I’m sorry to report that we’re all about to become obsolete. For proof, one need look no farther than the story that swept the globe 2 September. Here’s how the Toronto Star informed its readers: “Scientists have genetically engineered smarter mice, pointing the way to a brave new world in which parents could — in theory, at least — create baby Einsteins.” The news graced the front page of pape...

This study examines the influence of psychological contracts on the relations between social ties and knowledge exchange in virtual teams. We empirically tested our model in a field study of virtual teams in a large, multinational R&D firm. Results of structural equation modeling suggest two important antecedents to psychological contracts of knowledge sharing: instrumental and relational embed...

Abstract There is great interest in the construction of brane worlds, where matter and gravity are forced to be effective only a lower dimensional surface, . How these could appear as consequence string theory crucial question this has been widely discussed. Here we will examine distinct scenario that appears dynamical tension theories positive between two surfaces separated by short distance a...

The accelerated expansion of the universe has been established through observations supernovae, growth structure, and cosmic microwave background. most popular explanation is Einsteins cosmological constant, or dynamic variations hereof. A recent paper demonstrated that if dark matter particles are endowed with a repulsive force proportional to internal velocity dispersion galaxies, then corres...

Using the mathematical aspects of Schwarzschild metric, we present different variables transformation which proves that central singularity hypothesis does not exist. The geometric interpretation black hole from metric is mathematically convincing. approaches taken by many authors were viewed, such as Painleve and its complex variant, to deduce a with throat sphere leads mirror space-time. Subs...

this paper aims to study a generalized double sinh-gordon equation, which appears in several physical phenomena such as integrable quantum field theory, kink dynamics and fluid dynamics. lie symmetry analysis together with the simplest equation method is used to obtain exact solutions for this equation. moreover, we derive conservation laws for the equation by using two different approaches, na...
