Abstract

Compared to scalar framelets, multiframelets have certain advantages, such as relatively smaller supports on generators, high vanishing moments, etc. The balancing property of multiframelets is very desired, as it reflects how efficient vector-valued data can be processed under the corresponding discrete multiframelet transform. Most of the literature studying balanced multiframelets is from the point of view of the function setting, but very few approaches are from the aspect of multiframelet filter banks. In this paper, we study structural characterizations of balanced dual multiframelets from the point of view of the Oblique Extension Principle (OEP). The OEP naturally connects framelets with filter banks, which makes it a very handy tool for analyzing the properties of framelets. With the OEP, we shall characterize compactly supported balanced dual multiframemets through the concept of balanced moment correction filters, which is the key notion that will be introduced in our investigation. The results of this paper demonstrate what essential structures a balanced dual multiframelet has in the most general setting, and bring us a more complete picture to understand balanced multiframelets and their underlying discrete multiframelet transforms., Comment: 20 pages. arXiv admin note: substantial text overlap with arXiv:2009.10309

Abstract

Background Urinary incontinence often occurs in women aged 40-60 years and contributes to a significant impact on women's physical health and quality of life. Objective To explore the prevalence and influencing factors of urinary incontinence and its impact on quality of life in women aged 40-60 years in Guizhou Province. Methods From June 2022 to January 2023, women aged 40-60 years who underwent health checkups in 10 hospitals in 7 regions of Guizhou Province were selected as the study subjects. A self-designed general data questionnaire was used to collect the basic data of the study subjects, and International Consultation on Incontinence Questionnaire-Female Lower Urinary Tract Symptoms (ICIQ-FLUTS) and Incontinence Quality of Life Measure (I-QoL) were used to determine the severity of urinary incontinence and the level of quality of life of the study subjects, respectively. Different types of incontinence, including stress incontinence, urge incontinence, and mixed incontinence, were determined according to the diagnostic criteria established by the International Continence Society (ICS). Multivariate Logistic regression analysis was used to explore the influencing factors of urinary incontinence, and explore the effects of different types and severity levels of urinary incontinence on patients' quality of life. Results A total of 3 000 questionnaires were distributed, and 2 966 valid questionnaires were collected, with a valid recovery rate of 98.9%. The prevalence of urinary incontinence among the 2 966 study subjects was 33.4% (991/2 966), including 20.1% (596/2 966) for stress incontinence, 2.0% (58/2 966) for urge incontinence, and 11.4% (337/2 966) for mixed incontinence. Multivariate Logistic regression analysis showed that physical exercise, menstrual status, parity, history of pelvic organ prolapse, perineal laceration, and lateral episiotomy were the influencing factors of stress incontinence (P

18. Generalized Matrix Spectral Factorization with Symmetry and Applications to Symmetric Quasi-Tight Framelets

Abstract

Factorization of matrices of Laurent polynomials plays an important role in mathematics and engineering such as wavelet frame construction and filter bank design. Wavelet frames (a.k.a. framelets) are useful in applications such as signal and image processing. Motivated by the recent development of quasi-tight framelets, we study and characterize generalized spectral factorizations with symmetry for $2\times 2$ matrices of Laurent polynomials. Applying our result on generalized matrix spectral factorization, we establish a necessary and sufficient condition for the existence of symmetric quasi-tight framelets with two generators. The proofs of all our main results are constructive and therefore, one can use them as construction algorithms. We provide several examples to illustrate our theoretical results on generalized matrix spectral factorization and quasi-tight framelets with symmetry., Comment: 37 pages, 36 figures

38. Discovering Knowledge-Point Importance from the Learning-Evaluation Data

Author

Guo, Hongfei, Yu, Xiaomei, Wang, Xinhua, Guo, Lei, Xu, Liancheng, and Lu, Ran

Abstract

As students in online courses usually show differences in their cognitive levels and lack communication with teachers, it is difficult for teachers to grasp student perceptions of the importance of knowledgepoints and to develop personalized teaching. Though recent studies have paid attention to this topic, existing methods fail to calculate the importance of every knowledge-point for each student. Moreover, some studies are based on expert analysis, are not data-driven, and hence, are inapplicable to largescale online scenarios. To address these issues, this article proposes a personal topic rank (PTR) as a solution, which links students and concepts to generate a personalized knowledge concept map. Then, the authors present a novel PTR method to calculate the importance of knowledge-points, wherein student mastery of knowledge-points, student understanding, and the knowledge-point itself are considered simultaneously. This article conducts extensive experiments on a real-world dataset to demonstrate that the method can achieve better results than baselines.
