Secret sharing scheme realizing general access structure
TL;DR: This paper shows that by providing the trustees with several information data concerning the distributed information of the (k, n) threshold method, any access structure can be realized.
Journal ArticleDOI
Toughness and the existence of k‐factors
TL;DR: For any positive integer k and for any positive real number e, there exists a (k - e)-tough graph G with k|G| even and |G| ⩾ k + 1 which has no k-factor.
Journal ArticleDOI
Multiple assignment scheme for sharing secret
TL;DR: By observing a simple set-theoretic property of an access structure, this paper proposes its mathematical definition and proves that every family satisfying the definition is realized by assigning two more shadows of a threshold scheme to trustees.
Journal ArticleDOI
Contractible edges in 3-connected graphs
TL;DR: It is proved that every 3-connected graph of order at least five has [|G|2] or more contractible edges and the graphs which attain the equality are determined.

TL;DR: In the present study, inhibitory effects on cytokine activity, edema in pulmonary alveoli, and endothelial damage were shown in addition to the favorable effects on catecholamine level, renal function, and peripheral circulation that have already been documented.
