Carbon Performance, Climate Governance, and Equity Risk
International Journal of Finance &Economics, EarlyView.ABSTRACT This paper examines the relationship between carbon performance, climate governance, and equity risk. Using a sample of companies listed in the S&P500 index for the period 2009–2023, our results show that better carbon performance reduces equity risk, indicating that proactive carbon management reduces uncertainty and is beneficial to firms ...

Catalan Bounds for Symmetric Strength‐Two Orthogonal Arrays
Journal of Combinatorial Designs, EarlyView.ABSTRACT A Hamming shell construction is a two‐level array obtained by taking every binary vector of a given Hamming weight a prescribed number of times, for each weight in turn. Such arrays are invariant under all permutations of the factors, and they are strength‐two orthogonal arrays exactly when the multiplicities satisfy three linear constraints ...

Density Conditions for k $k$ Vertex‐Disjoint Triangles in Tripartite Graphs
Journal of Graph Theory, EarlyView.ABSTRACT Let n , k $n,k$ be positive integers such that n ≥ k $n\ge k$ and G $G$ be a tripartite graph with parts A , B , C $A,B,C$ such that ∣ A ∣ = ∣ B ∣ = ∣ C ∣ = n $| A| =| B| =| C| =n$. Denote the edge densities of G [ A , B ] , G [ A , C ] $G[A,B],G[A,C]$ and G [ B , C ] $G[B,C]$ by α , β $\alpha ,\beta $ and γ $\gamma $, respectively.

Saturated Partial Embeddings of Planar Graphs
Journal of Graph Theory, EarlyView.ABSTRACT In this work, we study how far one can deviate from optimal behavior when embedding a planar graph. For a planar graph G $G$, we say that a plane subgraph H ⊆ G $H\subseteq G$ is a plane‐saturated subgraph if adding any edge (possibly with new vertices) to H $H$ would either violate planarity or make the resulting graph no longer a subgraph of

Journal of the Science of Food and Agriculture, EarlyView.Abstract BACKGROUND This study investigated cultivar‐dependent variation in the phytochemical composition of lettuce (Lactuca sativa) using liquid chromatography–tandem mass spectrometry (LC–MS/MS) profiling and high‐performance liquid chromatography (HPLC) quantification, with a focus on enzyme inhibitory activity. RESULTS Significant differences were

International Journal of Chemical Kinetics, EarlyView.ABSTRACT The temperature dependence of the reaction rate coefficients (k) for the reactions of hydroxyl radical with three alkenes was measured by using laser‐induced fluorescence techniques in the temperature range of 298–750 K. The negative temperature dependence of k was observed for each reaction in the low‐pressure range.

Theory of Supercritical Coupling and Generalized Bound States in the Continuum
Laser &Photonics Reviews, EarlyView.We develop a general theory of supercritical coupling and generalized bound states in the continuum (gBICs), revealing how interference between radiative and absorptive channels enables quality factors beyond conventional material‐loss limits. The framework unifies non‐Hermitian mode coupling, causality‐driven reactive interactions, and interference ...
