Fault diagnosis of large-scale electric pumping and irrigation electromechanical equipment by integrating CWT and swin transformer

open access: yesFrontiers in Mechanical Engineering
This paper proposes a large-scale electromechanical equipment fault diagnosis framework that integrates continuous wavelet transform (CWT), Swin transformer, and cross attention. Firstly, CWT uses optimized complex Morlet wavelets (impact sharpness ratio

Comparative Evaluation of Hemodiafiltration, Hemoperfusion, and Standard Hemodialysis on Efficacy, Inflammatory Control, Dialysis Adequacy, and Safety in End‐Stage Renal Disease: A Prospective Observational Study

open access: yesTherapeutic Apheresis and Dialysis, EarlyView.
ABSTRACT Background Chronic micro‐inflammation in patients with end‐stage renal disease (ESRD) is a significant driver of cardiovascular complications and diminished quality of life. While standard hemodialysis (SHD) effectively manages small‐molecule clearance, its ability to remove medium‐to‐large uremic toxins—the primary catalysts of systemic ...

Evolution of physical and mechanical properties of municipal solid waste in a landfill with low kitchen waste content

open access: yesYantu gongcheng xuebao, 2023
The classified treatment of the municipal solid waste (MSW) will lead to a significant decline in the proportion of kitchen waste in landfills in China, which puts forward new requirements for the long-term safe operation of landfills.

An isoform of 14‐3‐3 protein regulates transbilayer lipid movement at the plasma membrane

open access: yesFEBS Letters, EarlyView.
Loss of 14‐3‐3ζ in CHO cells confers resistance to exogenous phosphatidylserine (PS) and impairs endocytosis‐independent inward flip‐flop of fluorescent PS at the plasma membrane. RNAi‐mediated knockdown reproduces this defect, while no additive effect is seen in ATP11C‐deficient cells.

Dimensionamento de motores para o bombeamento de água Sizing motors for water pumping

open access: yesEngenharia Agrícola, 2010
O dimensionamento de motores com potência acima da necessária acarreta maior custo inicial, menor rendimento e menor fator de potência. Desde 1996, que se fabricam no Brasil motores elétricos com fator de serviço maior do que a unidade, obedecendo a ...

Salmonella lipopolysaccharide‐containing supported lipid bilayers as platforms to study bacteriophage interactions

open access: yesFEBS Letters, EarlyView.
We present robust protocols for the preparation of supported lipid bilayers (SLBs) incorporating either Salmonella smooth LPS or outer membrane vesicles (OMVs). We use a combination of quartz crystal microbalance with dissipation (QCM‐D) and fluorescence microscopy to both characterize the SLBs of various compositions and to probe their interactions ...
