Relative Arbitrage Opportunities With Interactions Among N Investors

Mathematical Finance, EarlyView.
ABSTRACT The relative arbitrage portfolio outperforms a benchmark portfolio over a given time‐horizon with probability one. With market price of risk processes depending on the market portfolio and investors, this paper analyzes the multi‐agent optimization of relative arbitrage opportunities in the coupled system of market and wealth dynamics.

Thermal electron-hydrogen laser assisted three-body scattering dynamics

Physics Open
Laser-assisted scattering (LAS) refers to the interaction of particles, such as electrons and atoms, in the presence of an external laser field. This process is vital in fields like radiation-matter interaction, plasma physics, laser cooling, medical ...

Deciphering pro‐arrhythmogenic mechanisms of EPAC in human atrial cardiomyocytes

The Journal of Physiology, EarlyView.
Abstract figure legend This study aimed to investigate the effect of exchange proteins directly activated by cAMP (EPAC) on the regulation of human atrial cardiomyocyte electrophysiology and their potential involvement in the onset of atrial fibrillation (AF).

Complete Monotonicity of a Difference Between the Exponential and Trigamma Functions and Properties Related to a Modified Bessel Function

, 2013
In the paper, the authors find necessary and sufficient conditions for a difference between the exponential function αeβ/t, α, β > 0, and the trigamma function ψ(t) to be completely monotonic on (0,∞).While proving the complete onotonicity, the ...

Trafficking and potentiation of Nav1.7 and Nav1.8 channels are mediated by IQGAP1

The Journal of Physiology, EarlyView.
Abstract figure legend IQGAP1 binds to the voltage‐gated Nav1.7 and Nav1.8 channels and TRPA1 channels in sensory neurons. Inflammatory mediators (IM), including PGE2 and TNFα, released during nerve injury and inflammation activate intracellular signalling messengers such as PKA, p38 MAPK and Cdc42 through their respective receptors.

Developmental mechanisms contributing to non‐linear firing dynamics in spinal motoneurons of the postnatal mouse

The Journal of Physiology, EarlyView.
Abstract figure legend. In this study, we describe how persistent inward currents (PICs) and nonlinear firing dynamics mature in slow‐type (green) and fast‐type (purple) motoneurons (MNs) during the second and third postnatal weeks of development in mice.

The Meijer transformation of generalized functions

International Journal of Mathematics and Mathematical Sciences, 1987
This paper extends the Meijer transformation, Mμ, given by (Mμf)(p)=2pΓ(1+μ)∫0∞f(t)(pt)μ/2Kμ(2pt)dt, where f belongs to an appropriate function space, μ ϵ (−1,∞) and Kμ is the modified Bessel function of third kind of order μ, to certain generalized ...

Functional inequalities involving Bessel and modified Bessel functions of the first kind

Expositiones Mathematicae, 2008
Since the sine and cosine functions and the hyperbolic sine and cosine functions are particular cases of Bessel and modifed Bessel functions, the author extends the inequality \(\cosh x-1\), where \(\Gamma\) is Euler gamma function and \(I_{p}(x)\) is the modified Bessel function of first kind. Some properties and inequalities satisfied by \(G_{p}(x)\)

Myelin Maintenance and Addition Regulate Synaptic Plasticity in the Adult Mouse Cortex

Glia, Volume 74, Issue 12, December 2026.
We report that existing myelin allows neurons to remain plastic throughout life, while new myelin progressively stabilises synapses along the basal but not apical dendrites of layer V pyramidal neurons in the motor cortex. ABSTRACT Myelin has the capacity to affect synapse number or plasticity across the lifespan.
