Background—
Specific noninvasive signal processing was applied to identify drivers in distinct categories of persistent atrial fibrillation (AF).

Methods and Results—

In 103 consecutive patients with persistent AF, accurate biatrial geometry relative to an array of 252 body surface electrodes was obtained from a noncontrast computed tomography scan. The reconstructed unipolar AF electrograms acquired at bedside from multiple windows (duration, 9±1 s) were signal processed to identify the drivers (focal or reentrant activity) and their cumulative density map. The driver domains were catheter ablated by using AF termination as the procedural end point in comparison with the stepwise-ablation control group. The maps showed incessantly changing beat-to-beat wave fronts and varying spatiotemporal behavior of driver activities. Reentries were not sustained (median, 2.6 rotations lasting 449±89 ms), meandered substantially but recurred repetitively in the same region. In total, 4720 drivers were identified in 103 patients: 3802 (80.5%) reentries and 918 (19.5%) focal breakthroughs; most of them colocalized. Of these, 69% reentries and 71% foci were in the left atrium. Driver ablation alone terminated 75% and 15% of persistent and long-lasting AF, respectively. The number of targeted driver regions increased with the duration of continuous AF: 2 in patients presenting in sinus rhythm, 3 in AF lasting 1 to 3 months, 4 in AF lasting 4 to 6 months, and 6 in AF lasting longer. The termination rate sharply declined after 6 months. The mean radiofrequency delivery to AF termination was 28±17 minutes versus 65±33 minutes in the control group (
P
<0.0001). At 12 months, 85% patients with AF termination were free from AF, similar to the control population (87%,);
P
=not significant.

Conclusions—
Persistent AF in early months is maintained predominantly by drivers clustered in a few regions, most of them being unstable reentries.

Published: July 2014

Background

The incidence of acute kidney injury (
AKI
) requiring dialysis in hospitalized patients is increasing; however, information on the long‐term incidence of stroke in patients surviving to discharge after recovering from
AKI
after dialysis has not been reported.

Methods and Results

Patients that survived after recovery from dialysis‐requiring
AKI
during index hospitalizations from 1999 to 2008 were identified in nationwide administrative registries. The risk of de novo stroke and death were analyzed with time‐varying Cox proportional hazard models. The results were validated by a critical care database. We enrolled 4315 patients in the
AKI
‐recovery group (men, 57.7%; mean age, 62.8±16.8 years) and matched 4315 control subjects as the non‐
AKI
group by propensity scores. After a median follow‐up period of 3.36 years, the incident stroke rate was 15.6 per 1000 person‐years. The
AKI
‐recovery group had higher risk (hazard ratio: 1.25;
P
=0.037) and higher severity of stroke events than the non‐
AKI
group, regardless of progression to subsequent chronic kidney disease. The rate of incident stroke was not statistically different in those with diabetes alone (without
AKI
) and in those with
AKI
alone (without diabetes) after hospital discharge (
P
=0.086). Furthermore, the risk of mortality in the
AKI
‐recovery group was higher than in the non‐
AKI
group (
hazard ratio:
2.4;
P
<0.001).

Conclusions

The patients who recovered from
AKI
had a higher incidence of developing incident stroke and mortality than the patients without
AKI
, and the impact was similar to diabetes. Our results suggest that a public health initiative is needed to enhance postdischarge follow‐up of renal function and to control the subsequent incidence of stroke among patients who recover from
AKI
after dialysis.

Abstract
Station siting for environmental observing networks is usually made subjectively, which suggests that the monitoring goals for the network may not be met optimally or cost effectively. In Antarctica, where harsh weather conditions make it difficult to install and maintain stations, practical considerations have largely guided the development of the staffed and automated weather station network. The current network coverage in Antarctica is evaluated as a precursor to optimal network design. The Antarctic Mesoscale Prediction System (AMPS) 0000 UTC analysis is used for 4 years (2008–12) with 15-km horizontal grid spacing, and results show that AMPS reproduces the daily correlations in surface temperature and pressure observed between weather stations across the continent. Temperature correlation length scales are greater in East Antarctica than in West Antarctica (including the Antarctic Peninsula), implying that more stations per unit area are needed to sample weather in West Antarctica compared to East Antarctica. There is variability in the temperature correlation length scales within these regions, emphasizing the need for objective studies such as this one for determining the impact of current and new stations. Further analysis shows that large regions are not well sampled by the current network, particularly on daily time scales. Observations are particularly limited in West Antarctica. Combined with the shorter temperature correlation length scales, this implies that West Antarctica is a compelling location for implementing an objective, optimal network design approach.
Clear Cell Carcinoma of the Base of the Tongue
Authors: Watanabe Kenichi , Okumura Yuri , Hashimoto Ken , Suzuki Takashi 
Published: July 2014

Objective: Clear cell carcinoma (CCC) is a rare, low-grade malignant neoplasm of minor salivary glands. Clear cell carcinoma is composed of monomorphic clear cells that contain glycogen within a hyalinized stroma. The microscopic diagnosis can be challenging, and the treatment strategy has not been established. Methods: We report a case of a 56-year-old woman with CCC in the base of the tongue. A literature review, including 22 published cases and our case, was performed to clarify the clinical characteristics of CCC in the base of the tongue. Results: The exophytic tumor showed no infiltration to the neighboring tissues. She underwent a local excision en bloc transorally and is free of the disease 15 months after surgery. In our review of 23 cases of CCC in the base of the tongue, 21 cases received surgical excision for the purpose of the primary treatment modality. The fact that the distinctive features of restricted site-related symptoms and the rare presentation of pain emerged was similar to previously reported cases of CCC. A relatively good prognosis was still indicated. Conclusion: We reveal the features of the unusual occurrence of CCC in the base of the tongue and consider the appropriate surgical approach for primary treatment.

Published: July 2014

Background: Glenoid bone loss is a factor that has been inversely associated with the success of shoulder instability repair. Recently, patients with an anterior labroligamentous periosteal sleeve avulsion (ALPSA) lesion have also been identified as having a higher failure rate after surgical repair. Purpose: To determine differences in the amount of glenoid bone loss and to compare demographic factors of instability in patients with and without ALPSA tears. Study Design: Case-control study; Level of evidence, 3. Methods: Over a 3-year period, all patients (N = 83) who were treated for anterior shoulder instability at a single institution were reviewed retrospectively. A total of 39 (47%) were identified as having an ALPSA lesion and 44 (53%) as having no ALPSA tear. Glenoid bone loss was determined in 2 ways: (1) radiographically by 3-dimensional computed tomography (3D CT) (humeral head digitally subtracted by 3 blinded observers) and (2) with arthroscopic techniques at the time of surgery. Demographic data such as the time from the initial instability event to advanced imaging and surgery were noted. These data were then analyzed with the Student t test to determine any significant differences between the 2 groups. Results: The patients with an ALPSA lesion had more preoperative instability events than those without (8.2 vs 3.6, respectively; P = .04). The mean glenoid bone loss measured by 3D CT was 12.7% (range, 0%-22.3%) for those with ALPSA tears versus 6.25% (range, 0%-23.1%) for those without ( P = .002). The mean duration of total instability for those with ALPSA tears was 42.9 months versus 46.3 months for those without ( P = .95). Lastly, the mean bone loss based on arthroscopic measures was 11.4% for patients with ALPSA tears and 4.3% for those without ALPSA tears ( P = .017). From the existing magnetic resonance imaging/arthrography scans reviewed, 82% of patients could be correctly identified as having an ALPSA lesion. Conclusion: Patients with anterior shoulder instability who have an ALPSA lesion have nearly twice the amount of glenoid bone loss as those with a standard Bankart tear (no ALPSA lesion). Patients with ALPSA lesions had statistically more instability events, and this may be an additional factor in either developing an ALPSA lesion or glenoid bone loss or both.

Abstract

Background
All sonomarkers used to screen for fetal hemoglobin (Hb) Bart’s disease need high expertise, preventing them from being widely used. Fetal cardiac diameter to biparietal diameter (C/B) ratio is a simple marker which has never been evaluated for its effectiveness. Therefore, we conducted this study to evaluate the effectiveness of C/B ratio in predicting fetal Hb Bart’s disease among fetuses at risk.

Methods
Fetuses at risk of Hb Bart’s disease scheduled for diagnostic cordocentesis at 18 to 22 weeks of pregnancy were prospectively enrolled. All underwent ultrasound for fetal biometry and cardio-STIC acquisition for subsequent off-line analysis. Cardio-STIC volume datasets (VDS) were analyzed for cardiac diameter measurement and C/B ratio was calculated by the authors who did not know the fetal diagnosis. Final diagnosis of Hb Bart’s disease was based on fetal blood Hb typing.

Results
Of 131 pregnancies enrolled to the study, 11 were excluded because of poor quality VDS. The remaining 120 were available for analysis. C/B ratio was significantly higher in the fetuses with Hb Bart’s disease than that in the unaffected ones (53.16% vs 41.68%, P < 0.001). C/B ratio could detect fetuses with Hb Bart’s disease with sensitivity of 91.5% and specificity of 77.6% (AUC ROC 0.929), using a cut-off point of greater than 45%.

Conclusions
Among fetuses at risk, C/B ratio measurement at mid-pregnancy, using cut-off point of 45%, could effectively differentiate fetuses with Hb Bart’s disease from unaffected fetuses.

Published: July 2014

Abstract
The Global System for Mobile communication (GSM) radio network's latest development status and its prominent interference problems were discussed. The limitations of the cellular radio network analysis using the traditional drive test and frequency scanning technology were discussed, which led to the inaccurate interference location and inefficient interference optimization. A new training sequence parallel detection technology base on timeslot sliding window was proposed. The timeslot sliding window mechanism and the training sequence parallel correlative detection algorithms were discussed in detail, and the advantage of these technologies was discussed though comparative analysis. With the successful application cases of the engineering practice in Zhejiang Province of China, the important value of the new technology proposed in this paper in the radio network planning and optimization engineering applications was proved.

AbstractAdvances in biomedical science are leading to upsurge synthesis of nanodelivery systems for drug delivery. The systems were characterized by controlled, targeted and sustained drug delivery ability. Humans are the target of these systems, hence, animals whose systems resembles humans were used to predict outcome.Thus, increasing costs in money and time, plus ethical concerns over animal usage. However, with consideration and planning in experimental conditions,in vitropharmacological studies of the nanodelivery can mimic thein vivosystem. This can function as a simple method to investigate the effect of such materials without endangering animals especially at screening phase.

Abstract
Background
Diabetes is a chronic disease and its control requires essential change in patients' life style. The aim of this study was survey of effects of educational intervention based on PRECEDE Model on self care behaviors and control in patients with type 2 diabetes.

Methods
This was a quasi-experimental study carried out in 78 patients with type 2 diabetes who have referred to Minoodasht clinic of diabetes. The educational program has been designed according to the PRECEDE Model. Prior to perform the educational intervention, the patients filled a questionnaire which was designed according to the structure of PRECEDE Model for type 2 diabetes patients. The diabetes education program was performed on three target groups (patients, their families and Health care personnel). After four weeks, the effects of the educational program have been evaluated through the same questionnaire. The findings were analyzed by SPSS version 16 and p-value less than 0.05 was taken as statistically significant.

Results
The mean age of participants was 49 years, 87.2% were married and 19.2% was illiterate. The rate of income of 44.9% was low. 66% had a family history of diabetes and 64% had been afflicted with diabetes more than 5 years. The Chi-square test showed a significant relationship between formation of a file in diabetes clinic and on-time presence to receive services and participation in the educational classes with the marital status variable. The results also showed that there is a significant relationship between observing food diet and job. The mean scores of knowledge, attitude, practice, reinforcing factors and enabling factors has increased after educational intervention. The Chi-square test shows a significant difference before and after of education intervention in stages of the model.

Conclusion
The obtained results based on PRECEDE Model would support the positive effect of the educational intervention and its major elements (predisposing, enabling and reinforcing factors) on diabetes self-care behaviors.
All capacities modular cost survivable network design problem using genetic algorithm with completely connection encoding
Authors: Binh Huynh Thi Thanh , Ngo Son Hong 
Published: July 2014

AbstractWe study the survivable network design problem (SNDP) for simultaneous unicast and anycast flows in networks where the link cost follows All Capacities Modular Cost (ACMC) model. Given a network modeled by a connected, undirected graph and a set of flow demands, this problem aims at finding a set of connections with a minimized network cost in order to protect the network against any single failure. This paper proposes a new Genetic Algorithm with an efficient encoding to solve the SNDP in networks with ACMC model (A-SNDP). Our encoding scheme is simple and allows large search space. Extensive simulation results on real large topology instances show that the proposed algorithm is much more efficient than the Tabu Search and other conventional Genetic Algorithm in terms of minimizing the network cost.
Resonant-frequency tuning of angular vertical comb-driven microscanner
Authors: Eun Youngkee , Kim Jongbaeg , Lin Liwei 
Published: July 2014

Abstract
The resonant-frequency tuning of a self-aligned angular vertical comb-driven electrostatic microscanner is demonstrated by the electromechanical spring effect. The microscanner is fabricated on a silicon-on-insulator wafer using the plastic deformation of silicon. A tuning electrode is fabricated to be electrically separated from the actuation electrode to tune the resonant frequency by adjusting the applied direct-current voltage bias. The experimentally obtained maximum resonant-frequency shift was 3.2% when the resonant frequency of 3167 Hz is reduced to 3066 Hz when a tuning voltage of 30 V was applied while maintaining the actuation voltage. The method enables facile frequency tuning without any permanent geometrical modification to the microscanner.
That was then this is now … The Canyons – with Paul, Bret, James and Lindsay
Authors: Munt Alex 
Published: July 2014

Abstract
New Hollywood, from the late 1960s to early 1980s, was marked by an innovation in film business (production, marketing, audience) together with an opening up of film form. Today, some 50 years later, film culture is again in flux with new models of funding, production and distribution for the digital age. The impact of these developments on screenwriting is (necessarily) speculative at this stage. The focus of this article is on screenwriter/director Paul Schrader, a jump-cut from Taxi Driver (1976) to The Canyons (2013) – his experiment in ‘post-theatrical cinema’ with novelist/screenwriter Bret Easton Ellis. The film was written for microbudget and crowdfunded on the Kickstarter platform. It assembles the notorious cast of porn star James Deen and celebrity maelstrom Lindsay Lohan. The Canyons rolled out with an aggressive online marketing strategy and innovative ‘day and date’ distribution model with an eye to video on demand. Larry Gross has described the film as belonging to ‘this cultural moment’. In this analysis of The Canyons I ask: What does it mean to conceive, and write, a screenplay for the present, for ‘now’? How does screenplay development and creative collaboration differ in a crowdfunded/microbudget environment? How does the film interact with new forms, and aesthetics, appropriate to this ‘cultural moment’? In the final part of the article I attempt to situate the film within a wider narrative framework via Schrader’s diagnosis of ‘narrative exhaustion’, Douglas Rushkoff’s theory of ‘present shock’ and Ellis’ rumination on the American ‘post-empire’ condition.
Fast and accurate deflectometry with crossed fringes
Authors: Liu Yuankun , Olesch Evelyn , Yang Zheng , Häusler Gerd 
Published: July 2014

Abstract
Phase measuring deflectometry (PMD) acquires the two components of the local surface gradient via a sequence of two orthogonal sinusoidal fringe patterns that have to be displayed and captured separately. We will demonstrate that the sequential process (different fringe directions, phase shifting) can be completely avoided by using a cross fringe pattern. With an optimized Fourier evaluation, high quality data of smooth optical surfaces can be acquired within one single shot. The cross fringe pattern allows for one more improvement of PMD: we will demonstrate a novel phase-shift technique, where a one-dimensional N-phase shift allows for the acquisition of the two orthogonal phases, with only N exposures instead of 2N exposures. Therefore, PMD can be implemented by a one-dimensional translation of the fringe pattern, instead of the common two-dimensional translation, which is quite useful for certain applications.
Changes of wettability of medium density fiberboard (MDF) treated with He-DBD plasma

Published: July 2014

Abstract
The effects of two power levels (50 and 150 W) and five time levels (10, 20, 40, 60 and 120 s) of glow discharge in helium dielectric barrier discharge (He-DBD) has been investigated in the context of surface modification of medium density fiberboard (MDF) panels. He-DBD elevated the surface wettability of MDF panels as assessed by dynamic contact angle (CA) measurements including the determination of surface free energy, droplet volume and spreading contact area of droplets. The chemical changes of the MDF surfaces were also characterized by X-ray photoelectron spectroscopy (XPS). Expectedly, the apparent CA and droplet volume decreased with increasing power and time of glow discharge, mainly at the 150 W power level. The oxygen content of the surfaces, the surface free energy and the spreading contact area increased upon treatment. At higher energy levels the treatment time could be reduced, which is essential for future applications in industrial processes.

313, 334, 352, and 372 K). The values of ε
T were found to decrease with increasing temperature and
could be described by the equation ε
T =− 0.14T + 85.5, where T is the temperature. Oxidation of
Np(V) to Np(VI) in 3 M nitric acid at elevated temperatures
(336, 342, 354, and 362 K) was observed using the optical
glass cell. Oxidation of Np(V) was promoted by increasing the
temperature and proceeded as a pseudo-first order reaction with
respect to Np(V) concentration. The rate equation in the temperature
range of 336–362 K was obtained as follows:
