Published: February 2015

ABSTRACTIn this work, we describe a novel and cost effective approach based on optical fiber microcavities, for sensing high temperature values (up to 1150°C). The proposed sensor is produced by splicing standard single mode optical fibers with fibers destroyed by the catastrophic fuse effect, resulting in a microcavity structure in the fiber core region. These microcavities have a thermal sensitivity of 10.43 ± 0.15 pm °C−1, for temperatures up to 1150°C, which compares well with the sensitivity of Fabry–Perot interferometric sensing cavities but with the advantage of substantially reduced manufacturing costs. © 2015 Wiley Periodicals, Inc.

An integrated “sense‐and‐communicate” broad‐/narrow‐band optically controlled reconfigurable antenna for cognitive radio systems
Authors: Liu XiongYing , Fan Yi , Tentzeris Manos M. 
Published: February 2015

ABSTRACTAn optically controlled reconfigurable antenna with operability in both wide and narrow bands is investigated for cognitive radio systems. The proposed antenna consists of a U‐shaped patch for the spectrum sensing over a wide band and two open annuli for communication in narrow sub‐bands within the frequency range of 3.1–10.6 GHz. The integration of narrow and wide bands devices makes the whole antenna structure compact with a dimension of 40 × 38.5 mm2. With an inherent property of being electromagnetically transparency, four appropriately placed laser‐controlled photoconductive silicon switches are adopted to achieve reconfigurable frequency characteristics in the four bands of 5.8–6.8, 6.7–7.3, 7.0–8.4, and 7.9–9.2 GHz with the reflection coefficient below ‐10 dB. The wide‐narrowband antenna is fed by two coplanar waveguides with the isolation of S21 < −15 dB, effectively allowing the spectrum sensing and the communication to operate simultaneously. An antenna prototype has been fabricated, and close agreement is observed between the measured and simulated results. © 2015 Wiley Periodicals, Inc. Microwave Opt Technol Lett 57:1016–1023, 2015

ABSTRACTBeer–Lambert law deviation is often observed. Here, we propose alternative wavelength 279.95 nm for ozone concentration measurement between 357 and 971 μL L−1 to preserve linearity. Sensor loses linearity below transmittance 0.2165, as sensor approaches saturation. We recommend measurement of ozone concentration above transmittance of 0.2165 for strong linear relation. © 2015 Wiley Periodicals, Inc. Microwave Opt Technol Lett 57:1013–1016, 2015
Optimization of a regularized distortion measure to generate curved high‐order unstructured tetrahedral meshes
Authors: Gargallo‐Peiró A. , Roca X. , Peraire J. , Sarrate J. 
Published: February 2015

SummaryWe present a robust method for generating high‐order nodal tetrahedral curved meshes. The approach consists of modifying an initial linear mesh by first, introducing high‐order nodes, second, displacing the boundary nodes to ensure that they are on the computer‐aided design surface, and third, smoothing and untangling the mesh obtained after the displacement of the boundary nodes to produce a valid curved high‐order mesh. The smoothing algorithm is based on the optimization of a regularized measure of the mesh distortion relative to the original linear mesh. This means that whenever possible, the resulting mesh preserves the geometrical features of the initial linear mesh such as shape, stretching, and size. We present several examples to illustrate the performance of the proposed algorithm. Furthermore, the examples show that the implementation of the optimization problem is robust and capable of handling situations in which the mesh before optimization contains a large number of invalid elements. We consider cases with polynomial approximations up to degree ten, large deformations of the curved boundaries, concave boundaries, and highly stretched boundary layer elements. The meshes obtained are suitable for high‐order finite element analyses. Copyright © 2015 John Wiley & Sons, Ltd.
Protocol sequence and control co‐design for a collection of networked control systems
Authors: Guo Ge , Wen Shixi 
Published: February 2015

SummaryThis paper is concerned with the simultaneous stabilization of a collection of plants shared by the wireless network with capacity limitation. We use most regular binary sequences (MRBS) to control the medium access status of the plants. The design procedure of the scheduling policy translates to determine two parameters of the MRBS. With the MRBS protocol, each plant is essentially a sampled‐data control system with time varying sampling intervals. We derive a sufficient condition for determining the MRBS protocol that guarantees the controllability, observability, and stability of each plant. Most importantly, we give a methodology for MRBS protocol and controller co‐design, in which the controller has switching gains that are piecewise constant and dependent on the sampling intervals yielded by the MRBS. The main results are established using piecewise Lyapunov functional and the average dwell time technique. It is shown that the method can guarantee simultaneous stabilization of the collection of plants robustly in situations where the controller gain does not match the sampling interval or the sampling interval violates the maximum allowable transmission interval criteria. A numerical example is given to demonstrate the effectiveness of the co‐design method. Copyright © 2015 John Wiley & Sons, Ltd.
Actuator fault‐tolerant control of ocean surface vessels with input saturation
Authors: Chen Mou , Jiang Bing , Cui Rongxin 
Published: February 2015

SummaryIn this paper, an actuator robust fault‐tolerant control is proposed for ocean surface vessels with parametric uncertainties and unknown disturbances. Using the backstepping technique and Lyapunov synthesis method, the adaptive tracking control is first developed by incorporating the actuator configuration matrix and considering actuator saturation constraints. The changeable actuator configuration matrix caused by rotatable propulsion devices is considered. Next, the actuator fault‐tolerant control is developed for the case when faults occur in propulsion devices of the ocean surface vessel. Rigorous stability analysis is carried out to show that the proposed fault‐tolerant control can guarantee the stability of the closed‐loop system under certain actuator failure. Finally, simulation studies are given to illustrate the effectiveness of the proposed adaptive tracking control and fault‐tolerant control. Copyright © 2015 John Wiley & Sons, Ltd.

Published: February 2015

SummaryThis study investigated the effects of different surface treatments on the repair bond strength of yttrium‐stabilized tetragonal zirconia polycrystalline ceramic (Y‐TZP) zirconia to a composite resin. Sixty Y‐TZP zirconia specimens were prepared and randomly divided into six groups (n = 10) as follows: Group 1, surface grinding with Cimara grinding bur (control); Group 2, sandblasted with 30 µm silica‐coated alumina particles; Group 3, Nd:YAG laser irradiation; Group 4, Er,Cr:YSGG laser irradiation; Group 5, sandblasted + Nd:YAG laser irradiation; and Group 6, sandblasted + Er,Cr:YSGG laser irradiation. After surface treatments, the Cimara® System was selected for the repair method and applied to all specimens. A composite resin was built‐up on each zirconia surface using a cylindrical mold (5 × 3 mm) and incrementally filled. The repair bond strength was measured with a universal test machine. Data were analyzed using a one‐way ANOVA and a Tukey HSD test (p = 0.05). Surface topography after treatments were evaluated by a scanning electron microscope (SEM). Shear bond strength mean values ranged from 15.896 to 18.875 MPa. There was a statistically significant difference between group 3 and the control group (p < 0.05). Also, a significant increase in bond strength values was noted in group 6 (p < 0.05). All surface treatment methods enhanced the repair bond strength of the composite to zirconia; however, there were no significant differences between treatment methods. The results revealed that Nd:YAG laser irradiation along with the combination of sandblasting and Er,Cr:YSGG laser irradiation provided a significant increase in bond strength between the zirconia and composite resin.

Published: February 2015

AbstractAn industrial oxidative ladle refining process of metallurgical grade silicon has been experimentally examined. An extensive industrial sampling campaign has been performed and samples of silicon and slag have been analyzed by inductively coupled plasma mass spectroscopy (ICP-MS). The elemental concentrations of 45 elements have been evaluated with respect to sampling time during the refining process. Major elements, such as Ca and Al, as well as trace elements are studied. The refining kinetics is discussed and groups of elements with different behaviors are distinguished. For 21 elements, which are responsive to the refining process, kinetic parameters are established. The alkaline and alkaline earth elements are identified as having the highest refining rates, whereas the rare earth elements are slower and most transition metals are quite unresponsive to the oxidative refining operation.
Current Trends in Management of Fetal Growth Restriction
Authors: Gujral Kanwal , Nayar Sakshi 
Published: February 2015

AbstractFetal growth restriction (FGR) or intrauterine growth restriction (IUGR) are the terms used for a fetus which has not attained its full growth potential. FGR fetus is associated with high perinatal and neonatal morbidity and mortality, besides long term neurological handicap because of in utero hypoxia. Three decades of research has indicated that almost all treatment strategies are ineffective in treating FGR. Panorama of management includes identifying women at risk, correct dating, distinguishing between a constitutionally small and a true FGR, monitoring for fetal hypoxia, growth, and a timely intervention to avoid death or damage.

Emergency obstetric care: Making the impossible possible through task shifting
Authors: Schneeberger Caroline , Mathai Matthews 
Published: February 2015

AbstractTask shifting—moving tasks to healthcare workers with a shorter training—for emergency obstetric care (EmOC) can potentially improve access to lifesaving interventions and thereby contribute to reducing maternal and neonatal morbidity and mortality. The present paper reviews studies on task shifting for the provision of EmOC. Most studies were performed in Sub‐Saharan Africa and South Asia and focused primarily on task shifting for the performance of cesarean deliveries. Cesarean delivery rates increased following EmOC training without significant increase in adverse outcomes. The paper discusses the advantages and disadvantages of task shifting in EmOC and the role of this approach in improving maternal and newborn health in the short and long term.

Authors: Tabinda Hasan , Mahmood Fauzi 
Published: February 2015

Background De Quervain's tenosynovitis is a common cause of wrist pain in pregnant and postpartum females. This study provides objective evidence regarding the therapeutic efficacy of phonophoresis in treating de Quervain's disease during pregnancy. Methods In a single blind, randomised, controlled trial (n = 50), ketoprofen phonophoresis was given to the intervention group and conventional ultrasound (US) was given to controls, coupled with thumb splint immobilisation, and supervised strengthening and stretching exercises for 1 month. Symptomatic and functional improvement was assessed by visual pain analogue, grip, tip, key, and palmer pinch scales. Results There was a statistically significant improvement in the intervention group compared to the control group in grip and pinch strength, and pain reduction. Conclusion Ketoprofen phonophoresis as an adjunct to supervised exercise and splint immobilisation is a safe and effective therapy for de Quervain's tenosynovitis during pregnancy. Phonophoresis augments the benefits of US in terms of reducing pain and inflammation, and improving functional strength.
Vulnerabilidad y representación social de género en mujeres de una comunidad migrante
Authors: Flores Palacios Fátima 
Published: February 2015

En este trabajo se expone la concepción de vulnerabilidad de género que se ha venido construyendo desde hace al menos una década, a partir del análisis de fenómenos sociales que se expresan en contextos de pobreza y migración; particularmente nos hemos enfocado al tema de la salud. Nuestro trabajo ha adquirido cierta relevancia específicamente en relación a la salud mental y el tema de vih/sida y sus implicaciones en el sistema relacional de las personas. Ubicamos dimensiones que están presentes y naturalizadas a través de un sistema consensuado de representaciones sociales, lo que podríamos resumir como mandatos de género tanto en hombres como en mujeres. Se analiza específicamente el efecto subjetivo y emocional que presentan mujeres de una comunidad con características migratorias y en extrema pobreza, así como sus representaciones sociales acerca de su trayectoria de vida.

Authors: Gómez San Luis Anel Hortensia 
Published: February 2015

Debido al crecimiento exponencial de la explotación sexual comercial en los últimos años, hoy este fenómeno forma parte de las preocupaciones sociales a nivel global. La presente investigación utiliza la teoría de representaciones sociales para acercarse al proceso de construcción social de significados asociados a la prostitución de niñas y adolescentes, entre comerciantes de la comunidad de La Merced de la Ciudad de México. Esto se realiza con la intención de orientar dicha teoría hacia la prevención de la explotación. En el texto se alude a las representaciones sociales sobre género, sexualidad, niñez y adolescencia, prostitución, trabajo y comercio, como los aspectos centrales que sustentan la explotación de niñas y adolescentes e impiden un cambio estructural.
Indonesian Opposition in the Colonial Municipality: A Minahasser in Bandung
Authors: OTTO Jan Michiel 
Published: February 2015

AbstractThis article discusses politico-legal relations and actual decision-making in urban government in late colonial Indonesia, notably in the municipality of Bandung. On the basis of verbatim reports of council meetings in the early 1920s,1the article catches the atmosphere of hot debates touching upon the core problem of colonial rule, namely inequality between racial groups. Decentralization and democratization in the colony had made such discussions unavoidable. The 1923 budgetary debate shows how eloquently elected representatives of the native population used the municipal council as a forum to plea for the interests of Indonesians. The colonial government referred to autonomy of urban desas to justifylaissez-faireapproaches to natives’ interests. The municipality was in doubt for, at the same time, colonial administration was transitioning from a minimalist to a welfare state model. Hence, notwithstanding their differences, the common ambition to develop Bandung, albeit in a colonial context and led by the mayor, contributed to co-operative attitudes.

A multivariate approach to infer locomotor modes in Mesozoic mammals
Authors: Chen Meng , Wilson Gregory P. 
Published: February 2015

AbstractEcomorphological diversity of Mesozoic mammals was presumably constrained by selective pressures imposed by contemporary vertebrates. In accordance, Mesozoic mammals for a long time had been viewed as generalized, terrestrial, small-bodied forms with limited locomotor specializations. Recent discoveries of Mesozoic mammal skeletons with distinctive postcranial morphologies have challenged this hypothesis. However, ecomorphological analyses of these new postcrania have focused on a single taxon, a limited region of the skeleton, or have been largely qualitative.For more comprehensive locomotor inference in Mesozoic mammals, we applied multivariate analyses to a morphometric data set of extant small-bodied mammals. We used 30 osteological indices derived from linear measurements of appendicular skeletons of 107 extant taxa that sample 15 orders and eight locomotor modes. Canonical variate analyses show that extant small-bodied mammals of different locomotor modes have detectable and predictable morphologies. The resulting morphospace occupation reveals a morphofunctional continuum that extends from terrestrial to scansorial, arboreal, and gliding modes, reflecting an increasingly slender postcranial skeleton with longer limb output levers adapted for speed and agility, and extends from terrestrial to semiaquatic/semifossorial and fossorial modes, reflecting an increasingly robust postcranial skeleton with shorter limb output levers adapted for powerful, propulsive strokes. We used this morphometric data set to predict locomotor mode in ten Mesozoic mammals within the Docodonta, Multituberculata, Eutriconodonta, “Symmetrodonta,” and Eutheria. Our results indicate that these fossil taxa represent five of eight locomotor modes used to classify extant taxa in this study, in some cases confirming and in other cases differing from prior ecomorphological assessments. Together with previous locomotor inferences of 19 additional taxa, these results show that by the Late Jurassic mammals had diversified into all but the saltatorial and active flight locomotor modes, and that this diversification was greatest in the Eutriconodonta and Multituberculata, although sampling of postcranial skeletons remains uneven across taxa and through time.
Should Creditors Rely on the Solvency and Liquidity Threshold for Protection? A South African Case Study
Authors: Bradstreet Richard S 
Published: February 2015

AbstractMany jurisdictions internationally have adopted some form of solvency-based threshold to protect creditors from opportunistic or abusive distributions being paid from corporate capital. When a legislative “test” for distributions involves an enquiry that is too heavily based on a company's balance sheet, and thus on the integrity of the financial reporting standards underpinning its preparation, the utility of such thresholds becomes questionable on a similar basis to that on which the effectiveness of the capital maintenance doctrine has been challenged. Even the addition of a “liquidity” threshold that shifts the emphasis away from a company's balance sheet appears to presume that a corporation's financial health can be accurately determined from its financial statements. This article explores the difficulties involved in so-called “solvency-based” thresholds for distributions and considers other sources of creditor protection that may be more reliable.
Reproductive biology of the seastar Ceramaster grenadensis from the deep north-western Mediterranean Sea

Published: February 2015

Ceramaster grenadensis is one of the most abundant bathyal seastars in the north-western Mediterranean Sea and also presents a wide geographic distribution in the Atlantic Ocean. As with other species in this genus, little information is available on the biology and reproductive strategy of C. grenadensis. In this context, we describe for the first time the reproductive cycle of this species from bathyal depths in the north-western Mediterranean Sea. Specimens (N = 141) were collected seasonally from 194 benthic trawls (141 Otter Trawls and 53 Agassiz trawls) conducted during 10 cruises from October 2008 to April 2013. Open slope and canyon systems were sampled at depths between 900 and 2250 m. The population distribution of C. grenadensis showed a depth-related structure, with the smaller adult specimens and juveniles present at greater depths. Sex ratio was 2:1 females per male, constant among seasons and depths. Histological analyses of the gonads showed an asynchronous ovarian organization, with previtellogenic and vitellogenic oocytes throughout the year. These oogenesis patterns suggest a continuous reproduction. However, the Pyloric Caeca Index (PCI) decreased in summer while the Gonad Index (GI) increased in autumn in males, suggesting a higher spawning capacity in autumn. In both sexes, an increasing GI and PCI trend was observed with increasing depth.
