A Graph-Based Method for Molecular Spectral Line Identification

open access: yesIntelligent Computing
To address the high computational cost associated with molecular identification in spectral lines, we propose a graph-based feature learning framework to determine the molecular composition of spectral lines that incorporates rule-driven and node-level ...

Spectral Line Identification in Photoionized Silicon Plasma Emission.

open access: yesProposed for presentation at the APS DPP 2020 held November 9-13, 2020 in Albuquerque, NM., 2020
Photoionized silicon plasma experiments were performed using the Z machine at Sandia National Laboratories. A spectrometer with high spectral resolution (λ/δλ~9200) was conceived to record emission from the expanding plasma. The data resolution is unprecedented for plasma emission and include detections of many previously unobserved spectral lines. The

Building an ensemble learning model for gastric cancer cell line classification via rapid raman spectroscopy

open access: yesComputational and Structural Biotechnology Journal, 2023
Cell misuse and cross-contamination can affect the accuracy of cell research results and result in wasted time, manpower and material resources. Thus, cell line identification is important and necessary.

Critically Evaluated Atomic Data for the Au iv Spectrum

open access: yesThe Astrophysical Journal Supplement Series, 2023
A spectral investigation of triply ionized gold (Au iv ) has been carried out in the wavelength region of 500–2106 Å. The gold spectra were photographed at the National Institute of Standards and Technology, USA, on a 10.7 m normal incidence vacuum ...

Saliva as a first-line diagnostic tool: A spectral challenge for identification of cancer biomarkers [PDF]

open access: yesJournal of Molecular Liquids, 2020
Abstract The paper concentrates on the role of saliva in the early diagnosis of salivary gland tumor. Due to the still not fully understood etiology of head and neck cancer, the fundamental objective of this study is to find tumor markers of salivary gland tumor progression.
