Published: April 2017

In this paper, a series of polysiloxanes, presenting different contents of densely simple and well‐defined short‐branched chains (G1–G5), are prepared by hydrosilylation of α,ω‐(dimethylvinylsiloxy)‐poly(dimethyl‐methylvinyl)siloxanes (P1–P5) with 1,1,1,3,5,5,5‐heptamethyltrisiloxane (MDHM) and characterized by1H and29Si nuclear magnetic resonance, Fourier transform‐infrared spectroscopy, Abbe refractometry, gel permeation chromatography, and differential scanning calorimetry. The rheological behaviors of the G1–G5products are investigated to study the influences of the short‐branched chains. The rheological parameters including non‐Newtonian index (n) and the flow activation energy (ΔEη) are obtained and discussed. It is observed that the G1–G5polymers belonged to pseudoplastic fluids and the ΔEηvalues of the G1–G5products are significantly influenced by the short‐chain branching degree of the polymers.image

Published: April 2017

AbstractThe aim of this paper is to study mixed multiplier ideals associated with a tuple of ideals in a two‐dimensional local ring with a rational singularity. We are interested in the partition of the real positive orthant given by the regions where the mixed multiplier ideals are constant. In particular we reveal which information encoded in a mixed multiplier ideal determines its corresponding jumping wall and we provide an algorithm to compute all the constancy regions, and their corresponding mixed multiplier ideals, in any desired range.

AbstractAcute‐phase inflammation plays a critical role in liver graft injury. Inflammasomes, multi‐molecular complexes in the cytoplasm, are responsible for initiating inflammation. Here, we aimed to explore the role of inflammasomes in liver graft injury and further to investigate the regulatory mechanism. In a clinical liver transplant cohort, we found that intragraft expression of nucleotide‐binding oligomerization domain‐like receptor family pyrin domain containing 3 (NLRP3) inflammasomes was significantly up‐regulated post‐transplantation. Importantly, overexpression of NLRP3 was strongly associated with poor liver function characterized by high levels of ALT, AST, and urea, as well as neutrophil infiltration after transplantation. The significant correlation between NLRP3 and IL‐1β mRNA levels led us to focus on one of the associated upstream regulators, telomere‐independent repressor activator protein 1 (RAP1), which was further proved to be co‐localized with NLRP3 in neutrophils. In the liver of a mouse model (hepatic ischaemia/reperfusion and hepatectomy model) and isolated neutrophils from RAP1−/− mice, the expression levels of NLRP3 and keratinocyte chemoattractant (KC) were significantly down‐regulated in contrast to those in wild types. The levels of ALT and AST, as well as the neutrophil infiltration, were also decreased by RAP1 deficiency. In our clinical validation, intragraft KC expression was associated with NLRP3 and co‐localized with RAP1 in neutrophils. Furthermore, NLRP3 inflammasomes were up‐regulated by recombinant KC in the isolated neutrophils and liver of the mouse model. Our data demonstrated that NLRP3 inflammasomes, activated by the RAP1/KC axis, played a critical role in initiating inflammation during the early stage of liver graft injury. Targeting RAP1/KC/NLRP3 inflammasomes may offer a new therapeutic strategy against liver graft injury. Copyright © 2017 Pathological Society of Great Britain and Ireland.

AbstractBackgroundThe use of high‐dose chemotherapy with autologous hematopoietic cell rescue (AuHCR) in Head Start III is a potentially curative approach for the management of young children with central nervous system neoplasms. We report the potential influence of quality and timing of radiation therapy on the survival of patients treated on the study.ProcedureBetween 2003 and 2009, 220 children with newly diagnosed central nervous system neoplasms were enrolled on the study. Radiation therapy was indicated following AuHCR for children between 6 and 10 years old or those younger than 6 years with residual tumor preconsolidation. Records were received for 42 patients and reviewed to determine adherence to protocol treatment volume and dose guidelines. Of these patients, seven were irradiated prior to consolidation, and additional four patients who initially avoided radiation therapy after AuHCR were subsequently treated at relapse.ResultsOf the 31 patients who were fully evaluable, 2 refused radiation therapy until recurrence and 4 progressed between recovery from AuHCR and radiation therapy. Of the remaining 25 patients, 8 had violations in their indication, dose, or treatment volume. All violations occurred in patients under 6 years of age. Two patients could have avoided radiation therapy. There were 6 violations in the 23 patients who received radiation therapy for guideline indications.ConclusionAll protocol violations occurred in patients under 6 years of age and were associated with decreased overall survival as was the time to start radiotherapy of greater than 11 weeks. When indicated, starting radiation therapy soon after neutrophil and platelet recovery may improve the outcome for these high‐risk children.

Published: April 2017

AbstractPurposeLarge medical record databases facilitate epidemiology research in fracture. However, the validity of fracture in the databases is needed to ensure the reliability of data. We aimed to assess the validity of International Classification of Diseases, 9th Revision (ICD‐9) code algorithms for identifying major osteoporotic fracture in the Clinical Data Analysis and Reporting System (CDARS) in Hong Kong.MethodsThe CDARS is a database developed by the Hong Kong Hospital Authority for research purpose. We used ICD‐9 code algorithm for identifying major osteoporotic fracture, including vertebral fracture, humerus fracture, forearm/wrist fracture, and hip fracture, in CDARS in 2005–2016. As high positive predictive value (PPV) is critically important in epidemiology research, we sought to determine the PPV of fracture diagnostic code in terms of ICD‐9 relative to the radiography imaging and clinical notes. A total of 380 major osteoporotic fracture cases (vertebral fracture: 101 cases; humerus fracture: 81 cases; forearm/wrist fracture: 94 cases; and hip fracture: 104 cases) were randomly selected and validated.ResultsIn 380 fracture cases, the overall PPV was 96.8%. In subgroup analysis, PPV of 100% was observed for hip, humerus, and forearm/wrist fractures, whereas PPV of 86% was observed for vertebral fracture.ConclusionsThe use of ICD‐9 code algorithm to identify major osteoporotic fracture in CDARS is a valid tool with a very high PPV. However, cautious interpretation is required when the study focuses on incident vertebral fracture. Copyright © 2017 John Wiley & Sons, Ltd.

Authors: Strang Abigail , Fischer Anthony J. , Chidekel Aaron 
Published: April 2017

SummaryIvacaftor was approved for rarer class‐III CFTR mutations including S549N in 2014. Since these mutations are uncommon, ongoing reports of patient experiences with Ivacaftor and these mutations are important. This case series describes the clinical effectiveness (including airway infection status, lung function, and growth) of Ivacaftor therapy in four pediatric Hispanic patients with S549N and F508del over 24 months. In these patients, Ivacaftor was highly efficacious with no further Pseudomonas‐positive cultures despite prior chronic colonization in three patients as well as notable improvements in lung function and growth. The remarkable improvements in lung function and growth were similar to G551D patients with more striking changes in airway infection status.

Published: April 2017

AbstractBACKGROUNDSeveral European countries are important walnut (Juglans regia L.) producers. However, these countries must contend with the recent introduction of the Walnut Husk Fly, Rhagoletis completa Cresson (Diptera, Tephritidae), which is causing severe economic losses, especially in organic production. Because most Tephritid fruit flies use kairomones in their search for host plants, we hypothesise that this highly specialist species orients toward the volatile blend released by walnut husks.RESULTSWe collected, identified, and quantified the volatile organic chemicals (VOCs) released by walnut husks from the most commonly cultivated variety in France (Franquette). Then, the behavioural response of R. completa toward synthetic odour blends was recorded in dual choice assays conducted in net cages. A total of 26 VOCs were identified, with α‐pinene, β‐pinene, trans‐linalool, eugenol, and tetradecane representing the major constituents. In the dual choice assay, male and female R. completa were strongly attracted to synthetic blend that included most of the identified husk VOCs.CONCLUSIONWhen searching for a host plant, R. completa use host fruit kairomones. The potential of these semiochemicals in monitoring and management of this quarantine pest is discussed. © 2017 Society of Chemical Industry
(Im)Mobilities of Older Pakistani Female Migrants and Material Culture: a Multigenerational Perspective on Gift‐Giving
Authors: Ali Nazia , Suleman Rukeya 
Published: April 2017

AbstractThe purpose of the paper is to discuss, from a multigenerational perspective, the (im)mobilities of older Pakistani women migrants in the UK and the material culture of gift‐giving, which moves with (and without) them to and from the ancestral homeland of Pakistan. A multigenerational perspective allows us to comprehend the collective importance of the mobilities of older Pakistani female migrants in upholding the culturally significant ritualistic custom of gift‐giving. The research is situated within the theoretical context of the ‘New Mobilities Paradigm’ to understand the mobility patterns of older migrants and the mobilisation of material culture. We find that the process of coordinating and exchanging gifts leads to a great deal of physical mobility, within localities and national spaces, but also internationally across different diasporic locations. In doing so, older Pakistani women migrants perform an important role as ‘gift agents’ in the host and home countries, assuring their own social status as well as that of their families. Importantly, the resulting mobility of older Pakistani women empowers their less mobile peers to also participate in gift‐giving. This paper concludes by extending the concept of ‘mobility practices’ to include the mobility of gifts as a practice, which can compensate for physical immobility in older age due to ill‐health, fragility, or other factors.

Diagnosis of seasonally varying regression slope coefficients and application to the MJO
Authors: Roundy Paul E. 
Published: April 2017

AbstractSimple linear regression is frequently applied to diagnose relationships between time series in weather and climate. Yet, when similar calculations are applied based on data from different times of the year, the coefficients vary. This article introduces a new algorithm to estimate seasonally varying regression slope coefficients. The algorithm generates a seasonal time series of the variance of the predictor and of covariance between the predictor and the predictand. It does so by fitting the seasonal cycle and select harmonics thereof to the time series of products between the values of the predictor and the predictand and to the time series of the squares of the values of the predictor. On a given day of the year, the resulting seasonal covariance divided by the seasonal variance constitutes the best fit to the regression slope coefficient on that day. The algorithm is tested on artificial data, compared with a previous algorithm with similar intent, and then applied to the relationship between a Madden–Julian Oscillation index and global atmospheric patterns. Statistical significance is assessed through a Monte Carlo technique that randomly selects from the sample of years included in a training set.
Infrared vibrational spectra, electronic structures, and formation reactions of polypyrrolic mono‐ and bis‐actinyl complexes: A relativistic DFT study
Authors: Zheng Xiu‐Jun , Qu Ning , Xuan Li‐Chun , Pan Qing‐Jiang 
Published: April 2017

AbstractThe development of synthetic techniques has enabled synthesis and characterization of a series of mono and bis‐uranyl complexes of octadentate polypyrrolic macrocycles such as aryl‐lined H4LAr and anthracenyl‐linked H4L, which is complemented by theoretical investigation via extending to more toxic and radioactive transuranics. The relativistic density functional theory (DFT) study has been dedicated to twelve actinyl complexes supported by the H4L ligand. The actinides include U, Np, and Pu elements, and either one or two is rendered in complexes with oxidation states of V or VI. Calculated symmetric/asymmetric An = O stretching vibrational frequencies show the decreasing trend along U, Np, and Pu, which is consistent with calculated bond orders. The hydrogen bonds between –yl endo‐oxo and remaining hydrogen atoms of pyrrolides in mononuclear complexes cause pronounced redshift of An = O vibrational frequencies compared to those in binuclear complexes, so does the reduction from hexa‐ to pentavalent complexes. The electronic structures of actinyl complexes were calculated. For example, B‐pyUVI possesses low‐lying U(5f)‐character virtual orbitals, where f(δ) and f(ϕ) orbitals occur in low‐energy region and π‐type ones are residing further high; the σ*(U = O) and σ(U = O) orbitals are significantly split over 7 eV. The previous experimental observation that the 1:1 reactions between uranyl salts and the macrocycle tend to give a mixture of bis‐ and mono‐uranyl complexes, with bis‐ the major product, has been corroborated by computational studies of the thermodynamics of the reactions.

AbstractBackgroundThe objective was to evaluate whether the new intraoperative C‐arm guiding system ClearGuide® (CG) reduces radiation exposure of the staff in an Orthopaedic and Trauma operation theatre.MethodsData of 95 patients CG was used were retrospectively compared using matched‐pair analysis with controls without CG. Radiation dose (RD), fluoroscopic time (FT) and operation time (OT) were analysed in ten types of operative procedures.ResultsUse of CG led to a significant reduction (p ≤ 0.05) of the RD in intramedullary nailing and plate fixation of femoral shaft fractures as well as plating of tibia shaft fractures. Concerning FT, use of CG led to a significant reduction (p ≤ 0.05) while performing kyphoplasties and plate fixation of femoral shaft fractures. Regarding OT, no statistical significance was observed.ConclusionsCG as a simple, reproducible and intuitive communication tool for C‐arm guidance reduces intraoperative staff radiation exposure especially while fixation of long bone fractures and in spine surgery.
How are changes in exposure to job demands and job resources related to burnout and engagement? A longitudinal study among Chinese nurses and police officers
Authors: Hu Qiao , Schaufeli Wilmar B. , Taris Toon W. 
Published: April 2017

AbstractThis study used a person‐centered approach to examine the across‐time relationships between job demands and job resources on the one hand and employee well‐being (burnout and work engagement) on the other. On the basis of the job demands–resources model and conservation of resources (COR) theory, increases in demands and decreases in resources across time were expected to result in unfavorable changes in well‐being across time. The results of a 2‐wave study among 172 nurses and 273 police officers showed several common patterns across both samples: (a) participants who experienced an increase of demands showed a significant increase in burnout, whereas participants who reported having low resources at both measurement times also showed a significant increase in burnout; (b) participants who experienced decreasing resources reported a significant increase in burnout and a significant decrease in engagement; (c) participants who were exposed to chronic low job resources in a highly demanding environment showed a significant increase in burnout; and (d) participants who were exposed to decreased job resources in a highly demanding environment showed a significant increase in burnout.
Failover strategy for fault tolerance in cloud computing environment

Published: April 2017

SummaryCloud fault tolerance is an important issue in cloud computing platforms and applications. In the event of an unexpected system failure or malfunction, a robust fault‐tolerant design may allow the cloud to continue functioning correctly possibly at a reduced level instead of failing completely. To ensure high availability of critical cloud services, the application execution, and hardware performance, various fault‐tolerant techniques exist for building self‐autonomous cloud systems. In comparison with current approaches, this paper proposes a more robust and reliable architecture using optimal checkpointing strategy to ensure high system availability and reduced system task service finish time. Using pass rates and virtualized mechanisms, the proposed smart failover strategy (SFS) scheme uses components such as cloud fault manager, cloud controller, cloud load balancer, and a selection mechanism, providing fault tolerance via redundancy, optimized selection, and checkpointing. In our approach, the cloud fault manager repairs faults generated before the task time deadline is reached, blocking unrecoverable faulty nodes as well as their virtual nodes. This scheme is also able to remove temporary software faults from recoverable faulty nodes, thereby making them available for future request. We argue that the proposed SFS algorithm makes the system highly fault tolerant by considering forward and backward recovery using diverse software tools. Compared with existing approaches, preliminary experiment of the SFS algorithm indicates an increase in pass rates and a consequent decrease in failure rates, showing an overall good performance in task allocations. We present these results using experimental validation tools with comparison with other techniques, laying a foundation for a fully fault‐tolerant infrastructure as a service cloud environment.

Einsatz von multiplen Schwingungstilger‐Systemen an schlanken Fußgängerbrücken
Authors: Meinhardt Christian 
Published: April 2017

AbstractHerrn Univ.‐Prof. em. Dr.‐Ing. Herbert Schmidt zur Vollendung seines 80. Lebensjahres gewidmetDer Einsatz von Schwingungstilgern zur Erhöhung der Gebrauchstauglichkeit von Fußgängerbrücken gehört in der Zwischenzeit zum Standard und erlaubt den Tragwerksplanern die Realisierung filigraner Bauwerke. Im Regelfall wird ein Schwingungstilger zur Reduktion von Schwingungen in einer vertikalen oder lateralen Eigenform eingesetzt, welche in einem kritischen Frequenzbereich, also dem üblichen Bereich der Schrittfrequenzen liegen. Besonders schlanke bzw. leichte Brücken weisen jedoch zahlreiche Eigenformen innerhalb dieses kritischen Bereiches auf, so dass – will man vermeiden, dass je Eigenform in dem kritischen Frequenzbereich ein Tilgersystem appliziert wird – die Konzepte zur Applikation von Schwingungstilgern angepasst werden müssen. Weiterhin weisen schlanke Fußgängerbrücken größere Verschiebungen der Eigenfrequenzen in Abhängigkeit von der Personen‐Anzahl auf dem Brückendeck auf, so dass zusätzlich zu der Wirksamkeit für mehrere Schwingungsmoden auch eine entsprechend große Robustheit des Schwingungstilger‐Konzepts gegenüber diesen Frequenzverschiebungen erforderlich ist. In der Vergangenheit wurden multiple Schwingungstilger‐Systeme vornehmlich mit dem Ziel einer Erhöhung der Wirksamkeit passiver Systeme bei stochastischer Anregung untersucht [1], [2]. Da die dynamische Schwingantwort von schlanken Fußgängerbrücken bei Anregung durch Personen aufgrund der Anregung mehrerer Eigenfrequenzen sowie erzwungener Schwingungen im Bereich der Schrittfrequenz ebenfalls stochastische Züge aufweist, bietet es sich an, solche Konzepte ebenfalls auf Brückendecks zu applizieren. Der folgende Beitrag soll zunächst das typische Schwingungsverhalten schlanker Fußgängerbrücken an praktischen Beispielen demonstrieren. Basierend auf den gezeigten Effekten wird ein für Fußgängerbrücken optimiertes Konzept für Multiple Schwingungstilger (Multiple Tuned Mass Dampers – MTMD)‐Systeme vorgestellt. Hierzu werden die mathematischen Grundlagen zur Optimierung erläutert und Hinweise zur Auswahl abzudeckender Frequenzbereiche sowie zur Massenaufteilung und Abstimmung dargelegt. Abschließend werden Ergebnisse numerischer Berechnungen einer Seilbrückenstruktur vorgestellt, bei denen ein spezielles Augenmerk auf die Robustheit des Systems gegenüber belastungsbedingter Frequenzverschiebungen sowie der charakteristischen Belastung durch Fußgänger gelegt wurde.
