Abstract: A cooler having an optimized coating structure for an electric vehicle power module is provided. The cooler includes a metal cooling substrate and a coating structure. The coating structure has at least a barrier layer and a function layer. The barrier layer is formed on the metal cooling substrate. The barrier layer is a nickel coating layer or a nickel alloy coating layer having a thickness of between 0.1 ?m and 0.5 ?m. The function layer is a silver/silver alloy coating layer, or a copper/copper alloy coating layer having a thickness of between 0.1 ?m and 0.5 ?m.

Abstract: Described herein are specific CHO genomic sites for targeted insertion of exogenous genes. The sites are located within a sequence selected from SEQ ID NOs: 1-16.

Abstract: A handheld device includes a body and a back cover. The body has a back portion covered by the back cover. The back cover includes a yielding layer and a rigid layer. The yielding layer has an outer surface and an inner surface opposite to each other. The inner surface faces the back portion. The rigid layer is formed on the inner surface and locked to the body. The rigid layer has a hole exposing the back portion and covered by the yielding layer. When a portion of the yielding layer corresponding to the hole is pressed, the portion of the yielding layer is elastically deformed to closely lean on the back portion, and the locked body and rigid layer are released due to a force between the portion of the yielding layer and the back portion, such that the back cover may depart from the body.

Abstract: A handheld electronic apparatus comprises a touch panel, a front cover and a display panel. The front cover has a support portion with a first opening. The touch panel is placed on the support portion and covers the first opening. The touch panel comprises a touch panel body and a flexible printed circuit (FPC). The touch panel body has a first substrate having a notch configured to accommodate one end of the flexible printed circuit connected to the touch panel body. When the touch panel is assembled with the front cover, the flexible printed circuit will not be too-sharply bent due to the notch design.
