Using Magnetic Twisting Cytometry to Study Monocyte Activation [PDF]
Biophysical Journal, 2011 Circulating monocytes are key blood cells in a variety of disorders of the immune system. They are critically involved in the development of atherosclerotic lesions due to their ability to leave the blood stream and differentiate into macrophages upon entering sub-endothelial space.

, 2013 In this paper we introduce the concept of metasurfaces which are fully transparent when looking from one of the two sides of the sheet and have controllable functionalities for waves hitting the opposite side (one-way transparent sheets).

Three-dimensional active defect loops [PDF]
, 2020 We describe the flows and morphological dynamics of topological defect lines and loops in three-dimensional active nematics and show, using theory and numerical modeling, that they are governed by the local profile of the orientational order surrounding ...

Optical Activity in Twisted Solid-Core Photonic Crystal Fibers [PDF]
Physical Review Letters, 2013 In this Letter we show that, in spectral regions where there are no orbital cladding resonances to cause transmission loss, the core mode of a continuously twisted photonic crystal fiber (PCF) exhibits optical activity, and that the magnitude of the associated circular birefringence increases linearly with twist rate and is highly reproducible.

Chromatin remodelers couple inchworm motion with twist-defect formation to slide nucleosomal DNA. [PDF]
PLoS Computational Biology, 2018 ATP-dependent chromatin remodelers are molecular machines that control genome organization by repositioning, ejecting, or editing nucleosomes, activities that confer them essential regulatory roles on gene expression and DNA replication.

Evidence of Twisted Flux-Tube Emergence in Active Regions [PDF]
Solar Physics, 2014 Elongated magnetic polarities are observed during the emergence phase of bipolar active regions (ARs). These extended features, called magnetic tongues, are interpreted as a consequence of the azimuthal component of the magnetic flux in the toroidal flux-tubes that form ARs. We develop a new systematic and user-independent method to identify AR tongues.

Forward and inverse problems in the mechanics of soft filaments [PDF]
Royal Society Open Science, 2018 Soft slender structures are ubiquitous in natural and artificial systems, in active and passive settings and across scales, from polymers and flagella, to snakes and space tethers. In this paper, we demonstrate the use of a simple and practical numerical

Evolution of twist-shear and dip-shear in Faring active region NOAA 10930
, 2010 We study the evolution of magnetic shear angle in a flare productive active region NOAA 10930. The magnetic shear angle is defined as the deviation in the orientation of the observed magnetic field vector with respect to the potential field vector.
