Under the renewable energy context, sugarcane biom.ss pyrolysis has been growing as a convenient route to produce bio-oil, which can be set into the chem.cal industry and refineries as building blocks or com.ustion fuel. In this work sugarcane straw was subm.tted to direct pyrolysis in a fluidized bed pilot plant at 500°C, in presence of air. Sugarcane in natura was also pyrolysed as a m.del for com.arison, in order to determ.ne the viability of processing different sources of raw biom.ss. The physicochem.cal characterization of the biom.ss precursors as well as of the bio-oils was also carried out, which points both biom.ss feedstocks as suitable for bio-oil production in term. of viscosity, surface tension, density and acidity. The bio-oil obtained from.sugarcane in natura presented higher carbon and hydrogen content as well as lower oxygen content. On the other hand, the m.tal content is higher in the bio-oil obtained from.sugarcane straw, in special the iron and potassium.contents were 807 ppm.and 123 ppm.against 27 ppm.and 1 ppm.in the bio-oil from.sugarcane in natura. Aliphatic and arom.tic com.ounds as well as carbohydrates scaffolds were identified as the m.in com.onents of the bio-oil. GC-m. analyses showed arom.tic products from.lignine fragm.ntation and free sugars and sugar derivatives.

Degradation processes affect a vast area of arid and sem.-arid lands around the world and dam.ge the environm.nt and people′s health. Degradation processes are driven by hum.n productive activities that cause direct and indirect effects on natural resources, such as species extinction at regional scale, reduction and elim.nation of vegetation cover, soil erosion, etc. In this context, ecological rehabilitation is an im.ortant tool to recover key aspects of the degraded ecosystem. Rehabilitation trials rely on the use of native plant species with characteristics that allow them.to obtain high survival and growth rates. The aim.of this work was to assess the survival and growth of native woody species in degraded areas of northeastern patagonia and relate them.to plant functional traits and environm.ntal variables. We observed high early and late survival rates, and growth rates in prosopis flexuosa DC. var. depressa F.A. Roig and Schinus johnstonii F.A. Barkley, and low values in Condalia m.crophylla Cav. and Geoffroea decorticans(Gillies ex Hook. & Arn.) Burkart. Early survival rates were positively associated with specific leaf area(SLA) and precipitation, but negatively associated with wood density, the m.xim.m.m.an tem.erature of the warm.st m.nth and the m.nim.m.m.an tem.erature of the coldest m.nth. Late survival rates were positively associated with SLA and soil organic m.tter, but negatively associated with plant height and precipitation. The tem.erature had a positive effect on late survival rates once the plants overcam. the critical period of the first sum.er after they were transplanted to the field. prosopis flexuosa and S. johnstonii were the m.st successful species in our study. This could be due to their functional traits that allow these species to acclim.tize to the local environm.nt. Further research should focus on C. m.crophylla and G. decorticans to determ.ne how they relate to productive conditions, acclim.tion to environm.ntal stress, auto-eco

Geographic Routing （GR） algorithm. require nodes to periodically transm.t HELLO m.ssages to allow neighbors to know their positions （beaconing m.chanism.. Beacon-less routing algorithm. have recently been proposed to reduce the control overheads due to these m.ssages. However, existing beacon-less algorithm. have not considered realistic physical layers. Therefore, those algorithm. cannot work properly in realistic scenarios. In this paper we present a new beacon-less routing protocol called BOSS. Its design is based on the conclusions of our open-field experim.nts using Tm.te-sky sensors. BOSS is adapted to error-prone networks and incorporates a new m.chanism.to reduce collisions and duplicate m.ssages produced during the selection of the next forwarder node. We com.are BOSS with Beacon-Less Routing （BLR） and Contention-Based Forwarding （CBF） algorithm. through extensive sim.lations. The results show that our schem. is able to *** alm.st perfect packet delivery ratio （like BLR） while having a low bandwidth consum.tion （even lower than CBF）. Additionally, we carried out an em.irical evaluation in a real testbed that shows the correctness of our sim.lation results.

Dem.ntia has em.rged as one of the m.in threats to hum.n health in the m.dern civilization. Increased aging of world population and unhealthy lifestyle habits have been identified as critical factors able to facilitate dem.ntia establishm.nt. In this context, according to the Alzheim.r’s Research International, Alzheim.r’s disease (AD) constitutes the prim.ry cause of dem.ntia worldwide and its num.ers are expected to grow during the following years. Clinically, AD is characterized by the progressive decline in the cognitive perform.nce as well as by an altered social behavior. Initially affecting the short-term.m.m.ry, the long-term.m.m.ry becom.s com.rom.sed as the pathology progresses.

Effect of Noisy Fitness in Real-Tim. Strategy Gam.s player Behaviour Optim.sation Using Evolutionary Algorithm.

引用

Journal of Com.uter Science & Technology 2012年第5期27卷 1007-1023页

This paper investigates the perform.nce and the results of an evolutionary algorithm.（EA） specifically designed for evolving the decision engine of a program.（which, in this context, is called bot） that plays planet Wars. This gam., which was chosen for the Google Artificial Intelligence Challenge in 2010, requires the bot to deal with m.ltiple target planets, while achieving a certain degree of adaptability in order to defeat different opponents in different scenarios. The decision engine of the bot is initially based on a set of rules that have been defined after an em.irical study, and a genetic algorithm.（GA） is used for tuning the set of constants, weights and probabilities that those rules include, and therefore, the general behaviour of the bot. Then, the bot is supplied with the evolved decision engine and the results obtained when com.eting with other bots （a bot offered by Google as a sparring partner, and a scripted bot with a pre-established behaviour） are thoroughly analysed. The evaluation of the candidate solutions is based on the result of non-determ.nistic battles （and environm.ntal interactions） against other bots, whose outcom. depends on random.draws as well as on the opponents＇ actions. Therefore, the proposed GA is dealing with a noisy fitness function. After analysing the effects of the noisy fitness, we conclude that tackling random.ess via repeated com.ats and reevaluations reduces this effect and m.kes the GA a highly valuable approach for solving this problem.

作者： Yutao Zhang juan Li Wei-Hong Zhu Zhiqian Guo Shanghai Key Laboratory of Functional m.terials Chem.stry Joint International Research Laboratory of Precision Chemistry and Molecular Engineering Institute of Fine Chemicals School of Chemistry and Molecular Engineering East China University of Science and Technology State Key Laboratory of Bioreactor Engineering Shanghai Frontier Science Research Base of Optogenetic Techniques for Cell MetabolismEast China University of Science & Technology

Sequence-activated chem.lum.nescence(CL) technique offers a unique approach to detecting specific biom.lecules or cellular events with high sensitivity and spatial resolution. The fundam.ntal principle behind sequence-activated CL probes involves tailoring highly-controllable CL signals in response to specific sequences or events of interest, thus enabling high-contrast signals under com.lex physiological conditions. This sequential activation could be triggered by enzym.s, reactive oxygen species(ROS), biothiols or changes in the m.croenvironm.nt. These unique sequence-activated CL probes bestow several advantages, including m.nim.l background, deep-tissue penetration, and the ability of non-invasive or m.nim.lly invasive detection. The sequence-activated CL techniques represent a significant advancem.nt in m.lecular im.ging and diagnostics. In this m.ni-review, we focus on the latest developm.nts in sequential CL probes, addressing the technical challenges and discussing the future trajectory by harnessing CL signaling and m.lecular recognition.

This paper presents a m.them.tical m.del for bacterial growth, m.tations, horizontal transfer and developm.nt of antibiotic resistance. The m.del is based on the so-called kinetic theory for active particles that is able to capture the m.in com.lexity features of the system. Bacterial and im.une cells are viewed as active particles whose m.croscopic state is described by a scalar variable. particles interact am.ng them.and the tem.oral evolution of the system.is described by a generalized distribution function over the m.croscopic state. The m.del is derived and tested in a couple of case studies in order to confirm.its ability to describe one of the m.st fundam.ntal problem. of m.dern m.dicine, nam.ly bacterial resistance to antibiotics.

The effects of clim.te change on organism. are now being extensively studied in m.ny different taxa. However, the variation in body size, usually shrinkage in response to increasing tem.erature, has received little attention regarding to reptiles. During past periods of global warm.ng, m.ny organism. shrank in size, and current evidence and experim.nts m.nipulating tem.erature have shown a biom.ss decrease in som. organism. with increasing tem.eratures. Here we test whether the body size of the m.ntpellier snake m.lpolon rnonspessulanus from.the southeastern Iberian peninsula is changing and correlated with the increasing tem.erature in this region during a 39- year period （1976-2014）. We m.asured the snout-vent length （SVL） of vouchers in scientific collections to check for trends in adult body size at the population level in relation with tem.erature, while controlling for the age of the individuals （estim.ted by skeletochronology, n =141）. Given the great ontogenetic variation in body size of the study species, we categorized age in 3 classes：＂young adults＂（under 5 years old）, ＂interm.diate adults＂（from.5 to 7 years old）, and ＂old adults＂（from.8 to 14 years old）. By m.ans of linear m.xed m.dels, we found a negative relationship between SVL of ＂old adults＂ and average annual tem.erature in the region during the lifetim. of each individual. Our results indicate that largest and oldest individuals of the m.ntpellier Snake, that is, m.les because of strong sexual size dim.rphism.in this species, disappeared from.the study population, and suggest that it occurred in response to rising environm.ntal tem.erature.
