High-robustness detection method for AC voltage measurement fault in MMC-HVDC systems

International Journal of Electrical Power & Energy Systems
Accurate grid AC voltage information is crucial for the stable control of Modular Multilevel Converter (MMC) systems. Due to limitations in design and manufacturing, AC voltage measurement is susceptible to failure, causing measured value to deviate from

Heterogeneous Exhumation Mechanisms in Neoproterozoic Collisional Metamorphism: P–T Constraints From Pelotas and Punta del Este Terranes, Southern Brazil and Uruguay

Geological Journal, EarlyView.
Petrography, thermobarometry, and pseudosection modelling reveal peak metamorphic conditions of 3–7.5 kbar and 520°C–800°C in Tonian‐Cryogenian orthogneisses of the Dom Feliciano Belt. Metamorphic field gradients of 27°C/km–39°C/km and variable exhumation mechanisms support correlation of these units as remnants of a Himalayan‐type Piratini Orogeny ...

Understanding the Symptom Burden of Complex Skull Base Tumors From the Patient's Perspective

Head &Neck, EarlyView.
ABSTRACT Background Symptom burden of skull base tumor (SBT) patients, especially those undergoing multimodality treatment, is poorly understood. We aim to understand symptom burden in this patient group using the core module the MD Anderson Symptom Inventory (MDASI).

Impedance-Based Methods for Detection of Voltage Sag Sources

RE&PQJ
The research reflects impedance-based methods for detection of voltage sag sources, whereas measured voltages and currents are treated as average functions, and also as instantaneous values. Evaluation of the discussed methods has been performed by applying extensive numerical simulations and field testing.

Somatic cell reprogramming for Parkinson's disease treatment

Ibrain, Volume 11, Issue 1, Page 59-73, Spring 2025.
The fundamental purpose of cell reprogramming to treat Parkinson's disease is to generate dopaminergic neurons (DAN) and do transplantation. There are two ways to accomplish this. One method is to induce cells into induced DA neurons (iDAN) directly or to induce cells into induced pluripotent stem cells and ultimately into iDAN in vitro. Another option

Triage Performance of FAM19A4/miR124‐2 Methylation: 18‐Month Follow‐Up Results From a Prospective Observational Study Within the Dutch Primary HPV‐Based Cervical Screening Program

International Journal of Cancer, EarlyView.
ABSTRACT DNA methylation analysis of the genes FAM19A4 and miR124‐2 has emerged as a promising triage strategy for high‐risk (hr) human papillomavirus (HPV)‐positive women in cervical screening. This study reports a prospective evaluation of the diagnostic accuracy of FAM19A4/miR124‐2 methylation in a large population‐based primary HPV‐based screening ...

Comparison of Relapse Risk Prediction Models During Active Surveillance in Stage I Seminoma: A Retrospective Multicenter Cohort Study

International Journal of Cancer, EarlyView.
ABSTRACT To improve the prediction of relapse for clinical stage I seminoma, we aimed to validate the Boormans model (incorporating tumor size, rete testis invasion, and lymphovascular invasion) against the conventional classification (tumor size > 4 cm/rete testis invasion).

Complicated Acute Appendicitis Conservatively Treated in Two Patients With Crohn's Disease: The Role of Intestinal Ultrasound and Contrast‐Enhanced Ultrasound

Journal of Clinical Ultrasound, EarlyView.
Intestinal ultrasound and contrast‐enhanced ultrasound were used to diagnose, monitor, and guide conservative treatment of complicated acute appendicitis in two patients with Crohn's disease. Serial imaging enabled early identification of treatment response, allowing long‐term surgery‐free outcomes.

Deep‐Learning Based Contrast Boosting: A Multi‐Center Multi‐Reader Study on Clinical Performance With Standard Contrast Enhanced Brain MRI

Journal of Magnetic Resonance Imaging, EarlyView.
ABSTRACT Background Gadolinium‐based contrast agents are used in brain MRI to improve the visualization of disorders and improve the delineation of lesions. Higher doses of GBCAs can improve lesion sensitivity but may have safety implications, particularly in light of recent findings on gadolinium retention and deposition.

Australia's Three System Approach to Mammographic Image Quality Assessment

Journal of Medical Radiation Sciences, EarlyView.
Mammographic image evaluation in Australia remains constrained by the use of fragmented, subjective, and largely unevaluated systems. The continued use of the Perfect (P), Good (G), Moderate (M), Inadequate (I) (PGMI) image evaluation system (IES) framework despite concerns around its validity and reliability reflects a perceived practical utility and ...
