A class of solutions of the equation d(n²) = d(φ(n)) [PDF]

open access: yesNotes on Number Theory and Discrete Mathematics, 2023
For any positive integer n let d(n) and φ(n) be the number of divisors of n and the Euler's phi function of n, respectively. In this paper we present some notes on the equation d(n²) = d(φ(n)).

The mean value of the function d(n)/d*(n) in arithmetic progressions [PDF]

open access: yesNotes on Number Theory and Discrete Mathematics, 2023
Let d(n) and d*(n) be, respectively, the number of divisors and the number of unitary divisors of an integer n≥1. A divisor d of an integer is to be said unitary if it is prime over n/d.

Guidelines for the use and interpretation of assays for monitoring autophagy (4th edition)1

open access: yesAutophagy, 2021
In 2008, we published the first set of guidelines for standardizing research in autophagy. Since then, this topic has received increasing attention, and many scientists have entered the field.

Gauged D = 4 N $$ \mathcal{N} $$ = 4 supergravity

open access: yesJournal of High Energy Physics, 2023
We present the full Lagrangian and supersymmetry transformation rules for the gauged D = 4, N $$ \mathcal{N} $$ = 4 (half-maximal) supergravity coupled to an arbitrary number of vector multiplets. Using the embedding tensor formulation, the final results

All basic quantizations of $$D=3$$ D = 3 , $$N=1$$ N = 1 Lorentz supersymmetry

open access: yesEuropean Physical Journal C: Particles and Fields, 2023
By the supersymmetrization of a simple algebraic technique proposed in Lukierski and Tolstoy (Eur Phys J C 77:226, 2017) we obtain the complete classification of all basic (nonisomorphic) quantum deformations for the orthosymplectic Lie superalgebra ...

$$\theta $$ θ -diagram technique for $${\mathcal {N}}=1$$ N = 1 , $$d=4$$ d = 4 superfields

open access: yesEuropean Physical Journal C: Particles and Fields, 2023
We describe a diagrammatic procedure to carry out the Grassmann integration in super-Feynman diagrams of 4d theories expressed in terms of $${\mathcal {N}}=1$$ N = 1 superfields. This method is alternative to the well known D-algebra approach. We develop

N-(1-Deoxy-α-d-tagatopyranos-1-yl)-N-methylaniline (“d-Tagatose-N-methylaniline”)

open access: yesMolbank, 2018
Tagatosamines form in thermally-processed dairy products and contribute to the foods’ organoleptic and nutritional value. d-Tagatose-N-methylaniline (N-(1-deoxy-d-tagatos-1-yl)-N-methylaniline, 1-deoxy-1-(N-methylphenylamino)-d-tagatose) was synthesized ...

Carbon target as neutron source from 12C(d,n)13N and D(d,n)3He reactions

open access: yesЯдерна фізика та енергетика, 2018
Possibility to use carbon as a target material to generate fast neutrons from D(d,n)3He nuclear reaction and intermediate energy neutrons from 12C(d,n)13N nuclear reaction was studied. The experiment results were obtained to characterize an adsorption of
