Abstract Developing low-carbon economy is an inherent requirement for China's sustainable development, and digital important engine to reduce carbon emission intensity in the new development stage. Identifying industrial evolution law of helpful diagnose its opportunity, tap "green potential", provide strategic support play effect. Based on data industrialization industry digitization from 2001...

The polyether antibiotics reported by the year 1968 were nigericin1) (X-4642)), lasalocid (X-537A2)), X-2062), dianemycin3) and monensin4). Monensin (1) was the only one whose structure was known at that time. In the following decade, the number of distinct polyethers increased from these five to forty-six, almost all of which were structurally assigned. As a result of this rapid growth, a numb...

We have made the first direct interferometric proper motion measurements of the radio pulsar B1757−24, which sits at the tip of the " beak " of the putative " Duck " supernova remnant. The peculiar morphology of this radio complex has been used to argue alternately that the pulsar's space motion was either surprisingly high or surprisingly low. In fact, we show that the pulsar's motion is so sm...
