COMPLETE CONTROLLABILITY CONDITIONS FOR LINEAR SINGULARLY PERTURBED TIME-INVARIANT SYSTEMS WITH MULTIPLE DELAYS VIA CHANG-TYPE TRANSFORMATION

Complete Controllability Conditions for Linear Singularly Perturbed Time-Invariant Systems with Multiple Delays via Chang-Type Transformation

The problem of complete controllability of a Steamer linear time-invariant singularly-perturbed system with multiple commensurate non-small delays in the slow state variables is considered.An approach to the time-scale separation of the original singularly-perturbed system by means of Chang-type non-degenerate transformation, generalized for the sy

Microtubule heterogeneity of Ornithogalum umbellatum ovary epidermal cells: non-stable cortical microtubules and stable lipotubuloid microtubules

Lipotubuloids, structures containing lipid bodies and microtubules, are described in ovary epidermalcells of Ornithogalum umbellatum.Microtubules of lipotubuloids can be fixed in electron microscope fixativecontaining only buffered OsO4 or in glutaraldehyde with OsO4 post-fixation, or in a mixture of OsO4 and glutaraldehyde[1].None of these substan
