Transient Dynamics of a Food Chain Model with Vigilance in the Biparameter Spaces
Complexity, Volume 2023, Issue 1, 2023., 2023 This article focuses on the asymptotic and transient behavior of a food chain model with vigilance in the biparameter spaces. Firstly, the local asymptotic stability conditions of the positive equilibrium point are obtained. Then, the transient dynamical behavior of the positive equilibrium point is analyzed based on eight parameters.

Role of A‐Site Composition in Charge Transport in Lead Iodide Perovskites
Advanced Energy and Sustainability Research, Volume 3, Issue 11, November 2022., 2022 The electronic properties of metal halide perovskites are measured with time‐resolved microwave conductivity, as a function of A‐site composition. It is found that a small percentage of Cs leads to a larger carrier mobility and lifetime and that compositions with a tolerance factor close to 0.9 generally show lower performance than those closer to 0.8 ...

Breathing Dissipative Soliton Molecule Switching in a Bidirectional Mode‐Locked Fiber Laser
Advanced Photonics Research, Volume 3, Issue 4, April 2022., 2022 The transient switching dynamics of breathing soliton molecules (BSMs) are explored in a bidirectional ultrafast fiber laser, specifically triggered at different parameter spaces of saturable absorption with manipulation polarization. The all‐optical switching of breather molecules of two or three solitons with different binding temporal separation has

Search for heavy quasistable leptons
Physics Letters B, 1972 Abstract Negative results of a search for heavy quasistable charge leptons at the IHEP accelerator are reported. For the selection of heavy leptons a system of scintillation and gas Cherenkov counters was used. The upper limit estimation of the differential cross-section for heavy lepton production in pN-collisions at E p = 70 GeV is d 2 δ λ (

Point-form dynamics of quasistable states [PDF]
Journal of Mathematical Physics, 2013 We present a field theoretical model of point-form dynamics which exhibits resonance scattering. In particular, we construct point-form Poincaré generators explicitly from field operators and show that in the vector spaces for the in-states and out-states (endowed with certain analyticity and topological properties suggested by the structure of the S ...

Search for heavy quasistable leptons
Nuclear Physics B, 1973 Negative results of a search for heavy quasistable charged leptons at the IHEP accelerator are reported. For the selection of heavy leptons a system of scintillation and gas Cerenkov counters was used. The upper limit estimations of the differential cross sections for heavy lepton production in pN collisions at Ep = 70 GeV are, for example, d2 σ/dpω (p

On the mass and width of the -boson and other relativistic quasistable particles [PDF]
Nuclear Physics B, 2000 The ambiguity in the definition for the mass and width of relativistic resonances is discussed, in particular for the case of the Z-boson. This ambiguity can be removed by requiring that a resonance's width $Γ$ (defined by a Breit-Wigner lineshape) and lifetime $τ$ (defined by the exponential law) always and exactly fulfill the relation $Γ= \hbar/τ ...

Eventual practical stability of impulsive differential equations with time delay in terms of two measurements [PDF]
, 2005 In this paper we introduce a new stability—eventual practical stability for impulsive differential equations with time delay. By using Lyapunov functions and comparison principle, we will get some criteria of eventual practical stability, eventual ...

Мера устойчивости многокритериальной задачи целочисленного линейного программирования с параметрическим принципом оптимальности [PDF]
, 2022 In this paper, we consider a multicriteria integer linear programming problem with a parametric principle of optimality. Parameterization is realized by dividing the set of criteria into several disjoint groups (subsets) of criteria ordered by importance,
