Authors: Kang Joon‐Myung , Ju Hong‐Taek , Choi Mi‐Jung , Hong James Won‐Ki , Kim Jun‐Gu 
Published: May 2009

AbstractMobile devices (e.g. mobile handsets or PDAs) have gained much functionality and intelligence with the growth of mobile network technologies and the increased use of mobile services. As a consequence, mobile devices have become more complex and many related problems have occurred. Specifically, sudden rebooting and freezing problems caused by software faults decrease the availability of the mobile device and cause inconvenience to end‐users. To solve such problems, academia and industry have focused on Open Mobile Alliance (OMA) Device Management (DM); this method is the internationalde factostandard for mobile device management. In this paper, we propose a software fault management method to remotely determine and correct problems of mobile devices based on OMA DM. We present a definition of management objects and a method to collect them from mobile devices using the OMA DM protocol. We also present a method for debugging and correcting software faults using the collected information. Finally, we present a prototype implementation and performance evaluation to validate our proposed method. Results of the performance evaluation show that our proposed method is efficient and scalable in regard to network traffic overhead and response time. Copyright © 2009 John Wiley & Sons, Ltd.
Robust sliding mode design for uncertain stochastic systems based onH∞control method
Authors: Niu Yugang , Wang Zidong , Wang Xingyu 
Published: May 2009

AbstractIn this paper, the design problem of sliding mode control (SMC) is addressed for uncertain stochastic systems modeled by Itô differential equations. There exist the parameter uncertainties in both the state and input matrices, as well as theunmatchedexternal disturbance. The key feature of this work is the integration of SMC method withH∞technique such that the robust stochastic stability with a prescribed disturbance attenuation levelγcan be achieved. A sufficient condition for the existence of the desired sliding mode controller is obtained via linear matrix inequalities. The reachability of the specified sliding surface is proven. Finally, a numerical simulation example is presented to illustrate the proposed method. Copyright © 2009 John Wiley & Sons, Ltd.
Minimal‐power control of hydrogen evolution reactions
Authors: Costanza Vicente , Rivadeneira Pablo S. 
Published: May 2009

AbstractAn integral approach to solve finite‐horizon optimal control problems posed by set‐point changes in electrochemical hydrogen reactions is developed. The methodology extends to nonlinear problems with regular, convex Hamiltonians that cannot be explicitly minimized, i.e. where the functional dependence of the H‐minimal control on the state and costate variables is not known. The Lagrangian functions determining trajectory costs will not have special restrictions other than positiveness, but for simplicity the final penalty will be assumed quadratic. The answer to the problem is constructed through the solution to a coupled system of three first‐order quasi‐linear partial differential equations (PDEs) for the missing boundary conditions x(T), λ(0) of the Hamiltonian equations, and for the final value of the control variable u(T). The independent variables of these PDEs are the time‐duration T of the process and the characteristic parameter S of the final penalty. The solution provides information on the whole (T, S)‐family of control problems, which can be used not only to construct the individual optimal control strategies online, but also for global design purposes.

Bronchioloalveolar carcinoma as a second malignancy in osteosarcoma survivors
Authors: Lebensburger Jeffrey , Katzenstein Howard , Jenkins Jesse J. , Rodriguez‐Galindo Carlos 
Published: May 2009

AbstractSecond malignancies occur in 2–3% of survivors of pediatric osteosarcoma; treatment‐related hematologic and solid malignancies have both been described. We present two cases of patients with pulmonary nodules that developed more than 2 years after treatment of osteosarcoma. Both lesions were completely resected and pathology revealed bronchioloalveolar carcinoma (BAC). Primary BAC is extremely rare in children; however, cases of this malignancy have been described in survivors of pediatric cancer. BAC may present as a solitary pulmonary nodule indistinguishable from a metastatic lesion and should be included in the differential diagnosis of pulmonary nodules in survivors of pediatric cancer.

Authors: Orriols Ludivine , Salmi Louis‐Rachid , Philip Pierre , Moore Nicholas , Delorme Bernard , Castot Anne , Lagarde Emmanuel 
Published: May 2009

AbstractPurposeTo evaluate the quality of epidemiological research into effects of medicinal drugs on traffic safety and the current knowledge in this area.Data sourcesThe bibliographic search was done in Medline electronic database using the keywords: ((accident* or crash*) and traffic and drug*) leading to 1141 references. Additional references were retrieved from the Safetylit website and the reference lists of selected studies. Original articles published in English or French, between 1 April 1979 and 31 July 2008, were considered for inclusion. We excluded descriptive studies, studies limited to alcohol or illicit drug involvement and investigations of injuries other than from traffic crashes. Studies based on laboratory tests, driving simulators or on‐the‐road driving tests were also excluded. Eligible studies had to evaluate the causal relationship between the use of medicinal drugs and the risk of traffic crashes. Study quality was assessed by two independent experts, according to a grid adapted from the strengthening the reporting of observational studies in epidemiology (STROBE) statement.ResultsTwenty two studies of variable methodological quality were included. Definition of drug exposure varied across studies and depended on the data sources. Potential confounding due to the interaction between the effects of the medicinal drug and disease‐related symptoms was often not controlled. The risk of motor‐vehicle crashes related to benzodiazepines has been amply studied and demonstrated. Results for other medicinal drugs remain controversial.ConclusionThere is a need for large studies, investigating the role of individual substances in the risk of road traffic crashes.

Synthesis and photophysical behavior of a water‐soluble coumarin‐bearing polymer for proton and Ni2+ ion sensing
Authors: Wang Bao‐Yan , Liu Xing‐Yu , Hu Yu‐Lin , Su Zhi‐Xing 
Published: May 2009

AbstractBACKGROUND: In recent years, many fluorescent chemosensors with various macromolecular structures have been prepared for the detection of protons or metal cations in the environment. Most of this research is focused on polymer sensors with fluorescent recognition sites in the main chain. In this case, the fluorescent recognition sites are covalently bonded to the polymer chain, and thus the polymer shows photophysical properties as a chemosensor for protons and metal ions.RESULTS: An acrylic monomer bearing coumarin moieties, 7‐hydroxy‐4‐methyl‐8‐(4′‐acryloylpiperazin‐1′‐yl)methylcoumarin, was synthesized. This was then copolymerized with N‐vinylpyrrolidone to obtain a blue fluorescent material. The fluorescent copolymer has good solubility in aqueous solution. Its main photophysical properties were determined in relation to its use as a sensor for protons and metal cations. It is an efficient ‘off‐on’ switcher for pH between 3.02 and 12.08. Additionally, the polymer sensor is selective to Ni2+ ions, with the increase in the fluorescence intensity depending on Ni2+ ion concentrations in the range 0.33 × 10−5–7.67 × 10−5 mol L−1.CONCLUSION: The results suggest that this copolymer may offer potential as a reusable polymer sensor for protons and Ni2+ ions in aqueous solution.

Published: May 2009

AbstractObjectives: Expanding the existing Breast Cancer Family Registry (BCFR) to enrol daughters aged 6–17 years in a prospective cohort study named LEGACY (Lessons in Epidemiology and Genetics of Adult Cancer from Youth) offers the opportunity to study the effects of genetic and environmental exposures in youth on adult breast cancer risk. Few studies have assessed parents' willingness to enrol their daughters in genetic epidemiological cohort studies. Since BCFR parents are the gatekeepers of their daughters' future enrolment, it is important to explore their interests and attitudes towards LEGACY.Methods: Semi‐structured telephone interviews were conducted with 85 BCFR participant parents at 3 BCFR sites in Ontario, Canada, and in Utah and Northern California. We explored parents' thoughts and feelings (interests and attitudes) regarding their daughters' enrolment in LEGACY and different data collection modalities. Qualitative analysis of audiotaped interviews was carried out utilizing an inductive content analysis.Results: Parents' acceptance of three data collection modalities were 92% (78/85) for questionnaire data, 87% (74/85) for biological samples and 63% (46/73) for physical examination for pubertal staging. The parents' primary motivation for participation was altruistic. Their concerns regarding their daughters' participation centered on exacerbating awkward pubertal feelings, increasing cancer anxiety, respecting autonomy and maturity, privacy and future use of data and logistical impediments.Conclusion: Parents demonstrated a high level of interest in the creation of LEGACY. Their motivation to participate was balanced by their desire to protect daughters from undue harm. These interviews contributed valuable information for the design of LEGACY.

Management of the pediatric organ donor to optimize lung donation
Authors: Mallory George B. , Schecter Marc G. , Elidemir Okan 
Published: May 2009

AbstractLung transplantation in childhood is a highly specialized clinical practice confined to a few centers around the world. Organ availability remains an important limiting factor in extending the application of this procedure to more infants, children and adolescents. The lungs are the organ most vulnerable to injury, infection and dysfunction among transplantable organs in the brain dead deceased donor. In this manuscript, we review the pathophysiology of the most common and important disease states that affect the lungs in potential donors. Furthermore, we herein provide recommendations for optimal management of the pediatric organ donor with an emphasis on strategies to improve the opportunity for the lungs to be placed in candidates on the transplant list.

Published: May 2009

AbstractBACKGROUND: The increasing occurrence of Qo inhibitor (QoI)‐fungicide‐resistant Plasmopara viticola (Berk. & MA Curtis) Berl. & DeToni populations is becoming a serious problem in the control of grapevine downy mildew worldwide.RESULTS: The authors have developed a rapid method for detecting resistance to a QoI fungicide, azoxystrobin, in P. viticola populations using the nested PCR‐RFLP method. With this method, a glycine‐to‐alanine substitution was discovered at codon 143 in the cytochrome b gene of P. viticola populations found in Japan.CONCLUSION: It is proposed that the nested PCR‐RFLP method is a high‐speed, sensitive and reliable tool for detecting azoxystrobin‐resistant P. viticola populations.

Baseline sensitivity to proquinazid in Blumeria graminis f. sp. tritici and Erysiphe necator and cross‐resistance with other fungicides
Authors: Genet Jean‐Luc , Jaworska Grazyna 
Published: May 2009

AbstractBACKGROUND: Proquinazid is a new quinazolinone fungicide from DuPont registered in most European countries for powdery mildew control in cereals and vines. The aim of this paper is to present baseline sensitivity data in populations of Blumeria graminis f. sp. tritici EM Marchal and Erysiphe necator (Schw) Burr as well as results from cross‐resistance studies with other fungicides.RESULTS: Proquinazid exhibited a high intrinsic activity on B. graminis f. sp. tritici isolates at rates ranging from 0.000078 to 0.02 mg L−1. Erysiphe necator isolates were comparatively less sensitive to proquinazid, with EC50 values ranging from 0.001 to 0.3 mg L−1. Proquinazid controlled equally well B. graminis f. sp. tritici isolates sensitive and resistant or less sensitive to tebuconazole, fenpropimorph, fenpropidin, cyprodinil and kresoxim‐methyl. A positive correlation (r = 0.617) between quinoxyfen and proquinazid sensitivities was found among 51 B. graminis f. sp. tritici isolates. Quinoxyfen‐resistant B. graminis f. sp. tritici isolates were slightly less sensitive to proquinazid than the quinoxyfen‐sensitive isolates; however, proquinazid remained much more active than quinoxyfen on these isolates. A stronger sensitivity relationship (r = 0.874) between proquinazid and quinoxyfen was found among 65 E. necator isolates tested in a leaf disc assay. The sensitivity values for proquinazid were significantly lower than those for quinoxyfen, confirming the higher intrinsic activity of proquinazid on both pathogens.CONCLUSION: Given the history of resistance development in powdery mildew and the observed sensitivity relationship with quinoxyfen, specifically in E. necator, we conclude that the risk of resistance developing to proquinazid might be influenced by the use of quinoxyfen. Based on these results, the authors recommend that proquinazid and quinoxyfen be managed together for resistance management. Copyright © 2009 Society of Chemical Industry
Insecticide resistance status of Bemisia tabaci Q‐biotype in south‐eastern Spain
Authors: Fernández Esther , Grávalos Carolina , Haro Pedro Javier , Cifuentes Dina , Bielza Pablo 
Published: May 2009

AbstractBACKGROUND: Bemisia tabaci Gennadius Q‐biotype has readily developed resistance to numerous insecticide classes. Studies in the Mediterranean area are needed to clarify the resistance status and cross‐resistance patterns in this invasive whitefly biotype. The levels of resistance in nymphs of seven strains of B. tabaci Q‐biotype from south‐eastern Spain to representative insecticides were determined.RESULTS: Six populations had low to moderate levels of resistance to azadirachtin (0.2‐ to 7‐fold), buprofezin (11‐ to 59‐fold), imidacloprid (1‐ to 15‐fold), methomyl (3‐ to 55‐fold), pyridaben (0.9‐ to 9‐fold), pyriproxyfen (0.7‐ to 15‐fold) and spiromesifen (1‐ to 7‐fold), when compared with a contemporary Spanish Q‐biotype reference population (LC50 = 2.7, 8.7, 15.2, 19.9, 0.34, 20.9 and 1.1 mg L−1 respectively). A single population collected from a greenhouse subject to intensive insecticide use exhibited generally higher resistance levels to the same array of compounds (31‐, 1164‐, 3‐, 52‐, 9‐, 19‐ and 3‐fold respectively). Pyridaben and spiromesifen were extremely effective against nymphs of all strains, with LC50 values significantly below recommended application rates.CONCLUSION: In contrast to previous reports, high rates of efficacy exist for numerous insecticide classes against B. tabaci Q‐biotype populations in these intensive agricultural regions of south‐eastern Spain. This probably reflects the recent and significant reductions in exposure that have resulted from a wider uptake of IPM technologies and strategies. However, the continued presence of resistance genes also suggests that a reversion to levels of high insecticide exposure could result in a rapid selection for resistance.

Synthesis and insecticidal activity of new pyrethroids
Authors: Silvério Flaviano O , de Alvarenga Elson S , Moreno Shaiene C , Picanço Marcelo C 
Published: May 2009

AbstractBACKGROUND: Pyrethroids are among the most potent pesticides known, with great potential for structural variation with retention or enhancement of potency. The simple methyl ester is easier to prepare (at least one step shorter) than the more complex pyrethroids modified on the alcohol moiety. The objective was to synthesise methyl esters of pyrethroid acids containing an aromatic ring on the acid moiety and evaluate their biological activity against Ascia monuste orseis Latr., Tuta absoluta Meyrick, Periplaneta americana (L.), Musca domestica L. and Sitophilus zeamais (Motsch.).RESULTS: The synthetic sequence required seven steps: protection of the hydroxyl groups of D‐mannitol, diol oxidative cleavage with sodium metaperiodate, alkene formation by Wittig reaction with methoxycarbonylmethylidene(triphenyl)phosphorane, cyclopropanation, acetal hydrolysis with perchloric acid and oxidative cleavage with sodium metaperiodate gave methyl (1S, 3S)‐3‐formyl‐2,2‐dimethylcyclopropane‐1‐carboxylate. The final step comprised reaction of the aldehyde with five different aromatic phosphorus ylides to give the pyrethroids.CONCLUSION: An efficient and versatile synthesis of ten new pyrethroid methyl esters has been accomplished from the readily available D‐mannitol in seven steps. All compounds showed insecticidal activity, and methyl (1S, 3S)‐3‐[(Z)‐2‐(4‐chlorophenyl)vinyl]‐2,2‐dimethylcyclopropane‐1‐carboxylate was the most active, killing 90% of A. monuste orseis and 100% of T. absoluta and P. americana.

Rapid screening and characterization of drug metabolites using multiple ion monitoring dependent product ion scan and postacquisition data mining on a hybrid triple quadrupole‐linear ion trap mass spectrometer
Authors: Yao Ming , Ma Li , Duchoslav Eva , Zhu Mingshe 
Published: May 2009

AbstractMultiple ion monitoring (MIM)‐dependent acquisition with a triple quadrupole‐linear ion trap mass spectrometer (Q‐trap) was previously developed for drug metabolite profiling. In the analysis, multiple predicted metabolite ions are monitored in both Q1 and Q3 regardless of their fragmentations. The collision energy in Q2 is set to a low value to minimize fragmentation. Once an expected metabolite is detected by MIM, enhanced product ion (EPI) spectral acquisition of the metabolite is triggered. To analyze in vitro metabolites, MIM‐EPI retains the sensitivity and selectivity similar to that of multiple reaction monitoring (MRM)‐EPI in the analysis of in vitro metabolites. Here we present an improved approach utilizing MIM‐EPI for data acquisition and multiple data mining techniques for detection of metabolite ions and recovery of their MS/MS spectra. The postacquisition data processing tools included extracted ion chromatographic analysis, product ion filtering and neutral loss filtering. The effectiveness of this approach was evaluated by analyzing oxidative metabolites of indinavir and glutathione (GSH) conjugates of clozapine and 4‐ethylphenol in liver microsome incubations. Results showed that the MIM‐EPI‐based data mining approach allowed for comprehensive detection of metabolites based on predicted protonated molecules, product ions or neutral losses without predetermination of the parent drug MS/MS spectra. Additionally, it enabled metabolite detection and MS/MS acquisition in a single injection. This approach is potentially useful in high‐throughout screening of metabolic soft spots and reactive metabolites at the drug discovery stage. Copyright © 2009 John Wiley & Sons, Ltd.
MDPA: multidimensional privacy‐preserving aggregation scheme for wireless sensor networks
Authors: Lin Xiaodong , Lu Rongxing , Shen Xuemin (Sherman) 
Published: May 2009

AbstractIn this paper, we propose a novel multidimensional privacy‐preserving data aggregation scheme for improving security and saving energy consumption in wireless sensor networks (WSNs). The proposed scheme integrates the super‐increasing sequence and perturbation techniques into compressed data aggregation, and has the ability to combine more than one aggregated data into one. Compared with the traditional data aggregation schemes, the proposed scheme not only enhances the privacy preservation in data aggregation, but also is more efficient in terms of energy costs due to its unique multidimensional aggregation. Extensive analyses and experiments are given to demonstrate its energy efficiency and practicability. Copyright © 2009 John Wiley & Sons, Ltd.
