Harmonic mappings and finite valency of analytic functions

Учёные записки Казанского университета: Серия Физико-математические науки, 2018
The harmonic mappings of a circle into domains that can be cut into a finite number of convex subdomains has been studied. An estimate of the valency of holomorphic mappings of a circle composed of analytical components of the harmonic function has been ...

Spatiotemporal and quantitative analyses of phosphoinositides – fluorescent probe—and mass spectrometry‐based approaches

FEBS Letters, EarlyView.
Fluorescent probes allow dynamic visualization of phosphoinositides in living cells (left), whereas mass spectrometry provides high‐sensitivity, isomer‐resolved quantitation (right). Their synergistic use captures complementary aspects of lipid signaling. This review illustrates how these approaches reveal the spatiotemporal regulation and quantitative

Some new problems about the Smarandache function and related problems [PDF]

, 2007
For any positive integer n, the famous F.Smarandache function S(n) is defined as the smallest positive integer m such that njm!. That is, S(n) = min fm : m 2 N; njm!g.

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.

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 ...

A randomised controlled trial investigating the effect of n-3 long-chain polyunsaturated fatty acid supplementation on cognitive and retinal function in cognitively healthy older people: the Older People And n-3 Long-chain polyunsaturated fatty acids (OPAL) study protocol [ISRCTN72331636]. [PDF]

, 2006
The number of individuals with age-related cognitive impairment is rising dramatically in the UK and globally. There is considerable interest in the general hypothesis that improving the diet of older people may slow the progression of cognitive decline.

Circularly polarized electroluminescence from topologically chiral [2]catenane-based neutral radicals with tunable deep-red emission

Nature Communications
Stable organic radicals with unique luminescence have demonstrated great importance in photoelectromagnetic materials and have found broad applicability in the field of organic light-emitting diode (OLEDs). Aiming to further extend their application into

Initial Coefficient Bounds for Bi-Close-to-Convex Classes of n-Fold-Symmetric Bi-Univalent Functions

Axioms
In this article, the strong class of bi-close-to-convex functions of order α and β in n-fold symmetric bi-univalent functions, which is the subclass of σ, is introduced.

Properties of the partition function of N = 2 $$ \mathcal{N}=2 $$ supersymmetric QCD with massive matter

Journal of High Energy Physics, 2019
We study the different quantum phases that occur in massive N = 2 $$ \mathcal{N}=2 $$ supersymmetric QCD with gauge groups SU(2) and SU(3) as the coupling Λ/M is gradually increased from 0 to infinity.

On Musielak N-functions

, 2018
In this paper, the concept of Musielak N-functions and Musielak-Orlicz spaces generated by them well be introduced. Facts and results of the measure theory will be applied to consider properties, calculus and basic approximation of Musielak N-functions and their Musielak-Orlicz spaces. Finally, the relationship between Musielak N-functions and Musielak-
