Mechanical Checkpoint Regulates Monocyte Differentiation in Fibrotic Niches
(Springer Science and Business Media LLC, 2022-07-11) -
Mechanical control of tissue and organ development
(Company of Biologists, 2010)Many genes and molecules that drive tissue patterning during organogenesis and tissue regeneration have been discovered. Yet, we still lack a full understanding of how these chemical cues induce the formation of living ... -
Mechanical control of tissue morphogenesis during embryological development
(University of the Basque Country Press, 2006)Twenty years ago, we proposed a model of developmental control based on tensegrity architecture, in which tissue pattern formation in the embryo is controlled through mechanical interactions between cells and extracellular ... -
Mechanical Design and Locomotion of Modular-Expanding Robots
(Institute of Electrical and Electronics Engineers (IEEE), 2010) -
Mechanical Model of Globular Transition in Polymers
(Wiley-Blackwell, 2014)In complex, multicomponent systems, polymers often undergo phase transitions between distinct conformations. This paper reports a millimeter-scale granular model of coil-to-globule transitions: one “polymer” chain—a ... -
Mechanical Properties of Warped Membranes
(American Physical Society, 2013)We explore how a frozen background metric affects the mechanical properties of planar membranes with a shear modulus. We focus on a special class of “warped membranes” with a preferred random height profile characterized ... -
Mechanical Reinforcement of Polymeric Fibers through Peptide Nanotube Incorporation
(American Chemical Society (ACS), 2013)High aspect ratio nanotubular assemblies can be effective fillers in mechanically reinforced composite materials. However, most existing nanotubes used for structural purposes are limited in their range of mechanical, ... -
The mechanical scaling of coasting in zebrafish (Danio rerio)
(The Company of Biologists, 2005)Many fish species span two or three orders of magnitude in length during the growth from larvae to adults, and this change may have dramatic consequences for locomotor performance. We measured how the performance of coasting ... -
Mechanical slowing-down of cytoplasmic diffusion allows in vivo counting of proteins in individual cells
(Nature Publishing Group, 2016)Many key regulatory proteins in bacteria are present in too low numbers to be detected with conventional methods, which poses a particular challenge for single-cell analyses because such proteins can contribute greatly to ... -
Mechanically robust lattices inspired by deep-sea glass sponges
(Springer Science and Business Media LLC, 2020-09-21)The predominantly deep-sea hexactinellid sponges are known for their ability to construct remarkably complex skeletons from amorphous hydrated silica. The skeletal system from one such example, Euplectella aspergillum, ... -
Mechanically tunable phononic band gaps in three-dimensional periodic elastomeric structures
(Elsevier BV, 2012)Three-dimensional periodic structures have many applications in acoustics and their properties are strongly related to structural details. Here we demonstrate through simulations the ability to tune the phononic band gaps ... -
Mechanically Versatile Soft Machines through Laminar Jamming
(Wiley, 2018-02-26)There are two major structural paradigms in robotics: soft machines, which are conformable, durable, and safe; and traditional rigid robots, which are fast, precise, and capable of applying high forces. Here, the paradigms ... -
Mechanics and dynamics of translocating MreB filaments on curved membranes
(eLife Sciences Publications, Ltd, 2019-02-18)MreB is an actin homolog that is essential for coordinating the cell wall synthesis required for the rod shape of many bacteria. Previously we have shown that filaments of MreB bind to the curved membranes of bacteria and ... -
Mechanics of a process to assemble microspheres on a patterned electrode
(AIP Publishing, 2006) -
Mechanics of evolutionary digit reduction in fossil horses (Equidae)
(The Royal Society, 2017)Digit reduction is a major trend that characterizes horse evolution, but its causes and consequences have rarely been quantitatively tested. Using beam analysis on fossilized centre metapodials, we tested how locomotor ... -
Mechanics of Individual, Isolated Vortices in a Cuprate Superconductor
(Nature Publishing Group, 2009)Superconductors often contain quantized microscopic whirlpools of electrons, called vortices, that can be modelled as one-dimensional elastic objects1. Vortices are a diverse area of study for condensed matter because of ... -
Mechanics of Supercooled Liquids
(ASME International, 2014)Pure substances can often be cooled below their melting points and still remain in the liquid state. For some supercooled liquids, a further cooling slows down viscous flow greatly, but does not slow down self-diffusion ... -
The mechanics of tip growth morphogenesis: what we have learned from rubber balloons
(Mathematical Sciences Publishers, 2007)Morphogenesis of plant, fungal, and bacterial cells depends heavily on surface mechanics and in particular on the stiff wall that surrounds these cells. In this paper, we show that tubular rubber balloons offer a useful ... -
Mechanism Design: How to Implement Social Goals
(American Economic Association, 2008)The theory of mechanism design can be thought of as the “engineering” side of economic theory. Much theoretical work, of course, focuses on existing economic institutions. The theorist wants to explain or forecast the ... -
Mechanism for clogging of microchannels
(American Physical Society, 2006)We investigate clogging of microchannels at the single-pore level using microfluidic devices as model porous media. The process of clogging is studied at low volume fractions and high flow rates, a technologically important ...
