Based on the VMS survey of the compact array antenna CA02, the effects of gravity deformation were examined in AT 39.3/115. The dominant cause of gain loss and beam distortion was identified to be the deformation of the main reflector surface with elevation. This report examines whether active displacements in the sub-reflector and/or feed might compensate for the aperture wavefront errors. All...

To reveal the intrinsic signal-to-noise ratio (SNR) of single-trial somatosensory-evoked potentials (SEP). SEP was recorded from 13 scoliosis patients during surgery. The power of SEP was estimated with least-square fitting to obtain the most accurate value and then to estimate the SNR of every trial of SEP. The SNR of cortical SEP from 13 cases presented individual difference among each other....

BACKGROUND Despite social gradients in adult smoking, the effects of socioeconomic position (SEP) on adolescent smoking is not well understood. This study examined effects of subjective SEP as well as the objective SEP on smoking among Korean adolescents. MATERIALS AND METHODS Data were obtained from the 2012 Korea Youth Risk Behavior Web-based Survey, a nationally representative sample of mi...

Evidence is lacking on whether the duration and timing of low socioeconomic position (SEP) across a person's life course may be associated with incidence of type 2 diabetes mellitus (T2D). The authors' objectives were to investigate associations between cumulative SEP and the incidence of T2D in the Framingham Offspring Study (n = 1,893; 52% women; mean baseline age = 34 years). Pooled logistic...

The authors’ objectives were to investigate associations between cumulative SEP and the incidence of T2D in the Framingham Offspring Study (n 1⁄4 1,893; 52% women; mean baseline age 1⁄4 34 years).

OBJECTIVES To examine the associations between socioeconomic position (SEP) and multidomain self-reported and objectively-assessed sedentary time (ST). DESIGN Cross-sectional. SETTING General population households in England. PARTICIPANTS 2289 adults aged 16-96 years who participated in the 2008 Health Survey for England. OUTCOMES Accelerometer-measured ST, and self-reported television ...

OBJECTIVES This study systematically compared accumulation, sensitive period, critical period and social mobility models relating life course socioeconomic position (SEP) and adult crystallised cognitive ability, which has not been comprehensively investigated. DESIGN Two prospective cohort studies. PARTICIPANTS Five thousand three hundred and sixty-two participants in the Medical Research ...
