Turbo trellis-coded hierarchical modulation assisted decode-and-forward cooperation
No full textHierarchical modulation, which is also known as layered modulation, has been widely adopted across the telecommunication industry. Its strict backward compatibility with single-layer modems and its low complexity facilitate the seamless upgrading of wireless communication services. The potential employment of hierarchical modulation in cooperative communications has the promise of increasing the achievable throughput at a low power consumption. In this paper, we propose a single-relay aided hierarchical modulation based cooperative communication system. The source employs a pair of Turbo Trellis-Coded Modulation schemes relying on specially designed hierarchical modulation, while the relay invokes the Decode-and-Forward protocol. We have analysed the system’s achievable rate as well as its bit error ratio using Monte-Carlo simulations. The results demonstrate that the power consumption of the entire system is reduced to 3.62 dB per time slot by our scheme
Replication Data for: Politicised Enforcement in China: Evidence from the Enforcement of Land Laws and Regulations
No full textPolitically-motivated interference by politicians, or "politicised enforcement", is a common cause of enforcement failure in many countries. Existing research on politicised enforcement has focused largely on incentives driven by electoral competition, while fewer studies analysed its mechanisms in an authoritarian context. Drawing on the case of China, this paper develops the argument that politicised enforcement can be a consequence of the strategies adopted by authoritarian ruling elites to maintain political survival. Using a panel data set on the enforcement of land laws and regulations, the empirical analysis suggests that the intensity of enforcement correlates with economic performance and patron-client ties between central leaders and local officials, suggesting that political imperatives faced by ruling elites to promote economic growth and carry out clientelistic exchanges affect government decisions on enforcement. Moreover, these correlations remain robust after the implementation of reforms that promoted administrative centralisation within the enforcement agency, suggesting that politicised enforcement reflects the strategic behaviour of the ruling elites of the Party. These findings contribute to the literature on enforcement in authoritarian regimes broadly and in China specifically

Climate and edaphic factors drive soil nematode diversity and community composition in urban ecosystems
No full textRapid urbanization profoundly affects global biodiversity. How urbanization modifies soil biodiversity and perturbs nematodes remains limited. Here, we investigated soil nematodes in four land-use types: Parks, residential areas, natural forests, and maize fields across 12 cities in China. Urban parks and surrounding forests had similar nematode richness exceeding that in urban residential areas and surrounding farmlands. Nematode
communities in parks and residential areas were, however, more homogenous than in forests and farmlands. Variations in nematode assemblages in both core urban and urban surroundings were mainly due to taxa replacement, indicating that nematodes were spatially isolated in cities. Urban residential areas were colonized by the lowest number of specialists (i.e., with narrow niche width) and smaller body sizes. Urban parks, conversely, served as hotspots for soil nematodes in cities. Together, our results indicate that urbanization processes reduce nematode diversity, with e.g., 30% loss in residential areas compared to forests, and homogenize soil nematode communities
