Energy Consumption Minimization with SNR Constraint for Wireless Powered Communication Networks.

The article addresses the energy consumption minimization problem in wireless powered communication networks (WPCNs) and proposes a time allocation scheme, named DaTA, which is based on the Different Target Simultaneous Wireless Information and Power Transfer (DT-SWIPT) scheme such that the wireless station can share the remaining energy after transmission to the Hybrid Access Point (HAP) to those who have not transmitted to the HAP to minimize the energy consumption of the WPCN. In addition to proposing a new frame structure, the article also considers the Signal-to-Noise (SNR) constraint to guarantee that the HAP can successfully receive data from wireless stations. In the article, the problem of minimization of energy consumption is formulated as a nonlinear programming model.

Comorbid autoimmune diseases in patients with pemphigus: a nationwide case-control study in Taiwan.

Previous studies have proposed the association between pemphigus and several autoimmune diseases, but no large-scale study has been reported. To delineate the association between pemphigus and autoimmune diseases including psoriasis. A total of 1,998 patients with pemphigus and 7,992 control subjects were enrolled from the National Health Insurance Research Database in Taiwan from 1997 to 2010.

Cardiovascular comorbidities in patients with rosacea: A nationwide case-control study from Taiwan.

Background: Rosacea is a chronic inflammatory skin disease. Inflammation plays a prominent role in atherosclerosis and its complications.

Objective: We sought to investigate the associations of rosacea with cardiovascular disease risk factors and cardiovascular diseases from a nationwide population-based database.

Autoimmune disease comorbidities in patients with atopic dermatitis: a nationwide case-control study in Taiwan.

Background And Objectives: Atopic dermatitis (AD) is a chronic relapsing dermatitis of unknown etiology. It is thought that abnormal regulation of Th1 and Th2 is not only the major cause of AD, but also the vital pathogenesis of many autoimmune diseases. To date, no large-scale studies have been performed on the relationship between AD and autoimmune disease.
