Forms, forces, and stem cell fate [PDF]
Current Opinion in Cell Biology, 2014 Cells change their shape and mechanics dramatically during development and tissue healing in response to morphogens, cell-cell contact, adhesion to extracellular matrix, and more. Several regulatory links have been described between cell shape, cytoskeletal tension, matrix adhesiveness and stiffness, and recent studies have begun to uncover how these ...

Nematic Skyrmions in Odd-Parity Superconductors
, 2017 We study topological excitations in two-component nematic superconductors, with a particular focus on Cu$_x$Bi$_2$Se$_3$ as a candidate material. We find that the lowest-energy topological excitations are coreless vortices: a bound state of two spatially

Elasticity-driven Nanoscale Texturing in Complex Electronic Materials [PDF]
, 2003 Finescale probes of many complex electronic materials have revealed a non-uniform nanoworld of sign-varying textures in strain, charge and magnetization, forming meandering ribbons, stripe segments or droplets. We introduce and simulate a Ginzburg-Landau

Mapping the evolution of mitochondrial complex I through structural variation
FEBS Letters, EarlyView.Respiratory complex I (CI) is crucial for bioenergetic metabolism in many prokaryotes and eukaryotes. It is composed of a conserved set of core subunits and additional accessory subunits that vary depending on the organism. Here, we categorize CI subunits from available structures to map the evolution of CI across eukaryotes. Respiratory complex I (CI)

Glocalisation of global market forces and the repositioning of a peripheral Russian mining community [PDF]
, 2015 Increasing globalisation and global market forces shape the development of resource peripheries in the Barents region. Foreign direct investments are concrete example of global market forces.

Organoids in pediatric cancer research
FEBS Letters, EarlyView.Organoid technology has revolutionized cancer research, yet its application in pediatric oncology remains limited. Recent advances have enabled the development of pediatric tumor organoids, offering new insights into disease biology, treatment response, and interactions with the tumor microenvironment.

Estudios de Teoría Literaria, 2021 Literature, philosophy and art can either be seen as an aesthetical form or as distinct moments of the explosive force of life, a process of constant ‘becoming’. Antonio Candido conceives of literature as a social project but he is equally at home in textual analyses, in a sophisticated and unusual perspective.

Do Lognormal Column-Density Distributions in Molecular Clouds Imply Supersonic Turbulence?
, 2010 Recent observations of column densities in molecular clouds find lognormal distributions with power-law high-density tails. These results are often interpreted as indications that supersonic turbulence dominates the dynamics of the observed clouds.

Generic Mechanism of Emergence of Amyloid Protofilaments from Disordered Oligomeric aggregates [PDF]
, 2008 The presence of oligomeric aggregates, which is often observed during the process of amyloid formation, has recently attracted much attention since it has been associated with neurodegenerative conditions such as Alzheimer's and Parkinson's diseases.
