Assessment of the authenticity of fruit spirits by gas chromatography and stable isotope ratio analyses

open access: yesCzech Journal of Food Sciences, 2008
The gas chromatographic (GC) determination of volatile constituents and the determination of 13C/12C isotope ratios by isotope ratio mass spectrometry - IRMS analysis as well as SNIF-NMR analysis of (D/H)I and (D/H)II ratios in ethanol are prospective ...

Children’s reasoning about violations of authenticity [PDF]

open access: yes, 2013
textWhen do children begin to realize that the authenticity of an object is not inherent to an object itself, but instead depends on the information one has about the object in question?

Sustainable Materials Design With Multi‐Modal Artificial Intelligence

open access: yesAdvanced Science, EarlyView.
Critical mineral scarcity, high embodied carbon, and persistent pollution from materials processing intensify the need for sustainable materials design. This review frames the problem as multi‐objective optimization under heterogeneous, high‐dimensional evidence and highlights multi‐modal AI as an enabling pathway.

Physics‐Constrained Constitutive Learning of Rate‐Limiting Timescales for Efficient Hydrogen‐Based Direct Reduction for Green Steel Making

open access: yesAdvanced Science, EarlyView.
A conversion‐resolved constitutive framework is developed for the hydrogen‐based direct reduction of iron oxide pellets. Effective reaction and transport timescales are inferred directly from measured trajectories and mapped against operating conditions, pellet architecture, and composition. The analysis reveals how late‐stage transport control emerges

Voice attribution, verification gaps, and political synthetic audio: an evidence audit of the Starmer and Khan fake-audio incidents in the United Kingdom

open access: yesCogent Arts & Humanities
Generative artificial intelligence has made it easier to clone, edit, and recontextualize the voices of political figures, placing new pressure on the evidentiary practices through which political communication is verified.

Automating Chemical Reasoning in High‐Throughput Phase Identification With a Probabilistic, LLM‐Guided Framework

open access: yesAdvanced Science, EarlyView.
Autonomous laboratories can now synthesize materials faster than experts can interpret the resulting diffraction data. A probabilistic framework combines refinement‐fit metrics with large language model‐derived chemical reasoning to rank competing phase interpretations and flag those unsuitable for autonomous use.

Online integrity and authentication checking for Quran electronic versions

open access: yesApplied Computing and Informatics, 2017
AbstractThe ability to control data and information through the Internet can be challenging. Preliminary analysis showed that some tampering and forgery may occur to some words of the Quran in the electronic versions that span the Internet. Such small modifications may not be noticed by public audience.

Experience‐Dependent Reorganization of Hippocampal CA3 Neuronal Ensembles Associates With Memory Generalization

open access: yesAdvanced Science, EarlyView.
Mice can transfer the learned rule of spatial working memory to guide similar but novel tasks. Hippocampal CA3 populational activity dynamically reorganize during memory generalization, shifting from task‐specific to generalized coding over testing days. Sparse yet redundant neural representations of CA3 enable rule transfer and cognitive map formation,

Perceived authenticity and museum visitors' behavior: a case of South Tirol's museum of archeology in Bolzano [PDF]

open access: yes
In this study we analyze perception of authenticity by visitors of South Tyrol's museum of archeology, best known as Otzi museum, in the Autonomous Province of Bolzano (Italy).

Pasta, a Versatile Transcriptomic Clock, Maps the Chemical and Genetic Determinants of Aging and Rejuvenation

open access: yesAdvanced Science, EarlyView.
Pasta is a transcriptomic aging clock built on an age‐shift learning framework and trained on 17 000 samples across 21 datasets. It accurately predicts relative biological age across tissues, platforms, and species, captures stemness‐to‐senescence transitions, and identifies age‐modulatory perturbations.
