Abstract We report on analysis of X-ray, optical, and radio observations the previously overlooked X-ray source 2CXO J174517.0–321356 located just 3.°2 away from Galactic center. Timing with XMM-Newton reveals periodic pulsations periods 1228 614 s, latter being tentatively considered fundamental. On other hand, an observation object NuSTAR a hard thermal-bremsstrahlung spectrum. Inspection arc...

Density Functional Theory has been utilized to investigate the electronic and structural characteristics of Aluminium phosphide (AlP). The exchange-correlation potential was calculated using Generalized Gradient Approximation. structural, vibrational features AlP diamondoids nanocrystals were investigated at PBE/6-31(d) level, which included polarization functions. Vibrational modes have optimi...

O artigo realiza um levantamento e apresenta uma análise crítica dos estudos de Peirce em egiptologia 1885 a 1904, como documentados principalmente nos MSS 1227, 1228, 1244 1294. São examinados os seus avanços língua escrita do Egito Faraônico, bem suas análises das realizações científicas antigos egípcios. Entre tópicos linguísticos foco estão pressupostos respeito da iconicidade hieroglífica,...

Manililla is a mango variety whose residues contain bioactive compounds such as polyphenols and flavonoids, with high added value. The use of environmentally friendly extraction technology would be great relevance; hence, this study aimed to evaluate the effect solvent relation, sonication time amplitude on ultrasound-assisted total in (peel, endocarp kernel) antioxidant activity. An experiment...

Abstract We report the discovery in TESS data and validation of HD 56414 b (a.k.a. TOI-1228 b), a Neptune-size ( R p = 3.71 ± 0.20 ? ) planet with 29 day orbital period transiting young (age 420 140 Myr) A-type star southern continuous-viewing zone. is one hottest stars T eff 8500 150 K) to host known sub-Jovian planet. lies on boundary hot Neptune desert radius–bolometric insolation flux space...

This article considers change-point testing and estimation for a sequence of high-dimensional data. In the case mean shift independent data, we propose new test which is based on U-statistic in Chen Qin (Ann. Statist. 38 (2010) 808–835) utilizes self-normalization principle (Shao J. R. Stat. Soc. Ser. B. Methodol. 72 343–366; Shao Zhang Amer. Assoc. 105 1228–1240). Our targets dense alternative...

Background: AChR antibodies (Abs) in Myasthnia Gravis (MG) are detected approximately 50% of ocular and 85% generalized MG by the current gold standard radioimmunoprecipitation assay (RIPA). Recently, fixed lived Cell-Based assays (L-CBA) developed. We clinically validated our in-house L-CBA detecting Ab suspected patients. Methods: Between January 2020 April 2022, we assayed 10167 sera for RIP...
