For instance, in the study of Zeeberg et al. approximately 70% out of 216 MOH patients demonstrated a 50% reduction in headache frequency and intensity after treatment.
In some applications, points of a metric space have associated 'weights.' For instance, in the study of molecules, one can represent a molecule as a union of balls in Euclidean space [93, 94].
This would be in harmony with a general principle at work in the central nervous system, that of maximizing mutual information, which on the sensory side corresponds to a maximum of discrimination (and Fisher information; see [40]) and on the motor side to what has been called the "minimum variance principle", for instance in the study of ocular saccades or arm movements [41].
The Hankel determinant plays an important role, for instance, in the study of the singularities by Hadamard, see [[18], p. 329], Edrei [19] and in the study of power series with integral coefficients by Polya [[20], p. 323], Cantor [21], and many others.
This mapping technique could find several applications for instance in the study of aging, genotoxic drug screening, cancer, meiosis, radiation and oxidative DNA damage.
For instance, in the study of Claesson et al. [ 48], fewer women smoked, more women lived together with a partner, and depressive symptoms were measured with the Edinburgh Postnatal Depression Scale [ 49].
For instance, one in three exceptional achievers in all fields that have been studied lost a parent before the age of 15 (compared with 18% before modern medicine).
For instance, in the study by Hsu et al.
For instance, in a study of bereaved widows and widowers, Bonanno used a technique called verbal autonomic association.
For instance, in a study of people with schizophrenia, researchers found that subjects exhibited over-active cognitive emotion control.
This same assumption was made for instance in the global burden of disease study [ 40].
