H-Kernels in Unions of H-Colored Quasi-Transitive Digraphs
Discussiones Mathematicae Graph Theory, 2021 Let H be a digraph (possibly with loops) and D a digraph without loops whose arcs are colored with the vertices of H (D is said to be an H-colored digraph). For an arc (x, y) of D, its color is denoted by c(x, y). A directed path W = (v0, . .

H-kernels by walks in H-colored digraphs and the color-class digraph
AKCE International Journal of Graphs and Combinatorics, 2016 Let H be a digraph possibly with loops and D a finite digraph without loops whose arcs are colored with the vertices of H (D is an H-colored digraph). V(D) and A(D) will denote the sets of vertices and arcs of D respectively.

H-KPP: Hypervisor-Assisted Kernel Patch Protection
Applied Sciences, 2022 We present H-KPP, hypervisor-based protection for kernel code and data structures. H-KPP prevents the execution of unauthorized code in kernel mode. In addition, H-KPP protects certain object fields from malicious modifications.

Effect of soaking conditions on physico-chemical characteristics of Indian walnuts
European Journal of Horticultural Science, 2023 Summary In South Asia, particularly in India, it is a common practice to soak the walnuts in water for about 12–20 h prior to cracking so as to get good recovery of kernel halves.

Extensions of Richardson’s theorem for infinite digraphs and (𝒜, ℬ)-kernels
AKCE International Journal of Graphs and Combinatorics, 2020 Let D be a digraph and and two subsets of where = {P: P is a non trivial finite path in D}. A subset N of V(D) is said to be an ()-kernel of D if: (1) for every {u,v} N there exists no uv-path P such that P (N is -independent), (2) for every vertex x in ...

A new reverse half-discrete Mulholland-type inequality with a nonhomogeneous kernel
Journal of Inequalities and Applications, 2023 In this paper, a new reverse half-discrete Mulholland-type inequality with the nonhomogeneous kernel of the form h ( v ( x ) ln n ) $h(v(x)\ln n)$ and the best possible constant factor is obtained by using the weight functions and the technique of real ...
