NettetAn attenuated total reflectance infrared spectroelectrochemical (ATR-IR-SEC) technique has been developed that uses a surface-proximal doped Si ATR crystal as both the ATR optical element and the working electrode. This allows redox processes of monolayers of molecules attached to the Si surface to be probed through changes in their molecular … NettetAround 600 of these 2000 orbits are linearly stable, therefore of astronomical interest. • We analyzed distribution of stable orbits as function of masses and orbits’ topologies. • …

Nettet2. des. 2014 · We find that this property makes networks far more linearly stable than if the links (predator–prey interactions) were placed randomly between species, or according to existing structural models. A simple model we propose to capture this feature shows that networks can, in fact, become more stable with size and complexity, suggesting a … tensura kenyaNettet4. jun. 1998 · ABSTRACT. Fluid flowing down an inclined plane commonly exhibits a fingering instability in which the contact line corrugates. We show that below a critical inclination angle the base state before the instability is linearly stable. Several recent experiments explore inclination angles below this critical angle, yet all clearly show the ... tensura kekaisaran timurNettet13. sep. 2024 · In the above, \({\mathring{R}}\) is the action of the curvature tensor on symmetric 2-tensors (see ()).(M, g) is linearly unstable if it is not linearly stable.The coindex of a quadratic form is the dimension of the maximal subspace on which it is positive definite.
