Buildings, 2022 With the development of the Steel Truss Corridor (STC) toward long-span and gentle development, human-induced vibration often causes large lateral vibration problems and time-delay effects of the STC, which will have a non-negligible impact on the ...

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 ...

Stability of Boolean and Continuous Dynamics [PDF]
Physical Review Letters, 2011 Regulatory dynamics in biology is often described by continuous rate equations for continuously varying chemical concentrations. Binary discretization of state space and time leads to Boolean dynamics. In the latter, the dynamics has been called unstable if flip perturbations lead to damage spreading.

Dynamics and stability of the Gödel universe [PDF]
Classical and Quantum Gravity, 2004 We use covariant techniques to describe the properties of the Godel universe and then consider its linear response to a variety of perturbations. Against matter aggregations, we find that the stability of the Godel model depends primarily upon the presence of gradients in the centrifugal energy, and secondarily on the equation of state of the fluid ...

Specialized interfaces of Smc5/6 control hinge stability and DNA association
Nature Communications, 2017 Structural Maintenance of Chromosomes (SMC) complexes maintain genome integrity by regulating the segregation of chromosomes. Here, Altet al. describe the structure of the heterodimeric Smc5/6-hinge from fission yeast and define functional features ...

Sensors, 2023 The analysis of the stability of human gait may be effectively performed when estimates of the base of support are available. The base of support area is defined by the relative position of the feet when they are in contact with the ground and it is ...

Experimental Research on the Dynamic Stability of Internal Turning Tools for Long Overhangs
Journal of Manufacturing and Materials Processing, 2023 The roughness origin of machined surfaces is caused by the following physical causes: the copying of the shape and the roughness of the cutting part of the tool into the workpiece, the existence of vibration of the tool, and the existence of the build-up

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.

Evaluation of Static and Dynamic Stability and Its Relationship With Fear of Falling in Patients With Mild to Moderate Knee Osteoarthritis [PDF]
Journal of Rehabilitation, 2023 Objective Knee osteoarthritis is one of the most common musculoskeletal disorders affecting balance. It is also a risk factor for falling in older people. People with a history of falling, whether being injured or not, acquire a fear of potential falling,
