Abstract: The present invention relates generally to methods of accurately quantifying HER2 and/or p95 expression in subjects with a HER2 positive cancer and indicating the risk of brain relapse in such patients.

Abstract: Disclosed herein are sliders with at least one notch-cut in the trailing pad, methods of making them, and data storage devices comprising them. In some embodiments, a slider comprises a leading-edge surface, a trailing-edge surface, and an air-bearing surface (ABS) that includes a trailing pad situated closer to the trailing-edge surface than to the leading-edge surface, wherein the trailing pad comprises at least one notch-cut (e.g., two notch-cuts) in a trailing side of the trailing pad. The at least one notch-cut provides higher pressure at the recording head situated in the trailing pad and higher thermal flight control efficiency without a commensurate increase in touch-down power. As a result, the temperature around the recording head is lower than without the at least one notch-cut, thereby improving the lifetime of the recording head and data storage device.

Abstract: A 3D printing head, a 3D printing device and a control method of the 3D printing head are provided. The 3D printing head includes a feeding pipe, provided with an opening at its bottom; a shutter, disposed at the opening and slidably connected to the bottom, where the opening includes a region occluded by the shutter and a region not occluded by the shutter, and the region not occluded by the shutter forms a discharge port of the 3D printing head, where the discharge port includes a first end and a second end, and the first end and the second end define a length of the discharge port; and a drive apparatus, used to drive the shutter sliding at the opening to adjust the length of the discharge port. The 3D printing head makes it possible to take both printing efficiency and printing accuracy into account.

Abstract: Disclosed herein are embodiments of sliders in which the length of the slider is less than or equal to its width. Also disclosed are data storage devices (e.g., hard disk drives) comprising such sliders. The sliders may include one or more air-bearing surface features to compensate for the lower aspect ratio and to meet performance targets (fly height, roll stiffness, etc.). Such features may include, for example, a trailing-edge pad (which may include an efficiency-flattening hole), a first cavity between a first side of the trailing-edge pad and a first side edge, and a non-intersecting second cavity between a second side of the trailing-edge pad and a second side edge. A slider may also or alternatively include a leading pad and, in some embodiments, a particle trapping structure between the leading pad and the slider's leading edge.

Abstract: Disclosed here is a ramp for receiving a lift tab of a hard disk drive. The ramp comprises a first side and a second side, where the first side is spaced apart from the second side. The ramp also comprises an inclined surface along which the lift tab slides as it moves in a first direction to remove a read/write head from a disk of the hard disk drive. The inclined surface inclines from a leading edge of the ramp to an intermediate edge of the ramp in the first direction. The inclined surface has a width that is generally perpendicular to the first direction and extends from the first side to the second side. The inclined surface has a width that is generally perpendicular to the first direction and extends from the first side to the second side. The tapered portion defines an oblique angle relative to the first direction.
