We show that the stochastic background of gravitational waves, produced in the early cosmological epochs, strictly depends on the assumed theory of gravity. In particular, the specific form of the function f(R), where R is the Ricci scalar, is related to the evolution and the production mechanism of gravitational waves. Using a neural network algorithm which only requires non-Gaussian nature an...

Abstract In order to investigate the charge symmetry breaking (CSB) in the short range part of the nuclear force, we calculate the difference of the masses of the neutron and the proton, ∆M, the difference of the scattering lengths of the p-p and n-n scatterings, ∆a, and the difference of the analyzing power of the proton and the neutron in the n-p scattering, ∆A(θ), by a quark model. In the pr...

dS/CFT gives a perturbatively gauge invariant definition of particle masses in de Sitter (dS) space. We show, in a toy model in which the graviton is replaced with a minimally coupled massless scalar field, that loop corrections to these masses are infrared (IR) divergent. We argue that this implies anomalous dependence of masses on the cosmological constant, in a true theory of quantum gravity...

The recent publication by the U.S. Chemical Safety Board (CSB) concerning its findings on the Concept Sciences Inc. (CSI) incident involving hydroxylamine (HA) has raised issues with regard to safe production of HA. This CSI incident was followed by another incident that destroyed the Nissin Chemical HA plant in Japan, and today BASF is the sole commercial producer of HA. HA is an important sol...

Employees’ non-malicious counterproductive computer security behaviors (CCSB) at work could put organizations’ information-related assets at risk, if unchecked. Using concepts from the social cognitive and organizational citizenship behavior (OCB) theoretical frameworks, this study examined the effects of observational learning/modeling, social support, and OCB (i.e., helping behaviors and civi...

librarians are frequently consulted about proper citation formats and support the use of pc-based personal bibliographic citation management programs, such as endnote, often used by faculty and graduate students. recently, free or inexpensive web-based tools have been developed that create citations and format bibliographies. an analysis of citations generated by these programs shows that they ...

rosa damascena mill l., known as gole mohammadi in iran is one of the most important species of rosaceae family flowers. r. damascena is an ornamental plant and beside perfuming effect, several pharmacological properties including anti-hiv, antibacterial, antioxidant, antitussive, hypnotic, antidiabetic, and relaxant effect on tracheal chains have been reported for this plant. this article is a...
