Abstract Aim The distribution of mesoplankton communities has been poorly studied at global scale, especially from in situ instruments. This study aims to (1) describe the relation their environment and (2) assess ability various environmental‐based ocean regionalizations explain these communities. Location Global ocean, 0–500 m depth. Time Period 2008–2019. Major Taxa Studied Twenty‐eight grou...

top mutations (formerly supX) eliminate DNA topoisomerase I activity and suppress the leu-500 promoter mutation in Salmonella typhimurium (K. M. Overbye, S. K. Basu, and P. Margolin, Cold Spring Harbor Symp. Quant. Biol. 47:785-791, 1983). Sublethal doses of coumermycin which reduce intracellular levels of supercoiling activity in a top mutant eliminated suppression of the leu-500 mutation. Thi...

Tumor associated macrophages (TAMs) can modify the tumor microenvironment to create a pro-tumor niche. Manipulation of the TAM phenotype is a novel, potential therapeutic approach to engage anticancer immunity. siRNA is a molecular tool for knockdown of specific mRNAs that is tunable in both strength and duration. The use of siRNA to reprogram TAMs to adopt an immunogenic, anti-tumor phenotype ...

This document suggests an X.500 Directory Schema, or Naming Architecture, for use in the COSINE and Internet X.500 pilots. The schema is independent of any specific implementation. As well as indicating support for the standard object classes and attributes, a large number of generally useful object classes and attributes are also defined. An appendix to this document includes a machine process...

The Internet is rapidly becoming the communications infrastructure. With its advantages of speed, availability, and `different time, different place' mode of communication, it can be successfully harnessed to accomplish tasks that previously required face-to-face meetings. Such meetings can consume large travel budgets and staff time, and therefore alternative mechanisms that achieve the same r...

In the words of Lord Kelvin, “if you cannot measure it, you cannot improve it”. One of the longlasting successes of the Top 500 list is sustained, community-wide floating point performance improvement. Emerging large-data problems, either resulting from measured real-world phenomena or as further processing of data generated by simulation, have radically different performance characteristics an...

Interconnect (CI) bus. All Digital's decision stations were to be dual to implement the fiber attachment stations (DASs) distributed data interface and the interconnections (FDDI) physical topology between the stations were with a dual ring of to be wired directly, trees, as opposed to a without patch panels or dual ring only, resulted similar structured wiring in the development of schemes. th...

Intact core tetraether membrane lipids of marine planktonic Crenarchaeota were quantified in water column-suspended particulate matter obtained from four depth intervals ( approximately 70, 500, 1,000 and 1,500 m) at seven stations in the northwestern Arabian Sea to investigate the distribution of the organisms at various depths. Maximum concentrations generally occurred at 500 m, near the top ...
