Previous work comparing fMRI data for two participants participating in a trust game provides a unique source for the development of an ACT-R model of trust. The model replicates a large portion of the behavior data. Continuing efforts expect to match more of the behavioral data and the imaging data comparison is expected to identify architectural needs.

Quintessence is often invoked to explain the universe's acceleration suggested by type Ia supernovae observations. The aim of this letter is to study the validity of using a constant equation of state for quintessence models. We shall show that this hypothesis strongly constraint the form of the scalar potential. .

Let R be a ring. A construction method for flexible quadratic algebras with scalar involution over R is presented which unifies various classical constructions in the literature, in particular those to construct composition algebras.

We will give an elementary proof of a result of R. Hamilton for Ricci flow on compact surfaces. Let M be a compact surface. We will prove the global existence of solution of the Ricci flow ∂gij/∂t = (r − R)gij on M where R is the scalar curvature and r = R

We show here that the spectrum of the family of noncommutative harmonic oscillators Qw(α,β)(x,D) for α, β ∈ R+ in the range αβ = 1, is [0,+∞) and is entirely essential spectrum. The previous existing results concern the case αβ > 1 (case in which Qw(α,β)(x,D) is globally elliptic with a discrete spectrum whose qualitative properties are being extensively studied), and ours therefore extends the...

Sufficient conditions are given for the existence of oscillatory proper solutions of a differential equation with quasiderivatives Lny = f(t, L0y, . . . , Ln−1y) under the validity of the sign condition f(t, x1, . . . , xn)x1 ≤ 0, f(t, 0, x2, . . . , xn) = 0 on R+ × Rn.

This paper analyzes the likely impacts of the major policy reforms unveiled by the Government of India for revamping the country’s power sector. The provisions of the new enactment have recently come into force and seek a paradigm policy shift in the form of the Electricity Act 2003. The paper details out the key features of the Act and the likely power industry changes being brought about in t...
