Abstract Background The strong linkage disequilibrium (LD) recently found in genic or exonic regions of the human genome demonstrated that LD can be increased by evolutionary mechanisms that select for functionally important loci.This suggests that LD might be stronger in regions conserved among species than in non-conserved regions, since regions
sara stedy price Because of their wide detection range and rich functions, autonomous underwater vehicles (AUVs) are widely used for observing the marine environment, for exploring natural resources, for security and defense purposes, and in many other fields of interest.Compared with a single AUV, a multi-AUV formation can better perform various t
Finding a given location can be based on a variety of strategies, for example on the estimation of spatial relations between landmarks, called spatial orientation.In galliform birds, spatial orientation has been demonstrated convincingly in very young domestic chicks.We wanted to know whether adult Japanese quails (Coturnix coturnix japonica) witho
Directing and concentrating structures are used mainly on water coursers with unstable channel and major sediment transport or in areas with major bank erosion.The main purpose of these structures is to redirect water flow from the stressed and very often eroded bank to the centre of the channel or other parts of the channel, where the water flow m
This paper concentrates on analyzing the stability problems of aperiodic sampled-data systems with time delay.Based on Lyapunov theory, a new time-square-dependent two-side looped-functional (TTLF) is charger rt procharger proposed, which can take full advantage of the second order terms with respect to time.And by using the intrinsic relationships
