selection

This study proposed to address a new method that could select subsets more efficiently. In addition, the reasons why employers voluntarily turnover were also investigated in order to increase the classification accuracy and to help managers to prevent employers’ turnover. The mixed subset selection used in this study combined Taguchi method and Nearest Neighbor Classification Rules to select subset and analyze the factors to find the best predictor of employer turnover. All the samples used in this study were from industry A, in which the employers left their job during 1st of February, 2001 to 31st of December, 2007, compared with those incumbents. The results showed that through the mixed subset selection method, total 18 factors were found that are important to the employers. In addition, the accuracy of correct selection was 87.85% which was higher than before using this subset selection (80.93%). The new subset selection method addressed in this study does not only provide industries to understand the reasons of employers’ turnover, but also could be a long-term classification prediction for industries.

Separating forms of neglect using the Apples Test: validation and functional prediction in chronic and acute stroke.

OBJECTIVE
We report data on the validation and functional correlates of Apples Test, which attempts to differentiate between different forms of unilateral neglect.


METHOD
Study 1 presents data from 25 participants with chronic brain lesions who completed the Apples Test and another standard measure of neglect (Star Cancellation). The patients' performance relative to 86 controls was assessed and their relative performance across the two tests compared. Study 2 recruited 115 acute hospital stroke patients who completed the Apples Test as part of the Birmingham University Cognitive Screen procedure. We assessed the relations between the different forms of neglect. Study 3 examined neglect type (as measured by the Apples Test) among the acute stroke group in relation to their activities of daily living abilities and affect.


RESULTS
In Study 1 Apples Test scores correlated with Star Cancellation performance, while also differentiating between neglect across the page and neglect of parts of objects. Study 2 confirmed the dissociation from Study 1. "Pure" forms of each type of neglect were equally prevalent after right and left hemisphere lesions, while the presence of both deficits was associated with right hemisphere damage. Study 3 showed that each form of neglect also correlated with other measures of cognition. When compared with pure page-based neglect, object-centered neglect was associated with a lower Barthel score (p < .001), while patients with both forms of neglect had higher level of depression (p < .001) than those with the pure forms.


CONCLUSIONS
We conclude that the Apples test provides a clinically applicable measure of different forms of neglect. In addition it is a useful predictor of functional outcome. We discuss the nature of the two forms of neglect diagnosed by the test and the functional implications.
Wear behavior of uncoated carbide inserts under dry, wet and cryogenic cooling conditions in turning C-60 steel

Environmental pollution, inconveniences and health hazards due to conventional application of cutting fluids essentially required for cooling and lubrication have been a great concern of the industries and the modern societies. Further they are also ineffective in controlling the high cutting temperature and rapid tool wear. One of the possible and potential techniques to overcome such problem is application of cryogenic cooling particularly by liquid nitrogen specially where the cutting temperature is a major constraint in achieving high productivity and job quality. The present work deals with experimental investigation in the role of cryogenic cooling by liquid nitrogen jets on tool wear, dimensional deviation and surface finish in turning of C60 steel at industrial speed-feed combination by uncoated carbide inserts (SNMG and SNMM) of different geometric configurations. The results have been compared with dry and wet machining. The results of the present work indicate substantial reduction in tool wear, which enhanced the tool life, dimensional accuracy and surface finish. This may be mainly attributed to reduction in cutting zone temperature and favourable change in the chip-tool interaction. Further it was evident that machining with soluble oil cooling failed to provide any significant improvement in tool life, rather surface finish deteriorated. Furthermore, it provides environment friendliness and improves the machinability characteristics.
A Ka-Band patch antenna array with improved circular polarization

In this paper, a Ka-Band patch sub-array structure for millimeter-wave phased array applications is demonstrated. The conventional corner truncated patch is modified to improve the impedance and CP bandwidth alignment. A new sub-array feed approach is introduced to reduce complexity of the feed line between elements and increase the radiation efficiency. A sub-array prototype is built and tested. Good agreement with the theoretical results is obtained.
14.3 Early cardiovascular risk assessment in patients with juvenile idiopathic arthritis

Background Inflammation has emerged as an important factor that contributes to the development of atherosclerosis and is associated with increased cardiovascular risk. Juvenile idiopathic arthritis (JIA) is a chronic inflammatory condition with its origin in childhood. Its adult form, rheumatoid arthritis, has been associated with an excess of cardiovascular disease even after adjustment for traditional risk factors.
Effects of intensive blood-pressure control in type 2 diabetes mellitus.

BACKGROUND
There is no evidence from randomized trials to support a strategy of lowering systolic blood pressure below 135 to 140 mm Hg in persons with type 2 diabetes mellitus. We investigated whether therapy targeting normal systolic pressure (i.e., <120 mm Hg) reduces major cardiovascular events in participants with type 2 diabetes at high risk for cardiovascular events.


METHODS
A total of 4733 participants with type 2 diabetes were randomly assigned to intensive therapy, targeting a systolic pressure of less than 120 mm Hg, or standard therapy, targeting a systolic pressure of less than 140 mm Hg. The primary composite outcome was nonfatal myocardial infarction, nonfatal stroke, or death from cardiovascular causes. The mean follow-up was 4.7 years.


RESULTS
After 1 year, the mean systolic blood pressure was 119.3 mm Hg in the intensive-therapy group and 133.5 mm Hg in the standard-therapy group. The annual rate of the primary outcome was 1.87% in the intensive-therapy group and 2.09% in the standard-therapy group (hazard ratio with intensive therapy, 0.88; 95% confidence interval [CI], 0.73 to 1.06; P=0.20). The annual rates of death from any cause were 1.28% and 1.19% in the two groups, respectively (hazard ratio, 1.07; 95% CI, 0.85 to 1.35; P=0.55). The annual rates of stroke, a prespecified secondary outcome, were 0.32% and 0.53% in the two groups, respectively (hazard ratio, 0.59; 95% CI, 0.39 to 0.89; P=0.01). Serious adverse events attributed to antihypertensive treatment occurred in 77 of the 2362 participants in the intensive-therapy group (3.3%) and 30 of the 2371 participants in the standard-therapy group (1.3%) (P<0.001).


CONCLUSIONS
In patients with type 2 diabetes at high risk for cardiovascular events, targeting a systolic blood pressure of less than 120 mm Hg, as compared with less than 140 mm Hg, did not reduce the rate of a composite outcome of fatal and nonfatal major cardiovascular events.

Twin-Buck Converter With Zero-Voltage Transition

This paper proposes a twin-buck converter with zero-voltage transition (ZVT). The converter comprises two identical buck conversion units employing power MOSFETs as the active power switches with an interleaved inductor. The ZVT is accomplished by resonating the currents between the interleaved inductor and the parasitic capacitances of the power MOSFETs. The detailed circuit operations and analysis are provided. A laboratory circuit rated at 300 W is designed and tested. Experimental results show that the switching losses can be effectively reduced by ZVT of the active power switches, accompanied by the reduced reverse recovery loss of freewheeling diodes.
Does ligation of the intersphincteric fistula tract raise the bar in fistula surgery?

BACKGROUND
The ligation of the intersphincteric fistula tract procedure has been reported to have high cure rates, with minimal impairment of continence.


OBJECTIVE
The aim of this study was to evaluate the success rates and functional outcome after the ligation of the intersphincteric fistula tract procedure.


DESIGN
This study was performed as a retrospective review.


SETTINGS
The study was conducted at the Division of Colon and Rectal Surgery, University of Minnesota and at affiliated hospitals in Minneapolis and St. Paul, Minnesota, between March 2007 and September 2011.


PATIENTS
Ninety-three patients with transsphincteric cryptoglandular anal fistula were included.


INTERVENTIONS
Ligation of the intersphincteric fistula tract procedure was performed.


MAIN OUTCOME MEASURES
Failure was defined as persistent or recurrent drainage, air leakage from a patent external opening, or intersphincteric incision or reoperation for recurrent fistula. Success was defined as healing of the external fistula opening and intersphincteric incision. Patients were followed up with a questionnaire to assess the recurrence rate and the Wexner incontinence score.


RESULTS
The median follow-up time for was 19 months (range, 4-55). Thirty patients (32%) had a history of previous surgery for their fistula. The success rate of fistula healing was 40% after the first ligation of the intersphincteric fistula tract procedure. When including patients with repeat ligation of the intersphincteric fistula tract and subsequent intersphincteric fistulotomy after ligation of the intersphincteric fistula tract repair, the success rates were 47% and 57%. Patients with successful fistula closure reported a mean Cleveland Clinic Florida Fecal Incontinence score of 1.0 (SD 2.3). No predictor for successful fistula closure was found.


LIMITATIONS
Retrospective design, limited accuracy of diagnosing fistula failure, and lack of baseline continence were limitations of this study.


CONCLUSION
The present study indicates that the ligation of the intersphincteric fistula tract procedure for transsphincteric fistulas has a significant risk for failure but good functional outcome in patients with no recurrence.
Free Web-based Personal Health Records: An Analysis of Functionality

This paper analyzes and assesses the functionality of free Web-based PHRs as regards health information, user actions and connection with other tools. A systematic literature review in Medline, ACM Digital Library, IEEE Digital Library and ScienceDirect was used to select 19 free Web-based PHRs from the 47 PHRs identified. The results show that none of the PHRs selected met 100 % of the 28 functions presented in this paper. Two free Web-based PHRs target a particular public. Around 90 % of the PHRs identified allow users throughout the world to create their own profiles without any geographical restrictions. Only half of the PHRs selected provide physicians with user actions. Few PHRs can connect with other tools. There was considerable variability in the types of data included in free Web-based PHRs. Functionality may have implications for PHR use and adoption, particularly as regards patients with chronic illnesses or disabilities. Support for standard medical document formats and protocols are required to enable data to be exchanged with other stakeholders in the health care domain. The results of our study may assist users in selecting the PHR that best fits their needs, since no significant connection exists between the number of functions of the PHRs identified and their popularity.
Restoration of gait and motor recovery by functional electrical stimulation therapy in persons with stroke.

PURPOSE
To evaluate the clinical efficacy of functional electrical stimulation (FES) therapy of the tibialis anterior (TA) muscle on gait restoration and enhancing motor recovery with stroke patients.


METHOD
Thirty hemiparetic participants with spastic foot-drop impairments who were at least 3 months post-stroke were recruited from a rehabilitation institute and were assigned either to a control group or a FES group. Both the groups participated in a conventional stroke rehabilitation program for 60 min per day, 5 days a week, for 12-weeks. The FES group received the electrical stimulation to the TA muscle for correction of foot-drop.


RESULTS
Functional electric stimulation (FES) resulted in a 26.3% (p < 0.001) improvement of walking speed measured with 10-m walkway, whereas the improvement in the control group was only 11.5% (p < 0.01). The FES group also showed significantly greater improvements compared to control group in other gait parameters (e.g. cadence, step length), physiological cost index (PCI), ankle range of motion, spasticity of calf muscle, Fugl-Meyer scores, and the maximum value of the root mean square (RMS(max)), which reflects the capacity of the muscle output.


CONCLUSIONS
These findings suggest that, the FES therapy combined with conventional therapy treatment more effectively improves the walking ability and enhances the motor recovery when compared with conventional therapy alone in stroke survivors.
Gamification of M-learning Mandarin as second language

This paper presents some empiric results on teaching basic Mandarin as second language to college students using gamification approach. This study shows some evidences that gamification outperform non-gamification teaching method in related to learning concentration, skills, feedback, and immersion. However, gamification method has some drawbacks in related to compliance of quiz difficulty with the level/learning progress, clarity of overall learning goal, and clarity of goal at each level. These strength and drawbacks of gamification design are expected to give valuable information for teachers in delivering Mandarin as second language.
Optimal dose period for indisetron tablets for preventing chemotherapy-induced nausea and vomiting with modified FOLFOX6: a randomized pilot study.

BACKGROUND
Indisetron is a serotonin (5-hydroxytryptamine type 3) receptor antagonist that also antagonizes 5-hydroxytryptamine type 4 receptors. We designed a pilot study in order to explore the optimal dosing period for indisetron during modified FOLFOX6 (mFOLFOX6).


PATIENTS AND METHODS
Forty-two chemotherapy-naive patients with advanced colorectal cancer scheduled to receive mFOLFOX6 were randomly assigned to either a 1- or 3-day indisetron regimen arm. The primary endpoint was complete protection from vomiting.


RESULTS
Proportions of patients with complete protection from vomiting were 85.7% [95% confidence interval (CI) 63.7-97.0] with the 3-day regimen and 81.0% (95% CI 58.1-94.6) with the 1-day regimen. Proportions of patients with complete protection from nausea were 47.6% in each arm (95% CI 25.7-70.2). No rescue therapy rates were 66.7% (95% CI 43.0-85.4) versus 57.1% (95% CI 34.0-78.2). No severe adverse events were observed in either arm.


CONCLUSION
Both 1- and 3-day indisetron regimens were feasible for preventing nausea and vomiting induced by mFOLFOX6.
An empirical assessment of the EFQM Excellence Model : Evaluation as a TQM framework relative to the MBNQA Model

Total quality management (TQM) is an approach to management embracing both social and technical dimensions aimed at achieving excellent results, which needs to be put into practice through a specific framework. Nowadays, quality award models, such as the Malcolm Baldrige National Quality Award (MBNQA) and the European Foundation for Quality Management (EFQM) Excellence Model, are used as a guide to TQM implementation by a large number of organizations. Nevertheless, there is a paucity of empirical research confirming whether these models clearly reflect the main premises of TQM. The purpose of this paper is to analyze the extent to which the EFQM Excellence Model captures the main assumptions involved in the TQM concept, that is, the distinction between technical and social TQM issues, the holistic interpretation of TQM in the firm, and the causal linkage between TQM procedures and organizational performance. Based on responses collected from managers of 446 Spanish companies by means of a structured questionnaire, we find that: (a) social and technical dimensions are embedded in the model; (b) both dimensions are intercorrelated; (c) they jointly enhance results. These findings support the EFQM Excellence Model as an operational framework for TQM, and also reinforce the results obtained in previous studies for the MBNQA, suggesting that quality award models really are TQM frameworks. 2008 Elsevier B.V.
