Reut and Beck columns: effects of end gravity forcé, translation and rotational inertias
The stability of Reut and Beck columns subjected to any combination of gravity and non-conservative (fixed-line of follower) comprenssive axial forces is presented using the dynamic formulation.

Sensitivity of the Intensity and Structure of Tropical Cyclones to Tropospheric Stability Conditions
The intensity of tropical cyclones (TCs) is controlled by their environmental conditions. In addition to the sea surface temperature, tropospheric temperature lapse rate and tropopause height are highly variable.

Field theory of bi- and tetracritical points: Relaxational dynamics [PDF]
We calculate the relaxational dynamical critical behavior of systems of $O(n_\|)\oplus O(n_\perp)$ symmetry by renormalization group method within the minimal subtraction scheme in two loop order.

Perturbations and Stability of Static Black Holes in Higher Dimensions [PDF]
In this chapter we consider perturbations and stability of higher dimensional black holes focusing on the static background case. We first review a gauge-invariant formalism for linear perturbations in a fairly generic class of (m+n)-dimensional ...

75-mm Wingspan Fixed-Wing Nano Air Vehicle With a Novel Aircraft Configuration
The development of a fixed-wing nano air vehicle that fits inside a cube of 75 mm is described in this paper. A novel aircraft configuration that satisfies the static and dynamic stability and the mission performance requirements is developed.

Stability of the solutions of the Gross-Pitaevskii equation
We examine the static and dynamic stability of the solutions of the Gross-Pitaevskii equation and demonstrate the intimate connection between them. All salient features related to dynamic stability are reflected systematically in static properties.
