Accurate and automatic segmentation of medical images is a crucial step for clinical diagnosis analysis. The convolutional neural network (CNN) approaches based on the U-shape structure have achieved remarkable performances in many different image tasks. However, context information extraction capability single stage insufficient this structure, due to problems such as imbalanced class blurred boundary. In paper, we propose novel Context Pyramid Fusion Network (named CPFNet) by combining two...
Automated retinal layer segmentation of optical coherence tomography (OCT) images has been successful for normal eyes but becomes challenging with diseases if the morphology experiences critical changes. We propose a method to automatically segment layers in 3-D OCT data serous pigment epithelial detachments (PED), which is prominent feature many chorioretinal disease processes. The proposed framework consists following steps: fast denoising and B-scan alignment, multi-resolution graph...
Misalignment angle is an important error in the integration of strapdown inertial navigation system (SINS) and global positioning (GPS). Currently, popular methods for SINS/GPS integrated are based on ground velocity. There two major defects: 1) not all GPS receivers provide velocity outputs 2) contained outliers will degrade performance alignment methods. In this paper, in-motion coarse method using position loci proposed. First, observation vector with derived. Different from current...
Prostate cancer (PC) is one of the common malignant tumors male genitourinary system. Here, we constructed PTX@ZIF-8, which a metal-organic-framework-encapsulated drug delivery nanoparticle with paclitaxel (PTX) as model drug, and further modified synthesized peptide dimer (Di-PEG2000-COOH) onto surface PTX@ZIF-8 to prepare nanotargeted system (Di-PEG@PTX@ZIF-8) for treatment prostate cancer. This study investigated morphology, particle size distribution, zeta potential, loading,...
Background: Colorectal cancer (CRC) is one of the common malignant tumors. Chemotherapeutic agents represented by doxorubicin (DOX) are adjuvant therapies for patients with advanced CRC. However, DOX suffers from dose-dependent cardiotoxicity and myelosuppression due to a lack targeting specificity, which severely limits its clinical application. Methods: Herein, we constructed zeolitic imidazolate framework-8 (ZIF-8) modified novel peptide (LT peptide) deliver chemotherapeutic drug targeted...
Bias stability is an important performance indicator for MEMS gyroscopes. In this paper, a gyroscope zero rate output (ZRO) model under force-to-rebalance (FTR) closed-loop detection presented, and the effect of circuit phase delay various noises on ZRO analyzed. Based fact that two feedback forces in FTR system are insensitive to sense mode, while they sensitive drive method quickly calculating proposed, all-pass filter used realize one-time automatic compensation mode. The control...
This paper reports an effective and practical temperature compensation method for improving the performance of MEMS torsional accelerometer.

Abstract Detection and assessment of the integrity photoreceptor ellipsoid zone (EZ) are important because it is critical for visual acuity in retina trauma other diseases. We have proposed validated a framework that can automatically analyse 3D EZ optical coherence tomography (OCT) images. The images first filtered segmented into 10 layers, which located 7 th layer. For each voxel EZ, 57 features extracted principle component analysis performed to optimize features. An Adaboost classifier...
