To investigate the value of platelet-to-lymphocyte ratio (PLR) and fibrinogen (Fib) in evaluating the severity of acute exacerbation of chronic obstructive pulmonary disease (AECOPD) in the elderly. Forty elderly patients with AECOPD admitted to the Department of Respiratory and Critical Care Medicine of our hospital from January 2020 to December 2022 were selected as AECOPD group. According to the severity of the disease, they were divided into grade I (n=9), grade II (n=17) and grade III (n=14). Forty elderly patients with stable chronic obstructive pulmonary disease (SCOPD) were selected as SCOPD group. The general data, PLR and Fib levels of each group were compared. Logistic regression model was used to analyze the independent risk factors of elderly AECOPD. The predictive value of PLR and Fib for elderly AECOPD was evaluated by receiver operating characteristic curve (ROC). The levels of PLR and Fib in peripheral blood of AECOPD group were higher than those of SCOPD group (P<0.05). The levels of PLR and Fib in elderly patients with AECOPD of different clinical grades were compared, and the differences were statistically significant (P<0.05). Grade III was the highest, followed by grade II, and grade I was the lowest. Logistic regression analysis showed that the odds ratios of PLR and Fib were 1.857 and 2.094, respectively, which were independent risk factors for AECOPD in the elderly (P<0.05). ROC curve analysis showed that the area under the curve of PLR, Fib and their combination in predicting AECOPD in the elderly was 0.862, 0.853 and 0.948, respectively, and the combination of the two had the highest predictive value (sensitivity 87.50 %, specificity 95.00 % ). The levels of PLR and Fib in peripheral blood are related to the severity of AECOPD in elderly patients, and the combination of the two has the highest diagnostic value for AECOPD in elderly patients.

In wiew of the problem that noise affects workpiece image segmentation and tracking, in this paper, an approach was proposed to address the problem with adaptive square transform. Firstly, the block of noise images was extracted from the noise image and the mean value of the block was subtracted. Then learning square transform with sparse level was fixed. Updating square transform level was done asthe sparse level of the next learning square transform. Finally iteratived learning square transform and sparse level update, and averaged at the denoising blocks’ locations in the image generate denoised image estimate. The experimental results show that the proposed method has better denoising performance. Compared with the K-SVD algorithm, the peak signal-to-noise ratio of the denoised image is about twice that of the K-SVD algorithm, and the denoising speed is 3.9 times that of the K-SVD algorithm.

Cloth patterns and complex pattern make difficult to detect defects in the manufacturing process. Thus,a learning-based Gabor filter in multi-style fabric defect detection is proposed. First, Gabor filters are used to filter multi-style cloth at different directions and scales and select the optimal filter scale. Then, the defect features are extracted by using digital image feature discriminant,the feature images are segmented, and a number of preferred feature information blocks are merged. Finally, the fused images are processed by binarized and morphological filtering. Experimental results show that the method performs effectively both in flaw detecting of multi-style cloth and in real-time performing. Compared with similar algorithms, the detection accuracy and time efficiency have a certain increase. [ABSTRACT FROM AUTHOR]

For the issue that the existing cloud resource scheduling scheme doesn’ t take into account the dynamic price of resources, this paper proposed a new task scheduling scheme under the convex price function. First, this scheme modeled the rent price of cloud resource as a convex function, and divided the task execution interval into multiple units. Then, it rescheduled the tasks in the low density interval to other intervals under satisfy the task deadline, which according to the task density in the sub interval, so as to make the tasks stack for execution. Finally, based on the properties of the convex price function, it allocated the maximum resource for each task with the maximum execution rate of the task, so that to get more preferential price and reduce the total cost of the leased resource. Experimental results show that the proposed scheme can effectively reduce the total cost of task execution. [ABSTRACT FROM AUTHOR]

Based on Generative Adversarial Networks (GANs), most current text-to-image generation algorithms focus on designing different attention generation models to improve the characterization and expression of image details. However, they ignore the discriminator􀆳s perception of key local semantics, so the generation models can easily generate poor image details to "fool" the discriminators. This paper designs a vocabulary-image discriminative attention module in the discriminators to enhance the discriminators􀆳 ability to perceive and capture key semantics, and drive the generation model to generate high-quality image details. Therefore, a discrimination-enhanced generative adversarial model (DE-GAN) is proposed. The experimental results show that, on the CUB-Bird dataset, DE-GAN achieves 4.70 on the IS index, which is 4.2% higher than the baseline model and achieves high performance. [ABSTRACT FROM AUTHOR]
