European Respiratory Journal, 2011 In chronic obstructive pulmonary disease (COPD) patients, pulmonary rehabilitation is a nonpharmacological intervention aimed at improving physical exercise tolerance, dyspnoea and perceived quality of life. However, identifying predictors of clinical response and which patients achieve benefit remains a difficult question to answer with no conclusive ...

Determinants of zeroth order operators [PDF]
arXiv, 2006 We show that the Szego regularized determinant of a zeroth order operator differs from the zeta regularized determinant of the same operator by a local term. In addition, we compute multiplicative anomalies for the zeta regularized determinant.

Supercharacter theory via the group determinant [PDF]
arXiv, 2020 Ferdinand Georg Frobenius is generally considered the creator of character theory of finite groups. This achievement came from the study of the group determinant, which is the determinant of a matrix coming from the regular representation. In this paper, we generalize several of Frobenius' results about the group determinant and use them find a new ...
