Stimulated Raman scattering (SRS) has been explored comprehensively in planar-geometry experiments at the National Ignition Facility conditions relevant to corona of inertial confinement fusion ignition-scale direct-drive targets. These measured electron temperatures 4 5 keV simulated density scale lengths Ln 400 700 μm, and laser intensities quarter-critical up 1.5 × 1015 W/cm2 have determined SRS thresholds scaling behavior for various beam geometries. Several mechanisms, including...
Oral squamous cell carcinoma (OSCC) is the most common type of oral cancer with alarmingly high morbidity. The cancer-associated fibroblasts (CAFs) play a pivotal role in tumor development, while their specific mechanisms OSCC remains largely unclear. Our object to explore CAFs-related biomarker OSCC. Single-cell RNA sequencing (ScRNA-seq) analysis was used pinpoint CAF clusters samples. Differentially expressed genes and Cox regression analyses were identify candidate genes, functions...
We have developed SpectaVla, a code that solves the multi-dimensional Vlasov–Maxwell equations using spectral method described in G. L. Delzanno [J. Comp. Phys. 301, 338 (2015)].

Laser-plasma instabilities under ignition conditions for direct-drive inertial confinement fusion are studied using two-dimensional particle-in-cell simulations with a combination of in-plane (PP) and out-of-the-plane (SP) lasers.
