Abstract. On 9 September 2014, an intensive drifter deployment was carried out in the Strait of Gibraltar. In the frame of the MEDESS-4MS Project (EU MED Program), the MEDESS-GIB experiment consisted of the deployment of 35 satellite tracked drifters, mostly of CODE-type, equipped with temperature sensor sampling at a rate of 30 min. Drifters were distributed along and on both sides of the Strait of Gibraltar. The MEDESS-GIB deployment plan was designed as to ensure quasi-synoptic spatial coverage. To this end, four boats covering an area of about 680 NM2 in 6 h were coordinated. As far as these authors know, this experiment is the most important exercise in the area in terms of number of drifters released. Collected satellite-tracked data along drifter trajectories have been quality controlled and processed to build the presented MEDESS-GIB database. This paper reports the MEDESS-GIB data set that comprises drifter trajectories, derived surface currents and in situ SST measurements collected along the buoys tracks. This series of data is available through the PANGAEA (Data Publisher for Earth and Environmental Science) repository, with the following doi:10.1594/PANGAEA.853701. Likewise, the MEDESS-GIB data will be incorporated as part of the Copernicus Marine historical products. The MEDESS-GIB data set provides a complete Lagrangian view of the surface inflow of Atlantic waters through the Strait of Gibraltar and thus, very useful data for further studies on the surface circulation patterns in the Alboran Sea, and their links with one of the most energetic Mediterranean Sea flows: the Algerian Current.

Published: March 2016

<p>The present study is an attempt to find out the availability of scientific competencies among kindergarten female teachers for identifying children with special needs in Najran and to identify the correlation between the scientific competencies to identify children with special needs and the attitude towards them. The variables utilized in this study are (specialization, years of experience, and number of courses). The study sample consists of (150) kindergarten teachers in Najran for the academic year (2014/2015). For achieving the purposes of the study, the two authors utilized a questionnaire to measure the scientific competencies, which comprised (43) items and another questionnaire to measure the attitude towards children with special needs. The study resulted that the kindergarten teachers enjoy scientific competencies related to the skill of identifying the special-needs child and the skill of dealing with that child. There is also a positive relationship between the scores of the sample of the scientific competencies for the special-needs child and their scores on the scale of the attitude towards the child, as well as there are statistical differences for the scales of competencies and attitudes towards the special-needs child in favor of the specialization of Kindergarten and those of medium work experience (6-10) years. <strong></strong></p>

Published: March 2016

Objectives The purpose of this study was to study the initial fixation and migration pattern of a monoblock acetabular component used for a metal on metal hip resurfacing using Einzel Bild Roentgen Analyse (EBRA). Methods 99 patients with a mean age of 49.6 years (range 28.5-66.3 years) of whom 14 were bilateral underwent a hip resurfacing (Conserve Plus®, MicroPort, Memphis, TN) for a total of 113 resurfacings. Acetabular component orientation was noted with 35 of the 113 components (31.0%) having a lucency >2 mm on the immediate postoperative radiograph. Results The mean follow-up for our cohort of 113 hips is 50 months (2-79 months). When examining the 2-year migration mark, 37 of the 113 hips exceeded the threshold of 0.5 mm/year with a median total migration of 1.40 mm (range 1.02-4.24). 6 resurfacings underwent revision surgery for aseptic loosening of the acetabular component at a mean time of 43.6 months. Presence of initial lucency (OR 2.29, p = 0.05) was the only significant predictor of migration over threshold at 2-years. Those that had migrated over the threshold (1.0 mm) at 2 years were at significantly greater risk of continued migration at 4 years. Conclusions The migration pattern of this component raises concerns about long term performance, with postoperative lucencies representing a significant factor for future migration.

Published: March 2016

Purpose To compare the functional outcomes of patients undergoing arthroscopic surgery for the treatment of femoroacetabular impingement (FAI) performed with either the classic or the outside-in access to the hip. Methods Data regarding patients arthroscopically treated for FAI from January 2009 to June 2013 were retrospectively reviewed and compared regarding the type of access. Results 101 hips (91 patients) with a minimum of 12 months follow-up (mean 22 months, range 12-40 months) were included. Classic access was used in 48 cases while outside-in access was performed in 53 cases. Mean age was 37 years (range 15.7-59.6 years). Both groups were comparable with respect to preoperative characteristics. Mean operating time was 162 minutes for the outside-in group and 172 minutes for the classic access group. Complications between both groups showed no statistically significant differences but for the presence of heterotopic calcifications, which was more frequently observed regarding the outside-in access. Outcomes measured by the modified Harris Hip Score showed no overall differences regarding both types of access, except for patients under 35 years old, where there was a statistically significant increase in excellent and good outcomes with the use of the classic access in comparison to the outside-in technique. Postoperative hip motion was also significantly higher in the classic access group. Conclusions No differences have been found in outcomes regardless the access used. Classic access seems to offer a higher postoperative range of motion and lower risk of heterotopic ossifications.

Published: March 2016

Purpose The main aim of our study is to report the medium-term survivorship of Birmingham Hip Resurfacing (BHR) cup and a large modular metal head (MMT) on an uncemented Freeman femoral stem. No results have been reported till date with these implants combinations. Methods A total of 205 metal-on-metal total hip replacements (MoM THRs) were performed on 190 patients from October 2002 to November 2004. Prior to the Medicines and Healthcare Products Regulatory Agency (MHRA) guidelines, the patients were followed up at 3, 6 and 12 months postoperatively and annually thereafter. Following the MHRA alert in 2010, the patients were followed-up as per the MHRA guidelines. All statistical analyses were conducted using Stata 13. Results At a mean follow-up of 10.5 years, a total of 42 out of 205 hips were revised for reasons related to ALTR. The failure rates increased significantly over time (7% at 6 years and 29% at 10-year follow-up). The analysis showed no statistically significant association to age, gender, side, BMI or component size or position (p<0.05). Blood metal ions showed a poor discriminant ability to separate failed from well-functioning MoM hip replacements. Conclusions Large head MoM BHR on an uncemented stem has extremely high failure rate. The authors do not recommend the use of large head MoM articulation in total hip arthroplasty in the wake of this report and similar findings across the world. Continued surveillance of these implants is required as the failure rates increase with time.

Published: March 2016

Purpose To evaluate the potential risk factors of the development of femoral head osteonecrosis after healed intertrochanteric fractures. Methods We retrospectively reviewed all patients who were operated upon with closed reduction and internal fixation for intertrochanteric fractures by our medical group from December 1993 to December 2012. Patients with healed fractures were identified. Age, gender, comorbidities favouring osteonecrosis, causes of injuries, fracture patterns, the location of the primary fracture line, time from injury to surgery, fixation methods, and the development of femur head osteonecrosis of these patients were summarised. Univariate and multivariate logistic regression analysis were performed to evaluate the correlation between potential risk factors and the development of femoral head osteonecrosis. Results A total of 916 patients with healed intertrochanteric fractures were identified. Femoral head osteonecrosis was found in 8 cases (0.87%). According to the results of univariate logistic regression, a more proximal fracture line, fixation with dynamic hip screws and age were found to be statistically significant factors. The results of multivariate logistic regression analysis indicated that the statistically significant predictors of femoral head osteonecrosis were younger age (odds ratio [OR] = 17.103; 95% confidence interval [CI], 1.988-147.111), a more proximal fracture line (OR = 31.439; 95% CI, 3.700-267.119) and applying dynamic hip screw as the internal fixation (OR = 11.114; 95% CI, 2.064-59.854). Conclusions Regular follow-up is commended in young patients with a proximal fracture line who underwent closed reduction and internal fixation with dynamic hip screw, even though the bone had healed.
High/Positive Expression of 5-Fluorouracil Metabolic Enzymes Predicts Better Response to S-1 in Patients with Gastric Cancer: A Meta-Analysis

Published: March 2016

Purpose To provide an assessment by meta-analysis of the relationship between the expression variations of 5-fluorouracil metabolic enzymes and clinical outcomes in patients with gastric cancer treated with S-1. Method Databases were searched electronically from inception to April 19th, 2015. Studies in gastric cancer patients treated with S-1 investigating the expression variations of 5-fluorouracil metabolic enzymes were included after having been identified systematically. Pooled odds ratios (OR) for the objective response rate (ORR) and median survival ratio were calculated using the Review Manager 5.3 and Stata 12.0 software separately. Results A total of 555 patients in 10 studies met our inclusion criteria. There was a significant difference in ORR between patients with high/+ and low/- expression of orotate phosphoribosyl transferase (OPRT) (OR = 8.06; 95% CI, 4.06-16.02; p<0.001) and dihydropyrimidine dehydrogenase (DPD) (OR = 1.95; 95% CI, 1.21-3.13; p = 0.006). There was no significant difference in ORR between different expression levels of thymidylate synthase (TS) and thymidine phosphorylase (TP). Although patients with low/- TS expression, low/- TP expression and high/+ DPD expression showed a trend towards longer survival, no statistical significance was found. The median OS was significantly longer in patients with high/+ expression of OPRT (p = 0.076). Conclusions OPRT and DPD expression can be treated as a potential predictive biomarker for S-1 response in gastric cancer patients. Further investigation is warranted.
Are Early Cannulation Arteriovenous Grafts (ecAVG) a Viable Alternative to Tunnelled Central venous Catheters (TCVCs)? An Observational “Virtual Study” and Budget Impact Analysis

Published: March 2016

Background Early cannulation arteriovenous grafts (ecAVGs) are advocated as an alternative to tunnelled central venous catheters (TCVCs). A real-time observational “virtual study” and budget impact model was performed to evaluate a strategy of ecAVG as a replacement to TCVC as a bridge to definitive access creation. Methodology Data on complications and access-related bed days was collected prospectively for all TCVCs inserted over a six-month period (n = 101). The feasibility and acceptability of an alternative strategy (ecAVGs) was also evaluated. A budget impact model comparing the two strategies was performed. Autologous access in the form of native fistula was the goal wherever possible. Results We found 34.7% (n = 35) of TCVCs developed significant complications (including 17 culture-proven bacteraemia and one death from line sepsis). Patients spent an average of 11.9 days/patient/year in hospital as a result of access-related complications. The wait for TCVC insertion delayed discharge in 35 patients (median: 6 days). The ecAVGs were a practical and acceptable alternative to TCVCs in over 80% of patients. Over a 6-month period, total treatment costs per patient wereGBP5882 in the TCVC strategy and GBP4954 in the ecAVG strategy, delivering potential savings of GBP927 per patient. The ecAVGs had higher procedure and re-intervention costs (GBP3014 vs. GBP1836); however, these were offset by significant reductions in septicaemia treatment costs (GBP1322 vs. GBP2176) and in-patient waiting time bed costs (GBP619 vs. GBP1870). Conclusions Adopting ecAVGs as an alternative to TCVCs in patients requiring immediate access for haemodialysis may provide better individual patient care and deliver cost savings to the hospital.

The Influence of Weather Conditions on Rates of Return of Polish Equity Indices
Authors: Borowski Krzysztof 
Published: March 2016

<p>The influence of the weather on human behavior have been featured in many, not only scientific publications. This paper tests the hypothesis that the one-session average rates of return of equity indices (WIG, WIG20, mWIG40 and sWIG80) calculated for the different weather conditions differ in two populations. The atmospheric conditions taken into consideration in this paper are as follows: maximum and minimum daily temperature, sunny hours, rainfall, maximum and average wind velocity, atmospheric pressure, snow depth, sun energy ultraviolet radiation index. In the analyzed period, the impact on the daily rates of return was observed in the case of the following weather conditions: maximum daily temperature, sunny hours, rainfall, maximum wind velocity and atmospheric pressure. The other analyzed weather conditions such as average wind velocity, minimum daily temperature, snow depth, sun energy ultraviolet radiation index, turned out to be irrelevant. Thus, the influence of some weather condition on registered rates of return on the Polish equity markets has been proved.</p>
Design and characterization of MEMS optical devices using slot-ring resonator for low-voltage operation
Authors: Amemiya Yoshiteru , Noda Kazuki , Sennichi Takuma , Yokoyama Shin 
Published: March 2016

Abstract
To realize MEMS optical devices with low-voltage operation of less than 1 V, we have proposed a slot-ring resonator with a beam structure. The performance of the proposed device is investigated. From the simulation, a more than 10 dB extinction ratio is estimated at a low voltage of 0.5 V, when the slot waveguide width is 250 nm and the slot width is 50 nm. We succeeded in the fabrication of the proposed device structure, and improvement of the quality factor (from 6400 to 14000) is achieved by changing the lithography process. The modulating operation is confirmed but the extinction ratio is lower than the simulated value. There are several considerable reasons for this low extinction ratio, such as non-optimal carrier concentration in slot waveguides and nonparallel arrangement of slot waveguides and so on. Optimizing the fabrication processes will solve this, and the expected high performance will be achieved.

Abstract
To enable chronic and stable neural recording, we have been developing an implantable multichannel neural recording system with impedance analysis functions. One of the important things for high-quality neural signal recording is to maintain well interfaces between recording electrodes and tissues. We have proposed an impedance analysis circuit with a very small circuit area, which is implemented in a multichannel neural recording and stimulating system. In this paper, we focused on the design of an impedance analysis circuit configuration and the evaluation of a minimal voltage measurement unit. The proposed circuit has a very small circuit area of 0.23 mm2 designed with 0.18 µm CMOS technology and can measure interface impedances between recording electrodes and tissues in ultrawide ranges from 100 Ω to 10 MΩ. In addition, we also successfully acquired interface impedances using the proposed circuit in agarose gel experiments.

Published: March 2016

Abstract
A transient response of nuclear spins in GaAs to a change in a magnetic field was analyzed based on the time evolution of nuclear spin temperature. Simulation results well reproduced our experimental results on transient oblique Hanle signals observed in an all-electrical spin injection device, enabling a quantitative understanding of nuclear spin dynamics in the presence of a hyperfine interaction between nuclei and polarized electrons. Analysis regarding the time evolution of nuclear spin temperature revealed that the hysteretic nature of a nuclear field with respect to the sweep direction of an external field was caused by the delay of time response of nuclear spin temperature to a change in the magnetic field. This analysis provides a deep understanding of nuclear spin dynamics in semiconductors.
Fully coupled atmospheric‐hydrological modeling at regional and long‐term scales: Development, application, and analysis of WRF‐HMS
Authors: Wagner Sven , Fersch Benjamin , Yuan Fei , Yu Zhongbo , Kunstmann Harald 
Published: March 2016

AbstractA closed description of the regional water balance requires hydro‐meteorological modeling systems which represent the atmosphere, land surface, and subsurface. We developed such a mesoscale modeling system, extending the atmospheric model WRF with the distributed hydrological model HMS in a fully coupled way. It includes explicit lateral groundwater and land surface flow parameterization schemes and two‐way groundwater‐unsaturated zone interaction by replacing the free drainage bottom boundary of WRF's Noah‐LSM with a Fixed‐head or Darcy‐flux boundary condition. The system is exemplarily applied for the Poyang Lake basin (160,000 km2) and the period 1979–1986 using a two‐nest approach covering East Asia (30 km) and the Poyang Lake basin (10 km) driven by ERA Interim. Stand‐alone WRF effectively simulates temperature (bias 0.5°C) and precipitation (bias 21–26%). Stand‐alone HMS simulations provide reasonable streamflow estimates. A significant impact on the regional water balance was found if groundwater‐unsaturated zone interaction is considered. But the differences between the two groundwater coupling approaches are minor. For the fully coupled model system, streamflow results strongly depend on the simulation quality for precipitation. Two‐way interaction results in net upward water fluxes in up to 25% of the basin area after the rainy season. In total, two‐way interaction increases basin averaged recharge amounts. The evaluation with CPC and GLEAM indicates a better performance of the fully coupled simulation. The impact of groundwater coupling on LSM and atmospheric variables differs. Largest differences occur for the variable recharge (26%), whereas for atmospheric variables, the basin‐averaged impact is minor (<1%). But locally, a spatial redistribution up to ±5% occurs for precipitation.
