Machine Learning‐Based Correction of Reanalysis Surface Radiation Fluxes Using Ground‐Measured Data in the Southern Brazilian Pampa Biome

open access: yesInternational Journal of Climatology, EarlyView.
This study demonstrates that ERA5 provides more accurate surface radiation flux estimates than MERRA2 across the Southern Brazilian Pampa. Machine learning models, particularly Random Forest, further improved the precision of reanalysis data for climate applications.

Detection of Acoustic Phonons in Carbon by Raman Spectroscopy

open access: yesJournal 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.

Parallel Multi‐Target Detection for Quantum LiDAR

open access: yesLaser &Photonics Reviews, EarlyView.
Parallel multi‐target detection is achieved in quantum LiDAR with a single‐pixel quantum readout. Direction and distance information are extracted together, allowing multiple objects to be distinguished under noisy low‐light conditions and pointing to a new strategy for scan‐free quantum remote sensing.

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

open access: yesMass 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).

Analysis of Carbohydrates and Glycoconjugates by Matrix‐Assisted Laser Desorption/Ionization Mass Spectrometry: An Update for 2023–2024

open access: yesMass Spectrometry Reviews, EarlyView.
ABSTRACT The use of MALDI mass spectrometry for the analysis of carbohydrates and glycoconjugates is a well‐established technique and this comprehensive review is the twelfth update of the original article published in 1999 and brings coverage of the literature to the end of 2024.

Computational Analysis of the Vibrational Response of Lunar Regolith Made of Nonspherical Grains

open access: yesInternational Journal for Numerical and Analytical Methods in Geomechanics, EarlyView.
ABSTRACT Vibration‐based systems have shown that appropriately oriented and tuned mechanical oscillations can disrupt regolith interlocking and promote flow. Building on this evidence, the present study investigates vibration‐controlled granular discharge as a potential ISRU (In Situ Resource Utilization) strategy, with the aim of supporting ...
