Aging Is a Key Driver for Adult Acute Myeloid Leukemia
Aging and Cancer, EarlyView.Acute myeloid leukemia (AML) is a classical age‐related hematologic malignancy, and a key driver of AML is aging, which profoundly regulates intrinsic factors such as genomic instability, epigenetic reprogramming, and metabolic dysregulation, and alters bone marrow microenvironment.

Dynamics and Efficient Numerical Simulation of a Fractional-Order T System
Fractal and FractionalIn this paper, we propose and numerically investigate a fractional T system. As a fractional generalization of the classical T model, the fractional order serves as a memory parameter governing the system dynamics.

Mutant NPM1 in Acute Myeloid Leukemia Initiation and Maintenance
Aging and Cancer, EarlyView.NPM1 mutations drive acute myeloid leukemia by acting as neomorphic transcriptional regulators that cooperate with Menin–MLL and XPO1 to sustain HOX/MEIS1 expression and block differentiation. Targeting these mutant‐specific transcriptional dependencies provides a rational therapeutic strategy for NPM1‐mutated AML.

Representations of the fractional d’Alembertian and initial conditions in fractional dynamics
Chaos, Solitons & FractalsWe construct representations of complex powers of the d'Alembertian operator $\Box$ in Lorentzian signature and pinpoint one which is self-adjoint and suitable for classical and quantum fractional field theory. This self-adjoint fractional d'Alembertian is associated with complex-conjugate poles, which are removed from the physical spectrum via the ...

Long Run and Cyclical Dynamics in the US Stock Market [PDF]
This paper examines the long-run dynamics and the cyclical structure of various series related to the US stock market using fractional integration. We implement a procedure which enables one to consider unit roots with possibly fractional orders of ...

Relative fractional dynamics of stock markets
This paper analyses motion of stock markets (SM) in the perspective of fractional calculus and introduces the concept of relative fractional dynamics. The SM are characterized by long-range correlations and persistent memory. These features are found

Discrete Memristive Hindmarsh-Rose Neural Model with Fractional-Order Differences
Fractal and FractionalDiscrete systems can offer advantages over continuous ones in certain contexts, particularly in terms of simplicity and reduced computational costs, though this may vary depending on the specific application and requirements.
