Tracer particles sense local stresses in an evolving multicellular spheroid without affecting the anomalous dynamics of the cancer cells

The paper shows tracer particles accurately report local stresses in a growing multicellular spheroid without altering cancer cell dynamics.

Spatially heterogeneous dynamics of cells in a growing tumor spheroid: Comparison between Theory and Experiments

The paper compares theoretical simulations and experimental data on cell movement in tumor spheroids, revealing distinct subdiffusive and superdiffusive dynamics in core and peripheral cells.

Universal nature of collapsibility in the context of protein folding and evolution

The paper resolves the SAXS-FRET controversy by showing that unfolded protein states are universally compact, with β-sheet-rich proteins being more collapsible, and suggests collapsibility constrains protein evolution.

Charge fluctuation effects on the shape of flexible polyampholytes with applications to Intrinsically disordered proteins

The paper investigates charge fluctuation effects on flexible polyampholytes, showing non-monotonic size dependence and implications for intrinsically disordered proteins.

Optimal Information Transfer In Enzymatic Networks: A Field Theoretic Formulation

The paper develops a field-theoretic approach to calculate signal transmission error in enzymatic networks and validates it against simulations.
