Finite Element Simulation of the MRTA Test of a Human Tibia
The mechanical response tissue analyzer (MRTA) tests long bone quality through low frequency, low amplitude vibration in vivo. The MRTA measures complex stiffness over a range of low frequencies, offering a wealth of information on bone composition. Previous MRTA interpretation used lumped …

Reliability and Validity of Mechanical Response Tissue Analysis in Composite and Human Tibiae
… of mechanical response tissue analysis (MRTA). Twenty composite tibiae underwent MRTA testing on three separate days to determine intra- and inter-day reliability of bending stiffness. The bones were then subjected to three-point bending tests to directly determine elastic modulus. …

Self-regulated Multi-robot Task Allocation
… a suitable multi-robot task-allocation (MRTA) solution is required. This must be scalable to variable number of robots and tasks. Recent studies show that biology-inspired self-organized approaches can effectively handle task-allocation in large multi-robot systems. However most existing …

Mechanical Response Tissue Analysis: Inter- and Intra-trial Reliability in Assessing Bending Stiffness of the Human Tibia in College Aged Women
Mechanical Response Tissue Analysis (MRTA) is an emerging technology for assessing maximal bending stiffness (EI) of human long bones in vivo. The MRTA variable, EI, is the product of Young's modulus of elasticity (E) and cross-sectional moment of inertia (I). EI quantifies material and …

Reliability of Tibial Measurement with Mechanical Response Tissue Analysis
Mechanical response tissue analysis (MRTA) provides a noninvasive means of estimating the cross-sectional bending stiffness (EI) of long bones, and thus can serve as a predictor of bone strength. Estimates of bone bending stiffness are derived from the point impedance response of a long bone to low …

Earth pressure balance (EPB) shield tunneling in Bangkok : ground response and prediction of surface settlements using artificial neural networks
… makes use of the fact that in the Bangkok MRTA project, data on ground deformation and shield operation were collected. The tunnel sizes are practically identical and the subsurface conditions over long distances are comparable, which allow one to establish relationships between ground …

Denitrification, Dissimilatory Nitrate Reduction, and Methanogenesis in the Gut of Earthworms (Oligochaeta): Assessment of Greenhouse Gases and Genetic Markers
… a N2O reductase; targets denitrifiers), and mcrA/mrtA (encoding for the methyl-CoM reductase and its isoenzyme; target methanogenic Archaea) were analyzed. For nirK and nirS, cutoff values were calculated to define species-level affiliations according to their sequence similarities. Perionyx …

Influence of Oral Contraceptives on Bone Adaptations to Isokinetic Strength Training in Young Women
… using isokinetic dynamometers. BMD and EIMRTA were assessed using dual-energy x-ray absorptiometry (DXA) and mechanical response tissue analysis (MRTA), respectively. RESULTS: Total leg and arm muscular strength of the trained limb increased by 16% and 15%, respectively (p < 0.001), beyond …
