Thirty years after the downfall of Soviet-led communist bloc, United States-led liberal international order is seen as coming to an end. Policymakers have converged on need safeguard “rules-based order” across newly coined “Indo-Pacific” region. However, policy and scholarly debates lack clarity about what exactly be preserved, why terms rapidly found their way into despite contested meaning. A...

The regional characteristic of China’s agriculture and the present research conditions on regional agriculture have been studied first. After that, a new method is proposed that developing a system for planning regional agricultural advantageous industry development to help leaders and decision-making departments at all levels to make decisions. In order to achieve the construction of a reasoni...

We exploit historical data on planned highways, railroads, and exploration routes as sources of exogenous variation, in order to estimate the effect of interstate highways on regional innovation: a 10% increase in a region?s stock of highways causes a 1.7% increase in regional patenting over a five-year period. In terms of the mechanism, we report evidence that roads facilitate local knowledge ...

Suppose M is a countable first-order structure with a ‘rich’ automorphism group Aut(M). We will study Aut(M) both as a group and as a topological group, where the topology is that of pointwise convergence. This involves a mixture of model theory, group theory, combinatorics, descriptive set theory and topological dynamics. Here, ‘rich’ is undefined and depends on the context, but examples which...

Although conspicuous and well-studied, stag beetles have been slow to join the genomic era. In this study, mitochondrial genomes of two stag beetles, Sinodendron yunnanense and Prosopocoilus confucius, are sequenced for the first time. Both of their genomes consisted of 13 protein-coding genes (PCGs), 22 transfer RNA genes (tRNAs), 2 ribosomal RNAs (rRNAs), and a control region. The mitogenome ...
