q-Genocchi Numbers and Polynomials Associated with q-Genocchi-Type l-Functions

Advances in Difference Equations, 2008
The main purpose of this paper is to study on generating functions of the q-Genocchi numbers and polynomials. We prove new relation for the generalized q-Genocchi numbers which is related to the q-Genocchi numbers and q-Bernoulli numbers.

Newton series expansion of bosonic operator functions

SciPost Physics, 2021
We show how series expansions of functions of bosonic number operators are naturally derived from finite-difference calculus. The scheme employs Newton series rather than Taylor series known from differential calculus, and also works in cases where the ...

Fractional Moment Theory for Anomalous Transport: A Unified Framework for Lévy Flights, Fractals, and Complex Dynamical Systems

Mathematical Methods in the Applied Sciences, EarlyView.
ABSTRACT We develop a unified mathematical framework extending classical moment theory from discrete integer orders to a continuous spectrum of real orders f>0$$ f>0 $$, providing a systematic statistical characterization of complex systems exhibiting power‐law behavior.

Exploring Role and Experience Factors on a Virtual, ECHO‐Based School Mental Health Professional Development Program: An Implementation Science Perspective

Psychology in the Schools, EarlyView.
ABSTRACT In‐service training for school staff, generally referred to as professional development (PD), may bolster a school's capacity for implementing school mental health (SMH) services. However, not all PD results in knowledge or behavior change. In one model of PD, Project Extension for Community Healthcare Outcomes (ECHO), participants collaborate

Four-loop anomalous dimension of flavor non-singlet quark operator of twist two and Lorentz spin N for general gauge group: Transcendental part

Nuclear Physics B
Both for quark flavor asymmetry and valence, we consider the anomalous dimension of the non-singlet twist-two quark operator of arbitrary Lorentz spin N at four loops in SU(nc) color gauge theory and present its term proportional to ζ(3) in closed form ...

Valuing Options in Heston's Stochastic Volatility Model: Another Analytical Approach

Journal of Applied Mathematics, 2011
We are concerned with the valuation of European options in the Heston stochastic volatility model with correlation. Based on Mellin transforms, we present new solutions for the price of European options and hedging parameters.

Evaluating the protection status and exposure to warming of Caribbean reefs with high functional potential

Conservation Biology, EarlyView.
Abstract Over the past decades, climate change has emerged as a major threat to global biodiversity, negatively affecting the integrity and functioning of ecosystems and the benefits they provide to people. To mitigate these impacts, it is essential to identify climate refugia that support the persistence of the structure and function of reef ...

GKZ hypergeometric systems of the four-loop vacuum Feynman integrals

Journal of High Energy Physics
Basing on Mellin-Barnes representations and Miller’s transformation, we present the Gel’fand-Kapranov-Zelevinsky (GKZ) hypergeometric systems of 4-loop vacuum Feynman integrals with arbitrary masses. Through the GKZ hypergeometric systems, the analytical

A new Riemann–Liouville type fractional derivative operator and its application in generating functions

Advances in Difference Equations, 2018
Here, the concept of a new and interesting Riemann–Liouville type fractional derivative operator is exploited. Treatment of a fractional derivative operator has been made associated with the extended Appell hypergeometric functions of two variables and ...
