Important parameters for optimized metal nanoparticles-aided electromagnetic field (EMF) effect on cancer.

This paper presents a theoretical model analyzing parameters that may optimize metal nanoparticle-aided EMF photothermal therapy effects on cancer cells. The model suggests efficacy depends on both electric field enhancement and thermal (hyperthermia) contributions, influenced by nanoparticle absorption properties…

Dielectric aggregation kinetics of cells in a uniform AC electric field.

This study develops and tests a theoretical model of how HeLa cells aggregate when exposed to a uniform AC electric field. Model-derived aggregation times and predicted string-length growth rates matched numerical simulation, and experiments observed substantial clustering in the chamber. The work is framed as…

Three-dimensional dynamics of a particle with a finite energy of magnetic anisotropy in a rotating magnetic field.

This paper presents a theoretical model of a single ferromagnetic particle with finite coupling between its magnetic moment and particle body in a rotating magnetic field. It describes synchronous and asynchronous motion regimes, including planar motion at low frequencies and a precession regime at high frequencies,…

Frequency-dependent electrodeformation of giant phospholipid vesicles in AC electric field.

This paper presents a theoretical model of giant phospholipid vesicle deformation in an alternating-current electric field, based on minimizing membrane bending energy and electric-field energy. The model treats the membrane and surrounding aqueous media as leaky dielectrics and reports good quantitative agreement…

Anomalous magnetic field dependence of Y Ba(2)Cu(3)O(7 - δ): effect of orthorhombic distortion.

This paper presents a theoretical model to investigate the origin of a mixed symmetry pairing state in the high-Tc superconductor YBa2Cu3O7-δ under applied magnetic fields between Hc1 and Hc2. The authors report that the model’s results, and their stated agreement with relevant experimental data, suggest orthorhombic…
