Self-rated health status as a predictor of death, functional and cognitive impairment: A longitudinal cohort study

open access: yes, 2006
Understanding the prognostic capacity of a simple measure of self-rated health (SRH) by older people becomes increasingly important as the population ages. SRH has been shown to predict survival, functional status and service use.

Keeping it in the family: the self-rated health of lone mothers in different European welfare regimes

open access: yes, 2014
This study examines whether health inequalities exist between lone and cohabiting mothers across Europe, and how these may differ by welfare regime. Data from the European Social Survey are used to compare self-rated general health, limiting longstanding

Increasing the rate of output for m sequences

open access: yesElectronics Letters, 1991
Summary: By using several linear feedback shift registers running in parallel, producing different phases of the same maximal length sequence or \(m\) sequence, it is possible to interleave the outputs to give the original \(m\) sequence, thus giving an exceedingly simple technique for the fast generation of \(m\) sequences.

Design and implementation of variable frequency sine wave output buck-boost inverter

open access: yes, 2016
Conventional inverters have pulse-width-modulated output with a fundamental component at the desired frequency and magnitude. These converters are usually buck type and therefore the DC link voltage limits the maximum 3-phase output voltage magnitude. As

Locality, loneliness and lifestyle: a qualitative study of factors influencing women's health perceptions

open access: yes, 2016
The contribution of women to the achievement of global public health targets cannot be underestimated. It is well evidenced that within families, women are a key influence on the health and well-being of their children and partners. However, geographical
