In the field of bearing fault diagnosis, it is difficult to obtain a large amount labeled data for training, and therefore easy overfit model, which makes less robust generalizable. To address this problem, article offers novel semi-supervised contrastive learning (SSCL) method based on multiscale attention (MSA) mechanism multitarget (MCL) rolling diagnosis under limited samples. First, proposed SSCL utilizes improved MCL pretrain model as means capturing potentially generic features in...
While new buildings continue to emerge in the process of urbanization, historical buildings, as valuable legacies carrying national memory, play an important role urban landscape. Previous studies have shown that color harmony is a crucial factor coordinating landscapes. However, evaluation historic areas and lacks effective quantitative standards, often overlooking factors such complementary compatibility analogous colors. This study aims build method evaluate through street view...
Abstract An improved semi-empirical relationship for cluster radioactivity half-lives is proposed by introducing an accurate charge radius formula and analytic expression of the preformation probability. Moreover, daughter nuclei around 208 Pb or its neighbors 12 C half-life 114 Ba are calculated within relationship. It shown that accuracy new significantly compared to predecessor. In addition, experimentally unavailable trans-lead trans-tin predicted formula. These predictions might be...
Perceptual Video Compression (PVC) is a promising approach to enhancing compression efficiency. The Human Visual System (HVS) possesses many important perceptual characteristics, which can be utilized further enhance encoding efficiency without significantly degrading quality. This paper addresses the issue that existing video methods have not fully leveraged HVS characteristics by proposing scheme, SJ-PVC, uses Just Noticeable Distortion (JND) estimation model based on characteristics....
Tip vortex cavitation not only impacts the hydrodynamic performance of a propeller but also results in vibrations, noise, and erosion. In this study, effect blade number on tip is investigated using computational fluid dynamics (CFD) methods. Numerical simulation performed regarding four model propellers with numbers varying from one to four. These have same geometry as E779A propeller. Large eddy (LES) Schnerr–Sauer are used solve local mesh refinement according spiral trajectory. The...
This study attempted to provide further understanding of the association between walkability and urban design qualities in Xi'an, China. The novelty this paper is employ street view image data predict people's perceptions by constructing deep convolutional neural networks. In general, our results confirm relationship perceived a mixed area modern traditional cityscapes forms. Specifically, most dominant variable complexity, which has both positive negative impacts, imageability transparency...
We describe a manual prechop technique to divide the nucleus using cystotome. In cystotome-assisted technique, after capsulorhexis, surgeon-bent cystotome is inserted into lens while Nagahara chopper set around equator. The and are then brought together in center create bisecting crack nucleus, dividing it cleanly 2 hemispheres.No author has financial or proprietary interest any material method mentioned.

The status quo, development trend, necessity are explored its potential applications is analyzed. Based current practical level technology, by...
Intelligent Fault diagnosis technology can quickly and effectively extract features from data provide accurate results, which is vital to the normal operation of machinery. In this paper, a novel method based on semisupervised contrast learning (SSCL) intelligent fault techniques proposed for rolling bearing with nonstationary limited-labeled characteristics. SSCL model, multi-scale convolution structure introduced capture richer diagnostic information at different scales. Meanwhile,...
Sound source localization (SSL) determines the position of sound sources using multi-channel audio data. It is commonly used to improve speech enhancement and separation. Extracting spatial features crucial for SSL, especially in challenging acoustic environments. Previous studies performed well based on long short-term memory models. Recently, a novel scalable SSM referred as Mamba demonstrated notable performance across various sequence-based modalities, including speech. This study...
e22005 Background: Recurrent respiratory papillomatosis (RRP) is a human papillomavirus (HPV) driven benign neoplasm, affecting larynx, trachea, and even lung, leading to voice disorders, airway obstruction, post-obstructive pneumonia. Currently, there no curative therapy for RRP.Patients require frequent debulking operations symptomatic palliation. However, several case reports documented promising results on inhibition of vascular endothelial growth factor (VEGF) by systemic administration...
