Bigelow Aerospace has stated that BEAM can resist high velocity impacts from small particles just as well as rigid alternatives.
Expandable modules are especially attractive for these inherently costly missions because they're relatively lightweight and compact compared to rigid alternatives, making them potentially cheaper and easier to launch.
Two design examples are proposed to demonstrate the application of the proposed semi-rigid design methods, and their results compared to pinned and rigid alternatives.
By mimicking the natural tissue environment, elastic materials are able to integrate within the body to promote repair and avoid the adverse physiological responses seen in rigid alternatives that often disrupt tissue function.
However, when all phases are taken into consideration, the rigid pavement alternatives have lower environmental impacts and costs.
Moreover, these "inconvenient truths" not only exist in other universes, but may also exist in ours as well: "Initial findings from our research group indicate that within our own universe, in addition to matter and dark matter, there may also be 'alternative matter', which operates according to rigid rules of alternative facts and alternative laws.
"The existing three-part system is far too rigid to allow alternative pathways into the profession," says the group chair Alex Wright, who is optimistic that "there's a growing realisation that maintaining the status quo is no longer an option".
One other possible improvement is to incorporate MHC flexibility by sampling peptide-contacting MHC residue rotamer conformations or utilizing multiple alternative rigid models of the binding cleft in the docking procedure.
Our beliefs can elevate and inspire, and well-policed secularism – a version of secularism that doesn't itself become an alternative set of rigid, aggressive beliefs – could help us to do both.
Dynamic stabilization devices have been introduced to clinics as an alternative to rigid fixation.
