We test a mechanism whereby groups are formed endogenously, through the use of voting. Once formed, groups play a public-goods game, where there are economies of scale: the social value of an incremental contribution to the group account increases with the size of the group. Societies of nine people are initially formed randomly into three groups of three(More)
We test a mechanism whereby groups are formed endogenously, through the use of voting. Once formed, groups play a public-goods game, where there are economies of scale: in two treatments the social value of an incremental contribution to the group account increases with the size of the group, but in the second treatment, the social value is capped once a(More)
Trust is an essential component of good social outcomes and effective economic performance. This is particularly true in environments such as the Prisoner's Dilemma or standard public-goods games, where the equilibrium in a one-shot case involves strictly uncooperative behavior. Evolutionary biologists have developed the notion of indirect reciprocity,(More)
With the rapid development of 3GPP and its related techniques, evaluation of system level performance is in great need. However, LTE system level simulator is secured as commercial secrets in most 3GPP members. In this paper, we introduce our Matlab-based LTE system level simulator according to 3GPP specifications and related proposals. We mainly focus on(More)
Basic peptides such as human immunodeficiency virus type 1 (HIV-1) Tat-(48-60) and Drosophila Antennapedia-(43-58) have been reported to have a membrane permeability and a carrier function for intracellular protein delivery. Based on the fluorescence microscopic observations of the vascular endothelial cells (ECV-304) and the primary cultured neuroglial(More)
DNA synthesis and telomerase activity were assessed in nude mice transplanted with hepatic carcinoma. Hepatic cancer cells (SMMC-7721) were implanted into both flanks of each of 14 BALB/C mice synchronized in 12 h of light alternating with 12 h of darkness (LD12:12) for 4 weeks. At 7 timepoints, tumor samples were collected for measurement of cellular DNA(More)
We test a mechanism whereby groups are formed voluntarily, through the use of voting. These groups play a public-goods game, where efficiency increases with group size (up to a limit, in one treatment). It is feasible to exclude group members, to exit one's group, or to form larger groups through mergers involving the consent of both merging groups. We find(More)
AIM To investigate the effects of resistin-like molecule β (RELMβ) over-expression on the invasion, metastasis and angiogenesis of gastric cancer cells. METHODS Human RELMβ encoding expression vector was constructed and transfected into the RELMβ lowly-expressed gastric cancer cell lines SGC-7901 and MKN-45. Gene expression was measured by Western(More)
