Probing the ionotropic activity of glutamate GluD2 receptor in HEK cells with genetically-engineered photopharmacology

open access: yeseLife, 2020
Glutamate delta (GluD) receptors belong to the ionotropic glutamate receptor family, yet they don’t bind glutamate and are considered orphan. Progress in defining the ion channel function of GluDs in neurons has been hindered by a lack of pharmacological

Wordle is NP-hard

open access: yesCoRR, 2022
Wordle is a single-player word-guessing game where the goal is to discover a secret word $w$ that has been chosen from a dictionary $D$. In order to discover $w$, the player can make at most $\ell$ guesses, which must also be words from $D$, all words in $D$ having the same length $k$.

Contractibility and NP‐completeness [PDF]

open access: yesJournal of Graph Theory, 1987
AbstractFor a fixed graph H, let H‐CON denote the problem of determining whether a given graph is contractible to H. The complexity of H‐CON is studied for H belonging to certain classes of graphs, together covering all connected graphs of order at most 4.
