Generalized Hydrodynamic Description of the Page Curve-like Dynamics of a Freely Expanding Fermionic Gas.

We consider an analytically tractable model that exhibits the main features of the Page curve characterizing the evolution of entanglement entropy during evaporation of a black hole. Our model is a gas of noninteracting fermions on a lattice that is released from a box into the vacuum. More precisely, our Hamiltonian is a tight-binding model with a defect at the junction between the filled box and the vacuum.

A simple freeze-thaw based method for efficient purification of recombinant human proinsulin from inclusion bodies.

Insulin is a pivotal peptide hormone essential for regulating glucose homeostasis. It has been known for over 100 years, but its production and purification methods are still under improvement. Escherichia coli based bacterial expression system is primarily used for insulin production.

A method for authenticating the fidelity of knockout collections.

Gene knockout strain collections are important tools for discovery in microbiology. The only available genome-wide deletion collection for a human pathogenic fungus, is utilized widely for genetic studies. We uncovered mix-ups in the assembly of the commercially available deletion collection of ∼6,000 unique strains acquired by our lab.
