We present VisionFM, a foundation model pre-trained with 3.4 million ophthalmic images from 560,457 individuals, covering broad range of diseases, modalities, imaging devices, and demography. After pre-training, VisionFM provides to foster multiple artificial intelligence (AI) applications, such as disease screening diagnosis, prognosis, subclassification phenotype, systemic biomarker prediction, each application enhanced expert-level accuracy. The generalist outperformed ophthalmologists...
Underground subway platforms are among the world's busiest public transportation systems, but airborne transmission mechanism of respiratory infections on these has been rarely studied. Here, computational fluid dynamics (CFD) modeling is used to investigate airflow patterns and infection risks in an island platform under two common ventilation modes: Mode 1- both sides have air inlets outlets; 2- present at outlets middle. Under investigated scenario, structure characterized by jet human...
Abstract This paper describes the rheological behavior of Na+-montmorillonite suspensions in presence and absence different electrolytes (NaCl, KCl, LiCl) a polyethylene oxide type polymer under high pressure temperature conditions. Shear stress - shear rate flow curves were obtained for 5% (w/w) temperatures up to 120°C pressures 1000 Bar. The data was fitted both Bingham model Herschel-Bulkley model, from which corresponding properties derived. Results indicate that addition rise leads an...
Shanghuo(excessive internal heat) is a special organic state based on the concept of traditional Chinese medicine(TCM), commonly known as abnormal heating syndrome body in folks. With acceleration modern life rhythm and increase social competition pressure, emotional stress has become an important cause for spread Shanghuo symptoms. What's more, can impact physiological functions to onset, recurrence progression common diseases, harming health body. According long-term research findings,...
Transformer is an important equipment in power system, and its operational reliability affects the safety of whole system. As one main internal structures, it great engineering value to study influence winding defects on insulation performance. In this paper, a simulation model constructed by using finite element multiphysics size parameters actual converter transformer, four typical such as metal particles, corner rings, transformer oil burrs are simulated respectively, electric field...
Multiscale metrics such as negative Sobolev norms are effective for quantifying the degree of mixedness a passive scalar field advected by an incompressible flow in absence diffusion. In this paper we introduce mix norm that is motivated $H^{-1}$ general domain with no-flux boundary. We then derive explicit expression optimal maximizes instantaneous decay rate under fixed energy and enstrophy constraints. Numerical simulations indicate decays exponentially or faster various initial...
Flight target recognition (FTR) has always been a hot research topic in the field of pattern and machine vision. It is great significance for civil aviation safety, hazard early warning, many other fields. Radar Cross Section (RCS) can fully reflect electromagnetic scattering profile, motion polarization characteristics flight target, then widely used FTR. Most FTR methods are based on object-specific feature parameters distilling from RCS by statistical techniques, which demand high-quality...
We consider a fluid stirred by the locomotions of squirmers through it and generalize stochastic hydrodynamic model proposed Thiffeault et. al. [1, 2] to case in which swimmers move anisotropically random directions. A non-diagonal effective diffusivity tensor is derived with diffusive preference passive particle along any given direction can be computed provide more details phenomena beyond scalar statistics. further identify fraction from orthogonal decomposition drift-induced displacement...
Abstract Objective The prevalence of early-onset colon cancer (EOCC) among individuals below the age 50 has shown a marked upward trend in recent years. embryology, clinical symptoms, incidence, molecular pathways, and oncologic outcomes differ between right-sided left-sided cancers. However, differences have not been fully researched EOCC. Our study aims to develop validate prognostic nomograms predicting overall survival (OS) for EOCC different tumor locations based on Surveillance,...
Solar cells can improve their photovoltaic conversion efficiency and output performance through concentration, but due to the non-ideal nature of concentrators, uneven distribution light on surface cell have negative effects. This be reduced by adjusting ratio concentrator spot size area decrease non-uniformity illumination. Considering actual temperature effect, distribution, carrier generation rate, characteristics were studied using different coverage schemes. The study showed that under...
