    "abstract": "We point out that theories describing s-wave collisions of bosonic atoms\nconfined in one- or two-dimensional geometries can be extended to much tighter\nconfinements than previously thought. This is achieved by replacing the\nscattering length by an energy-dependent scattering length which was already\nintroduced for the calculation of energy levels under 3D confinement. This\nreplacement accurately predicts the position of confinement-induced resonances\nin strongly confined geometries.",
