This paper presents a new method for modelling the dynamic behaviour of developable ribbons, two dimensional strips with much smaller width than length. Instead of approximating such surface with a general triangle mesh, we characterize it by a set of creases and bending angles across them. This representation allows the developability to be satisfied everywhere while still leaves enough degree...

We study local symmetry breaking problems in the Congest model, focusing on ruling set problems, which generalize the fundamental Maximal Independent Set (MIS) problem. The time (round) complexity of MIS (and ruling sets) have attracted much attention in the Local model. Indeed, recent results (Barenboim et al., FOCS 2012, Ghaffari SODA 2016) for the MIS problem have tried to break the long-sta...

Next to artificial intelligence and big data, blockchains have emerged as one of the most oft-cited technologies associated with digital economy. Leading technology companies recently contributed making used more widely by developing integrated blockchain offerings. The emergence such services yet strikingly clashes original stated goal remove any form central political authority, behind these ...

The theory of Soft power can be applied to the ruling party of social governance. At present, the Chinese Communist Party is facing political corruption, the public lack of political trust in the officials, social injustice and other social issues. It is necessary to construct the party's soft power and consolidate the party's ruling position.
