Like all human individual differences, personality traits and intelligence are substantially heritable. From an evolutionary perspective, this poses the question what evolutionary forces maintain their genetic variation. Information about the genetic architecture and associations with evolutionary fitness permit inferences about these evolutionary forces. As our understanding of the genomics of...
A parylene coating is frequently used to prevent corrosion of neodymium-iron-boron magnets when they are used intra-orally. This in vitro study was designed to test the durability of parylene coating in a simulated oral environment. Single and double parylene-coated magnets were subjected to grinding and crushing forces in an industrial ball mill. The results demonstrate that abrasion and wear ...
In the (t, n) threshold signature schemes with the assistance of a trusted party, the trusted party easily becomes the targets of attack. And an authority which can be trusted by all players doesn't exist. So the schemes without a trusted party were proposed to solve those security problems. But all of the conventional schemes without a trusted party cannot withstand conspiracy attacks. A novel...
Dynamic system fault diagnosis is often faced with a large number of possible faults. The purpose this paper to propose an efficient method for such situations. To avoid intractable combinatorial problems, sparse estimation techniques appear be powerful tool isolating faults, under the assumption that only small faults can simultaneously active. However, studied in framework <italic xmlns:mml="...
Existence of cracks in industrial structures is one of the important causes of their failure, especially when they are subjected to important axial compressive forces that might lead to buckling. Therefore, it must be considered in stress analysis and designing and loading of such structures. In this paper, the buckling and post-buckling behaviors of stainless-steel cracked plates under axial c...
the space now known as complete erdos space ec was introduced by paul erdos in 1940 as the closed subspace of the hilbert space ?2 consisting of all vectors such that every coordinate is in the convergent sequence {0} ? { 1 n : n ? n}. in a solution to a problem posed by lex g. oversteegen we present simple and useful topological characterizations of ec. as an application we determine the ...

Introduction: Manual load lifting is the most common and most stressful activity in manual handling of loads that imposes the highest possible amount of biomechanical pressure on the body, particularly on the spine. The present study was conducted to determine the prevalence of musculoskeletal disorders and to estimate the mechanical force exerted on the lower back in workers responsible f...
The objective of this seminar will be to review some physical methods of stimulation of bone healing. Most cells in the body experience a range of physical forces, which when isolated individually are capable of modulating cellular activity. Gravitational, acoustic, thermal, shear, compressive/tensile, electrical and hydrostatic forces can all result in a cellular response. We will cover 3 moda...
