Alternative Proof of Frullani's Theorem and Applications in Evaluating Frullani Integrals

PUP Journal of Science and Technology
This article provides an alternative proof for the Frullani integral formula using an approach different from the existing one. This alternative proof gave us a novel method for evaluating certain improper integrals of Frullani type.

Carrier-Based Double Integral Sliding-Mode Controller of Class-D Amplifier

IEEE Access, 2019
This paper presents a carrier-based double integral sliding-mode (CBDISM) controller for a SiC class-D amplifier to compensate the $Q$ -factor and ensure a flatter frequency response.

Calculation and Experiment of Stray Inductance of PCB Double-Pulse Test Circuit Based on Three-Dimensional Simulation

IEEE Access, 2022
In high-frequency electronic equipment and power electronic devices, the dynamic performance of switching devices is one of the important indicators, and a double-pulse test circuit is usually used to test the dynamic performance of switching devices. In

A doubling integral for G 2

Israel Journal of Mathematics, 2015
We introduce a new integral representation for the standard L-function of an irreducible cuspidal automorphic representation of the exceptional group G2, and also for the twist of this L-function by an arbitrary character. Because our construction unfolds to a matrix coefficient rather than a Whittaker function, it applies to non-generic ...

Structural biology of ferritin nanocages

FEBS Letters, EarlyView.
Ferritin is a conserved iron‐storage protein that sequesters iron as a ferric mineral core within a nanocage, protecting cells from oxidative damage and maintaining iron homeostasis. This review discusses ferritin biology, structure, and function, and highlights recent cryo‐EM studies revealing mechanisms of ferritinophagy, cellular iron uptake, and ...

Calculation of a Deuterium Double Shock Hugoniot from Ab initio Simulations

, 2001
We calculate the equation of state of dense deuterium with two ab initio simulations techniques, path integral Monte Carlo and density functional theory molecular dynamics, in the density range of 0.67 < rho < 1.60 g/cc.

Tau acetylation at K331 has limited impact on tau pathology in vivo

FEBS Letters, EarlyView.
We mapped tau post‐translational modifications in humanized MAPT knock‐in mice and in amyloid‐bearing double knock‐in mice. Acetylation within the repeat domain, particularly around K331, showed modest increases under amyloid pathology. To test functional relevance, we generated MAPTK331Q knock‐in mice.

Electron impact ionization cross sections of C2H4 molecule

Chemical Physics Impact, 2020
In this paper, we have investigated partial and total integral ionization cross sections of C2H4 molecule by Jain-Khare semiempirical approach during the electron impact. They show good agreement with available data.

A Novel Delay-Product-Type Functional Method to Extended Dissipativity Analysis for Markovian Jump Neural Networks

IEEE Access, 2021
This paper studies the problem of extended dissipativity analysis for Markovian jump neural networks (MJNNs) with time-varying delay. Combining Wirtinger-based double integral inequality and S-procedure lemma, a novel double integral-based delay-product ...

Quantum Instantons and Quantum Chaos

, 2001
Based on a closed form expression for the path integral of quantum transition amplitudes, we suggest rigorous definitions of both, quantum instantons and quantum chaos.
