Sub-Alfvénic Turbulence: Magnetic-to-kinetic Energy Ratio, Modification of Weak Cascade, and Implications for Magnetic Field Strength Measurements
Published 2024-01-01“…Since the assumption of magnetic and kinetic energy equipartition is at the core of the Davis–Chandrasekhar–Fermi (DCF) approach to measuring magnetic field strength in sub-Alfvénic turbulence, we conclude that the DCF technique is not universally applicable. In particular, we suggest that the dynamical excitation of long azimuthal wavelength modes in the galactic disk may compromise the use of the DCF technique. …”

(Sr1-xCax)2SnO4 microwave dielectric ceramics with Ruddlesden-Popper structure (x = 0–0.06) for microwave application
Published 2025-07-01“…Additionally, the temperature coefficient of resonant frequency (τf) decreased with increasing Ca content, reaching a minimum of 1.45 ppm/°C at x = 0.02, suggesting enhanced thermal stability attributed to modified bond dynamics and increased lattice rigidity. The optimal composition (x = 0.02) demonstrated excellent dielectric performance, with εᵣ = 33, Q×f = 32,517 GHz, and near-zero (τf), making it a promising candidate for high-performance microwave dielectric applications in next-generation telecommunication systems.…”

A Refined Model for Ablation Through Cavitation Bubbles with Ultrashort Pulse Lasers
Published 2024-11-01“…The cross-over points from which the photodisruption model dominates tend to be reduced for larger E<sub>Th</sub>. A new universally applicable model for plasma-induced ablation has been hypothesized that considers the cavitation bubble volume and potentially better explains the bubble dynamics during intrastromal processes. (4) Conclusions: This theoretical exploration and the comparison of the outcomes to empirical data substantiate that inadvertently using the photodisruption model to explain the cavitation bubble dynamics for the entire spectrum of pulse energies and laser systems might provide erroneous estimates of cavitation bubble sizes. …”
