Statistical methods for network data often parameterize the edge-probability by attributing latent traits such as block structure to the vertices and assume exchangeability in the sense of the Aldous-Hoover representation theorem. These assumptions are however incompatible with traits found in real-world networks such as a power-law degree-distribution. Recently, Caron & Fox (2014) proposed the...
Dr Nair’s letter to the editor regarding the failed nerve blocks mentioned in our paper, “Comparison of the supraclavicular, infraclavicular and axillary approaches for ultrasound-guided brachial plexus block for surgical anesthesia”,1 raised several points that I believe are worth looking at in more detail. We are grateful for Dr Nair’s comments which have contributed to the furthering of scho...
High quality hex mesh can be effectively generated based on the block structure of a solid model, but the existing approaches to block decomposition of the solid model are still far from the expectation. In this paper, we propose a new method of decomposing the solid model into the block structure based on sheet operations, which can guarantee the validity of the resultant block structure. The ...
In this paper, we propose a new symmetric key block cipher SC2000 with 128-bit block length and 128-,192-,256-bit key lengths. The block cipher is constructed by piling two layers: one is a Feistel structure layer and the other is an SPN structure layer. Each operation used in two layers is S-box or logical operation, which has been well studied about security. It is a strong feature of the cip...
