Background The soluble cluster of differentiation 14 (or presepsin) is a free fragment of glycoprotein expressed on monocytes and macrophages. Although many studies have been conducted recently, the diagnostic performance of presepsin for sepsis remains debated. We performed a systematic review and meta-analysis of the available literature to assess the accuracy of presepsin for the diagnosis of...
This paper presents a low power high sensitivity RF power detector (PD) for multi-mode active tags. To achieve low power consumption and large detection range, two-branch common-source-type MOSFET transistors biased in subthreshold region are used. This power detector produces the mode-enabled signals to the multi-mode active tag according to the different received RF power. Therefore, the multi-mode...
An area-efficient digitally-assisted DC canceling loop is presented for high sensitivity single-chip UHF RFID readers. The proposed loop suppresses the DC blocker in RFID receivers by 41 dB with the aid of negative feedback. A delta-sigma modulator with 67dB dynamic range is implemented in the loop to enhance the sensitivity of the receiver. A reconfigurable digital loop filter with low cut off frequency...
This article examines the relationship between psychological contract of knowledge workers and their turnover intention. In addition, the impact of equity sensitivity on psychological contract breach perception and turnover intention is included in our study. Following prior research, relational psychological contract and transactional psychological contract are two key dimensions of knowledge workers'...
A passive Ultra-High Frequency (UHF) Radio Frequency Identification (RFID) based Real Time Locating System (RTLS) is presented in the paper. For the validation, a reader has been developed and complemented with a tag modulator to form a complete UHF RFID-based real time locating system focused on backscattering communication. PN sequences have been used to measure the TOA and estimate the distance...
