Decision Theory and Proof Standards for Future Crimes: Possible Uses and Open Questions

Behavioral Sciences &the Law, EarlyView.
ABSTRACT What should be the proof standard for applying preventive criminal sanctions based on an establishment of risk of reoffending? This is an open question in legal systems around the world. Various authors suggest that we can answer it by using decision theory. This approach conceptualises the proof standard as a probabilistic threshold. A person

Constructing Enzyme‐Inspired Multisite Synergistic Catalyst for Promoting CO2 Electroreduction to Ethylene at pH Universal Condition

Carbon Energy, EarlyView.
A rational synthesis strategy was developed to construct enzyme‐inspired Cu‐AM catalysts with well‐defined multisite architectures. This catalytic system enables highly selective electrochemical CO2 reduction to C2H4 under pH‐universal conditions, delivering exceptional Faradaic efficiencies across acidic, neutral, and alkaline electrolytes.

From Charge‐Transfer Adducts to (Tri)Halide‐Templated Supramolecular Cages: Covalent vs Ionic Products in the Reactions of Pyridin‐4‐ylthio‐Substituted Tetrathiafulvalene With Dihalogens and Interhalogens

Chemistry – A European Journal, EarlyView.
The reactions between tetra(pyridin‐4‐ylthio)tetrathiafulvalene and Br2/I2/ICl/IBr led to a variety of products, including a rare example of neutral 1:4 CT adduct and ionic products showing supramolecular cage motifs at (tri)halide templates. The nature of the reaction products was elucidated based on XRD analysis, Raman spectroscopy and QTAIM, NCI ...

Synthesis, Structures, and Properties of Cyclopenta‐Fused Anthra[1,2‐a]anthracene Derivatives as New Polycyclic Aromatic Compounds

Chemistry – A European Journal, EarlyView.
Three new polycyclic aromatic compounds consisting of one or two five‐membered rings were synthesized by Scholl reaction or Pd‐catalyzed cyclization from fused anthracene derivatives. X‐ray analysis and DFT calculations revealed that these compounds have slightly twisted or curved structures.

Fatty liver disease is not associated with increased mortality in the elderly: A prospective cohort study

Hepatology, EarlyView., 2022
Graphical abstract summarizing the study design, main results and key findings Abstract Background and Aims Fatty liver disease (FLD) has been associated with excess mortality. Screening for hepatic steatosis (HS) in patients with metabolic dysfunction is therefore recommended by several guidelines, despite a paucity of evidence on the clinical ...
