Many cities have pledged to achieve carbon *** urban water industry can also contribute its share to a carbon-neutral *** a multi-city time-series analysis approach,this study aims to assess the progress and lessons learned from the greenhouse gas(GHG)emissions management of urban water systems in four global cities:Amsterdam,Melbourne,New York City,and *** cities are advanced in setting GHG emissions reduction targets and reporting GHG emissions in their water *** four cities have reduced the GHG emissions in their water industries,compared with those from more than a decade ago(i.e.,the latest three-year moving averages are 13%–32%lower),although the emissions have“rebounded”multiple times over the *** emissions reductions were mainly due to various engineering opportunities such as solar and mini-hydro power generation,biogas valorization,sludge digestion and incineration optimization,and aeration system *** cities have recognized the many challenges in reaching carbon-neutrality goals,which include fluctuating water demand and rainfall,more carbon-intensive flood-prevention and water-supply strategies,meeting new air and water quality standards,and revising GHG emissions accounting *** study has also shown that it is difficult for the water industry to achieve carbon neutrality on its own.A collaborative approach with other sectors is needed when aiming toward the city’s carbon-neutrality *** an approach involves expanding the usual system boundary of the water industry to externally tap into both engineering and non-engineering opportunities.

Coupled quantum molecular cavity optomechanics with surface plasmon enhancement

Photonics Research 2017年第5期5卷 450-456页

作者： JiaN LIU ka-DI ZHU Key Laboratory of Artificial Structures and Quantum Control (Ministry of Education) School of Physics and Astronomy Shanghai Jiao Tong University

Cavity optomechanics is applied to study the coupling behavior of interacting molecules in surface plasmon systems driven by two-color laser beams. Different from the traditional force–distance measurement, due to a resonant frequency shift or a peak splitting on the probe spectrum, we have proposed a convenient method to measure the van der Waals force strength and interaction energy via nonlinear spectroscopy. The minimum force value can reach approximately 10^(-15) N, which is 3 to 4 orders of magnitude smaller than the widely applied atomic force microscope(AFM). It is also shown that two adjacent molecules with similar chemical structures and nearly equal vibrational frequencies can be easily distinguished by the splitting of the transparency peak. Based on this coupled optomechanical system, we also conceptually design a tunable optical switch by van der Waals interaction. Our results will provide new approaches for understanding the complex and dynamic interactions inmolecule–plasmon systems.

An(F)-space E is said to be locally midpoint constricted (in short, Imp-constricted) if there exists some δ>0 such that D(A/2)iameter of A. Our main result goes as follow: Let E be an Imp-constricted (F)-space and U an open connected subset of E. Assume that T:U→F is an isometry (i.e., a distance-preserving map) which maps U onto an open subset of the (F)-space F. Then T can be extended to an affine homeomorphism from E to F. Also, some other results about the question whether each isometry between two (F)-spaces is affine are obtained.

Antibiotic Treatment Drives the Diversification of the Human Gut Resistome

Despite the documented antibiotic-induced disruption of the gut microbiota, the impact of antibiotic intake on strain-level dynamics, evolution of resistance genes, and factors influencing resistance dissemination potential remains poorly understood. To address this gap we analyzed public metagenomic datasets from 24 antibiotic treated subjects and controls, combined with an in-depth prospective functional study with two subjects investigating the bacterial community dynamics based on cultivation-dependent and independent methods. We observed that shortterm antibiotic treatment shifted and diversified the resistome composition, increased the average copy number of antibiotic resistance genes, and altered the dominant strain genotypes in an individual-specific manner. More than 30% of the resistance genes underwent strong differentiation at the single nucleotide level during antibiotic treatment. We found that the increased potential for horizontal gene transfer, due to antibiotic administration, was ～3-fold stronger in the differentiated resistance genes than the non-differentiated ones. This study highlights how antibiotic treatment has individualized impacts on the resistome and strain level composition, and drives the adaptive evolution of the gut microbiota.

Some Remarks on the Meaning and Use of the Tibetan Word bam po

引用

藏学学刊 2009年第1期 114-132页

作者： Leonard W.J.van der Kuijp Department of Sanskrit and Indian Studies Harvard University

This essay seeks to ascertain the various meanings of the word bam po and is mainly a contribution to its lexicography.A study of several treatises in which it occurs suggests that it,and its subordinate unit the shlo ka(ka),were terms that were used to designate various lengths of the textual matter of the earliest translated Buddhist *** a unit of text,a bam po can consist of a varying number of shlo kas. Curiously,both terms also occur in several writings that do not belong to this translated literature but rather to the first indigenous,Tibetan works on *** catalographic terms,bam po and shlo ka are used in the earliest catalogs of titles of translated scripture and indigenous Tibetan literary *** is some evidence that,by fixing the length of a text,they may have been used to prevent unwarranted editorial *** is also some evidence that they played a role in the economy of text *** bam po and the shlo ka were apparently used in connection with calculating the amount of payment translators and scribes should receive for their labors.

针对固定间隙的上海深紫外自由电子激光(SDUV-FEL)混合型波荡器的端部,用Rad ia程序进行了模拟计算。在端部不加任何电磁线圈补偿的情况下,通过减小端部磁铁、磁极的体积和变动端部磁极位置的方法对波荡器磁场进行了优化,优化以后波荡器横向磁场的边缘场强度降到5×10-4T(距离端部磁块边缘10 mm处),边缘场波形没有了明显突起,优化后的横向磁场的一次积分曲线和二次积分曲线都有很大改善,端口处的一次积分值、二次积分值接近于零。
