Propolis, a natural product derived from plant resins collected by honeybees, has been reported to exert a wide spectrum of biological functions. This research aimed at investigating the effect of propolis on the proliferation of human leukaemia HL-60 cells and whether propolis might induce apoptosis in HL-60 cells. The results showed dose- and(More)
Cadmium, a well-known toxic heavy metal, affects cellular physiology by disturbing cellular signaling pathways. We investigate the effect of cadmium on cellular differentiation using 3T3-L1 preadipocyte cell lines as an in vitro model. Here, it was shown that cadmium (3 μM) significantly decreased both glycerol-3-phosphate dehydrogenase (GPDH) activity and(More)
In this paper, we investigate the impact of a single edge on the capacity region of a network of error-free, point-to-point links. A family of networks and edges is said to exhibit the “edge removal property” if for any network and edge in the family, removing a δ-capacity edge changes the capacity region by at most δ in each(More)
This paper studies independent cascade models where influence propagates from seed-nodes along edges with independent probabilities. Upper-bounds for the expected number of influenced nodes were previously proposed using the spectral norm of a Hazard matrix. However, these bounds turn out loose in many cases, in particular with respect to sensitive edges(More)
In secure multi-party computations (SMC), parties wish to compute a function on their private data without revealing more information about their data than what the function reveals. In this paper, we investigate two Shannon-type questions on this problem. We first consider the traditional one-shot model for SMC which does not assume a probabilistic prior(More)
This paper develops upper and lower bounds on the influence measure in a network, more precisely, the expected number of nodes that a seed set can influence in the independent cascade model. In particular, our bounds exploit nonbacktracking walks, Fortuin–Kasteleyn–Ginibre (FKG) type inequalities, and are computed by message passing implementation.(More)
