Universality class of the reversible-irreversible transition in sheared suspensions

GI Menon, S Ramaswamy - Physical Review E, 2009 - APS
Collections of non-Brownian particles suspended in a viscous fluid and subjected to oscillatory
shear at very low Reynolds number have recently been shown to exhibit a remarkable …

Direct observation of the flux-line vortex glass phase in a type II superconductor

…, FY Ogrin, D Charalambous, EM Forgan, GI Menon… - Physical review …, 2004 - APS
The order of the vortex state in La 1.9 Sr 0.1 CuO 4 is probed using muon-spin rotation and
small-angle neutron scattering. A transition from a Bragg glass to a vortex glass is observed, …

[HTML][HTML] Comparing COVID-19 vaccine allocation strategies in India: A mathematical modelling study

BH Foy, B Wahl, K Mehta, A Shet, GI Menon… - International Journal of …, 2021 - Elsevier
Background The development and widespread use of an effective SARS-CoV-2 vaccine
could prevent substantial morbidity and mortality associated with COVID-19 and mitigate the …

Numerical method of lines for the relaxational dynamics of nematic liquid crystals

AK Bhattacharjee, GI Menon, R Adhikari - Physical Review E, 2008 - APS
We propose an efficient numerical scheme, based on the method of lines, for solving the
Landau–de Gennes equations describing the relaxational dynamics of nematic liquid crystals. …

Chromatin compaction, auxeticity, and the epigenetic landscape of stem cells

K Tripathi, GI Menon - Physical Review X, 2019 - APS
When embryonic stem cells differentiate, the mechanical properties of their nuclei evolve en
route to their terminal state. Measurements of the deformability of cell nuclei in the …

Muons as local probes of three-body correlations in the mixed state of type-II superconductors

GI Menon, A Drew, UK Divakar, SL Lee, R Gilardi… - Physical review …, 2006 - APS
The vortex glass state formed by magnetic flux lines in a type-II superconductor is shown to
possess nontrivial three-body correlations. While such correlations are usually difficult to …

Chromosome positioning from activity-based segregation

N Ganai, S Sengupta, GI Menon - Nucleic acids research, 2014 - academic.oup.com
Chromosomes within eukaryotic cell nuclei at interphase are not positioned at random, since
gene-rich chromosomes are predominantly found towards the interior of the cell nucleus …

[HTML][HTML] Biophysics of cell-substrate interactions under shear

…, P Kondaiah, P Pullarkat, GI Menon… - Frontiers in cell and …, 2019 - frontiersin.org
Cells adhere to substrates through mechanosensitive focal adhesion complexes. Measurements
that probe how cells detach from substrates when they experience an applied force …

[PDF][PDF] Correlated spatio-temporal fluctuations in chromatin compaction states characterize stem cells

S Talwar, A Kumar, M Rao, GI Menon… - Biophysical journal, 2013 - cell.com
Stem cells integrate signals from the microenvironment to generate lineage-specific gene
expression programs upon differentiation. Undifferentiated cell nuclei are easily deformable, …

Self-organized pattern formation in motor-microtubule mixtures

S Sankararaman, GI Menon, PBS Kumar - Physical Review E, 2004 - APS
We model the stable self-organized patterns obtained in the nonequilibrium steady states of
mixtures of molecular motors and microtubules. In experiments [Nédélec et al., Nature (…
