Recent results showing PPAD-completeness of the problem of computing an equilibrium for Fisher’s market model under additively separable, piecewise-linear, concave utilities (plc utilities) have dealt a serious blow to the program of obtaining efficient algorithms for computing equilibria in “traditional” market models and has prompted a search for alternative models that are realistic as well ...

The transient behavior of muscle in double-or multiple-step length perturbations [Lombardi, V., Piazzesi, G. & Linari, M. (1992) Nature (London) 355, 638-641] is simulated with a "conventional" cross-bridge model, which has been reported [Eisenberg, E., Hill, T. L. & Chen, Y. (1980) Biophys. J. 29, 195-227] to account for many mechanical, as well as biochemical, muscle data. The quick recovery ...

CO2 capture attracts significant research efforts in order to reduce the volume of greenhouse gases emitted from fossil fuels combustion. Among studied processes, chemical absorption represents a mature approach and, this direction, new solvents, alternatives monoethanolamine (MEA), have been suggested. In work, solubility aqueous solutions 2-amino-2-methyl-1-propanol (AMP) and 3-(methylamino)p...

In the early 1980s research began to reveal high rates of sexual offending in various English-speaking countries (Baker & Duncan, 1985; Finkelhor, 1984; Russell, 1984). Unfortunately, the response by both the media and politicians to these revelations took the form of harsh punishments for the offenders (FreemanLongo & Blanchard, 1998; Sampson, 1994). This approach was consistent with the senti...
