Efficient handling of stability problems in shell optimization by asymmetric ‘worst-case’ shape imperfection [PDF]
, 2008 The paper presents an approach to shape optimization of proportionally loaded elastic shell structures under stability constraints. To reduce the stability-related problems, a special technique is utilized, by which the response analysis is always ...

the predator-prey discrete system codimention- 2 bifurcations
پژوهشهای ریاضی, 2022 Introduction In population dynamics, discrete-time dynamical systems have been used to describe interaction between ecological species. Comparing to continuous-time dynamical systems, discrete-time models are more suitable to describe populations with ...

Multiple limit point bifurcation
Journal of Mathematical Analysis and Applications, 1980 In this paper we present a new bifurcation or branching phenomenon which we call multiple limit point bifurcation. It is of course well known that bifurcation points of some nonlinear functional equation G(u, λ) = 0 are solutions (u_0, λ_0) at which two distinct smooth branches of solutions, say [u(e), λ(e)] and [u^(e), λ^(e)], intersect ...

Advanced Science, EarlyView.Boiling Histrotripsy (BH), a mechanical form of focused ultrasound (FUS), allows for non‐invasive and non‐ionizing tissue destruction. Utilizing a BH treatment protocol that yielded bifurcating primary tumor growth responses, we found that immediate BH‐induced tumor growth control identifies tumors with acute reductions in antigen‐presenting cells (APC)

Largest Lyapunov Exponents and Bifurcations of Stochastic Nonlinear Systems
Shock and Vibration, 1996 Two commonly adopted expressions for the largest Lyapunov exponents of linearized stochastic systems are reviewed. Their features are discussed in light of bifurcation analysis and one expression is selected for evaluating the largest Lyapunov exponent ...

The lowest point of the continuous spectrum as a bifurcation point
Journal of Differential Equations, 1979 AbstractFor a class of monotone differential operators we show that the lowest point of the continuous spectrum of the linearization is a bifurcation point. By the method of upper and lower solutions we prove the existence of a global branch of positive solutions.

Selective Catalytic Production of Urea: Unravelling the Pairwise Competition on p‐d Alloy Catalysts
Advanced Science, EarlyView.Unraveling the complicated competition in urea electrosynthesis, this work investigates asymmetric p‐d alloys. We establish two stage‐specific descriptors, Anchoring Affinity and Coupling Propensity, to elegantly quantify thermodynamic bottlenecks.
