Analysis of transformer bias vibration based on "magnetic-mechanical" coupling

Journal of Applied Science and Engineering
The large-scale application of flexible DC power transmission technology leads to DC bias in transformer cores, and the vibration analysis of transformers under the influence of DC bias is becoming a hot topic.

Investigation of Microstructural, Mechanical, and Tribological Properties of TiC and MWCNT Reinforced Hot-Pressed Scalmalloy^® Hybrid Composites

Lubricants
In this study, hybrid composite materials were fabricated using a Scalmalloy® matrix with fixed multi-walled carbon nanotube (MWCNT, 0.8%) content and varying titanium carbide (TiC; 5%, 10%, 15%) reinforcements via the hot-pressing method.

Randomness in Classical Mechanics and Quantum Mechanics [PDF]

Foundations of Physics, 2010
The Copenhagen interpretation of quantum mechanics assumes the existence of the classical deterministic Newtonian world. We argue that in fact the Newton determinism in classical world does not hold and in classical mechanics there is fundamental and irreducible randomness.

Genomic Diversity and Clinical Variability in Pediatric Primary Cutaneous Anaplastic Large Cell Lymphoma: A Case Series

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Primary cutaneous anaplastic large cell lymphoma (pcALCL) is a rare pediatric CD30‐positive T‐cell lymphoproliferative disorder with an excellent prognosis, but its genomic drivers are poorly defined. We report three children with skin‐limited disease demonstrating striking molecular heterogeneity, including NPM::ALK, NUP214::FRK, and a novel ...

First-Principles Investigation of Diverse Properties of X₂CaTa₂O₇ (X = Li, Na, K, and Rb) Ruddlesden–Popper Compounds for Photovoltaic Applications

Crystals
For the first time, we explored the optical, electronic, mechanical, and structural properties of the Ruddlesden–Popper phase family member X2CaTa2O7 (X = Li, Na, K, and Rb) by using density functional theory (DFT) with the Perdew–Burke–Ernzerhof (PBE ...

Feasibility and Safety of Somato‐Cognitive Coordination Therapy for Cerebellar Ataxia Following Pediatric Brain Tumor Treatment

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Background Cerebellar ataxia after pediatric brain tumor treatment can cause persistent gait, balance, and speech impairment, yet no established rehabilitation strategy exists. Somato‐cognitive coordination therapy (SCCT) is a virtual reality–guided intervention designed to promote sensorimotor integration through visually constrained reaching
