Stability of the solutions of the Gross-Pitaevskii equation
, 2005 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.

Stability in dynamical astronomy [PDF]
Proceedings of the National Academy of Sciences, 1978 Hill's concept of stability is generalized and its relation to bifurcation theory is shown. A quantitative measure of stability is introduced that allows the comparison of the stability of different astronomical systems. Theoretical stability limits for triple stellar systems, for planetary systems, and for satellite systems are established.

Electricity, 2023 In isolated power systems with very high instantaneous shares of renewables, additional inertia should be used as a complementary resource to battery energy storage systems (BESSs) for improving frequency stability, which can be provided by synchronous ...

Dynamic Stabilization of the Trunk [PDF]
Journal of Orthopaedic & Sports Physical Therapy, 1985 The lumbopelvic region, because it is the hub of our antigravity weightbearing, is the most vulnerable area for spraining and straining tissues. It is also, however, the most difficult area to treat because of our inability to completely control the healing of these injured tissues.

Optimal bacterial resource allocation: metabolite production in continuous bioreactors
Mathematical Biosciences and Engineering, 2020 We show novel results addressing the problem of synthesizing a metabolite of interest in continuous bioreactors through resource allocation control. Our approach is based on a coarse-grained self-replicator dynamical model that accounts for microbial ...

The unpredictably eruptive dynamics of spruce budworm populations in eastern Canada
Population Ecology, EarlyView.We examine historical population data for spruce budworm from several locations through the period 1930–1997, and use density‐dependent recruitment curves to test whether the pattern of population growth over time is more consistent with Royama's (1984; Ecological Monographs 54:429–462) linear R(t) model of harmonic oscillation at Green River New ...

Simulation research on axial dynamic stability of transformer winding under reclosing condition
Zhejiang dianliReclosing during a permanent fault subjects the transformer to secondary impacts， thereby increasing the likelihood of transformer damage. In this paper， a computational model for calculating the leakage magnetic field of a three-winding transformer ...
