Published: January 2014

AbstractHigh‐performance two‐unit all‐phosphorescent white devices on a built‐up light extraction substrate that comprised high‐index materials were studied. As a result of suitable optical and electrical design, the device showed an extremely high efficacy of 114 lm/W at 1000 cd/m2. The device also showed 102 lm/W with long lifetime (LT70) of over 10,000 h at 3000 cd/m2. Outstanding external quantum efficiency of almost 50% was also achieved in a flat panel with an emissive area of 25 cm2. Color coordinates of the panel met the Energy Star® criteria of solid‐state lighting with CIE (Commission Internationale de l'Éclairage) 1931 (x, y) = (0.477, 0.423), and the color rendering index was 81.

Objectives/HypothesisPharyngocutaneous fistulae (PCF) are known to occur in nearly one‐third of patients after salvage total laryngectomy (STL). PCF has severe impact on duration of admission and costs and quality of life and can even cause severe complications such as bleeding, infection and death. Many patients need further surgical procedures. The implications for functional outcome and survival are less clear. Several studies have shown that using vascularized tissue from outside the radiation field reduces the risk of PCFs following STL. This review and meta‐analysis aims to identify the evidence base to support this hypothesis.Data SourcesEnglish language literature from 2004 to 2013Review MethodsWe searched the English language literature for articles published on the subject from 2004 to 2013.ResultsAdequate data was available to identify pooled incidence rates from seven articles. The pooled relative risk derived from 591 patients was 0.63 (95% CI: 0.47 to 0.85), indicating that patients who have flap reconstruction/reinforcement reduced their risk of PCF by one‐third.ConclusionThis pooled analysis suggests that there is a clear advantage in using vascularized tissue from outside the radiation field in the laryngectomy defect. While some studies show a clear reduction in PCF rates, others suggest that the fistulae that occur are smaller and rarely need repair. Laryngoscope, 124:1848–1853, 2014

Objectives/HypothesisTo develop and assess the feasibility of a new standardized protocol to guide tracheostomy decannulation.Study DesignDescriptive review of quality improvement project.MethodsA quality improvement project was conducted in the inpatient setting of a tertiary urban academic hospital. Adult patients who had received a tracheostomy and for whom the indication for tracheostomy had resolved were included. A multidisciplinary task force reviewed input from clinicians caring for tracheostomy patients and developed a protocol for screening, capping, and decannulation. The primary outcome measured was successful decannulation.ResultsFifty‐seven patients were screened for a capping trial over a 12‐month period; 54 were capped. Six patients were lost to follow‐up. Fifty patients passed the capping trial, and all 50 were decannulated successfully. When decannulation was pursued in one patient who had twice failed the screening criteria and subsequent capping trials, the patient failed decannulation and ultimately required reintubation for the management of secretions. The screening tool had high sensitivity (90%) and positive predictive value (100%) for successful decannulation. Additionally, the number of reported patient safety concerns decreased from seven in the 6 months preceding implementation of the program to one report in the 6 months after implementation.ConclusionThe new tracheostomy capping and decannulation protocol assisted in predicting both successful and failed decannulation. Although several patients failed certain capping criteria initially, the protocol stipulated modifications of care that enabled successful decannulation. The screening tool had high sensitivity and promoted communication, standardization of practice, and patient safety.Level of Evidence2b. Laryngoscope, 124:1794–1800, 2014

Comparison of sampling strategies and sparsifying transforms to improve compressed sensing diffusion spectrum imaging
Authors: Paquette Michael , Merlet Sylvain , Gilbert Guillaume , Deriche Rachid , Descoteaux Maxime 
Published: January 2014

PurposeDiffusion Spectrum Imaging enables to reconstruct the ensemble average propagator (EAP) at the expense of having to acquire a large number of measurements. Compressive sensing offers an efficient way to decrease the required number of measurements. The purpose of this work is to perform a thorough experimental comparison of three sampling strategies and six sparsifying transforms to show their impact when applied to accelerate compressive sensing‐diffusion spectrum imaging.MethodsWe propose a novel sampling scheme that assures uniform angular and random radial q‐space samples. We also compare and implement six discrete sparse representations of the EAP and thoroughly evaluate them on synthetic and real data using metrics from the full EAP, kurtosis, and orientation distribution function.ResultsThe discrete wavelet transform with Cohen–Daubechies–Feauveau 9/7 wavelets and uniform angular sampling in combination with random radial sampling showed to be better than other tested techniques to accurately reconstruct the EAP and its features.ConclusionIt is important to jointly optimize the sampling scheme and the sparsifying transform to obtain accelerated compressive sensing‐diffusion spectrum imaging. Experiments on synthetic and real human brain data show that one can robustly recover both radial and angular EAP features while undersampling the acquisition to 64 measurements (undersampling factor of 4).

Gradient rotating outer volume excitation (GROOVE): A novel method for single‐shot two‐dimensional outer volume suppression
Authors: Powell Nathaniel J. , Jang Albert , Park Jang‐Yeon , Valette Julien , Garwood Michael , Marjańska Małgorzata 
Published: January 2014

PurposeTo introduce a new outer volume suppression (OVS) technique that uses a single pulse and rotating gradients to accomplish frequency‐swept excitation. This new technique, which is called gradient rotating outer volume excitation (GROOVE), produces a circular or elliptical suppression band rather than suppressing the entire outer volume.MethodsTheoretical and k‐space descriptions of GROOVE are provided. The properties of GROOVE were investigated with simulations, phantom, and human experiments performed using a 4T horizontal bore magnet equipped with a TEM coil.ResultsSimilar suppression performance was obtained in phantom and human brain using GROOVE with circular and elliptical shapes. Simulations indicate that GROOVE requires less SAR and time than traditional OVS schemes, but traditional schemes provide a sharper transition zone and less residual signal.ConclusionGROOVE represents a new way of performing OVS in which spins are excited temporally in space on a trajectory that can be tailored to fit the shape of the suppression region. In addition, GROOVE is capable of suppressing tailored regions of space with more flexibility and in a shorter period of time than conventional methods. GROOVE provides a fast, low SAR alternative to conventional OVS methods in some applications (e.g., scalp suppression). Magn Reson Med, 2014. © 2014 Wiley Periodicals, Inc.

Propagation of Love wave in fiber‐reinforced medium lying over an initially stressed orthotropic half‐space
Authors: Kundu Santimoy , Gupta Shishir , Manna Santanu 
Published: January 2014

SUMMARYIn this paper, the propagation of Love waves in a fiber‐reinforced layered medium lying over an elastic orthotropic half‐space under initial stress has been investigated. We have obtained the velocity equations for Love wave in this media. It is observed that propagation of Love wave is influenced by reinforced parameters and initial stressed parameter. The velocity of Love wave has been computed for three different cases. Our computed equation of Love wave coincides with the standard equation of Love wave for the case of homogeneous layer and homogeneous half‐space (AEH Love, 1911). To study the effect of reinforced and initial stressed parameters, we have computed the numerical values for phase velocity and plotted in several figures. It is observed that the phase velocity decreases with the increases of reinforced parameters and initial stressed parameter. Using MATLAB software, GUI has been developed to generalize the effect of various parameters. Copyright © 2014 John Wiley & Sons, Ltd.
Outcome of indwelling tunneled PleurX® catheter placement in pediatric and young adult patients with malignant effusions
Authors: Adams John , Auger JoAnne , Schiff Deborah 
Published: January 2014

AbstractMalignant effusions may cause significant morbidity and mortality for cancer patients. Indwelling tunneled PleurX® catheter placement for intermittent drainage of malignant effusions has been shown to be efficacious in adults but has not been studied in children. We performed a retrospective review of nine children and young adults who underwent PleurX® catheter placement for the palliation of symptoms associated with malignant effusions. Eight of nine demonstrated symptomatic improvement and seven of nine were discharged from the hospital after catheter placement. No patients experienced catheter‐associated complications. PleurX® catheter placement should be considered for palliation of symptoms due to malignant effusions in pediatric oncology patients.

A meta‐analysis of the association between NQO1 C609T variation and acute myeloid leukemia risk
Authors: Li Cuiping , Liu Yun , Wei Shujiao , Zhou Yang 
Published: January 2014

AbstractQuinone oxidoreductase (NQO1) C609T polymorphisms have been implicated in acute myeloblastic leukemia (AML) risk, but previously published studies are inconsistent and recent meta‐analyses have not been adequate. To derive a more precise estimation of the relationship, a meta‐analysis was performed. Medline, PubMed, Embase, and Web of Science were searched. The quality of studies was evaluated by using the Newcastle–Ottawa Scale (NOS). Crude ORs with 95% CIs were used to assess the strength of association between theNQO1C609T polymorphisms and AML risk. A total of 14 studies including 2,245 cases and 3,310 controls were involved in this meta‐analysis. Overall, significantly elevated AML risk was associated with NQO1 C609T variant genotypes when all studies were pooled into the meta‐analysis (TT vs. CC: OR = 1.44, 95% CI = 1.15–1.81; dominant model: OR = 1.35, 95% CI = 1.09–1.68). In the subgroup analysis by ethnicity, significantly increased risks were found for Asians (OR = 1.47, 95% CI = 1.13–1.93,P = 0.005, I2 = 48.4%,P = 0.071 for heterogeneity). When stratified by studies of adults or children, statistically significantly elevated risks were found among adults (OR = 1.37, 95% CI = 1.06–1.76,P = 0.017, I2 = 42.2%,P = 0.097 for heterogeneity). The accumulated evidence indicates thatNQO1 C609Tseems to confer a risk factor for AML among Asians and adults. Significant between‐study heterogeneity was observed, thus more studies based on larger case‐control population are required to further evaluate the role ofNQO1 C609Tpolymorphism in AML.

Evidence of a minimum in refractive indexes of amorphous GexTe100−x films: Relevance to the development of infrared waveguides
Authors: Vigreux Caroline , Piarristeguy Andrea , Escalier Raphaël , Ménard Stéphane , Barillot Marc , Pradel Annie 
Published: January 2014

Investigation of GexTe100−x amorphous films deposited by thermal co‐evaporation in a large zone of compositions revealed the presence of a minimum in the evolution of the refractive index in the range x ∈ [22;35]. Such a minimum has a great impact on the control of the film refractive index, an undeniable advantage for the manufacture of infrared waveguides. Indeed a similar fluctuation in the film composition in this zone during deposition results in a decrease in refractive index fluctuation by a factor of ∼10 as compared to variation observed in other regions.On the left: planar waveguide formed by a GexTe100−x deposited onto an As2Se3 bulk glass; on the right: output of the m‐lines experiment in the near infrared.

Published: January 2014

ABSTRACTObjectivesTo apply fetal midbrain (MB) and hindbrain (HB) nomograms, developed using three‐dimensional multiplanar sonographic reconstruction (3D‐MPR) in the mid‐sagittal cranial plane, to fetuses with known posterior fossa malformations.MethodsIn this retrospective study we examined sonographic volumes obtained by sagittal acquisition in 43 fetuses diagnosed with posterior fossa abnormalities and evaluated in the mid‐sagittal cranial plane, using 3D‐MPR, the following: MB parameters tectal length (TL) and anteroposterior midbrain diameter (APMD), and HB parameters anteroposterior pons diameter (APPD), superoinferior vermian diameter (SIVD) and anteroposterior vermian diameter (APVD). Fetuses were grouped, according to malformation, into eight categories: cobblestone malformation complex (CMC, n = 3), Chiari‐II malformation (C‐II, n = 7), pontocerebellar hypoplasia (PCH, n = 2), rhombencephalosynapsis (RES, n = 4), Dandy–Walker malformation (n = 8), vermian dysgenesis (VD, n = 7), persistent Blake's pouch cyst (n = 6) and megacisterna magna (n = 6). In each case and for each subgroup, the MB‐HB biometric parameters and their z‐scores were evaluated with reference to our new nomograms.ResultsThe new MB‐HB nomograms were able to identify the brainstem and vermian anomalies and differentiate fetuses with MB‐HB malformations from those with isolated enlarged posterior fossa cerebrospinal fluid spaces. Use of the nomograms enabled detection of an elongated tectum in fetuses with CMC, C‐II and RES, and a flattened pontine belly in cases of CMC, PCH and VD. In the fetuses with VD, the nomograms enabled division into three distinctive groups: (1) those with small SIVD and APVD, (2) those with normal SIVD but small APVD, and (3) those with small SIVD but normal APVD.ConclusionsApplication of our new reference data, that for the first time include the MB, enables accurate diagnosis of brain malformations affecting the MB and HB and makes possible novel characterization of previously described features of posterior fossa anomalies.

Assessing the risks posed by mixtures of chemicals in freshwater environments: case study of Lake Geneva, Switzerland
Authors: Gregorio Vincent , Chèvre Nathalie 
Published: January 2014

Aquatic organisms are typically exposed simultaneously to several organic compounds released from human activities like agriculture, industries, or simply from people living in cities. The ecological risk assessment of mixtures of such compounds has therefore to be addressed by scientists. The aims of this paper are (1) to describe the current mixture risk assessment procedures, (2) to apply such approach to a specific case study, Lake Geneva and the River Rhône in Switzerland, and (3) to discuss the outcomes of such an application. Two models, called concentration addition and independent action, are recognized to be robust enough to predict the mixture effect of substances on a given species. They are classically used also to assess the risk of mixtures for the ecosystem, but their use is often limited by the lack of available ecotoxicity data. Adopting a first level assessment, we describe the evolution of the mixture risk for several years of Lake Geneva, and for 2010 for the River Rhône. These first assessments allow identification of the most problematic substances demanding risk reduction measures. Furthermore, again for the two cases studies, we show that the risk levels associated with mixtures of compounds can rapidly exceed critical aquatic thresholds, and therefore, it is the sum of the substances that is problematic, which is more challenging in term of risk management. Further analysis of effects in compound mixtures as well as a better characterization of the overall ecological risk are necessary for the thousands substances co‐occuring at very low concentrations.This article is categorized under:Science of Water > Water Quality
Development and validation of a new joint system for sectional blades
Authors: Saenz E. , Nuin I. , Montejo R. , Sanz J. 
Published: January 2014

AbstractThe development and validation of a new joint system for sectional blades is presented in this paper. The system is a bolted connection located in the blade spar cap, and its geometry accommodates a higher number of bolts than any other conventional solution requiring inserts. This results in higher transmitted loads per spar cap width.The modular concept of the system is composed of cell units that can be easily integrated into the design and manufacturing of different blade architectures and used in blades of various lengths by selecting the appropriate number of cell units.The design of the system was performed using analytical and finite element analyses. The analyses were validated using risk reduction mechanical tests, which resulted in an optimized joint system. The loads to be transmitted by the joint system were calculated according to IEC61400‐1 using the GH‐Bladed Version 3.80 on a 5 MW onshore class II‐A wind turbine with a tower height of 120 m and a 61.5 m blade with double spar webs. The joint system was successfully tested in a full‐scale mechanical test for its validation under Germanischer Lloyd guidelines and supervision. Copyright © 2014 John Wiley & Sons, Ltd.

Abstract:
Integrated geoelectric and geochemical investigation were carried out in the Canning and adjoining areas to assess the prevailing groundwater conditions and chemical quality of groundwater. Geologically, the area is constituted of alluvial sediments of Quaternary age. Vertical electrical soundings (VES) in the area of investigation mostly show six layers consisting of top soil, saline water, clay layer, brackish water, clay layer and fresh-water bearing zone of appreciable thicknesses at depths of 137 to 182 meter at six locations and from 370 to 430 meter for other two locations under confined conditions. The result of VES studies significantly correspond with the borehole litholog and well log data. A litho-resistivity relationship is established for this area of investigation A Fence diagram is constructed to show the spatial variation of the sub-surface lithology and hydrological characteristics. Chemically the ground water is fresh and mixed cation and anion type as revealed from Piper-Trilinear diagram with TDS ranging from 699 to 1547 mg/l. The geochemical parameters like Total hardness (TH), Sodium absorption ratio (SAR), Soluble sodium percentage (SSP), Percentage of sodium (PS), Kelley’s ratio (KR), Residual sodium carbonate (RSC), Corrosivity ratio (CR), Gibbs ratios (GR), Chloro alkaline indices (CAI), Sea water contamination (SWC) are also calculated for examining the quality of groundwater in the area. The depth of occurrences of freshwater bearing ground water zones for drinking and irrigation purposes are occurring at depths from 137 meter to 430 meter in this area.
Petrography and Mineral Chemistry of Alkaline–Carbonatite Complex in Singhbhum Crustal Province, Purulia Region, Eastern India
Authors: Basu S. K. , Bhattacharyya T. 
Published: January 2014

Abstract:
The variant rock types of an Alkaline–Carbonatite Complex (ACC) comprising alkali pyroxenite, nepheline syenite, phoscorite, carbonatite, syenitic fenite and glimmerite along with REE and Nb–mineralization are found at different centres along WNW-ESE trending South Purulia Shear Zone (SPSZ) in parts of Singhbhum Crustal Province. The ACC occurs as intrusions within the Mesoproterozoic Singhbhum Group of rocks. Alkali pyroxenite comprises of aegirine augite, magnesiotaramite, magnesiokatophorite as major constituents. Pyrochlore and eucolite are ubiquitous in nepheline syenite. Phoscorite contains fluorapatite, dahllite, collophane, magnetite, hematite, goethite, phlogopite, calcite, sphene, monazite, pyrochlore, chlorite and quartz. Coarse fluorapatite shows overgrowth of secondary apatite (dahllite). Secondary apatite is derived from primary fluorapatite by solution and reprecipitation. The primary fluorapatite released REE to crystallize monazite grains girdling around primary apatite. Carbonatite is composed dominantly of Srcalcite along with dolomite, tetraferriphlogopite, phlogopitic biotite, aegirine augite, richterite, fluorapatite, altered magnetite, sphene and monazite. The minerals comprising of the carbonatite indicate middle stage of carbonatite development. Fenite is mineralogically syenite. Glimmerite contains 50–60% tetraferriphlogopite. An alkali trend in the evolution of amphiboles (magnesiotaramite–magnesiokatophorite–richterite) and chinopyroxenes (aegirine augite, aegirine) during the crystallization of the suite of rocks is noted. Monazite is the source of REE in phoscorite and carbonatite. Fluorapatite has low contents of REE, PbO, ThO2 and UO2. Pyrochlore reflects Nb-mineralization in nepheline syenite and it is enriched in Na2O, CaO, TiO2, PbO and UO2. Pyrochlore containing UO2 (6.605%) and PbO (0.914%) in nepheline syenite has been chemically dated at 948 ± 24 Ma by EPMA.
