We prove that for d > 1 the information rate of the perfect secret sharing scheme based on the edge set of the d-dimensional cube is exactly 2/d. Using the technique developed, we also prove that the information rate of the infinite d-dimensional lattice is 1/d.

In combinatorial group testing problems Questioner needs to find a defective element x ∈ [n] by testing subsets of [n]. In [18] the authors introduced a new model, where each element knows the answer for those queries that contain it and each element should be able to identify the defective one. In this article we continue to investigate this kind of models with more defective elements. We also...

in addition to ultrasonographic monitoring of folliculogenesis, urinary luteinizing hormone testing, luteal phase endometrial biopsy, serum antiphospholipid antibodies, etc., immunologic tests are recently being used to evaluate reproductive disorders. in this study, sharing of hla-a, b, c and dr antigens and the presence of antipaternal cytotoxic antibody (apca) was assessed using microcytotox...

Nowadays, knowledge sharing as one of the components of knowledge management process, has a significant role in organization success. Knowledge causes organizations to be able to acquire knowledge faster and more effective than before, and also apply it which therefore cause them to create competitive advantage. This research is an attempt to investigate the effects of knowledge sharing on inno...

Knowledge sharing is a complex behavior. To show this complexity and ways of improving it, the intermediary role of attitudes, cognitive norms, and motivation seem to be important when considering the interaction between this complex behavior and personality traits. To show this relationship, a sample of 357 teachers from among all 570 high school teachers in Birjand was selected and then giv...
