CYFRA 21-1 was reported as the best concordance with NSCLC response, which has considerable potential for early diagnostic and prognosis of NSCLC. However, current methods for CYFRA 21-1 detection suffered from labor-intensive steps, low sensitivity, and high cost. Here we proposed a CMOS-compatible silicon nanowire field-effect-transistors (SiNW-FETs) with integrated PDMS microfluidic sample delivery system for ultrasensitive, label-free, and real-time detection of CYFRA 21-1. The nanosensors demonstrated a high sensitivity of CYFRA 21-1 as low as 1fg/mL, as well as good selectivity for other lung cancer biomarker CEA. © 14CBMS.

In the information transmission process of Smart Grid, the collection and transmission of power consumption data of the massive users are very important. The data can be classified into the periodic and the alarm data. Different types of data are different in terms of their priority, reliability and real-time, and the alarm data has more rigid requirements of priority, real-time and reliability. Based on the characteristics of the data transmitted by smart grid and the QoS requirement, a new hybrid MAC protocol, HTC-MAC(Hybrid TDMA/CSMA MAC) protocol is proposed. Based on TDMA /CSMA and their combination, this protocol proposes an alarm priority function(APF) and a node clustering method to allocates the resources dynamically, in order to reduce the transmission delay and data loss. Simulation results show that the protocol has a good performance in reducing packet loss rate and network communication delay.

According to the demand of water quality automatic monitoring in many large or medium reservoirs, we proposed an on-line water quality monitoring system. It is composed of wireless sensor networks and an embedded monitoring platform. We built a novel early-warning model to well adapt to the regular pattern of water quality change in the reservoirs. As a result, an Android application with outstanding control experience is achieved for real-time monitoring, water pollution early warning and water quality comprehensive assessment. Experimental results show that the system can work stably for a long time and provide accurate monitoring information continuously. It can also detect the abnormal signals of water quality in time and alarm. The system efficiently satisfies the requirement of water quality on-line automatic monitoring. © (2014) Trans Tech Publications, Switzerland.

Abnormal Visible Luminescence Mechanism of Tb3+-Yb3+ Codoped SiO2-Al2O3-CaF2 Glass Studied by Time-Resolved Spectra

The upconversion energy transfer mechanism in Tb³⁺-Yb³⁺ co-doped SiO₂-Al₂O₃-CaF₂ glass is investigated by time-resolved spectra. The effect of donor ion Yb³⁺ is involved in the dynamic decay behavior of acceptor ion Tb³⁺, which provides direct proof for the energy transfer from Yb³⁺ to Tb³⁺. The pump power dependence curves show that the upconversion luminescence is a two-photon process. The measured decay curves of the ⁵D₄ state (Tb³⁺) contain two parts: a slow decay process corresponding to its radiation, and a fast one with a decay parameter approximately twice the lifetime of the ²F_5/2 state (Yb³⁺). The fast decay process is contradictory to the generally accepted cooperative sensitization upconversion rate equation model. Since the effect of the host environmental is excluded by comparative experiments, we believe that there should be another energy transfer mechanism in Tb³⁺-Yb³⁺ co-doped SiO₂-Al₂O₃-CaF₂ glass in addition to the cooperative sensitization process.

Herein, we describe a novel approach for rapid, label-free and ultrasensitive detection of Hepatitis B virus (HBV) DNA by applying rolling circle amplification (RCA) based on silicon nanowire field-effect transistor (SiNW-FET). Optical lithography and anisotropic self-stop etching were employed to guarantee low cost batch production for SiNWs. The RCA reaction created a long single-stranded DNA (ssDNA) product and thus enhanced the electronic responses of SiNW significantly. The ultrahigh sensitivity for 1 fM HBV DNA detection and high specificity for single-nucleotide polymorphism discrimination were achieved. © 14CBMS.

A trench gate SOI LDMOS with an oxide trench in the drift region and a trench source plate (TG-LDMOS) is proposed to obtain a high breakdown voltage (BV) and low specific on-resistance (Rsp) simultaneously. The oxide trench extends the drift region in the vertical direction and reshapes the electric field, resulting in reduced cell pitch and Rsp. The trench source plate extends to the buried oxide layer (BOX) further enhances the RESURF effect and also works as a dielectric isolation trench. BV of 111V and Rsp of 0.87mω·cm2 are obtained for the TG-LDMOS with 3μm cell pitch. Compared with conventional LDMOS (C-LDMOS), Rsp of the TG-LDMOS decreases by 63.8%, the transconductance(gm) increases by 8.3% and the switching delay decreases by 32% at the same BV. Furthermore, the figure-of-merit (FOM=BV2/Rsp) of the TG-LDMOS equals to 14.6MW/cm2, exhibiting 172.7% improvement than that of C-LDMOS. © 2014 IEEE.

In this paper, 600V LDMOS and LIGBT on thin SOI with improved field oxide (FOX) were fabricated. The dependence of the off-state breakdown voltage on the implant dose in the drift region and the on-state characteristics were measured. Total ionizing dose (TID) effects on LDMOS and LIGBT were studied experimentally. The threshold voltage shift and leakage current induced by 60Co gamma irradiation under different dose and bias conditions were compared. © 2014 IEEE.
