The arrangement of functionally-related genes in operons is a fundamental element of how genetic information is organized in prokaryotes. This organization ensures coordinated gene expression by co-transcription. Often, however, alternative genetic responses to specific stress conditions demand the discoordination of operon expression. During cold temperature stress, accumulation of the gene encoding the sole Asp–Glu–Ala–Asp (DEAD)-box RNA helicase in Synechocystis sp. PCC 6803, crhR (slr0083), increases 15-fold. Here, we show that crhR is expressed from a dicistronic operon with the methylthiotransferase rimO/miaB (slr0082) gene, followed by rapid processing of the operon transcript into two monocistronic mRNAs. This cleavage event is required for and results in destabilization of the rimO transcript. Results from secondary structure modeling and analysis of RNase E cleavage of the rimO–crhR transcript in vitro suggested that CrhR plays a role in enhancing the rate of the processing in an auto-regulatory manner. Moreover, two putative small RNAs are generated from additional processing, degradation, or both of the rimO transcript. These results suggest a role for the bacterial RNA helicase CrhR in RNase E-dependent mRNA processing in Synechocystis and expand the known range of organisms possessing small RNAs derived from processing of mRNA transcripts.

Publication Date: Apr 10 2020 The SEC will withdraw the existing approval order and the fund will become subject to the requirements of Rule 6c-11 and Nasdaq Rule 5704....

Publication Date: Apr 10 2020 Yes. According to the SEC, once an ETF becomes eligible to operate under Rule 6c-11 and elects to list on Nasdaq under Nasdaq Rule 5704, the existing order related to that fund (and all other funds under that exemptive order) will be rescinded. Once a fund is listed under Nasdaq Rule 5704, it will not be able to relist under Nasdaq Rule 5705(b) (Index Fund Shares) or Nasdaq Rule 5735 (Managed Fund Shares) unless a new exemptive relief order is obtained from the SEC....

Publication Date: Apr 10 2020 On or before December 22, 2020, all ETFs that meet the definition of "Exchange Traded Fund" in Nasdaq Rule 5704(a)(1)(A) will need to be compliant with Rule 6c-11. If it is determined that an ETF no longer complies with Rule 6c-11 and therefore no longer complies Nasdaq Rule 5704, Nasdaq will generally issue a letter of deficiency. The ETF will generally be given 45 days to submit a plan to regain compliance. If the plan is accepted, Nasdaq Staff can grant an...

The current dispute between the US and China goes far beyond trade tariffs and tit-for-tat reprisals: the underlying driver is a race for global technological supremacy. This paper examines the risks of greater strategic competition as well as potential solutions for mitigating the impacts of the US–China economic confrontation.

The music of most hit songs is pretty well known, but sometimes there are mysteries. One question that remained unanswered for over forty years is: What instrumentation and notes make up the opening chord of the Beatles. "A Hard Day.s Night"? Mathematician Jason Brown - a big Beatles fan - recently solved the puzzle using his musical knowledge and discrete Fourier transforms, mathematical transformations that help decompose signals into their basic parts. These transformations simplify applications ranging from signal processing to multiplying large numbers, so that a researcher doesn.t have to be "working like a dog" to get an answer. Brown is also using mathematics, specifically graph theory, to discover who wrote "In My Life," which both Lennon and McCartney claimed to have written. In his graphs, chords are represented by points that are connected when one chord immediately follows another. When all songs with known authorship are diagrammed, Brown will see which collection of graphs - McCartney.s or Lennon.s - is a better fit for "In My Life." Although it may seem a bit counterintuitive to use mathematics to learn more about a revolutionary band, these analytical methods identify and uncover compositional principles inherent in some of the best Beatles. music. Thus it.s completely natural and rewarding to apply mathematics to the Fab 4 For More Information: Professor Uses Mathematics to Decode Beatles Tunes, "The Wall Street Journal", January 30, 2009..

Dear Shareholders, As Chairwoman of the Supervisory Board, I am contacting you personally today in advance of the Annual General Meeting to ask for your continued trust and support.

euromicron AG, a medium-sized technology group and specialist for the digital support of business processes through secure infrastructures, is pooling its digital expertise at KORAMIS GmbH, the group subsidiary that specializes in cyber security and automation. With focus on digital platforms and services KORAMIS’ portfolio will also cover the areas Smart IoT, Smart Building as well as Data Management in the future. For this step the management of KORAMIS GmbH was extended by Andreas Schmidt.

euromicron AG, a medium-sized technology group and expert on digital networking of business and production processes, held its Annual General Meeting 2019 in Frankfurt/Main on August 29, 2019. 42 percent of the share capital was represented. At the Annual General Meeting, the Executive Board reported on the operating performance in fiscal year 2018 and in the first half of 2019 and gave an outlook on the current fiscal year. One focus was on the implementation of the measures initiated to focus on and further develop the business model.

Water scarcity, a socio-environmental threat to anthropogenic activities and ecosystems alike, affects large regions of the globe. However, it is often the most vulnerable and disadvantaged populations that suffer the severest consequences, highlighting the role of economic and institutional factors in water scarcity. In this way, researchers generally consider not only the physical constraints but socio-economic determinants as well.

Rampant deforestation, uncontrolled expansion of agriculture, infrastructure development and exploitation of wild species have created a 'perfect storm' for the spillover of diseases from wildlife to people.

In these unusual and tragic times, I am indeed grateful that we are able to connect virtually to continue the business of environmental governance. While the efforts of all your capitals are correctly focused on preventing human suffering, as parts of the world move slowly towards recovery, the environmental agenda remains one of our most powerful insurance policies in preventing future global pandemics like COVID-19.

Tropical rainforests are the world's richest land habitats for biodiversity, harbouring stunning numbers of plant and animal species. The Amazon and the Congo basins, together with Asian rainforests, represent only 6 per cent of earth's land surface, and yet more than 50 per cent of global biodiversity can be found under their shade.
