Selective six spectrophotometric methods for determination of remdesivir and moxifloxacin hydrochloride for COVID-19 treatment with overlapping spectra: a comprehensive evaluation... by Eman A. Madbouly, Abdalla A. El-Shanawani, Sobhy M. El-Adl, Ahmed S. Abdelkhalek

“…Because of the considerable spectral overlap, six mathematical spectrophotometric approaches were applied, including ratio derivative, ratio difference, mean centering of ratio spectra, area under the curve, Q-analysis, and bivariate calibration, to allow accurate interference-free determination without preliminary separation. The proposed methods were validated as per ICH guidelines, demonstrating excellent linearity over the concentration ranges of 1–15 µg/mL for RDV and 1–10 µg/mL for MFX, with correlation coefficients exceeding 0.999. …”

Improved RFID anti-collision algorithm based on ALOHA Abstract：In order to solve the problem of low efficiency of electronic tag identification in RFID system，a new ALOHA anti-collision algorithm was presented.In this algorithm，the coefficients of the tag estimation were automatically changed by using the dynamic adjustment method，which made the number of tag estimation could be dynamic changed with the number of identified tags，then the number of tags to be identified was estimated.And for the frame length adjustment，it could be determined by the relationship between the length of the frame and the tag number according to the estimated number of tags.With the tool of MATLAB，the results show that the proposed algorithm can significantly improve the throughput and stability of the system. by Yong WANG, Ting LI

ON IDENTIFICATION OF CONCRETE PLASTICIZING ADDITIVES by P. I. Yukhnevskiy, G. T. Schirokij

“…However, due to the fact that it is not possible to judge number of functional groups in the product by  absorption band size but it is possible only to assess their availability so it is recommended to use other methods. As an additional characteristics it is proposed to determine magnitude of the dipole moment in a  plasticizer-additive molecule. …”
