Decoding temporal miRNA signatures of semen under in vitro exposure for forensic time since deposition estimation using machine learning‐driven modeling

open access: yesInterdisciplinary Medicine, EarlyView.
This study develops a novel miRNA‐based framework for estimating the time since deposition of semen stains, combining small RNA sequencing with machine learning. Time‐dependent miRNA modules were identified using Mfuzz clustering and WGCNA, followed by a multi‐stage feature selection pipeline that reduced 261 candidate miRNAs to a minimal 7‐miRNA panel.

Psychopathy traits and their link to emotion recognition impairments in conduct disorder

open access: yesJCPP Advances, EarlyView.
Abstract Background Neurocognitive models suggest that callous‐unemotional (CU) traits in youths with conduct disorder (CD) are linked to emotion recognition impairments, particularly in identifying distress emotions like fear and sadness. However, CD may be accompanied by grandiose‐manipulative (GM) and/or impulsive‐irresponsible (II) traits in ...

Modular and Automated Workflow for Streamlined Raman Signal Analysis

open access: yesJournal of Raman Spectroscopy, EarlyView.
This study presents an automated workflow for preprocessing and analyzing Raman spectroscopy data, addressing key challenges such as noise suppression, baseline correction, and peak fitting using Voigt profiles. The method is validated on both synthetic and experimental spectra, demonstrating improved spectral fidelity and peak detection for biomedical

Unveiling the Crystal Structure of Sanidine: A Polarized Raman and Ab Initio Simulation Exploration

open access: yesJournal of Raman Spectroscopy, EarlyView.
This study combines polarized Raman spectroscopy and ab initio calculations to assign theoretical vibrational modes to observed spectra. Polarized Raman spectra were collected in six geometries (40–1200 cm−1). Theoretical predictions via DFT show good agreement with experiments, though some discrepancies point to influences like trace elements and ...

Experimental and Computational Raman and SERS Study of Acid Blue 113

open access: yesJournal of Raman Spectroscopy, EarlyView.
The vibrational features of AB‐113 were investigated through experimental and theoretical analyses. SERS spectra showed enhanced responses under resonant excitation, especially at 532 and 632.8 nm, enabling identification limits as low as 1.0 × 10−8 mol L−1.
