A Comparative Study of the Mode-Decomposed Characteristics of the Asymmetricity of a Vortex Rope with Flow Rate Variation

Symmetry
In hydro turbines, the draft tube vortex rope is one of the most crucial impact factors causing pressure pulsation and vibration. It is affected by operating conditions due to differences in the flow rate and state and can be symmetric or asymmetric along the rotational direction. It may influence the stability of draft tube flow.

MMS Observations of the Energetic Particles Within Kelvin‐Helmholtz Waves at the Boundary of the 10 May 2024 Coronal Mass Ejection (CME)

Geophysical Research Letters, Volume 53, Issue 13, 16 July 2026.
Abstract On 10 May 2024, Earth was hit by a CME that drove the largest geomagnetic storm in 20 years. Multi‐spacecraft observations previously showed that the ∼100 nT north‐south IMF bz ${b}_{z}$ variation was driven by Kelvin‐Helmholtz waves with wavelength ∼250 RE ${R}_{E}$ and reconnection jets in the ±z $\pm z$‐direction (Nykyri, 2024a, https://doi.

Explainable machine learning for patient‐specific quality assurance in intensity‐modulated radiotherapy based on anatomical structures

Journal of Applied Clinical Medical Physics, Volume 27, Issue 7, July 2026.
Abstract Background Patient‐specific quality assurance (PSQA) plays a pivotal role in intensity‐modulated radiotherapy (IMRT) to ensure accurate dose delivery. However, conventional measurement‐based PSQA approaches are labor‐intensive and provide limited insight into the underlying factors contributing to variations in gamma passing rates (GPRs ...

Evaluation of CSF and plasma tau species as fluid surrogate candidates for tau PET in prodromal to moderate Alzheimer's disease

Alzheimer's &Dementia, Volume 22, Issue 7, July 2026.
Abstract INTRODUCTION Positron emission tomography (PET) is a valuable tool for assessing tau pathology in Alzheimer's disease (AD), but it is not widely accessible. Clarifying the relationship between fluid tau species and tau PET in AD may allow for the identification of fluid biomarkers that could serve as more accessible surrogates for tau PET ...

Oxidative Stress‐Induced Expression Levels of PXDN and NF‐κB in Type 2 Diabetic Patients With Nephropathy

Endocrinology, Diabetes &Metabolism, Volume 9, Issue 4, July 2026.
PXDN expression is markedly upregulated in diabetic nephropathy and, versus NF‐κB and oxidative stress markers, shows superior diagnostic performance (AUC 0.79; 90% specificity), supporting PXDN as a sensitive, specific non‐invasive biomarker for early DN.
