Abstract: A drive carrier includes a frame to receive and carry a media drive, a handle assembly, and a latching assembly having a helical compression spring and a latch. The handle assembly having a handle is pivotably connected to the frame and configured to rotate relative to the frame between open and closed positions. The handle assembly in its closed position, is configured to engage to a drive cage and hold the drive carrier in the drive cage. The latch is pivotably connected to the frame and rotatable between latched and unlatched positions. A second locking arm of the latch in its latched position, is engageable with a first locking arm of the handle to retain the handle in the closed position. The helical compression spring is arranged at an acute angle relative to the frame and applies force on the latch to bias the latch towards the latched position.

Abstract: Computer-implemented processes for precision therapeutic biomarker screening for cancer include using a model-based overlapping clustering framework to assess large numbers of possible drugs and drug combinations against patient data, including cell line responsiveness. A multivariate regression model has been developed, along with a latent overlapping cluster indicator variable. The techniques employ a new finite mixture of multivariate regression (FMMR) model and expectation-maximization (EM) algorithm for modeling. The techniques can analyze large amounts of drug data and identify complex overlapping drug clusters, as well as cluster-wise drivers that facilitate identification of new drugs for treating pathologies, such as cancer, in patients.

Abstract: Various embodiments include a memory device that recovers from write errors and read errors more quickly relative to prior memory devices. Certain patterns of write data and read data may result on poor signal quality on the memory interface between memory controllers and memory devices. The disclosed memory device, synchronously with the memory controller, scrambles read data before transmitting the data to the memory controller and descrambles received from the memory controller. The scrambling and descrambling results in a different pattern on the memory interface even for the same read data or write data. Therefore, when a write operation or a read operation fails, and the operation is replayed, the pattern transmitted on the memory interface is different when the operation is replayed. As a result, the memory device more easily recovers from data patterns that cause poor signal quality on the memory interface.

Abstract: Examples include a computing system including a heater element for heating a processor device installed in the computing system. The computing system includes a chassis, a circuit board assembly housed in the chassis and a heat sink assembly disposed on the chassis to form a cover of the chassis. The circuit board assembly includes a processor package including a substrate having a first portion and a second portion. The processor package includes the processor device disposed on the first portion of the substrate. The heater element disposed on the second portion of the substrate. In the computing system, the heat sink assembly is disposed on the chassis such that a gap separates the heat sink assembly and the heater element.

Abstract: Systems, apparatuses, and methods described herein provide heat sinks that can be incorporated into chassis, yet be compatible with edge devices that contain many different combinations of hardware that can be arranged in many different ways on circuit boards. In one example, a pattern of fittings on an interior-facing side of the heat sink are configured to mate with fittings on a first side of an adapter pedestal. A second side of the adapter pedestal is configured to thermally couple with an electronic component housed within the chassis when the heat sink is fully seated and the pedestal is properly coupled to the heat sink.

It further comprises a module base board, a second connector attached thereto and a lever handle pivotally attached to the base frame and coupled to the module base board.
