Consensus Control in Linear Multi‐Agent Systems with Current and Sampled Partial Relative States
Authors: Xin Youming , Cheng Zunshui 
Published: September 2013

ABSTRACTThis paper studies consensus in linear multi‐agent systems with current and sampled partial relative states. A distributed linear consensus protocol is designed, where both current and sampled relative states are utilized. A necessary and sufficient condition for consensus in this setting is established. The notion of the consensus region is then introduced and analyzed for third‐order systems, provided that each agent can only know its relative positions and velocities. It is shown that the consensus regions are stable to control gains and sampling period. Additionally, how to choose the control gains and the sampling period is given for consensus in third‐order systems. Finally, an example is given to verify and illustrate the analysis.
‘The Good Mother and Her Clinging Child’: Patterns of Anchoring in Social Representations of Dementia Caregiving
Authors: Toepfer Nils F. , Foster Juliet L. H. , Wilz Gabriele 
Published: September 2013

ABSTRACTThis paper discusses the findings of a study that examined the processes of anchoring in the understanding of dementia caregiving using 29 interviews conducted in Germany with wives and daughters caring for a relative with dementia and 43 newspaper articles pertinent to the research objective. The concept of anchoring from Social Representations Theory was complemented by elements from cognitive linguistics to analyse the social representations (SRs) that served as source domains to determine what the target domain of dementia caregiving means, entails and requires. The analysis revealed three prevalent patterns of anchoring dementia care in SRs of child care and the good mother. The first pattern ascribed the role of the helpless clinging child needing his mother to the dementia patient, the second emphasised that the dementia caregivers' responsibility for caring, just like motherhood, should take precedence over all other interests and the third consisted of dementia caregivers deriving the perception of being the most suitable caregiver from the mother's natural aptitude for caring. The conclusions reached by the different patterns are argued to contribute to dementia caregivers overexerting themselves and not using support services. The clinical implications for targeting such adverse effects of the anchoring will be discussed. Copyright © 2013 John Wiley & Sons, Ltd.
Three‐Dimensional Macroporous NiCo2O4 Sheets as a Non‐Noble Catalyst for Efficient Oxygen Reduction Reactions
Authors: Xiao Ying , Hu Chuangang , Qu Liangti , Hu Changwen , Cao Minhua 
Published: September 2013

AbstractA facile and low‐cost strategy is developed to prepare three‐dimensional (3D) macroporous NiCo2O4 sheets, which can be used as a highly efficient non‐noble metal electrocatalyst for the oxygen reduction reaction (ORR) in alkaline conditions. The as‐obtained sheets have a thickness of about 150 nm and feature a typical 3D macroporous structure with pore volumes of up to 0.23 cm3 g−1, which could decrease the mass transport resistance and allow easier access of the reactants to the active surface sites. The as‐prepared macroporous NiCo2O4 sheets exhibit high electrocatalytic activity for ORR with a four‐electron pathway, good long‐term stability and high tolerance against methanol. The unique 3D macroporous structure and intrinsic properties may be responsible for their high performance.
Carcinogenic Organic Residual Compounds Readsorbed on Thermally Reduced Graphene Materials are Released at Low Temperature

Published: September 2013

AbstractThe preliminary oxidation of graphite to graphite oxide followed by a thermal exfoliation is one of the methods most frequently employed in the preparation of graphene. Such thermally reduced graphene can be widely used for several applications that range from coatings to sensing device fabrication. It is therefore important to investigate in detail the fabrication procedure, the structural features of the resulting graphene, and its potential toxicological effects. Low‐molecular‐weight and carcinogenic compounds are known to be generated during the thermal reduction/exfoliation of graphite oxide. Such compounds are readsorbed onto the reduced material during the cooling process. We investigate here the composition of the organic compounds that are adsorbed onto the graphene material and show that they can be easily released during the following processing steps even at temperatures as low as 50 °C. Some of the released organic compounds are classified as highly carcinogenic. The results shown here are important not only from a chemical point of view to better understand the composition and properties of the graphene material produced, but also to bring attention to the potential toxicological effects that the synthesis itself or the post‐production processes can cause.
