Dissecting myosin-5B mechanosensitivity and calcium regulation at the single molecule level
Nature Communications, 2018 Myosin-5B is an actin-based motor important for endosome recycling, but the molecular mechanism underlying its motility remains unknown. Here authors use single molecule imaging and high-speed laser tweezers to dissect the mechanoenzymatic properties of ...

Actively tunable plasmonic lens for subwavelength imaging at different wavelengths [PDF]
arXiv, 2011 A type of tunable plasmonic lens with nanoslits is proposed for subwavelength imaging in the far field at different wavelengths. The nanoslits array in the plasmonic lens, which have constant depths but varying widths, could generate desired optical phase retardations based on the particular propagation property of the Surface Plasmon Polaritons (SPPs)

A Spectroscopic Survey of the Fields of 28 Strong Gravitational Lenses: Implications for $H_0$
, 2017 Strong gravitational lensing provides an independent measurement of the Hubble parameter ($H_0$). One remaining systematic is a bias from the additional mass due to a galaxy group at the lens redshift or along the sightline.

A new construction of lens spaces [PDF]
arXiv, 2013 Let $T^n$ be the real $n$-torus group. We give a new definition of lens spaces and study the diffeomorphic classification of lens spaces. We show that any $3$-dimensional lens space $L(p; q)$ is $T^2$-equivariantly cobordant to zero. We also give some sufficient conditions for higher dimensional lens spaces $L(p; q_1, \ldots, q_n)$ to be $T^{n+1 ...

Advanced Functional Materials, EarlyView.Surface‐attached multilayer micromagnet systems are fabricated by two‐photon crosslinking. The pillar‐shaped micro actuators consist of a soft and flexible surface‐attached cell‐repellent hydrogel layer at the bottom, acting as a hinge and a cell‐adhesive hydrophobic polymer filled with magnetic nanoparticles.
