Small, EarlyView.High‐pressure studies of the lead‐free hybrid organic–inorganic ferroelectric [N(C2H5)3CH3]FeCl4 demonstrate record low compressibility, establishing it as the least compressible molecular ferroelectric known. In situ diamond anvil cell experiments identify halide selection and inorganic sublattice tuning as key compressibility controls, advancing ...

Computing Topological Indices and Polynomials of the Rhenium Trioxide
Journal of Mathematics, 2022 In the study of mathematical chemistry and chemical graph theory, a topological index, also known as a connectivity index, is the arithmetical framework of a graph that specifies its topology and also graph invariant.

Allergy, EarlyView.In two large European cohorts, 589 reactions to non‐mandatory labelled plant‐based foods were identified with sunflower seed, pine nut, pea and lentil as the most frequent triggers. Reaction severity was not different between mandatory and non‐mandatory labelled allergenic foods. Their frequency and rising trends (e.g., fenugreek, pumpkin seed) support

Conservation Biology, EarlyView.Abstract Knowledge of species distributions is essential for informing policies on nature conservation and restoration. However, updating them on a regular basis and doing so in a harmonized manner at the international level is difficult. The European Bird Census Council integrated national monitoring data covering 5 years to update farmland bird ...

Computing Connection-Based Topological Indices of Sudoku Graphs
Journal of Mathematics, 2022 A topological index (TI) is a function that associates a numeric number to the under-study molecular graph. The first TI based on distance was presented by Wiener to find the boiling point of paraffins.

Croatica chemica acta, 2004 A novel variant of the Zagreb indices introduced in 1972, called the variable Zagreb indices, is presented. Their performance in the QSPR modeling of lower (C3-C8) alkane boiling points is compared with the original Zagreb indices and their modifications. The variable Zagreb indices produce better single-descriptor models and participate in better two-

Infrastructure expansion, tourism and electoral outcomes
Economica, EarlyView.Abstract This paper examines the electoral impact of economic growth through increased foreign tourism using data from Croatia. To identify causal effects, the paper applies an instrumental variable strategy, which uses variation in the ruggedness of the local terrain to estimate the network of least‐cost paths.

Zagreb Polynomials and redefined Zagreb indices of nanostar dendrimers [PDF]
Open Physics, 2019 Abstract Dendrimers are profoundly extended natural macromolecules with successive layers of branch units encompassing a central core. Topological indicess are numbers related with graph of a compound to allow quantitative structureactivity/property/lethality connections.

Journal of the European Academy of Dermatology and Venereology, EarlyView.This pan‐European study reveals high rates of addiction in patients with chronic skin diseases. Smoking, alcohol, drug use, gambling, and internet addiction were prevalent and associated with quality of life, demographics, and region. The findings support integrating addiction screening into dermatologic care to improve outcomes.
