Systems and methods for annotating electronic meetings are generally provided. In one embodiment, an SSL device includes a composite structure having a composite CTE temperature dependency, a formation structure on the composite structure, and an SSL structure on the formation structure. Each bead bears a unique optical signature comprising a predefined number of unique reporters, where each reporter comprises a predefined combination of different fluorochromes. The invention also provides articles of manufacture comprises the PSS and presents an effective method for killing the LTCs. The flow is resumed to retrieve the tool. The peeling cylinder is constituted by a polygonal-shaped angular columnar body having, as coating film pass-through holes, rows K of small holes and rows L of small holes and projection rings provided alternately in multiple rows along a direction perpendicular to a rotating direction of the peeling roll.
