This paper explores the feasibility of Tierra-based OBC that evolves programs through a bit inversion caused by Single-Event Upset. In particular, Tierra-based OBC is applied to the evolution of the PIC assembly programs. Additionally, this paper proposes a new method that can reliably recover the broken program to the correct one. Intensive experiments reveal that (1) Tierra-based OBC cannot o...

This paper describes a new technique for improving the performance of multistage parallel interference cancellation (PIC) multiuser detection. The focus of the paper is on the hard-decision multistage PIC detector due to the fact that it possesses two desirable properties: (a) very low computational complexity in binary communication systems and (b) the optimum (joint maximum likelihood) bit es...

This paper presents the PIC matrices, a computationally efficient subclass of link matrices that may be considered for the interpretation of query operators in the INQUERY inference network. The PIC class of matrices is formally defined; a algorithm, PIC-EVAL, is presented for the evaluation of members of this class; and a proof of the correctness of the algorithm is given. A further specializa...

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.
