Fully transparent indium gallium zinc oxide thin film transistors (IGZO TFTs) on glass substrate were fabricated by radio frequency magnetron sputtering at room temperature. The influence of oxygen plasma treatment technology on the characteristics of IGZO TFTs were analyzed. Before growing the source/drain electrodes, different power of oxygen plasma were used to treat the surface of the source/drain region. The experiment results suggest that the plasma treatment can improve the performance of device. Compared with the control group, the TFTs with O2 plasma treatment for 10 seconds and power of 150W show a better performance. The Ion/Ioff ratio was increased by an order of magnitude from 2.67×104 to 2.1×105, and the saturation mobility (μsat) was doubled from 0.54 cm2 V-1 s-1 to 1.1cm2 V-1 s-1. The sub-threshold swing (SS) is 0.42V/dec, and Ion/Ioff ratio is 2.1×105.

A 0.2-3.3 GHz 2.4 dB NF 45 dB Gain Current-Mode Front-End for SAW-less Receivers in 180 nm CMOS 用于180nm CMOS无saw接收器的0.2-3.3 GHz 2.4 dB NF 45 dB增益电流模前端

A CMOS fully differential current-mode frontend for SAW-less receivers is proposed. The noise-cancelling LNTA has a main path of the common-gate (CG) stage and an auxiliary path of the inverter stage. A current mirror is used to combine the signals from the main and auxiliary paths in current-mode domain. The stacked nMOS/pMOS configurations improve their power efficiency. Traditional stacked tri-state inverter as D-latch replaced by the discrete inverter and transmission gate enables a reduced supply voltage of divider core. LO generator based on the improved divider provides quarter LO signals to drive the proposed LNTA-shared receiver front-end. Simulation results in 180 nm CMOS indicate that the integrated receiver front-end provides a NF of 2.4 dB, and a maximum gain of 45 dB from 0.2 to 3.3 GHz. The inband and out-of-band IIP3 of 2.5 dBm and 4 dBm, are obtained, respectively.

In this work, the quantitative impact of variability in the low and high resistance state distributions of Hafnium oxide based RRAM on the prediction accuracy of deep learning neural networks is explored over a wide range of current compliance ranging from 2 to 500micro Ampere. The device power versus prediction accuracy trade-off trend is examined for such a wide range of compliance for the first time. The weights of one of the layers of the convolutional neural network (CNN) are represented by the floating point binary representation where the binary bits are configured using the RRAM resistance distribution data on an AlexNet platform.

In this letter, a high-performance electrically adjust-able current regulator is proposed on the LED-compatible AlGaN/GaN platform. The regulator features an electrical controlled gate and an integrated sensor, which could effectively feedback the cathode potential into the channel near the gate. Therefore, a large adjustable range of current regulating, more than 300 mA/mm, is achieved with a maximum ripple of 34.4 mA/mm. Compared with the conventional devices that just own sensor or p-GaN gate, the proposed regulator exhibits reasonable operation point and low current ripple in addition to the large-range electrically adjustable functionality. These features render the proposed regulator's notable potential in commercialization of high-density integrated LED components, charging stations and so on.

Multi-information Complementarity Neural Networks for Multi-Modal Action Recognition 多模态动作识别的多信息互补神经网络
Pub Date : 2019-10-01 DOI: 10.1109/ISNE.2019.8896415

Multi-modal methods play an important role on action recognition. Each modal can extract different features to analyze the same motion classification. But numbers of researches always separate the one task from the others, which cause the unreasonable utilization of complementary information in the multi-modality data. Skeleton is robust to the variation of illumination, backgrounds and viewpoints, while RGB has better performance in some circumstances when there are other objects that have great effect on recognition of action, such as drinking water and eating snacks. In this paper, we propose a novel Multi-information Complementarity Neural Network (MiCNN) for human action recognition to address this problem. The proposed MiCNN can learn the features from both skeleton and RGB data to ensure the abundance of information. Besides, we design a weighted fusion block to distribute the weights reasonably, which can make each modal draw on their respective strengths. The experiments on NTU RGB-D datasets demonstrate the excellent performance of our scheme, which are superior to other methods that we have ever known.
多模态方法在动作识别中起着重要的作用。每个模态可以提取不同的特征来分析同一运动分类。但大量的研究往往将一个任务与其他任务分离开来,导致多模态数据中互补信息的利用不合理。Skeleton对光照、背景和视点的变化具有较强的鲁棒性,而RGB在某些情况下,当存在其他对动作识别有较大影响的物体时,例如喝水和吃零食,表现更好。在本文中,我们提出了一种新的多信息互补神经网络(MiCNN)用于人类动作识别来解决这个问题。所提出的MiCNN可以同时从骨架和RGB数据中学习特征,以保证信息的丰度。此外,我们还设计了一个加权融合块来合理分配权重,使每个模态都能发挥各自的优势。在NTU RGB-D数据集上的实验证明了该方案的优异性能,优于我们已知的其他方法。

Liver region extraction in abdominal CT images is a very important research field, a method of liver segmentation based on region growing for automatic selection of seed points is proposed in this paper. Firstly, the original image is binarized, and the initial area of the liver is extracted by the maximum area measurement method; After that, the improved region growth algorithm was used to segment the liver, and the location of seed points was automatically obtained by finding the center of the maximum inscribed circle locked in the initial liver area, which was used as the basis for the selection of seed points; Finally, the segmented liver region is treated by morphological methods. The experimental results show that the approach effectively solves the problem of manually selecting seed points for regional growth, and can improve the efficiency and accuracy of seed point selection, which avoids the selection of seed points at the wrong positions such as edges or noise due to subjective factors.
肝脏区域提取是腹部CT图像中一个非常重要的研究领域,本文提出了一种基于区域生长的肝脏分割方法,用于种子点的自动选择。首先对原始图像进行二值化处理,采用最大面积测量法提取肝脏的初始面积;然后,利用改进的区域生长算法对肝脏进行分割,通过寻找锁定在初始肝脏区域内的最大内切圆的圆心,自动获得种子点的位置,作为种子点选择的依据;最后,对分割后的肝脏区域进行形态学处理。实验结果表明,该方法有效地解决了人工选择区域生长种子点的问题,提高了种子点选择的效率和准确性,避免了由于主观因素导致种子点选择在边缘或噪声等错误位置。
