The present invention describes leucascandrolide analogs of the formula, intermediates of the formula, pharmaceutical compositions containing the same, methods for preventing cell proliferation, and methods for treating cancers and other proliferative diseases. A modular housing dispenses disposable hand towels as an alternative to traditional hand towels or shower towels used to clean and dry hands prior to leaving a bathroom setting. In addition, position information required for levitation control of a sample with a complicated shape is outputted by the image pickup device so that an instant at which the sample with a complicated shape changes to a spherical shape one can be specified visually. The temporal habit pattern is compared with current environmental parameters captured by sensors or current user feedback input from the user interface. The barrier layer can also extend onto the epitaxial region outside the multilayer conductive stack. Also, the substantially matching script and orientation are declared as the script and orientation of the image, if the computed concatenated VDV and HDV of the image substantially match with the reference VDV and HDV of the matching script and orientation, respectively.
