Diet of bird‐like troodontid dinosaurs: synthesis of a contentious clade
Biological Reviews, EarlyView.ABSTRACT Troodontidae is a clade of small‐to medium‐sized maniraptoran theropods that mainly lived in Laurasia (modern Asia, North America and Europe) during the Jurassic and Cretaceous periods and are believed to have had a variety of diets. The uniqueness of troodontid teeth suggests that they diverged from the typical flesh‐based diet of non‐avian ...

Versatile Palladium‐Catalyzed C‐H Arylation of Fluoroarenes with 2‐Chloropyridine Derivatives
Chemistry – A European Journal, EarlyView.Direct C─H arylation of fluoroarenes with 2‐chloropyridines is enabled by a simple Pd/SPhos system in isopropyl acetate. The method uses inexpensive reactants and shows broad scope and high yields. DFT computations explain reactivity and selectivity.

The $t$-successive associated Stirling numbers, $t$-Fibonacci--Stirling numbers, and unimodality
TURKISH JOURNAL OF MATHEMATICS, 2017 Summary: Using a combinatorial approach, we introduce the \(t\)-successive associated Stirling numbers, and we give the recurrence relation and the generating function. We also establish the unimodality of sequence \(\left\{\frac{n-2k}{k}\right\}_{k}\) lying over a ray of the Stirling triangle of the second kind. Some combinatorial identities are given.

Ecography, EarlyView.Correlative species distribution models (SDMs) are quantitative tools in biogeography and macroecology. Building upon the ecological niche concept, they correlate environmental covariates to species presence to model habitat suitability and predict species distributions.

European Policy Analysis, EarlyView.ABSTRACT In response to renewed interest in analytical tools that address complex policy problems and move beyond linear‐rational approaches in policy appraisal, Social Multi‐Criteria Evaluation (SMCE) integrates participatory approaches with multi‐criteria analysis (MCA), thereby incorporating specialised knowledge and diverse social values and ...

BAXTER ALGEBRAS, STIRLING NUMBERS AND PARTITIONS [PDF]
Journal of Algebra and Its Applications, 2005 Recent developments of Baxter algebras have led to applications to combinatorics, number theory and mathematical physics. We relate Baxter algebras to Stirling numbers of the first and the second kinds, partitions and multinomial coefficients. This allows us to apply congruences from number theory to obtain congruences in Baxter algebras.

Energy Science &Engineering, EarlyView.Approximately 64% of the population in sub‐Saharan Africa lacks access to electricity, despite the region's high solar potential, making concentrated solar power a promising solution for decentralized and sustainable energy supply. This study presents the design, construction, and testing of a parabolic solar concentrator with two focal‐point receivers
