1. Francesco A. Fabozzi Managing Editor The selection of models for an ensemble is problem dependent. In the first article, “Ensemble Meta-Labeling,” Dennis Thumm, Paolo Barucca, and Jacques Francois Joubert develop a framework choosing model architectures meta-labeling

With the fast development of networks, one has to focus on security information running in real networks. A technology that might be able resist attacks equipped with AI techniques and quantum computers is so-called topological graphic password coding. In order further study coding, we use multiple constraints graph colorings labelings propose 6C-labeling, 6C-complementary labeling, its recipro...

Background: Definite data regarding the incidence and distribution of renal tumours in eastern India is not known. For better management, as it is essential to identify patients with poor prognosis, prognostic factors like stage, nuclear grade and their relationship to molecular markers are also unclear in this region. The purpose of our study was to assess the spectrum of adu...

Let D(p, q) be a digraph. A function f: V → {1, 2, ..., n} is said to neighborhood prime labeling of D if it both in and out degree labeling. In this paper, we introduce the concept digraphs also investigate existence some digraphs.
