Michael Dahms,Wolfgang Weißbachre descriptive, in the sense that it conveys the notion that the domain is surrounded by a solid boundary. A tube terminated at both ends is the simplest configuration to analyze. Sections . and . addressed planar waves in such a system, but our concern here will extend to higher order waveguide mod

Michael Dahms,Wolfgang Weißbachthe case in acoustics, as exemplified by an explosion, wherein peak pressures might be well above atmospheric. However, even if the pressure is not large, there is another parameter whose largeness might require consideration of nonlinear effects.

E. Candolfi,O. Villard,M. Thouvenin,T. T. Kieno produce new descendant cells or when a disease or tissue damage activates their proliferation with the aim of repairing the tissue. In response to damage, stem cells secrete components of the extracellular matrix components, paracrine factors, and extracellular vesicles, primarily exosomes, and ca
