Congruences for harmonic sums [PDF]
Notes on Number Theory and Discrete Mathematics, 2023 Zhao found a curious congruence modulo p on harmonic sums. Xia and Cai generalized his congruence to a supercongruence modulo p². In this paper, we improve the harmonic sums Hₚ(n)=Σ_{l₁+l₂+...+lₙ=p, l₁,l₂,...,lₙ>0} 1/l₁+l₂+...+lₙ to supercongruences ...

Ambidextrous Leadership and Employee Work Outcomes: A Paradox Theory Perspective
Frontiers in Psychology, 2020 Numerous studies have examined the influence of ambidextrous leadership on employee work outcomes, but few have explored the issue through the congruence or incongruence of two seemingly conflicting leadership styles.

THE LATTICE OF CONGRUENCES ON A TERNARY SEMIGROUP [PDF]
Journal of Algebraic Systems, 2018 In this paper we investigate some properties of congruences on ternary semigroups. We also define the notion of congruence on a ternary semigroup generated by a relation and we determine the method of obtaining a congruence on a ternary semigroup T from a

Robustness Analysis of Deep Learning-Based Lung Cancer Classification Using Explainable Methods
IEEE Access, 2022 Deep Learning (DL) based classification algorithms have been shown to achieve top results in clinical diagnosis, namely with lung cancer datasets. However, the complexity and opaqueness of the models together with the still scant training datasets call ...
