In this randomized controlled study, 140 ULMCAD who underwent CABG were randomly assigned WERP group (n=70) or control care (CC) (n=70). During...

Cathepsin L (CTSL), a lysosomal cysteine proteinase, is primarily dedicated to the metabolic turnover of intracellular proteins. It involved in various physiological processes and contributes pathological conditions such as viral infection, tumor invasion metastasis, inflammatory status, atherosclerosis, renal disease, diabetes, bone diseases, other ailments. The coronavirus disease 2019 (COVID-19), with its rapid global spread significant mortality, has been worldwide epidemic since late...

Cloud storage service allows data owner to store their big in the cloud and provides access users. As server is not trustworthy, we cannot rely on conduct control. To protect security privacy, Attribute-Based Encryption (ABE) a promising technique for control storage, because it more direct policies. However, there are two dynamic issues, namely attribute revocation policy updating, that should be solved first before deploying ABE practice. In this paper, design attribute-based scheme, which...

Abstract As a global phenomenon, the theme of math anxiety has received increasing attention. The present study aimed to investigate relationship between and performance determine role arithmetic skill in two different tasks. Fifty-seven college freshmen were recruited perform comparison task calculation task. Only main effect was found on behavioral level. In task, participants with high (HMA) showed faster latencies greater amplitudes N1 longer P3b latency relative their counterparts low...

Variation in signal complexity is common among different species. Understanding why some species have evolved extensive call can offer insight into the evolution of complex signals. In this study, we investigated functions types a treefrog using network analysis, male playback experiments, and correlation analysis between properties body size. Our results show that treefrogs produce three kinds notes be combined to single-note as well composite calls. We also identified an intermediate note...

Edge computing is a research hotspot that extends cloud to the edge of network. Due recent developments in computation, storage and network technology for end devices, networks have become more powerful, making it possible integrate locator/identity separation protocol (LISP) into these networks. Accordingly, this paper, we introduce LISP routers at network, focusing primarily on delay problem mapping resolution cache updating with help computing. To solve problem, first analyze...

Human mobility prediction is essential for applications like urban planning and transportation management, yet it remains challenging due to the complex, often implicit, intentions behind human behavior. Existing models predominantly focus on spatiotemporal patterns, paying less attention underlying that govern movements. Recent advancements in large language (LLMs) offer a promising alternative research angle integrating commonsense reasoning into prediction. However, non-trivial problem...

Mammals suffer permanent hearing impairment from the loss of auditory hair cells due to their inability regenerate. In contrast, lower vertebrates exhibit extraordinary capacity for cell regeneration and restoration, but mechanisms remain unclear. Here we characterize single-cell atlas Xenopus laevis inner ear perform a comprehensive comparison with mouse model. An exceptionally conserved neuronal type is discovered. The results reveal that outer (OHCs) exist exclusively in mammals....

With the saturation of market and competition in e-commerce, focus offline new retail has gradually shifted from commodities to consumers. Although there have been some developments industry terms consumer analysis recent years, such as flow statistics based on non-visual sensors experience questionnaire, it is still difficult meet growing demand due limitations traditional technologies. To deal with problem, Smart Eye System (SES) proposed analyze characteristics evaluate consumers by...

Objective We aimed to evaluate oblique-axis in-plane (OA-IP) techniques for real-time ultrasound-guided internal jugular vein (IJV) cannulation. Methods retrospectively analysed 1065 patients who underwent ultrasound (US)-guided IJV recorded demographic characteristics of patients, success rate, access time, cannulation number attempts and the incidence acute complications. Results The overall rate procedure was 100% (n = 1605). In total, 1594 cases (99.3%) were successful at first attempt,...

Purpose: To investigate the impact of shoulder subluxation (SS) on peripheral nerve conduction and function hemiplegic upper extremity (HUE) in poststroke patients.Methods: Thirty post-stroke patients were selected (SS group: 15 patients, non-SS respectively).
