Psychophysics of time perception and valuation in temporal discounting of gain and loss

Han, Ruokang; Takahashi, Taiki - In: Physica A: Statistical Mechanics and its Applications 391 (2012) 24, pp. 6568-6576

Anomalies in intertemporal choice (e.g. “hyperbolic” discounting and sign effect) have been investigated in econophysics and behavioral neuroeconomics. We experimentally examined the roles of psychophysical effects of time perception and subjective valuation of outcomes (value function) on...

Life-space foam: A medium for motivational and cognitive dynamics

Ivancevic, Vladimir; Aidman, Eugene - In: Physica A: Statistical Mechanics and its Applications 382 (2007) 2, pp. 616-630

General stochastic dynamics, developed in a framework of Feynman path integrals, have been applied to Lewinian field-theoretic psychodynamics [K. Lewin, Field Theory in Social Science, University of Chicago Press, Chicago, 1951; K. Lewin, Resolving Social Conflicts, and, Field Theory in Social...

Personal recommendation via modified collaborative filtering

Liu, Run-Ran; Jia, Chun-Xiao; Zhou, Tao; Sun, Duo; … - In: Physica A: Statistical Mechanics and its Applications 388 (2009) 4, pp. 462-468

In this paper, we propose a novel method to compute the similarity between congeneric nodes in bipartite networks …. Different from the standard cosine similarity, we take into account the influence of a node’s degree. Substituting this new … definition of similarity for the standard cosine similarity, we propose a modified collaborative filtering (MCF). Based on a …

Biologically-inspired stochastic vector matching for noise-robust information processing

Ueda, Michihito; Ueda, Masahiro; Takagi, Hiroaki; Sato, … - In: Physica A: Statistical Mechanics and its Applications 387 (2008) 16, pp. 4475-4481

“End of Moore’s Law” has recently become a topic. Keeping the signal-to-noise ratio (SNR) at the same level in the future will surely increase the energy density of smaller-sized transistors. Lowering the operating voltage will prevent this, but the SNR would inevitably degrade. Meanwhile,...

3-D maps and coupling numbers for protein sequences

Li, Chun; Yu, Xiaoqing; Yang, Liu; Zheng, Xiaoqi; Wang, … - In: Physica A: Statistical Mechanics and its Applications 388 (2009) 9, pp. 1967-1972

Based on a five-letter model of the 20 amino acids, we propose a new 3-D graphical representation of protein sequence. Then we derive from the graphical representation, numerical indices called 3-D coupling numbers, to characterize protein sequences. The examination of the...

How different is a hard-sphere fluid from a suspension of hard-sphere colloids near the glass transition?

Tokuyama, Michio; Terada, Yayoi - In: Physica A: Statistical Mechanics and its Applications 375 (2007) 1, pp. 18-36

This paper compares simulation and experiment to verify how a hard-sphere fluid is different from a suspension of hard-sphere colloids near the glass transition at 6% polydispersity. This is done by performing extensive molecular-dynamic simulations and by analyzing the resultant mean-square...
