TL;DR: An event-driven visualization mechanism fusing multimodal information for a large-scale intelligent video surveillance system that proactively helps security personnel intuitively be aware of events through close cooperation among visualization, data fusion, and sensor tasking is presented.
Abstract: Wide-area monitoring for a smart community can be challenging in systems engineering because of its large scale and heterogeneity at the sensor, algorithm, and visualization levels. A smart interface to visualize high-level information fused from a diversity of low-level surveillance data, and to facilitate rapid response of events, is critical for the design of the system. This paper presents an event-driven visualization mechanism fusing multimodal information for a large-scale intelligent video surveillance system. The mechanism proactively helps security personnel intuitively be aware of events through close cooperation among visualization, data fusion, and sensor tasking. The visualization not only displays 2-D, 3-D, and geographical information within a condensed form of interface but also automatically shows the only important video streams corresponding to spontaneous alerts and events by a decision process called display switching arbitration. The display switching arbitration decides the importance of cameras by score ranking that considers event urgency and semantic object features. This system has been successfully deployed in a campus to demonstrate its usability and efficiency for an installation with two camera clusters that include dozens of cameras, and with a lot of video analytics to detect alerts and events. A further simulation comparing the display switching arbitration with similar camera selection methods shows that our method improves the visualization by selecting better representative camera views and reducing redundant switchover among multiview videos.

TL;DR: Patients with COPD were at increased risk of herpes zoster relative to the general population and the relative risk of Herpes zoster was greatest for patients with COPd using oral steroids.
Abstract: Background Systemic inflammation and dysregulated immune function in chronic obstructive pulmonary disease (COPD) is hypothesized to predispose patients to development of herpes zoster However, the risk of herpes zoster among patients with COPD is undocumented We therefore aimed to investigate the risk of herpes zoster among patients with COPD Methods We conducted a cohort study using data from the Taiwan Longitudinal Health Insurance Database We performed Cox regressions to compare the hazard ratio (HR) of herpes zoster in the COPD cohort and in an age- and sex-matched comparison cohort We divided the patients with COPD into three groups according to use of steroid medications and performed a further analysis to examine the risk of herpes zoster Results The study included 8486 patients with COPD and 33 944 matched control patients After adjustment for potential confounding factors, patients with COPD were more likely to have incidents of herpes zoster (adjusted HR 168, 95% confidence interval [CI] 145-195) When compared with the comparison cohort, the adjusted HR of herpes zoster was 167 (95% CI 143-196) for patients with COPD not taking steroid medications The adjusted HR of herpes zoster was slightly greater for patients with COPD using inhaled corticosteroids only (adjusted HR 209, 95% CI 138-316) and was greatest for patients with COPD using oral steroids (adjusted HR 300, 95% CI 240-375) Interpretation Patients with COPD were at increased risk of herpes zoster relative to the general population The relative risk of herpes zoster was greatest for patients with COPD using oral steroids

TL;DR: Higher serum concentrations of PFOS were associated with an increase of carotid IMT in this cohort of adolescents and young adults, and subpopulation analysis showed the association between PFOS and CIMT was more evident and significant in females, non-smokers, subjects of age 12-19 years, BMI<24, and those with APOE genotype of E2 carrier and E3/E3.

TL;DR: The proposed protocol not only inherits the advantages of Srivastava et al.
Abstract: Radio Frequency Identification (RFID) based solutions are widely used for providing many healthcare applications include patient monitoring, object traceability, drug administration system and telecare medicine information system (TMIS) etc. In order to reduce malpractices and ensure patient privacy, in 2015, Srivastava et al. proposed a hash based RFID tag authentication protocol in TMIS. Their protocol uses lightweight hash operation and synchronized secret value shared between back-end server and tag, which is more secure and efficient than other related RFID authentication protocols. Unfortunately, in this paper, we demonstrate that Srivastava et al.'s tag authentication protocol has a serious security problem in that an adversary may use the stolen/lost reader to connect to the medical back-end server that store information associated with tagged objects and this privacy damage causing the adversary could reveal medical data obtained from stolen/lost readers in a malicious way. Therefore, we propose a secure and efficient RFID tag authentication protocol to overcome security flaws and improve the system efficiency. Compared with Srivastava et al.'s protocol, the proposed protocol not only inherits the advantages of Srivastava et al.'s authentication protocol for TMIS but also provides better security with high system efficiency.
