On the one-dimensional reggeon model: eigenvalues of the Hamiltonian and the propagator

European Physical Journal C: Particles and Fields, 2019
The effective reggeon field theory in zero transverse dimension (“the toy model”) is studied. The transcendental equation for the eigenvalues of the Hamiltonian of this theory is derived and solved numerically.

Vlasov tokamak equilibria with shearad toroidal flow and anisotropic pressure

, 2015
By choosing appropriate deformed Maxwellian ion and electron distribution functions depending on the two particle constants of motion, i.e. the energy and toroidal angular momentum, we reduce the Vlasov axisymmetric equilibrium problem for quasineutral ...

Synthesis of Telechelic‐Type Polypeptides Functionalized with Aromatic Units and the Characterization of Their Structures and Thermal Properties

Macromolecular Rapid Communications, EarlyView.
Polypeptide chains were extended from both ends of aromatic diamines by chemoenzymatic polymerization, resulting in the synthesis of telechelic polyglycines (TPG) and polyalanines (TPA). These telechelic polymers assembled into branched nanofibrils through π‐π stacking of aromatic rings, with the polymer backbones bent at the aromatic unit.

Exact Mathematical Solution for Maximum Transient Offtracking Calculation of a Single-Unit Vehicle Negotiating Circular Curves

Applied Sciences
The low-speed turning maneuverability of vehicles is closely related to a well-known offtracking phenomenon which occurs when the rear wheels of a turning vehicle deviate towards the inside of a horizontal curve. Although numerous mathematical models and

Analytical solution of non-exponential decay in a simple resistor-capacitor circuit using the Lambert-Tsallis Wq function [PDF]

Revista Brasileira de Ensino de Física
In this work, using the Lambert-Tsallis Wq function, we present the analytical solution for the non-exponential decay in a simple electrical circuit composed by two resistors, two capacitors and a DC power supply.

Effect of Magnetic Field and Temperature on the Excess Minority Carrier Density in the Base of a Radial Junction Solar Cell

Nano Select, EarlyView.
This study explores how magnetic field and temperature influence excess minority carrier density in a radial‐junction silicon solar cell. Using an analytical model based on Bessel functions, key trends are revealed, including thermal insensitivity in a specific magnetic field range.

Power expansions for solution of the fourth-order analog to the first Painlev\'{e} equation

, 2005
One of the fourth-order analog to the first Painlev\'{e} equation is studied. All power expansions for solutions of this equation near points $z=0$ and $z=\infty$ are found by means of the power geometry method. The exponential additions to the expansion

Physicochemical Necessary and Sufficient Conditions for Superferromagnetism in High‐Resolution Magnetic Particle Imaging

Small, EarlyView.
This study investigates how strong dipole–dipole coupling in linear chains of synthesized superparamagnetic nanoparticles induces superferromagnetism, enhancing Magnetic Particle Imaging (MPI) resolution. A positive feedback model predicts key magnetic behaviors, such as coercivity, and guides nanoparticle synthesis.

Analytic solutions of $q$-$P(A_1)$ near its critical points

, 2016
For transcendental functions that solve non-linear $q$-difference equations, the best descriptions available are the ones obtained by expansion near critical points at the origin and infinity.
