Echocardiography (ECG) is the most common method used to diagnose heart failure (HF). However, its accuracy relies on experience of operator. Additionally, video format data makes it challenging for patients bring them referrals and reexaminations. Therefore, this study a deep learning approach assist physicians in assessing cardiac function promote standardization echocardiographic findings compatibility dynamic static ultrasound data.A spatio-temporal convolutional model r2plus1d-Pan...
Green hydrogen plays a vital role in facilitating the transition to sustainable energy systems, with stable and high-capacity offshore wind resources serving as an ideal candidate for large-scale green production. However, capacity of turbines continues grow, increasing size weight these systems pose significant challenges installation deployment. This study investigates application high-temperature superconducting (HTS) materials generator power conducting cables promising solution...
5-hydroxytryptophan (5-HTP), the direct biosynthetic precursor of neurotransmitter 5-hydroxytryptamine, has been shown to have unique efficacy in treatment a variety disorders, including depression, insomnia, and chronic headaches, is one most commercially valuable amino acid derivatives. However, microbial fermentation for 5-HTP production continues face many challenges, low titer/yield presence intermediate L-tryptophan (L-Trp), owing complexity activity heterologous expression...
This study presents an improved comprehensive atomization model for a pressure swirl atomizer. The integrates internal flow predictions, linear instability analysis of swirling annular liquid sheet, primary sub-model, and droplet velocity sub-model. Measurement data combined with the inviscid theory predict flow, providing sheet thickness at atomizer outlet. dispersion relation surface disturbances is obtained through analysis. A breakup predictive particle size distribution constructed...
The deepwater drilling riser is a very important and vulnerable connection between an offshore platform subsea wellhead. Under some certain complex marine environment operating conditions, the may drift beyond safe limitations or be driven away rapidly. In order to protect safety of platform, personnel equipment, it necessary implement emergency disconnection riser. Since stretched under normal connection, will perform recoil response combined effect elastic potential energy fluid (mud)...
Introduction: L-lysine is a bulk product. In industrial production using high-biomass fermentation, the high density of bacteria and intensity require sufficient cellular respiratory metabolism for support. Conventional bioreactors often have difficulty meeting oxygen supply conditions this fermentation process, which not conducive to improving sugar-amino acid conversion rate. study, we designed developed an oxygen-enhanced bioreactor address problem. Methods: This optimizes aeration mix...
Abstract Wutai Mountain is the highest mountain in Taihang Mountain‐chain, which one of important boundaries three grade physiognomy China. The study on its uplifting history confirming forming age physiognomy. We collected a series rock samples along two sections, from Beitai peak northwards and downwards to foot, other maximal altitude Changchengling region, Fuping county, eastwards foot. Then we selected 16 make apatite fission track study. histogram length distribution confined shows...
The increase in the use of ultrasound-guided interventional therapy for cardiovascular diseases has increased importance intraoperative real-time cardiac ultrasound image interpretation. We thus aimed to develop a deep learning-based model accurately identify, localize, and track critical structures lesions (9 kinds total) validate algorithm's performance using independent data sets.This diagnostic study developed collected from Fuwai Hospital between January 2018 June 2019. was validated...
A large amount of oil and gas has been discovered in the ultradeep reservoirs Shawan Sag, Junggar Basin. However, hydrocarbon phases are complex, controlling factors evolution have not studied, which important for exploration development. This study determined phase states Upper Wuerhe Formation (P3w) Well Zheng 10 Sag via components a pressure–volume–temperature (PVT) diagram. We used 1D basin modeling to simulate thermal maturity Lower (P2w) source rock, generated hydrocarbons, reservoir...
Hydrogen production from renewable energy sources is a crucial pathway to achieving the carbon peak target and realizing vision of neutrality. The hydrogen offshore superconducting wind power (HPOSWP) integrated systems, as an innovative technology in field, holds significant market potential promising development prospects. This technology, based on research into high-temperature generator (HTSG) characteristics electrolytic water (EWHP) converts (OWE) locally through electrolysis, with...
This paper summarizes the main sedimentary sequences of major cratonic basins during breakup Rodinia and assembly Gondwana extracts evolutionary stages Neoproterozoic around Paleo‐Pacific Ocean Iapetus tracts. During Rodinia, in blocks, such as Yangtze, Australia, Eastern American, Western Africa cratons, mostly experienced intracratonic rifting, drifting or passive continental margin, carbonate platform construction, foreland basin stages. The time rifting to transition Congo‐São‐Francisco...
Summary The study of vortex-induced vibration (VIV) characteristics deepwater drilling risers is great significance for correctly evaluating the risers’ fatigue life. Aiming to determine VIV response a riser under combined action heave motion floating platform and sea current, this established mechanical model governing equation crossflow vortex-parametric (CFVPV) based on Van der Pol wake oscillator Euler-Bernoulli beam. For model, discretized in time domain by applying finite element...
During deepwater drilling, the subsea wellhead will be subjected to dynamic loads transmitted from marine environment, floating drilling platform, riser, and blowout preventer (BOP). Therefore, complex responses induced, which seriously affect safety of wellhead. In this paper, considering effect auxiliary pipelines on a novel entire mechanical model platform–riser–BOP–subsea is established. By using finite-difference method, governing equations are solved. Finally, bending moment stress...
