We present the design for an ultra-low latency and low energy Internet of Things (IoT) network inspired by emerging cooperative Non-Orthogonal Multiple Access (NOMA) wireless communication technique. The IoT model consists a source at center network, near device inside far outside network. is in proximity device, however. deploy as relay to assist device. assumed be node. As result, cannot forw...

backgrounds: there are controversies among surgeons about prophylaxis of deep vein thrombosis (dvt) in laparoscopic cholecystectomy. the aim of this study was the assessment of patients’ condition after laparoscopic cholecystectomy without any prophylactic measure. methods: 100 cases of laparoscopic cholecystectomy without dvt prophylaxis were followed by duplex scanning in the first postoperat...

Droplet digital polymerase chain reaction (ddPCR) is a partial PCR based on water-oil emulsion droplet technology. It is a highly sensitive method for detecting and delineating minor alleles from complex backgrounds and provides absolute quantification of DNA targets. The ddPCR technology has been applied for detection of many pathogens. Here the sensitive assay utilizing ddPCR for detection an...

This paper compares the performances of an ultra wideband (UWB) system in additive white Gaussian noise (AWGN) channel in presence of a pulsed jamming or a coloured Gaussian noise allocated in the UMTS-FDD (FDD = Frequency Division Duplex) uplink band. Several modulation schemes have been implemented in order to analyze the efficiency and the robustness of different UWB systems when the studied...

This paper presents a low-cost compact planar microstrip-fed monopole antenna and its four-element array design for ultra-wideband (UWB) wireless communication and target detection applications, respectively, operating in the frequency span of 3-11GHz. A prototype was fabricated and then measured based on optimal parameters. The results of reflection coefficient (S11) and radiation patterns are...

This paper demonstrates two methods which simultaneously undertake synchronization and ranging based on a time-of-arrival approach with bidirectional communication to bypass the need for accurate synchronous clocking. In order to alleviate multipath effects, Tomlinson-Harashima precoding and UWB signaling are used to measure the distance between pairs of sensors. The proposed schemes are shown ...
