According to one embodiment, a disk device includes a disk-shaped recording medium, a base accommodating the recording medium, the base including a bottom wall, a sidewall on a peripheral portion of the bottom wall, and a rib on a part of an upper surface of the sidewall, a first cover on a part of the upper surface of the sidewall, and a second cover on a first surface of the rib and above the first cover. The rib includes a first region with a first width, a second region with a second width less than the first width, and the first surface with a fixed width around an entire circumference of the rib. The first region and the second region are located corresponding to a side portion of the recording medium.

The present disclosure relates to electronic devices that include a composition that actively generates a gaseous oxidizing agent component within the interior gas space of the electronic device. The present disclosure also involves related methods.

A gas replenishment component for an electronic enclosure is described. A main body defines a containment volume. The main body is sealed about the containment volume. A charging gas is contained in the containment volume. The containment volume has less than 5% N.sub.2. The main body defines a diffusive area that is permeable to the gas. A reversible seal obstructs the diffusive area.

A video coder is configured to form, in a symmetric motion vector difference mode, a List 0 (L0) base vector using a L0 Advanced Motion Vector Prediction (AMVP) candidate list and a List 1 (L1) base vector using a L1 AMVP candidate list; determine a refined L0 motion vector and a refined L1 motion vector by performing a decoder-side motion vector refinement process that refines the L0 base vector and the L1 base vector; and use the refined L0 motion vector and the refined L1 motion vector to determine a prediction block for a current block of a current picture of the video data.
