The Silver Plasma was Produced by Employing an Nd-YAG Pulsed Laser (100 mJ,1064 nm,) on the Surface of Silver foil in the Presence of B = 0.75 T, which Analyzed the Significant Enhancement in the LIBS Sensitivity by Detecting the Essential and Toxic Elements (C, Ag, Al, Fe, Ca, Cr, Si, Mg, Na) in Silver Plasma. The Enhancement Factor is up to four-fold and Optical Emission Intensity, Plasma Parameters like Plasma Temperature (T<sub>e</sub>) and electron Number Density (n<sub>e</sub>) were Enhanced in the Presence of a Magnetic Field (B). The Signal Enhancement in Silver Plasma was Ascribed to Magnetic Confinement and an Increase in Recombination rate after Relaxing the Plasma. Moreover, the Value of Thermal beta is Estimated Analytically (βt < 1) in this Study, which Confirms the Validity of Magnetic Confinement in all Samples. The Elemental Composition was Determined by the Calibration-Free LIBS (CF-LIBS) Approach with Zero Fields and B-field.

The proposed model incorporates the role of adaptive immunity in limiting viral pathogen spread, including humoral and cellular immune responses. This paper focuses on describing the long memory effect using the Caputo derivative. This study begins with the investigation of the well-posedness of our mathematical model concerning demonstrating the existence, positivity and boundedness of solutions. Then, it moves to introduce all the problem’s steady states, which are determined by specific reproduction numbers. Subsequently, the work proceeds to demonstrate the global stability of the five equilibria points. To evaluate the theoretical findings of global stability, we employ a numerical technique based on the fundamental theorem of fractional calculus, in addition to utilizing a three-step Lagrange polynomial interpolation method. Numerical simulations have shown the effect of drug therapies on the dynamical behavior of the fractional-order system.</p></div>","PeriodicalId":600,"journal":{"name":"Iranian Journal of Science and Technology, Transactions A: Science","volume":"49 3","pages":"847 - 869"},"PeriodicalIF":1.4,"publicationDate":"2025-02-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143938263","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"综合性期刊","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Targets are proteins in the human cells. The drug compounds interact with the target, which helps to cure diseases of human beings. One of the most important areas of research in the field of drugs discovery is drug–target interaction (Öztürk et al. in Bioinformatics 34(17):i821–i829, 2018). It identifies interactions between proteins and targets in the human body and the chemical compounds in drugs. Several resources were wasted in terms of the cost and the time spent on research laboratory experiments to find the drug discovery. It is essential for drug discovery to make accurate predictions of drug–target interactions (DTI). A recent study found that deep learning (DL) models perform well at predicting DTI. Here now introduce Deep Purpose, an extensive and user-friendly DL library for DTI prediction. Drug repurposing is a technique for expanding or improving the use of a current drug or creating new uses for current drugs. In this case, gave pre-existing medications for the SARS CoV2 3CL protease repurposing method. The results were the ratings for each drug’s binding affinity to the SARS CoV2 3CL protease inhibitor. Building a machine learning regression model using the SARS CoV2 3CL protease inhibitor’s ChEMBL bioactivity data is also possible.
