BACKGROUND Despite providing insufficient medical evidence of the existence of a real cardiac condition, patients with non-coronary chest pain still interpret their pain incorrectly. The present study, therefore, sought to compare the irrational beliefs in non-coronary patients with mild chest pain against those with severe chest pain. METHODS A cross-sectional design was used. The statistica...

We introduce and study the number of tilings of unit height rectangles with irrational tiles. We prove that the class of sequences of these numbers coincides with the class of diagonals of N-rational generating functions and a class of certain binomial multisums. We then give asymptotic applications and establish connections to hypergeometric functions and Catalan numbers.

While in the univariate case solutions of linear recurrences with constant coeecients have rational generating functions, in the multivariate case the situation is much more interesting: even though initial conditions have rational generating functions, the corresponding solutions can have generating functions which are algebraic but not rational, and perhaps even non-algebraic. We start by an ...

Introduction: University students, as the future manpower resources, are of high importance for communities. One of the aspects to focus on is their mental health. The present study was conducted to determine the relationship between alexithymia, irrational beliefs, positive and negative emotions with mental disorders in students. Methods: There were 400 students, selected randomly through stra...

We describe Veech groups of flat surfaces arising from irrational angled polygonal billiards or irreducible stable abelian differentials. For irrational polygonal billiards, we prove that these groups are non-discrete subgroups of SO(2,R) and we calculate their rank.

OBJECTIVE Cardiac rehabilitation (CR) is routinely prescribed for patients with cardiovascular disease (CVD), but data indicate that 20% to 50% of patients do not adhere to CR. Studies have focused on the impact of depression on CR adherence, but results have been equivocal. Irrational health beliefs are related to adherence among diabetes patients, but have not been examined among cardiac pati...

We present a short new proof that the continued fraction of a quadratic irrational eventually repeats. The proof easily generalizes; we construct a large class of functions which, when iterated, must eventually repeat when starting with a quadratic irrational.
