作为理解华南构造演化的关键地区,在华南板块南缘的云开地体和越北的Song Chay地体发育了早中生代的向北东逆冲推覆的韧性变形。在云开地体,经历角闪岩相和绿片岩相变质的矿物指示了产状平缓的面理上发育明显的北东一南西向矿物拉伸线理。沿着这些矿物拉伸线理,具有上部指向北东的剪切变形。同位素年代学的定年结果指示了变形事件发生在220 Ma左右。在越南北部,Song Chay地体的岩石和构造特征与云开地体极其相似:平缓的面理,北东一南西向的矿物拉伸线理和上部指向北东的剪切变形是其主要的构造特征,这些构造特征均表现为向北东的逆冲推覆,变形时间从晚三叠世至早侏罗世。这期构造事件的动力学机制被认为同印支板块与华南板块晚古生代一早中生代的构造拼合密切相关。我们认为新发现的Song Chay蛇绿混杂带是华南板块同印支板块的碰撞拼合界线。因此,华南板块南缘云开地体和Song Chay地体被一同卷入同印支板块的碰撞造山体系之中。

AIM: To investigate recruitment, retention, and estimates for effects of formula supplementation with Lactobacillus rhamnosus GG(LGG) on inflammatory biomarkers and fecal microbial community in infants with colic. METHOdS: A prospective, double-blind, placebocontrolled trial was conducted in otherwise healthy infants with colic. We screened 74 infants and randomized and analyzed results in 20 infants [9 receiving LGG(LGG+) and 11 not receiving LGG(LGG-)]. LGG was incorporated in the formula(Nutramigen~®)(minimum of 3 × 107 CFU/d) in the LGG+ group. Fecal microbiota and inflammatory biomarkers, including fecal calprotectin(FC), plasma cytokines, circulating regulatory T cells(Tregs), and crying + fussing time were analyzed to determine optimal time points and effect sizes for a larger trial. RESULTS: Recruitment in this population was slow, with about 66% of eligible infants willing to enroll; subject retention was better(75%). These rates were influenced by parents' reluctance to volunteer their infant for a clinical trial and by their tendency to change formulas. The maximal difference of crying + fussing time was observed at day 14, comparing the 2 groups, with a mean difference of-91(95%CI:-76, 259) min(P = NS). FC showed no significant difference, but the optimal time to determine a potential effect was at day 90 [with a mean difference of 121(95%CI:-48, 291) μg/g stool], observing a lower level of FC in the LGG+ group. The fecal microbial communities were chaotic, as determined by Shannon's diversity index and not apparently influenced by the probiotic. No significant change was observed in plasma inflammatory cytokines or Tregs, comparing LGG+ to LGG- groups. CONCLUSION: designing future colic trials involving a probiotic-supplemented formula for infants in the United States will require consideration for difficult enrollment. Infants with colic have major variations in feal microbiota and calprotectin, both of which improve with time, with optimal time p

An Energy-Efficient Clique-Based Geocast Algorithm for dense Sensor Networks

引用

Communications and Network 2010年第2期2卷 125-133页

作者： Alain Bertrand Bomgni Jean Frédéric Myoupo 不详

This paper proposes an energy-efficient geocast algorithm for wireless sensor networks with guaranteed de-livery of packets from the sink to all nodes located in several geocast regions. Our approach is different from those existing in the literature. We first propose a hybrid clustering scheme: in the first phase we partition the network in cliques using an existing energy-efficient clustering protocol. Next the set of clusterheads of cliques are in their turn partitioned using an energy-efficient hierarchical clustering. Our approach to con-sume less energy falls into the category of energy-efficient clustering algorithm in which the clusterhead is located in the central area of the cluster. Since each cluster is a clique, each sensor is at one hop to the cluster head. This contributes to use less energy for transmission to and from the clusterhead, comparatively to multi hop clustering. Moreover we use the strategy of asleep-awake to minimize energy consumption during extra clique broadcasts.

A deterministic Protocol for Permutation Routing in dense Multi-hop Sensor Networks

引用

Wireless Sensor Network 2010年第4期2卷 293-299页

作者： Alain Bertrand Bomgni Jean Frédéric Myoupo 不详

A large variety of permutation routing protocols in a single-hop Network are known in the literature. Since they are single hop, there is always a wireless link connecting two nodes. One way to solve this problem in a multiple hop environment is to partition nodes into clusters, where a node in each cluster called clusterhead is responsible for the routing service. In this paper, we propose a hybrid clustering mech?anism to perform permutation routing in multi-hop ad hoc Networks. We first propose to partition the network in single-hop clusters also named cliques. Secondly, we run a local permutation routing to broad?cast items to their local destinations in each clique. Next we partition the clusterheads of cliques with the hierarchical clustering technique. We show how the outgoing items can be routed to their destination cliques. We give an estimation of the number of broadcast rounds in the worse case. More precisely, we show that solving the permutation routing problem on a multi-hop sensor network need in the worse case. Where n is the number of the data items stored in the network, p is the number of sensors, |HUBmax| is the number of sensors in the clique of maximum size and k is the number of cliques after the first clustering. Finally, simulation results show that our algorithm performs better than the na?ve multiple gossiping. To the best of our knowledge, it is the first algorithm for permutation routing in multi-hop radio networks.
