To solve the stability problem of capacitor-free LDO, the damping-factor-control(DFC) frequency compensation is adopted to enhance stability. The proposed LDO has been implemented in a 0.18um CMOS technology, and the active chip area is 220um*120um(Without PAD). The maximum load current of the LDO is 100mA. The LDO ensures stability over a range of load variations from 0 to 100mA.

A thread image measurement device is also designed for the experiment. In terms of algorithm, the current thread parameter measurement method based on machine vision is easily disturbed by dust, grease and other factors in the industrial measurement environment, which leads to higher image noises. In view of the above problems and based on the combination of machine vision and deep learning technology, this paper proposes a method of measuring external threads with high automation and certain anti-interference ability. Firstly, this paper adopts the U-Net model, and incorporates it with the Attention Augment mechanism and residual learning module to form AA ResU-Net model, so as to improve the ability of learning the features of the target.

However, the time-consuming calibration before every use reduces the convenience of P300 BCI. In recent years, researchers are increasingly concerning the studies on calibration-free P300 BCI. In this study, we designed an on-line updating classifier for recognizing P300 based on the fundament of reinforcement learning and developed a calibration-free P300 BCI system. The on-line updating classifier can be randomly initiated and quickly optimized by learning from the system feedback. The system uses the latest classifier to recognize P300, acquires the user's feedback, and calls an on-line updating algorithm to optimize the classifier. By this system, any user can start using P300 BCI without having to collect the training data. To verify this system, we recruited 7 volunteers as the subjects to participate in a brain-controlled Chinese Pinyin experiment based on this system. The mean accuracies of recognizing P300, Pinyin symbols and Chinese words in the on-line experiment were 84.69% and 80.55% respectively.

Some convolutional neural networks (CNN) have been applied to recognize biomarkers based on code-modulated visual-evoked potentials (c-VEP) for personal identification. However, the ordinary CNNs encountered difficulties in grasping the basic characteristics of c-VEP to achieve a satisfactory performance. In this study, we proposed a lightweight convolutional neural network (LCNN) to recognize the c-VEP biomarkers in the tasks of personal identification. LCNN is composed of two parallel sub-nets, which correspond respectively to two profiles of a c-VEP sample and both include two blocks. The two blocks both contain a two-step convolutional sequence. The LCNN model is fitted by minimizing the categorical cross-entropy loss function. The goal of LCNN is to specifically handle the Electroencephalogram (EEG) data in the tasks of personal identification based on c-VEP. We recruited 20 subjects to participate in our personal identification experiments based on c-VEP. In the EEG dataset of the 20 subjects, LCNN reached the recognition accuracy of 99%.

The novel Swarm Decomposition algorithm was then applied on the per-hour HRV data to extract the corresponding oscillatory components (HRV-OCs). The OCs represent the four bands in an HRV data, namely the ultra-low frequency (ULF), very-low frequency (VLF), low frequency (LF), and high frequency (HF). The training and classification process followed a leave-one-out scheme and was done for each per-hour HRV-OC. The highest prediction accuracy of LVEF was observed when using the VLF and HF components of HRV at an early morning hour (03-00-04:00 - average accuracy: 75.6%) and an evening hour (18:00-19:00 - average accuracy: 72.7%), respectively.

Specifically, the Squeeze and Excitation (SE) and Spatial Attention Module (SAM) blocks are fused to learn the dependency between features from the channel and spatial directions respectively. In order to capture the long-range dependencies between features, the features embedded with SE and SAM are further fused with Disentangled Non-Local block (DNL).

The three ultrasound multifeature maps of breast tumor are composed of direct energy attenuation coefficient (AC), standard deviation of image intensity (SD) and Rician distribution parameters (RD). From the above multifeature maps, high-throughput radiomics features were extracted, then sparse representation method was used for feature selection, and then support vector machine was used to predict the benign and malignant of breast tumors. Eight groups of comparative experiments were established by using ultrasound gray-scale image, single ultrasound feature map and two ultrasound feature maps. The results from 164 patients with breast tumor showed that the AUC, accuracy and sensitivity of the radiomics classification model with feature maps of AC, SD and RD can reach 93.61%, 93.94% and 100%, respectively.
