We assess the quantitative accuracy of the particle-in-cell (PIC) approximation used in recent ab initio predictions of the thermodynamic properties of hexagonal-closepacked iron at the conditions of the Earth’s inner core. The assessment is made by comparing PIC predictions for a range of thermodynamic properties with the results of more exact calculations that avoid the PIC approximation. It ...

In a multi-rate DS-CDMA system with multiple modulation, modulation format is adjusted according to the data rate of each user while symbol duration is fixed for all users. In this paper, two types of multi-stage partial parallel interference cancellation (PIC) receivers are considered for multirate DS-CDMA system with multiple modulation: multi-stage PIC receiver with partial cancellation fact...

We assess the quantitative accuracy of the particle-in-cell (PIC) approximation used in recent ab initio predictions of the thermodynamic properties of hexagonal-close-packed (hcp) iron at the conditions of the Earth’s inner core. The assessment is made by comparing PIC predictions for a range of thermodynamic properties with the results of more exact calculations that avoid the PIC approximati...

Aims. The aim of our work is to analyze the light curves $\beta$ Pic recently observed by TESS in sectors 32, 33, and 34, searching for signatures exocomet transits. Methods. We process from MAST database, applying frequency analysis remove harmonic signals due star's pulsations use a simple 1-D model fit profiles found events. Results. recover events previously other authors 5 6 find five new ...

Complex cis-[PtI2(NH3)(pic)] (pic = 2-methylpyridine), an iodido analogue of picoplatin, released the N-donor pic ligand in solution and isomerized, which complicates its subsequent testing for cytotoxicity.
