Euler and the multiplication formula for the Gamma Function
Euleriana, 2021 We show that an apparently overlooked result of Euler from \cite{E421} is essentially equivalent to the general multiplication formula for the $ $-function that was proven by Gauss in \cite{Ga28}.

Dense Coconut Oil‐in‐Water (CO‐Water) Emulsification via a Vortex‐Based Cavitation Device
Chemical Engineering &Technology, EarlyView.This study investigates the emulsification of coconut oil‐in‐water (CO‐water) emulsions using a vortex‐based hydrodynamic cavitation (HC) device. The present study explores the influence of dispersed phase on produced O/W emulsions without changing the surfactant type and concentration.

Chemistry – A European Journal, EarlyView.This study explores gadolinium metal‐organic frameworks (Gd‐MOFs) as dual‐functional platforms for anticancer drug delivery and radiosensitization. Synthesized using terephthalic acid and gadolinium (III) chloride hexahydrate, Gd‐MOFs were loaded with methotrexate (MTX) and characterized via fourier transform infrared spectroscopy (FTIR ...

Susceptible‐infected‐recovered model with stochastic transmission
Canadian Journal of Statistics, EarlyView.Abstract The susceptible‐infected‐recovered (SIR) model is the cornerstone of epidemiological models. However, this specification depends on two parameters only, which results in its lack of flexibility and explains its difficulty to replicate the volatile reproduction numbers observed in practice.

Deep Q‐learning: A robust control approach
International Journal of Robust and Nonlinear Control, Volume 33, Issue 1, Page 526-544, 10 January 2023., 2023 Abstract This work aims at constructing a bridge between robust control theory and reinforcement learning. Although, reinforcement learning has shown admirable results in complex control tasks, the agent's learning behavior is opaque. Meanwhile, system theory has several tools for analyzing and controlling dynamical systems.

Some Evaluation of Quadratic Euler Sums [PDF]
arXiv, 2017 In this paper, we obtain some formulas for double nonlinear Euler sums involving harmonic numbers and alternating harmonic numbers. By using these formulas, we give new closed form sums of several quadratic Euler series through Riemann zeta values, polylogarithm functions and linear sums. Furthermore, some relationships between Euler sums and integrals

Experimental Study on Instability Mechanism of Red Shale Roadway Under Dynamic Disturbance
Energy Science &Engineering, EarlyView.ABSTRACT To delve into the instability mechanism of the surrounding rock in red shale roadways, a bespoke device was chosen to fabricate a physical model, and a similar experiment was conducted with a blasting‐induced disturbance. A meticulous examination was performed on the evolution of surface fractures and the macroscopic failure patterns of the ...

Energy Science &Engineering, EarlyView.ABSTRACT To reduce the peak vibration velocity (PPV) of subgrade bench blasting vibration, the control variable method was used to analyze the blasting effect of different charging methods. Initially, the control variable method was used to evaluate the blasting performance of different charge structures.
