Hydrostatic pressure (HP) regulates diverse cell behaviors including differentiation, migration, apoptosis, and proliferation. Abnormal HP is associated with pathologies including glaucoma and hypertensive fibrotic remodeling. In this review, recent advances in quantifying and predicting how cells respond to HP across several tissue systems are presented,...

Ultraslow diffusion is characterized by a logarithmic growth of the mean squared displacement (MSD) as a function of time. It occurs in complex arrangements of molecules, microbes, and many-body systems. This paper reviews mechanical models for ultraslow diffusion in heterogeneous media from both macroscopic and microscopic perspectives. Macroscopic...

Cellulose nanopaper, which consists of a porous network of cellulose nanofibrils (CNFs), exhibits excellent mechanical properties with high strength and toughness. The physical mechanisms, including a realizable reduction of defect size in the nanopaper and facile formation/reformation of hydrogen bonds among CNFs, suggest a bottom-up material design...

In this erratum, the author wishes to make several corrections to Shukla (2001, “Hydrodynamics of Diffusive Processes,” ASME Appl. Mech. Rev., 54(5), pp. 391–404) in order to ensure that the content appropriately cites sources from which passages of text were obtained or paraphrased. The author regrets the earlier oversight.

Similitude theory allows engineers, through a set of tools known as similitude methods, to establish the necessary conditions to design a scaled (up or down) model of a full-scale prototype structure. In recent years, to overcome the obstacles associated with full-scale testing, such as cost and setup, research on similitude methods has grown and their...

This paper presents a thorough review of the initiatives carried out in the last 10 years toward the development of active knee prostheses (AKP) for transfemoral amputees. Three selection criteria were employed to filter the works to be considered in the review: (1) a prototype of the prosthesis is available; (2) the mechanical design, instrumentation,...
