Security of multiparty quantum secret sharing with multiqubit ghz states

Abstract: We study the security of multiparty quantum secret sharing (QSS) with multiqubit Greenberger–Horne–Zeilinger states. We give a detailed proof that the original scheme of Xiao et al. [Phys. Rev. A69 (2004) 052307] is insecure against the interior attack (i.e. the participants' attack) which is the most serious threat for QSS protocols. Thereafter, an improvement of this QSS protocol is proposed.

Supervision and Management for the Supervisors

Abstract: Under the situation that the central authorities of state decide to change the leading system of discipline inspection committee—from" double vertical leading mechanism"to"unified management" A new problem occurs that needs urgent consideration and solution as to how to strengthen the supervision and management of the supervisors, preventing the supervisors from ignoring inspection and abusing their authorities as wellOnly by catching thinking education and system restraint and building the perfect and standard system of management and supervision, can we really develop the efficacy and functions of the supervising department

On certain quasiconformal and elliptic mappings.

Abstract: Let $\overline{\mathbb{D}}$ be the closure of the unit disk $\mathbb{D}$ in the complex plane $\mathbb{C}$ and $g$ be a continuous function in $\overline{\mathbb{D}}$. In this paper, we discuss some characterizations of elliptic mappings $f$ satisfying the Poisson's equation $\Delta f=g$ in $\mathbb{D}$, and then establish some sharp distortion theorems on elliptic mappings with the finite perimeter and the finite radial length, respectively. The obtained results are the extension of the corresponding classical results.

Urban Ecosystem Health Evaluation and Analysis Based on DPSIR Model ——A Case Study in Hengyang

Abstract: Based on DPSIR model,A evaluation index of city eco-system health was established,which inclued driving force,pressure,state,and related response five aspects.The weights of the indice are given by analytic hierarchy process and the evaluation model was build using the fuzzy mathematics method.The value of ecosystem health index was caculated during 2004—2008 in hengyang.The results showed that the overall health of Hengyang City was pathological in 2004,unhealthy during 2005—2007 and sub-health state in 2008.
