The Paris Agreement sets the target to limit increases in mean global temperature to well below 2C,preferably to 1.5C,compared with preindustrial *** neutrality is the preferred route to reach this target.1 This requires primarily a reduction of CO_(2) emissions to the atmosphere but also an increase of carbon sinks or negative emissions(absorption of atmospheric CO_(2)).The ocean is the largest active carbon pool on Earth,acting as the key regulator to global climate change,and thus has great potential for carbon negative emission.2,3 Recent research demonstrates that the ocean has already absorbed approximately 28%of anthropogenic CO_(2) since the Industrial Revolution,4,5 which indicates that ocean negative carbon emissions could potentially have an important role in achieving the 1.5C or 2.0C *** the urgency and seriousness of the ongoing climate change,it is therefore imperative to explore the potential of enhancing ocean carbon sinks.

The aim of the present study was to investigate the relationship of dynapenia combined with sedentary behavior(SB)on the risk of mortality in older adults living in a Brazilian community.A total of 322 participants aged60 years from the ELSIA(Longitudinal Study of Elderly Health in Alcobaça)prospective cohort were *** was diagnosed when the handgrip strength wasjusted models,the dynapenia and the time spent exposed to SB were analyzed in a combined way,the older adults with worse behavior(high SB and dynapenia)had higher risk ratios for mortality(hazard ratio 2.46;95%confidence interval 1.01–5.97)than the best behavior *** adults with dynapenia are at greater risk for all-cause mortality,which is aggravated by the addition of longer exposure to SB.

We investigated metal-organic vapor phase epitaxy grown(InGa)(AsSb)/GaAs/GaP Stranski–Krastanov quantum dots(QDs)with potential applications in QD-Flash memories by cross-sectional scanning tunneling microscopy(X-STM)and atom probe tomography(APT).The combination of X-STM and APT is a very powerful approach to study semiconductor heterostructures with atomic resolution,which provides detailed structural and compositional information on the *** rather small QDs are found to be of truncated pyramid shape with a very small top facet and occur in our sample with a very high density of∼4×10^(11) cm^(−2).APT experiments revealed that the QDs are GaAs rich with smaller amounts of In and *** element(FE)simulations are performed using structural data from X-STM to calculate the lattice constant and the outward relaxation of the cleaved *** composition of the QDs is estimated by combining the results from X-STM and the FE simulations,yielding∼In_(x)Ga_(1−x)As_(1−y)Sb_(y),where x=0.25–0.30 and y=0.10–***,the reported composition is in good agreement with the experimental results obtained by APT,previous optical,electrical,and theoretical analysis carried out on this material *** confirms that the InGaSb and GaAs layers involved in the QD formation have strongly intermixed.A detailed analysis of the QD capping layer shows the segregation of Sb and In from the QD layer,where both APT and X-STM show that the Sb mainly resides outside the QDs proving that Sb has mainly acted as a surfactant during the dot *** structural and compositional analysis provides a valuable insight into this novel QD system and a path for further growth optimization to improve the storage time of the QD-Flash memory devices.

苏鲁超高压变质带有大量的超镁铁岩体,对这些岩体的成因的研究一直是一个热点。为了鉴别这个地区有无在俯冲进变质前经历过地壳浅部地质过程的超镁铁岩,本文利用BrF5气氛中用CO2红外激光熔样和质谱测试分析方法对中国大陆科学钻探工程主孔内603．20—683．53 m深度的三个石榴单辉橄榄岩样品的单矿物橄榄石、石榴石、单斜辉石的氧同位素进行了分析。橄榄石的δ18O值为+3．31‰-+3．82‰;石榴石的为+4．03‰～+4．10‰;单斜辉石的δ18O值误差较大,平均值为+2．10‰。这些矿物的氧同位素组成总地低于典型的地幔值。研究表明,岩石单矿物低δ18O值是侵入到地壳浅部的超镁铁岩体与寒冷大气降水热液之间的氧同位素交换反应所造成,之后发生了与地壳围岩一齐的俯冲、超高压变质、折返退变质等过程。这是苏鲁地区首次发现的低δ18O值的岩浆侵入型超镁铁岩体,具有重要的大陆动力学意义,从超镁铁岩方面证明了苏鲁地体可能是大别地体的东延部分。

对当前世界上主要的森林火险等级系统进行了综述,包括加拿大、美国、澳大利亚以及其他一些国家的森林火险等级系统。对主要森林火险等级系统的组成、结构和发展过程进行了比较,讨论了这些系统应用的局限性。比较了世界上3个应用比较普遍的森林火险等级系统的发展、可燃物类型、输入因子、输出因子和应用范围,认为发展中国的森林火险等级系统采用加拿大的森林火险等级系统(CFFDRS)的技术比较合适。我们可直接应用CFFDRS,然后根据当地气候和可燃物类型对火险等级系统进行校正。
