Measures of frailty in population-based studies: An overview

Although research productivity in the field of frailty has risen exponentially in recent years, there remains a lack of consensus regarding the measurement of this syndrome. This overview offers three services: first, we provide a comprehensive catalogue of current frailty measures; second, we evaluate their reliability and validity; third, we report on their popularity of use

Excited state dipole polarizabilities and moments by solvent spectral frequency shifts: P-Benzoquinone, anthraquinone and 2, 3-Dichloro-5, 6-Dicyno-P-Benzoquinone

Solvent spectral frequency shifts have been used to investigate the structural and molecular properties of P-benzoquinone (PQ), anthraquinone (AQ) and 2, 3-dichloro-5,6-dicyano-pbenzoquinone (DDPQ). The spectral behaviours, in terms of transition energies and intensities, electric dipole moment and polarizabilities in excited states, are interpreted in terms of symmetries and molecular structures of these compounds
