In the traditional distributed consensus of multi-vehicle systems, vehicles agree on velocity and position using limited information exchange in their local neighborhoods. Recently, distributed leaderless stationary consensus has been proposed in which vehicles agree on a position and come to a stop. The proposed stationary consensus schemes are based on all vehicles＇ access to their own absolute velocity measurements, and they do not guarantee this collective behavior in the presence of disturbances that persistently excite vehicles＇ dynamics. On the other hand, traditional distributed disturbance rejection leaderless consensus algorithms may result in an uncontrolled increase in the speed of multi-vehicle system. In this paper, we propose a dynamic relative-output feedback leaderless stationary algorithm in which only a few vehicles have access to their absolute measurements. We systematically design the distributed algorithm by transforming this problem into a static feedback robust control design challenge for the low-order modified model of vehicles with fictitious modeling uncertainties. We further propose dynamic leader-follower stationary consensus algorithms for multi-vehicle systems with a static leader, and find closed-form solutions for the consensus gains based on design matrices and communication graph topology. Finally, we verify the feasibility of these ideas through simulation studies.

Mus cypriaeus is a recently discovered endemic species that evolved about half a million years ago on the Cyprus Is- land in an absence of most mammalian predators and competitors. As on other Mediterranean islands, the faunal composition was dramatically changed by the invasion of commensal and domestic species following Holocene colonization by humans. We exa- mined the behavioral responses of the Cypriot mouse to the odors of these new competitors （black and Norway rat, house mouse and spiny-mouse） and predator （domestic cat） as well as controls （Herb-field mouse, guinea pig）. We compared them with those of mainland population of house mouse from Syria with different coexistence history. Surprisingly, the Cypriot mouse failed to avoid the odor of its current main competitor, the black rat. Moreover, the response patterns of both the Cypriot and Syrian house mice to the examined odor sources appeared fairly comparable. There was a clear tendency to prefer odors of other murids over unscented sawdust as well as to avoid the odor of a domestic cat. In conclusion, neither the long-term isolation from predators nor the recent strong competition with black rats affected mice eompetitory and antipredatory responses fundamentally [Current Zoology 61 （4）： 781-791, 2015].

Objectives To investigate the effect of Burn Healing Liquid (BHL) on the proliferation of keratinocytes and fibroblasts and to explore the potential effect of BHL on fibroblast contraction Methods Human keratinocytes and dermal fibroblasts were cultured in media containing serial dilutions of BHL followed by cell proliferation determination assessed with MTT (3 [4,5 dimehtylthiazol 2 yl] 2,5 diphenyl tetrazolium bromide) assay at different time intervals The in vitro collagen lattice contraction model was utilized for determining the contractility of fibroblasts cultured in BHL containing medium Results The 1∶10 7 dilution of BHL enhanced the growth of both keratinocytes and fibroblasts whereas the 1∶10 dilution increased the growth of keratinocytes only Collagen lattice contraction was inhibited dose dependently by BHL and such an inhibition could be reversed by switching BHL containing medium to normal medium containing 10% fetal calf serum Conclusion BHL enhances the growth of both keratinocytes and fibroblasts and reversibly inhibits the fibroblast contraction in collagen lattice

作者： margareta Wilsson Annsofie Adolfsson 不详

One of the main priorities of the child healthcare services in Sweden is a home visit by the Child Health Care (BVC) nurse to newborn babies and their parents. It is essential that the BVC nurses have a comprehensive knowledge of the parent’s need of support and their expectations as new parents in order to be able to fulfill their needs. The aim of this study was to describe what type of support the mothers of infant children are in need of and what their expectations are of the BVC nurse when it is time for the home visit from the nurse. In this qualitative study twelve women were interviewed within one to two weeks after delivering a baby. The transcripts were analyzed using qualitative content analysis. The study shows that mothers who have previously given birth to children feel more secure in their parental role compared to what they experienced as first time mothers. The findings include that first time mother’s experienced uncertainty in their new role as a mother and caring for a baby. Parents seek support from the BVC nurse and they expect her behavior and attitude towards them to be friendly and professional. The fact that she is privy to personal knowledge of the family gives the parents a feeling of security when they contact the child healthcare center for various reasons. The mother’s need for support to develop as a parent and to feel secure in the parental role was a reoccurring theme in the interviews and became the theme of the study.
