Mixed Steiner Triple Systems With Shortest Length
Journal of Combinatorial Designs, Volume 34, Issue 12, Page 533-544, December 2026.ABSTRACT A mixed Steiner triple system is a 3‐GDD which is viewed as a code with minimum Hamming distance 3. These codes are the minimum weight codewords of a 1‐perfect code over a mixed alphabet, when the related codes exist, and provide the connection between 3‐GDDs and coding theory.

Graph Homomorphism Revisited for Graph Matching [PDF]
, 2010 In a variety of emerging applications one needs to decide whether a graph G matches another Gp, i.e., whether G has a topological structure similar to that of Gp. The traditional notions of graph homomorphism and isomorphism often fall short of capturing

Journal of Graph Theory, Volume 113, Issue 4, Page 553-570, December 2026.ABSTRACT In an effort to understand the complexity of the maximum independent set problem, Chvátal introduced t‐perfect graphs. While a full characterization of this class remains open, important progress has been made for claw‐free graphs [Bruhn and Stein, Math. Program. 2012] and P 5‐free graphs [Bruhn and Fuchs, SIAM J. Discrete Math. 2017]. We take

Chromatic Ramsey Numbers and Two‐Color Turán Densities
Journal of Graph Theory, Volume 113, Issue 4, Page 663-676, December 2026.ABSTRACT Given a graph G, its 2‐color Turán number ex ( 2 ) ( n , G ) is the maximum number of edges in an n‐vertex graph, such that the edges can be colored with two colors avoiding a monochromatic copy of G. Let π ( 2 ) ( G ) = lim n → ∞ ex ( 2 ) ( n , G ) / n 2 be the 2‐color Turán density of G.

Tree Independence Number III. Thetas, Prisms and Stars
Journal of Graph Theory, Volume 113, Issue 4, Page 619-633, December 2026.ABSTRACT We prove that for every t ∈ N there exists τ = τ ( t ) ∈ N such that every (theta, prism, K 1 , t)‐free graph has tree independence number at most τ (where we allow “prisms” to have one path of length zero).

Quantitative Biology, Volume 14, Issue 4, December 2026.Abstract Manual curation of gene–disease–phenotype relationships from the human genetics literature is a persistent bottleneck for maintaining its bioinformatics databases. Whereas large language models (LLMs) offer a promising alternative, there is currently no systematic benchmark that evaluates whether state‐of‐the‐art commercial LLMs can perform ...

The Political U: New Evidence on the Economic Costs of Hybrid Regimes
Economics &Politics, Volume 38, Issue 3, Page 747-769, November 2026.ABSTRACT Recent research establishes a positive causal effect from democracy to income, although this evidence relies mostly on binary regime classifications. We extend the identification framework of Acemoglu et al. (2019) to a classification that distinguishes democracies, autocracies, and hybrid regimes for about 170 countries over 1960–2024.

GDP and GDI Growth Accounting in the Open Economy: Multiplicative Fisher Decompositions
Review of International Economics, Volume 34, Issue 5, Page 1116-1131, November 2026.ABSTRACT While most national statistical agencies still use chained Laspeyres indices in their national accounts, the U.S. Bureau of Economic Analysis (BEA) and Statistics Canada have been at the forefront for the past two decades by using instead a superlative index—the Fisher index—when computing price and quantity indices for GDP and its components.
