To develop a rat model of type 2 diabetic mellitus that simulated the common manifestation metabolic abnormalities and resembled natural history certain diabetes in human population, male Sprague-Dawley rats (4 months old) were injected with low-dose (15 mg/kg) STZ after high fat diet (30% calories as fat) for two (L-STZ/2HF). The functional histochemical changes pancreatic islets examined. Insulin-glucose tolerance test, islet immunohistochemistry other corresponding tests performed data...

Feature selection and dimensionality reduction are important for the performance of wind turbine condition monitoring models using supervisory control data acquisition (SCADA) data. In this paper, an improved random forest algorithm, namely Simplification Random Forest (FS_RF), is proposed, which capable identifying features closely correlated with working conditions. The Euclidian distances employed to distinguish weight same feature among different samples, its importance measured by means...

The Shanghai Transport Committee has estimated that passenger traffic increased fivefold between 2005 and 2014, will continue to increase. At the same time, maintenance costs of Metro have about six times their original value. To ensure reliability, availability, maintainability safety (RAMS) in railways, equipment sometimes needs be upgraded; new technology is an effective way modernizing system. Condition monitoring techniques are considered a pragmatic approach improve RAMS railways....

For very large datasets, random projections (RP) have become the tool of choice for dimensionality reduction. This is due to computational complexity principal component analysis. However, recent development randomized analysis (RPCA) has opened up possibility obtaining approximate components on datasets. In this paper, we compare performance RPCA and RP in reduction supervised learning. Experiment 1, study a malware classification task dataset with over 10 million samples, almost 100,000...

Abstract Pediatric patients suffer from chronic pancreatitis (CP), especially those with diabetes mellitus (DM). This study aimed to identify the incidence of and risk factors for DM in pediatric CP. CP admitted our center January 2000 December 2013 were assigned (<18 years old) adult group according their age at onset Cumulative rates both groups calculated identified. The median follow-up duration whole cohort was 7.6 years. In these 2153 patients, 13.5% them pediatrics. mean diagnosis...

Text-guided image-to-video (I2V) generation aims to generate a coherent video that preserves the identity of input image and semantically aligns with prompt. Existing methods typically augment pretrained text-to-video (T2V) models by either concatenating noised frames channel-wise before being fed into model or injecting embedding produced encoders in cross-attention modules. However, former approach often necessitates altering fundamental weights T2V models, thus restricting model's...

Abstract In massive multiple‐input multiple‐output (MIMO) systems, most of the existing detection work mainly assumes that channel is additive white Gaussian noise (AWGN). However, this assumption difficult to apply practical communication scenarios. To end, paper proposes a message passing (MPD) algorithm with convolutional neural network (CNN) (denoted as iterative MPD‐CNN structure) under correlated channels, which helpful solve issue performance degradation in non‐ideal AWGN channels....
