Abstract: Disclosed is a massager, including a massager body and two massage elements arranged on a circumferential wall surface on opposite sides of an axis of the massager body; the two massage elements perform synchronized but opposite-direction oscillation; and the oscillation is linear oscillation or orbital oscillation. Relative oscillation of the massage elements can cover both sides of a massage area, effectively solving the problem of uneven local pressure caused by unilateral stimulation. The synchronized but opposite-direction oscillation reduces discomfort caused by asynchronous stimulation, providing a user with more natural and comfortable massage experience.

Abstract: The present disclosure relates to a conductive paste based on seed silver powder and a preparation method therefor, belonging to the technical field of photovoltaic cells. The conductive paste includes 10-85 wt % seed silver powder, 2-5 wt % glass frit, and 8-12 wt % organic vehicle, with the balance being spherical silver powder. The seed silver powder uses base metal powder as a matrix. Silver is grown on the surface of the matrix via liquid-phase reduction using a supported agent. After calcination, multiple silver pores are formed in the surface of the base metal powder. After photoinduced silver electroplating, “silver anchors” are formed interspersed in the sintered layer. This increases the contact area between the sintered layer and the electroplated layer, reduces the resistivity of the grid electrode, enhances the interlayer bonding strength, mitigates resistance increase, effectively improves the photoelectric conversion efficiency, and reduces the cost of the conductive paste.

Abstract: The subject technology receives a query. The subject technology generates a set of query blocks based on parsing the query. The subject technology stores query block metadata for each query block from the set of query blocks. The subject technology restores a set of logical query block boundaries. The subject technology performs a hash-based query block matching. The subject technology generates, after performing the hash-based query block matching, a final query plan. In an example, if a (same) query is executed again the same logical query blocks would produce the same metadata (e.g., identifier, name and hash). This metadata can be used to match logical query blocks between multiple executions of the same query.
