A frequent and well-founded criticism of the maximum a posteriori (MAP) and minimum mean squared error (MMSE) estimates of a continuous parameter γ taking values in a differentiable manifold Γ is that they are not invariant to arbitrary ‘reparametrizations’ of Γ. This paper clarifies the issues surrounding this problem, by pointing out the difference between coordinate invariance, which is a si...

The aim of the present study was to derive multiple regression equations for in vivo estimation of the carcass lean and fat content in Muscovy ducks. The experimental materials consisted of 240 White Muscovy ducklings (120 male and 120 female). One hundred sixteen females aged 10 wk and 112 males aged 12 wk were slaughtered. Before slaughter the ducks were weighed, and the following body measur...

Abstract The formation of fluvial dunes is usually studied by investigating the time development a small amplitude bottom perturbation uniform stream and considering that originate growth mode characterized largest amplification rate under assumption an infinite availability mobile sediment (linear stability analysis). Here we undertake analysis sand in steady currents accounting for nonlinear ...

During vertebrate development, trunk neural crest cells delaminate along the entire length of the dorsal neural tube and initially migrate as a non-segmented sheet. As they enter the somites, neural crest cells rearrange into spatially restricted segmental streams. Extracellular matrix components are likely to play critical roles in this transition from a sheet-like to a stream-like mode of mig...

Exoskeletons can be utilized for rehabilitation purposes as well as for assistance and augmentation of motion of patients with disabilities, workers, the elderly and even healthy people. Compared to powered solutions, unpowered passive exoskeletons have been shown to have significantly higher chances of end user acceptance, because of simpler design, no complex electronics and potentially lower...

A significant number of bone marrow biopsies are performed annually. Outcomes of patient pain and sample size of biopsy are important issues as perception of patient pain is underestimated by clinicians and sample size assists in accurate diagnosis. Manual extraction of marrow biopsy is the main method used. Recently a powered system has been introduced. The objectives of this systematic review...

To investigate anthropometric characteristics of Chinese professional female marathoners and suitable predicted variables correlated with their personal bests (PB), 96 Chinese female long-distance runners were divided into international (< 2 h 34 min), national (2 h 34 min~2 h 45 min) and average (2 h 45 min~3 h 19 min) levels according to their PB in marathon during the process of talent ident...

introduction: whitening toothpastes which have been accepted in populations may affect properties of enamel and restorative materials. the aim of this study was to compare the microhardness of human enamel and z250 microhybrid composite resin after brushing with two whitening toothpastes. materials and methods: in this experimental study of enamel specimens, forty five freshly extracted human i...

Powered by UV light, nano/micrometer-sized silver chloride particles exhibit autonomous movement and form "schools" in aqueous solution, i.e. regions in which the number density of particles is significantly higher than the global average. In this paper, the silver chloride particles in such a system are classified by their proximity to other AgCl particles--be they isolated, coupled or schoole...

In the multifunctional system consisting of point absorber wave energy converters and a pontoon breakwater, breakwater plays an essential role in attenuating waves on lee side amplifying for better harvesting stoss side. The structure is expectedly improved to enhance its attenuation amplification at same time. Here we present novel parabolic arc show that range typical regular incident waves, ...
