Detection of Acoustic Phonons in Carbon by Raman Spectroscopy

Journal of Raman Spectroscopy, EarlyView.
Acoustic phonons in graphite and diamond are detected by Raman spectroscopy through disorder‐induced relaxation of selection rules. Comparison with calculated phonon densities of states enables assignment of the observed Raman features to acoustic phonon branches.

High‐Fidelity Synthetic Raman Spectra Generation for Sinter Basicity Prediction Using β$$ \beta $$‐Variational Autoencoders

Journal of Raman Spectroscopy, EarlyView.
A β$$ \beta $$‐variational autoencoder with β$$ \beta $$ = 0.1 generates high‐fidelity synthetic Raman spectra of industrial sinter with a 16‐fold improvement in spectral fidelity over SMOTE‐based augmentation (KL divergence: 0.0075 vs. 0.121), enabling reliable basicity prediction (R2 = 0.83) from limited labeled datasets.

Analytical Approaches to Address Challenges in the Analysis of Cannabinoids in Vascular Matrices Using Mass Spectrometry

Mass Spectrometry Reviews, EarlyView.
ABSTRACT Phytocannabinoids are bioactive metabolites derived from the Cannabis sativa plant. They have garnered attention due to their recreational uses and therapeutic potential. Although various analytical strategies have been employed for their analysis, mass spectrometry (MS) coupled to chromatographic separation is superior due to its sensitivity ...

Chemical Ionization Mass Spectrometry: Fundamental Principles, Diverse Applications, and the Latest Technological Frontiers

Mass Spectrometry Reviews, EarlyView.
ABSTRACT The review examines the evolution of chemical ionization mass spectrometry (CI‐MS), a technique developed in 1966 by Field and Munson. CI is a soft‐ionization method that produces more intense molecular ions with less fragmentation than electron ionization (EI).

Data‐Independent Acquisition Mass Spectrometry in Tumor Classification and Cancer Biomarker Research

Mass Spectrometry Reviews, EarlyView.
Abstract Cancer treatment is far from optimal also because current classification systems do not reflect the complex molecular status of the tumor and its phenotype in sufficient detail. To construct molecular tumor classifiers, omics tools provide complex molecular data reflecting many aspects from genotype to phenotype.

Forensic dental identification

Forensic Science International, 2010
Identification of deceased persons is the most common role of the forensic dentist. Forensic physical comparison of antemortem and postmortem dental data is used to establish that a found body and a missing person are one and the same to a high degree of certainty. An overview of this role is presented as a review of dental identification.

Use of Orthopantomographs in Forensic Identification

The American Journal of Forensic Medicine and Pathology, 1991
Radiographs of the head region were used for identification of 17 victims during an 11-year period in the Department of Forensic Medicine, University of Turku, Finland. Examinations resulted in positive identification of 10 victims. Proof of identity of four people was based on exclusion identifications.

Forensic identification of urine samples

International Journal of Legal Medicine, 1992
VNTR polymorphisms were investigated for the possible individualisation of human urine samples with reference to doping cases in sport. Investigations were carried out with the RFLP single locus system YNH24/Hinf I and the PCR-VNTR systems Apo B and COL2A1 (AMPFLPs) as well as SE 33 and TC 11 (STRs). Urine samples were tested using 3 different volumes (
