Decentralized control of network‐based interconnected systems: A state‐dependent triggering method
Authors: Tian Engang , Yue Dong 
Published: December 2013

SummaryThis paper investigates decentralized control for a class of interconnected system. Different from the traditional systems, the considered system has the following features: (i) its subsystems are connected through a communication network subject to transmission delays and packet losses; (ii) the subsystems' multi‐actuators are subjected to random faults; and (iii) the subsystems are subject to probabilistic nonlinear disturbances, the inner variation information of the nonlinearities, as well as their bounds information, is utilized to analyze the nonlinearities. Furthermore, in order to reduce the network bandwidth burden, a decentralized state‐dependent triggering scheme is proposed. Considering aforementioned characteristics and using the state‐dependent triggering scheme, new type of network‐based interconnected system model is built. By using the Lyapunov functional approach, sufficient conditions for the mean square stability and stabilization of the network‐based interconnected systems are obtained. Then reliable controllers, as well as the triggering matrices of the local subsystems, can be co‐designed by using a cone complementary linearization algorithm. Two simulation examples are given to illustrate the effectiveness and application of the proposed method. Copyright © 2013 John Wiley & Sons, Ltd.

AbstractThe forest canopy cover can directly and indirectly affect soil conditions and hence soil carbon emission through soil respiration. Little is known, however, on the effects of canopy cover on soil respiration under the canopy of different tree species and soil water conditions. We have examined the variation in soil respiration at different soil water conditions (dry <10 %, wet >20 %, v/v) under different tree canopy covers in comparison with the canopy interspace in a temperate coniferous (Pinus armandii Franch) and broadleaved (Quercus aliena var. acuteserrata) mixed forest in central China. The results show that soil respiration measured under tree canopy cover varied with canopy size and soil water content. Soil respiration under small‐sized canopies of P. armandii (PS) was higher than that under large‐sized (PL) canopies, but the difference was only significant under the dry soil condition. However, soil respiration under large‐sized canopies of Q. aliena (QL) was significantly greater than that under small‐sized (QS) canopies under both dry and wet soil conditions. The difference in soil respiration between differently sized canopies of Q. aliena (33.5–35.8 %) was significantly greater than that between differently sized canopies of P. armandii (2.4–8.1 %). Differences in soil respiration between inter‐plant gaps and under QS canopies in both the dry and wet soil conditions were significant. Significant increases in soil respiration (9.7–32.2 %) during the transition from dry to wet conditions were found regardless of canopy size, but the increase of soil respiration was significantly lower under P. armandii canopies (9.7–17.7 %) than under Q. aliena canopies (25.9–31.5 %). Our findings that the canopy cover of different tree species influences soil respiration under different soil moisture conditions could provide useful information for parameterizing and/or calibrating carbon flux models, especially for spatially explicit carbon models.

Abstract

Objective

We assessed the value of combining 123I-IMP brain perfusion SPECT and 123I-MIBG myocardial scintigraphy for the discrimination of dementia with Lewy bodies (DLB) from other types of dementia.

Methods
We subjected 252 consecutive patients with clinically suspected DLB to both 123I-IMP brain perfusion SPECT and 123I-MIBG myocardial scintigraphy. Patients with Parkinson’s disease were included. The 252 patients were randomly assigned to an estimation (n = 152) or a validation group (n = 100). Using univariate analysis, we first analyzed the relationship between various variables and the presence or absence of DLB in estimation group and then proceeded to multivariate analysis to obtain a combined index that predicted the likelihood of DLB. The diagnostic value of the index was assessed by calculating the area under the receiver operating characteristic (ROC) curve (AUC) with the cutoff value selected from the ROC curve. We then tested the predictive accuracy of the index in validation group.

Results
The combined index was an arithmetic expression that combined the age, early 123I-MIBG heart-to-mediastinum uptake (E-H/M) ratio, and the parietal lobe hypoperfusion score. Values for the AUC of the combined index, the E-H/M ratio, the parietal lobe hypoperfusion score, and the patient age in validation group were 0.95, 0.90, 0.72, and 0.73, respectively. There was a significant difference in the AUC of the combined index among other indices (p < 0.05). The sensitivity, specificity, and accuracy of the combined index for a diagnosis of probable DLB in validation group were 88, 87, and 87 %, respectively.

Conclusions
The combinational diagnosis based on 123I-IMP brain perfusion SPECT, 123I-MIBG myocardial scintigraphy, and the patient age is a simple and reliable means for predicting probable DLB.
Tokapal Tuff-facies Kimberlite, Bastar Craton, Central India: A Nickel Prospect?

Published: December 2013

Abstract
We report the occurrence of garnierite (a general term referring to Ni-Mg bearing hydrous silicates in laterites) from the crater-facies Tokapal kimberlite of the Bastar craton, Central India. Garnierite occurs as discrete ovoid or amoeboid segregations (up to 200 mm) or as veinlets with up to 18.1 wt% NiO and high iron contents (up to 36.2 wt% FeOT). Chemical composition of the garnierite implies its derivation from a magnesium-rich protolith. Extensive lateritisation of the large crater-facies (∼2.5 km diameter) saucer-shaped kimberlite under tropical weathering conditions, aided by suitable topography, drainage and favourable structural set-up, are the factors inferred to be responsible for the formation of garnierite in the Tokapal system. As lateritic nickel ores constitute significant resources for nickel exploration, the perspective of the Tokapal kimberlite as a nickel prospect needs to be investigated.
Chronology of Late Quaternary Glaciations in Indian Himalaya: A Critical Review
Authors: Ali S. Nawaz , Juyal Navin 
Published: December 2013

Abstract
The timing of glaciation is an important parameter that helps in the understanding of past climate change and provides valuable information for developing the predictive futuristic models. There are evidences to suggest that during the late Quaternary, Himalayan glaciers fluctuated considerably thus implying their sensitivity to changes in past climatic conditions. Although the Himalayan region is fed by two major weather systems viz. the southwest summer monsoon and the mid-latitude westerlies, however, the existing chronology (mostly exposure ages) indicates that irrespective of the geographical position, glaciers seem to grow during increased insolation and enhanced southwest summer monsoon including the mid-latitude westerly dominated north-western Himalayan glaciers (Ladakh and Karakoram). Considering the limited geographical coverage and the dating uncertainty, the above inferences should be treated as tentative.

Abstract
Hanjiang river is the longest river in Yangtze river basin, having high economic importance to China for its economically exploitable hydropower and potential water resources. In an attempt to satisfy China’s economic and social development needs, the Chinese government has established cascade dams and four relative water diversion projects in Hanjiang river, which aims at transferring water from south (Hanjiang river) to north (water-stricken areas). However, there are increasing eco-environmental concerns associated with the establishment and development of cascade hydropower. In this study, the opportunities and eco-environmental influences related to Hanjiang river’s cascade hydropower development are explored and then recommendations are put forward to minimize the potential impacts. The implementation of vigorous projects related to hydropower and water diversion has an important role to play in solving flood, energy and water shortage problems. In addition, the eco-environmental and socio-economic impacts on the middle and downstream and its diversion can be relieved to some degree in the area. However, the establishment of projects can cause several impacts on the local eco-environment. First, Danjiangkou reservoir construction can cause change in water flow, water bloom, soil erosion in the river basin. Second, it can directly lead to the decrease of 10.5 billion cubic meters of water in the middle- and downstream areas, threatening the local supply of drinking water and influencing farming irrigation and industrial production. Finally, the construction of cascade hydropower dams can change the water form and fish stocks may reduce threatening eco-environment security and environmental geology.

Abstract
The Tirgan Formation (Barremian – Aptian) is exposed in the Kopet Dagh in northeast Iran. Two stratigraphic sections in Radkan and Chenaran were measured. Their thickness are 238 m and 119 m, respectively. This formation in measured sections consists of three parts (including lower carbonate, middle limy shale – marl and upper carbonate rocks). Based on study of 164 thin-sections, 15 carbonate and 2 siliciclastic lithofacies have been identified. Carbonate lithofacies are deposited in a ramp platform in fore shoal, shoal, lagoon and tidal flat environments. Sea level changes during lower Cretaceous led to the formation of different large-scale depositional sequences Radkan (two) and Chenaran (two) respectively. The present study highlights the reconstruction of tectonic history of the area during lower Cretaceous.
Likelihoods for fixed rank nomination networks
Authors: HOFF PETER , FOSDICK BAILEY , VOLFOVSKY ALEX , STOVEL KATHERINE 
Published: December 2013

AbstractMany studies that gather social network data use survey methods that lead to censored, missing, or otherwise incomplete information. For example, the popular fixed rank nomination (FRN) scheme, often used in studies of schools and businesses, asks study participants to nominate and rank at most a small number of contacts or friends, leaving the existence of other relations uncertain. However, most statistical models are formulated in terms of completely observed binary networks. Statistical analyses of FRN data with such models ignore the censored and ranked nature of the data and could potentially result in misleading statistical inference. To investigate this possibility, we compare Bayesian parameter estimates obtained from a likelihood for complete binary networks with those obtained from likelihoods that are derived from the FRN scheme, and therefore accommodate the ranked and censored nature of the data. We show analytically and via simulation that the binary likelihood can provide misleading inference, particularly for certain model parameters that relate network ties to characteristics of individuals and pairs of individuals. We also compare these different likelihoods in a data analysis of several adolescent social networks. For some of these networks, the parameter estimates from the binary and FRN likelihoods lead to different conclusions, indicating the importance of analyzing FRN data with a method that accounts for the FRN survey design.

AbstractThe tachinid flyExorista larvarum(L.) (Diptera: Tachinidae) is a polyphagous larval endoparasitoid that deposits its eggs on the host exoskeleton of lepidopteran and tenthredinid larvae. The attachment of larvalE. larvarumand the formation of the respiratory funnel were studied during infestation in the last larval instar of the wax moth,Galleria mellonella(L.) (Lepidoptera: Pyralidae). The tachinid larvae burrow through the host integument after hatching, using their robust cephalopharyngeal skeleton, leaving a dark spot at the point of their penetration as a result of host cuticle melanization. Endoparasitoid penetration induces the host cellular defence, resulting in the formation of a haemocyte capsule consisting of multi-cellular sheaths. This enveloping capsule later undergoes melanization, which is mostly obvious towards the posterior part of the endoparasitoid. The endoparasitoid uses the host encapsulation response to build a respiratory funnel from the modified host integument, leading to the host surface. The encapsulated larva remains attached to the respiratory funnel via an anal hook and cuticular spines until fully developed. Additional immunohistochemical analyses were used to study host–parasitoid interactions. Indirect immunofluorescence showed no labelling of potential tachinid antigens and confirmed no effect on the surrounding host tissues. A simulated parasitization with coated polybead microspheres revealed the mortal impact of tachinid antigens to the host. Hosts injected with antigen-coated polybeads died as a consequence of an acute and extensive immunological response to the tachinid antigens and not due to the trauma caused by foreign objects inside their body.

AbstractObjective:Three-dimensional fluid-attenuated inversion recovery magnetic resonance imaging of the inner ear after intratympanic injection of gadolinium, together with magnetic resonance imaging scoring of the perilymphatic space, were used to investigate the positive identification rate of hydrops and determine the technique's diagnostic value for delayed endolymphatic hydrops.Methods:Twenty-five patients with delayed endolymphatic hydrops underwent pure tone audiometry, bithermal caloric testing, vestibular-evoked myogenic potential testing and three-dimensional magnetic resonance imaging of the inner ear after bilateral intratympanic injection of gadolinium. The perilymphatic space of the scanned images was analysed to investigate the positive identification rate of endolymphatic hydrops.Results:According to the magnetic resonance imaging scoring of the perilymphatic space and the diagnostic standard, 84 per cent of the patients examined had endolymphatic hydrops. In comparison, the positive identification rates for vestibular-evoked myogenic potential and bithermal caloric testing were 52 per cent and 72 per cent respectively.Conclusion:Three-dimensional magnetic resonance imaging after intratympanic injection of gadolinium is valuable in the diagnosis of delayed endolymphatic hydrops and its classification. The perilymphatic space scoring system improved the diagnostic accuracy of magnetic resonance imaging.
Support from below? Supranational institutions, regional élites and governance preferences
Authors: Tatham Michaël , Bauer Michael W. 
Published: December 2013

AbstractThere has been little research on élite preferences regarding supranational integration. Regional élites have been particularly neglected, even though they are implementers of European policies and programmes and therefore contribute to the integration process. To bridge this gap, this article explores the preferences of top regional civil servants – regio-crats – towards one of the most prominent supranational institutions, the European Commission. We put five explanations to the test. Support in favour of a stronger, more autonomous Commission can be driven by (1) pragmatic inter-institutional alliances, (2) the domestic distribution of power, (3) benefits derived from the integration process itself, (4) identity and identification elements and (5) transactionalism. We find support for three of these explanations as inter-institutional relations, perceived benefits and region-specific identity characteristics contribute to and account for regio-crat preferences. This resonates with interest- versus value-based approaches to European Union (EU) integration and contributes towards a better understanding of the dynamics at play in integrating multi-jurisdictional polities, of which the EU is an example.
Picket lines and parades: labour and urban space in early twentieth-century London and Chicago
Authors: PERCY RUTH 
Published: December 2013

ABSTRACTGarment strikes in London and Chicago provide a setting to consider the role of the city in early twentieth-century labour struggles. While strikers in the two cities shared similar experiences and confronted similar imaginings of the city, they faced different built environments. The comparative approach thus highlights the importance of considering spatial dynamics when studying strikers’ strategies. Journalists’ and other onlookers’ responses to picket lines, parades or mass meetings reflected normative understandings and expectations of workers’ behaviour, especially if those workers were young, women or ethnic minorities. The article considers the ways in which strikers in early twentieth-century London and Chicago transgressed contemporary perceptions of their cities by appropriating city space and by subverting behavioural norms in spaces where they did belong. I argue that the strikers drew attention to their struggles via their atypical use of the city streets and that occupying these spaces helped unify the strikers and thus strengthen the strike.

Published: December 2013

SummaryThe aim of the present study was to examine the effects of brilliant cresyl blue (BCB) staining on mitochondrial functions in porcine oocytes. Cumulus–oocyte complexes (COCs) collected from slaughterhouse-derived porcine ovaries were cultured with (13 μM) or without (0 μM, control) BCB for 60 min. Mitochondrial functions in oocytes were examined immediately after staining or after in vitro maturation. The BCB-stained oocytes produced reactive oxygen species (ROS) at higher levels than control oocytes immediately after staining (2.2-fold, P < 0.001) and after maturation (1.7-fold, P < 0.001). The adenosine triphosphate (ATP) content and mitochondrial membrane potential (MMP) in oocytes were similar for the two groups immediately after staining. However, ATP and relative MMP levels were significantly (P < 0.05) lower in BCB-treated oocytes than in the control (2.18 versus 2.83 pM and 0.82 versus 1.0, respectively). There was no difference in mitochondrial DNA copy number between the two groups after maturation. The ATP content in early developmental stage embryos (3 days after parthenogenetic activation) was lower in the BCB-stained group than that in the control group but the difference was not significant. In conclusion, BCB staining of oocytes at the immature stage compromises mitochondrial functions throughout oocyte maturation, but function is restored during early embryo development.

AbstractObjectiveTo investigate vitamin D status and its association with components of the metabolic syndrome (MetS) in adolescent girls attending high school in Boukan, Iran during winter 2012.DesignA cross-sectional study.SettingHigh schools of Boukan city, Iran.SubjectsA sample of 216 girls aged 14–17 years was selected by multistage random sampling from four districts of Boukan. Weight, height, waist circumference, blood pressure, daily energy intake, physical activity and serum 25-hydroxyvitamin D (25(OH)D), fasting blood glucose, TAG and HDL-cholesterol levels of all participants were evaluated. Serum 25(OH)D level <20 ng/ml was defined as vitamin D deficiency.ResultsMean serum 25(OH)D was 7·26 (sd2·81) ng/ml and 96 % of the participants had vitamin D deficiency. According to age-modified definitions of the National Cholesterol Education Program Adult Treatment Panel III, MetS was diagnosed in 10·6 % of the participants. In multivariable regression analysis after adjustment for BMI, energy intake and physical activity level, serum 25(OH)D was inversely associated with fasting blood glucose (β= −0·143,P= 0·04). No significant relationship was found between serum 25(OH)D and other components of MetS.ConclusionsThe high prevalence of vitamin D deficiency warrants national polices and interventions towards improving this major health problem among adolescent girls. Low 25(OH)D level was significantly associated with increased fasting blood glucose. Prospective studies are needed to determine the effects of vitamin D deficiency on the development of MetS and related metabolic diseases in adolescent girls.

Published: December 2013

AbstractThe complex behavior of financial markets emerges from decisions made by many traders. Here, we exploit a large corpus of daily print issues of the Financial Times from 2nd January 2007 until 31st December 2012 to quantify the relationship between decisions taken in financial markets and developments in financial news. We find a positive correlation between the daily number of mentions of a company in the Financial Times and the daily transaction volume of a company's stock both on the day before the news is released and on the same day as the news is released. Our results provide quantitative support for the suggestion that movements in financial markets and movements in financial news are intrinsically interlinked.
