Sensors, Vol. 19, Pages 4521: Energy-Efficient UAV-Enabled MEC System: Bits Allocation Optimization and Trajectory Design Sensors doi: 10.3390/s19204521 Authors: Linpei Li Xiangming Wen Zhaoming Lu Qi Pan Wenpeng Jing and Zhiqun Hu The unmanned aerial vehicle (UAV) enabled mobile edge computing (MEC) system is attracting a lot of attentions for the potential of low latency and low transmission energy consumption, due to the advantages of high mobility and easy deployment. It has been widely applied to provide communication and computing services, especially in Internet of Things (IoT). However, there are still some challenges in the UAV-enabled MEC system. Firstly, the endurance of the UAV is limited and further impacts the performance of the system. Secondly, mobile devices are battery-powered and the batteries of some devices are hard to change. Therefore, in this paper, a UAV-enabled MEC system in which the UAV is empowered to have computing capability and provides tasks offloading service is studied. The total energy consumption of the UAV-enabled system, which includes the energy consumption of the UAV and the energy consumption of the ground users, is minimized under the constraints of the UAV’s energy budget, the number of each task’s bits, the causality of the data and the velocity of the UAV. The bits allocation of uploading data, computing data, downloading data and the trajectory of the UAV are jointly optimized with the goa...

This study aimed to understand family communication and overall well-being of young adults in the context of familial opioid misuse using the family systems framework. Methods: A cross-sectional, mixed-methods, online survey of young adults aged 18 to 30 years (n=137) was conducted. A cluster analysis was performed based on family organization and structural characteristics. MANCOVA was utilized to compare groups identified using the cluster analysis in terms of (1) family’s belief about opioid misuse, (2) worry regarding opioid misuse, (3) family communication, and (4) overall well-being of young adults. Results...

Background and Aim: Controlling the symptoms of opioid withdrawal syndrome is important for the treatment of opioid addiction. There is very limited evidence on the effectiveness of pregabalin on opioid withdrawal syndrome. The present study examines the effectiveness of pregabalin in reducing opioid withdrawal symptoms. Methods: This double-blind clinical-trial was conducted on noninjecting opioid users diagnosed with opioid dependence and referred to the Addiction Treatment Center of Khorshid Hospital in Isfahan, Iran, in 2015 and 2016. The patients were divided into intervention and control groups, and both groups ...

This article reports an integrative review of seven trials carried out from 2007 to 2016, investigating the use of TMS on subjects abusing cocaine. The analysis was categorized into 5 different topics (1) area of intervention; (2) hemisphere; (3) number of pulses and intensity; (4) safety and adverse effects; and (5) other outcomes. Most of the trials found promising results of craving and/or use reduction with repetitive TMS (rTMS). Future interventions should consider the use of TMS as part of rehabilitation therapies.

Conclusions: These findings show that in Brazil problems related to alcohol use by the elderly remain relatively unknown. There was a high heterogeneity of methodologies in the studies, making it difficult to summarize the findings and produce prevalence estimates for the different patterns of consumption. More homogenous studies using similar definitions of patterns of alcohol consumption are required to allow comparisons to be made between different Brazilian regions and other countries.

Conclusions: A change was detected in the profile of treatment-seeking crack cocaine users over the past 2 decades. Current patients appear to be older and use the drug more chronically, in addition to having a higher level of schooling and lower unemployment rates when compared with 1997 users.

Objectives: For patients with opioid addiction seeking treatment, an effective option is Medication-assisted Treatment (MAT). In Albuquerque, the city with the greatest number of people who use opioids in New Mexico, the demand for MAT exceeds the number of patients receiving treatment. The authors hypothesized that a primary factor in patients’ ability to access treatment is clinic payment options, rather than the traditionally cited availability of providers. Methods: The authors conducted a survey assessing payment methods and corresponding availability in MAT programs for 53 of Albuquerque’s ~70 provid...
