Published: January 2016

Purpose To evaluate the extent of normal variation in implantable port devices between supine fluoroscopy and upright chest x-ray in relation to body mass index (BMI) based on three different measurement methods. Methods Retrospectively, 80 patients with implanted central venous access port systems from 2012-01-01 until 2013-12-31 were analyzed. Three parameters (two quantitative and one semi-quantitative) were determined to assess port positions: projection of port capsule to anterior ribs (PCP) and intercostal spaces, ratio of extra- and intravascular catheter portions (EX/IV), normalized distance of catheter tip to carina (nCTCD). Changes were analyzed for males and females and normal-weight and overweight patients using analysis of variance with Bonferroni-corrected pairwise comparison. Results PCP revealed significantly greater changes in chest x-rays in overweight women than in the other groups (p<0.001, F-test). EX/IV showed a significantly higher increase in overweight women than normal-weight women and men and overweight men (p<0.001). nCTCD showed a significantly greater increase in overweight women than overweight men (p = 0.0130). There were no significant differences between the other groups. Inter- and intra-observer reproducibility was high (Cronbach alpha of 0.923-1.0) and best for EX/IV. Conclusions Central venous port systems show wide normal variations in the projection of catheter tip and port capsule. In overweight women apparent catheter migration is significantly greater compared with normal-weight women and with men. The measurement of EX/IV and PCP are straightforward methods, quick to perform, and show higher reproducibility than measurement of catheter tip-to-carina distance.

Este	estudio pretende identificar los factores que influyen en	las percepciones de los profesores sobre los beneficios de	los medios educativos digitales para la enseñanza y el	aprendizaje. Varios estudios relevantes han	indicado que cuando los profesores creen que los medios	educativos digitales son valiosos para la enseñanza y el	aprendizaje, son más propensos a incorporarlos en su	práctica docente. Se han considerado tres conjuntos de	factores como variables independientes: las características	de la escuela y del profesor, las características	tecnológicas de la escuela, y las características	tecnológicas del profesor. Se recogieron datos de 702	profesores de unas 356 escuelas de educación primaria y	secundaria en España con un cuestionario. Mediante análisis	de correlación múltiple y de regresión jerárquica examinamos	la relación entre las variables independientes y las	percepciones de los profesores. Los resultados muestran una	fuerte relación entre estas percepciones y las	características tecnológicas del profesor. Los factores más	predictivos son el área de enseñanza, la alfabetización	digital, la formación en tecnología educativa y la	frecuencia de acceso a Internet, dentro y fuera de la	escuela. Por último, sugerimos que la integración de los	medios educativos digitales en el aula es un objetivo totalmente	interrelacionados con las finalidades instruccionales de los	profesores
La evaluación auténtica: el uso de la evaluación para ayudar a los estudiantes a aprende
Authors: Brown Sally 
Published: January 2016

La	evaluación auténtica ofrece a los estudiantes oportunidades	para aprender a través del propio proceso de evaluación ,	cuando las tareas se eligen por su relevancia tanto para el	programa de aprendizaje como para las orientaciones vitales	que ofrecen a los graduados, de cara a su empleabilidad,	investigación y desarrollo personal. Cuando la evaluación	está diseñada para articularse claramente con los resultados	de aprendizaje previstos, puede producir beneficios en	términos de fomentar y profundizar en la participación de	los estudiantes al tiempo que ayuda a los estudiantes a	avanzar en el desarrollo de sus habilidades y en el	conocimiento de la materia. Si bien la creación y la	gestión de las tareas de evaluación auténticas pueden	requerir mucho tiempo y recursos, se argumenta aquí que los	beneficios en términos de mejora de aprendizaje son muy	superiores a esos factores. El artículo concluye con un	manifiesto proponiendo algunas condiciones previas para la	evaluación eficaz y auténtica.

Abstract
We propose a two-step SU8/poly(vinyl alcohol) (PVA) lift-off photolithography scheme for fabricating top-contact pentacene-based organic thin-film transistors (OTFTs) with small channels. The bilayer of PVA and SU8 will not damage the pentacene channel layer in the lift-off photolithography process used in forming the patterned pentacene channel layer and source/drain metal electrodes. We demonstrate a device that not only obtains a 5 µm short channel length for source/drain metal-electrode patterning but also avoids fringe current resulting from pentacene channel layer patterning. The field-effect mobility and threshold voltage of the pentacene-based OTFTs were changed from 0.29 to 0.12 cm2 V−1 s−1 and from −5.74 to −3.19 V by varying the channel length from 50 to 5 µm, respectively. The proposed scheme is a good candidate for use in the design and fabrication of high-performance short-channel organic electronics.

Abstract
Transparent p-type NiO films were prepared by reactive sputtering using the facing-target system under Ar-diluted O2 gas at T
sub of 30 and 200 °C. The increasing intensity of dominant X-ray diffraction (XRD) peaks indicates improvements in the crystallinity of NiO films upon Cu doping. In spite of the crystallographic and optical changes after Cu-doping, the electrical properties of Cu-doped NiO films were slightly improved. Upon Ag-doping at 30 °C under low O2 concentration, on the other hand, the intensity of the dominant (111) XRD peaks was suppressed and p-type conductivity increased from ∼10−3 to ∼10−1 S cm−1. Finally, our Ag-doped NiO films were applied as the back contact of CdTe solar cells. CdTe solar cells with a glass/ITO/CdS/CdTe/NiO structure exhibited an efficiency of 6.4%, suggesting the high potential of using p-type NiO for the back-contact film in thin-film solar cells.

First spaceborne observation of sea surface height using GPS‐Reflectometry
Authors: Clarizia Maria Paola , Ruf Christopher , Cipollini Paolo , Zuffada Cinzia 
Published: January 2016

AbstractAn analysis of spaceborne Global Positioning System reflectometry (GPS‐R) data from the TechDemoSat‐1 (TDS‐1) satellite is carried out to image the ocean sea surface height (SSH). An SSH estimation algorithm is applied to GPS‐R delay waveforms over two regions in the South Atlantic and the North Pacific. Estimates made from TDS‐1 overpasses during a 6 month period are aggregated to produce SSH maps of the two regions. The maps generally agree with the global DTU10 mean sea surface height. The GPS‐R instrument is designed to make bistatic measurements of radar cross section for ocean wind observations, and its altimetric performance is not optimized. The differences observed between measured and DTU10 SSH can be attributed to limitations with the GPS‐R instrument and the lack of precision orbit determination by the TDS‐1 platform. These results represent the first observations of SSH by a spaceborne GPS‐R instrument.
Improving back projection imaging with a novel physics‐based aftershock calibration approach: A case study of the 2015 Gorkha earthquake
Authors: Meng Lingsen , Zhang Ailin , Yagi Yuji 
Published: January 2016

AbstractThe 2015 Mw 7.8 Nepal‐Gorkha earthquake with casualties of over 9000 people was the most devastating disaster to strike Nepal since the 1934 Nepal‐Bihar earthquake. Its rupture process was imaged by teleseismic back projections (BP) of seismograms recorded by three, large regional networks in Australia, North America, and Europe. The source images of all three arrays reveal a unilateral eastward rupture; however, the propagation directions and speeds differ significantly between the arrays. To understand the spatial uncertainties of the BP analyses, we analyze four moderate size aftershocks recorded by all three arrays exactly as had been conducted for the main shock. The apparent source locations inferred from BPs are systematically biased from the catalog locations, as a result of a slowness error caused by three‐dimensional Earth structures. We introduce a physics‐based slowness correction that successfully mitigates the source location discrepancies among the arrays. Our calibrated BPs are found to be mutually consistent and reveal a unilateral rupture propagating eastward at a speed of 2.7 km/s, localized in a relatively narrow and deep swath along the downdip edge of the locked Himalayan thrust zone. We find that the 2015 Gorkha earthquake was a localized rupture that failed to break the entire Himalayan décollement to the surface, which can be regarded as an intermediate event during the interseismic period of larger Himalayan ruptures that break the whole seismogenic zone width. Thus, our physics‐based slowness correction is an important technical improvement of BP, mitigating spatial uncertainties and improving the robustness of single and multiarray studies.
Impact of remotely sensed albedo and vegetation fraction on simulation of urban climate in WRF‐urban canopy model: A case study of the urban heat island in Los Angeles
Authors: Vahmani P. , Ban‐Weiss G. A. 
Published: January 2016

AbstractModeling the climate of urban areas is of interest for studying urban heat islands (UHIs). Reliable assessment of the primary causes of UHIs and the efficacy of various heat mitigation strategies requires accurate prediction of urban temperatures and realistic representation of land surface physical characteristics in models. In this study, we expand the capabilities of the Weather Research and Forecasting (WRF) model by implementing high‐resolution, real‐time satellite observations of green vegetation fraction (GVF) and albedo. Satellite‐based GVF and albedo replace constant values that are assumed for urban pixels in the default version of WRF. Simulations of urban meteorology in Los Angeles using the improved model show marked improvements relative to the default model. The largest improvements are for nocturnal air temperatures, with a reduction in root‐mean‐square deviation between simulations and observations from 3.8 to 1.9°C. Utilizing the improved model, we quantify relationships between surface and 2 m air temperatures versus urban fraction, GVF, albedo, distance from the ocean, and elevation. Distance from the ocean is found to be the main contributor to variations in temperatures around Los Angeles. After conditionally sampling pixels to minimize the influence of distance from the ocean and elevation, we find that variations in GVF and urban fraction are responsible for up to 58 and 27% of the variance in temperatures. The satellite‐supported meteorological modeling framework reported here can be used for studying UHIs in other cities and can serve as a foundation for testing the efficacy of various heat mitigation strategies.
Water vapor‐weighted mean temperature and its impact on the determination of precipitable water vapor and its linear trend

Published: January 2016

AbstractWater vapor‐weighted mean temperature, Tm, is a vital parameter for retrieving precipitable water vapor (PWV) from the zenith wet delay (ZWD) of Global Navigation Satellite Systems (GNSS) signal propagation. In this study, the Tm at 368 GNSS stations for 2000–2012 were calculated using three methods: (1) temperature and humidity profiles from ERA‐Interim, (2) the Bevis Tm–Ts relationship, and (3) the Global Pressure and Temperature 2 wet model. Tm derived from the first method was used as a reference to assess the errors of the other two methods. Comparisons show that the relative errors of the Tm derived from these two methods are in the range of 1–3% across more than 95% of all the stations. The PWVs were calculated using the aforementioned three types of Tm and the GNSS‐derived ZWD at 107 stations. Again, the PWVs calculated using Tm from the first method were used as the reference of the other two PWVs. The root‐mean‐square errors of these two PWVs are both in the range of 0.1–0.7 mm. The second method is recommended in real‐time applications, since its performance is slightly better than the third method. In addition, the linear trends of the PWV time series from the first method were also used as the reference to evaluate the trends from the other two methods. Results show that 13% and 23% of the PWV trends from the respective second and third methods have a relative error of larger than 10%. For climate change studies, the first method, if available, is always recommended.

Published: January 2016

AbstractThe synthesis, structure, and energetic materials properties of a series of aromatic peroxy acid compounds are described. Benzene‐1,3,5‐tris(carboperoxoic) acid is a highly sensitive primary energetic material, with impact and friction sensitivities similar to those of triacetone triperoxide. By contrast, benzene‐1,4‐bis(carboperoxoic) acid, 4‐nitrobenzoperoxoic acid, and 3,5‐dinitrobenzoperoxoic acid are much less sensitive, with impact and friction sensitivities close to those of the secondary energetic material 2,4,6‐trinitrotoluene. Additionally, the calculated detonation velocities of 3,5‐dinitrobenzoperoxoic acid and 2,4,6‐trinitrobenzoperoxoic acid exceed that of 2,4,6‐trinitrotoluene. The solid‐state structure of 3,5‐dinitrobenzoperoxoic acid contains intermolecular O‐H⋅⋅⋅O hydrogen bonds and numerous N⋅⋅⋅O, C⋅⋅⋅O, and O⋅⋅⋅O close contacts. These attractive lattice interactions may account for the less sensitive nature of 3,5‐dinitrobenzoperoxoic acid.
K2Au(IO3)5 and β‐KAu(IO3)4: Polar Materials with Strong SHG Responses Originating from Synergistic Effect of AuO4 and IO3 Units

Published: January 2016

AbstractTwo new polar potassium gold iodates, namely, K2Au(IO3)5 (Cmc21) and β‐KAu(IO3)4 (C2), have been synthesized and structurally characterized. Both compounds feature zero‐dimensional polar [Au(IO3)4]− units composed of an AuO4 square‐planar unit coordinated by four IO3− ions in a monodentate fashion. In β‐KAu(IO3)4, isolated [Au(IO3)4]− ions are separated by K+ ions, whereas in K2Au(IO3)5, isolated [Au(IO3)4]− ions and non‐coordinated IO3− units are separated by K+ ions. Both compounds are thermally stable up to 400 °C and exhibit high transmittance in the NIR region (λ=800–2500 nm) with measured optical band gaps of 2.65 eV for K2Au(IO3)5 and 2.75 eV for β‐KAu(IO3)4. Powder second‐harmonic generation measurements by using λ=2.05 μm laser radiation indicate that K2Au(IO3)5 and β‐KAu(IO3)4 are both phase‐matchable materials with strong SHG responses of approximately 1.0 and 1.3 times that of KTiOPO4, respectively. Theoretical calculations based on DFT methods confirm that such strong SHG responses originate from a synergistic effect of the AuO4 and IO3 units.

Published: January 2016

AbstractA new and flexible methodology catalyzed by bifunctional chiral thioureas has been developed to react β‐nitro oxindoles 1 with aldehydes. This approach allowed us to achieve the first enantioselective organocatalytic synthesis of 3‐spiro‐α‐alkylidene‐γ‐butyrolactone oxindoles 3. We examined the scope of the two starting materials and, varying the structure of the β‐nitro oxindole 1, intriguing new products, derived from unexpected transformations, have been stereoselectively obtained. The aim of this study was to merge two potentially bioactive structural motifs: the spirooxindole substructure and the α‐alkylidene‐γ‐butyrolactone moiety. A preliminary NMR study on the ability to reversibly trap 2‐aminoethanethiol gave us promising results.
Does the Sign of the Cu–Gd Magnetic Interaction Depend on the Number of Atoms in the Bridge?

Published: January 2016

AbstractSeveral theoretical investigations with CASSCF methods confirm that the magnetic behavior of Cu–Gd complexes can only be reproduced if the 5d Gd orbitals are included in the active space. These orbitals, expected to be unoccupied, do present a low spin density, which is mainly due to a spin polarization effect. This theory is strengthened by the experimental results reported herein. We demonstrate that Cu–Gd complexes characterized by Cu–Gd interactions through single‐oxygen and three‐atom bridges consisting of oxygen, carbon, and nitrogen atoms, present weak ferromagnetic exchange interactions, whereas complexes with bridges made of two atoms, such as the nitrogen–oxygen oximato bridge, are subject to weak antiferromagnetic exchange interactions. Therefore, a bridge with an odd number of atoms induces a weak ferromagnetic exchange interaction, whereas a bridge with an even number of atoms supports a weak antiferromagnetic exchange interaction, as observed in pure organic compounds and also, as in this case, in metal–organic compounds with an active spin polarization effect.
