We present results from a multiwavelength study of the blazar PKS 1954–388 at radio, UV, X-ray, and gamma-ray energies. A RadioAstron observation at 1.66 GHz in June 2012 resulted in the detection of interferometric fringes on baselines of 6.2 Earth-diameters. This suggests a source frame brightness temperature of greater than 2 × 1012 K, well in excess of both equipartition and inverse Compton limits and implying the existence of Doppler boosting in the core. An 8.4-GHz TANAMI VLBI image, made less than a month after the RadioAstron observations, is consistent with a previously reported superluminal motion for a jet component. Flux density monitoring with the Australia Telescope Compact Array confirms previous evidence for long-term variability that increases with observing frequency. A search for more rapid variability revealed no evidence for significant day-scale flux density variation. The ATCA light-curve reveals a strong radio flare beginning in late 2013, which peaks higher, and earlier, at higher frequencies. Comparison with the Fermi gamma-ray light-curve indicates this followed ~ 9 months after the start of a prolonged gamma-ray high-state—a radio lag comparable to that seen in other blazars. The multiwavelength data are combined to derive a Spectral Energy Distribution, which is fitted by a one-zone synchrotron-self-Compton (SSC) model with the addition of external Compton (EC) emission.
Introduction: The Medical University of South Carolina (MUSC) hospital implemented an inpatient opt-out smoking-cessation service where smokers received a mandatory smoking-cessation consult and phone follow-up within 1-month post-discharge.
Aim: To examine predictors of patients who opted-out of bedside counselling or follow-up phone calls.
Methods: Eligible adult cigarette smokers admitted to the MUSC hospital were enrolled in the programme. Opting-out of bedside consult or follow-up calls were assessed separately using log-linear modelling where predictors included patient demographics, length of hospitalisation, insurance type, smoking history, and motivation/confidence to quit.
Results: Of the 38,758 admitted patients (February 2014–May 2015), 6,684 reported currently smoking and were automatically referred to bedside-consult. Approximately 26% of smokers made contact with the counselor, most of whom (83%) accepted the consult. Amongst patients eligible for post-discharge follow-up (n = 3485), 49% responded to the calls. Those who opted-out of the bedside-consult were mostly males (RR = 1.29). Those who did not respond to follow-up calls were younger age (RR = 1.33), with Medicaid/no insurance (RR = 1.17), and had not received a bedside consult (RR = 1.32).
Conclusions: An opt-out smoking-cessation programme was feasible and acceptable to most patients and was able to reach 65% of eligible smokers; 17% opted-out of bedside counselling; <1% asked to be removed from further phone calls.
A preliminary orbit has been derived for the high luminosity, 27-d classical Cepheid T Mon. Velocities for the hot companion have been measured from an HST GHRS spectrum and 3 IUE spectra. The companion velocities are inconsistent with binary orbital motion and it is likely that the companion is itself a short period binary. The HST spectrum also shows that the companion is a chemically peculiar star, probably magnetic.
