Crowd sensing is a new paradigm which leverages the ubiquity of sensor-equipped mobile devices to collect data. To achieve good quality for crowd sensing, incentive mechanisms are indispensable to attract more participants. Most of existing mechanisms focus on the expected utility prior to sensing, ignoring the risk of low quality solution and privacy leakage. Traditional incentive mechanisms s...

It is well-known that the ability of the Vickrey-Clarke-Groves (VCG) mechanism to implement e¢ cient outcomes for private value choice problems does not extend to interdependent value problems. When an agent’s type a¤ects other agents’utilities, it may not be incentive compatible for him to truthfully reveal his type when faced with CGV payments. We show that when agents are informationally sma...

cordance with the mechanism proposed by Jahn, the temperature coefficient leads to a value for the heat of dissociation of ozone into molecular okygen and atomic oxygen. Calculating by thermodynamic methods the concentration of monatomic oxygen at 1000 and 1 atmosphere pressure in 5% ozone, and by kinetic theory methods the number of collisions between molecular ozone and atomic oxygen, it has ...

In 1999, Clarke et al. ((1999) Proc. Natl. Acad. Sci. USA 96, 7232-7237) reported that the nucleation rate of α-helix of oligopeptide AK16 is as slow as 60 ms. In the present study, we measured the nucleation rate of oligopeptide, C17 (DLTDDIMCVKKILDKVG, corresponding to α-helical region of 84th to 100th amino acids of bovine α-lactalbumin) using the same method as Clarke et al. We found only i...
