The theory of differential equations has been widely known and developed in recent years. Many researchers have drawn attention to the problem of finding the stability region of a nonlinear dynamical system in technical models, which is a complicated issue in the stability theory of dynamical systems.

CTCF binding contributes to the establishment of a higher-order genome structure by demarcating the boundaries of large-scale topologically associating domains (TADs). However, despite the importance and conservation of TADs, the role of CTCF binding in their evolution and stability remains elusive.

Dynamic instability of thin rectangular plates subjected to uniform in-plane harmonic compressive load applied along two opposite edges are investigated in this paper. The dynamic stiffness method (DSM), as a consequence the dynamic stiffness matrices, is used to analyze the free vibration, the static stability, and dynamic instability of thin plates under different boundary conditions.

In this report, we examine the unsteady Stokes equations with nonhomogeneous boundary conditions. As an application of a Carleman estimate, we first establish log type stabilities for the solution of the equations from either an interior measurement of the velocity, or a boundary observation depending on the trace of the velocity and of the Cauchy stress tensor measurements on a part of the boundary.

The effects of several physical parameters on the water sheet oscillation are studied by determining the variation of the temporal growth rate with the wavenumber. It is found that a larger relative steam velocity to water velocity has a tendency to destabilize the water sheet with increased dynamic pressure. On the other hand, a larger ratio of steam boundary layer to the half water sheet thickness has a stabilizing effect on the water sheet oscillation.

This paper focuses on boundary control of distributed parameter systems (also called infinite dimensional systems). More precisely, a passivity based approach for the stabilization of temperature profile inside a well-insulated bar with heat conduction in a one-dimensional system described by parabolic partial differential equations (PDEs) is developed.

The jurisdictional boundaries among new and existing federal financial regulatory agencies should be drawn carefully to prevent mission overlap, and each of the federal financial regulatory agencies generally should have exclusive jurisdiction to issue and enforce rules to achieve its mission. Nevertheless, many emerging financial products and practices will raise issues relating to systemic risk, prudential regulation of financial firms, and consumer or investor protection.

As we have witnessed during this crisis, financial stress can spread easily and quickly across national boundaries. Yet, regulation is still set largely in a national context. Without consistent supervision and regulation, financial institutions will tend to move their activities to jurisdictions with looser standards, creating a race to the bottom and intensifying systemic risk for the entire global financial system.

This paper considers a trapped characteristic initial value problem for the spherically symmetric Einstein-Maxwell-scalar field equations. For an open set of initial data whose closure contains in particular Reissner-Nordstr¨m data, o the future boundary of the maximal domain of development is found to be a light-like surface along which the curvature blows up, and yet the metric can be continuously extended beyond it. This result is related to the strong cosmic censorship conjecture of Roger Penrose. ...

Many governments acknowledge that environmental degradation and climate change pose international and trans-boundary risks to human populations, economies, and ecosystems that could result in a worsening of poverty, social tensions, and political stability. To confront these global challenges, countries have negotiated various international agreements to protect the environment, reduce pollution, conserve natural resources, and promote sustainable growth.
