Energy-efficient precoding in multicell networks with full-duplex base stations

© 2017, The Author(s). This paper considers multi-input multi-output (MIMO) multicell networks, where the base stations (BSs) are full-duplex transceivers, while uplink and downlink users are equipped with multiple antennas and operate in a half-duplex mode. The problem of interest is to design linear precoders for BSs and users to optimize the network’s energy efficiency. Given that the energy efficiency objective is not a ratio of concave and convex functions, the commonly used Dinkelbach-type algorithms are not applicable. We develop a low-complexity path-following algorithm that only invokes one simple convex quadratic program at each iteration, which converges at least to the local optimum. Numerical results demonstrate the performance advantage of our proposed algorithm in terms of energy efficiency

The use of modified Mindfulness-based Stress Reduction and Mindfulness-based Cognitive Therapy programme for family caregivers of people living with dementia: a feasibility study

PURPOSE: The aim of this study was to investigate the feasibility and preliminary efficacy of a modified Mindfulness-Based Stress Reduction (MBSR) programme and Mindfulness-Based Cognitive Therapy (MBCT) programme for reducing the stress, depressive symptoms, and subjective burden of family caregivers of people with dementia (PWD). METHODS: A prospective, parallel-group, randomized controlled trial design was adopted. Fifty-seven participants were recruited from the community and randomized into either the modified MBSR group (n = 27) or modified MBCT group (n = 26), receiving seven face-to-face intervention sessions over 16 weeks. Various psychological outcomes were measured at baseline (T0), immediately post-intervention (T1), and at the 3-month follow-up (T2). RESULTS: Both interventions were found to be feasible in view of the high attendance (over 70.0%) and low attrition (3.77%) rates. The mixed ANOVA results showed positive within-group effects on perceived stress (p = .030, Cohen's d = .54), depressive symptoms (p = .002, Cohen's d = .77), and subjective caregiver burden (p < .001, Cohen's d = 1.12) in both interventions across the time points, while the modified MBCT had a larger effect on stress reduction, compared with the modified MBSR (p = .019). CONCLUSIONS: Both the modified MBSR and MBCT are acceptable to family caregivers of PWD. Their preliminary effects were improvements in stress, depressive symptoms, and subjective burden. The modified MBCT may be more suitable for caregivers of PWD than the MBSR. A future clinical trial is needed to confirm their effectiveness in improving the psychological well-being of caregivers of PWD
