Packing colorings of the corona product of the path Pn and the cycle Cn with an edge K₂
(Işık University Press, 2026-01-01)Given a graph G and a positive integer i, an i-packing in G is a subset X of V (G) such that the distance dG(u, v) between any two distinct vertices u, v ∈ X is greater than i. The packing chromatic number χρ(G) of a graph ... -
Moments of order statistics and k-record values arising from the Beta-Lomax distribution with application
(Işık University Press, 2026-01-01)The concept of k-record values plays a significant role in extreme value theory, which is essential for modeling rare events. In this paper, we focus on k- record values from the Beta-Lomax distribution(BLD), a flexible ... -
Approximations to Caputo fractional derivative with arbitrary kernels and uniform meshes

Generalized fractional heat equation in extended Colombeau algebras
(Işık University Press, 2026-01-01)In this paper, we use the Colombeau generalized algebra to prove the existence and uniqueness of the solution of fractional heat equation with singular potentials (i.e., singular distributions). The concept of a generalized ... -
On various algebraic structures in multidimensional fuzzy sets
(Işık University Press, 2026-01-01)One recent generalization of Zadeh’s fuzzy sets is the concept of multidimensional fuzzy sets. This work extends this concept further by introducing a generalized form of multidimensional fuzzy algebra. By focusing on ... -
Chemical hazards in propolis: evaluating the risks of pesticide and heavy metal contamination
(Işık University Press, 2025-12)Propolis is a complex biomaterial synthesized by honeybees (Apis mellifera) through the combination of plant resins, beeswax, and salivary gland enzymes. Historically employed for wound healing, infection prevention, and ... -
Electrophysiological methods in insect olfaction: a review of EAG, GC-EAG, SSR and GC-SSR approaches
(Işık University Press, 2025-12)Background: Insects rely on olfaction as a key sensory modality regulating reproduction, foraging, host location, and defense. Antennae function as highly sensitive chemosensory organs capable of detecting volatile organic ... -
