Immobilization in hospitalized medical patients or during simulation of spaceflight induced deconditioning has been shown to be associated with loss of muscle mass and bone. Resistance vibrating exercise (RVE) and/or high protein diet are countermeasures, which are capable of mitigating the adverse effects of immobilization. We investigated the effect of these countermeasures on the coagulation...

Bed rest results in marked vascular adaptations, and resistive vibration exercise (RVE) has been shown to be an effective countermeasure. As vibration exercise has practical and logistical limitations, the use of resistive exercise (RES) alone has the preference under specific circumstances. However, it is unknown if RES is sufficient to prevent vascular adaptations to bed rest. Therefore, the ...

What are the functional neuroimaging measurements required for more fully characterizing the events and locations of neocortical activity? A prime assumption has been that modulation of cortical activity will inevitably be reflected in changes in energy utilization (for the most part) changes of glucose and oxygen consumption. Are such a measures complete and sufficient? More direct measures of...

Molecular dynamics (MD) simulations and micromechanical modeling are used to predict the bulk-level Young’s modulus of polycarbonate and polyimide polymer systems as a function of representative volume element (RVE) size and force field type. The bulk-level moduli are determined using the predicted moduli of individual finite-sized RVEs (microstates) using a simple averaging scheme and an energ...

Studies investigating the correlates of immune protection against Yersinia infection have established that both humoral and cell mediated immune responses are required for the comprehensive protection. In our previous study, we established that the bivalent fusion protein (rVE) comprising immunologically active regions of Y. pestis LcrV (100-270 aa) and YopE (50-213 aa) proteins conferred compl...

Ob’ t’ Iec rve: To evaluate the performance of tools for authoring patient database

A new computational mechanics model is proposed to describe the compression response of two-dimensional cellular materials with consideration of microstructural development. In this modeling, processing conditions to fabricate cellular materials are taken into account as a cell-growth mechanism. Representative volume elements (RVE) are generated by the phase-field model. Numerical simulations o...

in this work we simulated the representative volume element (rve) of carbon nanotube (cnt) which is surrounded by high temperature superconductor (ybco) by using ansys finite element software. first we considered perfect model (for ybco and cnt) and investigated the effect of radius, length, and the number of nanotube in young’s modulus of the ybco by applying force on rve. then, a third region...

Abstract Two methods used to construct a microstructural representative volume element (RVE) were evaluated for their accuracy when in crystal plasticity-based finite (CP-FE) model. The RVE-based CP-FE model has been shown accurately predict the complete tensile stress–strain response of Ti–6Al–4V alloy manufactured by laser powder bed fusion. Each method utilized different image-based techniqu...
