Mass spectrum of elementary particles [PDF]

open access: yesE3S Web of Conferences, 2023
In this study, we discuss different methods for quantifying the mass of elementary particles. The Barut’s model approach gives us a more comprehensive understanding of elementary particles and their formation through magnetic interaction.

Single-Molecule Detection of Nucleic Acids via Liposome Signal Amplification in Mass Spectrometry

open access: yesSensors, 2022
A single-molecule detection method was developed for nucleic acids based on mass spectrometry counting single liposome particles. Before the appearance of symptoms, a negligible amount of nucleic acids and biomarkers for the clinical diagnosis of the ...

Dracorhodin targeting CMPK2 attenuates inflammation: A novel approach to sepsis therapy

open access: yesClinical and Translational Medicine, 2023
Background Despite all modern advances in medicine, an effective drug for treating sepsis has yet to be found. The discovery of CMPK2 spurred hopes for the treatment of sepsis. However, CMPK2‐untapped target inhibitors are still an enormous obstacle that

Methane Cluster Fragmentation by Fast Electron Impact

open access: yesAtoms, 2023
We investigate the fragmentation of the CH4 cluster by fast electron impact at stagnation pressures from 0.5 bar to 16 bar. By measuring the time of flight spectrum (TOF), two types of ions, including (CH4)n−1CH5+ and (CH4)n−2(C2Hm)+, are observed.

Target mass dependence of photoneutron spectrum for 16.6 MeV photons on medium-heavy mass targets [PDF]

open access: yesEPJ Web of Conferences, 2023
We measured neutron energy spectra for the photonuclear reactions of 16.6 MeV linearly polarized photons on Pb, Au, Sn, Cu, Fe and Ti. The spectra for each target show dependence on the target mass, as well as on the angle between the directions of ...
