Impulsive Fractional Cohen-Grossberg Neural Networks: Almost Periodicity Analysis
Fractal and Fractional, 2021 In this paper, a fractional-order Cohen–Grossberg-type neural network with Caputo fractional derivatives is investigated. The notion of almost periodicity is adapted to the impulsive generalization of the model.

Fractional moments of automorphic $L$-functions [PDF]
St. Petersburg Mathematical Journal, 2011 The Riemann zeta-function is defined by \(\zeta (s) = \sum_{n=1}^{\infty} n^{-s}\) in \(\text{Re}\, s > 1\). For \(T \geq 2\), \textit{D. R. Heath-Brown} [J. Lond. Math. Soc., II. Ser. 24, 65--78 (1981; Zbl 0431.10024)] investigated the behaviour of the integral \[ I_k (T) := \int_{1}^{T} \left | \zeta \left ( \frac {1}{2} + it \right ) \right |^{2k} \,

Analytical Solution of Generalized Space-Time Fractional Cable Equation
Mathematics, 2015 In this paper, we consider generalized space-time fractional cable equation in presence of external source. By using the Fourier-Laplace transform we obtain the Green function in terms of infinite series in H-functions.

Robust Color Images Watermarking Using New Fractional-Order Exponent Moments
IEEE Access, 2021 Robust watermarking is a valuable methodology used in protecting the copyright and securing digital images. In this paper, new fractional-order multi-channel orthogonal exponent moments (MFrEMs) and their invariants to geometric transformations are ...

Phosphatidylinositol 4‐kinase as a target of pathogens—friend or foe?
FEBS Letters, EarlyView.This graphical summary illustrates the roles of phosphatidylinositol 4‐kinases (PI4Ks). PI4Ks regulate key cellular processes and can be hijacked by pathogens, such as viruses, bacteria and parasites, to support their intracellular replication. Their dual role as essential host enzymes and pathogen cofactors makes them promising drug targets.

Fractional Corner Charge of Sodium Chloride
Physical Review X, 2021 Recent developments in higherorder topological phases have revealed the relationship between nontrivial multipole moments in the bulk and the emergence of fractionally quantized charges at the boundary.

Protein pyrophosphorylation by inositol pyrophosphates — detection, function, and regulation
FEBS Letters, EarlyView.Protein pyrophosphorylation is an unusual signaling mechanism that was discovered two decades ago. It can be driven by inositol pyrophosphate messengers and influences various cellular processes. Herein, we summarize the research progress and challenges of this field, covering pathways found to be regulated by this posttranslational modification as ...

Fractional‐order complex correntropy algorithm for adaptive filtering in α‐stable environment
Electronics Letters, 2021 In adaptive filtering applications, the Gaussian distribution cannot be used to model the signal/noise with frequent spikes accurately. In fact, the rational model to simulate the behaviour of such signal/noise is the α‐stable distribution process.

FEBS Letters, EarlyView.We reconstituted Synechocystis glycogen synthesis in vitro from purified enzymes and showed that two GlgA isoenzymes produce glycogen with different architectures: GlgA1 yields denser, highly branched glycogen, whereas GlgA2 synthesizes longer, less‐branched chains.
